Academics

+ +

+ I have a Bachelor of Science in Computer Science and graduated from the + College of William and Mary in May of 2018. While there, I participated in + several group software development projects such as hybrid Android application + testing and presided over the campus Game Design Club. +

+ +
+

About Me

+ +

+ I wrote my first program on a TI-84 in BASIC to help finish my high school + math homework faster. I quickly transitioned to building more complicated + programs but have continued to enjoy finding the smallest amount of code to + solve a problem quickly, correctly, and securely. +

+ +

+ I grew up in and still call Hampton Roads, Virginia my home. In my spare time + I drive and maintain a classic car, a 1953 Hudson Hornet. I enjoy travelling + and being at home with my wife and cocker spaniel. I also self-host a web + server in a closet in my home. +

+ +

+ You can always find more on + my web site. +

Why Have a Web Site in 2019?

-
- Adam, why on earth do you have a website? Wait... Is this a - blog? It's 2019, why don't you just use Facebook?! -
- -

- I've wanted to have my own website for a long time mostly because I like - playing with technology. I think it's cool that I can make a few files - on a computer in my closet available for the entire world to see. The - web has become a near-necessity in our daily lives and it's only been - around for a couple of decades. That has always fascinated me enough to - drive me to see if I can do it on my own. I started self-hosting my own - web server about a year ago now and it's been an awesome study in the - way all of the tech we use on the web works. -

- -

- A written website is also a good way to keep up on my writing skills. - I've graduated college and won't be writing essays for the foreseeable - eternity. Which is fine except that I have no reason to write creatively - or formally anymore. Having this site encourages me to continue turning - thoughts into words, even though it's more casual than a term paper. -

- -

- This extends into the professionalism of a personal website. Normally - you can't point your employer towards your Twitter profile as the - distillation of your online footprint. Having a website, especially one - that separates professional and personal interests, is ten times better - than a resume, especially in the world of technology. It lets you tell - people exactly who you are and what you do, without forcing them to - navigate through an auth wall or a bunch of puppy photos. Your - professional and personal lives don't bleed together quite as much and - it makes for a kick-ass business card. -

- -

- Most importantly however, I enjoy the level of control that I gain with - creating and operating my own website, something I have also sought for - a long time. In high school I set up an old Dell from my school's - recycling center with Windows XP and Microsoft Internet Information - Services. It didn't have SSL or even a domain name but it was reachable - over the WAN. I set up an upload system so that my friends and I could - 'post' memes and funny messages for each other on raw html pages written - with Microsoft Word. That was the extent of its functionality. It was - slow, insecure, and went offline every time the router got a new IP - assigned to it. But I didn't care. It was a site the school couldn't - block. It had no name and no rules and nobody could tell us what to do - with it because it was ours. And we called it the - Troll Nexus Center because that's what you do when you're 15 -

- -

- My reasons then for building the Troll Nexus Center still stand now. - Having your own website is having your own piece of internet - property. - I first heard this wording from - Luke Smith over on his YouTube channel - and it's one-hundred percent true. Tumblogs, Google Sites, Facebook - profiles, and GitHub Pages are all like renting an apartment. Sure, - there are some really nice apartments out there but it's not the same as - owning your own home. You have to pay rent obviously, and rent is - subject to change once your lease is up. If anything breaks you text - your landlord and wait to have it fixed. You aren't allowed to fix it - yourself and sometimes it doesn't get fixed at all. And of course you're - limited by how much you can customize things to your own liking. Whether - it's painting walls or knocking them down. -

- -

- These limitations may or may not apply to you. Whether you're paying for - storage, server space, metrics, or watching an ad every five seconds, - these services aren't free either. And you certainly can't fix - everything that goes wrong with them. I started on Google Sites. It's a - truly fantastic system. Building a site is like putting a PowerPoint - slide together. I just plain outgrew it. There were too many things I - wanted to do that I simply couldn't. I was also at the mercy of Google's - constant change. After I finished constructing my first site, Google - announced they would be shutting down the old Google Sites in favor - of an entirely new platform under the same name. Weeks of work got thrown out the window. You might also not care - about ads or customization. You may be intimidated by doing things - yourself and prefer that the landlord take care of everything. - Personally, I like the challenge and the craftsmanship that comes with - doing something myself. And I like being in total control of my server, - site, and content. Not from a tinfoil hat perspective but from a "gosh I - really wish I could just share more than 15 gigabytes of family video - with my relatives in New York and Ohio" perspective. -

- -

- So that's why I created my own website. If you want to know - how I host my own website, look for another post about my - server setup where I'll explain everything I'm hosting and how I got it - all hooked up. And that's a wrap. Now you know why I'm here instead of - somewhere else online. Sure, I do have Facebook and YouTube accounts but - I don't frequently update anything on either of them. This site is my - home online. It's where I keep all of my interests, hobbies, and - memories for sharing with others. -

- -

- Now you know where to find me. If you want to keep up with me, be - old-fashioned and subscribe to my RSS feed. -

How to Start and Drive a Hudson Hornet

- -

- My understanding is there are a lot of people out there for whom driving - a car from the mid-20th century is an oddity, a curiosity, or a life - experience they can't relate to. This is for the non-experts, and - non-Hudsonites to get an idea of what it's like. -

- -

- There are some significant differences between driving the Hornet and - most other cars you come across today. Some of them are just because - there are sixty-six years between the Hudson and the 2019 model year. - Others are Hudson-specific. Many people who I've talked to have said - that they would feel intimidated driving my car (whether that's because - of its perceived complexity or obvious value to me). So, for those who - just want to know how it's done: here is how you start and drive a - Hudson Hornet. -

- -

The Gauge Cluster, Switches, and Controls

- -

- Open the door, slide onto the bench seat, and sit behind the [massive] - steering wheel. For those who haven't experienced it before, it feels - like you have a whole lot of room at your disposal, almost like there - should be more matter occupying the space around you. In front - of you is probably the shiniest dashboard you've ever seen. It's simple, - and probably slightly familiar. -

-

From left to right above the steering wheel you have:

-
    -
  • - A speedometer that tops out at 120 mph (with 99K odometer inside) -
    • -
  • - Fuel and coolant temperature gauges (and two dummy lights; more on - those later) -
    • -
  • A clock
    • -
  • An AM radio
    • -
  • A glove compartment
    • -
- -

From left to right under the steering wheel you have:

-
    -
  • A 2-speed wiper control knob
    • -
  • A weather control (heater) temperature slider
    • -
  • A 2-speed weather control fan knob
    • -
  • The ignition barrel
    • -
  • A headlight switch
    • -
  • - A cigarette-lighter (the owner's manual calls it a cigar lighter!) -
    • -
- -

- Also, underneath the dashboard on the left there is a parking brake - handle and hood latch release and on the right there is an arm which - raises and lowers the fresh air cowl vent. Think of it as "recirculate" - in more modern vehicles. If you're looking for the turn signal lever - it's the tiny stick to the left of the steering wheel. The indicator is - the little yellow light on the far left of the dash. There's only one so - it flashes when you're signalling left or right. We also added our own - air conditioning system, something Hudsons never came with from the - factory. -

- -

Dual-Range Hydramatic

- -

- The first thing that might confuse some folks when they first see the - car running is the shift lever. Many Hornets came with three-speed - manual transmissions that were shifted from the column (overdrive was an - option). However, lots of owners paid extra for the optional "Dual-range - Hydramatic", a fully automatic transmission from General Motors. Truly, - this car has a 4-speed automatic that requires no manual shifting during - normal use, making it that much easier to take a boatload of people to - get milkshakes. -

- -

- Behind the steering wheel is a shift indicator that deviates from the - "PRNDL" pattern most folks are familiar with. From left to right (shift - arm fully at the top to arm fully towards the bottom), the 'gears' are: -

-
    -
  • N (Neutral)
    • -
  • 4-Dr (Drive, all four speeds)
    • -
  • 3-Dr (Drive, three speeds only)
    • -
  • Lo (Low gear)
    • -
  • R (Reverse)
    • -
- -

- Neutral isn't just a mid-way point between reverse and drive in this - car. It's a necessity. With automatic Hornets (and Hydramatics in - general), neutral is used to start the car. There is an electric lockout - preventing the car from being started in any gear but neutral, so you do - have to put the car in neutral before you turn the key (if you're on a - hill put your foot on the brake or engage the parking brake). -

- -

- Drive is split into 4-Dr and 3-Dr, which basically decides whether the - transmission utilizes high gear. In the owner's manual, Hudson - recommends using 3-Dr for driving around town (as the low RPMs delivered - by high gear means unnecessary shifting in and out of 4th gear) and 4-Dr - for highway driving. It really depends on what speed you're going to be - driving at but there isn't anything wrong with driving around in 4 all - the time. I typically leave it in 4th at sustained speeds above 45MPH. - You can switch between these gears any time while moving. -

- -

- Low gear basically locks the transmission in 2nd gear so you don't spin - the wheels. The owner's manual says this is for pulling out of sand or - dirt if you get stuck. -

- -

- Reverse works just about how you might expect but with an added catch: - if the engine is off it acts as park. That's right. When you turn the - car off you can put it in reverse and the transmission will engage a - lock pin to prevent the car from rolling. You can't start the car in - this gear because of the lockout however so you have to shift into - neutral to start the car. So for starting, put it in neutral, for - stopping, put it in reverse. -

- -

Choke and Gas

- -

- For cold starts, our Hornet (and I believe this was common for other - Hudsons of the time) is equipped with an automatic 2-stage choke. Push - the pedal all the way to the floor once to set the choke. After the car - has started and has warmed up, kick the gas quickly to the floor and - release to cancel the choke. -

- -

- For warm starts the engine doesn't need the choke but likes to be given - just a little bit of gas while cranking. -

- -

The Keys, Ignition, and Warning Lights

- -

- Hudsons like mine come with two keys. The octagonal one is for starting - the car, it's used in the ignition. The round one is used for the door - and trunk locks (and I believe in my case the glove box). My - understanding is this is actually reversed from the majority of Hudsons - and is due to a locksmith error at one point or another. -

- -

- The ignition switch sits so that the teeth of the key enter vertically. - Turning the key left powers accessories like the radio. Turning the key - right once switches the car to "ON" which will allow the engine to be - started and remain running. -

- -

- Here's where some things may vary depending on the year of the car. For - '51 Hornets, there's a separate starter button located all the way on - the left control pod. For these cars, you put the key in and turn it to - "ON", and then press and hold the button until the car has started up. - For '52 Hornets onwards, the ignition switch also activates the starter - if you turn the key past "ON" (like in most modern vehicles). -

- -

- If you turn the key to "ON" you'll see two red warning lights appear on - the dash next to the indicators marked "AMP" and "OIL". These are - [alternator] charging status and oil pressure status lights. Our car is - equipped with a 12-V alternator system so the AMP light really comes on - if there is low voltage while the oil pressure light comes on when - there's low oil pressure. These lights will only appear with engine off, - key "ON" or if something has gone very wrong. -

- -

Starting and Driving

- -

- So now that I've gone over the basics of all the components, here is the - normal starting procedure. It actually varies depending on whether the - engine has been warmed up. That's life with carburetors. -

- -

From cold:

- -
    -
  • - Put your foot on the brake, and shift the lever into neutral. Just - push it vertically, pulling towards you slightly if you need to. -
    • -
  • - Push the gas pedal all the way to the floor once and let your foot - back up again to set the choke. -
    • -
  • - Put the key in the ignition and start the car (the "AMP" and "OIL" - lights should switch off. -
    • -
  • - Wait for the engine to smooth out so you know that it's warm enough to - cancel the choke, and kick the gas pedal once to cancel it. (If the - RPMs are still higher than idle then it's not quite at operating - temperature yet) -
    • -
  • - Pull the shifter down into 4-Dr or 3-Dr (or R), and release the - parking brake by twisting the handle towards the steering wheel -
    • -
  • Let off the brake and you're off!
    • -
- -

