Dan Kaminsky, the Jedi master of packet-level hacking, has figured out how to tunnel ssh over DNS, a stupendously weird and cool feat.

Simple maybe, but I didn’t […]

All the filters in the world won’t save your smartphone pics from a shaky hand. To really step up your mobile photography game, you’ll need some kind of mount to hold it steady.

The forced transition from analog to digital TV signals was probably met with relative indifference from people with Netflix subscriptions and the “I don’t even own a TV” snoots. But anyone living in the vast swaths of the country that don’t have guaranteed high-speed internet, broadcast TV is a perfectly valid (and 100% free) way […]
