CUDA is at reach of anybody with a nvidia GPU, because apart from AI, it is useful for gaming, video streams, graphic works, and other stuff. So teenagers can start playing with CUDA, and developers know that their software requiring CUDA would had a large user base from day zero. Tenstorrent...

The story of computer hardware is full of cases where the engineers didn't got support for their ideas, so they left the company, started their own, and made a revolution. For example Cray left his company to build his own supercomputers, and his ideas are today in all consumer processors. Many...

If you are really desperate, is possible to reclaim space from the master file table. An almost full disk, generally has a large unused part of the master file table. But I don't remember the name of the tool that did it. Also, the windows\winsxs folder uses to waste a lot of gigabytes which...

In the past, there were so many foundries, that when one got stuck, being unable to advance, some other foundry developed a new idea, and beat them, accelerating the advance of the technology. Today the number of foundries is so small and expensive, that new ideas that think out the box got so...

popcount can be emulated, but that would require patching any program that uses it, and it would be slow.

The patches are installed by the OS updates.

Intel security features only work if the OS supports them, and the constant patches by Intel and AMD breaks the OS.

At work, I won the fame of "the dude that repairs computers", so a lot of people asks me to fix their laptops, and the most common problem are broken bootloaders. The security fixes (mostly from Microsoft) don't stop the bootloaders from breaking, and frequently are the cause. But the worst...

According to Tom's Hardware GPU hierarchy, the original gtx titan is a bit weaker than a GeForce GTX 1660.

Multiplication and modulo division are expensive operations. I think Hacker delight had a faster emulated popcount, but I don't remember. Anyways, I use popcount daily, and thought that it was available since the 8086. Can't imagine life without it, or countx_zero.

AVX is unusable, because there is no standard. Each processor has different instructions. New processors do not support older instructions. Even the same CPU doesn't support the same instructions on all cores. Is a hell. The only thing that can be trusted to work is SSE4.2, which is almost 2...

Δ25 Cº means that AMD packaging design is massively incompetent.

At the price of a 4090, it should include all the components necessary for safe operation, without third party pieces.

The most expensive cards in the history, were made with the worst quality.

Of course. That's why they put 3 computers. It was guaranteed that they would fail. Even today, some space computers fail the first day of work. Space is harsh. Here on earth, we are protected from radiation by Earth's magnetic field and atmosphere. That doesn't exist in space. We still don't...
