An easy to use Screen Capture Program for the Mac

Let’s keep it simple. Here is a sample screen.
Sample of Skitch screen capture

Skitch, a public beta release from the same company that produced Comic Life, is quick and easy to use.
Capture the screen immediately, use a countdown timer, or even use your webcam. Once the image is caught, you can draw or type on it, erase your mistakes, and quickly drag it into an email. It automatically saves your work & even has a history function.

Use Numbers and Letters only when naming a file, folder, drive, or computer

Nothing is so frustrating as having trouble installing a program that you have used for many years. It took four tries to get Kid Pix installed recently. The reason? The hard drive had a blank space and a / in its name. The program was looking for a subdirectory called “blank space.”

Some programs warn you about naming conventions. For example, the current version of Apple’s Print Center warns you that some printers have problems with spaces in print queue names. Most, however, do not.

When naming things on a computer:

  • Use a name that will help you to find it again
  • Keep the name as short as is comfortable for you. While your computer may allow very long file names, you will run into problems with communicating with another computer or sending a file in email. 36 numbers, letters, and spaces is about as long as you want to use.
  • Use numbers, letters, and underscores to name a file. Most modern computers do not have a problem with spaces in a name but that is not true of everything, including printers, scanners, external hard drives, etc.
  • Don’t use special characters such as ?, /.|,\, “, -, *. Yes, some computers do well with them. The problem occurs when communicating with another person, computer, or machine.

Follow these naming rules and you will have much less trouble with your computer.
