The long (after)life of some of our old fileserver hardware (utoronto.ca)
Over on the Fediverse, I mentioned that we were still running a machine in production that was old enough that its BMC required Java for its KVM-over-IP functionality (and I've given up on working with it, rather than try to maintain a Java environment that could actually work with it). Naturally there's a story here.

Services began to adopt JSON because it was a lightweight and efficient alternative to XML. However, even though JSON became the new standard, old services were still in use and being maintained.Rewriting a system from scratch is not easy, and it might not even be necessary.

Using the Strangler Fig with Mobile Apps (martinfowler.com)
Incremental replacement of a legacy mobile application is a challenging concept to articulate and execute. However, we believe by making the investment in the pre-requisites of legacy modernization, it is posible to yield benefits in the long term. This article explores the Strangler Fig pattern and how it can be applied to mobile applications. We chart the journey of an enterprise who refused to accept the high cost and risk associated with a full rewrite of their mobile application.
