• How can I debug an unhandled exception in code called from a BackgroundWorker?

  - by SkippyFire

  I am running some import code asynchronously from a simple WinForms app using a BackgroundWorker object and its DoAsync() method. I had a problem where I didn't know that exceptions were being thrown and the thread was prematurely dying. I eventually discovered this, and now know when an exception is thrown after reading Unhandled exceptions in BackgroundWorker. However, I still have a problem while debugging. How do I debug this code? I guess I could run it in a test app that doesn't use a BackgrounWorker, but is there a way to debug this as is? If I step through the code that actually throws the exception, I just get kicked out the step-through when the exception occurs. Re-throwing the exception from the RunWorkerCompletedEventHandler naturally doesn't help much either. Any ideas!? Thanks in advance!

• Core Animation bad access on device

  - by user1595102

  I'm trying to do a frame by frame animation with CAlayers.

• Objective-C global array of ints not working as expected

  - by Fran

  In my MyConstants.h file... I have: int abc[3]; In my matching MyConstants.m file... I have: extern int abc[3] = {11, 22, 33}; In each of my other *.m files... I have #import "MyConstants.h" Inside 1 of my viewDidLoad{} methods, I have: extern int abc[]; NSLog(@"abc = (%d) (%d)", abc[1], sizeof(abc)/sizeof(int)); Why does it display "abc = (0) (3)" instead of "abc = (22) (3)"? How do I make this work as expected?

• How do I read user input in python thread?

• [Python] How do I read binary pickle data first, then unpickle it?

  - by conradlee

  I'm unpickling a NetworkX object that's about 1GB in size on disk. Although I saved it in the binary format (using protocol 2), it is taking a very long time to unpickle this file---at least half an hour. The system I'm running on has plenty of system memory (128 GB), so that's not the bottleneck. I've read here that pickling can be sped up by first reading the entire file into memory, and then unpickling it (that particular thread refers to python 3.0, which I'm not using, but the point should still be true in python 2.6). How do I first read the binary file, and then unpickle it? I have tried: import cPickle as pickle f = open("big_networkx_graph.pickle","rb") bin_data = f.read() graph_data = pickle.load(bin_data) But this returns: TypeError: argument must have 'read' and 'readline' attributes Any ideas?

• Python Eggs on Google App Engine

  - by ott

  Usually I would use virtualenv and pip for deployment of web applications. With Google App Engine this doesn't work, because all import statement are relative to directory of the application. The most common approach I saw was to simply copy the packages from site-packages to the directory of the application. This involves manual work and is error-prone. Another approach was to changes install_lib and install_scripts in ~/.pydisutils.cfg, but this doesn't allow me to use pip in my home directory simultaneously. Do you have any suggestions for this?

• Python, how to tell if screen is running.

  - by Joe Spoon

  Hello, I am very new to programming and am trying to run a python code to see if the screen program is running and if it is then to not run the rest of the code. This is what I have and it's not working. !/usr/bin/python import os var1 = os.system ('screen -r /root/screenlog/screen.log') fd = open("/root/screenlog/screen.log") content = fd.readline() while content: if content == "There is no screen to be resumed.": os.system ('/etc/init.d/tunnel.sh') print "The tunnel is now active." else: print "The tunnel is running." fd.close() I know there are probably several things here that don't need to be and quite a few that I'm missing. I will be running this program in cron. Thanks for any help.

• Implicit parameter in Scalaz

  - by Thomas Jung

  I try to find out why the call Ø in scalaz.ListW.<^> works def <^>[B: Zero](f: NonEmptyList[A] => B): B = value match { case Nil => Ø case h :: t => f(Scalaz.nel(h, t)) } My minimal theory is: trait X[T]{ def y : T } object X{ implicit object IntX extends X[Int]{ def y = 42 } implicit object StringX extends X[String]{ def y = "y" } } trait Xs{ def ys[T](implicit x : X[T]) = x.y } class A extends Xs{ def z[B](implicit x : X[B]) : B = ys //the call Ø } Which produces: import X._ scala> new A().z[Int] res0: Int = 42 scala> new A().z[String] res1: String = y Is this valid? Can I achieve the same result with fewer steps?

• Can someone exaplain me implicit parameters in Scala?

  - by Oscar Reyes

  And more specifically how does the BigInt works for convert int to BigInt? In the source code it reads: ... implicit def int2bigInt(i: Int): BigInt = apply(i) ... How is this code invoked? I can understand how this other sample: "Date literals" works. In. val christmas = 24 Dec 2010 Defined by: implicit def dateLiterals(date: Int) = new { import java.util.Date def Dec(year: Int) = new Date(year, 11, date) } When int get's passed the message Dec with an int as parameter, the system looks for another method that can handle the request, in this case Dec(year:Int) Q1. Am I right in my understanding of Date literals? Q2. How does it apply to BigInt? Thanks

• How to automatically execute python script when Maya first loaded

  - by tep

  Hi, I am new to Maya and trying to figure out how to use Python in Maya. I wanted to create a shelf in Maya and when I click that shelf, it will execute a file containing python code. First thing, I figured out that we can't simply "source" python script. I followed tutorial from http://www.rtrowbridge.com/blog/2008/11/maya-python-import-scripts/, so now I have a function psource(). In my shelf, I can just call psource("myPythonScript") My problem is I have to somehow register psource() when Maya first loaded. Do you have any idea how to do this? Thanks!