From warm:

- -
    -
  • Put your foot on the brake and shift into neutral.
    • -
  • - While giving just a little bit of gas, start the car. Both warning - lights should disappear. When the engine fires up you can let off the - gas and let it idle. -
    • -
  • - Pull the shifter into 4-Dr or 3-Dr (or R), and release the parking - brake by twisting the handle towards the steering wheel. -
    • -
  • Done.
    • -
- -

Stopping and Parking

- -
    -
  • - Hold your foot on the brake and twist the parking brake handle towards - the door of the car, and pull it towards you -
    • -
  • - When you're ready to shut off the engine, you can shift it into either - neutral or reverse and turn the key off. Shift it into reverse if you - haven't already to lock the transmission. -
    • -
- -

- Note: I usually engage the parking brake AND put the car in reverse, - just to be safe. If you had to pick one however I would use the - transmission in case you're on a steep hill and your brakes fail for - whatever reason. -

- -

- And there you have it! Not much is different from most cars around today - but there are one or two quirks (more about old cars than about Hudsons - in particular). The only major thing to keep track of while driving is - that you have no power steering, so get ready to anticipate turns sooner - and use more of the wheel with every turn. -

+ My understanding is there are a lot of people out there for whom driving + a car from the mid-20th century is an oddity, a curiosity, or a life + experience they can't relate to. This is for the non-experts, and + non-Hudsonites to get an idea of what it's like. +

+ +

+ There are some significant differences between driving the Hornet and + most other cars you come across today. Some of them are just because + there are sixty-six years between the Hudson and the 2019 model year. + Others are Hudson-specific. Many people who I've talked to have said + that they would feel intimidated driving my car (whether that's because + of its perceived complexity or obvious value to me). So, for those who + just want to know how it's done: here is how you start and drive a + Hudson Hornet. +

+ +

The Gauge Cluster, Switches, and Controls

+ +

+ Open the door, slide onto the bench seat, and sit behind the [massive] + steering wheel. For those who haven't experienced it before, it feels + like you have a whole lot of room at your disposal, almost like there + should be more matter occupying the space around you. In front + of you is probably the shiniest dashboard you've ever seen. It's simple, + and probably slightly familiar. +

+

From left to right above the steering wheel you have:

+
    +
  • + A speedometer that tops out at 120 mph (with 99K odometer inside) +
    • +
  • + Fuel and coolant temperature gauges (and two dummy lights; more on + those later) +
    • +
  • A clock
    • +
  • An AM radio
    • +
  • A glove compartment
    • +
+ +

From left to right under the steering wheel you have:

+
    +
  • A 2-speed wiper control knob
    • +
  • A weather control (heater) temperature slider
    • +
  • A 2-speed weather control fan knob
    • +
  • The ignition barrel
    • +
  • A headlight switch
    • +
  • + A cigarette-lighter (the owner's manual calls it a cigar lighter!) +
    • +
+ +

+ Also, underneath the dashboard on the left there is a parking brake + handle and hood latch release and on the right there is an arm which + raises and lowers the fresh air cowl vent. Think of it as "recirculate" + in more modern vehicles. If you're looking for the turn signal lever + it's the tiny stick to the left of the steering wheel. The indicator is + the little yellow light on the far left of the dash. There's only one so + it flashes when you're signalling left or right. We also added our own + air conditioning system, something Hudsons never came with from the + factory. +

+ +

Dual-Range Hydramatic

+ +

+ The first thing that might confuse some folks when they first see the + car running is the shift lever. Many Hornets came with three-speed + manual transmissions that were shifted from the column (overdrive was an + option). However, lots of owners paid extra for the optional "Dual-range + Hydramatic", a fully automatic transmission from General Motors. Truly, + this car has a 4-speed automatic that requires no manual shifting during + normal use, making it that much easier to take a boatload of people to + get milkshakes. +

  • 4-Dr (Drive, all four speeds)
    • +
  • 3-Dr (Drive, three speeds only)
    • +
  • Lo (Low gear)
    • +
  • R (Reverse)

Offloading GoPro Footage the Easy Way!

- -

- Transferring files off of most cameras to a Linux computer isn't all - that difficult. The exception is my GoPro Hero 4 Black. For 4th of July - week I took a bunch of video with the GoPro, approximately 20 MP4 files, - about 3GB each. The annoying thing about the GoPro's USB interface is - you need additional software to download everything through the cable. - The camera doesn't just show up as a USB filesystem that you can mount. - The GoPro does have a micro-SD card but I was away from home and didn't - have any dongles or adapters. Both of these solutions also mean taking - the camera out of its waterproof case and off of its mount. So here's - what I did. -

- -

- GoPro cameras, after the Hero 3, can open up an ad-hoc wireless network - that lets you browse the GoPro's onboard files through an HTTP server. - This means you can open your browser and scroll through the files on the - camera at an intranet address, 10.5.5.9, and download them - one by one by clicking every link on every page. If you have a lot of - footage on there it kinda sucks. So, I opened up the manual for - wget. I'm sure you could get really fancy with some of the - options but the only thing I cared about was downloading every single - MP4 video off of the camera, automatically. I did not want to download - any of the small video formats or actual HTML files. Here's what I used: -

- - 
-        
-sh wget --recursive --accept "*.MP4" http://10.5.5.9:8080/
-		
-
- -

- This tells wget to download all of the files at the GoPro's - address recursively and skips any that don't have the MP4 extension. Now - I've got a directory tree with all of my videos in it. And the best part - is I didn't have to install the dinky GoPro app on my laptop. Hopefully - this helps if you're looking for an easy way to migrate lots of footage - without manually clicking through the web interface or installing - additional software. The only downside is if you're moving a whole lot - of footage, it's not nearly as quick as just moving files off the SD - card. So I'd shoot for using the adapter to read off the card first and - only use this if that's not an option, such as when the camera is - mounted and you don't want to move it. -

- -

Some things I would like to change/add:

- -
    -
  • - Download all image files as well; should be easy, just another - --accept -
    • -
  • Initiate parallel downloads
    • -
  • - Clean up the directory afterwards so I just have one level of depth -
    • -
- -

- I could probably write a quick and dirty shell script to do all of this - for me but I use the camera so infrequently that it's probably not even - worth it. -

YABS: Yet Another Bad Shop

-

- Today I received a text message from a local mechanic/auto shop asking - me to leave them a Google review. It was an automated message from a - shop that I know well and have used many times in the past. - Unfortunately, I have had several poor experiences (at the time they - seemed horrific) with them in the past year and I can honestly say - they'll never receive my business again. Now I could have used this as - an opportunity to leave them an anonymous nasty-gram but instead I'm - going to do the opposite. I'm going to write about everything I don't - like about them without telling you who they are or hiding who I am. Why - would I do that? Well for one, they were an excellent shop for many - years. I believe a recent change in management is to blame and I'm not - going to ruin their chances of making a comeback (because frankly I - would like for them to rebound). And secondly, I don't believe in - hiding. This page and its author are public knowledge. Now, in no - particular order: a sample of awful work from yet another bad shop. -

- -

Mom's Truck -- Balls Out

- -

- Mom's truck is a 2007 Chrysler Aspen that she loves very much. Dad does - a whole lot of work on it himself (the both of us do pretty much - everything we can in-house so long as we have the right equipment). - We've been taking her truck into this shop for years because we've found - them to be reliable, efficient, and economical. As I said before, at - some point in their recent history they changed hands -- either - ownership or management, I can't remember which. It was around this time - that Dad decided to overhaul Mom's front suspension. He replaced the - ball joints, tie rod ends, and a few other worn out parts. He then did - his own best-guess front-end alignment, but left everything loose so - that YABS could finish up the alignment and tighten everything. Now read - that again because it's important. Dad did his own alignment in our - driveway (as a cost-saving measure), got it decently close, but then - instructed this shop to finish the job and tighten everything up. -

- -

- Now here's where things fall apart. This shop full of professional - mechanics took one look at the alignment Dad did and decided it was good - enough. Hooray for Dad and supernatural mechanical skills, but the shop - didn't even touch the car. They called Dad back to come pick up the car, - telling him it was already good to go. They never tightened a thing, - even after Dad explicitly told them everything was loose and needed to - be tightened but they didn't to touch a thing. So what happened? Dad - picked up the car assuming everything was A-OK and Mom drove the car for - about a week before the two front tires wore down so badly they had to - be replaced immediately. Everything fell out of alignment as things - loosened further and further and the tires wore unevenly until they - ripped themselves to shreds. The worst part? These weren't tires with 6+ - years on them. These were brand new tires. So YABS got to install two - more front tires and then tighten everything. They did not cover the - costs, presumably because it was Dad who had done the alignment. Strike - one. -

- -

Friend's Minivan -- Crude Necessities

- -

- A good friend of ours drives a 2005-2006 Chrysler Town and Country. It - was actually Mom's car before upgrading to the Aspen (the minivan was - perfect in every way but it couldn't tow). Our friend has been using - YABS for just a long as we have. Once again, things started getting - kinda strange after several years of good service. She started getting - charged extra for simple repairs she had them doing very consistently. - They also started tacking on extra items for routine jobs. She would go - in for an inspection and they would claim she needed a new Part X. Now - this in and of itself isn't an uncommon or even strange request to make. - As cars age they need things and sometimes you don't know what they need - until you visit a professional mechanic. They remember the things you - forget about. -

- -

- One day they did all the forgetting, and they forgot a pretty important, - nay, crucial engine component: motor oil. Our friend took her minivan - into YABS for a routine oil change. Good diligence on her part. And - she's not the type to do that change on her own. She's too old to get - under a car anyway (no offense!). So she took the van to YABS and they - did a job they've done thousands of times: drain oil, replaced the - filter, and gave her back the car. Easy peasy right? Now I know I'm not - a professional but I'm thinking someone might have wanted to - double-check that several quarts of synthetic had left the shop shelf - and gone into the car they just backed out of the bay door. Now this - part of the story I'm a little fuzzy on so take it with a large, heaping - grain of salt, but I can say for a fact that they failed to - completely refill the engine oil before returning her car. - Supposedly there was enough in there such that the minivan survived long - enough for them to realize it before she drove off. -

- I decided to give YABS another try after a long leave of absence. I - needed new tires all around for my daily driver. I also needed an - inspection and an alignment. A simple set of tasks for any shop (you see - where this is going). I initially tried to go to another local shop but - they were all out of the tires I was looking to get so I caved and went - to YABS. About halfway through the job they gave me a call and told me - they had some bad news. They said that there were some issues getting - the lug nuts off my wheels and that they had all been stripped, warped, - or otherwise destroyed in the process. They told me the only fix was to - get new ones from a supplier in town for about $160. Keep in mind the - entire job (inspection, tires, etc.) was going to cost $650. - Furthermore, dad and I had no problem getting those lug nuts off and - back on again just a few weeks prior when we changed the transmission - fluid. -

- -

- They didn't have an explanation that I could reconcile with. Joe Schmo - over the phone told me this is typical of Fords and Chryslers these days - and that they'd like to keep my lug nuts for a class action lawsuit - they're participating in. Now why on Earth would any sane mechanic, with - full knowledge they are dealing with a defective set of lug nuts, take a - high power impact wrench to those wheels without speaking with the owner - about it first? Smelled fishy to me honestly. But what was I gonna do? - Dad went out and grabbed twenty new lug nuts for cheaper than they - wanted to sell them for. -

- -

- Oh the tires were Cooper GTs by the way and they're amazing. They're - smooth and quiet and came with a very nice warranty. They're also made - in the USA, which is very important to me. 10/10 would recommend. -

- -

Ol' Blue -- Tunnel Vision

- -

- This was the real kicker. And this one doesn't really have any trailing - narrative. I got four new tires on Ol' Blue, my 1953 Hudson Hornet. They - were delivered to our house: four brand new Diamond Back wide white wall - radials. Super nice tires, with a super nice road hazard warranty (as a - side note I totally recommend you - check out Diamond Back's website if - you're looking for white wall radials). So we brought the car to YABS - with the new tires and asked them to mount them on the car. -

- -

- When we went to pick up the car everything looked great and I drove off. - I made it all the way to the Monitor Merrimack Memorial Bridge Tunnel - before I heard a loud rattling and a bang. I looked in the rear-view - mirror and swore I could see my precious hubcap rolling off to eternity. - When they replaced the hubcaps they didn't fully press one of them on. - And it's not that difficult. These hub caps are very secure when pressed - on the rim, we've never had problems with them. Oh and we're talking - about Hudson hubcaps that came with the car, and aren't super easy to - find. And I couldn't stop to get out and grab it because I was right at - the mouth of the tunnel. We went back later to try and see it but we - couldn't. And it was probably destroyed getting thrown from the car - anyways. -

- -

- The worst part is, the hubcap took a chunk out of my white wall on its - way out from under the wheel skirt. So the day I got the tires I had to - take a picture and redeem my road hazard warranty. Luckily, Diamond Back - were true to their word and sent me a new one no questions asked. The - beat up tire is now my spare. -

- -

Not All Bad

- -

- Like I said before, YABS used to be a very nice shop with friendly - people that did good work. And they didn't charge exorbitant prices for - their work. Times have changed, and I believe management has as well. - I've stopped visiting their shop completely. I found a new one that I - trust and will be taking all of my cars to. They've already done a - safety inspection on Ol' Blue and didn't put up a fuss. They're clean - and friendly and don't seem to be out to screw me. But as with - everything else, your mileage may vary. -

+ Today I received a text message from a local mechanic/auto shop asking + me to leave them a Google review. It was an automated message from a + shop that I know well and have used many times in the past. + Unfortunately, I have had several poor experiences (at the time they + seemed horrific) with them in the past year and I can honestly say + they'll never receive my business again. Now I could have used this as + an opportunity to leave them an anonymous nasty-gram but instead I'm + going to do the opposite. I'm going to write about everything I don't + like about them without telling you who they are or hiding who I am. Why + would I do that? Well for one, they were an excellent shop for many + years. I believe a recent change in management is to blame and I'm not + going to ruin their chances of making a comeback (because frankly I + would like for them to rebound). And secondly, I don't believe in + hiding. This page and its author are public knowledge. Now, in no + particular order: a sample of awful work from yet another bad shop. +

+ +

Mom's Truck -- Balls Out

+ +

+ Mom's truck is a 2007 Chrysler Aspen that she loves very much. Dad does + a whole lot of work on it himself (the both of us do pretty much + everything we can in-house so long as we have the right equipment). + We've been taking her truck into this shop for years because we've found + them to be reliable, efficient, and economical. As I said before, at + some point in their recent history they changed hands -- either + ownership or management, I can't remember which. It was around this time + that Dad decided to overhaul Mom's front suspension. He replaced the + ball joints, tie rod ends, and a few other worn out parts. He then did + his own best-guess front-end alignment, but left everything loose so + that YABS could finish up the alignment and tighten everything. Now read + that again because it's important. Dad did his own alignment in our + driveway (as a cost-saving measure), got it decently close, but then + instructed this shop to finish the job and tighten everything up. +

+ +

+ Now here's where things fall apart. This shop full of professional + mechanics took one look at the alignment Dad did and decided it was good + enough. Hooray for Dad and supernatural mechanical skills, but the shop + didn't even touch the car. They called Dad back to come pick up the car, + telling him it was already good to go. They never tightened a thing, + even after Dad explicitly told them everything was loose and needed to + be tightened but they didn't to touch a thing. So what happened? Dad + picked up the car assuming everything was A-OK and Mom drove the car for + about a week before the two front tires wore down so badly they had to + be replaced immediately. Everything fell out of alignment as things + loosened further and further and the tires wore unevenly until they + ripped themselves to shreds. The worst part? These weren't tires with 6+ + years on them. These were brand new tires. So YABS got to install two + more front tires and then tighten everything. They did not cover the + costs, presumably because it was Dad who had done the alignment. Strike + one. +

+ +

Friend's Minivan -- Crude Necessities

+ +

+ A good friend of ours drives a 2005-2006 Chrysler Town and Country. It + was actually Mom's car before upgrading to the Aspen (the minivan was + perfect in every way but it couldn't tow). Our friend has been using + YABS for just a long as we have. Once again, things started getting + kinda strange after several years of good service. She started getting + charged extra for simple repairs she had them doing very consistently. + They also started tacking on extra items for routine jobs. She would go + in for an inspection and they would claim she needed a new Part X. Now + this in and of itself isn't an uncommon or even strange request to make. + As cars age they need things and sometimes you don't know what they need + until you visit a professional mechanic. They remember the things you + forget about. +

+ +

+ One day they did all the forgetting, and they forgot a pretty important, + nay, crucial engine component: motor oil. Our friend took her minivan + into YABS for a routine oil change. Good diligence on her part. And + she's not the type to do that change on her own. She's too old to get + under a car anyway (no offense!). So she took the van to YABS and they + did a job they've done thousands of times: drain oil, replaced the + filter, and gave her back the car. Easy peasy right? Now I know I'm not + a professional but I'm thinking someone might have wanted to + double-check that several quarts of synthetic had left the shop shelf + and gone into the car they just backed out of the bay door. Now this + part of the story I'm a little fuzzy on so take it with a large, heaping + grain of salt, but I can say for a fact that they failed to + completely refill the engine oil before returning her car. + Supposedly there was enough in there such that the minivan survived long + enough for them to realize it before she drove off. +

Dancing the Shag & The [New] Lion King

-

- Not all of my posts are huge, and they probably shouldn't be. Amy and I - had a really great time yesterday at Two Left Feet Dance Studio, - learning more about how to dance the Carolina Shag in preparation for - our wedding (which is in less than 20 days)! An enormous swing band is - going to play all of our favorites from the brass band/swing era, and - one of the easiest dances to do to that music is the Shag. I wrote a - paper on the Shag a few years ago for school but never actually learned - how to do it. The steps are simple for us to remember and it's easy - enough to add flair or mix it up so we look like we know what we're - doing during our first dance. -

- -

- We also got out to see the new Lion King remake and I can honestly say - it was worth it. If anyone's a Lion King purist, it's Amy. It's easily - been her favorite movie since she was a toddler, and to see it - tastefully redone almost 25 years after it was first released was - thoroughly enjoyable. There were minor alterations to literal sentences - in the script that all added some context to things that were always - kind of assumed in the original (clarification on Scar's backstory, - etc.). I did however feel like they were trying to throw Beyonce lines - the way a middle-schooler tries to turn a 500-word paper into a 700-word - paper. Regardless, it's definitely re-living the classic, not re-hashing - it. -

How I Do Data Recovery

- -

- This week Amy plugged in her flash drive to discover that there were no - files on it. Weeks before there had been dozens of large cuts of footage - that she needed to edit down for work. Hours of recordings were - seemingly gone. And the most annoying part was the drive had worked - perfectly on several other occasions. Just not now that the footage was - actually needed of course. Initially it looked like everything had been - wiped clean, however both Amy's Mac and her PC thought the drive was - half full. It's overall capacity was 64GB but it showed only about 36GB - free. So there still had to be data on there if we could find the right - tool to salvage it. -

- -

- Luckily this wasn't the first time I had to recover accidentally (or - magically) deleted files. I had previously done so with some success at - my tech support job, for some college friends, and for my in-laws' - retired laptops. So I had a pretty clear idea of what to expect. The - only trick was finding a tool that knew what files it was looking for. - The camera that took the video clips was a Sony and apparently they - record into m2ts files, which are kind of a unique format - in that they only show up on Blu-Ray discs and Sony camcorders. Enter my - favorite two tools for dealing with potentially-destroyed data: - ddrescue and photorec. -

- -

DDRescue

- -

- ddrescue is a godsend of a tool. If you've ever used - dd before, forget about it. Use ddrescue. You - might as well alias dd=ddrescue because it's that great. By - default it has a plethora of additional options, displays the progress - as it works, recovers and retries in the event of I/O errors, and does - everything that good old dd can do. It's particularly good - at protecting partitions or disks that have been corrupted or damaged by - rescuing undamaged portions first. Oh, and have you ever had to cancel a - dd operation? Did I mention that ddrescue can - pause and resume operations? It's that good. -

- -

PhotoRec

- -

- photorec is probably the best missing file recovery tool - I've ever used in my entire life. And I've used quite a few. I've never - had as good results as I've had with photorec with other - tools like Recuva et. al. And photorec isn't just for - photos, it can recover documents (a la Office suite), music, images, - config files, and videos (including the very odd - m2ts format!). The other nice thing is - photorec will work on just about any source. It's also free - software which makes me wonder why there are like $50 recovery tools for - Windows that look super sketchy. -

- -

In Practice

- -

- So here's what I did to get Amy's files back. Luckily she didn't write - anything out to the drive afterward so the chances (I thought) were - pretty good that I would get something back. The first thing I - always do is make a full image of whatever media I'm trying to recover - from. I do this for a couple of reasons. First of all it's a backup. If - something goes wrong during recovery I don't have to worry about the - original, fragile media being damaged or wiped. Furthermore, I can work - with multiple copies at a time. If it's a large image that means - multiple tools or even multiple PCs can work on it at once. It's also - just plain faster working off a disk image than a measly flash drive. So - I used ddrescue to make an image of Amy's drive. -

+ This week Amy plugged in her flash drive to discover that there were no + files on it. Weeks before there had been dozens of large cuts of footage + that she needed to edit down for work. Hours of recordings were + seemingly gone. And the most annoying part was the drive had worked + perfectly on several other occasions. Just not now that the footage was + actually needed of course. Initially it looked like everything had been + wiped clean, however both Amy's Mac and her PC thought the drive was + half full. It's overall capacity was 64GB but it showed only about 36GB + free. So there still had to be data on there if we could find the right + tool to salvage it. +

+ +

+ Luckily this wasn't the first time I had to recover accidentally (or + magically) deleted files. I had previously done so with some success at + my tech support job, for some college friends, and for my in-laws' + retired laptops. So I had a pretty clear idea of what to expect. The + only trick was finding a tool that knew what files it was looking for. + The camera that took the video clips was a Sony and apparently they + record into m2ts files, which are kind of a unique format + in that they only show up on Blu-Ray discs and Sony camcorders. Enter my + favorite two tools for dealing with potentially-destroyed data: + ddrescue and photorec. +

+ +

DDRescue

+ +

+ ddrescue is a godsend of a tool. If you've ever used + dd before, forget about it. Use ddrescue. You + might as well alias dd=ddrescue because it's that great. By + default it has a plethora of additional options, displays the progress + as it works, recovers and retries in the event of I/O errors, and does + everything that good old dd can do. It's particularly good + at protecting partitions or disks that have been corrupted or damaged by + rescuing undamaged portions first. Oh, and have you ever had to cancel a + dd operation? Did I mention that ddrescue can + pause and resume operations? It's that good. +

+ +

PhotoRec

+ +

+ photorec is probably the best missing file recovery tool + I've ever used in my entire life. And I've used quite a few. I've never + had as good results as I've had with photorec with other + tools like Recuva et. al. And photorec isn't just for + photos, it can recover documents (a la Office suite), music, images, + config files, and videos (including the very odd + m2ts format!). The other nice thing is + photorec will work on just about any source. It's also free + software which makes me wonder why there are like $50 recovery tools for + Windows that look super sketchy. +

