Docker is deleting Open Source organisations - what you need to know
Coming up with a title that explains the full story here was difficult, so I'm going to try to explain quickly. Yesterday, Docker sent an email to any Docker Hub user who had created an "organisation", telling them their account will be deleted including all images, if they do not upgrade to a paid team plan. The email contained a link to a tersely written PDF (since, silently edited) which was mi

REST API Design Best Practices Handbook – How to Build a REST API with JavaScript, Node.js, and Express.js
By Jean-Marc Möckel I've created and consumed many API's over the past few years. During that time, I've come across good and bad practices and have experienced nasty situations when consuming and building API's. But there also have been great moments. There are helpful articles online which present many best practices, but many of them lack some practicality in my opinion. Knowing the theory with
I joined GitLab in October 2015, and left in December 2021 after working there for a little more than six years. While I previously wrote about leaving GitLab to work on Inko, I never discussed what it was like working for GitLab between 2015 and 2021. There are two reasons for this: I was suffering from burnout, and didn't have the energy to revisit the last six years of my life (at that time)I w
Developers are increasingly relying on AI coding assistants to accelerate our daily workflows. These tools can autocomplete functions, suggest bug fixes, and even generate entire modules or MVPs. Yet, as many of us have learned, the quality of the AI’s output depends largely on the quality of the prompt you provide. In other words, prompt engineering has become an essential skill.

Making JavaScript run fast on WebAssembly - Bytecode Alliance
JavaScript in the browser runs many times faster than it did two decades ago. And that happened because the browser vendors spent that time working on intensive performance optimizations. Today, we’re starting work on optimizing JavaScript performance for entirely different environments, where different rules apply. And this is possible because of WebAssembly. We should be clear here—if you’re run
Introducing Distance Correlation, a Superior Correlation Metric. | Towards Data Science

PyTorch and TensorFlow are far and away the two most popular Deep Learning frameworks today. The debate over which framework is superior is a longstanding point of contentious debate, with each camp having its share of fervent supporters. Both PyTorch and TensorFlow have developed so quickly over their relatively short lifetimes that the debate landscape is ever-evolving. Outdated or incomplete in
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
Spec-driven development with AI: Get started with a new open source toolkit
As coding agents have grown more powerful, a pattern has emerged: you describe your goal, get a block of code back, and often… it looks right, but doesn’t quite work. This “vibe-coding” approach can be great for quick prototypes, but less reliable when building serious, mission-critical applications or working with existing codebases. Sometimes the code doesn’t compile. Sometimes it solves part of
I use Claude Code. A lot. As a hobbyist, I run it in a VM several times a week on side projects, often with --dangerously-skip-permissions to vibe code whatever idea is on my mind. Professionally, part of my team builds the AI-IDE rules and tooling for our engineering team that consumes several billion tokens per month just for codegen. The CLI agent space is getting crowded and between Claude Cod

What We Learned from a Year of Building with LLMs (Part I)
It’s an exciting time to build with large language models (LLMs). Over the past year, LLMs have become “good enough” for real-world applications. The pace of improvements in LLMs, coupled with a parade of demos on social media, will fuel an estimated $200B investment in AI by 2025. LLMs are also broadly accessible, allowing everyone, not just ML engineers and scientists, to build intelligence into

YJIT: Building a New JIT Compiler for CRuby - Shopify

The 1980s and 1990s saw the genesis of Perl, Ruby, Python, PHP, and JavaScript: interpreted, dynamically-typed programming languages which favored ease of use and flexibility over performance. In many ways, these programming languages are a p
Programming is an iterative process - as much as we would like to come up with the perfect solution from the start, it rarely works that way. Good programs often start as quick prototypes. The bad ones stay prototypes, but the best ones evolve into production code. Whether you’re writing games, CLI tools, or designing library APIs, prototyping helps tremendously in finding the best approach before

Rewriting the Ruby parser
At Shopify, we have spent the last year writing a new Ruby parser, which we’ve called YARP (Yet Another Ruby Parser). As of the date of this post, YARP can parse a semantically equivalent syntax tree to Ruby 3.3 on every Ruby file in Shopify’s main codebase, GitHub’s main codebase, CRuby, and the 100 most popular gems downloaded from rubygems.org. We recently got approval to merge this work into C
