ActionController::InvalidAuthenticityToken?
Hi-
I am trying to use AJAX calls to login and logout of my Rails app so
that the form renders in the side bar when you are not logged in, and
your "profile" renders if you are.
It all works, but when you logout, and try and log back in, you get
"ActionController::InvalidAuthenticityToken", in the development.log.
What does this mean, I can''t figure out how to fix

datetime_select and Active Record
If I have a form similar to the one below, and ''start'' is a "string"
field in my Database. Is there a way to take all of the date/time
params and put them into ''start'' without too much hacking? I would
like this to be as clean as possible.

will_paginate question
Hi-
Is it possible to use search parameters with will_paginate?
For example, something like this:
@var = Model.paginate :per_page => 20, :page => params[:page],
:order => ''my_date DESC'', :conditions
=>["my_date >= ? AND my_date <=?",@start,@end]
I am getting some errors with this, but will this generally work?

Sort logfiles on common lines?
I have a huge mysql.log file full of errors. I'd like to sort it by
the most common line, and work from there. I did go through the
manpage for sort, and googled a bit, but I found nothing relevant.
Here is an example of the output:
[root@ log]# tail mysqld.log

How to make big MySQL database more diffable/rsyncable? (aka rsyncing big files)
Hello group,
I'm having a very hard time rsyncing efficiently a MySQL database which
contains very large binary blobs.
(Actually, it's the database of Mantis bug tracker
[http://www.mantisbt.org/], with file attachments stored directly in the
table rows. I know it's a bad idea from many other reasons, but let's
say it was given to me as such.)

MySQL index question
I am trying to speed up some DB operations and perhaps have gone overboard
with indexes. Does MySQL usually use only one index per query and simply
match keys on the results of the indexed first part? For example:
DELETE FROM tokens WHERE 6813946236211560448 <= fnv AND fnv < 6818449835838930944 AND updated_at<''2010-06-20 14:08:55'' AND occurrences=0;

Existence of non-vectorised functions
Dear R-Group:
Recently, I ran into a problem. I was using a function called "I.1",
which evaluates the first-order modified Bessel function of the first
kind, in the package "CircStats". This function is not vectorized,
since it uses a couple of "if" conditions. However, when I called this
function with a vector argument, I got no error/warning messages in

I am running into problems with MySQL and lookups. The table has character

send_file - PDF
Hi-
I''d like to load a PDF file into a page, in my controller:
send_file "/path to/my.pdf", :disposition => "inline"
However, instead of rendering inline, it asks to download the file.
How can I display the contents without downloading?
Thanks!
