This is for the non-experts, and - non-Hudsonites to get an idea of what it's like. - </p> - - <p> - 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. - </p> - - <h2>The Gauge Cluster, Switches, and Controls</h2> - - <p> - 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 - <em>should</em> 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. - </p> - <p>From left to right above the steering wheel you have:</p> - <ul> - <li> - A speedometer that tops out at 120 mph (with 99K odometer inside) - </li> - <li> - Fuel and coolant temperature gauges (and two dummy lights; more on - those later) - </li> - <li>A clock</li> - <li>An AM radio</li> - <li>A glove compartment</li> - </ul> - - <p>From left to right under the steering wheel you have:</p> - <ul> - <li>A 2-speed wiper control knob</li> - <li>A weather control (heater) temperature slider</li> - <li>A 2-speed weather control fan knob</li> - <li>The ignition barrel</li> - <li>A headlight switch</li> - <li> - A cigarette-lighter (the owner's manual calls it a cigar lighter!) - </li> - </ul> - - <p> - 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. - </p> - - <h2>Dual-Range Hydramatic</h2> - - <p> - 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. - </p> - - <p> - 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: - </p> - <ul> - <li>N (Neutral)</li> - <li>4-Dr (Drive, all four speeds)</li> - <li>3-Dr (Drive, three speeds only)</li> - <li>Lo (Low gear)</li> - <li>R (Reverse)</li> - </ul> - - <p> - 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). - </p> - - <p> - 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. - </p> - - <p> - 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. - </p> - - <p> - 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. - </p> - - <h2>Choke and Gas</h2> - - <p> - 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. - </p> - - <p> - For warm starts the engine doesn't need the choke but likes to be given - just a little bit of gas while cranking. - </p> - - <h2>The Keys, Ignition, and Warning Lights</h2> - - <p> - 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. - </p> - - <p> - 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. - </p> - - <p> - 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). - </p> - - <p> - 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. - </p> - - <h2>Starting and Driving</h2> - - <p> - 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. - </p> - - <h3>From cold:</h3> - - <ul> - <li> - Put your foot on the brake, and shift the lever into neutral. Just - push it vertically, pulling towards you slightly if you need to. - </li> - <li> - Push the gas pedal all the way to the floor once and let your foot - back up again to set the choke. - </li> - <li> - Put the key in the ignition and start the car (the "AMP" and "OIL" - lights should switch off. - </li> - <li> - 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) - </li> - <li> - 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 - </li> - <li>Let off the brake and you're off!</li> - </ul> - - <h3>From warm:</h3> - - <ul> - <li>Put your foot on the brake and shift into neutral.</li> - <li> - 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. - </li> - <li> - Pull the shifter into 4-Dr or 3-Dr (or R), and release the parking - brake by twisting the handle towards the steering wheel. - </li> - <li>Done.</li> - </ul> - - <h2>Stopping and Parking</h2> - - <ul> - <li> - Hold your foot on the brake and twist the parking brake handle towards - the door of the car, and pull it towards you - </li> - <li> - 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. - </li> - </ul> - - <p> - 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. - </p> - - <p> - 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. - </p> - </article> - </body> -</html> diff --git a/posts/2019-06-07-how-to-start-and-drive-a-hudson-hornet.php b/posts/2019-06-07-how-to-start-and-drive-a-hudson-hornet.php new file mode 100644 index 0000000..53e0f40 --- /dev/null +++ b/posts/2019-06-07-how-to-start-and-drive-a-hudson-hornet.php @@ -0,0 +1,267 @@ +<?php +$title = "How to Start and Drive a Hudson Hornet"; +if (isset($early) && $early) { + return; +} +include($_SERVER['DOCUMENT_ROOT'] .