+ +

In Practice

+ +

+ So here's what I did to get Amy's files back. Luckily she didn't write + anything out to the drive afterward so the chances (I thought) were + pretty good that I would get something back. The first thing I + always do is make a full image of whatever media I'm trying to recover + from. I do this for a couple of reasons. First of all it's a backup. If + something goes wrong during recovery I don't have to worry about the + original, fragile media being damaged or wiped. Furthermore, I can work + with multiple copies at a time. If it's a large image that means + multiple tools or even multiple PCs can work on it at once. It's also + just plain faster working off a disk image than a measly flash drive. So + I used ddrescue to make an image of Amy's drive. +

- -

- In January Amy and I bought a house! We couldn't have done it without - the wonderful help of everyone who gave us wedding gifts. We got a nice - little standalone place in Suffolk, much closer to where I work and - centrally located for Amy's tutoring business. We spent all of January - painting and prepping for the big move. Late January and early February - were all moving and unpacking and trying to get back in the groove. - Since the outbreak, we've been using the extra time at home to finish up - all the move-in projects we wanted to: finishing painting, putting up - shelves, hanging pictures, and rewiring electrical outlets. -

- -

- Amy also finally got the chance to pursue her dream job: she started up - her own private tutoring business. She's been working hard with clients - all over Hampton Roads, from college students all the way to - first-graders. Business was booming before schools closed but I know - she'll bring it back once things have returned to normal again. No - worries though, she's spending this time helping William and Mary handle - remote operations and students in need. She's also [supposed to be] - writing her master's thesis so she can graduate in May but you know how - it is. -

Why Computer Science at William and Mary

- -

- Recently a rising high-school senior asked for input on what going to - the College of William and Mary was like for a Computer Science degree. - They were asking about the program itself as well as what it's like on - and off campus. Here's what I sent to them. -

- -

Quick Intro

- -

- I graduated with a Bachelor's in Computer Science from W&M in 2018. - I'm a couple years in the workforce now but can still remember my - experiences well enough to hopefully add my honest opinion on my time - there as well as how it prepared me for my career. I will also add a - little bit about my time on campus in a dorm and off-campus in Colonial - Williamsburg. -

- -

Courses and Curriculum

- -

- I felt very positively about the array of courses that were offered - while I was a student. I took a variety of core prerequisites, just like - everyone else, and a good mix of electives. The courses I took include - Data Structures and Algorithms, Software Development/Engineering, - Computer Organization/Architecture, UNIX Systems Programming, Computer - Graphics/Animation, and Computer and Network Security. This list is not - exhaustive and I'm sure they aren't all offered anymore. I was also - required to take a few math classes (Calc I, II, Discrete Math, Linear - Algebra, and Finite Automata). -

- -

- It is true that the courses listed at cs.wm.edu aren't all - offered at the same time. And it is also true that the higher-level - electives pretty much all required my core prerequisites to be - completed. The result is that the electives all came in my final two - years. My understanding is the curriculum is designed to give someone - the best possible background in computing as a whole. A lot of the - topics may seem like they would never be useful in the "real world" but - I have found the opposite is true. I am an application developer at a - three-letter company. My day-to-day work is building and debugging web - apps, but there's been a lot more to it than that. My first assignment - on the job was scraping bytes off a remote shell and writing a parser to - sift through them. The level of understanding I gathered from my core - classes helped more than I expected they would. I think as a whole they - give me an edge at work and help me teach my colleagues about - algorithms, performance, and systems administration. -

- -

- That being said, course registration was always nightmarish. It was very - difficult to get into the limited seats in the classes I was most - interested in. Eventually the heads of the department had to pass around - a sign up sheet and organize every student into courses, classrooms, and - professors so that seniors would graduate on time and we could all get - something on our schedules. I hope the shortage of teachers has - caught up since I graduated. I learned from a long-time faculty member - that this is largely a result of the exponential growth of incoming CS - degree-seekers. The program has grown very popular in the last ten years - and I like to think grads are catching on to that. -

- -

Teaching

- -

- CS@W&M had neutral to good instructors for me. Some were far worse - than others, as with all subjects. When I was there, lots of the older - faculty were retiring and quickly being replaced with younger, newer - instructors, which added to the growing pains of the program. The most - important thing again was making sure there were enough teachers to - teach all of the students. -

- -

- I know a few of my peers were very upset about what they described as a - lack of communication or availability from their professors. Some have - also mentioned they didn't like having to learn material on their own - and wanted more to come from instruction. I don't deny that the material - itself was difficult and there was a lot of hard work I had to do on my - own to understand very involved concepts in intense, fast-paced courses. - I think that hard work has paid off. I don't think there's realistically - anywhere someone can learn about computing where they won't do any - learning on their own. I am also a very visual, and hands-on learner so - I suppose your mileage may vary. -

- -

- The most important takeaway from this for me was the ability to pick up - new concepts and technologies quickly and apply them productively. The - majority of professors had project-driven courses. Lots of due dates - meant learning how to transform what I read or learned in class into - practical applications in short amounts of time. This has become, - according to those I work with, one of my greater assets. I am - constantly learning new things in my career and I don't have a lecturer - to explain things to me. It's very powerful to have that and I am - thankful for it. It also helps me teach that knowledge to my colleagues - so we can move faster as a team. -

Campus

- -

- I agree with my peers about the conditions of classrooms and buildings - on campus. Some are old. I guess that comes with an old university but - there are a choice few that haven't been kept up as best they could. - Since CS is growing so fast it's also long outgrown its own offices. - Classrooms are scattered throughout every academic building on campus - and I probably had a CS course in at least 80% of them. That meant - jumping from one side of campus to another and back again in between - periods. -

- -

- The College itself isn't too sprawling. I am long-legged and I found I - could get from one end of campus to another in fifteen minutes on foot. - I rode bike a lot to get to classes where I only had ten minutes to do - it. It's also pretty marshy and woodsy in a lot of areas, so during the - rainy season some walking paths got muddy or flooded. Good boots - required. I have never been in as good shape as when I had to do all - that walking but I definitely got soaked and winded making those - transitions. -

- -

- I appreciate history and architecture and was drawn in by the look and - feel of William and Mary as a result. Without getting too romantic, it's - definitely a beautiful place to attend classes. The ancient Wren - building still holds classes and it's a monument to the College's - tradition. However, I really appreciated the modern academic buildings - on the other side of campus where all of the new construction was taking - place. Modern lab equipment and the library lived there. -

- -

- The dorms were nothing to write home about. Lots of them were nested in - the woods and built ages ago so they were a little tired and even dingy. - Others are brand new and well maintained; ask around and get opinions on - which ones to go for first chance you get. I made do with what I got for - the first couple of years by keeping it clean and decorated. My last two - years I lived in a couple of off-campus apartments. It was well worth - the switch. Depending on where you are on campus you may need at least a - bike to access local restaurants, shops, and the grocery store. A bike - is a good idea anyway but it's not necessary for every dorm. -

- -

Colonial Williamsburg

- -

- Lots of my peers didn't appreciate CW as a "college town" but I enjoyed - my time there. I can't speak about parties or clubbing, I was boring and - didn't do any of that. I made a great group of friends and we would walk - into town to get ice cream, see historical attractions (most of which - are free as a student, IIRC), and see movies or plays when we weren't - studying or playing video games in the dorm. There are some good, - sort-of-affordable restaurants but they're kind of driving distance. -

- -

- The best part about living there was meeting my wife. We would go on - long walks to get away from studying and wound up seeing - horse-and-carriages and the Governor's Palace and things like that. We - would also escape with her car to go to some of the surrounding towns to - get away to nice grocery stores and fun places to eat and explore on the - weekends. I also have family in the area so it was easy for me to stop - by home and say hi, although I know lots of students wanted to get as - far away from home as possible. -

Parting Words

- I don't consider myself a gung ho alumnus. There are lots of things I - think could be improved, both in CS and at W&M as a whole but I do - not regret my going there.

+ Recently a rising high-school senior asked for input on what going to + the College of William and Mary was like for a Computer Science degree. + They were asking about the program itself as well as what it's like on + and off campus. Here's what I sent to them. +

+ +

Quick Intro

+ +

+ I graduated with a Bachelor's in Computer Science from W&M in 2018. + I'm a couple years in the workforce now but can still remember my + experiences well enough to hopefully add my honest opinion on my time + there as well as how it prepared me for my career. I will also add a + little bit about my time on campus in a dorm and off-campus in Colonial + Williamsburg. +

+ +

Courses and Curriculum

+ +

+ I felt very positively about the array of courses that were offered + while I was a student. I took a variety of core prerequisites, just like + everyone else, and a good mix of electives. The courses I took include + Data Structures and Algorithms, Software Development/Engineering, + Computer Organization/Architecture, UNIX Systems Programming, Computer + Graphics/Animation, and Computer and Network Security. This list is not + exhaustive and I'm sure they aren't all offered anymore. I was also + required to take a few math classes (Calc I, II, Discrete Math, Linear + Algebra, and Finite Automata). +

+ +

+ It is true that the courses listed at cs.wm.edu aren't all + offered at the same time. And it is also true that the higher-level + electives pretty much all required my core prerequisites to be + completed. The result is that the electives all came in my final two + years. My understanding is the curriculum is designed to give someone + the best possible background in computing as a whole. A lot of the + topics may seem like they would never be useful in the "real world" but + I have found the opposite is true. I am an application developer at a + three-letter company. My day-to-day work is building and debugging web + apps, but there's been a lot more to it than that. My first assignment + on the job was scraping bytes off a remote shell and writing a parser to + sift through them. The level of understanding I gathered from my core + classes helped more than I expected they would. I think as a whole they + give me an edge at work and help me teach my colleagues about + algorithms, performance, and systems administration. +

+ +

+ That being said, course registration was always nightmarish. It was very + difficult to get into the limited seats in the classes I was most + interested in. Eventually the heads of the department had to pass around + a sign up sheet and organize every student into courses, classrooms, and + professors so that seniors would graduate on time and we could all get + something on our schedules. I hope the shortage of teachers has + caught up since I graduated. I learned from a long-time faculty member + that this is largely a result of the exponential growth of incoming CS + degree-seekers. The program has grown very popular in the last ten years + and I like to think grads are catching on to that. +

+ +

Teaching

+ +

+ CS@W&M had neutral to good instructors for me. Some were far worse + than others, as with all subjects. When I was there, lots of the older + faculty were retiring and quickly being replaced with younger, newer + instructors, which added to the growing pains of the program. The most + important thing again was making sure there were enough teachers to + teach all of the students. +

+ +

+ I know a few of my peers were very upset about what they described as a + lack of communication or availability from their professors. Some have + also mentioned they didn't like having to learn material on their own + and wanted more to come from instruction. I don't deny that the material + itself was difficult and there was a lot of hard work I had to do on my + own to understand very involved concepts in intense, fast-paced courses. + I think that hard work has paid off. I don't think there's realistically + anywhere someone can learn about computing where they won't do any + learning on their own. I am also a very visual, and hands-on learner so + I suppose your mileage may vary. +

+ +

+ The most important takeaway from this for me was the ability to pick up + new concepts and technologies quickly and apply them productively. The + majority of professors had project-driven courses. Lots of due dates + meant learning how to transform what I read or learned in class into + practical applications in short amounts of time. This has become, + according to those I work with, one of my greater assets. I am + constantly learning new things in my career and I don't have a lecturer + to explain things to me. It's very powerful to have that and I am + thankful for it. It also helps me teach that knowledge to my colleagues + so we can move faster as a team. +

+ +

Now This is a Minimal Install!

