Large Scalability - Papers and implementations # In recent years the Googles and Amazons on this world have released papers on how to scale computing and processing to terrabytes of data. These publications have led to the implementation of various open source projects that benefit from that knowledge. However mapping the various open source projects to the original papers and assigning tasks that these projects solve is not always easy.

Scrum Table Berlin # Last week I attended the scrum table Berlin. This time around Phillippe gave a presentation on “backlog colours”, that is types of work items tracked in the backlog.
The easiest type to track are features - that is items that generate revenue and are on the wishlist of the customer. Second type of items he sees are infrastructure items - that is, things needed to implement several features but invisible to the customer.

Open Street Map @ FSFE meetup # At the last meeting of the local FSFE group here in Berlin Sabine Stengel from cartogis gave a presentation on Open Street Map. But instead of focussing on the technical side she described the legal issues and showed the broad variety of commercial projects that are possible with this type of mapping information.
It was interesting to learn of how detailed and high quality the information provided by volunteers really is.

Keeping changesets small # One trick of successful and efficient software development is tracking changes in the sources in source code management systems, be it centralized systems like svn or perforce or decentralized systems like git or mercurial. I started working with svn while working on my Diploma thesis project in 2003, continued to use this systems while researcher at HU Berlin. Today I am using svn at work as well as for Apache projects and have come to like git for personal sandboxes.

Ken Schwaber in Berlin XBerg # Last week I attended a discussion meetup with Ken Schwaber in Berlin/ Kreuzberg. The event was scheduled pretty shortly
still quite a few developers and project managers from various companies in Berlin showed up.
Ken started with a brief summary of the history of Scrum: Before there was such a thing as an IT industry programming actually was a lot of fun. But somehow the creative job was turned into something people tend to suffer from pretty quickly as people tried to apply principles from manufacturing industries to software “production”.

Open Source Development is good for you # GSoC (Google summer of code) - one of the open source programs of Google - has started again in 2009. Students come to work for open source projects during the summer and on success are paid by Google a fair amount of money.
This program is an ideal oportunity for students to get into open source projects: You get a mentor, you have pre-defined task to work on with a goal you set yourself.

Tomcat Tuesday talk # Since several months at neofonie we have a talk given by external or internal developers on various subjects each Tuesday. Usually these presentations are a nice way to get an overview of new emerging technologies, to get an overview of current conference topics or to gain insight into interesting internal projects.
This week we had Apache Tomcat Committer and PMC Peter Rossbach here at neofonie to talk about the Tomcat architecture and Tomcat clustering solutions.

Back from Zürich # I spend the last five days in Zurich. I wanted to visit the city again - and still owed one of my friends there a visit. I am really happy the weather was quite nice over the weekend. That way I could spend quite some time in town (got another one of those puzzles) and go for a hike on the Ütli mountain: I took the steep way up that had quite a lot of stairs.
