Dear Group members I was wondering whether there is any interface to use processing (www.processing.org) to visualize R analyses? If so could somebody point me to relevant ressources? If not, are there any attempts to build such an interface / package?

Hi list, ? I am currently trying to configure dovecot to act as a imap proxy in front of a Groupwise server. Because of a policy no services of the gw server may be directly served to the web. So currently this is only a security measure. Dovecot was previously used for providing sasl-auth capabilities to postfix. IMAP proxy features should be added now. Authentication backend is LDAP. OS is

Dear List Members I used to play around with R to answer the following question by simulation (I am aware there is an easy explicit solution, but this is intended to serve as instructional example). Suppose you have a poker game with 6 players and a deck of 52 cards. Compute the empirical frequencies of having a single-suit hand. The way I want the result structured is a boolean nosimulation

I''m a belgian Rails user (Dutch is my native language). I wondered if it is possible to translate error messages (generated by validators). I know how to create my own error messages: def method content rescue logger.error(...) flash[:notice] = ''My own error message" redirect_to(...) But where can I find the validator''s .rb files, so I can change them?

I tried infinite of combinations of mar and cex but nothing helps.

Hello list, I am struggling with setting up dovecot 2.1.7 with samba 4.1.2 on debian wheezy. Dovecot should authenticate via LDAP, but I?cannot get it to work reliably. Sometimes auth works, sometimes not. Referals are already activated in ldap.conf ? LDAP-authentication works fine with other clients (Apache Directory Studio, ?)? Has somebody got a similar setup running? I would love some hints

I''m trying to follow along with the Agile Development with Ruby on Rails book and have encountered a problem with code having the following syntax (partial class provided): require "digest/sha1" class User < ActiveRecord::Base private def self.hash_password(password) Digest:SHA1.hexdigest(password) end end I''m getting an error as: undefined method

I''d like to be able to take a URL and add or modify a param, just like url_for does in ActionController. However, I''d like to be able to do this for a URL taken as a string, without a controller behind it. So I can''t just call url_for. Any ideas? What''s the best way to do this? -- Posted via http://www.ruby-forum.com/.

I would like to build a form which uses ajax on the first request, but on a subsequent request uses the regular form_tag. The reason for doing this is that I need a file upload in the second request, and so I can''t use AJAX. I''ve tried using an rjs template to modify the form_remote_tag''s id (using page.replace ''form_tag_id'', ...), but the request

Hi, I''ve implemented a log in session "thing" that essentially works by holding the model of the logged in user in a session variable, like this: session[:user] = user However let''s say at this point in time, should an administrator of the system decide to revoke this user''s account, the session variable for that currently logged in user is still valid,

I''ve made the following changes to scaffolding.rb. Is it possible to put those changes into some type of a plugin or helper or something, instead of directly modifying the Rails source? (and, btw, I think pagination should be removed from scaffolding. And deletes should only happen on post requests. That''s essentially what I''ve changed). Thanks, Joe Index:

People, For my little book library db I find the rails script generated stuff fine for most of my needs but there is one thing I couldn''t figure out . . Part of the auto output of app/view/books/edit.rhtml is: <%= start_form_tag :action => ''update'', :id => @book %> <%= render :partial => ''form'' %> <%= submit_tag

Hi, I''d like to upcase a variable before it is saved, but I''m not sure how to access the incoming param or where this work should be performed: In my update method, I have: @device = Device.find(params[:id]) params[:device[macaddress]].upcase <-- problem code if @device.update_attributes(params[:device]) ....usual stuff here ''macaddress'' is the

Hello all, I''m using the sanitize() method from TextHelper in my application, which appears to use the VERBOTEN_TAGS constant to define which tags to escape out from the HTML. I''d like to modify VERBOTEN_TAGS to include some more tags, but I''m not sure where I would place the necessary code in my rails app. Any ideas? Thanks, Kamil -- Posted via

Hi Mark, This is the fix for 2.6.29(introduced by uniting the bucket journal access). Since I found no fixes-for-2.6.29 in your ocfs2.git, it is based on your original upstream-linus. In ocfs2_xattr_value_truncate, we may call b-tree codes which will extend the journal transaction. It has a potential problem that it may let the already-accessed-but-not-dirtied buffers gone. So we'd better
