The value I see in Tetrad is to bring different concepts (4 Laws) together into a Gestalt. I suppose one can over think these, but don’t believe that there is only one answer. Each brings their own insights and thoughts into the process.

I did not write up (push) the other Tetrad’s because I wanted to encourage comment and discussion. To me the surprising discovery was that Facebook and Twitter are very different media though they are based upon the same over all platform, the Internet.

With Twitter one is creating a persona, an image of themselves for presentation to the world by the news and insights one wants to present and the articles and concepts they chose to share. The Eloi from the Time Machine were devoid of personality or persona. The fact that Justin Bieber takes up 14% of Twitter bandwidth or Britney Spears and Madonna in Search and Video before him is maybe an indication of this.

However I can see other aspects to Facebook and Twitter that could be developed in the Tetrad. For example forming and applying networks that could be explored providing a very different view. Perhaps more thought should be brought to this.

Thanks again for your comment. I encourage you and everyone to continue the discussion.

Perhaps you miss understood the intent of the article. The clue is in the title. “Upside down” as in alternative, contrarian, non-traditional, or dual approach to the typical presentation of concurrency. The traditional view focuses primarily on achieving parallelism as an allusion of concurrency. What I am suggesting in the article is that there is a dual approach where instead of starting with one shared state and breaking it down into critical sections, one can start by assuming no shared state and introduce shared views only when absolutely necessary. You maybe surprised how far you can get.

These are referred to as Share Nothing Architectures in DBMS. They allow for efficient distribution of processes over large networks of processors. By taking this contrarian view actually helps to build better CSP designs by understanding its inherent limitations and avoiding these in real world solutions. So I would encourage you to investigate further. Thanks for your interest and getting me back to my blog.
