• Catching a python app before it exits

  - by Leopd

  I have a python app which is supposed to be very long-lived, but sometimes the process just disappears and I don't know why. Nothing gets logged when this happens, so I'm at a bit of a loss. Is there some way in code I can hook in to an exit event, or some other way to get some of my code to run just before the process quits? I'd like to log the state of memory structures to better understand what's going on.

• Capitalization of Person names in programming

  - by Albert

  Hey all, Is anyone aware of some code/rules on how to capitalize the names of people correctly? John Smith Johan van Rensburg Derrick von Gogh Ruby de La Fuente Peter Maclaurin Garry McDonald (these may not be correct, just some sample names and how the capitalization could be/work) This seems like a losing battle... If anyone has some code or rules on when and how to capitalize names, let me know :) Cheers, Albert

• use doctest and logging in python program

  - by Luke

  #!/usr/bin/python2.4 import logging import sys import doctest def foo(x): """ foo (0) 0 """ print ("%d" %(x)) _logger.debug("%d" %(x)) def _test(): doctest.testmod() _logger = logging.getLogger() _logger.setLevel(logging.DEBUG) _formatter = logging.Formatter('%(message)s') _handler = logging.StreamHandler(sys.stdout) _handler.setFormatter(_formatter) _logger.addHandler(_handler) _test() I would like to use logger module for all of my print statements. I have looked at the first 50 top google links for this, and they seem to agree that doctest uses it's own copy of the stdout. If print is used it works if logger is used it logs to the root console. Can someone please demonstrate a working example with a code snippet that will allow me to combine. Note running nose to test doctest will just append the log output at the end of the test, (assuming you set the switches) it does not treat them as a print statement.

• Objective-C: How to create a method that will return a UInt8 array from an int

  - by Adam

  I need to create an Objective-C method that converts an int into a byte array. In this instance, I can't use NSArray as a return type, it must be an UInt8 array. I've written a simple method to do this, but it has errors during compile and tells me that I have incompatible return types. Here is the code snippet. Any ideas? - (UInt8[])ConvertToBytes:(int) i { UInt8 *retVal[4]; retVal[0] = i >> 24; retVal[1] = i >> 16; retVal[2] = i >> 8; retVal[3] = i >> 0; return retVal; }

• In windbg, how do I get a heap header address from !heap -l results?

  - by Kevin

  I am playing around with windbg's !heap command, particular the "-l" switch which detects memory leaks. When -l does detect a leak, I am having problems navigating from its results to a stack trace for the source of the leak. Here is a snippet of the results from !heap -l 0:066 !heap -l Searching the memory for potential unreachable busy blocks. Entry User Heap Segment Size PrevSize Unused Flags 0324b500 0324b508 01580000 03230000 20 60 a busy 0324b520 0324b528 01580000 03230000 20 20 a busy 0324b5c8 0324b5d0 01580000 03230000 20 28 a busy Windbg's documentation for !heap tells me to use dt _DPH_BLOCK_INFORMATION with the header address, followed by dds with the blocks' StackTrace field. But the output for !heap -l doesn't specify a header address! It's only specififying Entry, User, Heap, and Segment. I've racked my brain looking over the other commands but can't figure out how to get the header address from any of these fields. Can someone help?

• More advanced usage of interfaces

  - by owca

  To be honest I'm not quite sure if I understand the task myself :) I was told to create class MySimpleIt, that implements Iterator and Iterable and will allow to run the provided test code. Arguments and variables of objects cannot be either Collections or arrays. The code : MySimpleIt msi=new MySimple(10,100, MySimpleIt.PRIME_NUMBERS); for(int el: msi) System.out.print(el+" "); System.out.println(); msi.setType(MySimpleIterator.ODD_NUMBERS); msi.setLimits(15,30); for(int el: msi) System.out.print(el+" "); System.out.println(); msi.setType(MySimpleIterator.EVEN_NUMBERS); for(int el: msi) System.out.print(el+" "); System.out.println(); The result I should obtain : 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 15 17 19 21 23 25 27 29 16 18 20 22 24 26 28 30 And here's my code : import java.util.Iterator; interface MySimpleIterator{ static int ODD_NUMBERS=0; static int EVEN_NUMBERS = 1; static int PRIME_NUMBERS = 2; int setType(int i); } public class MySimpleIt implements Iterable, Iterator, MySimpleIterator { public MySimple my; public MySimpleIt(MySimple m){ my = m; } public int setType(int i){ my.numbers = i; return my.numbers; } public void setLimits(int d, int u){ my.down = d; my.up = u; } public Iterator iterator(){ Iterator it = this.iterator(); return it; } public void remove(){ } public Object next(){ Object o = new Object(); return o; } public boolean hasNext(){ return true; } } class MySimple { public int down; public int up; public int numbers; public MySimple(int d, int u, int n){ down = d; up = u; numbers = n; } } In the test code I have error in line when creating MySimpleIt msi object, as it finds MySimple instead of MySimpleIt. Also I have errors in for-each loops, because compiler wants 'ints' there instead of Object. Anyone has any idea on how to solve it ?

• What are the differences between GIT and SVN when it comes to merge conflicts solving.

  - by chalup

  I keep hearing that branching in git is so much easier than in SVN, because it's easier to merge the branch back to trunk/master. I've read some tutorials, but they only covered basic merge conflicts ("Alice changed line 8 of code.cpp and at the same time Bob changed line 8 of code.cpp...") and there are no differences between SVN and all other distributed source control systems. Can you give me the examples of changes in branch that would cause troubles in SVN repository, but would be handled gracefully by git?

• EXEC_BAD_ACCESS in UITableView cellForRowAtIndexPath

  - by David van Dugteren

  My UITable is returning EXEC_BAD_ACCESS, but why! See this code snippet! Loading the UITableView works fine, so allXYZArray != nil and is populated! Then scrolling the tableview to the bottom and back up causes it to crash, as it goes to reload the method cellForRowAtIndexPath It fails on line: "NSLog(@"allXYZArray::count: %i", [allXYZArray count]);" - (UITableViewCell *)tableView:(UITableView *)theTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"CellIdentifier"; UITableViewCell *cell = [theTableView dequeueReusableCellWithIdentifier:CellIdentifier]; cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; @try { if (allAdviceArray == nil) { NSLog(@"nil"); allXYZArray = [ToolBox getMergedSortedDictionaries:allXYZGiven SecondDictionary:allXYZSought]; } NSLog(@"%i", [indexPath row]); NSLog(@"allXYZArray::count: %i", [allXYZArray count]);

• TraceMonkey and GNU GPL license

  - by JavaMan

  I am trying to embed a Javascript engine into my application. But the license for Mozilla Javascript engine is GNU/GPL/MPL based and I don't have the time and energy to digest the cryptic legal document. In short, does the license mean I need to publish my application's source code if I embed the engine into my own appli.? Something I think is quite impossible but as what i understand from the CopyLeft license, any work derived from modifying the source code means the derived work must be made open source as well.

• HTML Comment-out Add-In

  - by Velika

  Here is an old add in to quickly comment out HTML code. Maybe I am missing it, but it seems like there is a shortcut in VS2010 to scratch your tail with one click but commenting out HTML code is still awkward as hell. What's the easiest way to get a function like this working? Can I expect any add-ins that were written for older versions of VS to work in VS2010 w/o an upgrade?

• Ruby CMS/blog: Mephisto vs. Radiant

  - by Candidasa

  I'm looking for a blogging tool with some light CMS features in Ruby on Rails. I mainly want something simple, but configurable. I have no need for page snippets, etc. Just your basic main blog, very good (and easy) theme support, some nice sidebar stuff, a few static pages and MetaWeblog API support. I'm thinking of either using Mephisto or Radiant CMS (everything else seems half-baked or extremely lightweight at best): http://mephistoblog.com/ http://www.radiantcms.org/ Documentation for Mephisto seems very lacking and their site is a mess. I've also read some bad things about it's stability. Radiant seems more stable in comparison and has heaps of useful plug-ins. However, it isn't designed for blogging out of the box. That has to be added as almost an after thought. Creating a custom theme also seems more cumbersome with Radiant due to the sub-page/snippet feature. Which should I choose?

• using addListener with WordPress audio player

  - by Jacob

  Hi, I'm trying to add a listener for the stop event in the word press audio player but usage seems to be undocumented. I'm hoping someone who knows a little flash can look at the code and tell me how it works: In the code at http://tools.assembla.com/1pixelout/browser/audio-player/trunk/source/classes/Application.as I see a snippet with this: ExternalInterface.call("AudioPlayer.onStop", _options.playerID); I was hoping that would let me capture the event in javascript with ("player" is the ID of my player) AudioPlayer.addListener("player", "AudioPlayer.onStop", function() { alert('stopped'); }); But my javascript function never seems to get called

• Python lazy property decorator

  - by detly

  Recently I've gone through an existing code base and refactored a lot of instance attributes to be lazy, ie. not be initialised in the constructor but only upon first read. These attributes do not change over the lifetime of the instance, but they're a real bottleneck to calculate that first time and only really accessed for special cases. I find myself typing the following snippet of code over and over again for various attributes across various classes: class testA(object): def __init__(self): self._a = None self._b = None @property def a(self): if self._a is None: # Calculate the attribute now self._a = 7 return self._a @property def b(self): #etc Is there an existing decorator to do this already in Python that I'm simply unaware of? Or, is there a reasonably simple way to define a decorator that does this? I'm working under Python 2.5, but 2.6 answers might still be interesting if they are significantly different.

  I am trying to use AsDoc on the code of one of my projects in flash. Some of the classes that I use inside the code are "exported for actionscript" classes from my FLA file.

• Is TcpClient BeginRead/Send thread safe?

  - by wb

  Using a dotNET TcpClient if I have called an asynchronous BeginRead() on the associated network stream can I still call Write() on that stream on another thread? Or do I have to lock() the TcpClient in the code that is called back from the BeginRead and the code that does the send? Also if I close the TcpClient with: client.GetStream().Close(); client.Close(); Do I have to lock() on the TcpClient as well? Thanks in advance.