- -

- I just got done configuring Poudriere on Freebsd 12.1-RELEASE. The - awesome thing about it is it allows you to configure and maintain your - own package repository. All of the ports and their dependencies are - built from source with personalized options. That means that I can - maintain my own repo of just the packages I need with just the - compile-time options I need. For example, for the Nvidia driver set I - disabled all Wayland related flags. I use Xorg so there was no need to - have that functionality built in. -

- -

- Compile times are pretty long but I hope to change that by upgrading my - home server to FreeBSD as well (from Ubuntu Server). Then I can - configure poudriere to serve up a ports tree and my own pkg repo from - there. The server is a lot faster than my laptop and will build packages - way faster, and I'll be able to use those packages on both the server - and my laptop and any jails I have running. Jails (and ZFS) also make - poudriere really cool to use as all of the building is done inside a - jail. When the time comes I can just remove the jail and poudriere ports - tree from my laptop and update pkg to point to my web server. -

- -

- This is, as I understand it, the sane way to do package management in - FreeBSD. The binary package repo is basically the ports tree - pre-assembled with default options. Sometimes those packages are - compiled without functionality that most users don't need. In those - situations, you're forced to use ports. The trouble is you're not really - supposed to mix ports and binary packages. The reason, again as I - understand it, is because ports are updated more frequently. So binary - packages and ports can have different dependency versions, which can - sometimes break compatibility on an upgrade. Most FreeBSD users - recommend installing everything with ports (which is just a make install - inside the local tree) but then you lose the package management features - that come with pkg. Poudriere lets you kind of do both by creating your - "own personal binary repo" out of a list of preconfigured, pre-built - ports. -

- -

FreeBSD rocks.

AOC 2020 Day 1 in CBM Basic

- -

- I implemented the - Advent of Code 2020 Day 1 - challenge in CBM BASIC on a real Commodore 64. I haven't done anything - in Basic in a long time, and probably never did anything actually - meaningful with it. Part 1 of the challenge was to take a list of - numbers, find the two that summed to 2020, and then multiply those two - numbers together. Part two was to perform part 1 but with three numbers - instead of two. -

-

- Now I wanted to actually write the code on the Commodore 64 itself, but - I gave myself some leniency. Instead of manually typing in all 200 - entries of input data (and inevitably making a breaking mistake) I used - Vim on my PC to format the DATA entries at the start of the - code. I then dropped that onto a 1541 disk image, plopped it on an SD - card, and used my SD2IEC to mount the SD card's image on the Commodore. - The rest of the programming was done on the Commodore itself. -

- -

Here is my solution for Day 1 Part 1:

+ I implemented the + Advent of Code 2020 Day 1 + challenge in CBM BASIC on a real Commodore 64. I haven't done anything + in Basic in a long time, and probably never did anything actually + meaningful with it. Part 1 of the challenge was to take a list of + numbers, find the two that summed to 2020, and then multiply those two + numbers together. Part two was to perform part 1 but with three numbers + instead of two. +

+

+ Now I wanted to actually write the code on the Commodore 64 itself, but + I gave myself some leniency. Instead of manually typing in all 200 + entries of input data (and inevitably making a breaking mistake) I used + Vim on my PC to format the DATA entries at the start of the + code. I then dropped that onto a 1541 disk image, plopped it on an SD + card, and used my SD2IEC to mount the SD card's image on the Commodore. + The rest of the programming was done on the Commodore itself. +

Useful Sprint Planning from a Certified Scrum Master

- -

- This is a small collection of sprint planning/story points allocation - tips and tricks that I use at work. They pretty much all come from our - in-house certified "Scrum Master". He's got much better experience than - I do with building a real working backlog of stories and planning - sprints based on those stories. That being said, any opinions here are - my own and I don't speak on his behalf. -

Points as a Measure of Work

- -

- In my understanding, points are approximate measures of the amount of - work required to complete a given story or task. I do not think points - correlate to an exact measure of time. I use them to determine the size - of a task in relation to another task. For example, a simple-looking - task may be allocated 1 point. In reality this 1 point may take 1 minute - or 1 hour to complete. The time it takes is less important than the - ratio of time it takes in comparison to a second given task. Say the - second task appears to take twice as much time as the first (however - much time that may be). The second task would therefore get 2 points. -

- Some teams have a special system for incrementing points. Our team uses - the - Fibonacci sequence of numbers. So the smallest amount that can be allocated to a story is 1. Then it - goes 2, 3, 5, 8, and so on and so forth. If a single story is going to - use up 8 points, you should probably take a look at breaking it up into - smaller tasks. A single story shouldn't take up almost half of your - allocated work for a sprint. -

- -

How Much is Enough?

-

- Our team aims for 10 points per 2-week per sprint. Simple enough for me, - but the hard part is determining how many points to allocate to a given - task. -

- -

- One thing I could never figure out is what the recommended starting - position for 1 point looks like. I'm sure this is something that comes - from experience, and our Scrum Master helped us out with that. -

- -
    -
  • - 1 point: Small or basic text change. Updating configuration, fixing a - typo or cognitively simple bug. -
    • -
  • - 2 points: Task with light complexity. Some portions of code have to - change, be debugged, tested. -
    • -
  • - 3 points: Some complexity, will take time to implement. Potentially a - few days' worth of work. May require front- and back-end work, or - back-end and database work. -
    • -
  • - 5 points: Half a sprint's worth of more complicated work. Full-on - feature implementation for example. -
    • -
- -

Prioritizing Work

- -

- I do not see points as indicative of the importance or priority of a - task or story. Just because one task will take longer to complete than - another does not mean it's more or less important to me. There should be - another method of gauging which stories should be taken off the backlog - first. For example, one story might depend on another. One might relate - to core functionality that a stakeholder has asked for. Another task - might be required to make code build because it solves some major - problem! -

- -

- To communicate how "important" a task is, every story we have is - prioritized something like this: -

-
    -
  1. Critical
    2. -
  2. Blocker
    3. -
  3. Highest
    4. -
  4. High
    5. -
  5. Medium
    6. -
  6. Low
    7. -
  7. Lowest
    8. -
- -

- Tasks that align with some long-term project that management is waiting - on are tagged "Highest". Stories that prevent lots of other stories from - being completed may be labeled "Blocker". -

- -

Sprint Planning/Backlog Refinement

- -

- With all that in mind, at the start of the sprint I now take about 10 - points worth of priority work off of the backlog. I'll work through it - the whole sprint through and then, ideally, it'll all be complete by the - end of the sprint. If I bit off more than I could chew and the sprint - ends before I'm finished, the incomplete work rolls over to the next - sprint and is the first to be completed. If I find I've finished - everything I had to work on and there are still a couple of days left in - the sprint, I'll take one or two small items off the backlog and work on - those. -

- -

Tools to Get the Job Done

- -

- Our team uses Jira at work, and I know some folks love it so much - they've paid for a personal license. It's a bit overkill for my personal - projects, so I've been using Nextcloud's Deck plugin. This is an okay - solution but it doesn't integrate very well with source code - repositories (although it can tie into a Nextcloud "project", or a - collection of related files open to a team). I'm spinning up a Gitea - server to replace my git-web server soon and this is one of - the reasons for that. Gitea has a GitHub-style issue tracker where you - can create issues of various kinds, assign them to users, reference - commits to the source, and create a Kanban-style board of issues that - are on the backlog, to-do, in-progress, or done. -

- -

- I'm still learning how to keep to a Scrum-like process of some kind, - because I do see the benefit of using such a system, especially in a - team. I'm definitely not an expert though so some of what I've got here - may change over time. Right now it's working well and that's good enough - for me. -

Points as a Measure of Work

+ +

+ In my understanding, points are approximate measures of the amount of + work required to complete a given story or task. I do not think points + correlate to an exact measure of time. I use them to determine the size + of a task in relation to another task. For example, a simple-looking + task may be allocated 1 point. In reality this 1 point may take 1 minute + or 1 hour to complete. The time it takes is less important than the + ratio of time it takes in comparison to a second given task. Say the + second task appears to take twice as much time as the first (however + much time that may be). The second task would therefore get 2 points. +

Why Does Everyone Use Adobe Acrobat [Reader]?

- -

- -

- -

- This is something that I've never been able to figure out. All through - high school I had to use PDFs. And if you wanted to open a PDF, everyone - understood that you needed Adobe Acrobat Reader. Even web sites where - you downloaded PDFs insisted that in order to open them, you were going - to have to follow a download link to make sure you have Acrobat on your - PC. -

- -

- Fast-forward a few years into college and I'm using PDFs more than ever. - Every professor ever is scanning and uploading course material, so out - comes Acrobat Reader for literally every teacher and student. At this - point I was actually used to using Firefox (PDF.js) to view PDFs for a - couple of reasons. First of all, Firefox usually opened PDFs faster than - Acrobat Reader did. Reader was getting bigger with every release, and - eventually had a monstrous UI to load up every time I wanted to open a - tiny PDF file. Second, Firefox had smooth scrolling for page-width - documents. Reader was getting slower and laggier with each release, to - the point where scrolling through a PDF was no longer buttery smooth but - jittery and stuttery. It also seemed like Reader purposefully wouldn't - slide the page when you used a mouse wheel. It would jump down a few - lines at a time like it was simulating the down arrow. -

- -

- By my senior year I had switched from Windows to Linux full-time and it - was then I found out about MuPDF and - from then on things were never the same. It's literally the best PDF - reader I've ever used, and I tried out quite a few. There are desktop - and mobile apps. It opens almost instantly. It lets you easily resize - the page with excellent keyboard shortcuts. There are no giant menu bars - on either side of the page to squish the document down to an unreadable - size. Having a dozen of them open at once doesn't bog down my PC. It's - also available for all of the relevant operating systems I've used - (Windows, Mac OS, Linux, FreeBSD)! Oh and password-protected PDFs are - supported as well. -

- -

- It's a fantastic piece of software And the best part is it comes with a - variety of tools to edit and manipulate PDFs as well. If the folks I - went to school with thought you needed the free Acrobat Reader to view a - PDF, they sure as heck thought you needed to buy Acrobat Pro to edit - one. Some of them refused to pay for it and used a variety of online - services to upload, split or merge, and download PDFs. I honestly for - the life of me can't understand why. MuPDF comes with - mutool, which does all of the things I would ever need to - do with a PDF. It can attempt to convert a PDF to other formats, like - HTML. It can split and combine documents. It can even create them from - scratch and sign them. -

- -

- It's also free and open source. Can you imagine that? PDF viewing and - editing being free and open source? It's AGPL (in addition to being - commercially) licensed by the creators. The only slight drawback is the - desktop version apparently does not yet let you fill out forms. Not sure - why but this isn't something I use very frequently. -

- -

- It's not the hottest piece of tech out there, but it just plain works - and works really well. Maybe the only reason more people I know don't - use it is because Adobe is synonymous with the PDF format. It doesn't - seem like that big of a deal, but I feel like Acrobat has always been a - piece of software that has frustrated new or infrequent users in - computing. And that's just not good. Maybe the barrier to using MuPDF is - the lack of GUI and abundance of keybindings, but for me that's no - sweat. I'd say to anyone to just try it out and see if they like it. It - is free, after all. -

Antivirus Software is a Hack

Ranum's The Six Dumbest Ideas in Computer Security, and I highly recommend reading through the whole thing. It's got - great anecdotes and really simple language for what I consider to be - some of the obvious issues with the way programmers and sysadmins think - about security (myself included).

