This document discusses using UIKitDynamics in Swift. It provides examples of using UIDynamics for screen transitions, animating UIViews, and controlling multiple objects in a UICollectionView. For screen transitions, it demonstrates implementing a transitioning delegate and animator. For animating UIViews, it shows using a UIPanGestureRecognizer and UIAttachmentBehavior. For UICollectionView, it overlays a UIDynamicAnimator on the layout to animate cell positions. However, the presenter notes some limitations, such as being forced into un-Swifty implementations and occasional animation issues.

This document discusses how to use threads and concurrency in iOS development to take advantage of multi-core processors. It notes that as processors have increased cores, iOS devices now have dual-core or quad-core CPUs. The document recommends using threads and concurrency through Grand Central Dispatch or operation queues to perform tasks in parallel without freezing the user interface. It provides examples of animations, network requests, and long-running tasks that can benefit from threads. It also warns that some UI-related tasks must remain on the main thread.

Protractor Tutorial Quality in Agile 2015Andrew Eisenberg

Andrew Eisenberg gives an overview of UI testing with Protractor. He discusses installing and running Protractor, writing basic tests, more complex test scenarios using page objects and promises, debugging tips, and considerations around when and how to use Protractor for UI testing AngularJS applications. While Protractor is a powerful tool, he notes it has limitations and maintenance costs, and manual testing may be better for unstable UIs and use cases in flux.

Formal Methods: Whence and Whither? [Martin Fr?nzle Festkolloquium, 2025]Jonathan Bowen

Alan Turing arguably wrote the first paper on formal methods 75 years ago. Since then, there have been claims and counterclaims about formal methods. Tool development has been slow but aided by Moore’s Law with the increasing power of computers. Although formal methods are not widespread in practical usage at a heavyweight level, their influence as crept into software engineering practice to the extent that they are no longer necessarily called formal methods in their use. In addition, in areas where safety and security are important, with the increasing use of computers in such applications, formal methods are a viable way to improve the reliability of such software-based systems. Their use in hardware where a mistake can be very costly is also important. This talk explores the journey of formal methods to the present day and speculates on future directions.