It's simple, + and probably slightly familiar. +</p> +<p>From left to right above the steering wheel you have:</p> +<ul> + <li> + A speedometer that tops out at 120 mph (with 99K odometer inside) + </li> + <li> + Fuel and coolant temperature gauges (and two dummy lights; more on + those later) + </li> + <li>A clock</li> + <li>An AM radio</li> + <li>A glove compartment</li> +</ul> + +<p>From left to right under the steering wheel you have:</p> +<ul> + <li>A 2-speed wiper control knob</li> + <li>A weather control (heater) temperature slider</li> + <li>A 2-speed weather control fan knob</li> + <li>The ignition barrel</li> + <li>A headlight switch</li> + <li> + A cigarette-lighter (the owner's manual calls it a cigar lighter!) + </li> +</ul> + +<p> + 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. +</p> + +<h2>Dual-Range Hydramatic</h2> + +<p> + 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. +</p> + +<p> + 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: +</p> +<ul> + <li>N (Neutral)</li> + <li>4-Dr (Drive, all four speeds)</li> + <li>3-Dr (Drive, three speeds only)</li> + <li>Lo (Low gear)</li> + <li>R (Reverse)</li> +</ul> + +<p> + 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). +</p> + +<p> + 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. +</p> + +<p> + 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. +</p> + +<p> + 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. +</p> + +<h2>Choke and Gas</h2> + +<p> + 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. +</p> + +<p> + For warm starts the engine doesn't need the choke but likes to be given + just a little bit of gas while cranking. +</p> + +<h2>The Keys, Ignition, and Warning Lights</h2> + +<p> + 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. +</p> + +<p> + 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. +</p> + +<p> + 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). +</p> + +<p> + 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. +</p> + +<h2>Starting and Driving</h2> + +<p> + 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. +</p> + +<h3>From cold:</h3> + +<ul> + <li> + Put your foot on the brake, and shift the lever into neutral. Just + push it vertically, pulling towards you slightly if you need to. + </li> + <li> + Push the gas pedal all the way to the floor once and let your foot + back up again to set the choke. + </li> + <li> + Put the key in the ignition and start the car (the "AMP" and "OIL" + lights should switch off. + </li> + <li> + 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) + </li> + <li> + 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 + </li> + <li>Let off the brake and you're off!</li> +</ul> + +<h3>From warm:</h3> + +<ul> + <li>Put your foot on the brake and shift into neutral.</li> + <li> + 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. + </li> + <li> + Pull the shifter into 4-Dr or 3-Dr (or R), and release the parking + brake by twisting the handle towards the steering wheel. + </li> + <li>Done.</li> +</ul> + +<h2>Stopping and Parking</h2> + +<ul> + <li> + Hold your foot on the brake and twist the parking brake handle towards + the door of the car, and pull it towards you + </li> + <li> + 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. + </li> +</ul> + +<p> + 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. +</p> + +<p> + 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. +</p> diff --git a/posts/2019-07-04-the-best-way-to-transfer-gopro-files-with-linux.html b/posts/2019-07-04-the-best-way-to-transfer-gopro-files-with-linux.html deleted file mode 100644 index 8a0e587..0000000 --- a/posts/2019-07-04-the-best-way-to-transfer-gopro-files-with-linux.html +++ /dev/null @@ -1,127 +0,0 @@ -<!DOCTYPE html> -<html lang="en"> - <head> - <link rel="stylesheet" href="/includes/stylesheet.css" /> - <meta charset="utf-8" /> - <meta name="viewport" content="width=device-width, initial-scale=1" /> - <meta - property="og:description" - content="The World Wide Web pages of Adam Carpenter" - /> - <meta property="og:image" content="https://nextcloud.53hor.net/index.php/s/Nx9e7iHbw4t99wo/preview" /> - <meta property="og:site_name" content="53hor.net" /> - <meta - property="og:title" - content="Offloading GoPro Footage the Easy Way!" - /> - <meta property="og:type" content="website" /> - <meta property="og:url" content="https://www.53hor.net" /> - <title>53hornet ➙ Offloading GoPro Footage the Easy Way!</title> - </head> - - <body> - <nav> - <ul> - <li> - <a href="/"> - <img alt="home" src="/includes/icons/home-roof.svg" /> - Home - </a> - </li> - <li> - <a href="/info.html"> - <img alt="information" src="/includes/icons/information-variant.svg" /> - Info - </a> - </li> - <li> - <a href="https://git.53hor.net"> - <img alt="git" src="/includes/icons/git.svg" /> - Repos - </a> - </li> - <li> - <a href="/software.html"> - <img alt="software" src="/includes/icons/floppy-variant.svg" /> - Software - </a> - </li> - <li> - <a type="application/rss+xml" href="/rss.xml"> - <img alt="rss" src="/includes/icons/rss.svg" /> - RSS - </a> - </li> - </ul> - </nav> - - <article> - <h1>Offloading GoPro Footage the Easy Way!</h1> - - <p> - Transferring files off of most cameras to a Linux computer isn't all - that difficult.

