When removing line 44 (redis.sadd) from common_passwords.rb the problem goes away.

def self.load_passwords
      passwords = File.readlines(PASSWORD_FILE)
      redis.sadd LIST_KEY, passwords[0,5000].map!(&:chomp)

      Rails.logger.error "Common passwords file #{PASSWORD_FILE} is not found! Common password checking is skipped."
    end

The 10k-common-passwords.txt file is there, and it's readable.

Anyone have any idea what is going on here?

I have been working on a heavily simplified plugin interface so its a lot easier for people to get started with extending Discourse.

For example:

Say you wanted to extend Discourse and add Ubuntu SSO to the dialog.

Place a file called plugin.rb in the directory plugins/ubuntu_sso

###plugins/ubuntu_sso/plugin.rb

# name: discourse-ubuntu
# about: ubuntu login support for Discourse
# version: 0.1
# authors: Sam Saffron, Marco Ceppi

auth_provider :title => 'with Ubuntu',
              :authenticator => Auth::OpenIdAuthenticator.new('ubuntu','https://login.ubuntu.com', trusted: true),
              :message => 'Authenticating with Ubuntu (make sure pop up blockers are not enbaled)',
              :frame_width => 1000,   # the frame size used for the pop up window, overrides default
              :frame_height => 800

register_css <<CSS

.btn-social.ubuntu {
  background: #dd4814;
}

.btn-social.ubuntu:before {
  font-family: Ubuntu;
  content: "U";
}

CSS

Run bundle exec rake assets:precompile
Restart you services.

Done, you have working Ubuntu SSO.

This interface is still not complete, as I finalize it I will be adding more examples here.

The /plugins directory is ignored by git so you can place your extensions there safely.

Longer term plans

1. Possibly use a Rails::Engine for greater flexibility
2. More hooks
3. Admin UI to enable or disable plugins (with multisite support)
4. Central plugin repo
5. External gem dependencies

If you are interested in extending the interface etc, let me know.

Hi guys,
our community is trying to move from vbulletin forum to discourse and we need your help!
We just published the discourse forum to test it but we are facing some performance issues.

We need to understand how powerful the server should be to manage our users and tweak the discourse installation to get rid of all errors we are facing.

Here the specs of the server:
VPS on Digital ocean 1 CPU 1GB RAM 30 SSD
Discourse_Docker by sam on Docker 0.7 Ubuntu 13.04 x64

Upgrading to 0.9.8.1 to resolved the overload issue with sidekiq only partially.

As you can see the load is still high but not due anymore to the sidekiq daemons.

Right the traffic of the new discourse installation is really small as you can see from stats:

1. We see some worrying errors in the log:

EOF errors are related to bad gateways errors trying to inserting new posts.

1. Monitoring the CPu of the server while posting, it spikes considerably with one user inserting a post and then we constantly get bad gateway error and some times the server is not responding to pings due to high load.
   

2. After the boostrap phase, we see this king of errors:
   df: Warning: cannot read table of mounted file systems: No such file or directory

I strongly believe docker is the way to semplify the discourse deploy, but as you can see it needs still some improvements. Helping us would help other people how are approching to discourse project without being RoR gurus.

Thanks in advance for any help.

I do my own analytics with Piwik, a FOSS self-hosted Google Analytics-like platform. It relies on a similar bit of javascript in the <head> section of each page.

Obviously this is a low-priority question, but might it be possible to have Discourse support Piwik as an alternative to GA in the site settings? Actually, all it would take is the ability to inject the javascript code into each page's <head> (or in the <body>—that works fine, too).

Thanks

[I don't know if this is a bug, or if we just don't really understand how it should work, recategorise at will]

We already noticed this during the development of the AdSense plugin, but our test environment wasn't very clean, so we blamed that. This weekend we installed a new test server and the problem still seems to exist.

When installing a plugin using rake plugin:install , followed by rake assets:precompile and a restart, the client translations (from config/locales/client.en.yml in the plugin directory) are often missing.

We found we had to do a rm -rf public/assets/application* and clean tmp/cache as well before precompiling the assets in order to make sure the assets are recompiled to include the new client translations. Even rake assets:clean doesn't seem to do the trick. Such a harsh delete causes downtime for the forum while precompiling the new asset files, so this is not really a desired way of doing things.

There's probably something I'm missing here, since I'm not very familiar with the asset pipeline. As far as I understand, those files must be added to the Sprockets manifest. But I'm clueless how this is done, especially with plugins. And I'm even more clueless how Sprockets does seem to find those files after all when the compiled assets are removed.

Here is a list of the type of advertising options I would like in Discourse. Perhaps others can add to this list. I'm not a software engineer so I don't know how difficult these are - but perhaps they could be implemented via a Plugin.

Banner Ads Options

• Horizonal Banner ads placed between messages at the "list" view (Admin can specify how frequently ads show up)
• Horizonal Banner ads placed between messages in the Message view when there are multiple postings (Admin can specify how frequently ads show up)
• Horizonal Banner ad placed below the horizontal line (and above the "Invite Friends to Reply" button, when in Message view
• Vertical banner ads on right of screen when in Message view. Some people have expressed the desire to have a floating 300 by 250 ad. Another approach might be periodically placed ads down the right side (repeats of the same or different ads every second or third message or so). It would be nice to be able to vary the frequency of the ads on the pages from 100% of pages to 1% of pages (see research below).
• Support for Amazon affiliate ads - I'm thinking specifically of books, in the small text or small image type of ads. These could go either on the right side of the messages, or

Email Ads

• Banner or Text / adwords ads at the top and/or bottom of outgoing emails to users (digest or notification emails)
• Bulk email ad send to mailing list/subscriber list - with field to paste HTML into, to send. Periodically it would be nice to be able to send out special notifications and/or advertisements to users - directly from Discourse. With reporting on "opens", etc. similar to mailchimp, etc.

If Discourse does get some standard integration of advertising options (i.e. banner or text ads) - it would be very nice if it reflected the current research in this area:

http://www.bps-research-digest.blogspot.co.uk/2011/10/are-we-really-blind-to-internet-banners.html10

The lessons for web advertisers are clear: don't advertise on every page, vary ad location, and make sure the ad topic is congruent with the web-site content.

Considering I want to add a user to a private category.

Right now I have to add a person to a (security) group in admin and then add this group to the category in frontend.

I'd like to grant moderators the permission to add users to groups within the second tab of frontend's Edit Category screen without ever entering /admin, whereas I'd love to interact with group memberships in /admin/users/*/.

Is there any other discussion going on related to this idea?
