Parking information/entrance information
Yonego has their own parking lot and bicycle parking behind their building. This site is available via an entrance from the Prinsenkade.
Unfortunately, there is limited parking space. If there is no parking space anymore, parking your car into the parking garage: ‘De Barones’ or ‘De Prins’ is recommended.
At your arrival you can ring the doorbell at house number 5G and go to the reception at the third floor. There you will find us.

Talk: Object Invariants, Immutability & You: Making Objects Do Your Bidding
Code tells a story, but is it the actual story the original author wanted to tell? A lot of time the original story gets lost, as new functionality gets bolted on, or key parts are extracted, leaving behind an incomplete picture. These repurposed objects might pass all the unit tests but have no actual meaning in the context of the original story.
We will take a look at how we can more easily communicate the purpose of code to future developers, by introducing contracts and immutability, and using explicit context bound language, to give meaning to the code and keep the story whole.
Speaker: Jeroen van der Gulik
