  • can I change my open ID URL change?

    - by dhruvbird
    I wanted to know if I can change my open ID url from say: www.abc.com/username to www.pqr.com/username while the relying party still thinks I am the same user? or even say: www.abc.com/something/username to www.abc.com/somethingelse/username I intuitively think that this is not possible since if it were, then it is possible for anyone to spoof anyone else's identity. Also, does Open ID specify which fields the relying party should use to ensure secure determination of the user's identity? For example, I would expect it to club the URL provided with the username/email address sent back by the Open ID server.

  • gem2rpm includes all dependencies instead of including only runtime dependencies

    - by prunio
    Version 0.6.0 of gem2rpm includes all (development and runtime) dependencies for a given Gem. Example: Rack Gem (http://rubygems.org/gems/rack) Version 1.1.0 has no runtime dependencies, but six development dependencies. Console output of gem2rpm --dependencies rack-1.0.1.gem is: rubygem(test-spec) = 0 rubygem(camping) = 0 rubygem(fcgi) = 0 rubygem(memcache-client) = 0 rubygem(mongrel) = 0 rubygem(ruby-openid) = 2.0.0 rubygem(thin) = 0` How can I specify to only include runtime dependencies? I have also opened a ticket on rubyforge.org, but there isn't a lot of activity on that tracker. Thank you for any hints.

  • Newbie, deciding Python or Erlang

    - by Joe
    Hi Guys, I'm a Administrator (unix, Linux and some windows apps such as Exchange) by experience and have never worked on any programming language besides C# and scripting on Bash and lately on powershell. I'm starting out as a service provider and using multiple network/server monitoring tools based on open source (nagios, opennms etc) in order to monitor them. At this moment, being inspired by a design that I came up with, to do more than what is available with the open source at this time, I would like to start programming and test some of these ideas. The requirement is that a server software that captures a stream of data and store them in a database(CouchDB or MongoDB preferably) and the client side (agent installed on a server) would be sending this stream of data on a schedule of every 10 minutes or so. For these two core ideas, I have been reading about Python and Erlang besides ruby. I do plan to use either Amazon or Rackspace where the server platform would run. This gives me the scalability needed when we have more customers with many servers. For that reason alone, I thought Erlang was a better fit(I could be totally wrong, new to this game) and I understand that Erlang has limited support in some ways compared to Ruby or Python. But also I'm totally new to the programming realm of things and any advise would be appreciated grately. Jo

  • Nested Routes and Parameters for Rails URLs (Best Practice)

    - by viatropos
    Hey there, I have a decent understanding of RESTful urls and all the theory behind not nesting urls, but I'm still not quite sure how this looks in an enterprise application, like something like Amazon, StackOverflow, or Google... Google has urls like this: http://code.google.com/apis/ajax/ http://code.google.com/apis/maps/documentation/staticmaps/ https://www.google.com/calendar/render?tab=mc Amazon like this: http://www.amazon.com/books-used-books-textbooks/b/ref=sa_menu_bo0?ie=UTF8&node=283155&pf_rd_p=328655101&pf_rd_s=left-nav-1&pf_rd_t=101&pf_rd_i=507846&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1PK4ZKN4YWJJ9B86ANC9 http://www.amazon.com/Ruby-Programming-Language-David-Flanagan/dp/0596516177/ref=sr_1_1?ie=UTF8&s=books&qid=1258755625&sr=1-1 And StackOverflow like this: http://stackoverflow.com/users/169992/viatropos http://stackoverflow.com/questions/tagged/html http://stackoverflow.com/questions/tagged?tagnames=html&sort=newest&pagesize=15 So my question is, what is best practice in terms of creating urls for systems like these? When do you start storing parameters in the url, when don't you? These big companies don't seem to be following the rules so hotly debated in the ruby community (that you should almost never nest URLs for example), so I'm wondering how you go about implementing your own urls in larger scale projects because it seems like the idea of not nesting urls breaks down at anything larger than a blog. Any tips?

