Snow Leopard has a few new under-the-hood changes that are designed to make the life of a programmer that much easier in the heterogeneous, multi-core society that we now live in. To begin with there is OpenCL. OpenCL is a technology for computing with heterogenous hardware such as GPUs and CPUs. It is being covered on MacResearch in David Gohara’s excellent series of screencasts. The other big technology is Grand Central Dispatch (GCD), and that’s what I want to look at in this tutorial. Grand Central is a new approach to parallelism. It does away with the old threaded models, and replaces it with a packet-based approach. In this tutorial, we’ll take a look
Eschatology Ask me how it ends… Skip to content Home About { 2009 08 06 } Using “en” instead of “English” for your Xcode project’s development region Various pieces of Mac OS X and iPhone documentation have said for quite a while that the “preferred” method is now to use ISO-639-1 (two-letter) or ISO-639-2 (three-letter) language codes codes for localization purposes. Out of the box, Xcode’s project templates still use “English” rather than “en” as their default localization. How can you use the ISO-639 language codes everywhere in your project, rather than in just your non-English localizations? It’s pretty straightforward, but it does require hand-editing of your Xcode project file. This means that before doing anything else, you must quit Xcode and Interface Builder. The first step is to rename your existing localizable resource directories on disk from English.lproj to en.lproj. You can do it at the Terminal or in the Finder. If you’re using an SCM system such as Subversion, u
