Programming makes me happy.

Say goodbye to Dropbox, iCloud, and OneDrive subscriptions. Someone open-sourced a sync tool that replaces all three for $0. And no company can shut it down. It's called Syncthing. Here's how it works: Every cloud storage company on earth routes your files through their own servers. That's not a technical requirement. That's a business model. Syncthing skips the server entirely. → Your devices connect directly to each other → Every transfer is TLS encrypted with perfect forward secrecy → Every device is authenticated by a cryptographic certificate → Nothing moves without your explicit permission → Works on Windows, macOS, Linux, Android, FreeBSD No account. No subscription. No company holding a copy of your files. Dropbox can raise prices. iCloud can change its terms. Google Drive can shut down tomorrow. Syncthing runs on your own machines. There's no server to breach. No company to pressure. No subscription to cancel. One install. Your devices. Your files. Your rules. 100% Opensource. syncthing.net

Looking forward to this. Google’s 100$ price per click for key word “data room” is insane and $500 per conversion isn’t something a bootstrapped early stage startup can afford

This podcast clip was 100% built with Claude. You bring the script and the idea. Claude builds the workflow. One run, raw output ready for post. RT + comment "workflow" and I'll send it to you.

Someone just open-sourced a complete structured Quran database for developers and researchers. 100% Free.

You don't understand how BIG this is. Everyone kept saying RAG is dead. RAG isn't dead. It just couldn't run where it actually matters. Hospitals won't let patient data touch the cloud. Manufacturing plants can't connect to the internet. Defense systems are air-gapped by design. VectorAI DB is the first vector database that runs completely offline. At this point I'm pretty sure this just unlocked an entire category of AI apps that were impossible to build until today.

you don't need to pay for ElevenLabs & WisprFlow subscription anymore. someone just open-sourced BOTH in one app. completely free. runs locally. no API keys. no usage caps. → clone any voice → global dictation hotkey → your agent can talk back → 7 TTS engines → 23 languages here's how to set it up under 5mins: 1/ download mac (apple silicon): voicebox.sh/download/mac-a… mac (intel): voicebox.sh/download/mac-i… windows: voicebox.sh/download/windo… docker: docker compose up open the dmg, drag to applications, launch. 2/ clone your voice (60 sec) → profiles tab → + new profile → name it, pick a language → upload a 10–30s clean audio sample (or record live in-app) → save that’s your voice. reusable across every engine. 3/ generate speech → generate tab → pick your profile → type your text → hit generate first run downloads the model (one-time). after that it’s a few seconds per clip. pro tip: use chatterbox turbo + type / in the box to drop in [laugh] [sigh] [gasp] tags. 4/ give your AI agent your voice this is the part that broke me. voicebox ships with an mcp server. add it to claude code / cursor / cline once, and your agent calls voicebox.speak to talk back in your cloned voice. settings → mcp → copy the snippet into your agent’s config. done. 5/ dictate into anything → settings → dictation → set a global hotkey → hold it anywhere on your system, speak, release → transcript pastes into the focused text field slack, email, code, browser — works everywhere. 6/ that’s it. no api keys. no usage caps. no audio leaving your machine. you just replaced two SaaS subscriptions with a 200mb native app. github.com/jamiepine/voic… follow and turn on post notification for more content that helps you maximize the use of AI.

This took longer to read than it should have, 2 months, big book, takeaways, states and mayors competing works, also needs a variable reward mechanism, winners get bigger states, the more subtle takeaway if you want to change something don't forget to praise your predecessor even if you don't mean it :), people want change but don't like to change... 7.5/10, largely cos of how similar many of the themes are relative to wr the world is today.

