| 17:10 | <@jerith> | Why the hell are people so in love with PHP? |
| 17:12 | <@jerith> | Why in all the complexity classes does PHP use $this as the currect object, but self as the current class? |
| 17:20 | <@ToxicFrog> | The latter I don't find terribly objectionable. |
| 17:23 | <@jerith> | I keep using the wrong one. |
| 17:23 | <@jerith> | Because both 'this' and '$self' are illegal. |
| 17:24 | <@ToxicFrog> | ...oh |
| 17:24 | <@ToxicFrog> | Ok, that is stupid. |
| 17:24 | <@ToxicFrog> | I thought you just forgot the $ from $self. |

| 17:26 | <@jerith> | No. |
| 17:26 | <@jerith> | Also, other language use either self or this. |
| 17:26 | <@jerith> | If you're going to have both, make them interchangeable. |
| 17:28 | <@jerith> | Also, emacs has a particularly crap php mode. |
| 17:29 | <@jerith> | Probably because anyone enlightened enough to use emacs is too enlightened to use PHP... |

| 17:31 | < MyCatVerbs> | jerith: if you say anything about any possible relationship between vim and PHP and any possibly implications that may result from it, I will beat up orphans with your spine. ;) |
| 17:34 | <@jerith> | I found vim had a fairly decent php mode. |
| 17:34 | <@jerith> | But then vim's modes tend to be rather more limited than emacs'. |
| 17:34 | <@jerith> | Essentially just syntax highlighting and some basic indentation. |

| 17:37 | < MyCatVerbs> | Mmmm, fair enough. What else does emacs give you for, say, C? |

| 17:47 | < MyCatVerbs> | AAAAAAAAAAAAAAARRRRGHHH, HATE C SO MUCH! |
| 17:47 | <@ToxicFrog> | ...what's it done now? |
| 17:49 | < MyCatVerbs> | ToxicFrog: line 42, (after preprocessor macros): if (debug) fprintf(stderr,"Expression is \"%s\".\n",expression); |
| 17:49 | < MyCatVerbs> | Outputs: Expression is: "(d*d)+(d*d)" |
| 17:50 | < MyCatVerbs> | Two lines later, after absolutely no manipulations have taken place whatsoever, expression now somehow has acquired the value ")+(d*d)" |
| 17:51 | <@ToxicFrog> | So run it inside gdb and see what' |
| 17:51 | <@ToxicFrog> | s happening. |
| 17:52 | < MyCatVerbs> | ToxicFrog: I am. gdb shows that, for some reason, the pointer being passed to the function that does something with expression is 4 bytes higher than the pointer lying around in the main() loop. (backtrace, yay) |
| 17:53 | < MyCatVerbs> | So, we have, at line 42: expression = 0x804d6e0 "(d*d)+(d*d)" |
| 17:53 | < MyCatVerbs> | Line 43 is nothing more than a call to fprintf(stderr,"Some message.\n"); |

| 17:53 | <@ToxicFrog> | Weird. Pastebin it? |
| 17:54 | < MyCatVerbs> | Somehow, in the function call on line 44 (void diescreamingonbracketmiscount (const char* expression): diescreamingonbracketmiscount(expression); has managed to mutate it unto: expression=0x804d6e4 ")+(d*d)" |
| 17:58 | < MyCatVerbs> | Argh, pastebin si teh fucking slow. |
| 17:59 | < MyCatVerbs> | Here you go. Notice any bugs? http://pastebin.ca/332007 |
| 17:59 | < MyCatVerbs> | I especially love how the pointer somehow advances four spaces without me fucking touching it at any fucking point. |
| 18:02 | | gnolam is now known as gnolam|away |
| 18:04 | <@ToxicFrog> | Have you tried 'watch expression' in gdb? |
| 18:04 | <@ToxicFrog> | ... |
| 18:04 | <@ToxicFrog> | How is expression++ "not touching it"? |
| 18:06 | <@ToxicFrog> | (also, this seems like kind of an odd way to build a parser to begin with) |
| 18:06 | < MyCatVerbs> | ToxicFrog: that's operating on a copy of expression, not th'original. |
| 18:06 | < MyCatVerbs> | ...how else would one go about building a parser? =D |
| 18:07 | < MyCatVerbs> | Oh, good, found the bug. Mental note not to be so obsessively terse in future. >_> |
| 18:08 | <@ToxicFrog> | What was the bug? |
| 18:08 | <@ToxicFrog> | And generally, one would build a parser by lexing, and then parsing, and mismatch detection is a natural side effect of the parse process. |
| 18:09 | <@ToxicFrog> | Rather than a brute-force operation on the entire expression buffer. |
| 18:09 | < MyCatVerbs> | ToxicFrog: meh, I'm lazy. Checking for syntax errors first saved the bother of making a robust parser. |
| 18:10 | < MyCatVerbs> | Except that it is, of course, a false economy. Not making a robust parser gives me ten times as many headaches anyway. =) |
| 18:10 | <@ToxicFrog> | Yes, that was rather my point. |
| 18:11 | < MyCatVerbs> | Bit late to fix it now. Oh well. |
| 18:11 | | * ToxicFrog looks at this code he's written |
| 18:12 | <@ToxicFrog> | fucking C, not having function closures. |
| 18:12 | <@ToxicFrog> | I want to be able to say [[local function G(...) return PGM_getpx(pgm, ...) end]] dammit |
| 18:12 | <@ToxicFrog> | Oh wait, I can #define that |

| 18:33 | <@ToxicFrog> | ... |
| 18:36 | <@Raif> | ... |
| 18:36 | <@Raif> | Frog, you forgot about #define? :P |
| 18:36 | <@Raif> | That's special. :) |
| 18:39 | <@Raif> | I go to work now, where the hairiest, nastiest code I've ever seen lives. #define isn't just a tool, it's also behind every line of code. :P |
| 18:39 | <@Raif> | Cheer. |
| 18:39 | <@Raif> | s/\./s./ |
| 18:39 | < MyCatVerbs> | Raif: #define is how you make your code look line line noise. |

| 18:48 | <@ToxicFrog> | #define is a crutch for languages without lexically scoped function closures~ |

| 18:59 | < MyCatVerbs> | ToxicFrog: #define is a quick and pretty easy FSA-complete algorithm for abbreviating code. |

| 19:33 | <@TheWatcher> | Does anyone know how to increase the bandwidth an X connection will use? I'm sat here waiting for it to update and it's only using 4 or 5k of a line that can transfer 8 to 16 times that |

| 19:50 | < MyCatVerbs> | TheWatcher: you sure it's not, say, a CPU bottleneck on your SSH tunnel? |
| 19:50 | <@TheWatcher> | Nope, not in the slightest |
| 19:53 | <@TheWatcher> | both ends were using virtually no cpu time :/ |
| 19:57 | <@jerith> | TW: what's the latency on the link? |
| 19:57 | <@jerith> | TCP doesn't deal well with long fat pipes. |
| 20:07 | <@ToxicFrog> | X, in my experience, grabs as much bandwidth as the network stack will let it have up, to what it needs. |
| 20:08 | <@ToxicFrog> | Which is often hundreds of kilobytes per second. |
| 20:08 | <@ToxicFrog> | Which, in turn, is why we have NX. |
| 20:08 | <@ToxicFrog> | So I'd guess that this isn't an X issue, but a network issue. |
| 20:17 | < MyCatVerbs> | How's the packet loss on the link? |
