similar to: Apache 2.2 + Mod Proxy Balancer + Mongrel - Hot Linking Protection?

Howdy, I''m using Apache 2.2 + Mongrel with great success, using the sample configs from the Mongrel site. We have some MP3s on the site and recently someone has been stealing them and basically leaching them from the site, linking to them from an off-site location. I''ve been trying to modify my Apache conf to check the referrer and adjust accordingly as below but no

In production mode, I keep getting this error the 2nd time it loads a page with a serialized attribute: ActiveRecord::SerializationTypeMismatch (answers_container was supposed to be a Array, but was a NilClass): /vendor/rails/activerecord/lib/active_record/base.rb:1964:in `unserialize_attribute'' In development, it works fine. In fact, if I set to false config.cache_classes in

Dear R-user, I am trying to use the function 'parLapply' from the 'snow' package which is supposed to work the same wys as 'lapply' but for a parallelized cluster of computers. The function I am trying to call in parallel is 'dudi.pca' (from the 'ade4' package) which performs principal component analyses. When I call this function on a list of

Hi Everyone, I'm trying to use cutree to get the clusters after hclust. What I used is: mycluster<-cutree(cnclust,h=0.5) Now, my problem is, how can I get the actual clusters? Thanks! Best, Baoqiang Cao

Hello all; I'm trying to execute parallel jobs trough library snow on a cluster built through torque/PSB. I'm succesfully obtaining the cluster with: >system("cat $PBS_NODEFILE > cluster.txt") >mycluster <- scan(file="cluster.txt",what="character") >cl <- makeSOCKcluster(mycluster) The only problem, at the moment, is that if I use

Hello I have a rails 3 app and I am trying to implement the redirect back action at access denied for cancan. If I try this in my application_controller: rescue_from CanCan::AccessDenied do |exception| redirect_to :back end It gives the following error: No HTTP_REFERER was set in the request to this action, so redirect_to :back could not be called successfully. If this is a test, make sure

Hi,All.Sorry for the group mail. I recently met a question and I have struggled on that for a while but failed to found the solution. I have a distance matrix as below. --- 0 35 33 9 36 35 0 10 32 51 33 10 0 30 49 9 32 30 0 35 36 51 49 35 0 ------------------- I want to do cluster with average method. ---- rown<-c("A",

Hi. I would like to set @request.env["HTTP_REFERER"] in an integration test, but due to its nature, I would naturally set this value to the previousle request url. How do I do that. Thanks. Jarl

Alright, it seems that I am having a bit of a problem with mongrel. My mongrel processes have been crashing pretty often and twice last night. I''m really not sure why, but I really need to fix it. I am running 0.3.13.3. Here is the mongrel.log file. Any ideas, things to look at, etc... is appreciated. Thanks, Carl PS, do all the broken pipe lines mean Mongrel is serving the static

Hello, we want to read the referer URL from the HTTP headers, in order to be able to track where someone is coming from, in a Rails application. As I can see in the source, Mongrel doesn''t even parse the HTTP_REFERER field from HTTP requests. This would make a useful feature, I guess. Apart from that, Mongrel is (IMHO) simply the best solution for deploying Rails - keep on going!

Hello! I created a distances matrix for 13 objects using daisy (see the attached file). I am trying to clusteranalyse it using agnes but it's not working. What might be the problem: mydistances<-read.csv("Results of daisy.csv") mycluster<-agnes(mydistances, method="ward") I am getting: Error in agnes(mydistances, method = "ward") : NA/NaN/Inf in foreign

I''ve got my application running under Windows with mongrel perfectly, so it was time to convert it to a service. service::install works fine, but service:start gives me some "One moment, start pending" and then lots of "One moment, stopped". After a bit of digging I found this in the service.log: ** Starting Mongrel in production mode at :3000 ** Starting Rails in

Whilst monitoring my host I noticed that there were three mongrel_rails processes running for a single (non mongrel_clustered) application. Is this normal? Do the processes share the memory top indicates they''re each using? Cheers, -- Dave Murphy (Schwuk) http://schwuk.com

Any news on the Apache Best Practice Deployment instructions? I''m getting ready to set up a production server, and would prefer to use Apache and Mongrel/Cluster. Don''t think I''ll be able to get the latest Apache though. Do I have to proxy through Pound or something to handle multiple mongrel instances? Any pointers? Any help appreciated, Brett

I''m getting the following error. Which apt-get install <some missing package> do I need to run? looks like some build tools. Building native extensions. This could take a while... extconf.rb:1:in `require'': no such file to load -- mkmf (LoadError) from extconf.rb:1 ERROR: While executing gem ...

Hi James, > Isn't this from the query template, ie from the main web page of search > results? (It might make sense from opensearch as well, though.) Yes, you are right; it is the query template. The reason I said opensearch template is that I haven't quite read all sections of the Omega docs and I'm still in the process. Thanks for pointing that out. I'm aiming to cover

Hi, I''m trying to create a chatboard (I call it my BoomBox, each post is called a "boom") which appears on every page of a weblog I''m building. I have a scaffold-built controller called Boom, and the form to post to the BoomBox is written into my default layout. So, the form can be viewed from several of my other controllers, in most of their actions. The form

Hey, Is is possible to get the full URL (''http://www.sender-domain.com/links/list.html'') from where a user was sent to my site (www.my-domain.com/controller/action) e.g. by clicking on a link? (I read about something called a ''request'' object, I don''t know what it is or does, is that what I''m looking for? I''m very new to Rails

So, I want to build the greatest online radio ever! (for my, currently crappy, faderwave.net radio station. Right now, I''m running Icecast straight up. The only problem is that managing different DJs and keeping them off the air when they aren''t supposed to be there is a pain. There also is not one single management package that does everything. My current system is a hacked

I''ve been mulling over an idea for a book covering Ruby on Rails application deployment. Obvious topics include using Mongrel by itself and with Apache/Lighttpd, load balancers, memcached, and Capistrano. What other topics would you like to see covered in such a book?
