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.

Updating data files, commits vs. pull requests
My Jet Train project makes use of GTFS. GTFS stands for General Transit Feed Specification. It models public transportation schedules and their associated geographic information.

An example of overengineering - keep it WET
I had to rewrite my Jet Train demo to use another data provider, switching from a Swiss one to a Bay Area one. One of the main components of the demo is a streaming pipeline. The pipeline:

"Once you see the world in terms of data and events, your imagination is the limit!" — Nicolas Frankel.
My favorite project at the moment is Jet Trains, even if right now it has nothing to do with trains. When I joined Hazelcast, my colleague Neil Stevenson showed me a demo project of his. He had recorded the position of the train he was riding on in Italy some time ago and he had used Jet to display the position on the map. I felt it had a lot of unused potentials: the position markers were never removed, there was a single train, etc. So I thought about displaying many trains on the map and moving them "in real-time" (or close to, as there's no such thing as real-time).

Reverse ETL recommendations?
Reverse ETL is on AirByte's roadmap under the "Future / Not prioritized" section. I wanted to use Grouparoo as a short term solution, but the repo was archived and I think they stopped taking new cloud customers (unknown if this is wrong/outdated).

Reference Data Stack for Data-Driven Startups
There are other tools that we will have to adopt in the future but haven’t yet due to lack of necessity. Specifically, one category that is popular in modern data stacks is Reverse ETL (Hightouch, Census, or Grouparoo). We currently don’t have a usecase for piping data back into 3rd party tools but it will definitely come up in the future.

Is Reverse ETL a new product or a new ETL/ELT feature?
Grouparoo, the open source Reverse ETL tool we are building, does all of these things. https://www.grouparoo.com

Launch HN: Hightouch (YC S19) – Sync data from data warehouses to SaaS tools
Congrats on the launch! Hightouch looks great and this need is real. Things seem to be going well, so I don't think I'm taking too much away by mentioning that we have been been working on Grouparoo, an open source alternative that solves similar pain points.
A few differences: git developer workflow focused (branches, CI, PRs, etc), ability to self host, segmentation in destinations (tagging people in mailchimp based on rules, for example)

Reverse ETL
We are building Grouparoo. Obviously, it's a biased sample but we are seeing a few trends at play.
