| 00:04 | < Vornicus> | I think there's a closed form for trinomial distributions. |
| 00:05 | <@McMartin> | I bet it's really ugly though |
| 00:05 | < Vornicus> | No bet. |
| 00:12 | | * ToxicFrog eyes physics |
| 00:13 | <@ToxicFrog> | Ok, sanity check: 1 N is the force required to accelerate a 1kg mass at 1m/s^2; 1J is 1 Nm |
| 00:13 | <@ToxicFrog> | Yes? |
| 00:13 | < Vornicus> | Right |
| 00:13 | <@McMartin> | Yep |
| 00:13 | <@ToxicFrog> | Ok, so |
| 00:13 | <@ToxicFrog> | We take a 1kg mass |
| 00:13 | <@ToxicFrog> | We apply 1N to it for 1s |
| 00:13 | < Vornicus> | okay. |
| 00:13 | < Vornicus> | it moves half a meter. |
| 00:14 | <@ToxicFrog> | It now has a velocity of 1 m/s, and has moved half a meter. |
| 00:14 | < Vornicus> | Yep. |
| 00:14 | <@McMartin> | No problems so far. |
| 00:14 | <@ToxicFrog> | So we've put 1/2 J into it. |
| 00:14 | < Vornicus> | Yep. |
| 00:14 | <@ToxicFrog> | But it has 1J of kinetic energy |
| 00:14 | < Vornicus> | Nope. |
| 00:15 | < Vornicus> | mv^2 / 2 |
| 00:17 | <@ToxicFrog> | Hmm. |
| 00:17 | < Vornicus> | (trust us on that one, it just plain don't work otherwise) |
| 00:18 | <@McMartin> | (It falls out of an integration) |
| 00:19 | <@ToxicFrog> | (Oh. That explains it.) |
| 00:20 | <@ToxicFrog> | I was thinking on this while cooking, and I must have misplaced something while working backwards from relativistic KE. |
| 00:20 | <@McMartin> | (KE is the integration of force * dx.) |
| 01:14 | <@MyCatVerbs> | McMartin: integral with respect to what, displacement? |
| 01:15 | <@McMartin> | Yes, that's the "dx". x is displacement. |
| 01:15 | <@MyCatVerbs> | D'ahhh. Nice. |
| 01:16 | <@McMartin> | Making physics equations fall out of the descriptions of the measured quantities: One of the only things calculus is directly applicable to |
| 01:16 | <@MyCatVerbs> | That and physical simulation, no? |
| 01:17 | <@McMartin> | No, you do that with the physics equations you got in the previous step |
| 01:18 | <@MyCatVerbs> | Ah. k. |

| 19:26 | | * ToxicFrog resumes his regular schedule of kicking Ubuntu in the balls over and over again |
| 19:38 | <@ToxicFrog> | The "select best mirror" tool will happily give me a mirror that doesn't actually support this architecture. |
| 19:38 | <@ToxicFrog> | And the only way to find out if a mirror works is to exit the mirror selection tool. |
| 19:38 | <@ToxicFrog> | (at which point it will go "you need to update your repo metadata...oh hey, the mirror you chose doesn't work. Goodbye!") |
| 21:54 | <@ToxicFrog> | /* Prevent time-travel paradoxes */ |
| 21:54 | | * jerith does so. |
| 21:55 | < Shoukanjuu> | In doing so, you may have just caused one >.> |
| 21:56 | | * jerith preemptively shoots Shoukanjuu. |
| 21:57 | < Shoukanjuu> | Good thing I'm of the paranoid type. *shows his kevlar jacket* Never know when I'm gonna get shot |
| 21:57 | <@ToxicFrog> | That's a comment from the CPL (Content Policy Language) evaluator. |

| 21:58 | <@ToxicFrog> | Hello. |
| 21:58 | < Greenlantern> | huh |
| 21:58 | < Greenlantern> | hi frog |
| 21:58 | < Shoukanjuu> | Hey, grennlantern :P |
| 21:59 | < Greenlantern> | wassup everybody |
| 21:59 | < Shoukanjuu> | Soul of the Fire. *nods* |
| 22:00 | < Greenlantern> | sounds good |
