Some thoughts for selecting software used for teaching over the internet.

• Open Source
  • These are all privacy friendly and free of charge
  • software: Jami:
    • pro: peer2peer, after server initially establishes connection
    • https://jami.net
    • TLS1.3 end2end encryption.
    • functionality: chat, audio-call, video-call, exchanging files
  • software: Jitsi meet
    • con: requires server, but the free default one might be sufficient
    • issues with videochats of 35+ persons
    • details
  • software: Big Blue Button
    • con: requires server
• Proprietary code base
  • Here one has to trust the vendor regarding privacy. Codebase can not be audited by everybody.
  • software: Skype
    • con: account required
    • pro: no own server required
  • software: Google hangouts
    • con: account required
    • con: just 10 participants possible
    • pro: no own server required
    • hangouts is free and for private, google meet is commercial for business
  • software: Zoom
    • con: recent security issues
  • software: Bluejeans
  • further: Microsoft teams, Facebook, Apple facetime (Apple devices only), Cisco Webex
