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

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

This is what Craft does:

function loadFramework(pluginRoot) {
  if (NSClassFromString('PanelsManager') == null) {
    var mocha = [Mocha sharedRuntime];
    return [mocha loadFrameworkWithName:'Panels' inDirectory:pluginRoot];
  } else {
    return true;
 }

//  UIView+Orientation.h

#import <UIKit/UIKit.h>

// These macros should only be used if you MUST know the interface orientation for the device itself, for example when displaying a new UIWindow.
// This should be very rare; generally you should only look at the immediate parent view's size (or "view orientation" using the category below).
#define StatusBarOrientationIsPortrait      UIInterfaceOrientationIsPortrait([[UIApplication sharedApplication] statusBarOrientation])
#define StatusBarOrientationIsLandscape     UIInterfaceOrientationIsLandscape([[UIApplication sharedApplication] statusBarOrientation])
