• PyGTK/Quickly Add string to ListStore

  - by AllRadioisDead

  I'm trying to build an application that will prompt the user for a string, and then add that string to a Scrolling Listview object using quickly and PyGTK. I've been following this tutorial: http://developer.ubuntu.com/resources/app-developer-cookbook/multimedia/creating-a-simple-media-player/ When I hit the add button, the prompt comes up properly and I'm able to enter the string. The column appears correctly but the list ends up being blank. What am I doing wrong? import gettext from gettext import gettext as _ gettext.textdomain('spiderweb') from gi.repository import Gtk # pylint: disable=E0611 import logging logger = logging.getLogger('spiderweb') from spiderweb_lib import Window from spiderweb.AboutSpiderwebDialog import AboutSpiderwebDialog from spiderweb.PreferencesSpiderwebDialog import PreferencesSpiderwebDialog from quickly import prompts from quickly.widgets.dictionary_grid import DictionaryGrid import os # See spiderweb_lib.Window.py for more details about how this class works class SpiderwebWindow(Window): __gtype_name__ = "SpiderwebWindow" def finish_initializing(self, builder): # pylint: disable=E1002 """Set up the main window""" super(SpiderwebWindow, self).finish_initializing(builder) self.AboutDialog = AboutSpiderwebDialog self.PreferencesDialog = PreferencesSpiderwebDialog # Code for other initialization actions should be added here. self.supported_web_formats = [".net",".html", ".com"] def on_addbutton_clicked(self, widget, data=None): #let the user choose a path with the directory chooser response, string = prompts.string("Enter a string", "Please enter string:", "Sample Text") #make certain the user said ok before working if response == Gtk.ResponseType.OK: #make a list of the supported media files media_files = Gtk.ListStore(str) #add a dictionary to the list of media files media_files.append({"String":string}) #remove any children in scrolled window for c in self.ui.scrolledwindow1.get_children(): self.ui.scrolledwindow1.remove(c) #create the grid with list of dictionaries #only show the File column media_grid = DictionaryGrid(media_files, keys=["File"]) #show the grid, and add it to the scrolled window media_grid.show_all() self.ui.scrolledwindow1.add(media_grid)

• Beginners guide to developing optimization software

  - by Florenc

  I am novice in "serious" programming i.e. applications that deal with real-life applications and software projects that go beyond school assignments. My interests include optimization, operations research, algorithms and lately i discovered how much I do like software design/development/engineering. I have already developed some simple desktop applications for some "famous" problems like TSP using heuristc approaches, a VRP solver (in progress) and so on. While developing this kind of software I actually used basic concepts taught at school such as object-orientation analysis and design. But, I found these courses rather elementary and quite boring (for my expectations). So I decided to go a little further and start developing "real" software (and this is where I realized how important and interesting software engineering/design is.) Now, here's my issue: I can not find a "study guide" for developing software of this kind. Currently, there are numerous resources out there (books, websites, tutorials) in designing and developing complex IS, web applications, smartphone apps but I can't find a book for example entitled "optimization software development". Definetly, someone could claim that "design patterns apply to software in general" but that's not my point. My point is that I could simply use my imagination for "simple" implementations, but what happens, when my imagination can not go further? In other words I'm looking for a guide/path to bridge the gap between: Mathematics-Algorithm Design-Software Engineering-Optimization-Software development

• What is the best way to exploit multicores when making multithread games?

  - by Keeper

  Many people suggest to write a program, and then start optimizing it. But I think that when it's coming to multithreading with multicore, a little think ahead is required. I've read about using threads, and experienced it myself during some courses at the university (still a student). The big question is simple, but a bit abstract: What thread related steps in game design do I need to take, before implementation? Now trying to be more specific. Let's say, as an example, that I'm making a small board game (like Monopoly) that I want to be multithreaded. My goal Is that this multithreaded game will exploit the best of the multicore system, lets say 4-6 cores (like in i7 processors). My answer to this question at the moment is, one thread for each of these four basic components: GUI User Input / Output AI (computer rival) Other game related calculations (like shortest path from A to B, or level up status change) I'm not an expert (yet!), and I'm sure there are better answers out there. Any suggestion, answer, different approach will be helpful. Some thoughts: Maybe splitting the main database is a good way.. (or total disaster.. )

