An XML based GUI that was powered by Ada including the use of protected
types and tasking could be much easier to use than Windows. This XML GUI
would also be much more reliable and efficient than Windows. 

Incidentally for normal mortals, I highly recommend EasyDesktop
www.microseconds.com
It employs a revolutionary GUI based on words. No icons. This makes it
very easy to use for those of us who were educated with a Western
alphabet.

As for the device drivers, writing them in Ada should facilitate their
reuse in multiple similar products, such as graphics boards. Eventually
XSL FOP could be part of the driver for both printers and graphics
boards.

Yes, I know that. That is real pain for Linux users. I signed a petition
some months ago directed to hardware manufacturers. It was a request
that
they notice growing Linux community and cooperate with Linux developers
to create device drivers. It was on
http://www.libranet.com/petition.html
but it seems it is closed now. However Polish version still exists. 
I hope they succeeded in collecting enough signatures to be noticed.

I do not claim that Linux is unusable for non-cs people, but there was
my observation. What I saw is, if they had no "click-click-do-all-for-me
-graphical-wizard", they fell lost/are too lazy(?)/want more convenience
in using system. It reminds me some post we had on CLA concerning GUIs
- "click-click-do-all-for-me-graphical-environment". Well...

Can you provide some details of XML guis or your thoughts? (or are they a
secret, incase someone rips off your ideas?)  This has popped up once or
twice here in the past, but there hasn't been much debate or indeed provided
information on the marrying of XML and a GUI.

Some OS developers in aod have taken an interest in UDI, Ada might be a
perfect partner to this but since I don't know what UDI specifies in terms
of types (if anything) I can't say whether there would be a great benefit in
a mix of the two.

Depending on how things go this summer, I hope to have a small microkernel
(think L4 small) finally in development.  Nick Roberts (right second name?
apologies to Nick if it isn't) is also planning a microkernel and it'll be
interesting to contrast the designs; which can only improve each others
efforts  (although it will help to bare in mind that the projects aim to
meet different requirements, with each design reflecting this.  Obvious, but
better said than left to chance).

Something I forgot which may be of interest to some is Devil (maybe it's
been mentioned before).  This is an idl for specifying programming
interfaces to hardware via abstractions.

At present the thing seems to have stalled, perhaps if there was enough
interest inria might put it into the open and it could be modified to
generate Ada code instead of C.

a page is available at
http://compose.labri.u-bordeaux.fr/prototypes/devil/specs/ for any who find
this concept interesting?

Re: [OT] Switching to Linux (was: Microsoft takes on ACT)

I have not looked at this extensively, but there are a couple of things that
might apply. XUL is a XML based markup language that aims at describing user
interfaces. I think XForms is something similar - but I don't think these
are highly solidified yet.

The basic idea here would be to have *some* (TBD) XML based markup language
that described the GUI. (Note that GtkAda does this) When the GUI is
interacted with, data could be returned to the application in some XML-based
format. (I think Bob Leif sees a strong correlation between the kinds of
data descriptions possible in XML and Ada so it would be fairly
straightforward to line up data coming out of XML and into Ada structures.
But I wouldn't want to presume to speak for Bob - read his Ada Letters
article.)

So it would be possible to envision an  Ada GUI building scenario that had
XML for the markup of the GUI (enabling the possible use of all sorts of
off-the-shelf tools) and XML for the transfer of data between the GUI engine
and the Ada application. This would give you platform independent GUI
capabilities and the possibility of having applications easily operate on a
client/server model. (The GUI-driving engine need not be on the same
platform as the back-end Ada application - they just need to transfer XML
between each other.)

Its an interesting idea but it would be a lot of work to pull it all
together.

I agree about reading my Ada Letters article. However, if someone is
motivated to do something, I will gladly send them a preprint. I agree,
"Its an interesting idea but it would be a lot of work to pull it all
together." Hopefully, it would be very profitable.

The creation of an XForms package that was bootstrapped using the
relevant parts of XSL and/or SVG would permit the development of an XML
based GUI. An Ada tool that creates a thick binding to a GUI, such as
Windows, could be morphed into an XML tool. It could even employ Adobe's
SVG browser plug-in. 

XMLSpy (www.xmlspy.com) sells for $399 and they claim that they have
525,710 users worldwide. That is just under $210 million. Obviously, not
all of XMLSpy's users paid retail. However, I suspect that their gross
is pretty good compared to the overall Ada market. XMLSpy, as of yet,
can not do XForms. The use of Ada should provide a significant
competitive advantage over C based languages.

Re: [OT] Switching to Linux (was: Microsoft takes on ACT)

[Pascal Obry]

I have seen a lot of time now reference to Ada, XML and GUI. You have claimed
that this will be the best way to build GUI with XSLT or Schema or XForms or
SVG. I know well most of these technologies and I fail to see any relation
here!

Please can you describe what you have in mind ?

- How Ada and XML are related ? For me they complement each others like coffee
  and Milk...

- How to build a GUI based on Ada + XML/XSLT ?

- Which kind of widget set will you use ? The one on the browser are just too
  simple for complexe applications.

I think that the list of technology is missing JavaScript. This is the way to
have dynamic on the client side... Ada is nowhere to play a role here... Ada
is good on the server side and middleware...

So again where do you see Ada on this ?

And no I have not yet read your article :), if the answers are there please
send it to me, thanks.

Pascal.

It's a reprint, only before it's published instead of after.

Publishing Jargon was RE: [OT] Switching to Linux (was: Microsoft takes on ACT)

[Robert C. Leif]

From: Bob Leif
To: Chris Danx et al.

Actually, it is not anyone's stupidity but my use of scientific jargon.
A preprint is a copy of a paper prior to its publication. It has the
virtue that the author still owns the copyright. A reprint is a copy of
the paper made after publication. Reprints are often printed copies of
the papers, which are sold by the publishers to the authors. They were
an excellent business for publishers. 

Parenthetically, there is another relevant term, disintermediation. This
means eliminating the publisher entirely, usually by publishing the
material on the web.

Recently I've wondering if there are companies or organisations that let the
author retain copyright of his/her work and at the same time publish printed
copies of their work.  Like say someone wrote a book, and wanted to retain
copyright but allow a company to sell printed copies in a contractual
agreement (with provisions for change of owner of copyright, like the author
approaching another company to publish it, and handing copyright to them).
Just something that's been floating around upstairs for a while.

Springer-Verlag publishes a printed copy of the Ada RM, but the
copyright is held by the U.S. government, with a very liberal
copyright notice (which I wrote, by the way -- although I had to
pass it through some lawyers).
