If you wish to get ObjectAda, please register at aonix.com

I have mirrored it @ http://backstab.org.uk/~limbo/full_722.zip (hosted in myloca)

www.w3schools.com for abit more "advanced" tutorials on web-based stuff like HTML, ASP, PHP etc.

There is also a try-it editor where you can just edit code in your browser and make it run on the same page. However it doesn't teach on all the functions (although it does list them), it also lacks a parametere list for the functions. Overall its a good 2nd reference IMHO.

-update-
http://sqlcourse.com for quick sql courses for newbies.
