In yet another sign of a more open Apple, the company has debuted a new blog dedicated to its new Swift programming language. Promising to provide a “behind-the-scenes look into the design of the Swift language” from Swift engineers, the blog currently has only one entry, but it’s a good one: an announcement that the Xcode 6 beta is now available for free download (formerly, downloads of Xcode betas required a paid Apple developer account). As the blog has no reader comment capability, we don’t foresee the blog becoming a forum in which developers can offer their own suggestions for improvements and enhancements to the language, so it will be interesting to see just what Apple does with the blog in the coming weeks and months.follow link
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
