Tutorial quote: If like me, you do most of your work from the command-line, using vim to edit files, mutt for e-mails, cd/ls/mv/find/etc instead of a file manager, then you may get annoyed by having to fire up a GUI calculator to make (what may sometimes be) a single calculation.

One useful feature of calculating on the command-line is that you can see what you've typed. For instance, sometimes when I'm entering a long, complex calculation on a calculator (either the GUI or the solid, hold-in-your-hand type), I sometimes forget if I've actually typed in all those numbers or made the calculations in the right order.

This should probably be the coolest command-line utility that I have seen in recent days. Byzanz records your desktop session to an animated GIF. You can record your entire screen, a single window, an arbitrary region or even follow the cursor. Given that it is only a GIF format makes it even more an interesting proposition as the file size is going to be very small.

Post date: April 13, 2005, 19:04 Category: System Views: 5674 Comments
Tutorial quote: My reasoning for combining the traditional Debian apt command with Mepis was speed and efficiency. Also, in the fine tradition of open source, I could choose to use the command line instead of the Kpackage or Mepis System Center package management screen. This is a good way to learn about Debian systems that builds confidence for new users right off the bat.

Let's see how apt works with Mepis.
