Canada and US are in negotiations to renew the Columbia River Treaty, where the US pays Canada for flood control upstream. They protect the cities along the Columbia River, and the hydroelectric infrastructure on the River, and the bridges. If Canada decides to play hardball, there’s a lot at their mercy.
Not really inhale-exhale, since they don’t have lungs. Kinda like when you sweat and you can feel the breeze cooling you under your arms. But instead of under your arms it would be on your neck, and instead of cooling you’d be respirating. But yes as the water moves past the gills, the blood is receiving oxygen and expelling CO2.
I have two TP-Link EAP610, one EAP245, and one EAP615-Wall. The Omada controller runs on my home server in an LXC. Three of the units are powered by PoE, and the garage one is meshed in. I needed three in my house because the walls have chicken wire in them which blocks and reflects WiFi. It took some trail and error to get the WAPs in suitable locations. The main one in the basement is under a wall, such that it has line of sight into 5 rooms of the house. I used iPerf to test performance at the edges of each room, until I could get at least 300 Mbit reliably. That was the only way I could ensure that I was getting a direct signal and not a reflection off a wall.
I’m kind of a Linux noob but I found LXC to be much easier to manage than Docker. Some nice resources are TurnKeyLinux images and the helper scripts:
