<blockquote>The technological singularity is a hypothetical event in which artificial general intelligence (constituting, for example, intelligent computers, computer networks, or robots) would be capable of recursive self-improvement (progressively redesigning itself), or of autonomously building ever smarter and more powerful machines than itself, up to the point of a runaway effect—an intelligence explosion—that yields an intelligence surpassing all current human control or understanding. Because the capabilities of such a superintelligence may be impossible for a human to comprehend, the technological singularity is the point beyond which events may become unpredictable or even unfathomable to human intelligence. <ref>https://en.wikipedia.org/wiki/Technological_singularity</ref></blockquote>

Talk:149: Sandwich

198.41.235.35: add Siri easter egg.

Note that it is more effective to write "sudo !!" to redo the last command but with sudo added to it. {{unsigned|Agge.se}}

:Using <code>sudo !!</code> outputs the previous command with sudo into your bash (other shells as well) history, so to bash what you said was "sudo make me a sandwich" not "sudo !!". [[User:Lcarsos|lcarsos]] ([[User talk:Lcarsos|talk]]) 16:46, 29 October 2012 (UTC)

<code>sudo</code> requires '''user''' password, not admin password, but you need to be in <code>sudoers</code> file. --[[User:JakubNarebski|JakubNarebski]] ([[User talk:JakubNarebski|talk]]) 12:14, 15 December 2012 (UTC)

:How many people will know the difference? In a typical Ubuntu-family install with only one human user, root doesn't ''have'' a password, but the one user who does is a sudoer (and has to use <code>sudo</code> or <code>su</code> to act as root, rather than doing so starting at login).

"the user first must type their password" This is not accurate. It is the default, but many domains disable that requirement.

I believe the original comic actually read "Sudo bang bang" instead of "Sudo make me a sandwich". Here's a link to what I think is a copy of the [http://stackoverflow.com/questions/15137461/what-is-sudo-bang-bang original]. I'm not sure which of the two is actually the original. {{unsigned ip|‎99.95.158.248}}
:The words "bang bang" (particularly the first B) look a bit fuzzy/pixelated compared to the rest of the text, which gives me the feeling that it was edited from this one, which is the original. [[User:Zowayix|Zowayix]] ([[User talk:Zowayix|talk]]) 23:03, 23 January 2014 (UTC)
::If you click on the image (on the Stack Overflow link), it leads you to http://justinsomnia.org/2006/09/sudo-bang-bang/, which says: 'This just occurred to me' [comic] 'Original comic from xkcd by Randall Munroe', implying it was indeed edited.

Comment: This conversation is an easter egg in Google Now on Android tablet. Using voice search to say "make me a sandwich" will give the reply "what? make it yourself", adding "sudo" will get the response "ok". I assume the Google now implementation came later and is based on xkcd. {{unsigned ip|141.101.99.27}}
:Siri will also respond "okay" if you say "sudo make me a sandwich:", though she doesn't respond with the XKCD response to "make me a sandwich". [[Special:Contributions/198.41.235.35|198.41.235.35]] 13:32, 27 October 2015 (UTC) (MSC)

This reworked for the Make utility:
<code><pre>
$ make sandwich
Must be root
$ sudo make sandwich
cc sandwich
mv sandwich /etc/sandwich
sandwich installed in /etc
$ _
</pre></code>

Talk:1553: Public Key

2015-07-20T04:59:55Z

198.41.235.35: Offered a basic explanation.

I'm assuming he's referring to the GPG/PGP Key. Basically you have a key pair, one private that you use to sign/encrypt and one public, which can be used to verify your private key was used to sign. See [https://en.wikipedia.org/wiki/Public-key_cryptography Wikipedia] for more information. If you posted your private key, anyone could sign as if they were you. I sign pretty much everything (not to mailing lists though), but don't think I've seen anyone else ever do so, even those I know have keys. See [[1181: PGP]] for more.
