IMO, MapReduce is probably the most influential idea from Google. So it was a surprise to see Google patenting it. I learnt MapReduce in my Data Mining course and became a big fan of it. For an open implementation of MapReduce see Hadoop and if you are interested in Machine Learning/ Data Mining using MapReduce see Apache Mahout.For more details on MapReduce, read the original paper on MapReduce. The paper is very readable.
An interesting article on how Yahoo is building a world class Social Science team.
A two part article series on Shannon Limit and Gallager Codes. The first topic is very well known but the second was pretty interesting too ! Most useful was his lecture notes on Discrete Stochastic Processes and Random Processes.
A critical look on Oracle’s Exadata Columnar compression Scheme. The paper is short and reads a lot like marketing but it is sprinkled with some interesting information. Column oriented databases are very very interesting and Oracle is also jumping in with their hybrid architecture.
An interesting article from Google on how they solve the synonym problem. Basically, how to tell computer that these two words mean the same . Their take on synonym is broader (for eg gm = General Motors, Genetically modified etc). They are using some really cool techniques for the identification and disambiguation. I hope Google puts out some paper about these techniques . Cant wait !!
A nice article on how our DNA contains some strains of Viral DNA (or actually, RNA ) . Another reason was that one of the collaborators was an UTA professor🙂
7. YouTube News
YouTube has been doing some good stuff this week –
a. It had some very useful changes to its video page (see The Video Page Gets a Makeover ) .
b. I had already written about how to use YouTube HTML5-ifier to get HTML-5 version of YouTube in this blog post. Now Google has made it official. All you need to opt-in to the HTML-5 experiment of YouTube. See more details at Introducing YouTube HTML5 Supported Videos.
c. Probably, the biggest news is that YouTube is wetting its feet with Rentals and coming into the arena dominated by Netflix, Amazon etc. Currently the catalog is too small, but I hope it is just the start. For more details see Sundance Film Festival Rentals Now Available on YouTube .
they will be able to freeze, fast-forward and rewind the feed, as well as watch replays at any time during the day.
8. US Supreme court Corporate Spending Limit Case
I know this is kind of , off topic to this blog , but still this ruling has me all riled up !! Details are at : Justices, 5-4, Reject Corporate Spending Limit and a cogent argument is in the NYT editorial The Court’s Blow to Democracy . The reasoning seems really bone-headed to me. I cant still believe how they decided that First Amendment applies to Corporations ! Really stretches the my imagination. This only confirms the common criticism that most US judges are politicians in disguise🙂
