KDE4: Panel artifacts when using Thunderbird or OOo using NVIDIA drivers

NVIDIA has had the best drivers for Linux users for several years. Since early releases of KDE 4, however, some nasty artifacts appeared when running some Gnome based applications (like Open Office and Thunderbird) on systems with NVIDIA cards. These bugs have been reported to NVIDIA but haven't been addressed until now. According to this very long thread, the latest beta drivers from NVIDIA (180.x) the nasty artifacts should have disappeared. I compiled and installed this latest driver and indeed, the panel corruption when, for example, composing a new mail in Thunderbird does no longer appear. Finally, people running KDE 4 with NVIDIA cards are no longer nvidia-victims :)

Remove copy protection from PDF documents

This is probably illegal, so use it at your own risk. Some PDFs on the internet have a copy protection to make sure you cannot copy-paste any content from the PDF into a document you're writing. To circumvent this protection there are several tools available on the internet. I haven't tried any of them, because they're not free ;) There is however a procedure that will enable you to circumvent the copy protection using free tools. The trick is to convert the PDF to a PS (PostScript) document first and then convert it back into a PDF. So, download Ghostview en Ghostscript from: http://www.cs.wisc.edu/~ghost/ . Next, open your PDF in Ghostview. Next, from the "File" menu, select "Convert" (a dialog will pop up) Press "Ok" Fill in the name of the "converted" file. Press "Save" Tada, you can now copy content from your newly created PDF ;)

The story of the Cobalt Qube

Image
The other week, a friendly colleague of mine brought me a small present. He gave me one of his Cobalt Qube s (for free!) which was collecting dust at his home. He was certain that I could give it a better use. I think I can still remember the days these things hit the market (somewhere in the late 90's). This was a home / office server appliance way before the people of Microsoft thought up their Windows Home Server . It was running some modified version of Linux RedHat, featuring a web interface for all administrative tasks. It also had 2 network cards, so you could easily turn it into a gateway / firewall. The RedHat version running on the Qube was known to be notoriously insecure. It was also running an older 2.0.x kernel which was outdated, even at that time. The Qube 2700 and Qube 2 were both equipped with a MIPS processor. Later models had an i386 architecture. Mine was a Qube 2. Getting the serial connection to work The Qube does not have any VGA adapter, so if you want to s

Jori Hulkkonen feat. Jerry Valuri - Lo-Fiction

If someone would ask me to compile a list of 10 personal favorites, Lo-Fiction would definitely be ranked very high. I don't think anyone would disagree with this statement. P.S. If someone is able to find the lyrics for this song, please be so kind to post a link. Even though it's English I don't always understand what he's singing about :(
