Hi, I have tried to install the R package Rcplex on windows xp without success. I have only cplex_studio124.win-x86-32 version. I have modified the makevars.win file as indicated in the installation guide ( http://cran.r-project.org/web/packages/Rcplex/INSTALL ), then I zipped the whole folder to order an installation from a zipped file (utils :menuInstallLocal()) The message I had is file

Is it my imagination or has there been a huge increase in the number of fragmented threads in the last several days? Maybe it''s Gmail doing something crazy, but I see dozens of top-level conversations starting with replies (ex. "Re: [Rails] omfg something broke"). Did people collectively forget what the "reply" button looks like, or is the list software doing

Yesterday, I was having a problem with db:migrate. I was told my version of rails was too old, and I needed to install it from gems instead of the version in my version of Ubuntu. Since then, I''ve done that, and I built ruby 1.8.4 from source and installed it. The installation was to /usr/local/bin. As my distribution had put ruby 1.8.3 in /usr/bin, I renamed that and put a link to

Why this code doesn''t work as expected? It raises exceptions everytime. Tried with || operator, too. validates_each :x, :y do |record, attr| record.errors.add (attr, ''between 1 and 100'') if (attr.to_i>100 or attr.to_i<0) end -- They say money can''t buy happiness? Look at the smile on my face... ear to ear, baby!

This is way offtopic, but I''ve seen this several times recently and it''s annoying me. If you put "HOWTO" in your subject that means that you''re posting a guide on a particular topic. It doesn''t mean that you''re asking a question about "how to" do something. It''s not like it''s a crisis, but it screws up searches

I''m using ruby on rails on a Macbook Pro with sqlite3. I''m finding that memory for the ruby process stays about 20mb until I hit an error after which the mermory doesn''t seem to be released and keeps going up until I can''t use my machine. What could be causing this? is it using sqlite3? have I set up rails or ruby wrong? Tim -------------- next part

Do most others in the community agree with this statement? It seems to me that i18n is: 1. Actually important to many people 2. Not really the difficult to implement in concept 3. Something that people like to point out about Rails to say it''s not ready foir "Enterprise" It seems to be that a big part of Rails is encouraging people to do things the "Right Way",

I read in the instructions of Tracks that "upgrading via the rake migrate command is quite a bit more tricky currently with SQLite and SQLite3". Is there any gotcha regarding migrations and SQLite3? -- fxn

Is there any way to tell Rails to send the .html file it renders somewhere other than the web server? I need to save a page to the server''s file system instead of sending it to the user''s browser.

Does anyone have a sense for how painful the 1.0 -> 1.1 upgrade is going to be for existing apps? I''m finishing up my first real RoR application with Rails 1.0. I can live with it staying at that level, but I really want to use the has_many :through attribute to clean up some of my code. I''m not particularly interested in edge Rails, mainly because the documentation for

This might be obvious to everyone but it is something that i haven''t been able to find an answer to. Do I need to have either scgi/fastcgi/cgi running on either lighttpd/apache for ruby scripts to work? If yes, why?

I have a model (Query) which I use to, of all things, query the database. This is to enable raw SQL access. I want to ensure that db access using this model is read-only. Short of checking the sql query for ''insert'' and ''drop'' and ''update'', is there a more rails-like way of doing this in my app/models/query.rb itself? Thanks in advance,

The Pragmatic Programmers guide to Rails says, temptingly: "After filters can be used to modify the outbound response, changing the headers and content if required. Some applications use this technique to perform global replacements in the content generated by the controller?s templates (for
