It says that it has four 10 Gb/s USB ports (2 Type A and 2 Type C). It is unknown whether the ports are independent, or some of them or all of them are connected to an internal hub. Even if they were connected to a single CPU port thro

True, but there are as many 64-bit integers as pairs of 32-bit integers. Therefore the fact that relatively few 64-bit numbers are products of 32-bit integers means that a lot of pairs of 32-bit integers give by multiplication the same prod

In a server, you have to worry about the ME only if you also have an Intel Ethernet interface, which is connected to a potentially hostile network. If that is not true, the ME cannot be controlled remotely. The existence of the ME is much m

While I agree with that in principle, it is very worrisome that the prices of personal computers, especially of any personal computer that is not a big desktop, have been increasing continuously. The price of a mini-PC with Intel Panther La

The US government has failed to learn from its own history. 60 years ago the US government had forbidden the export of fast computers to France, with the hope that this sanction will prevent the French from developing thermonuclear bombs. T

It is the same CPU previously used in the overpriced DGX Spark. It has 10 big Cortex-X925 cores, which are competitive with the Intel P-cores and with the AMD Zen cores, plus 10 small Cortex-A725 cores, which are similar in performance with

The method from TFA uses direct evaporation and it produces solid salt instead of liquid brine. The innovation is that this can work as a continuous process, at a high production rate. The traditional method requires waiting a lot of time u

The potable water is the main product and lithium and other minerals are possible byproducts. Assuming 55% extraction efficiency, the amount of lithium that can be produced is around 0.1 grams per ton of potable water. Even by price, the li

The abstract of the article claims that the median value of extra life time was between 8 months and 9 months. Therefore those well above the median might have reached an extra year of life. I agree however that because almost all of them (

For vegans, creatine is among the recommended supplements, because the amount that is produced internally is insufficient for most people, so they need some extra amount in food. (The same is true for a few other substances, e.g. choline, t

Unfortunately, it seems that this just provides an extra year of life or so. Of course this is better than nothing, but it is not a cure. Moreover, the link provided by another poster to an article that discusses the side effects, shows tha

They are indeed a useful error signal, like also infinities or NaNs. Moreover, they are much more benign than infinities or NaNs, which signal bugs that you most likely have to fix. Denormals cause only very small errors, which may be accep

When underflows happen there are 2 possible actions on any standard processor, which are selected by a bit in a configuration register. One option is to throw an exception. In that case a program will never generate any denormals. Denormals

If you compute a limit numerically, the decision that you have reached the limit must normally be taken long before there is any possibility of underflow, i.e. of generating denormals. Typically you compute the difference between 2 adjacent

The IEEE floats do not have any serious design issue. They are much better than any other floating-point formats that have ever been used. There have been many examples of badly designed floating-point numbers, e.g. those used by the IBM ma

Denormals are not needed if you are willing to handle underflow exceptions. Before Intel 8087 and the IEEE 754 standard, any decent floating-point unit generated overflow exceptions and underflow exceptions, which had to be handled by the p

The simulators for running old operating systems must simulate correctly the entire IBM PC, with all its peripherals, not only the CPU. QEMU simulates some peripherals, e.g. a certain video card, for which it hopes that any operating system

Because this is a library, it presumably allocates nothing in the heap or in static storage. All data must be allocated in the program invoking procedures from the library, and passed as actual parameters. You are right about the .text size

The myth that the original Mackintosh was not intended to have a graphic display with a pointing device is debunked in TFA. The only technical detail that we know about the original Mackintosh that was a mistake was the choice of the MC6809

Jef wanted a trackball instead of a mouse. The claim that he did not want a pointing device is false. That would have made little difference for a Mackintosh user. The hardware of a trackball is exactly equivalent with that of a mouse, neit
