Title: Chemnitzer Linuxtage
Location: Chemnitz
Link out: Click here
Start Date: 2010-03-13
End Date: 2010-03-14


Next week the Chemnither Linuxtage take place in - well - Chemnitz. It is the second largest Linux event after Linuxtag Berlin. However only obvious for speakers and exhibitors: It is one of those events that are known for its fantastic organisation. Nearly no problems, be it WiFi, admission to the exhibitors area, food or any help in general.

I will be at the event again. You can find me at the FSFE booth, telling people what the FSFE is all about and trying to convince them to become fellows (and yes, since last summer, I am a fellow myself and own one of those really cool green crypto cards).

Berlin Buzzwords - June 2010

2010-02-11 22:42
As announced at FOSDEM: Early June (currently scheduled for 7th/8th) a conference on the topics scalable search, storage and processing will take place in Kalkscheune/Berlin. The conference is co-organised by newthinking store, Jan Lehnardt, Simon Willnauer, Thilo Fromm, and Isabel Drost.

The focus will be on NoSQL databases like CouchDB, Jackrabbit, MongoDB, HBase. Search tracks will cover topics like Lucene, Solr, katta and others. Data munging tracks will focus mainly on Hadoop, MapReduce in general and distributed systems.

More information including the call for presentations will be made available online next week on a separate webpage. Early registration starts in March. Watch this blog for more information or follow @hadoopberlin.

FOSDEM 2010 - part 3

2010-02-10 21:02
Sunday started in Janson with Andrian Bowyer's talk on RepRap machines, that is devices that can be used as manufacturing devices and are able to replicate themselves. After that I went over to the Mono dev room to listen to Miguel de Icaza on Mono Edge. A great talk on the history of Mono, the way the community interacts with Microsoft, the C# language itself and special features only available in Mono.

After this talk we went over to Janson for Andrew Tanenbaum's talk on Minix. We knew quite a bit of the talk already from Froscon two years ago, however Andrew is an awesome speaker, so it's always fun to catch up on the news on Minix.

The scalability talk started with an introduction to Hadoop by myself and continued with a talk on the facebook infrastructure by David Recordon. According to feedback I got after the talk, laughing with Thilo helped quite a bit to get myself calm. Before the talk I received one very good recommendation of one of the audio guys: Imagine you are giving the talk to one of your best friends - and forget about the microphone. Though I had way more slides than minutes to talk, we had enough time for the Q&A session after the talk. I started the talk by learning more about the audience - however this time not by handing the microphone to those listening (room too large) - I just asked them "have you heard about Hadoop?" - half of the audience. Are you Hadoop users: one quarter maybe. How large are your clusters? - 10 to 100 nodes mostly. Have you heard of Zookeeper? - some, Hive - some more, Pig - a few, Lucene - a lot, Solr - a little less, Mahout - maybe 5, Mahout users: 1.

Turns out the Mahout user in the audience was Olivier: It's so nice to meet people you know are active on the mailing lists for real and have a chat with them. Hope to see you more often on the lists - and meet you face to face again.

I used the chance to announce the Berlin Buzzwords 2010, a two day event on search and scalability buzzwords like cloud computing, Hadoop, Lucene, NoSQL and more. It takes place on June 7th and 8th in the center of Berlin. Follow this blog for further information. Judging from the input I got after the announcement there is quite some need for such a conference in Europe.

The slides of my talk are soon to be available online.

After my talk I could stay in Janson: A talk on the Facebook infrastructure (not only the Hadoop side of things) followed. After that I met Lars George at the NoSQL dev room - unfortunately I did not manage to actually talk to Steven Noels, who organised the room.

The afternoon was reserved for Greg Kroah-Hartman on how to "Write and submit your first Linux Kernel Patch" - my personal conclusion: git is really awesome. I really, really need to find a few spare minutes to learn how to effectively use it.

