It also means that ALL traffic incoming on a specific port of that VPS can only go to exactly ONE private wireguard peer. You could avoid both of these issues by having the reverse proxy on the VPS (which is why cloudflare works the way it does), but I prefer my https endpoint to be on my own trusted hardware.

For TLS-based protocols like HTTPS you can run a reverse proxy on the VPS that only looks at the SNI (server name indication) which does not require the private key to be present on the VPS. That way you can run all your HTTPS endpoints on the same port without issue even if the backend server depends on the host name.

This StackOverflow thread shows how to set that up for a few different reverse proxies.

And MATLAB appears to produce 51, wtf idk

The numeric value of the ‘1’ character (the ASCII code / Unicode code point representing the digit) is 49. Add 2 to it and you get 51.

C (and several related languages) will do the same if you evaluate '1' + 2.

Fun fact: apparently on x86 just MOV all by itself is Turing-complete, without even using it to produce self-modifying code (paper, C compiler).

If there happens to be some mental TLS handshake RCE that comes up, chances are they are all using the same underlying TLS library so all will be susceptible…

Among common reverse proxies, I know of at least two underlying TLS stacks being used:

• Nginx uses OpenSSL.
  • This is probably the one you thought everyone was using, as it’s essentially considered to be the “default” TLS stack.
• Caddy uses crypto/tls from the Go standard library (which has its own implementation, it’s not just a wrapper around OpenSSL).
  • This is in all likelihood also the case for Traefik (and any other Go-based reverse proxies), though I did not check.

No standard abbreviation exists for nautical miles but definitely don’t use nm because newton metres

Since as you mentioned Newtons are N not n, Newton meters are Nm. nm means nanometer.

Aurora is no longer maintained, but it still works just fine. It’s a Windows app, so not web-accessible or anything, but it’s free. It only contains the SRD content by default (probably for legal reasons), but there’s at least one publicly-accessible elements repository for it that you can find using your favorite search engine.

That domain currently hosts a “this domain may be for sale” page, but it’s been registered since 2005 so it’s definitely not because of this post.

Additionally, HTTPS if very easy to set up nowadays and the certificates are free¹.

¹: Assuming you have a public domain name, but for ActivityPub that’s already a requirement due to the push nature of the protocol.

AFAIK docker-compose only puts the container names in DNS for other containers in the same stack (or in the same configured network, if applicable), not for the host system and not for other systems on the local LAN.

I have a similar setup.

Getting the DNS to return the right addresses is easy enough: you just set your records for subdomain * instead a specific subdomain, and then any subdomain that’s not explicitly configured will default to using the records for *.

Assuming you want to use Let’s Encrypt (or another ACME CA) you’ll probably want to make sure you use an ACME client that supports your DNS provider’s API (or switch DNS provider to one that has an API your client supports). That way you can get wildcard TLS certificates (so individual subdomains won’t still leak via Certificate Transparency logs). Configure your ACME client to use the Let’s Encrypt staging server until you see a wildcard certificate on your domains.

Some other stuff you’ll probably want:

• A reverse proxy to handle requests for those subdomains. I use Caddy, but basically any reverse proxy will do. The reason I like Caddy is that it has a built-in ACME client as well as a bunch of plugins for DNS providers including my preferred one. It’s a bit tricky to set this up with wildcard certificates (by default it likes to request individual subdomain certificates), but I got it working and it’s been running very smoothly since.
• To put a login screen before each service I’ve configured Caddy to only let visitors through to the real pages (or the error page, for unconfigured domains) if Authelia agrees.

I believe on the free ARM instances you get 1Gbps per core (I’ve achieved over 2Gbps on my 4-core instance, which was probably limited by the other side of the connections). What you say may be correct for the AMD instances though.

For the ARM instances they’re a gigabit per OCPU, which you can get 4 of for free (assuming you’re lucky enough with availability), so you can theoretically get 4Gbps for free.

There’s a bit more to it than captured in the summary, which is why it’s just a summary of the spec and not the actual spec.

From a bit further down on that page:

4. Major version zero (0.y.z) is for initial development. Anything MAY change at any time. The public API SHOULD NOT be considered stable.

Lemmy is still in major version zero, so it can make breaking changes without incrementing the major version and still be in compliance with the spec. This way, projects won’t have their first “real” version be something like v123.0.0.

Lemmy still being v0.x also serves as kind of a warning to app developers that changes like this may be made at any time.

If you’re using OpenSSH, the IdentityFile configuration directive selects the SSH key to use.

Add something like this to your SSH config file (~/.ssh/config):

Host github.com
  IdentityFile ~/.ssh/github_rsa

Host gitlab.com
  IdentityFile ~/.ssh/gitlab_rsa

This will use the github_rsa key for repositories hosted at github.com, and the gitlab_rsa key for repositories hosted at gitlab.com. Adjust as needed for your key names and hosts, obviously.
