Interesting application for RandomIOR
by Jan Skibinski 09 Mar '01

09 Mar '01

Well, at least interesting for me ... Thinking a bit about modelling of a standard interpretation of a measurement in Quantum Mechanics I came up with this tiny addendum to module QuantumVector: http://www.numeric-quest.com/haskell/Observation.hs which simulates apparently random choice of an eigenvalue and collapses the state to its corresponding eigenvector.

PEPM'02, Preliminary Call for Papers
by Peter Thiemann 09 Mar '01

09 Mar '01

PRELIMINARY CALL FOR PAPERS 2002 ACM SIGPLAN Workshop on Partial Evaluation and Semantics-Based Program Manipulation (PEPM'02) Portland, Oregon, USA, January 14-15, 2002 (preceding POPL'02) http://www.informatik.uni-freiburg.de/~thiemann/pepm02 Submission deadline: October, 2001 The PEPM'02 workshop will bring together researchers working in the areas of semantics-based program manipulation, partial evaluation, and program generation. The workshop focuses on techniques, supporting theory, and applications of the analysis and manipulation of programs. Technical topics include, but are not limited to: * Program manipulation techniques: transformation, specialization, normalization, reflection, rewriting, run-time code generation, multi-level programming. * Program analysis techniques: abstract interpretation, static analysis, binding-time analysis, attribute grammars, constraints. * Related issues in language design and models of computation: imperative, functional, logical, object-oriented, parallel, distributed, mobile, secure, domain-specific. * Programs as data objects: staging, meta-programming, incremental computation, mobility, tools and techniques, prototyping and debugging. * Applications: systems programming, scientific computing, algorithmics, graphics, security checking, simulation, compiler generation, compiler optimization, decompilation. * Assessment: applicability of program manipulation techniques to particular architectures and language paradigms, scalability, benchmarking, portability. Original results that bear on these and related topics are solicited. Papers investigating novel uses and applications of program manipulation in the broadest sense are especially encouraged. Authors concerned about the appropriateness of a topic are welcome to consult with the program chair prior to submission. SUBMISSION INFORMATION Papers should be submitted electronically via the workshop's Web page. Exceptionally, submissions may be emailed to the program chair: <URL:mailto:thiemann@informatik.uni-freiburg.de>. Acceptable formats are PostScript or PDF, viewable by gv. Submissions should not exceed 5000 words, excluding bibliography and figures. Excessively long submissions may be rejected outright. Submitted papers will be judged on the basis of significance, relevance, correctness, originality, and clarity. They should include a clear identification of what has been accomplished and why it is significant. They must describe work that has not previously been published in a major forum. Authors must indicate if a closely related paper is also being considered for another conference or journal. Proceedings will be published as a technical report at the University of Freiburg. A special issue of the journal "Higher-Order and Symbolic Computation" <URL:http://www.wkap.nl/journals/lasc> is planned afterwards.

Thanks. Even without this GHC now stands up very well from my perspective. I no longer have an excuse for procrastination! Cheers Mike Thomas.

It takes a hostname and port, and returns a normal Haskell Handle, on which you can use hGetLine and hPutStr as you would with a file or pipe. This is easiest way to open up a connection to a server and communicate with it. > - I also would like to know what does the function readSocket (from > SocketPrim) return. I don't recommend using readSocket. Using the normal Haskell I/O functions with a socket Handle should be enough. Cheers, Simon

Just one question

Hi! I'm a Spanish student who is 'trying' to do her final proyect using Haskell; I don't want to bore you explaining what's the work about but it has to do with internet and all that.Well,currently I'm just trying to do a little code using sockets that (giving it an url) connects to a remote machine and gets information from it. I've checked a library called LibWWW,and I want to do something similar to that, but in a lower level and that's why I'm using another library called SocketPrim. I've managed to get a socket,to connect it but I cannot managed it to read. And now here are the questions: - There's a function in the library Socket called connectTo and I would like to know how does it work 'from the inside'. - I also would like to know what does the function readSocket (from SocketPrim) return. - If you know some site where I may get information related with Haskell about TCP/IP,sockets and all that stuff,I would be very pleased if you send it to me. Well,that's all for now.I hope you can resolve my questions to keep on with the proyect.Thank you very much! Alba ;)

I have compiled up to 4.08.1 (or .2 not sure offhand), if Reuben's advice has changed for later versions then follow them in preference to my experience. As to sed failing - it first happened on a PC in the room next to Ruben's where I was visiting at the time... But these little things are easy to forget in the huge job of compiling GHC - I keep forgetting and wonder why it has broken! Cheers, Nigel

Sigbjorn says: Link with -mwindows (if going via gcc to get at the linker.) i.e., if using the std hello.lhs app ghc -o hello hello.lhs -static -package win32 -optl-mwindows that'll get you a non-console app with mingw. Think it'll do the trick with cygwin too.