• The 'which' command returns nothing via cron, but works via console

  - by Zárate

  Hi there, I've written a little utility in haXe + Neko that needs to execute some GIT commands. To avoid hardcoding the path to the GIT executable I'd like to use the which command to find out where it is. Everything works as expected when running manually from the console, but not when the the app runs on a cron job. I'm aware of the restricted environment (here or here) when you run a script using cron, but still surprised this doesn't work: /usr/bin/which git >> /home/user/git.txt The text file is created but the content is empty. Again, when run from the console it works as expected. Any ideas? I'm running OS X Leopard, if that helps. Thanks : ) Juan

• Cannot connect to HTTPS port on Ubuntu

  - by Simpleton

  I've installed a new SSL certificate and set up Nginx to use it. But requests time out when trying to hit HTTPS on the site. When I telnet to my domain on port 80 it connects, but times out on port 443. I'm not sure if there's some defaults on Ubuntu preventing a connection. UFW status shows: 443 ALLOW Anywhere netstat -a shows: tcp 0 0 *:https *:* LISTEN nmap localhost shows: 443/tcp open https The relevant block in the Nginx config is: server { listen 443; listen [::]:80 ipv6only=on; listen 80; root /path/to/app; server_name mydomain.com ssl on; ssl_certificate /etc/nginx/ssl/ssl-bundle.crt; ssl_certificate_key /etc/nginx/ssl/server.key; location / { proxy_pass http://mydomain.com; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } }

• Fix: Cant Change or Remove Visual Studio 2008 from DVD

  If you installed Visual Studio 2008 on a 64-bit operating system, you may have trouble when you try ad add or remove functionality by inserting the disk (or remounting the ISO image).  I believe this is because of the path used to install the 32-bit Visual Studio program.  When you run the setup.exe off of the disk, you get this: Clicking on Change or Remove Visual Studio 2008 brings up this dialog: But not long after it appears, it disappears to be replaced with: Microsoft Visual Studio 2008 Setup A problem has been encountered while loading the setup components.  Canceling setup. FIX: Use Add or Remove Programs Launch the Add or Remove Programs dialog in Windows, and find Microsoft Visual Studio Team System 2008 Team Suite ENU (or whichever SKU you installed).  Click Uninstall/Change.  From here you should be able to change your installed components of Visual Studio successfully: Thanks to Brendan for the tip!

• "ant" is not recognized as command in Windows

  - by user1294663

  This is my first time developing Android applications. I'm developing an Android app on Eclipse on Windows 7. I would like to run the Android app from the Windows 7 command line interface. I have my Android device connected to the PC. The workspace directory that I use to store the Android project is C:\Users\Guest\Desktop\Software Applications Development\Java\Android Moblie Applications Projects\Eclipse Indigo for Java EE x64-bit\project workspace I opened the command line interface and I changed the working directory to the Android workspace directory. cd C:\Users\Guest\Desktop\Software Applications Development\Java\Android Moblie Applications Projects\Eclipse Indigo for Java EE x64-bit\project workspace I included Android sdk platform tools directory into the PATH environment variable. c:\Users\admin\Android-sdks\platform-tools Then I entered this into the Windows 7 command line interface: ant debug I have this error message on the cmd: ant is not recognised as an internal or external command, operatable program or batch file. What is the solution to this problem?

• What's the best way to manage reusable classes/libraries separately?

  - by Tom

  When coding, I naturally often come up with classes or a set of classes with a high reusability. I'm looking for an easy, straight-forward way to work on them separately. I'd like to be able to easily integrate them into any project; it also should be possible to switch to a different version with as few commands as possible. Am I right with the assumption that git (or another VCS) is best suited for this? I thought of setting up local repositories for each class/project/library/plugin and then just cloning/pulling them. It would be great if I could reference those projects by name, not by the full path. Like git clone someproject. edit: To clarify, I know what VCS are about and I do use them. I'm just looking for a comfortable way to store and edit some reusable pieces of code (including unit tests) separately and to be able to include them (without the unit tests) in other projects, without having to manually copy files. Apache Maven is a good example, but I'm looking for a language-independent solution, optimally command-line-based.

