for me, the action IS the juice
holy fuck, a hair dryer at a Paris airport broke Polymarket weather markets & made someone $34,000 richer - polymarket was settling Paris temperature bets on a single Météo France sensor sitting near the Charles de Gaulle runway perimeter - basically unguarded - the guy bought the long-shot outcome (like "22°C" when everyone expected 18°C) for pennies, since nobody thought it'd hit - then he walked up to the probe and briefly heated the air around it with a portable heat source, spiking the reading just long enough to register as the daily max - temperature snapped back to normal in minutes, the market resolved in his favor, and he cashed out - twice, on April 6 and April 15, before Météo France caught on and filed charges hyperstitions.

Startups, SOC 👏🏻 2 👏🏻 is 👏🏻 not 👏🏻 a 👏🏻 cybersecurity 👏🏻 standard Is getting a SOC 2 annoying? Yes. Do too many startups get one too early? Yes. Is it bad that ent procurement frequently creates pressure for performative compliance by small companies that don’t have the need or capacity to implement meaningful controls? Yes. Is it “fake security”? No. It’s just solving for something you don’t understand and probably don’t care about… but if your company lives long enough, it’ll become clear why some people do.

A document so explosive that you can’t even talk about how to talk about it without catastrophic national security concerns would be a great background detail in a Pynchon novel.
Exclusive: A U.S. official has alleged wrongdoing by U.S. spy chief Tulsi Gabbard in a complaint that is so highly classified it has sparked months of wrangling over how to share it with Congress, according to people familiar with the matter on.wsj.com/45Mx1aO

New piece attempting to synthesize the past few weeks across media, market structure, geopolitical trust, and lessons from history, asking... can you run the world like a reality TV show? What does it look like to exit the Great Moderation, a 40-year period of macroeconomic stability? Are we in the Great Entertainment? What does that mean for the bond market, the Fed, Japan, and AI hype vs. energy reality?

We're donating MCP to the @linuxfoundation and launching the Agentic AI Foundation with @OpenAI, @blocks, @AWS, @Bloomberg, @Cloudflare, @Google, and @Microsoft. MCP went from internal project to industry standard in a year. Now it gets the long-term stewardship it deserves.

“The jury determined that the launching of the 12-inch deli sandwich from what the government described as “point-blank range” was not an attempt to cause bodily injury, preventing a conviction.”

in some nice ways startups are much easier than 15 years ago in the most important ways they are much harder PMF is a continuous process, not a milestone incumbents are hungrier and better at execution never been more important to keep your head right

There’s this notion that product market fit is this binary condition that once you pass the gate, you’re done. And that’s no longer the case. Product market fit is like United Miles. You continue to fly to maintain 1K. And we saw it between 2021 and 2024, companies that were classic software companies literally overnight lost their product market fit. And that’ll be very much the case. AI is changing what the market wants & what’s possible so quickly that PMF is no longer static. I discussed this idea on TBPN with John & Jordi. youtube.com/watch?v=_0SJe7GX… I remember reading Steve Blank’s The Four Steps to the Epiphany in 2005. It established the idea of product-market fit. The magical moment customers pull your product into the market, & the playbook by which to develop it. In the previous era, once PMF was established, it was taken for granted that it would continue. The underlying technologies advanced incrementally. AI models & their capabilities evolve so quickly today that product market fit must be constantly re-established. Polymarket predicts Google will have the best AI model at the end of the year. At the beginning of 2024, Google was far behind. The most advanced companies in AI are still jockeying for position & so are startups. This is one reason for the boom in deployed engineers—teams need people working directly with customers to understand these dynamics in real time. The velocity of change demands constant feedback loops. Product-market fit is not a one-time event. As the technology changes rapidly underneath, so must your product. tomtunguz.com/product-market…

Until ~2015, GitHub Pages hosted over 2 million websites on 2 servers with a multi-million-line nginx.conf, edited and reloaded per deploy. This worked incredibly well, with github.io ranking as the 140th most visited domain on the web at the time.

RL on synthetic coding tasks with verifiable rewards isn’t RL for production quality software, unfortunately, where the rewards are mostly non-verifiable and involve not screaming profanity at 2am
I don't know what labs are doing to these poor LLMs during RL but they are mortally terrified of exceptions, in any infinitesimally likely case. Exceptions are a normal part of life and healthy dev process. Sign my LLM welfare petition for improved rewards in cases of exceptions.
