Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Aider: AI pair programming in your terminal
Thanks for open sourcing this project! I've packaged it with nix to make it easier for others to use: https://github.com/nixvital/ml-pkgs/blob/main/pkgs/aider/def...
If you are running nixos, an example of using it can be found here: https://github.com/breakds/nixos-machines/blob/main/flake.ni...

Ask HN: How can a total beginner start with self-hosting
I have been there. The progress was rather slow until I started to use NixOS. The learning curve is a bit steep but is very rewarding. It is not specific to self-hosting stuff, but as a side effect it makes self hosting super easy (declarative, readable, etc).
For most of the services that you would like, you just write a simple configuration and deploy it. For example, to run the service shiori (https://github.com/breakds/nixos-machines/blob/main/machines...), or to host a game (terraria) server (https://github.com/breakds/nixos-machines/blob/main/machines...), or tailscale (https://github.com/breakds/nixos-machines/blob/main/base/tai...). Since Nix is also a very good package manager, you also do not have to deal with installing packages and managing their dependencies.
With my NixOS server I am running all the services you mentioned, and also my router is just a bunch of services running on a NixOS box.

Should I set up my own server?
- own server costs about $5/month. I recommend using docker to deploy hbbr and hbbs. Back up the key in case you need to re-deploy. You do need to secure your Linux server, and this community-driven Github guide has some good tips to get started.

Automating the security hardening of a Linux server
I have been using the How To Secure A Linux Server guide for quite a while and wanted to learn Ansible, so I created two playbooks to automate most of the guides content. The playbooks are still a work in progress.

Connecting to docker containers rarely work, including via Caddy (non docker) reverse proxy
If it works, I will then follow the hardening guide I did before (https://github.com/imthenachoman/How-To-Secure-A-Linux-Server) and test after every step

Resources to learn backend security from scratch
Maybe these two repos can help you, I've used them both from time to time to look up stuff I have no idea about as a frontend main: https://github.com/imthenachoman/How-To-Secure-A-Linux-Server https://github.com/decalage2/awesome-security-hardening

Ask HN: How can a total beginner start with self-hosting
> In short it’s all about control, privacy, and security, in that order.
I am going to strongly urge you to consider changing that order and move *security* to the first priority. I have long run my own servers, it is much easier to setup a server with strong security foundation, than to clean up afterwards.
As a beginner, you should stick to a well known and documented Linux server distribution such as Ubuntu Server LTS or Fedora. Only install the programs you need. Do not install a windowing system on it. Do everything for the server from the command line.
Here are a few blog posts I have bookmarked over the years that I think are geared to beginners:
"My First 5 Minutes On A Server; Or, Essential Security for Linux Servers": An quick walk through of how to do basic server security manually [1]. There was a good Hacker News discussion about this article, most of the response suggests using tools to automate these types of security tasks [2], however the short tutorial will teach you a great deal, and automation mostly only makes sense when you are deploying a number of similar servers. I definitely take a more manual hands-on approach to managing my personal servers compared to the ones I professionally deploy.
"How To Secure A Linux Server": An evolving how-to guide for securing a Linux server that, hopefully, also teaches you a little about security and why it matters. [3]
Both Linode[4] and Digital Ocean[5] have created good sets of Tutorials and documentation that are generally trustworthy and kept up-to-date
Good luck and have fun
