Lit: fish timber question answer.
The dialog is also known as allegory for an incredibly deep philosophical discussion between an idealized wise woodcutter and a fisherman, e.g. mentioned at: www2.kenyon.edu/Depts/Religion/Fac/Adler/Writings/Fisherman%20and%20Woodcutter.pdf
This song is just too slow for Ciro Santilli to make much out of it.

Authentication (cryptography) Updated 2025-07-16
In the context of cryptography, authentication means "ensuring that the message you got comes from who you think it did".
Authentication is one of the hardest parts of cryptography, because the only truly secure way to do it is by driving to the other party yourself to establish a pre-shared key so you can do message authentication code. Or to share your public key with them if you are satisfied with the safety of post-quantum cryptography.

AGI-complete in general? Obviously. But still, a lot can be done. See e.g.:
Available battery voltages Updated 2025-07-16
Only certain battery voltages exist, because this voltage depends intrinsically on the battery's chemical composition.
learn.sparkfun.com/tutorials/battery-technologies/all (CC BY-SA) has a very good summary list, reordered from lowest to highest voltage:

Since Snakes and Ladders is nothing but a Absorbing Markov chain, the results are exactly the same as for that general problem.

Whichever problem you present a German, they will look for a mechanical solution to it!
These come with pre-installed drivers, so e.g. nvidia-smi just works on them out of the box, tested on g5.xlarge which has an Nvidia A10G GPU. Good choice as a starting point for deep learning experiments.
