How to update regular Eclipse Kepler to Java EE [WTP, Webtools]

If you're like me who downloaded the Standard Edition of Eclipse in the hopes of saving space and maybe performance (Because I was supposed to just use it as a CVS client for Mac OS), then you'll also realize later that you should've downloaded the Java EE version instead because Eclipse's Web Tools Platform is very useful.

I tried the Eclipse Market Place and the Install New Version menu (using existing update sites) to no avail.

If you tried searching the web how to update Eclipse to J2EE version without downloading the entire Eclipse again, then it is most likely that you've probably ended up in an outdated documentation pointing to an old Webtools repository.

To cut to the chase, to add Webtools Platform (WTP) to Eclipse Kepler, go to Help > Install New Software

Add http://download.eclipse.org/webtools/repository/kepler/ to Location and Name it whatever you like e.g. Webtools Kepler. Check the Web Tools Platform and update your Eclipse. After installation you should now have the Java EE perspective and the various editors for Javascript, HTML, CSS, and other web components.

For other version of Eclipse, it's will highly likely follow the pattern

[Solved] Smooth Div Scrolling in iPad Browser (or iPhone / iOS Devices)

If you have a scrollable div using overflow: auto or overflow: scroll, you will notice that the scroll is slow or choppy. To make the inline scroll smooth, just add the following in your css class:

-webkit-overflow-scrolling: touch;

E.g.

#SCROLLABLE_DIV {
  height: 300px;
  overflow: auto;
  -webkit-overflow-scrolling: touch;
}

[Solved, Mac OS X] Disable web security in Chrome

Execute this in terminal:

open /Applications/Google\ Chrome.app/ --args --disable-web-security

I use the above settings when testing Backbone JS + Require JS + Underscore JS + Text Plugin to read files from file system. Google Chrome won't allow it unless the above parameter is set. This is also related to disabling Chrome's Same Origin Policy.
