Hi HN,<p>Handling the scheduled tasks was always a headache for us in our startups. There are problems in calculating months, years, minutes, etc. and on the other hand, the web is not made to handle scheduled tasks. Using programming hacks is not the appropriate method to do scheduled tasks. MySql Cron, Windows Scheduled Tasks and .VB files, uptime checkers, on expired events on caching objects, and thousands of other methods are all hacks. They are not made to do this job, they are very, very limited, unreliable and not easy to implement.
We have not any commercial purpose when we created this service(and yet).<p>We decided to make public this tool for web developers as a freeware:<p>http://atrigger.com/<p>We've made 3 libraries for Ruby, .Net and PHP and other languages can use simple HTTP API.<p>We are curious about your reviews, and your feedback is important to us.<p>Thanks.