• Is learning C# as a first language a mistake?

  - by JuniorDeveloper1208

  I know there are similar questions on here, which I've read, but I recently read this post by Joel Spolsky: How can I teach a bright person, with no programming experience, how to program? And it got me thinking about my way of learning and whether it might actually be harmful in the long run. I've dabbled with various languages but C# is my first serious one, I've read "Head First C#" and created a few projects. But after reading the post above I've found it a bit disheartening that I may be going about it all wrong, obviously I respect Joel's opinion which is what has thrown me a bit. I've started reading "Code" as recommended in the reading list and I'm finding it pretty hard going, although enjoyable. I feel like it's taken the shine off of my "noobish hacking about" in Visual Studio. So now I'm unsure as to what path I should take? Should I take a step back and follow Joel's advice and start reading? I guess my main aim is just to become a good programmer, like everyone else, but I don't want to be going into bad practice by learning a .NET language when someone who's opinion I respect thinks that it is harmful. Thoughts?

• Redirect everything except the homepage

  - by Alex

  Is there a way in nginx to redirect everything from domain1.com to domain2.com, except for the homepage? Right now I have: server { listen 80; server_name www.domain1.com domain1.com; rewrite ^ http://domain2.com$uri permanent; } This works, except that I'd like http://domain1.com (without any additional path) to be left alone and not redirected. Basically, I need to redirect everything, to avoid broken links, but I want to use the homepage of domain1 to serve a static file.

• Splitting Pygame functionality between classes or modules?

  - by sec_goat

  I am attempting to make my pygame application more modular so that different functionalities are split up into different classes and modules. I am having some trouble getting pygame to allow me to draw or load images in secondary classes when the display has been set and pygame.init() has been done in my main class. I have typically used C# and XNA to accomplish this sort of behavior, but this time I need to use python. How do I init pygame in class1, then create an instance of class2 which loads and converts() images. I have tried pygame.init() in class 2 but then it tells me no display mode has been set, when it has been set in class1. I am under the impression i do not wnat to create multiple pygame.displays as that gets problematic I am probably missing something pythonic and simple but I am not sure what. How do I create a Display class, init python and then have other modules do my work like loading images, fonts etc.? here is the simplest version of what I am doing: class1: def __init__(self): self.screen = pygame.display.set_mode((600,400)) self.imageLoader = class2() class2: def __init__(self): self.images = ['list of images'] def load_images(): self.images = os.listdir('./images/') #get all images in the images directory for img in self.images: #read all images in the directory and load them into pygame new_img = pygame.image.load(os.path.join('images', img)).convert() scale_img = pygame.transform.scale(new_img, (pygame.display.Info().current_w, pygame.display.Info().current_h)) self.images.append(scale_img) if __name__ == "__main__": c1 = class1() c1.imageLoader.load_images() Of course when it tries to load an convert the images it tells me pygame has not been initialized, so i throw in a pygame.init() in class2 ( i have heard it is safe to init multiple times) and then the error goes to pygame.error: No video mode has been set

• PASS Summit Preconference and Sessions

  - by Davide Mauri

  I’m very pleased to announce that I’ll be delivering a Pre-Conference at PASS Summit 2012. I’ll speak about Business Intelligence again (as I did in 2010) but this time I’ll focus only on Data Warehouse, since it’s big topic even alone. I’ll discuss not only what is a Data Warehouse, how it can be modeled and built, but also how it’s development can be approached using and Agile approach, bringing the experience I gathered in this field. Building the Agile Data Warehouse with SQL Server 2012 http://www.sqlpass.org/summit/2012/Sessions/SessionDetails.aspx?sid=2821 I’m sure you’ll like it, especially if you’re starting to create a BI Solution and you’re wondering what is a Data Warehouse, if it is still useful nowadays that everyone talks about Self-Service BI and In-Memory databases, and what’s the correct path to follow in order to have a successful project up and running. Beside this Preconference, I’ll also deliver a regular session, this time related to database administration, monitoring and tuning: DMVs: Power in Your Hands http://www.sqlpass.org/summit/2012/Sessions/SessionDetails.aspx?sid=3204 Here we’ll dive into the most useful DMVs, so that you’ll see how that can help in everyday management in order to discover, understand and optimze you SQL Server installation, from the server itself to the single query. See you there!!!!!

