> Over the 10-year period from 2013 to 2022, the homicide conviction rate in Texas for illegal immigrants was 2.2 per 100,000, compared to 3.0 per 100,000 for native-born Americans. The homicide conviction rate for legal immigrants in Texas was 1.2 per 100,000.

It's providing platform information to PyPI to help track which operating systems and platforms are being used by different packages.

The result is useful graphs like these: https://pypistats.org/packages/sqlite-utils and https://pepy.tech/projects/sqlite-utils?timeRange=threeMonth...

The field that guesses if something is running in a CI environment is particularly useful, because it helps package authors tell if their package is genuinely popular or if it's just being installed in CI thousands of times a day by one heavy user who doesn't cache their requirements.

I love using Pyodide to build web UIs for trying out new Python libraries. Here's one I built a few weeks ago to exercise my pure-Python SQLite AST parser, for example: https://tools.simonwillison.net/sqlite-ast

In case you're open to learning, here's why I think this is useful.

The big lesson we've learned from Claude Code, Codex CLI et al over the past twelve months is that the most useful tool you can provide to an LLM is Bash.

Last year there was enormous buzz around MCP - Model Context Protocol. The idea was to provide a standard for wiring tools into LLMs, then thousands of such tools could bloom.

Claude Code demonstrated that a single tool - Bash - is actually much more interesting than dozens of specialized tools.

Want to edit files without rewriting the whole thing every time? Tell the agent to use sed or perl -e or python -c.

Look at the whole Skills idea. The way Skills work is you tell the LLM "if you need to create an Excel spreadsheet, go read this markdown file first and it will tell you how to run some extra scripts for Excel generation in the same folder". Example here: https://github.com/anthropics/skills/tree/main/skills/xlsx

That only works if you have a filesystem and Bash style tools for navigating it and reading and executing the files.

This is why I want Linux in WebAssembly. I'd like to be able to build LLM systems that can edit files, execute skills and generally do useful things without needing an entire locked down VM in cloud hosting somewhere just to run that application.

Here's an alternative swipe at this problem: Vercel have been reimplementing Bash and dozens of other common Unix tools in TypeScript purely to have an environment agents know how to use: https://github.com/vercel-labs/just-bash

I'd rather run a 10MB WASM bundle with a full existing Linux build in then reimplement it all in TypeScript, personally."},"story_title":{"matchLevel":"none","matchedWords":[],"value":"JSLinux Now Supports x86_64"},"story_url":{"matchLevel":"none","matchedWords":[],"value":"https://bellard.org/jslinux/"}},"_tags":["comment","author_simonw","story_47311484"],"author":"simonw","children":[47329651,47323803],"comment_text":"> Well, there it is, the dumbest thing I'll read on the internet all week.

AI tools get them past the awkward initial net-negative phase faster. They serve as a call option on future productivity. And they are better at AI tools than senior engineers, having never developed the habits and assumptions that slow adoption.

AI tools get them past the awkward initial net-negative phase faster. They serve as a call option on future productivity. And they are better at AI tools than senior engineers, having never developed the habits and assumptions that slow adoption.

If you accelerate the pace of code creation it inevitably creates bottlenecks elsewhere. Code review is by far the biggest of those right now.

There may be an argument for leaning less on code review. When code is expensive to produce and is likely to stay in production for many years it's obviously important to review it very carefully. If code is cheap and can be inexpensively replaced maybe we can lower our review standards?

But I don't want to lower my standards! I want the code I'm producing with coding agents to be better than the code I would produce without them.

There are some aspects of code review that you cannot skimp on. Things like coding standards may not matter as much, but security review will never be optional.

