= NLP Matrix communication server

All members of NLP Centre have access to https://nlp.fi.muni.cz/matrix, a [[Image(matrix-favicon.png,middle,link=https://matrix.org/)]] [https://matrix.org/  matrix.org] [https://github.com/matrix-org/synapse Synapse] server. Just use your faculty login and password to log in.

[[Image(nlp_matrix.png,right,width=30%)]]
The server may be accessed via a [https://matrix.org/ecosystem/clients/ number of clients] with the easiest being direct web access at https://nlp.fi.muni.cz/matrix where we have the [https://matrix.org/ecosystem/clients/element/ Element web client] installed. On a mobile phone, you may use its [https://play.google.com/store/apps/details?id=im.vector.app Android] or [https://apps.apple.com/us/app/element-messenger/id1083446067 iOS] versions.

The [[Image(matrix-favicon.png,middle,link=https://matrix.org/)]] [https://matrix.org/  matrix.org] clients are similar in nature do Discord or Slack, so its functionality should be well-known.

== What can you do

What you can do at [https://nlp.fi.muni.cz/matrix]:
* chat, ask, inform, discuss, give polls, ... with other NLP lab members
* test implementing new functionalities, e.g. Matrix [https://matrix.org/ecosystem/integrations/ integrations], [https://matrix-nio.readthedocs.io/en/latest/examples.html bots], or [https://github.com/element-hq/element-modules web modules].

== Rooms

By default, all users are members of the `nlp-all` and `random` rooms. But you can create rooms of your own, public and private, on any topic, organized in [https://element.io/blog/spaces-the-next-frontier/ spaces].

The room language is unrestricted - anyone volunteering to implement a [https://github.com/element-hq/element-meta/discussions/2150 Translate message] functionality? 

== Messages

All messages (especially in the Element web client) use [https://commonmark.org/help/ CommonMark Markdown] formatting (https://spec.commonmark.org/current/ full specification) which is very useful for sharing ''structured information''.

And remember - to write a ''newline'' in your message, use `Shift`+`Enter` 🤓

=== What is a 'device'?

For historical reasons, 'device' in Matrix does not mean your phone or your laptop - you actually create a new 'device' each time you log in on Matrix (and destroy it again when you log out).

=== Encryption off

When testing the server, we have come to cumbersome problems with properly handling ''encryption setups'' in Matrix (see e.g. [https://joinmatrix.org/guide/fix-decryption-error/ this article] or [https://blog.neko.dev/posts/unable-to-decrypt-matrix.html this explanation]) leading to inaccessible messages. To not bother with such problems, we have turned off the encryption in NLP Matrix rooms.
