| 00:01 | < RichyB> | The creation dates should be in something like iso-8601 so an asciibetical sort will work |
| 00:01 | <&Derakon> | Well, as the output of ls -l they're in like "Mar 5 2009". |
| 00:01 | < RichyB> | assuming that your ls prints the same fields as mine, ls -l | sort -k 6 |
| 00:02 | < RichyB> | Derakon, ls -l --time-style=full-iso # on GNU |
| 00:02 | <&Derakon> | Ahh, danke |
| 00:03 | < RichyB> | better yet |
| 00:03 | < RichyB> | ls -l -c # sorts by ctime |
| 00:03 | < RichyB> | -m for mtime and -a for atime |
| 00:03 | < RichyB> | oops |
| 00:03 | <&Derakon> | I was trying to use that, but feeding the output of find through it wasn't working so well. |
| 00:04 | < RichyB> | oh gack |
| 00:04 | < RichyB> | sorry, I have those options wrong and frankly the man page for GNU ls doesn't make sense to me |
| 00:04 | <&Derakon> | Heh. S'alright, the time-style argument worked. |
| 00:05 | < RichyB> | -c for ctime, -t for mtime, and there is no atime support (and you shouldn't have atime switched on in your filesystems anyway because it sucks) |
| 00:11 | <&Derakon> | Right, time to go. Thanks, Rich. |

| 00:16 | < gnolam> | RichyB: Sans serif fonts strike again. I read that as "the man page for GNU is doesn't make sense to me". In Borat's voice. |
| 00:16 | < RichyB> | Have you tried monofur? |
| 00:16 | < RichyB> | It's a monospace font designed by/for Perl programmers. |
| 00:17 | < RichyB> | $5SZ are all wildly distinct in it, as a iIlLjJ|/\ |
| 00:17 | < RichyB> | looks a bit weird as a result but it's vaguely arty. |

| 03:45 | <&McMartin> | Hmm |
| 03:45 | | * McMartin has a decent idea for how to do better piece animations in Hex Inverter. |
| 03:46 | <&McMartin> | When the game-referee object queues up the pieces that must flip, instead of building a single worklist and animating one flip at a time, it queues them all simultaneously and has the animating objects each start on a fuse |
| 03:46 | <&McMartin> | By extending the fuse for later pieces of the sequence, I should be able to get an overlapping wave effect at any speed I want |
| 03:46 | <&McMartin> | And by having the animation-complete event decrement a counter, I can also then have the referee object be able to tell when animation is done and it's therefore time to transfer control to the next player. |

| 13:10 | | * Rhamphoryncus ponders methods of correcting lateness |
| 13:11 | <@Tamber> | Time travel. |
| 13:11 | < Rhamphoryncus> | I'm thinking I need two: one for bulk changes to the route (20 new vehicles added, all at the start). That can be a simple cap on how late an individual station will be. |
| 13:11 | < Rhamphoryncus> | I'd get yelled at for that. |
| 13:12 | < Rhamphoryncus> | The other needs to handle small yet frequent lateness. Perhaps a counter, add 20 each time a vehicle is late, divide by 2 each time they're not. If it hits 100 I skip a departure window. |
| 13:28 | < Rhamphoryncus> | For that matter I could just add/subtract constant amounts |
| 13:30 | | * TheWatcher eyes |
| 13:30 | < Rhamphoryncus> | Commentary welcome. It has the feeling of a giant bodge (and was when I did it a couple years ago.) |
| 13:30 | <@TheWatcher> | Well, that explains why I was having problems getting firefox to parse this xml, even though it is valid |
| 13:31 | <@TheWatcher> | apparently firefox /never loads external dtds/ |
| 13:31 | < Rhamphoryncus> | lol |
| 13:31 | <@TheWatcher> | So, now I probably need to inline the fucker in every response |
| 13:31 | < Rhamphoryncus> | ouch |
| 13:35 | <@TheWatcher> | It's easy enough, just that I shouldn't bloody need to do it |
| 13:39 | <@jerith> | TheWatcher: Isn't an external DTD an attack vector? |
| 13:42 | < Rhamphoryncus> | It's a pity there's no same-host rule for allowing DTDs |
| 13:46 | <@TheWatcher> | jerith: in this case? No idea how it could be used as one any more than the xml itself - the page contains some javascript that asks the server for a list of statements, the server responds with '<?xml version="1.0" encoding="UTF-8" standalone="no" ?>\n<!DOCTYPE response SYSTEM "dtds/cstateapi.dtd">\n<response>....</response>' which is then parsed by the browser into an XML DOM from which I pull the statement info |
| 13:47 | <@jerith> | Where does it look for external DTDs? |
| 13:47 | | * jerith is rather rusty on his XML. |
| 13:48 | <@TheWatcher> | "dtd/cstateapi.dtd" - that's the URL of the dtd, relative url (which is valid, I checked) |

