U.S. Navy Starts Delivering Drones Using Balloons and Submarines
So that's one way of stealthily deploying a drone, but an even wilder way is by using a high-altitude weather balloon with a drone stapled to it, with drones stapled to it.
Nope, that's not a typo: The Naval Research Laboratory has been using weather balloons to carry a medium-sized Tempest UAV up to 60,000 feet, and the Tempest UAV itself is carrying a pair of tiny little CICADA (Close-In Covert Autonomous Disposable Aircraft ) drones underneath its wings.
Each CICADA can carry a variety of sensor payloads, and as the name implies, they're designed to be cheap and disposable: The airframe is actually just a custom printed circuit board.
This balloon launch multi-drone thing in particular is very cool, since whatever you attach to the balloon can use its engine purely for range as opposed to altitude.

A Web page that finds anagrams through an interactive procedure.
Of course, another anagram for it is “sotp”, but that is not a word, and we are mostly interested in anagrams that are real words.
The solution came out a few months later and I immediately applied it on the Unix machine I had at work.
It came up with all the anagrams that would fit a given set of words: this often ran to thousands or hundreds of thousands of anagrams, often pretty unintelligible.
I am using a “naïve” algorithm for word-fitting, but these days CPU cycles come much cheaper.
Most of the fun ones come from people’s names, but I will have to withhold them since my friends might not like to see their names and anagrams splashed all over the Web.
