If you enjoy downloading files from those useful but not always so user friendly online dump sites like megaupload.com, rapidshare.com or mediafire.com to name a few (be it as a premium OR free member), then taking a look at the clever file downloader named JDownloader might well be worth your while.
JDownloader is an open source, platform independent file download manager written in Java. It’s particular strength lies in downloading files from so-called one-click-hosters and as such handles all the annoying little things like automatic link decryption, as well as offering multiple parallel stream downloading, captcha recognition and automatic file extraction. It can import CCF, RSDF and DLC files, and in general is just a pretty useful file download manager to have running on your system.
To get it installed on your Ubuntu 10.0.4 Lucid Lynx installation is as easy as running the following from a terminal console:
sudo add-apt-repository ppa:jd-team/jdownloader
sudo apt-get update
sudo apt-get install jdownloader
Nifty.
