Firefox Disables Microsoft .NET Addon

2010-05-27 1 min read Linux

Firefox Disables Microsoft .NET Addon ZosX writes ”Around 11:45 PM Friday night, I was prompted by Firefox that it had disabled the addons that Microsoft has been including with .NET — specifically, the .NET Framework Assistant and the Windows Presentation Foundation. The popup announcing this said that the ’following addons have been known to cause stability or security issues with Firefox.’ Thanks, Mozilla team, for hitting the kill switch and hopefully this will get Microsoft to release a patch sooner.” Here’s the Mozilla security blog entry announcing the block, which Mozilla implemented via its blocklisting mechanism.

2010-05-25 1 min read Fedora GNOME Linux

I had been using quite different set of tools to this but this is really good. Just install the gnome-disk-manager with

The interface is very clean and easy to understand and is it very very fast when compared to the other Graphical utilities.

Here are some screenshots to take you through.

The power of find command in Linux – advanced.

2010-05-24 2 min read Linux

Generally whoever uses Linux, would know about the find command. Find the man page <a href="http://amit.themafia.info/phpMan.php?parameter=find&mode=man" target="_blank">here.

There are also lots of blogs, tutorials and other articles on find command on the web, so why write another one. Because it’s worth every word spent on it 🙂
find is a very powerful command, let’s see how (options for find command from man page and usage):

–depth — Process each directory’s contents before the directory itself.
–maxdepth — Descend at most levels (a non-negative integer) levels of directories below the command line arguments.
–xdev — Don’t descend directories on other filesystems.
–executable — Matches files which are executable and directories which are searchable (in a file name resolution sense).
This takes into account access control lists and other permissions artefacts which the -perm test ignores.
–iname — Like -name, but the match is case insensitive.
–nogroup — No group corresponds to file’s numeric group ID.
–nouser — No user corresponds to file’s numeric user ID.
–fls file — True; like -ls but write to file like -fprint.
–ok command — Like -exec but ask the user first (on the standard input);
–print0 — True; print the full file name on the standard output, followed by a null character
(instead of the newline character that -print uses).
–printf format — True; print format on the standard output, interpreting ’’ escapes and ’%’ directives.
