[jos-general] JOS is back!!

[Stefan R. <ste...@go...>]

Hey folks.

I'm one of the core developers of the original JOS project.

I'm doing it again.

This time it's real. Computers have advanced, Java native libraries have
advanced (we can now embed Chrome and VLC into Java windows), Java has
advanced (I made a dialect of it with important improvements called
"JavaX"), and the JVM has advanced into stability & speed.

Also, Microsoft is strongly out of favor these days, so it is TIME FOR A
NEW OPERATING SYSTEM!

My Java OS WORKS RIGHT NOW as a guest inside Windows, Linux or Mac OS.

Testers & devs wanted NOW!!

All the best,
Stefan

Re: [jos-general] is JOS dead?

[Gilbert H. <gc...@mi...>]

Dear Denny,

Thank you for expressing an interest in JOS, a Java-based operating system. You're asking the same question that has been asked since the project was established in 1997. Every so often, someone would ask this question. Surprisingly, we would get a wide variety of opinions about what the right answer should be.

In 1997, the JOS Project was way ahead of its time. The software industry hadn't yet produced and established any of the standard APIs an operating system would need, such as OSGi and JAF, EL and JNDI, Pack200 and Isolate, and even java.io.Console. We proposed a Console interface in 1997!

The industry hadn't yet matured to the point where programming languages other than "Java" were accepted to run on an off-the-shelf JVM, such as Groovy and Scala, Jython and Ceylon. We embraced from the very beginning that non-Java programming languages can be used along side Java in a Java-based operating system.

As you may have heard from Avery Regier, the project *never* produced working code. Avery points to the fact that we never had a widely successful Java-based kernel officially called "JOS" and adopted as the official Java-based operating system. He's right. We've never had a successful pure Java-based kernel. We might point to the fact that we could never agree on which architecture had the best chance of commercial and technical success. In fact, we've never had a consensus about how to go about building the best Java-based anything.

I have a very different opinion. The JOS Project produced working code. I can point to JEPS, Amairgin HTTP server, JJOS, kissme, teaseme and, even as Avery points out, JNode. One of the most widely known Java-based operating systems is called Android. But there are others, like JIKES OS. There was two from Sun Microsystems, one called JavaOS.

I have been actively contributing to the JOS Project from 1997 thru 2013. So, forgive me for being a little annoyed and concerned when someone says that it's dead.

Why is JOS dead? The project is dead because everyone believes that it is dead. Everyone believes that its dead because there is little effort put into maintaining the super-project web site. Everyone believes that it is dead because there is no new release of working code. No new release is planned.

In 1997, JOS was a difficult, if not impossible, ambitious and forward-looking project. We enthusiastically agreed that an operating system could be built from Java technology, and should be. This fact has never changed. I believe this more today than I did in 1997.

1. Android. This is a commercially successful Java-based operating system. It uses the Transitional Architecture because it uses a modified Linux kernel and low-level device drivers written in C/C++. It is not quite the pure Ultimate Architecture that we would have liked. We strongly recommended a package loader, a package-oriented class loader, instead of a class loader to many reasons, such as saving memory at runtime. Android adopts this strategy. As we predicted, Android developers continue to struggle with the mixed model that combines C/C++ and Java programming languages.

2. JNode. This is an experimental, proof-of-concept project for a Java-based operating system. It uses the Ultimate Architecture. The Java Virtual Machine/Kernel is written in the Java programming language. Unfortunately, it suffers from a non-modular and non-preemptive multitasking internal model.

3. JJOS. This is an experimental, proof-of-concept project for a Java-based operating system. It doesn't quite use the Ultimate Architecture. The Java Virtual Machine/Kernel is written in C/C++. It suffers from non-preemptive multitasking internal model. And yet, it proves that device drivers can be written in the Java programming language.

4. CjOS. We're currently migrating from a very large monolithic Java class library to OSGi. Today, you can run CjOS inside any OSGi container, such as Equinox, Eclipse, IBM WebSphere Application Server. Of course, this is my favorite project. It is following the strategy of Linux. Development of Linux tool almost two decades. The last piece added to Linux was a kernel. The last thing we're adding to CjOS is a kernel.

JOS is dead. And yet, its research still stands. It's still true and relevant. It should be the first thing to study before trying to build a Java-based operating system of your own.

Thanks again,

Re: [jos-general] is JOS dead?

[Regier A. J <Reg...@Jo...>]

Yes, JOS is dead. It really was stillborn, since it produced no working code. That's also the reason why it stopped. 

Jnode.org produced some working code and is the closest thing out there to an OSS Java OS. Or Android. Take your pick.

[jos-general] JOS Project: Changes to web site

[Gilbert C. H. II <gc...@mi...>]

Dear Members,

Please notice the changes to the public web site for the JOS Project.

