This is how bad my internet connection has been for the last few days. For those of you who don't understand what that stuff means, each row contains 3 attempts to contact each router along the way from my apartment to www.google.com. Each asterisk is lost data, each number is successfully sent data (how many milliseconds it took for the answer to come back). We've had such ridiculously high packet loss that either the connection is totally gone or it's in a minimally functional state like this for the vast majority of the time.

Straight out of science fiction, IBM filed a patent on body armor that will use electrical impulses to make a person get out of the way of bullets. It's a pretty crazy idea, but wow. It's hard for us to really understand how slow bullets are since they are typically used at fairly short range. The example of a 2.5 km shot taking 4 seconds to reach its target definitely shows that this could be possible if the armor could detect a tiny projectile at a long enough range.

Harpooned is a game about killing whales for scientific research.... It's great to see that video games are being used to deliver more meaningful messages than mindless entertainment.
