Just got a movie in 3D Half/Full SBS MKV and trying to play it with VLC 2.0.5 just show up the 2 images side by side. One solution is to watch it as regular 2D movie by using the script below:

#!/bin/bash
#
# VLC 3D, version 0.2, 2013-04-03 by Sébastien Grosjean
#
# Allow to watch 3D Half/Full SBS MKV files in 2D with VLC 2.0.5
if [ -n "$1" ]
then
  /Applications/VLC.app/Contents/MacOS/VLC --video-splitter=wall --wall-cols=2 --wall-rows=1 --wall-element-aspect=16:10 --wall-active=0,1 --monitor-par=1:2 "$1"
else
    echo "Usage: Pass the 3D SBS mkv file as an option."
  echo "For subtitles, use :"
  echo "- right align (VLC > Preferences > Subtitles & OSD > Show All > Input / Codecs > Subtitles codecs > Subtitles > Subtitle justification > Right)"
  echo "- and smaller font (VLC > Preferences > Subtitles & OSD > Display Settings > Font Size > Smaller)"
fi
exit

Notice the work around for subtitles, making them smaller and right aligned.

Rails 3.1+ and the Asset Pipeline is excellent to minify, merge, and deliver assets, however it's good to also leverage browser caching.

Using nginx, you can set a far future expiration header like this:

server {
  location ~ ^/(assets)/ {
    expires max;
  }
}

PNG Optimization

It's always good to save a few bits when you deliver images on the web, a lot of information can be stripped out of an image without quality loss. To do so on OS X, currently Mountain Lion, I like 2 options:

Batch Convertion

Using ImageOptim

Command line

Using pngcrush

Install

brew update
brew install pngcrush

Usage

pngcrush -rem allb -brute -reduce favicon-32x32.png favicon-32x32-crushed.png

PNG convertion to ICO

Install

brew update
brew install png2ico

Usage

png2ico --colors 16 favicon.ico favicon-32x32-crushed.png
