Everything has overhead and the only way to control it is to have options that fit your proposed work load and then optimize based on empirical evidence. If however your only option is the callback, then you have no way to work around its

Even though it's GPL you should still read the code. It's very well written and educational. If GPL means you refuse to even read the code then I'm sad for you.

Ryan has a vested interest in not having people adopt coroutines since they show that his stupid "events with callbacks are faster and easier than threads" is bullshit. The truth is if you have coroutines (and these are really easy in unix

I moved to SF from NYC, and NYC was way safer by comparison. I used to work for the NYC Dept. of Correction crunching the numbers on arrests and inmates and I can tell you this is the biggest difference between the two cities: NYC -- The

Just for the record, I am as sick of this part of the book showing up on HN as everyone else. I do not post it here, other people do, and I apologize in advance for it showing up here all the time half-finished. But, if you have a problem

Funny because I actually solve it no problem by using that wonderful technology called a for-loop, which does terminate. So it's only a halting problem when you use K&R's code.

Mastering Regular Expressions is the book you're thinking of.

by zedshaw 15y ago
No, you're wrong still. NL/EOL doesn't factor into it at all. You also are one of those people who thinks the following: 1. "I have been bit in the past by not knowing an obscure fact." 2. "To protect myself, I must learn every obscure fact

I don't consider that a failing of regular expressions (which predate perl), but a failure of implementation. I've thought that instead of syntax it should be an API option that says "this is a matcher" vs. "this is a capture". Then the sa

by zedshaw 15y ago
Yeah, so I thought about making the 2nd half a walk through building a regex engine by first building a lexer, then a parser, then the engine, but I wasn't sure if that'd work to teach regular expression. I think it'd be a great way to rea

by zedshaw 15y ago
I already told you that your reason it was busted is wrong. It's not because of NL or EOL, it's because of the order of precedence of the | operator. If you're going to correct me, be right. In fact, someone also posted a solution in the

Regex aren't difficult to learn, it's just nobody teaches them as a language with a base syntax and words to use. If you just sit down and memorize the names of a few symbols, then learn what each does, then it becomes fairly clear. It's m
253.
by zedshaw 15y ago
I tried to keep it generic, so most of the regex in the book will work in Perl, Ruby, Python, and the libraries since they all originate from Perl's ideas of PCRE. The choice of using Python was mostly because people had read my other book

Nope, the tl;dr didn't miss a thing.

No, it is true. People learn to code from absolutely nothing all the time with my books. Depending on their motivation they then go on to make all kinds of stuff.

Everyone who's for anonymity or pseudo-anonymity wants an all-or-nothing solution where they are totally hidden. The people who propose making everyone known want everyone to totally put all their information online with no protections. Wh

Wrong. I'd defend his right to say it if he weren't anonymous. In the US you do not have a right to anonymous speech. In most countries you don't have this right. You can mostly say whatever you want in public because the people around

You can prove it had an effect on the employees that worked there, and to a fairly exact number. The agreement covered all employees, not just tech workers. Combined that makes up about 350k employees, and you can then extrapolate how m

Yes, most of my crashes on the mongrel2 server I run come from ZeroMQ too. They fix them when I find them, but I actually run my servers under valgrind continually so I can catch them and report them.

Hey, just a quick reply, that, yes I'm rather busy right now but I still squeeze in time for Mongrel2 and should be getting out a 1.8 beta soon.

Right. Developers getting paid. You hear that sound? Listen real carefully. It's the sound of our profession being flushed down a toilet because your buddies are cheating businesses out of their money by charging too much for too little.

No, it's defective and buggy. You can't prove logically that the while loop inside will end given any random input. An implementation with a length will end given any input. That is a bug. If you wrote code like that then I'd flag it

Excellent critique, but you show your hand here: > K&R is an excellent reference, and LCTHW covers some new topics like valgrind, which is great. Wrong, I already demonstrate that they have an example that is basically strcpy() and
