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

  • Ask HN: Looking for a DJ Program
    To "live DJ" there's the extremely famous https://virtualdj.com/ To create prerecorded DJ sets https://www.mixmeister.com/ Been using both for at least 10 years, love them both. - Source: Hacker News / over 2 years ago
  • Ask HN: Looking for a DJ Program
    Not open source, but free for "home use" https://virtualdj.com/. - Source: Hacker News / over 2 years ago
  • Can you help me to start?
    I started with Virtual DJ to get used to the software latency (I came from turntables) and get my muscle memory on button locations (which is why I stayed with the same brand). VDJ has every feature you need. The software is free to use without a controller from virtualdj.com. Source: almost 4 years ago
  • Music & video playlists at Oz/Goodfriends/etc
    A lot of the places that do it from scratch I notice use https://virtualdj.com/. Source: about 4 years ago
  • A-B Looping software for background music in D&D/RPG games?
    DJ software, like VirtualDJ will have features that are more conducive to what you're trying to do, like live looping functions that help you lock the loop to the beat. It's also cheaper (free for non-commercial use without a hardware controller) than QLab, and it's cross-platform (QLab is Mac-only, if that matters). Source: about 4 years ago
