			<content:encoded><![CDATA[<p>Yesterday I started playing around with Google App Engine and Java. Today, when I tried upgrading the JDK/VM that Google App Engine is using from Eclipse Galileo to Java 6 in Mac OS X, I got the error below:</p>
<blockquote><p>com.google.appengine.tools.development.agent.impl.BlackList initBlackList<br />
SEVERE: Unable to read a jre library while constructing the blacklist. Security restrictions may not be entirely emulated. /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/lib/plugin.jar<br />

			<content:encoded><![CDATA[<p>With Subversive being an official Eclipse project (2007) and the recent Eclipse 3.5 Galileo release (2009), you may be wondering why Eclipse still does not have SVN support built-in.</p>
<p>But don&#8217;t fuss, because it&#8217;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.</p>
<p>The first time you try to run Eclipse Galileo and click any of the update sites, you&#8217;ll probably receive the &#8220;Unable to read repository at &#8230;&#8221; error like what is shown below:</p>
<p><img class="aligncenter size-full wp-image-487" title="Update Error" src="http://unlikelyteacher.com/wp-content/uploads/2009/10/UpdateError-resized.png" alt="Update Error" width="500" height="445" /></p>
<p>To fix this problem, simply select &#8220;Galileo&#8221; (or any other update site you wish to use) from the &#8220;Available Software Sites&#8221; link (Help&gt;Install New Software) and click the &#8220;Test Connection&#8221; option on the right.</p>
<p><img class="aligncenter size-full wp-image-488" title="Test Connection" src="http://unlikelyteacher.com/wp-content/uploads/2009/10/TestConnection-resized.png" alt="Test Connection" width="550" height="388" /></p>
<p>Click &#8220;OK&#8221; when done and select &#8220;Galileo&#8221; from the &#8220;Available Software&#8221; dropdown.</p>
<p><img class="aligncenter size-full wp-image-490" title="Available Software" src="http://unlikelyteacher.com/wp-content/uploads/2009/10/AvailableSoftware-resized.png" alt="Available Software" width="510" height="454" /></p>
<p>From the Galileo Update site, choose &#8220;Collaboration &gt; Subversive SVN Team Provider&#8221;.</p>
<p><img class="aligncenter size-full wp-image-492" title="Collaboration Subversive" src="http://unlikelyteacher.com/wp-content/uploads/2009/10/CollaborationSubversive-resized.png" alt="Collaboration Subversive" width="600" height="272" /></p>
<p>Click Finish/OK when done. Due to licensing restrictions, the connectors need to be installed using another update site.</p>
<p>To do this, simply &#8220;Add&#8221; the &#8220;Subversive SVN Connectors&#8221; Update Site: http://community.polarion.com/projects/subversive/download/eclipse/2.0/galileo-site/</p>
<p><img class="aligncenter size-full wp-image-493" title="Add Subversive Connectors Update Site" src="http://unlikelyteacher.com/wp-content/uploads/2009/10/AddSubversiveConnectorsUpdateSite.png" alt="Add Subversive Connectors Update Site" width="408" height="169" /></p>
<p>Select the Subversion Connectors you need (select all if you&#8217;re not sure which ones) and Install.</p>
<p><img class="aligncenter size-full wp-image-496" title="Select Subversive Connectors" src="http://unlikelyteacher.com/wp-content/uploads/2009/10/SelectSubversiveConnectors-resized.png" alt="Select Subversive Connectors" width="550" height="550" /></p>
<p>After the installation process, you will be  asked for restart of a Eclipse for the changes to take effect.</p>
<p>To see the available options for SVN, open the &#8220;SVN Repository Exploring&#8221; perspective.</p>
<p><img class="aligncenter size-full wp-image-500" title="SVN Repository Exploring Perspective" src="http://unlikelyteacher.com/wp-content/uploads/2009/10/SVNPerspective.png" alt="SVN Repository Exploring Perspective" width="427" height="219" /></p>
<p>Hope this helps. Comments and feedback are much appreciated.</p>
<p>Thanks.</p>

