This is based on a number of documents, beginning with OpenZFS Debian Bullseye Root on ZFS. There are some notable changes. View the original document and follow along:

One of my favorite features of modern filesystems is the sparse file, where "empty" portions of files are unallocated, so they don't consume any space. This allows oversubscription of disk blocks, so long as you never actually complete fill all of the files at once. But one common problem of sparse files is that they tend to grow, and there is often no way to solve this problem in place. But there is, with ZFS.

This site, my glorified blog, started out on Drupal 4. It wasn't until Drupal 8 that there was finally a single official way to handle putting media into nodes, with a media reference field and a media embed filter. Between then and now I used first the venerable img_assist and then the image_filter module, both of which fell by the wayside after D7. I replaced them both using php custom filters, but php in the database is now deprecated for security reasons.

If you want to "upgrade" a computer with a HDD to using a smaller disk, usually a SSD, you will need to come up with a way to shrink your windows partition. There are some for-pay software packages which do this for you, but no OSS tool which will do it with a simple click. There's a slightly meandering sequence of steps necessary to get everything working correctly. Your best allies are the gparted livecd, and a USB to SATA (probably) adapter to let you hook both disks up to your system at once. This process should work for basically any version of Windows from 2000 on, but I used it specifically with Windows 7.

Once upon a time, a Marvell developed a product called the Sheevaplug to drum up interest for their "Kirkwood" ARM-compatible CPU line. This was a complete linux system hidden in a wall wart, whose design they gave away as a reference. This led to a number of Sheevaplug-based devices hitting the market, including the PogoPlug, a line of cheap NAS devices which are all based on the Sheevaplug design with various single-core Marvell CPUs. They are now discontinuing not only that line but also the service for the same, so the devices are cheaper than ever before right now, and this is a great time to pick one up — I got one for $13.

My long-time faithful automotive companion, the 1982 300SD, is on its way out as a 1998 A8 Quattro comes in. It's just old enough (and low-spec enough) to have come with an ordinary radio instead of a LCD navigation unit. Unlike the 1997 which became the parts car when I got this car, the CD changer at least speaks an ordinary and boring protocol and it can be emulated away for those who would like a line input instead.

Assassins Creed is a really nifty psuedohistorical series of parcourt assassination games, and Assassins Creed: Unity is one of the recent entries in the series — which was included in a Humble Bundle of most of the titles. This post is not a news flash. It is a summary I'm writing because I don't want to have to track this information down again, distilled from a couple of pages I found googling.

Today I balanced the Dead Cat drone's motors with a zip tie and a hot glue gun. Wow, this is EASY. I got the idea by searching Youtube for motor balancing videos. For those too lazy to watch a video on the subject, you don't need one. Here's the steps to go through to balance your motors.

Quite some while ago, I bought an Audi A8 Quattro for what seemed like a good price. It was not a bad price, it just wasn't a good price after all. It's been a learning experience, which is automotive slang for I should have spent more money. I haven't become an expert by any means, but I've got a good overview of the vehicle, especially the engine. This is partly because I used Google to translate VAG1 SSP2 105, 161, and 162, which are "V8-Motor", "Audi A8", and "ABS 5 ... Audi A8" respectively, and partly because I've replaced both head gaskets. The following text is adapted from some text I wrote in response to an email question, which came in response to a post on QuattroWorld A8 forum. I thought it might be of interest to others thinking about doing a head job on the 32 valve Audi V8 Motor.

When you're putting together a so-called "Car PC", by which we usually mean a contemporary ATX-derivative computer installed into an automobile, you have a few hurdles to cross. The enclosure, interface, storage devices, and even the power management all become special problems. The power problems can largely be solved through the use of a Wide Input picoPSU, but what about systems outside of a 120W envelope, or systems where you need to switch more than the PC power? The answer is just one typical automotive relay.
