Talk:Hourglass puzzle

task wording

The term   hourglass   is a device used to measure one hour.

The generic term for such a device is a   sandglass,   which can measure specific times   (set/defined during manufacture);   usually filled with a fine (dry) sand,   pouring/running (by gravity) from one vessel to another.     -- Gerard Schildberger (talk) 04:14, 30 December 2020 (UTC)

I missed that it says hourglass but times in minutes. You could use sandglass and keep the minutes or keep hourglass and change the units to hours.

I'm sure you're right, though Collins, alone I might add, disagrees with British English "a specified time" and American "esp. one hour" --Pete Lomax (talk)

task name

Perhaps the Rosetta Code (draft) task should be renamed to Sandglass puzzle.   It may be more descriptive,   but many people generically call a sandglass an hourglass,   where the latter is more well known,   even though most sandglasses are used to time boiling eggs   (a three minute egg timer)   or as a game timer for a player to solve or provide an answer.     -- Gerard Schildberger (talk) 04:35, 30 December 2020 (UTC)

Interim flips

Quite a fun little challenge.
At heart, of course, it is really just a straightforward breadth-first search.
Interm (and deferred) flips are/were allowed in the initial Logo submission. --Pete Lomax (talk) 17:35, 30 December 2020 (UTC)

Very nice solution indeed

I was late to see yours and then made a wrong reference to Julia instead .. --Hkdtam (talk) 17:48, 30 December 2020 (UTC)
