[POTUSCamacho] listens to his @public_timeline rss feed. In part one of his project, he describes creating a bash script in which he uses cURL get his private feed, sed to clean it and eSpeak to output a WAV file. In parts two and three, he goes on to discuss how he created an audio stream (currently down, opens in a new window) of @public_timeline and how he plans on tweeting vocally.
BadPoetry WordPress 2.7 has just been released and features a complete interface overhaul. Hack a Day runs on WordPress MU hosted by WordPress.com, so we got this update last week. We run standard WordPress.org on all of our personal blogs though. We recommend it because it’s free, has a massive userbase, and if you host it yourself, you can do whatever you want with it.
To make the upgrade process as simple as possible (and for the sheer rush of ‘rm -rf’), we use a one line command.
$ curl http://wordpress.org/latest.zip -o "wp.zip" && unzip wp.zip && rm -rf ./wordpress/wp-content/ && cp -r ./wordpress/* ~/www/
curl downloads the latest version from wordpress. unzip unpacks all of the files into a directory called ‘wordpress’. rm -rf removes everything in the ‘wp-content’ directory. Otherwise, you will overwrite your images, themes, and plugins. cp -r copies everything to your http document root, overwriting the previous install.
Naturally, you should back up your current install and database beforehand. We tend to use the one-liner with reckless abandon. If you’re wondering about the terseness, it was designed to fit inside the 140 character limit of Twitter.

It seems that people keep coming up with ingenious things to with Twitter. Reminding you to water your plants is relatively inventive, but for shear practicality, [Shantanu Goel] created a security camera using a webcam, a few freeware apps, and a Twitter account.
To make this work, install Motion on a system running Linux. As its name suggests, Motion is a free motion-detecting application that monitors movement in a webcam’s field of view. Once installed, it should be configured to take a snapshot of the event whenever something moves; with the locate option turned on, it draws a square frame around the area where motion occurred. The program includes http server functionality, so the photos can be viewed from a remote location. When all of that is properly configured, motion can be set to trigger cURL, Wget, or [Goel]’s Perl script to post a message to Twitter about the event. From there the Twitter account can be configured to send text messages to a phone, creating a virtually instant notification of motion sensed by the webcam.
