| 05:21 | <@Derakon> | 1036-node triangulation done in 9.103s (last night was 10.43s). |
| 05:21 | <@Derakon> | The improvement came from tracking down how I was getting those weird edges: redundant entries in the edge queue. |
| 05:54 | <@Derakon> | Oh, interesting. |
| 05:55 | <@Derakon> | Apparently most of my runtime is spent in preparing the edge queue. |
| 05:55 | <@Derakon> | ... |
| 05:55 | <@Derakon> | Yeah, there we go. |
| 05:58 | | * Derakon cuts his runtime by a factor of 8. |
| 05:59 | < Vornicus> | Preparing the edge queue. Was killing your runtime. |
| 05:59 | < Vornicus> | wtf? |
| 05:59 | <@Derakon> | Yeah. |
| 05:59 | <@Derakon> | I was doing a check to make certain I didn't add redundant edges to the queue. |
| 06:00 | <@Derakon> | That meant n^2 edge-edge comparisons. |
| 06:00 | <@Derakon> | Just replace that with a hash lookup and now it's n*log(n)! |
| 06:00 | <@Derakon> | (Er, that's not a factorial...) |
| 06:01 | | * Derakon triangulates 4015 nodes in 5.407s. |
| 06:01 | <@Derakon> | I think that's adequate for my purposes. |

| 06:15 | <@Derakon> | And a further .4s off of that test as well, on realizing that I don't actually need the queue to be ordered, and thus edgeQueue and queueSet are redundant. :) |
| 06:21 | <@Derakon> | Hm, my circumcircle code is buggy, causing me to choose an incorrect starting hull: http://derakon.dyndns.org/~chriswei/temp2/badhull.png |
| 06:21 | <@Derakon> | I don't care what pair of those three nodes you start with, the third node is not the one that makes the smallest inscribed circumcircle. |
| 06:24 | < Vornicus> | Yeah no. |

| 06:47 | < Vornicus> | Mmm, problem with that pair is that it picked top and bottom first. |
| 06:48 | < Vornicus> | Then, trying to find a "smallest" it failed miserably because they all have that point within them. |

| 20:55 | | * gnolam stabs the GIMP with something nasty and painful. |

| 21:07 | < gnolam> | "Yo dawg, I put some poison in your poison so you can die while you die"? |
| 21:07 | < celticminstrel> | Why do you stab the GIMP? |
| 21:09 | < simon_> | I'd stab it. |
| 21:10 | < simon_> | I even got an alias gimp=pinta in my .bashrc |
| 21:31 | < gnolam> | celticminstrel: because it's awful. |
| 21:32 | < gnolam> | For example, it keeps trying to create windows larger than my desktop. |
| 21:32 | < Abu[Laptop]> | Paint is more user-friendly. |
| 21:40 | | Stalker [Z@26ECB6.A4B64C.298B52.D80DA0] has quit [Ping timeout: 121 seconds] |
| 21:43 | < gnolam> | More? The user interface is a nightmare of window hunting (its window management is just awful in general), its icon set is confusing and unintuitive (I know exactly what tools are available, and I /still/ have problems finding the tool I'm after), important tools are missing *cough*lines*cough*, existing tools are poorly designed (perspective correction, I'm looking at you), etc etc |
| 21:45 | <@TheWatcher> | While I agree that GIMP lacks important primative tools, you do know about shift and lines, yes? |
| 21:46 | < gnolam> | Not the same thing. |
| 21:46 | <@TheWatcher> | Howso? |
| 21:47 | < gnolam> | Antialiasing/transparency. |
| 21:48 | < gnolam> | Also: JESUS H CHRIST IT'S SLOW |
| 21:48 | <@TheWatcher> | If you want antialiased lines, use the brush tool+shift, if you don't use the pencil tool+shift? |
| 21:48 | <@TheWatcher> | Well, why not just use photoshop rather than complaining about it? |
| 21:49 | <@TheWatcher> | (which addresses some - but, I note, not all - of GIMP's deficiencies, and adds regular random crashes!) |
| 21:50 | < Abu[Laptop]> | WINE things up and load up MS Paint. |
| 21:51 | < gnolam> | Transparency stacks. |
| 21:51 | < gnolam> | Which means that you get ugly blots at the end of lines. |
| 21:51 | < gnolam> | Which is why you should have a goddamned line tool to begin with. |
| 21:52 | < gnolam> | (That, and its mode of interaction is better in many cases. Shift lines should still be in there, but a lot of the times, the standard-for-everyone-except-the-GIMP line tool is better suited.) |
| 21:53 | < gnolam> | And I can't be arsed to pirate Photoshop. :P |

| 22:09 | | * Derakon eyes the wx-users mailing list. |
| 22:10 | <@Derakon> | Apparently I've been trying to get WX's ScrolledWindow class to do something it's not meant to do. |
| 22:10 | <@Derakon> | It is intended for use as a scrollable canvas, not as a container for generic UI widgets. |
| 22:10 | | * Derakon mutters. |
| 22:14 | < celticminstrel> | Well, that's not terribly useful, is it? |
| 22:15 | < celticminstrel> | (Though it'll be sufficient for me when I get there.) |
| 22:15 | <@Derakon> | The ironic thing here is that I actually want to use them to limit the size of displayed images...but those images are themselves interactive UI widgets and I'm not about to try to rewrite their code to work in a different context. |
