Marathon
Running my first full marathon
Last Sunday I completed my first full marathon, covering a distance of 42KM in and around Amsterdam. An idea that started in a bar with some beers and concluded with a finish in the Olympic Stadium. What a journey, what an experience, well worthy of a blog post.
I see dead people
Augmenting old photos in virtual reality
Imagine seeing your dead family members - not just on a picture, but lifelike and in three dimensions! You can almost touch them. It hits you differently, I can assure you. I'm still in awe: I just saw my dead grandfather, lifelike and for the first time ever in three dimensions! This may be Apple Vision Pro's killer feature, if you allow me the pun, please hear me out.
Developing a native iOS app
Making a cycling and running tracker
As a little side-project, squeezed between my normal work, I have been working on something of personal interest: a native workout tracking app for iOS. I wanted to make my smartwatch obsolete, instead using my phone to track workouts. How hard could it be to gather detailed sensor data using native Swift APIs?
