Please visit the [SQLite & TCL conference](https://conf.tcl-lang.org/) home page to stay informed.

# Call for Speakers

We've made it easier to contribute by asking for shorter, less formal
talks rather than requiring formal papers.

  - Have you done interesting work that you would like to share?

  - How about a cool idea that's not yet baked or just in the
    prototype stage but seems like something others would be
    interested in? We are particularly interested in new ideas, to
    hear about novel solutions to problems you've faced, or to see
    your work in progress.

## To submit your talk:

Please visit the [call for speakers page](https://conf.tcl-lang.org/callforspeakers/)
for instructions.

As a token of our appreciation, each speaker will be gifted with a
video conferencing light kit to use while presenting.

[ASCEND] Call For Presentations - SQLite & Tcl 2020 (Virtual Event)

[<con...@tc...>]

Hello ascend-sim-users, fyi ...

SQLite & Tcl 2020 (Virtual Event)
https://www.tcl-lang.org/community/tcl2020/

This year the Tcl conference of past years has been re-imaged as a
virtual event titled __S&T 2020 (SQLite & TCL)__, to be held
__Tuesday, November 10 from 10am to 3pm CDT__. The exact timing is
subject to change depending on the amount of people who sign up to
present a WIP (work in progress) presentation.

The event will be hosted through Zoom.
To register please go to the
[event details on eventbrite](https://www.eventbrite.com/e/st-2020-tickets-122293825123).

Given the Covid-19 virus and all the disruption it's causing, we
thought rather than requiring people to put all the work and time into
creating a full-fledged academic paper, we'd instead make it easier on
contributors by asking for shorter, less formal talks.

Have you done interesting work that you would like to share?

How about a cool idea that's not yet baked or just in the prototype
stage but seems like something others would be interested in?

The SQLite & TCL audience would like to hear about it, and can provide
valuable discussion and feedback. We are particularly interested in
new ideas, to hear about novel solutions to problems you've faced, or
to see your work in progress.

To schedule your talk, please send email to
[vio...@fl...](mailto:vio...@fl...)

Sincerly.

Re: [ASCEND] Data Reader Efficient Use

[John P. <joh...@an...>]

Hi Andrew

Thanks for your question about ASCEND and the scalability of its data reader (DR) functionality. I wrote the original code there, and it was later expanded by José Zapata to add support for improved spline methods and additional data formats. The documentation, such as it is, is mostly in our wiki, here: https://ascend4.org/Data_reader.

You are proposing a really nice idea which is to share the in-memory instances of the data tables that the DR uses, to save memory. I think it's a very good idea.

As noted in the documentation, the DR uses the 'external relation' interface in ASCEND. This means that the datareader.c code has to work within the constraints of that API (https://ascend4.org/Writing_ASCEND_external_relations_in_C). That should be fine though; we get to implement a 'prepare' and a 'calculate' function for each external relation, and hence for each DR instance. When writing a DR extrel, the user gives details on the file format they want to use, the specific data file they want to load, as well as the columns they want to interpolate, using a 'data instance' such as that 'drconf' model mentioned in the Data Reader wiki page. 'datareader.c' handles the interfacing of the Data Reader with the user's ASCEND code.

The actual loading of the files is coordinated through dr.c (and dr.h). The file format (datareader_set_format) is used to set up links to the relevant file-format-specific routines that load the header and data rows from the data file in an abstracted way.

So by the time we're talking about a specific kind of datafile, the key stuff is happening eg in csv.c (http://code.ascend4.org/ascend/trunk/models/johnpye/datareader/csv.c?revision=3291&view=markup). csv.c loads the raw data from a CSV file and stores everything in the 'data' field of the DataReader struct. That is the key part where some re-use might be possible. It looks to me that the CSV file loads all of the columns from the file, even if only a part of it is actually requested by the user. That's actually nice -- it means we can reuse the resulting 'data' pointer across multiple DR instances.

If you were keen to implement an improvement here, I would say that a good option would be to modify the dr.c code so that when a request comes in to load a file of a given format, you first check a list of previously-loaded files and formats (eg g_datareader_files?). If the file has already been loaded and with the same format specifier, copy the 'data' pointer into the current DataReader struct, increment a reference, and go from there. If the file has not been loaded, load it and add it to the list. Then there would need to be some destructor code need, perhaps in ascend/compiler/simlist.c.

