Theory of Remnants, Followed by Barry O'Reilly
Get ready for an exciting discussion on the canvas of software design as Eberhard Wolff, a renowned software architect and blogger at iX, delves into the Residuality Theory. On Friday, September 19, 2025, from 1 to 2 PM, viewers can tune in to the live stream on YouTube (Heise Medien) to witness this groundbreaking event. During the live stream, viewers can ask questions via Twitch Chat, YouTube Chat, Bluesky, Mastodon, Slack Workspace, or anonymously via the form on the video cast page. Barry O'Reilly, an experienced architect who works as Head of Architecture at SWAGLab, will be the guest speaker, discussing the Residuality Theory in an English-language episode of the video cast, software-architektur.tv. This video cast, created by Eberhard Wolff, has been a staple since June 2020, with over 250 episodes now available. The video cast page provides more information about the episodes, and iX (our website Developer) integrates the episodes of software-architektur.tv into its online channel. The Residuality Theory is a new software design theory aimed at facilitating the development of software systems for complex business environments. It employs applied complexity science and models software systems as interconnected residuals, an alternative to component and process modeling. One of the fundamental aspects of the design process in the Residuality Theory is uncertainty. Barry O'Reilly will also be giving a workshop and a talk on the Residuality Theory at the Software Architecture Gathering in Berlin from November 24 to 27, 2025. He is associated with the revolutionary new Residuality Theory of software design. Don't miss this opportunity to learn about the future of software design! If you can't catch the live stream, don't worry – the recording will be available afterwards.
