Anyone know what real time means here? Does it mean that sleeping a thread is more accurate (as in the thread is resumed at the correct time after calling sleep)? Or is there an API that implements some functionality for something that should run in real time?
I fail to see why this is bad advice. Sure you could just disable the firewall on your computer on a local network. But that’s under the assumption that you can trust everything on your local network. What if it’s a laptop? Do you also trust any public networks you may connect to on the go? Having firewall both on the router and on your computer provides an additional layer of security, and I think that’s good advice in general. You can for example set it up to only allow incoming connections when connected to your home network for example.
