Show HN: Marple – Interactive time series visualization for engineers 4 by NeroVanbierv | 0 comments on Hacker News. Hi HN, excited to share the project I have been working on for the past two years. Marple was created by engineers for engineers. Marple helps them organize and analyze their sensor data in a more user-friendly way. We’ve all been there: measurement data from an experiment or test needs to be analyzed but the only thing you have is a few data files flying around. You do not have a clue how to open or read the data. So what you do next is open your Python/Matlab/Jupyter Notebook/… and start coding in order to make some sense of the data. We didn’t like that process, so we started Marple to solve this issue. Engineers tend to log data at frequencies from 1Hz to 10kHz and usually log hundreds of sensors at the same time. Data sets usually contain millions of data points. In order to make our web-based data visualization responsive, we had some technical challenges to tac...

Ask HN: How to keep water-obsessed autistic child from wasting water 12 by bryanrasmussen | 22 comments on Hacker News. I have a child with autism, who has developed a fascination with the bath and running the water. If we stop him he of course has a meltdown, so what I am looking for is a method for controlling the water easily from another point than the faucet. I guess a plumber can set me up something like that, but I also wanted to see if anyone had suggestions. Also was wondering if anyone had suggestions for setting up a recycled tub, that is to say the water can be set to run back after running out, so that it does not cost excessive amounts.
