Apache Karaf mentions (1)

  • Need advice: Java Software Architecture for SaaS startup doing CRUD and REST APIs?
    Apache Karaf with OSGi works pretty nice using annotation based dependency injection with the declarative services, removing the need to mess with those hopefully archaic XML blueprints. Too bad it's not as trendy as spring and the developers so many of the tutorials can be a bit dated and hard to find. Karaf also supports many other frameworks and programming models as well and there's even Red Hat supported... Source: over 5 years ago

FlowSavvy mentions (1)

  • Task management app
    Since you mention also wanting to plan your schedule better, FlowSavvy might be worth a look (I helped build it). You throw everything in the todo list, and it'll do the planning into your calendar for you. Then if anything comes up, it automatically reschedules. Definitely makes scheduling tasks less tedious.
