Convert sequence of JPEG images to MP4 video

ffmpeg -r 24 -pattern_type glob -i '*.JPG' -i DSC_%04d.JPG -s hd1080 -vcodec libx264 timelapse.mp4

• -r 24 - output frame rate
• -pattern_type glob -i '*.JPG' - all JPG files in the current directory
• -i DSC_%04d.JPG - e.g. DSC_0397.JPG
• -s hd1080 - 1920x1080 resolution

Slower, better quality

Virtual DOM and diffing algorithm

There was a [great article][1] about how react implements it's virtual DOM. There are some really interesting ideas in there but they are deeply buried in the implementation of the React framework.

However, it's possible to implement just the virtual DOM and diff algorithm on it's own as a set of independent modules.

Grunt and Cordova 3

The advantages of using Grunt with Cordova:

1. It simplifies working with the cordova cli.
2. It provides a mechanism to copy platform customization to the platforms directory without having to commit the generated plugins and platforms directories to version control.
3. It provides a way to watch resources and automatically run cordova commands.

tl;dr

1. Don't run as root.
2. For sessions, set httpOnly (and secure to true if running over SSL) when setting cookies.
3. Use the Helmet for secure headers: https://github.com/evilpacket/helmet
4. Enable csrf for preventing Cross-Site Request Forgery: http://expressjs.com/api.html#csrf
5. Don't use the deprecated bodyParser() and only use multipart explicitly. To avoid multiparts vulnerability to 'temp file' bloat, use the defer property and pipe() the multipart upload stream to the intended destination.

AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

1. Raw Attribute Strings

   <div my-directive="some string" another-param="another string"></div>