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. - </p> - - <h2>Mom's Truck -- Balls Out</h2> - - <p> - 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. - </p> - - <p> - 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. - </p> - - <h2>Friend's Minivan -- Crude Necessities</h2> - - <p> - 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. - </p> - - <p> - 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 - <em>completely</em> 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. - </p> - - <h2>Monty, My 2013 Ford Focus -- Nut Allergy</h2> - - <p> - 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. - </p> - - <p> - 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. - </p> - - <p> - 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. - </p> - - <h2>Ol' Blue -- Tunnel Vision</h2> - - <p> - 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 - <a href="https://dbtires.com/">check out Diamond Back's website</a> 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. - </p> - - <p> - 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. - </p> - - <p> - 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. - </p> - - <h2>Not All Bad</h2> - - <p> - 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. - </p> - </article> - </body> -</html> diff --git a/posts/2019-07-04-yabs-yet-another-bad-shop.php b/posts/2019-07-04-yabs-yet-another-bad-shop.php new file mode 100644 index 0000000..9594369 --- /dev/null +++ b/posts/2019-07-04-yabs-yet-another-bad-shop.php @@ -0,0 +1,183 @@ +<?php +$title = "YABS: Yet Another Bad Shop"; +if (isset($early) && $early) { + return; +} +include($_SERVER['DOCUMENT_ROOT'] .

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. +</p> + +<h2>Mom's Truck -- Balls Out</h2> + +<p> + 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. +</p> + +<p> + 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. +</p> + +<h2>Friend's Minivan -- Crude Necessities</h2> + +<p> + 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. +</p> + +<p> + 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 + <em>completely</em> 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. +</p> + +<h2>Monty, My 2013 Ford Focus -- Nut Allergy</h2> + +<p> + 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. +</p> + +<p> + 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. +</p> + +<p> + 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. +</p> + +<h2>Ol' Blue -- Tunnel Vision</h2> + +<p> + 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 + <a href="https://dbtires.com/">check out Diamond Back's website</a> 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. +</p> + +<p> + 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. +</p> + +<p> + 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. +</p> + +<h2>Not All Bad</h2> + +<p> + 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. +</p> diff --git a/posts/2019-07-21-dancing-the-shag-and-the-new-lion-king.html b/posts/2019-07-21-dancing-the-shag-and-the-new-lion-king.html deleted file mode 100644 index 8fb1dfb..0000000 --- a/posts/2019-07-21-dancing-the-shag-and-the-new-lion-king.html +++ /dev/null @@ -1,94 +0,0 @@ -<!DOCTYPE html> -<html lang="en"> - <head> - <link rel="stylesheet" href="/includes/stylesheet.css" /> - <meta charset="utf-8" /> - <meta name="viewport" content="width=device-width, initial-scale=1" /> - <meta - property="og:description" - content="The World Wide Web pages of Adam Carpenter" - /> - <meta - property="og:image" - content="https://nextcloud.53hor.net/index.php/s/Nx9e7iHbw4t99wo/preview" - /> - <meta property="og:site_name" content="53hor.net" /> - <meta - property="og:title" - content="Dancing the Shag & The [New] Lion King" - /> - <meta property="og:type" content="website" /> - <meta property="og:url" content="https://www.53hor.net" /> - <title>53hornet ➙ Dancing the Shag & The [New] Lion King</title> - </head> - - <body> - <nav> - <ul> - <li> - <a href="/"> - <img alt="home" src="/includes/icons/home-roof.svg" /> - Home - </a> - </li> - <li> - <a href="/info.html"> - <img - alt="information" - src="/includes/icons/information-variant.svg" - /> - Info - </a> - </li> - <li> - <a href="https://git.53hor.net"> - <img alt="git" src="/includes/icons/git.svg" /> - Repos - </a> - </li> - <li> - <a href="/software.html"> - <img alt="software" src="/includes/icons/floppy-variant.svg" /> - Software - </a> - </li> - <li> - <a type="application/rss+xml" href="/rss.xml"> - <img alt="rss" src="/includes/icons/rss.svg" /> - RSS - </a> - </li> - </ul> - </nav> - - <article> - <h1>Dancing the Shag & The [New] Lion King</h1> - <p> - Not all of my posts are huge, and they probably shouldn't be.

