What is the weirdest or most interesting piece of code you ever had to write?
Wrote the code to convert CQEngineCQEngine queries into Solr search queries.

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.

How to write unit tests in C++ relying on non-code files?
Java has in-memory file systems that are essentially geared for this exact use case, eg jimfs[0]. You create your filesystem and any files you need when your tests are starting up, and your classes talk to them rather than the “real” ones. Maybe a similar project exists for the C++ ecosystem?

Any library you would like to recommend to others as it helps you a lot? For me, mapstruct is one of them. Hopefully I would hear some other nice libraries I never try.
Recently been using JIMFS. Made my tests much faster and cleaner!

Working and unit testing with temporary files in Java
I use Google's JIMFS "Just In Memory Filesystem" https://github.com/google/jimfs in my unit tests and have been very happy. No need to clean something up that disappears as soon as the test is over. Let's you create unix or windows style filesystems and I've used it to test a disk space healthcheck because you can set a limit to the size of the filesystem it creates. Very flexible and easy to use.
