claps awesome

Genius idea! If only UrbanSpoon was programmed to be completely botproof... :P

cheers :)

Do you have similar code for OpenTable?

@sarah try this gem: https://github.com/dchapman1988/hungrytable

how often did you run this?

I started out by doing it once a minute. That seemed enough to get reservations initially (it was a once a minute crontab).

The new bot that I'm developing does checks every 5 seconds.

genius

Great! It would be interesting powershell script or .NET :-)

So how does this work? Is a cron job constantly running in the background? Is this running locally or on a server?

Genius.

I love this. Did something similar in Python for registering for high-demand classes in college. This is a great time to be a programmer.

Can someone tell me how to use this? Also does it work on ticketmaster as i might try to get some tickets for minecon. Also should i make 1 bot on a computer and one on the other to buy tickets for 2 people such as me and my friend? Help.

Does anyone have a similar script for Resy?

Anyone have a script for Tock or Sevenrooms?
