Debugging an ioctl Problem on OpenBSD
I was trying to use a V4L2 Ruby module for a project on my OpenBSD laptop but ran into a problem where sending the V4L2 ioctls from this module would fail, while other V4L2 programs on OpenBSD worked fine. ⌘ Read more

** What is an addressing mode? **
In a recent post I referenced addressing modes. But what the heck are they!?
The instruction register holds the program instruction that is currently being run.
A fixed number of bits within the instruction register represent the operation, e.g. “op. code” — examples of these instructions include things like add, subtract, load, and store. We can imagine the instruction register like this:

** A quick and dirty intro to the .pbm file format **
I’ve been fiddling with writing programs that draw pictures. I started with PostScript for this, but have since moved to writing programs that output in the .pbm format.
My goal here is to write noise to a .pbm file.
A .pbm file is the lowest common denominator among image file formats.
An example of the format,

I feel like it took me a bit longer to fully understand how to work in Smalltalk than it did most languages. The IDE is different than anything I’ve used before, and probably anything you’ve seen as well. You’re not going to be opening myscript.st in your favorite text editor, and then run it from the command line as you would a Python program. It takes a little mental adjustment to start with.

Day 16 of Advent of Code is so confusing that I will not finish today’s puzzle. I wonder if yesterday was my last day with Advent of Code, or will the puzzles become more understandable and easier again in the next few days? Maybe I’m just more the practical type. I like programming, but such complex algorithms are not really my thing. And in the end, Advent of Code is supposed to be fun… ⌘ Read more
WSL 2 GPU Support for Docker Desktop on NVIDIA GPUs

Struct Tags with Underscore Before Function Names
In the Go world, an underscore (_) before an expression is called a blank identifier. As you may already know, identifiers—user-defined program components, e.g., name of a function, variable, or package—in Go must be preceded by an underscore or a letter (a-z or A-Z). If they aren’t, you’ll receive the compile- time error which essentially means Go cannot read the syntax of your code (you didn’t write your code correctly … ⌘ Read more