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. - </p> - - <p> - 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 <code>m2ts</code> 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: - <code>ddrescue</code> and <code>photorec</code>. - </p> - - <h2>DDRescue</h2> - - <p> - <code>ddrescue</code> is a godsend of a tool. If you've ever used - <code>dd</code> before, forget about it. Use <code>ddrescue</code>. You - might as well <code>alias dd=ddrescue</code> 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 <code>dd</code> 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 - <code>dd</code> operation? Did I mention that <code>ddrescue</code> can - pause and resume operations? It's that good. - </p> - - <h2>PhotoRec</h2> - - <p> - <code>photorec</code> 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 <code>photorec</code> with other - tools like Recuva et. al. And <code>photorec</code> isn't just for - photos, it can recover documents (a la Office suite), music, images, - config files, and videos (including the very odd - <code>m2ts</code> format!). The other nice thing is - <code>photorec</code> will work on just about any source. It's also free - software which makes me wonder why there are like $50 recovery tools for - Windows that look super sketchy. - </p> - - <h2>In Practice</h2> - - <p> - So here's what I did to get Amy's files back. Luckily she didn't write - anything out to the drive afterward so the chances (I thought) were - pretty good that I would get <em>something</em> back. The first thing I - always do is make a full image of whatever media I'm trying to recover - from. I do this for a couple of reasons. First of all it's a backup. If - something goes wrong during recovery I don't have to worry about the - original, fragile media being damaged or wiped. Furthermore, I can work - with multiple copies at a time. If it's a large image that means - multiple tools or even multiple PCs can work on it at once. It's also - just plain faster working off a disk image than a measly flash drive. So - I used <code>ddrescue</code> to make an image of Amy's drive. - </p> - - <pre><code> -$ sudo ddrescue /dev/sdb1 amy-lexar.dd -GNU ddrescue 1.24 -Press Ctrl-C to interrupt - ipos: 54198 kB, non-trimmed: 0 B, current rate: 7864 kB/s - opos: 54198 kB, non-scraped: 0 B, average rate: 18066 kB/s -non-tried: 63967 MB, bad-sector: 0 B, error rate: 0 B/s - rescued: 54198 kB, bad areas: 0, run time: 2s -pct rescued: 0.08%, read errors: 0, remaining time: 59m - time since last successful read: n/a -Copying non-tried blocks...

Here's what I sent to them. - </p> - - <h2>Quick Intro</h2> - - <p> - 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. - </p> - - <h2>Courses and Curriculum</h2> - - <p> - 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). - </p> - - <p> - It is true that the courses listed at <code>cs.wm.edu</code> 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. - </p> - - <p> - 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 - <em>something</em> 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. - </p> - - <h2>Teaching</h2> - - <p> - 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. - </p> - - <p> - 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. - </p> - - <p> - 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. - </p> - - <h2>Campus</h2> - - <p> - 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. - </p> - - <p> - 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. - </p> - - <p> - 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. - </p> - - <p> - 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. - </p> - - <h2>Colonial Williamsburg</h2> - - <p> - 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. - </p> - - <p> - 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. - </p> - - <h2>Parting Words</h2> - - <p> - 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. There is no such thing as "everything is - great" or "everything is terrible". It's not so definitive. I had my - fair share of gripes and at times it strained me. There were pros and - cons but I think I have a lot to be thankful for (I landed my job - through W&M recruiting and the career center as well, which are - fantastic resources). I cannot say "do this instead of that." I haven't - gone to any other colleges and don't know enough about them to recommend - them as better or worse. What I can recommend is the same path I took - for folks who want to pursue a degree in Computer Science.

