This is getting silly. Please make sure to use anything you may have
been given to do your work, by order of usefulness:

- brain,
- documentation,
- computer.

You obviously have a computer, so, if you are missing any other item
from this list, please make sure to get the complete package before
posting anew.

Also, please stop posting whatever code you happen to perpetrate to this
list: it gives anyone with a functional brain a huge feeling of
seasickness.

Final note: this list is not a cheap helpdesk to get his work done for
free. Everyone has to do some efforts to keep things rolling.

Thanks (I'm trying hard to mean it).
