SINGLETON_GCD(MyClass);

Conclusion

File system cache is, as expected, faster. Core Data falls shortly behind when storing (marginally slower) but load times are way higher when performing single random accesses.

For such a simple case Core Data functionality really doesn't pay up, so stick to the file system version.

Riaknostic, which is invoked via the above command, is a small suite of diagnostic checks that can be run against your Riak node to discover common problems and recommend how to resolve them. These checks are derived from the experience of the Basho Client Services Team as well as numerous public discussions on the mailing list, IRC room, and other online media.

libCollections is an Objective-C library that brings methods from Smalltalk's collection protocol and Ruby's Enumerable mixin to Objective-C projects. libCollections adds these methods as categories to the Foundation framework's collections classes. (Not all of Ruby's Enumerable methods are implemented, but some of them aren't really relevant or useful and probably won't be.)

Enumerable is one of those things that is hard to live without once you experience it. Great additions to Foundation.

VendorKit makes the process of using and managing libraries in iOS easy. VendorKit is modeled after Bundler. VendorKit streamlines the installation and update process for dependent libraries. It also tracks versions and manages dependencies between libraries.

appledoc is command line tool that helps Objective-C developers generate Apple-like source code documentation from specially formatted source code comments. It’s designed to take as readable source code comments as possible for the input and use comments as well as surrounding source code to generate visually appealing documentation in the form of HTML as well as fully indexed and browsable Xcode documentation set. Although there are several tools that can create HTML documentation for Objective-C, all of those know to me fall short in meeting the minimum of goals described in appledoc’s readme file. Check example documentation to see what you can get and online documentation to see how to get there!

Resty, an Objective-C HTTP framework

Resty is a simple to use HTTP library for iOS and Mac apps, aimed at consuming RESTful web services and APIs.

It uses modern Objective-C language features like blocks to simple asynchronous requests without having to worry about threads, operation queues or repetitive delegation. It is inspired heavily by RestClient, a Ruby HTTP library.

For more information and documentation, check out the project website.

The truth is, filesort is badly named. Anytime a sort can’t be performed from an index, it’s a filesort. It has nothing to do with files. Filesort should be called “sort.” It is quicksort at heart.
