« Je rappelle qu’on a été les seuls, et j’ai été la seule à dire tous les soirs sur CNews et Europe 1 le nom des otages français.

Pourquoi tous les médias ne l’ont pas fait ? Ce n’étaient pas des Français ? On l’a fait pour les otages dans les années 80 au Liban. Pourquoi on ne l’a pas fait pour les otages français en Israël ? C’était pas important ?

Jusqu’au dernier jour, jusqu’au dernier otage libéré, j’ai donné leur nom parce que je trouvais que c’était vraiment ma mission. »

Durant cette période si douloureuse qui a suivi le 7 octobre 2023, Laurence Ferrari aura fait partie de ces très rares personnes qui se sont comportées comme des Justes, refusant de détourner le regard, et ça, jamais nous ne l’oublierons.

Merci @LaurenceFerrari ❤️

This is what antisemitism has always looked like. Take successful companies, list them out, add “Jewish,” pretend you discovered something.

THIS DAD VIBE CODED A LANGUAGE LEARNING APP FOR HIS DAUGHTER THAT LETS KIDS POINT THEIR CAMERA AT ANYTHING AND LEARN THE WORD

he made it so his daughter could point her phone at anything around her and learn the word for it

you take a photo of an object, the app removes the background, identifies what it is, and teaches you the word in whatever language you're learning

the ui and animations are clean, polished, and the app is easy to use

he started building it for his kid and got obsessed with making it perfect

the app won an apple design award which is one of the hardest things to get in the entire iOS ecosystem. apple picks like 12 apps a year out of millions

it went from a dad building something for his daughter to one of the best designed apps on the app store

my life is so weird man. it's all claude. he does all my work. if anyone has questions i just pipe it to claude. he plans my days. my weeks. months. i just bought a bracelet for my wife that claude suggested. while at the gym doing the set claude gave me

This was the first AI-planned drive on another planet. And it was planned by Claude.

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 available over the last ~year and a failure to claim the boost feels decidedly like skill issue. There's a new programmable layer of abstraction to master (in addition to the usual layers below) involving agents, subagents, their prompts, contexts, memory, modes, permissions, tools, plugins, skills, hooks, MCP, LSP, slash commands, workflows, IDE integrations, and a need to build an all-encompassing mental model for strengths and pitfalls of fundamentally stochastic, fallible, unintelligible and changing entities suddenly intermingled with what used to be good old fashioned engineering. Clearly some powerful alien tool was handed around except it comes with no manual and everyone has to figure out how to hold it and operate it, while the resulting magnitude 9 earthquake is rocking the profession. Roll up your sleeves to not fall behind.

Google will never sell TPUs. The moment Google sells TPUs at scale, they transform their architectural advantage into a commodity.

Google's internal teams have first-order claims on TPU capacity because those workloads directly generate revenue and strategic moats. Any TPU sold externally is a TPU not used to defend Google's primary profit engines.

Right now, TPUs are Google's proprietary edge, vertical integration that lets them operate AI infrastructure at costs competitors can't match. DeepMind can burn through compute budgets that would bankrupt OpenAI because Google doesn't pay retail GPU prices, they pay internal TPU marginal cost.

If Google starts selling TPUs externally:
- They have to price competitively vs Nvidia GPUs, which means revealing their cost structure. Suddenly, everyone knows Google's true AI compute costs aren't magic.
- Selling bare metal TPUs means publishing detailed specs, performance benchmarks, and programming interfaces. This is handing competitors a blueprint for "how Google actually does AI at scale." Right now, that's proprietary. The moment it's a product, it becomes studied, reverse-engineered, and eventually replicated.
- Google Cloud already sells TPU access via GCP at premium prices. If they start selling bare TPUs, they're competing with their own higher-margin cloud offering. No sophisticated buyer would pay GCP markup when they could buy TPUs directly and run them cheaper.

GCP TPU pricing is not aggressive compared to GPU alternatives, but it is premium. This isn't incompetence, it's intentionally priced to discourage massive external adoption. Google makes TPUs available enough to avoid antitrust "hoarding infrastructure" accusations and to capture some high-margin cloud revenue, but they don't actually want external customers consuming capacity at scale.

Compare this to AWS, which sells every chip they can manufacture (Graviton, Trainium, Inferentia) because AWS is a commodity infrastructure business. Google's core business is ads and consumer products that depend on AI infrastructure. Selling the infrastructure is like McDonald's selling their supply chain to Burger King, even if it generates revenue, you're strengthening competitors and weakening your primary business.

You can't simultaneously be a commodity chip vendor AND maintain proprietary infrastructure advantage. The moment you sell, you commoditize. The moment you commoditize, your advantage evaporates.

Given that selling TPUs appears strategically unsound, why is there speculation that Google pursue it anyway? I think because cloud divisions at every hyperscaler have perpetual "we need differentiation" anxiety, and custom chips look like differentiation. But differentiation only matters if it protects margins or captures share without destroying your core business. Google selling TPUs would be differentiation that destroys more value than it creates.
