RE: [Mod-pubsub-developer] Win32 Subscribe Problem

[Tommy H. <th...@ch...>]

Hi Rand,

Are you sure that the python server is running on port 8000? What I see
is that the server is not properly returning a request ID or an empty
request ID. This is causing the failure.=20

What are the parameters you're passing to the pubsub.py server?

Also what platform are you using? Windows XP? Windows 2000?

When I run the subscribe.vbs script as per above, I get this:

Also, you can run

Cscript /mod_pubsub/cxx_pubsub/LibKN/Tests/wsh/subscribe.vbs
http://localhost:8080/kn /what/chat

To subscribe to the /what/chat topic. Then you can also use the chatlet
at

http://localhost:8080/js_pubsub/samples/chatlet/index.html=20

to publish a message to see it appear in the subscribe.vbs console
window.

What I'm having trouble with is the samples that are included in the
win32-kndesktop package.

So, under the LibKN\Samples folder, there are 4 folders of samples:
html, office, vb, and wsh. It is these for
which I can't get any examples of subscribing to work. (publishing works

Hi!

I got it to work with the sample in

/LibKN/Tests/cpp/SubTest (as the subscriber) and The Javascript chatlet
as the publisher

The important to know is that the SubTest sample requires two arguments:

	http://localhost:8080/kn /what/chat

This is assuming that the python server is running on port 8080. Now,
entering a message in the chatlet will show the message in the SubTest
program.

[Mod-pubsub-developer] Paper Airplane - a web server in a browser

[Asynch M. <asy...@ho...>]

Interesting...

===
http://www.paperairplane.us/
Paper Airplane is a Mozilla plugin that empowers people to easily create
collaborative communities, known as Paper Airplane Groups, without setting
up servers or spending money. It does this by integrating a web server into
the browser itself, including tools to create collaborative online
communities that are stored on the machine. Paper Airplane Groups are stored
locally on a user's machine. A peer-to-peer network is created between all
of the Paper Airplane nodes that are running in order to resolve group
names, reach normally unreachable peers due to firewalls or NAT devices, and
to replicate content.

Parts of Paper Airplane have been modularized into the P2P Sockets project,
a reimplementation of standard Java sockets on top of Jxta and ports of
standard web servers, servlet engines, etc. to run on top of a peer-to-peer
network. P2P Sockets is at a 1.0 beta level, while Paper Airplane
development is just beginning. Paper Airplane code will be posted to this
site as it is developed.

[Mod-pubsub-developer] clipit - project from coin-operated

[Asynch M. <asy...@ho...>]

http://www.mle.ie/~jonah/projects/clipit.html
Overview
ClipIt! Is a downloadable networked application that provides an ambient
connection to other people's desktops by distributing the contents of each
users clipboard. The project works as an automatic Post-It or sticky note
that is meant to allow people to catch a glimpse of the activity on other
people's machines.
Prototype
Copy and paste are ubiquitous elements of the modern computer GUI interface.
They are both infinitely useful for working with computers and are integral
elements to all computers across all platforms. Our use of these functions
is so natural that we even forget we use them and without them our methods
of computer interaction would change dramatically.

ClipIt! centers on this background activity of copy and paste. Specifically,
it looks at how we use, collect, distribute, and disseminate information.
Instead of using foreground applications like Instant Messengers and email,
where you have to actively connect to people, ClipIt! is deliberately
intended for background use. When multiple users are connected, their
clipboards are uploaded and shared with each other, thus providing an
ambient link and direct window into someone else's activities.

The project allows people to be aware of each other's computer usage and to
"get a feel" for what they are working on or thinking about in real-time.
ClipIt! follows in the footsteps of programs like Deskswap, an application
that allows you to share screenshots of desktops with other people, but is
more interested in sharing the low-bandwidth information of everyday
interaction.


System
The system works as a downloadable application for both Mac and PC that is
meant to run all day long in the background of your networked computer.
Users do not have to 'paste' anything to ClipIt!, they only have to copy
information as they would normally. The program loops through all of the
clipboards according to who logged in first and displays text and small
graphics that are copied.

