C# to Rust Cheat Sheet

The goal of this is to have an easily-scannable reference for the most common syntax idioms in C# and Rust so that programmers most comfortable with C# can quickly get through the syntax differences and feel like they could read and write basic Rust programs.

What do you think? Does this meet its goal? If not, why not?

Mifare Classic - SAK Swapping Explained

What is SAK Swapping

Behaviour has been observered where some system using Mifare Classic credentials will identify with one SAK (0x08/18) on a basic search (Wake up) but when the block 0 is dumped, the SAK appears to be different (0x88)

This is because the SAK reported on a Wake up is not coming from Block 0 but is instead burned into the card, The SAK in Block 0 is merely a Vanity SAK.

If the dump is loaded onto a Magic Mifare Classic that Mirrors the vanity SAK as the actual SAK on Wake up it will tell the system that the credential is a duplicate & to deny access.

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

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)