Another point on the scalability of the DR is that it uses linear search to position within the file. The idea there was that our typical use-case was time-stepping through a weather file, eg hourly throughout a year. However, in other uses, it might be desirable to be able to jump around more efficiently. In that case, there could be a binary search tree structure implemented for faster access to the data. Depending on whether you are using large data files, that might or might not be important.

If, on the other hand, you are looking for a different approach to this, you might like to look at the FPROPS code in ASCEND. This specifically implements fluid property data such as thermal conductivity, and reuses the data structures automatically. In that case, you could implement your own fluid data type (some recent work I did with ASCEND was in the 'fprops-incomp' branch, for modelling properties of incompressible fluids) http://code.ascend4.org/ascend/branches/fprops-incomp/models/johnpye/fprops/. You could look into that and see if it gives you an easier way forward. It has the advantage of making your same evaluation routines also accessible from Python, if that's of interest.

Hope this helps!

Cheers
JP

Hello,

    I am fairly new to ASCEND, and I have just discovered the Data Reader external library function, which seems a good fit for my application.  I would like to use Data Reader to interpolate tabulated data from a CSV file with two columns: temperature [K] and thermal conductivity integral [W/m].  I have achieved the desired results so far by creating a separate data reader object for each temperature variable.  For instance, if I divide my part of interest into four segments, then I declare four temperature variables and create four data readers to access the same CSV file to return the thermal conductivity for each of the four segments.  Upon loading the model, I get four solver messages that basically say "Created data reader at Memory Location" and "Read ### Lines".  So it appears that each data reader I create reads in all the information from the CSV file.
    Now I would like to discretize my part of interest into many more segments (hundreds possibly).  Using my current method, I will need to create hundreds of data readers that all read in the same exact information.  Is it possible to create a single data reader that can be accessed by multiple temperature variables to return the corresponding interpolated thermal conductivity integral?

Thank you,
Andrew Stubblefield

Submission of Summaries

Tcl/Tk 2019 will be held in Houston, Texas, USA from November 04, 2019 to November 08, 2019.

The program committee is asking for papers and presentation proposals
from anyone using or developing with Tcl/Tk (and extensions). Past
conferences (Proceedings: https://www.tcl-lang.org/community/conferences.html)
have seen submissions covering a wide variety of topics including:

* Scientific and engineering applications
* Industrial controls
* Distributed applications and Network Managment
* Object oriented extensions to Tcl/Tk
* New widgets for Tk
* Simulation and application steering with Tcl/Tk
* Tcl/Tk-centric operating environments
* Tcl/Tk on small and embedded devices
* Medical applications and visualization
* Use of different programming paradigms in Tcl/Tk and proposals for new
  directions.
* New areas of exploration for the Tcl/Tk language

Submissions should consist of an abstract of about 100 words and a
summary of not more than two pages, and should be sent as plain text
to tcl...@go... no later than September 09, 2019. Authors of accepted
abstracts will have until October 14, 2019 to submit their final
paper for the inclusion in the conference proceedings. The proceedings
will be made available on digital media, so extra materials such as
presentation slides, code examples, code for extensions etc. are
encouraged.

Printed proceedings will be produced as an on-demand book at lulu.com
Online proceedings will appear via
	https://www.tcl-lang.org/community/conferences.html

The authors will have 30 minutes to present their paper at
the conference.

The program committee will review and evaluate papers according to the
following criteria:

* Quantity and quality of novel content
* Relevance and interest to the Tcl/Tk community
* Suitability of content for presentation at the conference

Proposals may report on commercial or non-commercial systems, but
those with only blatant marketing content will not be accepted.

Application and experience papers need to strike a balance between
background on the application domain and the relevance of Tcl/Tk to
the application. Application and experience papers should clearly
explain how the application or experience illustrates a novel use of
Tcl/Tk, and what lessons the Tcl/Tk community can derive from the
application or experience to apply to their own development efforts.

Papers accompanied by non-disclosure agreements will be returned to
the author(s) unread. All submissions are held in the highest
confidentiality prior to publication in the Proceedings, both as a
matter of policy and in accord with the U. S. Copyright Act of 1976.

The primary author for each accepted paper will receive registration
to the Technical Sessions portion of the conference at a reduced rate.

