Can we cache user home pages?
Hi Railers,
I am trying to create a simple application like a guest book which has users

Thanks!

I'm trying to calculate the percent change for a time-series variable.
Basically the first several observations often look like this,

the next, I end up with a lot of NA/Nan/INF, and

Messy Cookies
It looks like everyone has tried to fix the cookies lately, and no-one managed
to get it 100% correctly.
The current implementation doesn''t set the path correctly, and you can''t use
@cookies in a #service-overload.
Qwzybug''s patch fixed only the sessions.
Jenna''s patch won''t allow to set complex cookies (@cookies.key = {:path =>

Issue with concatenation of URL losing
a) you need to read the help pages on the paste function... more likely
you are looking for the paste0 function because extra spaces will most
