Colin sez, "40-year-old Mikhail Puchkov decided to design and build a personal submarine during the stifling era of Leonid Brezhnev's regime when he was barely twenty years old. He built it secretly in an attic in Ryazan, about 120 miles southeast of Moscow."
Smallest Russian Submarine: Officially Registered as Boat
“I was not satisfied with the fate that was laid out for me. I wanted to satisfy myself and to have some respect for my life. If I learned to respect myself, I felt it would be easier to find my niche in life. I didn't know it would work. I just hoped.”
His family, particularly his father, condemned him and his submarine flights of fancy, and the longer the construction took, the more he complained. The first test of the sub came in 1984 and it “sank like a stone,” in Puchkov’s own words, breaking a rudder in the process and setting a climate for the early dives, which were always a bit tense. He said of those times:
“I was so distracted watching for leaks and checking all the equipment, that I didn't have time to enjoy it. You don't remember a thing afterward.”
It took three years before he was able to get the submarine to dive and surface. In 1988, he put the reinforced plastic sub in a box on a truck and shipped it to the Tosna River about 15 miles south of St. Petersburg. There, he continued his nocturnal voyages and in 1994, he took to the open sea on a secret cruise to the island of Kronshtadt, a closed military base in the Gulf of Finland.
Zero-knowledge proofs are one of the most important concepts in cryptography: they’re a way to “validate a computation on private data by allowing a prover to generate a cryptographic proof that asserts to the correctness of the computed output” — in other words, a way to prove that something is true without learning the details.
Retroworks’ $18 decoder rings don’t have much by way of cryptographic robustness (they compare disfavorably to the cipher-wheel wedding rings my wife and I wear!), but they’re not a bad way to introduce the littlies in your life to the idea of habitual secrecy. (via Red Ferret)
This week (and next due to the nature of different release dates for the direct market and the book market) marks the release of the first collection of SHADE THE CHANGING GIRL v.1: Earth Girl Made Easy, which compiles issues 1-6 (previously). It’s a heavy load to recreate a character that giants before you have written. Steve Ditko is a master of the strange. His mind a merry-go-round of experimentation.

Although fully autonomous vehicles aren’t yet allowed on public streets, they are poised to dominate the roads in the not-too-distant future. But before that happens, Apple, Google, Uber, and other companies now investing in self-driving tech are going to need talented developers that can account for the dizzying array of factors at play when a […]