1. Pages for the JOS Project are now maintained in the JOS CVS at 
sourceforge.net.

2. The default page for the project, http://jos.sourceforge.net/ , is 
the main page for the project--not the main page for the wiki. This 
page is no longer available at http://cjos.sourceforge.net/archive/ .

3. The Info section moved from 
http://cjos.sourceforge.net/archive/news/index.html to 
http://jos.sourceforge.net/news.html .

4. The constitution moved from 
http://cjos.sourceforge.net/archive/constitution.html to 
http://jos.sourceforge.net/constitution.html .

5. The policy book moved from 
http://cjos.sourceforge.net/archive/policybook.html to 
http://jos.sourceforge.net/policybook.html .

6. The DevZone section moved from 
http://cjos.sourceforge.net/archive/dev/index.html to 
http://jos.sourceforge.net/dev.html .

7. All of the JOS Wiki pages at http://jos.sourceforge.net/html/ have 
been updated. The header reflects the above changes.

Thanks,

[jos-general] New Java-based operating system from IBM

[Gilbert C. H. II <gc...@mi...>]

Dear Members,

IBM has just announced a new product called "WebSphere Application 
Server Hypervisor Edition". What is this exactly? They started with 
an off-the-shelf copy of Linux. They added enough code required for 
administration. They have removed all of the unnecessary native tools.

http://www-01.ibm.com/software/webservers/appserv/hypervisor/

All of this is packaged on virtual disks for deployment with VMware 
ESX. In this product, they added IBM JDK 5. They added WebSphere, 
their flagship application server. They optimized components to boost 
the performance of WebSphere. WebSphere is based upon OSGi, a module 
system for Java.

The administration "console" for the operating system is an 
off-the-shelf browser on a separate machine. The local console is a 
character based user interface. This reduces the complexity of the 
system, reduces the amount of disk space and memory required.

By definition, this is a "Transitional Java-based Operating System". 
Mostly, the product is built from existing components. A separate 
kernel project was not required. A separate JDK effort was not 
required. A separate WebSphere project was not required. A separate 
OSGi project was not required. A separate API effort was not required.

Do you think this goes far enough? Or, is there a real need for a 
Java-only operating system?

The following proposal for a "Transitional Java-based Operating 
System" was posted on this list in 1998. It went something like this:

1. Start with an off-the-shelf copy of the free license and open 
source Linux operating system.
2. Add Java programs, libraries, frameworks required for 
administration. Remember the policy that "everything that can be 
written in Java should be written in Java."
3. Remove all of the unnecessary native tools.

We were excited by the potential for such an operating system. We 
were excited about applying Java technologies to the operating system 
puzzle. From the first day, the JOS Project has been collaborating on 
a Java-based operating system. We have always agreed that our goal 
was worthwhile and important to the software industry.

I am not an employee of IBM. I am not a business partner. I am a 
software architect and technical writer.

Thanks,

Re: [jos-general] Dwonload link for JOS

[Gilbert C. H. II <gc...@mi...>]

As of January 2009, JOS is an incomplete specification for an 
operating system called Java Operating System. It recommends existing 
APIs where possible. Other parts of JOS are now available for 
immediate download.

Most of the JOS-related components can be downloaded and installed on 
any operating system. On the other hand, a kernel, such as JJOS, 
cannot run simultaneously on Linux, OS/X and Windows without virtual 
machine technology, such as VMWare Player.

[jos-general] WANTED: Testing the redirect mechanism.

[Gilbert C. H. II <gc...@mi...>]

Please test our website. Requests for JOS wiki pages should be 
redirected through the JOS Project website.

Let X be the name of any article (or topic) in the wiki.

An incoming request /view//X redirects to /html/X.html

We use .htaccess to instruct Apache HTTP Service to send a redirect 
back to the browser. Here is a copy of our .htaccess file.

----- .htaccess -----
RewriteEngine   On
RewriteBase     /

# RewriteRule  ^view/(.*)/(.*)$  view.php?topic=$2&web=$1  [L]
RewriteRule  ^view/(.*)$  http://jos.sourceforge.net/html/$1.html  [L]

Re: [jos-general] Removing a former member of the JOS Project

[Robert F. <ro...@27...>]

Hi Gilbert

I just added this person as a developer if he still needs it.  You are
correct though about the permanent nature of internet activity, it's
almost impossible to remove the traces.  I wouldn't add him as a admin,
I didn't even know I was one.  Eight years is a long time since working
on, and it's got to be a few years since I last looked at this mailing
list.

[jos-general] Removing a former member of the JOS Project

[Gilbert C. H. II <gc...@mi...>]

A former member of the JOS Project has requested to become an 
administrator of the JOS Project--in order to remove his personal 
information from HTML pages and Java source code. So far, I have done 
what I can to remove his personal information on his behalf.

