[Howto] custom and translated AR validation error messages
Hi,
I''m putting the finishing touches on a multi-lingual application, and
just posted a blog entry on how I did translate validation errors
generated by ActiveRecord at: http://www.myowndb.com/blog/?p=4
I found it surprisingly easy, and thought I''d document it.
The translation is based on a plugin I plan to publish really really
soon, more info whith the upcoming announcement.

multiple databases
Hi,
I''m writing a translation plugin which takes the translations from a
database that is different than the application''s main database.
When in my plugin''s models I put this code:
ActiveRecord::Base.establish_connection(
RAILS_ENV+"-translations"
)
all my application''s models use the plugin''s database....

io mode=native precisions
Hi,
Before switching to io mode=native, I wanted to check if there are any
disadvantages or potential problem with this setting.
I virtio-blk data plane required to use this setting effectively? (as
illustrated here:

Is there a requirement on the host kernel (eg minimum version)?
Thanks in advance

Voiceblue and slow dialling
Hi,
I have recently started a job as a system administrator, and as part of my responsibilities I have to look after an asterisk system. Quite impressed with it, but have one or two niggling issues. One of the last things my predecessor here did, was install a VoiceBlue mobile gateway unit, and though it seems to work ok, nearl 20 seconds pass from dialling a number to the call connecting, which

plugins problems with RoR 1.1 in production
Hi,
I''m looking to upgrade an application based on rails 1.0, and I have a
problem with plugins working fine in development, but not in
production or test. Actually, it happens in all environments with
their dependency mechanism set to :load.
For example for the selenium on rails plugin, it needs the class
SeleniumOnRailsConfig, which triggers the dependency on

datetime returned as string, sometimes....
Hi,
I''m using postgresql 8.1, rails 1.0, and I have a strange problem on a

sometimes a Time instance, depending of where the value is used....:

detecting blanks in read.table()
Hi everyone,
I am trying to read in a tab delimited data file to R that has outliers
marked by blank spaces. I would like to be able to tag those as "NA"
when the data is read in. I cannot figure out how to do this using the
read.table() options. Everything I have tried either puts all the NA on
the end of the row when there are missing values instead of on their

how to provide plugin configuration?
Hi,
I''m finalising a translation plugin I use in one app. I''d like the
plugin the be configurable but am not sure how to provide this
configurability. For example, there''s a setting for the cookie name to
use when saving user''s prefered language. I thought of having a class
TranslationConfig like this:

adding additional information to histogram
Hi,
I am a beginner with R, and I think the answer to my question will
seem obvious, but after searching and trying without success I've
decided to post to the list.
I am working with data loaded from a csv filewith these fields:
order_id, item_value
As an order can have multiple items, an order_id may be present
multiple times in the CSV.

help formatting data for clustering
Hi,
I'm a R beginner. I have data of this form:
user_id, brand_id1, brand_id2, .....
for example:
1 , 45 , 32, 45, 23
2 , 34
4, 11, 43, 45
I'm looking for the right procedure to be able to cluster users. I am
especially interested to know which functions to use at each step.
I am currently able to load the data in a data frame, each row's name being
the user id.

Myowndb: a web database built with rails
Hi all,
I wanted to announce on this list that I have launched http://myowndb.com which
is a web database built with Ruby on Rails.
The application lets the administrator users define the data structure through
a web interface like in a normal database, with:
- tables
- enhanced datatypes like emaili, web URL, and a choice in list
- relations (one to many, one to one) between tables

host crashes "unable to handle paging request"
Hi,
we have regular crashed of a kvm host with the error "unable to handle
paging request".
Can this be due to memory over-commitment even if some memory is still used
by the kernel for caches and buffers? (collectd graph shows no free
memory, with 15G used, very little buffers, and 1G cache). There are 32GB
of swap, of which only 150MB are used.
