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.

Graphviz: Open-source graph visualization software
A fast 3D alternative for visualizing large graphs is Graphia: https://github.com/graphia-app/graphia https://graphia.app However, it's currently suffering from the Qt switch from 5 to 6.
Regarding Graphviz itself, I wonder why is there no special layout logic for planar graphs? They can be recognized and embedded on the plane in linear time without intersecting edges, so it would be very nice if some of the Graphviz tools actually did that.

Fcron Is the Best Cron
I was annoyed by cron/fcron limitations and figured systemd is the way go because of its flexibility and power, but also was annoyed about manually managing tons of unit files. So I wrote a tool with a config that looks kinda like a crontab, but uses systemd (or launchd on mac) behind the scenes: https://github.com/karlicoss/dron#what-does-it-do
E.g. a simplest job definition looks like this
job(every(mins=10), 'ping https://beepb00p.xyz', unit_name='ping-beepb00p')

Ask HN: Share Your Personal Site
https://beepb00p.xyz I mostly write about data liberation, quantified self and knowledge management.
Some notable links:
https://beepb00p.xyz/myinfra.html -- map of my personal data infrastructure (usually people say I'm a bit mad after seeing this :) )
https://beepb00p.xyz/blog-graph.html -- a nice visual way to explore my posts
https://beepb00p.xyz/exobrain -- my "external brain", basically public notes/links dump

Graphviz: Open-source graph visualization software
Graphviz is awesome!
Here are a couple of my diagrams:
https://beepb00p.xyz/blog-graph.html -- graph of my blog pages with tags/connections between posts, generated with a DSL-ish python script https://github.com/karlicoss/beepb00p/blob/master/misc/index...
https://beepb00p.xyz/myinfra.html -- map of my personal data & infrastructure (discussed a year ago https://news.ycombinator.com/item?id=26269832 ). Also a similar DSL https://github.com/karlicoss/myinfra/blob/master/generate.py
The main downside for me is that sometimes it gets the positioning wrong, and you can see how it can be easily fixed, but it's hard to convince graphviz to actually do so. Basically I'd love a tool where I can do 10% of positioning manually and let the rest be constraint based like in graphviz.
