  • In much of California, it’s not the electric energy costs that are high, it’s the delivery/grid fees. Not that it matters as far as the electricity bill goes, but it’s worth noting.

    On my recent bill I paid 16¢/kWh for on-peak electric generation and 49¢/kWh for electric delivery. (There’s a small baseline credit for delivery so it’s a little more complicated, but you get the idea.)

    So if someone tries to tell you electricity is expensive because CA is a hippie state with lots of solar, I would be a little skeptical.





  • Yeah I’ve been very happy with them.

    No experience with their software, but the service is great — I have an ARM SBC with WireGuard handling my tunnels, and my router does the rest (so my TV/guest SSID/personal SSID/whatever can get routed over Mullvad with no client setup). My DNS forwarders are each routed through a different Mullvad interface too.














  • That’s exactly my point, there are two different colloquial ways of talking about angles. I am not claiming there is a mathematical inconsistency.

    Colloquially, a “triangle has 180 degrees” and a “circle has 360 degrees.” Maybe that’s different in different education systems, but certainly in the US that’s how things are taught at the introductory level.

    The sum of internal angles for a regular polygon with n sides is (n-2pi. In the limit of n going to infinity, a regular polygon is a circle. From above it’s clear that the sum of the internal angles also goes to infinity (wheres for n=3 it’s pi radians, as expected for a triangle).

    There is no mystery here, I am just complaining about sloppy colloquial language that, in my opinion, doesn’t foster good geometric intuition, especially as one is learning geometry.
