The way I understood the 80% is that is the margin on the actual product. 36% is what remains after the “investments” in moonshot projects nobody asked for.

I’ve learned this lesson over the years. It is quite common that users make a screenshot of the error with their phone, and send it on to support with hardly any details. The fact that errors become recognizably different is also an improvement: the user and support staffer can recognize recurring errors, and notice patterns.

It reminds me of facebook. Staff was locked out of the office due to the outage they were supposed to fix.

In a perfect world, there would be a stable version of chrome, that would get fixes, but would crucially not get the new features that introduce new vulnerabilities. Not a fun job, I know, but with today’s coding agents it wouldn’t even be an unreasonable ask.

My favorite USB ethernet adapter is a lowly 100 MBit one that works everywhere without requiring driver downloads.

The nuclear option is to disallow it to store your watch history. You get only a search bar and your subscriptions.

I switched to this. It is less fun, but also less of a timewaste.

For Anthropic, it is valuable that they control the scheduling, so they can move jobs around to use the infa when it is relatively quiet. If you let customers choose the time, a lot of work will start at whole hours.

Might as well plug this recent Criminal Podcast episode: https://thisiscriminal.com/episode-358-the-formula-3-27-2026

TLDL: During prohibition, US government required adding 5% methanol to industrial alcohol, hoping that this would stop bootleggers from selling it as liquor. It was sold anyway, resulting in many deaths.

Both of you are right. There is one more edge case: if you commit to buying electricity in advance it might cost you extra to not consume it. It would still be in your interest to use the power at a net marginal loss rather than not using it and paying a fine for failing the contract.

Is this something you can share in more detail? Did you document a skill for the LLM to use? And with what tasks do you see most improvement?

Patrick Boyle (fund manager, professor, youtuber) recently discussed this IPO on his channel. Informative and entertaining.

About the use of different units: next time you choose a property name in a config file, include the unit in the name. So not “timeout” but “timeoutMinutes”.

That was a very good summary. One detail the post could use is mentioning that 4 or 10 experts invoked where selected from the 512 experts the model has per layer (to give an idea of the savings).

Watched this a few days ago. The video is light on technical details, except maybe that they used CGI to generate training data.

New comment by superjan in "Parallels confirms MacBook Neo can run Windows in a virtual machine"

superjan — Sat, 14 Mar 2026 09:37:30 +0000

On Apple silicon, Parallels can’t run x64 windows, it is using the ARM version of Windows. The x64 emulation is provided by Windows. Of course this is inefficient, but not everything is automatically 2x slower: any OS code you invoke is not running as x64 emulation, and IO and memory access is not penalized by the emulation (but certainly somewhat from virtualization). I was pleasantly surprised how fast you can run x64 windows apps.

New comment by superjan in "NaN Is Weird"

superjan — Thu, 12 Mar 2026 21:06:11 +0000

IEEE 754 prescripes, for better or worse, that any mathematical comparison operator (==, <, > ….) involving at least one NaN must always return false, including comparison against itself. This is annoying for something like dictionaries or hashtables. C# has a solution: if you call a.Equals(b) on two floats a and b, it will return true also if both are NaN. I think this is a cool solution: it keeps the meaning of math operators the same identical with other languages, but you still have sensible behavior for containers. I believe this behavior is copied from Java.
