As this started to mature into a real project, I've moved the code to https://github.com/ebroder/rugdby
(There are tests now!)

I want to write Rust code on my computer (x86_64, Ubuntu 14.04) and produce arm executables. I found hints on the internet, but not a concise set of instructions on what to do. So I wrote them down exactly:
apt-get install g++-arm-linux-gnueabihf
git clone https://github.com/mozilla/rust.git
mkdir rust/build-cross
cd rust/build-cross
../configure --target=arm-unknown-linux-gnueabihf --prefix=$HOME/local/rust-cross
make -j8 && make install

This provides the endian conversion functions form endian.h on Windows, Linux, *BSD, Mac OS X, and QNX. You still need to use -std=gnu99 instead of -std=c99 for gcc. The functions might actually be macros. Functions: htobe16, htole16, be16toh, le16toh, htobe32, htole32, be32toh, le32toh, htobe64, htole64, be64toh, le64toh. License: I hereby put …

This may have seemed like a great idea in 2013, but the repeated "set/clear bits", a.k.a. clamping phases at each level of the hierarchy slowly subtract key strength.
Don't use this as described. Check out Ristretto.
Semi-private keys are an expansion of the traditional idea

Disable YAML parsing in ActiveSupport's XmlMini to avoid a Rails exploit via a XML payload containing YAML type nodes.
I don't know of any apps needing to embed YAML in a XML and getting Rails to auto parse the payload so I think this is a pretty safe patch.
