+2024-01-21: You can inject HTML and CSS to gitweb without modifying the default files by using $home_text and pointing it to a variable, and push @stylesheets.
+2024-01-20: App groups can let you share application data, but they will create a new container, so unless you have a remote data source it will erase your data. It's better to start new mac or ios projects with a group
+2024-01-19: You can rename the classes in xcdatamodel in order to avoid collisions, in case you named an entity something too generic.
 2024-01-18: MacPPP with modem initialization options works much better than ZTerm + FreePPP, and allows 115200 baud. You just have to set the modem to initialize with AT, and then dial PPP.
 2024-01-17: Mastodon will NOT auto-clean the media directory, which can quickly bubble in size, and you can't ask sidekiq to deal with this so you need to set a cron job. A systemd.timer can handle both cases.
 2024-01-16: With dnsmasq + tailscale you can easily combine your home lab with a remote server and make management a lot easier without exposing some services to the web. A local dnsmasq running on raspberry pi can make sure all local services have a nice name, and then can point an internal url to the vps. In firewalld you need to block connections unless they come from your 100.0.0.0/8 block.
