plan 4.29

I had some free time today and watched the soccer game. MU was really good and Arsenal did not make it today. I still insist Arsenal will win in the semifinals. Go Arsenal! Goal! Goal!

Here are about some interesting posts in kdnuggets. List several here.
One is about the performance comparison between the mapreduce and the parallel database. The paper indicated that parallel databases has a better performance than mapreduce. I have not look into that paper, but I guess mapreduce may achieve a better reliability and fault tolerance, and this is the main reason Google deployed it. I will go on to look at this topic.

The other is about a interesting application about the cloud computing. This is about Google again. I have to say I am not a fan of Google, but some of its applications are really interesting and worth trying. Google presented a platform called Google App Engine, where developers can build their own apps on this. If you need more resources (hard disks, cpu cycles...), you can pay Google and get things you need. Current two languages, java and Python are supported. Interesting.

Will cloud computing be the next hotspot in the data mining communities? It might be true when we are talking about the pegabytes of data, where large amount of computing resources are needed. Privacy preservation is an issue in cloud computing. Any way, this trends is worth tracing in the future.
