| 00:09 | <@Derakon> | Hm. Recommendations for a free Windows program my sister can use to open the .tgz I sent her? |
| 00:09 | <@McMartin> | bsdtar is downloadable, I think. |
| 00:10 | <@McMartin> | Works without cygwin |
| 00:10 | <@McMartin> | WinRAR eats it but isn't truly free |
| 00:10 | <@Derakon> | Oh, bsdtar. I read "badtar" at first~ |
| 00:11 | <@Derakon> | Is WinRAR the one that shows its shareware screen for longer and longer as you refuse to pay for it, but never stops working? |
| 00:12 | <@Consul> | 7zip has been able to handle everything I've thrown at it. |
| 00:13 | <@ToxicFrog> | Derakon: no. |
| 00:13 | <@ToxicFrog> | It doesn't show it at all for the first month, and after that it shows it but can be dismissed immediately (and doesn't show it all if you use right-click commands like "create archive" or "unpack here"). |
| 00:14 | <@ToxicFrog> | 7zip can also tar.gz and tar.bz2 files, and is freeware. |
| 00:14 | <@Derakon> | Cool, thanks. |

| 06:29 | | * ToxicFrog stabs -0 in the face |
| 06:29 | <@ToxicFrog> | I can't figure out how to distinguish between -0 and +0. |
| 06:31 | <@SmithKurosaki> | Why do you need to |
| 06:31 | <@ToxicFrog> | Because otherwise my floating point writing code is lossy. |
| 06:32 | <@SmithKurosaki> | Ahh |
| 06:32 | <@ToxicFrog> | You tell it to store -0 and you get +0 out. |
| 06:32 | <@SmithKurosaki> | Pissing around with scheme again |
| 06:32 | <@ToxicFrog> | No, vstruct. |
| 06:32 | <@ToxicFrog> | sanooj reported some errors with floating point handling of subnormal numbers. |
| 06:32 | <@ToxicFrog> | I turned up this error while working to fix that one. |
| 06:33 | <@SmithKurosaki> | Argh |
| 06:35 | <@Derakon> | TF: can't just check the sign bit? |
| 06:36 | <@ToxicFrog> | Derakon: the code I'm working on is the code that turns a real number (of undefined internal representation) into a sequence of bits corresponding to an IEEE754 double. |
| 06:36 | <@ToxicFrog> | So, no. |
| 06:37 | <@ToxicFrog> | The reason I need to figure out whether 0 is -0 or +0 is so that I can write the correct sign bit. |
| 06:37 | <@SmithKurosaki> | ;.; |
| 06:37 | <@Derakon> | D'oh. |
| 06:39 | <@ToxicFrog> | Got it, thanks to #lua |
| 06:39 | <@ToxicFrog> | 1/-0 is -inf, and 1/0 is inf. |
| 06:39 | <@ToxicFrog> | And those are distinguishable. |

| 16:36 | <@ToxicFrog> | MyCatVerbs: it's an issue with the constant table optimize |
| 16:36 | <@ToxicFrog> | What happens is, it sees 0, and enters it into the constant table |
| 16:36 | <@ToxicFrog> | Then it sees -0, and checks to see if it's already in the table |
| 16:37 | <@ToxicFrog> | Which (since -0 == 0) it thinks it is, and it just creates a ref to the existing constant. |
| 16:37 | <@ToxicFrog> | You can work around it by making it nonconstant, eg: |
| 16:37 | <@ToxicFrog> | math.zero = 0 |
| 16:37 | <@ToxicFrog> | math.negzero = -math.zero |

| 18:37 | | * Derakon goes back to trying to figure out how to make classes in Cython. |
| 18:45 | <@Derakon> | Bah! http://paste.ubuntu.com/235336/ |
| 18:45 | <@Derakon> | Vector2D instances damn well *do* have an 'x' attribute! |
| 18:45 | <@Derakon> | So why can't you find them? |
| 18:49 | <@Derakon> | ...ah hah. Cython class fields are not public by default. |
| 18:52 | <@Derakon> | Okay! Running that test script using the Vector2D class that inherits from tuple: 4.86s. |
| 18:52 | <@Derakon> | Running it with the Cython class: 1.74s. |
| 18:52 | <@Derakon> | I...think it's time to switch to Cython for Vector2D. ?.? |
| 20:12 | <@Derakon> | Hey, Rhamphoryncus, do you know if there's a way to intercept the act of calling a function on a Python module, and route it to calling that same function on an instance of a class in that module? |
| 20:13 | <@Derakon> | I'm basically trying to implement singletons here without making the syntax hairy. |
| 20:13 | <@Derakon> | So I have a module that defines a class, and then an instance of that class, and you currently call functions by modulename.instanceofclass.functionName(). |
| 20:14 | <@Derakon> | And I'd like to make it just be modulename.functionName() without having to make a bunch of passthroughs for each function defined for the class. |
| 20:14 | <@Derakon> | Oh wait, Rhamphoryncus isn't here. |

| 20:18 | | * Derakon is getting to know this IRC client, and wishing it had more configuration related to the user list. |
| 20:19 | <@SmithKurosaki> | o.0 |
| 20:19 | <@SmithKurosaki> | What are you using Der? |

