What happens if you remove randomness from Doom?
For some reason, recently I have been thinking about Doom. This evening I was wanting to explore some behaviour in an old version of Doom and to do so, I hex-edited the binary and replaced the random number lookup table with static values.

How the .NET Foundation kerfuffle became a brouhaha
After I wrote most of this blog post the night of October, 5th 2021 I wasn't sure I would post it. After the events of the last 36 hours, I felt I needed to capture my experience on my website where it can only be edited by me. After reading this, I hope you will have a clear set of datapoints from my point of view…

I'm sorry, but you still have to think
DHH, the creator of the Ruby on Rails framework, decided to rewrite Campfire Once from Ruby on Rails to Rust. Or rather ask a clanker to do it for him, as he can't stand reading or writing the Rust code himself. After that he added rewrites in other languages , like Elixir and Go.

Dijkstra On the foolishness of "natural language programming"
Since the early days of automatic computing we have had people that have felt it as a shortcoming that programming required the care and accuracy that is characteristic for the use of any formal symbolism. They blamed the mechanical slave for its strict obedience with which it carried out its given instructions, even…

Uncertain<T>
GPS coordinates aren’t exact. Sensor readings have noise. User behavior is probabilistic. Yet we write code that pretends uncertainty doesn’t exist, forcing messy real-world data through clean Boolean logic.

Why F#?
If someone had told me a few months ago I’d be playing with .NET again after a 15+ years hiatus I probably would have laughed at this.1 Early on in my career I played with .NET and Java, and even though .NET had done some things better than Java (as it had the opportunity to learn from some early Java mistakes), I…

The fish shell is amazing
I’ve been lurking the fish shell for a couple of years now (and the nushell but it is another story for another time). Not so long ago, I decided to try it, and it’s simply… amazing. If I had to state one feature that makes me like to use it, it’ll be the autocompletion, hands down. It’s the first time I just take a…

When does MCP make sense vs CLI?
I’m going to make a bold claim: MCP is already dying. We may not fully realize it yet, but the signs are there. OpenClaw doesn’t support it. Pi doesn’t support it. And for good reason.

Piet: Programming language in which programs look like abstract paintings (2002)
Piet is a programming language in which programs look like abstract paintings. The language is named after Piet Mondrian , who pioneered the field of geometric abstract art. I would have liked to call the language Mondrian, but someone beat me to it with a rather mundane-looking scripting language. Oh well, we can't…

Gentle introduction to GPUs inner workings
This article summarizes some lower level aspect of how GPU executes. Although GPU programming is not that complicated when compared to CPU, it also doesn’t match to what hardware is doing exactly. The reason is that we can’t just program GPU without some API, which is an abstraction over its inner workings. Since few…
