Omarchy development practices lead to predictable security issues

I don't want to learn your query language (2018)
This is a bit of a rant but I really don't like software that invents its own query language. There's a trillion different ORMs out there. Another trillion databases with their own query language. Another trillion SaaS products where the only way to query is to learn some random query DSL they made up.

I spent a year making an ASN.1 compiler in D
In this post I’ll just rambling about ASN.1; parts of the compiler implementation, and some of the tool’s output rather than the tool itself as its still too WIP to really advertise on its own yet.

Toward a better programming
When I built the original prototype of Light Table I didn’t have any grand purpose or goal in mind. I simply had some ideas on how programming could be better and I wanted to see how hard they would be to build. Until fairly recently, it never dawned on me that I’ve actually spent the past decade trying out ideas on…

Concurrency I can finally understand and write correctly
I wrote my Advent of Code in D. The programming language. It was the first time I used D in earnest every day for something substantial. It was fun and I learned things along the way, such as easy metaprogramming, concurrency I could write correctly, and functional programming that doesn’t feel like I have one arm…

The repo author, @BenjDicken, created a fun visualization of each language’s performance. Here’s one of the visualizations, which shows Ruby as the third slowest…

State Machines in Rust
Every now and then I like to think about topics that don't directly relate to my daily work. One of those topics has been parsers: back in January I wrote about byte-ordered stream parsing and how I think we can improve streaming parsing in Rust with a small set of API additions.