| 22:00 | < Greenlantern> | u have a soul |
| 22:05 | <@ToxicFrog> | Jury's still out on that~ |
| 22:06 | < Greenlantern> | lol |
| 22:06 | < Greenlantern> | i bribed da jury |
| 22:16 | < Shoukanjuu> | Nah |
| 22:17 | < Shoukanjuu> | North Americans don't have souls :O |
| 22:17 | < Greenlantern> | coz thee attacked iraq? |
| 22:17 | <@McMartin> | If that's all it took, humanity has been soulless for millions of years. |
| 22:18 | < Shoukanjuu> | Nah, federal outlaw. |
| 22:18 | < Greenlantern> | americans r humans regardless of woteva |
| 22:22 | | * AnnoDomini is unsure he likes single character substitutions for real words... wait, what am I saying? I am sure. |
| 22:23 | < Shoukanjuu> | >_> |
| 22:23 | < Shoukanjuu> | k |
| 22:23 | < Shoukanjuu> | <__< |
| 22:25 | | * ToxicFrog throws both Greenlantern and Shoukanjuu to the snakes |
| 22:27 | <@gnolam> | Just like writing the pronoun "I" with a lowercase 'i'. That should be a capital offense. |
| 22:27 | <@gnolam> | *ba-dum-dish!* |
| 22:27 | < Greenlantern> | capital defense |
| 22:28 | | * Shoukanjuu goes into a berserker rage and kills everything in the room with his bare hands before collapsing in a dark corner and tremlbing uncontrollably |
| 22:28 | < Greenlantern> | wot caused this sudden break of aggression shoukan |
| 22:29 | < Shoukanjuu> | I hate snaked x_X |
| 22:29 | <@AnnoDomini> | Shoukanjuu is a ninja. Ninjas fight ALL the time. The purpose of the ninja is to flip out and kill everybody. |
| 22:29 | < Shoukanjuu> | snakes* |
| 22:29 | <@gnolam> | Gah. ECL doesn't seem to have any Windows binaries anymore. Suggestions for other Common Lisp implementations on Windows? |
| 22:30 | <@gnolam> | And anything that requires Cygwin and/or Emacs is out. |
| 22:30 | <@McMartin> | Does Allegro CL still have a free Windows Demo? |
| 22:32 | <@gnolam> | It does. But it expires every 30 days and is sort of... crap. |
| 22:34 | <@McMartin> | Then WinEmacs is probably still your best bet. =P |
| 22:35 | <@McMartin> | Or use OCaml instead of CL, but that's presumably not an option here~ |
| 22:43 | < Greenlantern> | hm |
| 22:43 | < Greenlantern> | winlinux is da best |
| 22:46 | <@ToxicFrog> | gnolam: why is Cygwin out? |
| 22:47 | < Greenlantern> | nobody knows |
| 22:48 | <@ToxicFrog> | gnolam: actually, better idea - build it under mingw? |
| 22:48 | < Greenlantern> | yes |
| 22:57 | <@gnolam> | Call it a severe allergy. |
| 22:59 | <@gnolam> | And I won't even try building it with MinGW. I've had way too low a success rate to even consider it. |
| 22:59 | <@gnolam> | People's Windows builds usually require one of two things - Cygwin and a metric assload of dependency hell or some arcane version of MSVC. |
| 23:01 | <@gnolam> | :P |
| 23:02 | <@gnolam> | And I forgot: (for both alternatives) + some positively eldritch non-standard build tool. |
| 23:02 | <@McMartin> | If you just want a personal copy, MSVC Express is reasonably robust, and doesn't cost money. |
| 23:10 | <@ToxicFrog> | i386 is little-endian, stack grows downwards, right? |
| 23:44 | <@McMartin> | i386 is little-endian, and I believe the stack grows downwards. |
| 23:44 | <@McMartin> | SP+IX is the usual form of computed offset. |
