Emulating ARM on Debian/Ubuntu

You might want to read this to get an introduction to armel vs armhf.

If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.

Running ARM programs under linux (without starting QEMU VM!)

First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux

This is a walkthrough on how to install the MOC command-line music player on OS X. The procedure was tested in Mountain Lion.

MOC on OS X

I waited for years for a Homebrew formula for MOC. I finally found one today, but it didn't work for me. So I decided to try to compile it from source.

Requirements

Here is a list of requirements, taken directly from the MOC README:
