The first bug was the background always turned black while scrolling which with black text on a white background washed out the text.

After resolving this by setting the background color, the 2nd bug which was very persistent was constant garbage collection while scrolling through the listview. Even if there were only 30-40 items, the garbage collection in logcat seemed awfully high.

After researching these issues I came across the key java commands to help clear them up. There were many helpful posts on stackoverflow.com, but the most helpful I link below.

The Java commands essentially set the listview background to white, matching the rest of the viewpager. The second Java command sets the Cache Color Hint which tells the listview which color to use while scrolling and animating the fade in/out at the top/bottom of the listview.

The commands are:
listView = (ListView) this.findViewById(R.id.listview);
listView.setBackgroundColor(Color.WHITE);
listView.setCacheColorHint(Color.WHITE);

Having already created the software “FAKERAID” partition using dmraid this guide will cover how to map the partition over as the main /home directory. Following is a simple set of commands to run:
cd /
sudo -s -H
mv /home /home2
mkdir /home
sudo gedit /etc/fstab
(at the bottom add)
/dev/mapper/isw_cbgddidiaj_RAID2p2 /home ext4 defaults 0 0
mount -a
*there are multiple ways to move the data from the old home2 directory to the new home directory*
cp -R /home2/* /home/
rm -r /home2
exit

Most of these steps are taken and adapted from this guide: Ubuntu Wiki Raid

1) Decide where to move the Chrome cache location to. I’ve picked the following location: /tmp/chrome.
This directory, /tmp/chrome will need to be created on boot and properly setup.
On Ubuntu 11.04 and probably older versions, this can be simply done in the /etc/rc.local file as follows:
sudo gedit /etc/rc.local
Add the following lines:
mkdir /tmp/chrome
mount -t tmpfs -o size=1024M,mode=0744 tmpfs /tmp/chrome/
chmod 777 /tmp/chrome/ -R

There are two ways to accomplish the next and last step. One is to create a symlink between the default google cache directory and the new temporary cache directory in RAM. The second is to add a switch to the google chrome command line telling each instance of the application to use our newly created cache directory in RAM.
1) rm -rf ~/.cache/google-chrome
ln -s /tmp/chrome/ ~/.cache/google-chrome
OR
2) Change the default here: sudo gedit /usr/local/share/applications/google-chrome.desktop
Replace the line:
#Exec=/opt/google/chrome/google-chrome %U
with
Exec=/opt/google/chrome/google-chrome –disk-cache-dir=”/tmp/chrome/”

The only adjustment some might wish to make will be the size of the tmpfs partition created in RAM above. I set the size to 1024MB as I don’t ever want to have to worry about or adjust it. My system is currently running on 24GB of RAM so the above size should not be an issue with the current system limitation.

I’m using an EVGA NVIDIA GeForce GTS 450 graphics card. I used the official NVIDIA drivers and the NVIDIA X Server Settings program. The best configuration I could achieve, was a separate instance of X Windows on each display. The only issue was I couldn’t move applications between them, which turned out to be a hassle as I’m used to moving windows/applications back and forth.

I ended up setting my NVIDIA X Server to clone the display on the second monitor. When I boot into Ubuntu classic w/o Unity, the second display automatically becomes an extended desktop. This would have been my final solution except I had already become accustom to using Unity. When I would boot into Unity, each display became an individual X server.

There is an application, disper, which cleared up all my issues. Now, when I boot into Ubuntu with Unity my displays are cloned. I open the terminal and type disper -e, which automatically detects the max resolution on the displays and extends my desktop!

The commands to grab disper and a nice disper indicator to fit in the top menu bar of Unity:
sudo add-apt-repository ppa:disper-dev/ppa
sudo add-apt-repository ppa:nmellegard/disper-indicator-ppa
sudo apt-get update
sudo apt-get install disper disper-indicator

If you want to allow disper-indicator to start every time Ubuntu starts, the directions are very simple on Ubuntu 11.04:
Go to System Settings (located at the bottom of shutdown button menu)
Open “Startup Application”
Click the Add button and type “disper-indicator” without the quotes in both name and command fields. Click the Add button and then Close.
On the next reboot the indicator will automatically be started!

It works great for me and hopefully this will save some time searching for an extended display solution using an NVIDIA card on Ubuntu 11.04 with Natty.

For all you wanting to add kernel version information to your android applications, here is the java code function copy/pasted from AOSP (Sorry, spacing is lost):

private String getFormattedKernelVersion() {
String procVersionStr;

try {
BufferedReader reader = new BufferedReader(new FileReader(“/proc/version”), 256);
try {
procVersionStr = reader.readLine();
} finally {
reader.close();
}

final String PROC_VERSION_REGEX =
“\\w+\\s+” + /* ignore: Linux */
“\\w+\\s+” + /* ignore: version */
“([^\\s]+)\\s+” + /* group 1: 2.6.22-omap1 */
“\\(([^\\s@]+(?:@[^\\s.]+)?)[^)]*\\)\\s+” + /* group 2: (xxxxxx@xxxxx.constant) */
“\\((?:[^(]*\\([^)]*\\))?[^)]*\\)\\s+” + /* ignore: (gcc ..) */
“([^\\s]+)\\s+” + /* group 3: #26 */
“(?:PREEMPT\\s+)?” + /* ignore: PREEMPT (optional) */
“(.+)”; /* group 4: date */

Pattern p = Pattern.compile(PROC_VERSION_REGEX);
Matcher m = p.matcher(procVersionStr);

if (!m.matches()) {
Log.e(TAG, “Regex did not match on /proc/version: ” + procVersionStr);
return “Unavailable”;
} else if (m.groupCount() < 4) {
Log.e(TAG, “Regex match on /proc/version only returned ” + m.groupCount()
+ ” groups”);
return “Unavailable”;
} else {
return (new StringBuilder(m.group(1)).append(“\n”).append(
m.group(2)).append(” “).append(m.group(3)).append(“\n”)
.append(m.group(4))).toString();
}
} catch (IOException e) {
Log.e(TAG,
“IO Exception when getting kernel version for Device Info screen”,
e);

return “Unavailable”;
}
}

Did a bit of research but never ended up having the need to implement.

The fix for the error is very simple. Two lines need to have a small value changed before the binary is compiled.
The actual edits are displayed, highlighted in yellow – http://cvs.eggheads.org/viewvc/eggdrop1.8/src/tclhash.c?r1=1.3.2.3&r2=1.3.2.4&diff_format=l
For more detailed information surrounding the issue, there is a great thread – http://forum.egghelp.org/viewtopic.php?p=97173#97173

After making the changes to the tclhash.c file in the src directory, simply compile and it should be fixed! Hope this helps somebody save some time as it took me a little while to track down the issue through all the threads and posts!

The error output before patching the issue is as follows:

Google Developer Comments regarding Shell Access:
Android Developer stating su is no longer supported
Android Developer stating shell commands are no longer supported

Very helpful open source toolset designed by Stericson to provide basic root commands for any Android Application:
RootTools – gives Rooted developers easy access to common rooted tools

Shell Access from Android Application Code Examples
Example how to request root access in your application
Example using su shell to execute reboot
Complex example with lots of code for accessing the shell through an application

My application WiMAX Keys Check – Market – Github – uses root shell access two times:
Simple Method to Verify Root Access
Simple Method to Read in Raw Partition Data

While in windows, START > Control Panel > Administrative tools or
START > run > compmgmt.msc and press enter.
Open Disk management
Locate the recovery partition (usually smaller and at the end of the disk).
Right click on the partition and mark partition as Active.

Reboot and by pressing F11, should be able to now boot the recovery partition and restore the Compaq Laptop.
This worked for me on a Compaq Presario C500.

Good luck!

I wanted to know what all of these different calls would return on my HTC EVO. Instead of having to write a program for these values, every time I needed to know, I figured I should write one program and log the output for reference.

In the hope somebody else might find the output helpful, I’m posting it here. If nothing else it will server as a great personal reference point.

I didn’t run all the functions available, but I picked the most important ones which seemed relevant.

Directions for a Hard Reset on a Sprint HTC Touch Pro:

1. Turn the device off (Some directions indicate leaving the device on, for Sprint this is not true)
2. Hold the volume down and enter key (enter key is center of the d-pad)
3. Press and hold the Power On key while still holding the volume down and enter key.
4. Within a few seconds there will be a prompt, confirming the complete deletion of all data.  Release the volume down, enter and power keys.  At this prompt, press the volume up key and all data will be deleted.
5. Hard Reset has now been completed.  The phone will restart, prompt for screen alignment, provide a tutorial, HTC and Sprint will install their extra software, phone will restart and everything should be good to go!

Near the top of the index.php file, before the line of code,  which will look similar to:

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

 insert the following line:

<?php if (is_front_page()) { query_posts(“cat=3″); } ?>

The number 3 will need to be changed to the categories ID. This can be found under the admin->posts->categories page. Hover the cursor over the category link and in the status bar it will display cat_ID=x. X will be the category ID to substitute into the line of code above.

I wasn’t able to find a setting, but I was able to find some code, link to original code below, to insert into the index.php and single.php files for the theme.  I put the code after the content is displayed. The code shows a small dynamic line at the end of each post with the original posting date and then the last updated date if is greater than 24 hours from the original posting date. 

It displays as follows:  This entry was posted on August 13th, 2009 at 4:23 pm and last updated on August 18th, 2009 at 12:57 pm

The code which needs to be added to the relative files, index.php and single.php for the theme I’m using, is as follows:

<p><small>
This entry was posted on <?php the_time(‘F jS, Y’) ?> at <?php the_time() ?>      
<?php $u_time = get_the_time(‘U’);
$u_modified_time = get_the_modified_time(‘U’);
if ($u_modified_time >= $u_time + 86400) {
echo “and last updated on “;
the_modified_time(‘F jS, Y’);
echo ” at “;
the_modified_time(); } ?>
</small></p>

Scientists and researches have been divided on how much radiation the body can tolerate being emitted from a cell phone.

The FCC limits Specific Absorption Rate (SAR) measured in watts per kilogram (W/kg) for partial-body exposure including the head to 1.6 W/kg. Generally the lower the SAR the lower the health risk posed by the cell phone.
