Mac: AppleIntelCPUPowerManangement Kernel Panic

Mac: AppleIntelCPUPowerManangement Kernel Panic
After upgrading from Mac OS X Mavericks 10.9.2 to 10.9.3, my machine (HP Probook 4530s) ran into AppleIntelCPUPowerManangement Kernel panic, and to my surprise none of the boot flags helped me to boot into the system.
I decided to do a fresh install, but even booting from USB resulted the same. Then I decided to remove AppleIntelCPUPowerManangement.kext, but I can't even access terminal.

Here's the solution:
My machine dual boots Windows and Mac.

  1. I logged into Windows
  2. Installed MacDrive, trial version
  3. Rebooted into windows and opened the drive on which Mac is installed
  4. Did two things, don't know which one helped:
Opened /Extra/org.chameleon.Boot.plist with a text editor and added the following code:
<key>GenerateCStates</key>
<string>No</string>
<key>GeneratePStates</key>
<string>No</string>
And deleted AppleIntelCPUPowerManangement related kexts from this directory:
/System/Library/Extensions/
I found two kext folders related to it and deleted both.

Rebooted without any boot flags and voila. It worked.

JavaScript - Singleton Pattern

The singleton design pattern is probably the simplest and most common pattern in JavaScript. So why should you use the singleton pattern? Encapsulation of members & functions Creates its own Namespace A singleton is a single instance object Encourages code reuse Improves readability because you can logically organise your code The point of a singleton is to only have one instance. A shopping cart is a good example of something that you may want only a single instance of at one time. The simplest form of Singleton is an object literal. This loose form of Singleton cannot be instantiated. All of the members are now accessible through the Singleton variable, accessible through dot notation. var myCart = {     self: this ,     totalCost: 0,     totalQty: 0,     cart: {},     getCart: function (){ },     updateCart: function (){ } }; alert( "Total cost: ...

Find an old archived link on web

In recent past, I'm need of a tool, to which the provider no longer provides the link to download. Previously I've blogged about Openlogic , which serves this purpose. Openlogic contains unofficial fork of the original repository, and to be precise, I haven't found the tool I'm in search of. I found Internet Archive : Wayback Machine , while searching for it. It has got 412 billion stored pages and you may look into older versions of any website or you can get link to any software/tool which used to be a website. All you have to do is, provide a link or part of a link to search. For example, to know how my website used to be in 2013, just type http://www.thechaithanya.com and you can see a calender with some of the dates highlighted, on which they had the snapshot of my website. You can even provide a part of link. For example, to get the link of older version of Android ADT, search using http://dl.google.com/android/adt/* You can find a set of links and...
