I always wanted to attend a Maker Faire whenever I heard about it. A fair for people who build and create things with their own minds and hands; a fair for children to show them how accessible technology is and how easy it is to get started to build their own things; a fair for those who do instead of just keep talking. However, until now I never had the time or was just too far away to attend. Last weekend, April 16 and 17, the Maker Faire came to Vienna, which meant that I finally had this opportunity.
The One Love Machine Band
There is not enough space here to count all the great and cool things that were shown at the Maker Faire Vienna 2016, but we saw a machine that was automatically baking typical Austrian pancakes “Palatschinken“, another one that created typical Austrian “Spritzer” – a mixture of sparkling water and wine. A technical college who showcased their pupils’ cool projects was not missed. Also, the racing team and the space team of the Vienna University of Technology were there. Vienna’s hacker spaces had their own booths and many many more people who demonstrated their skills. Pity, it would not be feasible to name them all. High rooms, old wooden floors, big wooden bars across the room and huge pillars impregnated a special atmosphere to the event.
Since there were so many things to see and I had to prepare my own talk “Smart Home – from Maker to Market”, I can’t really say anything about any of the talks there. They are all available on Vimeo, so I guess it’s worth watching them if you are interested and couldn’t attend the sessions.
I gave a talk that was not so much about a smart home, but what would happen if we connected many smart homes, which benefits we could have, the challenges as well as the high level architecture. Well, I would have liked to talk about all of these things in more detail, but I was limited to 30 minutes. Watch the video [german] and if you have questions, don’t hesitate to contact me.
I am excited to see this event outgrowing its current location and hopefully the Maker Faire Vienna 2017 comes back with even more makers, more cool projects and more great people.
The Hadoop Summit is a tech-conference hosted by Hortonworks, being one of the biggest Apache Hadoop distributors, and Yahoo, being the company in which Hadoop was born. Software developers, consultants, business owners, administrators, that have a mutual interest in Hadoop and the technologies of its ecosystem, all gathered in Dublin – this year’s Hadoop Summit of Europe took place in Ireland. The Hadoop Summit 2016 Dublin had some great keynotes, plenty of time to network and a lot of exciting talks about bleeding edge technology, its use cases and success stories. Also it was a great opportunity for companies working with Hadoop to present themselves and for the visitors to get to know them.
Keynote: “Data is Beautiful”
The organisation of the conference was great. 1300 people participated, but it never felt crowded, nor were there any (big) waiting lines to enter the speaker rooms or at the lunch buffet.
My Favorite Talks
This is a list of my favorite talks in a chronological order with their videos embedded. To be honest, this list is basically almost all of the talks that I saw in person and probably I missed even more great talks, that were given in parallel. Fortunately, we can see all of them on the official Hadoop Summit 2016 Dublin Youtube channel.
- SQL streaming: This talk gave a really nice overview of the development of an SQL streaming solution with all its technical challenges and how they were addressed. Also simple technical use cases were discussed and compared to traditional SQL, where each query terminates, whereas streaming SQL queries never terminate.
- Hadoop at LinkedIn: Here we got valuable insights into the Hadoop landscape of LinkedIn, as well as job monitoring and automated health checks. A job monitoring tool, Dr. Elephant, developed by LinkedIn was open sourced only a few days before the start of the Summit.
- Containerization at Spotify: This talk was about how Spotify uses docker containers and the tools involved in their automated IT landscape. The best part starts at 39:30, where it is revealed, that Spotify overcomes security challenges by not implementing internal security measurements at all. According to the speaker everyone can access everyones data. If life could always be as simple as that 🙂
- Apache Zeppelin + Apache Livy: Apache Zeppelin already is a great tool for interactive data analysis, exploration or even doing ETL tasks using Apache Pig, querying data using Apache Hive, as well as executing Python, R or bash scripts. Apache Livy helps data scientists work together in one notebook on a secure cluster. What I like a lot about this talk is, that the speakers nicely explain the authentication mechanism involved.
- Apache Phoenix: Apache Phoenix is a SQL query engine on top of Apache HBase and much more. This talk was basically a view on the capabilities and features of Apache Phoenix. Great stuff – nothing more to add. Watch the video!
10 Years of Hadoop Party
In the night of day one, the Guinness storehouse was utilized as a huge burger-beer-and-big-data networking event. As you can imagine there was good food, Guinness, great music by Irish bands on several floors and of course most importantly the same cool people attending the conference.

My first Hadoop Summit attendance was a great experience in all its particulars. I got great contacts, gained lots of knowledge and had lots of fun at the same time. Hopefully, I will be able to attend the next Hadoop Summit 2017 in Munich.