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. - </p> - - <p> - 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. - </p> - - <p> - 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.

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. - </p> - - <h2>Points as a Measure of Work</h2> - - <p> - 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. - </p> - - <p> - Some teams have a special system for incrementing points. Our team uses - the - <a href="https://en.wikipedia.org/wiki/Fibonacci#Fibonacci_sequence" - >Fibonacci sequence of numbers</a - >. 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. - </p> - - <h2>How Much is Enough?</h2> - <p> - 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. - </p> - - <p> - 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. - </p> - - <ul> - <li> - 1 point: Small or basic text change. Updating configuration, fixing a - typo or cognitively simple bug. - </li> - <li> - 2 points: Task with light complexity. Some portions of code have to - change, be debugged, tested. - </li> - <li> - 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. - </li> - <li> - 5 points: Half a sprint's worth of more complicated work. Full-on - feature implementation for example. - </li> - </ul> - - <h2>Prioritizing Work</h2> - - <p> - 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! - </p> - - <p> - To communicate how "important" a task is, every story we have is - prioritized something like this: - </p> - <ol> - <li>Critical</li> - <li>Blocker</li> - <li>Highest</li> - <li>High</li> - <li>Medium</li> - <li>Low</li> - <li>Lowest</li> - </ol> - - <p> - 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". - </p> - - <h2>Sprint Planning/Backlog Refinement</h2> - - <p> - 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.

'/includes/head.php'); +?> + +<p class="description"> + 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. +</p> + +<h2>Points as a Measure of Work</h2> + +<p> + 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. +</p> + +<p> + Some teams have a special system for incrementing points. Our team uses + the + <a href="https://en.wikipedia.org/wiki/Fibonacci#Fibonacci_sequence">Fibonacci sequence of numbers</a>. 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. +</p> + +<h2>How Much is Enough?</h2> +<p> + 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. +</p> + +<p> + 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. +</p> + +<ul> + <li> + 1 point: Small or basic text change. Updating configuration, fixing a + typo or cognitively simple bug. + </li> + <li> + 2 points: Task with light complexity. Some portions of code have to + change, be debugged, tested. + </li> + <li> + 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. + </li> + <li> + 5 points: Half a sprint's worth of more complicated work. Full-on + feature implementation for example. + </li> +</ul> + +<h2>Prioritizing Work</h2> + +<p> + 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! +</p> + +<p> + To communicate how "important" a task is, every story we have is + prioritized something like this: +</p> +<ol> + <li>Critical</li> + <li>Blocker</li> + <li>Highest</li> + <li>High</li> + <li>Medium</li> + <li>Low</li> + <li>Lowest</li> +</ol> + +<p> + 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". +</p> + +<h2>Sprint Planning/Backlog Refinement</h2> + +<p> + 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. +</p> + +<h2>Tools to Get the Job Done</h2> + +<p> + Our team uses Jira at work, and I know some folks love it so much + they've paid for a personal license.

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.

Ideally - it also doesn't act like a piece of malware itself by making itself near - impossible to remove (looking at you, McAfee). - </p> - - <p> - 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 <em>all</em> potentially unwanted - programs, viruses, ransomware, and worms. An environment of trust should - be built around the programs that you want to run (read: - <em>allow to run</em>), 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? - </p> - - <p> - 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. - </p> - - <p> - 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 - <code>/bin</code> or <code>/usr/local/bin</code> 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. - </p> - - <p> - 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. - </p> - - <p> - * 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.

Ideally + it also doesn't act like a piece of malware itself by making itself near + impossible to remove (looking at you, McAfee). +</p> + +<p> + 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 <em>all</em> potentially unwanted + programs, viruses, ransomware, and worms. An environment of trust should + be built around the programs that you want to run (read: + <em>allow to run</em>), 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? +</p> + +<p> + 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. +</p> + +<p> + 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 + <code>/bin</code> or <code>/usr/local/bin</code> 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. +</p> + +<p> + 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. +</p> + +<p> + * 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. +</p> diff --git a/posts/2021-01-15-adam-s-2020-reading-list.html b/posts/2021-01-15-adam-s-2020-reading-list.html deleted file mode 100644 index 46f0fba..0000000 --- a/posts/2021-01-15-adam-s-2020-reading-list.html +++ /dev/null @@ -1,196 +0,0 @@ -<!DOCTYPE html> -<html lang="en"> - <head> - <link rel="stylesheet" href="/includes/stylesheet.css" /> - <meta charset="utf-8" /> - <meta name="viewport" content="width=device-width, initial-scale=1" /> - <meta - property="og:description" - content="The World Wide Web pages of Adam Carpenter" - /> - <meta - property="og:image" - content="https://nextcloud.53hor.net/index.php/s/Nx9e7iHbw4t99wo/preview" - /> - <meta property="og:site_name" content="53hor.net" /> - <meta property="og:title" content="Adam's 2020 Reading List" /> - <meta property="og:type" content="website" /> - <meta property="og:url" content="https://www.53hor.net" /> - <title>53hornet ➙ Adam's 2020 Reading List</title> - </head> - - <body> - <nav> - <ul> - <li> - <a href="/"> - <img alt="home" src="/includes/icons/home-roof.svg" /> - Home - </a> - </li> - <li> - <a href="/info.html"> - <img alt="information" src="/includes/icons/information-variant.svg" /> - Info - </a> - </li> - <li> - <a href="https://git.53hor.net"> - <img alt="git" src="/includes/icons/git.svg" /> - Repos - </a> - </li> - <li> - <a href="/software.html"> - <img alt="software" src="/includes/icons/floppy-variant.svg" /> - Software - </a> - </li> - <li> - <a type="application/rss+xml" href="/rss.xml"> - <img alt="rss" src="/includes/icons/rss.svg" /> - RSS - </a> - </li> - </ul> - </nav> - - <article> - <h1>Adam's <del>2020</del> <ins>Quarantine</ins> Reading List</h1> - - <ul> - <li> - Hammett, Dashiell. <em>The Maltese Falcon</em> - <p> - Excellent noir detective novel.

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. - </p> - - <p> - This did present some complications. First of all, - <code>bsdinstall</code> won't set this up for you automatically (and - sure enough, - <a - href="https://www.freebsd.org/doc/handbook/bsdinstall-partitioning.html" - >in the handbook</a - > - 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 - <code>bsdinstall</code> 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. - </p> - - <p> - 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. - </p> - - <p> - 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: - </p> - - <ul> - <li>Pool Type/Disks: mirror mfisyspd0 mfisyspd1</li> - <li>Pool Name: zroot</li> - <li>Partition Scheme: GPT (EFI)</li> - <li>Swap Size: 4g</li> - </ul> - - <p> - 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. - </p> - - <p> - The installer created the following disk layout for the two disks that I - selected. - </p> - - <pre> -<code> -atc@macon:~ % gpart show -=> 40 3907029088 mfisyspd0 GPT (1.8T) - 40 409600 1 efi (200M) - 409640 2008 - free - (1.0M) - 411648 8388608 2 freebsd-swap (4.0G) - 8800256 3898228736 3 freebsd-zfs (1.8T) - 3907028992 136 - free - (68K) - -=> 40 3907029088 mfisyspd1 GPT (1.8T) - 40 409600 1 efi (200M) - 409640 2008 - free - (1.0M) - 411648 8388608 2 freebsd-swap (4.0G) - 8800256 3898228736 3 freebsd-zfs (1.8T) - 3907028992 136 - free - (68K) -</code> -</pre> - - <p> - The installer also created the following ZPool from my single mirror - VDEV. - </p> - - <pre> -<code> -atc@macon:~ % zpool status - pool: zroot - state: ONLINE - scan: none requested -config: - - NAME STATE READ WRITE CKSUM - zroot ONLINE 0 0 0 - mirror-0 ONLINE 0 0 0 - mfisyspd0p3 ONLINE 0 0 0 - mfisyspd1p3 ONLINE 0 0 0 - -errors: No known data errors -</code> -</pre> - - <p> - There are a couple of things to take note of here. First of all, - <em>both</em> 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. - </p> - - <p> - So where do I go from here? I was tempted to just - <code>zpool add mirror ... ...</code> and just add my other disks to the - pool (actually, I <em>did</em> 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.