It does not make sense to me to grant administrator access to someone 
who has left the project.

I am but one administrator of the JOS Project at sourceforge.net. I 
am not going to grant administrator privileges to another person, no 
matter how insistent they might be.

We have very limited capability to remove personal information from 
mailing list archives. We have no known capability of removing 
personal information from RPMs which have already been distributed. 
We "remove" information by publishing a new release of an RPM.

The jos-general list itself is archived. Everything sent to the list 
is a "permantent" record. How do we remove information that was 
unintended to be part of the mailing list archive? I do not know.

How should we handle this matter?

Thanks,

[jos-general] Restore JOS Wiki?

[Gilbert C. H. II <gc...@mi...>]

Attention administrators of the JOS Project:

Should we turn on the wiki service? Should we import articles from 
the original JOS Wiki? A wiki service is now offered at sourceforge.net.

A. It is possible to start with a clean wiki and include existing 
articles by reference.

B. It may be possible to convert the JOS Wiki from HTML to this wiki 
service. Once again, this would enable us to maintain articles 
contributed to the JOS Wiki.

Thanks to sourceforge.net for providing the infrastructure to develop 
a Java-based operating system! And thank you for your kind attention 
to this matter.

[jos-general] Release 1.0-33.5 of Release Frame is now availble.

[Gilbert C. H. II <gc...@mi...>]

"Release Frame" generates Ant scripts and RPM specifications. It is 
an x-framework, built upon XVCL Processor 
(http://fxvcl.sourceforge.net/) and XML Bind 
(http://cjos.sourceforge.net/html/CjosLibrary.html).

The XVCL Processor 2.07 (1h) is extended with the xmlproperty 
command. This command uses XML Bind to load and parse an XML document 
into a model, something borrowed from Christian Heller's book, 
"Cybernetics Oriented Programming (CYBOP) - An Investigation on the 
Applicability of Inter-Disciplinary Concepts" (Tux Tax). Many thanks 
Chrisian Heller!

The CjOS Project is switching to Release Frame for its upcoming 
release of CjOS 1.0-34.

Benefit. For the first time in a long time, I feel like I have caught 
up on my work. After designing and testing the Release Frame 
x-framework with the CjOS Project, I turned my attention to a much 
neglected project called RandDos. I saved much time and complexity by 
describing the jar to be distributed in distribution.xml and XVCL 
Processor writes all of the Ant scripts and RPM specifications for me.

How it works. The distribution.xml file contains the knowledge (what 
we want to release). The XVCL Processor uses an x-framework called 
"Release Frame" to read the distribution.xml document as a model and 
generate Ant scripts and RPM specifications. For each jar, there is a 
source edition, a binary edition, a no-source RPM and target RPMs 
(-ant, -javadoc and -websource).

In Karl Fogel's book, "Producing Open Source Software" (O'Reilly), he 
identifies the minimum requirements of a release. A product built by 
the "Release Frame" x-framework meets many of these requirements.

Thanks,

[jos-general] CjOS Release 1.0-33 is now available.

[Gilbert C. H. II <gc...@mi...>]

Release 1.0-33 of CjOS is now available for Linux/RPM. It is

invite your feedback.

Thanks,

[jos-general] Our code on your site

[Gilbert C. H. II <gc...@mi...>]

I am writing primarily because our code on your site is out-of-date. 
Could you please describe your update/refresh policy?

I am a maintainer on the CjOS Project at sourceforge.net. I am 
pleased to see that our open source code is available on your 
website. It seems that a snapshot of CjOS CVS was obtained in 2004. 
How often should our source code be refreshed? To be of value to the 
community, it seems reasonable to refresh more often than once every 
three years.

Your website could be an important resource for our project. With 
your cooperation in this matter, I would like to mention your site on 
our homepage.

I am also using the XML Varient Configuration Language (XVCL) from 
the FXVCL Project at sourceforge.net. Stanislaw Jarzabek and others 
maintain the FXVCL Project. In his book, "Effective Software 
Maintenance and Evolution - A Reuse-Based Approach", Stanislaw 
Jarzabek presents compelling evidence for the use of a query language 
for source code. A highly productive programmer needs a tool to query 
existing source code. He goes on to describe a product much like yours.

[jos-general] XVCL Processor 3.2.1 is available

[Gilbert C. H. II <gc...@mi...>]

XML Variant Configuration Language (XVCL) is equivalent to a general

HTML, JSP, XML, and more. It is maintained at http://fxvcl.sourceforge.net/
. Version 3.2.1 of the XVCL Processor is now available for download.

Currently, we use XVCL Processor 2.07 to generate Java source code for a
few packages of the CjOS Project. And we are evaluating XVCL Processor
3.2.1 for use with Apache Ant. We are also evaluating XVCL Workbench 3.2.1,
a plug-in for Eclipse 3.1 or higher.
