Sliding sync was recently implemented in Synapse itself, so as long as your Synapse is up to date there shouldnt be any more setup on the matrix side. Try checking the Synapse logs for any issues and/or the cloudflare tunnel configuration (I have no idea about what it does to traffic).

Same. Imho it shouldnt even be possible to build this.
What overlay? That looks like Windows 7 with the Aero theme disabled to me.
Is it, really? It is Turing Complete, after all.
It doesnt even matter, TTL is only decreased when routing. Ethernet frames have no such concept.
Well, kinda the same price, they sometimes up it to account for inflation. I do see the DLC difference (this could be said to be an equivalent of for example Minecraft Dungeons with the amount of content, but I see how it is kinda "more of the same"). Anyway, the 2.0 update does bring a lot to the base game for free.
How about Wubes Factorio?
I see why automatically giving them out (like in ACME) would be a bad idea, but other than that, why not? Even https://1.1.1.1 has a DigiCert cert.
There are more reasons, as LetsEncrypt might be more restrictive on what you can get (for example, you cant get a certificate for an IP address from them). But, as 99.99% of usecases do not require anything like that, go with letsencrypt until you know of a reason not to.
Note that Git doesnt store deltas. It will reuse unchanged files, but stores a (compressed) version of every file that has existed in the whole history, under its SHA1 hash.
I recently migrated from Element to Element X with first the proxy and now simplified sliding sync, and it feels way faster. Imho Element X is still very alpha software, so I wouldnt recommend it to the general population just yet (and I still occasionally have to open the old Element), but the speed is really noticeable on even a very small instance.
