Ok, you need a bunch of images and don't have to time to read API docs, request a key, write scripts, reread API docs, etc... sound familiar? Then you might like this little javascript trick.
Read MoreComplexity CHEATSHEET
/
This is the first entry in a series of cheatsheets that I'll be posting more of soon. This poster includes a compactified review of computational complexities of all the basic data structures and algorithms.

/
This anti-tutorial provides a magic one-liner (a-la brew's installation) to get all the common libraries setup and configured (on P2 class machines running Ubuntu 16.04) in Amazon Web Services.

Primes in the Matrix

Mind-bottling to behold (yes that’s a Ron Burgundy reference), this 2D automaton both generates and displays the primes.
Read MoreComputer Language Timeline

Today it seems everything in the ML field is Python. Amazingly, this animation shows life wasn’t always so monolingual.
Read MoreGraph Isomorphisms
/
Two graphs are isomorphic if there is a renaming of vertices that makes them equal. In other words, if you are given two different drawings (or embeddings as nerds are apt to say) of the same graph, you can always deform one into the other.
Read MoreThe Ultimate Print Statement
/
This macro is a must-have for your Objective-C/C++ debugging toolkit, and replaces all print statements.

Found myself with a few extra hours (sick at home today) so I decided to see how easy it would be to simulate a 3D TV with my webcam. This amounts to interpolating a scene's view vector (where the camera is) from the motion of your head in the video.
Read MoreExpression Browser

I'm a huge fan of Clojure and lisp in general, but when dealing with every large expressions, there is much to be desired in terms of presentation. Here is a tool I just built to quickly identify the index of a sub-expression in the full form of a normal expression tree.

Spritz is a Boston-based venture in the tech industry (they raised $3.5M) whose SDK promises to evolve reading into the wearable devices century.
Read MoreDendrogram
/
In case you didn't know, I love data visualization. The dendrogram is one of my favs - it's a tree diagram frequently used to illustrate the arrangement of the hierarchies. Dendrograms are often used in computational biology to illustrate the clustering of genes.
Read MoreJumping the GAP
/
My friend Alexander Hulpke at Colorado State University in Fort Collins was one of the principal authors of the computer algebra system GAP. This is one of my favorite discrete algebra packages and is the golden standard for any computational group theory.
Read MoreCardioids for Valentines Day
/
A cardioid is a plane curve traced by a point on the perimeter of a circle that is rolling around a fixed circle of the same radius. The typical technique for constructing them is by complex equations, but here is another technique for producing the pattern that only use simple straight lines.

I find computer-science fictional interfaces e.g. alien clocks, rather exquisite. The timepiece above is a favorite of mine. The countdown graphic is displayed on the villain's trilithium missile launching platform in the movie Star Trek Generations.