Elon Musk avait dit un truc qui m'avait marqué sur l'allocation de ressources. En substance : passé un certain niveau de richesse, l'argent n'est plus de la consommation, c'est de l'allocation de capital. Cette phrase change tout. L'économie, dans le fond, c'est juste un problème d'allocation. Tu as des ressources finies et des usages infinis. Qui décide où va quoi ? Imagine une cour de récré. 100 enfants, des paquets de cartes Pokémon distribués au hasard. Tu laisses faire. Très vite, un ordre émerge. Les bons joueurs accumulent les cartes rares, les collectionneurs trient, les négociateurs trouvent des deals. Personne n'a planifié. Et pourtant chaque carte finit dans les mains de celui qui en tire le plus de valeur. Le système maximise le bonheur total de la cour. C'est ça, la main invisible. Maintenant fais entrer la maîtresse. Elle trouve ça injuste. Léo a 50 cartes, Tom en a 3. Elle confisque, redistribue, impose l'égalité. Trois effets immédiats. Les bons joueurs arrêtent de jouer, à quoi bon. Les mauvais n'ont plus de raison de progresser, ils auront leur part. Les échanges s'effondrent. La cour est égale, et morte. Elle a maximisé l'égalité, elle a détruit le bonheur. Le problème de la maîtresse, c'est qu'elle ne peut pas avoir l'information que la cour avait collectivement. C'est le problème du calcul économique de Mises, formulé en 1920. L'URSS a essayé de le résoudre pendant 70 ans avec le Gosplan. Résultat : pénuries, queues, effondrement. Pas parce que les Soviétiques étaient bêtes, parce que le problème est mathématiquement insoluble en mode centralisé. Quand Musk a 200 milliards, il ne les consomme pas, il les alloue. SpaceX, Starlink, Neuralink, xAI. Chaque dollar est un pari sur le futur. Et lui a un track record. PayPal, Tesla, SpaceX. Il a démontré qu'il sait identifier des problèmes immenses et y allouer des ressources avec un rendement spectaculaire. L'État aussi a un track record. Hôpitaux qui s'effondrent, éducation qui décline, dette qui explose, services publics qui se dégradent malgré des budgets en hausse constante. Le marché identifie les bons allocateurs, la politique identifie les bons communicants. Le profit n'est pas une finalité, c'est un signal. Il dit : tu as alloué des ressources rares vers un usage que les gens valorisent suffisamment pour payer. Plus le profit est gros, plus la création de valeur est grande. Quand Starlink est rentable, ça veut dire que des millions de gens dans des zones rurales ont enfin internet. Quand un ministère est en déficit, ça veut dire qu'il consomme plus qu'il ne produit. L'un crée, l'autre détruit, et on appelle ça redistribution. Dans nos sociétés il y a deux catégories d'acteurs. Les entrepreneurs et les bureaucrates. L'entrepreneur prend un risque personnel pour identifier un problème, mobiliser des ressources, créer une solution. S'il se trompe il perd. S'il a raison, ses clients gagnent, ses employés gagnent, ses fournisseurs gagnent, l'État collecte des impôts. Il est la cellule de base du progrès humain. Le bureaucrate ne prend aucun risque personnel. Son salaire est garanti. Au mieux il maintient une rente existante. Au pire il la détruit par excès de réglementation, mauvaise allocation forcée, incitations perverses qui découragent ceux qui produisent. Mais dans aucun cas il ne crée. Regarde les 50 dernières années. iPhone, internet civil, SpaceX, Tesla, Google, Amazon, Stripe, mRNA, ChatGPT. Toutes des inventions privées, portées par des entrepreneurs, financées par du capital risque. Pas un seul ministère n'a inventé quoi que ce soit qui ait changé ta vie au quotidien. La France est devenue le laboratoire mondial de la dérive bureaucratique. 57% du PIB en dépenses publiques, record absolu. Une administration tentaculaire, une fiscalité qui pénalise la création de richesse. Résultat : décrochage face aux États-Unis, à l'Allemagne, à la Suisse. Fuite des cerveaux. Désindustrialisation. Dette qui explose. Et le pire c'est que la mauvaise allocation s'auto-renforce. Plus l'État prélève, moins les entrepreneurs créent. Moins ils créent, moins il y a de base fiscale. Plus l'État s'endette et taxe. Boucle de rétroaction négative parfaite. La maîtresse pense qu'elle aide, et chaque année la cour produit moins. Dans nos sociétés, ce sont les entrepreneurs, toujours, qui font avancer la civilisation. Les bureaucrates au mieux maintiennent une rente, au pire la détruisent. Aucune société n'a jamais progressé en taxant ses créateurs pour subventionner ses gestionnaires. La question n'est jamais qui a combien. C'est qui alloue le mieux la prochaine unité de ressource pour maximiser le futur de l'humanité. La réponse depuis 200 ans n'a jamais changé. Ce ne sont pas les fonctionnaires.

India doesn't need to lead the world in building the most advanced AI models. But it must lead in ensuring benefits of AI are widely shared. @rvenk and I have an op-ed in The @EconomicTimes economictimes.indiatimes.com/opinion/et-com…

70 years ago in 1955, John von Neumann wrote an epic and prescient essay: “Can We Survive Technology?” … He saw that technology’s spatial reach was catching up with Earth’s actual size, while political organization remained stuck at smaller scales, and that human reaction time is a fixed constant while the technological tempo only accelerates — so each new generation of tools enlarges the unit affected by any single decision until the unit becomes the planet itself! 🌎 From this logic, he drew the conclusion that no procedural firewall, no institutional design, no advance solution can absorb the resulting risk; only ongoing judgment exercised in real time by agents with skin in the game can. sseh.uchicago.edu/doc/von_Neuman…

YC on how to build a company with AI from the ground up:

Bengal is not just Bankim Chandra Chattopadhyay, Vivekananda, Subhash Chandra Bose and Tagore. It is also Raja Rammohan Roy, Vidyasagar, Bimal Roy, Amartya Sen, Mahasweta Devi and Satyajit Ray. Those who mention the former without the latter haven't got their Bengal right. It is a thinking and FEELING community for which life is much bigger than the economics of pomp and vanity.

Modi About Jadavpur University ".......Threats Are Being Issued Inside The Campus, ANTI-NATIONAL Slogans Are Being Scrawled On The Walls..... " Jadavpur University has Hit Back at #Modi this time — and it did so BRUTALLY. "BJP’s policy is to have fewer Jadavpurs across the country and more ‘Galgotias’." "BJP is always a Greater Threat to Bengali Identity." "BJP is always a Greater Threat to Bengali Intellectuals."
