fredrikj.net/blog/2023/04/fl… FLINT furnished with faster FFT: we recently merged Dan Schultz's amazing new small-prime FFT code into FLINT, enabling much faster bignum arithmetic (in some cases 10x faster than GMP).

Why do furniture manufacturers even bother to give you these hex wrenches made of tin-playdough alloy?

Now my ANTS talk is also up on YouTube: youtube.com/watch?v=Un_Mqm2D…

Sharing the most random trivia on reddit and years later someone finds it useful 😊

Nothing brings Swedes together better than waiting for ersättningsbuss.

Kind of fun. I created a minimal mpmath context object (github.com/fredrik-johansson…) around the floating-point arithmetic from FLINT/Arb fredrikj.net/blog/2022/07/ge… and it works:

Compare with this monstrosity of a flowchart that currently decorates the Wikipedia page en.wikipedia.org/wiki/Karats…:

Here is an attempt at a geometric explanation of the Karatsuba algorithm. The objective is to calculate the areas of the three distinctly-colored regions; Karatsuba does this with 3 multiplications instead of 4.

A key ingredient in hal.inria.fr/hal-03714660 is the ability to quickly approximate a real number to high precision by a smooth rational number. For example, here is a 131-smooth approximation of pi accurate to 131 digits, computed with Algorithm 1 in the paper.

Tommy Emmanuel + Joscho Stephan might just be my favorite guitarist pairing. youtube.com/watch?v=EZdy41sW…

Adding more multithreaded algorithms to Arb. Now computing the millionth Bernoulli number in just 5.5 seconds on an 8-core laptop!

New laptop finally arrived, 7 months after placing order. Old laptop was already 7 years old then. Well, I can now test FLINT 7x faster!

...or garbage disposal. Well, no problem for me personally to do obstacle courses; just saying.
