Have apple introduced the iPhone 3GS they made an major switch in processor architecture, the want from armv6 to armv7.
Now that we have all update to Xcode 4 with iOS 5, Apple seems to be of the opinion that you can drop support of the armv6 architecture.
Well this isn’t always the case, especial for those device that can run iOS 4.*.
Luckily you solve this very easily, go to the the project build setting.
Many people have written about parsing JSON data on the iPhone, but why use JSON and not XML.
Well this has to do with overhead, JSON is smaller in it’s mark-up then XML thus it will take less traffic on the cellular network.
But there are some drawback in using JSON, since there is no real strict way of checking the model. Like DTD is for XML.

For those of you who are following/read my tweets you might have noticed me talk about Appsterdam.
Appsterdam is a community of app developer for all platforms, mostly iOS and Android.
Getting to getter and share experiences, ideas and a couple of drinks.
The main force behind this great idea, is Mike Lee (@bmf).
I’ve been active in other development communities when I was still developing in Delphi.
We would meetup once a year, at Borland in the Netherlands, to talk and eat.
Since I switch from Delphi to .NET I really started to miss the NLDelphi community, still have some friends form those days.
Looking for some thing new to do in the .NET community, I went to every meeting and conventions I could go to. But the community did no appeal to me at all.
Since switching to Object-C and the iOS platform, a choice I’ve yet to regret, it never crossed my mind to check out any communities. Being at an convention for developers there talk about a community for app developers.
Since I first heard about Appsterdam I really liking the idea, it could be a great way the share experiences and work out ideas. But It’s becoming more then just a get together.
There will be many things in store for the community, so I’ve you’re an app developer and live in Amsterdam (or nearby) come to one of our meetings. (follow @Appsterdamrs)
I’ve decided to move most of my open source code to GitHub.
This will allow easy bug fixing and extending by other developers.
Also GitHub is hip and new

As some of you might have noticed, the images weren’t working.
They all pointed to the old test domain I used to build this site, oeps.
I didn’t see it at first, because the images where in my browsers cache.
After some hardcore SQL queries everything looks like it should.
You have probably noticed the new site. I’ve been working on it for last couple of months. I hoop you like the new look. This new site has become more of a portfolio for my work and a blog for my thoughts.
