Can you calculate the weight of a sphere of 9 m of displaced water ?
No ? Well, it is 382 tons.

Metric strikes again.
I bet you didn’t even have to convert through football fields, elephants, or olympic sized swimming pools!

It could just do with a UI refresh and maybe some added functionality

That is actually huge ask.
Mumble works in an “engineer brain” kinda way. Cause it has been made by engineers making sure the underlying tech is available to be used in so many scenarios.
Making it work in a “user” kinda way is a huge change.
And it would either make the code really difficult to maintain, or would isolate the power users by restricting the flexibility of mumble.
The fact that mumble is FOSS is absolutely fantastic!

Feel free to fork the project and refresh the UI.
Or sponsored programmers to do this. If there is actually a market, you would be able to overtake mumble. You can even start from their codebase, the license is very permissive (just make sure you credit mumble!)

Yup. parseInt is for strings.
Math.floor, Math.ceil, Math.round or Math.trunc are for numeric type “conversions” (cause its still a float)

Sometimes it feels like postgres is cheating (in a good way)

I have no idea, but that website is a bit of a red flag to me.

It sounds like it’s some sort of file sharing service. So you can upload, share and download files from the RealDebrid servers.
A quick Google suggests it’s primarily used for downloading/streaming movies, TV series etc. Essentially piracy.

Chisel, Rathole, an SSH tunnel with port forwarding, a VPN with port forwarding.
Keywords are “self hosted tunnel” or “reverse proxy over VPN”.

Run a VPS for like $5 a month, your local reverse-proxy tunnels out to the VPS, and your VPS forwards port 80/443 over the tunnel to your reverse-proxy.

Uh, don’t?
You want a Lemmy instance - that I presume you would want to be somewhat reliable - without doing anything? WiFi prioritises convenience over speed and reliability. So, things will randomly fail.

I guess pay for a Lemmy instance provider. Probably the easiest. But this is self hosting, and it sounds like you want a place to start and have chosen “hosting a Lemmy instance” as your learning ground.

Something like cloudflare tunnel will let you punch through a firewall without having to mess with network stuff.
A docker compose stack makes things as easy as they can be in such scenarios.
These are terms you can google “Lemmy docker compose cloudflare tunnel”

Here is 1 result: https://lemmy.world/post/299429

Here is a GitHub for Lemmy in docker compose https://github.com/Drakeyves/lemmy-docker-setup

This looks like it covers cloud flare in a compose stack: https://joelparkinson.me/self-hosting-with-cloudflare-tunnels-docker-compose/

Read through, learn docker compose, understand cloudflare & cloudflare tunnels

Wouldn’t it be better to have highly available storage for the git repo?
Something like Ceph, Minio, Seaweedfs, GarageFS etc.
Cause git is file system based.

my router and my reverse proxy (traefik) is able to receive the necessary SSL/TLS certificates however

From something like LetsEncrypt?
As an HTTP-01 Challenge? Not an DNS-01 challenge?
Http challenge means that port 80 is accessible from the public internet (because that’s how LE can confirm it can reach your server via the public DNS records, proof of server ownership).
DNS-01 is about proof of DNS record ownership, and doesn’t prove public internet access.

Also, what are you self hosting?
Does it really need to be publicly accessible? Or just accessible by you and people you trust?

Sounds like you have had a very productive life! Your son is very lucky.

Encourage the education. But there are loads of good careers that don’t need university degrees.
And all the while, he can try and achieve his dream.

From personal experience, university wasn’t useful for me - other than giving me time to figure out what I don’t want to do, and meeting friends that are still friends to this day.
But I could’ve easily done an apprenticeship, or gone straight into some industry/company. Some days, I wish I had. Other days, I wouldn’t want to be doing anything other than what I am atm.

Dream case, he makes it.
Best case, he figures out what he wants to do by 21.
Worst case, he’s still figuring it out when he’s 25.

I wasn’t making decent money until I was late 20s. Even now, I can’t guarantee I have enough work next year. It’s extremely likely, but I’m self employed so…
Knowing my folks will still support me means I can continue pursuing interesting, useful and innovative things, even in my 30s - even tho the support is no longer required.

Maybe talk to some of your contacts in the football industry.
See if they have similar “football or nothing”, or if they had backup plans.
Talk to some managers, coaches, sports scientists, medics etc.
Ask them how they would get into pro football. Ask them what happens to pro-football aspiring players that don’t make the cut.
Use your experience and connections to help and support your son. And be there if it doesn’t work out.
You might know better, but he still has to learn. The best lessons are mistakes.

