Today we’re excited to announce the release of TypeScript 5.2! If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by making it possible to declare and describe types. Writing types in our code allows us to explain intent and have other tools check our code to catch mistakes like typos, issues with null and undefined, and more. Types also power TypeScript’s edi
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. Table of contents What the pro
Let’s unpack why microservices often backfire early on, where they genuinely help, and how to structure your startup’s systems for speed and survival. Monoliths Are Not the EnemyIf you’re building some SaaS product, even a simple SQL database wrapper eventually may bring a lot of internal complexity in the way your business logic works; additionally, you can get to various integrations and backgro

Revenge of Lisp (Part 1⁄2) Background vector created by upklyak - www.freepik.com This may surprise you if you know me, but I’ve been learning Common Lisp for a few weeks now. It all started when I was reading, funnily enough, a blog post about another, much more hyped, language called Julia. The post was titled Julia and the reincarnation of Lisp, and in it the author lamented that despite his lo
The Alkyne GC · mcyoung
Alkyne is a scripting language I built a couple of years ago for generating configuration blobs. Its interpreter is a naive AST walker1 that uses ARC2 for memory management, so it’s pretty slow, and I’ve been gradually writing a new evaluation engine for it. This post isn’t about Alkyne itself, that’s for another day. For now, I’d like to write down some notes for the GC I wrote3 for it, and more

Notcurses
When Bison graced her village, it was Tuesday notcurses is a library for building complex, vibrant textual user interfaces (TUIs) on modern terminal emulators. It does not use Ncurses (though it does make use of libtinfo from that package), nor is it an X/Open Curses source-compatible replacement. It is written in C, with C++-safe headers. Rust, C++, and Python wrappers are available. Source and i
Lambda recently improved the cold start performance of container images by up to 15x, but this isn't the only reason you should use them. The tooling, ecosystem, and entire developer culture has moved to container images and you should too. January 2, 2024 Note: the second part of this post is available here. When AWS Lambda first introduced support for container-based functions, the initial react
Primitive Recursive Functions For A Working Programmer Aug 1, 2024 Programmers on the internet often use “Turing-completeness” terminology. Typically, not being Turing-complete is extolled as a virtue or even a requirement in specific domains. I claim that most such discussions are misinformed — that not being Turing complete doesn’t actually mean what folks want it to mean, and is instead a stand
The Atrocious State Of Binary Compatibility on Linux and How To Address It. By Dale Weiler GitHub Time To Read: ~30 Minutes Last Updated: Monday, March 17th 2025 Summary Linux binary compatibility is plagued by one thing that is often overlooked when evaluating shipping software on Linux. This article will deconstruct how to arrive to that conclusion, how to address it when shipping software today
Flatpak Is Not the Future
← ludocode.com Flatpak Is Not the Future Original date: 2021-11-18 Last updated: 2021-11-23 Deploying apps for the Linux desktop is hard. A major problem has historically been library compatibility. Different Linux distributions, and even different versions of the same distribution, have had incompatible libraries. Unfortunately, there hasn’t always been a culture of backwards compatibility on the
Lambda関数でTensorFlow Liteをインポートし、推論処理を実行する | DevelopersIO
はじめに 現在、カフェのシステムでは、機械学習を用いて、カメラを用いて動画を撮影し、商品の前にいる人物の骨格や手を検出することで、どのユーザがどの商品を取り出したかを判定しています。 今までは、骨格検出モデルを用いてエッジデバイスで動画を推論処理（撮影した画像から映っている人物の骨格の座標を検出する処理）を実行する、という構成で処理をしていました。今後、エッジ側のデバイスの費用を下げたり、骨格検出以外の処理を増やすことを考えているため、エッジデバイスからクラウドに動画を送信し、クラウド側で様々な処理を実行する、という構成を検討しています。 前回までの記事で、エッジデバイスでの動画処理（エンコード・送信）と、クラウド側の処理（動画の取り出し）について記載しました。 撮影した動画をリアルタイムにエンコードする方法【GStreamer】 【Kinesis Video Streams】Python
In short, the maximum possible speed is the same (+/- some nitpicks), but there can be significant differences in typical code, and it's hard to define what's a realistic typical example.The big one is multi-threading. In Rust, whether you use threads or not, all globals must be thread-safe, and the borrow checker requires memory access to be shared XOR mutable. When writing single-threaded code t
