For the same reason you trust your ISP? It handles all your internet traffic; and depending on where you live, probably has government-mandated back doors, or is willing to cooperate with arbitrary requests from law-enforcement agencies. Th

I've actually messed with Audacity once, extracting the vowels, lengthening them and overlaying, and there is definitely a difference in quality (the length is pretty much the same), it's just that it's very minor to my ear.

To this very day I can't hear the difference between e.g. "sit" and "seat", or "eat" and "it". I can pronounce them no problem, but hearing it? Nope, those two are the same sounds. Well, whatev

Why do you think I think so? I don't. Those effort estimates don't make the slightest sense.

by Joker_vD 11mo ago
What... what are those "development effort estimates"? They seem to assume an average rate of approximately 11 lines of code written per day which seems a bit too low if you ask me. Besides, once a C compiler is written for one pl

Oh, sorry, I thought you were saying that "RISC-V's comparison instructions don't properly handle integer overflow that internally happens when they do the comparisons, i.e. it only has unsigned comparisons".

It's everywhere. Just recently (a couple of months ago) on HN there was a story about an SQLite-but-rewritten-in-Rust [0], how they've discovered some peculiarity in SQLite file format by reading its source code. Except, of course

I just want an editor! Not a "viitor". Not an "emacsitor". Those aren't even words!!! Imagine calling your firm "Commerical Firm". Would this even be allowed?

Another small trick is to use a "reversed" bump allocator, that starts handing out the memory from the end with the larger addresses. Since AST structures are almost always created bottom-up, children before the parents, the root

I suspect it was adopted from a bigger snippet that had support for parsing things like "-abc" as "-a -b -c", etc.

In that different world, Transmeta would actually succeed in the market of x86-compatible CPUs and, perhaps, would even come up with their own 64-bit extension. Itanium would still flop. Or maybe, if the push came to shove, the desktops wou

At the time, a.out existed and COFF and ELF didn't. The switch from STABS to DWARF has also never happened, right?

But the resulting algorithm is just... weird. It operates under the assumption that the elements f.i can be arbitrary e.g. negative or greater than 9 — which they can't. And adopting that assumption allows you to dispense with keepin

That's a lot of manual effort to save just a tiny bit of thinking. The first digit is the largest digit among the first N-1 digits. The second digit is the largest digit to the right of the first digit up to and including the Nth digit

Nope. Function with external linkage are required to have different addresses. MSVC actually breaks this and this means that you can't reliably compare function pointers on MSVC because some different functions may happen to have same

Wait, why does GAS use Intel syntax for ARM instead of AT&T? Or something that looks very much like it: the destination is the first operand, not the last, and there is no "%" prefix for the register names?
