  1. When it comes to clustering, depending on the algorithm used, one may have a hard time determining the appropriate k (number of clusters). Some algorithms do not require it, but for the ones that do, such as k-means, you should have a look at the elbow method to evaluate the appropriate k or at the silhouette of objects regarding the clusters.

I never really explained why I started the series “The Best Links of The Week”. I used to have (I still have at some level) a big problem with tabs. I assume you’ve probably already heard of compulsive hoarding, and maybe that’s an easy way to explain the situation I used to have with tabs. Whenever I found an interesting link, I’d open a tab for it and not infrequently I’d open several tabs during the reading of one tab. This along with the fact that I’m a very curious person, there is no surprise that I would always end up with *at least* a few hundreds tabs opened. It’s obvious that I was never able to read them all. Besides, there would always be some great tabs I saved to read that would get lost among the cool but not that important tabs, and that bothered me a lot.
