				<content:encoded><![CDATA[<p>I created a small script that will generate the required icon files and launch images  in PNG format for a default cordova / phonegap project.</p>
<p><del>Currently only icon files are supported, I am working on adding the splash / Launch images for iOS as well.</del></p>
<p>&nbsp;</p>
<p>Upload a square icon of preferably  512&#215;512 or bigger and you will receive a zip file with the required images as seen in the below screenshot.</p>
<p>Keep in mind that each time you visit this page, all uploaded and generated files are removed. So this might be problematic if many try to run this script at the same time (which I don&#8217;t expect).</p>
<p>Todo:<br />
Generate all required files according to the default directory layout as generated by cordova&#8217;s create script.</p>
<p>The script: <a href="http://arenddeboer.com/cordova/">http://arenddeboer.com/cordova/</a>.</p>
<p>Script source:<a href="/cordova_icon_gen_source.zip"> cordova_icon_gen_source.zip</a> (please share any updates or improvements you make)</p>

				<content:encoded><![CDATA[<p>Just a quick note because I couldn&#8217;t  find much info about this on the web.</p>
<p>After installing Ubuntu 12.04 and creating a simple RAID 1 mirror everything looked great, until after a reboot. I was unable to assemble the array with an error message like the above. It turned out I had to remove the package mdraid and it magically started working again. Hope it helps someone.</p>
<p>Thanks to Jonik for the info.</p>

<h3>Updated March 11, 2012</h3>
<p>This application enables WiFi Ad Hoc mode on supported Android devices.</p>
<p>WARNING &#8211; In a worst case scenario you may have to restore your device with a backup rom. If you are not ready to do so please don&#8217;t use this app.</p>
<h2>Reported to give <span style="color: #ff6600;">problems</span> on:</h2>
<ul>
<li>HP Touchpad running Cyanogen Mod 9 ICS</li>

<li>LG Optimus One (new update hopefully changes this)</li>
<li>GPAD M7206</li>
<li>Samsung I9003 Galaxy SL</li>
</ul>
<h2></h2>
<h2>Report statistics:</h2>
<p>Please keep in mind that these numbers are a rough estimate. I will try to filter out duplicate reports (users who send in reports multiple times from the same device)</p>
<p><iframe src="http://arenddeboer.com/wifiadhocenabler/index2.php" frameborder="0" width="100%" height="370px"></iframe></p>
<p>&nbsp;</p>
<h2>Features:</h2>
<ul>
<li>Enable WiFi Ad Hoc mode (and keep infrastructure)</li>
<li>Restore original settings</li>
</ul>
<h2>Issues:</h2>
<ul>
<li>No WiFi signal strength visible in taskbar</li>
<li>There are reports where WiFi completely stopped working (until a factory/hard reset).</li>
</ul>
<h2>Requires:</h2>
<ul>
<li>Root Access (Superuser)</li>
<li>BusyBox (don&#8217;t forget to actually use the BusyBox wrapper App to download the BusyBox binary!)</li>
</ul>

<p>Use at your own risk! Please create a rom backup before using this tool.</p>
<p>If you successfully enabled WiFi on your device, please press the &#8220;It Works&#8221; button to report it to me. I will add your device to the list of supported devices.</p>

<h2>Credits</h2>
<p>Szymon for creating the wpa_supplicant file that allows you to see Ad Hoc networks ( <a href="http://szym.net/2010/12/adhoc-wifi-in-android/">http://szym.net/2010/12/adhoc-wifi-in-android/</a>)</p>
<p>RootTools, a library that allows easy root related tasks: <a href="http://code.google.com/p/roottools/">http://code.google.com/p/roottools/</a></p>
<h2>The future</h2>
<p>It was fun working on this app, but it has proven to be difficult to make something that enables Ad Hoc on a wide spectrum of Android devices. Therefor I will no longer be updating the application and will remove the &#8220;report to developer&#8221; option. My next project:  running Linux native on my Galaxy Tab P7510.<br />
Starting point will be this thread by <a href="http://forum.xda-developers.com/member.php?u=3369526">poitee</a> -&gt; <a href="http://forum.xda-developers.com/showthread.php?t=1189251">http://forum.xda-developers.com/showthread.php?t=1189251</a></p>
<p>Thanks for all the feedback.</p>
<p>&nbsp;</p>
<h2>Update: March 4, 2012</h2>
<p>Version 1.8.3 is out.</p>
<p>Hopefully added the Asus Transformer Prime TF201 with ICS / Android 4 to the list of supported devices.<br />
Commands are now executed prefixed with busybox, hope this helps some of the &#8220;grep not found&#8221;  errors.</p>

