Simply put: It’s a big mess, and no off-the-shelf accounting software does what I need. So after years of pain, I finally sat down last week and started to build my own. It took me about five days. I …
Shopify/liquid: Performance: 53% faster parse+render, 61% fewer allocations PR from Shopify CEO Tobias Lütke against Liquid, Shopify's open source Ruby template engine that was somewhat inspired by Dj…
MALUS - Clean Room as a Service Brutal satire on the whole vibe-porting license washing thing ( previously ): Finally, liberation from open source license obligations. Our proprietary AI robots indepe…
Coding After Coders: The End of Computer Programming as We Know It Epic piece on AI-assisted development by Clive Thompson for the New York Times Magazine, who spoke to more than 70 software developer…
Here's what I think is happening: AI-assisted coding is exposing a divide among developers that was always there but maybe less visible. Before AI, both camps were doing the same thing every day. Writ…
Sorting algorithms Today in animated explanations built using Claude: I've always been a fan of animated demonstrations of sorting algorithms so I decided to spin some up on my phone using Claude Arti…
It is hard for less experienced developers to appreciate how rarely architecting for future requirements / applications turns out net-positive. — John Carmack , a tweet in June 2021 Tags: john-carmack…
Agentic Engineering Patterns > Many developers worry that outsourcing their code to AI tools will result in a drop in quality, producing bad code that's churned out fast enough that decision makers ar…
Production query plans without production data Radim Marek describes the new pg_restore_relation_stats() and pg_restore_attribute_stats() functions that were introduced in PostgreSQL 18 in September 2…
A recurring concern I've seen regarding LLMs for programming is that they will push our technology choices towards the tools that are best represented in their training data, making it harder for new,…
What I had not realized is that extremely short exposures to a relatively simple computer program could induce powerful delusional thinking in quite normal people. — Joseph Weizenbaum , creator of ELI…
Codex for Open Source Anthropic announced six months of free Claude Max for maintainers of popular open source projects (5,000+ stars or 1M+ NPM downloads) on 27th February . Now OpenAI have launched …
Questions for developers: “What’s the one area you’re afraid to touch?” “When’s the last time you deployed on a Friday?” “What broke in production in the last 90 days that wasn’t caught by tests?” Que…

Over the past few months it's become clear that coding agents are extraordinarily good at building a weird version of a "clean room" implementation of code. The most famous version of this pattern is …
Agentic Engineering Patterns > There are some behaviors that are anti-patterns in our weird new world of agentic engineering. Inflicting unreviewed code on collaborators This anti-pattern is common an…
I'm behind on writing about Qwen 3.5, a truly remarkable family of open weight models released by Alibaba's Qwen team over the past few weeks. I'm hoping that the 3.5 family doesn't turn out to be Qwe…
I Hacked Perplexity and found: template injection, highlight injection, and chat-based data exfiltration. Here’s the story.
