How to Properly Test if jQuery is Loaded
I saw many people claiming you can test for the existence of jQuery like this:
1 2 3 4 5 | if (jQuery) { // jQuery exists, put code here } else { // jQuery not loaded, put code here } |
This is incorrect. It will work fine if jQuery is loaded, but if it's not loaded, javascript will throw an error and the code to execute if jQuery is not loaded will probably not be processed. The modification to fix this is simple:
1 2 3 4 5 | if (window.jQuery) { // jQuery exists, put code here } else { // jQuery not loaded, put code here } |

How to Hide Android WebView Highlight Border (or change it’s color)
Here's one that had me at a loss for a long time that I just figured out. You can easily remove the highlight border (the border that comes up when an element is focused) or change it's color in a WebView with CSS! The WebKit-specific property "-webkit-tap-highlight-color" is what you're looking for.
The following line will disable it on a page completely:
1 2 3 | * { -webkit-tap-highlight-color: rgba(0, 0, 0, 0); } |
rgba() is just like rgb(), but it takes a 4th parameter for opacity. It's my belief that this would probably work for iPhone WebView's as well, since both Chrome and Safari are based off of WebKit.

How to fix linux not sending mail problem: Sendmail stat=Deferred: Connection refused by [127.0.0.1]
I recently experienced a problem where my server was not sending mail from the PHP mail() function or the command line "mail" function. After looking through /var/log/maillog, I was able to see that the local 127.0.0.1 mail server was refusing the connection. Some Google searching landed me at the following thread, where the third post did the trick:
