Show HN: Cron.io - Sharing a by-product. Should this be a full service?

Would creating 60 jobs polling the same URL at 1 min intervals translate to the site getting polled every second? Or is there batching/coalescing of the same-URL jobs?

The crons are spaced out over time.

This is actually why i took so long to launch the site. I've used the prototype version of this for a long time. The app is written in node so it is incredibly fast, like destroy the internet fast. That is why email confirmations are required and accounts are limited to 5 crons each. I will add a captcha on account confirmation shortly as well.

Alternatively you could get the user to validate ownership of a domain, i.e. if you want to run jobs at http://foo.com/something, tell them to create http://foo.com/cronio.txt with specific contents.

Google does something like this: http://support.google.com/a/bin/answer.py?hl=en&answer=6... -- their alternatives also include changing DNS to add a dummy TXT record.

haha I actually like that line a lot. Describes exactly how I feel whenever I'm using node.

Do tell me you are checking robots.txt then. This has a great potential for DoS, email confirmations or not.

This is a prototype service and I am watching the activity closely.

I appreciate your concern.
