new EMC 2.0.1 packages in the ubuntu repository
someone should announce 2.0.1 on the website
I already nominated chris to do that
I think I'm in turn nominating alex
oh, you mean the linuxcnc site?
yeah, thats definitely alex
or maybe SWPadnos
* jmkasunich doesn't do joomla
I was talking about the SF main page
I meant the linuxcnc.org website
cdrecord: WARNING: Data may not fit on current disk.
cdrecord: Notice: Use -overburn option to write more than the official disk capacity.
how big is it?
err - I
that is kinda big
I thought a CD was 700 and "a few" meg
that's the same size as the version I got on bittorrent
err - I'm not exactly sure how to go about updating the linuxcnc.org site, to be honest
but the md5sum is right
I burned it with nautilus-cd-burner or whatever it's called, and got no warning.
jepler: that doesn't work with my old burner
probably because nautilus is the "user friendly" burner
SWPadnos: I know it has something to do with those buttons that have rounded corners
crap, I can't burn it
cradek: remind me tomorrow morning that I could have brought you a copy, but forgot it at home instead.
if it were a *real* unix, I could install from dat tape
cradek: I know you're just trolling, but the fact that you can't is more about the limitations of the IBM PC BIOS than anything else.
(maybe I'm mistaken and there is a way for SCSI to load a boot block from tape)
sure, can't boot from it, but it could install from it with a floppy
anyway, I challenge you to produce an ubuntu live cd
actually I'm pretty sure freebsd can (could?)
er, live tape
[02:02:17] <cradek> http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/install-media.html
*ahem* and it's in text mode of course
I thought it was kinda cool that I could install freebsd with 3 floppies and a net connection
jmkasunich: it used to be with laptops that's often all you had
jmkasunich: actually redhat could do it too
I think they lost that capability now in fedora
I just don't run into many machines without a cdrom drive but with a 'net connection fast enough to download 1GB of RPMs
heh, surely that's another issue
if you're only going to download 10 megs and you have the equivalent of an early 1990s university's network, that's one thing
the compile farm is probably one of the few
but with the CD/DVD you have to download them whether you want them or not. surely a real network install is superior for that reason
it has a shared floppy for all 8 slots, the only way to get a cdrom is to pop the top and plug into a slot's IDE connector
cradek, until you do the 2nd install, the burned CD is much faster for multiples
besides any reasonable OS install is only a couple hundred meg right? that's 10 minutes download time
(now I'm trolling)
hmm, the dithered pwm isn't as bad as I thought
it has issues only when making a dramatic change in duty cycle, _and_ the new duty cycle is very close to either 0 or 1
"breezy" hosted in vmware took 2:30 "real" to rebuild the emc 2.0.1 deb
heh! fixed it
with ccache enabled, the second './configure --with-rtai=/usr/realtime-2.6.12-magma && make' took 1:12 real
I'm getting a lower hit rate than I expected from ccache
jmkasunich: when you come back I might want to talk about using this vmware stuff as farm slots
I'd like to do that
I tried once with qemu and wasted an entire weekend fskcing around
but if I vmware is faster....
I've already installed two guests and built emc2 on one of them
with 3 hours out for dinner with family
I have a dual P3-600 box I can dedicate to it
anyway .. next week we can talk about it
or maybe I can run it on my main box (rather not tho)
how fast is your hardware?
so still several times faster than my P3s, and probably a good bit faster than this box
this box = sempron 2200+, I think thats around 1.6G
feel free to mail me, I might be able to read mail in the evenings
I'll be back tuesday night (I hope)
don't let me keep you
an idle guest OS seems to take about 5% CPU, so you can't run all that many of 'em
but you can 'vmware-cmd suspend' and 'vmware-cmd restart' them so they're not going all the time
(from the host)
vmware server is pretty neat, clearly a whole different realm of product than qemu
if breezy wants to automatically update to dapper and that breaks realtime, we should probably include a bugfix for that in the .deb
it asks you if you want to upgrade to the new version, which most people will answer "yes"
breezy asks you to update to dapper? that's fucked up.
why'd we pick ubuntu again?
yes it does. and yes it is.
"just say no"
I hate everyone.
