Repel Flies with a Bag of Water - Lifehacker

Houseflies, being highly edible and defenseless, are nervous types, and don't like to sit still when they see something moving nearby, because it could be a predator. The water bag acts a bit like a lens—try it some time—in which the movements of people in the area are reflected. Even if the fly is too far from the action to see it directly, it can see a shifting of light and dark in the water bag, which it interprets as nearby movement, and it will fly away from the bag.

Given that as a nation we are both accustomed to and annoyed by the pesky blowie I'm surprised that I had to read this on a US web site. Does it work?

iPhone battery life

Found this on the Apple site:

iPhone 3GS offers up to 5 hours of talk time on 3G, 12 hours of talk time on 2G, 5 hours of Internet use on 3G, 9 hours of Internet use on Wi-Fi, 10 hours of video playback, or 30 hours of audio playback on a full charge at original capacity. In addition, iPhone features up to 300 hours of standby time.

The page also has a heap of tips to prolong battery life and lifespan (two different things), most of which involve turning off everything that's useful on the phone, but I get the point. One tip that stood out: fully drain and recharge your iPhone at least once a month. I'm pretty sure you should do that with laptops and iPods too.
