I'm a software developer with 20 years’ experience who's had the chance to work across a bunch of different projects and platforms. Over the years, I've dipped my toes in everything from game development and graphics rendering to mobile and desktop app development.

Recent Work: My recent years have been dedicated to working with a US based company, focusing on macOS app development with Swift/SwiftUI and rendering engine enhancements. In addition, my freelance portfolio includes diverse projects such as backend development in Python, creating a custom VR rendering engine for Oculus Rift, and implementing a one-to-many video streaming platform as an iOS app and accompanying website.

Full work history available on my LinkedIn profile.

My opinion is that we are predictable and deterministic, but we choose to cling to the idea of us being more than that because we can't deal with the other option. The other option is quite simple, from what I see: we'll never manage to completely read, simulate and predict a complex system like our body, so in reality nobody will be able to predict what we'll do - and for me that's enough to feel comfortable. From what I see free will is defined by others as some kind of magic process through which our decisions are based on some random factor which is unpredictable. I'd say the randomness doesn't need to exist as long as the unpredictability holds.

I don't have any tests to prove this, but switching from a 64-bit kernel to a 32-bit one and forcing apps to run in 32-bit mode helps a lot with memory usage on OS X. You can use this app to switch apps to 32-bit: http://www.macupdate.com/app/mac/40405/sixtyfour

If you look at Windows 7 memory consumption with the same set of software you use in OS X, you'll notice memory usage is 1/2 or 1/3 on Windows compared to OS X. Maybe someone knows why that is?
