Curl is just the hobby

Let's create a Tree-sitter grammar
One of my favorite features in Neovim is the Tree-sitter integration. It allows for fast syntax highlighting that works well even in an error state (often the case when you’re editing code), and it has additional semantics (you can differentiate between function parameters and local variables).

Deep Bug
The project has been haunted by a mysterious bug since sometime February. It relates to the code that constructs the index, particularly the code that merges partial indices. In short the search engine constucts the reverse index through successive merging of smaller indices, which reduces the overall memory…

C23: A Slightly Better C
One of the established and most popular programming languages is the C programming language. It is relatively easy to learn, and highly practical. Maybe surprisingly, the C programming language keeps evolving, slowly and carefully. If you have GCC 13 or LLVM (Clang) 16, you already have a compiler with some of the…

Fractional scales, fonts and hinting
GTK 4.14 will be released very soon, with new renderers that were introduced earlier this year. The new renderers have much improved support for fractional scaling—on my system, I now use 125% scaling instead of the 'Large Text' setting, and I find that works fine for my needs. Magical numbers Ever since 4.0, GTK…

Sonic Pi: Ruby as a Composition Tool
Like the blip of an intro on the front page says, my degree was originally in music. My running joke as a web dev is that neither has meaningfully required me to count past 32. And while my main concentration was vocals, I've since realized I should probably stop strictly calling this a nontechnical field, because my…

Optimizing Ruby's JSON, Part 4
In the previous post, we established that as long as ruby/json wasn’t competitive on micro-benchmarks, public perception wouldn’t change. Since what made ruby/json appear so bad on micro-benchmarks was its setup cost, we had to find ways to reduce it further.

Async Rust is not safe with io_uring
The demo shows that even though the behavior appears similar, TCP connections leak when using the io_uring driver but not with the epoll driver. I've also tested this across various io_uring runtimes, and it turns out to be a common issue across all of them.
