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)
