16- Ekiga: Skype is a must have for many people out there looking to video chat with their contacts. And why not? – there is a working Skype client for all three major platforms, including Linux. But with Skype now owned by Microsoft, it might be time to begin looking more closely at Ekiga as a viable alternative.
The single biggest buzz-kill I know of with Ekiga is the lack of real client support for OS X. Software listed as compliant with Ekiga is either dead in development or simply doesn't work all the way.
17- FreeMind: Windows users have found MindManager to be very effective in making sure that creative ideas are brought forth in a visual sort of way. And thanks to FreeMind for Linux users, this goal can be accomplished without the extra price tag or needing to be run a non-Linux operating system.
Like many advanced applications that are run on Linux these days, FreeMind is run with Java. To most people this is not a problem, but to others looking for mind mapping software, Java is a show stopper.
18- Filezilla: Running SmartFTP is common among the Web designers on the Windows platform, but cross-platform Filezilla does so much of the same thing that it almost seems silly to use anything else. I've actually found that Filezilla seems more reliable than the other FTP clients I’ve used on Windows.
Add to it that it looks the same on any platform, and my feelings aren't hurt at all. Some users will likely be able to help me out with this, but I haven't been able to find anything I dislike about Filezilla in its recent releases. It has everything I could want from a decent FTP client.
19- Empathy: Only a year or two ago the world was ablaze about Digsby being the greatest instant messenger client out there. Back on the Linux front, I've found that Empathy works just fine for my needs. Not only that, but I can keep my social network logins in a separate client called Gwibber instead of piling them all into one. For me, perhaps the biggest advantage to using Empathy over Digsby is being able to use video chat.
20- Gufw: Like Windows, both the Gnome and KDE desktops have a number of great tools to set up the best firewall settings the user could need. And while Windows users have the Windows built-in firewall, Linux distributions such as Ubuntu offer something called ufw. By itself, it's easy to use from a command line. However, I've found tossing in the Gufw front end can go a long way toward making firewall control even easier.
One of the ways around the issues of security and control that make some businesses wary of cloud computing is to build a private cloud -- one that remains within the corporate firewall and is wholly controlled internally. Private clouds also increase the agility of IT an organization's IT infrastructure and make it easier to roll out new technology projects.
