If you're a PM or people manager, I'd thoroughly recommend The Look & Sound of Leadership podcast for leadership and communication coaching tips. European friends: it's very, very American - but go with it. Thanks @shreyas for the tip.

I'm being accused of overhyping the [site everyone heard too much about today already]. People's reactions varied very widely, from "how is this interesting at all" all the way to "it's so over". To add a few words beyond just memes in jest - obviously when you take a look at

Team onboarding in 2026: - Hereโ€™s a list of links for your agent to sift through - These Claude slash commands great for refreshing context - Hereโ€™s a dump of raw research transcripts - Hereโ€™s a key disambiguation / synonym file so Claude searches efficiently

I wanted to share something I built over the last few weeks: https://t.co/QRqMK9CpTR is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code.

Remember this the next time people gaslight you with anti data center crap. Speaking of gaslighting: Canada flares off 7 GW of natural gas as a waste product of mining each year- more power than all the LLM training clusters use combined. Letโ€™s build data centers in Alberta.

Narrative violation: The largest AI data center uses roughly the same amount of water as two burger joints. There are over 200,000 fast food restaurants in the U.S. so this is a tiny amount.

There are two ways to vibe code: Output oriented Curiosity oriented The latter is more satisfying long-term, makes you better at it and for non-devs make you more like a dev long-term.

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

It's really poor you can't opt out of Gemini using your chat history for human review and model training without turning off history. That'll be a huge barrier to it being a default tool for many.

@karpathy I feel this way most weeks tbh. Sometimes I start approaching a problem manually, and have to remind myself โ€œclaude can probably do thisโ€. Recently we were debugging a memory leak in Claude Code, and I started approaching it the old fashioned way: connecting a profiler, using the

I've never felt this much behind as a programmer. The profession is being dramatically refactored as the bits contributed by the programmer are increasingly sparse and between. I have a sense that I could be 10X more powerful if I just properly string together what has become

I suspect @OpenAI could massively improve dev model adoption if they just sorted out naming. It makes extremely obscure how they compare to Claude models. Suggestion @sama for the next update: gpt-5.3-codex-ultra gpt-5.3-codex gpt-5.3-codex-mini

One client store in early access for @Shopify Product Network earned $1,381.92 in commissions just last month from their Order Status and Thank You pages. For doing nothing. It's pure profit.

I've never bought into the idea of a fixed TAM. Instead of fighting over a piece of the pie, what if we grow the pie instead? What if we focused on collaboration instead of competition? Introducing the Shopify Product Network. Now, when a customer searches your store for
