in reply to du -h, sorted

I can't stop looking at this unbeliev unbellairevable one-liner! Alas, in your Update, you went from 7**(ord$&&30) to 99**(ord$&&7), and the new one mis-sorts empty files.

And I can eke out one last character in a reversed sort:

perl -e '%h=map{/.\s/;7x(ord$&&10)+$`,$_}`du -h`;die@h{sort%h}'

[Corion]: Meh. My bank removed (part of) their CSV download facilities. Now I will either have to implement a full scraper or automate the download using the HBCI interface instead (or just get a new account elsewhere...)
[Corion]: On the upside, I spend a lot of time thinking this weekend about how to actually implement rate limiting for futures, and if things work out, maybe even loading a configuration from an external file makes sense
[Corion]: I've also found some interesting invariants that I have to think/write about more. A simple rate limiter will never change the order of the input, while a limiter that allows for parallel execution will change the order. But my API currently allows for bo
[Corion]: ... for both, and I'm not sure if I want to add the cruft from the parallel API (a token that you need to hold on to while you hold the lock) to the rate limiting API too, to allow seamless up/downgrades, or not.
[Corion]: Also, rate limiting will look great with await: my $token = await $limiter-> limit($hostname); instead of my $f = $limiter->limit( $hostname )->then(sub { my( $token)=@_; ... });
