• python: send a list/dict over network

  - by facha

  Hi, everyone I'm looking for an easy way of packing/unpacking data structures for sending over the network: on client just before sending: a = ((1,2),(11,22,),(111,222)) message = pack(a) and then on server: a = unpack(message) Is there a library that could do pack/unpack magic? Thanks in advance

• Several ifstream vs. ifstream + constant seeking

  - by SpyBot

  I'm writing an external merge sort. It works like that: read k chunks from big file, sort them in memory, perform k-way merge, done. So I need to sequentially read from different portions of the file during the k-way merge phase. What's the best way to do that: several ifstreams or one ifstream and seeking? Also, is there a library for easy async IO?

• Efficiently finding the shortest path in large graphs

  - by Björn Lindqvist

  I'm looking to find a way to in real-time find the shortest path between nodes in a huge graph. It has hundreds of thousands of vertices and millions of edges. I know this question has been asked before and I guess the answer is to use a breadth-first search, but I'm more interested in to know what software you can use to implement it. For example, it would be totally perfect if it already exist a library (with python bindings!) for performing bfs in undirected graphs.

• How do I avoid web method parameters using proxy classes?

  - by Alex Angas

  I have a serializable POCO called DataUnification.ClientData.ClientInfo in a .NET class library project A. It's used in a parameter for a web service defined in project B: public XmlDocument CreateNewClient(ClientInfo ci, string system) I now wish to call this web method from project C and use the original DataUnification.ClientData.ClientInfo type in the parameter. However due to the generated proxy class it has now become a different type: WebServices.ClientDataUnification.DataUnificationWebService.ClientInfo. As far as .NET is concerned these are not the same types. How can I get around this?

• Porting a Grails application to GAE

  - by xain

  Hi, I currently have a Grails application I'm evaluating to port to Google App Engine and I'd like to know experiences regarding: Acegi security: the application relies on this library to enforce the security.

• In what situation should the built-in 'operator' module be used in python?

  - by apphacker

  I'm speaking of this module: http://docs.python.org/library/operator.html From the article: The operator module exports a set of functions implemented in C corresponding to the intrinsic operators of Python. For example, operator.add(x, y) is equivalent to the expression x+y. The function names are those used for special class methods; variants without leading and trailing __ are also provided for convenience. I'm not sure I understand the benefit or purpose of this module.

• Memory leak appears only when multiprocessing

  - by Sandro

  I am trying to use python's multiprocessing library to hopefully gain some performance. Specifically I am using its map function. Now, for some reason when I swap it out with its single threaded counterpart I don't get any memory leaks over time. But using the multiprocessing version of map causes my memory to go through the roof. For the record I am doing something which can easily hog up loads of memory, but what would the difference be between the two to cause such a stark difference?
