It’s been just over two years since I started learning Rust. Since then, I’ve used it heavily at my day job, including work in the Firecracker code base, and a number of other projects. Rust is a great fit for the systems-level work I’ve been doing over the last few years: often performance- and density-sensitive…
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
Haiku uses a custom vector image format to store icons. This is surprising both because most OSes consider bitmaps to be totally sufficient to represent icons and because there are plenty of vector graphics formats out this (e.g. SVG). The goal of the Haiku Vector Icon Format (HVIF) is to make vector icon files as…
A practical guide to creating and maintaining powerful megamerge workflows in Jujutsu for faster, conflict-free development.

Several months ago, PHP officially announced the end-of-life forPHP5.
OpenClaw became the fastest-growing repo in GitHub history almost overnight. The PR data offers a preview of what the future of open source contribution may look like.
When I ask people at trendy big tech companies why algorithms quizzes are mandatory, the most common answer I get is something like "we have so much scale, we can't afford to have someone accidentally write an O(n^2) algorithm and bring the site down" 1 . One thing I find funny about this is, even though a decent…
Postgres 16 introduces quite a few improvements to the query planner and makes many SQL queries run faster than they did on previous versions of PostgreSQL. This post is a deep dive into 10 of the improvements, including code blocks and comparisons of query plan output between Postgres 15 & Postgres 16.
Wrong estimates aren’t your fault, but they are definitely your problem
Some time ago I mentioned that we went through the curl source code and eventually got rid of all strncpy() calls. strncpy() is a weird function with a crappy API. It might not null terminate the destination and it pads the target buffer with zeroes. Quite frankly, most code bases are probably better off completely ……
About LPython is a Python compiler that can compile type-annotated Python code to optimized machine code. LPython offers several backends such as LLVM, C, C++, WASM, Julia and x86. LPython features quick compilation and runtime performance, as we show in the benchmarks in this blog. LPython also offers Just-In-Time…
Musings on navigating the tech bubble with philosophy and self-improvement.
In this post I want to create a single file C file program to open a windows inside Linux without using xlib or any similar libraries. The idea is to explore X11 protocol and see how it is used to interact with X server to create windows.
Making music with low-level C code, from a simple saw wave to playing melodies
I’ve been learning Persian (Farsi) for a while now, and I’m using a bunch of tools for it. The central one is certainly Anki, a spaced repetition app to train memory. I’m creating my own never-ending deck of cards, with different types of content, for different purposes. The most frequent type of cards is grammar…
In my never ending quest to have oksh support every C compiler in existence, I have ported two more C compilers to OpenBSD . They are chibicc and kefir. As always, let's review them and at the end I'll have links to unofficial ports so that you can play around with these C compilers.
Since July 2005, when Django was open-sourced , Jacob Kaplan-Moss and I have been the two Benevolent Dictators For Life (BDFLs) of the project. Today we’re both retiring from our formal BDFL roles, given that (1) we don’t have the time for it that we once had and (2) Django is in great shape with a vibrant community…

First, ClojureScript now ships with greatly enhanced support for integration with popular JavaScript bundling tools such as…
