Reading Time: 2 minutes My daughter has been to the Montessori Toddler program (Hope Academy in Creve Coeur) for over a year, and I think I am becoming a Montessori dad. This is a bit abstract, but I like to list a few examples about the school and teachers, and show why they are great. This is the first

Reading Time: 2 minutes I changed my job this Jan. I started working for a coal company as mobile app developer.

I don’t like the default keyboard on iPad because it takes too much of the screen, and in some cases covers up the input field. 1) From iphonedevsdk: What is proper way to do UITextField text change call back?

Reading Time: < 1 minute I was involved into a car accident in the past weekend. We are all fine, so as the other party. The main thing is both cars got some damage. It’s funny when I drove the broken car on the road, I got quite a few “look back” from other drivers. And yesterday, at McDonald parking

Reading Time: 2 minutes Have not done this for a while. I have changed job again, and in the new year started a developer position very close to home, doing mobile (iOS, iPhone, iPad) development.
