 Fell asleep around 1 and woke up around 6:30. As yesterday, had breakfast at 7 but then played piano. The upgrade was still not completed, because I forgot to add a pve apt source. While upgrading proxmox, read some codes of projects like faas and js online playground, I wanted to know how to run js code safely at runtime. After proxmox had been upgraded, tried to setup cloudinit template using the latest LTS version of ubuntu. Then created two vms. I suppose I only needed three vms, one for networks related, pi-hole/adguard, wireguard/tailscale, and clash etc; one for console. including vault server so I can connect to proxmox vms as well as aws/aliyun servers, now I feel it might be unnecessary; and the last one for running docker images. No cluster, so no needed to worry about network problems I mentioned before, and it was simpler to set up. I created vms for the latter two, named Turo (from Turo Asakura) and Roger respectively. Played Zelda after lunch, and returned to my study room to work on my home lab. Took part in an English lesson at 4. Took a nap after dinner, then did the running exercise around 10. Fried some chicken legs, I would eat them with Qingdao white beer. Completed 15 pomodoroes today - one for learning, two each for English and exercise, and five each for research and work. It seems to be rainy tomorrow, but I will go out as long as the rain doesn't last long.
