About this Site
The Travel Web site was initially created as a gift for
Dan Walker's 60th
birthday from his family, and will be completed over a period of time,
when time permits.
Technical: Where is Dan
Follow Dan across the globe! Using satellites and a Global Positioning
System (GPS) technologies, Dan is now able to transmit his coordinates
on a daily basis (providing he can find an Internet connection in the
country he is in). Dan uses a GPS to locate his coordinates.
Technical: Photo Album
The Photos seen in the photoalbum were taken using a digital
camera. Custom software was written to archive (ZIP) the photos into a
single file for upload. On the server, custom software extracts the photos
from the archive and adds them to a MySQL database. Through administrative Web
pages, Dan is able to create/modify photo albums and add comments to the
photographs. Most of the server-side software is written in PHP (see below).
Technical: Travel Journals
Throughout his travels, Dan always sends out regular travel journal updates
via email to a custom mailing list (consisting of mostly friends and family).
A program was written using procmail
to receive travel journal updates via email, and automatically add them to
All maps were originally generated in 2001 using the (now defunct) Xerox PARC Map Server. A
program was written to automatically request all of the quadrants from the
map server, download them and chop it up to be
the correct size. The map colourization was a painful manual process.
Map layering was done using HTML CSS-P (Layers).
The entire Website is written using the
PHP Web programing language. Backend
database is MySql. The server is a
RedHat Linux server.
