      Okay, I have a low opinion of Slashdotters that insist that software release announcements should stay on Freshmeat. I want to *know* when the next Linux kernel release and the next minor release of GNOME is, and it's big, discussable news.

      However, this is a bugfix release of an obscure package. I realize that the editor was probably feeling more than a little whimsical, but dammit..can't Slashdot have an "Oddball" category? Stuff that the editor can dump things into if he sees something that whets his fancy, but is wildly unfit to go into the "News for Nerds" section? Things like "Lindows CEO Claims Microsoft CEO Porks His Sister" or "Random Extremely Obscure Package 10.4.6 Released" could go? It'd be a great grabbag for April 1.

    While certainly generous, the Cougaar license is designed specifically to prevent anyone from profiting from the sale of the software:

    3. Licensee may use, sell or give away the Cougaar Software or any Derivative Work, alone or as a component of an aggregate software distribution containing Licensee Software, Cougaar Applications and/or programs from several different sources. No royalty or other fee is required. If Licensee sublicenses the Cougaar Software or Derivative Works, Licensee may charge fees for warranty or support, or for accepting indemnity or liability obligations of customers, provided that Licensee does not charge for the Cougaar Software or Derivative Work.

      Not quite. Before you get your panties in a bunch, look closer.

      It's quite explicit that you can "sell or give away the Cougaar Software or any Derivative Work". Case solved. You can sell it.

      The second term is a bit puzzling. "If Licensee sublicenses the Cougaar Software or Derivative Works...Licensee does not charge for the Cougaar Software or Derivative Work". The key word here is "sublicenses".

      You can sell the software or its derivatives all you want. Only if you sublicense it are you forbidded to charge for the software itself (though you may certainly charge for the media, bandwidth, support, manuals, etc). When you sublicense, the recipient is getting the license from YOU, not from the original author. This is a subtle distinction, and one few ever make in the Free Software World. What does it mean?

      Not being a lawyer, I suspect it's primarily to mollify the legal types. Note that sublicensing is required to offer indemnity or liability (even if it weren't explicitly stated in the license). I suspect that this means if you create a business off of the software, you cannot sell the software itself, but only the warranty and support.

      The license is Free as in FSF. Don't worry about it.
      • "The license is Free as in FSF. Don't worry about it."

        The GPL lists [gnu.org] free software licenses, if you want to check their opinion on a license. Cougaar isn't listed.

        The open source initiative [opensource.org] also lists licenses which qualify to be called Free Software. Cougaar isn't listed.

        Is Cougaar using one of the listed licenses, or has it been sent to GNU for analysis?

Morality isn't defined by Papal Bulls any more than software freedom is defined by the pronouncements of RMS. The reason Cougaar isn't listed is because it's new and the FSF and OSI haven't gotten around to stamping it with their imprimaturs.

    • The part that makes the Cougaar license unfree by my standards is the requirement that derivative works be sent to the original authors. If they recommended this practice, or encouraged it, I wouldn't have a problem. Requiring it, though, will get to be a burden in the long run, particularly if lots of software makes such a requirement.

    Essentially, agent-based computing is P2P used in a positive way -- multiple redundant systems working together to achieve a common goal, much as is done by ants in a colony.

    Like the Internet, but with other goals than networked communications. I think this is the sort of thing that will finally bring the convergence that was always talked about in regards to the Internet (an alarm clock, coffee, toaster, car starter, etc. that are aware of your schedule, not unlike the opening scene of Back To The Future).

      • One of the goals of agent systems is to allow agents to run on other people's computers. Of course if you let your computer run someone else's agent, then you want some kind of assurance that the agent isn't malicious. Because of the Halting Problem, you can never prove that an agent isn't malicious without running it -- however statically typed languages allow you to make way more assurances (if not proofs) about what a program is going to do. Unfortunately, Erlang isn't statically typed; therefore Erlang

    Java is not the language designed for distributed agents. For that I would use Erlang or Mozart or even Mercury, but not Java.

    In those languages distributed programming itself is solved more elegant and error proof. Besides, they have very strong mechanism of constraint logic. Even more - distributed constraint logic. And no need to repeat that functional programming languages are more effective for complicated logical tasks.

    Oppositely, in Java the agent developer feels like in assembly. Don't repeat me the mantra about the garbage collector: functional programming languages have it since 1957 (first Lisp).

    Well, if brains of their project decision makers are already corrupted by procedural programming (or even worse - by merketing hype of Java) then nothing can fix that. It's just one more government-wasted effort.

      In a philosophical sense, I agree (somewhat), but in a pragmatic sense I think you're wrong.

      While people have certainly been programming mobile agents in many languages for a very long time, there's nothing wrong with implementing them in Java. Java is a fairly nice language with a good security model and portable bytecode. Having used both to write agents, I can say that it's not quite as nice for writing mobile agents as Telescript (the language that General Magic designed for implementing mobile agents), but it's not bad. Sure, SmallTalk or Lisp are simpler and cleaner in many ways, and Erlang, etc., have some nice, though somewhat esoteric advantages, but Java has the fairly reasonable advantages that it's a widely known and extremely well supported language.

      And as for preferring declarative programming to procedural programming, well, all I can say is that different models suit different kinds of problems, and different kinds of programmers. Changing both programming languages and programming paradigms (i.e. procedural to declarative) and throwing mobile agents into the mix) is extemely challenging to a development team. Not that it can't be done, but it's way harder (for a large team) than just introducing mobile agents implemented in a language everyone knows. Take one step at a time, or you lose people. I know, back in the 80's I was on a number of large Smalltalk projects, and making the leap to OOP, Client/Server and learning Smalltalk all at once was a barrier than many engineers couldn't hurdle. Sure, the stars got it, and were amazingly productive, but everyone else was blocked.

      That being said, if you have a small team of stars, and a project that doesn't require a larger team, go for it -- you may be extremely successful. But I don't think that makes anyone who decides to implement mobile agents in Java wrong, just a little less daring. :-)
    • If it was written in Erlang or Mozart or Mercury, nobody would use it, since nobody knows anything about these languages.

      Sure, in Java it is probably harder to write these kinds of distributed agents, but a lot more people can hack all kinds of interesting stuff onto the agents just because they can read Java code.
