First day of WWDC passed away, it was quite new experience for me. I omitted all WWDC news, there are tons of that, Most of them you probably know (iPhone4, Safari 5, iOS4 etc.) and that you don’t know are under NDA so I cannot write about that.

Thoughts with C&W

Monday, June 7th, 2010

Sitting at the Hotel, jet lag woke me up, so I start reading articles from my “to be read” pile.

  1. Facebook’s Culture Problem May Be Fatal – The Conversation -> Bruce Nussbaum wrote article about problem with Facebook privacy, I totally agree with him, and currently I think about quiting Facebook. Worth to read how public is our private profile.
  2. Corpus Adamicum – BDD-style Testing For IPhone Projects -> Are you writing iPhone app, and you want to wrtite test for yours application, I know that it is hard, but maybe Cedar will help you with that. Here is iPhone project which is fully test driven with Cedar. Adam Milligan shows how he manage to do this by following some rules. Must read for iPhone developers. I have to look more deeply into Cedar and iPhone app unit tests as well.
  3. Realtime search for Hadoop – scalable log data management with hadoop part 3 -> Nice article about Lucene(finally they moved to Solr to get sharding for free) and Hadoop integration for large 30TB amount of log files storing and fast (2-3 seconds) quering. I found “reducing memory requirements” part really interesting, it will be helpful in future projects.
  4. Suspending Judgement -> very inspiring article about false judgements, how to avoid them, how this judgement influence our lives. Must read article.

Why C&W? It is easy. California has great Cheese & Wine.

about me

My name is Sebastian Pietrowski. I've finished Warsaw University as Master degree. I started my journey with Java 1.1 with Thread and JDBC programing in 1998 as I worked for merlin.pl. In 1999 I've passed Java Programer Certificate for Java 1.2, and was solution architect of merlin.pl infrastructure when we was moving from pl/sql to J2EE. It was great performance optimization with 10 times more req/sec than in requirements and 85 times faster as original solution.

Currently I work as Expert Software Development Java at F.Hoffmann-La Roche. The company was founded in 1896 and today, Roche employs over 80.000 people. After work I'm involved in activities related to Scala/Lift, Ruby/Rails/Merb, Python/Django. This is because I try to be pragmatic also I'm focused on application performance and tuning with success in my daily work.

My Yoda's motto: Do, or do not. There is no try.
