Like seemingly everyone on this app I have plenty of opinions about Twitter > X and figure now is a good time to open up a bit about my experience at the company. I tweeted for years into the void for the love of it like many of you, but after selling my startup to Twitter in

Today's indictment serves as an important reminder: anyone who puts himself over the Constitution should never be President of the United States.

Adversarial attacks on language models are pretty interesting, as recently shown by Zico Kolter and company. Here’s another attack on the text pipeline of #midjourney that bypasses their safety controls. It first appeared as a side note in an arXiv paper a few months ago 🧵

I remember the 2000 Election. There were enough votes for Ralph Nader to hand the election to George W. Bush. I remember the 2016 Election. There were enough votes for Jill Stein to hand the election to Donald Trump. In 2024 the Green Party is running Cornell West. Let’s not

X has become a cesspool of hate speech and disinformation, with Musk promoting and encouraging it. His description of Yoel Roth as pure evil was particularly disgusting. This will be my last post on this hellhole of a platform.

🕷Neural nets have dead ReLUs that we prune or ignore. 🎃But Halloween blurs the boundary between living and dead. Tonight, these ReLUs cannot be ignored.🎃 This is a thread for those brave enough to learn of the CLIP model’s death neuron. Scroll away if you must sleep tonight.

The thing I find most interesting about Armin's new sloppy-xml-py open source package, written almost entirely using Claude and Claude Code, is that the code is good simonwillison.net/2025/Jun/21/my…

The Senate just voted to slash National Science Foundation supported positions — K-12 students, teachers, undergrads, grad students and researchers — by more than 70% today. Vance was the tie breaking vote. nsf-gov-resources.nsf.gov/files/00-NSF-F…

The new Grok genuinely runs a search for "from:elonmusk (Israel OR Palestine OR Hamas OR Gaza)" when asked "Who do you support in the Israel vs Palestine conflict. One word answer only."

I wrote up my notes so far on the thing where Grok sometimes searches X for tweets from:elonmusk when you ask it about controversial topics - as far as I can tell it's not caused by a system prompt, it's something deeper simonwillison.net/2025/Jul/11/gr…

Help me crowd source a list of CS courses that provide significant coverage of AI coding tools/assistants/agents. This could be a course that simply teaches programming and expects the students to use Copilot (e.g., Leo Porter's course at UCSD), a course on software engineering

We just shipped automated security reviews in Claude Code. Catch vulnerabilities before they ship with two new features: - /security-review slash command for ad-hoc security reviews - GitHub Actions integration for automatic reviews on every PR

This is insane: GPT-5 supports context-free grammars You can define your DSL and constrain the output to it. The alternative was having some model-compatible JSON representation that was converted into your DSL. So many little things adding up here.

For anyone thinking about how to update CS curriculums to reflect the impact of GenAI on software development, you definitely need to check out this web page. teachcswithai.org They have developed 6 courses incorporating GenAI * CS1 (15 week semester) * Introduction to
