No Custom Validation
Hi,
Correct me if I am wrong but there doesn''t seem to be an easy way to add
validation outside the pre-built ones (validates_presence_of,
validates_lenght_of, etc.).
Ideally there should be something like:
Class Person < ActiveRecord::Base
validates :my_method, :on => create, :message => ''was not valid''

development and production running simultaneously?
I''d like to be able to run both development and production as follows:
www.mysite.com will be running production
dev.mysite.com will be running development
It should run the same code base. The server is RedHat Enterprise 3,
Apache, FastCgi.
My problem is I don''t know where to set the environment so the
application bootstraps depending on the virtual host (www/dev).

Stability issues since moving to 4.6 - Kernel paging request bug + VM left in null state
Since moving from 4.4 to 4.6, I've been seeing an increasing number of
stability issues on our hypervisors. I'm not clear if there's a singular
root cause here, or if I'm dealing with multiple bugs.
One of the more common ones I've seen, is a VM on shutdown will remain in
the null state and a kernel bug is thrown:

problems with NVS310
I have a Nvidia NVS310 installed in my Linux computer for a few years.
It works well with the Nvidia driver, and not so well with the Linux
nouveau driver. The Nvidia NVS310 has never worked well with Linux. In
the beginning (many years ago) I decided to install Nvidia proprietary
drivers, but every kernel upgrade would require an additional effort to
have the driver working. That was enough
