@KevinOConnor I think Kevin drafted Evan on his fantasy Team. Like, it’s my same type of rage when a pick doesn’t work.

We knew we created a great product but we never expected the reception to be this incredible. The feedback on taste, gut and performance has been amazing. To everyone whose training block got disrupted mid-build by the stock outs, we’re sorry. That’s on us and we’re working hard to make sure it never happens again! 😬 Gels are back in stock and live on the site now. Fuel for your Daily discipline.

Anuncios de Amarok: Único dueño. 44,500KM. Uso de ciudad. No campo. No para remolcar. La caja no se usó nunca, salvo para llevar unas macetas que compré en el vivero. Service cada 8000KM con Motul 8100 y solamente cargada con Shell V Power Diesel. Tratamiento cerámico 💅 Anuncios de Hilux: Tercer dueño. Repatriada de Afganistán (se le sacó la ametralladora que traía en la caja). 796000KM. Sólo se usó en el campo remolcando cosechadoras. Motor nunca se abrió (ni tampoco la tapa del capot).

Tengo otras licitaciones igual de truchas a las que sólo les falta la firma de Adorni, como la “gestión y análisis de datos en tiempo real” (4.960.988 dólares) y los “servicios de apoyo para la mejora de sistemas de información” (1.129.999 dólares), ambas a punto de ser adjudicadas a la misma empresa, que jamás había participado de una licitación pública hasta que llegaron estos delincuentes. Ampliaré. Sumen todo y les da más de 10 millones de dólares. Gobierno de vagos, grasas, hijos de puta y, sobre todo, corruptos. Fin.

Les voy a contar cómo @madorni se está choreando millones de dólares (dólares, no pesos) del Estado con licitaciones truchas para mandar mensajes de texto y correos electrónicos. Lo de los viajes son monedas al lado de esto. Pasen y vean 👇🧵

GPT está funcionando muy muy mal. A punto tal que incluso el thinking mode me inventó fuentes, incluyendo links truchos de Pubmed. Inusable.

After months of design, prototypes, and manufacturing. This is the first real @petpinai device. Seeing the finished hardware for the first time is surreal. More soon.

The last car we bought was a @Tesla Model Y. Painless purchase process. No salespeople, no showroom, no upsells, no games, no haggling, no pressure. Just a personal choice on my own time, and a simple few-minute process handled entirely via a clear and straightforward app. The next car we're buying is from another brand. And holy hell, it feels like I'm going back in time. Salespeople, back-and-forth charades, pricing games, "when can you come in?" before the deal is finalized tactics, etc. And I'm still doing it all via email so I don't have to deal with the showroom antics. I've modernized the process as much as I can from my side, and yet it's the same old same old. They don't even feel like the same thing. In one case I'm buying a car with all the baggage that comes with buying a car. In the other case I'm buying a Tesla with none of the baggage of buying a car. This experience could make me lament this other brand, but what it really does is make me appreciate and respect the lengths to which Tesla has fully reconfigured the car buying experience. It's become effortless, like buying any other product. As it should be. A car is just another product. Bravo.

@tim_roozendaal Love this. Also, ideally don’t do just one exercise though. :)

Hip airplanes might be the single best exercise for runners. This exercise focuses on so much at once. → Foot splay → Lower leg rotation → Hip stability → Hip strength in multiple planes of motion If you're only doing one exercise outside of running, make it this one.

@clwdbot @aakashgupta Agree with Vaclav here. And I’m not that optimistic that all companies will work with a data-sharing-by-default mindset. Incentives are not that clear.

the part the OS analogy misses: every prior platform converged. Windows won. iOS won. the personal agent OS diverges by design. your cardio tracker shares zero code with mine. no shared bug reports, no community plugins, no stack overflow answers. Karpathy can debug his own imperial/metric conversion bug. the 99% who can't are going to need a very different kind of support ecosystem than anything we've built before.

