Rust to C compiler – 95.9% test pass rate, odd platforms (fractalfir.github.io)
This is an update on the progress I have made on my Rust to C compiler. I am experimenting a bit with a new article format: instead of an overarching theme, this is more of a collection of smaller bits and pieces, sewn together.

An Oracle engineer has posted a set of patches implementing an ALGOL 68 programming language front-end for the GNU Compiler Collection (GCC). These are work-in-progress patches for the half century old niche programming language.

A basic introduction to the classfile API in Java (ifesunmola.com)
JEP 484 defines the class file API as a standard way for parsing, generating, and transforming Java class files. You’ll never need to use it if you don’t write/never plan to write a JVM-based library, framework or compiler. ASM would still be the go-to library for most developers because there’s already a lot of information about it online. As of the time of writing, the API is still in preview and will be finalized with the release of JDK 24.
