OS X Lion – Remove an app from Launchpad

General Launchpad thoughts

I continue my tips regarding OS X Lion. As I said in my OS X Lion walkthrough, Lion come with a very iOS-ish application launcher : Launchpad. Out of the box, it is automatically populated with every application you have and application you download from the Mac App Store are added there too.

Although I keep on thinking it is a useless feature for power users, newcomers will surely find this useful, and it will help switchers to find their applications. As I was cleaning my machine I tried to rearrange Launchpad by making folders and then I discovered that you can’t easily remove a shortcut to an application (except the ones coming from the Mac App Store which are uninstalled when you remove their icons).

Let me remove things !

By digging around, I found that Launchpad stores its preferences in a SQLite database, that you can explore and manipulate using the sqlite3 command line program.

Please notice that the steps described here might make your Launchpad unusable, so please backup every file you change in case something goes wrong !

Update ! Easy technique, use Launchpad-Control which is a preference pane allowing to visually hide / show icons on Launchpad. I detail here the step involved for the records.

Playstation 3 – a random tale…

So, here we are, from fail0verflow team‘s announce at 27c3, Playstation 3 security is no more. It’s a good thing for homebrews, the return of otherOS and media center happyness. As from many of you might know, GameOS is exposed since the famous PSGroove thing. But we still were not able to boot on totally hand made code. The thing the team found is a critical error in implementing their random number generator used in signing code : it returns a constant value (those who are not afraid with mathematics can have a look there to understand). To be clear, we got the way to sign arbitrary code, and Sony can’t do anything about this !

The bad thing is it surely will bring a lot more piracy on the PS3, I hope Sony will still be able to detect altered game to keep online entertainment possible !
