search for: tributaries

Hello, I'm modeling a watershed, and have a file linking individual tributaries - the name of each tributary and the water body into which it flows (which can be a tributary of another water body). I want to use this to build a tree data structure (a root, and then child nodes, linked to further child nodes, etc.). Is there a package that builds and traverses such data struc...

Hi All, I am modifying typo so as, I can host multiple blogs on the same typo. And its almost done, except that...i am stuck at one place. When a user posts a new article, depending upon current blog_id, I would like to set the blog_id attribute of @article object. So..in the admin/content_controller.rb: We have: def new_or_edit if request.post? set_article_author

Hi Ezra/skaar, Wow man, the exercise was worth it. The connection closed problem with socket as i mentioned in my earlier mails...completely disappeared, and now i can connect only once to the socket and keep reading..till end of its days. Literally impossible with older release of backgroundrb. This could also potentially solve the issues people were having with ActiveRecord. As i said

Ok, here is the class, I want to Unit Test, its part of a large app and is based on EventMachine library. I want to mock the class TickServer ( i.e not stub it) . Since in actual scenario, you can''t do this on this class: @server = TickServer.new # will toss an exception at your face you must initialize the server like this: EventMachine.run {

I have installed mongrel and mongrel_cluster fine and have them running great with my app. I tried using the init.d script provided with mongrel_cluster 2.1 to start it up on boot but it doesn''t. mongrel_cluster_ctl works fine for me by hand and so does /etc/init.d./mongrel_cluster start. I am on Debian so I installed the service links with sudo update-rc.d mongrel_cluster defaults. And

Hi dear R-listers, I'm trying to fit a 3-level model using lme in R. My sample size is about 2965 and 3 factors: year (5 levels), ssize (4 levels), condition (2 levels). When I issue the following command: > lme(var~year*ssize*condition,random=~ssize+condition|subject,data=smp,method ="ML") I got the following error: Error in logLik.lmeStructInt(lmeSt, lmePars) :

I''m setting up a Rails app for a client that uses Windows.

I am sure..again I am missing something, but I am trying to start a worker, when backgroundrb starts and it doesn''t seem to work. Here is my config/backgroundrb_schedules.yml file: feed_worker: class: feed_worker job_key: feed_worker_key worker_method: do_work trigger_args: repeat_interval: 20.minutes I even tried this from Rails controller: # def start_feed_worker #

In my app, for three models: foo,bar and baz, the database connection is made to a different database and hence in model code: class Foo < ActiveRecord::Base establish_connection :diff_database end class Bar < ActiveRecord::Base establish_connection :diff_database end class Baz < ActiveRecord::Base establish_connection :diff_database end Now, the problem is, if is use the above

When trying to run Chris samples I get error: /usr/lib/ruby/gems/1.8/gems/mocha-0.3.2/lib/smart_test_case.rb:3: uninitialized constant Test (NameError) from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in `require'' from /usr/lib/ruby/gems/1.8/gems/mocha-0.3.2/lib/mocha.rb:1 from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:33:in

This has been asked before, never well attended perhaps. Any thoughts on testing your workers? Current implementation is broken. An empty test case like this: require File.dirname(__FILE__) + ''/../test_helper'' require "#{RAILS_ROOT}/lib/workers/market_summary_worker" require "#{RAILS_ROOT}/vendor/plugins/backgroundrb/lib/backgroundrb.rb" require

I''m very interested in using backgroundrb for running jobs every n minutes. The release notes say that this functionality is not yet ready via backgroundrb. But I wonder, can I call backgroundrb with a ruby script from cron ? I know I could create a cron job that calls lynx (or whatever) on a specific page that will call backgroundrb, but I want to know if there other

People are still using cron jobs for killing one shot workers. I mean...workers, which they want to run only once. I guess putting a "exit 0" at the end of do_work is a better solution. I use it and works great. -- There was only one Road; that it was like a great river: its springs were at every doorstep, and every path was its tributary.

Hi, I have been using Backgroundrb for quite sometime...and now...as i guess its a known problem that...worker threads throw up..."Mysql Connection has Gone away" error..when they run for really long time. Is there any conclusive workaround or solution. If not..and let''s say...my worker threads are not critically important for my app....then which program you guys are using

I''m getting an error I don''t understand when I try to install the BackgrounDRb plugin. I installed the plugin yesterday, or thought I did, and tried this morning to start the daemon. Got an error and so tried to reinstall using: >ruby script\plugin install svn://rubyforge.org//var/svn/backgroundrb --force The first line of the reponse says: svn:

Hey Ezra, I asked this on ruby-talk, but probably you missed it. I am already using Backgroundrb for several other stuff. But i am curious, that how it will work with rubyinline? Ruby threads, should handle it alright..theoretically(since backgroundrb uses ruby threads) But, i would just ask opinions of Ezra on this. Because i feel, stuff at my end needs some real optimization. These worker

Ezra et al: I have this problem: http://rubyforge.org/pipermail/backgroundrb-devel/2006-December/000578.html Any progress on it? Or are unit tests simply impossible for now? -- Phlip http://c2.com/cgi/wiki?ZeekLand <-- NOT a blog!!