- -
- hack
- 1. n. Originally, a quick job that produces what is needed, but not - well. -
- -- The Jargon File (version 4.4.7, 29 Dec 2003) [jargon] -
- -

- This is the Jargon File's definition of a hack. And to me, this is what - antivirus software is. Antivirus software, as I understand it, emerged - in the mid to late 1980s and became prolific in the 1990s. In the 2000s - it was considered an essential piece of software and people were paying - for yearly subscriptions for antivirus suites from Norton, Avast, and - McAfee. -

- -

- The most basic functionality of an antivirus program is to determine - whether malware exists on a host operating system. The typical method of - doing this is to use a collection of virus definitions and compare each - and every potentially-infected file with each and every definition to - determine whether the file is malware or has been infected by some. An - over-simplified way of implementing this is to store a collection of - hashes, each taken from a known potentially unwanted program or - infectious executable. You can then hash entire files or portions of - files and compare the checksums to see whether a file contains or is - equivalent to the definition, and is therefore infected and shouldn't be - executed. Some security suites go beyond this with heuristic matching, - but if you run an antivirus that has to "update definitions" on a - routine basis, it probably works something like this*. With any luck, it - does it without being a total detriment to system performance. Ideally - it also doesn't act like a piece of malware itself by making itself near - impossible to remove (looking at you, McAfee). -

- -

- To me, a virus definition database is "enumerating badness" (Ranum's - Dumb Idea #2). The premise is that it is not only logical but even - possible to compile a list of all potentially unwanted - programs, viruses, ransomware, and worms. An environment of trust should - be built around the programs that you want to run (read: - allow to run), not the other way around. Picture an operating - system where no binary file can be executed unless it is specifically - flagged as being allowed to. Oh and picture also being able to restrict - this execution to just the file's owner, or other groups of users. - Wouldn't it be easier to store the list of 30 odd programs that you and - other system users trust to be run than the thousands (millions?) of - programs that are infectious, forbidden, or unwanted? What about when - those trusted applications become compromised? Would it not also be - easier to maintain a list of checksums for those binaries and compare - those checksums before they're executed to make sure they haven't been - infected or replaced? -

- -

- The answer is yes, it would be easier. And yes, it is easier. Of course, - your system has to work that way. Antivirus software is a hack because - it's a hack-y solution to a problem that has a better, simpler solution. - It also has the potential for making a ton of money but I won't go into - that. It's easier to enumerate goodness, to specifically open up to a - select few trustworthy applications. Good lists are usually shorter than - bad lists. This builds on top of Ranum's Dumb Idea #1: Default Permit. - You wouldn't configure a firewall to just block some known bad ports and - traffic. You configure it to block all of it, and then whitelist the - ones you know you can trust. You wouldn't configure a browser ad-blocker - to permit all ads, and select the ones you don't want to see. You block - all of them! Then, if there are sites or ads you're okay with seeing, - you whitelist them. You shouldn't default permit all programs to be - given control over your computer, and then meticulously list the ones - that don't have that permission. -

- -

- Oh and of course, as always, there's free software that lets you do - this. You don't have to pay for an antivirus suite, or even use an - unpaid one that slows down your computer or barrages you with ads. On - the BSDs and virtually all Linux distributions, there are built-in tools - to control access and execution of binaries. There are additional tools - that you can install that check whether binaries (in locations like - /bin or /usr/local/bin have been modified - since you last used them. On Windows, the story is a little different. - Most home Windows 10 users are automatically allowed to install and run - any software they want to by default. Windows Server does have Software - Restriction Policies that allow you to create a "default deny" policy - and whitelist only the software that's allowed to run. If you're using a - home edition you probably have to look for software that lets you do - this. I haven't tried any of them so I'm not going to endorse or even - name them here. -

- -

- Preventing malware from running on your system is a problem. Solving - this problem is the right thing to do. But please, try to solve it the - right way. I stopped using an antivirus after I moved out and got to - control my own computer. I don't think it ever did me any good besides - flag false positives (a lot of the time with programs or applications - that I wrote, which weren't malicious in any way!) and grind my spinning - disk to a halt. Evaluate what software you use. Is most of it online? - Are there one or two applications that you know you need to use? How - often do you install and use unknown or untrusted software? Odds are you - can come up with a list of very few programs that you want or need to - use. If it's less than 100,000, you're probably better off with a - default deny policy than an antivirus suite. -

- -

- * What I didn't mention here is that as soon as a new piece of malware - is constructed, if it's different enough from its predecessors, it's - impervious to all antivirus suites on the planet that don't have it in - their definitions. So until that malware is used, detected, and added to - the list, it has free reign. -

On + the BSDs and virtually all Linux distributions, there are built-in tools + to control access and execution of binaries. There are additional tools + that you can install that check whether binaries (in locations like + /bin or /usr/local/bin have been modified + since you last used them. On Windows, the story is a little different. + Most home Windows 10 users are automatically allowed to install and run + any software they want to by default. Windows Server does have Software + Restriction Policies that allow you to create a "default deny" policy + and whitelist only the software that's allowed to run. If you're using a + home edition you probably have to look for software that lets you do + this. I haven't tried any of them so I'm not going to endorse or even + name them here. +

+ +

+ Preventing malware from running on your system is a problem. Solving + this problem is the right thing to do. But please, try to solve it the + right way. I stopped using an antivirus after I moved out and got to + control my own computer. I don't think it ever did me any good besides + flag false positives (a lot of the time with programs or applications + that I wrote, which weren't malicious in any way!) and grind my spinning + disk to a halt. Evaluate what software you use. Is most of it online? + Are there one or two applications that you know you need to use? How + often do you install and use unknown or untrusted software? Odds are you + can come up with a list of very few programs that you want or need to + use. If it's less than 100,000, you're probably better off with a + default deny policy than an antivirus suite. +

+ +

+ * What I didn't mention here is that as soon as a new piece of malware + is constructed, if it's different enough from its predecessors, it's + impervious to all antivirus suites on the planet that don't have it in + their definitions. So until that malware is used, detected, and added to + the list, it has free reign. +

    -
    • -
  • - Lowry, Lois. The Giver -

    - Second time I got to read this. Fantastic book just the same as - before. Movie was totally carried by the fact that Jeff Bridges is - the Giver. Super thought-provoking too. -

    -
    • -
  • - Miller, Rand, Miller, Robyn, Miller, David. - Myst: The Book of Atrus, Myst: The Book of Ti'ana -

    - The great first two books in the Myst novel series. My favorite is - the second, it gives all of the meat-and-potatoes lore behind the - D'ni, The Art, and The Fall that I always wanted.

    -
    • -
  • - Paulsen, Gary. Hatchet -

    - The last time I read this was probably in the sixth grade, and it - was one of the few books I was really glued to then. It's still a - great story about survival, nature, getting mauled by moose, etc. -

    -
    • -
  • - Grisham, John. Theodore Boone: Kid Lawyer -

    - Also a re-read for me. I kind of sort of wanted to be a lawyer - growing up and this book was the "I can do it too!" book. It's still - a good crime, evidence, trial style lawyer book. I need to read the - sequels. -

    -
    • -
  • - Wells, H.G. - The Time Machine, The Island of Dr. Moreau, The Invisible Man -

    - These are three of my favorite H.G. Wells novels. - The Time Machine is super weird though and now that I'm - re-reading it I'm picking up on a ton of Communist undertones. - Dr. Moreau is fantastic. I love all books that take place - on a desert island and this one really creeps me out with the - doctor's surgically-humanized animals. Invisible Man is so - short it's worth reading on a weekend just to know what it's about - (spoiler: a man who is invisible). -

    -
    • -
  • - Stevenson, Robert Louis. Treasure Island -

    - Dude, I watched Treasure Planet when I was a kid and I was really - into it for like a month. Now I finally got to read the real thing - and there's a reason why this is one of those perfect examples of - literature. It's the - absolute perfect, truly American story - about pirates, treasure, and sailing ships. -

    -
    • -
  • - Dick, Harold G. - The Golden Age of the Great Passenger Airships: Graf Zeppelin and - Hindenburg -

    - I'm a huge rigid airship junkie. They're freaking awesome, I wish - they were still around. I hate flying, and not because of the act of - being in the air but because airships make it seem more comfortable, - luxurious, and adventurous than a half a bag of peanuts, motion - sickness, and recycled oxygen. If you're at all interested in - Zeppelins and you can only read one book, this is the - only book worth reading. It chronicles the author's - experiences actually flying on and operating Graf Zeppelin and - Hindenburg, their flight logs, how they worked, how they were flown, - and the history behind their creation and demise. It's awesome. -

    -
    • -
  • - Brown, Dan. Digital Fortress -

    - Great story, I actually listened to this audiobook while painting - our house right around the start of 2020. It's an awesome story with - an intelligent, sleuthy programmer and her globe-trotting professor - significant other tracking down clues. It's got supercomputers and - hackers and espionage and murder and viruses and it would be perfect - if I knew nothing about cryptography or computing in general. -

Root on ZFS: A ZPool of Mirror VDEVs

- -

- I wanted/needed to make a root on ZFS pool out of multiple mirror VDEVs, - and since I'm not a ZFS expert, I took a little shortcut. -

- -

- I recently got a new-to-me server (yay!) and I wanted to do a - root-on-ZFS setup on it. I've really enjoyed using ZFS for my data - storage pools for a long time. I've also enjoyed the extra functionality - that comes with having a bootable system installed on ZFS on my laptop - and decided with this upgrade it's time to do the same on my server. - Historically I've used RAIDZ for my storage pools. RAIDZ functions - almost like a RAID10 but at the ZFS level. It gives you parity so that a - certain number of disks can die from your pool and you won't lose any - data. It does have a few tradeoffs however*, and for personal - preferences I've decided that for the future I would like to have a - single ZPool over top of multiple mirror VDEVs. In other words, my main - root+storage pool will be made up of two-disk mirrors and can be - expanded to include any number of new mirrors I can fit into the - machine. -

- -

- This did present some complications. First of all, - bsdinstall won't set this up for you automatically (and - sure enough, - in the handbook - it mentions the guided root on ZFS tool will only create a single, - top-level VDEV unless it's a stripe). It will happily let you use RAIDZ - for your ZROOT but not the more custom approach I'm taking. I did - however use - bsdinstall as a shortcut so I wouldn't have to do all of - the partitioning and pool setup manually, and that's what I'm going to - document below. Because I'm totally going to forget how this works the - next time I have to do it. -

- -

- In my scenario I have an eight-slot, hot-swappable PERC H310 controller - that's configured for AHCI passthrough. In other words, all FreeBSD sees - is as many disks as I have plugged into the backplane. I'm going to fill - it with 6x2TB hard disks which, as I said before, I want to act as three - mirrors (two disks each) in a single, bootable, growable ZPool. For - starters, I shoved the FreeBSD installer on a flash drive and booted - from it. I followed all of the regular steps (setting hostname, getting - online, etc.) until I got to the guided root on ZFS disk partitioning - setup. -

- -

- Now here's where I'm going to take the first step on my shortcut. Since - there is no option to create the pool of arbitrary mirrors I'm just - going to create a pool from a single mirror VDEV of two disks. Later I - will expand the pool to include the other two mirrors I had intended - for. My selections were as follows: -

- -
    -
  • Pool Type/Disks: mirror mfisyspd0 mfisyspd1
    • -
  • Pool Name: zroot
    • -
  • Partition Scheme: GPT (EFI)
    • -
  • Swap Size: 4g
    • -
- -

- Everything else was left as a default. Then I followed the installer to - completion. At the end, when it asked if I wanted to drop into a shell - to do more to the installation, I did. -

- -

- The installer created the following disk layout for the two disks that I - selected. -

- -

-  3907028992         136             - free -  (68K)
-
-
- -

- The installer also created the following ZPool from my single mirror - VDEV. -

- - 
-
-atc@macon:~ % zpool status
-  pool: zroot
- state: ONLINE
-  scan: none requested
-config:

-	    mfisyspd1p3  ONLINE       0     0     0
-
-errors: No known data errors
-
-
- -

- There are a couple of things to take note of here. First of all, - both disks in the bootable ZPool have an EFI boot partition. - That means they're both a part of (or capable of?) booting the pool. - Second, they both have some swap space. Finally, they both have a third - partition which is dedicated to ZFS data, and that partition is what got - added to my VDEV. -

- -

- So where do I go from here? I was tempted to just - zpool add mirror ... ... and just add my other disks to the - pool (actually, I did do this but it rendered the volume - unbootable for a very important reason), but then I wouldn't have those - all-important boot partitions (using whole-disk mirror VDEVS). Instead, - I need to manually go back and re-partition four disks exactly like the - first two. Or, since all I want is two more of what's already been done, - I can just clone the partitions using gpart backup and - restore! Easy! Here's what I did for all four remaining - disks: -

- - 
-
-root@macon:~ # gpart backup mfisyspd0 | gpart restore -F mfisyspd2`
-
-
- -

