Docker Container for phpMyAdmin
Been containerizing a lot of my tools and just added phpMyAdmin to that list. It’s very easy to get going with it esp. if you also happen to have a Docker container running MySQL albeit with one minor issue.

Installing Smart Water Shut Off Valve
I took my smart home journey one step further today. I installed a smart auto water shutoff valve. Wow, what’s that? Well, this device mounts to your main water shutoff valve and automatically open or close it based on your command. Sounds magic! Yes it’s magic.

Fixing Random Samba Share Lockouts Part 2 w/Docker
Continuation of my previous post about fixing random Samba Share lockouts. I discovered that Docker and Samba were fighting to gain access to the folders. If I set the label to samba_share_t, then Docker loses access. If I allow Docker (with “Z” option while running container), then Docker resets the label to “svirt_sandbox_file_t”.

That printer does not have Wireless printing feature and I wanted to have all computers in the house be able to use it over the network.
