There’s no substitute for hands-on experience, but for most students, real world tools can be cost prohibitive. That’s why Github created the GitHub Student Developer Pack with some of our partners and friends: to give students free access to the best developer tools in one place so they can learn by doing.
More than 100,000 students have already taken advantage of free access to GitHub, collectively pushing code more than 50,000 times per day. With the GitHub Student Developer Pack, students now have free access to an entire suite of useful developer tools.

Adding a Login with Facebook option to your web app is a pain! The process requires multiple requests to the Facebook API, and usually results in a messy callback soup that you get stuck managing.
jQuery.fblogin simplifies logging in with Facebook by jQuery. You will need a valid Facebook App Id and the Facebook JS SDK loaded to use the plugin. If you have used the jQuery.ajax() method before then using fblogin should seem familiar. Simply call $.fblogin(options) where options is an object with the desired settings.
Requirements: jQuery Framework

Websites don’t have a single layout any more. The space you have for an image may be portrait on a laptop, landscape on a tablet, and square on a mobile – particularly if you’re using a full-screen image. If you have to use the same image file in all these contexts, your subject might be clipped or completely missing, or just really awkward looking.
FocusPoint jQuery Plugin makes sure your image looks great in any container, by ensuring the ‘spare’ parts of your image (negative space) are cropped out before the important parts. It’s made for ‘responsive cropping’. Dynamically crop images to fill available space without cutting out the image’s subject.
