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.

Understanding Photo Stacking
Without a tracking mount you can use this calculator to determine what exposure time you can get away with without significant trailing. It depends heavily on the declination (basically the arc length between the north pole and the object you are pointed at), lens focal length, and pixel size of your camera.

Milkyway panorama with Zodiacal light, Captured from Vattakanal, Tamilnadu.
This was a 14mm lens, most will say use 500 rule but I suggest you to use NPF rule if you want pinpoint stars(or it will have an option like slight trailing this is what I used) it showed 12 seconds I think, I went a bit over since I know 14mm is pretty wide and you can't see any trailing once it is wide
- Here's a list of all the fastest lenses ever made, by format and focal length
- M31 135mm?

1 vs 2500: I couldn't afford an expensive Telescope or a Star Tracker so I took over 2500 shots of the Orion Nebula from a pretty light polluted city in Central India with just an entry level DSLR. Combined them together using a method called "Stacking", and this was the result [OC]
That method isn't that accurate anymore(some people use 400 or even 300 rule), but these days the recommended method is The NPF rule.

Don't have an expensive Telescope or a Star Tracker? No problem. I couldn't afford them either so I took over 2500 shots of the Orion Nebula from a pretty light polluted city in India with just an entry level DSLR. Combined them together using a method called "Stacking", & this was the result [OC]
4) How to select your exposure length: If you take long duration exposures (let's say) 15-20s or something, what you will see are star trails where instead of pin pointed stars, you'd see them moving in a line, ruining our shot. To get sharper stars, either use the rule of 500 (beginner friendly) or the NPF rule (more accurate, but a bit more advanced). Make sure you take a few test shots, zoom in and check the focus and star trailing first before continuing.

Please tell me if I’m doing anything wrong with my AP process.
I've made a Calculator some time ago that can help you decide on the expose times without a tracking mount. It might be usefull: https://calc.loef.photos/

What are the best settings to take a picture with a Canon EOS RP with a 50mm RF lenses?
Seeing might have also been just not good enough. I saw an app called nightshift. Pretty good indications of how clear the sky is actually. Also, indeed have a look at the 'rules'. 500 rule might be a bit too crude. Suggest to check your camera and lens specs and fill them in at: https://calc.loef.photos/

How to convince the wife that the server rack isn't the root cause of our power bill: with data!
I run Plex, 3 instances of photo-stream, a couple HomeKit related automations, librespeed, an api for my lametric clock, and a few really simple web pages like a darts scoreboard and a weather page.

Docker c’est un système pour faire des containers (une sorte de virtualisation mais plus simple qu’une vm) et le Dockerfile ce sont les instructions pour construire ce container (ici on part d’un container avec ruby installé, on télécharge vips, on le compile, on copie le contenu du dossier d’où tu le lance dans le containers, on va dans ce dossier, on installe bunder, jekyll et les dépendances de photo-stream, on expose le port 4000 pour jekyll et on lance jekyll). Même sans utiliser docker un Dockerfile peut être une bonne indication des commandes à faire pour installer un truc.
