Scala-view: Animate streams of images

Previous post used Breeze to animate the sequence of computed images. In this post author wants to describe an alternative that is better suited to animating an image sequence.

Creating forms on your Play application - Part 2

On this second part, we are going to see some more advanced topics: how to do nested forms, how to add your own class to your form, how to protect your forms from some kind of attacks, and the most important: styling your forms!

Typesafe Union-type folding in Scala

The goal of this article is to be able to "match” a union type in a typesafe manner. We’ll start from an ideal syntax, something equivalent to a normal pattern match, and work outwards from there.
ManagedT: Compositional resource management

When bootstrapping a new application, you’d typically like to nicely structure the way resources (which we’ll define in a moment) are acquired. Resources should be allowed to depend on each other, imposing a sequential order on the startup sequence.

Well-Typed Reflections

In this post, I show how to abuse for comprehension and leverage the following syntax to define aggregators, the dual to iterators.

NeoVim + Scala

I am going to walk you through my vim/scala setup. I try to walk a balance between replicating IDE like features and keeping things minimal.

The Man Who Knew Infinity: Coding Ramanujan’s Taxi

Ramanujan was able to see beyond the simple taxi cab number and into the depths of the expression behind it: a³ + b³ = c³ + d³…better known as Ramanujan’s Taxi. I thought this problem was fascinating and wondered how the code implementation would look. Little did I realize there were many optimization layers to this algorithm onion.
