DNS and domains are just human-friendly IP addresses.

You only have 1 public IP address.
So, to access different services you need to use different ports.
Or run a service on a single port in front of the other services that can understand the connections and forward the connections to the actual services - known as a reverse proxy. In the case of http/https, there are plenty of reverse proxies that can direct requests based on all sorts of parameters, subdomains being one of them.

If you are just starting out, I’d recommend a docker compose stack and Nginx Proxy Manager.
Learning containers & docker makes everything easier.
NPM is a very easy to use reverse proxy with a nice GUI, so you don’t have to configure CertBot/ACME or learn the specific config language of Nginx.

If you are unsure of domains and all that, you can try it out for free.
Your computer has a hosts file (/etc/hosts on Linux, I think it’s in system32 on windows). This allows you to tell the computer “for the domain example.com use the IP 10.0.0.200” or whatever you want. You need a hosts file entry for each subdomain.
What this means is that you can run up a docker compose stack on your computer and point a bunch of sub domains to 127.0.0.1, use self-signed certs, and play around with nginx proxy manager and docker.
No money spent, no records published, no traffic leaving your computer.
Zero risk.

There are loads of tutorials out there on NPM and docker compose stacks. Probably some close to your specific requirements.

Boooo

I do that, until some container has permissions issues.
I tinker, try and fix it, give up and use a volume. Or I fix it, but it never seems to be the same fix

That thing solved with NATO oversight?
I knew NATO was a good thing. They should get more countries involved in NATO

Just buy from the EU.

Yes, but…
The same could happen the the EU, as with any foreign power.
It’s unlikely as the EU is fundamentally built differently. But it could, no doubt a country that wanted to push through their adjenda by exploiting loopholes that haven’t been discovered/exploited because of “decorum” could still happen.

Buy source-provided.
So, you get everything you need to maintain the platform with the purchase cost.
If you want updates and improvements, they have additional cost.
Like so many software licencing models. 1 year of updates - except it’s source provided.
It’s more expensive, but you get what you pay for.
Renew your licence every year for another year.
Stop paying? You get to use the EJ69 fighter jet platform as it was in 2019 for as long as you can manufacture parts for it.

Or you could buy the cloud-hosted fighter jets. And risk the off-switch. But it’s less upfront cost, higher long-term cost

And keycloak has a decent k8s operator, making deployment on a k8s cluster a breeze

Well, I guess the EU is 26/27th decent.
However, the EU is working towards defunding (I guess pushing-to-change, aka punishing) shitty members.

So yeh, the EU isn’t perfect. It’s working on it, and it is making progress.
Nice when an oversight body isn’t corrupted

accessed from the internet

Accessed only by you and close family/friends who you are also hosting services for?
Or accessed by anyone?

“Accessed by anyone” carries more risk.

“Accessed by users you host for”, the risks can be eliminated (well, other than risks from those users) by using a VPN. As in, only the people authorised to be on the VPN can access the services.
Wireguard is the go-to these days.
Tailscale is much easier and free for 3 users and 100 nodes.

If it absolutely has to be “accessed by anyone” I would look into a “reverse proxy over VPN/tunnel” or just straight tunnel style approach like chisel (or crowbar, or corkscrew), rathole, frp, or cloudflare tunnels.

Basically, don’t point a domain at your home public IP and don’t forward ports on your home router/firewall

As an augmentation, the ability to spot and track objects visually would be amazing.
But then planes just have to fly above 10k ft, and pretty much guaranteed cloud cover.

Echolocation is specifically audio based.
Lidar is a similar technique, but much more accurate and precise.

Killing Donny wouldn’t change much, tho.
America has shown it wants Donald or a Donald substitute.

Project 2025 is now Americas playbook.

Other countries changing military suppliers isn’t going to change back to america for 10-15 years (hell, maybe even longer, I dunno what the service life of a jet platform is).
The risk that has surfaced of “America has an off switch” - even just the potential risk of rumors of an off switch - means all those military assets are useless when America elects unhinged leaders that are willing to subvert democratic process in order to run their playbook.
And America has shown it is willing to do that. Even prefers to do that

I guess it depends if the frame count is an in-game frame, or a recording of the gameplay.
If it’s in-game frames, then a slower newer snes has the advantage. You have more IRL time per “scored” unit of time.
If it’s frames of the video, then the faster barrel-aged SNES have the advantage, at the cost of requiring faster button presses

Speed running SNES games on og hardware is about to become extremely expensive at the top level

It’s a server with integrated UPS and KVM console.

No, from the UK.
I don’t understand how the US can want to have 100% paper ballots, but ban voting booths (which to me means, in person voting). This essentially leaves postal voting.
And USPS has been repeatedly targeted by right wing politics.

What kind of paper voting system is left without in-person, if USPS is compromised?

President Donald Trump on Friday [21st Feb 2025, I think] said he may put the U.S. Postal Service under the control of the Commerce Department in what would be an executive branch takeover of the agency, which has operated as an independent entity since 1970. https://apnews.com/article/trump-postal-service-usps-what-to-know-672db6c590837411ca3ba36966e374e1

So paper votes only, no voting booths… Leave postal votes. And the government controls the postal service.
What else is there?

If the postal service isn’t a political target, then post voting is excellent.
Ballots can be mailed weeks in advance, they can be collected by a deadline, they can then be counted.
But we’ve seen Americas right wing go after USPS, so - quite frankly - I don’t see any way it is as fool-proof as in-person voting.
Voting day needs to be a holiday, or employers need to give PTO for voting.

None of which will happen.
Voting booths will be banned.
USPS will be compromised/defunded to the point it can’t carry out it’s duties.
Only the people that can schedule the time with Electoral College personnel will be able to actually register a vote.

You know, I have no idea.
I think it depends on the linked-to servers.
If the server thinks the Lemmy thumbnail/summary generator is a bad bot, it will not return a thumbnail. If it’s actually a decent web server, I think the Lenny instance will generate & distribute a thumbnail automatically and attach a summary.
I presume this is handled by the posts hosting instance.

I’ve noticed some sites that get linked to don’t have a thumbnail and some sort of “prove you aren’t a bit” subtext/caption.
And others work fine

It’s an autoshooter isn’t it?
Vampire Survivors would be a rogue-like autoshooter.

Like Backpack Battles is an autobattler.

Edit:
As raised in the comments, actually a rogue-lite as VS has meta-progression.
