then perhaps you should take a look at experimentalstuff.com - sun's site for experimental code. lots of it is opensource including an entire operating system (chorus os).

looks like a committment to opensource to me.

...called the Interoperability Prototype for Liberty.

Just to see what would turn up, I ran PMD over the source code - it came out pretty clean.

Okay, a lot of pro-Linux studies have their own problems (frankly, I don't put much stock in "studies" any more, especially vendor-funded ones).

I've been drooling over embedded platforms for nearly a decade--jeeze, I hate the look of that word combination, but, moving right along...

The truth is that I'm a fan of all of them. Here, in no particular order, are some links.
Lynx is a link on the bottom left at this page.
An old standby, which really isn't that different from GNU HURD.
Sun's "telephone system"
This might very well be the most generic.
I even like this kind of thing, which displaces quite a bit of O/S purpose.

And why shouldn't I! Why shouldn't you? Well, the truth is that neither is a rhetorical question. That is my point. There are too many specific considerations, many of which are important, to declare dogmatically that any one operating system ought to be embedded--or even embedded "most often". This is not efficient executive decision-maker thinking. This kind of "debate" is about topics that permit/encourage the deadness of brains of said executives. (And we wonder why tech equity share prices stay in the gutter?)

Scott McNealy said that, but the vision was implemented by others. CMU's Mach (1985), Andrew Tanenbaum's Amoeba (1986), and Plan 9 (1987) were OSes that made a network into a computer.

To be fair, Sun does have ChorusOS , but that seems to have died the death (i.e. gone Sun Public Source) despite Scott's best intentions.

Our company is doing a mixture of Java and C++ so we are using make. I came across a fantastic conditional compiler written by some developer at sun.. JavaMake It can be easily integrated with Ant and it evaluates the bytecode of the updated files to see what signatures have changed. It then recompiles anything using those signatures if they weren't changed as well. It works *wonderfully*. The only limitation is compile time constants. If you change the name or type of a constant, it has to recompile the whole project because the Java bytecode only has the substituted value, not a reference to the variable.

Check it out. It can save a *lot* of time.

I had thought it was the product of Chorus,a French company, but it looks like Sun bought them out in 1997.

The above page says that it isn't being sold any more, but IS available as a free, open source version.

Yippee!

Interestingly, I notice when the techs at work log in to our Alcatel OmniPBX, they are greeted by a banner indicating that it uses GNU software from the Linux operating system.

Either the front end box is running Linux, or, more likely, the fact that ChorusOS incorporates GNU tools, in which case strictly speaking the software is really from the GNU project, but interesting nonetheless.
