This week we cover time and space, two small concepts that will help you travel back to 1956, or around the world in 24 hours. Then we try to expand on what TCP really stands for (and have to flee the country).
Fun Way to Send Attachments in Mail
If you're working in a file that you want to attach to a message in Apple Mail, you can transfer the file to Mail easily: From the title bar of the file's window, drag the little proxy icon to Mail's icon on the Dock. Your Mac will make Mail the active application and open a new outgoing message, with the file attached.
(If your icon won't drag, the file probably isn't saved.)
