Hello Kang, I have done GSoC for XMPP Standards Foundation a few years ago. XSF in previous years was working as an umbrella organization for a number of smaller organizations. Checkout previous years projects https://summerofcode.withgoogle.com/archive/2020/organizations/515322437540… Some XMPP organizations joined previously also alone, without XSF so you can also look for them. As for Java projects go: Here is Conversations (Android client). https://summerofcode.withgoogle.com/archive/2018/organizations/603249108110… https://conversations.im/ https://github.com/inputmice/Conversations I think you can try to contact people in this MUC for conversations: conversations(a)conference.siacs.eu Java projects (Server, Client Library and Desktop Client ) are also done by Ignite Realtime Foundation ( I have done my project for them as part of XSF ): https://www.igniterealtime.org/ https://github.com/igniterealtime You are welcome to join this MUC: open_chat(a)conference.igniterealtime.org where I or someone else should answer your questions. ( If you don't have an account you can join anonymously through a web client https://www.igniterealtime.org/support/group_chat.jsp ). I hope I didn't omit any other Java projects participating in GSoC. Cheers, Paweł pon., 21 gru 2020 o 18:09 Kang Breder <kangbreder(a)gmail.com> napisał(a):