  • Cannot login to Activeadmin after gem update

  • RubyGems installation errors both when using 'sudo' and not using sudo

    - by Kenny Peng
    I have a machine that is running Ubuntu Hardy, which provides its own RubyGems package. Unfortunately that version of RubyGems (1.1.1) is too old to do anything useful with, so I decided to manually update RubyGems to the current version (1.3.6). That part went smoothly, and if I do gem -v, I get 1.3.6 which is expected. The problem is when I try to do: sudo gem install rack, it returns this error: ERROR: While executing gem ... (Errno::EACCES) Permission denied - /home/username/.gem Usually when I install gems as root, it knows to install it into /usr/lib/ruby/gems, so why is it checking my home directory at all? Another quirk is when I do gem install rack (not as root), it says: ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions into the /usr/lib/ruby/gems/1.8 directory. which is where I want it to go. I've already tried clearing source_caches, trying different versions of RubyGems (1.3.5), forcing installation into /usr/lib with -i to no avail. Any ideas on why RubyGems is so insistent on checking my /home directory when installing as root?

  • Rails apps blew up on mediatemple's (dv) server

    - by BandsOnABudget
    i managed to fix this issue but i wanted to document it here for any others whom might have similar problems. I'm running a mediatemple (dv) rage server. monit started sending me alerts that i was having resource limitations on the server. logged into plesk and the CPU was pinned at 99.9%. Rebooted the server, catastrophe avoided... Not quite - all my rails apps were not loading My Setup ruby 1.8.6 Rails 2.3.5 w/ passenger installed as an apache module. I noticed a defunct ruby process so i killed and rebooted the server but runby continued to come back as defunct. Started trolling thru the apache log and i saw errors irt updating rubygems. i updated to the latest but then continued to get gem errors. Basically, I had to go thru all my apps and update any gems manually, reboot apache, and all was restored. Not really sure the cause of the issue but wanted to note it for posterity. Anybody else in the community ever have similar issues???

  • SQL Server Trouble with Rails

    - by Earlz
    Ok, I've been trying to get this to work like all day now and I'm barely any further from when I started. I'm trying to get Ruby On Rails to connect to SQL Server. I've installed unixODBC and configured it and FreeTDS and installed just about every Ruby gem relating to ODBC that exists. [earlz@earlzarch myproject]$ tsql -S AVP1 -U sa -P pass locale is "en_US.UTF-8" locale charset is "UTF-8" 1> quit [earlz@earlzarch myproject]$ isql AVP1 sa pass [ISQL]ERROR: Could not SQLConnect [earlz@earlzarch myproject]$ rake db:version (in /home/earlz/myproject) rake aborted! IM002 (0) [unixODBC][Driver Manager]Data source name not found, and no default driver specified (See full trace by running task with --trace) so, as you can see, tsql works, but not isql. What is the difference in the two that breaks it? /etc/odbc.ini [AVP1] Description = ODBC connection via FreeTDS Driver = TDS Servername = my.server UID = sa PWD = pass port = 1232 Database = mydatabase /etc/odbcinst.ini [TDS] Description = v0.6 with protocol v7.0 Driver = /usr/lib/libtdsodbc.so Setup = /usr/lib/libtdsS.so CPTimeout = CPReuse = FileUsage = 1 (and yes, I've made sure that the .so files exist) the relevant part in freetds.conf [AVP1] host = my.server port = 1232 tds version = 8.0 and finally, my database.yml development: adapter: sqlserver mode: odbc dsn: AVP1 username: sa password: pass Can anyone please help me before I pull all my hair out? I am using a 64 bit Arch Linux that is completely up to date.

  • Is it possible to convert a 40-character SHA1 hash to a 20-character SHA1 hash?

    - by ewitch
    My problem is a bit hairy, and I may be asking the wrong questions, so please bear with me... I have a legacy MySQL database which stores the user passwords & salts for a membership system. Both of these values have been hashed using the Ruby framework - roughly like this: hashedsalt = Digest::SHA1.hexdigest("--#{Time.now.to_s}--#{login}--") hashedpassword = Digest::SHA1.hexdigest("#{hashedsalt}:#{password}") So both values are stored as 40-character strings (varchar(40)) in MySQL. Now I need to import all of these users into the ASP.NET membership framework for a new web site, which uses a SQL Server database. It is my understanding that the the way I have ASP.NET membership configured, the user passwords and salts are also stored in the membership database (in table aspnet_Membership) as SHA1 hashes, which are then Base64 encoded (see here for details) and stored as nvarchar(128) data. But from the length of the Base64 encoded strings that are stored (28 characters) it seems that the SHA1 hashes that ASP.NET membership generates are only 20 characters long, rather than 40. From some other reading I have been doing I am thinking this has to do with the number of bits per character/character set/encoding or something related. So is there some way to convert the 40-character SHA1 hashes to 20-character hashes which I can then transfer to the new ASP.NET membership data table? I'm pretty familiar with ASP.NET membership by now but I feel like I'm just missing this one piece. However, it may also be known that SHA1 in Ruby and SHA1 in .NET are incompatible, so I'm fighting a losing battle... Thanks in advance for any insight.

