Germany’s WARR team wins SpaceX’s Hyperloop II race with 201-mph pod run

The speediest team from SpaceX founder Elon Musk’s first Hyperloop pod competition has done it again: WARR Hyperloop from Germany’s Technical University of Munich won today’s second contest by sending its magnetic-levitation pod through a nearly mile-long test tunnel at a peak speed of 201 mph.

How the NSA identified Satoshi Nakamoto – Alexander Muse – Medium

Various reporters and members of the Bitcoin community have used various open source stylometry tools to attempt to uncover the true identity of Bitcoin’s creator. Their problem? They didn’t have access to trillions of emails from a billion people and they weren’t able to plug them into a supercomputer. The NSA’s proprietary software, bulk email collection ability, and computing power made it possible for them to conclusively identify Satoshi.


It does this by firing up JStylo libraries (an author detection application also develped by PSAL) to detect stylometric patterns and determine features (like word length, bigrams, trigrams, etc.) that the user should remove/add to help obsure their style and identity.

Mini-antennas could power brain-computer interfaces, medical devices

Engineers have figured out how to make antennas for wireless communication 100 times smaller than their current size, an advance that could lead to tiny brain implants, micro–medical devices, or phones you can wear on your finger. The brain implants in particular are “like science fiction,” says study author Nian Sun, an electrical engineer and materials scientist at Northeastern University in Boston. But that hasn’t stopped him from trying to make them a reality.

This ancient Babylonian tablet may contain the first evidence of trigonometry

Trigonometry, the study of the lengths and angles of triangles, sends most modern high schoolers scurrying to their cellphones to look up angles, sines, and cosines. Now, a fresh look at a 3700-year-old clay tablet suggests that Babylonian mathematicians not only developed the first trig table, beating the Greeks to the punch by more than 1000 years, but that they also figured out an entirely new way to look at the subject. However, other experts on the clay tablet, known as Plimpton 322 (P322), say the new work is speculative at best.

The Babylonians discovered a strange form of trigonometry

The Middle Eastern civilization created a trig table 1,000 years before the Greeks.

This Autonomous Forklift Wants to Eat Up Warehouse Jobs

It may look much like a regular pallet truck, but this is one of a growing number of autonomous warehouse vehicles looking to take over from inefficient humans.