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. +</p> + +<p> + This did present some complications. First of all, + <code>bsdinstall</code> won't set this up for you automatically (and + sure enough, + <a href="https://www.freebsd.org/doc/handbook/bsdinstall-partitioning.html">in the handbook</a> + 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 + <code>bsdinstall</code> 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. +</p> + +<p> + 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. +</p> + +<p> + 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: +</p> + +<ul> + <li>Pool Type/Disks: mirror mfisyspd0 mfisyspd1</li> + <li>Pool Name: zroot</li> + <li>Partition Scheme: GPT (EFI)</li> + <li>Swap Size: 4g</li> +</ul> + +<p> + Everything else was left as a default. Then I followed the installer to + completion.

It's an easy way for her to keep + track of inventory, update photos of her products, and for people to + shop and search and sort and browse through it. This backend is an HTTP + service written in Rust. The frontend is a Vue.js app. I've used Vue and + JavaScript many times before but I recently ran into an incredibly + strange bug. One that I would have hoped JavaScript would have some + guard against. But JavaScript is an undefined language. +</p> + +<p> + I have a small component that uses a file input to collect an image from + the user. Then I append that file to a FormData and set that FormData as + a Fetch API request body. So I've got fetch API sending + multipart/form-data across the network to my backend. Awesome! The + backend is supposed to take each field of the request, turn the chunks + into a single stream of binary data, and write them out to an image. + Everything on the front seems like it's working great, it fires off the + request and throws no errors. But then the backend only sees a few bytes + of this multi-megabyte image. Not awesome! short chunks on the back-end. + The array of data in the API is less than ten bytes long, when this is a + many-kilobyte file I'm trying to upload. +</p> + +<p> + At this point I'm relentlessly debugging, trying to find out what's + wrong with the API. Why is it truncating the request down to a few + bytes, where's the rest of the data? It took me forever to actually + inspect what those few bytes are and, lo and behold they're ASCII for + <code>undefined</code> The request happily stringified an + <code>undefined</code> object, instead of maybe throwing a null + reference or undefined error during request creation because that's just + what JavaScript does. <em>The linter didn't even catch it.</em> +</p> + +<p> + You can see what the debugging logs looked like on the backend below. + Note that the <code>&data</code> is the field that spells out + "undefined".

Here's how I did it. - </p> - - <p> - If you've already set up TLS termination with HAProxy and - <code>certbot</code>, 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 <code>cat</code>-ing the chain and key together - like so: - </p> - - <pre> -<code> -cat /usr/local/etc/letsencrypt/live/$SITE/fullchain.pem /usr/local/etc/letsencrypt/live/$SITE/privkey.pem > /usr/local/etc/ssl/haproxy.pem -</code> - </pre> - - <p> - In this example, <code>$SITE</code> is your domain name that you fed - HAProxy when you created the certificate and <code>haproxy.pem</code> is - wherever you're storing HAProxy's combined certificate. Your HAProxy - config then points to that certificate like this: - </p> - - <pre> -<code> -macon% grep crt /usr/local/etc/haproxy.conf - bind *:443 ssl crt /usr/local/etc/ssl/haproxy.pem -</code> - </pre> - - <p> - 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 <code>certbot renew</code>, it detects which certificates - are present, and uses either the webroot or standlone server renewal - process. Then you have to <code>cat</code> the fullchain and privkey - together and restart HAProxy so it starts using the new certificate. - </p> - - <p> - To automate those steps, newer versions of - <code>certbot</code> will run any post renewal hooks (read: scripts) - that you want. You can also configure HAProxy and - <code>certbot</code> to perform the ACME challenge dance for renewal so - that you don't have to use it interactively. - </p> - - <p> - First, if you haven't already done it, change your HAProxy config so - there's a frontend+backend for responding to ACME challenges.
