Open Data Hackathon February 2013

On February the 23rd the datalove university group participated in a global Hackathon centered around Open Data. We gathered within a room at the university and worked on different projects all day. At peak level we were around 17 people: university students and personnel, students by the university of applied sciences and local politicians. We organized enough food, coffee and stuff for everyone and spent a nice day working on many different projects. Mainly to highlight:

  • Falco worked on updating the LiveMap, which we have created about two years ago in an 48hr hackathon. For most of us this had been the first bigger node.js project and so it was time to correct some faulties. To paraphrase Stefan: “While looking for better ways on how to do such a project, I only found other people who forked our stuff.” Well, we are not entirely certain, if that is a good thing ;).

    Some Open Data activists from Cologne are currently adapting the project to their city: schienenliebe.de. It is always very nice to see other people being able to build upon your work!

  • Benjamin took use of the shape files (= geodata of local city districts) for Ulm. We gathered this data under a free license about two years ago, but never had any use for them — until now!
    Check out Click that ‘hood!
  • I took the time to work on an idea which I had in mind for a long time: visualizing different facilities within Ulm which are currently open, on a web based map. This can be used to e.g. find out which bakeries in the inner city are still open on a Saturday evening. The application is online via oeffnungszeiten.ulmapi.de.

    The opening hours data is gathered from the Open Street Map project. I plan to regularly export it from there, although I first have to manually correct some of the entries, since not all of them are valid. I also plan to add new opening hour entries to the map, though I am not yet entirely sure about how to approach that.

  • Stefan is working on visualizing the household budget of Ulm. The respective data has been made available to the public under CC-BY in the meantime. If you have any knowledge on Doppik calculations, I am sure he would appreciate help!
  • Some friends were brainstorming about network visualizations considering the university. When I heard of the idea I was quite enthusiastic and went to talk to the local network administrators. As a result we got a nice data treasure: sanitized log data of all (~360) access points on the university terrain over the duration of one week. Under ODbL v1.0. _This_ is quite nice. The data is available here. I spent nearly all of the Hackathon writing a parser for the data. When you have 76 MB ASCII stuff (> 500 000 entries) a database is worth it. In the meantime the parser is finished but we are still missing geolocations for the access points. For this purpose I wrote a very simple web application to crowd-source the process of collecting geolocations for all access points. But this (and the resulting visualizations) are material enough for one separate blog post, once the project is finished!

The sourcecode for most of the projects described is available online via GitHub, either on github.com/UlmApi or on github.com/cmichi.

Looking back on 2012

As every year, here comes my retrospect for the last year. I haven’t written much lately. This is mainly due to a big load of stuff I had to do, but also to a lack of enthusiasm that I have been experiencing since some months. Didn’t get around to get involved in as much stuff, as I normally do. I am still not back on track but really hope that this will come back. I think the reason for this is mainly the Bachelor thesis, which I wrote in the second half of this year. I normally work on lots of different things, but my bachelor thesis (which is finished by now) forced me to put all focus on it and discard everything else. I am really not made to force myself into doing something and thus the greatest challenge was not a technical, but mere a personal one. But as I learned from Dexter: it’s all about getting back to your routines if you lost track of yourself ;-).

The first half of the year though was absolutely amazing. I traveled a lot, got to know many many different people, started to get more spiritual and collected a lot of new experiences which have deeply influenced me.

Most interesting art project wich I discovered
youarelistening.to is a website that creates the “sound of a city” using ambient music and online available police and fire rescue radio streams. Together with a nice night photo of the city this makes an incredibly cool working environment. Especially when projected on a wall via a beamer. This reminds me of a quote from Cory Doctorow’s book “Makers”, that stuck with me: “[…] This thing wasn’t invented. All the parts necessary to make this go were just lying around. It was assembled.”. I think much more cool stuff can be built from the stuff that is already existing out there.

Blog post
The blog post I enjoyed reading most was “I introduced my 5-year-old and 2-year-old to startx and xmonad. They’re DELIGHTED!“. A father has started to introduce his sons from an early age on to Unix. The whole series is worth reading, but in this entry he describes how he introduces a graphical environment. Since he has just told them the basic commandline stuff, they have never even seen a graphical environment up to this point, .

Video
If I had decide for one it would be Where is your Wilderness. Even though, I have a different view on religion, I still can relate to the passion of this filmmaker to create an awesome piece of art.

The music video I liked best was Audioslave – Doesn’t Remind Me, a true piece of art.

Best Experience
I was living in one of the dorms before I started moving in with friends. Once I quit my contract there I had one month to bridge between the two flats. Several people offered me to stay at their flat for the month, but I decided to take this as an opportunity and live one month without a flat. Jumping from couch to couch, sleeping around at different homes.

