Quotes

A programmer is sent to the grocery store with instructions to "buy butter and see whether they have eggs, if they do, then buy 10." Returning with 10 butters, the programmer says, "they had eggs."

There are two ways to write error-free programs; only the third one works.

You can't make a program without broken egos.

Why did the programmer quit his job?

Because he didn't get arrays.

Programming is 10% science, 25% ingenuity and 65% getting the ingenuity to work with the science.

When Shakespeare asked, "To be, or not to be?," he did not provide the answer. But computer science can! The answer is FF. 

 ( 2B || !2B = FF .. in binary 001001011 OR 110110100=11111111)

Chuck Norris can delete the Recycling Bin.

When Chuck Norris throws exceptions, it’s across the room.

Have you heard about the new Cray super computer? It’s so fast, it executes an infinite loop in 6 seconds.

Question: Is there a way to get e-mails when someone changes something here at the APCSWiki?

Answer: By using the services at http://www.watchthatpage.com/ You can watch any page and send the changes to that page as an e-mail to one or more people. This works very well on the AllRecentChanges page for monitoring a whole wiki. As it is a completely separate service, there is no change required to the monitored wiki, so you could use it to monitor our wiki, http://www.stfrank.com/apcswiki/index.php

  1. Goto http://www.watchthatpage.comand create a user account.
  2. Add a new watched web page. Go to "Pages" and add the wiki's AllRecentChanges page. The url is http://www.stfrank.com/apcswiki/index.php?n=Site.AllRecentChanges
  3. Add the times the e-mails will be sent out, e.g. daily at 6.am or twice-daily etc. This is under the "Profile" tabs
  4. We have a Sandbox, so you may want to exclude changes to the Sandbox pages from being e-mailed out. To do that, add a filter on each paragraph that contain the word 'Sandbox'.
  5. We have dynamically changing content on our page footer (the time) so you may need to add further filters to ignore those changes, or remove them from the RecentChanges page.
  6. Add additional recipients of the e-mails, say if you want it sent to multiple e-mail accounts, or your less talented friends who cant figure out how to do this.

That's it! Multiple edits to the same page will not result in multiple lines in the RecentChanges page, hence won't result in multiple lines in the e-mails. If no changes are made, no changes occur on the RecentChanges page and no e-mail is sent out.
