I use apt cacher ng. Most of my use case though is for caching of packages related to Docker image builds as I build up to 200+ images daily. In reality, I have aggressive image caching so I don’t actually build anywhere close to that many each day but the stats are impressive. 8.1 GB of data fetched from the internet but 108 GB served from the acng instance as it shows in the stats page of recent history.
I have two internet connections - one is fiber and the other is cable. My cable is the backup connection and is a lower tier offering with a 1.2 TB/month cap while my primary fiber is 1gig symmetrical with no data cap. I use pfsense to handle failover in case of an outage.
I also use acme.sh. It has worked great for me and was dead simple to use. Super flexible on what it can do from just renewing the certs to web server integration. Love the simple to use hooks available too.
Check out Plexamp, the Plex music streaming client.
I user homer. Really simple, basic config and it looks nice. The stats are pretty cool for certain integrations and are easy to add - I’ve added a few myself for services that didn’t have them. Only issue is slow PR review.
I would also second Hugo which I use for my personal site and blog which I haven’t updated for a long time. Nice thing is that it has a minimal footprint of needing to watch out for updates unlike something like Wordpress which was known for being vulnerable stable if left unmaintained. It’s mostly looking out for old themes with vulnerable javascript.
Another popular options is Jekyll and I honestly can’t remember why I picked Hugo over it but if you don’t need dynamic content, why make things more complex?
