The International Obfuscated C Code Contest is a contest for people to write unusual C code to stress test the C compiler. It is a very interesting competition where people submit their C codes for judging. In this entries I would like to highlight some winning entries which manage to organize their code as a very nice image yet meaningful to the content that the code generated ( like n! entry ). Enjoy!!!

IOCCC RAY

According to the author, the program below is a small ray-tracer and does not use any C keywords (shocked!) as a program using keywords when printing will need to use more ink because of the boldness of the keywords. You can also see the word IOCCC RAY hidden in the midst of the code. Very inspiring! More details about this winning entry could be found here

Recently I was working around with a lot of HTTP status code. Thinking this table will be useful for every web developer as references.

Filed under: Programming | 1 Comment

Table is a very basic thing in HTML and website building. Many times, when I encounter a table in my project, I usually need to find out a way to style the table to make it nice and be suitable with the website. Fortunately, a lot of techniques and designs of table are already available on the web together with tutorials teaching people to build a very neat and nice table. In this article, I would like to introduce those techniques and designs so that you can refer to when you need to apply one of them into your project.

Let’s start from neat & simple designs from http://fluidmind.org

FLUIDMIND.ORG

This design is a very simple design. However, it manages to change all the default border of a table and add in 1px border to make the table nice and neat to view.

This design improves from the first one by adding in the background color and make the table easy to see vertically.

This design improves the horizontal readability and enhances the view by making the header color outstanding from the rest of the table.

Using with keyword to shorten your code

“with” keyword becomes extremely handy when you need to use many attributes of an object without keep calling the object

var house = {
     paint: "blue",
     size: "big",
     hasYard: true,
     numberOfLivingRooms: 2,
     numberOfStoreRooms: 1,
     numberOfBedRooms: 4,
     numberOfKitchen: 3,
     masterArea: {
           hasBedRooms: true,
           masterAreaBedRooms: 3
    }
};

I believe most of you have heard about using XML to store data. However, using JSON object to store data in Javascript is the most convenient way as JSON object is native in Javascript programming. An example of JSON object is as following
