I wasn't able to find any up-to-date information about tail call optimization support in Ruby, so I decided to post this hoping that it will pop up next time someone might also be searching for this topic...

What I was able to figure out is that TCO can be enabled in Ruby 3.4 via a compile option like so:

RubyVM::InstructionSequence.compile_option = {tailcall_optimization: true}

def tailSumUntil(n, m)
  n == 0 ? m : tailSumUntil(n - 1, n + m)
end

tailSumUntil(100_000_000, 0)
# => 5000000050000000

I remember that way back around 2015 the double XP boost used to stack, so you could get a 4x multiplier, but I don't think that I've ever got a triple.

It seems that they have accidentally posted the announcement earlier than intended, but it will probably show up later during the day.

There are plenty of utilities (GUI, such as filelight and TUI, such as dua as well) for analyzing disk usage by space, but I would like to view my folders based on the count of files, as I'm making backups, and folders with lots of small files (e.g. node_modules) take very long to move around, so I guess that I'd be better of compressing those into a single file before archiving, as it's already highly unlikely that I'll need to access them anyway. Thanks for any pointers in advance!

If the rolling wooden variant still turns out not to be enough, I might need to source a real live duck. 🦆 Not sure how patient that would be at listening to me explaining code though. 🤔
