Need your input: Failing big data projects - experiences from the wild # A few weeks ago my talk on “How to fail your big data project quick and rapidly” was accepted at O’Reily Strata conference in London. The basic intention of this talk is to share some anti-patterns, embarrassing failure modes and “please don’t do this at home” kind of advice with those entering the buzzwordy space of big data. ...
Note to self: Clojure with Vim and Maven # Steps to get a somewhat working Clojure environment with vim: Install the current vimclojure plugin. Get and install a nailgun client. Add vimclojure to your clojure project pom.xml. Start the nailgun server from within your maven project with mvn clojure:nailgun with the maven clojure plugin.

Preparation done - clock is ticking # The clock is ticking - only one more weekend to go before Berlin Buzzwords opens its doors for the main conference (check out the Wiki for the Sunday evening Barcamp and the Sunday Movie Hackday). Looking forward to an amazing week with awesome speakers and great attendees. One word of warning before: Given all the buzz around that conference as of now until mid-next week I won’t take any major decisions, most likely I won’t be able to follow through with any additional organisation, probably I won’t remember everyone I meet on-site. ...

Teddy in Zürich # A few beautiful sunny though windy days in Zurich late April: View from the path between Ütliberg and Adliswil/Felsenegg: Strolling through the city and sitting next to Zürichsee enjoying the sun afterwards: A boat trip to Rapperswil - started cold and cloudy, finished warm and sunny:
Teddy in Poznan # Some images taken in Poznan after GeeCon - big Thanks! to Dawid for giving advise on where to go for sightseeing, exhibitions and going-out. The tour started close to river Warta - it being a sunny day it seemed like a perfect fit to just walk through the city, starting along the river headed towards the cathedral: After that Poznan Citadel was a great place to spend lunch time - sitting somewhere green and shady: ...
GeeCon - Testing hell and how to fix it # The last regular talk I went to was on testing hell at Atlassian – in particular the JIRA project. What happened to JIRA might actually be known to developers who have to deal with huge legacy projects that predate the junit and dependency injection era: Over time their test base grew into a monster that was hard to maintain and didn’t help at all with making developers confident on checkin time that they would not break anything. ...
GeeCon - Solr at Allegro # One particularly interesting to me was on Allegro’s (polish Ebay) Solr usage. In terms of numbers: They have 20Mio offers in Poland, another 10Mio active offers in partnering countries. In addition in their index there are 50Mio inactive offers in Poland and 40 Mio closed offers outside that country. They serve 8Mio updates a day, that is 100 updates a second. Those are related to start/end of bidding phase, buy now actions, cancelled bids, bids themselves. ...
