Don’t worry.

Trig is not hard ☺️

Compared to what you’re also gonna learn 🤣

What about the third way?

You freak…

Reducing your meat consumption is likely the most effective way of lowering your personal climate ‘footprint’.

You don’t even have to go fully vegan. Use 20%, 30% or 50% less meat and you’re already doing a lot.

Also look up climate impact of different types of food (and where it comes from), and use that to prioritize. Chicken, fish and pork are up to 10 times less impactful than beef.

I’m stuck on windows in the IDE of a certain large chip manufacturer for doing embedded DSP. God, I wish I could have any level of customization. But at least it has vim mode.

Yeah, I just included the DNS part for completion’s sake 🙂

I changed my local subnet to 10.1.2.0, because it’s much easier to type.

The client will look up your domain at whatever DNS it uses. It will return your public IP.

Client will send a packet with that as destination. It will reach the router which goes ‘I know! The call is coming from inside the house!’ and sends it to the server without modification.

The server gets it and sends a response, but the response is addressed back to client’s local IP.

Client gets the response, but that packet’s origin (in the header) is server’s local IP.

Client goes ‘wtf, I didn’t call you?!’ And drops the packet, still waiting for a response with your public IP as its origin.

This can be solved with the router modifying the appropriate traffic’s headers so that the headers match the expected, called NAT Loopback, or by using IPv6 global addresses.

It might also work running a local DNS server that returns your server’s local IP for a given domain, but that might yield certificate errors, and won’t work if devices ignore the DNS coming from DHCP.

I was using straight firewall rules for some years, but lost the template when the NAT Loopback checkbox started working (OpenWRT).

Touché

Back in University (2010-2013), I lived in a dorm on campus that had internet through the university’s network.

It was extremely cheap and fast (100/100 at equivalent to 3 USD per month), but Internet access was metered with a max of 50 GB / month.

However, access to University resources was not metered, and every student had ssh access to the datacenter.

That -D was a godsend.