Karpathy is describing a personal operating system and most people are reading this as a post about fitness apps. Think about what actually happened here. He had a goal (lower RHR from 50 to 45), a sensor (Woodway treadmill), a protocol (Zone 2 + HIIT), and a timeline (8 weeks). The LLM stitched all of that together into a custom interface in an hour. No app store. No searching for the least-bad option. No adapting his workflow to someone else's UI. That's what an operating system does. It sits between you and your hardware, manages your resources, and renders the interface you need at the moment you need it. The PC era gave us one OS across all applications. The mobile era gave us one OS across all apps. The agent era gives us one OS across all of life. Your health data, your finances, your work projects, your home automation, all brokered through a single layer that already has your context and builds the interface on the fly. The 1 hour to 1 minute gap Karpathy identifies maps cleanly to how long it took early operating systems to mature. First you had to write your own drivers. Then hardware manufacturers standardized interfaces. Then plug-and-play emerged. Woodway not having an API is the equivalent of needing to write your own printer driver in 1994. Annoying, but temporary. The real unlock is the context layer. Karpathy's agent already knows his RHR baseline, his training history, his schedule. A cold-start app never does. Every bespoke app the agent builds gets better because every previous app taught it more about you. That's a compounding advantage no app store can replicate, because app stores don't share state across apps. Your agent does. We're watching the early boot sequence of the personal agent OS. It's clunky. You have to notice bugs and flag unit conversion errors. But the trajectory is the same one we saw with every prior computing platform: hardware standardizes its interfaces, the OS layer gets smarter, and the user stops thinking about the plumbing entirely.

Very interested in what the coming era of highly bespoke software might look like. Example from this morning - I've become a bit loosy goosy with my cardio recently so I decided to do a more srs, regimented experiment to try to lower my Resting Heart Rate from 50 -> 45, over experiment duration of 8 weeks. The primary way to do this is to aspire to a certain sum total minute goals in Zone 2 cardio and 1 HIIT/week. 1 hour later I vibe coded this super custom dashboard for this very specific experiment that shows me how I'm tracking. Claude had to reverse engineer the Woodway treadmill cloud API to pull raw data, process, filter, debug it and create a web UI frontend to track the experiment. It wasn't a fully smooth experience and I had to notice and ask to fix bugs e.g. it screwed up metric vs. imperial system units and it screwed up on the calendar matching up days to dates etc. But I still feel like the overall direction is clear: 1) There will never be (and shouldn't be) a specific app on the app store for this kind of thing. I shouldn't have to look for, download and use some kind of a "Cardio experiment tracker", when this thing is ~300 lines of code that an LLM agent will give you in seconds. The idea of an "app store" of a long tail of discrete set of apps you choose from feels somehow wrong and outdated when LLM agents can improvise the app on the spot and just for you. 2) Second, the industry has to reconfigure into a set of services of sensors and actuators with agent native ergonomics. My Woodway treadmill is a sensor - it turns physical state into digital knowledge. It shouldn't maintain some human-readable frontend and my LLM agent shouldn't have to reverse engineer it, it should be an API/CLI easily usable by my agent. I'm a little bit disappointed (and my timelines are correspondingly slower) with how slowly this progression is happening in the industry overall. 99% of products/services still don't have an AI-native CLI yet. 99% of products/services maintain .html/.css docs like I won't immediately look for how to copy paste the whole thing to my agent to get something done. They give you a list of instructions on a webpage to open this or that url and click here or there to do a thing. In 2026. What am I a computer? You do it. Or have my agent do it. So anyway today I am impressed that this random thing took 1 hour (it would have been ~10 hours 2 years ago). But what excites me more is thinking through how this really should have been 1 minute tops. What has to be in place so that it would be 1 minute? So that I could simply say "Hi can you help me track my cardio over the next 8 weeks", and after a very brief Q&A the app would be up. The AI would already have a lot personal context, it would gather the extra needed data, it would reference and search related skill libraries, and maintain all my little apps/automations. TLDR the "app store" of a set of discrete apps that you choose from is an increasingly outdated concept all by itself. The future are services of AI-native sensors & actuators orchestrated via LLM glue into highly custom, ephemeral apps. It's just not here yet.
