A number of websites and online services, which were previously operational, have stopped working in Pakistan since 1st Feb (verified on PTCL and Cybernet, in Karachi). The sites appear broken and their services, if any, are not working as intended. This could be a temporary glitch, or it could be a side-effect of the Pakistani government/PTA banning websites and IP addresses.

Following are the sites/services I have come across that are not working entirely or partially from Karachi, Pakistan (if you come across any others, tweet them to @sawant):

• The Guardian (url 2)
• Website: Not loading/Appears blocked - it starts working sometimes
• Foursquare
• Website: Loading partially/Appears broken
• Services: ?

New Wave of Inaccessible/Blocked websites and services

A number of websites and online services, which were previously operational, have stopped working in Pakistan since 1st Feb (verified on PTCL, Cybernet and Multinet, in Karachi). The sites appear broken and their services, if any, are not working as intended. This could be a temporary glitch, or it could be a side-effect of the Pakistani government/PTA banning websites and IP addresses.

Following are the sites/services I have come across that are not working entirely or partially (report any other sites/services in the comments or tweet them to @sawant):

var power = function(base, exp) {
  if (exp == 1)
    return base;
  else
  	return base * power(base, exp-1);

We’ve seen that % (the remainder operator) can be used to test whether a number is even or odd by using % 2 to check whether it’s divisible by two. Here’s another way to define whether a positive whole number is even or odd:

Zero is even.

One is odd.

For any other number N, its evenness is the same as N - 2.

Define a recursive function isEven corresponding to this description. The function should accept a number parameter and return a Boolean.

Write a range function that takes two arguments, start and end, and returns an array containing all the numbers from start up to (and including) end.

Next, write a sum function that takes an array of numbers and returns the sum of these numbers. Run the previous program and see whether it does indeed return 55.

As a bonus assignment, modify your range function to take an optional third argument that indicates the “step” value used to build up the array. If no step is given, the array elements go up by increments of one, corresponding to the old behavior. The function call range(1, 10, 2) should return [1, 3, 5, 7, 9]. Make sure it also works with negative step values so that range(5, 2, -1) produces [5, 4, 3, 2].

The == operator compares objects by identity. But sometimes, you would prefer to compare the values of their actual properties.

Write a function, deepEqual, that takes two values and returns true only if they are the same value or are objects with the same properties whose values are also equal when compared with a recursive call to deepEqual.

To find out whether to compare two things by identity (use the === operator for that) or by looking at their properties, you can use the typeof operator. If it produces "object" for both values, you should do a deep comparison. But you have to take one silly exception into account: by a historical accident, typeof null also produces "object".
