Today we'll take a look at DDE support in VA Smalltalk. While DDE is an old way of doing inter-process communication, it still works well, and it's easy to use. To start, load the DDE-Examples package from the features tool, and then find the DDE-Examples Application:
Have a look at the DDETimeServer and the DDETimeClient. We'll be using those for the purpose of this example. Just create an instance of the server in a workspace:
Then create the client - you should see the time printing to the Transcript. All this example does is set up a topic for the client to find, and, when found, print to the Transcript:

Yet another reason I wish I was at ESUG this year - the people in that part of the Smalltalk community are great. They just sent me this (click through for the full size version):
Some time ago I described the steps I used to add Perl as a simple runtime and framework to Cloud Foundry. Since then many changes have taken place in Cloud Foundry and those steps no longer work. I now have something that works as of 30 August 2012. To see the changes go to my github repository and view the changes to vcap,vcap-staging, stager, and cloud_controller. Note that the recent refactoring of Cloud Foundry means that instead of isolating changes to one repository, we now make changes to four repositories.

Today we'll look at one of the simpler, but nicer features of ENVY in VA Smalltalk - the ability to compare two Applications for differences. While that's easily possible in any version control system, ENVY tracks everything - so we can even compare to versions we never released:
Simply pop up the context menu after selecting both apps, and pick the comparison option. Note that you can include (or exclude) sub applications:
What pops up is a differences browser, showing the places where the two applications differ. If you think you may have "lost" code in an un-released edition, ENVY makes it easy to recover it.
