HTNet - A Notepad of Tech, Business, Science and Self Improvement

I know my posting frequency has been less frequent than normal. The reason for this is that I’ve been packing some stuff at the office. We’re moving. It’s so tiring that the last thing I want to do is to type on a computer.

I’ve upgraded several of my blogs to WordPress 2.5. However, I noticed that two of them didn’t handle 404 (Page Not Found) errors properly after the upgrade.

Yahoo! Pipes is an interactive feed aggregator and manipulation tool. It can combine, filter and sort multiple feed data and spit out a single customized feed that you can use for yourself or share with others.

Before today, JSON has been the only way for you to obtain the output data of a Pipe. Now, Yahoo! has provided a second way to do this: serialized PHP.

I’m sure those who are more proficient with PHP will find this feature very useful. Thanks Yahoo!
