Ask HN: What Underrated Open Source Project Deserves More Recognition?
"OpenRefine is a powerful free, open source tool for working with messy data: cleaning it; transforming it from one format into another; and extending it with web services and external data." https://openrefine.org/

What you need to know about the future of Mozilla Hubs
Yes, let's hope! The strategy has worked out sometimes - Google shut down 'Google Refine' 10 years ago, it got turned into 'Open Refine', last update 2 months ago. https://github.com/OpenRefine/OpenRefine
It's a hugely useful tool if you're working with messy Excel-scale data, i.e., most biologists or social scientists.

UIUC MCS - CS 513 Review - Theory and Practice of Data Cleaning
There were six homework assignments. In order they were Regular Expressions, OpenRefine, Datalog, SQL, Provenance, and Python. None of these assignments took more than two to three hours to complete. They all were basic implementation and programming assignments with autograders.

Looking for: library to turn SQL (or abstracted) to code & execute against custom backend (slice of structs)
It seems that you're looking for something like https://github.com/npgall/cqengine but unfortunately I'm not aware of any equivalent in Go. LINQ is similar. I'd probably try searching for "LINQ in go" or something like that.

Evaluating Range Predicates over Java collections
I wonder if there's a huge difference in efficiency between RoaringBitmap and CQEngine. I used CQEngine a few years back and it turned out really great. Never tried RoaringBitmap, though.
