# Keep in mind that when asking for a `return` after another, only the first one will be output.
# This example is meant as a simple starting point, to show how to get the information in the simplest available way.

# Google Chrome
tell application "Google Chrome" to return URL of active tab of front window
tell application "Google Chrome" to return title of active tab of front window
# Google Chrome Canary
tell application "Google Chrome Canary" to return URL of active tab of front window
tell application "Google Chrome Canary" to return title of active tab of front window

libdispatch efficiency tips

The libdispatch is one of the most misused API due to the way it was presented to us when it was introduced and for many years after that, and due to the confusing documentation and API. This page is a compilation of important things to know if you're going to use this library. Many references are available at the end of this document pointing to comments from Apple's very own libdispatch maintainer (Pierre Habouzit).

My take-aways are:

• You should create very few, long-lived, well-defined queues. These queues should be seen as execution contexts in your program (gui, background work, ...) that benefit from executing in parallel. An important thing to note is that if these queues are all active at once, you will get as many threads running. In most apps, you probably do not need to create more than 3 or 4 queues.

• Go serial first, and as you find performance bottle necks, measure why, and if concurrency helps, apply with care, always validating under system pressure. Reuse
