[ ] - Something with MessagePack: https://github.com/msgpack/msgpack/blob/master/spec.md
[ ] - Retro Computing
[ ]     * Atari ST
[✓]         - Get an emulator up and running
[✓]         - Learn how to install and use development tools (Devpac3, Hisoft C, etc.)
[✓]         - Copy sample ASM and C programs and play with them a little to get familiar
[ ]         - Write a simple ASM program from scratch
[ ]         - Write a simple C program from scratch
[ ]         - Export a C function interface from ASM
[ ]         - Write a C program to call an ASM-implemented C interface
[ ]         - Start playing with graphics?
[ ]     * ASM/C interface on Altair 8800 emulator
[ ]     * ASM/C interface on Commodore 64
[ ]     * ASM/C interface on Commodore Amiga 500
[ ]     * ASM/C on Nintendo 64?
[ ]     * Turbo Pascal
[ ]         - Get Turbo Pascal running. Requires a DOS environment.
[ ]         - Get a Turbo Pascal program building.
[ ]         - Look into getting Turbo Pascal running on Linux?
[ ]     * Turbo C
[ ]         - Get Turbo C running. Requires a DOS environment.
[ ]         - Get a Turbo C program building.

[ ] - Graphics
[✓]     * Linux Framebuffer programming (software graphics without X)
[✓]         - Hook up some sample code which interacts with the framebuffer
[✓]         - Disable text cursor when showing framebuffer
[✓]         - Investigate usage of fbset (http://linux.die.net/man/8/fbset) to change fb rez
[ ]         - Try Framebuffer graphics on Arch Dell Mini 10 machine (with no X running)
[ ]         - Select aspect ratio and then scale to fit actual display.
[-]           * eg.: If program's internal res is 1920x1080 and display is 1366x768, then both have an aspect ratio of 16:9 so we simply scale both dimensions by ~0.711.  If the aspect is different then we can either do a zoom, or render black bars to compensate.
[ ]     * DirectFB (Probably a dead-end now!)
