Hi guys, As we discussed in the last CentOS SIG Virt meeting below the steps that we do to rebuild the qemu-kvm from http://vault.centos.org to enable the rhev-features like live snapshot for CentOS. 1. Download the last qemu-kvm from http://vault.centos.org/${version}/updates/Source/SPackages/ 2. mock -D "${build_version}" -r epel-6-x86_64 --with=rhev-features --rebuild

Add man/mkfs.btrfs.8.in Kept the name with the name in, so that further processing such as BUILD_DATE BUILD_VERSION etc. could be included later. All man pages included in the man directory to avoid file cluttering.

Greetings all. I''m using the Microsoft "NorthWind Traders" database "orders" table as test data for the Rico LiveGrid JavaScript. The problem I''m noticing is that some of the records in the "ShipName" field contain ampersands -- which for some reason are not being escaped by Rails. Rails does in fact automatically escape all of the other

Hi Gabor, I just used your R code below and the code worked properly without any error messages. Attached is the output graph, which may be the one you expected. library("Rgraphviz") set.seed(123) V <- letters[1:10] M <- 1:4 g1 <- randomGraph(V, M, 0.2) g1 plot(g1) Thanks.

Let''s say you want to validate that an attribute contains only 2-10 lowercase characters, e.g. with validates_format_of. The appropriate regex is obviously /^[a-z]{2,10}$/, right? Wrong! Try it with "abc\nANYTHING YOU LIKE" - this is perfectly valid. On the second look the reason is clear: ^ matches the start of a line, $ matches the end of a line. So as long as one line in

I am having problems with this: validates_presence_of :amount validates_format_of :amount, :with => Money::PATTERN, :allow_nil => true composed_of :amount, :class_name => Money, :mapping => [[:amount, :to_s]] The problem is when I use this field in a form, and the text is blank, ActiveRecord gives me two errors: "money is invalid" "money

Hi, How can I validate user info under certain conditions? For example, I just downloaded a plug-in that allows me to validate phone numbers, but what I would like is to only validate the phone number if it is not blank and if the user_type_id field is equal to one. How can I achieve such a validation in my user model? Thanks, - Dave --~--~---------~--~----~------------~-------~--~----~ You

Hello all, As the subject states, I have a 3Com 3c940 Ethernet card to a 1 gb network switch. The switch detects it, but it only shows that it is giving me 100 mb/sec throughput.

I am getting a handful of these errors, and I am not sure why. The directories in question have rights like this: drw-r--r-- 2 osstbb osstbb 42 2008-05-02 00:04 12981826/ As root, why would it matter if it has executability? I can read it just fine on the server. Or is it an issue when it tries to create it on the -client- ? Is there a way to fix this? I can chmod 0755 the dirs on the server

It seems to be rather repetitive. validates_format_of :expiration_date, :with => /^[0-9]{4}[-][0-9]{2}[-][0-9]{2}$/ validates_format_of :activation_date, :with => /^[0-9]{4}[-][0-9]{2}[-][0-9]{2}$/ validates_format_of :some_other_date, :with =>

ActiveRecord supports composed_of for value objects which is fantastic but one thing that it doesn''t seem to support (or at least I am unable to find any documentation for) validation of the value objects. For example, given the following: class Message < ActiveRecord::Base composed_of :sender, :class_name => ''EmailAddress'' composed_of :recipient,

I''m working on upgrading to rails 1.2.2 from 1.1.6 and getting the mongrel error below in development mode. Now things seem to work fine with 1.1.6and 1.2.2 (in prod mode).
