We’re rewriting the Angular compiler in Rust (partially)! Meet ngp (Angular Preprocessor): a hybrid compiler decoupling our transforms from TypeScript using Oxc, readying Angular for TypeScript 7 & native tooling. Read the deep dive: medium.com/@angularteam... 🛠️

It's easy to migrate C/C++ to Rust if all you care about is the file extension (and have sufficient budget for tokens). Our team spent the past few months figuring out strategies, infrastructure, and tools to migrate to **idiomatic** Rust for actually improved codebases. 1/🧵

Most recently they worked on a large-scale C-to-Rust migration (more details at lnkd.in/dS2c7Sb7) and have fresh, hands-on experience in C/Rust interop across module boundaries, build and test infrastructure (tests, Miri, fuzzing, differential testing), and AI software factories. 2/🧵

Building on that experience and appreciation for strong engineering culture, we now guide teams through adopting agentic engineering: mainmatter.com/services/age... Code still isn't free but if you can reduce its cost by 50%, that's massive enough to outpace your competitors. 3/3

@mainmatter.com's approach has always been to make writing the code the easy part of the SDLC (check out our playbook which is by now pretty outdated though: mainmatter.com/playbook/) based on solid infrastructure, tooling, processes, and automation. 2/🧵

Agentic engineering, software factories, etc. are a fascinating topic. Obviously there are footguns, inflated expectations, and opportunities to slowly dig your codebase's grave everywhere – but think of #ai what you want, there's plenty of opportunity as well. 1/🧵
