[05:40:32] <KimK> KimK is now known as KimK_
[05:41:28] <KimK_> KimK_ is now known as KimK
[13:03:09] <jepler> micges, cradek: you both agreed with me that we should go with back-ported C arcs for 2.4. Have either of you had a chance to test http://emergent.unpy.net/files/sandbox/axis-c-arcs.mbox ?
[13:03:23] <cradek> yes no
[13:04:49] <cradek> I'll try to do it today
[13:05:03] <jepler> I'd appreciate it
[13:05:50] <jepler> I'd like to push it today or tomorrow, as I'll have limited internet and no time to develop emc for the next couple of weeks.
[13:05:59] <cradek> ok
[14:12:48] <jepler> here's another difficulty for anyone who would like to extend gcode to elliptical arcs: the offset of an ellipse is not an ellipse; it has u^3 and u^4 terms in it. http://www.freesteel.co.uk/wpblog/2006/12/the-offset-ellipse/
[14:16:34] <cradek> wild
[14:18:00] <SWPadnos> yeah. it's not immediately obvious that a bigger ellipse isn't right, maybe because it is right at the axis intersections
[14:44:00] <alex_joni> http://kernelnewbies.org/Linux_2_6_30#head-06ffa8309b7871ea91f182719e6ca7d5146dda00
[14:45:18] <jepler> yeah, a proposed offset ellipse a+t,b+t is right at 4 points, but I guess it's intuitive for me that it's wrong at all other points
[14:45:46] <jepler> alex_joni: are you calling attention to the comedi drivers, or something else?
[14:46:26] <jepler> I think it would be excellent if someone contributed a hal realtime driver that could use arbitrary comedi driver(s)..
[14:56:26] <alex_joni> COMEDI drivers
[14:56:35] <alex_joni> they are now mainline in 2.6.30, albeit in the staging dir
[15:42:44] <jepler> luckily(?) for me I don't have any comedi-compatible hardware except maybe that horrible PCI 8255 card that just crashes my system when I try to use it
[15:48:35] <SWPadnos> I wonder how one would load a HAL driver that could use arbitrary COMEDI drivers
[15:48:47] <SWPadnos> ie, how to specify which device(s) to use
[15:49:03] <jepler> I dunno; with some kind of terrible insmod parameters, I assume
[15:49:19] <SWPadnos> yeah. it might make me have nightmares if I think about it much
[19:55:01] <aystarik> 10.04 beta is out...
[20:41:41] <alex_joni> SWPadnos: maybe it could look at loaded modules, discovered hardware and capabilities
[20:42:21] <SWPadnos> even if it's possible to look at everything that's there, that doesn't describe how to set things up or what to call them
[20:57:47] <alex_joni> wtf http://www.webupd8.org/2010/03/and-reason-why-metacity-window-buttons.html
[20:59:25] <alex_joni> SWPadnos: we could use clsid's for the names.. (e.g. 92396AD0-68F5-11d0-A57E-00A0C9138C66)
[21:00:21] <SWPadnos> where/when are those generated?
[21:03:49] <alex_joni> SWPadnos: obviously I was joking
[21:04:05] <alex_joni> but they are created using a combo of loaded drivers and hardware
[21:04:14] <SWPadnos> heh - I thought you were talking about a unique ID for the software, not a person
[21:04:23] <SWPadnos> I kind of re-thought that over time :)
[21:04:36] <SWPadnos> I don't think the drivers get loaded automatically
[21:04:55] <jepler> geez, that story could have been a lot shorter
[21:05:00] <jepler> "because that's how macs do it"
[21:05:14] <alex_joni> not quite, but close
[21:05:28] <SWPadnos> there was something in the example programs saying that you had to be sure you had set up the device driver correctly for the device file you want to use (userspace programs obviously)
[21:06:06] <alex_joni> What OS X has: close, minimize, maximize : menu
[21:06:06] <alex_joni> What we have: maximize, minimize, close : menu
[21:06:06] <alex_joni> What Windows has: menu : minimize, maximize, close
[21:07:23] <alex_joni> (one thing I like about windows is that for a maximized window the close button gets activated at top-right screen location)
[21:07:47] <alex_joni> so I don't have to aim the mouse to close the window.. just jerk it right/up and close it
[21:07:50] <jepler> oh, I forgot, you people with standard ubuntu panels lost that years ago
[21:08:13] <jepler> though who uses the mouse for any of those activities anyway
[21:08:34] <alex_joni> heh
[21:11:45] <jepler> with close outermost, then you can probably get "corner to close" behavior if you get rid of the top bar. But that's OS X order, and I don't think you can get rid of the bar there..
[21:13:21] <SWPadnos> there is a step-by-step guide for making the Ubuntu UI look and act very nearly exactly like OSX
[21:13:34] <jepler> oh, that's a short one too
[21:13:39] <SWPadnos> including putting the application menu on the top panel, adding the search (spotlight), etc
[21:13:40] <jepler> 1. you bought a mac already, didn'
[21:13:42] <jepler> t you
[21:13:46] <jepler> 2. so just boot OS X, not Linux
[21:13:50] <SWPadnos> heh
[21:14:01] <SWPadnos> I'm not mac compatible ;)
[21:15:11] <SWPadnos> they even made the boot and login screens look the same, as well as using the same default background
[21:24:09] <alex_joni> just use fvwm95 already
[21:28:57] <cradek> isn't button location one of the things you can affect with themes in gnome?
[21:29:36] <jepler> cradek: yes, afaik
[21:29:37] <alex_joni> cradek: I think you can.. people are just bitching that the default theme changed
[21:30:32] <alex_joni> there's 900 of him already?
[21:35:00] <SWPadnos> only 899 now
[21:37:45] <jepler> you'd better have a good reason to change things like that; not "we might want to put something on the right in the future (but we won't say what)"...
[21:38:24] <cradek> yeah, what a way to handle it
[21:39:10] <jepler> * jepler <- certified change hater
[21:45:34] <alex_joni> change with good reasons is sometimes acceptable
[21:45:45] <alex_joni> without reason it's just bogus
[21:53:41] <SWPadnos> ah, here we go: http://news.slashdot.org/comments.pl?sid=1591162&cid=31573450
[21:53:52] <SWPadnos> I think that sums it up for a lot of people :)
[21:58:15] <cradek> waaaahhh
