Did the @bsky.app remove the shared follows in the profiles? (people I follow that also follow this profile) That was the best signal I had to filter out bots, impersonators, and just low signal profiles 😒

Life is full of things that, by complexity or design or lack of care or required time, are hard to navigate: healthcare, government, personal finance, school forms are all among them It is why I feel consumer AI is underrated. People muddle by, but are missing support & AI is good enough to help.

Thanks to the video from the Black Hat security conference of OpenAI's presentation about "The Hugging Face Incident" we now have a detailed timeline of what happened from OpenAI's perspective - I wrote up the details here, it's pretty wild simonwillison.net/2026/Aug/7/o...

I am learning so much about architecture by vibe coding i didn't know terms like seam, or testing vertical slices. I did knew them intuitively but I was struggling to communicate that to LLMs Also a shoutout to @mattpocock.com 's YT channel for helping me solidify these and other concepts

This is codex, I just asked him to find the root cause of a health issue by only asking yes/no questions. And now I don't know how to continue 🤦‍♂️

In memory of all the walls AI was about to hit.

Everyone wants to blame the content: misinformation, bots, polarisation. That mistakes catalysts and symptoms for the underlying causes. The crisis isn’t bad information, it's that the very information infrastructure we relied on to create a shared understand of the world had changed completely.

I wrote about Clawdbot/Moltbot/OpenClaw and Moltbook, the fascinating, weird and sometimes even useful social network for digital assistants to swap tips and gossip with each other simonwillison.net/2026/Jan/30/...

I hope this also serves as a signal that International rules need big reforms towards recovering democracy

oh this is neat — Qwen’s newest image model decomposes images into layers (how photoshop works), and you edit just one layer and nothing else qwen.ai/blog?id=qwen...

I am increasingly starting to suspect that a good chunk of our social problems with social media is selection bias in disguise

Claude Skills are awesome, maybe a bigger deal than MCP simonwillison.net/2025/Oct/16/...

1/ 🚨 NEW NPM MALWARE CAMPAIGN. Yes, another. North Korea’s “Contagious Interview” campaign is escalating: 338 malicious npm packages, 50,000+ downloads -- 25 still live. Aimed at Web3/crypto devs & job seekers via slick recruiter DMs → git clone → npm install → compromise.

(The same thing extends to prompt injection. Human employees are often tricked, scammed or phished, and that’s the baseline that computers need to beat.)

Both these are true.

You can just make things on the web collaborative by adding a single HTML attribute...

This is a delightful following to lean's natural numbers game but for the reals adam.math.hhu.de#/g/AlexKonto... it's made by Alex Kontorovich and it's accompanied by a video series (a class recording) on YT youtu.be/U2oCgeVgd9M?... @danabra.mov you might be interested in this

12 exciting live-programming projects will be presented at LIVE this year. It's free, online, and coming up soon! Sat 9/27: Videos premiere Sat 10/4: Q & A and discussion over Zoom Details on projects are up already at liveprog.org; more schedule & links coming soon. Hope to see ya there!

fun fact: Lean can represent real numbers not floats (although Lean can do them). not doubles. not even arbitrary precision floats, but *actual* reals — which includes the squared root of 2, the exact number Pi (not an approximation!), fractions like 0.111... and so on. this still blows my mind

This is using the highlights API to color raw text like for example this code in a pre tag with no need for nested tags in between the code This is really cool because you can now make a very simple contenteditable editor with color highlighting without needing to fix cursor position on each edit

I'm up to 124 little mostly-vibe-coded apps on my tools.simonwillison.net site and most of them are trivial but some of them aren't, so I wrote up this guide to the ones I think are most worth checking out simonwillison.net/2025/Sep/4/h...

I've open sourced Ripple! github.com/trueadm/ripple It's super early days, not much works and there's little to no documentation or guidance. Plus the codebase is raw, but I at least wanted to share my ideas with the community. :)

I've had so many folks ask now, that I had to go for it. You asked me to build that ideal Inferno X framework that I described ages ago, so I went ahead and did just that. I built something that actually works and, well, it works well. Oh, and doesn't use signals!

a social media that is more like a wikipedia rabbit hole, giving you more and more posts that fit down that direction of latent space

which will burst first? the AI bubble… …or the “AI is a bubble” bubble?

my point isn’t so much that manual curation would “replace” algorithmic feeds. it’s that (imo!) curation and ranking need to be decoupled. the primitive i want (post lists) is the most basic form of curation possible. so that feels like the first step in decoupling them. like pinterest collections

Now I'm even more interested in learning Lean 🤩

😂

I believe we need a plurality of new guiding metaphors for browsers that recenter the end-user and provides a security model that supplants SOP. It's important to not throw away the internet we already built and start over, we must figure out how to reappropriate it.

Google's Genie 3 is a controllable world model and it looks incredible

You may not feel it, but the ground beneath you may be sinking. In fact, the surface of California’s Central Valley is nearly 30 vertical feet lower than it was a century ago. Why is this happening? Because our planet is rapidly drying. THREAD/

For software to be malleable, we need ways of building and modifying programs that are accessible to many more people. Are you working on new interfaces for programming? Share your progress at the LIVE workshop! Submissions are due July 21st. liveprog.org (Happy to chat if you have questions!)

canvasifying is a really cool demo

very interesting comment on the original thread mathstodon.xyz/@johncarlosb...

this post is so good My vibes resonate, we live in times where the more rebellious thing one can do, ironically, is to be an establisher

i feel like most people are seriously underusing markdown. it's not just for links and lists — it's a full-on superset of HTML! here are a couple of my favorite favorite tricks:

this cool, they're using git worktrees to run multiple instances of Claude in different branches to run them in parallel And they got a script that it seems to handle all the complexity of doing that so you don't even have to think about git worktrees

I really liked this blog post by @jeremiahdjohns.bsky.social: open.substack.com/pub/infinite... "Persistence beats talent" is honestly quite inspiring
