• iPhone SDK 3/4 App will not run on a iPhone 2.x device even with deployment target set to 2.0!

  - by MarqueIV

  Ok... I know about the difference between the base/active SDKs and the deployment target. I have my base SDK set at 4.0 and the deployment target set at 2.0. I am not using any APIs post 2.x, conditional or otherwise. Since I can't debug on a 2.x device, after building it, I use the iPhone Configuration Utility to install the app on the device, which it does just fine. Problem is, it doesn't run! I just get a blank screen. The main window never comes up! Now before you ask... I had this same problem with the iPhone SDK 3.x. I upgraded to the 4.x hoping it would be solved. It wasn't. Yes the provisioning profile is installed. (Couldn't install the app if it wasn't.) This same compiled app works fine on 3.x devices. Same with 4.x devices. Just not 2.x devices. Again, no I am not using any post-2.x SDKs. To prove this I created a brand-new, window-based app from the 'New Project' dialog and the only changes I made was the background color of the window (to prove the XIB loaded) and I set the deployment target to 2.0 (It's still compiled against the 4.x SDK though.) Again, it runs fine on 3.x or 4.x devices, but just a black, blank screen on 2.x devices. I've tried this on three separate 2.x devices included one freshly restored. I've used three separate dev machines (MacBook Pro with the 3.x SDK, MacBook Pro with the 4.x SDK and a Mac Pro with the 3.x SDK.) Same result every time. I am stumped. The fact that even an unmodified project doesn't run really has me confused. Could it be the XIB file? Did they change the format from 2.x to something newer in the 3.x SDK? If so, how do I set it back to 2.x. (Again, this is just a complete guess.) But I'm really stumped! Mark

• Is VirtualBox really slow compared to the host OS? (for Ruby development)

  - by dan

  I have VirtualBox running Ubuntu as a guest environment on my Macbook Pro running Leopard OS X 10.5. I timed the same batch of Ruby on Rails unit tests on both systems. The difference seems to be quite big. The same suite of Ruby unit tests that take 13.4 seconds in the native OS X, take 82 seconds to run in VirtualBox Ubuntu. Are other people doing the same kind of development noticing the same differences?

• How can I drop a SqlServer Backup Device using SMO in C#?

  - by C-Pound Guru

  I can drop a SqlServer Backup Device using SQL-DMO using the following pseudo-code: SQLDMO.SQLServer2 server = New SQLDMO.SQLServer2(); server.Connect("myserver"); server.BackupDevices.Remove("mybackupdevice"); File.Delete("mybackupdevicephysicallocation"); SMO.Server.BackupDevices does not appear to have a Remove() method, so how can I drop a BackupDevice using SMO?

• How do I determine whether it's a mobile device with PHP?

  - by Thomaschaaf

  I am writing a website with PHP. Since it will need to be accessed by anyone on the network to access the internet I have to create a mobile version. How do I best check if it's a mobile device? I don't want to have a switch statement with 50 devices at the end since I don't only want to support the iPhone. Is there a PHP class I could use?

• Do you use an architectural framework for Flex/AIR development?

  - by Christophe Herreman

  Given that Flex is still a relatively young technology, there are already a bunch of architectural frameworks available for Flex/AIR (and Flash) development, the main ones being Cairngorm and PureMVC. The amount of architectural frameworks is remarkable compared to other technologies. I was wondering how many of you use an architectural framework for Flex development. If so, why, or why not if you don't use any? To share my own experience and point of view: I have used Cairngorm (and ARP for Flash development) on a variety of projects and found that at times, we needed to write extra code just to fit into the framework, which obviously didn't feel right. Although I haven't used PureMVC on many occasions, I have the same gut feeling after looking at the examples applications. Architectural frameworks equal religion in some way. Most followers are convinced that their framework is THE framework and are not open or very skeptical when it comes to using other frameworks. (I also find myself hesitant and skeptical to check out new frameworks, but that is mainly because I would rather wait until the hype is over.) In conclusion, I'm thinking that it is better to have a sound knowledge of patterns and practices that you can apply in your application instead of choosing a framework and sticking to it. There is simply no right or wrong and I don't believe that there will ever be a framework that is considered the holy grail.

• Android: Any way to auto-pair to another device over Bluetooth without prompting for a pin?

  - by D.

  I am looking for a way to connect to Android devices via Bluetooth without user intervention(assuming at least on device is set to "Discoverable"). Since 2.0, it seems the devices prompt for a random pin to be entered when connecting to each other for the first time. I've tried some Bluetooth projects, but none seem to work as the underlying Bluetooth Adapter code always kicks in. Is there any way around this? Thanks.

• How can I tell reliably if my Android App is running on a device with JIT?

  - by Keith Twombley

  Is there a way to test, from within an android app, if the device it's running on is actually using the Froyo JIT? I ask because I know that 2.2 has a JIT, but we've already had a few test builds that seem to lack the JIT. So it's not a case where you can just test for the api version and be assured you've got the JIT.

• What open-source applications do you use for software development?

  - by George Edison

  Figured this question would have a happier life here than on SO. So, what open-source software does everyone use? I'm referring to programs that are used to aid in the development of software. So this may include for example, the Gimp (for application artwork), but not a bittorrent client. Some of mine: Code::Blocks Mingw32 7-Zip InnoSetup

• What is the best way to do development with git? [closed]

  - by marlene

  I have been searching the web for best practices, but don't see anything that is consistent. If you have an excellent development process that includes successful releases of your product as well as hotfixes/patches and maintenance releases and you use git. I would love to hear how you use git to accomplish this. Do you use branches, tags, etc? How do you use them? I am looking for details, please.

• How does an Android/iPhone device implement text-zooming?

  - by rcoyner

  Simple question - how is text-zooming implemented on an Android/iPhone device? Do they pre-compute frequently used bitmaps of a font and replace the text as the scale changes? Or do they extract the contours from the font files and render the text as vector graphics?

• Determining if an Activity exists on the current device?

  - by stormin986

  Is there a way to check and see if an Activity exists on your device? If I have a youtube video link I want to specify it open in the YouTube PlayerActivity. However, I don't want to crash if for some reason they don't have it. Is there a way to check and see if the activity exists? I don't think I can catch the runtime exception since startActivity() doesn't throw it.
