  • How to organize a CoderDojo

    FrOSCon 2016 20. August 2016

    CoderDojo is a worldwide initiative to teach kids how to program. Each one is organized individually and the organizer can choose how to do it.

    I’ve been organizing the Dojo in Cologne for about two years now. In those two years we’ve grown from Dojos with four or five kids to Dojos with 14 (and sometimes even more than 20) participants each month.

    I will show you what we do at our Dojo in Cologne and share tips on how to organize a Dojo :)

  • Codegolfing

    Munich Rubyshift März 09. März 2016

    Code golfing is an interesting sport: You try to write a program in the fewest characters necessary. Do you want to ship this code to production somewhere? Probably not, but just by trying this exercise you will learn a lot about your favorite programming language. You will also be surprised by how much you can do in just a few lines of code while the constraints will stimulate your productivity. Ruby is surprisingly good for golfing due to its Perl heritage.

    In this talk I will tell you a bit more about code golfing and then dive into some code I have golfed. I will show you some tricks I learned and how the desire to shave off a few more characters every time leads to new features in your tiny program that you thought would not fit in such a tiny program.

  • FP vs. OO

    Blog-Post 14. Dezember 2016

    I recently came across a tweet stating that there were no people who “defend OO vs. FP” that actually used FP in real projects. This is not the first time I came across statements like this (like in a blog posts portraying functional programmers as being higher on the “evolutionary ladder” than object-oriented programmers). Another claim I hear again and again is that “only Functional Programming can solve the problems of the modern age (like multi-core computing)”. I disagree with both claims.

  • ROCA vs. SPA

    Blog-Post 05. August 2016

    Currently, a lot of companies are migrating from Desktop applications (mostly written in Java) to Web applications for their products as well as for their internal tooling. When they start with this process they often ask themselves: Which technologies should we use to build our Web application? Should we use Angular.js or React? Or should we go with recommendations like ROCA instead of a Single Page Application?

    Podcast-Folge 07. Januar 2016

    In dieser Episode unterhalten sich Lucas Dohmen und Stefan Tilkov über Redis, eine NoSQL-Datenbank aus der Key-Value-Kategorie, die sich insbesondere durch ihre hohe Geschwindigkeit und ihre intelligenten Datenstrukturen auszeichnet. Dabei werden nicht nur die Features aufgezählt, sondern auch praktische Hinweise zum Einsatz gegeben.
