The Stupid Hackathon is a one-day event where participants conceptualize and create projects that have no value whatsoever. Me and Memeleader made Chat Roulette Kastanjett – a service for all castanet players who want to talk to other castanet players over castanet morse code. We made a small chat website (with the help of socket.io and Heroku), wired up castanets with a micro Arduino controller running morse code debugging code. And we won a prize!
Torch is a scientific computing framework with wide support for machine learning algorithms. Andrej Karpathy has an excellent blog post explaining recurrent neural networks (RNNs) and character level models. With his sample code for Torch it is very easy to get started creating your own RNN by using text from a specific domain. This model learns to predict the next character in a sequence. The model can be used to generate text character by character that looks similar to the original training data. Continue reading
The Gothenburg University Library has digitized several years of sheet music from a publication called Musikaliskt Tidsfördrif (“Musical pastime”). The first issue from 1790 contains a short Polonaise. I transcribed it in MuseScore and generated an audio file. Continue reading
Empowering everyone to evaluate usability can improve the digital workplace. Here is how you take the first step with userpoll.io. Continue reading
A small hack to simplify the application for temporary parental benefit for care of children from the Swedish Social Insurance Agency (Försäkringskassan). Typically this involves multiple steps in a web browser. Now, moving a doll to a square and the computer will send relevant information to kindergarten and the social insurance agency.
(Cunningly illustrated using patent application art). A small Python script monitors twitter for the phrase “I hate lego”. Upon finding a matching tweet it sends a signal to an Arduino board that turns a servo pushing a small lego figurine over the edge of a table. Live example here (at approx 7:30). A hack for the Make All event in Stockholm. Continue reading
A small crab attacked my GoPro camera.
Data about public sector spending is often hard to understand and compare. Statistics about government is often presented in tables. In this hack I have used open data from Eurostat (the EU statistics agency) about government expenditure for a set of countries and rendered sets of boxes in a Minecraft world. This makes it possible to explore the data by walking (flying) around the world. Continue reading

As open data is gaining momentum an increasing number of organizations are thinking about ways to make their data available for others to use. Here are some thought on how to approach design issues when making open government data available. Continue reading
One can not help but wonder how many Harvard freshmen would pass this exam today. Click to see the Harvard admission document.
With the increasing availability of big/open data more people discover a need to make it understandable. One way of understanding data is by looking at it. As I have received a lot of questions lately here is a roundup of tools you can use to create visualizations of data. Continue reading
