GLOBUS - The Soviet Mechanical "SPACE GPS" Before digital computers took over, Soviet spacecraft used something extraordinary: a fully mechanical navigation computer called Globus. Installed in missions like Vostok and Soyuz, this device used a system of gears, cams, and rotating mechanisms to calculate the spacecraft's position in real...

From Dan Lorenc on the malware attack that almost took down the entire internet last year: โ€œThereโ€™s a popular compression library thatโ€™s used in almost every piece of software. And it had been maintained by one person in his spare time for the last 20 years. And then a couple years ago, somebody just decided to start helping him. They jumped in, fixed a bunch of bugs, and did a lot of great work. And then that first person got tired of working on it. So he handed the whole project over to this other person. It turned out that other person was just a pseudonym and was not a real person. And within six months of getting control of the project, they had put in a carefully orchestrated set of malware that was really hard to detect and no one noticed. And because it was so widely used, the exploit would've basically given that person remote access to any computer running that piece of software, which was basically everything connected to the Internet. But because it was open source and the code was transparent, some random engineer just happened to be running some benchmarks on a weekend. And he noticed that program was a little bit slower than it used to be, and that it was making a weird cryptographic operation to check something. And right before this thing got widely deployed across every device, he dug in, and discovered that there was a backdoor put in. This was the closest thing to a full-blown internet crisis that weโ€™ve ever had. And they still have no idea who did it. It was just an anonymous email account. No one ever traced it back to an individual. And that's the long game. This person spent years just doing good work and earning the communities trust.โ€

BOOM! I have been donated a massive trove of former Soviet Union science and technology media for AI review and training (with caveats). I have the next big trove today. From films, video tape, pictures, microfilm and digital files. Millions of sources. No AI company has had this type of access to this type of data and I worked decades to make it happen. What are we seeing here? At 7:00 p.m. Moscow time, Mikhail Gorbachev delivered a live televised resignation speech in which he announced the end of his role as President of the Soviet Union, declaring that the office itself would cease to exist. Shortly after the address, the Soviet flag was lowered above the Moscow Kremlin and replaced with the Russian tricolour, a moment that became one of the defining images of the collapse of the USSR. The following day, on December 26 1991, the final regular broadcast of USSR Central Television signed off as the Soviet Union was formally dissolved by the Supreme Soviet. The closing moments included the playing of the Soviet national anthem for the final time before broadcasting transitioned to the new Russian television system. The televised resignation, the lowering of the flag, and the final Soviet broadcast together marked the symbolic and official end. The wall blocking closed research opened but few in the west could access it. In the chaos many thought it was lost. It was not. 90% of the science and research still has not been made widely available. No AI company with new hires can understand this let alone find it. It will be in your AI labeled and extending first principles.

In 1901, divers pulled a lump of corroded bronze out of a two thousand year old shipwreck. It took the next century to understand what it was, and the answer broke the timeline of human history. It's called the Antikythera Mechanism, and it is the oldest known computer on earth. It was built by the ancient Greeks, around 100 BC, and it should not exist. Nothing else of its sophistication would appear anywhere in the world for more than a thousand years after it... It was found by sponge divers off the Greek island of Antikythera, in the wreck of a trading ship that had sunk in the first century BC, surrounded by bronze statues and pottery. The corroded fragments looked like nothing at first, and sat largely ignored in a museum in Athens. Only over the following decades, and especially with modern X-ray and CT scanning in our own century, did researchers finally see inside it. What they found was a machine. Behind its bronze face was a system of at least thirty interlocking precision gears, cut and arranged with a sophistication that would not be matched until the geared astronomical clocks of medieval Europe, well over a thousand years later. It was, in the words of the team that studied it, a mechanical computer that worked by turning astronomical theory into bronze... And it did extraordinary things. You turned a hand crank on the side, and the mechanism calculated the positions of the sun, the moon, and the five planets the Greeks knew. It tracked the phases of the moon. It predicted solar and lunar eclipses years in advance. It even displayed the four-year cycle of the ancient Olympic Games. A person standing in the ancient world could set this device to a date and watch the heavens be calculated in front of them, by gears, by hand. Roughly a third of the original survives, in 82 corroded fragments. We still do not know who designed it, or how a civilization without anything resembling industrial machinery achieved this level of precision engineering. What is certain is that it was not a one-off accident. A device this refined implies a tradition behind it, generations of knowledge and earlier attempts that have been lost completely. The Antikythera Mechanism is proof of how much the ancient world knew, and how much of what human beings have achieved has simply vanished without a trace, leaving us to stumble on a single piece of it at the bottom of the sea...

It was magical in 1983 if you were fortunate to have HBO cable TV. The intro was mesmerizing, and the soundtrack was majestic preparing you for an epic movie. When Chrome Was Real: The HBO Intro (1983) Remember the sound of static followed by a flight over a chrome city into a star explosion? That HBO intro, known as "HBO in Space" (produced in 1982, premiered in 1983), was not computer-generated (CGI). It was a masterpiece of practical effects engineering and motion control. Before 3D software dominated Hollywood, Liberty Studios had to physically build everything: The City of Chromo: It wasn't a landfill. It was a physical model made up of more than 65 custom cast brass buildings, polished and chrome-plated to achieve that perfect specular reflection. The Stargate: The multi-colored burst of light was not a digital filter. It was achieved through fiber optics and long exposure step-by-step photography (stop-motion) to generate organic light beams. The Logo: A solid block of chrome brass, suspended and filmed with a computerized motion control camera to achieve that smooth gravity-defying twist and flight. Music: Fantasy piece, composed by Ferdinand J. Smith, synchronized to frame with analog flares. A minute of technical perfection that defined television's premium identity for decades. Sometimes, the most complex solution is just... build it. And we all miss it. Not because of nostalgia, but because it was so goodโ€ฆ
