| 03:27 | < BlueTiger> | Hey, could anyone help me with a Ruby on Rails problem? |
| 03:28 | <@Vornicus> | I haven't much touched config. |
| 03:29 | < BlueTiger> | well, I'm not sure if it has to do with my config or not |
| 03:29 | < BlueTiger> | Every time I try to set up the scaffold it tells me "Before updating scaffolding from a new DB schema, try creating a table for your model" |
| 03:30 | < BlueTiger> | I've verified all the table names and that they are there, etc. |
| 03:30 | <@Vornicus> | What is the table name? |
| 03:30 | < BlueTiger> | sandbox |
| 03:30 | <@Vornicus> | ah |
| 03:31 | <@Vornicus> | Unless you specifically tell it that you want to use a table named "sandbox", the Sandbox model will assume you want a table called sandboxes |
| 03:31 | < BlueTiger> | ok |
| 03:32 | <@ToxicFrog> | ...what if you have a class for which the plural is not ..s? |
| 03:32 | <@Vornicus> | It knows a large number of exceptions. |
| 03:32 | < BlueTiger> | aaand that did it. THanks |
| 03:33 | <@Vornicus> | Also, you can specifically name the table differently. |
| 03:34 | <@Vornicus> | and the pluralization. Let me see if I can find its list of exceptions |

| 06:56 | < Reiver> | For XP. |
| 06:57 | < Reiver> | AKA when going through folders and things, when you right-click you get a context menu of your various options. |
| 06:57 | < Reiver> | I have 'helpful' additions from no less than three media players on this menu. ¬¬ |
| 07:10 | <@Vornicus> | Ah |
| 07:11 | <@Vornicus> | Yeah, there's a way to fiddle with that |
| 07:11 | <@Vornicus> | Last time I tried was Win2k though, so this may be wrong: Settings -> Folder Options -> File Types |
| 07:12 | <@Vornicus> | And somewhere in there should be a way of seeing and editing the options that show up when you right click a file of a particular type. |
| 07:14 | < Reiver> | Oooh |
| 07:14 | | * Reiver investigates. |
| 07:18 | < Reiver> | Works! |
| 07:18 | < Reiver> | Thanks. |
| 07:19 | <@Vornicus> | That's among the more powerful sections of shell that you can get to in there. |
| 07:19 | | * Reiver nods. |
| 07:19 | <@Vornicus> | YOu can create new custom commands to open programs with particular flags; you can change the default action on double click... |
| 07:19 | < Reiver> | Still a number of things I haven't removed - it only brings up Winamp-related options when you click it. But it'll do |
| 07:19 | < Reiver> | ... -.^ |
| 07:21 | <@Vornicus> | Lots, and lots of cool things to do in there. |

| 11:05 | | * gnolam ponders blurred lines in OpenGL. |
| 11:07 | <@Vornicus-Latens> | There's multi-pass blur filters, you'll want to turn on AA on the lines though. |
| 11:07 | <@Vornicus-Latens> | And have a very small blur aperture, or you'll just get a mess |
| 11:13 | <@gnolam> | Line AA as in GL_LINE_SMOOTH? |
| 11:13 | <@Vornicus-Latens> | iirc, something like that, yes |
| 11:13 | <@Vornicus-Latens> | Sleptime |
| 11:15 | <@gnolam> | Because that... does not produce the effect I want. |
| 11:15 | <@gnolam> | In fact, it doesn't seem to do /anything/. |
| 11:15 | <@gnolam> | Or hmm... I may have forgotten glHint(). |
| 11:16 | <@gnolam> | No, I hadn't. Damn. |
| 11:21 | <@gnolam> | Ahh! You had to enable blending. |
| 11:36 | <@gnolam> | Now I just have to get the segment melding working... |
| 11:42 | <@McMartin> | Use line strips instead of individual lines? |
| 11:44 | <@gnolam> | I already am, to the extent the map info allows me. |
| 11:44 | <@gnolam> | But I believe it can be taken further. |
| 11:46 | <@gnolam> | (It's the segment switching that kills performance) |

| 20:44 | < Janus> | Finally come up with a way to determine if a line is connecting with a sphere! (I think.) |
| 20:45 | <@Vornicus-Latens> | "connecting with"? |
| 20:45 | <@Vornicus-Latens> | The usual way is to get point-line distance, which is a simple-ish formula |
| 20:46 | < Janus> | Yeah, going through it. (Don't tell me the answer yet! I wanna see if I got it right first~) |
| 20:47 | <@Vornicus-Latens> | heh |
| 20:50 | < Janus> | See if either ends of the line are inside of the sphere by compare the distance from the center, then check to see if "line_length* tan(theta/2) <= sp_radius" Where theta is the angle from one point of the line to the other from the sphere. |
| 20:51 | | * Vornicus-Latens ponders |
| 20:52 | <@Vornicus-Latens> | I don't think that actually works. |
| 20:52 | <@Vornicus-Latens> | No, it doesn't |
| 20:52 | < Janus> | Er... "if((length/radius) <= tan(theta/2))"? |
| 20:53 | <@Vornicus-Latens> | No, see, the thing is |
| 20:53 | | * AnnoDomini is trying to grok that. What do you mean by 'connecting with'? |
| 20:53 | <@Vornicus-Latens> | the right measure is along a perpendicular to the line, not along the bisector of the angle |
| 20:53 | <@AnnoDomini> | Like a wossname... tangent? |
| 20:54 | < Janus> | Well... I divided the theta by 2, because it's undefined at 90 degrees, and one at 45. |
| 20:54 | <@Vornicus-Latens> | http://mathworld.wolfram.com/Point-LineDistance3-Dimensional.html <--- down at the bottom. |
| 20:59 | < Janus> | I figured... with a unit circle radius 1, and a line unit long, "(1/1) <= tan(90/2)" worked out graphically, as it was a line that clipped the outer edge of the sphere. I should have tested it with other angles first... |
| 21:01 | < Janus> | ... wait. |
| 21:02 | <@AnnoDomini> | Hm. So taking that formula (for d), it would be... if d == 0 for X and d != 0 for X+epsilon and X-epsilon, where epsilon is a small positive, then the line would connect with the sphere. |
| 21:03 | <@AnnoDomini> | Or something. |
| 21:03 | <@AnnoDomini> | Actually, substitute 0 for R, the radius. |
| 21:06 | < Janus> | Such high math. Or, at least, math with funny words sprinkled about. (The line's length needed to be doubled, now that I look at it. Though, that shouldn't matter too much) |
| 21:06 | < EvilDarkLord> | Hello, peoples. Would someone know the formula for getting the angles of a triangle on a sphere, given the latitude and longitude of each point? |
| 21:07 | <@Vornicus-Latens> | http://mathworld.wolfram.com/SphericalTrigonometry.html <--- have fun. |
| 21:08 | < EvilDarkLord> | Cheers, I think. |
| 21:08 | < Janus> | Haha, I hope they have something useful for cylinder/line collisions in there, somewhere~ |
| 21:09 | <@Vornicus-Latens> | http://mathworld.wolfram.com/Line-LineDistance.html |
| 21:09 | < Janus> | Hot gravy, I'm set then! |
| 21:10 | | * AnnoDomini notes that in his interpretation of the line problem, X is a point along the line. |