Other Forms of Participation

The program committee also welcomes proposals for panel discussions of
up to 90 minutes. Proposals should include a list of confirmed
panelists, a title and format, and a panel description with position
statements from each panelist. Panels should have no more than four
speakers, including the panel moderator, and should allow time for
substantial interaction with attendees. Panels are not presentations
of related research papers.

Slots for Works-in-Progress (WIP) presentations and Birds-of-a-Feather
sessions (BOFs) are available on a first-come, first-served basis
starting in August 12, 2019. Specific instructions for reserving WIP
and BOF time slots will be provided in the registration information
available in August 12, 2019. Some WIP and BOF time slots will be held open
for on-site reservation. All attendees with an interesting work in
progress should consider reserving a WIP slot.

Re: [ASCEND] Ascend-sim-users Digest, Vol 50, Issue 1

[<mar...@di...>]

Hi John,
thanks for your mail. I just went the Tkinter route because I was 
interested in how the whole tcl based GUI works. It was an easy way for 
me to try it out.

I'm interested in tcl because I make music in my spare time with Pure 
data which has also a tcl based GUI.

https://en.wikipedia.org/wiki/Pure_Data

https://github.com/pure-data/pure-data


Pure Data also has a plugin to call external Python scripts:

https://github.com/grrrr/py


So I'm just experimenting a bit, learning tcl and how both ascend and 
pure data work in regard to their tcl interfaces.
And maybe I will some day in the future be able to spin out a general 
interface for both ascend and pure data.
There are some articles I've found where one could also think of doing 
this with PyGObject:

https://www.tcl.tk/community/tcl2017/assets/talk85/Paper.pdf

https://jefftrull.github.io/eda/qt/tcl/eventloop/2012/05/25/integrating-qt-tcl-event-loops.html

https://pygobject.readthedocs.io/en/latest/guide/threading.html


It's also just a little side project where I can learn how ascend worked 
back then when the Carnegie Mellon folks were working on it. I feel a 
bit like a software archaeologist when diving into the tcl code which is 
quite fun. ;)

Right now I'm stuck with "couldn't find procedure Color_Init". And I 
can't find it myself in which file this procedure ought to be.

Searching through the whole trunk branch gave no results: $ grep -Ril 
Color_Init *


Cheers,
mark

Re: [ASCEND] Check out the oldschool ASCEND tcl/tk interface with TkInter

[John P. <joh...@an...>]

Hi Mark

Apologies for the delay in my reply. I 'recently' removed that 
interval.c stuff from trunk as part of my attempt to clean up libascend 
and increase the test suite coverage, forgetting that it was used in the 
Tcl/Tk GUI. However rather than deleting the files, I moved them to the 
'disused/compiler' folder. I should perhaps copy them back from there 
back into trunk/ascend/compiler in order to preserve file history.

http://code.ascend4.org/ascend?view=revision&revision=3408

Regarding the Tcl/Tk GUI, that GUI still compiles/runs in trunk using 
regular Tcl/Tk (not TkInter), when building with SCons. Did you try that 
route? The starting point is the script tcltk/asc4dev, which will be 
built by SCons if all required dependencies are met.

It's very interesting that you were able to run the GUI via Python and 
TkInter, but I am wondering what you feel would be the benefit would be 
of maintaining such an approach, as opposed to the Python-free Tcl/Tk 
GUI that is currently built (although rarely testing, I have to admit, 
as evidenced by the missing interval.c file that you noticed).

Cheers
JP

[ASCEND] Check out the oldschool ASCEND tcl/tk interface with TkInter

[<mar...@di...>]

Dear all,
I found some time and wrapped the legacy tcl code with TkInter to relive 
the old ASCEND interface.

I made a wiki page for this:
http://ascend4.org/TkInter_wrapper_for_tcl/tk_GUI

There was an issue with tktable which I couldn't fix and also found this 
bug report which might actually not be resolved:
http://bugs.ascend4.org/view.php?id=254
see also: https://github.com/nbro/tktable/issues/3


Also the trunk branch was missing the interval.c and interval.h files in 
ascend/compiler/.
I copied the files over from the Python3 branch and then the issue was 
solved

In line 138 in solver.tcl the - bitmap {feet} and -bitmap{stop} options 
couldn't find the bitmaps in ascend/tcltk/tk/bitmaps.


Cheers,
mark

Submission of Summaries

Tcl/Tk 2018 will be held in Houston, Texas, USA from October 15, 2018 to October 19, 2018.

