[Yahoo][2] or [MSN][3].

C#:

    //这里显示一些代码，在正文显示中会自动识别语言，进行代码染色，这是一段C#代码
    public class Blog
    {
         public int Id { get; set; }
         public string Subject { get; set; }
    }

Python:

    keywords = ["dsaa","Asd","sadc","Gdfd","gdfdd","gaf","gabdddddd","eg"]
    print dict([(i[0],list(i[1])) for i in groupby(sorted(keywords),lambda    x:x[0].lower())])

Javascript:

    /**
     * nth element in the fibonacci series.
     * @param n >= 0
     * @return the nth element, >= 0.
     */
    function fib(n) {
        var a = 1, b = 1;
        var tmp;
        while (--n >= 0) {
            tmp = a;
            a += b;
           b = tmp;
        }
        return a;
    }

    document.write(fib(10));
