May I ask a small question in the form of a picture?
05:19
< Janus>
I should have asked that in picture form too. Whoops! http://dl.dropbox.com/u/3108480/whatamieven027.png I wanna do a thing that looks like this, but I don't know what that would be called.
05:20
<&Derakon>
Well, first off the "math things" are edges. :)
05:21
<&Derakon>
So you have a graph and you want to be able to grab nodes on the graph and drag them around, but after you let go of them they slowly move back to...what?
05:22
<&Derakon>
Their original location? A position as defined by their neighbors?
05:23
< Janus>
Um, I suppose the original location! ... or maybe the neighbor. I'm not sure which would work best yet. I wanna do 2D fabric soft simulation stuff with it.
05:25
<&Derakon>
I really suggest then that you look up fabric algorithms.
05:25
< Janus>
Nothing fancy or even robust. Just something to help me animate certain things on sprites, like dresses and hair. It'd only have to respond to wind, movement, and whatever bodyparts they are attached to
05:25
<&Derakon>
I mean, you can try to figure out something on your own that might kinda work, but people've been working on this stuff for decades now.
05:26
<&Derakon>
Ah.
05:26
< Janus>
Oh, they have? I only ever found stuff for 3D. I can try looking harder, aha. I was gonna do just that once I figured out what the right words to search with were
05:26
<&Derakon>
I wouldn't be surprised if you could omit a dimension without loss of utility.
05:31
<@ToxicFrog>
Also, the singular of "vertices" is "vertex"
05:33
< Janus>
... whoops! I didn't know that.
05:35
<@ToxicFrog>
You might be able to do something using joints and forces in box2d, but there's probably one or more specialized libraries for this somewhere.
05:35
<@ToxicFrog>
(although if you're using box2d anyways...)
05:40
< Janus>
Oh I'm using it! I don't know if it'd work very well though. The fabric thing would be for very small sections on small sprites, and I've had box2D flip out when I go overboard with joints, aha. 6 wheel joints I have discovered is the hard limit
05:41
< Janus>
Well, not hard. But stuff starts fibrating violently, then rocketing towards the sky like a glitchy tiger in skyrim
05:49
< Janus>
Like the faulds on this sprite. http://dl.dropbox.com/u/3108480/10percentdonebleh.png It'd only need to be one solid colour, so long as it didn't let the legs clip through.
05:51 * Janus would have to turn the resulting shape through something to make the sillouette appealing anyway
06:01
<&Derakon>
Honestly it seems to me like it'd be easier to just hand-animate the cloth.
06:02 * Janus is pointed to he wikipedia article on Verlet Integration. Fragments of his head are found across the countryside.
06:06
< Janus>
I'm starting to think that too, sadly. Hair and cloth are ginourmous pains to animate though. Takes me about 2 hours to do just 5 or 6 frames. For small things! Large things like those faulds, or really long hair, take much longer, and need twice as many frames. Not because there's a lot of work perse. Just a lot of tuning and retuning

WOrse, he's loaded DBI, and is constructing SQL queries by hand, no prepare(), doing on validation on the messages, and he's talking to DBD::mysql directly. I whish I knew where this guy hung out, this thing is a big, flashing "Please screw with my database!" invitation

12:14
<@Tamber>
Naturally.
12:18
<@TheWatcher>
(you can't use END { } blocks, as it simply nukes the package symbol table and frees the memory >.< - you need to implement 'sub can { my $self = shift; my $op = shift; return $op eq "UNLOAD"; } sub UNLOAD { ... } as far as I can tell)
12:19
<@TheWatcher>
Yep, that's the trick
12:20
<@TheWatcher>
SO, I should be able to persist database connections, anyway
12:24
<@TheWatcher>
of course, there's the "what if the db goes away" issue. I guess this needs to be done in addition to text logging, and I'll need to write something to fix up missing data from them (which I'll need anyway to import all my old logs)

Not anymore :)
21:58
< maoranma>
I setup mIRC a while ago to make nicks that are idle for hours to turn the same color as the background, and others change to various shades from green to red
21:59
<@Ling>
Red meaning our silence kills us?
21:59
< maoranma>
And I made a script that when someone talks and they aren't assigned a color in my address book for messages, it randomly assigned one that isn't white or black
21:59
<@Ling>
I like the idler script though, that sounds cool
22:01
< maoranma>
it's not a script, just a function of the mIRC nicklist, because it maintains the IAL better than I could emulate with a script. I'm sure there's an elegant way to make it a script, but meh. I could write an alias that does the necessary nicklist changes one time though

Probably should have implemented some kind of fuzzy match, so small changes in hostmasks over multiple logins would hopefully be reconciled to the same user

Well, there are some mask types in mirc, so something like *!ident@*.domain.com

So similar idents and domains get consolidated

Hmm. Yeah, I hadn't used idents, just hosts

It was something I whipped up at, like, fifteen, as a little project to learn mIRC's scripting language

Yea, $mask(X,3) *!*user@*.host

Hrm, can someone say something, I need to check if I'm inserting these signals right...
23:50
<@ToxicFrog>
Mrr?
23:51
<@TheWatcher>
Well, blegh, it looks like the nick data sent to 'message public' doesn't include op status, hohum, I can pull it out of the channel I guess
23:51
<@TheWatcher>
Thanks anyway
23:52
<@ToxicFrog>
It doesn't?
23:52
<@ToxicFrog>
Say something.
23:52
<@TheWatcher>
Something.
23:53
<@ToxicFrog>
Oh, so it doesn't.
23:54
<@TheWatcher>
$server -> find_channel($target) -> nick_find($nick) -> {prefixes} should be enough (or op/halfop/etc in the Nick object)
23:55
<@TheWatcher>
*channel_find
23:59
<@TheWatcher>
Yep, that does what I need, excellent.
