I managed to mis-type a colleague's email address when sending him an email and Mac Mail them memorised it and tried to use it whenever I typed that user's name. Here is how to remove entries:

Well, a pretty good flight to the Plone Planning Summit. A long, but so far good journey. The taxi picked me up at 4:30am, and at 10pm I'm finally in San Francisco waiting for the train into town. Every city has its own nuances with their public transport system, but San Francisco has a new one on me: With the BART train you buy a ticket from a machine... sounds simple enough, but when you put in a note, eg. $20 it defaults to a $20 ticket, and you have to hit buttons to *remove* value from the ticket. I needed a $5.30 ticket, so put a $20 note in, and hit 'remove $1' several times, until it got to $15 then stopped and wouldn't go an further. Confused I ejected my $20 bill and looked around and spotted a change machine.

Sticking the 20 into that, I got four $5 bills back. Back to the ticket machine, I put two $5 bills in, and then had to hit 'remove $1' four times, then 'remove 5c' button fourteen times until I got to my fare. Wouldn't a numeric keypad be easier?!

Speaking of which, getting cash out the ATM was also an odd one, as it asks you to key in the amount you want to withdrawal, but with two decimal places, ie for $100 you hit one then four zeros. Yet above the entry box it says it only dispenses $20 bills. So why the two decimal places?!

You do have to wonder sometimes if the moon landing conspiracy theorists were on to something!

To give me the ability to distract colleagues all as often as possible, whilst taking as little time out of my own day, I have an 'email this page' bookmarklet set up for firefox.

Basically its a tiny piece of javascript that pops up a pre-filled email to 'staff', with the title of the page as the subject, and the url as the message body.

To create a bookmarklet, first bookmark any page and stick it in your Bookmarks Toolbar, then right click it -> properties.

Change the name to whatever you like, and the location to this:

javascript:window.location = 'mailto:somebody@somewhere.com?Subject=' + document.title + '&body=' + document.location

Ta da! Instantly share useful links / hilarious tat with the whole office.

(p.s. you can do this in Safari too - not sure about IE)

If you don't want to be nagged by the new Emacs 22 splash screen anymore then simply stick this line in your .emacs file:

(setq inhibit-startup-message t)

Voila.. Richard Stallman will now leave you alone to edit your files in peace without telling you how great he is everytime you start it :)
