The following are instructions for connecting a Bluetooth device for serial communication on Arch Linux using BlueZ 5.31.

Prerequisites

The following packages are required:

The following are instructions for building a GCC cross-compiler for the MSP430. They are based in part on Peter Bigot's post to mspgcc-users.

Back in 2010, I needed some shellcode, so I wrote this. It spawns Vim rather than a shell, so I guess it's technically "vimcode".

It is, of course, null-free. There is a commented version in the test file, but here it is in its entirety:

\x31\xc0\x31\xc9\x99\x50\x68\x2f\x76\x69\x6d\x68\x2f\x62\x69\x6e\x68\x2f\x75\x73\x72\x89\xe3\xb0\x0b\xcd\x80

For some reason, in January of 2009 I felt the need to implement RC4 in Scheme.

Known to work with Racket.

Specify the key and plaintext on the command-line as arguments, and it will output the ciphertext. For example,
