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.

Ask HN: Did you change your software architecture due to monetary constraints?
At the start up I work at [0], we use an open source library I developed to run hydraulic models of water networks in JavaScript [1].
A hydraulic model may be between 1-10MB and the simulation results can end up being 100+MB of time series data.
Other vendors with proprietary engines have to scale up servers to run their simulation engineers and will store and serve up results from a database.
Having everything done locally means we only have to store a static file and offload the simulation to the client.
Because we've architected it this way our hosting costs are low and users generally have faster access to results (assuming they're running a moderately decent machine)

Ask HN: How did you find your current job?
I'm a civil engineer and I wrote an open source library that compiled a C library to javascript for my own personal projects - epanet-js [1]
A water utility in Spain spun off a start up called Qatium [2] and they used my library as the engine of their simulations and asked me to join.

Ask HN: Which personal projects got you hired?
I created a handful of application around water engineering/modelling [1], plus an open source library to run the simulations in javascript [2].
A water utility in Spain spun off a start up to create a similar web based water modelling application and they used my open source library.
They approached me and I joined them and have been able to maintain the open source library as part of my role.

Ask HN: Have you created programs for only your personal use?
I work as a water engineer, specializing in building hydraulic models so water utilities can simulate their network.
A big part of that is calibrating them which can be time consuming, you look through hundreds of options. I create a few web based apps to help grind through these tasks but ultimately they were for my own use as a consultant to close projects quickly.
I did pull out the engine as its own open source library for other to use, and that ended up helping me get my current role where I can now maintain it and be paid at the same time.

Ask HN: What is your current side-project?
https://github.com/modelcreate/epanet-js
I've built a few open source apps and few other little projects to help automate my workflow.
There are only a handful of providers of modelling software, most are commercial and one recently sold to Autodesk for $1B.
Not sure I'll convince the industry to change but I'm enjoying tinkering around and making my own small difference.
