Light and Fast Download Accelerator for Linux: Some of you may have used a download accelerator through a browser add-on but are not contented with the download speed gain. Perhaps you should try a light and fast standalone and desktop-based download manager that could help give considerable increase in download speed.Let me introduce you to Axel.

Google has recently released their very own DNS resolver with main goals of making web browsing faster and safer... replacing your ISP's slow DNS server with a third party DNS resolution service will help speed up your Internet connection. So if you are already using OpenDNS right now and are pleased with it, why not try Google Public DNS.

Google isn't content with providing us with fast search and a fast browser: we need a faster protocol between servers and browsers. The search giant would like us to start forgetting about HTTP:// and learn to love SPDY://.

Apt-Fast is a script which uses Axel, a command line application which accelerates HTTP/FTP downloads by using multiple sources for one file, and one can use it instead of "apt-get" on Debian based Linux distributions to get an amazing download speed improvement.

LuckyBackup is a backup and sync application running on Linux and Mac OSX, powered by the rsync tool.

It is simple to use, fast (transfers over only changes made and not all data), safe (keeps your data safe by checking all declared directories before proceeding in any data manipulation ), reliable and fully customizable.

What does it mean for a browser to be fast? It turns out to be a bit hard to pin down, really. I was asked about this and tried to give a lightning talk at the recent Ubuntu Developer Summit on how we think about application speed in general but I think I didn't make my points well, so I thought I'd try to expand a bit here on what you ought to consider when comparing browsers.

The past couple days I've been interested in the fastest gtk-engine-theme available to load on my Ubuntu box. I just simply didn't want fast but as elegant as I could get. My search did not have to go far after discovering a couple articles and speed tests that still had BlueCurve theme engine as the fastest and by far the most elegant considering the speed increase.

Ubuntu gets a new, fast desktop interface. For some time now Ubuntu chief Mark Shuttleworth has been pushing developers to speed up boot times in the Linux operating system. Now he has revealed Unity, a new interface that is aimed at netbooks users. He's also announced Ubuntu Light, a fast, light, version of Ubuntu that will offer almost instant-on boot times

I must say that I think Opera is doing a great job supporting its browser on Linux. Even though it's closed-source, it's still one of the most powerful web browsers out there, and each release comes with packages for every major distribution out there.
