No. For equivalent quality, even a high-order delta-sigma encoder will need more bits than PCM. The ratio between the sampling frequencies is greater than the ratio between the number of bits per sample. How much greater it is depends on th

I cannot imagine any reason why somebody would want to use RELEASE for production. A RELEASE is good for installing FreeBSD on a new computer, or for upgrading from a previous major version of FreeBSD, e.g. from 13 to 14 or from 14 to 15. A

And various dedicated AI models all made poor predictions of the results of that experiment, which casts doubts about the value of the AlphaGenome predictive map. A virus is much simpler than a human, but even for that simple virus the effe

Depends on what you mean by "efficient". Delta-sigma modulation generates an inefficient encoding of the audio signal, with much more bits than necessary. Converting a delta-sigma encoded bit stream to a PCM (pulse-code modulation

Pangram is wrong. The text does not have any of the superfluous words typical for Claude/OpenAI talk. It is written like an answer to "Explain to me like I am 5", but it contains appropriate information for such a context. On

Most Mali drivers from the kernel are not contributed by Arm, but you are right that nowadays some contributors from Arm have appeared for the older reverse-engineered GPU drivers, like Panfrost and Panthor, and now there are also a few GPU

All the mainline kernel support is reverse-engineered. No help from Arm. Thus there is a considerable lag for the support of newer Mali generations. Some Linux distributions for various embedded computers with Arm-based CPUs and GPUs use cl

As it says at the end, this was evidence at the class action suit "Comes v. Microsoft Corp.", which was eventually settled by Microsoft by paying $180 million, after many years of litigation.

I think so. But developing the heuristics for choosing the appropriate compression algorithm for a stream of data is likely to need a very long time for compression tests of a lot of diverse training data, similarly to the training of a spe

I have not experimented with bzip3 recently, but more than a year ago I have done many tests with it. Initially I was extremely impressed with it, because in a lot of tests it succeeded to compress hard-to-compress files, like movies, and i

As a non-US citizen, what has always astonished me, already while watching a direct TV transmission of all the events of that day, and seeing live the following attacks, was not that the first plane successfully hit its target, because desp

Did you really map it as normal memory? Standard UARTs are accessed in the x86 I/O space, which is uncacheable and strongly ordered, not in the normal memory space. Non-standard UARTs that are on PCIe add-on cards might be mapped into

The original text linked by another poster says "salt as desired". So the quantity of salt is not specified in the original recipe, therefore it could be the same as any present cook would choose.

I partially agree with you, in the sense that any useful custom integrated circuit must include some analog part, otherwise it would not be competitive with standard programmable logic. Nonetheless, having actually worked as an analog IC de

I have stopped using TV sets more than a decade ago. Instead of a TV set, I use a very big monitor, which is connected to a mini-PC (an old Intel NUC with Linux), which also has a TV tuner and an infrared remote control receiver. Besides ju

Short turnaround times does not mean a single day. Even an ancient 1 micron CMOS process requires something like one hundred process steps, many of which may need up to a few hours in an oven. If completely automatized, it could be done in

Yes, only one day of processing is impossible for any kind of integrated circuit. One day of processing would be possible only for semi-custom integrated circuits, like gate arrays, which have already been fabricated until a last step that

Not really. To the front end, one needs to pipe only appropriate logical combinations of the flags that describe the memory properties, not the flags as they are stored in some control register. So a control register should contain flags th

That is exactly what the poster to whom you replied said. So Arm did not add another means to disable this kind of speculative execution, after Spectre was discovered, but they just reused the existing NX flag, expanding its functionality.

To get a sense of how the computer runs your program you need to learn some modern assembly language, i.e. either Intel/AMD x86-64 or Arm Aarch64, or for something simpler one could start with IBM POWER. The hardware machine model used

This has been researched for decades, but progress is very slow. Other wide bandgap semiconductors, i.e. silicon carbide (a.k.a. "moissanite" in jewelry) and gallium nitride are well on their way to make silicon completely obsolet
