This is Warren Kwok's Internet note pad, electronic diary, online rubbish journal, whatever you might name it ! It is an archive of my random thoughts in a chronological order.

I have been looking for a free pdf software to convert documents to pdf format. Adobe Acrobat sold at US$500 per licence is too costly. I finally found dopdf to suit my need.
Every body needs pdf converter. I wonder why it is not included in office suite.
