    How does that invalidate the "compression is prediction"? If the future data is different and you failed to generalize, then the failure to predict means you got worse at compressi…

    Weather can be arbitrarily extreme, but: 1. My whole house AC only consumes 3 kW when the outside is really hot, like 36 degrees C, and I seriously doubt that car AC can consume 5 …

    Possible, but EVs tend to be more efficient in city driving than highway driving, thanks to regenerative braking and the fact that the dominant form of energy loss, air resistance,…

    The Waymo I-Pace is much less efficient than the regular roadgoing I-Pace. One X user posted a pic of the dashboard of a Waymo with 111,000 miles on the odometer, and it averaged 1…

    Tesla Cybercab has about three or four times the efficiency and like a fifth of the price by having smaller, two person vehicles. Indeed, the vast majority of trips are taken by si…

    Yup I linked that in my other comment but copy-pasted here for everyone's convenience: The counterexample of the Dinitz-Garg-Goemans conjecture was basically just "keep going" and …

    The counterexample of the Dinitz-Garg-Goemans conjecture was basically just "keep going" and finally "enough of partial results. now finish with a complete unconditional counterexa…

    The article talks a lot about how China makes most of the electric cars and Mexico wants to "capture a piece of the action", but the Olinia has substantial amounts of its engineeri…

    Foreign media like the BBC were actually caught applying a yellow filter to footage of China [1] [2] so maybe they trained on that lol [1] https://www.globaltimes.cn/page/202102/12…

    Thanks. I like low profile mechanical keyboards in theory but I guess I'll just stick to the Keychrons and Lofrees.

    Many ISPs block .cc domains. Especially when .co.cc was a free domain name thing and tons of malware would use it.

    Teenage Engineering makes a lot of products that are basically just a grid of buttons and knobs. It's an obvious comparison to make, even if you disagree on the style/soul etc. Lik…

    You could probably easily get Codex (CLI) to vibe code Linux support tbh. It's probably just a regular USB HID device. The main problem is that right now it only works with the GUI…

    What's wrong with it? I believe you but I'm just curious... since on paper it just uses Gateron low profile switches which seems reasonable.

    Regarding the going "up and down", Starlink satellites orbit at about 500 km above the Earth's surface compared to the Earth's radius of 6400 km. For longer distances it will still…

    Starlink satellites are intentionally designed to be very dark, but they become more visible when the sun is about to come up or if there are super bright light sources on the grou…

    One cool thing about Starlink is that it can potentially improve latency across the world. In optical fibers the light travels only two thirds as fast due to the index of refractio…

    Interesting timing to release this just when SWE-1.7 and Grok 4.5 came out being much cheaper than GPT-5.5.

    Why does usajobs.gov have an autoplaying sound?? I opened this link during a meeting by accident.

    You can also run Qwen 3.6 27B dense model on DGX Spark with comparable performance [1][2] for about $4000 (Asus Ascent GX10 is $3999 at various retailers). In theory you can also g…
