I hit this problem when I was adding code to support storing encrypted passphrases in gnome-keyring for subversion. When we add a new key to the default keyring we are prompted for a password for locking/unlocking the default keyring. Sometimes I forget the password which I gave to this default keyring, which prevents me from viewing the default keyring and the keys associated with them, using the gnome-keyring-manager.

I found out that these encrypted passwords all those associated information about the keyrings are stored in the file '~/.gnome2/keyrings/default.keyring' in Debian based distros.

In Debian it is sometimes possible to have different alternatives for the same program. One such is 'java'. We have the GNU gcj and Sun provided java compilers available in Debian etch. I had the following java installed in my box as default
java version "1.4.2"
gij (GNU libgcj) version 4.1.2 20061115 (prerelease) (Debian 4.1.1-20)

I wanted to switch to Sun provided java version.

I have an external hard disk which is formatted in ntfs. I enabled ntfs-3g support in Debian etch box using some backport ntfs-3g deb files which was pretty old. Whenever I do a 'mount -t ntfs-3g blah blah' it gives a warning saying that ntfs partition is in use and try mounting with '-o force' option. I neglected the warning and mounted using force several times. Also used the hard disk in my ubuntu box where when I tried copying or rsyncing between folders at times it says some I/O error and failed copying/stating some files. It kept on increasing and lots of files in my hard disk got corrupted.

Today I loaded my laptop with Ubuntu 8.04 LTS version which comes along with Firefox version 3.0b5. As soon as I installed I tried hitting but I got an error which was like an error we used to see when the internet connection is not working. So I checked all my network connections my wireless connection but in vain. Tried rebooting which also did not help. After which I tried to read the error closely which said "Firefox is working in offline mode".

Then immediately I went to Edit -> Preferences and searched through the option to enable the online mode, but couldn't find one. At last after going through all the menu Items found the menu item to enable online mode here File -> Work Offline

'sloccount' is an excellent program to count the physical source lines of code (SLOC).

Available via 'sudo apt-get install sloccount' in all Debian based distros :)

Thanks to krish ( who gave me a hint on playing dos games inside a GNU/Linux box. Now am able to play Dangerous Dave in my Debian Etch box with the help of 'dosbox'.

I ve played this game in my 6th standard in the school computer labs. This was the first game which attracted me, and still today am very fond of this game. Some of the other games I would love to play are Prince of Persia, Pacman. But I don't want to use 'Doze' for playing these games. 'dosbox' is the best alternative, to play these games I guess.

See a screenshot in the attachment.
