  • Mac OS X pygame input goes to Terminal instead of Python

    - by Parappa
    I'm having trouble running a pygame based app on Mac OS X via Terminal. Input events such as keystrokes go to the Terminal instead of my Python app, and are detected by pygame. For example, I have the following test script: import pygame pygame.init() screen = pygame.display.set_mode((640, 480)) done = False while not done: pygame.event.pump() keys = pygame.key.get_pressed() if keys[pygame.K_ESCAPE]: done = True if keys[pygame.K_SPACE]: print "got here" Neither K_ESCAPE nor K_SPACE will be handled by this script when I run it from a Mac OS X Terminal, but Terminal will echo back the spaces. I'm running the MacPorts port of pygame (py-game), which depends on Python 2.4, and I've also used python_select to make python24 the active version.

  • A better way of switching between Android source versions

    - by dan
    I would like to be able to switch between various android releases (1.0, 1.5, 2.0, etc.) and then access them via the file system to copy all files for that version into a tarball. Currently I am just running repo init -u <source URL> -b release-1. to get each version (changing the tag for each version I need). If this was a single git, I could check out the branch/tag I needed and the prject directory would "morph" to reflect then and I could just tar that folder. since the android source is split into multiple git repositories controlled by repo I have not yet found a way to change this other then the method mentioned above. any suggestions are appreciated.

  • python foursquare - SSL3 certificate verify failed

    - by user1814277
    I'm trying to make a userless request to the Foursquare API using Mike Lewis' Python wrapper - https://github.com/mLewisLogic/foursquare: client = foursquare.Foursquare(client_id=Client_ID, client_secret=Client_Secret) categs = client.venues.categories() Intermittently, I get a "Error connecting to Foursquare API" msg. Running a logger to catch a more detailed message produces: "SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed" This didn't use to happen and occurs both on my local Windows development machine and on a server running ubuntu. Am I missing something basic here about security certificates? The problem is intermittent and sometimes just leaving it a minute and retrying fixes the problem temporarily. I've downloaded the latest 20120716 version of the wrapper although in the code for init.py it still says API_VERSION = '20120608'. I'm using Python 2.73 and have also signed up for the Foursquare API key, using the id and secret in the above code. I listed the urls, using my local IP:8000 and tried using separate keys for the local and dev machines but this seems to make no difference. Help much appreciated. Thanks.

  • Install TurboGears on windows xp

    I've been trying to get TurboGears installed on Windows by following this site.

  • How do I memoize expensive calculations on Django model objects?

    - by David Eyk
    I have several TextField columns on my UserProfile object which contain JSON objects. I've also defined a setter/getter property for each column which encapsulates the logic for serializing and deserializing the JSON into python datastructures. The nature of this data ensures that it will be accessed many times by view and template logic within a single Request. To save on deserialization costs, I would like to memoize the python datastructures on read, invalidating on direct write to the property or save signal from the model object. Where/How do I store the memo? I'm nervous about using instance variables, as I don't understand the magic behind how any particular UserProfile is instantiated by a query. Is __init__ safe to use, or do I need to check the existence of the memo attribute via hasattr() at each read? Here's an example of my current implementation: class UserProfile(Model): text_json = models.TextField(default=text_defaults) @property def text(self): if not hasattr(self, "text_memo"): self.text_memo = None self.text_memo = self.text_memo or simplejson.loads(self.text_json) return self.text_memo @text.setter def text(self, value=None): self.text_memo = None self.text_json = simplejson.dumps(value)

  • Multi-level clones with Git?

    - by Chad Johnson
    So, I'm thinking of having the following centralized setup with Git (each of these are clones): stable development developer1 developer2 developer3 So, I created my stable repository git --bare init made the 'development' clone git clone ssh://host.name//path/to/stable/project.git development and made a 'developer' clone git clone ssh://host.name//path/to/development/project.git developer So, now, I make a change, commit, and then I push from my developer account git commit --all git push and the change goes to the development clone. But now, when I ssh to the server, go to the development clone directory, and run "git fetch" or "get pull", I don't see the changes. So what do I do? Am I totally misunderstanding things and doing things wrong? How can I see the changes in the 'development' clone that I pushed from my 'developer' clone? This worked fine in Mercurial.

  • iPhone -- initialization partly by NSKeyedUnarchiver and partly by other means

    - by William Jockusch
    I have an object myObj, which is an instance of a class MyClass. Some of its instance variables always have their initial values passed in by the calling code. Other instance variables will be initialized in one of two ways. For an instanceArray of type NSMutableArray, the possibilities are either instanceArray = [[NSMutableArray alloc]init]; or instanceArray = [someKeyedUnarchiver decodeObjectForKey: kInstanceArrayKey]; The calling code should determine which of the above will be used. Any particular design pattern I should prefer?

  • Spring @Autowired and WebApplicationContext in Tomcat

    - by EugeneP
    @Autowired works only once. What to do to make it wire the bean every time the Servlet is recreated? My web-app (Tomcat6 container) consists of 2 Servlets. Every servlet has private fields. Their setters are marked with @Autowired In the init method I use WebApplicationContextUtils ... autowireBean(this); It autowires the properties marked with @Autowired once - during the initialization of the Servlet. Any other session will see these fields values, they will not be rewired after the previous session is destroyed. What to do to make them rewire them each time a Servlet constructor is called? a) Put the autowiring into the constructor? Or better 2) get a web app context and extract a bean from there?

