Error codes and longjmp are complementary methods of exception handling. Error codes can't handle every circumstance (well, at least not without undue pain). For example, error codes don't deal with nonblocking i/o or corouti

You can't really tell if the stack overflowed in a constructor though, plus that will essentially /never/ happen, so I think it's okay to exclude stack overflows when creating stack allocated objects as failure condition

That's basically everyone's sentiment in the Perl community right now. Perl6 is a nice language (I mean, I'm not a huge fan, but it's not bad either) but it's a language that has some Perl influences but is definite

Intel also has patents on many x86_64 extensions and AMD has patents on x86_64 itself. I believe MMX expired recently, so a Pentium III level CPU could be implemented without infringing on ISA patents. Hitachi still has patents on SH4 (thou

Shor's algorithm covers discrete logarithm also. But most modern asymmetric algorithms are based on elliptic curves and other problems that quantum computers don't help with.

Yikes! NT kernel is far far far better designed than any * nix¹. POSIX is an API (and not a very good one), not a kernel type anyway. Windows has had a POSIX layer for a while. The NT kernel actually has its own API that both the Win32 an

At least these (seem to) result in a kernel panic instead of privileged escalation or reading unauthorized memory. But in a world where even djbdns had a (minor) security issue, I don't think it's reasonable to expect any non-triv

OTOH, it takes a lot longer to become physically dependent on alcohol than opiates. But yes, don't mess with your GABA system unless you like seizures; and don't mess with your opiod system unless you like being miserable.

OCaml already looks nice <_< (…Once you've used it for a bit. I admit it looks kinda weird at first.) I recall Reason didn't yet support some important part of OCaml syntax, but I don't remember what that was. Though I

unwrap panics on failure; try! is equivalent to match somefunc() { Ok(res) => res, Err(e) => return Err(e) } in Rust; or res, err := somefunc() if err != nil { return err } in Go. Also, while I don&#x27

You're right, I got something backwards there! I suppose it's not that unnatural on second thought. Your examples are good, though the only ones that are moderately common in American English seem to be “drawing” and “crossing”.

Do Brits use gerunds other than ‘working’ as nouns or is it specific to that case? Either way, that's really weird.

Alternatively… "LIKE GOOD STUDENTS, COMPUTERS NEED TO BE ABLE TO SHOW THEY'RE WORKING" heh.

by PeCaN 10y ago
I've never seen that before. Using a gerund as a noun seems very unconventional and incorrect almost by definition. Simply ‘work’ reads much better—is it really frequently used as ‘working’ in mathematics‽

You still didn't explain why they need that many people. What exactly _is_ required for “running something at the scale of Vine”? Yes, they have/had a lot of traffic, but traffic in and of itself does not require a large staff t

I particularly like this quote: “[T]he major obstacle is not lack of machine capacity, but our inability to write programs taking full advantage of what we have.” Which is more relevant now than ever. It's interesting that at the time

Azul has their own hardware for facilitating pauseless garbage collection with their JVM. I recall they have a pure software pauseless JVM now as well, but it's not nearly as high performing.

Jane Street isn't an HFT firm, though I do agree that OCaml would be a much better language than Java (though the lack of manual GC tuning could be a dealbreaker).

Or crashing, for that matter. If your C HFT program crashes, someone is on the hook for tens of thousands, minimum . (Not saying Java doesn't crash, but it's a bit more rare and gives you more opportunity to not lose $$$.)

Well… it's honestly because I don't give a shit about LZFSE and Apple can fix their own code. But I could also say that I'm lazy and it's not a big deal anyway.
