OFS proposal for Linux-Kongress accepted
Thursday July 1st, 2010 05:16 pm (UTC)
I’m very happy to inform you, that I will speak at this year’s Linux-Kongress.
Some weeks ago I submitted an abstract for a talk about OFS. This week an e-mail from the chair of the program committee arrived, telling me that the proposal had been accepted.
Together with Prof. Trommler and Samuel Walz, student from the last OFS project group, I will prepare the paper as well as the presentation.
The Linux-Kongress will take place at the Georg-Simon-Ohm University – the home of OFS. You will find more information such as programm and abstracts on their website http://www.linux-kongress.org/
Our talk is scheduled for 1:30 pm on the second day of talks and here is the link to the abstract.
Now there’s much work ahead, but I’m looking forward to this event.

Typo3 – my recommendation
Friday June 4th, 2010 03:46 pm (UTC)
Typo3 Backend
A few weeks ago I finished my first website based on the Typo3 CMS. The page of CJB (Christian Youth-alliance in Bavaria), which I took over webmaster position several years ago needed a complete redesign and in conjunction with this I decided to apply a content management system.
I’ve taken some time zu evaluate some others like Joomla!, CMS Made Simple and Redaxo but eventually got stuck with Typo3. I must admit it’s not that fast to learn but once you got the overall concept (and this is enough) you have a very powerfull system.
The software design of Typo3 is one of the clearest I’ve ever seen. Everything seems monolithic to me and it’s extremely easy to make it doing what you want. read on »

OFS linux magazine articles online
Tuesday December 22nd, 2009 01:08 am (UTC)
Article in english Linux Magazine
As you probably know we wrote an article about OFS for the german Linux Magazin and the english Linux Pro Magazine one year ago.
Both, the german and the english article are now available online.
English: http://www.linuxpromagazine.com/Issues/2009/99/CONNECTIONS/
German: http://www.linux-magazin.de/Heft-Abo/Ausgaben/2009/01/Verbindungssuche
I really recommend reading it if you did not had the possibility to get the magazine.
We wrote about the concepts of OFS and our plans. We went a big step into the right direction, but there is still much work. For example OFS is much more stable today, but we still lack a decent GUI.
Take a look at the articles and share our ideas.

DLNA – Easy home entertainment
Saturday December 12th, 2009 10:32 pm (UTC)
My father recently bought a new TV from sony which, beside other cool features, has support for DLNA.
DLNA (Digital Living Network Alliance) is a standard for networking entertainment devices such as TVs. One simple use-case is to have a server containing media files such as pictures, videos or movies. On the other hand you have your TV, Playstation or simply DLNA-able PC client as a viewer. The Client enables you to browse your files and demand the server to stream selected files.
Being a tech-interested person I tried to turn my linux server to a DLNA server. I discovered a very powerful daemon called minidlna. This was probably the easiest server I ever set up. Just copied the configuration file template to /etc, adjusted the directories my mediafiles are located and listed the network devices for communication.
Everything worked out of the box. After starting the server it scanned my configured directories for media files and announced itself via UPnP. I instantly was able to browse my media files from the TV, watch pictures and videos and listen to music.
Summary:
A very nice toy.
I have seen few software working such smooth, easy to set up and use.
You don’t need to pull out your notebook, boot it up, connect to the TV, log in, operate the PC, … – Just sit back into your couch take the remote control and browse through your files.
If you regularly show pictures of your last holyday to friends and relatives or watch movies located on your harddisc I recommend having a look at the DLNA concept.

OFS and csync
Wednesday July 1st, 2009 10:15 pm (UTC)
Today I met Andreas Schneider, developer of the csync tool. This little program is designed to effectively synchronize files between a local directory and a smb share without mounting it. It is especially used for implementing roaming profiles in linux.
Andreas is also very interested in file synchronization and offline working concepts. We shared some ideas and discussed the aims of our projects.
He has many innovative approaches to file synchronization in general and I see many points for collaboration.

Extended Attributes as user interface – be careful
Monday June 29th, 2009 10:54 pm (UTC)
We have decided to use extended attributes in OFS to enable communication between user and filesystem with standard linux tool. Today I came across the first disadvantage of this choice.
I was wondering why gedit claimed that it were not possible to save the backup file. After some debugging I discovered that it tried to copy all extended attributes from the original to the backup file.
In fact, this is a very good idea, especially when using ACLs (which are stored as extended attributes). In OFS we have a little problem with that. Think of setting the “ofs.available” flag to a random file inside the tree. This makes no sense is is denied by OFS. As a result, gedit failes in creating this file.
My fix for this was to hide the ofs.* attributes. This means I removed them from the listxattr FUSE callback, so that they are still available but get not exposed when someone asks for all available attributes.
I don’t know if using attributes which are not visible will raise new problems – time will show…

Student project: Cache-manager for OFS
Thursday June 18th, 2009 07:17 pm (UTC)
Today I visited university again. Three students held a presentation about caching strategies for OFS.
In March Professor Trommler started this project and the students did very good research since then. The approaches are promising and partially close to my own ideas about improvements in OFS.
I’m very keen on the implementation which will start about end of July, after they have finished their exams.
