Hi all, I am running on Windows XP sp2 with ruby 1.8.6, and rails 1.2.3 I am using REST, and have this in my view <% form_for(:project, :url => project_path(:user_id => @project.my_user, :id => @project), :html => {:method => :put}) do |f| %> The browser correctly gives <form method="post" action="/users/2/projects/1">

I got a case that I haven't been able to resolve. I hope somebody can give me some hints. One of our users is reporting emails disappearing in front of his eyes, (Right ... emails filters at the client side ....) Server does not have global sieve filter enabled (no file present), even though this configuration is present: sieve_global_path=/vmail/globalsieverc User does not have

My completely empty model (no validation callbacks etc etc) takes an average of 0.05 seconds to create, at least according to Benchmark.realtime{200.times{Message.create(:from => "me@here.com", :message_type => ''email'', :subject => "hello", :body => "goodbye", :sent_at => Time.now)}}/200 That''s a little slower than

In my last post I was asking how I could check for the existance of a record before inserting a new one and this was the helper method that I was using to do this: def already_friend_of?(friend) begin self.friends.find(friend.id) true rescue false end end I was told that this is not very efficient, as it hits the db every time I call it. I completely agree and would like to

Hello List. I am using rsync to pull html files from a shared drive to 2 web server boxes to keep the files synchronized. However, I have a few files I do not want rsync to copy over because they contain information specific (IP address) to the box hosting them. Rsync seems to intermittently ignore the exclude statement and copies them from time to time. Is there a way to absolutely prevent

When I''m executing cucumber tests, I noticed that sometimes rails app (in test env.) getting several the same requests (GET or POST) usually around 3, and it doesn''t render anything with empty HTTP status code. Have anyone met something similar to that issue? here is some example of log file: Started POST "/account" for 127.0.0.1 at 2010-11-30 22:34:17 +0200

Further cleanup of the vmbus driver: 1) Cleanup the interrupt handler by inlining some code. 2) Ensure message handling is performed on the same CPU that takes the vmbus interrupt. 3) Check for events before messages (from the host). 4) Disable auto eoi for the vmbus interrupt since Linux will eoi the interrupt anyway. 5) Some general cleanup. Regards, K. Y

Hey guys, I'm trying to echo my password into some commands inside of a bash script. But I think I'm going about it incorrectly.

Hi, I'm currently trying to setup remote backups of my emails but i'm running into issues (mdbox format, indexes and storage in the same folder hierarchy). Local backup command: dsync -u "my_user" backup /backups/my_user (1) Recently, I noticed that the local backup takes up twice the size as the original mail location (8gb vs. 4gb). I purged alot of emails from the original

Hello, I'm trying to setup a mailserver running postfix and dovecot with mysql as database backend. Postfix is already running and delivers mails just fine. Unfortunately, dovecot has great problems connecting to the database (using username + password). If I disable the password, everthing works fine. But, thats harakiri, security wise ;-) I tried dovecot-1.0-stable and the latest

Running across some curious stuff with ulimit on CentOS 5.10. We have a non CentOS packaged version of Asterisk (using their packages) that we start at boot time with a typical RC script. Recently it started whining that it couldn't open enough file handles. As we dug further into this, it appears that at boot time, it inherits ulimit from init, which is pretty low: 1024. We've set

I installed samba 3.0015. I have a problem when I try to browse my machine from a windows client. In effect I am not able to "open" my unix-client. I checked nmbd and smbd and they are running. If I try from my unix-clinet: smbclient -L my_user -W my_domain -L my_PDC I can see shares. If I try from my unix client: smbclient -L my_user -W my_domain -L my_unix_client I get session setup

Dear all, I am trying to avoid a for loop here and wonder if the following is possible: I have a data.frame with 6 columns and i want to get a cross-correlogram (by using ccf) . Obivously ccf only accepts two columns at once and then returms a list. In fact, with a for loop i?d do the following for (i in 1:6) { x[[i]]=ccf(mydf[,i],mydf[,6]) } Is there any chance to the same with
