Doordash and uber eats take a 40-50% cut from the restaurant when a driver delivers the food. Other platforms take 20ish percent if the restaurant does the delivering. I’m sure you could establish some kind of self hosted network where each restaurant runs their own machine that provides some of the compute. It would have to scale really well with such a decentralized system. You’d probably have to let the restaurants individually decide the amount they want to pay the drivers, and even then it would take a long time to build up a network of drivers. I think there would be a lot more problems with a decentralized approach though as you’d now have to let restaurants figure out disputes with drivers and customers when food goes missing and things. Pros and cons, and a lot of effort.

Okay sure, for a specific use case yes you can point a record to a private IP, however this explicitly doesn’t expose your homelab to the web. I misunderstood OPs intention.

You can’t point to 192.168.X.X that’s your local network IP address. You need to point to your public IP address which you can find by just searching ‘what is my IP’. Note that you can’t be behind CGNAT for this, and either need a static IP or dynamic DNS configuration. Be aware of the risks involved exposing your home server to the internet in this manner.

When an overwhelming proportion of the population is elderly, an overwhelming proportion of the working age populations earnings have to will go to support them. This is measured by an economic ratio known as the dependency ratio which is going to get out of hand for countries like Japan. The strain on public finances paying for pensions and healthcare reduces quality of life for everyone in the country and depresses economic growth as young people working to support the countries elderly population and their own parents have less to invest in the wider economy.

Standard resin becomes very weak at even low temperatures. There are special heat tolerant resins you can buy though.

It shouldn’t be, but German Auto makers are extremely slow to evolve due to their ridiculous bureaucracy. They’ve had ages to get on top of it and ignored it and they should pay the price for that, but they’re too big to fail for their countries economies. They’re definitely beginning to waver in the face of competition from china, so this comes across as the EU giving them a final respite to really start competing. Then again, could just exacerbate their complacency, we’ll have to see whichever way it goes.
