Hidden classes in JavaScript and Inline Caching

Knowing how internals work is always a good. Pretty much for everything. Cars, trains, computers, you name it. It gives you an insight on what happens under the hood. You also act/react differently based on this knowledge.

As you might have guessed, it’s also true for web development. Knowledge of CSS transitions allows you to achieve better performance and not to use JavaScript in most cases. Knowledge of V8 internals allows you to write more performant JavaScript code. So let’s talk about V8 a little.

A little about V8

V8 is a JavaScript engine built by Google. Firefox built SpiderMonkey, Opera built Carakan and Microsoft built Chakra. One very important difference between V8 and other JavaScript engines is that V8 doesn’t generate any intermediate code. It compiles JavaScr

Close Android File Transfer
Open Activity Monitor and kill “Android File Transfer Agent”
Go to where you installed “Android File Transfer.app” (I have it under /Applications)
Ctrl+click –> “Show package contents”
Go to Contents/Resources
Rename “Android File Transfer Agent” to e.g. “Android File Transfer Agent_DISABLED”
Then go to “/Users/username/Library/Application Support/Google/Android File Transfer” and again rename the Agent app.

DIR=$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )

Is a useful one-liner which will give you the full directory name of the script no matter where it is being called from

These will work as long as the last component of the path used to find the script is not a symlink (directory links are OK). If you want to also resolve any links to the script itself, you need a multi-line solution:

SOURCE="${BASH_SOURCE[0]}"
while [ -h "$SOURCE" ]; do # resolve $SOURCE until the file is no longer a symlink
