after spotting a mistake in a very old answer, should I add the correction as an "EDIT: explains mistake here" or should I just edit the whole answer and fix it?

@Seth should I at least write a note about the edit, since some comments will stop making sense after it?

it's an answer about how fork bombs works, and I wrote an answer with the wrong assumption that a function running a command in the background would wait it to return before stopping, so :(){ : &};: isn't really a fork bomb..

A: How exactly does the typical shell "fork bomb" call itself twice?

Piping doesn't require that the first instance finishes before the other one starts. Actually, all it is really doing is redirecting the stdout of the first instance to the stdin of the second one, so they can be running simultaneously (as they have to for the fork bomb to work). Well, What e...

just fixed it, think it's too confusing @Seth?

How can I placed my answer at the top of the question? Edit the post will do it?

Eliah Kagan

@Benny You basically can't. Editing a question or any of its answers bumps it on the front page of the site, but that doesn't change the order in which answers appears on the question itself.

The default ordering of answers on a question is by votes, which means that posts with higher score (upvotes minus downvotes) appear higher and posts with the same score appear in a randomized order with respect to one another, but if the OP has accepted an answer that another user wrote, then that appears at the top regardless of it score. The system lets users select two other orderings -- active and oldest -- but the votes ordering is the one that is in use by default.

With the active ordering, editing an answer will cause it to appear the the top. You should not edit your answers with no reason just to make that happen, though (and anyway, most people don't use the active ordering). With the oldest ordering, answers that were posted earlier will appear before answers that were posted later.

@EliahKagan Do you ever sleep?

:-)

Eliah Kagan

Yes, I sometimes sleep. :)

Those active oldest votes "tabs" appear on each question page, before the answers.

Thanks @EliahKagan

share with you the post I was talking about:

A: How to install updates via command line?

Execute all the commands by typing sudo once: sudo -- sh -c 'apt-get update; apt-get upgrade -y; apt-get dist-upgrade -y; apt-get autoremove -y; apt-get autoclean -y' or sudo -s -- <<EOF apt-get update apt-get upgrade -y apt-get dist-upgrade -y apt-get autoremove -y apt-get autoclean -y EOF

Thought you guys would get a kick out of it.

Seth

@RobotHumans Pretty accurate. They just forgot the 10 cameras pointing at you from all sides with Windows 10

RobotHumans

@Seth That's why it's windows 10 instead of windows X. 10 cameras installed by cortana.
