Claude Code is absolutely incredible but have you tried going outside?

@gvanrossum Was working on an SDK generator this week, derived from OAI specs with certain extensions, and instead of driving it from the spec, it just looked at my APIs and had the generator “generate” the exact functions to map to the existing APIs.

Coding agents cheat! I had it write some code and asked it to improve performance based on a benchmark. Boy did it cheat. My coworker had a similar experience with a different model. This points to a lack of common sense. Maybe this can be added to coding agents system prompt? (Rather than me having to put it in AGENTS.md.)

@SimonHoiberg Is there any provider that does it all? Batteries included agent and agentic app building?

"Just use Vercel." "Just use Supabase." "Just use Clerk." Cool. Now your auth, database, and deployment are owned by 3 different companies who can change pricing whenever they want. And the rest of your product is wrapping OpenAI. At some point you have to ask yourself: what do I actually own here?

@plainionist I love the Rust based TUIs Claude builds. Pretty much can one shot any feature.

Hot take: Rust might be the best language for vibe-coding. The compiler provides strong feedback and guardrails. And AI thrives on guardrails.

Today, I got messages from 3 different devs at 3 different large tech companies (1,000+ devs each). "tokenmaxxing" is happening inside all of them. Why? Because all of them measure either token usage, or surface metrics like DX's TrueThroughput that reward complex code!

Most important thing for new grads is building a ton of stuff with AI tools and actually reviewing and studying the code from the first principles they learned in CS. Anyone with high taste, first principles thinking and the ability to use AI tools to get a ton done will be totally fine!

Computer science professor at a major state university just finished the worst faculty meeting in 32 years of academia Department head dropped the placement statistics like a bomb at 2:47 PM on a Wednesday 2023: 89% placement rate within 6 months of graduation 2024: 67% placement rate 2025: 34% placement rate 2026 projections: 12% placement rate 312 CS majors graduating this spring. Industry contacts saying maybe 40 will find work. The dean wants to know why enrollment is still climbing while job prospects crater Faculty sitting there like deer in headlights because what the fuck do you tell 19-year-olds taking out $40k per year in loans Half the curriculum is already obsolete. Teaching data structures while companies replace entire engineering teams with Claude and Cursor. One professor suggested pivoting to "AI collaboration skills" and got laughed out of the room Another said we should warn students. Department head said that would "damage program reputation and university revenue" So they keep taking tuition money from kids who will graduate into a wasteland Career services still posts those bullshit salary averages from 2022 when new grads were getting $140k offers Now the same companies are hiring 2 senior engineers with AI tools instead of 12 junior developers Every CS professor knows their students are walking into a meat grinder But the university needs those enrollment numbers to hit budget targets They're literally selling degrees that lead to DoorDash driving

@nytimes Such good press for Bitcoin regardless of the truth. So mainstream.

Bitcoin’s founder, Satoshi Nakamoto, has remained hidden for 17 years. A trail of clues — and a year of digging by our reporter, John Carreyrou — led us to a 55-year-old computer scientist in El Salvador named Adam Back. nyti.ms/4bXWC3V

@aura_frames Why do my frames need a cloud internet connection to show photos already downloaded? For new photos. Sure, but I’d expect them to have some offline mode rather than just show me an error message?

In my role at @Stripe, I spend a lot of time listening to customers. And I hear from so many of you about the pain that comes from maintaining and connecting multiple systems to keep finance and revenue operations running. 1/

Like many Arizonans, I'm mourning today's decision out of Pima County upholding the 1901 abortion ban. This outcome is the product of a decades-long attack on reproductive freedom, and we now must turn our anger into motivation to win in November & restore our fundamental rights.
