| 02:41 | | * Janus comes to know trivial success! http://dl.dropbox.com/u/3108480/vectorfieldminorprogressIguess.png |
| 02:42 | < Janus> | Now I just need to figure out a way to let the wind drain out of the sides. It kinda does a weird... ripple into the edge, then ripples right back. Like it's in a box |
| 02:42 | <@Alek> | whoa. |
| 02:42 | <@Alek> | a png isn't supposed to be animated. |
| 02:43 | <~Vornicus> | Holy shit, Janus |
| 02:43 | <&McMartin> | What are you viewing it with? I get no animation here. |
| 02:43 | < Janus> | Howdy! |
| 02:44 | < Janus> | It shouldn't be animated. If it is, I'd like to see it |
| 02:44 | < Namegduf> | It's causing an optical illusion for me. |
| 02:44 | < Namegduf> | If I state at the centre, it starts rippling. |
| 02:45 | <@Alek> | yup, optical illusion. |
| 02:46 | <@Alek> | and a 3d-ish effect if you unfocus. |
| 02:47 | <~Vornicus> | Janus: is the magnitude of the vectors being considered there? |
| 02:48 | | * Janus takes off glasses. Oh hey it looks like a ... well, 3D thing! |
| 02:49 | < Janus> | I thought it was. I might be wrong though. The four sides all have their own vector, which doesn't change. It let's me bleed in wind from one side, but that might not be a good way to do it I'm guessing. |
| 02:51 | < Janus> | Every pass, a vector has it's four neighbors (or three and the one side if it's on the edge, or two neighbors, two edges if it's a corner) added onto it, and then it's divided by the combined magnitude. |
| 02:52 | < Janus> | And that's... all it is. Definitely isn't how wind works but it seems convincing somehow |
| 02:55 | < Janus> | *whoops, not the combined magnitude. Just... just the number 5. Pfft! |
| 02:58 | | Kindamoody is now known as Kindamoody|afk |
| 03:19 | < Janus> | Okay, this time it actually does move! http://dl.dropbox.com/u/3108480/greenwindything.gif |
| 03:20 | <&McMartin> | That is pretty cool |
| 03:21 | < Janus> | Thanks! Now I just need to convince it that there's no box around it |
| 03:22 | <&McMartin> | I'm wondering if you're actually modelling not wind but a spring |
| 03:24 | | Vash [Vash@Nightstar-cdeba41f.wlfrct.sbcglobal.net] has quit [Connection closed] |
| 03:29 | < Janus> | I might be! The only rule they abide by, is taking a group of 5 vectors, and averaging them together over time. The only difference between the wall, and a vector in the middle, is that the wall's doesn't change from 0, 0. ... maybe that's it. ... that IS it. |
| 03:35 | <~Vornicus> | Yeah, that would do it - if you're reading from the wall then it's a "still air" input |

| 04:08 | | * Derakon eyes the scipy dudes, wonders why there's no 64-bit scipy for OSX that doesn't use the built-in Python. |
| 04:15 | | * Janus read "spicy dudes". Never quite recovered |
| 04:16 | | * Vornicus pokes vaguely at MS Access. Want to build a form that lets him select things by name instead of ID. |
| 04:19 | | * Derakon tries to figure out the proper way in Python to generate the sequence (0, 0), (0, 1), (0, 2), ..., (1, 0), (1, 1), (1, 2), ... |
| 04:19 | <&Derakon> | I mean, I could use a doubly-nested loop, but bah. |
| 04:21 | <@ToxicFrog> | [(x,y) for x in range(0,3) for y in range(0,3)] ? |
| 04:21 | <&Derakon> | Basically the same as nested loops, except you can't use xrange. |
| 04:22 | <@ToxicFrog> | Ok, in that case I don't understand what your underlying objection is |
| 04:22 | <&Derakon> | I want a one-liner generator function to spit out the sequence. |
| 04:22 | <~Vornicus> | TF gave you one. |
| 04:23 | <&Derakon> | It's not a generator -- it'd make all the points first and then iterate through them. |
| 04:23 | <~Vornicus> | OKay fine, ((x,y) for x in range(3) for y in range(3)) |
| 04:23 | <&Derakon> | That's purely a stylistic problem for the scale I'm operating on at the moment, mind you. |
| 04:24 | <&Derakon> | Hunh, okay. |
| 04:24 | <&Derakon> | Thanks. |
