For another email provider alternative, I would suggest Forward Email. I still haven't used them yet, but my goal is to switch to them from Proton when I get around to it.

I was thinking of playing around with email hosting, at least for offline backups, and I've been interested in using Stalwart.

I also suggest Porkbun for purchasing a domain.

Many Signal alternatives also have security issues of their own, often making them less secure than Signal. This includes Matrix and XMPP. In the blog post regarding XMPP+OMEMO, the author replies to a question about which would be better than Signal, Matrix, and XMPP with this suggestion:

Anyone who cares about metadata resistance should look at Cwtch, Ricochet, or any other Tor-based solution. Not a mobile app. Not XMPP. Not Matrix.

In regards to Ricochet, not having a mobile app version makes it difficult to recommend to less tech savvy people.

This is how to trim a curve on a point in FreeCAD. Honestly hilarious. Tried using it recently, and I couldn't follow a basic tutorial without it breaking. This is a recent fair review of FreeCAD, and it still needs a lot of work even after its 1.0 release before it is worth using. I'm considering going back to OpenSCAD for a simple project, and then I will try using build123d in python (CadQuery is a more user-friendly alternative, at least as far as I am told).

I'm curious how well these CAD kernel projects written in Rust will turn out: Fornjot / Truck

I run udisksctl unmount -b /dev/sdX# in the terminal. When it completes, it means the files have finished copying and the partition was unmounted.

I was able to get some Linksys E8450 routers for cheap (~$40 each) on eBay a couple years ago, but they are more expensive atm (but $70 each, which is cheaper than a lot of other options). They require a bit of work to get OpenWRT installed, but it's not bad once the work is done (I have received nearly 400 Mb/s when I am close to the wireless connection sometimes, which is what my internet is capped at). I have used them as a mesh with one as a main gateway and the rest as access points with additional Ethernet ports. They do have the OKD issue fixed now, too, and they're also Wi-Fi 6. I'm looking into getting a Banana Pi BPI-R3 or R4, though I am not sure how well they are with mesh specifically, but have seen a few forum threads of people having some issues with mesh on these specific routers. I hope to switch to fast roaming (wired backhaul) eventually.

"I have never really understood exactly what a 'liberal' is, since I have heard 'liberals' express every conceivable opinion on every conceivable subject. As far as I can tell, you have the extreme right, who are fascist racist capitalist dogs like Ronald Reagan, who come right out and let you know where they're coming from. And on the opposite end, you have the left, who are supposed to be committed to justice, equality, and human rights. And somewhere between those two points is the liberal.

As far as I'm concerned, 'liberal' is the most meaningless word in the dictionary. History has shown me that as long as some white middle-class people can live high on the hog, take vacations to Europe, send their children to private schools, and reap the benefits of their white skin privilege, then they are 'liberal'. But when times get hard and money gets tight, they pull off that liberal mask and you think you're talking to Adolf Hitler. They feel sorry for the so-called underprivileged just as long as they can maintain their own privileges."

I hope there will be native Linux support, even if it comes a few years after it is released. CrossCode is supported on various platforms, and it even has a web version for its demo.

I will be honest, I haven't came around to using XMPP myself yet, but I am pretty sure you are able to do all of those things, at least with the help of extensions. Here's the XMPP standards that are currently stable or experimental:

Files/Images:

• XEP-0363: HTTP File Upload [Stable]
• XEP-0446: File metadata element [Experimental]
• XEP-0447: Stateless file sharing [Experimental]
• XEP-0448: Encryption for stateless file sharing [Experimental]

Emojis/Stickers:

• XEP-0444: Message Reactions [Experimental]
• XEP-0449: Stickers [Experimental]

Looking at clients, I see various ones that have at least some of the features you are looking for (especially file and image sharing, I haven't found a client that has explicitly implemented the stickers specification yet, but Movim seems to have them):

• Converse.js
• Dino
• Kaidan
• Movim
• Profanity

I would give it some more time. It seems those features are in development, but this is essentially an alternative to Matrix that is more standardized. It's a widely adopted and integrated protocol, so I don't doubt the features you are looking for will become more fleshed out some day.

XMPP it is, then.
