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 time. As the capsule orbited Earth, Globus would continuously update-showing where the crew was above the planet.
No screens. No software.
Just pure engineering.
By factoring in orbital motion, Earth's rotation, and time, the system could accurately track ground position and even help determine reentry timing and landing zones.
It was reliable, self-contained, and didn't depend on external signals-making it perfect for the early space age.
A reminder that long before digital navigation... spaceflight was powered by clockwork precision.

@GiantHotTakes Maybe they can give Matos an extended shot again. Errrr…..uhhhhh, forget that.

I repeat:
The U.S. sent thousands of its 19 years old soldiers to die in Normandy, to free Europe and to end the biggest crime against humanity ever commited - by Europeans.
It was just 81 years ago.
The whole reason, France, Benelux etc. 🇫🇷 exist today is because of this heroism.
My grandparents could grow up in a liberal democracy. Without the U.S. they would be raised at the H*tler Youth.
We Europeans would still be in wars again and again, like 1914, 1866, 1870, 1795 etc.
They brought peace, democracy, liberty and human rights. They invested billions of U.S. Dollars into Europe with the Marshall Fund. They gave us more than we ever had in our history before. They protected us for 7 decades with hundreds of thousands of soldiers against the cruelties of the Soviet Union.
The terror we can see nowadays in Donetsk, would have happened in Bavaria, Bourgogne or the Netherlands in 1950 if there wasn’t the U.S. 🇺🇸
Who do we Europeans think we are to let that nation down, act like bad allies, calling their President names every day on television - and have full confidence we stand better alone. All of instagram is just about, why we’re better than the U.S.
We owe them so much.
We Europeans are most arrogant species on earth. And to cure this we have to face the truth.

Marc Andreessen explains why we are only three years into what is effectively an 80-year technological revolution:
He opens with a blunt assessment:
"This is the biggest technological revolution of my life. This is clearly bigger than the internet. The comps on this are things like the microprocessor and the steam engine and electricity."
But to understand why, you have to go back 80 years.
In the 1930s, the pioneers of computing understood the theory of computation before they'd even built the machines. And they faced a fundamental choice.
Build computers in the image of the adding machine — hyper-literal, mathematical, capable of billions of operations per second, but unable to understand human speech or deal with humans the way humans like to be dealt with.
Or build computers modelled on the human brain. Neural networks.
They chose the adding machine. And that single decision shaped everything — mainframes, PCs, smartphones, every dollar of wealth the computer industry created over the next 80 years. IBM itself is the successor company to the National Cash Register Company of America. The lineage runs that deep.
But here's what makes this moment so extraordinary. They knew about the other path. The first neural network academic paper was published in 1943. Marc points to a remarkable piece of forgotten history:
"There's an interview you can watch on YouTube with the authors. It's him in his beach house, not wearing a shirt, talking about this future in which computers are going to be built on the model of the human brain."
That was 1946. The vision existed. The path just wasn't taken.
So neural networks spent the next eight decades living in the shadows. Kept alive by a small academic movement — first called cybernetics, then artificial intelligence — that refused to let the idea die. And for most of that time, it simply didn't work.
"It was basically decade after decade after decade of excessive optimism followed by disappointment."
By the time Marc reached college in 1989, AI was a backwater field. Everyone assumed it was never going to happen.
But the scientists kept working. Quietly building up an enormous reservoir of concepts and ideas across those decades of disappointment.
And then Christmas 2022 arrived. ChatGPT. And suddenly:
"All of a sudden it's like: oh my god. It turns out it works."
That moment wasn't the start of something new. It was the payoff on an 80-year-old bet that almost everyone had written off.
Which is exactly why Marc's framing matters so much:
"We're three years into what is effectively an 80-year revolution."
Most people are treating AI like another technology cycle — something to adapt to, ride, and wait out. But if Andreessen is right, we are not adapting to a new cycle. We are standing at the very beginning of the longest and most consequential technological transformation in human history.
The road not taken in the 1930s is finally being built. And we have barely broken ground.

Tower Records in San Francisco in the 1980s.
Opened in 1967 & closed in 2006.
Check the photo below to see what that same location looked like in 1966.

This is what Columbus and Bay in North Beach looked like in 1966, a year before Tower Records first opened in San Francisco, at 1175 Columbus Avenue. Now it’s a Walgreens.

@unlimited_ls I hope Hegseth removes him from service. This is a direct attempt to undermine the effort.

BREAKING: America’s top Catholic military bishop says the war with Iran is unjustified and suggests troops may not be morally required to follow every order
The interview is set to air on CBS's Face the Nation on Easter Sunday
'While there was a threat with nuclear arms, it's compensating for a threat before the threat is actually realized,' Archbishop Timothy Broglio, head of the Archdiocese for the Military Services said
'The question might be would generals or admirals have space to perhaps say, "Can we look at this a different way," but having spoken to some of them, they are also in the same dilemma,' Broglio said
'So my counsel would be to do as little harm as you can and to try and preserve innocent lives.'