I ended up spending most of the nights at totally different places of various friends, at one point I literally lived within the university for some days. This works really well by the way — you have everything there, showers, breakfast, meals, sleeping possibilities, etc. :).
However, the best place I stayed at was at meillo’s. He lives in a rural region outside of Ulm. A relative of his owns a milk farm, which resulted in fresh milk each morning and nightly tractor rides. Nice memories.

Best Decisions
Starting to live together with friends. The last months living with them has been A+. I can’t imagine anything, that would make my living situation better. Everything is 100%.

Kate got me into attending a Creative Writing course at university. This has proven to be a very good decision and I have done a lot of creative writing in the past months, even compiled a small shortstory collection with friends. Though, I am not yet (mentally) ready to publish anything here.

Lessons learned
It got clear to me that at one point the question with which technologies I want to work, shifts from a technical to an ethical question. For me this resulted in replacing my work environment with mostly free software and discard the MacBook. Also I replaced DeviantArt with my own MediaGoblin instance and replaced last.fm with libre.fm.

Also I can not emphasize enough how important it is (at least for me) not to wait for other people. If you have a project idea or want to start something, just do it. Don’t constrain yourself with other people lack of time/motivation/flow.

From a technical point I learned that a dedicated root server is really worth it. Together with friends I rented a server. At first I was not sure, if I was going to take a lot of use from it, but now I connect to it daily. I use the server mainly to sync repositories on different machines, share files, for usenet stuff, to host a jabber server, to host web stuff and to have a machine which regularly performs maintenance tasks such as cleaning my mail.

Thing that stuck with me most

The definition of hell: the last day you have on earth, the person you became will meet the person you could have become.

Best advice
Since I am always torn between decisions, Elena told me to just imagine myself in a month, a year or five years from now. What would I then (in retrospect) consider the best decision? I have found this to be quite helpful.

Book I enjoyed the most
I really enjoyed reading the “autobiograhpy” of Steve Jobs, written by Walter Isaacson. Although I have a different view on the politics Apple represents today, I can definitely identify with the original goals of the company. Even though I have been very interested in the Apple history and a big enthusiast for the last years, the book still was very interesting and offered many insights which other biographies were missing.

Coolest project
When we moved in together I thought it might be cool to have something that encourages innovation, encourages people to constantly bring new cool stuff to the flat. So for this purpose I have built a prize, from wood and plastic. A cup actually: the golden pineapple!
Each week we consult on the best innovation for the last week and the respective person gets the golden pineapple for one week. The prize doesn’t necessarily have to be given to people living in the flat, but can also be given to external people (which it has been).

Even though we can’t keep up with giving the prize to a different person each week, the rate of innovation is still constant.

Best photo I shot
The photo I am most proud of is this shot of Kate which I took on a trip through Scotland. The lightning has not been altered, this was all “natural” light by the environment. Also I am really satisfied with the photos I took for various insititute websites at university (see here).

Interesting articles
From a technical point of view I liked the article “Looks Like It!“, a great explanation of perceptual hashes, a way to determine how similar two pictures are.

From an emotional point of view the anger in meillo’s article “der taegliche kampf” (german) on the “modern” university education system is something I can greatly identify with.

From a curious point of view I loved the article and video “Getting high on Krystle” from the Vice magazine.

Podcast
I love the Pentacast, most notably I liked the Responsible drug usage podcast (language: english). Also I like the Soziopod (language: german), most notably the one on Karl Popper.

Best learning resource
The VI manual offered quite some insights for me. I feel as if I have a much more basic understanding of the tool, now that I have read through it.

Project I donated most to
Torservers.net is an organization with the balls to run Tor exit nodes. Awesome!

Most helpful tool
youtube-dl is a python script to comfortably download stuff from youtube, vimeo, soundcloud, etc.. Pass an URI to the script, get a video/audio file.

Photo
I found this photo a while ago and the shere intensity blows me away everytime I look at it. It shows an explicit birth scene and should be considered NSFW: A star is born, http://www.flickr.com/photos/krisvdv/5894742041/.

Music
I have started to get into music from the sixties and seventies a lot. It is incredible how much creative work has been done in those two decades! I have started to heavily listen to Pink Floyd, Led Zeppelin and The Alan Parsons Project. All bands that I have known for a long time, but the music just didn’t work for me — until now. For the first time I have found an access.

Another progressive rock band which is more up-to-date and which I have become to like over the course of this year is Tool. The self understanding of the band speaks to me: “[…] we are … your tool; use us as a catalyst in your process of finding out whatever it is you need to find out, or whatever it is you’re trying to achieve.” (Keenan)

Other albums which stand out: Fever Ray. The hours I have listened to this album: countlesss. Also my bachelor thesis probably could not have been written without Eminem’s album Recovery. An electronic band that I have come to like very much is M83.