• Flex 4: Defining a XML data model in an Actionscript Class

  - by Steve

  I'm really having a hard time accessing a data model I've defined in an Actionscript class in my Flex app. The following is my AS Class (Model.as): package { import mx.rpc.http.HTTPService; public class Model { private static var _instance:Model; public static function getInstance():Model { if (!_instance) _instance = new Model(); return _instance; } [Bindable] public var xml:mx.rpc.http.HTTPService = new mx.rpc.http.HTTPService(); Model.getInstance().xml.url = "http://127.0.01/RAF/DATAPOINTS.xml"; Model.getInstance().xml.resultFormat = "e4x"; } } I'm then trying to access this in my main application with the following code: Model.getInstance().xml.send(); var sectorList:XMLList = Model.getInstance().xml.lastResult; And it just keeps throwing errors. The errors are generic so I can't determine the source in debugging. Hope this is enough info...

• Why "cannot use an object as a parameter to a method"?

  - by Martin

  I have the following ViewController class #import <UIKit/UIKit.h> @interface SampleViewController : UIViewController { IBOutlet UITextField *field1; } @property (nonatomic, retain) UITextField *field1; - (IBAction) method1:(id)sender; @end When I change the method1:(id)sender to method1:(UITextField)sender, I get the error "Cannot use an object as a parameter to a method". I searched and found this post which says "it [using an object as a method parameter] is not a good idea in Objective-C because Objective-C does not allow statically allocated object". Can anyone point out where I can find a more detailed explanation for this? Thank you.

• Dealing with HTTP content in HTTPS pages

  - by El Yobo

  We have a site which is accessed entirely over HTTPS, but sometimes display external content which is HTTP (images from RSS feeds, mainly). The vast majority of our users are also stuck on IE6. I would both of the following Prevent the IE warning message about insecure content Present something useful to users in place of the images that they can't otherwise see; if there was some JS I could run to figure out which images haven't been loaded and replace them with an image of ours instead that would be great. I suspect that the first aim is simply not possible, but the second may be sufficient. A worst case scenario is that I parse the RSS feeds when we import them, grab the images store them locally so that the users can access them that way, but it seems like a lot of pain for reasonably little gain.

• How to create a HTML world map with GeoDjango ?

  The GeoDjango tutorial explains how to insert world borders into a spatial database. I would like to create a world Map in HTML with these data, with both map and area tags. Something like that. I just don't know how to retrieve the coordinates for each country (required for the area's coords attribute). from world.models import WorldBorders for country in WorldBorders.objects.all(): print u'<area shape="poly" title="%s" alt="%s" coords="%s" />' % (v.name, v.name, "???")

• errors with gae-sessions and nose

  - by Kekito

  I'm running into a few problems with adding gae-sessions to a relatively mature GAE app. I followed the readme carefully and also looked at the demo. First, just adding the gaesesions directory to my app causes the following error when running tests with nose and nose-gae: Exception ImportError: 'No module named threading' in <bound method local.__del__ of <_threading_local.local object at 0x103e10628>> ignored All the tests run fine so not a big problem but suggests that something isn't right. Next, if I add the following two lines of code: from gaesessions import get_current_session session = get_current_session() I get the following error: Traceback (most recent call last): File "/Users/.../unit_tests.py", line 1421, in testParseFBRequest data = tasks.parse_fb_request(sr) File "/Users/.../tasks.py", line 220, in parse_fb_request session = get_current_session() File "/Users/.../gaesessions/__init__.py", line 36, in get_current_session return _tls.current_session File "/Library/.../python2.7/_threading_local.py", line 193, in __getattribute__ return object.__getattribute__(self, name) AttributeError: 'local' object has no attribute 'current_session' Any suggestions on fixing the above would be greatly appreciated.

• is this a correct way to generate rsa keys?

• Self-signed ceritificates for many users/browsers/sites

  - by Demiurg

  Here is my problem - I have a lot of users using different browsers accessing many internal web sites using https. I can create my own Certificate Authority, than create a certificate for each server and after that have all the users import it. Obviously, it cannot work in reality - there are too many users and too many sites, and some sites will be added in the future. I'm looking for a way to automate this. Is there a way to create a certificate so that all major browsers (IE, FF, Opera, Chrome and Safari) would trust it for all servers ? If so, what is the best way to install it automatically in all major browsers ?

• How can I get my setup.py to use a relative path to my files?

  - by Chris B.

  I'm trying to build a Python distribution with distutils. Unfortunately, my directory structure looks like this: /code /mypackage __init__.py file1.py file2.py /subpackage __init__.py /build setup.py Here's my setup.py file: from distutils.core import setup setup( name = 'MyPackage', description = 'This is my package', packages = ['mypackage', 'mypackage.subpackage'], package_dir = { 'mypackage' : '../mypackage' }, version = '1', url = 'http://www.mypackage.org/', author = 'Me', author_email = '[email protected]', ) When I run python setup.py sdist it correctly generates the manifest file, but doesn't include my source files in the distribution. Apparently, it creates a directory to contain the source files (i.e. mypackage1) then copies each of the source files to mypackage1/../mypackage which puts them outside of the distribution. How can I correct this, without forcing my directory structure to conform to what distutils expects?

• problem with hierarchical clustering in Python

  - by user248237

  I am doing a hierarchical clustering a 2 dimensional matrix by correlation distance metric (i.e. 1 - Pearson correlation). My code is the following (the data is in a variable called "data"): from hcluster import * Y = pdist(data, 'correlation') cluster_type = 'average' Z = linkage(Y, cluster_type) dendrogram(Z) The error I get is: ValueError: Linkage 'Z' contains negative distances. What causes this error? The matrix "data" that I use is simply: [[ 156.651968 2345.168618] [ 158.089968 2032.840106] [ 207.996413 2786.779081] [ 151.885804 2286.70533 ] [ 154.33665 1967.74431 ] [ 150.060182 1931.991169] [ 133.800787 1978.539644] [ 112.743217 1478.903191] [ 125.388905 1422.3247 ]] I don't see how pdist could ever produce negative numbers when taking 1 - pearson correlation. Any ideas on this? thank you.
