(laughter) back in the day? what does it mean to be the co-father of the internet? >> bob conn and i, the other father of the internet, sat down in 1973 and began designing what is now the internet. the original project was done to help the defense project use computers in command and control. a computer can help you manage resources better which might mean the smaller force could overcome a larger one if the smaller one could manage its resources better than the opponent. >> stephen: did you build the switch where the computer turns on and kills all of humanity?

we'll limit them to the last six hours and now we have a large branches down near the intersection of vint road. that's around manassas and this is brand-new at 5:50, north of annapolis. pretty good size 5-inch cherry tree branch has been snapped off. sot storms, as we mentioned, the main threat wind damage. severe thunderstorm watch until 8:00. there's your wind damage threat. storms for the evening commute will continue on and off. if you're heading west on 66, you have a window of some dry weather. critical time between now and 9:00. here's your future cast. 7:30 -- especially up toward gaithersburg and the frederic area. i think they are under done in terms of intensity. now the computer by 10:00 adding some yellow, from leesburg to gaithersburg. going to walk the dog late, probably don't have much success north of town. a better chance down toward la plata and southern maryland. so we have 70s to start tomorrow. not quite as severe as it looks. shower and storms are possible. primarily once again afternoon and evening hours. yellow alert tomorrow, more storms, ask nice. 83, less humid
