During my Distro hopping days, I have tried and tested different flavors of Linux. There are several distros that I have considered forgettable, while there are others that have left a lasting impression on me simply because they have far exceeded my expectations.

gnoMint is a desktop application that lets you easily manage your own certificate authority (CA). Many secure communications technologies use digital certificates to ensure that the party or service they are connecting with is not an impostor.

When I typed on Google “Do I really need a firewall?” 695,000 results came across. And I'm pretty sure they must be saying “Hell yeah!”. In my opinion, no one would ever recommend anyone to sit naked on the internet keeping in mind the insecurity internet carries these days, unless you really know what you are doing.

A mail transport agent (MTA) provides the 'plumbing' for your email system by taking mail from a client application such as Evolution or Mozilla Thunderbird and routing it to the correct location on the right machine.

At first sight, the Read It Later (RIL) extension looks redundant -- after all, you can use Firefox's own bookmarking functionality to save Web pages for later reading. But dig deeper, and you'll discover that it offers enough nifty features to make it a must-have tool for most users.

Under Linux, installing new applications isn't a particularly hard task, but installations do come in several different varieties, so it's worth understanding the differences and what you'll need to know to make them work.

The Apache Web server is arguably the best and most powerful Web server software available for any operating system. While many learn to edit the configuration files and configure or enable various modules, the bulk of what most people do with Apache is manage the content that Apache serves, with very little attention paid to what Apache itself can do.

I applaud Canonical for pushing Ubuntu beyond the desktop — up onto servers, and down onto mobile devices. But I’m starting to wonder: Can Ubuntu really gain traction on Mobile Internet Devices (MIDs)? Or put more bluntly: Does the world really need another mobile device operating system?
