For those interested in FS and open source today, especially through a capital markets lens check out:
Lots of great projects, one I used recently and a favourite was this:
Perspective was, in a previous life, a proprietary internal engine for Python/desktop applications at JPMC, that was ported and open-sourced to FINOS as a web assembly based browser component. Open sourcing perspective had a huge impact on the project, not just from the awesome community contributions and engagement and support from FINOS itself, but (as a huge surprise to me) the perspective project's visibility within our company.
I think I am in love :-) This is what WebAssembly is supposed to for! Could it easily find the "how to contribute" if there is one please point me at it :-)
I contrast that with the Moov.io repos (full disclosure, I'm familiar with them though I haven't contributed), and they're actually nitty gritty details of dealing with the banking system (at least in the US), things like processing ACH files, wires, ISO 8583 (card network) messages, Image Cash Letter, watchlists needed for KYC and OFAC checks, etc.: https://github.com/moov-io
TBH it just sounds like a very apples-to-oranges comparison.
