In 2009, a $3,000 desktop beat a multi-million dollar supercomputer. The man behind it never took a dime. And you use his code every single day. 🤯 Meet Fabrice Bellard 🇫🇷 > French programmer. Born 1972. > No Google. No Meta. No hype. Just a quiet job. > 2000 ~ built FFmpeg, largely solo. > The engine behind YouTube, Netflix, TikTok, VLC, Instagram. > NASA runs it on the Perseverance rover on Mars. 🚀 > 2003 ~ built QEMU. > The foundation of every Android emulator and most cloud servers on Earth. > 2009 ~ broke the Pi world record. 2.7 trillion digits. One desktop. > Used a formula he invented himself. > Supercomputers had done less. He did more. > Won the Obfuscated C Code Contest 3 times. For fun. > Released it all free. Open source. No patents. One man. The invisible engine behind much of the internet. Absolute Legend 🐐

3 times 100 in binary is 1100100 it has 3 set bits the loop runs exactly once per set bit, not per total bit n & (n-1) removes the lowest set bit from n on every iteration subtracting 1 flips all bits after the rightmost set bit including that bit itself AND-ing with n clears those flipped bits and leaves everything above untouched so for a 32-bit integer with only 1 bit set the loop runs once for 0xFFFFFFFF it runs 32 times the iteration count has nothing to do with the size of the integer only the number of set bits matters this is Brian Kernighan's algorithm

how many times does this loop run for n = 100? the answer will surprise you the loop does not behave the way it looks take a guess this exact pattern is in K&R "The C Programming Language" exercise section and the Linux kernel uses it under a different name in dozens of places

Can you find the value of x..? Only legends will get this right without a calculator.

@MathGuyTFL 180 m two possible ways to calculate this. 1) h= vt + (at^2)/2; v=0 => h = (t^2)/(2g) = 180 m or you can say that all initial potential energy transforms in to final kinetic energy when it hits the ground. 2) Ep = Ek mgh = (mv^2)/2 => h = (v^2)/(2g) = 180 m

A stone is released with zero initial velocity from the top of a tower and reaches the ground in 6 seconds. If the acceleration due to gravity is 10 m/s², find the height of the tower.