Did you go straight into being a pro footballer? Or did you have back up plans? Like “if this doesn’t work out, I’ll be an electrician” or something?

I’ve never had super lofty goals, but my parents always supported me in what I wanted to do. They never tried to steer me, but they did ask pertinent questions about what I was planning at various points. Probably to hint at bad idea.
I feel like I could have asked them for money/support at any point for any of my projects/ideas/whatevers, and - after making sure I was serious - would have helped out however they could.
I have a very unique career at this point, and I am only in this position because of the eclectic experience I have. And it is completely unrelated to my dreams as a kid or what I studied at university.

Ultimately, he is growing up. He’s going to have to make mistakes.
I’d say you have to be prepared to support him as much as you can in his dream of being a pro footballer.
Maybe he won’t be a pro footballer, but he might get a satisfying career out of being football-adjacent. Medic, science, coaching.
Or maybe he will try it for 5 years and eventually realise it’s not gonna happen, and be an electrician.
Or maybe he will struggle for 2 years, realise he needs to double down, and make the cut a year later.

I had a friend when I was growing up that dreamed of being an RAF pilot. Everything he did was around that.
Due to some unfortunate life circumstances, that dream was ripped away in the space of a week. Completely out of anyone’s control, but he could no longer qualify as an RAF pilot.
He was heartbroken. He’s now an engineer/mechanic in the RAF and loves tinkering with cars.

He shouldn’t find another dream.
But he should be aware that dreams don’t always come about. And if this dream doesn’t, would he be happy in an adjacent career? Or something else entirely?
Help him research the backup plan.

You need to control a domain, so LE can verify you are the controller of the domain, then LE will issue you a certificate saying you are the controller of the domain.

For a wildcard LE cert, you need to use the DNS challenge method.
Essentially the ACME client (or certbot or whatever) will talk to LE and say “I want a DNS challenge for *.example.com”.
LE will reply “ok, your order number 69, and your challenge code is DEADBEEF”.
ACME then interacts with your public nameserver (or you have to do this manually) and add the challenge code as a txt record _acme-challenge.example.com. (I’ve been caught out by the fact LE uses Google DNS for resolution, and Google will only follow 1 level of NS records from the root authorative nameserver).
All the while, LE is checking for that record. When it finds the record, it mints a wildcard certificate.
ACME then periodically checks in with LE asking for order 69. Once LE has minted the cert, it will return it to acme.
And now you have a wildcard cert.

So, how to use it on a local domain?
Use a split horizon DNS method.
Ensure your DHCP is handing out a local DNS for resolving.
Configure that local DNS to then use 8.8.8.8 or whatever as it’s upstream.
Then load in static/override records to the local DNS.
Pihole can do this. OPNSense/pfSense can do this. Unifi can do some of this.

How does this work?
Any device on your network that wants to know the IP of example.example.com will ask it’s configured DNS - the local DNS that you have configured.
The local DNS will check it’s static assignments and go “yeh, example.example.com is 10.10.3.3”.
If you ask you local DNS for google.com, it won’t have a static assignment for it, so it will ask it’s upstream DNS, and return that result.
And it means you aren’t putting private IP spaces on public NS records.

Then you can load in your wildcard cert to 10.10.3.3, and you will have a trusted HTTPS connection.

Here is a list of LE clients that will automate LE certs.
https://letsencrypt.org/docs/client-options/

Have a read through and pick your desired flavour.
Dig into the docs of that flavour, and start playing around.

If it’s all HTTPS, consider using something like Nginx Proxy Manager (https://nginxproxymanager.com/) as a reverse proxy in front of your services and for managing the LE cert.
It’s super easy to use, has a decent GUI, and then it’s only 1 IP to point all DNS records to.

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.

I was aware of kubernetes 6 months ago, but had never used it.
I got a 3 node cluster running in a day, and was learning kubernetes.
The only issues I’ve had were due to hardware failure causing etcd instability, and misconfigured operators generating terabytes of logs leading to pod eviction.

I don’t know what would signify it being production ready. It had all the levers and knobs I needed. I haven’t yet needed to run a sysadmin debug container to poke around the host OS.
It’s also great for learning. If you make a mistake, it’s very easy to wipe and reinstall and get back to where you were.

Talos is great

I see no reason you can’t use yaml.
Yaml and json are essentially identical for basic purposes.

Once the scraper has been confirmed working, are you going to be doing a lot of reading/editing of the raw data? It might as well be a binary blob (which is a bad idea as it couples the raw data to your specific implementation)

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

And in rust!

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

Pretty sure that and the White House advert halted the dip the last few days.
Except fElon hasn’t changed, so down it goes!
