With iOS 9, Apple introduces Unique Constraints for Core Data. This new feature was briefly demonstrated at WWDC in June (Session 220). When I tried to implement it, I came across a few pitfalls and unexpected behavior, so I thought this might be worth a blog post.
Unique Constraints are a way to declare a custom attribute to be unique across all instances of an entity. Its intended use case is the import of external data that should be merged with existing objects in the database.

This is just a quick note that I’ve uploaded some minor changes to the SoundCloud-AS3-API on github. I finally added a method to retrieve a signed URLRequest for any API resource. This comes in handy when you want to access the stream of a private track. Continue reading SoundCloud-AS3-API: Small Update and new URL
If you want some more sample code for the SoundCloud-AS3-API, look no further: I just pushed the Scup repository to github: http://github.com/dorianroy/Scup. Continue reading Scup Source Code Released
I’ve just released a minor update for Scup. If you have already installed Scup, you should get the update automatically the next time you launch it. If not, get it here.
The new version 1.1 adds the new set type “Sample Collection”, enables bulk editing of the track type parameter and fixes a few issues (thanks for your bug reports!). Continue reading Scup 1.1 released – now runs on Linux as well
First I was very excited when I saw the new Facebook Like Button. But when I checked the code to see how it works, I noticed that this button actually allows Facebook to track all the Facebook users on your site, no matter if they click it or not (see my previous post on how this works).
As a publisher, you might not want to annoy the visitors of your site with that. So I hacked together an alternative like button, that only connects to Facebook if you click it. Continue reading How To Make A Friendly Facebook Like Button
Facebook has introduced a new Like Button together with some other “social plugins” at their f8 conference last week. Everybody can put it on their website so that visitors can “like” a page and add it to their Facebook profile without leaving the site.
This button actually allows Facebook to track all visitors of the external site, no matter if they click it or not (as long as they are Facebook users – but who isn’t?). Continue reading How Facebook’s Like Button Works
That’s right, Scup is now out of beta! You can grab the 1.0-release from the newly designed website dorianroy.com/scup. If you have already installed Scup, you should get the update automatically the next time you launch it.
And if you haven’t heard of Scup before, here’s what it’s all about. Continue reading SoundCloud Uploader Scup 1.0 released
I just wrote a new tutorial for the SoundCloud AS3 API, “How to Go Through OAuth Authentication in a Single Browser Window”. This tutorial explains how to set up a web-based Flash application in a way that the user stays in the same browser window during the OAuth authentication and does not need to copy /paste the verification code manually. Continue reading New Tutorial and Updates for the SoundCloud AS3 API
The recent discussion about whether the web needs Flash or not was overdue. My opinion is this: Yes, we need an alternative to Flash Player, and HTML5 could soon replace it in most cases. But most of all we need a good IDE to develop content for modern browsers.
Flash has two critical shortcomings that make it hard to use for many projects, not only on mobile devices: Continue reading We don’t need Flash on the iPad, we need better tools to build HTML5 sites
Today I’ve released a little AIR tool for all SoundCloud heavy-users. It’s called Scup, which is short for SoundCloud Uploader – and it does just that. You can upload tracks from your desktop by simply dragging them on the program window and then create a set (i.e. a playlist) consisting of these tracks. Grab it here! I hope you’ll find it useful.
