When Linux Hangs or Completely Freezes


When Windows hangs itself we all know what to do right? Were just reaching for the combination [Ctrl]+[Alt]+[Del] (Control Alt Delete). But if you try this in Linux nothing happens (in some distributions, like Ubuntu, you actually get the menu for shutting down your system, but this don’t work when your system hags or freezes).
So what to do?
There is 3 keyboard combinations every Linux user should remember (or write down). But before we begin I want you to understand some of the signs I use: If a symbol is surrounded by [ ] means that it is a button or key on your keyboard. +means that you have to hold the keys down at once. And > means that you have to click the buttons one by one, remember that you have to press each key for 2-3 seconds. Now that you have learned this we can move on to the commands:
Fist you have the combination [Ctrl]+[Alt]+[BackSpace] (backspace is the [←] over[Enter]) that restarts X or GDM (you will be logged out), and you can kind of call it Linux’s Control Alt Delete equivalent. This command gives your programs time to make emergency backups of unsaved files (for example if you writing on a document in Open Office) and it  prevents that you get a file system error during the crash.If you use Ubuntu or a distribution based on Ubuntu you will have to use[Alt]+[PrtSc]+[K] (PrtSc = Print Screen) instead, but you should note that some Ubuntu based distros (like Linux Mint) still use the universal [Ctrl]+[Alt]+[BackSpace].
But what to do if this combination doesn’t work? 
Then you have to use something called Magic SysRq Keys. In short they are keys which allows you to perform various commands regardless of the system’s state, like in this case get the system to recover from a freeze. Note that these keys wont work if your system is in kernel panic. Like I said there are tree combinations that you will have to remember and since we have already learned one, there are two to go:
This command will get your freezed system to restart safely:
Hold [Alt]+[PrtSc] then type [R]>[E]>[I]>[S]>[U]>[B] (press each key for 2-3 seconds). In short the keys mean: unRaw (take control of keyboard back from X), tErminate (send SIGTERM to all processes, allowing them to terminate gracefully), kIll (send SIGKILL to all processes, forcing them to terminate immediately), Sync (flush data to disk), Unmount (remount all filesystems read-only), reBoot (restart).
A common idiom to perform a safe reboot of a Linux computer which has otherwise locked up, the QWERTY (or AZERTY) mnemonic "Raising Elephants Is So Utterly Boring", "Reboot Even If System Utterly Broken" or simply remembering the word "BUSIER" backwards, is often useful.
This command will get your freezed system to shut down in a safe way:
Again hold [Alt]+[PrtSc] then type [R]>[E]>[I]>[S]>[U]>[O] (press each key for 2-3 seconds). These keys mean: unRaw, tErminate, kIll, Sync, Unmount , shutdOwn (does it really need an explanation?).

How to fix the iOS 4.3 battery drain issue

Not so long ago, we shared with you the not so good news of iOS 4.3 severely draining down the precious battery life of the compatible iPod touch and iPhone models. Today, we have a possible fix for the painstaking issue thanks to @iThinkiTweeted. More on this after the jump.

Battery Drain

You can fix (temporary fix if you may) the serious battery drain issue by resetting your network settings, for which you will Go to Settings > General > Reset > Reset Network Settings.

Andrew, who suggested the fix applied it with success on his iPhone 4. We ourselves can’t verify this as we haven’t updated our iDevice to iOS 4.3 for jailbreak and graphical glitch reasons. If you are running iOS 4.3 on your iPhone or iPod Touch, and can verify this for us, we will be very thankful to you.

How to disable Facebook Photo Theater mode


Last night, a friend of mine asked me for a way to get rid of the not so well received Facebook Photo Theater mode. While I helped him, I thought why don’t share the Facebook Photo Theater pain killer with you guys as well. Get the solution after the break.

If you do your browsing using Chrome, then all you need to do is install the Revert Facebook Photo Viewer extension for Chrome and you are good to go. The extension doesn’t require any interaction from you whatsoever and does its work silently and efficiently.

Facebook Photo Theater View went live in February 2011 and as many of you know lets you view photos in Theater mode which is basically a picture with an annoying black background.
