Colt Frederickson and I gave a talk entitled "A billion records a month isn't exactly a lot of data these days" about what we've been working on to the February Montana Programmers Meetup in Bozeman.

I provided some background on what MapReduce, HDFS, HBase, and Oozie are. Colt gave an example of how we use those technologies. I closed up with some of the lessons we've learned.

If you use the HTML5 player for YouTube, you can use the UI to increase the playback speed to 1.5 or 2.0.  While I do like my talking heads to talk a bit faster, I don't like them to take a full 50% faster.  This bookmarklet will allow you to set the playback speed to an arbitrary value.

javascript:%7Bvar%20v%3Ddocument.getElementsByTagName(%22video%22)%5B0%5D%3Bv.playbackRate%3DparseFloat(prompt(%22Playback%20rate%3F%20%5B%22%2Bv.playbackRate%2B%22%5D%22))%3B%7Dvoid(0)%3B

Here's the easier to read version of the same code:


{
  var v = document.getElementsByTagName("video")[0];
  v.playbackRate = parseFloat(prompt("Playback rate? ["+v.playbackRate+"]"));
}
void(0);