| 20:59 | <&Derakon> | Whelp, I got basic shader false-color working now. Primarily because some nice fellow on the pyopengl-users@ list handed me an example to crib from. |
| 20:59 | | Attilla [Obsolete@Nightstar-514682b9.as43234.net] has quit [Ping timeout: 121 seconds] |
| 21:00 | <&Derakon> | Now I'm working on integrating this into my main program. |
| 21:01 | <&Derakon> | Which program includes the ability to set the blackpoint and whitepoint of the image (i.e. the values below/above which any pixel is rendered as black/white, setting grayscale as well to suit). |
| 21:01 | <&Derakon> | Currently this is being done by calls to glPixelTransfer to set RGB scale and biases, but I suspect I can replicate it using the fragment shader... |
| 21:02 | <&Derakon> | I just need to pass in an offset and multiplier. However, I'm really not clear on how values are passed to shaders. |
| 21:04 | <&Derakon> | Seems to involve the glUniform call somehow... |
| 21:04 | <&Derakon> | My code: http://pastebin.com/sfMFZ18g |
| 21:09 | <&Derakon> | ...hm, okay, I think that works. |
| 21:09 | <&Derakon> | I still have no idea how the textures are getting passed to the shader, but I was able to pass a vec2 in with any values I cared to specify. |
| 21:15 | | Attilla [Obsolete@Nightstar-514682b9.as43234.net] has joined #code |
| 21:19 | <&Derakon> | Hm, but capping the value to the range (0, 1) isn't working on the top end. That is, I have a uniform gradient from 0 to 1 |
| 21:19 | <&Derakon> | If I subtract off .5 from each value, then half the image is black, as expected. |
| 21:20 | | Attilla [Obsolete@Nightstar-514682b9.as43234.net] has quit [Ping timeout: 121 seconds] |
| 21:20 | <&Derakon> | If I add .5 instead, then 1 is reached sooner, but instead of half of the image being white, it shows the other half as black. |
| 21:20 | <&Derakon> | I'm using this: min(1, max(0, (color.a + scaling.x) * scaling.y)) |
| 21:20 | <&Derakon> | As the lookup value into a texture1D call. |
| 21:21 | <&Derakon> | To be more explicit, say my image is [0,1,2,3,4,5,6,7,8,9] |
| 21:22 | <&Derakon> | In the first case, I subtract half the range, I get [0,0,0,0,0,1,2,3,4,5] |
| 21:22 | <&McMartin> | That's the kind of image an idiot would put on his luggage! |
| 21:22 | <&McMartin> | >_> |
| 21:22 | <&Derakon> | In the second case, I add half the range, I get [5,6,7,8,9,0,0,0,0,0] |
| 21:22 | | * Derakon facepalms. |
| 21:26 | <&Derakon> | Ahh, fixed by changing the "min(1, ..." to "min(.9999, ..." |
| 21:27 | <&McMartin> | Floating Point Instability'd? |
| 21:30 | <&Derakon> | I guess. |