The score I liked most was the Blood Diamond Score by James Newton Howard.

And at least I just have to mention Prinz Pi, whose music I have come to adore very much.

From last year
I had planned to change my setup to a much more Unix-like setup. I can report, that I have succesfully achieved this :)! I now use a heavily commandline oriented workflow. Tools that I most often work with include tmux, ksh, nvi, mcabber, vimpc (as a mpd client) and git (which I want to replace with hg).

The rough plan for 2013
I plan to stay within Bachelor for one more semester, earn some money, already earn some credit points for the Master, maybe get a scholarship. In the later half I plan to start the Master’s program here in Ulm.

Creatively, I want to get into sewing and music. Already picked up a sewing machine and am starting out with the basics. My big goal is to sew a (very simple) jacket in 2013. For the music part my goal is to finally get something started. On the creative writing part I would like to write a bigger piece, a book, basically. Have some ideas, fictional and non-fictional, will see. Another thing that has been bothering me for a long time is that I really want need to write a decent music visualizer.

Travelling through Scotland

 
 
 
 

For three weeks in August I have been traveling through Scotland with five friends, though not all could stay until the end. For the first week we stayed in Edinburgh to visit the Fringe Festival — a broad cultural event where the whole city gets occupied by artists, bands and comedians. Every last room is used to run shows and you see awesome costumes on the street each day. The event was very nice and the city is quite awesome.

Universities: We have been to the university in Edinburgh quite a few times and we have spent some days in Glasgow. I really like the look of the universities in those two cities, they totally remind me of the Harry Potter movies (see for yourself). Also I found Eduroam to be quite a valuable technology! Opposed to Ulm, the university in Edinburgh is distributed over the whole city — which also means as a student you have internet access via Eduroam in a lot of places.

After the week in Edinburgh we rented a small car and went on a roadtrip through Scotland. This turned out to be a really good decision. We would never ever have seen such a large part of the country without a car. So for two weeks we traveled through Scotland, visiting different isles and distilleries, doing a lot of wild camping and sometimes staying at various hostels. As we have neatly evaluated the perfect score for driving through the highlands is the Game of Thrones Theme.

At one point we left the car, took our tents and stuff with us and wandered into the nature. The nature! Beautiful, stunning nature! The law in Scotland in case of wild camping differs very much from Germany, in general you are allowed to camp wherever you want as long as you leave no trash, disturb nobody, don’t stay for months and don’t camp directly near a house.

Whisky. I already liked Whisky before travelling Scotland, but man, after those three weeks I am _so_ into Whisky. For me the best Whisky this year was the Lagavulin, 16 year old, Single Malt from the beautiful Isle of Islay. During our Scotland trip we have been to different distilleries, Lagavulin and Laphroaig amongst others.

The three weeks are filled with nice memories and the photos above only give a small glimpse on this time.

Chaos macht Schule

Chaos macht Schule is a project by the german Chaos Computer Club, in which hackers with a technical credibility go into schools to hold presentations or conduct workshops.

This year the local Chaos Computer Club group has been invited two times to a school to give talks on privacy awareness and participate in a parents evening on the topic of data privacy related topics. Matou, Nico and I went there for the first event. We gave a presentation to two groups of about 50 pupils each, and one talk at the parents evening. Later this year, matou and I went back to the school to do the same event again. I am very satisfied with the whole event and before describing too much here: In February, straight after we were finished, we set up a voice recorder to capture our enthusiasm and remindings while driving home through the nightly, heavy snowfall.

We published this recording as part of the /dev/radio unstable program, which we have started a while ago. Unplanned, experimental podcasts, with completely different lengths and questionable quality, explicitly marked as unstable.

The events had a heavy focus on (data) privacy and we were (specifically) invited to shine some light on this topic. However, I would like to get more into inspiring people to do creative stuff, opposed to describing issues and problems. Just some ideas: The Little Bits project is a great project, which makes it easily possible to build interesting stuff without having to get too technical. Also, if someone would have showed me the endless possibilities of free operating systems when I was 14, I would probably have locked myself in forever. The fact that you can build your complete own system, replace each part of it, modify anything, would have just blown me away. The whole Creative Coding movement with projects like (fluxus) where you build a music visualization just-in-time, Context Free as an easy way to create amazing art, 3D printers and of course Arduinos.

About Me

I am a 32 year old techno-creative enthusiast who lives and works in Berlin. In a previous life I studied computer science (more specifically Media Informatics) at the Ulm University in Germany.

I care about exploring ideas and developing new things. I like creating great stuff that I am passionate about.