Missed something? or I cannot test -initWithNibName using Logic Tests technique. Thanks in advance for your help.

  • Problems with HMAC when switching to Java 6

    We have recently switched to java6 and it's mandatory in the project. One of our apps that used to work is failing, with this stacktrace (relevant part) java.lang.NoClassDefFoundError: Could not initialize class com.apple.crypto.provider.HmacSHA1 sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) java.lang.reflect.Constructor.newInstance(Constructor.java:513) java.lang.Class.newInstance0(Class.java:355) java.lang.Class.newInstance(Class.java:308) java.security.Provider$Service.newInstance(Provider.java:1221) javax.crypto.Mac.a(DashoA13*..) javax.crypto.Mac.init(DashoA13*..)

  • Making php-mode Compatible with Emacs 23

    - by Kristopher Johnson
    I am using Emacs 23 and php-mode.el 1.5.0. When I have this in my .emacs: (require 'php-mode) I get this error message when Emacs starts: Warning (initialization): An error occurred while loading `/Users/kdj/.emacs': error: `c-lang-defconst' must be used in a file To ensure normal operation, you should investigate and remove the cause of the error in your initialization file. Start Emacs with the `--debug-init' option to view a complete error backtrace. If I evaluate (require 'php-mode) after Emacs starts, I don't get any error messages. I found a blog entry which indicates that this problem is specific to Emacs 23 (that is, there is no error with Emacs 22.x), but it doesn't give any solutions. Don't know if this matters, but I'm using Mac OS X, and I built Emacs from the current CVS sources, using ./configure --with-ns. Anybody know what's going on here, and/or how I can fix it?

  • Google Toolbox For Mac with Core Data on iPhone results in error

    - by JaanusSiim
    I have set up my project for using Google Toolbox for Mac as described on official wiki. And everything is working as expected. For core data usage I have created a 'database' class that uses for final application SQLite storage (this is done based on Xcode template code). For unit tests I have created separate init method for 'database' to use in memory storage (storage url is [NSURL URLWithString:@"memory://store"] and type NSInMemoryStoreType). Without adding my model file (*.xcdatamodel) to unit tests target, test fail in expected place with message: executeFetchRequest:error: A fetch request must have an entity. If I add model file to the test target, then test is executed as expected (core data part looks OK), but after tests execution I get: RunIPhoneUnitTest.sh: line 123: 9487 Segmentation fault "$TARGET_BUILD_DIR/$EXECUTABLE_PATH" -RegisterForSystemEvents Command /bin/sh failed with exit code 139 This problem does not looks directly related to core data, but only happens if model file is added to target. Any pointers on resolving this issue would be appreciated!

  • Best practice for copying private instance vars with NSCopying

    - by Ben
    I might be missing something obvious here, but I'm implementing NSCopying on one of my objects. That object has private instance variables that are not exposed via getters, as they shouldn't be used outside the object. In my implementation of copyWithZone:, I need alloc/init the new instance, but also set up its state to match the current instance. I can obviously access current private state from inside copyWithZone:, but I can't set it into the new object, because there are no accessors for that state. Is there a standard way around this while still keeping data privacy intact? Thanks.

  • Is it Pythonic to have a class keep track of its instances?

    - by Lightbreeze
    Take the following code snippet class Missile: instances = [] def __init__(self): Missile.instances.append(self) Now take the code: class Hero(): ... def fire(self): Missile() When the hero fires, a missile needs to be created and appended to the main list. Thus the hero object needs to reference the list when it fires. Here are a few solutions, although I'm sure there are others: Make the list a global, Use a class variable (as above), or Have the hero object hold a reference to the list. I didn't post this on gamedev because my question is actually more general: Is the previous code considered okay? Given a situation like this, is there a more Pythonic solution?

  • grails metaprogramming

    - by Don
    Hi, My understanding is that there are two obvious places in a Grails app where one can do meta-programming: The init closure of Bootstrap.groovy The doWithDynamicMethods closure of a plugin The meta-programming I'm referring to here should be visible throughout the metaprogramming, typical examples include adding (or replacing) methods of 3rd party classes. String.metaClass.myCustomMethod = { /* implementation omitted */ } The disadvantage of (1), is that the metaprogramming won't be applied when the application is dynamically reloaded. The disadvantage of (2) is that I need to create and maintain an entire plugin just for the sake of a little metaprogramming. Is there a better place to do this kind of metaprogramming? Thanks, Don

  • Multiple ParticleSystems in cocos2d

    - by Mattias Akerman
    I wonder about what road I should go with ParticleSystem. In this particular case I want to create 1-20 small explosions at the same time but with different positions. Right now I'm creating a new ParticleSystem for each explosion and then release it, but of course this is very punishing to the performance. My question is: Is there a way to create one ParticleSystem with multiple emitting sources. If not should I create an array of ParticleSystem in init and then use a free one when an explosion is needed? Or is there another approach I haven't thought of?
