reminders for creative people in tech: - your weird taste is your edge - you don't need permission to make things - small daily work beats one big launch - 'unemployable' is a compliment if your work is good enough - one great post can do more than a year of applying to jobs - be delusional and cringe, or you'll be like everyone else - the people you deeply admire started out bad too - the internet rewards people who show up

We recently added /storage to the desktop app! You can see how much disk space Claude is using on your computer and clear out inactive tasks and unused worktrees.

The coding interview is dead, at least for my team at Anthropic. I've seen enough to know that it no longer provides signal. I removed it from loops this month. I have a spicy, optimistic take - I think there's an opportunity for junior engineers: felixrieseberg.com/hunger-be…

We launched OSS Scanner, which gives critical open source projects free, periodic vulnerability scans from our strongest models. Each finding includes a proof-of-concept, and a patch where possible. red.anthropic.com/oss-scanne…

Sé que es polémico, pero si gracias a la IA no reducimos la jornada laboral a menos días, será una gran cagada.

We've been working hard on making the Claude Code desktop app great for running lots of sessions side by side. It's now much quicker to start sessions, easier to split work across a few, and you can always see what each of them is doing. Here’s what's new:

New on our Engineering blog: Creating in-house source control. In May, we merged around 2,500 code changes per day. In September, we merged more than 30,000 per day. As a result, we became bottlenecked by developer infrastructure built for human (rather than agent) scale. Here, we share how we built a new version control system—and fully migrated our monorepo from git—in five months: anthropic.com/engineering/re…

say it with me now. experts are fake, smart generalists rule the world, everything is designed by people no smarter than you, and courage is in shorter supply than genius

said that last year, saying it again. vibes coding is a slur.
it’s clear we need to retire the term vibe coding because the models now produce better architecture & way more coherent code than an average software engineer. perhaps even better than top software engineers too because unlike a human, ai has a much much larger context window. this ain’t vibe coding at all. it’s precision engineering.

> posts regularly about how much money he makes with custom software > launches new viral apps regularly > Builds software daily with AI > tells everyone software is dead > keeps building software Please stop taking these people seriously.
Software is dead It's now the era of personal software and everyone just builds what they need whenever they need it I think

At this point I consider @Cloudflare to be a headless company. I use it everyday (work + side projects) but I only very rarely use the UI. I used it today to store an API key and it felt odd. Best tools are the ones I don't have to look at because they just work.

Introducing Claude Haiku 5.5: the cheapest, fastest, and most capable small model we’ve ever released. On average, it costs around 75% less to run than Claude Haiku 4.5.

I have a serious disease, and that is overbuilding. My mind keeps thinking about adding new features and avoiding marketing. How can I overcome this mindset?

Claude has discovered a previously unknown enzyme system hidden in the DNA of bacteriophages. Beside the enzyme’s gene sits a long array of repeating DNA—a structure that looks somewhat similar to CRISPR. We don’t yet understand what this system does, but only a handful of known systems share its features, and all of them are able to cut, copy, and paste DNA. Historically, the discovery of such programmable systems has helped revolutionize medicine. CRISPR, for instance, is now the foundation of genetic medicines. But it will take much more work to learn what this system does, and whether it can be put to similar use. Read more: anthropic.com/news/claude-di…
