Berlin Buzzwords 2010 - Scalability conference June 7th/ 8th in Berlin

2010-05-14 15:48
The Berlin Buzzwords schedule was published a few days ago. There are tracks specific to the three tags search, store and scale. We have a fantastic mixture of developers and users of open source software projects that make scaling data processing today possible.

There is Steve Loughran, Aaron Kimball and Stefan Groschupf from the Apache Hadoop community. We have Grant Ingersoll, Robert Muir and the "Generics Policeman" Uwe Schindler from the Lucene community.

For those interested in NoSQL databases there is Mathias Stearn from MongoDB, Jan Lehnardt from CouchDB and Eric Evans, the guy who coined the term NoSQL one year ago.

The schedule has been published online. Visit the webpage and register for the conference - looking forward to seeing you in Berlin this summer!

Regular tickets are available online. In addition we offer student tickets: If you have a valid student ID, you are eligible for one of these tickets. Each costs 100,- Euro. We also have a special group ticket available: If you buy four tickets or more you are eligible for a discount of 25%, when purchasing 10 tickets or more the discount is 50%. Learn more at http://berlinbuzzwords.de/content/tickets

One day before the conference we are having a Berlin Buzzwords Barcamp in town. In addition, directly after the conference, Cloudera will be hosting Apache Hadoop trainings - registration is separate from Berlin Buzzwords.

So just in case you need a good excuse for a long term trip to Berlin: You can spend the weekend in town, attend the Barcamp on Sunday evening, visit Berlin Buzzwords on Monday and Tuesday. The rest of the week could be used to take part in Apache Hadoop trainings. Finally you have one weekend left for a city tour.

Thanks to Jan Lehnardt, Simon Willnauer and newthinking communications for co-organising the event.

Berlin Buzzwords - End of CfP drawing closer

One week to go for submitting a talk on your favourite NoSQL topic, your favourite search application or your most interesting data analysis task: The call for presentations for Berlin Buzzwords ends on April 17th, that is Sunday next week.

Shortly after the last talk was submitted we will start announcing speakers - final list of speakers is to be expected by the start of May, final schedule will be published shortly after that.

Berlin Buzzwords - Early bird registration

2010-04-10 15:02
I would like to invite everyone interested in data storage, analysis and search to join us for two days on June 7/8th in Berlin for Berlin Buzzwords - an in-depth, technical, developer-focused conference located in the heart of Europe. Presentations will range from beginner friendly introductions on the hot data analysis topics up to in-depth technical presentations of scalable architectures.

Our intention is to bring together users and developers of data storage, analysis and search projects. Meet members of the development team working on projects you use. Get in touch with other developers you may know only from mailing list discussions. Exchange ideas with those using your software and get their feedback while having a drink in one of Berlin's many bars.

Early bird registration has been extended until April 17th - so don't wait too long.

If you would like to submit a talk yourself: Conference submission is open for little more than one week. More details are available online in the call for presentations:

Looking forward to meeting you in the beautiful, vibrant city of Berlin this summer for a conference packed with high profile speakers, awesome talks and lots of interesting discussions.

Seminar on scaling learning at DIMA TU Berlin

2010-03-17 21:10
Last Thursday the seminar on scaling learning problems took place at DIMA at TU Berlin. We had five students give talks.

The talks started with an introduction to map reduce. Oleg Mayevskiy first explained the basic concept, than gave an overview of the parallelization architecture and finally showed how jobs can be formulated as map reduce jobs.

His paper as well as his slides are available online.

Second was Daniel Georg - he was working on the rather broad topic of NoSQL databases. Being too fuzzy to be covered in one 20min talk, Daniel focussed on distributed solutions - namely Bigtable/HBase and Yahoo! PNUTS.

Daniel's paper as well as the slides are available online as well.

Third was Dirk Dieter Flamming on duplicate detection. He concentrated on algorithms for near duplicate detection needed when building information retrieval systems that work with real world documents: The web is full of copies, mirrors, near duplicates and documents made of partial copies. The important task is to identify near duplicates to not only reduce the data store but to potentially be able to track original authorship over time.

Again, paper and slides are available online.

After a short break, Qiuyan Xu presented ways to learn ranking functions from explicit as well as implicit user feedback. Any interaction with search engines provides valuable feedback about the quality of the current ranking function. Watching users - and learning from their clicks - can help to improve future ranking functions.

A very detailedpaper as well as slides are available for download.

Last talk was be Robert Kubiak on topic detection and tracking. The talk presented methods for identifying and tracking upcoming topics e.g. in news streams or blog postings. Given the amount of new information published digitally each day, these systems can help following interesting news topics or by sending notifications on new, upcoming topics.

Paper and slides are available online.

If you are a student in Berlin interested in scalable machine learning: The next course IMPRO2 has been setup. As last year the goal is to not only improve your skills in writing code but also to interact with the community and if appropriate to contribute back the work created during the course.

Early bird registration for Berlin Buzzwords on June 7th/8th open

2010-03-09 18:34
Silently registration was opened in the past days for Berlin Buzzwords - a conference on scaling search, data processing and storage taking place on June 7th/8th in Berlin/ Germany. First 100 tickets will be sold for 250 Euros + tax. Registration is possible at later dates as well, however expect prizes to rise shortly before the conference starts.

If you clicked on it earlier this week and were wondering what those strange German terms were all about: We have put online an English version as well, so language shouldn't be much of a problem anymore.

To avoid any confusion: Conference talks will be in English - no German language skills needed for that. It is perfectly well possible to get around in Berlin w/o speaking German, however knowing a few words as always will make it easier to make friends with people in shops and hotels ;)
