You can’t (usefully) compare strings using != or ==, you need to use strcmp: The reason for this is because != and == will only compare the base addresses of those strings. Not the contents of the strings themselves.
Pretty-printing is implemented natively in JSON.stringify(). The third argument enables pretty printing and sets the spacing to use: If you need syntax highlighting, you might use some regex magic like so: See in action here: jsfiddle Or a full snippet provided below: Show code snippet

Currently I have an input box which will detect the URL and parse the data. So right now, I am using: The problem is, when I enter a URL like www.google.com, its not working. when I entered http://www.google.com, it is working. I am not very fluent in regular expressions. Can anyone help me?
I see the problem. It’s this line: The == operator has precedence over the = operator. Look at the way you have the parentheses structured on that expression a bit more carefully to see what I mean. sockfd is getting initialize to “0” as a result of being assigned a boolean expression (socket(…) == -1). … Read more

In Ruby and Perl 6 this has been called “splat”, and I think most people from those communities will figure out what you mean if you call it that. The Python tutorial uses the phrase “unpacking argument lists”, which is long and descriptive. It is also referred to as iterable unpacking, or in the case of **, dictionary unpacking.
Using multiple threads on CPython won’t give you better performance for pure-Python code due to the global interpreter lock (GIL). I suggest using the multiprocessing module instead: Note that this won’t work in the interactive interpreter. To avoid the usual FUD around the GIL: There wouldn’t be any advantage to using threads for this example anyway. You want to … Read more
