musl is implementing POSIX. POSIX requires those constants to be preprocessor defines. (Generally, musl asssumes the reader is quite familiar with the C and POSIX standards, which makes sense since it's a libc implementation.)

I don't think sqlite uses direct IO -- at least there's no mention of O_DIRECT in the source code

I'm pretty sure the specification of this class predates name-based virtual hosting. After all, that only appeared in 1997, or perhaps late 1996, and it took a couple of years to be standardized. The URL class existed in Java in 1995 :

Those have an escape key, but the VT220 doesn't.

ASCII was designed for typewriters, not video terminals. "×" is the same as "x". "÷" can be made by overstriking ":" and "-". The quotation marks needed to also function as accents, by over

To counter that, they're working on a bootstrap chain that starts with a tiny 500 byte hex editor and ends with a compiler that can build the GNU toolchain.

I don't see how that's materially different. It still amounts to "Stallman thinks it's acceptable to rape a child in certain circumstances."

Insignificant compared to the time needed to load the program from disk :)

Turbo Pascal is old enough that (I think) they probably wanted to keep compatibility with machines that ran MS-DOS but weren't IBM PC-compatible. If that's the case, messing with the timer interrupt would've been a bad idea.

I knew Oracle offered something like that (implemented by grafting the SQLite frontend/VM on top of Berkeley DB). But it'd be really cool to see page-level locking appear in standard SQLite version.

The story I heard was that the trigraphs were added during standardization because ISO 646, the international version of ASCII, did not require the characters [ \ ] { | }. Fun fact: ISO 646 is also the reason that IRC allows these characte

seccomp is such a sad story. In theory seccomp can do a lot more than OpenBSD's pledge. In practice, the OpenBSD devs added pledge support with comparatively little effort to 100s of programs, while seccomp is a constant headache for t

Well, the Italian government agreed to those terms when they bought the certificates. If they didn't like that, they could've gotten them from somewhere else, or maybe set up a CA of their own, governed according to their own poli

Yes, speedruns are humans playing the game live. If preprogrammed inputs or whatever are used, the term TAS (tool-assisted speedrun) is used. Calling a TAS a speedrun would be a faux pas.

I believe they've been optional in every version of HTML. The example document in the HTML+ spec (1993) did not use them: https://www.w3.org/MarkUp/HTMLPlus/htmlplus_7.html The HTML 2.0 spec gives this as its

And to complete the story, I'm guessing that that old struct likely got serialized in the DCE protocol as dword/word/word/bytes, so the struct layout remained unchanged to maintain compatibility, even as the definition o

But the string representation has five fields, not four. There might be an interesting story in tracing the history of GUIDs through the ages... I found some 1987 code dealing with UUIDs here: https://stuff.mit.edu/afs/

I never understood why GUIDs were defined as typedef struct _GUID { DWORD Data1; WORD Data2; WORD Data3; BYTE Data4[8]; } GUID; rather than simply typedef struct _GUID { BYTE Data[16]; } GUID; I get

Richard Hipp explains the techniques he used to optimize SQLite. While this was a presentation at a TCL event, there's nothing in his explanation that's particular to TCL.

That might not actually be enough -- I've seen gmail collapse emails with distinct subject lines. The format was something like "[foo] Password reset" and "[bar] Password reset".

You're talking as if this were a recent change. GNU true --help has existed for about 28 years now (it was introduced in sh-utils 1.7). That's more than half of Unix's existence.

That's disappointing. The Android calculator has an awesome arbitrary precision engine (implemented by Hans Boehm!). https://cacm.acm.org/magazines/2017/8/219594-small-data-comp...

I'd expect char to be signed, because all other integer types are signed by default.
