I kind of knew where this was going in terms of the actual bug, but the way they've "proven" their fix is indeed pretty neat. I would have thoroughly explained the bug and fix, but in order to actually verify I honestly most

I once built an S/PDIF interface on an FPGA for a personal project. It was then that I really, truly understood how much invaluable information is buried in archive.org. Lots of text heavy websites, some more than 10 or even 20 years o

Agreed. I guess "when" just reads a little bit better (english-wise), then.

The “&&” one is super confusing indeed, but the “if” one is just a question of style. It would be possible to reuse the “if” keyword for different grammar. python does it for its trinary operator, where there is an expression instea

The “&&” one is bizarre, it makes it look like the whole thing is a Boolean expression, which it absolutely is not. That gets even weirder because the part right of it actually is a Boolean expression, so on top of very confusing re

That in turn implies that there always is interesting work in startups, doesn't it? On the flip side, there is "interesting work" that only happens in large companies. If you want to orient yourself towards that, you have to

Thanks, that's great context. Do I read it right that the NTSC Apple II generated "artifact colors" (heard that before, but did not know if it applies to the Apple II) through effectively monochrome pixels that just work out
853.
by anyfoo 4y ago
That's more or less equivalent to reading out the RGB values of the colors[1]. As far as I know (never had one), the Apple II's output was composite NTSC, so what colors the values actually correspond to is also standardized. Of c

The very premise is bad. You want to use Rust precisely so that you can write Rust code . The selling point of Rust and most other languages is that they provide a sane, safe, convenient, easy... (pick some of them) interface to the progra

That's what Rust, C, and many other languages are. "Meta languages" that ultimately compile into any number of machine language dialects.

Does the differing prefetch queue size between 8088 and 8086 lead to any significant differences between the Bus Interface Units (or wherever that affects most) of the two chips, or is it basically just a "parameter" in the design

You're right. I meant they are each standing in their own reference frame, so effectively they are moving with reference to each other, but I guess that wasn't entirely clear. For example: One observer is on Earth, the other on an
