It outlines 5 trends: 1) increasing software complexity, 2) raising abstraction levels, 3) continuous process improvement, 4) adapting to changing requirements, and 5) experience reuse to address recurring problems. It promotes agile principles and software reuse benefits and challenges.
The document discusses Android application processes and threading. It explains that Android uses a process for each application, with each process having its own virtual machine. The zygote process is used to spawn new processes for apps. By default, each app runs on its own thread but additional worker threads can be used for long tasks to avoid blocking the main thread. AsyncTask is introduced as a common pattern for moving operations to a background thread. Services run in the background without a user interface and can be used for long-running tasks.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
