Onward! 2011 -- Call for Papers, Essays, Films, and Workshops

Call for Papers, Essays, Films, and Workshops

-=-=-=-=-=

Onward! 2011
ACM Conference on New Ideas in Programming and Reflections on Software
October 22-27, 2011
Hilton Portland & Executive Tower, Portland, Oregon USA
Sponsored by ACM SIGPLAN

http://onward-conference.org/2011/
http://onward-conference.org/2011/poster.html

-=-=-=-=-=-=-=-=-=-=

Onward! is more radical, more visionary, and more open than other conferences to not (yet) so well-proven
but well-argued ideas. We welcome different ways of thinking about, approaching, and reporting on
programming language and software engineering research.

Onward! fosters the multidisciplinarity of software development. We are interested in anything to do
with programming and software. Processes, methods, languages, art, philosophy, biology, economics,
communities, politics, ethics, and of course applications. Anything!

Sounds good? Do you want to report on and present your new ideas to the community and get feedback? Do you have
a video to show or a story to tell, an essay perhaps? Do you want to bring reflections and new insights to the
community? Or do you simply want to know more about innovations, visions, and the future of programming
languages and software engineering? Then...

Join Onward!, the unique, creative, and collaborative environment to discuss and investigate
challenging problems related to software, its creation, and nurturing.

ScriptScheduler and ScriptProcesses under debug

I made a change to the squeak debugger so that stepping code
runs in the correct process. I'm now seeing Morphic freeze when
I step thru ScriptProcesses, but not normal processes. I have
some idea of why, but am not familiar enough with
ScriptScheduler to draw all the connections.

A phenomenon I feel has the same root cause is: When I proceed
from a halted ScriptProcess in the debugger (the unmodified
debugger), and the tweak window is minimized, it sometimes never
actually runs until I unminimize the tweak window. For instance,
if I restart a method with a halt in it then proceed, it should
nearly immediately hit the halt, but it never actually does so
until I un-minimize tweak

I can't figure out why either of these happen. I know
ScriptProcesses have some interaction with the ScriptScheduler
when they start and stop and wait on Semaphores (none of which I
really get the point of). However, ScriptProcess doesn't
override Process >> suspend or Process >> resume, but it almost
seems to be acting as if it did, and won't resume if the
ScriptScheduler is paused. 

Can anybody explain this?

PS: if you want a look at what I did to the debugger, get

Computers, networks, and other forms of technology are pervasive in our
information-based society.  Unfortunately, most users of this technology use it
for passive consumption of information and entertainment.  To evolve into a
true knowledge society it is critical that we transform computer-based human
activities to engage users in the active process of creating, connecting, and
collaborating together.

The C5 conference is for anyone interested in the use of computers as tools to
develop and enable user-oriented creation, connection, and collaboration
processes.  Researchers, developers, educators and users come together at C5 to
present new and ongoing work and to discuss future directions for creative
computing and multimedia environments.  We welcome the submission of
theoretical and technical papers, practitioner/experience reports, and papers
that bridge the gap between theory and practice or that encourage inter- and
cross-disciplinary study.

CFP: (Deadline Extension) S3 2010 Workshop on Self-sustaining Systems

*** Workshop on Self-sustaining Systems (S3) 2010 ***

September 27-28, 2010
The University of Tokyo, Japan
http://www.hpi.uni-potsdam.de/swa/s3/s3-10/

In cooperation with ACM SIGPLAN

=== Call for papers ===

The Workshop on Self-sustaining Systems (S3) is a forum for discussion 
of topics relating to computer systems and languages that are able to 
bootstrap, implement, modify, and maintain themselves. One property of 
these systems is that their implementation is based on small but 
powerful abstractions; examples include (amongst others) 
Squeak/Smalltalk, COLA, Klein/Self, PyPy/Python, Rubinius/Ruby, and 
Lisp. Such systems are the engines of their own replacement, giving 
researchers and developers great power to experiment with, and explore 
future directions from within, their own small language kernels.

S3 will be take place September 27-28, 2010 at The University of Tokyo, 
Japan. It is an exciting opportunity for researchers and practitioners 
interested in self-sustaining systems to meet and share their knowledge, 
experience, and ideas for future research and development.

--- Submissions and proceedings ---

S3 invites submissions of high-quality papers reporting original 
research, or describing innovative contributions to, or experience with, 
self-sustaining systems, their implementation, and their application. 
Papers that depart significantly from established ideas and practices 
are particularly welcome.

Submissions must not have been published previously and must not be 
under review for any another refereed event or publication. The program 
committee will evaluate each contributed paper based on its relevance, 
significance, clarity, and originality. Revised papers will be published 
as post-proceedings in the ACM Digital Library.

Papers should be submitted electronically via EasyChair at 
http://www.easychair.org/conferences/?conf=s32010 in PDF format. 
Submissions must be written in English (the official language of the 
workshop) and must not exceed 10 pages. They should use the ACM SIGPLAN 
10 point format, templates for which are available at 
http://www.acm.org/sigs/sigplan/authorInformation.htm.

how to use standalone teatime/tobjects?

Hey all, millimetering ever-closer to a squeak plugin to SL. The pattern 
is quite simple:

start second life.

add a texture to a prim in SL that points to a localhost server with 
appropriate mime type.

have a plugin present for SL that  can send a shared memory buffer to a 
cobalt instance.

render into that instance with appropriate channels for mouse/keyboard I/O.

Tada: Croquet/Cobalt on a prim.

The Teatime architecture appears to be the ultimate P2P plugin tester, 
but its only being used for the rather huge Croquet/Cobalt use-case.

Now, this is going to be fun, and possibly useful, but for most users of 
SL, Croquet isn't going to be all that attractive, at least at first. In 
order to get a foot in the door, I want to establish a TObject which 
renders to SL, accepts I/O from SL and broadcasts it to other TObjects 
connected to OTHER SL clients.

This turns squeak into a media plugin prototyper for SL AND opens the 
door for more interesting plugins, such as ones that generate 3D data 
(not necessarily in Croquet format) for injection into SL.

The same pattern could be added to any kind of chatroom. The ultimate 
form would be having a Croquet/Cobalt window embedded in an IRC or 
Google Wave window, but more limited object sharing should be quite 
useful (often more useful given the overhead of a complete Croquet world).

So, my question is: how do I strip TObjects/Teatime away from the rather 
huge Croquet context, so that I could do a hello world example of a 
simple TObject rendering to a SL media plugin and sending updates to 
other TObjects connected to other SL clients via the media plugin?

The sky is the limit for this functionality, IMHO. Croquet is only the 
sexiest example, but in fact, I don't think its the most practical. The 
hello world TObject is much easier to grasp the implications of, because 
"rendering" can be replaced with ANY object-state transfer to the target 
application (which could be anything, not just the Second Life client).
