Fish 4.0: The Fish Of Theseus
About two years ago, our head maintainer @ridiculousfish opened what quickly became our most-read pull request: #9512 - Rewrite it in Rust Truth be told, we did not quite expect that to be as popular as it was. It was written as a bit of an in-joke for the fish developers first, and not really as a press release to be shared far and wide. We didn’t post it anywhere, but other people did, and we go

One thing I particularly liked about this vehicle was the In-V
January 30, 2023 In this post, we'll implement a GPT from scratch in just 60 lines of numpy. We'll then load the trained GPT-2 model weights released by OpenAI into our implementation and generate some text. Note: This post assumes familiarity with Python, NumPy, and some basic experience with neural networks. This implementation is for educational purposes, so it's missing lots of features/improv
I’ve been meaning to write a post about my perspective on Open Source and corporate entities. I already got the rough outline of it; however, I’m suffering from writer’s block, but more importantly, the whole post is a praise of how Shopify engages with Open Source communities. Hence, given the current climate, I don’t think I could publish it without addressing the elephant in the room first anyw
Introducing Amazon MemoryDB for Redis – A Redis-Compatible, Durable, In-Memory Database Service | Amazon Web Services
AWS News Blog Introducing Amazon MemoryDB for Redis – A Redis-Compatible, Durable, In-Memory Database Service Interactive applications need to process requests and respond very quickly, and this requirement extends to all the components of their architecture.

Most of my readers are probably familiar with procedural programming, object-oriented programming (OOP), and functional programming (FP). The majority of top programming languages on all of the language popularity charts (like TIOBE) support all three to some extent. Even if a programmer avoided one or more of those three paradigms like the plague, they’re likely at least aware of them and what th
Show navigation A recent article on WebAssembly Garbage Collection (WasmGC) explains at a high level how the Garbage Collection (GC) proposal aims to better support GC languages in Wasm, which is very important given their popularity. In this article, we will get into the technical details of how GC languages such as Java, Kotlin, Dart, Python, and C# can be ported to Wasm. There are in fact two m

Patterns for Building LLM-based Systems & Products [ llm engineering production 🔥 ] · 66 min read Discussions on HackerNews, Twitter, and LinkedIn “There is a large class of problems that are easy to imagine and build demos for, but extremely hard to make products out of. For example, self-driving: It’s easy to demo a car self-driving around a block, but making it into a product takes a decade.”
A Walk with LuaJIT
The following is a chronicle of implementing a general purpose zero-instrumentation BPF based profiler for LuaJIT. Some assumptions are made about what this entails and it may be helpful to read some of our other work in this area. One major change from prior efforts is that instead of working with the original Parca unwinder we are now working with the OpenTelemetry eBPF profiler. If you missed t
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.

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
I want to write a post about Pitchfork, explaining where it comes from, why it is like it is, and how I see its future. But before I can get to that, I think I need to share my mental model on a few things, in this case, Ruby’s GVL. For quite a long time, it has been said that Rails applications are mostly IO-bound, hence Ruby’s GVL isn’t that big of a deal and that has influenced the design of so

This paper reflects work done in late 2022 and 2023 to audit for vulnerabilities in terminal emulators, with a focus on open source software. The results of this work were 10 CVEs against terminal emulators that could result in Remote Code Execution (RCE), in addition various other bugs and hardening opportunities were found. The exact context and severity of these vulnerabilities varied, but some
My thoughts on writing a Minecraft server from scratch (in Bash) For the past year or so, I've been thinking about writing a Minecraft server in Bash as a thought excercise. I once tried that before with the Classic protocol (the one from 2009), but I quickly realized there wasn't really a way to properly parse binary data in bash. Take the following code sample: function a() { read -n 2 uwu echo

Useful VS Code Extensions For Front-End Developers — Smashing Magazine
Meet useful Visual Studio Code extensions for web developers: little helpers to minimize slow-downs and frustrations, and boost developer’s workflow along the way. Recently, we’ve also covered CSS auditing tools, CSS generators and accessible front-end components — you might find them useful, too. In this post, we look into useful VS Code extensions for front-end development, from fine productivit
In my previous post, I wrote about system fonts and their advantages over web fonts. I encouraged a ‘system fonts first’ approach, arguing that, compared to system fonts, web fonts (a) can negatively impact performance, (b) use more data, and (c) increase your site’s energy consumption. But a web without web fonts would be a far less interesting one — maybe by using web fonts a little more respons
Python behind the scenes #13: the GIL and its effects on Python multithreading
As you probably know, the GIL stands for the Global Interpreter Lock, and its job is to make the CPython interpreter thread-safe. The GIL allows only one OS thread to execute Python bytecode at any given time, and the consequence of this is that it's not possible to speed up CPU-intensive Python code by distributing the work among multiple threads. This is, however, not the only negative effect of
This year’s Advent of Code has been brutal (compare the stats of 2023 with that of 2022, especially day 1 part 1 vs. day 1 part 2). It included a problem to solve with dynamic programming as soon as day 12, which discouraged some people I know. This specific problem was particularly gnarly for Advent of Code, with multiple special cases to take into account, making it basically intractable if you

Last year I finally decided to learn some Rust. The official book by Steve Klabnik and Carol Nichols is excellent, but even after reading it and working on some small code exercises, I felt that I needed more to really understand the language. I wanted to work on a small project to get some hands-on experience, but most of my ideas didn’t feel very well suited for Rust. Then I started reading the
If you are a Rubyist, you’ve likely been writing # frozen_string_literal: true at the top of most of your Ruby source code files, or at the very least, that you’ve seen it in some other projects. Based on informal discussions at conferences and online, it seems that what this magic comment really is about is not always well understood, so I figured it would be worth talking about why it’s there, w
GIMP 2.99.12 is a huge milestone towards GIMP 3.0. Many of the missing pieces are getting together, even though it is still a work in progress.

Introduction Some part of me has always been fascinated with coercing code to run in weird places. I scratch this itch a lot with my security research projects. These often lead me to writing shellcode to run in kernels or embedded hardware, sometimes with the only way being through an existing bug. For those not familiar, shellcode is honestly hard to describe. I don’t know if there’s a very form
Let’s Write a Tree-Sitter Major Mode Creating a standard programming major mode presents significant challenges, with the intricate tasks of establishing proper indentation and font highlighting being among the two hardest things to get right.
