[00:13:17] <SWPadnos> hmmm. jepler, can you look at http://pastebin.ca/1457255
[00:13:52] <SWPadnos> that's on an up-to-date dapper install, with a very recent CVS (like last night)
[02:22:33] <jepler> SWPadnos: that's weird
[02:22:43] <SWPadnos> I thought so too
[02:22:49] <SWPadnos> python is 2.4.something
[02:24:09] <jepler> in other news, that pastebin is already indexed by google and is on the second page of hits for my search
[02:24:45] <SWPadnos> wow
[02:26:45] <jepler> does this work, or does it fail? python -c 'print "x-y".replace("-", "_")'
[02:27:36] <SWPadnos> it fails
[02:27:46] <jepler> your Python is extremely broken
[02:27:48] <SWPadnos> heh
[02:28:01] <SWPadnos> maybe I shouldn't have deleted that whole /usr/local tree :)
[02:28:33] <SWPadnos> I can reinstall python I guess
[02:36:46] <SWPadnos> hmmm. well reinstalling everything that starts with "python" didn't fix it
[02:37:07] <SWPadnos> now it may be time to uninstall then reinstall, but I fear there's a lot that depends on python
[09:04:37] <alex_joni> "I think white socks with black stripes are soo much better than blue socks with red dots"
[12:31:39] <jepler> alex_joni: I can't decide. perhaps I'll wear one of each
[12:31:44] <jepler> finally, a use case for having two feet
[12:48:35] <alex_joni> jepler: heh
[12:51:14] <SWPadnos> ha! I thought they were Cesium clocks!
[12:51:16] <SWPadnos> :)
[12:53:49] <alex_joni> "As a result, in 1967 the Thirteenth General Conference on Weights and Measures defined the second of atomic time in the International System of Units as
[12:53:52] <alex_joni> the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium-133 atom."
[12:54:24] <SWPadnos> see - that's why we have general conferences on weights and measuers
[12:55:00] <jepler> and yet they drag their feet introducing an exact integer value for Avogadro's number: http://arxiv.org/abs/physics/0612087
[12:55:12] <SWPadnos> who knew?!
[12:55:37] <jepler> It would also eliminate the need for the kilogram artifact altogether, since then, by definition, a kilogram would be exactly 1000/12 the mass of NA* atoms of carbon-12
[12:55:53] <jepler> ^^ it's like deleting an entire source file from the universe, and still having it work properly
[12:55:58] <alex_joni> http://upload.wikimedia.org/wikipedia/commons/e/e0/ChipScaleClock2_HR.jpg
[12:57:50] <alex_joni> jepler: heh
[12:58:40] <SWPadnos> but "1000/12 the mass of NA* atoms of carbon-12" is generated in the make process
[12:58:50] <SWPadnos> as long as you have the C-12 source
[12:59:54] <alex_joni> and the proper preprocess function
[13:01:35] <jepler> the problem with their definition is that 1000/12 NA*-atoms is not an integer
[13:01:44] <jepler> it would be nice if it were :(
[13:03:57] <jepler> oh, heh, I see that they get to that objetion on page 4
[13:04:56] <SWPadnos> but they're making those balls of silicon, not carbon
[13:05:11] <SWPadnos> so it will be 1000/28 (or whatever Si is)
[13:05:20] <SWPadnos> which is "even less" of an integer :)
[13:09:23] <alex_joni> jepler: how was my information incorrect?
[13:39:33] <jepler> alex_joni: "make" doesn't copy any nmlfiles around anymore
[13:45:28] <jepler> see r1.292 of src/Makefile
[14:56:37] <SWPadnos> huh. I must be missing an email from the user list
[14:56:59] <SWPadnos> I see JMK's reply to it, but not the email with the quoted text
[14:58:30] <skunkworks586> I did not get it either.
[15:02:07] <cradek> the birthday one? I got it.
[15:02:46] <skunkworks586> oh - so did it.
[15:02:47] <skunkworks586> heh
[15:03:12] <skunkworks586> it is in the last emc.nbl emails he sent
[15:03:38] <cradek> don't you guys have threading mailreaders?
[15:04:41] <skunkworks586> Yes - but I don't use it. I really should. (using thunderbird now and used to use outlook express)
[15:06:15] <SWPadnos> I only have two from Stuart, and "56" doesn't appear in either of them
[15:06:21] <SWPadnos> and yes, I use a threading mail reader
[15:11:03] <alex_joni> jepler: that's what I meant..
[15:11:17] <alex_joni> jepler: that it used to copy emc.nml around, and now doesn't anymore
[15:11:26] <alex_joni> probably didn't express it clear enough :/
[15:43:57] <jepler> sometimes my reading comprehension is bad
[15:47:21] <alex_joni> I'm sure it was a combination
[17:29:41] <SWPadnos> hey - there's Stuarts birthday message
[18:18:48] <alex_joni> SWPadnos: don't you love SF's promptness
[19:57:57] <Vortex2> Hello
[19:58:28] <Vortex2> Proplen whit servos foun
[19:58:49] <Vortex2> EMC did not had eny bug
[19:59:42] <Vortex2> Proplem was faulty clutch between servo and ballscrew
[20:01:28] <jepler> I'm glad you found the cause of your problem
[20:01:31] <jepler> thanks for the update
[20:02:34] <Vortex2> Other proplem is I need to make my own homing sequency
[20:03:43] <SWPadnos> see #emc :)
