I don't know.  Looks like core Racket is now LGPLv3, which is pretty 
flexible about commercial uses.  I've been using LGPLv3 for almost all 
of my Racket packages since around 2009, and LGPLv2-something before 
that.  (One exception is that a financial data scraping package of mine 
is GPL, and I also was working on a Racket firmware that was GPL.)  The 
legal notice in the documentation of each of my packages says people can 
contact me about alternative licenses.  In the last 13 years, I recall 
only once someone asking about the license for one of my Racket/Scheme 
packages, and it turned out the person was fine with LGPLv3.

[racket-users] Appropriate open source license for a Racket based framework

2016-03-01 Thread Brian Adkins
I've finally begun a project to create a web framework for Racket. Are there 
any particular license issues that I should be aware of in this regard?

The MIT License is used by both Rails and Phoenix, and I've used it for other 
side projects, so I'm inclined to use it for this new framework unless there 
are good reasons not to with respect to interoperating with Racket and various 
Racket packages.

Thanks,
Brian

Re: [racket-users] Racket 6.4 very slow

Something is wrong with your installation. 6.4 is in the same ball park as 6.1 
Can you share the code that runs 20x slower? Thanks — Matthias

`htmlprag` was replaced by `html-parsing` and `html-writing` on

If the code using `htmlprag` is just using parsing and/or writing 
functionality from `htmlprag`, then the changes to that code are 
probably very simple.  Specifically, probably just needs the name a 
procedure changed, and maybe the calling signature has changed slightly..


If that doesn't immediately work, see the History sections of the 
package documentation:

If there's a significant problem, let me know.

It generally means the "other side" has closed the connection before
reading everything you sent.

I see it with clients using XHR, but I don't know what is the actual
issue because I don't do the client side programming.   It doesn't
happen often, but when it does it is due to a bug in the client code.

My racket server speaks only JSON.  It hides behind Apache which
provides static HTML service and redirects "function" URIs to my
server.

If you are seeing connections dropping in a different situation then I
have no clue.

>Is this just "Stuff happens, move on" or is it "Hm, should only happen once
>every hour, rather than once every 2 minutes"?

IME, _this_ error has always been due to bugs on the client side.

YMMV,
George

I'm pretty sure this is in the "stuff happens, move on" category. The
error happens when a client abandons a connection, for example, and you
should expect all sorts of communication interruptions.

[racket-users] Web server tcp-read: error reading (errno=104), connection reset by peer

2016-03-01 Thread Marc Kaufmann
Hi,

I am running a live server now, rather than local, and it keeps logging
this error message:

tcp-read: error reading
  system error: Connection reset by peer; errno=104

I have no idea what this means other than finding out on StackOverflow that
the error means someone somewhere has shut the connection. Is it another
server that is doing so, or is it the racket web-server? Is this just
"Stuff happens, move on" or is it "Hm, should only happen once every hour,
rather than once every 2 minutes"?

I should note that the website works fine, but I don't feel like ignoring
this and crossing my fingers.

Thanks,
Marc

[racket-users] [TFP 2016] 2nd call for papers

2016-03-01 Thread Peter Achten

 TFP 2016 ===

  17th Symposium on Trends in Functional Programming
   June 8-10, 2016
 University of Maryland, College Park
 Near Washington, DC
 http://tfp2016.org/


The symposium on Trends in Functional Programming (TFP) is an
international forum for researchers with interests in all aspects of
functional programming, taking a broad view of current and future
trends in the area. It aspires to be a lively environment for
presenting the latest research results, and other contributions (see
below). Authors of draft papers will be invited to submit revised
papers based on the feedback receive at the symposium.  A
post-symposium refereeing process will then select a subset of these
articles for formal publication.

TFP 2016 will be the main event of a pair of functional programming
events. TFP 2016 will be accompanied by the International Workshop on
Trends in Functional Programming in Education (TFPIE), which will take
place on June 7nd.


== INVITED SPEAKERS ==

TFP 2016 is pleased to announce keynote talks by the following two
invited speakers:

* Ronald Garcia, University of British Columbia
* Steve Zdancewic, University of Pennsylvania


== HISTORY ==

The TFP symposium is the heir of the successful series of Scottish
Functional Programming Workshops. Previous TFP symposia were held in
   * Edinburgh (Scotland) in 2003;
   * Munich (Germany) in 2004;
   * Tallinn (Estonia) in 2005;
   * Nottingham (UK) in 2006;
   * New York (USA) in 2007;
   * Nijmegen (The Netherlands) in 2008;
   * Komarno (Slovakia) in 2009;
   * Oklahoma (USA) in 2010;
   * Madrid (Spain) in 2011;
   * St. Andrews (UK) in 2012;
   * Provo (Utah, USA) in 2013;
   * Soesterberg (The Netherlands) in 2014;
   * and Inria Sophia-Antipolis (France) in 2015.
For further general information about TFP please see the TFP homepage.
(http://www.tifp.org/).


== SCOPE ==

The symposium recognizes that new trends may arise through various
routes.  As part of the Symposium's focus on trends we therefore
identify the following five article categories. High-quality articles
are solicited in any of these categories:

Research Articles: leading-edge, previously unpublished research work
Position Articles: on what new trends should or should not be
Project Articles: descriptions of recently started new projects
Evaluation Articles: what lessons can be drawn from a finished project
Overview Articles: summarizing work with respect to a trendy subject

Articles must be original and not simultaneously submitted for
publication to any other forum. They may consider any aspect of
functional programming: theoretical, implementation-oriented, or
experience-oriented.  Applications of functional programming
techniques to other languages are also within the scope of the
symposium.

Topics suitable for the symposium include, but are not limited to:

 Functional programming and multicore/manycore computing
 Functional programming in the cloud
 High performance functional computing
 Extra-functional (behavioural) properties of functional programs
 Dependently typed functional programming
 Validation and verification of functional programs
 Debugging and profiling for functional languages
 Functional programming in different application areas:
   security, mobility, telecommunications applications, embedded
   systems, global computing, grids, etc.
 Interoperability with imperative programming languages
 Novel memory management techniques
 Program analysis and transformation techniques
 Empirical performance studies
 Abstract/virtual machines and compilers for functional languages
 (Embedded) domain specific languages
 New implementation strategies
 Any new emerging trend in the functional programming area

If you are in doubt on whether your article is within the scope of
TFP, please contact the TFP 2016 program chair, David Van Horn.


== BEST PAPER AWARDS ==

To reward excellent contributions, TFP awards a prize for the best paper
accepted for the formal proceedings.

TFP traditionally pays special attention to research students,
acknowledging that students are almost by definition part of new
subject trends. A student paper is one for which the authors state
that the paper is mainly the work of students, the students are listed
as first authors, and a student would present the paper. A prize for
the best student paper is awarded each year.

In both cases, it is the PC of TFP that awards the prize. In case the
best paper happens to be a student paper, that paper will then receive
both prizes.


== SPONSORS ==

TFP is financially supported by CyberPoint, Galois, Trail of Bits, and
the University of Maryland Comput
