  I was intrigued by the method of piping pixel values to MPlayer as a frontend. I'll definitely be using that in future projects.

  It makes use of this video format, which seems almost like a video equivalent of the PNM image format: https://wiki.multimedia.cx/index.php?title=YUV4MPEG2

  I wish there was something similar that used RGB though.

  While it's interesting how you can accelerate Ruby, 150 fps is still _awful_ for a NES emulator on modern platforms.

  It kinda shows how bad Ruby's performance is compared to most other languages.

  How does truffle enhance JRuby to create such a dramatic performance improvement?

  can we predict that jruby+truffle, will be usable for ruby gems in the next few years?
