"High Fidelity"

A short break on popularity distributions and clustering coefficients.

The novel High Fidelity by Nick Hornby is guaranteed fun. The movie based on the novel, which is located at Chicago, is also great. I also must confess that I got the Top Five fever for a while after reading the book and watching the movie.

Thus, just for your fun consideration, appreciated reader, here is my top 5 ranking for cover versions of songs.

1. "Garota de Ipanema" by RUSH (originally by Tom Jobim and Vinicius de Moraes)
2. "What a wonderful world" by Joe Ramone (orginally by Louis Armstrong)
3. "Have a Cigar" performed by Foo Fighters (originally by Pink Floyd)
4. "Bullet in the Blue Sky" by Sepultura (originally by U2)
5. "Hurt" by Johnny Cash (originally by NIN)

Now, a nice place to find those songs... Hype Machine, a nice tool for search music and video content commented on blogs.

Hemingway and FLP

Yesterday, I have finished reading For Whom the Bell Tolls by Ernest Hemingway. It is not only because the book is written by a Nobel Prize winner that it is worth reading, it is a very interesting and thought provoking book about the human nature. My impression is that the book becomes more and more exciting as it comes to the end.

Anyway, the main goal of this post is not solely discuss my impressions about this Hemingway's book. The fact is that for several chapters the main character faces a dilemma, which is in my opinion the same challenge faced by those building reliable distributed systems, this is explained by a great paper well known as - FLP. :-)

(Un)fortunately, Robert Jordan could not have access, at that time, to the ground breaking paper by Fisher, Lynch and Patterson (Impossibility of distributed consensus with one faulty process) to shed some light (or darkness, perhaps) on his situation.

Definitely, both works are great references...
