`ed' is a line-oriented text editor. It is used to create, display, modify and otherwise manipulate text files, both interactively and via shell scripts. A restricted version of `ed', `red', can only edit files in the current directory and cannot execute shell commands. `ed' is the `standard' text editor in the sense that it is the original editor for Unix, and thus widely available. For most purposes, however, it is superseded by full-screen editors such as Emacs.

A follow up to my original post comparing all 5 existing iPhone cameras. This time I'm challenging all 5 iPhone cameras in 3 common low-light conditions:

   An indoor market shot with low ambient light
   A food shot in a dimly lit restaurant
   A street shot at night

The back of the laptop has been, historically, bare and useless. Quickly turn this space into a portable whiteboard with custom cut DrawTop vinyl adhesives.

Get rid of backs of envelopes, lunch table napkins, and clumsy whiteboard apps -- design and collaborate in any meeting where you carry your laptop.

Use DrawTop to turn heads and attract attention to your message in coffee shops, conferences, and on the bus. Leave yourself notes, make a to-do list, send a message, post a sign, design a website, design the world -- get drawing!
