I would not care so much, but two of my ex-SAIC bosses Gene Ray and Jack McDougle (both very good guys) helped found Titan. Way to go!

More thoughts on using multiple programming languages

I have had the opportunity to use a few technologies for mixing and matching programs written in different programming languages in the last month: CORBA, SOAP, and the simple XML over HTTP (i.e., REST like RPC).

Sure, it is a hassle using RPC compared to building large monolithic applications, but I find that not only are different programming languages best for some tasks, but often key utility libraries are available only for some languages.

While I really like CORBA, and I have CORBA support in Java and Smalltalk, other languages which I find useful like Common LISP and Prolog either don't have CORBA support, or it is expensive.

Although not a perfect solution, I keep coming back to writing HTTP servers that use URL encoding to specify a "function name" and arguments - usually returning an XML payload makes sense.

In principle, SOAP is a better way to go, but XML over HTTP is much easier to implement.

The linked article seems well balanced and makes a lot of sense to me.

I think that Haaretz is one of the better sourrces of news in Israel - and this article reinforces that opinion.

There is a large minority of Israelis who strongly disagree with the actions of the right wing government - this article reflects this rational opinion.

The link is to HP's web site for their free semantic web tools.

Check out Jena.

MSNBC has a fascinating interactive history of the Israeli settlements.

I thought that the settlements were few and far between - I was wrong about that.

The West Bank is covered with Israeli settlements (which, by the way, I think are illegal under international law).

Anyway, check out the linked MSNBC site and watch the display while choosing: 1914 -> 1948 -> 1977 -> Present time.
