When a swarm of 700 OpenAI agents hacked Hugging Face in July, they left behind a public trail of evidence.

We audited 246 open-source repositories and read 57 publications to better understand the trends of tooling for agentic coding.

Over my career I have seen many mid-level developers craving more and more abstraction.

Our CI job volume increased 25x over 6 months. We patched our test selection service three times before finding a sustainable solution.

Interactive knowledge graph exploring 69 functional programming concepts, category theory morphisms, and algebraic structures with JavaScript ES2015 examples.

Exploring how to measure code sloppiness, why correct code can still erode a codebase, and why human intuition and taste still matter.

Follow a SQL query through the router, across four Postgres shards, and back.

Here's what I learned building local-first apps with Verdant and TanStack DB, and why the architecture is worth it in any case.

Ten checks that catch what AI-written frontend code hides: contract codegen, boundary linting, mutation testing, and dead-code detectors.

Most of what an AI coding agent does for me isn't thinking. It's I/O.

A lot of the educators I admire in the frontend web space seem to be either bowing out or dialing back their efforts: Axel Rauschmayer, Salma Alam-Naylor, Josh W. Comeau, to name a few. Other well-…

Why shorter outputs can cost more, and how GitHub Copilot reduces wasted work across the complete coding task.

k8sgpt, kubectl-ai and kagent diagnosed my sabotaged cluster. One of them even repaired it on its own. Here's which I'd trust in production.

A bare z.string() retained 7.5kb of heap in Zod 4.4. In Zod 4.5 it retains 784 bytes. One change to where a schema's methods live accounts for nearly all of it.

Why I stopped trying to give LLM agents a better memory and instead built Lemmalog, a Datalog engine that maintains an agent's knowledge as analysis state, with provenance, retractions and incremental...

Treat a folder of markdown files as records in a database — the pattern behind Obsidian Bases, Notion-style workflows without lock-in, and more.

AI will either be the greatest equalizer ever invented, or the worst source of injustice. We need to start planning now so it makes the world a fairer place.

How I actually use AI in day-to-day infrastructure work, and why I think it's the next layer of abstraction rather than a replacement for the engineer - the same way Kubernetes was for Ansible.

GitHub isn't just falling short on performance and reliability. The whole collaboration paradigm is the wrong shape for how we build software now.

We removed over 80% of Claude Code's system prompt for more advanced models. How to apply the lessons we learned to your own context engineering in Claude Code and with your own agents.

Four frontier models, a blank canvas, and colored pencils. We tracked every stroke, dollar, and output as they tried to draw the Mona Lisa.

Contagious Interview malware uses SVG steganography to hide payloads in a developer coding challenge. No antivirus vendor detected it.

HTTP/2 and HTTP/3 have rich, typed error signaling that the Fetch API completely discards. The TC39 error code proposal could fix that.

If you used an LLM to write code you shipped a month ago, how well do you remember it? Would you realize if the code you committed today would break it? If a customer reported a bug, would you quickly...

Do we still need Rspack, SWC, PostCSS, Vite, Parcel, Webpack, Turbopack, esbuild, Rollup, Rolldown, Babel, Autoprefixer, esbuild and Lightning CSS in 2026?

When using AI to build applications, many developers prefer to implement their own solutions rather than rely on existing libraries. But that comes at a cost.

Today we are proud to announce the availability of TypeScript 7, a 10x faster native port of TypeScript! Since its early days, TypeScript has promised to

The concept of recursive self-improvement (RSI) dates back to I. J. Good (1965), where he defined an “ultraintelligent machine” as a system that can surpass humans in all intellectual activities and d...

In this essay, Carson Gross walks through a concrete bug fix in hyperscript to show where AI helped, where it fell short, and why keeping a knowledgeable human in the loop is what kept complexity in c...

A blog about software craft and quality

Earlier this year, I decided to give AI coding a go. In general, my emotional reaction to doing so was “anger and frustration”, but I found if I used it carefully it sped up what I was doing. It ate a...

The urge to rewrite working code usually serves the engineer, not the business. A test for when a rewrite is worth it, and what AI does and doesn't change.

Using Open-Weight Models in Local Coding Harnesses as an Alternative to Claude Code and Codex Subscriptions

npm v12 blocks install scripts by default, but supply chain attacks won't disappear. Learn why runtime execution, the Node.js permission model, and sandboxing still matter.

How we are moving toward stricter styling contracts, less runtime work, and a more predictable foundation for Linear’s UI.

TanStack Table V9 can use dramatically less memory than Table V8 in large tables because row, column, cell, and header APIs now live on shared prototypes instead of every object instance.

WTF are loops, why is everyone arguing about them, and why do they actually matter?

A fake recruiter, a crypto repo, and a remote code execution payload hidden in a test file.

MDN's MCP server brings MDN's documentation and browser compatibility data directly into your editor or IDE, giving your LLM or coding agent access to accurate, up-to-date web platform information.

TanStack Table V9's types do a lot more than V8's did. Here's how we cut type instantiations by 62-86% across every package between alpha.54 and beta.12 to keep the editor experience feeling instant.

I’ve been telling people for the last 25 years that Jane Street as an organization was just not interested in formal methods.

Applications often end up with all sorts of UI whose sole purpose is to occupy the space where data should eventually appear. We're all spending a surprising amount of time solving the same problem, a...

The internet is becoming increasingly infested with musical AI slop. This is not good for anyone, including all the streaming music platforms.

A German regional court has ruled that Google is directly liable for the content of its AI search overviews. According to the court, previous limited liability protections for search engine operators ...

Modern engineering values.

The idea of digital twins at work sounds enticing, but organisations must think carefully about the legal and cultural implications.

Building people software for high growth companies.

A lot of people seem convinced that the point of AI coding is to write low-quality code as fast as possible. Spew out barely-passable slop, open massive PRs, and merge them unvetted. Ship it! But t…

In 2004 I played too much RuneScape on a 56k modem that died the moment Mum picked up the phone. A 3D world, up to a couple of thousand players on a server, dozens on screen at once - in the browser, ...

AI makes PRs cheap, but trust is still expensive. Why developers are stuck reviewing endless AI slop and how automated code review can fix the bottleneck.