I didn't see that behaivor yesterday when I made the new emc2 packages
what? AFAIR it just said, there is a new version of ubuntu available, under the name of "dapper drake" or something like that
the update manager lets you know that there's a whole new version of the OS, not just updates to the stuff you already have
until today, the update manager just had bug and security fixes in it, so it was ok to let it do its thing
(I haven't seen it yet so I can't say too much)
It is an extra button - upgrade to dapper.
[18:40:47] <SkunkWorks> http://www.electronicsam.com/images/KandT/upgrade.png
anyway to 'downgrade'?
I doubt it
i'm looking at the ubuntu forums, and there are lots of problems...
I think they made a mistake putting that button there...
i'm probably going to reinstall breezy 'cause emc is all i use this machine for.
Roguish: no real way to downgrade
yeah, i doubt it also. i HATE the upgrade game.
I wonder why there isn't downgrade functionality, IIRC there is an apt-get update distro
it's not apt-put downgrade though ;)
dist-upgrade it's called.. but should be used with caution
alex_joni: can cause broken-ness?
has there not been a successful build of a 2.6.15 based RT kernel?
Lerneaen_Hydra: beyond fucked up
if I may say that
or is it the packaging that's the problem?
giacus compiled one IIRC
alex_joni: so really FUBARed then?
glad it was you
(or is there no problem? ;) )
SWPadnos: you certainly know what kind of testing there is needed
I guess it's kinda hard to make one kernel that will work on both distros, and still work for everything else (like udev / dbus / whatever else is needed on dapper, but not necessarily there on breezy)
I don't think that's the goal at all
there is no reason to use a newer breezy kernel
there may be features in dapper that require the newer kernel (though it's not that much newer, so there may not be)
yes there seems to be something wrong with the breezy kernel on dapper
I'm just saying we probably won't upgrade breezy kernels
the other issue is the perception of a downgrade, and the issue that the version number is lower and will probably require shenanigans to install
ok - multiple packages?
we're talking past each other here
yes I think both distribs should have rtai patches to the kernels they came with
* alex_joni assumes everyone in here is very deep into emc-developing
ok, so separate packages for each distro, which would render my points moot
so they can probably recompile emc2 and even a kernel (given enough nerves & interest)
but makes more ongoing work for the package maintainer
yes they'll be separate
only twice as much :-)
SWPadnos: even the maintainers :)
wouldn't seperate packages be a hell to maintain?
SWPadnos: got a dapper?
I think it'd be worse if one package had to deal with differences in the distribs.
I've got a dapper now
with issues/bugs in one but not the other, and differing names to keep track of and so on
cradek, that was what I was pondering before - it didn't look easy
SWPadnos: care to test?
I guess it's just the least undesireable outcome
SWPadnos: the udev difference we already ran into sure makes me nervous about sharing the packages.
ah - was ther eone? (I was just listing things that I thought could be a problem)
DBUS may also be an issue, since power management will be disabled
I ran into an interesting issue when reconfiguring the XOrg server in single-user mode
SWPadnos: I trust you figure out how to get emc2 for dapper
via package, or self-build?
alex_joni: yeah kinda
jepler: about to build an axis package
or not.. cradek knows something
he's going to tell you they might be compatible from breezy to dapper?
the odds are not bad, actually
hmm.. remembered I use gcc-4.0 not gcc-3.*
would that make any difference?
then probably not, there's C++ in there
you better build it then
but you'll notice right away if it doesn't work, because you'll get an ImportError when you run it
oops I should check that change in
sounds like the easiest way
you could apt-get -b source .. the same source should build real good
* alex_joni mumbles somehting about adding breezy repos
cradek: this isn't very fair.. you're making my life way too easy
so it just built with apt-get -b source?
running build-dep now
-b source now..
it builds just fine :D
hmm, you could have also done the emc2 deb that way
hmm.. apt-get -b source .. doesn't produce a source package
hmm.. libglib just updated on dapper
[Global Notice] Hi all. We just had a fairly route loss to one of our largest sponsors. We're back, and so far everything appears to be stable.
[Global Notice] Whoops, that would be "fairly large route looss".... thanks :)
