Downgrading from KDE 4 to KDE 3

I have been using KDE 4 for some months now, but a couple of days ago it simply could not take it anymore. It simply unbearably slow on some crucial things like ALT-F2, and to add insult to injury, everything seems to be made more gnome-ish but more unusuable. The last straw was trying to add a launcher for Opera onto the main panel, and ending up instead with my KDE menu un-moveable on the right edge of the main panel next to the clock (I will skip the details). So, downgrade time! I had installed the KDE 4 packages from the experimental repository and had added an entry to the /etc/apt/preferences, so that packages once installed from experimental would be included on apt-get upgrades, like this:

Package: *
Pin: release a=experimental
Pin-Priority: 101

A quick Google reminded me of how to downgrade in Debian: I added an entry for the normal unstable with an elevated priority:

Package: *
Pin: release a=unstable
Pin-Priority: 1001

And after that, it was a simple matter of cycling through apt-get (dist-)upgrade and apt-get -f install until all packages where downgraded and their dependencies resolved. A apt-show-versions -b |grep /experimental provided me with a list of packages that remained to be removed manually. Finally, I had to apt-get install kde-base to have the KDE choice in KDM again, and I had my old KDE back- even the config remained intact, KDE 4 on Debian uses ~/.kde4. The only thing I miss is Dolphin and the nice integration on removable media.

Still cold

Nothing much happened- the snow thawed a bit (I wonder why, it has never been above zero degrees as far as I can see) and then froze again, with -14 degrees today- so everything is really icy and slippery. Sorry for the reappearing pictures, stupid subversion (rename=delete+readd) + stupid user who forgot that. There is a new post that was causing the broken blog (now 'fixed') before them.

Bagels in Space

brrr Winter ist da! Und wie: -18 Grad Celsius sagt das Thermometer- dabei knallender Sonnenschein und fast kein Wind- also nicht so schlimm wie es sein koennte. Gestern hat es auch zum ersten Mal geschneit. Die mitgebrachte Kleidung hat sich bisher als ausreichend herausgestellt, einzig eine Maske fuers Gesicht werde ich bei Wind wohl noch kaufen :) Heute Mittag war ich mit Nicolas im Eaton-Center-Food-Court, danach einen Espresso Macchiato (mit Latte Art) in der Downtown-Filiale von Art Java - die sich direkt in der Naehe des McGill Campus befindet (oh oh, schon mein dritter Besuch nach zweien am Wochendende in der anderen Filiale). Am Wochenende habe ich mich die meiste Zeit im Plateau und im Mile-End rumgetrieben, versucht recherchierte Laeden zu finden und andere entdeckt. Ich war im Café Olympico und in den verschiedenen Bagel-Shops. Es gibt unzaehlige Cafés und Second-Hand-Buecherlaeden hier, und ich habe mir Cryptonomicron gekauft um es diesmal wirklich durchzulesen. Nachdem ich eine moegliche zukuenftige Bude (die momentane hab ich nur fuer Dezember) besucht habe, hab ich meinen ersten Film entwickeln lassen - am Sonntag, in einer Stunde, ich konnte ihn noch um 17h abholen UND die Scans haben eine hohe Aufloesung. Und schliesslich: meine Versuche im Franzoesisch-Sprechen werden immer oefter auch beantwortet- wenn man zoegert oder nachfragt, wird sofort auf Englisch umgeschaltet und man hat seine Chance vertan.

Weather, Food + Internet

Weather: After my first day to the university I immediately started feeling a cold coming up- seems the climate is really something to adapt to. The first days were cloudy and much like the weather back in Bielefeld, but today we had blue sky, with temperatures falling below zero again and a bit of snow falling on the way home.

Food: At lunchtime, I had to face the problem of getting food in the University for the first time- the on-campus food is apparently really bad and everyone brings their own food or goes to a restaurant. On Wednesdays (my first day), the SRL group orders Thai food from "Cuisine Bangkok" (yum!). The only one really nearby is a Libanese fast food shop, so I went there and had couscous with vegetables- yum. This will burn my money fast, I fear.

Internet: The long way home:

From the university (ssh feels sluggish)

Arrived in Montreal

I arrived in Montreal on Monday. I am here for a research stay at the shared reality lab until the end of February. I will be getting to know the different projects of the group and decide on the topic of my diploma thesis. If you are in Montreal or have any hints on what to visit, where to drink coffee etc. please contact me!

Zattoo on Debian Unstable - Or: what are you typing all the time?

