This may be legally challenging if you’re not allowed to communicate company internal information and especially files outside of company hardware.

Plus the internet basically equates cynicism with intelligence

This is a generally known phenomenon in psychology. If you leave a book review saying that you liked a book, people are biased to believe you are stupid. If you criticize a book negatively people are biased to believe you are smart.

Ironically the C++ standards consortium doesn’t want C to improve anymore and wants people to just use C++. Rules for thee but not for me.

I can corroborate this. I coached mechanical engineers who had to learn some programming to conduct research by analyzing factory machine data I provided them (them being the domain experts). The ones who learned python and sql using AI hardly had learned anything after half a year, the ones I instructed where to find the API docs and a beginner tutorial weren’t just much further along, they were also on a faster trajectory for the future. I think AI is a beginner trap because it allows them to throw shit at the wall and see what sticks. It is much more useful in the hands of an expert in the long term.

This doesn’t make sense. BSP is a form of culling.

New comment by eska in "“Collaboration” is bullshit"

eska — Wed, 25 Mar 2026 11:49:20 +0000

I don’t think that the author considers collaboration bad in general, but instead how it’s done in most large corporations:

But there’s a huge difference between communication and collaboration as infrastructure to support individual, high-agency ownership, and communication and collaboration as the primary activity of an organisation. Which, if we’re honest, is what most collaboration-first cultures have actually built.

Now, don't get me wrong. Trigonometry is convenient and necessary for data input and for feeding the larger algorithm.

The compiler is often not allowed to rearrange such operations due to a change in intermediate results. So one would have to activate something like fastmath for this code, but that’s probably not desired for all code, so one has to introduce a small library, and so on. Debug builds may be using different compilation flags, and suddenly performance can become terrible while debugging. Performance can also tank because a new compiler version optimizes differently, etc. So in general I don’t think this advice is true.

The problem with Horner’s scheme is that it creates a long chain of data dependencies, instead of making full use of all execution units. Usually you’d want more of a binary tree than a chain.

New comment by eska in "Intermittent fasting may make little difference to weight loss, review finds"

eska — Mon, 16 Feb 2026 18:48:17 +0000

Most of the studies they looked at did not use the most robust methods and included small numbers of people, making it difficult to work out the true effects.

Not a good sign for a meta study. When you average garbage you still get garbage.

As for my personal experience, I looked at scientific papers 5 years ago (no, intermittent fasting isn’t some new social media fad). The consensus back then was that it only slightly increases the speed at which one loses weight, but it helps significantly with adherence to a diet. This was a game changer for me too. With just attempts to control my caloric deficit I failed because I ended up snacking. With intermittent fasting (the strict variant of only eating once after work in my case) I simply had no appetite from the morning until my meal. I also didn’t have cravings before sleep.

Discord had a scandal not too long ago where pictures of people/passports were stolen. There they said that they delete those files immediately after processing them. This proves your statement as false.

Surely there is so much money to be made selling random people's faces.

I really hope I misread sarcasm in that statement. Because of course there is a lot of money in that

Your mental model of integer vs double performance sounds outdated by decades. I’d suggest reading up on instruction performance on agnerfog, should be eye opening.

It is. Takes me back to asking valve about this for my bachelor thesis 15 years ago and getting a personal reply from Gabe Newell who CC’d the developer who came up with the formula, him being all giggly whether I also want to know about skeletal animation that he came up with or the lip sync stuff. Fun guys

If all of your dependencies need to use the same build system as your project then your build system/process is defect anyway. It should be possible to invoke a foreign build system as part of your build.
