/**
 * Wraps C++ classes (ptrs and refs) so that they can be passed around in
 * Objective-C++ programs without generating a lot of useless Objective-C
 * runtime metadata.
 * Use objc_metadata_hider_ptr for ptrs and objc_metadata_hider_ref for refs.
 * Example use:
 * ```
 *   class Foo {
 *     public:
 *       ....

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

How to Change Open Files Limit on OS X and macOS

This text is the section about OS X Yosemite (which also works for macOS Sierra) from https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/#mac-os-x

The last time i visited this link it was dead (403), so I cloned it here from the latest snapshot in Archive.org's Wayback Machine https://web.archive.org/web/20170523131633/https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/

Mac OS X

To check the current limits on your Mac OS X system, run:

Sony Bravia HTTP API

The sony bravia has a HTTP API interacted with using a Pre-Shared key. There's a more complex auth flow but I've not described it here.

There wasn't any documentation, so I've written some. If you're a TV integrator don't read this, you'll laugh. I'm probably just getting confused by UPnP.

Disclaimer: I've only tested this on my TV, which is a KDL-50W829B. Your TV might not have all of the services; see Available services section for how to discover what your TV supports.
