About ten years ago, I built a WAP (Wireless Application Protocol) mobile news site. This was at a time when the cellphone to aspire for was the Nokia 7110, a slider phone made even cooler when a similar device was used in the Matrix movie.
At that time, the Sun.Star website signed a content agreement with Smart for SMS and WAP news and they needed a WAP mobile site. Nobody among the website staff then knew how to build a WAP site. Being a sucker for always trying to learn new stuff, I volunteered to build it.
I finished the WAP site in time for the launch after a 3-day development marathon done after I finished my work at the Sun.Star Cebu copy desk, fueled by more than a pack of Marlboro reds a day (I was still a heavy smoker then) and guided by a phonebook-thick Wireless Markup Language (WML) reference for the Artus Netgate.
