1. Steganography (cat, unzip)
Thanks to this post by ambition here, I learned something I really wanted to do: hide a file inside a picture. I knew this was possible, but I never managed to learn how to perform the feat in Windows.
I discovered that it is truly easy in Linux. All you need is the command cat to join the files and the command unzip to retrieve the hidden file.
To begin with, you must have an image file (I used *.jpg, *.jpeg, *.png and the three work nicely) and your secret archive as a zipped file.
You use the command:
cat name_of_pic.jpg name_of_secret_file.zip > new_image_name.jpg
That's it! The new picture containing the secret file is created.
It is amazing how easy this is in Linux.
The ASCII rendition looks great, doesn't it?
3. Browsing the Web (Lynx)
I'm taking my first steps here. It is good to be able to browse the Web from konsole.

With these tools, I practically can do all I need for a class if my GUI crashes... Of course, my poor Windows-only students might feel that the computer is possessed or something ;-)
