GreenSQL – Defensor of the charts
Posted on 18 December 2009 | No responses
GreenSQL is free software and is used to prevent successful attacks on SQL databases. GreenSQL is a firewall for database server and is interacting like a proxy between the applications which need the databases and the DB server itself. It analyses SQL commands and has two modes:
- Simulation – Reports suspicious queries to the administrator
- Blocking – Blocks suspicious queries by itself
The software is endowed with a mode, that allows it to “learn” to distinguish between safe and unsafe queries. This is managed by Whitelists. So the administrator should always be very carefully when checking the this list.

Blogging live from Copenhagen
Posted on 13 December 2009 | No responses
Hi there 
As you may know: we are blogging live in Luxemburgish language from the UN Climate Conference in Copenhagen on Sokrates.lu It’s a look worth! That’s also the reason why I’m not blogging about the entire UNCCC here.

A story that isn’t hardly to believe, but very hardly to understand
Posted on 13 December 2009 | No responses
A summary of the story can be found here. Now my point of view: it’s not difficult to know that I disagree completely with the authorities. In a political state with democratic values and laws it shouldn’t be possible to have the rights as authorities to operate the way they did. They ran in the door, confiscated some technical gear and accused innocent people of trying to commit a crime against… Yeah, against what? The human feature of being curious? Or the fact trying to understand and improving technologies? These arguments don’t sound reasonable to me. I’ll hope that the “everyone who is able to handle technology correctly and beyond the given borders (specifically computer science) is a potential criminal” cliché will come soon to its end.

Server Crash / Linux-Magazine: Special issue about the Kernel of GNU/Linux
Posted on 6 December 2009 | No responses
Hi
I’m sorry for the elusiveness of the blog and the server. Now all is running fine again. One blog post has been deleted and can’t be recovered. It was a small one about the heart of GNU/Linux – the kernel. I mentioned that a special issue of the Linux-Magazine has been published about the topic (211 pages). The book/magazine is in German language and can be bought here (also more information).
Greetings,

Thoughts: 2 more or less complex questions
Posted on 25 November 2009 | 1 response
- Would we care more about our world, thus mother nature and the entire humanity, if we would know that we won’t die?!
- We know that our brain is able to send and receive electromagnetic frequencies, so why wouldn’t déjà vu’s be parts of other lives from alternative realities?
Feel free to share your thoughts and results. I’ll do the same in a few days from today.
Greetings,

Stargate Universe – Thorough Success
Posted on 25 October 2009 | No responses
I would be lying if I’d say that I doubted just for even one second on Stargate Universe. I’m happy that I didn’t. Oh this derivate of Stargate SG-1 and Atlantis is breathtaking great. Can’t await to see more and more and more. I’m absolutely devouring one episode after another. But now I have t wait til next Friday the 30th. You can watch all episodes on SyFy and on YouTube (HD Quality, don’t forget to hit the button;)). More soon.
Official first Stargate Universe Trailer
With friendly regards,
Prometheus
P.S.: As a Stargate fan since the first episode of SG-1 til now and forever I have to admit that me too I hoped that O’Neill and Carter would finally end up together in a relationship, but officially it never came to this fact. Now after 4 episodes of SGU (soon 5 episodes – I still have to wait a few minutes til the video is completely loaded) I have to say, that I really hope that Eli (“the computer hacking dropout” xD )will manage it to establish a connection through the “relationship API” to Chloe. 
Update
Stargate Universe Water – Trailer (first run on October the 30th on SyFy)
This woman knows what she’s talking about
Posted on 15 October 2009 | 3 responses
Just a short anecdote:
She was the Federal Minister of Justice in Germany. That means, she played a very important role in investigations which are related to “computer crimes”, surveillance and stuff like this.
But as every one can clearly see: she’s very qualified for this position and above all she knows exactly what she’s talking about.
Cheers,

NVidia 185 driver couldn’t be activated (Ubuntu – Karmic Koala)
Posted on 15 October 2009 | No responses
After I installed the graphic drivers I've done a reboot and ended up with a blank screen (black). Booting from a Live CD and editing the /etc/X11/xorg.conf file was the fastest way the fix this.
You have to alter the Driver entry of line 12 from nvidia to nv. Save and reboot.Section "Screen" Identifier "Default Screen" DefaultDepth 24 EndSection Section "Module" Load "glx" EndSection Section "Device" Identifier "Default Device" Driver "nvidia" Option "NoLogo" "True" EndSectionAfter this I was back Online and I've executed this command:
sudo dpkg-reconfigure nvidia-185-kernel-sourceIt [dpkg-reconfigure] reconfigures packages after they've already been configured and installed.
Reboot and afterwards it should work properly.More information:
[1] Google Results on: activate nvidia 185 driver ubuntu
[2] Ubuntu Launchpad - jockey does not correctly install nvidia 185 driver
[3] Ubuntu Launchpad - xorg: failed to load module "nvidia"

Upgraded to Ubuntu 9.10 – Karmic Kola
Posted on 7 October 2009 | No responses
Since a few days now I’m running the new version of Ubuntu on my machine and I’m very satisfied about it – again. It’s running properly except for the one or two things. For example:
Installing some deb packages by a simple double click is causing me problems. The error message which I always get is the following one:
unable to read filedescriptor flags for <package status and progress file descriptor>: Bad file descriptor
The solution wasn’t very difficult to find. ^^ Type:
sudo dpkg -i foobar.deb
foobar stands for the name of the Debian package. Don’t forget to change to the correct directory.
Another annoying bug is, that I have tried 3 methods to make the shortcut CTRL + F1 available to start a GNOME Terminal, but without success. As soon as I will have the solution, I post it.
Update: After a fourth try it worked. Open the gconf-editor and go to apps –> metacity. Now go to global_keybindings and choose a run_command_x. After you’ve stored the shortcut go to keybinding_commands and enter the exact terminal command in the box of the command_x. Close the app and have fun.
For the rest the system is running fine. The startup itself has increased about 4 or 5 seconds in contrast with 9.04. And the ext4 filesystem is doing a great job as well. The performance increase is notable.
More information are available behind this link.
So stay tuned.
