J3400 to J1772 adapter + DCFC = ???

If I understand it correctly, J3400 requires bidirectional data link with the car before connecting DC current. J1772 is a simpler pilot voltage/resistance value across the two signal pins, which the DC charger won't recognize. So, nothing would happen if you plugged that adapter into a DC charger.

That's a good question. There will have to be something to prevent DC from being applied to the j1772 pins when using the wrong adapter.

I haven't seen any technical info on how the DC adapters will work. I'm just guessing, but I would assume that the DC adapters will be active and take part in the handshake between car and charger. If you try to use a passive adapter, one side or the other would determine that the DC pins are not physically connected and refuse the handshake.

So, magic!

Why PHP is Still Alive? Or Why Node Can't Kill It.

I write PHP professionally, so I agree with his conclusion, but this is a strange take:

Enterprise developers are usually working in large teams with DevOps support, continuous integra- tion pipelines, containerized deployments, observability, and more. In contrast, web develo- pers building small business websites, forums, blogs, or landing pages have to prioritize and opti- mize for cost and simplicity.

This is where PHP shines: the deployment model is dead simple. Write code > Deploy via FTP > You're live.

All of the things in the first quoted sentence can be and are being done with PHP. And in the enterprise, cost and simplicity are still seen as high priority.

What's up, selfhosters? It's selfhosting Sunday again!

I finally bought a tiny PC to replace my aging APU border router/firewall (OpenBSD), so I'm trying to wrap my head around building a router currently inside the network that it will be protecting.

I have Debian installed as hypervisor, Incus, and sticking with OpenBSD for the firewall. pf makes too much sense to me too switch to firewalld. I'll also move the network-related containers off my main lab host once this is up and running.
