Insufficient storage available when updating apps on my Android

When updating apps via the Play Store, some apps will fail to update giving the ‘Insufficient storage available’ even when there is plenty of storage space available.



Results from Googling the error show different causes for the failure to update. In my particular case, the problem has something to do with the apps cache.

To overcome this issue, I used an app called App Cache Cleaner to clear the cache of all apps. After cleaning the cache, updates that failed before can now be updated successfully.



High RAM Prices

I am thinking of building a new Haswell machine as a second ESXi lab to test the new Oracle Database 12c.  My current lab, a Nehalem rig that was built 4 years ago, will not be up to scratch this test because it has only 24GB of RAM, and the new Grid Infrastructure will need a minimum of 4GB RAM per cluster node.

Haswell will allow a maximum of 32GB RAM..

Just as I was writing the above, I thought to myself, why not ask Uncle Google if my Nehalem board can take 8GB sticks?  It turns out that some people already did fit their EX58 motherboards with 8GB sticks, and managed to get 48GB of RAM recognized! Maybe I don’t need Haswell after all.

But to buy RAM now is a bit hard on the wallet as RAM prices are ridiculous.  Last year, a 4GB DDR3 stick can be bought at RM60 but now it is RM100 per stick!

Should I buy now, or should I wait?

Testing Windows 8.1 using VirtualBox

Microsoft released a preview of the upcoming service pack to Windows 8, named Windows 8.1 and also codenamed Windows Blue.  As a user of Windows 8, I wanted to see what are the changes that could be expected when the update becomes live and therefore decided to fire up and test the new OS inside VirtualBox.

I downloaded the 64-bit ISO from this webpage.  The page also gave away a preview product key to be used.

Then, I created a new virtual machine inside VirtualBox using the default WIndows 8 configuration.  I then turned on both 3D and 2D acceleration support, and mounted the Windows 8.1 ISO to the virtual machine.  However, the virtual machine failed to boot with 0x000000C4 error.

0x000000C4 Error

Luckily, someone else had already come across this problem, and created a VirtualBox support ticket.  The solution can be found here, which requires an extra setting to be configured on the virtual machine.

"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" setextradata [VM_name] VBoxInternal/CPUM/CMPXCHG16B 1

VM_name should be set to the name you have given to the virtual machine.  This can be double-checked using the following command:

"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" list vms

Now the ISO booted fine, and the installation can begin.
