There is definitely a shift away from traditional VPNs these days since VPN tunnels tend to be more open and permissive. You can obviously secure a tunnel and limit network access, but you are still directly accessing the networks and resources that you do allow, remotely.

I was running Kasm for a while and I really liked this approach to secure remote access. I could effectively spin up a Ubuntu docker image and access it remotely through the browser. Secured the web portal with my IdP which requires MFA and I would login remotely and launch various apps and desktops.

They are non persistent in nature, so once you log off and destroy the instance you would effectively get a new desktop the next login.

Generally works pretty well

His point was that bittorrent wasn’t around in the 90s

Very flexible in terms of what it supports. Somewhat difficult to assemble (maybe they fixed that in the latest release). Works pretty well. But honestly it’s going to depend on what printer you are using it on. When I did it on the ender 3 it didn’t really make a big difference, that printer is slow and additional cooling wasn’t needed. If you are printing filaments that benefit from lots of cooling and are printing fast it can be helpful to get multiple 5015 fans running.

One nice thing is that you can choose some fans that are bigger (4020 and 5020) and run them at lower speeds to reduce noise.
