If you are developing for Android, you probably have already abandoned the emulator that comes with Android SDK, and are testing and debugging on a real device. I cannot blame you - the emulator is awfully slow. Well I have good news for you - you can speed it up, if you are using uX system (Unix like - Linux, Mac OS X, BSD). The trick is very simple - and I suppose some of you have already activated it - mount /tmp folder into memory.

I had encounter several times that when using MaxOS X Lion, when I try to unlock system preferences (usually for setting user access, privacy settings, etc) - the unlock icon does not respond - does nothing.

Well - google-ing all over - I found my solution. Just open terminal and type the following 2 commands:

rm -rf ~/Library/Preferences/com.apple.HIToolbox.plist
sudo killall -9 securityd

Enjoy~
