All I want for Christmas is these seven TypeScript improvements
It's Christmastime and I've been happily working through this year's Advent of Code in Deno (look forward to a blog post in the new year). What with all the presents, it's a good time to think about what we'd most like to see from TypeScript in the new year. Here are my top seven feature requests for 2023. Yes, that's…

Win16 Retro Development
Several months ago I had a go at producing a high resolution 256-color driver for Windows 3.1. The effort was successful but is not yet complete. Along the way I re-learned many things I had forgotten, and learned several new ones. This blog entry is based on notes I made during development.

For Want of a JOIN
Once upon a time, I was on a small team tasked with building a data pipeline. On this team was someone we’ll call Bob, who was fresh out of grad school and hadn’t had much experience with software engineering, and no experience with SQL. As part of this data pipeline, Bob had to combine the data from two tables. JOIN…

Avoid exception throwing in performance-sensitive code
There are various ways in software to handle error conditions. In C or Go, one returns error code. Other programming languages like C++ or Java prefer to throw exceptions. One benefit of using exceptions is that it keeps your code mostly clean since the error-handling code is often separate. It is debatable whether…

Programming as Play
I often want to program something just for fun without any expectations. But why? Well, a recent scientific paper investigated this idea of programming as play.

This year in LLVM
Towards the end of last year, I switched from working on PHP at JetBrains, to working on LLVM at Red Hat. While it was already under discussion beforehand, this catalyzed the creation of the PHP foundation , which now pays multiple people to work on PHP. Special thanks for this go to Roman Pronskiy, who did most of…

Implementing ‘strlen’ using SVE
In C, the length of a string in marked by a 0 byte at the end of the string. Thus to determine the length of the string, one must scan it, looking for the 0 byte. Recent ARM processors have a powerful instruction set (SVE) that is well suited for such problems. It allows you … Continue reading Implementing ‘strlen’…

GCC now includes Modula-2 and Rust. Do they work on OpenBSD?
Two new language frontends have been added to GCC : Modula-2 and Rust . I think this is great news on both accounts: having a Wirth language in GCC fills my childhood heart with joy (though I do wish GNU Pascal can one day be revived and mainlined, as Pascal was the first non- BASIC language I learned). And Rust…

A few new things in Emacs 29
Everybody with an Emacs blogs raves about Emacs 29 these days. Things like Eglot, tree-sitter, SQL support and the like. Well, this is all nice – more than nice, brilliant! – but let’s not forget a few minor advances which are coming with Emacs 29. Let me mention a few things that I especially like.

Quite OK Image is now my favorite asset format
The Quite OK Image (QOI) format was announced late last year and finalized into a specification a month later. Initially dismissive, a revisit has shifted my opinion to impressed. The format hits a sweet spot in the trade-off space between complexity, speed, and compression ratio. Also considering its alpha channel…

A Linux Evening
I love to have Linux as my main OS. For someone who spends most of his time programming, writing HTML, writing LaTeX, and browsing the net, it is nearly a perfect tool. Packages are one "apt install" away. Mounting my website is one sshfs away and with private key authentication I don't even have to type my password…

IDN is crazy
IDN, International Domain Names, is the concept that lets us register and use international characters in domain names, and by international we of course mean characters outside of the ASCII range. Recently I have fought some battles against IDN and IDN decoding so I felt this urge to write a lot of words about it ……