| 04:24 | <~Vornicus> | You can multiloop in genexps and other comprehensions like that. |
| 04:44 | <&McMartin> | Holy shit when did Python add generator comprehensions |
| 04:44 | | * McMartin actually is the :black101: emoticon right now |
| 04:46 | <~Vornicus> | A teeth-gritting ax-waver? |
| 04:46 | <&McMartin> | Yes. |
| 04:46 | <~Vornicus> | McM: um |
| 04:47 | <~Vornicus> | 2.1 I think? |
| 04:47 | <&McMartin> | Man, I've been missing out |
| 04:47 | <&McMartin> | That is zorking jenth. |
| 04:47 | | * McMartin is a fan of lazy evaluation and list comprehension abuse! |
| 04:47 | <~Vornicus> | Yeah, use () instead of [] and you get an iterator instead of a list |
| 04:48 | <&Derakon> | Okay, that's about 45 minutes from start to implementing a simple program that shows 100 varicolored squares flying around a black field. |
| 04:48 | <~Vornicus> | in 2.7 and py3 use {} instead and you get a set or dict |
| 04:48 | <&McMartin> | Yeah, I knew dict comprehensions were new |
| 04:48 | <&McMartin> | (and also zorking jenth) |
| 04:48 | <~Vornicus> | and python.org is down so I can't actually check version history |
| 04:48 | <&Derakon> | Now to try to make them repel each other. |
| 04:49 | <~Vornicus> | it was 2.1 or 2.2 though, and I've been using them forever |
| 04:49 | <&McMartin> | This means you should be able to do the horrifying Haskell tricks where you define a recurrence in terms of two infinite lists that refer to one another |
| 04:49 | | * Derakon tries to think of the best way to write "sum of vectors from this point to all other points in this array". |
| 04:50 | <~Vornicus> | McM: though I don't think you can index into a standard genexp. |
| 04:50 | <&McMartin> | they're easy to force though |
| 04:51 | <&McMartin> | [x for x in genexp] |
| 04:51 | <&McMartin> | Do not attempt on infinite generators |
| 04:51 | <&Derakon> | Heh. |
| 04:51 | <~Vornicus> | Der: {a: sum(b - a for b in points) for a in points} |
| 04:51 | <&McMartin> | Professional software developer, closed form, lazy evaluation |
| 04:52 | <~Vornicus> | GIves you a dictionary of points to summed distances. |
| 04:52 | <&McMartin> | Oh wait |
| 04:52 | <&Derakon> | That works, Vorn. |
| 04:52 | <&McMartin> | The genexps won't have automemoization. |
| 04:53 | <~Vornicus> | No they won't. |
| 04:53 | <&McMartin> | That means that you won't get the dynamic programming answer, but the exptime one. |
| 04:53 | <&Derakon> | Though I'm in 2.6 so I can't actually use a comprehension like that. |
| 04:53 | <&McMartin> | Boo. |
| 04:53 | <~Vornicus> | dict((a, sum(b - a for b in points)) for a in points) |
| 04:53 | <&Derakon> | Heh. |
| 04:54 | <~Vornicus> | No problem~ |
| 04:55 | <&Derakon> | Actually what I want is numpy.sum(b - a, axis = 0) for b in points, I think. |
| 04:55 | <~Vornicus> | I should really figure out what I'm doing with numpy |
| 04:56 | <&Derakon> | It's handy. |
| 04:56 | <~Vornicus> | I suspect so! |
| 04:56 | <~Vornicus> | I've been building my numerical tools by hand, but I almost have the chops to do that. |
| 04:58 | <&Derakon> | ...right, this function appears to actually be "everything gets attracted/repelled from the y = x line". Whups~ |
| 04:58 | <&Derakon> | Also, to work properly I need to handle the fact that the universe is toroidal. |
| 04:58 | <~Vornicus> | Whups |
| 05:00 | <&Derakon> | And wow is there a big difference when I do a nested loop over all points in Python. |
| 05:00 | <&Derakon> | Goes from perfectly smooth to chugging along. |

| 17:02 | < Tarinaky> | People complaining about my code style/method names instead of actually writing some god damn code. |
| 17:03 | < Tarinaky> | And I mean fully unironically complaining about me instinctively defaulting to foo_bar() style method names instead of the more Java-ish fooBar() |
| 17:03 | < Tarinaky> | Also complaining that I abbreviated link to lnk in the names for a family of methods. |
