Let's say, I investigate Lithuania. For example, I have a row containing potatoes production in 1998, 1999, ..., 2009 in Lithuania. I can easily find the maximum value in this row but...

This falls into the category of "wonder if anyone''s done this"? The site I''m working on now has affiliate sponsors who provide link HTML. Almost all of it violates some W3C spec for XHTML, the primary offenders being capitalized tag names and unclosed tags like IMG. They also include ampersands as query-string separators, which also offends the W3C Validator. Has

I've been working with Samba in an AD domain setting for several years now. Small potatoes, nothing fancy. A few months ago, I came across the limitation of Samba, in comparison to file sharing from a Windows server, that, at the current moment, it doesn't offer an indexing service that is compatible with Windows Search. So, no matter how much I like Samba, if I need this feature, I have

Just as an exercise I am tying to add colours to a geom_segment command. I can get one colour but not a sequence of colours. Can anyone suggest how I can get the green lines in the plot below to be different colours? I thought I could use a palatte of colours but that did not seem to work.

Hi, I often find myself using bits of code like this inside ActiveRecord, perhaps it''s useful for others, or others can improve on it: ########### # fix user input before validating it before_validation :sanitize_input # santize input before actual validation is called # this uses the little methods defined below def sanitize_input trim %w(adres postcode woonplaats email naam

Hi, I was wondering if it is possible to share a partial across views in different controllers? If so, how would I go about doing this? Would I pass in a parameter to render(...) of the partial telling it where it is located? And help would be appreciated. -------------- next part -------------- An HTML attachment was scrubbed...

Hi, If you type a keyword and press Enter in the search field on the wiki, it does a title-search by default which is very limited. I tried looking for information about atheros or madwifi and couldn't find anything. Then I tried ipw2200 (I knew it existed because I created it) and no results still. I had to ask Ralph to see if the index was old, only to find out that there is a

I''m trying to get the following idea to work: <%= @column_names.each { |t| <td> t.downcase </td> <td> @listing.send(t.downcase)</td> } %> Essentially I want to display a form that has a left and right TD, with the left TD being a column name and the right TD being the column data. If there''s a better way (the Rails way ?), I''m all ears

The following script creates a search index and then searches it. I get no results? Where am I going wrong? Thanks. -----------BEGIN SCRIPT---------------- require ''rubygems'' require ''ferret'' include Ferret path = ''/tmp/myindex'' field_infos = Ferret::Index::FieldInfos.new() field_infos.add_field(:name, :store => :yes, :index => :yes)

Hello all I am wondering how rails handles case sensitivity in databases. If I do a Person.find_all_by_name("tim") in mysql I would expect to get tim, TIm, and Tim. Do I only get tim in postgres? How do other people deal with this? Do you resort to find_by_sql for all your postgres queries to get case insensitive results?

Hey .. The QueryParser RDoc page explains to me on how to search for a specific value in a specific field. This is not working the way i thought it should be, what am i doing wrong? Here''s an example .. I''m storing model data in the index like this: doc << Field.new( "object_id", object.id, Field::Store::YES) doc << Field.new( "type",

I can consistently segfault the 0.10.4 gem, so I''m trying to get the subversion version working with hopes towards tracking the problem down. I have a fresh SVN checkout but: a) the version (in ferret.rb) claims to be 0.9.6; and b) Ferret::Index::FieldInfos and a couple other classes are missing at run time. It looks like this is because they''re not exported in the C

I am trying to create a simple dot-plot in ggplot2 with a solid line from the y-axis to the dot, something I first saw in Cleveland's 1984 book What I would like is to have the graph start at zero on the x-axis but leave some space on the right side of the plot area. I assumed that I should be able to do this with expand() in scale_x_continuous() but either I'm wrong or just don't

I want to add case_sensitive option to inclusion validation. This will allow to do: validates :numbers, :inclusion => { :in => %(One Two), :case_sensitive => false } Does it make a sense?

Hi ! (See references at the end) I have a slight problem. Whenever I save one of my domain models, which contains an has_and_belongs_to_many relationship with another one, the relationships are doubled. My domain is a series of pictures, where each picture can be tagged with one or more words. So, a picture of my dog could be tagged "Jordy, Dog, Dog 2005", for example. In my