  • deploy a sinatra app with passenger gives only 404, page not founds. Yet a simple rack app works.

    - by berkes
    I have correctly (or prbably not) installed passenger on apache 2. Rack works, but sinatra keeps giving 404's. Here is what works: config.ru: #app = proc do |env| return [200, { "Content-Type" => "text/html" }, "hello <b>world</b>"] end run app Here is what works too: Running the app.rb (see below) with ruby app.rb and then looking at localhost:4567/about and / restarting the app, gives me a correct hello world. w00t. But then there is the sinatra entering the building: config.ru require 'rubygems' require 'sinatra' root_dir = File.dirname(__FILE__) set :environment, ENV['RACK_ENV'].to_sym set :root, root_dir set :app_file, File.join(root_dir, 'app.rb') disable :run run Sinatra::Application and an app.rb require 'rubygems' require 'sinatra' get '/' do "Hallo wereld!" end get '/about' do "Hello world, it's #{Time.now} at the server!" end This keeps giving 404s. /var/logs/apache2/error.log lists these correctly as "404" with something that worries me: 83.XXXXXXXXX - - [30/May/2010 16:06:52] "GET /about " 404 18 0.0007 83.XXXXXXXXX - - [30/May/2010 16:06:56] "GET / " 404 18 0.0007 The thing that worried me, is the space after the / and the /about. Would apache or sinatra go looking for /[space], like /%20? If anyone knows what this problem relates to, maybe a known bug (that I could not find) or a known gotcha? Maybe I am just being stupid and getting "it all wrong?" Otherwise any hints on where to get, read or log more developers data on a running rack, sinatra or passenger app would be helpfull too: to see what sinatra is looking for, for example. Some other information: Running ubuntu 9.04, apache2-mm-prefork (deb), mod_php5, ruby 1.8.7, passenger 2.2.11, sinatra 1.0

  • Rails 2.3.2 trying to render ERB instead of HAML

    - by c00lryguy
    Rails is suddenly trying to render ERB instead of Haml and I can't figure out why. I've created new rails projects, reinstalled Haml, and reinstalled Rails. Here's exactly the steps I take when making my application (Rails 2.3.2): rails> rails test rails> cd test rails\test> haml --rails . rails\test> ruby script\generate model user email:string password:string rails\test> ruby script\generate controller users index rails\test> rake db:migrate Here's what the UsersController looks like: class UsersController < ApplicationController def index @users = User.all end end My routes: ActionController::Routing::Routes.draw do |map| map.resources :users end I now create views\users\index.html.haml: %table %th(style="text-align: left;") %h1 Users - for user in @users %tr %td= user.email %td= user.password Annnd run the server... I navigate to localhost:3000\users and I get this error message: Template is missing Missing template users/index.erb in view path app/views For some reason Rails is trying to find and render .erb files instead of .haml files. vendor\plugins\haml\init.rb exists, untouched. I've reinstalled Haml (Pretty Penny) multiple times and still get the same results. I've also tried adding config.gem 'haml' to my environment.rb but this also doesn't work. I can't figure out why suddenly rails will not render haml for me.

