Convert Video to mp3
Let's all be honest for a moment: we've all ... not paid for ... music. Whether it was via a file sharing app like Kazaa or Napster, or it was downloading and seeding on bittorrent, or maybe even downloading a music video and ripping its audio, we've all pulled some "gangsta shit" to get a track or two. You should only feel ashamed if it was Nickleback. And hey, there are times when you legitimately want to pull audio from a video...though I can't think of any.
If you do want to pull the audio of a video file, for whatever reason, you can do so easily with ffmpeg. Let's use ffmpeg to take a downloaded YouTube video and rip its audio into and MP3:
ffmpeg -i music-video.webm -vn -ar 44100 -ac 2 -ab 192 -f mp3 music.mp3
Using the command above, we take the source video and output its audio to mp3 with a 192kb/s bitrate.
There are in-browser tools and websites you can use to rip audio from YouTube or other video files, but ffmpeg is quick, simple, and hassle free. You can also replace "mp3" with other audio formats if you so choose!

One of the web components I've always loved has been Facebook's modal dialog. This "lightbox" isn't like others: no dark overlay, no obnoxious animating to size, and it doesn't try to do "too much." With Facebook's dialog in mind, I've created LightFace: a Facebook lightbox...

Feature detection via JavaScript is a client side best practice and for all the right reasons, but unfortunately that same functionality hasn't been available within CSS. What we end up doing is repeating the same properties multiple times with each browser prefix. Yuck. Another thing we...

One of the reasons I love AJAX technology so much is because it allows us to avoid unnecessary page loads. Why download the header, footer, and other static data multiple times if that specific data never changes? It's a waste of time, processing, and bandwidth. Unfortunately...
In case anybody is not into command line, there is a UI for this conversion,