- Full disclosure, I didn't even think of this as a possibility - until I read this Stack Exchange post. This gave me a disk layout like this: -

- And to be fair, this makes a lot of logical sense. You don't want a - six-disk pool to only be bootable by two of the disks or you're - defeating some of the purposes of redundancy. So now I can extend my - ZPool to include those last four disks. -

- -

- This next step may or may not be a requirement. I wanted to overwrite - where I assumed any old ZFS/ZPool metadata might be on my four new - disks. This could just be for nothing and I admit that, but I've run - into trouble in the past where a ZPool wasn't properly - exported/destroyed before the drives were removed for another purpose - and when you use those drives in future - zpool imports, you can see both the new and the old, failed - pools. And, in the previous step I cloned an old ZFS partition many - times! So I did a small dd on the remaining disks to help - me sleep at night: -

- - 
-
-root@macon:~ # dd if=/dev/zero of=/dev/mfisyspd2 bs=1M count=100
-
-
- -

- One final, precautionary step is to write the EFI boot loader to the new - disks. In - zpool admin handbook - it mentions you should do this any time you replace a zroot - device, so I'll do it just for safe measure on all four additional - disks: -

- - 
-
-root@macon:~ # gpart bootcode -p /boot/boot1.efifat -i 1 mfisyspd2

- Boom. A growable, bootable zroot ZPool. Is it easier than just - configuring the partitions and root on ZFS by hand? Probably not for a - BSD veteran. But since I'm a BSD layman, this is something I can live - with pretty easily. At least until this becomes an option in - bsdintall maybe? At least now I can add as many more - mirrors as I can fit into my system. And it's just as easy to replace - them. This is better for me than my previous RAIDZ, where I would have - to destroy and re-create the pool in order to add more disks to the - VDEV. Now I just create another little mirror and grow the pool and all - of my filesystems just see more storage. And of course, having ZFS for - all of my data makes it super easy to create filesystems on the fly, - compress or quota them, and take snapshots (including the live ZROOT!) - and send those snapshots over the network. Pretty awesome. -

- * I'm not going to explain why here, but - this is a pretty well thought out article - that should give you an idea about the pros and cons of RAIDZ versus - mirror VDEVs so you can draw your own conclusions. -

+ I wanted/needed to make a root on ZFS pool out of multiple mirror VDEVs, + and since I'm not a ZFS expert, I took a little shortcut. +

+ +

+ I recently got a new-to-me server (yay!) and I wanted to do a + root-on-ZFS setup on it. I've really enjoyed using ZFS for my data + storage pools for a long time. I've also enjoyed the extra functionality + that comes with having a bootable system installed on ZFS on my laptop + and decided with this upgrade it's time to do the same on my server. + Historically I've used RAIDZ for my storage pools. RAIDZ functions + almost like a RAID10 but at the ZFS level. It gives you parity so that a + certain number of disks can die from your pool and you won't lose any + data. It does have a few tradeoffs however*, and for personal + preferences I've decided that for the future I would like to have a + single ZPool over top of multiple mirror VDEVs. In other words, my main + root+storage pool will be made up of two-disk mirrors and can be + expanded to include any number of new mirrors I can fit into the + machine. +

+ +

+ This did present some complications. First of all, + bsdinstall won't set this up for you automatically (and + sure enough, + in the handbook + it mentions the guided root on ZFS tool will only create a single, + top-level VDEV unless it's a stripe). It will happily let you use RAIDZ + for your ZROOT but not the more custom approach I'm taking. I did + however use + bsdinstall as a shortcut so I wouldn't have to do all of + the partitioning and pool setup manually, and that's what I'm going to + document below. Because I'm totally going to forget how this works the + next time I have to do it. +

+ +

+ In my scenario I have an eight-slot, hot-swappable PERC H310 controller + that's configured for AHCI passthrough. In other words, all FreeBSD sees + is as many disks as I have plugged into the backplane. I'm going to fill + it with 6x2TB hard disks which, as I said before, I want to act as three + mirrors (two disks each) in a single, bootable, growable ZPool. For + starters, I shoved the FreeBSD installer on a flash drive and booted + from it. I followed all of the regular steps (setting hostname, getting + online, etc.) until I got to the guided root on ZFS disk partitioning + setup. +

+ +

+ Now here's where I'm going to take the first step on my shortcut. Since + there is no option to create the pool of arbitrary mirrors I'm just + going to create a pool from a single mirror VDEV of two disks. Later I + will expand the pool to include the other two mirrors I had intended + for. My selections were as follows: +

+ +
    +
  • Pool Type/Disks: mirror mfisyspd0 mfisyspd1
    • +
  • Pool Name: zroot
    • +
  • Partition Scheme: GPT (EFI)
    • +
  • Swap Size: 4g
    • +
+ +

+ Everything else was left as a default. Then I followed the installer to + completion. At the end, when it asked if I wanted to drop into a shell + to do more to the installation, I did. +

+ +

+ The installer created the following disk layout for the two disks that I + selected. +

+ +

+  3907028992         136             - free -  (68K)
+
+
+ +

+ The installer also created the following ZPool from my single mirror + VDEV. +

+ +
+
+atc@macon:~ % zpool status
+  pool: zroot
+ state: ONLINE
+  scan: none requested
+config:
+
+	NAME             STATE     READ WRITE CKSUM

+	    mfisyspd0p3  ONLINE       0     0     0
+	    mfisyspd1p3  ONLINE       0     0     0
+
+errors: No known data errors
+
+
+ +

+ There are a couple of things to take note of here. First of all, + both disks in the bootable ZPool have an EFI boot partition. + That means they're both a part of (or capable of?) booting the pool. + Second, they both have some swap space. Finally, they both have a third + partition which is dedicated to ZFS data, and that partition is what got + added to my VDEV. +

+ +

+ So where do I go from here? I was tempted to just + zpool add mirror ... ... and just add my other disks to the + pool (actually, I did do this but it rendered the volume + unbootable for a very important reason), but then I wouldn't have those + all-important boot partitions (using whole-disk mirror VDEVS). Instead, + I need to manually go back and re-partition four disks exactly like the + first two. Or, since all I want is two more of what's already been done, + I can just clone the partitions using gpart backup and + restore! Easy! Here's what I did for all four remaining + disks: +

+ +
+
+root@macon:~ # gpart backup mfisyspd0 | gpart restore -F mfisyspd2`
+
+
+ +

+ Full disclosure, I didn't even think of this as a possibility + until I read this Stack Exchange post. This gave me a disk layout like this: +

+ And to be fair, this makes a lot of logical sense. You don't want a + six-disk pool to only be bootable by two of the disks or you're + defeating some of the purposes of redundancy. So now I can extend my + ZPool to include those last four disks. +

+ +

+ This next step may or may not be a requirement. I wanted to overwrite + where I assumed any old ZFS/ZPool metadata might be on my four new + disks. This could just be for nothing and I admit that, but I've run + into trouble in the past where a ZPool wasn't properly + exported/destroyed before the drives were removed for another purpose + and when you use those drives in future + zpool imports, you can see both the new and the old, failed + pools. And, in the previous step I cloned an old ZFS partition many + times! So I did a small dd on the remaining disks to help + me sleep at night: +

+ +
+
+root@macon:~ # dd if=/dev/zero of=/dev/mfisyspd2 bs=1M count=100
+
+
+ +

+ One final, precautionary step is to write the EFI boot loader to the new + disks. In + zpool admin handbook + it mentions you should do this any time you replace a zroot + device, so I'll do it just for safe measure on all four additional + disks: +

+ +
+
+root@macon:~ # gpart bootcode -p /boot/boot1.efifat -i 1 mfisyspd2
+
+
+ +

+ Don't forget that the command is different for UEFI and a traditional + BIOS. And finally, I can add my new VDEVs: +

+ +
+
+root@macon:~ # zpool zroot add mirror mfisyspd2p3 mfisyspd3p3
+root@macon:~ # zpool zroot add mirror mfisyspd4p3 mfisyspd5p3
+
+
+ +

Louis Vierne Is a BAMF (and Proof That Organists Are Metal)

- -

- Louis Vierne is a certifiable badass organist from the end of the 19th - and early 20th centuries. He was born blind and had to have surgery to - be able to distinguish shapes and objects. Did that stop him from - playing the one instrument that literally requires you to distinguish - hundreds and hundreds of small objects from each other? Nope, he just - did it (and he learned from Cesar Franck, another great organist). -

- -

- In 1906 he got hit by a car and the doctors said they might have to - amputate his leg. Did you know you play an organ with both your hands - and both your feet? Well you do, and Vierne just re-learned how - to play with his feet after the accident. Because nobody tells Louis - Vierne no. -

- -

- And because he's a badass, Vierne went on to become the official - organist at the Notre Dame in Paris, a position he won by competitively - dunking on numerous other musicians. He considered this his greatest - achievement, and what Louis Vierne says goes. -

- -

- In one final act of badassery, he carried out his lifelong dream: to die - while playing at Notre Dame. In 1937, to a full recital hall in Notre - Dame, he was giving his 1,750th performance and actually - had a heart-attack while playing and died at the console, and keeled - over so that the low "E" played until they removed his body. To this day, no rock band has ever been so metal. -

- -
- -

- Alright, so without the decoration, Louis Vierne is my favorite Organist - and composer from the period. The organ is, in my opinion, the coolest - instrument on the planet. It's the biggest, the loudest, and the most - impressive. It's also got the most wide and interesting array of sounds, - like having an orchestra at your fingertips. Vierne made some of my - favorite music for the organ (music that my lowly organ skills will - never let me play). He's also, obviously, pretty badass. -

- -

- In truth, I think all organists are pretty cool. They play a cool, - complicated instrument that really sounds like no other. They also play - with their hands and their feet. Someone once said when a musician mates - with an octopus, an organist is born. Come to think of it, Davy Jones - plays the Organ and he's pretty cool. Coincidence? I think not. -

- -

- If you get the chance, give Vierne a listen, you can look up his work on - YouTube or a Pandora Radio station in his name. Look especially for - Symphony No. 1 for Organ in D Minor, Op. 14. That's the first song I - heard of his live (and in my understanding is the one he was playing - when he died). -

How to Automate Certbot Renewal with HAProxy

- -

- So this is specifically for HAProxy on FreeBSD, but it should apply to - other *nix systems as well. Basically, I use HAProxy as a reverse proxy - to a bunch of servers I administer. I use Let's Encrypt for a - certificate and I used certbot to generate that - certificate. Generating the certificate for the first time is easy and - has lots of documentation, but it wasn't initially clear on how I could - easily set up auto-renewal. Here's how I did it. -

- -

- If you've already set up TLS termination with HAProxy and - certbot, you know you need to combine your Let's Encrypt - fullchain and private key to get a combined certificate that HAProxy can - use. You can do this by cat-ing the chain and key together - like so: -

- - 
-
-cat /usr/local/etc/letsencrypt/live/$SITE/fullchain.pem /usr/local/etc/letsencrypt/live/$SITE/privkey.pem > /usr/local/etc/ssl/haproxy.pem
-
-
- -

- In this example, $SITE is your domain name that you fed - HAProxy when you created the certificate and haproxy.pem is - wherever you're storing HAProxy's combined certificate. Your HAProxy - config then points to that certificate like this: -

- - 
-
-macon% grep crt /usr/local/etc/haproxy.conf
-        bind *:443 ssl crt /usr/local/etc/ssl/haproxy.pem
-
-
- -

- And that was the end of the first-time setup. Then a few months later - you probably had to do it again because Let's Encrypt certs are only - good for 90 days in between renewals. To renew the certificate, you - usually run certbot renew, it detects which certificates - are present, and uses either the webroot or standlone server renewal - process. Then you have to cat the fullchain and privkey - together and restart HAProxy so it starts using the new certificate. -

