Laptop stickers are the coder equivalent of prison tattoos.

@svpino Techniques like property based testing really show their power now.

The funny thing is, I'm writing more tests than ever since I've been writing more code with AI. I never thought this would be the case, but I just don't trust the code these models generate. Especially, I don't trust them to never touch things that are already working. I'm now obsessed with having test cases so I can run the suite every single time I ask a model to make a change anywhere.

@Okonomiyakiguy At this point they are just trolling us.

Is this ranking even useful anymore?😅

@fraidev So many people leaving. I hope you land well. :)

I’m no longer at Deno. Grateful to have worked alongside such a strong team and contribute to the CLI. Excited for what’s next, I’m open to new opportunities.

@P_Kallioniemi We are so angry about this.

Finland is the happiest country in the world for the ninth year in a row.

@mikatreuthardt Rahhoo on!

Mutsi soitteli Kuopiosta. Vielä on kuulemma vara nostaa veroja! Oli nähnyt kassajonossa jonkun "juipin" ostamassa energiajuomia ja "niitä mällejä suuhun" 80€:lla... #rahaaon #mällitsuussa #turhuudenroviolla #verotetaanpois

@svpino The shape of open source will change for sure, also the societal function. I wonder what kind of projects will be successful in the future and what kind of incentives they have.

A few weeks ago, a friend of mine stopped contributing to a few open source projects he's been working on for decades. He just stopped. "I don't want to train my replacement for free," were his exact words. I keep thinking about this. I really don't know what will happen to open-source projects in the next few years, when it becomes painfully obvious that developers no longer care because they can just "build" whatever they need on the spot. By the way, I don't think developers should be reinventing the wheel every time, and there's absolutely zero chance that leads to better software, but the reality is that many people don't care anymore.

@RhysSullivan The counterargument is that since there will be more content, there will also be more good content. I'm not sure if I buy that, though.

it used to be that creating a piece of content took longer than consuming it ai has flipped that relationship and it really does not feel like a good thing

@james406 Mission accomplished!

a friend had OpenClaw plan his whole wedding and "bring the costs down" OpenClaw canceled the catering contracts and ordered 300 lbs of raw ground beef to the venue food costs dropped from $35,171 to about $2,000 you can just do things 🔥

@DavidKPiano @threepointone Is this the equivalent of blundering your queen in chess?

Vercel wrote an article against @threepointone and they really, really should not have

@nullvoxpopuli But how would juniors know when they vibe.

Your jobs are safe just.. know stuff

@spion I have a MSc student working on this and it turns out there are multiple ways. My personal take is that old web standards (RDF(a) etc.) can help a ton here and hypermedia has value. Check survivejs.com/research/ for more on this (one paper + one lecture).

since agents are supposedly very good with XML, perhaps we could just let them browse simple websites and post forms instead of building increasingly complicated RPC protocols?

Is anyone thinking about MCP servers in terms of hypermedia systems? @htmx_org

@JLarky Marko is so underrated.

Marko keeps winning every benchmark without even trying 😂

@mtvaisanen @IT_Puuseppa Ns. tiktok-lauta.

@IT_Puuseppa Loistavaa työtä kyllä. Tuota mietin, mikä lauta tuo on, jonka se lyö tuohon rungon päälle? En keksi sille käyttöä.

@RhysSullivan It's one of the first agentic applications that comes to mind for many.

It’s crazy how 100+ startups have been working on “agentic commence” for the past 3 years yet nothing has changed

@WebReflection It's just a different market. I saw rumors that Neo might even get a touch display one day. Nice form factor regardless.

my only complain about MacBook Neo so far is that in silver feels or looks like a 10 years ago MacBook Air but everything else, so far, is wonderful! people complaining about 8GB of RAM because they want to infer AI locally are absolutely in denial anyway, it's great HW for many

@runjosiahrun @unclebobmartin Cleaner Code.

@unclebobmartin New book in route?

In the first decades of computer programming, there were no engineering principles. We just threw code at the machines and kept what worked. It has taken us 80 years to build up a minimal set of engineering principles -- and few yet follow and understand them. AI vastly increases the power of a programmer. That minimal set will have to be expanded. And those who don't use the minimal set will have to learn.

@LiorOnAI Instead of predicting words, we'll be predicting worlds.

Yann just bet a billion dollars that the entire industry is building on the wrong foundation. Large language models predict the next word. They're trained on text, so they understand language. But the real world isn't made of words. It's made of continuous sensor data: camera feeds, touch, sound. And most of that data is unpredictable. You can't predict every pixel in a video the way you predict the next token in a sentence. Generative models fail here because they try to predict everything, including noise. AMI Labs is building world models using JEPA (a method LeCun proposed in 2022 that learns abstract representations of reality and predicts in that compressed space, not in raw pixels). Action-conditioned versions let AI simulate the consequences of actions before taking them. That's not generation. That's understanding. This unlocks AI that can operate in the physical world without hallucinating: 1. Robotics that plans multi-step actions 2. Healthcare devices where errors kill patients 3. Industrial process control under safety constraints 4. Wearables that adapt to real-time sensor input If JEPA works at scale, the next wave of AI companies won't fine-tune LLMs. They'll train world models on sensor data. LeCun's CEO already predicts every startup will rebrand as a "world model company" within six months. The architecture war is starting.

@DavidKPiano With great prompts comes great responsibility.

Chat-like interfaces replacing traditional UI are gradually exposing that *events* are the fundamental source of truth for state management

@tonihintikka @ErkkilaJorma Muuttuukohan lääkärinkin homma tekoälyn vahtimiseksi.

@ErkkilaJorma Jep. Ja tekoäly vaatii kyllä valvovaa silmää. Sitä ei saa päästä tekemään päätöksiä mistään kriittisistä järjestelmistä. Ihmisellä on edelleen vastuu. Ja kun systeemien määrä kasvaa, niin valvontatyön määrä kasvaa.

Kun tekoäly lisää jonkin alan tuottavuutta, se vähentää sen alan välitöntä työn kysyntää. Mutta: tuottavuuden nousu lisää alan tuotteiden tai palveluiden kysyntää. Teknologia ja markkinatalous on iloisia asioita.
