ssh-copy-id -i my.key.pub <hostname probably from tailscale>
this makes sure I can run ansible from my desktop against VMs on my server
easily if they have tailscale for the hostname - otherwise use the IP

Nextcloud Docker Upgrade Error
https://nicolasbouliane.com/blog/nextcloud-docker-upgrade-error
in /lib/systemd/system/docker.service there is an ExecStart command that got placed there when I setup Docker with Ansible - it threw the -H flag which told the daemon what hosts to setup. But I added the “hosts” key in my daemon.json and it broke - so removing the -H flag from the systemd unit fixed it
I regularly need to edit system config files - take /etc/sanoid/sanoid.conf as
an example… I’ll want to play with something but if I don’t start Neovim as
root then I get in trouble making edits I can’t save! So
suda.vim gives me

I’m Neovim is running with my login user!
I’m playing with my ansible playbook in a remote tmux session, and I’m no wiz

ansible-playbook plays.yml -v --tags mytag | less
Description of my proposed vimconf 2022 talk
Switching to Vim opened a whole new world to me for interacting with a computer and for getting things done. Before I adopted Vim I used GUIs for everything because I thought that’s how it had to be done… Notes in OneNote, code using a GUI editor, different notes in TiddlyWiki, slides for work in PowerPoint, slides for church using Logos, etc… Adopting Vim allowed me to disconnect a specific tool from the problem that tool is solving - because usually I just need to write text (notes, code, slides, etc.). Now, very nearly everything I do is from a text-based and git-based workflow… I put all my notes on basically anything just in my blog, which is all markdown and deployed to GH with Markata on every push (living dangerously pushing to main) - and that’s all done easily from Vim with nice syntax highlighting, fast response, integrated git-plugins, etc.. I keep project-specific task lists just in markdown files and I have Vim/tmux shortcuts to quickly add todos for any project (todo lis…
mkdir s{1..10} will make directories s1, s2, … s10 in one command!
Bought some DDR4-3600 speed RAM but only seeing 2666? Load up the BIOS, find DRAM config or something similar, and make sure to load the XMP profile to get that advertised RAM speed!

THen we can look at print outs
cat /var/log/auth.log also showed me that I had too wide permissions on files in ~/.ssh -> probably changed from an rsync job
