And also what if I put more down payments, what would be my monthly repayment? Will it be much different?

So I decide to write myself a simple program. It is based on fixed rate mortgage. This simple program gives me a brief idea on the monthly repayment I will need to make if I take a loan from bank. Simple key in the total property price, down payment, annual interest rate and terms of loan, then the program will calculate the monthly payment for you.

Your can put the little program at your website too. Simple get the code at Mortgage Payment Calculator.

It is the newer version of my old Default Trackbacks WordPress plugin that I wrote 4 years ago.

The main changes in the new plugin is that now you can save trackback URLs in Worpdress administration page instead of text file and also improvement in prevention of sending double trackbacks to the same URL.

You can download the new plugin here or WordPress Plugin website or alternately download directly from your WordPress admin page by searching the keywords “default trackbacks”.

I have just wrote a WordPress plugin for Blogtal. It is a plugin to send trackback of a newly published post in WordPress to www.blogtal.com. I called the plugin "Blogtal Trackback".

Unlike the older version of my plugin, Default Trackback, Blogtal Trackback will not send trackback to Blogtal when you are saving a published post. You also can configure the trackback settings inside WordPress' admin page.

For those who has registered with Blogtal, using WordPress as their blog platform and still using manual trackback at www.blogtal.com or not sending trackback at all, you can try installing this plugin.

If you have any comment/question about the plugin, please do not hesitate to leave a message here.

The is widget-able theme. I think I will be using this for my blogs in future. If you see a blog with theme similar to this one, it may be my blog :)

Summarily, the theme has the following features:

  • optimized for search engines (hopefully).
  • configurable Adsense codes at a separate PHP files so that you won't need to modify each PHP file everytime you do an update to the Adsense code (e.g. change layout and channel).
  • automated insertion of adsense code in the post. it detects the >!--more< code and replace it with Adsense code
  • widget-able. you are allowed to add any widget to the sidebar from the administrative page
  • a special page for Google Adsense search result

Actually the coding work is pretty simple. I just need to modify the default theme came with WordPress to apply my design. I hope my blog readers will find these theme is more pleasant to read :)

Bloggers can find other people's posts of their interest here too.

This project took me about two months to finsih... from reading specification to writing code. I only do my coding work during my spare time. This site is written fully in PHP, MYSQL as it backend database and no third part's plugin is used.

The site has been tested online for a few days, it might still have bugs. Thanks to blog.enrii and Boredworkers.com as the site's tester.

At first, I was thinking to use the standalone implementation of trackback from movabletype (which is free and wrtten in perl) but it has too little control. Thus, I decided to develop my own implementation from the trackback specifaction.

Here are some of the interesting features of the site:
* Multiple trackbacks per user account.
* Unique trackback url for each blog profile
* Trackback pings are filed under blog profile and a category/interest.
* Own developed trackback interface to reduce duplicated trackback pings and to reduce spams.

This is an ongoing project, so more more features will be integrated... but it will take time :)

If you are interested in sharing your post, you can register an account at Blogtal.com

If you any comments, you can always leave a comment here.

Note: For wordpress user, it is recommended to use auto-trackback instead of my default-trackback to send trackback to blogtal.com

Default Trackbacks automatically insert a set of predefined trackback URLs into "Send trackbacks to:" field when user create a new post or editing an existing post.

Some pinger sites (such as http://www.petalingstreet.org/) use Movabletype's TrackBack URL as the ping URL. This plugin will be useful when user has a list of frequently used trackback URLs as his/her blog's ping URLs.

Features:

  • Automatically insert a set of predefined trackback URLs into "Send trackbacks to:" field.
  • Support simple post and advance post control.
  • Support multiple trackback URLs.
  • No database.

Requirements:

  • WordPress 1.5.x and above

Installation:

  • Download and unzip to a temporary folder. It should only have 2 files: default-trackbacks.php and trackback.txt
  • Use text editor to modify trackback.txt. Type in the trackback URLs that you used frequently, seperated by new line or white space.
  • Upload all the files to your wordpress' plugin directory so that you end up with wp-content/plugins/default-trackbacks/default-trackbacks.php in your blog filesystem.
  • Activate the plugin called 'Default Trackbacks'.

Download:

Historical maintenance:

  • 1.1 - Only load default trackbacks if “Send trackbacks to:? field is empty. To upgrade, simply replace the file default-trackback.php.
  • 1.0 - Original.

F.a.q.

  • Why sometimes it can ping, sometimes it cant?
    Actually there is nothing wrong with the plugin. The plugin only help you to "type" in the predefined trackback urls in to trackback field. It has the same effect as you type in the urls by yourself. All the actual trackback and ping works is done by wordpress. When a trackback is failed, it might be caused by the network problem between your pc and your blog server or your blog server and the target urls or the target url does not response within the HTTP timeout time (server too busy).
