| 01:15 | | * gnolam declares victory over the sun! |
| 01:19 | < gnolam> | (In other words, I now have a sun that travels realistically over the skybox according to the time of day, day of year and latitude and longitude) |
| 01:22 | < gnolam> | Now I just have to add some blooming and lens flares. |
| 01:32 | <@Vornicus> | Pfff. |
| 01:32 | <@Vornicus> | How about shadows? |
| 01:49 | < gnolam> | No shadows. Just Phong lighting. |

| 01:56 | <@Vornicus> | I gotta ask |
| 01:56 | <@Vornicus> | Why do you care? |
| 01:57 | < gnolam> | Because it's generally advisable that the sun /actually sets/ in a time-of-day effects system. :) |
| 01:59 | <@Vornicus> | Well yes, but... |
| 01:59 | <@Vornicus> | I mean, why do you care what direction the sun is coming from? |
| 01:59 | < gnolam> | What do you mean? |
| 02:00 | <@Vornicus> | Well first, why are you implementing time of day anyway/ |
| 02:04 | | Dae [Dae@Nightstar-6bffd408.dial.as9105.com] has joined #code |
| 02:05 | <@Vornicus> | And then, why do you care that it's accurately placed as far as time/day/lat/long go? |
| 02:05 | < gnolam> | Several reasons. 1) It's cool. The only reason you need, really. 2) The project is an outdoor environment (specifically: ocean environment) renderer, and getting the sun right makes an incredible difference in realism. 3) The specification says so. ^-^ |

| 17:57 | | Derakon[work] [Derakon@Nightstar-d44d635e.ucsf.edu] has joined #code |
| 17:57 | < Derakon[work]> | Today I discovered a memory leak on one of the other microscope machines. Maybe that is causing the crashes... |
| 17:58 | < Derakon[work]> | So now I just get to figure out why a (apparently pure-Python this time!) program is leaking memory. |
| 18:00 | <@McMartin> | Circular references. |
| 18:00 | <@McMartin> | Python's pure reference count until it's too late. |
| 18:01 | | * Derakon[work] nods. |
| 18:01 | < Derakon[work]> | I have the added bonus here that the buggy program is one I've not yet looked at. |
| 18:01 | < Derakon[work]> | So I get to figure out how it works while I figure out why it's not working. |
| 18:01 | <@McMartin> | Oh, well, hell |
| 18:01 | <@McMartin> | Unsnapped global arrays. =P |
| 18:02 | < Derakon[work]> | Er? |
| 18:02 | < Derakon[work]> | "Unsnapped"? |
| 18:03 | <@McMartin> | "global array isn't snapping its connections to objects that are supposed to be dead; thus, it never truly becomes garbage." |
| 18:03 | <@McMartin> | Either by assigning None to its elements or to the entire array |
| 18:03 | < Derakon[work]> | Ah. |
| 18:23 | < Derakon[work]> | ...ergh, Sebastian, why do you do this? ;.; |
| 18:23 | | * Derakon[work] discovers that much of the work is done in a compiled C library. |
| 18:23 | < ErikMesoy> | Sebastian? A cow-orker? |
| 18:23 | < Derakon[work]> | Implementor of the project that I'm working on; long-since fled to Germany. |
| 18:25 | < Derakon[work]> | Has a tendency to use opaque variable names, heavily customized build environments, zero comments, and massively obfuscated interdependencies. |
| 18:25 | < gnolam> | And wonderfully descriptive filenames as well, IIRC. |
| 18:26 | < Derakon[work]> | Ah, yes. sebC.py, sebH.py, sebTests.py, etc. |
| 18:30 | < Derakon[work]> | % grep -ri seb *|wc -l |
| 18:30 | < Derakon[work]> | 7949 |
| 18:34 | < gnolam> | In other words, the code is suffering from sebsis. |
| 18:34 | < Derakon[work]> | ... |
| 18:34 | < Derakon[work]> | Yes. |
| 18:35 | < Derakon[work]> | Another thing Sebastian does is fail to understand proper use of whitespace. To wit: |
| 18:35 | < Derakon[work]> | void Reply(int answer) |
| 18:35 | < Derakon[work]> | { write_mailbox(answer, MONITOR_MBOX); } |

| 19:25 | <@AnnoDomini> | I like how Google Translate is shaping up. It automatically recognizes language, and gives translations in English for some words it doesn't know in the target language. |

| 20:36 | <@Derakon[work]> | Whelp, I've tracked down the memory leak to InitProfile(), a 122-line C++ function. |

| 21:12 | <@AnnoDomini> | *infinite |
| 21:12 | <@Derakon[work]> | I've stripped it down to 72 lines by removing commented-out code and a rather large block surrounded by "if(0)" |
| 21:12 | <@Derakon[work]> | Anno: yes, I'm aware of the typo. It's part of the reason I pasted it. |
| 21:16 | < ErikMesoy> | "if(0)" ?? |
| 21:16 | <@Derakon[work]> | if (0) { stuff you don't want executed but still want around for some reason} |
| 21:16 | <@Derakon[work]> | Generally done via #if 0, since that way the code doesn't make it into your compiler. |
| 21:16 | < ErikMesoy> | So it's like obfuscated commenting out? |
| 21:17 | <@Derakon[work]> | Kinda, yeah. |
| 21:17 | <@McMartin> | It's like commenting out that lets you have comments in what you're commenting out. |
| 21:17 | <@McMartin> | Since you can't use /* */ |
| 21:17 | <@McMartin> | Since those don't nest |
| 21:17 | <@Vornicus-Latens> | It works better than /* */ because you can nest it |
| 21:17 | <@Vornicus-Latens> | But it's also worse because it looks horrible. |
| 21:17 | <@Derakon[work]> | Generally if I want to comment out blocks, I do so with //-style comments, to avoid that problem. |
| 21:18 | < ErikMesoy> | YO DAWG I HEAR YOU LIKE COMMENTS? |
| 21:18 | <@McMartin> | That tends to screw up my formatting |

| 21:21 | <@AnnoDomini> | This interpretation would be Dwarfhack or something. |
| 21:28 | <@Derakon[work]> | Just a quick sanity check: this is the right way to call free, right? |
| 21:28 | <@Derakon[work]> | if (foo != NULL) { |
| 21:28 | <@Derakon[work]> | free(foo); |
| 21:28 | <@Derakon[work]> | foo = NULL; |
| 21:28 | <@Derakon[work]> | } |
| 21:29 | <@AnnoDomini> | If the pointer doesn't point to nowhere, free the memory pointed by the pointer, and make the pointer point to nowhere. Sounds good to me. |

| 22:58 | <@ToxicFrog> | Derakon[work]: calling free() on NULL is in fact safe. |
| 22:58 | <@Derakon[work]> | Ah hah. |
| 23:01 | <@McMartin> | The Thing That Kills you is calling delete on something you allocated with new[], or vice versa. |
| 23:06 | <@Vornicus> | double frees are also bad but you'll get yelled at by at least the debug build if you do that. |
| 23:17 | < gnolam> | Don't count on that. |

| 23:30 | <@Vornicus> | Well, it may give you a stack trace. But figuring out why it's happening can be a real bitch. |
| 23:30 | <@Vornicus> | Since most of the time you're ending up freeing the same thing twice /in the same place/ |
| 23:31 | <@Vornicus> | So just removing the free gives you a memory leak. |
