The tilde (~) means that path is located in the per-user home directory. The default behaviour is for user home directories to be only accessible by that specific user.
The encryption you're referring to is likely specific to Firefox Sync (i.e. syncing your FF settings, history, etc. across devices). Sync is end-to-end encrypted. But I'm not surprised that it's unencrypted on disk.
The simple answer is yes.It's possible to encode or tunnel anything over any protocol.
The next question is why isn't it done more?
http has basically become the defacto internet protocol for all media content. This has resulted in a lot of other protocols from becoming blocked due lack of support or due to firewall rules.
efficiency. http (and all the other protocols it runs atop) have become highly optimized for doing what it does. To layer something like http over another protocol, would certainly be possible but it would likely be slower, less responsive and lack a lot of the niceties that make http work as well as it does.
For the above reasons it's actually more common to see other protocols run on top of http. This is especially common to prevent blocking and censorship by making the traffic look like normal http traffic when it may actually be private messaging apps, file transfers, VPN, etc.
You have your end grain slab laid on a table in front of you.
From left to right divide cut it into parallel pieces (width of these is up to you 2" or 3" is probably fine). With them all laid on the table on their original pattern, rotate or flip alternating slices. Glue it up.
The bigger the wood the more movement it will have.
End grain boards like you describe often have their pieces oriented in opposing directions to manage the warping due to expansion and contraction. Plus the more pieces the more glue jointing holding it together.
To provide more stability, you could cut a series of slices and flip every other one such that the curve of the grain is alternating.
5:1 (mineral oil:wax)
To add to the above comment, this is effectively what's sold as "cutting board wax/oil".Paraffin, soy or bees wax would all be fine. In my experience buying bees wax flakes is the cheapest way to get bees wax, it's often sold for use in cosmetics.
