Of course you can often beat the compiler, humans still vectorize code better. And that interpreter/emulator switch-statement issue I mentioned in the other comment. There are probably a lot of o…

Might be an interpreter or an emulator. That’s where you often want to preserve registers or flags and have jump tables. This is one of the remaining cases where the current compilers optimize rather …

> - mov ax, 0 - needs 4 bytes (66 b8 00 00) - xor ax,ax - needs 3 bytes (66 31 c0) You don't need operand size prefix 0x66 when running 16 bit code in Real Mode. So "mov ax, 0" is 3 …

I have had zero issues running ZFS on Linux for the last 10 years. (Not saying there were no issues that have annoyed or even caused data loss.)

IKEA 45W and 65W Sjoss chargers and braided cables are also good. Pretty cheap too. There's also a 30W charger, but it has cheaper, presumably poorer quality components. Those chargers have nice …

And the industrial base that maintains it? Chips have a limited lifespan.

In case you're not familiar with the metric system: 1m is 1000mm. In other words, one millimeter is one thousandth of a meter.

Here's some more information: https://www.hackster.io/news/ian-scott-s-picoide-turns-a-ras... Based on RP2350. Perhaps because RP2350 provides more GPIO pins?…

> Charging is the problem. Which also occurs while driving, whenever you're decelerating.

Sorry also for being offtopic, but "cracking" in this case most likely refers to cracking [with laughter].

I wish PCs had a unified GPU with 400..1000 GB/s bandwidth to the main memory. Up to 256 GB (or even 512 GB in Mac Studio). It's nice for AI. Thus staying on Macs, at least for now.

Dithering is usually used up to 18-bit color (6 bits each red, green and blue components). But it's useful even past that to reduce banding.
comment
Could you give me some numbers about deaths caused by Tesla versus other brands per mile driven? It seems to be very difficult to find enough information to draw any conclusions.

Not only Cybertruck. Also other trucks like Ford F150 etc.

Special games? I thought NES was controlled by Nintendo?
comment
C++98 forced the compiler to generate a lot of useless code. Newer semantics helps to remove this overhead. You can still write things the old way, if you like.

Vampire is not really a 68k, it's an FPGA based system. A kind of fantasy could-have-been system.
comment
> 160x100 CGA low resolution could do 16 color (bit of a hack, but semi-official). That's a text mode, but ok, I think some games used it for graphics.
comment
I hope these new IKEA light bulbs finally reproduce deep greens. Some cyan shades were also nearly white. Blue and red shades were fine. (Not so coincidentally green shades are always missing from IKE…
comment
320 x 200 CGA allows you to have only 4 colors at a time. Of course you can change the fixed palette on a certain scanline to have more colors. See for example California Games.
comment
Since this is intended for embedded systems, supporting ARM DSP extensions would be beneficial. Correct me if I'm wrong, but I have not seen any compiler generate those instructions, other than t…

Have they already solved the issue of LIDAR destroying CMOS cameras with its laser?
comment
Is there a tool that can dither to named colors?
comment
A side channel attack revealing AES key from just 90,000 traces. Sigh, side channel attacks seem to be everywhere now.
comment
To transfer files? Like large virtual machines, huge video files. Backup their files quickly. To support a homelab to learn new skills. To stream uncompressed video. To download 300 GB monster games. …

Obviously he/she meant 600 Mbps.
comment
I generally agree, although one should not forget x86 (and AMD64) leaves about 3-10% performance on the table due to having a memory model that doesn't allow to reorder loads with other loads and…

Perhaps a Macbook is now fast enough to just run Windows 7 in full emulation? Haven't tried, though. Edit: Checked on Youtube. Yeah, Windows 7 seems to be fast enough on an Apple silicon Macbook …
