20 million digits of pi in under a minute with Julia

I recently discovered a relatively obscure algorithm for calculating the digits of pi: https://en.wikipedia.org/wiki/Gauss–Legendre_algorithm. Well, at least obscure compared to Chudnovsky's. Wikipedia notes that it is "memory-intensive" but is it really? Let's compare to the MPFR pi function:

function gauss_legendre(prec)
    setprecision(BigFloat, prec, base=10)
    GC.enable(false)

Mifare Classic - SAK Swapping Explained

Term	Meaning
WUP-SAK	SAK Value found during the Wake up & Anti-collision process, what you would see reported from a basic search.
Vanity SAK	SAK Value represented in Block 0 of a Mifare Classic, on legitimate cards this does not inform the value of the WUP-SAK.
Magic Card	An illegitimate card capable of changing it's UID; some magic cards are also able to change other values such as ATQA/SAK.

wf-recorder

With wf-recorder it is possible to record one output. When ffmpeg is compiled with sdl support, then it is possible to use "sdl" as the muxer and replay the recorded video instead of writing it to a file.