			<content:encoded><![CDATA[<p>I currently have an iPhone application which has 4 tabs, when I click any of those tabs, the application should show a new view with a Nav Bar which then contains a table view.</p>
<p>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.</p>
<p>What&#8217;s even weirder is the fact that this problem does not occur when running against the OS 3.0 simulator.</p>
<p>Fortunately, after days of searching, I found the workaround for OS 2.2.1 and below.</p>
<pre class="brush: cpp">
    CGRect frame = navController.view.frame;
    frame.origin.y = 0.0;
    navController.view.frame = frame;
</pre>
<p>Answer taken from <a href="http://www.iphonedevsdk.com/forum/iphone-sdk-development/4225-navigation-controller-20px-short.html">iphonedevsdk.com</a>.</p>
<p>Hope this helps!</p>

			<content:encoded><![CDATA[<p>I had high hopes when I saw the news which said &#8220;<a href="http://gmailblog.blogspot.com/2009/05/tasks-now-in-calendar-too.html">Tasks, now in Calendar too</a>&#8221; from the <a href="http://gmailblog.blogspot.com/">Gmail Blog</a>. I have always been searching for a decent TODO app nicely integrated with my other appointments.</p>
<p>Unfortunately, when I checked the Calendar application from our Google Apps Standard, the link was not there. I then checked the original Google hosted Calendar application and saw the link there.</p>
<p>I wonder when this will be available in Google Apps, or maybe this is already available in the Business Edition? Please let me know if you are able spot this new feature in any of your Google Apps site.</p>

			<content:encoded><![CDATA[<p>We currently have an application in Groovy/Grails/Java that we&#8217;re slowly porting to PHP (for more affordable hosting costs).</p>
<p>We encountered a problem when we needed to convert one of our routines for writing out a binary file. We were using Java&#8217;s DataOutputStream.writeUTF(String) method and had a hard time trying to write binary data in PHP.</p>
<p>After much research on the web, we found a method in PHP called <a href="http://www.php.net/pack">pack()</a>. Below is our PHP implementation of Java&#8217;s DOS.writeUTF(String).</p>
<pre class="brush: php">
	public static function writeUTF($string) {
		$utfString = utf8_encode($string);
		$length = strlen($utfString);
		print(pack(&quot;n&quot;, $length));
		print($utfString);
		flush();
	}
</pre>
<p>We don&#8217;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.</p>
<p>Please checkout the <a href="http://www.php.net/pack">pack(</a>) documentation for more details.</p>

			<content:encoded><![CDATA[<p>Last week, a friend of mine asked me about my opinion about keeping design documents simple. What follows is a quote from the <a href="http://www.agilemodeling.com/essays/barelyGoodEnough.html">Agile Modeling article</a> he sent me over Skype.</p>
<blockquote><p>One of the more controversial concepts in Agile Modeling is that <a href="http://www.agilemodeling.com/essays/whenIsAModelAgile.htm">agile models</a> and <a href="http://www.agilemodeling.com/essays/agileDocumentation.htm#WhenIsADocumentAgile">agile documents</a> are sufficient for the task at hand, or as I like to say they are &#8220;<a href="http://www.agilemodeling.com/essays/barelyGoodEnough.html">just barely good enough (JBGE)</a>&#8220;.  In this article I make the following critical points about a model or document (an artifact) being just barely good enough</p></blockquote>
<p>This reminded me of a quote from Einstein which says &#8220;Everything should be made as simple as possible, but no simpler&#8221;.</p>
<p>This <a href="http://en.wikiquote.org/wiki/Albert_Einstein">Einstein Wiki Quote entry</a> also mentions that it is likely that the KISS (Keep it Simple Stupid) Agile methodology principle also originated from the same idea.</p>
<p>I didn&#8217;t get to read the whole article, but overall I agree with the concept.</p>
