I haven't tried this yet, but I wanted to say I think there's a lot of potential in this space. There's so much friction with the current popular solutions...and yet it's so hard to justify trying some of the newer and less popular ones.
I wish you luck because there are a lot of good ideas in here. Running locally and remote debugger are the most exciting to me.
I'd argue that Tenerife was due to taking off (in bad weather), not landing. But of course, a bunch of planes landing at the same airport without ATC sounds quite dangerous.
This sounds like a very nice compromise actually. I'm surprised it helped with abuse though, since there's a lot of email providers that are easier to create an account with than gmail.
Well, you have to go out of your way to prevent it. The sub-addressing complexity is on the email provider side; ticketmaster doesn't have to do anything for it to work except not reject valid email addresses.
In my experience, most but not all sites will accept "+" email addresses.
I think that's exactly correct. You either do split queries (with more latency) or you do a join (and risk Cartesian explosion). Most ORMs should do this for you.
