The workday is starting to wind down slowly. I have been doing some cosmetic changes and running tests on a medical storage server. No matter what you change you must always run tests to make sure all is well.
On my last post I covered Dijkstra’s algorithm for shortest path. Shortest path implies distance and not number of vertices traversed.
The motivation for this post is the Coursera class “Graph Analytics for Big Data” by the University of California San Diego I am currently taking. One of the algorithms that we briefly touched was shortest path between two nodes by Edsger Dijkstra.
The algorithm comes in different flavors. One can compute the shortest path between two nodes, the shortest paths between all nodes, among others. In this case I just went with the first approach. Continue reading “Graphs – Shortest Distance Paths”
The past weekend was kind of cold in the Twin Cities area of Minneapolis and St. Paul. Seems like winter a somewhat ahead of time.
In the past few months I have been spending time learning and experimenting with machine learning (ML) and Big Data. Machine learning seems to require a lot of properly cleaned samples. This is one more case when garbage in implies garbage out. That said; the first step is to collect data. Data can come from different sources i.e., databases, files, public repositories, the Internet, etc. Data can be collected from the Internet in different ways. In general one can collect data from the internet using two main approaches: web scraping and via an API. I will cover both of these approaches in the following posts.

It is Sunday again, seems like last week came and went by faster than usual.
When I browse YouTube videos on my phone, I tend to run into some that I would like to watch and if possible experiment with the subject. This post is associated with a video by Irfan Baqui. It is nice to get a challenge, understand what it is required, solve it and see how a fellow developer comes to the same solution using a different and in some cases the same approach.