| 20:20 | <@AnnoDomini> | I think I tried Xchat once. Gave up almost immediately, when I learned it had not nipple-grade intuitiveness. |

| 20:21 | <@AnnoDomini> | The only truly intuitive interface is the nipple. Everything else is learned. |
| 20:21 | <@Derakon> | Dammit, doing /server in a new window shouldn't disconnect you from your existing windows! |
| 20:21 | <@AnnoDomini> | It's a quote, but I don't know whose. |
| 20:21 | <@SmithKurosaki> | Heh |
| 20:27 | <@ToxicFrog> | No. It shouldn't. And on mine, it doesn't. |
| 20:34 | <@Derakon> | Apparently this version distinguishes between "new windows" and "new server windows". |
| 20:34 | <@Derakon> | I have to do cmd-ctrl-N to get a new server window. |
| 20:36 | | ToxicFrog [~ToxicFrog@Admin.Nightstar.Net] has quit [Ping Timeout] |
| 20:43 | | * TheWatcher uses /connect to connect to different servers, or /server +<server2>, but suspects these are irssiisms |

| 20:46 | | mode/#code [+o ToxicFrog] by ChanServ |
| 21:29 | <@Vornicus-Latens> | the IRCD command to connect two /servers/ together is /connect. /server is the usual one for connecting a client to a server. |
| 21:30 | | * Derakon mutters at pyximport, which is supposed to automatically recompile Cython modules for me. |
| 21:30 | <@Derakon> | Problem is, as soon as I do "import pyximport", it tries to compile all of my modules immediately...of course, some of them depend on the vector2d module that hasn't gotten compiled by pyximport yet, so importing pyximport fails! |
| 21:31 | <@McMartin> | Vorn: Yes. /connect is an irssi-ism for "connect to this server without throwing out all existing ones" |
| 21:31 | <@Vornicus-Latens> | how nice. |
| 21:32 | | Vornicus-Latens is now known as Vornicus |
| 21:39 | <@Derakon> | What the Christ. |
| 21:40 | <@Derakon> | I can't compile the Cython version of the Vector2D class because before trying to compile, Cython is, for some godforsaken reason, trying to import everything *else* in the current directory! |
| 21:40 | <@Derakon> | Which of course depends on the Vector2D class that doesn't exist yet! |
| 21:40 | <@Vornicus> | uh...huh. |
| 21:40 | <@Derakon> | If I have just the vector2d.pyx file in a directory on its own, then it works. |
| 21:41 | <@Derakon> | As soon as I add files that depend on it, bam, failure. |
| 21:42 | <@Derakon> | Hrm...that's not strictly accurate. |
| 21:42 | | * Derakon digs in to find what file precisely is making it go bugfuck. |
| 21:44 | <@Derakon> | ...platform.py is making it go bugfuck. |
| 21:44 | <@Derakon> | platform.py is one of the simplest modules I *have*. |
| 21:46 | <@Derakon> | And it has an indirect dependency on vector2d via constants. |
| 21:53 | <@Derakon> | Okay, now I think it just doesn't like that I have a module named "platform" because it has a different module with the same name that it needs. |
| 21:53 | <@Derakon> | So, suggestions for a module name for a class that's just a container of information on platforms for the player to stand on? |
| 21:53 | <@Derakon> | (location and width, at the moment) |
| 21:53 | <@Vornicus> | "floor" |
| 21:53 | <@Derakon> | That sounds like it could also get me in trouble. |
| 21:54 | <@Derakon> | I thought of maybe "FloatingPlatform", but they don't necessarily float and that's kinda lengthy. |
| 22:05 | <@Myst> | PlayerPlatform ... isn't much shorter, though |
| 22:06 | <@Derakon> | And it's really just a chunk of land, so it's not unique to the player. |
| 22:06 | <@Myst> | ImmediateLand |
| 22:06 | <@Vornicus> | "ground" |
| 22:09 | <@AnnoDomini> | Hmmm. |
| 22:09 | <@AnnoDomini> | Scaffolding. |
| 22:10 | <@Derakon> | Scaffold works. |
| 22:16 | <@Derakon> | Hrm...so I'd like to make a subclass off of Vector2D that's exactly the same except its member values are ints instead of doubles, but I'm not allowed to redeclare self.x and self.y |
| 22:22 | <@AnnoDomini> | self.xx? :P |
| 22:29 | <@gnolam> | GGRTAGH |
| 22:29 | | * gnolam stab stab FUCKING STABS Fontforge. |
| 22:31 | <@AnnoDomini> | Have you considered multiclassing to Barbarian? |
| 22:31 | <@McMartin> | Not that kind of hacking, AD |
| 22:31 | <@AnnoDomini> | The powerful Rage class feature could increase your accuracy and damage by as much as 10%! |
| 22:33 | <@gnolam> | POS software like this convinces me that open source developers could possibly get paid for staying the hell away from user interfaces. |
| 22:36 | <@gnolam> | Then there's the whole issue of the underlying software itself claiming to be able to import SVGs... but failing miserably at the majority of them. |
| 22:36 | <@gnolam> | With no clues whatsoever to what triggers its gleeful mangling of vertex data. |
