It doesn't take zero transistors, at the very least you will need a multiplexer to choose between the two encodings. But such a mux is less than 10 transistors per bit, a rounding error for any modern CPU.

Windows and Linux run on the same x86 CPU architecture, you don't need to recompile anything. What WINE does is to translate/replace system calls and libraries.

"Diecisiete", still big endian. (you could make an argument for numbers between 11 and 15 though) Yeah, I know there are exceptions, but on average most human languages are big endian.

How do you read a number like 1234? "One thousand two hundreds thirty four", big endian. Most (all?) Western languages say out their numbers in big endian, as do East Asian languages like Chinese, Japanese and Korean. It is only n

Is Raptor still relevant? Looking at their website ( https://www.raptorcs.com/ ) they announce such novel technologies as PCIe 4.0 and DDR 4, and POWER 9 which was released in 2017 while IBM is already on POWER 11.

We bought a sodium battery for our last trip, and it turns out that most airline companies don't even know what sodium batteries are and don't have any provision in their regulations, they are as restricted as lithium batteries :(

How so? There are several recent Steam releases (Demons of Asteborg, Astebros, Earthion) that are just a Megadrive ROM wrapped in an emulator.

I am currently living in Japan, and it seems that they follow the American style exams. I don't know if it is a result of the post-war occupation, or it was already like that before WW2. Back home in Spain we follow the same style of a

That's quite impressive. 70% is obviously way too big for a MiSTer core, but I wonder if one day we will have an affordable FPGA board able to simulate a late '90s PC...

If your goal is just to store the coordinates in a database, sure, use fixed point or whatever. But any kind of calculation will involve a great deal of trigonometry, square roots, and the like. It is just easier to use floating point. Exam

It depends on your use case. Storing WGS84 coordinates as 32-bit floats can incur on errors of several meters. It might be good for your fitness tracking application, but not for serious GIS usage. Case in point: many years ago I was workin

I live in Japan and IMHO the problem is that it is an extremely conservative and risk averse country, "if it ain't broke don't fix it" taken to the extreme. They had a period of innovation after WW2 out of necessity, but

Consoles used off-the-shelf CPUs until the 6th generation. Even the Dreamcast and the first Xbox used off-the-shelf CPUs, it was only the PS2 and the GameCube that started the trend of using custom-made CPUs.

It's funny that you mention Japan, because I live here and I swear 90% of Japanese movies/dramas/animes are just rehashes of the same ideas over and over again. I guess only the good stuff gets exported.

Not everybody wants to live there; heck, I know plenty of Americans that after living abroad in Europe and Japan don't want to go back. And before you say that the US gets a bazillion immigrants per year, Europe gets many more.

The 32-bit ARM architecture included a barrel shifter as part of its basic design, as in every instruction had a shift field. If a CPU built in 1985 with a grand total of 26 000 transistors could afford it, I am pretty sure that anything bu