• Use msysgit/"Git for Windows" to navigate Windows shortcuts?

  - by Darthfett

  I use msysgit on Windows to use git, but I often want to navigate through a Windows-style *.lnk shortcut. I typically manage my file structure through Windows' explorer, so using a different type of shortcut (such as creating hard or soft link in git) isn't feasible. How would I navigate through this type of shortcut? For example: PCUser@PCName ~ $ cd Desktop PCUser@PCName ~/Desktop $ ls Scripts.lnk PCUser@PCName ~/Desktop $ cd Scripts.lnk sh.exe": cd: Scripts.lnk: Not a directory Is it possible to change this behavior, so that instead of getting an error, it just goes to the location of the directory? Alternatively, is there a command to get the path in a *.lnk file?

• Why is rsync.exe [cwRsync] trying to open a port when in client mode?

  - by hemancuso

  I'm trying to use a cygwin compiled version of rsync [the cwrsync package] on Windows and in seemingly whatever configuration I test in there is a request to the user presented by Windows Firewall to allow inbound traffic. If you deny this request, everything works fine - as expected. I'm doing a vanilla push rsync.exe localpath user@remotepath:/absolutepath and it works just fine. I've also attempted this command having deleted ssh from the path and using rsync on local paths - still a firewall prompt. Why is this listen() happening and is there a way I can force the client to not attempt to listen without recompiling and maintaing a patch?

• C# Threading Background Process - Programming - How to?

  - by Magic

  Hello...I have been given the horrible task of doing this. Launch the website Take a screenshot Fill in the form details, click on Next Take a screenshot ... ... ... Rinse. Repeat. Now, with various combinations, this comes up to 300 screenshots. And I have to do this for 4 different browsers. Chrome, Firefox, IE 6 and IE 7. I cannot use tools which will capture the screenshot and store them, such as, SnagIT. I need to take a screenshot, copy it to a Word Document and take the second screenshot and take it to a Word Document. I thought, I will write a tiny utility which will help me do this. Here is the requirement spec that I put up for it - An executable which once launched seats itself in the System Tray. While it is active, all instances of Key Press (Print Scrn), it should write the contents to a Word Document as defined (either a default path or a user defined one). Save the document periodically. Now, my question is - if I am going to develop this using C# (Winforms application), how do I go about doing this. I can do a fair bit of C# programming and I am willing to learn. But I am not able to locate the references for how to do a background process so that it runs in the background. And while it runs, it has to capture the Print Scrn command. Can you folks point me to the right material where I can learn this? Theoretical references should suffice. But if there are practical references, then nothing like it. Thanks!

• Yum install packages to an alternate directory, without chroot?

  - by Stefan Lasiewski

  I would like to use the Foswiki yum repository to install Foswiki (296 packages). The default installation path is /var/lib/, but I want to install it to an alternate location at /opt/www/. In the future, I still want to use yum to check for and apply updates to the packages. Is it possible to use yum to install packages to an location which is different then the default location provided by RPMs? Does Yum provide anything similar to ./configure --prefix=/usr/local/ or rpm --install --prefix=/opt/local? Yum provides the --installroot option, but that appears to primarily for chroot environments.

• Bending of track in a racing game

  - by caius

  I am trying to create a small racing game in which the track would be modeled using a BSpline curve for the path's center line and directional vectors to define the 'bending' of the track at each point. My problem is that I don't know how to calculate the correct bending / slope of the curve, in such a way that it would be optimal or at least visually nice for a car to 'bend in the corner'. My idea was to use the direction of the 2nd derivatives of the curve, however while this approach looks fine for most of the track, there are points in which the 2nd derivative makes sharp 'twists' / very quick 180 degree flips. I also read about 'knots' of bsplines, but I don't know if such 'twist' in 2nd derivatives is a knot or knots are something else. Can you tell me that using a BSpline: 1. How could I calculate a visually nice bending of a track for a racing game? 2. Is it possible to do this by using some simple calculations of centripertal force / gravity? 3. Is it possible to do this by using 1st, 2nd and 3rd derivatives of the BSpline curve? I am not looking for the 'physically correct' bending angle for the track, I would just like to create something which is visually pleasing in a simple game. I am using a framework which has a built-in class for BSpline, including support for 1st, 2nd and 3rd derivatives of the curve.

