Dropbox Uploader is a bash script you can use to access your Dropbox files from the command line, without having to install the Dropbox client. The script can upload, download, delete, share or list the files available in your Dropbox account. The script is useful in many situations, including: automatic backups, access Dropbox from an ARM server / Raspberry Pi , etc. (since Dropbox isn't available for ARM). That's because its only requirement is cURL, so you don't have to install the Dropbox client to quickly upload or download some files from Dropbox.

Customizing your xterm
Posted by Steve on Thu 30 Dec 2004 at 18:29 xterm is the default terminal emulator, or shell program, that people use when running the X11 Window System. Despite its apparent simplicity it's very customizable, allowing you to change fonts, sizes, and colours with only a little effort. Many newcomers to Linux don't realise that there are menu options available with xterms and instead seem to believe that they must use the KDE, or GNOME terminal applications to get adjust fonts.

Running Multiple Versions of Firefox in Ubuntu 9.10 - odyniec.net
Here’s a simple howto on running several different versions of Firefox in Ubuntu 9.10. This is the setup that I use to test my jQuery plugins and other JavaScript code — I hope some of you fellow developers out there will find it useful too. The basic advantage of this solution is that is does not clutter your basic system with unnecessary software packages, as all the additional files are stored in your home directory and nowhere else. I’m going to create a directory where all the different Firefox versions will reside. I have a dedicated directory for any software that I can’t or don’t want to install the standard way (using apt ), and it is located in my home directory – /home/michal/opt .How to Install multiple versions of Firefox on Ubuntu: 5 steps

It is easy enough but there are some little tricks to apply.
