At this point, C and C++ are not compatible. Please stop with this "Oh, just compile C with a C++ compiler." That ship has sailed over twenty years ago with C99. One major difference is designated initializers, which works di

It depends upon the manufacturer. Motorola used PC (program counter), Intel used IP (instruction pointer). I think it's only the x86 that has multiple names, depending upon the size: IP for 16 bits, EIP for 32 bits, RIP for 64 bits.

As the author of org.conman.cbor, I'd be interested in seeing the test data. The only bit that's in C is the low-level bit packing of CBOR values. I might have to revisit the use of LPEG to validate the UTF-8 strings (used becau

I've seen it stated as, "It is a bit of received computer science wisdom that any program has at least one superfluous line and at least one bug. Apply this rule recursively and you can see that any program can be reduced to a

Turns out that mmap() is the memory allocator, nothing to do with files.

I do know how to answer most of the questions. The program is a gopher server. The list you see is the result of sending several hundred (sequential) requests to the server. The number of calls to open() vs. close() can be explained [1],

Because they were all done sequentially, not concurrently.

In 35 years of using Unix I've never come across anything like this. What tool do you use that this is an issue?

I knew some acquaintances back in the day (late 80s/early 90s) who had a company selling X servers. It wasn't a big operation (maybe half a dozen people total) and it worked out of a small office in the industrial section of Ft.

Most Perl code now a days runs under Perl5. I once tried running a Perl4 script in Perl5 and did not have a good day.

I checked the logs for May for one website I run---65% of failed requests were for PHP scripts (mostly Wordpress). I don't run PHP so I don't worry. The rest of the requests were bots that can't parse HTML [1] and other wei

I use the "right-to-left" style myself. To me, the qualifier (in this case, const), applies to the item to the right. This could be confusing: const char *const ptr; The first const applies to the char, but the second o

1. I agree. 2. This would be Gemini. Most people here don't like it either. Also, most gopher sites I visit use UTF-8, and my client (which I wrote---it's not hard) hasn't had an issue with mojibake. 3. It's not as sim

Yes, I mean slide rules. It's a bad habit I have. And yes, the one slide rule I have is the same model as the ones used by NASA astronauts.

I have four side rulers, all of them I bought at antique stores. One of them, the Pickett N600, was used by the Apollo astronauts (it's small---6in (15cm) long, made from aluminum, and very nice). I think I paid about $10-15 for each

That's not the fault of JavaScript, but of IEEE-754 floating point math. The behavior you're seeing is per design.

It was printed in 1994. Linux and BSD (either FreeBSD or 386BSD, I can't recall which) where around, but Open Source (TM) as we now know it wasn't. Other, proprietary Unix systems were still viable and in use (AIX, IRIX, SunOS&#

Not really. It was mostly about tests. Officially, I was a developer for the team (longest one on the team). Unofficially I was QA, as our new manager shut out QA entirely [1] and I became the "go-to" person for tests. Never a
