Lessons from Writing a Compiler
The prototypical compilers textbook is: 600 pages on parsing theory. Three pages of type-checking a first-order type system like C. Zero pages on storing and checking the correctness of declarations (the “symbol table”). Zero pages on the compilation model, and efficiently implementing separate compilation. 450 pages on optimization and code generation. The standard academic literature is most use
Today we’re excited to announce the release of TypeScript 4.8! If you’re not yet familiar with TypeScript, it’s a language that builds on JavaScript and adds syntax for types. These types let you put your expectations and assumptions into your code, and those assumptions can then be checked by the TypeScript type-checker. This checking can help avoid typos, calling uninitialized values, mixing up
Onyx, a new programming language powered by WebAssemblyLearn about Onyx, a new imperative programming language that leverages WebAssembly and Wasmer for seamless cross-platform support What is Onyx?

This blog post hopes to convince you that Python is a compiled language. And by “Python”, I don’t mean alternate versions of Python like PyPy, Mypyc, Numba, Cinder, or even Python-like programming languages like Cython, Codon, Mojo1—I mean the regular Python: CPython! The Python that is probably installed on your computer right now. The Python that you got when you searched “python” on Google and

開発品質とDeveloper eXperienceを高めるコンテナ開発環境のご紹介 (Python) - ABEJA Tech Blog
はじめに こんにちは 2023年1月に入社し、システム開発グループでエンジニアをしてる春名です。 私の所属しているシステム開発グループでは、開発初期の環境構築をより効率的に行うための活動に取り組んでいます。 今回はそのうちの一つである、Pythonでコンテナ開発をする環境を構築した内容をご紹介します。 なぜコンテナ開発環境かと言いますと、単にAWSのECSやGoogle CloudのCloud Runを使ってデリバリーする案件が多いからです。 より使用頻度の高い開発環境を整備し、テンプレート化しておくことで開発の効率化に活用しています。 2025/12/19 追記 最新のPython開発環境を以下の記事でご紹介しています！ tech-blog.abeja.asia 本記事の内容もご参考にいただきつつ、最新の情報をご確認ください🚀 目次 はじめに 目次 今回作成する環境 Poetryによる
Over the course of my Spring 2020 semester at Harvey Mudd College, I developed a self-hosting compiler entirely from scratch. This article walks through many interesting parts of the project. It’s laid out so you can just read from beginning to end, but if you’re more interested in a particular topic, feel free to jump there. Or, take a look at the project on GitHub.

Bringing Python to Workers using Pyodide and WebAssembly
April 2, 2024Bringing Python to Workers using Pyodide and WebAssembly Starting today, in open beta, you can now write Cloudflare Workers in Python. This new support for Python is different from how Workers have historically supported languages beyond JavaScript — in this case, we have directly integrated a Python implementation into workerd, the open-source Workers runtime. All bindings, including
SemVer in Rust: Tooling, Breakage, and Edge Cases — FOSDEM 2024 Last month, I gave a talk titled "SemVer in Rust: Breakage, Tooling, and Edge Cases" at the FOSDEM 2024 conference. The talk is a practical look at what semantic versioning (SemVer) buys us, why SemVer goes wrong in practice, and how the cargo-semver-checks linter can help prevent the damage caused by SemVer breakage. TL;DR: SemVer is
Tier 4 Support § Support for these targets is entirely experimental. If this target is provided by LLVM, LLVM may have the target as an experimental target, which means that you need to use Zig-provided binaries for the target to be available, or build LLVM from source with special configure flags. zig targets will display the target if it is available. This target may be considered deprecated by

Boring Python: code quality
Boring Python: code quality December 19, 2022 Django, Python This is the second in a series of posts I intend to write about how to build, deploy, and manage Python applications in as boring a way as possible. In the first post in the series I gave a definition of what I mean by “boring”, and it’s worth revisiting: I don’t mean “reliable” or “bug-free” or “no incidents”. While there is some overla

Type hints are an essential part of modern Python. Type hints are the enabler for clever IDEs, they document the code, and even reduce unit testing needs. Most importantly, type hints make the code more robust and maintainable which are the attributes that every serious project should aim for. At Wolt we have witnessed the benefits of type hints, for example, in a web backend project which has 100

Making your own programming language is easier than you think (but also harder)
Making your own programming language is easier than you think (but also harder) In mid-December last year I started making my own programming language. It's waaay far from any production quality yet (though I did manage to write a working 1k LOC Monte-Carlo path tracer in it), but the project is on pause right now, so I figured it's a good time to write something about it. Disclaimer #1: I'm not a
