There's An Actual Name And Reason For Those Beeps You Hear In Recordings Of Astronauts In Space via Gizmodo

An excellent article on all those beeps you heard during Apollo mission and what it all means. Best explanation I have seen and it all has to do with signaling and switching. — Douglas

The American space program, I think we’d all agree, has its own very particular set of audiovisual signatures that immediately evoke all kinds of images and feelings. There’s a certain NASA look to the objects of space travel—that gold foil stuff, lightweight aluminum frameworks, white panels with American flags on them—that is immediately recognizable. The same goes for the sounds of NASA, a certain type of distorted audio, and, perhaps most evocatively, those beeps you always hear in transmissions between astronauts and ground control. But what the hell are those beeps, anyway? What do they actually do? Relax. I’m going to tell you.

Add in more than one kid and organizing your life can quickly become a nightmare. This is exactly why one of my most important organizing devices is a shared calendar that reflects all the activities and events for everyone in the household...and I do mean everything. If someone -- is required to be somewhere -- at sometime, it goes into the calendar.

One feature I really like in Google Docs is the easy, online file sharing that also allows you to edit simultaneously with someone else.
