I’m in love with this sentence:

“The degree to which a person can grow is directly proportional to the amount of truth he can accept about himself without running away.”

A small thank you to everyone using Claude: We’re doubling usage outside our peak hours for the next two weeks.

Engineering Faculty of Peradeniya has a new BSc degree in Electronic and Intelligent Systems Engineering for those who did A/L in 2025 with Direct Entry. This is a huge win for students as it removes the uncertainty of field selection forced on them after joining a university.👏

It’s not about junior vs senior, it’s about “good with AI” vs “not good with AI.”

We just passed React on GitHub stars. 🦞

Let that sink in. A personal AI assistant built by a lobster-obsessed Austrian and an army of crustacean enthusiasts just outstarred the library that powers half the internet.

We shipped 90+ changes today. They shipped a conference.

The most efficient U.S. road trip route, as determined by a data scientist…

In 2015, data scientist Dr. Randal Olson created what he dubbed the “perfect” U.S. road trip using genetic algorithms—a type of search heuristic—to tackle the classic Traveling Salesman Problem. His aim was to chart the most efficient route visiting either 50 major national landmarks or all 47–50+ National Parks without needless backtracking. The final route stretches over 13,699 miles, covering all 48 contiguous states and iconic sites like the Statue of Liberty, the Alamo, and Yellowstone. While the pure driving time totals roughly 224 hours, most travelers would spend 2 to 3 months completing the journey with sightseeing.

Anthropic published a blog post one hour ago.

Cybersecurity stocks have lost $10B since.

CrowdStrike -6.5%. Cloudflare -6%. Okta -5.7%.

One blog post. One hour. $10B gone.

Introducing Claude Code Security, now in limited research preview.

It scans codebases for vulnerabilities and suggests targeted software patches for human review, allowing teams to find and fix issues that traditional tools often miss.

@big_duca Someone has to prompt the Claudes, talk to customers, coordinate with other teams, decide what to build next. Engineering is changing and great engineers are more important than ever.

[Naval @naval]

There is unlimited demand for intelligence.

I'm Boris and I created Claude Code. Lots of people have asked how I use Claude Code, so I wanted to show off my setup a bit.

My setup might be surprisingly vanilla! Claude Code works great out of the box, so I personally don't customize it much. There is no one correct way to use Claude Code: we intentionally build it in a way that you can use it, customize it, and hack it however you like. Each person on the Claude Code team uses it very differently.

So, here goes.
