While developing REST services using Spring MVC, I would like render JSON &#39;pretty printed&#39; in development but normal (reduced whitespace) in production.

When using Spring MVC for REST, how do you enable Jackson to pretty-print rendered JSON?

They both seem to give me the same thing (the domain name currently executing the script).

So what&#39;s the difference (if any) and where should each be used?

I have some JavaScript code that gives this error

```none
Uncaught TypeError: Cannot read property &#39;value&#39; of undefined
```

Code

    var i1 = document.getElementById(&#39;i1&#39;);
    var i2 = document.getElementById(&#39;i2&#39;);
    var __i = {&#39;user&#39; : document.getElementsByName(&quot;username&quot;)[0], &#39;pass&#39; : document.getElementsByName(&quot;password&quot;)[0] };
    if(  __i.user.value.length &gt;= 1 ) { i1.value = &#39;&#39;; } else { i1.value = &#39;Acc&#39;; }
    
    if(  __i.pass.value.length &gt;= 1 ) { i2.value = &#39;&#39;; } else { i2.value = &#39;Pwd&#39;; }

What does this error mean?

If I have a `.html` file in a GitHub repository, e.g. for running a a set of JavaScript tests, is there any way I can view that page directly—thus running the tests?

For example, could I somehow actually see the test results that would be produced by [the jQuery test suite][1], without downloading or cloning the repo to my local drive and running them there?

I know this would basically put GitHub in the static content hosting business, but then again, they just have to change their mime-type from [`text/plain`][2] to `text/html`.

Can I run HTML files directly from GitHub, instead of just viewing their source?

I want to URL encode this:

    SELECT name FROM user WHERE uid = me() 

Do I have to download a module for this? I already have the request module.

How do I URl encode something in Node.js?

I want to remove all special characters except space from a string using JavaScript.

For example,
`abc&#39;s test#s`
should output as
`abcs tests`.

The (now defunct) page http://stream.twitter.com/1/statuses/sample.json used to return a continuous and endless stream of JSON data.

I&#39;d like to process it using jQuery (or JavaScript, but preferably jQuery) inside my own web page to be able to display visual effects based on the live feed of tweets.

Since as far as I know the jQuery `parseJSON` function will only execute the callback function after all the data has been sent by the server, but this is actually a continuous stream of data. How can I process the data &quot;as it happens&quot; but still keep the connection running?
