Well, the main purpose of this seems to be an eBook reader that integrates language learning and translation.
Its a good idea, but few language learners start out with a backlog of foreign language texts that they would like to read.
The exception would be your typical manga/light novel weebo, and this seems to be precisely what this is developed for with the Japanese language tools included.
The problem is Opnsense, as the BSD kernel used is doing single thread network routing. So the APU can saturate 1gbit with multiple connections/threads or if you switch to a firewall with a Linux kernel like OpenWRT.
That said, a N100 probably does have enough single thread performance to do 1.2 Gbit. Not sure about the full 2.5gbit though.
I met the main developer at the CCC congress two days ago, and we talked about it a bit. The problem is that he is only a backend developer, and the front ends for Friendica are a really old and messy codebase.
I think the best option for Friendica would be to fork one of the available alternative front ends for Mastodon and adapt it for the additional functionality of Friendica. But they need a frontend dev to help out with that.
The f-droid version should be ok for now, but if you installed this from the malware distribution channel aka the Playstore I would recommend to deinstall them before the next update hits.
Whatsapp is under the hood still a lightly modified XMPP system, and given Zucks recent comments about federated protocols (albright in a Threads i.e. ActivityPub context), they might just get their XMPP federation working again.
By typing in the numbers, or selectively sharing them from the address book. This works fine on Signal, Telegram and Threema. Only Whatsapp makes it so that you have to share your entire address book with the app.
With some workarounds you can actually use whatsapp also without giving it access to your address book, which shows that it is clearly an intentional dark pattern by Facebook to make people share their entire address book with them to avoid the hassle.
Also WhatsApp requests access to the phone book and is very hard to use if you deny access. This is very likely done because Facebook wants access to the stored numbers to build a social graph. Even if you personally don’t mind, it is a gross privacy violation to share the phone number of other people with Facebook.
