Spring cleaning

Ok folks, that’s it… A few days ago, I decided to close all my software development activities on my main site, eosgarden.com. It was a tough decision to make, as it implies the discontinuation of all previously published software. But I really needed to stop focusing on the past, and on software I originally developed [...]

Apple vs the World (again)

iOS 6 is now close to release. Today, Apple made iOS 6 beta 4 available to registered developers. From a developer’s perspective, there’s quite a lot of changes. New APIs, new frameworks, changes in the default UI behavior, better iCloud support (let’s say so), etc. As usual you may say. It’s not [...]

Apple kills the FileSystem App

A few month ago, I decided to update my `FileSystem` iPhone app, available on the AppStore since a few years now. The purpose of the App was to let you access (read-only) the complete iOS filesystem, displaying every directory, file, file contents, etc. Just like a Finder on OS X. When I started iOS development back then, [...]

When working on a software project, you may sometimes have to mix programming languages. It may be because you need to use some specific libraries, because of code portability needs, whatever. When coding a Mac OS X (or iOS) application, you are usually going to use Objective-C as main language. It’s not mandatory, [...]

That example is typically [...]
