Use Adsense for Search on WordPress
I have searched a few blogs in the hope to find a good way to use Adsense for Search to replace default WordPress search. All the solutions suck, they either ask users to add redundant plugins that doesn’t do the job at all or ways to create a static page to display search results. I got really fed up with these ’solutions’ and finally decide to make my own easy to implement method.
1. Create the Adsense for Search unit from adsense website (I don’t wanna write the steps here because Google has been doing a great job providing step by step guide to create the search unit).
2. When you complete the steps to create the unit on Adsense, you shall get two parts of the generated code, Search Box Code and Search Results Code, copy the Search Results Code.
3. Go to your blog admin, Create a Page called Search Results,
4. Paste the Search Results Code you just copied into the textarea.
5. Get the page id, the page id is the digits at the end of your edit page url, for instance, if the page editing url you are creating your Search Result page is http://www.yourblog.com/wp-admin/page.php?action=edit&post=739, then your post id is 739.
6. Publish the page.
7. Go to Design->Theme Editor, from the template pages, select Header.php, and search for the line similar to the one below:
wp_list_pages(’title_li=&depth=1′);
8. Change the line above to the one below and save the file:
wp_list_pages(’title_li=&depth=1&exclude=739′);
739 is a generic number, it’s the Search Page Result id.
9. Open your template file Sidebar.php, at the place you want the Search Box to appear, paste the Search Results Code at the area. And save the post.
10. Now you are done! It requires neither a static page (in the dynamic world, why need a stupid static page?) nor plugins. Just the simple implementation above! Hope this helps :)

Prototype Function Variable inside Observe
Posted by admin in JavaScript Library on November 28, 2008
If you are a user of JavaScript Framework Prototype, and use observe to handle event, you may face problem when you try to call function with variable inside the observe.
Let’s assume you have an HTML element with the id btn, you want to alert a custom message when it’s clicked, you might code it the following way:
function alertMessage(message) {
alert(message);
}
$('btn').observe('click', alertMessage('hullo world'));
this won’t work because it involves <strong>currying</strong>. Currying? What the heck is that? You may ask, ok, let me try to explain this:
Because <strong>alertMessage</strong> is a function and <strong>message</strong> is an argument, to write it in the observe event handler, we must produce a new function by combining function <strong>alertMessage</strong> and its argument <strong>message</strong>, this is called <strong>currying</strong>.
The bad news is that JavaScript doesn’t have a build-in curry method, but the good news is that Prototype has one! So to make the above script work, all you need to do is to add in the curry!
function alertMessage(message) {
alert(message);
}
$('btn').observe('click', alertMessage.curry('hullo world'));
For more about currying, check out the following two great Google book excerpts, one by Yahoo! Architect Douglas Crockford and another by Core Prototype developer Andrew Dupont.

CakePHP Solution for Warning: Cannot modify header information – headers already sent
If you are using CakePHP to develop your website, you may get the error message:
Warning: Cannot modify header information - headers already sent
This error is not uncommon, many people bump into this problem, especially for beginners. This error message makes the problem sound very serious, but the problem itself is not that complicated at how. By interpreting the message ‘literally’, you will find that the default error message instruct you to do something you have already done, for instance: create method in controller.
The actual problem is whitespace, yes, it must be somewhere, a whitespace is hiding somewhere, it can be at view, model or controller, it may not be in the file you are opening, because of the way CakePHP works, you might be editing several files before run the test, so the whitespace at the end of the file could be anywhere in the MVC, if you searched and removed all the whitepace, extra empty line, the error should go away.
What if it still doesn’t work?
The solution is simple, search again! People always miss to search Model, because they focus on controller and view and may assume Model just works. Go and do a thorough search again – Seek, you shall find!
Hope this helps! :)
Make Flash Screensaver for Mac
After trying a few softwares that make Flash Screensavers for Mac, I have come to the conclusion that SCREENTIME V3 is the best. It’s a paid software but with a trial version for tryout. It’s easy to use and provides the flexibility that people can customize the look and feel, installation process and the functionality of the screensaver.