  • XMPP4R Callbacks dont seem to work

    - by Sid
    Im using xmpp4r and trying to get the hang of a basic chat feature that I wish to implement later in my Rails app. My fundamentals on Ruby Threads is still a bit shaky so I would appreciate any help on this. Though I register the callback i dont get a response from my gmail account. I am able to send a message but my ruby program terminates. In order to prevent it from terminating I tried to stop on of the threads in the program but I cant seem to get it working. require 'rubygems' require "xmpp4r/client" require "xmpp4r/roster" include Jabber def connect client = Client.new(JID::new("[email protected]")) client.connect client.auth("test") client.send(Presence.new.set_type(:available)) client end def create_message(message, to_email) msg = Jabber::Message::new(to_email, message) msg.type = :chat msg end def subscribe(email_id) pres = Presence.new.set_type(:subscribe).set_to(email_id) pres end client = connect roster = Roster::Helper.new(client) roster.add_subscription_request_callback do |item,pres| roster.accept_subscription(pres.from) end def create_callback(client) $t4= Thread.new do client.add_message_callback do |m| puts m.body puts "................................Callback working" end end end puts "Client has connected" msg = create_message("Welcome to the winter of my discontent", "[email protected]") client.send(msg) create_callback(client) def check(client) $t3 = Thread.new do loop do puts "t3 still running........."

  • Which apache worker to use with passenger and how?

    I've this config in my apache2.conf <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 150 MaxRequestsPerChild 0 </IfModule> # worker MPM # StartServers: initial number of server processes to start # MaxClients: maximum number of simultaneous client connections # MinSpareThreads: minimum number of worker threads which are kept spare # MaxSpareThreads: maximum number of worker threads which are kept spare # ThreadsPerChild: constant number of worker threads in each server process # MaxRequestsPerChild: maximum number of requests a server process serves <IfModule mpm_worker_module> StartServers 2 MaxClients 15 MinSpareThreads 4 MaxSpareThreads 5 ThreadsPerChild 15 MaxRequestsPerChild 50000 </IfModule> Now I'm confused here. Which module gets loaded on which conditions? The phusion guys have suggested to use the worker module. Since both are present in apache conf file, do I have to comment the mpm_prefork_module or leave it as it is? Following is my passenger conf file for apache: LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4/ext/apache2/mod_passenger.so PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4 PassengerRuby /usr/bin/ruby1.8 PassengerMaxPoolSize 3 PassengerPoolIdleTime 999999 RailsFrameworkSpawnerIdleTime 0 RailsAppSpawnerIdleTime 0 I'm running just a single Rails 2.3.2 app on 256MB slice at slicehost. I'm not quite satisfied with the performance yet. Are the settings above are any good??

  • what is the point of heterogenous arrays?

    - by aharon
    I know that more-dynamic-than-Java languages, like Python and Ruby, often allow you to place objects of mixed types in arrays, like so: ["hello", 120, ["world"]] What I don't understand is why you would ever use a feature like this. If I want to store heterogenous data in Java, I'll usually create an object for it. For example, say a User has int ID and String name. While I see that in Python/Ruby/PHP you could do something like this: [["John Smith", 000], ["Smith John", 001], ...] this seems a bit less safe/OO than creating a class User with attributes ID and name and then having your array: [<User: name="John Smith", id=000>, <User: name="Smith John", id=001>, ...] where those <User ...> things represent User objects. Is there reason to use the former over the latter in languages that support it? Or is there some bigger reason to use heterogenous arrays? N.B. I am not talking about arrays that include different objects that all implement the same interface or inherit from the same parent, e.g.: class Square extends Shape class Triangle extends Shape [new Square(), new Triangle()] because that is, to the programmer at least, still a homogenous array as you'll be doing the same thing with each shape (e.g., calling the draw() method), only the methods commonly defined between the two.

  • ActiveRecord/sqlite3 column type lost in table view?

    - by duncan
    I have the following ActiveRecord testcase that mimics my problem. I have a People table with one attribute being a date. I create a view over that table adding one column which is just that date plus 20 minutes: #!/usr/bin/env ruby %w|pp rubygems active_record irb active_support date|.each {|lib| require lib} ActiveRecord::Base.establish_connection( :adapter => "sqlite3", :database => "test.db" ) ActiveRecord::Schema.define do create_table :people, :force => true do |t| t.column :name, :string t.column :born_at, :datetime end execute "create view clowns as select p.name, p.born_at, datetime(p.born_at, '+' || '20' || ' minutes') as twenty_after_born_at from people p;" end class Person < ActiveRecord::Base validates_presence_of :name end class Clown < ActiveRecord::Base end Person.create(:name => "John", :born_at => DateTime.now) pp Person.all.first.born_at.class pp Clown.all.first.born_at.class pp Clown.all.first.twenty_after_born_at.class The problem is, the output is Time Time String When I expect the new datetime attribute of the view to be also a Time or DateTime in the ruby world. Any ideas? I also tried: create view clowns as select p.name, p.born_at, CAST(datetime(p.born_at, '+' || '20' || ' minutes') as datetime) as twenty_after_born_at from people p; With the same result.

