I got robbed of my first kernel contribution
Context Around a year and a half ago, I’ve asked my former company for some time to work on an issue that was impacting the debugging capabilities in our project: gdbserver couldn’t debug multithreaded applications running on a PowerPC32 architecture. The connection to the gdbserver was broken and it couldn’t control…

Writing a debugger from scratch: Breakpoints
(New to this series? Consider starting from part 1) At the end of the last post, we started to get some interesting functionality with the ability to resolve addresses to names in a module.

Arena allocator tips and tricks
Over the past year I’ve refined my approach to arena allocation . With practice, it’s effective, simple, and fast; typically as easy to use as garbage collection but without the costs.

The State of Async Rust: Runtimes

Choose Postgres queue technology
Introduction Postgres queue tech is a thing of beauty, but far from mainstream. Its relative obscurity is partially attributable to the cargo cult of “scale”. The scalability cult has decreed that there are several queue technologies with greater “scalability” than Postgres, and for that reason alone, Postgres isn’t…

Unpacking Elixir: Resilience
The nine nines. 99.9999999% of uptime. Whether the AXD301 actually deserves to be held up as a system of nine nines seems debatable. I am not particularly interested in that debate. Erlang has a strong record for reliability and a design intended to help you as a developer and operator achieve your nines. Maybe just…

Fiber, a less known concept compared with coroutine, is a pretty powerful addition to cooperative multitasking. As a graphics programmer in game industry, I totally appreciate the great flexibility that fiber brings on the table.

Parsing integers quickly with AVX-512
If I give a programmer a string such as "9223372036854775808" and I ask them to convert it to an integer, they might do the following in C++: std::string s = .... uint64_t val; auto [ptr, ec] = std::from_chars(s.data(), s.data() + s.size(), val); if (ec != std::errc()) {} // I have an error ! // val … Continue reading…

Java 21: The Nice, the Meh, and the Momentous
When Java 17 was released in 2021 as a “long term support” version, I wrote an article dissecting its features and came to the conclusion that it had a few nice features, but none that were compelling reasons to upgrade. Except one: tens of thousands of bug fixes.

Speeding up the JavaScript ecosystem – Polyfills gone rogue
Many popular npm packages depend on 6-8x more packages than they need to. Most of these are unnecessary polyfills and it's one of the key reasons node_modules folders are so large. The eslint ecosystem seems to be most affected by this.

Most UI applications are broken real-time applications
I’ve been programming for a long time. When I say long time, I mean decades, with an S. Hopefully that’s long enough. In that time my experience has primarily been programming for contemporary platforms, e.g. Linux, Windows, macOS on desktop-class or server-class CPU architectures. Recently, I embarked on building a…

Why Kakoune
Recently I’ve stumbled upon a video about Kakoune, a code editor: Idiot user tries to use Kakoune (for notes? Also Helix?). Funnily enough, I was mentioned in this video, which was a surprise, and made me laugh for quite a while: Let’s go back to the official plugins page.
