Its always fun to play with prime numbers. Why not. In math they mean a lot, in computers they are important, and in recreational mathematics they are… ahem… interesting. Ulam Spiral In 1963 mathematician Stanislaw Ulam published this spiral in Martin Gardner’s Mathematical games in scientific american: A small piece of math history. From that […]

The Hilbert curve is a neat fractal that can turn a single line into a square surface (see gif above which was kindly stolen from wikipedia). An interesting behavior of Hilbert curves is that locality is maintained, meaning that traits near each other in the line cluster together when mapped onto a Hilbert curve. Hilbert […]

Motif ALTernative Exons Scanner Enrichment of RNA-Seq (aka MAltESERS), is a novel bioinformatic tool that can predict domain changes from alternative splicing. But what is alternative splicing? Alternative Splicing While genes in prokaryotic organisms are single units of expression for a single protein, eukaryotic life developed a more complex system for protein synthesis using alternative […]

Have you ever considered scatter plots to be a tad boring? Do you love the patterning of cathedral stained glass? Well, besides aesthetics, there are cases in which a scatter plot might not be the best option to represent data. What if you are more interested in the spatial distribution of some variable? Some points […]

Computational protocols can be quite long and confusing. It is useful to keep them in a script. But we might not want to run the script from scratch every time (if we already have intermediary files). Make is a tool originally designed to automate the building of executable programs and compiling their libraries. Make relies […]

A simple and fun no GUI form to browse and read your Zotero library.   Usage: zot [options] use -r to refresh and sync zotero library. Add query to search your database. Search results will be shown alongside an index number (if asterisc next to number then url is missing) add -n option and index number […]

I was trying to go to sleep when all of a sudden I started thinking about Fermat’s last theorem. This theorem relates to Pythagoras, If n=2 then we get the pythagorean theorem. If n=2, some results have all rational numbers such as a triangle with sides 3,4, and 5 : And with n=1 all solutions […]
