I’m maintaining a SaaS that reads the data from an ESP8266-based, Luftdaten-compatible air pollution sensor and displays it in a nice way.
Coffee GB
Coffee GB is a Gameboy Color emulator written in Java 8. It’s meant to be a development exercise and a way to learn about internal architecture of a retro game console.

Why did I spend 1.5 months creating a Gameboy emulator?
Carty
Carty is an integrated tool to create, edit, review and test Sling mappings for Adobe CQ/AEM.
SecureCQ
Secure CQ is a tool which can be used to find the most popular security problems in your CQ instance. It tests both instances (author, publish) and the dispatcher.
Sling Query
Sling Query is a Sling resource tree traversal tool inspired by the jQuery. It allows to avoid boilerplate code using convenient, functional API.
Sling Dynamic Include
SDI replaces dynamic generated components (eg. current time or foreign exchange rates) with server-side include tag (eg. SSI or ESI). Therefore the dispatcher is able to cache the whole page but dynamic components are generated and included with every request.

Zero downtime deployments for the Sling-based apps using Docker
Presentation shows how the Composite Node Store, a new Oak feature, can be used together with Docker to perform blue-green deployments. This kind of setup allows to dynamically change a part of the repository (containing the application code), while leaving the content part untouched.