We're three years into the ChatGPT revolution now and so far the main observable impact on the craft that I care about is that I can build more ambitious things.","created_at":"2026-02-25T19:42:55Z","created_at_i":1772048575,"objectID":"47156747","parent_id":47156292,"story_id":47151564,"story_title":"What are the best coping mechanisms for AI Fatalism?","updated_at":"2026-03-05T23:37:20Z"},{"_highlightResult":{"author":{"matchLevel":"none","matchedWords":[],"value":"simonw"},"comment_text":{"matchLevel":"none","matchedWords":[],"value":"No, I hate that idea.

If you are moving faster but getting worse results it's worth stopping and examining if there are processes you could fix.","created_at":"2026-02-24T05:14:27Z","created_at_i":1771910067,"objectID":"47133109","parent_id":47132872,"story_id":47125374,"story_title":"Writing code is cheap now","story_url":"https://simonwillison.net/guides/agentic-engineering-patterns/code-is-cheap/","updated_at":"2026-03-05T23:36:08Z"},{"_highlightResult":{"author":{"matchLevel":"none","matchedWords":[],"value":"simonw"},"comment_text":{"matchLevel":"none","matchedWords":[],"value":"See my heading half way down the page!"},"story_title":{"matchLevel":"none","matchedWords":[],"value":"Writing code is cheap now"},"story_url":{"matchLevel":"none","matchedWords":[],"value":"https://simonwillison.net/guides/agentic-engineering-patterns/code-is-cheap/"}},"_tags":["comment","author_simonw","story_47125374"],"author":"simonw","comment_text":"See my heading half way down the page!","created_at":"2026-02-24T00:10:44Z","created_at_i":1771891844,"objectID":"47130969","parent_id":47127703,"story_id":47125374,"story_title":"Writing code is cheap now","story_url":"https://simonwillison.net/guides/agentic-engineering-patterns/code-is-cheap/","updated_at":"2026-03-05T23:35:59Z"},{"_highlightResult":{"author":{"matchLevel":"none","matchedWords":[],"value":"simonw"},"comment_text":{"matchLevel":"none","matchedWords":[],"value":"Claude Cowork was apparently built in less than two weeks using Claude Code, and appears to be getting significant usage already."},"story_title":{"matchLevel":"none","matchedWords":[],"value":"Writing code is cheap now"},"story_url":{"matchLevel":"none","matchedWords":[],"value":"https://simonwillison.net/guides/agentic-engineering-patterns/code-is-cheap/"}},"_tags":["comment","author_simonw","story_47125374"],"author":"simonw","children":[47127484,47129813],"comment_text":"Claude Cowork was apparently built in less than two weeks using Claude Code, and appears to be getting significant usage already.","created_at":"2026-02-23T18:45:10Z","created_at_i":1771872310,"objectID":"47126799","parent_id":47126785,"story_id":47125374,"story_title":"Writing code is cheap now","story_url":"https://simonwillison.net/guides/agentic-engineering-patterns/code-is-cheap/","updated_at":"2026-03-05T23:35:44Z"},{"_highlightResult":{"author":{"matchLevel":"none","matchedWords":[],"value":"simonw"},"comment_text":{"matchLevel":"none","matchedWords":[],"value":"Out of curiosity, are you the same person who's constantly creating brand new accounts to have a go at me or are there more than one of you?"},"story_title":{"matchLevel":"none","matchedWords":[],"value":"Writing code is cheap now"},"story_url":{"matchLevel":"none","matchedWords":[],"value":"https://simonwillison.net/guides/agentic-engineering-patterns/code-is-cheap/"}},"_tags":["comment","author_simonw","story_47125374"],"author":"simonw","children":[47128873],"comment_text":"Out of curiosity, are you the same person who's constantly creating brand new accounts to have a go at me or are there more than one of you?","created_at":"2026-02-23T18:16:30Z","created_at_i":1771870590,"objectID":"47126342","parent_id":47126260,"story_id":47125374,"story_title":"Writing code is cheap now","story_url":"https://simonwillison.net/guides/agentic-engineering-patterns/code-is-cheap/","updated_at":"2026-03-05T23:35:44Z"},{"_highlightResult":{"author":{"matchLevel":"none","matchedWords":[],"value":"simonw"},"comment_text":{"matchLevel":"none","matchedWords":[],"value":"For everyone who is responding to the "Writing code is cheap now" heading without reading the article, I'd encourage you to scroll down to the "Good code still has a cost" section."},"story_title":{"matchLevel":"none","matchedWords":[],"value":"Writing code is cheap now"},"story_url":{"matchLevel":"none","matchedWords":[],"value":"https://simonwillison.net/guides/agentic-engineering-patterns/code-is-cheap/"}},"_tags":["comment","author_simonw","story_47125374"],"author":"simonw","comment_text":"For everyone who is responding to the "Writing code is cheap now" heading without reading the article, I'd encourage you to scroll down to the "Good code still has a cost" section.","created_at":"2026-02-23T18:13:39Z","created_at_i":1771870419,"objectID":"47126291","parent_id":47125374,"story_id":47125374,"story_title":"Writing code is cheap now","story_url":"https://simonwillison.net/guides/agentic-engineering-patterns/code-is-cheap/","updated_at":"2026-03-05T23:35:44Z"},{"_highlightResult":{"author":{"matchLevel":"none","matchedWords":[],"value":"simonw"},"comment_text":{"matchLevel":"none","matchedWords":[],"value":"I want to use AI to ship more and more code faster and better.