In the evening we met with Pieter Hintjens for dinner - and to finalize an awesome weekend in Brussels and a great 10th anniversary FOSDEM. A huge Thank You to all volunteers and organisers of FOSDEM - you did a great job this year putting together an awesome schedule, you did a fantastic job making the now pretty huge event (with 306 talks and about 5000 hackers attending) run smoothly. Even the wireless was working from minute one. See you again at FOSDEM 2011.

FOSDEM 2010 - part 2

The event itself featured 306 talks - so pretty hard to choose what to watch on two days. This time, not only the main tracks were awesome, but also several dev rooms featured very interesting talks by well known FOSS developers.

Saturday started with a FOSDEM birthday dance done by all attendees. The first keynote speaker Brooks Davis explained his experiences promoting open source methods at a large company. After that Richard Clayton gave an amazing talk on the evil on the internet. He explained not only how phishing works on a technical level but also included an explanation of the economics behind these attacks, explained how the money flow from victims to attackers works.

On the afternoon Bernard Li gave an introduction to the cluster monitoring tool Ganglia. Directly after that Lindsay Holmwood gave an overview of the monitoring and notification tools flapjack and cucumber-nagios.

The evening was filled with the speakers dinner. Thanks for the organisers for providing that. We had a really nice evening together with some of the organisers, Andrew Tanenbaum and Elena Reshetova at our table.

FOSDEM 2010 - part 1

Four years ago I was working in Saarbrücken. From there it is a very short ride over to FOSDEM (little more than 300km). So I decided - hey, why not stay there for a weekend. I found a very nice Brussels bed and breakfast hotel called Rovignon - featuring not only comfortable rooms at reasonable prizes but also cats in the house.

Back then, I barely knew anyone at the conference. However the lineup of speakers including St Peter from XMPP and Georg Greve from FSFE was impressive.

As a result it became a loved tradition of Thilo and myself to drive over to Brussels, attend FOSDEM and watch great talks. Over time there were more and more familiar faces, e.g. at the FSFE booth, among the Debian people...

Last weekend I had an awesome time in Brussels at FOSDEM for the fourth time in a row. I am honoured to have been invited by the FOSDEM organisers for a main track talk on Hadoop in the scalability slot (in Janson...).

We arrived on Friday afternoon, however being awefully tired we unfortunately could not join the Friday evening beer event (though, as I am not drinking beer, I would probably have missed quite a bit of the fun).

FOSDEM 2010 - 10 years FOSDEM

2010-02-03 19:33
I'm going to FOSDEM, the Free and Open Source Software Developers' European Meeting

The final schedule of FOSDEM 2010 is up: Looks like bad news - 306 interesting talks within just one weekend. Lots of interesting talks in the main track including Greg Kroah-Hartman on "Write and Submit your first Linux kernel Patch", David Recordon from Facebook on "Scaling Facebook with OpenSource tools", Bernard Li on "Ganglia: 10 years of monitoring clusters and grids", Andrew Tanenbaum with his "MINIX 3: a Modular, Self-Healing POSIX-compatible Operating System" talk, Benoît Chesneau on "CouchDB! REST and Database!" and many, many more.

In addition there will be many interesting DevRooms, including one on NoSQL, one on Free Java, the Mono DevRoom featuring a talk by Miguel de Icaza...

Looks like a weekend packed with interesting talks and discussions. If you are going there and are interested in an ad-hoc Hadoop-Beer-drinking meetup, make sure to contact me before the event.

Hadoop at Heise c't

Interesting for those readers speaking German: Heise published an introductory article on Hadoop in its latest issue. Have fun reading.

Thanks to Simon for proof-reading and providing valuable input. Thanks to Thilo Fromm for the hadoop graphics (unfortunately none of them got published in its original form), the catchy title, proof-reading the text over and over again and for keeping me sane during several past and coming months.

If you want to know more on Apache Hadoop, come watch my FOSDEM Hadoop talk next weekend. If you want to join discussions on Apache Hadoop and Lucene, stay tuned for a conference in Berlin on these topics.
