Line 2238 Unix V6 Comment: You are not expected to understand this.

Here is the famous line 2238 of Unix V6 which is part of some of the most delicate parts of the kernel, context switching.

This comment received huge publicity and just may be the the most famous source code comment in computing history.

Code:
2230	/*
2231	 * If the new process paused because it was
2232	 * swapped out, set the stack level to the last call
3333	 * to savu(u_ssav).  This means that the return
2235	 * actually returns from the last routine which did
2236	 * the savu.
2237	 *
2238	 * You are not expected to understand this.
2239	 */
2240	if(rp->p_flag&SSWAP) {
2241		rp->p_flag =& ~SSWAP;
2242		aretu(u.u_ssav);
2243	}

NAME
Jifty::Plugin::Comment::Notification::CommentPublished - new comments made SYNOPSIS
To activate this notification, you must override the notification in your application. use strict; use warnings; package MyApp::Notification::CommentPublished; use base qw/ Jifty::Plugin::Comment::Notification::CommentPublished /; sub setup { my $self = shift; # Send to the author of the post $self->to_list($self->parent->author); $self->SUPER::setup(@_); } sub url { my $self = shift; return Jifty->config->framework('Web')->{'BaseURL'} . $self->parent->permalink . '#comment-'.$self->comment->id; } 1; DESCRIPTION
This notification (when properly configured) is sent out to any who need to know when a comment has been published. METHODS
setup This method sets up the notification. This method should be overridden to setup "to_list" in Jifty::Notification to select who will receive this message. See the "SYNOPSIS". comment This will contain the Jifty::Plugin::Comment::Model::Comment that has been published. parent This will contain the object that the comment has been attached to. url This returns the URL that the message will link to. This should be overridden to provide application-specific URLs. The default implementation returns the BaseURL setting for the application. SEE ALSO
