It started out as such a great idea: “a twitter tag where people could ask questions without being judged.” Unfortunately we live in a society where, as Carl Honore quite brilliantly said in his TED speech, “instant gratification takes too long.” Combine this with the fact that most people are plain lazy and the great idea that was #durftevragen (the dutch variation of #daretoask) soon became a source of great annoyance.
Last week I was making an implementation of the command pattern, and while doing so I encountered some strange behavior in my flex code that I couldn’t explain… After about a day of puzzling I finally figured it out, it’s all in the arguments!
One of the challenges of developing for mobile devices is making your app run fast, even though it only has very limited capabilities. This is the problem we’ll be adressing in this post, or to be more exact, we’ll be adressing how to get your images fast and efficient on a mobile device. Now obviously you can’t get your image faster than the device’s connection allows, but you can make sure you’re not waiting for downloads that you don’t have to wait for. This is where the image cache comes in. If you have an image, why not just reuse it when requesting it for the second time? Of course there are situations where this sort of behaviour is not wanted (for example, when the image on the server has changed), but mostly it will save you time, bandwidth and battery life.
As noted in my previous post (Adobe Air Application Version) Adobe Air has a nifty update framework. Using this framework you can add a cool automatic update check and install feature in your Air app.
The framework gives you the possibility to use the default UI or a custom UI, and we will (of course) take the long and hard way to create our own UI. With long and hard I mean that we have to do the Alert creation and result handling by ourselves, which sounds a lot worse than it actually is
Okey, so here’s the problem: I’ve got this Adobe Air application which I regularly update using the new built-in Air updater (see my post about the Adobe Air update framework) and I want to include the version number in the title of the app.
Welcome to my brand new site! Soon you will find information about my daily work as a computer scientist, as well as random posts about things that interest me.
Hope to see you soon and don’t be afraid to comment!
