Auweia!

Bei einer mehrtägigen Cyberattacke auf das deutsche Parlament haben Hacker auch Daten abgezogen. Das hat die Bundestagsverwaltung jetzt bestätigt. Nicht bekannt ist, wer hinter dem Angriff steckt und ob er noch andauert.

The title slide says it all. FTW!
 
These are the slides of the presentation done by me on #DORSCLUC 2015 in Zagreb about how to setup and correctly integrate the Kolab groupware solution and Seafile filestorage/syncing. Also it goes over some considerations to take into account when setting up a service that you will trust your valuable data with, such as redundancy and failover facilities.
The PDF is also online so that you can copy/paste the commands and config files easier:

+Kolab.org Community 
Hosting your own servers for groupware and filestorage can be very compelling because of a number of reasons. But doing it right can be quite a tedious job. This workshop, which was given at the DORS/CLUC conference in Zagreb will guide you through installing the Kolab groupware solution and integrate the Seafile filesyncing application with it, creating your own personal data bank!

Great! I have not managed to install Kolab on Ubuntu yet... it runs great in CentOS, but now I will try it again on Ubuntu :-)

The first step in making the world you want is to behave in line with that vision. Mark apparently doesn't understand that, having spent the last years creating schism after schism in the Linux desktop world, from Mir to Unity to making their own QML API from scratch and developing a mobile UX behind closed doors separate from work being done in the broader community, he is now suggesting that all the desktop projects should work together towards a common goal.

You first, Mark. You've adopted systemd, and that's a nice step ... how about the rest of the separate silo Canonical stack? Example: Get behind Wayland and you'll have automatically given all the desktop projects a common goal, since the rest of them are already there just waiting for you.

To be honest, the way I read it, what Mark really wants is everyone to use and develop for what his team has dreamed up. That would also accomplish his proposal, I suppose. It would be just like when he was trying to convince every project to adopt not just a 6 month cycle but the same 6 month cycle that Ubuntu was championing. "You change to be just like me and then we'll get along amazingly well," is a common mantra for Mark.

Disappointment does not quite start to describe my feelings about this call to arms. It's the right message, but delivered by someone who does not follow it at all.

Oh yes. I feel terribly slighted by Canonical. Let's see... Ubuntu/Xubuntu installs easily; plays nicely with other distros on my drive; provides every codec under the sun; easily installs nVidia drivers; provides a massive selection of applications; provides automatic, scheduled updates; provides LTS, sets up my wireless card without struggle; and will allow me one day to run the same O/S accross all of my devices.  But, worst of all, my desktop is very stable and just works! :) And the ads in the dashboard, I leave them turned on just for the constant annoyance..

A great conference ... and so much sense to run the Kolab Summit and openSUSE conferences in tandem -> shared resources, opportunities for cross-over, bigger draw together ...

Unfortunately, I missed the group photo by a few minutes, as I was running around doing last-hour prep/coord for the Roundcube announcement

Video of the closing session where I played talk-show-host and Thomas gave an excellent presentation about Roundcube ... and we announced Roundcube Next and its crowdfnding campaign.
 
If you weren't there for the live stream of the announcement of Roundcube Next at the Kolab Summit, you can catch it at the link below. Thomas gives a great review of Roundcube's past, present and future .. a moment of Roundcube history-in-the-making.

B-trees. How much is there to say about them, right? Well, lots :)

+Aaron Seigo I'm not sure why you explicit point out that reader and writers are in different processes. After all, any other situation wouldn't need further thinkind, would it?

And when I said "usually" I ment that I can't think of any.

I can't realy see any additional race conditions beyond the obvious. And especially how a notify about area intersect can cause a race at all.

I think at this point we would need at least a few beer to draw up some schemes to understand each others view of notification and race window.

Beside the data base part, the application logic also adds here.  I would never dare to go ahead in a writer task and collect input for  commiting a huge batch. Submiting each mail seperate to the database (within the update process) will cause way less potential issues.

Again, it comes down to the relation between reads and writes and how often they potentially intersect.

Be like Hans: Contact your hosting provider if they use Roundcube! 
 
The crowdfunding campaign to support Roundcube Next is making very good progress, already 30% of the initial target is funded! I've just emailed my hosting provider Telfort (which is a long time Roundcube user) to suggest them that they also join in and make sure they get a seat in the advisory board, will you do the same with your ISP?
Creating the future of email, together! | Crowdfunding is a democratic way to support the fundraising needs of your community. Make a contribution today!

I don't understand why this doesn't have more funding by now :( especially considering the way the whole private cloud thing is going :/

A nice "take the pulse" of Kolab courtesy of Swapnil..
 
What's next for Kolab, the privacy-minded open source unified communication and collaboration system that you can install on your own server.

What is the best feature of free software? e.g. if I asked you what the best feature of Linux was, what would you say?

Here are my thoughts on that, as delivered at the openSUSE conference last week at Den Haag.

This reminds me I should be using Diaspora instead of google plus.  Replacing youtube would be nice...

Another loooooong day at work ... the crowdfunding campaign is certainly not the only thing I'm working on today, but it is taking a good amount of energy. That said, we're in the top 5 trending technology projects on Indiegogo (and 22 over-all last I looked ...), and charting a nice climb with 132 backers in the first 3 days so far ... We can do it!
