How to disable generating previews of media files in Nautilus (GNOME), Fedora 10.

It would be the easiest to have gconf-editor installed.

By default, when you have this app installed, you can find it here:

Applications > System Tools > Configuration Editor

Go to:

desktop/gnome/thumbnailers

There you can find every file type that has preview enabled. To disable all of them at once just check "disable_all" in the "thumbnailers" entry, or you can just find the media type you don't want to have preview generated (they are listed as a sub-directories of "thumbnailers") and uncheck "enable" key.

Howto - convert chm to html.

To do it, we'll need a tiny command line program - extract_chmLib, which is distributed with chmlib package almost in all distributions. However, if you're using Fedora 8 you probably need to download chmlib source code from here. The newest version available for me was 0.39. Extract it and compile:

./configure --enable-examples
make

Installation is not necessary. Extract_chmLib is hidden here:

src/.libs/extract_chmLib

To convert chm file to html, or rather extract html files from chm just type:

extract_chmLib file.chm output_directory/

What you end up with should be a website, which you can index using Beagle or Gnome Desktop. It saves a lot of time usually spend on digging through personal library.
Have a nice time compiling.

I've done it using Fedora 8, and needed only standard development packages.
