SCATS is actually "Sydney Co-ordinated Adaptive Traffic System". About 10 years ago I visited the Road and Traffic Authority's control center for SCATS as part of a field day and it was an _old_ but successful system then!
They system was mostly written in assembler on PDP-11's and it was one of the reasons PDP-11's were still manufactured until quite recently.
SCATS was also installed in Hong Kong (probably other places as well) and there is some nasty traffic there. Last I heard they were rewritting it in C to make it more portable and maintianable so they could sell it into the US as well.
SCATS monitored traffic conditions (counting cars passing over the sensors) and comparing them to previous conditions - ie: yesterday, last week, last month and last year and adjusting allocated green time based on history.
Overall I think the traffic system works quite well in Oz.

Don't forget this issue has been simmering for a while now. Just as it took some time for FOSS to come into it's own with copyrights it will take also take time for Free and Open Patents to develop.
Personally I think PostgreSQL has been a great DB for some time, though the limiting factor IMHO has been portability.
As a developer I've stuck to mySQL or proprietary DB's for most of my projects because I don't always know the target platform.
I know older PostgreSQL versions ran on win32 under cygwin but you should try to explain why and how a customer has to install cygwin/postmaster etc. and you quickly understand it's just know worth the grief (notwithstanding performance issues as well )
A native Win32 implementation removes those limitaions - fantastic. Thanks all at PostgreSQL!
It sounds like your company was one of the early adopters of content management systems.
Most of the early CMS's built during the boom times they were large, very flexible and complex systems that tried to be all things for all people.
I think products like ATG Dynamo are great but they tend to be very over-engineered for small to medium size sites and maintaining them becomes a nightmare of inter-dependencies. It doesn't mean they won't perform and scale, just that you need very experienced people that knows all aspects of your site and CMS that can stay on top of 'expensive' function and minimise it's use. I find that a web site tends to go downhill when the experienced staff leave the project and amatuers start to hack stuff together without understanding potential problems. The fact is any web site on any platform is susceptible to this problem.
There are a lot of cheap/free products to ease your pain but you really need to research your options.
JSR 170 ( http://www.jcp.org/en/jsr/detail?id=147 ) seeks to standardise content management and could help you move forward and allow you to stay ahead on the CMS scene.
You may want to evaluate kroupware - though the name is horrible - they seem on the ball
From the kroupware site:
Kolab Server 1.0 is designed to be very scalable benefitting from already matured Free Software components like Cyrus IMAPd, Postfix, Apache and OpenLDAP
I've really got to take issue with some of your comments.
Your "victim" multi-billion dollar corp is not some filthy rich cat sitting in a mansion - out to rip off artists for every cent.
These corporations are held by many private investors - many of whom rely on these corporations to make a profit for thier income. You may even be one of those investors with your superannuation!
Don't delude yourself; _people_ get hurt by piracy. Feelings so feeling sorry or not for a corporation doesn't matter - corporation don't have feelings:)
You really should read the Jboss clustering doco. Then read them another 2 times.
It took about 1 week for us to set up our cluster with hot deploy and session replication working properly, though I think the next time round it would be a lot quicker.
I don't think there are really any big issues in setting up a cluster though to set up a _good_ app server cluster you need to understand how the clustering implementation of your app server works and decide what is best for your solution.
Unfortunately there are no magical "click here to cluster" buttons.
Have a look at http://www.wikipedia.com. It's a collaborative encyclopaedia that sounds very much like what you are after. It's really just a very big wiki site.
Also has version control features, peer review, tags etc etc.
If you were to look through previous post on CDMA vs TDMA (which is used by GSM) you will actually find that CDMA is indeed a better technology.
The 3G network is all based on CDMA since it is better at utilising bandwidth than TDMA. In fact most of Europe is slowly switching to CDMA though it will be an expensive process.
Qualcomm were right all along in the CDMA vs TDMA wars and now they should reap the benefits.
I think Iraq would do well to avoid all these problems and just move to 3G since they wouldn't have to support older phone/existing customer base.

We'll have to watch the movie "The Core" to the end to see how we fix it and that willl cause the extinction of our species.

There will be a time when these patents expire and the commons will be richer
Unfortunately the current SVN does not have complete support for WEBDAV. The next release will have enhanced WEBDAV support. Oz

eg's.
A female prime minister. Do you know how much better women are at networking then men? (not OSI type either fellas)
In NZ, it is illegal to restrict DVD players to regions (against consumer choice/paralell import laws ?..)
ADSL is old hat there. OZ is just pulling back the curtins.
Saying NO to Iraq...
How about kicking out the Israili spis - along with the ambassidor. I'm pretty sure we'd have given them passports. On ya NZ.
Don't sell NZ short. I think you guys are more on the ball than AU (too bad about the footy last night though).
Write an article about linux parking your car - post the video in WMV format...
Wouldn't it then be called gnu/hurd/linux?
There is also now a visual editor which should make development much easier.
Check it out at http://www.eclipse.org

That like an increase of 1.15 objects, up from 3.85. This is significant folks!!!! Gimmie more!!!
I didn't think so

I think you will find that SOAP is transport agnostic - ie you could use it over SMTP in an email message.
HTTP post is only one of the methods of delivering a SOAP envelope.
I haven't used Idea yet though I don't think they will be able to keep up with free and open source.
The new features planned for version 2.2 will surely blow them out of the water.
I think IBM have done a fantastic job to date and I hope it keeps up.

You really need to remember that slashdot is actually read outside the US as well where the Oscars is aired later in the evening.

I think that should be "re-lose the election"
