It is not a coup, this is allowed by the constitution and has the avail from the supreme court. I'm Brazilian, and only the worker's party and their followers call it a coup. The majority of the people want the removal of the current president due to its inability to run the country.
Thanks for the nice article. Peak detection algorithms are indeed required in many engineering applications, so it is good to see that there are different approaches to the same problem.
I just want to add that PeakUtils also support fitting gaussians and computing centroids to increase the peak resolution, allowing for a higher resolution (instead of just finding the indexes). Also, the PeakUtils indexes function was inspired on Marcos Duarte implementation, so those methods have some similarities in the results.
I don't thing that those are the right questions to ask. Most of then expects a 'simplified' answer, like the earth revolving the sun and the Big Bang being an 'explosion'.
