[Stackless] Invitation to Present at PyCon 2007

[Andrew Francis]

Hello Andrew and Colleagues:


> The deadline for submitting a talk for PyCon 2007,

>upon us.  

A year has pasted !!! October 31th is too tight.

>I don't know enough, yet, to be able to give a new
>talk.  At best it would be an intro talk describing
>what Stackless does and how to use it in different
>circumstances. 

>   - doing stackless I/O
>   - .. maybe something workflow related?

Well a large aspect of my Stackless Python WS-BPEL
processor ("Stagehand") involves both the logical
scheduling (read workflow) and network I/O. I
submitted a last minute talk to 2006 Vancouver Python
Conference but I couldn't get out there. 

Here is a slightly modified version of the abstract :

~

Stackless Python : Just Not for Gamers ....

WS-BPEL (web service business process execution
language) processors tackle many tough issues :
concurrency, transactions,  network programming,
persistence. Stagehand is a WS-BPEL implementation.
The enigmatic Stackless Python is used to implement an
important Stagehand component : the Processor (was the
scheduler).  

This talk will de-mystify Stackless Python by
illustrating how it is used to elegantly solve
problems from light weight concurrency to thread
synchronization to process persistence. Integration
with Twisted will also be discussed.

So far I have had success with Stackless and Twisted.
I still don't understand all the issues but I would be
happy to summarise the knowledge I gleaned from using
this mailing list.  I should put what I learnt in the
Wiki. Vis-a-vis WS-BPEL. It will be interesting when I
start incorporating WS-BPEL 2.0 changes.  This work
would probably begin in December once I finish the
processor.


Cheers,
Andrew