The program committee is asking for papers and presentation proposals
from anyone using or developing with Tcl/Tk (and extensions). Past
conferences (Proceedings: http://www.tcl.tk/community/conferences.html)
have seen submissions covering a wide variety of topics including:

* Scientific and engineering applications
* Industrial controls
* Distributed applications and Network Managment
* Object oriented extensions to Tcl/Tk
* New widgets for Tk
* Simulation and application steering with Tcl/Tk
* Tcl/Tk-centric operating environments
* Tcl/Tk on small and embedded devices
* Medical applications and visualization
* Use of different programming paradigms in Tcl/Tk and proposals for new
  directions.
* New areas of exploration for the Tcl/Tk language

Submissions should consist of an abstract of about 100 words and a
summary of not more than two pages, and should be sent as plain text
to tcl...@go... no later than August 20, 2018. Authors of accepted
abstracts will have until September 24, 2018 to submit their final
paper for the inclusion in the conference proceedings. The proceedings
will be made available on digital media, so extra materials such as
presentation slides, code examples, code for extensions etc. are
encouraged.

Printed proceedings will be produced as an on-demand book at lulu.com
Online proceedings will appear via
	http://www.tcl.tk/community/conferences.html

The authors will have 30 minutes to present their paper at
the conference.

The program committee will review and evaluate papers according to the
following criteria:

* Quantity and quality of novel content
* Relevance and interest to the Tcl/Tk community
* Suitability of content for presentation at the conference

Proposals may report on commercial or non-commercial systems, but
those with only blatant marketing content will not be accepted.

Application and experience papers need to strike a balance between
background on the application domain and the relevance of Tcl/Tk to
the application. Application and experience papers should clearly
explain how the application or experience illustrates a novel use of
Tcl/Tk, and what lessons the Tcl/Tk community can derive from the
application or experience to apply to their own development efforts.

Papers accompanied by non-disclosure agreements will be returned to
the author(s) unread. All submissions are held in the highest
confidentiality prior to publication in the Proceedings, both as a
matter of policy and in accord with the U. S. Copyright Act of 1976.

The primary author for each accepted paper will receive registration
to the Technical Sessions portion of the conference at a reduced rate.

Other Forms of Participation

The program committee also welcomes proposals for panel discussions of
up to 90 minutes. Proposals should include a list of confirmed
panelists, a title and format, and a panel description with position
statements from each panelist. Panels should have no more than four
speakers, including the panel moderator, and should allow time for
substantial interaction with attendees. Panels are not presentations
of related research papers.

Slots for Works-in-Progress (WIP) presentations and Birds-of-a-Feather
sessions (BOFs) are available on a first-come, first-served basis
starting in July 23, 2018. Specific instructions for reserving WIP
and BOF time slots will be provided in the registration information
available in July 23, 2018. Some WIP and BOF time slots will be held open
for on-site reservation. All attendees with an interesting work in
progress should consider reserving a WIP slot.

[ASCEND] help to contribute Re: Ascend-sim-users Digest, Vol 44, Issue 1

[<mar...@di...>]

Hi Arpit and everyone,
how about trying to implement the UNIFAC and PSRK models to Ascend?:
http://ascend4.org/Predictive_Soave-Redlich-Kwong_(PSRK)
http://ascend4.org/Modified_UNIFAC_(Dortmund)

I have a Python script for the modified UNIFAC model which I can send to 
you.

But the first step would be to store all the needed parameters. To quote 
John from Ascend-sim-users Digest, Vol 34, Issue 1 
(https://sourceforge.net/p/ascend-sim/mailman/message/34712639/):

"You may have noticed the 'helmholtz_prepare' and 'pengrob_prepare'
functions. These are for converting the 'filedata' datastructures
(which could in principle be stored in data files rather than C
structs_ and the 'rundata' data structures. These data structures are
deliberately separated by design, so that pre-calculation can be done
if needed. This is what we have done recently with the TTSE code
(which is 90% complete, still needs some tweaks, it's in Sidharth's
branch)."

