Wired's Quinn Norton has a great feature in today about amateur clock-hackers who build their own super-accurate atomic clocks. These "Time Nuts" pull stunts like taking their kids hiking in the mountains for a couple days, using their cesium clocks to recreate Einstein's time-gravity experiment to prove that the family had gained 22 nanoseconds on their neighbors by rising high above Earth's gravatic center.
This is just part one -- more tomorrow!
With the end of the Cold War, and with telecommunications technology advancing rapidly, surplus stores and eBay have filled up with discarded precision time equipment once beyond the reach of all but governments. Cesium clocks, rubidium clocks and even the occasional hydrogen maser can be had for less than a decent laptop. A recent search on eBay turned up an HP 5061B cesium standard for sale for $2,000, and you can get a telecom surplus rubidium standard for less than $400. Some of this equipment costs upwards of $50,000 new.
Their access to once-forbidden technology lets the time hackers play in a realm of precision that underpins the modern technological world. A select few, like Van Baak, have started exploring the underpinnings of the universe.

Samsung claims to have developed an “Ultra Thin Glass” for its new Galaxy Z Flip foldable smartphone, signalling scratch resistance and durability beyond that of similar products. But tests conducted by Zack Nelson using a Mohs Hardness Testkit [Amazon] — a set of styluses made of different materials — show that it is no more […]
There is very little evidence that Ring reduces crime. Hundreds of police departments have signed agreements with Amazon-owned Ring to obtain access to the home surveillance camera footage. Interviews with many of them, in 8 different states, show little to no evidence that Ring actually deters criminal activity.
If you remember your Norse mythology (or just watched Marvel’s Thor movies), you’re probably familiar with Heimdal, the god whose ever-watchful eye was entrusted with protecting the home of the gods in Asgard. Back on Earth, Heimdal Thor is also the name of a security package from Heimdal Security, that’s actually dedicated to much the […]
Everyone’s got their nose in a phone these days, and that doesn’t seem like it’s going to change anytime soon. With the increase in mobile device and e-commerce reliance comes increased need for developers who can build the apps we’re all so glued to. In fact, employment of devs is expected to grow up to […]
