too many open files, Ubuntu has default /proc/sys/fs/file-max of 1024.

It's an SA problem, not dev problem.

A couple guys at DEF CON this past year brought a coin-operated Bitcoin converter -- US currency goes in, QR codes full of crypto come out.

I'm holding onto my souvenir bitcoin (worth $0.25 at time of transaction) as long as I can.

This error isn't from node rather the OS has a limit on the number of files than can be open at once. The same limit would apply for another language/stack

If SA and dev had a great cooperation from an early point, the developer would have told the SA about the platform requirements.

I live a block away from this machine and won't be using it because of nonsense biometric data harvesting. Why do I need to scan my ID, picture and fingerprints to trade a small amount of bitcoins? I will continue to use the Russian guy who hangs out at a Robson St cafe and doesn't want my biometric data.

You don't, this one just scans your palm, which seems a lot easier than the runaround necessary to create an online account anywhere.

Since there are no 'palm databases' linking your palm to your identity, seems pretty anonymous too. It is only to ostensibly prevent any one user from going over the daily transaction limit. (As an aside I personally don't see anonymity as a big issue most of the time anyway).
