The RAM shortage comes for us all
Memory price inflation comes for us all, and if you're not affected yet, just wait. I was building a new PC last month using some parts I had bought earlier this year. The 64 Gigabyte T-Create DDR5 memory kit I used cost $209 then. Today? The same kit costs $650! Just in the past week, we found out Raspberry Pi's…

The web runs on tolerance
If you've ever tried to write a computer program, you'll know the dread of a syntax error. An errant space and your code won't compile. Miss a semi-colon and the world collapses. Don't close your brackets and watch how the computer recoils in distress. The modern web isn't like that. You can make your HTML as…

Booting Linux in QEMU and Writing PID 1 in Go to Illustrate Kernel as Program
Most books and courses introduce Linux through shell commands, leaving the kernel as a mysterious black box doing magic behind the scenes. In this post, we will run some experiments to demystify it: the Linux kernel is just a binary that you can build and run.

Transparent leadership beats servant leadership
I spent a couple of years managing a team, and I entered that role – like many – without knowing anything about how to do it. I tried to figure out how to be a good manager, and doing so I ended up reading a lot about servant leadership . It never quite sat right with me, though. Servant leadership seems to me a lot…

Why WinQuake exists and how it works
When I took a look at the history of Quake binaries, they all made sense to me. quake.exe was the original release, able to run on DOS and Windows 95. Then came vquake.exe to support the hardware accelerated chip Vérité 1000. Later, glquake.exe generalized hardware acceleration to any vendor providing OpenGL drivers…

Why doesn't Apple make a standalone Touch ID?
I finally upgraded to a mechanical keyboard. But because Apple's so protective of their Touch ID hardware, there aren't any mechanical keyboards with that feature built in. But there is a way to hack it. It's incredibly wasteful, and takes a bit more patience than I think most people have, but you basically take an…

8086 Microcode Browser
Since releasing 486Tang , I’ve been working on recreating the 8086 with a design that stays as faithful as possible to the original chip. That exploration naturally led me deep into the original 8086 microcode — extracted and disassembled by Andrew Jenner in 2020.