  • rails Rake and mysql ssh port forwarding.

    - by rube_noob
    Hello, I need to create a rake task to do some active record operations via a ssh tunnel. The rake task is run on a remote windows machine so I would like to keep things in ruby. This is my latest attempt. desc "Syncronizes the tablets DB with the Server" task(:sync => :environment) do require 'rubygems' require 'net/ssh' begin Thread.abort_on_exception = true tunnel_thread = Thread.new do Thread.current[:ready] = false hostname = 'host' username = 'tunneluser' Net::SSH.start(hostname, username) do|ssh| ssh.forward.local(3333, "mysqlhost.com", 3306) Thread.current[:ready] = true puts "ready thread" ssh.loop(0) { true } end end until tunnel_thread[:ready] == true do end puts "tunnel ready" Importer.sync rescue StandardError => e puts "The Database Sync Failed." end end The task seems to hang at "tunnel ready" and never attempts the sync. I have had success when running first a rake task to create the tunnel and then running the rake sync in a different terminal. I want to combine these however so that if there is an error with the tunnel it will not attempt the sync. This is my first time using ruby Threads and Net::SSH forwarding so I am not sure what is the issue here. Any Ideas!? Thanks

  • BCrypt says long, similar passwords are equivalent - problem with me, the gem, or the field of crypt

    I've been experimenting with BCrypt, and found the following. If it matters, I'm running ruby 1.9.2dev (2010-04-30 trunk 27557) [i686-linux] require 'bcrypt' # bcrypt-ruby gem, version 2.1.2 @long_string_1 = 'f287ed6548e91475d06688b481ae8612fa060b2d402fdde8f79b7d0181d6a27d8feede46b833ecd9633b10824259ebac13b077efb7c24563fce0000670834215' @long_string_2 = 'f6ebeea9b99bcae4340670360674482773a12fd5ef5e94c7db0a42800813d2587063b70660294736fded10217d80ce7d3b27c568a1237e2ca1fecbf40be5eab8' def salted(string) @long_string_1 + string + @long_string_2 end encrypted_password = BCrypt::Password.create(salted('password'), :cost => 10) puts encrypted_password #=> $2a$10$kNMF/ku6VEAfLFEZKJ.ZC.zcMYUzvOQ6Dzi6ZX1UIVPUh5zr53yEu password = BCrypt::Password.new(encrypted_password) puts password.is_password?(salted('password')) #=> true puts password.is_password?(salted('passward')) #=> true puts password.is_password?(salted('75747373')) #=> true puts password.is_password?(salted('passwor')) #=> false At first I thought that once the passwords got to a certain length, the dissimilarities would just be lost in all the hashing, and only if they were very dissimilar (i.e. a different length) would they be recognized as different. That didn't seem very plausible to me, from what I know of hash functions, but I didn't see a better explanation. Then, I tried shortening each of the long_strings to see where BCrypt would start being able to tell them apart, and I found that if I shortened each of the long strings to 100 characters or so, the final attempt ('passwor') would start returning true as well. So now I don't know what to think. What's the explanation for this?

  • RSpec: Can't convert Image to String when using Nested Resource.

