golink VS bitbar

Something else interesting they're doing is their tsnet package, which lets you join your process to the tailnet and bind tcp listeners/connect to TCP services via their tailnet IP or subnet.

I'm writing some stuff using this at the moment, but I also just saw https://github.com/tailscale/golink which does the same thing: a single binary that runs a link shortener that joins itself to your tailnet.

tl;dr: don't run your service on a machine then join that to tailnet, directly bind your service to an in-memory tailnet client

While no broken out per plug, APC UPS network management cards provide total power output data (current, voltage, frequency, power) via SNMP, which you can log using a wide variety of tools.

And even without external tools, historical power usage logs are available via the APC Web UI.

While I don't currently log anything externally, I use an xbar[1] script[2] to display UPS output current in my Mac menu bar.

5. Download and install xbar https://github.com/matryer/xbar

Maybe with https://xbarapp.com/ ?

Maybe with xhttps://xbarapp.com/bar? You can also take a look here.

Maybe you can use AnyBar https://github.com/tonsky/AnyBar/ or xbar https://xbarapp.com/

xbar (Free) xbar is free and open source it allows you to put anything in your macOS menu bar, although the learning cure is high, I would put this in development too..
