Re: Wing vs Netbeans IDE?
I've tried Wing but not NetBeans. I would personally recommend Eclipse with the PyDev plugin. I prefer it to Wing by *far* and if you prefer Eclipse to NetBeans for Java then it might be worth your while checking it out. If you take a few minutes to learn a few of the shortcuts in Eclipse you can really cut down the time to do a lot of administrative/organisational tasks. On Windows I remember Eclipse + Pydev being a bit of a memory hog but on OS X and Linux it works smoothly.

Working with propositional formulae in Python
Hey, I'm currently working with propositional boolean formulae of the type 'A (b - c)' (for example). I was wondering if anybody knows of a Python library to create parse trees and convert such formulae to conjunctive, disjunctive and Tseitin normal forms?

Re: Is 3.0 worth breaking backward compatibility?
Have a read of this http://www.b-list.org/weblog/2008/dec/05/python-3000/ It's a response to questions similar to yours by James Bennett On Sun, Dec 7, 2008 at 7:22 PM, walterbyrd [EMAIL PROTECTED] wrote: IMO: breaking backward compatibility is a big deal, and should only be done when it is seriously needed. Also, IMO, most of, if not all, of the changes being made in 3.0 are debatable, at best. I can not think of anything that is being changed that was really a show stopper anyway. At best, I am a casual python user, so it's likely that I am missing something. -- http://mail.python.org/mailman/listinfo/python-list -- http://www.unprotectedhex.com http://www.smashthestack.org -- http://mail.python.org/mailman/listinfo/python-list
Re: Python queue madness
Hrm, it sounds likely that I am using something mutable and that is messing things up. I'll look into it. As for providing sample code to recreate the problem, I would find it difficult I think to provide a simple example that accurately reflects what is truly going on so there wouldn't be much point.

Yes, your own code :) Perhaps you put mutable objects into the queue, like a list? and later modify the list in another place? -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list -- http://www.smashthestack.org http://www.unprotectedhex.com -- http://mail.python.org/mailman/listinfo/python-list
Python queue madness
Hey guys, Basically I have a system where component 1, 2 and 3 communicate with each other using two Python Queues, we'll call them R and W. Here is what is happening 1 writes data to W and reads from R 2 reads data from W and writes data it receives from 3 to R (but not data it receives from 1) 3 writes to W The problem is that data being written by 1 to W is appearing back on R.

Issue with select.select() and missing data
Hi guys, I have an issue when using select.select(). I have an application that creates sockets then sends data on them. These sockets are then passed off to a listener which uses select.select() to detect any responses. For some reason every socket can only receive one response before my computer begins to issue ICMP port unreachable messages for that port. The code doing the listening is below. No sockets are returned in the broken list. Can anyone spot anything stupid I'm doing in the following code or think of any reason for this issue? def __listen(self): while self.listening and len(self.notify_q_list) != 0: self.lock.acquire() r_read, r_write, broken = select(self.socket_list, [], [], .1) for sock in r_read: data, addr = sock.recvfrom(2**16) for function_tuple in self.notify_q_list: function_tuple[0].put((True, data, 1, addr, 5.0)) self.lock.release() time.sleep(.1) for sock in self.socket_list: sock.close() self.socket_list = [] Thanks, nnp -- http://www.smashthestack.org http://www.unprotectedhex.com -- http://mail.python.org/mailman/listinfo/python-list