This week I got my new laptop (rented from the University), a Dell Latitude D630. Almost everything worked right out of the box with Debian Unstable, only the Hotkeys are not working yet. I guess thats the price for not choosing Ubuntu :). I tried to install Zattoo (Sunday is Tatort-day), but it failed because it depends on libxul0d, which is not included with xulrunner 1.9 in Sid. After setting up a pbuilder environment and a local Apt-Repository with Reprepro, building xulrunner 1.8 from Ubuntu Hardy was a matter of waiting some minutes (2x2.2 Ghz + 4 Megabyte cache :). I love pbuilder. After adding the compiled results and the Zattoo binary-package into the repository, apt-get install zattoo installed the package and its dependencies. Zattoo started and logged in, but complained about missing the Adobe Flash plugin, which was installed (flashplugin-nonfree) and segfault'ed after buffering. This could be fixed by linking /usr/lib/flashplugin-nonfree/libflashplayer.so to /usr/lib/xulrunner/plugins.

My K750i and Linux

First post in english, maybe its of some use for somebody else.

I finally got around setting up backups of my Sony Ericsson phone again. First, I added an udev-rule to fix the permissions of the /dev/rfcomm0 device which gets set up automatically by Gentoo if configured right.

/etc/bluetooth/rfcomm.conf

 rfcomm0 {
  # Automatically bind the device at startup
  bind yes;

  # Bluetooth address of the device
  device 00:AA:BB:CC:DD:EE;

  # RFCOMM channel for the connection
  channel 1;

  # Description of the connection
  comment "description";
 }

udev-rule
```
 KERNEL=="rfcomm[0-9]*",GROUP="dialout"
```
Now we can access the phone via /dev/rfcomm0 as soon as we turn on bluetooth and plug in the adapter.

I tried some applications with this:

Gammu: this Gnokii-Fork also supports non-Nokia phones. There is a good GUI available (wammu), but I wasn't so lucky so I sticked to plain gammu.
- ~/.gammurc:
```
[gammu]
connection = at
port = /dev/rfcomm0
logfile = gammulog
logformat = textall
```
- A backup of the whole phone can be done with:
```
gammu backup <filename>
```

This will dump everything in one file.

OpenSync: this is the successor of MultiSync, the GUI for it did not build for me, but the commandline client msynctool does work. First, I tried a group of syncml for the phone, kdepim for Kontact and file for something 'solid' ;), like this:

Configuration was pretty easy once I figured it out:

# create group
msynctool --addgroup jan_private
msynctool --addmember jan_private kdepim-sync # -> member 0
msynctool --addmember jan_private file-sync # -> member 1
msynctool --addmember jan_private syncml-obex-client # -> member 2
# discover capabilities
msynctool --discover jan_private 0
msynctool --discover jan_private 1
msynctool --discover jan_private 2
# disable everything beside contacts
msynctool --disable-objtype jan_private event
msynctool --disable-objtype jan_private note
msynctool --disable-objtype jan_private data
msynctool --disable-objtype jan_private todo

Config for the plugins:

kdepim has no options

File: msynctool --configure jan_private 2

  <directory>
    <path>/home/ja/docs/sync</path>
    <objtype>contact</objtype>
    <objformat>vcard30</objformat>
  </directory>
</config>

SyncML (see OpenSync wiki): msynctool --configure jan_private 3

<?xml version="1.0"?>
<config>
  <bluetooth_address>00:AA:BB:CC:DD:EE</bluetooth_address>
  <bluetooth_channel>8</bluetooth_channel>
  <identifier>Sony Ericss</identifier>
  <version>1</version>
  <wbxml>1</wbxml>
  <username></username>
  <password></password>
  <type>2</type>
  <usestringtable>0</usestringtable>
  <onlyreplace>0</onlyreplace>
  <onlyLocaltime>0</onlyLocaltime>
  <recvLimit>0</recvLimit>
  <maxObjSize>0</maxObjSize>
  <database>
     <name>Contacts</name>
     <objtype>contact</objtype>
     <objformat>vcard21</objformat>
   </database>
</config>

Now we can sync (I need to try twice so it does the slow sync):
```
msynctool --sync jan_private
```

This gave me a duplicates everytime I synced.

Since it was a long time since I used my old addressbook, it took quite some time to hand-merge the backuped contacts (one for each number - wtf sony?) with the two other addressbooks (in Kontact). After that, I deleted all my contacts on the phone, tried - and it fucked up, because there were all the duplicates still in the file-backend. Ok, new group, only kdepim and syncml in it, delete all contacts on the phone again, sync - and everything is nice. Even syncing seems to work. Only Kontact doesn't show the Names of new synced contacts until you save them again.
