Sustainable Computing: What backend developers can do to help
The climate crisis is real, and by some metrics computing uses more energy than aviation. We all need to do our part, and in this talk I'll highlight some ways to measure energy impact, discuss some patterns and antipatterns for sustainability, and some ways to start the conversation about energy usage at your organization.
Modern Sandboxing: Using Web Assembly in Java
Running untrusted third party code is not a good idea. It is also really useful. In a browser we do that literally all the time, but on our servers we are much more hesitant. That is where sandboxing comes in. Sandboxing allows us to run code and only let it touch what we want it to touch. For this we will be looking at Web Assembly, a promising binary form, born on the web, to use in our services. We’ll have a look at Extism, a framework that lets us integrate web assembly into our Java codebase with ease.
