I recently became aware (thanks, @ppadley!) of a pretty awesome little AppleScript that pulls tweets out of your Keynote presentation's Presenters Notes and posts them to your Twitter timeline. Unfortunately, though, the simple way it used to work was broken when Twitter switched to using oAuth instead of 'basic' (username and password) authentication for using its API.
Luckily, the project, Keynote Tweet, was updated and posted to GitHub, and works in tandem with twurl, a simple Ruby-based command-line Twitter client. Here's how you can get these things working for your own presentations:
Set up a Twitter App for API Access
Before you can post to Twitter from your computer (or anywhere besides an existing Twitter app/client, really), you need to create a Twitter App so Twitter will let you interact with the Twitter API.
Go to https://dev.twitter.com/apps/new, and fill out the form. Edit the app's settings and set your app to 'Read + Write' access, and then save the settings. Copy your consumer key and consumer secret and save these for later.
Install and configure twurl
On Mac OS X, since you already have ruby installed, you just need to install the twurl gem (which will also install the oauth dependency). In Terminal, enter the following command (without the $):
$ sudo gem i twurl --source http://rubygems.orgWait for the install to finish, and when it's all done (and you're back to the terminal prompt), you need to authorize twurl with your consumer-key and consumer-secret (from the earlier step). Enter the following command in the terminal, substituting the all-caps keywords with your key and secret:
$ twurl authorize --consumer-key KEY --consumer-secret SECRETAfter you press enter, twurl will return a URL and some instructions. Copy just the URL and paste it in your browser window. Then click on 'Authorize App', copy the key code from Twitter, and paste it back in the Terminal, then press enter again to save the key. Twurl should report that everything is good to go!
Add Tweets to your Presentation
In your Keynote presentation, add tweets by adding text inside [twitter][/twitter] in individual slides' presenters notes. Then launch the Keynote Tweet app (if you get a 'this app is unsigned' notice, right or control-click the app and select Open to open it), and enter in a hashtag if you'd like one to be added to all your tweets. Click okay, and then start your presentation (while the Keynote Tweet app is running). Your tweets should be posted to Twitter when you go to slides with the tweets in the presenters notes.

Dear Jeff:
I have seen your I-phone video and was wondering if you can help me out.
I am a Constable Elect in Texas; meaning I am an elected official working in the capacity of a law enforcement officer. I have been advised to use a I-Pad with law enforcement software. I am looking into using a wireless microphone while making traffic stops while recording the stop on the I-pad.
I need two things if you are willing to help me out. 1. I need to find a good audio wireless device to use up to 150 feet away from the I-pad while recording the video of the traffic stop. 2. I need a split screen of video recording me at the vehicle with audio and at the same time video and audio of the subject in the vehicle in the back seat.
Is there anyway to record on the I-pad using the front camera and the back camera simultaneously with wireless audio.
I am sure you are extremely busy but would appreciate any advice you can supply.
Thank you,
Chris Johnson
Ps.
I would be more than willing to talk to you on the phone.
Thanks for the comment and question! I would recommend the Audio Technica Pro 88W for wireless microphone (should work in almost every situation, might have a little static if you go all the way to 150+ ft., but would still pick up sound), but as far as I know, there's no way to use both the front and rear cameras in one video recording app (yet), since the iOS AVFoundation components don't allow concurrent access to both cameras; you can only switch between the two.
