Resolving Ext3 Error: No journal on filesystem

Ext3 is a journaled file system and maintains a journal file to prevent instances of metadata corruption due to unexpected power outage. Due to its wide testing base and relative simplicity, the file system is considered to be safer than its counterparts. But it is not completely immune to crashes. At times, when using a Ext3 formatted drive, you might receive errors suggesting that system doesn't find any journal on the file system. As a solution, you might be compelled to reinstall the system. In such situations, you need to check the status of your backup that should be valid and completely updated to restore information from. But if you observe any backup related issues, Linux Recovery utilities should be used.

For an instance, while attempting to mount your Linux based hard drive, you might come across the similar error message:

“ext3: no journal on filesystem”

WineXS – Simple graphical environment to configure Wine

Wine is an Open Source implementation of the Windows API on top of X and Unix.Think of Wine as a compatibility layer for running Windows programs. Wine does not require Microsoft Windows, as it is a completely free alternative implementation of the Windows API consisting of 100% non-Microsoft code,
however Wine can optionally use native Windows DLLs if they are available. Wine provides both a development toolkit for porting Windows source code to Unix as well as a program loader, allowing many unmodified Windows programs to run on x86-based Unixes, including Linux, FreeBSD, and Solaris.

WineXS allows you to easily configure Wine by installing and removing software, editing the registry,managing files, and more.

Google Gears For 64bit Linux & Firefox

Google has a fantastic little add on called Gears, unfortunately there is no support from Google to install Google Gears on your 64bit Linux machine. However, the good news is that Google was kind enough to provide Gears as open source! Users of Gmail, Wordpress, Greasemonkey and Wikipedia can greatly benefit from this little gem. Gears is a extension that allows you to take commonly used web applications off line. Storing essential components locally on your computer, making them as quick as can be. More on Google Gears can be found here.

There have been a few different people to release a 64bit compatible Gears add on, however some have issues and some don't. So far, I've found the best one to be written by a nice guy who calls himself Niels. Niels of Niels` blog has a link here on his blog.

Back In Time – A Simple backup tool for ubuntu

Back In Time is a simple backup tool for Linux inspired from “flyback project” and “TimeVault”.The backup is done by taking snapshots of a specified set of directories.Keep in mind that Back In Time is just a GUI. The real magic is done by rsync (take snapshots and restore), diff (check if somethind changed) and cp (make hardlinks).

Back In Time acts as a “user mode” backup system. This means that you can backup/restore only folders you have write access to (actually you can backup read-only folders, but you can’t restore them).
