Webinar - OpenSSO in the Clouds

I'll be reprising my OpenSSO in the Clouds presentation as part of BrightTALK's Cloud Computing Summit at 2pm next Thursday, January 29th 2009. Click here to attend and discover how OpenSSO fits into the cloud computing model.

OpenSSO Halloween Tab Sweep

I wish I could say there were spooky goings on this week in OpenSSO, but you'll have to settle for more adoption news and some fun stuff with OpenSSO and Amazon EC2...

  • First up this week, on the OpenSSO Users mailing list, we had an interesting email from Romanov Vladimir, of the R&D department of Russian telecommunications operator Scartel, saying that they are using OpenSSO as the authentication mechanism for their new Yota WiMax network. We're looking forward to hearing more as they move Yota from test mode into production.
  • Staying in Eastern Europe, I noticed the work going on at the Budapest University of Technology and Economics (BME), where they are also using OpenSSO for authentication - a nice diagram and some information on the architecture; unfortunately, Google Translate doesn't yet stretch to Hungarian, although Adam Lantos of HME (a regular participant on the mailing list) says he'll send some information in English soon.
  • Finally, Mike Hortobagyi, up in Canada, writes today about an experiment I ran last night, deploying OpenSSO onto GlassFish+OpenSolaris at Amazon EC2. Logically, it all should work ok, but it's great to try something like this and see it actually running up in the cloud. It took me less than 45 minutes to get OpenSSO and the Fedlet running, including uploading the OpenSSO WAR file to the EC2 instance. I'll leave the instance up for a few days so you can go play - try out the Fedlet (click the link to login, username demo, password changeit), or even the federation validator (same username/password). NOTE - it's a little confusing, since I gave OpenSSO and the Fedlet the same hostname, but they are independent web applications, with no shared state. You can see all the gory SAML details (WoooOOOooo! Spooky!) in the Fedlet page after you login. Go give it a try; if you get a host not found, or page not found, error, I've likely taken the instance down... I can't keep paying $0.10 per hour forever, you know!

So, there you go - I managed to squeeze in a spooky reference in the end... Happy Halloween, everyone!

Blog Bling - Part 2 - Tag Cloud

Back in version 3.1, Apache Roller added support for tags. After Dave Levy blogged about tag clouds, I added one, based on his code:

#set($mytags = $model.weblog.getPopularTags(-1, 100))
#foreach ($tag in $mytags)
    #if ($tag.count > 2)
        <a class="tag s${tag.intensity}" href="$url.tag($tag.name)"
            title="$tag.count">$tag.name</a>
    #end
#end 

The code is quite simple - we create a set of popular tags, and, for each tag, if there are more than two blog entries with that tag, we create a link. The link's class is s1, s2...s5 based on the number of entries with that tag ('tag intensity'). The classes control the font size of the link:

<style type="text/css">
   .s1 {
   font-size:60%;
   }
   .s2 {
   font-size:80%;
   }
   .s3 {
   font-size:100%;
   }
   .s4 {
   font-size:120%;
   }
   .s5 {
   font-size:140%;
   }
</style>

That's all there is to it. I can link to all entries for a given tag - for example, http://blogs.sun.com/superpat/tags/opensso; there are even RSS feeds per tag - http://blogs.sun.com/superpat/feed/entries/atom?tags=opensso. You can also combine tags to get an intersection - http://blogs.sun.com/superpat/tags/opensso+saml. I've completely moved from categories to tags now - "It just works".

From Categories to Tags

I finally got round to completing Superpatterns' migration from categories (exactly one category per post) to tags (zero or more tags per post). You can see the tag cloud at the top of the page (if you're reading this through syndication you'll have to visit my actual web page to see this). The size of each tag name in the tag cloud relates to the number of blog entries with that tag. If you still want to navigate by categories, they are listed in the dropdown near the top of the column on the right.

Thanks to Rich Sharples for the category chooser tip and to Dave Levy for the tag cloud idea.
