I 10x'd a TI-84 emulator's speed by replacing a switch-case
There’s a javascript emulator for the TI83+, TI84+, and TI84+CSE calculators called jsTIfied, which was written by Christopher Mitchell, founder of the calculator fan site cemetech.net. There’s not a whole lot of reasons to use it over something else if you’ve got a native option available, but if you don’t it’s…

Debugging bare-metal STM32 from the seventh level of hell
Here’s a not-so-brief story about troubleshooting a problem that was at times vexing, impossible, incredibly challenging, frustrating, and all around just a terrible time with the bare-metal STM32G4 firmware for the moteus brushless motor controller. Background First, some things for context: moteus has a variety of…

Please Use ZFS with ECC Memory (2014)
In this blogpost I argue why it's strongly recommended to use ZFS with ECC memory when building a NAS. I would argue that if you do not use ECC memory, it's reasonable to also forgo on ZFS altogether and use any (legacy) file system that suits your needs.

Technical reasons to choose FreeBSD over GNU/Linux (2020)
I run FreeBSD as my daily driver on both my main workstation and on all my servers and I have been running FreeBSD since about 1999 because I consider it an amazing operating system. In this article I will address some of the technical reasons for choosing FreeBSD over a GNU/Linux distribution.

Faster CRC32-C on x86
Computing the CRC-32C of a 4KB buffer on a modern x86 chip can be done as a simple loop around the crc32 instruction:

Kubernetes reinvented virtual machines in a good sense
How Virtual Machines were used to deploy services. What old problems containers solve and what new problems create. How Kubernetes used containers to recreate Virtual Machines in a better way?

Cloud Computing Without Containers: Hello Isolates
We have a cloud computing platform called Workers. Unlike essentially every other cloud computing platform I know of, it doesn’t use containers or virtual machines. We believe that is the future of Serverless and cloud computing in general, and I’ll try to convince you why.

Build Unix, Not Uber
I spent the last three weeks in Seoul, partly visiting family I hadn’t seen in years and partly taking a vacation from my usual work in my usual city in my usual context of life. While I haven’t been able to work much at all, I spent my subway rides and waiting-in-line times reading the Singularity Sky series of…

Why the Windows Registry sucks technically (2010)

Understanding modern Linux routing (and wg-quick)
Back in the old days, I could just type route (or, later, ip route) in my Linux terminal and get an accurate picture of all my routes. This is no longer the case.

Building a fast all-SSD NAS on a budget
I edit videos non-stop nowadays. In a former life, I had a 2 TB backup volume and that stored my entire digital life—all my photos, family video clips, and every bit of code and text I'd ever written. Video is a different beast, entirely. Every minute of 4K ProRes LT footage (which is a very lightweight format…

Yes, the 8086 wanted to be mechanically translatable from the 8080, but
So many addressing modes, so little space.