[Mod-pubsub-developer] Interesting note about JS client work making cool web apps

[Asynch M. <asy...@ho...>]

http://www.windley.com/2004/04/06.html#a1154

"It would be impressive if CanyonBridge used Javascript to build a slick
Outlook replacement, but its how they did it that got me excited. First,
they have a technology for just sending snippets of pages back and forth
between the server and the browser so that the Web page doesn't have to be
refreshed. The Javascript modifies the display using the DOM in accordance
with instructions from the server
Second, they built a SOAP front-end for Exchange so that they can deal with
Exchange using SOAP calls rather than MAPI. Of course once that's done, you
could substitute something else for Exchange itself and that's just what
they've done. They've got a Linux/MySQL replacement for Exchange in Alpha
right now.

Thirdly, they build a server side orchestration language for controlling the
presentation and interacting with SOAP-based services so that the action of
the client is controlled using an XML-based business logic language.

Fourth, the Javascript that runs the Outlook replacement isn't custom
one-off code, but built using a framework. Consequently, you can program
things besides Outlook fairly easily.

To demonstrate the power of this, one of the demonstrations they showed me
was a Salesforce.com integration with their Outlook replacement. Not only
could you see all of your Exchange-based calendar, contact, and messaging in
the tool, you could also see all of your leads and appointments from
Salesforce.com. The calendar showed Exchange hosed appointments in an
integrated view with the Salesforce.com appointments. Very cool. What's
more, they built it in 3 days."

Yep!  We have a meeting room at AirWave.  We're at 1700 S. El Camino
Real, Suite 500, San Mateo, CA.  Directions: 

- by Caltrain: get off at Hayward Park.  Walk to the north end of the
  station, down the paved footpath to the street, then west until you cross
  El Camino.  We're in the blocky five-story building on the northwest
  corner, across from Washington Mutual.

- by car: we're a block north of highway 92 on El Camino Real.  92 is
  the San Mateo Bridge.  Plenty of parking behind the building.

The building doors lock at 18:00, so to ensure you can get in, (a)
email me at this address to let me know you're coming and (b) call me
when you get to the doors if you can't otherwise get in.  I'll wait
downstairs until about 18:40 to collect people for the first trip
upstairs.

We have plenty of whiteboards and network access, but food is usually
in short supply.  Anyone have any suggestions for ordering in?

As a bit of an aside (since everything you've said is completely true), 
while epoll(), /dev/poll and kqueue() are much more scalable than poll, 
you can still get pretty decent performance out of stock poll().  For 
instance, our MTA (ecelerity) can support 100,000 inbound connections 
at 450 messages per second, which is pretty darn fast (200-300 Mb/s).  
You get better performance out of the platform-specific event systems 
(and we support those on systems that support them), but the poll() 
performance is not shabby.

At any rate, even without it's implementation in twisted, porting to 
twisted seems to be the fastest way to get epoll() support, as it is 
likely to show up there soon and be well supported.

I have no doubt that poll() will do the job, but as to whether or not=20
poll() will induce high latency with a huge number of long-lived=20
clients, I'm not sure:

http://lse.sf.net/epoll/index.html#compare

Solaris added /dev/poll for many of the same reasons that Linux has=20
added epoll and FreeBSD kqueue/kevent. It's just another step in the=20
research-driven evolution of Unix in general. Select breaks down well=20
before poll when faced with lots of connnections, but with 10K active=20
clients, it's not unreasonable to expect even poll()'s O(changed FDs)=20
performance to get problematic.

Just fyi, the epoll backport to 2.4 is slightly flaky (will build 
products that exploit that target that patch).  Even without epoll, the 
poll reactor will give you the scalability you need.  Either way, 
adding an epoll reactor should not be terribly difficult though.

[BC S. <bsi...@in...>]

George, the approach you lay out seems like the right one. The scheduler
in there now is only a last-minute hack and should be replaced by a real
scheduling system (Twisted, for example) at the first opportunity.

That's correct. PyKqueue should build on OS X, but so far gcc 3.3 is=20
giving me fits (even after hacking the makefile a couple of times).=20
PyKqueue doesn't seem to have seen active maintenance since about=20
2000-2001, but is reported to still work.

As for doing the libevent reactor, the odds are very high that=20
libevent exposes sane semantics for what we need, and that writing a=20
reactor for it is the same effort (or lower) as writing an epoll=20
reactor. Whichever one Joyce chooses to go with is fine by me. Either=20
way we get coverage of all the OSes we need (collectively) need.

Regards.
