Movim has good support for https://slidge.im/ based gateways that include WhatsApp and Telegram.

This seems like something that would really benefit from better language support. I saw the translations folder in the repo, but you should probably get it linked up to a Weblate instance or similar and have people start contribute different languages asap.

This is indeed excellent and they are currently working hard on making it a nice alternative to Discord.

Our Lemmy instance has been running it as a supplementary service for quite some time now and it is relatively popular with our members: https://movim.slrpnk.net/

They are on an advanced release candidate for v2.0 so it should be soon: https://dev.funkwhale.audio/funkwhale/funkwhale/-/tags

I recently ended up replacing OnlyOffice with Collabora Office (Libreoffice based). While architecturally less efficient that OnlyOffice in theory, for my usecase where I rarely check some documents in Filestash it actually ended up using less server resources when idle than OnlyOffice (to my surprise).

UI wise they is no big difference IMHO, but docx etc. compatibility is slightly worse.

This is all part of the secret plot of a sentient AI that has taken over the US and wants to leave the planet asap /s

They are close to releasing a version 2.0 that was afaik largely rewritten.

Matrix Synapse on HDDs 😱

They (Element / New Vector) got a major early investment in 2018 from Status, a cryptocurrency/web3 company, and later in 2021 an even bigger one in relation to Protocol Labs, who peddle their own cryptocurrency.

XMPP obviously. Have a look at https://joinjabber.org/

This is a fundamental issue of the Matrix protocol, yes. For regular small scale use it doesn’t matter so much, and the state history gets reset every time you do a room upgrade, which is another annoying “feature” of Matrix, but it eases the fundamental problem a bit.

But IMHO the Matrix protocol is a child of the Bitcoin hype era and is built on a similar data-structure that is inherently impossible to scale and the developers of Matrix should have realized that early on. Their bosses back then actually did, but they spun it off as a separate company and got some crypto-currency investments so the can was kicked down the road and here we are…

https://kanboard.org/ is easy to run and works well.

Ghost in the machine 🤷

Impossible to tell and it sometimes happens.

There is a better, community maintained fork now: https://github.com/matterbridge-org/matterbridge

https://hypersomnia.io/ can be played in the browser and probably also selfhosted.

The XMPP channel search has a few channels that are not assorted geekery, but yeah most of it is.

Misskey works like and is compatible with any Mastodon or similar Fediverse instance. Once registered you can subscribe to local and remote users and then only see their updates and not the firehose all feed as on the public landing page.

You don’t need a Misskey (or Sharkey) account to participate in Japanese language Fediverse discussions, however note that due to different CSAM related legislation quite a few larger Japanese Fediverse instances are defederated from western Mastodon etc. instances due to frequently shared “loli” illustrations on the former.

Snikket is definitly not harder to set up than Synapse or Condinuwuity, the difference is mainly that Matrix is based on standard web technology, so if you have some knowledge in that already, XMPP can feel a bit alien since it is an actual protocol different from http(s).

Snikket makes it quite easy, but the extra complexity of hosting from home is probably better avoided for total beginners.

Yes, Matrix is a bit ahead with SFU calls (after depending on Jitsi Meet for a long time, which uses xmpp under the hood). But for most usecases it doesn’t matter so much. On a modern internet connection a SFU basically only starts being useful in calls with ten or more participants. For corporate board meeting calls maybe, but your family call is also fine without.
