When str.lower() is a security vulnerability in Python
Some internet standards only support ASCII characters, but the world uses much more than the Latin alphabet. Thus, a mapping from Unicode to ASCII for use in domain names is required. NamePrep was...

LLMs as the new high level language

I hate compilers
You'd think that given the same bytes of input you'd get the same bytes of output. lol. lmao. No, you don't. It's complicated.

Writing a Demoscene Intro for the ZX Spectrum
In the late 80s, I spent an embarrassing number of hours hunched over my ZX Spectrum, typing in Sinclair BASIC programs and rudimentary assembler routines copied from magazines, trying to re-create the Amiga crack intros I’d seen round at a friend’s house. Obviously, they never came even slightly close - but now, many…

An idiot’s guide to lead optimisation for proteins
Lead optimisation is the step in drug design where you take a molecule that sort of works and try to make it actually work, and it’s arguably the step where most real-world design campaigns succeed or die. Due to the influence of a couple of my pals , I have recently become interested in using machine learning to do…

I hate: Programming Wayland applications
If you want to program a graphical application for linux, your primary choices are using either X11 or Wayland. According to Wikipedia, X11 had its first release in 1984. X11 follows a client-server-model. I assume it's because the whole computational environment, was very different back then. If you have a central…

Bun 1.4 Rust rewrite is not looking good?
I care about Bun. I have been rooting for it since the initial release in 2022. I switched all my development from Node to Bun. I used it in the development of the Nue framework and now with my new project Hertta .

The GitHub wiki is an anti-pattern (2022)
Using the wiki on GitHub makes life more difficult for your users, and you as a maintainer. Use the `/docs` folder and GitHub Pages instead and keep your docs in sync with code

C extensions, portability, and alternative compilers
Anyone who's written C knows that full ISO C standard-adhering code is an impractical rarity. Most real world C code out there relies on non-standard behaviors and language extensions to varying extents, and a lot of this isn't for extra features, but just to work around bugs and gaps in different compilers and…

Pyodide 314.0: Python packages can now publish WebAssembly wheels to PyPI
We are pleased to announce the Pyodide 314.0 release. This release focuses on standardization and packaging, marking a significant milestone in the Python-in-the-browser ecosystem. PEP 783 is Accepted: What Does It Mean? The acceptance of PEP 783: Emscripten packaging marks perhaps the most exciting change in the…

Are LLM merge rates not getting better?
I was reading the metr article on how llm code passes test much more often than it is of mergeable quality . They look at the performance of llm s doing programming when the success criterion is “passes all tests” and compare it to when the success criterion is “would get approved by the maintainer”. Unsurprisingly…

C++26: Trivial infinite loops are no longer undefined behaviour
Let’s start with a question! Is this program well-defined? 1 2 3 4 int main() { while (true) ; } If you said yes, you’d be wrong — at least before C++26. A while (true); loop with no side effects used to be undefined behaviour. Compilers were free to assume it terminates, and some — Clang in particular — would…

Protobuf has LSP support
Buf is proud to announce the first fully-featured, spec-compliant LSP server for Protobuf. The Language Server Protocol is the standard API for integrating language support into your favorite IDE or text editor, such as VSCode, IntelliJ, or Neovim. An LSP server provides the smarts that power go to definition, code…