Something I've learned from this is that semantic diffusion is real, and the definition of a new term isn't what that term was intended to mean - it's generally the first guess people have when they hear it.

"Prompt injection" was meant to mean "SQL injection for prompts" - the defining characteristic was that it was caused by concatenating trusted and untrusted text together.

But people unfamiliar with SQL injection hear "prompt injection" and assume that it means "injecting bad prompts into a model" - something I'd classify as jailbreaking.

When I coined the term "lethal trifecta" I deliberately played into this effect. The great thing about that term is that you can't guess what it means! It's clearly\nthree bad things, but you're gonna have to go look it up to find out what those bad things are.

- Running Pydantic\u2019s Monty Rust sandboxed Python subset in WebAssembly https://simonwillison.net/2026/Feb/6/pydantic-monty/ - demonstrating how easy and useful it is to be able to turn Rust code into WASM that can run independently or be used inside a Python wheel for Pyodide in order to provide interactive browser demos of Rust libraries.

- Distributing Go binaries like sqlite-scanner through PyPI using go-to-wheel https://simonwillison.net/2026/Feb/4/distributing-go-binarie... - I think my go-to-wheel utility is really cool, and distributing Go CLIs through PyPI is a neat trick.

- ChatGPT Containers can now run bash, pip/npm install packages, and download files https://simonwillison.net/2026/Jan/26/chatgpt-containers/ - in which I reverse engineered and documented a massive new feature of ChatGPT that OpenAI hadn't announced or documented anywhere

I remain very proud of my current open source projects too - https://datasette.io and https://llm.datasette.io and https://sqlite-utils.datasette.io and a whole lot more: https://github.com/simonw/simonw/blob/main/releases.md

I don't want to turn down paid work because I have a popular blog.

I have a very strong policy that I won't write about someone because they paid me to do so, or asked me to as part of a consulting engagement. I guess you'll just have to trust me that I'll hold to that. I like to hope I've earned the trust of most of my readers.

I do have a structural conflict, which is one of the reasons my disclosures page exists. I don't value things like early access enough to avoid writing critically about companies, but the risk of subtle bias is always there. I can live with that, and I trust my readers can live with it too.

I've found myself in a somewhat strange position where my hobby - blogging about stuff I find interesting - has somehow grown to the point that I'm effectively single-handedly running an entire news agency covering the world's most valuable industry. As a side-project.

I could commit to this full-time and adopt full professional journalist ethics - no accepted credits, no free travel etc. I'd still have to solve the revenue side of things, and if I wrote full time I'd give up being a practitioner which would damage my ability to credibly cover the space. Part of the reason people trust me is that I'm an active developer and user of these tools.

