I searched all over the web about this problem but was unable to find the root cause of the problem. I then decided to try out re-compiling in VS Express and was presented with lots of compile errors. That’s when I realized that mono’s compiler (specifically vbnc) is not as good as it’s supposed to be (yet). And that you should still try to compile with VS every now and then just to make sure everything’s working.

Lesson of the story: If you get this error, try compiling with VS to see if there are other problems.

I searched the web and most of the blogs/tutorials I found mentioned that I needed to create a provisioning profile in my iPhone developer account which is configured for push notifications.

I was pretty confident that my account was setup properly because I was already able to send push notifications before using an app id that I created so I assumed the problem was with my development setup.

Below are the steps I followed to make push notifications working again:

1. Check whether the profile you’re using for the application is the one configured with push

Often times developers will have multiple provisioning profiles to test and develop on devices. In my case, I had a generic/wildcard profile (BLAHBLAHXX.*) for deploying on the device and another profile for an actual app configured for Push notifications (BLAHBLAHXX.com.companyname.appname).

I was using the generic profile when I checked so I had to switch that back to the profile configured for push. To edit your setting choose Project > Edit Project Settings > Code Signing and then choose the appropriate profile.

2. In case step 1 did not fix your problem (like in my situation), delete all the apps in your device which use the provisioning profile for push notification and perform a soft reset.

3. In Xcode, try to clean all targets. Reboot your machine (probably not necessary but it does wonders most of the time). Then re-build and deploy.

I was back in business with APNS after following those three steps.

HTH.

Fatal error: Call to undefined function wp_dashboard_setup() in /home/username/public_html/wp-admin/index.php on line 15

I didn’t make any changes or upgrades to the site and the weird part is that all of a sudden, two of our WordPress installations were displaying this error.

UPDATE: March 24, 10:12 PM GMT+8 It looks like the problem is related to A2 Hosting changing the default PHP version (see Neil’s post in the comments section).

I did some Googling and found a workaround.

The solution is to change this line in wp-admin/index.php:

require_once(ABSPATH . 'wp-admin/includes/dashboard.php');

to this line:

require_once('./includes/dashboard.php');

I’m still trying to investigate the cause of the problem but in the meantime, hope this quick fix solves your problem.

Thanks to Florent for sharing his solution. And thanks also to Neil for providing the reason for the error and a better approach to handling the problem for those who are with A2 Hosting.

But don’t fuss, because it’s not that hard to configure SVN support (using Subversive) with a few simple steps. This document aims to guide you with the install process.

The first time you try to run Eclipse Galileo and click any of the update sites, you’ll probably receive the “Unable to read repository at …” error like what is shown below:

To fix this problem, simply select “Galileo” (or any other update site you wish to use) from the “Available Software Sites” link (Help>Install New Software) and click the “Test Connection” option on the right.

Click “OK” when done and select “Galileo” from the “Available Software” dropdown.

From the Galileo Update site, choose “Collaboration > Subversive SVN Team Provider”.

Click Finish/OK when done. Due to licensing restrictions, the connectors need to be installed using another update site.

To do this, simply “Add” the “Subversive SVN Connectors” Update Site: http://community.polarion.com/projects/subversive/download/eclipse/2.0/galileo-site/

Select the Subversion Connectors you need (select all if you’re not sure which ones) and Install.

After the installation process, you will be  asked for restart of a Eclipse for the changes to take effect.

To see the available options for SVN, open the “SVN Repository Exploring” perspective.

Hope this helps. Comments and feedback are much appreciated.

Thanks.

My problem: there was blank space (about 20 pixels) showing between the status bar and the Nav Bar. I tried looking in the Nibs about setting this value but without luck.

What’s even weirder is the fact that this problem does not occur when running against the OS 3.0 simulator.

Fortunately, after days of searching, I found the workaround for OS 2.2.1 and below.

    CGRect frame = navController.view.frame;
    frame.origin.y = 0.0;
    navController.view.frame = frame;

I have been used to clicking that little “Show Desktop” icon on the bottom left of the screen in Windows and was looking for an equivalent on my Mac.

Fortunately, there is! But it’s not an icon that you would click but some keyboard shortcuts you need to type. For me pressing fn F10 did the trick.

We encountered a problem when we needed to convert one of our routines for writing out a binary file. We were using Java’s DataOutputStream.writeUTF(String) method and had a hard time trying to write binary data in PHP.

After much research on the web, we found a method in PHP called pack(). Below is our PHP implementation of Java’s DOS.writeUTF(String).

	public static function writeUTF($string) {
		$utfString = utf8_encode($string);
		$length = strlen($utfString);
		print(pack("n", $length));
		print($utfString);
		flush();
	}

We don’t claim this to be the exact equivalent of the method, but it gets the job done and the receiving end of the file was able to parse the binary file properly with the new PHP implementation with no modifications to the client code.

Please checkout the pack() documentation for more details.

Then CTRL-B and CTRL-F should do the trick.

Here’s what you need to have:

* Internet access (to download Windows 7 RC and get updates)
* A PC with these system requirements:
o 1 GHz or faster 32-bit (x86) or 64-bit (x64) processor
o 1 GB RAM (32-bit) / 2 GB RAM (64-bit)
o 16 GB available disk space (32-bit) / 20 GB (64-bit)
o DirectX 9 graphics processor with WDDM 1.0 or higher driver

Ubuntu 9 also is now available for download and was reported to be “as slick as Windows 7 and Mac OS X”.

I wonder when we can see a preview of Snow Leopard…
