Melbourne-Man and the meat pie

I went on a trip to Ghent, Belgium this week, to attend a conference at the Artevelde Hogeschool. I had been invited to give a speech and to offer a workshop on H5P. The journey was great, but it felt so weird, that I’d just like to share my experience with you. There was nothing that was really extraordinary — sorry if you expect that — but in total the small bits and pieces formed a worthwhile journey.

Monday (or Sunday)

Actually, everything started last weekend in Tromsø, Norway. That’s where I live. The sky decided that it was time again to cover the city in some new snow. If I say „some“, then I mean quite a lot for someone who spent most of his life more than 15 degrees of latitude further south. In these conditions, public transportation in Germany would have come to an immediate halt, but the Nordmenn didn’t care at all. My plane departed right on time before noon on Monday.Suburban road covered in much snow

At the airport in Oslo I had to wait for my connecting flight, and I decided to grab something to eat. I don’t know what went wrong, but the payment terminal at the store didn’t accept my VISA card. So, I tryed an ATM. It wanted my PIN code, which I had never used before and still don’t know. „Well, I still have my German debit card“, I thought to myself. Unfortunately, it seems that six weeks without using it can be enough to forget the PIN code and to lose your muscle memory. Well, let’s call the bank, get three new attempts, and fail three more times. Keep your „You could have used a password manager!“ to yourself :-P

Oh, oh. I was smart enough to have taken my last 26 € in cash with me, but what if in Belgium I needed my PIN code for VISA transactions? Long story short: Thomas and Dries who I was about to meet in Belgium established PayPal2Cash, and Dries met me at the train station in Ghent to bring me the money. Thanks again! The end? Not quite. Dries had forgotten to take his card from the ATM and the machine had sucked it up …

It was close to 22:00, and I decided that it was time to finally eat something, and the first place that I found on my way to the hotel was a kebab joint. It’s run by a very nice fellow. We chatted a little bit about what I was doing in Ghent, and he tried to buoy me up — although I have done it dozens of times, I still don’t feel comfortable giving speeches. He said, the most important thing was to be happy, and he suggested I should visit him again on Wednesday before I went back home. I did, and I will not forget to tell you more about that encounter later.

The day was not quite over, but unscrambling some reservation issue at the hotel and putting one more hour into the preparation of my speech are hardly worth mentioning.


On Tuesday morning, I woke up by the sound of my alarm clock. That’s rare. I am usually awake before, so I must have slept like a stone. As a result, I decided to get some more minutes for snoozing. I could still hurry a little bit to get to the conference on time. Bad idea. Performing my morning routine in the bathroom in 4th gear led to me losing one of my contact lenses. On the sink? On the floor? I couldn’t find it and still don’t know where it has ended up. And, of course, I didn’t bring spare ones.

“What are your choices when someone puts a gun to your head? — What are you talking about? You do what they say or they shoot you. — WRONG. You take the gun, or you pull out a bigger one. Or, you call their bluff. Or, you do any one of a hundred and forty six other things.” (Suits)

Since I didn’t have time to get new lenses, I decided that one of these a hundred and forty six other things would be to remain short sighted and to turn it to my advantage. My speech had a section about accessibility of software anyway, and now I didn’t even have to play being visually impaired when demonstrating it. The speech went well. So I was told at least. I was not content with my performance, but I don’t think I have ever been after giving a talk. It’s not my thing. I prefer what followed next.

I joined Thomas, Dries, Frederic, and some others to the learning café where the congress attendees could hang out and learn about some of the technology that Artevelde Hogeschool uses: Panopto (a video platform for education), Canvas (a learning management system) and H5P. Some people approached me with questions about H5P, we discussed some aspects, and I demonstrated some features. Very nice!Learning café

After the congress, the guys showed by a little bit of Ghent and told me about some of the town’s history. For example, Ghent revolted against the regime of the Holy Roman Emperor and Spanish king Charles V. — you know, the guy whose chief metallurgist was Juan Sánchez Villa-Lobos Ramírez!? At least that’s the knowledge that I could chip in ;-)

Afterwards, we went to a restaurant, and that’s where we met him: Melbourne-Man! There was this Asian looking guy who at some point started to chat with us about how great the Belgian lifestyle is — he meant good food and affordable beer. He obviously missed it in Sweden where he lives and works. And he laughed a lot whicht might have been related to the beer. But, more importantly, it turned out that he was from Melbourne, Australia! That’s where the next H5P conference will take place. We got many hints about what we shouldn’t do (road trips are supposed to be boring) and what we should do when we’re down under (kangaroos, of course). And for some reason he was very fond of meat pie which we should definitely try. Melbourne-Man, it was a pleasure to meet you!


On Wednesday, I went to a different location of Artevelde Hogeschool closer to the city center. That’s where the H5P workshop took place. I knew beforehand that there would be some people without prior knowledge of H5P and some who had been using it for quite some time. I didn’t want anyone to be bored, so I prepared some practical environment where newcomers could explore the basics and the experienced guys could fiddle around with several features and content types that have not yet been released. Of course, I also answered some questions and demonstrated some things, too. I liked this workshop much better than the speech.

Afterwards, I still had a little time to explore the city of Ghent on my own. It’s really beautiful. With all the cobblestone and the tram, it reminded me a little bit of Braunschweig, Germany where I lived quite a while, but the inner city of Ghent felt bigger, and it had canals running here and there. I wouldn’t have minded to stay longer.


