I started thinking about when we should adapt #curl's progress meters to deal with > 63 bit download sizes (8192 Petabytes).
I'm thinking it might not be terribly far away when people can start downloading that. In particular when doing N super huge transfers in parallel.
Got me thinking about 128 bit math...

in reply to daniel:// stenberg:// • • •128-bit math is ... tricky. We implemented a 128-bit type for n-dimensional arrays to represent images in our #ImgLib2 library for image processing. So many gotchas in defining basic arithmetic operations; at some point in version history all our custom implementations were replaced by java's BigInteger's.

Our motivating use case? Integral images (summed-area table: en.wikipedia.org/wiki/Summed-a… ). But now the 128-bit type has found other uses too.

in reply to daniel:// stenberg:// • • •Hm. I could see a (very limited) practical use case for this from around 2040-2050 then, like "consolidate the 20 ZB of old data from 2030-2033 to cold storage to make room for new stuff on the active storage near computing".
And while a single curl command is not the most likely tool choice, it would be neat if it was viable.