				<content:encoded><![CDATA[<p>WordPress is a perfect blogging CMS, yet it is also flexible enough to be used for corporate / business sites. The only drawback is that the admin interface is geared towards the blogger. For example the <em>Posts</em> and <em>Comments</em> menu items aren&#8217;t needed when all you use is <em>Pages</em>. To present a clean and slimmed down interface to my WordPress clients I decided to create a plugin which allows you to hide certain backend menu items. This is the menu page without hiding any menu items:</p>
<p><a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2011/07/before1.png" rel="lightbox[269]"><img class="alignnone size-full wp-image-277" title="Wordpress menu without Clean Admin Menu in action" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2011/07/before1.png" alt="" width="530" height="491" /></a></p>
<p>&nbsp;</p>
<p>This is after hiding all items:<br />
<a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2011/07/after1.png" rel="lightbox[269]"><img class="alignnone size-full wp-image-278" title="Wordpress menu with Clean Admin Menu in action" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2011/07/after1.png" alt="" width="529" height="409" /></a></p>
<p>Just go over to<a href="http://wordpress.org/extend/plugins/clean-admin-ui/"> http://wordpress.org/extend/plugins/clean-admin-ui/</a> or search for it in your WordPress plugin section using the terms admin, menu, ui.</p>
<ul>
<li>Requires WordPress 2.8 or higher</li>
<li>Added option to hide Media menu item.</li>
<li>I am thinking of creating a localized version</li>
</ul>
<p>Let me know if there are more options you would like to see.</p>

