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.

ePaper-Weather: My own build of a weather monitoring display for my personal needs
Additionally, because I love building up data infrastructure, I've added a Grafana instance backed by an InfluxDB. I've tried TickTock instead of InfluxDB because I was afraid of performance issues on a Raspy, but I had stability issues with TickTock. Also InfluxDB doesn't seem to cause memory or CPU issues.

Help with timeseries data
TickTockDB is a new open-src TSDB. Although it is not rich in features, its write throughput can reach 3.2M data points/sec v.s. InfluxDB 74K in a 2c4g x86 (detail report here). It is enough for your case (79M data point/day = 914/sec). You may also have to consider max cardinality (i.e., number of time series supported) of TSDB. TickTockDB's max cardinality is 2M v.s. InfluxDB 150k in RaspberryPI4 (detail report here)).

Building a faster hash table for high performance SQL joins
Looks like full keys are always compared if hash codes test equal, which is what I'd expect. For example: https://github.com/questdb/questdb/blob/master/core/src/main...

K3s Traefik Ingress - configured for your homelab!
But of course, I want to run a QuestDB instance on my node, which uses two additional TCP ports for Influx Line Protocol (ILP) and Pgwire communication with the database. So how can I expose these extra ports on my node and route traffic to the QuestDB container running inside of k3s?

Annotations in Kubernetes Operator Design
In this post, I will detail a way in which I recently used annotations while writing an operator for my company's product, QuestDB. Hopefully this will give you an idea of how you can incorporate annotations into your own operators to harness their full potential.
