It's because they have to provision an Elastic Load Balancer to sit in front of your app. That's the only way they can acquire additional IP addresses from AWS.
They make no money on this arrangement, they are simply passing the ELB costs on to you.
Domains that resolve to an IP... I'm not 100% sure how they are configured behind the scenes, but the ELBs have a bunch of physical IPs wired into them, so they can SSL terminate for many domains, something that EC2 instances cannot (currently) do.
So Heroku leverages the ELBs to circumvent the 1 IP address per EC2 instance issue.
Unless you use SNI (which is only supported in some browsers) you have to have one IP per SSL host as the certificate is sent before decoding the request. ELB doesn't use that and must have 1 IP per hostname.
I didn't know about the solution you mention at the time I wrote the post. I'm reading up on it now and I think it's actually going to end up being the official solution so it's a good flag:
Ha, I know.. I couldn't tell if it is "Pompeii" or "Pompeii of the Permian period". I hate that professional articles have so many typos in them these days.
This sounds like it has potential, although I can't test it yet. You should try searching Google for information on COM programming. Try finding information on "COM Events", for example. Good luck. Macy's is on the the first page! Bing is not any better.
I get "Understanding COM Event Handling" at #1, but agree that it's not ideal. Some words like COM or IT have dual meanings where sometimes you want to treat them like stopwords and sometimes you don't.
Just tried it with verbatim but results are still no good =( I can see how it is doing exactly what it is told to do ("www.yelp.com/events"), but not what I would like. I like the idea of being able to do verbatim searches though! (and still miss the + button...)
I wrote this game as a fun project to learn javascript and jQuery, and to work on my web design skills a bit. Let me know what you think and if it is any fun! :)
Visual Studio may not be the choice environment for many HN'ers, but if you are stuck using it I made free extension to make #regions in Visual Studio less noticeable and work a bit better.
You should have two options, one to use my account, one to use a sample account. People would probably view the sample first, and then if they were interested then they might sign in themselves.
