A few days a week I work a half day at Starbucks (or similar) and don’t purchase the internet. I go totally offline to focus on whatever mentally intensive tasks I’m currently working on. For the most part this works out well, but one thing I miss when programming is easy access to PHP documentation. I’m addictated to using the quick search on php.net (www.php.net/fopen, etc). I found this little app a while back which makes the docs available offline, including the comments. If you’re in need of such an app I highly recommend it. What’s best is that it’s super simple and doesn’t go too far. It’s OS X only so Win users are out of luck.