Take a look at 
http://code.ascend4.org/ascend/branches/sid/models/johnpye/fprops/helmholtz.c?diff_format=h&revision=2982&view=markup&pathrev=2982
and at http://ascend4.org/User:Sidharth

So it would actually be nice to find a general way to store data for 
Ascend, be it as a SQLite database or XML data files with a graphical 
interface for users to add data. Quote from John:

"Regarding the properties database, I should mention that Richard Towers
did a bit of work on implementing XML storage for fluid properties. We
didn't complete the integration work, but there's some interesting stuff
there, including the ability to render the XML to HTML using XSD, for
easy human-readable checking/review of correlation data that has been
entered. Some kind of editable data file is good for people wanting to
add new species, but at the same time, it adds some parsing overhead to
the codebase compared to the current approach of declaring C99 data
structures."

See: http://ascend4.org/User:RichardTowers

So either just convert all the data from appendix B in the following 
publication to C data structs: 
http://dx.doi.org/10.1016/j.fluid.2004.11.002

or try to go for a more elaborate way of storing the data as described 
above.

When the whole database system is set up one could start implementing 
linear algebra routines for property calculations which are needed for 
e.g. UNIFAC and PSRK. ASCEND only has code covering the matrix routines 
needed for solving the system of equations of the model a user has 
implemented:

"I don't think that reusing the ASCEND matrix routines is the 
necessarily
the way to go for property calcs."

So basically convert the Python script I then will send you to C and 
access the database and perform the matrix inversion and matrix 
multiplication with LAPACK/CBLAS.

And finally embed the routine in ASCEND so that users can call 
UNIFAC/PSRK within ASCEND.


Hope this was of any help or inspiration. ;)

Cheers,
mark

Submission of Summaries

Tcl/Tk 2017 will be held in Houston, Texas, USA from October 16, 2017 to October 20, 2017.

The program committee is asking for papers and presentation proposals
from anyone using or developing with Tcl/Tk (and extensions). Past
conferences have seen submissions covering a wide variety of topics
including:

* Scientific and engineering applications
* Industrial controls
* Distributed applications and Network Managment
* Object oriented extensions to Tcl/Tk
* New widgets for Tk
* Simulation and application steering with Tcl/Tk
* Tcl/Tk-centric operating environments
* Tcl/Tk on small and embedded devices
* Medical applications and visualization
* Use of different programming paradigms in Tcl/Tk and proposals for new
  directions.
* New areas of exploration for the Tcl/Tk language

Submissions should consist of an abstract of about 100 words and a
summary of not more than two pages, and should be sent as plain text
to tcl...@go... no later than August 21, 2017. Authors of accepted
abstracts will have until September 25, 2017 to submit their final
paper for the inclusion in the conference proceedings. The proceedings
will be made available on digital media, so extra materials such as
presentation slides, code examples, code for extensions etc. are
encouraged.

Printed proceedings will be produced as an on-demand book at lulu.com

The authors will have 30 minutes to present their paper at
the conference.

The program committee will review and evaluate papers according to the
following criteria:

* Quantity and quality of novel content
* Relevance and interest to the Tcl/Tk community
* Suitability of content for presentation at the conference

Proposals may report on commercial or non-commercial systems, but
those with only blatant marketing content will not be accepted.

Application and experience papers need to strike a balance between
background on the application domain and the relevance of Tcl/Tk to
the application. Application and experience papers should clearly
explain how the application or experience illustrates a novel use of
Tcl/Tk, and what lessons the Tcl/Tk community can derive from the
application or experience to apply to their own development efforts.

Papers accompanied by non-disclosure agreements will be returned to
the author(s) unread. All submissions are held in the highest
confidentiality prior to publication in the Proceedings, both as a
matter of policy and in accord with the U. S. Copyright Act of 1976.

The primary author for each accepted paper will receive registration
to the Technical Sessions portion of the conference at a reduced rate.

Other Forms of Participation

The program committee also welcomes proposals for panel discussions of
up to 90 minutes. Proposals should include a list of confirmed
panelists, a title and format, and a panel description with position
statements from each panelist. Panels should have no more than four
speakers, including the panel moderator, and should allow time for
substantial interaction with attendees. Panels are not presentations
of related research papers.

Slots for Works-in-Progress (WIP) presentations and Birds-of-a-Feather
sessions (BOFs) are available on a first-come, first-served basis
starting in July 24, 2017. Specific instructions for reserving WIP
and BOF time slots will be provided in the registration information
available in July 24, 2017. Some WIP and BOF time slots will be held open
for on-site reservation. All attendees with an interesting work in
progress should consider reserving a WIP slot.