<p>Note that these prices are ex FAT and I ordered them in larger volumes, ymmv.</p>
<p><a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0242.jpg" rel="lightbox[179]"><img class="alignnone size-medium wp-image-191" title="components overview" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0242-300x179.jpg" alt="components overview" width="300" height="179" /></a></p>
<p>Poor man&#8217;s (ms-paint) diagram<br />
<a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/schema.png" rel="lightbox[179]"><img class="alignnone size-full wp-image-195" title="schema" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/schema.png" alt="" width="640" height="400" /></a></p>
<p>Step 1: saw a piece out of the veroboard, approximately 17 x 40 mm (the board below is too long, approx 65 in length)<br />
<a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0229.jpg" rel="lightbox[179]"><img class="alignnone size-medium wp-image-180" title="Veroboard" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0229-300x179.jpg" alt="Veroboard" width="300" height="179" /></a></p>
<p>Step 2: Solder the two tantalum bead capacitors on the voltage regulator. Be careful to not overheat the components, polarity is essential. Long leg is positive.<br />
Place the 22uF Capacitor on the right,  the .47 uF on the left. Negative polarity combined in the middle.<br />
<a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0234.jpg" rel="lightbox[179]"><img class="alignnone size-medium wp-image-185" title="step 2" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0234-300x179.jpg" alt="" width="300" height="179" /></a><br />
Step 3: prepare capacitor C1 with the heat-shrink tubing, bend the pins (long leg = positive) as seen in the photo. Keep the legs as long as possible for flexible placement of this component inside the ABS case.<br />
<a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0232.jpg" rel="lightbox[179]"><img class="alignnone size-medium wp-image-183" title="capacitor" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0232-300x179.jpg" alt="capacitor" width="300" height="179" /></a><br />
Step 4: place the components on the veroboard:<br />
Looking at the first picture below; the middle three parallel stripes on the board serve as the main electrical paths for the components. The stripe on the left corresponds with the positive side on the diagram.<br />
- C1: the long leg (+) should be placed on the left of the three middle stripes. The short leg should go in the middle. (in reference to picture 1)<br />
Picture 1:<br />
<a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0244.jpg" rel="lightbox[179]"><img class="alignnone size-medium wp-image-200" title="step 4 picture 1" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0244-300x179.jpg" alt="step 4 picture 1" width="300" height="179" /></a></p>
<p>The bridge rectifier output legs should be placed as follows: The + (as indicated on the component) should go on the left of the three middle strips.<br />
The &#8211; (negative) output should go in the middle. The AC input legs can be placed on the outer stripes of the board. (left and right in reference to picture 1)</p>
<p><a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0245.jpg" rel="lightbox[179]"><img class="alignnone size-medium wp-image-201" title="step 4 picture 2" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0245-300x179.jpg" alt="step 4 picture 2" width="300" height="179" /></a></p>
<p><a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0246.jpg" rel="lightbox[179]"><img class="alignnone size-medium wp-image-202" title="step 4 picture 3" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0246-300x179.jpg" alt="step 4 picture 3" width="300" height="179" /></a></p>
<p>And finally solder the voltage regulator as well.</p>
<p><a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0247.jpg" rel="lightbox[179]"><img class="alignnone size-medium wp-image-203" title="step 4 picture 4" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0247-300x179.jpg" alt="step 4 picture 4" width="300" height="179" /></a></p>
<p><a href="../wp-content/uploads/2010/06/IMAG0254.jpg" rel="lightbox[179]"><img title="IMAG0254" src="../wp-content/uploads/2010/06/IMAG0254-179x300.jpg" alt="" width="179" height="300" /></a></p>
<p>Before going any further, check to see if it&#8217;s working properly.<br />
Prepare the cable that runs to the dynamo, and connect it on the input legs of the bridge rectifier. Polarity is of course of no concern as we are dealing with an alternating current. Connect the dynamo to this kit, swing the wheel and measure the output voltage on the + (Vout) and &#8211; leg of the output regulator.</p>
<p><a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0250.jpg" rel="lightbox[179]"><img class="alignnone size-medium  wp-image-205" title="test output 2" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0250-179x300.jpg" alt="test output 2" width="179" height="300" /></a></p>
<p><a href="../wp-content/uploads/2010/06/IMAG0256.jpg" rel="lightbox[179]"><img title="IMAG0256" src="../wp-content/uploads/2010/06/IMAG0256-300x179.jpg" alt="" width="300" height="179" /></a></p>
<p>We should measure around 5 Volts</p>
<p><a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0248.jpg" rel="lightbox[179]"><img class="alignnone size-medium  wp-image-204" title="Test output" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0248-179x300.jpg" alt="Test output" width="179" height="300" /></a></p>
<p>If it doesn&#8217;t work, carefully check the polarity of the capacitors and other components.</p>
<p>We can now safely cut the remaining component legs form the veroboard,  and bend C1 to fit inside the ABS case.</p>
<p>I connected the heat-sink using a <a href="http://en.wikipedia.org/wiki/Blind_rivet#Blind_rivets" target="_blank">blind rivet</a> this is ideal as it does not need any additional space (especially height).<br />
<a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0260.jpg" rel="lightbox[179]"><img class="alignnone size-medium wp-image-221" title="IMAG0260" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0260-300x179.jpg" alt="" width="300" height="179" /></a></p>
<p>Before connecting the cables, drill a small hole for the Cable Gland Locknut, connect the Cable Gland Locknut and route the wires through it.</p>
<p><a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0262.jpg" rel="lightbox[179]"><img class="alignnone size-medium wp-image-222" title="IMAG0262" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0262-300x179.jpg" alt="" width="300" height="179" /></a></p>
<p>Next, connect the USB A receptacle or if you like a mini or micro USB cable directly to the voltage regulator output legs. Connect the dynamo cable to the bridge rectifier.</p>
<p><a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0263.jpg" rel="lightbox[179]"><img class="alignnone size-medium wp-image-223" title="IMAG0263" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0263-300x179.jpg" alt="" width="300" height="179" /></a></p>
<p>In order for this whole package to fit inside the box, I had to saw one of the corners from the veroboard.</p>
<p><a href="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0266.jpg" rel="lightbox[179]"><img class="alignnone size-medium wp-image-224" title="IMAG0266" src="http://www.arenddeboer.com/wordpress/wp-content/uploads/2010/06/IMAG0266-300x179.jpg" alt="" width="300" height="179" /></a></p>
<p>When using the same ABS case as listed in the requirements section, be sure to cut the two screw holes at the bottom of the case for more room.</p>
<p>That&#8217;s pretty much it. I will seal the case of with a polymer resin, to make it water proof. Be sure to only do this after you are absolutely sure everything works.</p>

