Hello, I need help with something. I just downloaded the OSX binary
for web2py, copied it to my Applications folder, launched it, entered
a password, started the server, then tried to log into the
administrative interface, but everytime I enter my password, it just
keeps reloading the log in page.
This new cheat sheet is great! I saw the one page version, but I agree
there is too much information to fit on to one page. I'm glad a second page
was added.

I don't know about that. I've started installing Concrete5 for people

I don't think you are supposed to open more than one connection to a SQLite

abilities like other databases like MySQL and PostgreSQL.

I don't think you can because "current" is a threaded object. It contains 3
things: request, response, session. You could probably serialize much of
the data contained in those three objects, however, this will be difficult

Hope that helps.
There's a sticky on this somewhere, but webfaction is always recommended.
There is also Google App Engine. If you would like a VPS-like host instead,
then Rackspace, VPS.NET and Amazon EC2 are also options.
HamlPy is actually really cool. I've never heard or seen anything about it

You just have to design them properly or the plugins will rely on each

the auth tables are there by default. But plugins are meant to be

exist.
