Archaeologists Meaghan Dyer and Linda Fibiger from the University of Edinburgh ran an experiment to determine if the “Thames Beater,” found near the Thames river and radiocarbon-dated to about 4,600 years old, could inflict injuries matching those of damaged skulls found at Asparn/Schletz, a Neolithic massacre site in Austria. The injuries were nearly identical.
In a sort of quiet protest to the FCC net neutrality repeal, I finally got around to signing up with a VPN provider.

> Currently 12.5 bitcoins is more than $200,000, so naturally lots of people would like to add the next block to the blockchain. To win the right to add the next block, bitcoin miners compete against each other by performing a highly repetitive computation. They add a random value called a nonce to the candidate block they have assembled. Then they apply the SHA-256 hash function, which produces a short, seemingly random string of 1s and 0s that serves as a cryptographic fingerprint for the block. The goal is to find a block whose hash is very small—that is, its binary value starts with a large number of zeroes. As I'm writing this, a winning block needs a SHA-256 hash that starts with at least 72 zeros. Because SHA-256 hash values are essentially random, the only way to find a very low value is by repeated guessing. Most of the time, the hash value will be too high and the miner will repeat the process—changing the nonce and computing another hash value. Right now, the network computes around 7 x 10^21 SHA-256 hashes, on average, for every block that is created.
Jesus.