Oh, but before returning to Norway, I had to visit the kebab place again. The guy behind the counter recognized me instantly and asked me how the speech had been. Another guy was there, who was introduced as a friend of his. And then they quickly turned the chat to watching porn and „sword-fighting“ and I don’t want to explicate that further. WTF?! They might have played me for a sucker, I don’t know. I grabbed a coke, said goodbye, and left for the train station :-)

The train ride and the flights went well, and I was looking forward to getting some sleep. Unfortunately, all the gates at the airport in Tromsø were blocked by other planes and we had to wait some time until one was cleared. Not very long, but long enough for missing the last bus to the city center that departs briefly after midnight. And what do you do if you’re me and you don’t want to wait for a cab? You decide to walk home :-) That meant tramping up a hill through snow for over an hour, but it was worth it: Close to my place, I met an adorable Norwegian forest cat who seemed to be glad to have found someone she could chase and play with in the middle of the night.

All’s well that ends well.

mooin war auf der MetaNook in Lübeck

Am 10. November waren @anjalorenz und ich auf der MetaNook in Lübeck unterwegs. Die MetaNook ist bereits seit 2011 eine — ich würde sagen — Abendveranstaltung für Technik- und Bastelbegeisterte. Ihr findet dort Vorträge zu entsprechenden Themen, diverse Stände mit Nerdkrams und Mate-Ausschank. Ausgerichtet wird die MetaNook von der MetaMeute und dem Chaotikum.

Der Herr am Empfangstresen verstand zwar nicht so viel Spaß und konnte mit unserem freundlichen „Hallo, wir sind Anja und Olli, und wir wollen mit euch über Bildung sprechen!“ nicht so viel anfangen, aber unseren Vortragsraum haben wir dann doch gefunden. Da haben wir dann vor einem Massenpublikum von fünf Zuschauern (tatsächlich nur Männer) mooin vorgestellt. Schaubilder und Aufzeichnung findet ihr hier.

Die Schaubilder

Die Schaubilder hatten wir thematisch in vier Blöcke gruppiert, die sich die Anwesenden gezielt hätten auswählen können: Über Schaubild 4 können die Unterthemen gezielt angesprungen werden, und per Klick in die linke obere Ecke auf den anderen Schaubildern gelangt man wieder zurück. So viel Freiheit schien aber ungewohnt zu sein ;-) Dank der betitelbaren Schaubildleiste von H5P konnten wir aber auch so zügig zu einzelnen Schaubildern springen.

Die Aufzeichnung

Die Aufzeichnung des Vortrags lief ganz simpel mit Camcorder und zwei an Smartphones geklemmte Lavaliermikros. Die Kamera stand leider in weiter Ferne und die Beleuchtung war mau, aber dafür finde ich den Ton wirklich gut.

Wer rastet, der rostet

Badge Google Developer Challenge Scholarship RecipientSo ein bisschen Rost gibt ja Charakter, aber irgendwann wird alles spröde. Da Google mir dankenswerterweise  wieder ein Stipendium bei Udacity spendiert, mache ich mich ab heute an das Nanodegree-Programm Mobile Web Specialist.

Die Anforderungen erfülle ich zwar nicht, denn über 1-2 Jahre (Vollzeit-)Erfahrung in der Frontend-Entwicklung in HTML, CSS, and JavaScript verfüge ich nicht — aber die Herausforderung nehme ich an!

Braucht ihr Unterstützung? Gebt her eure Daten!

Arbeitet ihr mit Daten und braucht kostenlose Arbeitskraft? Dann solltet ihr weiterlesen!

Vor nicht ganz drei Wochen habe ich bei Udacity mit dem Nanodegree-Programm zum „Machine Learning Engineer“ begonnen. Gestern Abend zeigte mir die App dann bereits das Erreichen der 95-Prozent-Marke an. Tatsächlich muss ich nur noch ein Projekt bearbeiten, das ein Thema abschließt. Danach steht schon das finale Projekt an.

Fortschrittsbalken mit 95 %Das tolle an diesem Abschlussprojekt: Ich kann mir Problem und Fragestellung selbst wählen und dann bearbeiten. Das wird das Analysieren passender Daten umfassen, um daraufhin Software zu schreiben, mit deren Hilfe Erkenntnisse gewonnen werden können. Außerdem müssen die Gedankengänge dahinter samt der Ergebnisse in einem Bericht festgehalten werden. Der soll rund 10-15 Seiten umfassen. Ist also im Prinzip so etwas wie eine Seminararbeit an einer Hochschule. Damit man sich vorstellen kann, wie so etwas aussieht, stellt Udacity auch Beispiele bereit.

Ich habe schon ein paar Ideen, was ich machen könnte. Die haben den ein oder anderen Pferdefuß. Manchmal fehlt mir das Wissen zu einem bestimmten Fachgebiet, aus dem die Daten kommen. Manchmal habe ich ethische Bedenken, weil die Datensätze auch in anonymisierter Form mit ein bisschen Aufwand Rückschlüsse auf Einzelpersonen zuließen. Das ist durchaus relevant, weil ich natürlich alles offen erarbeiten und bereitstellen möchte.

Ich hätte da ein Angebot…

Falls ihr mit Daten hantiert und vielleicht gerade nicht die Zeit oder Kenntnisse habt, mit denen weiter zu arbeiten, hätte ich ein Angebot für euch. Ich könnte euch kostenlose Arbeitskraft dafür schenken. Bedingung wäre halt, dass ich neben meinem Bericht und meinem Quelltext auch die Daten offen zur Verfügung stellen dürfte. Das ermöglicht es anderen, meine Ergebnisse bei Bedarf nachzuvollziehen und zu überprüfen. Schließt diverse Dinge vermutlich aus, aber das ist dann halt so.

Falls ihr mehr dazu wissen möchtet oder eine Idee habt, hinterlasst doch einfach einen Kommentar oder meldet euch direkt bei mir. Lasst mich aber nicht zu lange warten. Ich möchte bald loslegen :-D