    - by darrint
    I'm having trouble with and RSpec view test. I'm using nested resources and the model with a belongs_to association. Here's what I have so far: describe "/images/edit.html.erb" do include ImagesHelper before(:each) do @image_pool = stub_model(ImagePool, :new_record => false, :base_path => '/') assigns[:image] = @image = stub_model(Image, :new_record? => false, :source_name => "value for source_name", :image_pool => @image_pool) end it "renders the edit image form" do render response.should have_tag("form[action=#{image_path(@image)}][method=post]") do with_tag('input#image_source_name[name=?]', "image[source_name]") end end end The error I'm receiving: ActionView::TemplateError in '/images/edit.html.erb renders the edit image form' can't convert Image into String On line #3 of app/views/images/edit.html.erb 1: <h1>Editing image</h1> 2: 3: <% form_for(@image) do |f| %> 4: <%= f.error_messages %> 5: 6: <p> app/views/images/edit.html.erb:3 /opt/dtcm/railstest/lib/ruby/gems/1.9.1/gems/rspec-rails-1.3.2/lib/spec/rails/extensions/action_view/base.rb:27:in `render_with_mock_proxy' /opt/dtcm/railstest/lib/ruby/gems/1.9.1/gems/rspec-rails-1.3.2/lib/spec/rails/example/view_example_group.rb:170:in `render' Looking at the rails code where the exception occurs is not very revealing. Any ideas on how I can narrow down what is going on here? One thing I tried was calling form_for directly from the example and I got a different error griping about lack of 'polymorphic_path' defined on Spec::Rails::Example::ViewExampleGroup::Subclass_4:0xblah. Not sure if that actually means anything.

  • Capistrano + Git + DreamHost

    - by Michael Sync
    Hello, I'm trying to deploy my rails application by using Passenger and Capistrano on Dreamhost. I'm using Git as a version control and we bought an account from GitHub. I have installed all required gems, Passenger and Capistrano in my local machine and I have cloned the repository of my project from GitHub in my local machine as wel. According to Dreamhost support, they have Passenger, Ruby, Rails and etc on their server as well. I'm currently following this article http://github.com/guides/deploying-with-capistrano for my deployment. The following is my deploy.rb. default_run_options[:pty] = true ssh_options[:forward_agent] = true # be sure to change these set :user, 'gituser' set :domain, 'github.com' set :application, 'MyProjectOnGit' #[email protected]:MyProjectOnGit.git # the rest should be good set :repository, "[email protected]:MyProjectOnGit.git" set :deploy_to, "/ruby.michaelsync.net/" set :deploy_via, :remote_cache set :scm, 'git' set :branch, 'master' set :git_shallow_clone, 1 set :scm_verbose, true set :use_sudo, false set :git_enable_submodules, 1 server domain, :app, :web role :db, domain, :primary => true set :ssh_options, { :forward_agent => true } namespace :deploy do task :restart do run "touch #{current_path}/tmp/restart.txt" end end When I run "cap deploy", I'm getting the error below. [deploy:update_code] exception while rolling back: Capistrano::ConnectionError, connection failed for: github.com (Net::SSH::AuthenticationFailed: gituser) connection failed for: github.com (Net::SSH::AuthenticationFailed: gituser) Thanks in advance..

  • Pre-packaged Rails applications

    - by Craig
    Seems like most Rails applications have similar 'base' functionality. As such, it seems that there would be value in having pre-build Rails applications at various functionality points such as: basic User model with authentication using Authlogic #1 + openid integration #2 + authorization using declarative_authorization #3 + Administration module #4 + a Profile model Themes (useful stylesheets and such) Friendship model Geocoding ... In addition to the basic MVC stuff, these applications would include: testing harnesses seed data git support One could choose start from any of these functionality points. Other than the sample application that are available with the various gems/plugins, are there projects such as these? If not, I would certainly be willing to contribute what I have.

  • RMagick transparent_color deprecated? What's the alternative?

    - by user315975
    I'm developing an app that does a fair amount of generating transparent pngs on the fly. These are used as overlays, to show areas of interest in a graphic, so they have to have transparent backgrounds. I am developing in Ruby on Rails, deploying on Heroku. What works fine in development is not working in production. I get this error when I call a drawing routine using RMagick: NotImplementedError (the `transparent_color=' method is not supported by ImageMagick 6.2.4): /usr/local/lib/ruby/gems/1.8/gems/rmagick-1.15.17/lib/RMagick.rb:1691:in `transparent_color=' I'm using RMagick version 2.12.1 on the development machine, but I'm not exactly certain how to discover the version of ImageMagick that it's running, so I'm not sure if this is a case of my local code being behind or ahead. I'm hoping behind, because perhaps then there'll be a replacement for this call. Does anyone know what the fix is here? What's required to generate a transparent background, if not the call I'm using? I can't find this in the documentation: in fact, it was on a third-party site that I found mention of this capability.
