Congratulations to India, to Prime Minister @nardendramodi and to the scientists & engineers on this important technological achievement after many years of development
This reactor will use much less nuclear fuel than other reactors and lay a pathway towards a closed fuel cycle
When Andres Freund, Linux kernel contributor & Microsoft engineer was debugging slow SSH logins on his Debian machine in March 2024, he noticed something weird:
liblzma (part of XZ Utils) was using way too much CPU power, so he kept digging, and what he uncovered was a multi-year supply-chain attack!
An attacker using the name “Jia Tan” had spent two years slowly infiltrating the tiny XZ Utils project, a compression library used by virtually every major Linux distribution.
The backdoor wasn’t in the source code. It was hidden deep inside the build scripts. It would have given the attacker remote root access on millions of servers the moment a specially crafted SSH key was used.
Freund caught it days before it would have shipped in Debian, Fedora, Ubuntu and more.
One man, one anomaly, one routine debug session saved the internet from a potential catastrophe.
Respect!

In 1954, a young scientist named Homi Bhabha stood before India's parliament.
He made a bold promise:
"Within 10–15 years, nuclear energy will be cheaper than any other source."
India had no uranium. No reactors. No money.
He had only a dream and a 3-stage plan.
That plan started executing last night. 🔥
That's right! We went beyond the LCD pixels of the GBA for the wild compo! My recently bought DS Lite finally had a good use.

Artemis II crew is thousands of miles away from Earth
And they’re asking ground crew for help because they have two versions of Microsoft Outlook open and neither is working
This scene is now canon 😭
Do you have intuition on fp precision?
float16 - tennis court at 1 inch
float32 - small city at 1 mm
float64 - continent at 1 nm
float128 - supercluster at 1 nm
float256 - observable universe at Planck length
Now you have!
Why did the US ban this number in 2001? It sounds insane, but 25 years ago, the Motion Picture Association of America was genuinely trying to delete this number from the internet.
You see, back in 1999, a teenager in Norway named Jon Lech Johansen wrote a piece of code called DeCSS.
It cracked CSS, the encryption on DVDs. Suddenly, anyone could copy a movie with the click of a button. It was a nightmare for the movie studios.
They went nuclear. They sued the hacker magazine 2600: The Hacker Quarterly.
They threatened Slashdot, and their lawyers fired out cease-and-desist letters to anyone hosting the code. They called it a digital burglary tool.
But the internet found a loophole.
A computer scientist named Phil Carmody realized that computer code is just binary ones and zeros.
And you can treat that string of binary as a single number. That way, you get a really, really big integer—which is the illegal code.
But Carmody knew that just finding any number wasn’t going to be enough, because the government could still ban a random number.
So he needed a number that science would be forced to protect. He needed a prime number.
You see, the University of Tennessee maintains a prestigious academic database called the Prime Pages.
It records the 5,000 largest known prime numbers. Carmody realized that if he could turn the illegal code into a record-breaking prime number, the university would have to publish it.
His first attempt was 1,401 digits long. It was prime, but too small.
It didn’t crack the top 5,000 list. It wasn’t mathematically interesting enough to save.
So, he hacked the math.
Use this formula:
K × 256^N + B
Now, K is the illegal code part. 256^N is the mathematical equivalent of adding useless zeros at the end—like making a book longer by adding blank pages. It doesn’t change the actual content inside.
So, he kept adding “blank pages,” shifting the number, until he hit a mathematical jackpot—a 1,959-digit monster.
This wasn’t just illegal code anymore. It became the 10th largest ECP prime number ever discovered at the time.
It was checkmate.
The number was immediately added to the university database. For the MPAA to ban the code now, they would have to order a university to delete a scientific record.
You can’t censor mathematics.
