All I'm interested in is whether it can be cloud free or not. DIY Wifi addition obviously can, but not so sure of the alternative.

So, a very useful and versatile instruction. Glad AArch64 got it.

I'd like 100 gigabit ethernet, 128 GB ECC, 4x NVMe and still enough PCIe lanes for some GPU for ML. Seems to be impossible without going to server mainboards.

100gbe is already pretty affordable, like Mikrotik's switch. Not an overkill considering a single consumer NVMe drive cam do ~50 Gbit/s. One 100G QSFP28 module costs about $100. 100g Mikrotik CRS504-4XQ-IN switch costs about 600

Can't see it right now (Cloudflare error), so could you expand a bit, please? Edit: Ok, I found an earlier discussion on HN: https://news.ycombinator.com/item?id=33907982 "Rasperry Pi hires former police surveilla

At least when I did a firmware update algorithm, the first step was to checksum existing firmware on the device in blocks. Then I just tried to only update blocks with an incorrect checksum. This effectively implemented a resume feature.

Memory mappable PSRAM support would be nice. Or more pins and more PIO as well. I guess more SRAM wouldn't hurt either.

Great work indeed. Although I do wish Box64 could support statically compiled binaries as well.

It's often about memory bandwidth nowadays. That and locality of reference, random access is expensive. You can compute a ton for the cost of one random memory access.

Hieroglyphs or not, with some human cleverness you can achieve pretty amazing performance. It's not that bad if you just study it a bit and put your mind into it. Just a sequence of relatively simple operations (+ masking when you need

Tesla sold 1,247,146 cars in 2022. This year somewhere between 1.6M - 2.0M. Last year BMW sold about 2.4M cars, so Tesla is quickly catching up in terms of numbers.

Normally operating system simply maps binaries, executables and loadable libraries (.dylib, .so, .dll, etc.) into memory. The cost is approximately same whether you do this once or 1000 times. The code is executed from the mapped area as-is

UPX only means smaller files on the disk, but it comes with a cost: it tends to increase memory requirements, because the binary on the disk cannot be mapped to memory anymore. Unless it's uncompressed somewhere in the filesystem. Wo

Wifi 6 routers such as Asus RT-AX56U etc. were released back in 2019.

Probably they want to share files or to install extra software on the router?

Wifi 6 has been around for about 4 years. Maybe you meant Wifi 7?

"MS often introduces breaking changes in the Windows API" Can you give an example? I have also plenty of Windows development experience, but can't think of anything. More like, Microsoft seems to be pretty careful making sure

Embedded stuff. For example MSP430 has 16-bit ints.

Windows ARM64 runs x86 binaries pretty well. Well enough that it doesn't matter that much you don't have a native Google Chrome, for instance. AMD64/x86-64 version runs just fine.

Pico is more than capable of handling timing within a few hundred nanoseconds with it's PIO (programmable IO) functionality. You don't usually ever need to bitbang with RP2040.

At some point dramatically lower demand will start to push the gas price higher.

11.9% is a pretty huge percentage. If it were like 0.1%, I might agree with you. Imagine you were tight on money and then think about your grocery store bill. Wouldn't you try to save in all categories, even though, say meat, was &quot