• JavaApplicationStub Compatibility with all java versions

  - by neelamsharma

  Hi, I am running a Java application on Mac Leopard & on Mac Mini. My Mac Mini upgraded, it is using Java Version 1.6.0_17 and Mac Leopard have version 1.5.0_13. To run that application on Mac Mini I have to copy JavaApplicationStub from path -"/System/Library/Frameworks/JavaVM.framework/Resources/MacOS/JavaApplicationStub" to my application "Content/Resources/Java". But this application successfully run on Mac Leopard. If I do not copy stub at Mac Mini then I am unable to launch application using app by double click, it shows icon for few second then disappears, so in that case I have to run application with its jar. I want that without copying explicitly JavaApplicationStub, how can I run app with all versions of java. If this possible then what changes I have to made? The info.plist file contain JVMVersion is 1.4+. Thanks!

• How to specify an SSH key for Hudson with git plugin?

  - by jlpp

  I've got Hudson (continuous integration system) with the git plugin running on a Tomcat Windows Service. msysgit is installed and the msysgit bin dir is in the path. PuTTY/Pageant/plink are installed and msysgit is configured to use them. The trouble I'm running in to, I think, is that the user who owns the Tomcat/Hudson service (Local System) has no SSH key set up to be able to clone the git repository. When the git Hudson plugin tries to clone it gives the error: $ git clone -o origin git@hostname:project.git "e:\HUDSON_HOME\jobs\Project Trunk\workspace" ERROR: Error cloning remote repo 'origin' : Could not clone git@hostname:project.git ERROR: Cause: Error performing git clone -o origin git@hostname:project.git e:\HUDSON_HOME\jobs\Project Trunk\workspace Trying next repository ERROR: Could not clone from a repository FATAL: Could not clone hudson.plugins.git.GitException: Could not clone My question is, how can I set things up so that the git plugin/msysgit know to use a particular SSH private key when trying to clone? I don't think Pageant will work because the Tomcat service is running as the "Local System" user, but I may be wrong.

  I am new to Django/Python/ mod_wsgi, and I was wondering if I could optimize this file to reduce memory usage: ServerRoot "/home/<foo>/webapps/django_wsgi/apache2" LoadModule dir_module modules/mod_dir.so LoadModule env_module modules/mod_env.so LoadModule log_config_module modules/mod_log_config.so LoadModule mime_module modules/mod_mime.so LoadModule rewrite_module modules/mod_rewrite.so LoadModule setenvif_module modules/mod_setenvif.so LoadModule wsgi_module modules/mod_wsgi.so LogFormat "%{X-Forwarded-For}i %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined CustomLog /home/<foo>/logs/user/access_django_wsgi.log combined ErrorLog /home/<foo>/logs/user/error_django_wsgi.log KeepAlive Off Listen 12345 MaxSpareThreads 3 MinSpareThreads 1 MaxClients 5 MaxRequestsPerChild 300 ServerLimit 4 HostnameLookups Off SetEnvIf X-Forwarded-SSL on HTTPS=1 ThreadsPerChild 5 WSGIDaemonProcess django_wsgi processes=5 python-path=/home/<foo>/webapps/django_wsgi:/home/<foo>/webapps/django_wsgi/lib/python2.6 threads=1 WSGIPythonPath /home/<foo>/webapps/django_wsgi:/home/<foo>/webapps/django_wsgi/lib/python2.6 WSGIScriptAlias /auctions /home/<foo>/webapps/django_wsgi/auctions.wsgi WSGIScriptAlias /achievers /home/<foo>/webapps/django_wsgi/achievers.wsgi