- -

- To automate those steps, newer versions of - certbot will run any post renewal hooks (read: scripts) - that you want. You can also configure HAProxy and - certbot to perform the ACME challenge dance for renewal so - that you don't have to use it interactively. -

- -

- First, if you haven't already done it, change your HAProxy config so - there's a frontend+backend for responding to ACME challenges. In a - frontend listening for requests, create an access control list for any - request looking for /.well-known/acme-challenge/. Send - those requests to a backend server with an unused local port. -

- - 
-
-frontend http-in
-		acl letsencrypt-acl path_beg /.well-known/acme-challenge/
-        use_backend letsencrypt-backend if letsencrypt-acl
-		...
-backend letsencrypt-backend
-		server letsencrypt 127.0.0.1:54321
-
-
- -

- What this will do is allow certbot and Let's Encrypt to - renew your server in standalone mode via your reverse proxy. As an added - bonus it prevents you from having to open up an additional port on your - firewall. -

- -

- Now you've gotta configure certbot to do just that. A - config file was created in certbot's - renew directory for your site. All you need to do in that - file is add a line to the [renewalparams] section - specifying the port you're using in your HAProxy config. -

- - 
-
-macon% echo "http01_port = 54321" >> /usr/local/etc/letsencrypt/renewal/$SITE.conf
-
-
- -

- Now you need the post-renewal hooks. I dropped two separate scripts into - the renewal-hooks directory: one does the job of combining - the certificate chain and private key and the other just restarts - HAProxy. -

- - 
-
-macon% cat /usr/local/etc/letsencrypt/renewal-hooks/post/001-catcerts.sh
-#!/bin/sh
-
-SITE=(your site of course)
-
-cd /usr/local/etc/letsencrypt/live/$SITE
-cat fullchain.pem privkey.pem > /usr/local/etc/ssl/haproxy.pem
-macon% cat /usr/local/etc/letsencrypt/renewal-hooks/post/002-haproxy.sh
-#!/bin/sh
-service haproxy restart
-
-
- -

- When certbot renew is run, certbot checks the - renewal-hooks/post directory and runs any executable things - in it after it's renewed the certificate(s). As a side note, - make sure you hit those scripts with chmod +x or - they probably won't run. -

- -

- Now all that's left is dropping a job into cron or - periodic to run certbot renew at least once or - twice within the renewal period. -

- - 
-
-macon% doas crontab -l|grep certbot
-# certbot renewal
-@monthly certbot renew
-
-
- -

- You can always test that your scripts are working with - certbot renew --dry-run just to be safe. -

How to Make Your Website Boring and Why!

- -

- I took the time last year to make my website more boring. Here's how you - can do the same and why you'd want to. -

- -

- Up until recently I was using a static site generator - (cobalt-rs) and a fancy CSS framework/library (Bulma) to - build my website. I also had one or two scripts to do various fiddly - things in the browser. I took the time to gut it and now I have a much - more boring website. I don't use anything but HTML to write all of the - posts and pages. This eliminated the need for a static generator or - script to turn something like Markdown into HTML for me. I also scrapped - all of the customized CSS framework style sheets that I had been using - for a very small (145 lines including whitespace and braces) single-file - stylesheet. I also dropped all of the fancy links, banners, most of the - icons, and any JavaScript that I had originally. Now, my site is much - more boring. And it's so much better. -

- -

How does one make their website boring?

- -

- Typically, ask yourself whether you need something. If the answer is - "no", you can safely remove it and you won't need it again. Your website - will become more boring (read: simpler). Here are some of the things I - evaluated: -

- -
    -
  • - How many 3rd-party assets, templates, CSS libraries am I using? How - big are they? Are they slowing down rendering or annoying to - maintain/upgrade? -
    • -
  • Do I need a Sass interpreter to "build" my styles?
    • -
  • - Am I using a static site generator? Does it make my life easier or - more difficult? -
    • -
  • - Am I using a bunch of JavaScript? What does it do and does it really - need to do it to make my site work better? -
    • -
- -

- Do you use a lot of third-party assets, templates, or CSS for your site? - Do you have to run a SASS tool to generate your stylesheets? Are your - stylesheets really big (> 1000 lines I think anyone would consider on - the bigger side)? Consider whether or not you really need them. - Oftentimes, with CSS, less is more. Especially if your site is just a - collection of pages of text with links to other pages of text. You can - make your site attractive and compatible with 100% of browsers by - keeping things simple. And then you don't have to worry about rebuilding - your output stylesheets or keeping up with libraries and frameworks. -

- -

- Do you have a lot of dynamically-generated content on your site? Does - the document need to change based on user input? Do you have a large - number of script tags importing minified files from third-party CDNs? - Odds are you don't need those either and you can completely get rid of - them. Now you don't have to worry about making sure all browsers can run - those scripts, or whether or not the CDNs are online, or you're - requesting the latest version. -

- -

- Do you use a static site generator to build your site? Is your content - complicated enough to write that you can't write it in plain HTML? Is - Markdown really easier or more powerful? Odds are, it's easier to write - directly in HTML without having to tell your generator what to do with - your tags. And for the oddball tag that Markdown doesn't directly - support, you might often end up writing HTML into your Markdown files - anyways. And, you can better control what the output formatting looks - like, making your site's code more readable. Furthermore, you won't have - two acting copies of your site, a pre- and post-generator one. For me, - it was annoying having "source code" for my web site that was different - from what I was actually hosting. It's so much nicer to have a 1:1 - mapping between what I write, test, and deploy. -

- -

- Still not convinced? Still need to automate some part of building your - site, like generating an RSS feed? Is there any chance you can write a - quick Makefile to do that for you? I was able to do just that, and it - was way nicer not having to install and learn how a generator worked to - automate assembling my site. -

- -

- If you answered "no" to any of the above "do you need"-s, you just found - a way to make your site more boring. Boring equates with simplicity. - Simplicity is a good thing. -

- -

Why should you make your website boring simple?

- -

- Not relying on a bunch of libraries and assets is a good thing. It - seemed like every time I wanted to add a quick post, I would notice - there was an update for some library I was using and I was spending time - upgrading and learning about it. You know, that thing that computer - programmers enjoy doing and are good at but often doesn't actually help - them accomplish anything: fiddling with shiny new stuff that doesn't - solve a problem. Now I get to just focus on adding things to my site and - I'm never worried about whether it looks broken. -

+ I took the time last year to make my website more boring. Here's how you + can do the same and why you'd want to. +

+ +

+ Up until recently I was using a static site generator + (cobalt-rs) and a fancy CSS framework/library (Bulma) to + build my website. I also had one or two scripts to do various fiddly + things in the browser. I took the time to gut it and now I have a much + more boring website. I don't use anything but HTML to write all of the + posts and pages. This eliminated the need for a static generator or + script to turn something like Markdown into HTML for me. I also scrapped + all of the customized CSS framework style sheets that I had been using + for a very small (145 lines including whitespace and braces) single-file + stylesheet. I also dropped all of the fancy links, banners, most of the + icons, and any JavaScript that I had originally. Now, my site is much + more boring. And it's so much better. +

+ +

How does one make their website boring?

+ +

+ Typically, ask yourself whether you need something. If the answer is + "no", you can safely remove it and you won't need it again. Your website + will become more boring (read: simpler). Here are some of the things I + evaluated: +

+ +
    +
  • + How many 3rd-party assets, templates, CSS libraries am I using? How + big are they? Are they slowing down rendering or annoying to + maintain/upgrade? +
    • +
  • Do I need a Sass interpreter to "build" my styles?
    • +
  • + Am I using a static site generator? Does it make my life easier or + more difficult? +
    • +
  • + Am I using a bunch of JavaScript? What does it do and does it really + need to do it to make my site work better? +
    • +
+ +

+ Do you use a lot of third-party assets, templates, or CSS for your site? + Do you have to run a SASS tool to generate your stylesheets? Are your + stylesheets really big (> 1000 lines I think anyone would consider on + the bigger side)? Consider whether or not you really need them. + Oftentimes, with CSS, less is more. Especially if your site is just a + collection of pages of text with links to other pages of text. You can + make your site attractive and compatible with 100% of browsers by + keeping things simple. And then you don't have to worry about rebuilding + your output stylesheets or keeping up with libraries and frameworks. +

+ +

+ Do you have a lot of dynamically-generated content on your site? Does + the document need to change based on user input? Do you have a large + number of script tags importing minified files from third-party CDNs? + Odds are you don't need those either and you can completely get rid of + them. Now you don't have to worry about making sure all browsers can run + those scripts, or whether or not the CDNs are online, or you're + requesting the latest version. +

+ +

+ Do you use a static site generator to build your site? Is your content + complicated enough to write that you can't write it in plain HTML? Is + Markdown really easier or more powerful? Odds are, it's easier to write + directly in HTML without having to tell your generator what to do with + your tags. And for the oddball tag that Markdown doesn't directly + support, you might often end up writing HTML into your Markdown files + anyways. And, you can better control what the output formatting looks + like, making your site's code more readable. Furthermore, you won't have + two acting copies of your site, a pre- and post-generator one. For me, + it was annoying having "source code" for my web site that was different + from what I was actually hosting. It's so much nicer to have a 1:1 + mapping between what I write, test, and deploy. +

+ +

+ Still not convinced? Still need to automate some part of building your + site, like generating an RSS feed? Is there any chance you can write a + quick Makefile to do that for you? I was able to do just that, and it + was way nicer not having to install and learn how a generator worked to + automate assembling my site. +

+ +

+ If you answered "no" to any of the above "do you need"-s, you just found + a way to make your site more boring. Boring equates with simplicity. + Simplicity is a good thing. +

+ +

Why should you make your website boring simple?

+ +

+ Not relying on a bunch of libraries and assets is a good thing. It + seemed like every time I wanted to add a quick post, I would notice + there was an update for some library I was using and I was spending time + upgrading and learning about it. You know, that thing that computer + programmers enjoy doing and are good at but often doesn't actually help + them accomplish anything: fiddling with shiny new stuff that doesn't + solve a problem. Now I get to just focus on adding things to my site and + I'm never worried about whether it looks broken. +

+ +

+ I also didn't like having a pre- and post-build site. If I wanted to fix + one typo I couldn't remote into my live site, fix it, and then leave it + there. I had to do something like fix the typo in my Markdown, commit + and push it, and then re-run the generator and upload the new "live" + files. The generator step wasn't making things easier, it was making + them more annoying. +

Web Designers, Please Don't "Animate" Page Titles

- -

- If you visit - Express Oil Change's web site, - everything seems completely ordinary until you leave the tab. That's - when the most distracting, broken, annoying example of over-the-top web - "design" rears its ugly head. -

- -

- I'm talking about this scrolling page title. In my tab. Constantly - moving from right to left to show me all of the text. It's the only tab - that's "moving" or "animated" and it doesn't stop until you return to - the tab. It's cheesy and gaudy. -

- -

- -

- -

- And it's also broken because there are emojis in the page title and the - title is obviously being "scrolled" by some script that's moving - byte-by-byte, so it scrolls halfway through a multi-byte UTF-8 emoji and - for a brief moment there's a glyph error character where a little red - car should have been. Bad judgment and bad programming. Worse than that, - even if it worked perfectly, it's incredibly annoying. -

- -

- -

- -

- If you bookmark the tab when it's in the middle of scrolling, you'll - bookmark this weird slice of the text that starts or ends in the middle - of a word or with a random emoji. -

- -

- -

- -

- Page titles changing is typically used to notify the user that their - action is needed, such as when a file is finished uploading. In this - case, since the text is constantly changing, the tab is always - in a state of "urgency." Most annoyingly, this causes the browser to - highlight the tab when it's pinned. Even if you click the tab and leave - it, this notification reappears. -

- -

- -

- -

- Don't do this. Stop. Get some help. It's distracting. It's the cheesy - "web dev" equivalent of retina scan advertising in Minority Report. Just - make a site that works and looks half decent without slowing to a halt - and stop there please. -
