Machine Learning API

I’m currently working on a Machine Learning API (I call it “runemel”). Have a first glance at it on The idea is to create an API that allows people to upload their trained ML models, so other people can use these via the runemel API. Think “Open Source

Note to self: Clojure Transducers

The code presented here is available on github. I’ve been trying to get my head around (and develop an intuition for) Clojure’s Transducers. During that process, I’ve been playing around with them a bit. These are some of the examples that I’ve worked out. I hope this will

Written & published my first ebook

I’ve recently published my first ebook (yeah!). I’ve put quite some effort into it for about half a year or so – including periods in which I’ve not worked too much on it. However, it really took some work to get this book ready ready and it felt awesome when I

What is clean code?

I thought I’d write a little post about what I’ve learned over the years regarding some characteristics of clean code. “Clean” here refers to features that help code being bugfree, or rather “less attracted to bugs” maintainable reusable I think these are the three major aspects developers should ultimately strive for when writing

Java Lambdas

This shall be a brief overview over Java Lambdas. I will try to make a comparison to anonymous functions concepts how they are being used in other languages. As a comparison language, I choose Scala, since it is statically typed (just like Java is). However, Scala provides type inference, which

Tail Recursive Tree Traversal

Once in a while you may be facing the situation that requires you to walk a tree, do some kind of processing on each node and collect a result (or do other things). In case the tree is arbitrarily large and also arbitrarily branched, you have generally two options (as

Clojure Concurrency Basics

This is a basic introduction into the features that Clojure offers regarding Concurrency Programming. It is not meant to be an extensive reference, but aims to give you an idea of what options you have when you need to coordinate multiple threads and mutable state while programming in Clojure. I

Clojure on Google App Engine

There are plenty of posts around on how to run Clojure on Google App Engine. However, most of them are quite dated and as times (and Google libraries) change, I’d like to share my effort of trying to run Clojure on App Engine without losing the major
