It's worth noting that as far as resource distribution goes, East Side was said to receive more funding per student. Too bad they didn't investigate where this money goes.

Well, they pretty much described what actually happened, which is that VMware wasn't all that confident about their security and panicked when the source appeared. While I too would like the article to poke some fun at VMware's at

I think that doing security audits only when your source code leaks (not even when somebody threatens to leak it) is bad software development, not bad journalism.

Those instructions are treated as "legacy PITA" by CPU vendors and, being complex and harder to implement than simpler ones, aren't implemented as efficiently. The CPUs have lots of duplicated logic to process many instructio

Indeed. While repurposing ESP might be rightfully considered ugly, repurposing EBP is quite common and EBX, ECX, ESI, EDI pretty much are general purpose because nobody has been using them for their fixed functions for two decades.

FST/FLD can store/load full 80 bits if you need such precision. No problem whatsoever.

That's true. I started with 16b and transitions to 32b and 64b were pretty straightforward. It's mostly just registers becoming wider.

by qb45 10y ago
Almost correct. If you want to call C code conforming to the x86-64 SYSV ABI, RSP needs to be aligned to 16 bytes when you execute the call . If the code you generate never calls alien code, 8 byte alignment is enough. Since 8 bytes are oc

Audacious has optional WinAmp-style GUI (with skins being WinAmp 2.x compatible AFAIK) and supports global hotkeys, including a "search and jump to file" popup.

But 1080x1920 is stupidly narrow. On 1440x1920 (4:3) you could place two windows side by side without much effort. It barely becomes possible at 1200 (16:10), though not with the font size I'd be long-term comfortable with.

I was under impression that, at least on gcc, everybody uses -O2 and -O3 is reserved for those who have the patience to verify that their software not only still works correctly, but even actually becomes faster. FWIW, I once tried -O3 on s

I love the WTF potential of this one: Another interesting optimization is to use potentially shared memory locations (on the stack, heap and globals) as scratch storage, if the compiler can prove that they are not accessed in other threads

There are two kinds of laziness: one which makes you visit course website, copy teacher's email and send him some stupid question whose answer is one CTRL+F away on the same website, and another which makes you want to automate respond

You can automate replying with a link to the course webpage ToC. Also, make it absolutely clear that the reply is automatic. Hopefully they'll get the hint. Or heck, just make it a policy that if they haven't received an answer

Yeah, there exist humans who fail the Turing test. Another thing is foreign students and teachers who, even if otherwise competent, quickly get one used to language comparable with machine output. I think I may have been guilty of that at

There was some widely circulated study few years ago which found that most SSD models they tested had problems on power loss. Some even bricked. They didn't publish concrete names, unfortunately. But yeah, I agree it's a bug and s

Part of what you count as firmware bugs may have been cases of data/firmware corruption caused by unexpected power loss.

There is much to exploit if the driver itself is buggy. Theoretically it's possible that between various 8bit/16bit encodings, locales, collations, client/server configuration mismatches somebody could find a creative way to
