SD West – last day

Friday, March 14th, 2008

The last day was little bit dull. I think because it was last day and mans was going to flights , and it was sad. First speech was “Aspect-Oriented Design and Programing in Ruby” by Dean Wampler. He creates and manages AOP ruby project called Aquarium. He shown a lot of code, and by examples of rails he shown how aspect oriented design may help even when language has enough power (meta programing). It was really interesting very advanced topic and I’m going to investigate it.

Next talk was hard to choose, in last minute as continuous working group member I decided to see “Automating Builds: Brining Quality and Testing Forward” by Zach Nies. He is co-author of very nice blog about agile methodology “theagileblog”. It was a quite good presentation.

And Ladies and Gentlemans the best of the best speech was a lunch keynote “Dances with Robots” by James McLurkin. What can I say, it was stunning presentation. Everyone after that presentation goes to Lego store to buy some Mind-Storms. James personality is so cute and pleasant. I can not describe this session even in 1 percent, so I suggest you go to James homepage and read it and if you had opportunity to see him life go there, you will be applaud. BTW the first question was “how can I start to do something like this?”.

I’m java developer so next two session was java path. First of them was “Memory Leaks in Java Applications: Different Tools for Different Types of Leaks” by Greg Sporar. With help of sample application Greg shown us different types of leaks and how to hunt them easy and quickly, good technical presentation.

The last one “Programing in Hadoop” by Owen O’Malley. He described as map-reduce algorithm, which is implemented in hadoop. He shown us some bad example when not properly used map-reduce can kill network or machines. The numbers Owen was talking about was impressive over 1000 nodes compute over 100TB data.

After that we went to see Golden Gate and by the way we go to Google campus, Roche in Paulo Alto. The roche division is next to XEROX and some others well known for IT guys companies. And of course we can’t finished in other way as going to Apple Computer Inc headquarter One Infinite Loop street in Cupertino.

See You

SD West – the begining

Friday, March 7th, 2008

Due to our time, I will be describing SD West from the past perspective. California is great place to be, we sow so much vineries and of course Golden Gate. Than we move to sierra nevada near Lake Tahoe. One fact : The State of California (the size is similar to Poland) can be supplied for 5 years by the water drying from this lake. Than we were riding through mountains to Santa Clara. We saw nice views, so much snow. Great journey.

Next I bought my dreamed MacBook Pro machine. And so far I’m very glad of it. So this post is from my new machine.

So the first day on SD West was short, we’ve see some of the Expo and a keynote “Is Agile Really Working for You?” It was some sort of nice speech. Than we are in Intel museum, and what’s funny that all places are prepared to came with kids.

One thing to mention is Monterey Aquarium, the must see from my perspective.

Ok the next day was intensive one. First of all I went for “Clean Code:Ruby” and it was good choice. Robert Martin is great speaker. He was full of energy, and he made great speech.

Next I go for Johanna Rothman “Guerilla Agile: Stop Playing Schedule Games”. The Johanna’s experience was huge, She talks about many different situation, and what to do. So many examples, so much knowledge, hopefully there was a rest due to lunch meeting.

And finally the last presentation Jeremy Manson and Paul Tyma about “Java Performance Myths”. They pointed out some myths about performance. This was good technical presentation.

So far so good, there are two more days to describe in air view. And than I will write about few of this session in details.

See you.

Blog reloaded ;)

Tuesday, February 26th, 2008

This blog was a try out. It’s goals were:

  • improve my English (still poor ;/ )
  • try to become more open
  • share knowledge

Now it’s time to reactivate. In this days I’m involved in startup “natrasie” (in polish) and some other activities, so my blog importance was low. It’s time to challenge with time and my weakness.

First at all, I will post more regularly, secondly I will introduce cyclical articles with more code. The friend of mine Gotomi create CSS for my articles.

It’s time the second phase of experiment begin.

Next item on my agenda is Google Android SDK

See You Soon

New Home

Thanks to Gotomi I’ve got new home, but it is a beginning of long way. Keep tracking, I’m coming

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.
