Should you rebuilding or refactoring software?An interview with Wouter Lagerweij about what it is that makes refactoring so difficult, if rebuilding software is less risky than refactoring, and how continuous delivery fits with rebuilding software.
Many teams now implicitly discard continuous integration due to ever-easier feature branching and an under-appreciation of trunk based development says Steve Smith. InfoQ did an interview with him about different branching approaches and how they can be combined with continuous integration, and how using build feature branching can hamper continuous integration and continuous delivery.
Where many organizations use agile to develop IT products, agile principles and practices can also be applied for maintaining landscapes of commercial products. Gert Florijn and Eelco Rommes will talk about directing complex IT-landscapes in public sectors such as healthcare and local and national government organizations at the Agile and Software Architecture Symposium 2015.

An interview with Rob Howe, host of the MDSE session at the software engineering conference and CEO of Verum, about the state of practice and recent developments in model driven software engineering, the usage of this technology, whether he considers model driven software engineering to be a proven mature technology, and what the future will bring us in model driven software engineering.
GitHub has recently started revoking SSH keys that were deemed to be compromised or otherwise insecure. Systems engineer Ben Cartwright-Cox was the author of the research that uncovered the issues. InfoQ has spoken with him.
Hans van Wezep, software architect at Philips Healthcare, talked about model-based migration at the Bits&Chips Software Engineering conference. InfoQ did an interview with van Wezep about the challenges in maintaining legacy software, why manual refactoring is error prone, using models to refactor and migrate a codebase, and the benefits of using models when maintaining legacy software.
Total Cost of Ownership (TCO) can be used for investment decisions and financial benefit analysis. When applied to software it covers the initial development costs and subsequent maintenance costs until phase out of a product. TCO can support architectural decisions and management of technical debt.