On top of that, some people default to believing that the only reason anyone would write anything positive about AI is if they were being paid to do so. Convincing those people otherwise is a losing battle, and I'm trying to learn not to engage.

So I'm OK with my disclosures and principles as they stand. They may not get a 100% pure score from everyone, but they're enough to satisfy my own personal ethics.

That's all true.

On Twitter their CEO said:

> It's 3M+ lines of code across thousands of files. The rendering engine is from-scratch in Rust with HTML parsing, CSS cascade, layout, text shaping, paint, and a custom JS VM.

> It kind of works! It still has issues and is of course very far from Webkit/Chromium parity, but we were astonished that simple websites render quickly and largely correctly.

That's mostly accurate too, especially the "it kind of works" bit. You can take exception to "from-scratch" claim if you like. It's a tweet, the lack of nuance isn't particularly surprising.

Keeping an eye on the tests is important. The most common anti-pattern I see is large amounts of duplicated test setup code - which isn't a huge deal, I'm much more more tolerant of duplicated logic in tests than I am in implementation, but it's still worth pushing back on.

"Refactor those tests to use pytest.mark.parametrize" and "extract the common setup into a pytest fixture" work really well there.

Generally though the best way to get good tests out of a coding agent is to make sure it's working in a project with an existing test suite that uses good patterns. Coding agents pick the existing patterns up without needing any extra prompting at all.

I find that once a project has clean basic tests the new tests added by the agents tend to match them in quality. It's similar to how working on large projects with a team of other developers work - keeping the code clean means when people look for examples of how to write a test they'll be pointed in the right direction.

Current coding agents are not up to the task of producing a production-quality web browser.

I genuinely can't imagine a better example of a sophisticated software project than a browser. Chrome, Firefox and WebKit each represent a billion-plus dollars of engineering salaries paid out to expert developers over multiple decades.

Browsers have to deal with a bewildering array of specifications - and handle websites that don't conform fully to those specifications.

They have extreme performance targets.

They operate in the most hostile environment imaginable - executing arbitrary code from the web! - so security is diabolically difficult as well.

I expect there's not a human on earth who could single-handedly architect a production grade new browser, it requires too much specialist knowledge across too many different disciplines.

On the basis, I should reconsider my 2029 prediction. I was imagining something that looked like FastRender but maybe a little more advanced - working JavaScript, for example.

A much more interesting question is when we might see a production grade browser built mostly by coding agents.

- a team of human experts driving the coding agents

- in development for at least a year

- built with the goal of "production ready Chrome competitor", not as a research project

The question then becomes who would fund such a thing - even a small team of experts doesn't come cheap, and I expect that LLM prices in 2029 will still measure in the tens or hundreds of thousands of dollars for this, if not more.

This doesn't strike me as the world's most dishonest tweet, though it exaggerates what was achieved. There IS a JS VM in there but it's feature-flagged off. The from-scratch is misleading because there are libraries handling certain aspects - most notably Taffy - which we discussed in the interview.

I just ran "cloc" and to my surprise it counted 3,036,403 (I had thought the 3M was an exaggeration) though only 1,658,651 of that was Rust.

"It kind of works" is a fair assessment IMO!

I mainly work in Python, and I've been ensuring that all of my projects have a test suite which runs cleanly with "uv run pytest" - using a dev dependency group to ensure the right dependencies are installed.

This means I can run Claude Code against any of my repos and tell it "run 'uv run pytest', then implement ..." - which is a shortcut for having it use TDD and write tests for the code it's building, which is essential for having coding agents produce working code that they've tested before they commit.

Once this is working well I can drop ideas directly into the Claude app on my iPhone and get 80% of the implementation of the idea done by the time I get back to a laptop to finish it off.

Most of the big ones are things like skia, harfbuzz, wgpu - all totally reasonable IMO.
