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

Basic macaron shell recipe

• This will make approximately 100 shells, or about 4 dozen cookies
• When practicing, I generally half this recipe to only make 1 sheet of cookies
• When making macarons, you will generally flavor the filling but not the shells
• You want to make the macarons the day before the event. You will store them in the refrigerator over night, and then take them out a few hours before to come to room temperature. This is because macarons are best when "ripened", or allowed to sit for at least one night and have the filling seep into the shells a bit. Otherwise, straight out of the oven, they can be too crunchy or hard
• Macarons shells freeze well! Filled macarons can also freeze well depending on the filling. Buttercream fillings freeze great. Put the cookies into an airtight container before freezing
• Everyones baking temperature and baking time vary depending on their oven - you might have to experiment a bit!
• _I always separate egg whites myself by cracking the egg, p