				<content:encoded><![CDATA[<p>This is an update on my previous post about a <a href="http://www.arenddeboer.com/bike-mounted-usb-charger/">hub-dynamo driven (USB) charger.</a><br />
A step by step guide is posted <a href="http://www.arenddeboer.com/diy-hub-dynamo-usb-charger/" target="_blank">here</a>: (still a work in progress)</p>
<p>The latest incarnation is a stripped down version of the original. I left out the input tuning C2, C3, R1 (see original post for the diagram) and replaced the 4 Schottky diodes with an integrated bridge rectifier. The Schottky diodes  are more efficient due to the lower forward voltage drop, but require more soldering and space.  This version now fits into a small ABS case. I hope to replace the fixed USB cable with a USB A receptacle (if it fits).</p>

<p>Visiting <a href="http://www.verisign.com/">verisign.com</a> you will see a one year Code Signing Certificate will set you back  US $ 499,-</p>
<p>According to Adobe&#8217;s Flash Builder documentation only Certificates from the big four CA&#8217;s are trusted:</p>
<p>&#8220;<em>A  developer can use any class-3, high-assurance certificate provided by   any CA to sign an Adobe AIR application. However, only ChosenSecurity,   GlobalSign, Thwarte, and VeriSign come pre-installed on most end user&#8217;s   machines (Mac OS X or Windows) and are trusted by the operating  systems.</em>&#8221;</p>
<p>These companies ask an amazing amount of money for a certificate, luckily there are better alternatives. The one I got was available for $75,- a year. This of course raises the question whether this certificate will be accepted, but I did found a couple of blog posts that reassured me this shouldn&#8217;t be a problem.</p>
<p>Hop over to <a href="https://author.tucows.com//">author.tucows.com</a>, register for an account and you will be able to purchase a Comodo Certificate through tucows.<br />
The process will take some time. You will have to email documents to proof  your business/person identity and they probably call you as well. After receiving the certificate and signing the AIR package I was able to install my signed software successfully on:</p>
<ul>
<li> Windows 7</li>
<li>Windows Vista</li>
<li>Windows XP</li>
<li>Mac OS X (10.6).</li>
</ul>
<p>Unfortunately Ubuntu Linux 10.04 fails to recognize/trust the certificate out of the box (thanks to Jaap for testing this)</p>

				<content:encoded><![CDATA[<p>This post is the second part from my &#8220;<a href="http://www.arenddeboer.com/windows7-system-recovery/">note to self</a>&#8221; on recovering my PC.</p>
<p><strong>The problem</strong></p>
<p>I have a 4 drive spanned RAID (raid0) volume where one of the drives mysteriously dropped from the volume, becoming a so called non-RAID member.  I was pretty sure I had not messed around with this now non-raid drive. Neither had I performed any write operations to this disk. This led me to the conclusion that somehow the software raid manager (Intel Storage Matrix) had decided the drive was no longer part of the volume, but the data must still be intact. Apparently the meta-data for each member used by the (software) RAID BIOS is located on each member drive. So if this meta-data could be restored, the entire volume could be restored. Armed with this knowledge I booted into the RAID BIOS, and removed the other 3 drives from the volume. This will give you an intimidating warning about losing all data, but at least with Intel RAID this only wipes the RAID meta-data from the drive. After  removing all drives, I recreated the exact same volume, in the exact same order (order is critical!)  Now after booting into Windows I was able to recover the partition with the excellent tool TestDisk which you can find here: <a href="http://www.cgsecurity.org/" target="_blank">http://www.cgsecurity.org.</a></p>
<p>Be sure to follow the <a title="TestDisk manual" href="http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step" target="_blank">manual.</a> In my case the partition didn&#8217;t show up using the quick-search, but after the more thorough  &#8220;Deeper Search&#8221;.</p>
<p>Many thanks go to Christophe GRENIER, the developer of TestDrive and the post from  &#8220;adamsap&#8221; on <a href="http://forums.extremeoverclocking.com/showthread.php?p=3329132#post3329132" target="_blank">forums.extremeoverclocking.com</a></p>
