Building a toy browser
In the last several weeks, I have been building a toy browser based on an online book, Web Browser Engineering. As someone who spent a fair share of his career on web frontend, it was eye-opening and satisfying. It felt like I had been living on one side of a wall for years and finally visited the other side of the wall. I imagine other web frontend folks would like it as well. The book Web Browse
Rust Is Eating JavaScript 2021 (updated 2026) – Lee Robinson Rust is a fast, reliable, and memory-efficient programming language. It’s been voted the most admired programming language for a decade1. Created by Mozilla, it’s now used at Meta, Apple, Amazon, Microsoft, and Google for systems infrastructure, encryption, virtualization, and more low-level programming. Why is Rust now being used to rep

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

Couple of weeks ago when I was publishing The Hidden Cost of URL Design I needed to add SQL syntax highlighting. I headed to PrismJS website trying to remember if it should be added as a plugin or what. I was overwhelmed with the amount of options in the download page so I headed back to my code. I checked the file for PrismJS and at the top of the file, I found a comment containing a URL: /* http
I left OpenAI three weeks ago. I had joined the company back in May 2024. I wanted to share my reflections because there's a lot of smoke and noise around what OpenAI is doing, but not a lot of first-hand accounts of what the culture of working there actually feels like. Nabeel Qureshi has an amazing post called Reflections on Palantir, where he ruminates on what made Palantir special. I wanted to
How uv got so fast
uv installs packages faster than pip by an order of magnitude. The usual explanation is “it’s written in Rust.” That’s true, but it doesn’t explain much. Plenty of tools are written in Rust without being notably fast. The interesting question is what design decisions made the difference. Charlie Marsh’s Jane Street talk and a Xebia engineering deep-dive cover the technical details well. The intere
This all started with a blog post back in 2020, from a tech curiosity: what's the fastest way to scale containers on AWS? Is ECS faster than EKS? What about Fargate? Is there a difference between ECS on Fargate and EKS on Fargate? I had to know this to build better architectures for my clients. In 2021, containers got even better, and I was lucky enough to get a preview and present just how fast t

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
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 begin as quick prototypes. While many experiments remain prototypes, the best programs can evolve into production code. Whether you’re writing games, CLI tools, or designing library APIs, prototyping helps tremendously in finding the best
TL;DR GitHub issueの自動解決能力を測るSWE-bench Verifiedが15ヶ月で33%から80%へ急速に進化しました（Claude Opus 4.5）。本記事では、形式手法・帰納的学習・エージェント研究という三つの流れが2020年代に収束した結果と捉えています。 ただし80%はベンチマーク飽和の兆候でもあり、SWE-bench Proでは40%台に落ちます。評価は次々と難しいベンチマークへ移行しています。 生産性への影響は文脈に依存します。ジュニア開発者や不慣れなコードベースでは効果的ですが、熟練開発者が慣れた環境で使うと逆効果という報告もあります。むしろ質的変化として、エンジニアの役割は「コード作成者」から「AIの監督者」へ移行しています。 大規模言語モデル（LLM）の能力については学術的議論が続いています。「洗練されたパターンマッチング」という批判と「創発的な理

In order to create a Python package, you need to write the code that implements the functionality you want to put in your package, and then you need to publish it to PyPI. That is the bare minimum. Nowadays, you can also set up a variety of other things to make your life easier down the road: continuous testing of your package;
Yesterday I was thinking about how long it took me to get a colorscheme in my terminal that I was mostly happy with (SO MANY YEARS), and it made me wonder what about terminal colours made it so hard. So I asked people on Mastodon what problems they’ve run into with colours in the terminal, and I got a ton of interesting responses! Let’s talk about some of the problems and a few possible ways to fi

CUPID: for joyful coding
What started as lighthearted iconoclasm, poking at the bear of SOLID, has developed into something more concrete and tangible. If I do not think the SOLID principles are useful these days, then what would I replace them with? Can any set of principles hold for all software? What do we even mean by principles? I believe that there are properties or characteristics of software that make it a joy to
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!

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.

I first learned Kubernetes ("k8s" for short) in 2018, when my manager sat me down and said "Cloudflare is migrating to Kubernetes, and you're handling our team's migration." This was slightly terrifying to me, because I was a good programmer and a mediocre engineer. I knew how to write code, but I didn't know how to deploy it, or monitor it in production. My computer science degree had taught me a
Here’s a niche terminal problem that has bothered me for years but that I never really understood until a few weeks ago. Let’s say you’re running this command to watch for some specific output in a log file: tail -f /some/log/file | grep thing1 | grep thing2 If log lines are being added to the file relatively slowly, the result I’d see is… nothing!

When we launched Cloudflare Sandboxes last June, the premise was simple: AI agents need to develop and run code, and they need to do it somewhere safe. If an agent is acting like a developer, this means cloning repositories, building code in many languages, running development servers, etc. To do these things effectively, they will often need a full computer (and if they don’t, they can reach for
