This is largely theoretical but still. Smart programming languages have bignum integers and seamless promotion between fixnum and bignum versions. Thus they avoid the issue completely, no stupid casts (especially casts which change both sig

In fact existence of off64_t proves off_t is not OK.
93.
by adobriyan 15y ago
You didn't understand. Consistent use of one (unsigned) type for lengths would avoid issues because there'd be no casts. off_t is signed and doesn't make sense because file length can't be negative.

Lengths should always be unsigned. Always. I'd even say they should always be uintmax_t in C.

Unix pipes are about octet streams not strings.

I'd say there is nothing complex in correct mathematical definition of O() to warrant simplifying it.

OP intends to measure time to read data from file and maybe it process into internal representation. cat(1) almost certainly internally buffers data (32KB here) thus context switches occurs. Shell creates pipe which is buffered inside kerne

like using `gettimeofday()` and not using cat(1), for starters.

case JSON_INTEGER: obj = QOBJECT(qint_from_int(strtoll(token_get_value(token), NULL, 10))); Why is it so hard to parse integer from string correctly?

I largely share sqrt17's grief. There is no such thing as "UTF-32 character". Abstract character is not code point. UTF-32 _is_ fixed width because it's defined on code points, not glyphs, not characters.

And thus forces programmer to think about the order of non-commutative operations.

We're discussing anything that can do open(), read, write(), provides files and directories. Do you understand that virtual filesystems do not have problems with inode counts? Dupping a directory means a) hw state is saved on open(), in whi

Regarding speed and knuth argument. At this stage real world examples show that once scale of the state becomes sufficiently large (large number of conntracks on big firewalls), text interface always lose. So, play with toy flat text file i

Why does signedness matter? Addition is XOR which is sign-agnostic. Multiplication has to be done via table lookups to be fast which also makes it sign agnostic. Well, at least for p=2.

It doesn't matter. What matters is that KGB is still called KGB. Our western friends no doubt are going to setup colorful clusterfuck like they did it in Georgia/Ukraine/Egypt/Tunis. Without doubt it will happen if it will pass in Russia.

RE with backreferences is strictly more powerful then RE without them. Implying that PCRE is somehow inferior due to backreferences support is quite fuddy.

You need whole distribution of process time, not just mean for simulation.

Once a problem becomes a non-toy problem, pipelines lose. troff(1) will do all the hyphenation (C or C++ code) in your code. Ironically troff is like TeX, it processes documents.

by adobriyan 15y ago
You're missing the point (intentionally, I suspect).

Try hyphenating a text with "simple pipeline".

Actually this is better that switch (or whatever). Some advanced dispatch code can notice that some tuples are dispatched more often that the rest and can check for them first. Ditto for dict lookup. But this would unexpected for switch cod

This forces programmer to invent dummy names. And Python doesn't support nontrivial lambdas.
