Ballmer – really? Why don’t you do something productive like develop a product that people actually want to buy and use? So glad I ditched my Windows Mobile piece of junk and got an Android phone instead. Still not perfect but light years ahead in terms of usability – ease of use and flexibility are off the charts compared to Windows Mobile. Steve – maybe you should control yourself and think about that for a second instead of making a complete ass of yourself.
Android Marketplace – sell apps or free apps with ads?
There’s been some discussion online from Android application developers comparing their monthly income of Android apps vs iPhone apps. The iPhone has such a massive user base at this point that it’s hard to make these comparisons, but what I find interesting is whether to make money from selling your apps or give them away free and include banner apps inside them. If sales are currently low on the Android marketplace then you’re not going to get rich selling 99c apps, but are you going to do any better with free apps including banner ads? Here’s an interesting discussion <a href="http://www.4feets.com/2009/02/selling-apps-or-running-ads/"here, and here’s another comparison from an established iPhone and Android developer.

Software RAID support on Linux
Good RAID FAQ on Linux here.
Walkthrough on setting up a software RAID array here
Check RAID status:
<code>/sbin/mdadm --detail /dev/md0</code>
Or check with this:
<code>sudo cat /proc/mdstat</code>
This is what a good status will look like:
<code>
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md1 : active raid1 sdb5[0] sdc5[1]
1485888 blocks [2/2] [UU]
md0 : active raid1 sdb1[0] sdc1[1]
242709888 blocks [2/2] [UU]
unused devices: <none>
The [UU] (I think) indicates the status of both drives in the array, and both are Up
Removing drives: sudo mdadm /dev/md0 -r /dev/sdb1
Adding drives back to the array: sudo mdadm /dev/md0 -a /dev/sdb1
