Communication Services

Information also available in German.

We offer several communication services to you, to ease social interaction and studying.

Login / Authentication

Students of Computer Science can login with their normal stu-account.

Students of Mathematics can unfortunately not logon to our services for now. We hope to change this soon.

Riot/Matrix

This service was shut down 2021-03-21. This was due to apparent very low usage.

https://riot.fs-infmath.uni-kiel.de

Element (former Riot) is a modern chat program. Matrix the name of the corresponding protocol.

Features:

• Public chat rooms
• Private chat rooms
• Optional end-to-end encryption of chat rooms
• (Video) Calls between two people (via WebRTC)
• Video conferences via Jitsi

Chat rooms may for example be set up for small groups collaborating in a course or large ones like all the attendees to a certain course.

Usage

• Web frontend
  • Recommended: Firefox or Chrom{e,ium}
• Desktop client, Apps for Android (F-Droid, Google Play) and iOS (App Store)
  • As homeserver, set <matrix.fs-infmath.uni-kiel.de> (not <riot.fs-infmath.uni-kiel.de>).

CodiMD

https://codimd.fs-infmath.uni-kiel.de

CodiMD is a collaborative Markdown-editor.

Features:

• Simultaneous editing of the same document (e.g., homework) by several people.
• Markdown, a very simple markup language, close to plain text.
• Real-Time rendering of the HTML corresponding to the typed Markdown.
• Syntax highlighting for several programming languages.
• LaTeX-Rendering.
• VIM and Emacs modes.
• Many more, see CodiMD/Features.

Jitsi

This service was shut down 2021-03-21. This was due to apparent very low usage.

https://jitsi.fs-infmath.uni-kiel.de

Jitsi is a videoconference server.

Features:

• Videotelephony in small groups. Larger groups do unfortunately seem to cause problems.

May for example be useful to coordinate or collaborate in small work groups.

Nutzung

• Preferably via Chrom{e,ium} (with hardware acceleration), alternatively Firefox.

Mumble

Mumble is deprecated might be shut down in the near future. If you are still using Mumble, please e-mail us at technik@fs-infmath.uni-kiel.de.

mumble://mumble.fs-infmath.uni-kiel.de

Mumble is a voice chat program.

Features:

• Permanent and temporary channels (like Riot/Matrix, but independently).
• Should handle larger groups well.
• Ressource-efficient.

Useful, whenever vocal communication suffices. E.g., in combination with CodiMD.

Nutzung

• A client program needs to be installed. Available for all major operating systems (incl. mobile).

Further options

A few suggestions on further technical options for collaboration:

• VIM / Emacs in a shared Screen / Tmux - session.
  • E.g., on one of the Servers of the Department of Computer Science reachable via SSH.
• Drawpile -- collaborative drawing
• Further options on libreplanet.org.

Questions, Remarks, Wishes

Feel free to contact us:

• via E-Mail: technik@fs-infmath.uni-kiel.de
• via Riot/Matrix

Notes

• All provided services are running on virtual machines at the Department of Computer Science. These are administered by the Technics-Team of the Students' Association of Computer Science and Mathematics. On the virtual machines, exclusively Free and Open Source Software is in use.

• We consider further services to offer later. If you have any suggestions (or maybe would like to help), we hope to hear from you.

• The so-called federation of Riot/Matrix has been turned off on the provided instance, due to unresolved questions on data protection.
