Welcome to my blog where I write about software, technologies and my adventures related to and beyond those.
*Leila: All sharing shop – Collaborative commons in practice
Today I visited and became a member at *Leila. You can think of it as a “lending library for things”. You can get a wide selection of tools, games, cooking equipment, electronic devices and much more. It works like this: You become a member by providing at least one of your items to the *Leila […]
Gain freedom (almost): Impressions from Firefox OS
I am in the process of migrating services from properitary, closed solutions over to open and libre products. OwnCloud, SubSonic and iRedMail replaced Dropbox, Google Drive, Google Mail and Calendar, as well as Spotify (way smaller library admittedly). A remaining bummer was my reliance on Android with a significant amount of Google services. So I […]
Clojurescript’s Reagent: Using props in lifecycle hooks
I was struggling to get use Facebook React’s props in Reagent’s lifecycle hooks. Don’t worry if you are in the same boat, here comes the solution. My current way of doing this is to use reagent.core/props in the lifecycle hooks. Here is a small working example (based on my work on an application for polytopic […]
Big Data is NOT a competitive advantage
Do you think your company should leverage Big Data? Are you looking for Hadoop and Apache Storm engineers already? Did you evaluate cloud service to run distributed computations and your DevOps team enjoys some good trainings about how to manage those? That’s awesome! Well, as long as you actually need all that stuff: Yes, there […]
Bragging Rights: Marathoner
So far I blogged here only about failing at my first marathon. The lessons learned paid off in the end. Meanwhile I ran two official marathons: My debut in Dresden 2013 (03:55:16) and in 2014 I ran the Berlin marathon (03:55:13). Success is worth mentioning too, right? 😉 Both I was able to finish in […]
Sorting out projects – Starting new ones
Who doesn’t know about having too many projects at hand? Guess I am not different, probably rather on the more excessive side of things here. Having finished my PhD and getting some personal issues sorted out, I feel having capacity and the drive to get my hands dirty again. Among the things I already started […]
Color Duel: A pet project game built with Construct 2
Being an early adaptor for Construct 2, it was about time to get a game built with it out of the door. I think I bought this in 2011 for 30€ or something like that. With an increasing interest in educational apps and new teaching and learning approaches I finally dug into Construct 2, building […]
3 lessons learned from failing at marathon debut
Last year I failed miserably on running my first marathon. Severe pain from shin splints forced me to stop running completely while training for Berlin marathon 2012. I really tried to continue running but that was probably the worst thing to do. Finally I realized I had to take a break. I stopped running completely […]
Karma very slow on Chrome? Don’t run it in background tab!
Very recently I started to use the very nice Karma Test Runner. I really do recommend to check it out. However I wondered why tests ran very slow sometimes (>20s) and sometimes they where very fast (<1s). Quickly I realised the issue was having the Chrome tab in the background: The Chrome tab which was connected to Karma was […]
Image analysis with Clojure and OpenCV: A face detection example
I recently got not only interested in Clojure but also want to utilize it for some image analysis now. OpenCV is a very solid package for image and video analysis. Java bindings have been released for OpenCV at the beginning of 2013. Unfortunately it wasn’t as easy as I expected in the first place to […]
