non-distracting movie playback in kubuntu/vlc

For quite some i tried to find a way how to stop my screen (and projector) turning off during movie playback every 10 minutes. also i'm using the latest standard kubuntu, various googled solutions didn't help.
Now i found the solution: i added a 'xset s off' line to /usr/bin/startkde init script and everything is great now.
If you suffer from the same problem, please vote for the issue i have filled for the vlc player

making kubuntu use less memory

i run kubuntu on a 1gb ram netbook, and optimizing KDE memory usage is cruicial for me because i use this machine for development (kdevelop is a large beast, and i want to have chromium and gcc running as well). I'd like to share a few tips to achieve that.

1. sudo apt-get install kubuntu-low-fat-settings
2. if you don't need bluetooth: sudo apt-get purge bluez* bluedevil
3. sudo apt-get purge akonadi-backend-mysql mysql* (this will automatically install sqlite backend)
4. if you don't use activities: sudo rm /usr/share/kde4/services/kactivitymanagerd.desktop (i filled bug 298088 with request to make kactivitymanagerd ran only when really needed)
5. if you don't need akonadi: sudo rm /usr/share/autostart/akonaditray.desktop
6. if you don't use nepomuk (i.e. disabled it in systemsettings): sudo rm /usr/share/autostart/nepomukserver.desktop
7. sudo rm /usr/share/autostart/kaddressbookmigrator.desktop
8. if you don't use printer often: sudo rm /usr/share/autostart/printer-applet.desktop (you can still start this applet manually by issuing 'printer-applet' command in konsole)
9. sudo mv /etc/rc5.d/S50saned /etc/rc5.d/K50saned

(hint by Dave: instead of removing .desktop files, just do 'cp FILE ~/.kde/share/autostart && echo Hidden=true >> ~/.kde/share/autostart/FILE)

Currently my Kubuntu uses 222mb right after startup.

Also i'm investigating why the programs I really need (kmix, klipper, etc) are taking so much ram. first results showed that at least 4megs are used to store font data (allocated by qHBNewFace() call in src/gui/text/qfontengine_ft.cpp, and this is not shared across different processes!)

Please share any additional ideas on how to reduce memory footprint of KDE.

Lokalize in 4.8

What's new in Lokalize from KDE 4.8:

Translation memory based QA: you can have a permanent list of translator's false friends and check your TM (which can be made to reflect all your project) against them whenever you like. Because the check is done based on TM and not real files, this should work much faster [than pology]. And you can even add this list to your language dir in SVN repository to share it among other team members, the way it is done with glossaries.

Also:
* better support for real world glossaries, including large ones;
* improvements in XLIFF support (part of them contributed by Albert Astals Cid)
* faster UI
* some 14 bugfixes (apart from what was available in 4.7.x updates)

I'd like to say 'thank you' to all bug reporters. Apart from QA feature, all other changes were made as a reaction to user requests.

free software and outside world

i'd like to say a word on kde 'marketing' topic as well.

i think for free software developers marketing should really mean paying attention to bugzilla and fixing/implementing what users are asking.

this way users whose wish was fulfilled will readily spread the word about us.

i know few people who have ideas on how to improve the software they use (for example DJ software),
but chances that owners of non-free software will implement them are low. so the point is to show that it is worth filling the bug reports, i.e. that a user will be heard.

P.S. i closed 9 lokalize bugs in the last 2 weeks :)

creating passion, not creating product

this phrase have caught me in Dion Moult's blogpost "The kde-www war: part 4"

this is actually the main idea behind some scientific theory of society. 'economics should be transformed into pedagogics': people should learn how to make products like food, clothes, buildings, railways, electronic equipment, and the side effect of their learning would be real products.

but nowadays most of the people take part in activities focused on creating consumer products, and get [minimal needed] knowledge only as a side-effect.

the point in the pedagogics society is that when you have learned smth, and also tought it to others, you move on to another industry field. this way you never get bored, and you feel yourself a human, not a non-conscious machine that does same thing all the time.

Do you know about World Festival of Youth and Students?

This gathering can be of interest IMO for the free software community, as a self-organizing movement.

The gathering is a general one, has a long history and, I believe, can particularly touch intellectual property subject. It's happening on 13-21 of December. See Wikipedia article and offical site for the current 17th gathering.

On a side note, during the last weeks I returned to Lokalize development: fixed few bugs reported via bugs.kde.org, did few optimizations. I hope you'll like a more polished Lokalize in KDE 4.6 (sorry, the wishes that require new messages will have to wait until KDE 4.7...).
