Re: Production Web Applications in Prolog

Hi Paul

Interesting application.

Since I'm looking for an application domain to showcase what's is going on
in the new console (revamped swipl-win), I could be interested to use some
bit of SWEET, eventually contributing to your project.
Sadly, I was unable to spot the GitHub repository to evaluate what's
available. Do you mind to share the URL, if available ?

Also, I wonder if you could share some hint about running SWI-Prolog on EC2.
This seems really interesting to me, but I'm a total newbie...

I summarily browsed the 'prices' page on Amazon WEB services, but I miss
some fundamental notion.
Did you bought apart the top level domain, or that's included ?
And are you allowed to rebuild SWI-Prolog from sources ? or you're bound to
a distro pkg ?

Thanks for the attention....

bye Carlo
