| 11:20 | | * gnolam stabs OpenGL implementations with a rusty shiv. |
| 11:23 | < gnolam> | It looks like I'm going to have to do a complete feature freeze to instead start adding fifty gazillion #ifdef #else statements because it's apparently too goddamned hard to name the exposed functions after the goddamned standard. |
| 11:28 | | * TheWatcher would vaguely suggest writing wrapper functions to try to centralise contact with opengl and abstract it away from the rest of your code, if possible |
| 11:30 | < gnolam> | Yeah. It's called GLEW. |
| 11:31 | < gnolam> | Which the system this has to work on, but I can't develop on, /doesn't have/. |

| 13:16 | <@TheWatcher> | ... |
| 13:18 | <@TheWatcher> | Obviously someone doesn't know how that works :/ |
| 14:08 | < MyCatVerbs> | TheWatcher: you have indeed, in a single sentence, identified exactly the root cause of the issue. |
| 14:09 | < MyCatVerbs> | In his defence, the man who committed the atrocity is a) my boss, b) not really a programmer but does have enough common sense to c) hire programmers and d) usually listens to us, thankfully. |

| 14:13 | < SmithKurosaki> | o.0 |
| 14:14 | < SmithKurosaki> | How does that work |
| 14:14 | < MyCatVerbs> | SmithKurosaki: order by RAND()? |
| 14:15 | < SmithKurosaki> | Yea |
| 14:15 | < MyCatVerbs> | It scans every row in the table, assigns a random integer to every each, sorts the rows by the integer that it just generated, and returns rows from the top down. |
| 14:15 | < SmithKurosaki> | That sounds not all that good |
| 14:15 | < MyCatVerbs> | Notably, the answer to "when do I want to perform a full-table sort?" is usually "never, my friend". |
| 14:16 | < SmithKurosaki> | (You sort as you insert...) |
| 14:17 | < MyCatVerbs> | Well, kinda. Indexes are b-trees. You put an index on the column-tuple that you're planning to sort on, and then traversing the database in-order of that column is quite cheap. |
| 14:17 | < MyCatVerbs> | Fortunately there's already an index on the only column that actually needs it in that table. ^^ |
| 14:17 | < SmithKurosaki> | (Head not all here, words are confusing me) |
| 14:18 | < MyCatVerbs> | SmithKurosaki: The column that you plan to query from in sorted order... |
| 14:18 | < MyCatVerbs> | You put an index on that column. |
| 14:18 | < SmithKurosaki> | OK |
| 14:18 | < MyCatVerbs> | Indexes in SQL databases are a data structure called a "b-tree". |
| 14:18 | < SmithKurosaki> | Ahh, it |
| 14:18 | < SmithKurosaki> | 's SQL... |
| 14:19 | < MyCatVerbs> | B-trees have two neat properties: they let you find things in them in almost-constant time... |
| 14:19 | < SmithKurosaki> | I have used databases exactly once |
| 14:19 | < SmithKurosaki> | Nice |
| 14:19 | < MyCatVerbs> | ...and they let you enumerate the elements in them very, very cheaply. |
| 14:19 | < MyCatVerbs> | In order, I mean. |
| 14:19 | < MyCatVerbs> | Enumerating a b-tree's data in-order is quite cheap, though if you're unlucky with the table layout then the rows might be really fragmented. But what the Hell. |

| 20:59 | < McMartin> | THANK GOD IT'S YOU |
| 20:59 | | * McMartin explodes |
| 20:59 | | * Derakon[work] gets the mop. |
| 20:59 | < McMartin> | (Wait, were they the ones who exploded or were they the ones you were trying to rescue?) |
| 21:00 | < Derakon[work]> | Error: missing required context. Please reboot universe and restart. |
| 21:00 | < McMartin> | In other news, I've just made yet another emergency patch and am likely to spend the time spent validating the patch arguing for why it should be reverted. |
| 21:22 | < McMartin> | Hooray, my coworker got a new Android phone. As a side effect, her ringtone's background music no longer sounds like SHODAN spinning up. |
| 21:48 | < Derakon[work]> | So first I tried to build OMX (the microscope program). It complained about not having wxWidgets. So I downloaded and built wxWidgets. Then OMX complained about not having OpenGL access in wx. So I enabled OpenGL in wxWidgets and rebuilt it (why it wasn't enabled from the start, I have no idea). Then it complained about not having python24_d.lib, the debug build of Python 2.4. So I downloaded Python 2.4 and built it. Then OMX built. I tri |
| 21:48 | < Derakon[work]> | ed to run it. Python threw an exception because it tried to use an invalid signal. So I applied a patch to make it only use valid signals and rebuilt it, then tried to run OMX again. It complained that it couldn't find perfectly valid Python modules. |
| 21:48 | < Derakon[work]> | That's where I am right now. |
| 21:48 | < Derakon[work]> | And I'm sick of dealing with build crap. I hate all dependencies forever. >.< |
| 21:56 | < McMartin> | wxWidgets >.< |
| 21:57 | < McMartin> | wxWidgets isn't a Widget library, it's a test suite for compiler error generators |
| 21:57 | < Derakon[work]> | I think the problem ATM is probably in the Python build, but it's hard to tell! |
| 21:57 | < McMartin> | I have literally not been able to compile so much as Hello World copy-pasted from their own docs on wx. |
| 21:57 | < Derakon[work]> | Heh. |
| 21:57 | < Derakon[work]> | I would love to replace it. Unfortunately not feasible. It has its hooks throughout the program. |
| 21:58 | < McMartin> | I've seen shipped binaries -- which only worked on Windows, the linux binaries just segfaulted immediately -- so it has to work under *some* conditions |
| 21:58 | < McMartin> | But God if I know how to set said conditions up. |
| 22:05 | < Vornotron> | "thank god it's you!" is the exploding ones. |
| 22:06 | < Vornotron> | also "kill me!", "frog blast the vent core!", and several others |

| 22:13 | < McMartin> | Yeah, I knew Frog Blast &c was one. |
| 22:26 | < Vornicus> | actually TGIY is the one from M1, where the good guys said "they're everywhere!" |
