I’ve been learning a lot about Web development these days: Dojo and Ajax, in particular. It’s incredible what you can do in Javascript nowadays, sophisticated desktop applications running inside a Web browser. I am spending a lot of time building a complex prototype application that has many features associated with desktop programs, including graphics, pop-up dialogs, menus, and more.
I’ve also been learning a lot about the intricacies Brans-Dicke gravity and about the parameterized post-Newtonian (PPN) formalism. Brans-Dicke theory is perhaps the simplest modified gravity theory that there is, and I have to explain to someone why the gravity theory that I spend time working on doesn’t quite behave like Brans-Dicke theory. In the process, I find out things about Brans-Dicke theory that I never knew.
And, I’ve also been doing a fair bit of SCPI programming this month. SCPI is a standardized way for computers to talk to measurement instrumentation, and an old program I wrote used to use a non-standard way… not anymore.
Meanwhile, in all the spare time that I’ve left, I’ve been learning Brook+, a supercomputer programming language based on C… that is because my new test machine is a supercomputer, sort of, with its graphics card that doubles as a numeric vector processor capable in theory of up to a trillion single precision floating point instructions per second… and nearly as many in practice, in the test programs that I threw at it.
I’m also learning a little more about the infamous cosmological constant problem (why is the cosmological constant at least over 50 orders magnitude too small but not exactly zero?) and about quantum gravity.
As I said in the subject… busy days. Much more fun though than following the news. Still, I did catch in the news that Susan Boyle lost in Britains Got Talent… only because an amazing dance group won:
