Hi Stefano,

Sorry for the delayed response been away for a few days. Yep will be
very interesting to see how Sun commercializes the Savaje intellectual
property they purchased from the liquidated assets.

 

One of my clients www.Mexuar.com http://www.mexuar.com/  built a
number of applications for the Savaje launch in SF 2006 so we are
watching this recent announcement with anticipation. Will be an
interesting few months to say the least.

Moore's law continues to march on, only now instead of (super)-linear
speed-up on a single core, we're getting multiple cores.  Java will be
OK with 'multi-core', but won't survive the transition to 'manycore' (
100 cores), nor will Python, PHP or Perl.

This may not matter on a phone platform, but the desktop and server will
distance themselves from co-operating sequential processes before too
much longer.


I think you are saying that the thread model of concurrency has
limits, right?  Or just that programmers will balk at having to manage
hundreds of threads?  Well what do you think is the future then, to
get more parallelism?


The only question is if the rest of the industry 'woke up' enough to see
the light of cracking the phone wide-open.  If not, they are doomed.


Yeah that's a big one.  I think Apple's view is that their
applications are always best-of-breed anyway, and they can satisfy 90%
of the users' needs themselves, so why be open to having third-party
security holes, usability problems, bugs and so on, which will sully
the reputation of the phone.  But I also think a lot of the success of
the early Palms was the wide variety of extra software you could
install on them.  I doubt that Apple will really keep the iPhone
closed forever, but we'll see.  Nowadays it's not like it was in the

at least OpenMoko might be able to run Java games or something.

I think one unsolved problem, which has probably hampered Java a lot,
is the lack of a process model.  If a Java VM was pre-loaded, and all
of the Java applications could run in one VM, the overhead for each
one would be much less, right?  I know, I've heard the excuse... well,
the OS is caching files anyway, each class's instructions are only
being loaded once, and a separate VM increases security.  But if a
phone's top priority at bootup was to just to get all of the necessary
classes into memory as fast as possible, and get the VM running, get
the UI up and be ready to do the basic phone stuff (calls, phonebook
etc.) maybe it could be fast.  But Java has always been an adjuct.  On
the desktop, first you have all the overhead of the OS and its own UI,
and then there is Java.  Anytime I run a desktop Java app my reaction
is ugh, you can always recognize a Java app by the startup time, the
amount of memory it's taking up, and the paint idiosyncracies and the
way the UI looks.  And the installer typically put its own VM in place
along with the app.  So you will be running a different VM for every
app.  This is not a platform!  And the phones I have worked with are
just limited to one Java app at a time because they can't

2007-05-11 Thread Jim Thompson

Shawn,

I'm more than happy to engage and debate these points, but its likely 
off-topic (or at least not in scope) for the list (which is about 
openmoko and/or the community that surrounds openmoko).


Topics such as:
why is Java slow (and how to construct hw to make it go fast

concurrency models (threads or not)

programming of same, and

Java's lack of a process model

aren't related (much) to openmoko, so I suggest we take these off-line, 
unless 'the list' decides they would rather watch/join the discussion 
here.  (And yes, I agree that I contributed to the discussion going 
off-track.)


The topic of Apple being open or closed, especially as it relates to the 
iPhone, seems at least peripheral to the discussion here.


I think it likely to be mere months before some rudimentary linux kernel 
is running on the iPhone, and likley less than a year from then until 
some dedicated group of hackers make the OpenMoko environment run on the 
iPhone in much the same way that the Mac and the AppleTV, and even the 
iPod now run specialized linux kernels to 'enable' a degree of openness 
that Apple expressly did not plan.


If OpenMoko is found to be a better environment than (or for) the iPhone 
(as well as other phones)... success!.   If Sun's JavaFX Mobile, 
well... success!

system available via OEM license to carriers, content owners and 
consumer electronics manufacturers. JavaFX leverages the security and 
ubiquity of the Java platform and will support all content and 
applications currently available across the billions of Java 
technology-based devices in the world today. Sun today also previewed 
JavaFX Script, a new scripting language targeted at creative 
professionals, which will help to radically simplify the process of 
creating and distributing interactive content that spans all Java 
technology enabled platforms, from handsets to set tops, laptops to 
dashboards (see separate announcement). ***All JavaFX software, like all

2007-05-10 Thread Terrence Barr - Evangelist, Java Mobile Embedded

Shawn,

I have been very involved in this area at Sun now for a couple of
years. Let me add come comments:

Hardware accelerated Java is actually fairly common already, at
least in the Java ME space using ARM's Jazelle technology. It does
have some benefits in very constrained platforms but in general
advanced VMs with dynamic adaptive optimizations, compilation,
and improved garbage collection perform better than H/W acceleration
and at reasonable incremental cost (memory footprint, in particular).

I think what we are seeing here is a general trend in the IT industry
as general-purpose processors become more and more powerful they
displace dedicated hardware solutions because software solutions are
more flexible and lower cost. A notable exception, of course, is
graphics acelleration but Java implementations typically use those
when available.

Specifically to Sun's Java chips (picoJava/microJava): I worked on them
and the performance was quite good. But it is very hard, if not
impossible, to keep up with performance improvements of general
purpose processors together with the increasing amount of memory
available. That technology evolution relegates Java hardware
acceleration to niche status. Many companies have invested in Java
H/W acceleration and fell into that trap.

As for the comparison of JavaFX Mobile with the iPhone: Sure, at
first it looks like a me too play, but I think this applies to
the whole mobile industry. The iPhone was a major wake-up call to
the industry and so I think you will see many iPhone knock-offs
over the next 18 months simply because the iPhone is leading the
way.

However, JavaFX Mobile is distinctly different in that it will
be an open system (not closed as the iPhone) and will be part of
a multi-screen approach that delivers content across desktops,
TV, and mobile. Only Java currently has that market reach so Sun would
be ill-advised *not* to capitalize that.

Cheers,

Moore's law continues to march on, only now instead of (super)-linear 
speed-up on a single core, we're getting multiple cores.  Java will be 
OK with 'multi-core', but won't survive the transition to 'manycore' ( 
100 cores), nor will Python, PHP or Perl.


This may not matter on a phone platform, but the desktop and server will 
distance themselves from co-operating sequential processes before too 
much longer.



As for the comparison of JavaFX Mobile with the iPhone: Sure, at
first it looks like a me too play, but I think this applies to
the whole mobile industry. The iPhone was a major wake-up call to
the industry and so I think you will see many iPhone knock-offs
over the next 18 months simply because the iPhone is leading the
way.


The only question is if the rest of the industry 'woke up' enough to see 
the light of cracking the phone wide-open.  If not, they are doomed. 
Bill Joy explained it a long time ago.


Lemma 1: # smart employees = log(# of employees)
-- there are more smart people outside your organization than inside it

Lemma 2: Innovation will occur
Lemma 1 tells us that it will occur elsewhere.

Question: How do you take advantage of innovation that occurs outside 
the organization?


Answer: Open Source

Of course, FOSS is one answer, there are others, but stating the answer 
without knowing the question is Jeopardy!



However, JavaFX Mobile is distinctly different in that it will
be an open system (not closed as the iPhone) and will be part of
a multi-screen approach that delivers content across desktops,
TV, and mobile. Only Java currently has that market reach so Sun would
be ill-advised *not* to capitalize that.


Even then, Java, even JavaFX is not the web.

 Hi

 I've  just read this

  WTF it's a Neo

Now that's funny... But as the text says:

even as he released a photo of a mockup (left)

And:

We're not introducing a phone. We're introducing software to make this
possible.

So I suppose they just made a screenshot of the software and pasted it onto
a picture of the Neo1973...


Nice! As it said here[1] it is real:
What is it?
It's a phone running Sun's new JavaFX Mobile software, a member of the
JavaFX product family we announced this morning

That's correct. This is going to be very cool stuff. And the Neo is
definitely very high on the list of devices I want to see this running
on.
