A month ago (wow, I am really slow to update this blog ...) I went to the 34th EurOpen.CZ conference. I did a presentation about Git (paper, slides).
The first day the weather was pretty good and we even went to Praděd summit to take a few snapshots of the setting sun. The next day was rainy so I set up my dance pads and we had a lot of fun playing DDR in the evening. One of the most interesting things there was Microsoft Surface, which is in fact an overweight PDA (weighs about 90 kg). It is pretty addictive, especially for children. Microsoft can really make a pretty cool hardware. However, it is in some way a bit, well, Microsoftish :-). For example, they apparently invented their own 2D barcodes, ignoring well established standards like QR code or Semacode. Also, apparently the external keyboard and mouse is required to boot the Surface.
There were many interesting presentations: Tomáš Košnar talked about logging the network traffic, Ondřej Surý had a brief intro to DNSSEC, Václav Pergl from Kerio Technologies talked about agile development, etc. Anyway, AbcLinuxu.cz did a report from the conference, and also (oh, horror!) an interview with me, mostly focused on Git.

How Do I Install ... ?
The funniest page of the day is the page with installation instructions for OpenAIS. But seriously, do you have experience with those clustering suites?
My task is pretty simple: use a clustered LVM from two hosts. I have been using Heartbeat for my HA clusters (and IPVS for load balancing) for ages, but apparently Heartbeat-based cluster cannot be easily used for CLVM.

OK, after another half a year we now have a new Fedora. I have installed it on my laptop, and found no obvious bugs. It "just works". I haven't got time to read the Release Notes yet, but so far F11 looks good. The minor issues are:
gnome-terminalnow wants to confirm the window closing when something other than the original shell is running inside it. WTF? I guess users are getting more and more stupid and have to be protected from their own stupidity (or maybe Fedora/GNOME is becoming more and more widespread). The only usability problem with this "enhancement" is that it cannot be disabled from the Preferences menu - one has to resort to using
gconf-editor, which is not even installed by default.
- Cpufreq on ASUS F3E still does not work (but then, I use my own kernel on F3E and in vanilla it works).
- A nice surprise is that with F11 and its new X.org + WINE, the "In the Groove" game finally renders correctly (in the previous version all the arrows were rendered orange, which made the gameplay more confusing).
- The new boot splash screen is not so minimalistic than the one from F10 (which I consider to be the best boot splash screen ever; its neat visual trick with colors in the progress bar made the boot process feel faster).
- GRUB still
does not support ext4, which means that even those who want a full ext4-based
system need to have a small ext3 partition for
Of course, I now have tens of mails from the bugzilla bot forewarning about
closing bugs filled against F9, which I need to test on F11. I guess
many of the
gdm >2.20 regressions are still not fixed,
and returning 2.20 to the Fedora (at least as an optional package)
is long overdue.
