12:23 -!- Irssi: #t2: Total of 12 nicks [1 ops, 0 halfops, 0 voices, 11 normal]
12:52 < koan> rxr: are you running T2 on your Acer Aspire One?
12:53 < CIA-22> rene * r31686 /trunk/package/develop/valgrind/valgrind.desc: * updated valgrind (3.3.1 -> 3.4.0)
13:04 < rxr> koan: nope, I was only typing on the one on a christmas day
13:05 < rxr> I'm waiting for a useful Apple sub-notebook (like a thinner 12" PowerBook) for years (yes, the crippled and not so useful formed MacBook Air doesn't count :-)
13:05 < rxr> due to lack of "real quality hardware" I keep my eye on the HP mini 1000 or Lenovo Ideapad
13:05 < rxr> but the mini is still not available in Germany (sigh) and the Ideapad as a strange keyboard layout in Germany ... :-(
13:06 < rxr> so I'm still eying possible devices
13:06 < rxr> for me it must have a > 10" screen
13:06 < rxr> 8.x" is way to small for serious typing
13:11 < koan> I have bought a AA1 and I like it for my occasional trips
13:12 < rxr> linux running already?
13:12 < rxr> I mean there should not be anything in the way to just run T2
13:12 < rxr> koan: did you got the 8" or 1x" flavor ?
13:12 < koan> maybe I'll install T2 on it, I have now Ubuntu on it, but that's too bloated, especially on this sort of machine
13:12 < koan> the 8.9", 512 MB RAM, 8 GB SSD
13:13 < koan> this was the only model I could buy in Belgium without being forced a Windows license :-(
13:14 < koan> btw, if I want to build T2 for it, what optimalisation should I use for the Atom processor? is this i686?
13:15 < rxr> it can even run 64bit code IIRC
13:17 < rxr> so in theory core2 with -Os
13:18 < koan> hm the Diamondville in these netbooks is purely 32 bit, according to Wikipedia
13:18 < rxr> oh - really?
13:18 < rxr> I thought they have 64bit and the VT
13:19 < koan> the desktop ones, yes
13:19 < rxr> I have the dual core Atom 330 in a server, but I do not run y 64bit kernel due to just re-using the old server install ...
13:20 < rxr> Instruction setx86, x86-64
13:20 < koan> http://ark.intel.com/cpu.aspx?groupId=36331
13:20 < rxr> x86-64 is so far only activated for the Atom 230 and 330 desktop models
13:20 < koan> this one has no VT and no x86-64
13:20 < rxr> oh
13:21 < rxr> I thought all Atoms would include 64bit instructions
13:21 < rxr> what a mess Intel made out of the marketing names yet again
13:21 < koan> indeed
13:21 < koan> so which optimization could I use for this N270 then?
13:22 < rxr> -march=prescott -Os # maybe
13:22 < koan> ok I found this on gentoo: http://en.gentoo-wiki.com/wiki/Safe_Cflags/Intel#Atom_N270
13:23 < rxr> strange Gentoo lists Os for the 330 and O2 for the N270
13:23 < rxr> guess just random thoughts of Gentoo users
13:23 < koan> :-)
13:23 < rxr> in projects I found Os generally preferable for "tiny" / "low-end" CPUs with "not too much cache"
13:25 < rxr> but actually, for some "should run everywhere" project I just use 686 + Os for some auto-updated seed that is intended to theoretically just run on every "reasonable" silicon of the last decades"
13:25 < koan> is the difference noticeable?
13:25 < rxr> this has the benefit to just swap boards / backplanes and to continue to run the software no matter what manufactor it is
13:26 < rxr> I found the difference only notivable in security (encryption), compression and multi media / graphic / audio stuff
13:26 < rxr> because in tight loops massively number crunching it can differ upt o 2-8 times of higher performance
13:27 < rxr> but some of the key packages, such as ffmpeg, have multiple assembly code paths that are run-time selected anyway
13:28 < koan> ok
13:31 < CIA-22> rene * r31687 /trunk/package/develop/git/git.desc:
13:31 < CIA-22> Martin Papadopoulos :
13:31 < CIA-22> * updated git (1.6.0.4 -> 1.6.0.6)
13:36 < CIA-22> rene * r31688 /trunk/package/base/mkinitrd/mkinitrd.sh: * added ext4 to the initrd embedded filesystem kernel modules
13:38 < CIA-22> rene * r31689 /trunk/package/base/mkinitrd/mkinitrd.sh:
13:38 < CIA-22> Martin Papadopoulos :
13:38 < CIA-22> * added kernel modules to the kernel initrd required to boot from to
13:38 < CIA-22> boot hp smartarray and ibm serveraid controllers
13:45 < CIA-22> rene * r31690 /trunk/package/network/ntp/ntpd.init:
13:45 < CIA-22> Martin Papadopoulos :
13:45 < CIA-22> * improved ntpd.init to set the clock to a sane value before daemonizing
13:48 < CIA-22> rene * r31691 /trunk/package/gnome2/gail/:
13:48 < CIA-22> Martin Papadopoulos :
13:48 < CIA-22> * removed gail, obsolete according to http://www.gnome.org/ ...
13:48 < CIA-22> * as a side effect this fixes shared files with gtk+ et al.
14:08 -!- mpp [n=mpp@i53875693.versanet.de] has joined #t2
14:25 < CIA-22> rene * r31692 /trunk/package/emulators/kvm/ (7 files): * updated kvm (81 -> 82)
14:28 < rxr> hi mpp
14:29 < mpp> moin moin rxr
14:29 < mpp> :-)
14:29 < mpp> i'am excited to see kvm beeing patched
14:29 < mpp> i'll give it a try with trunk
14:29 < mpp> btw. the 2.6.28 breaks with the aufs patch
14:30 < mpp> on the nr_cpus matter i checked the git repo of ther kernel - seems to be some changes for more than 8 cores coming our way
14:30 < rxr> the shared kvm.h is still not addressed ....
14:31 < mpp> :-(
14:31 < rxr> you could easily just ignore it as well :-)
14:31 < mpp> but it's okay for now - virtualbox does work on trunk
14:31 < mpp> ah k
14:31 < rxr> (or I patch the installation fo it away for the time being)
14:32 < mpp> i would say to have it complain about the shared file rather then suppress it
14:32 < mpp> i have discovered another curious thing regarding xorg-server on trunk
14:32 < rxr> well - for an error-less build one occurance has to be suprressed
14:33 < mpp> if you build the repo (besides the xkeyboard-config)there seem to be no shared file - but ...
14:33 < mpp> the font-misc-misc and font-cursor-misc packages need to be rebuild to have the x-server running.
14:34 < mpp> i'll investigate this next week to see why and how . same goes for dbus + dbus-glib + hal
14:34 < mpp> allthoug they all build fine on the target system they need to be recompiled ...
14:34 < mpp> no shared files though...

15:22 < mpp> hey rxr
15:23 < mpp> i have a git version of fluxbox on dl2+dl3
15:23 < mpp> fluxbox could use an update - some annoying bugs where fixed
15:23 < mpp> and since t2 has no git checkout i packed the git version to a tarball
15:31 -!- DigitalOktay is now known as digitaloktay
15:43 < koan> rxr: what does "The use of custmain is deprecated, please use hooks instead" mean?

18:37 < rxr> koan: that the package is using 'custmain' "main" function
18:37 < rxr> and should be converted to use more fine grained hooks
