Distributed Systems Fundamentals Part 2: You Can Say That Again!

At Theorem, we approach problems by reasoning about them from first principles. To truly understand a problem and be confident about your solution, you must have a working understanding of the fundamental constructs and motivating logic behind what you’re doing. In this spirit, we’re releasing a blog series about the fundamentals of distributed systems. This post is the second of that series.

SwiftUI Implications

SwiftUI was warmly welcomed by the development community when it was announced at this year’s Apple Worldwide Developers Conference (WWDC). Given the wide variety of platforms and screen sizes, it makes sense for Apple to provide a standard UI abstraction layer which works across all of their devices. Creating, managing, and positioning each UI view, and their countless properties, to form the expected layout is a time consuming and error-prone task. It adds little value, but a lot of development effort, to the resulting apps – even more so if multiple device types are to be supported. SwiftUI addresses these challenges, improving application quality and decreasing development effort.

Decentralized Apps: Key concepts

Decentralized Apps (a.k.a Dapps) are something we’re very familiar with at Theorem. It’s been a strong theme of research for us over the last year and something we’re starting to write more and more about.

Switching the camera on an iPhone while recording

Not too long ago I was asked whether it was possible to continuously record a video while switching your camera from front to back on an iPhone. Neither the standard camera app or the standard camera control would allow this behaviour, but I suspected we may be able to do so with a custom solution.
