  • Can one Python project use both 2.x and 3.x code?

    - by Begbie00
    Hi all - I'm going to start on a long (~1-year) programming project in Python. I want to use wxPython for my GUI (supports 2.6), but I also want to use 3.1 for the rest of the project (to start using the 3.x syntax). Is there any way for me to design a project that mixes 2.x and 3.x modules? Or should I just bite the bullet and use either 2.x (preferred, since I really want to learn wxPython) or 3.x throughout? Thanks, Mike

  • Running DOS command through C# just opens blank cmd window

    - by Mohit Deshpande
    I was trying to execute a command through C#, but when I run the following code, a blank cmd window just opens up. The code: string command = string.Format(@"adb install C:\Users\Mohit\Programming\Android_Workspace\{0}\bin\{0}.apk", appName); ProcessStartInfo cmdsi = new ProcessStartInfo("cmd.exe"); cmdsi.Arguments = command; Process cmd = Process.Start(cmdsi); What could be wrong? I am sure the syntax is right.

  • A Turing Machine Question

    - by Hellnar
    Greetings, I have been struggling to find a question regarding this theoretical question, even tho it is not directly a programming question, I believe it is really related. Assume a type of Turing machine which cannot have more than 1000 squares. What would be the relationship between the set of such type of recognizable languages and set of normal recognizable languages.

  • [SOLVED] Single Sign On for intranet with Apache and Linux MIT Kerberos

    - by Beerdude26
    EDIT: SOLVED! See my answer below. Greetings, I am looking for a way to do a single sign on to an intranet in the following manner: A Linux user logs on via a graphical frontend (for example, GNOME). He automatically requests a TGT for his username from the MIT Kerberos KDC. Via some way or another, the Apache server (which we'll assume is on the same server as the KDC), is informed that this user has logged in. When the user accesses the intranet, he is automatically granted access to his web applications. I don't think I've seen this kind of functionality while searching the net. I know the following possibilities exist: Using an authentication module such as mod_auth_kerb, a user is presented with a login prompt to enter his username and password, which are then authenticated against the MIT Kerberos server. (I would like this to be automatic.) IIS supports integrated Windows logon via ASP.Net when the user is part of an Active Directory. (I'm looking for the Linux / Apache equivalent.) Any suggestions, criticism and ideas are highly appreciated. This is for a school project to show a proof-of-concept, so every handy piece of information is more than welcome. :)

  • Text-based game graphics in Python

    - by Jasper
    Hi, i'm pretty new 2 programming, and I'm creating a simple text-based game I'm wondering if there is a simple way to create my own terminal-type window with which I can place coloured input etc. Is there a graphics module well suited to this? I'm using Mac, but I would like it to work on Windows as well Thanks

  • Spotlight actually searching every file on "This Mac"

    - by Cawas
    I know of 2 ways to search for any file in your machine using Finder (some say it's Spotlight) and no Terminal. To prevent answers / comments about Terminal, I consider it either for scripting something or as last resource. It's not practical for lots of usages. For instance, if you want to find something to attach to a mail, or embed in iTunes or any other app, you can just drag n' drop one or many of them. Definitely not practical to do under Terminal. There are many cases of use for any, but the focus here is Graphical User Interface. Well, the 2 ways basically are: Press Cmd + Opt + Spacebar and type in your search. Press the + button, select "System files" and "are included". This is so far my preferred way, but I'm not sure it will go through every file. Open Finder, press Cmd + Shift + G and/or select just one folder. Type in your search and select the folder rather than "This Mac". This will bring files not shown in "This Mac" if you select a folder outside of the default scope. Thing is, none of those is really convenient or have the nice presentation from regular Spotlight, which you get from Cmd + Spacebar and just typing. And, as far as I've heard, the default behavior on Spotlight in Tiger was actually being able to find files anywhere. So, is there any way to make the process significantly simpler? Maybe some tweak, configuration or really good Spotlight alternative? I'd rather keep it simple and tweak Spotlight.

  • Conditional or in C#

    - by vikitor
    Hello, I've been programming in JAVA and C all my years at Uni, but now I'm learning C# and building a small application, and I've found troubles with this: if (taxonType.Equals(null) ¦¦ taxonID == -1) I get a red underline for this conditional, and I don't really know why, because according to what I've seen that should be ok, but it is not. Is there something I'm missing? thank you all in advance, Victor

  • Is there a way to avoid debugger?

    - by Gabriel Šcerbák
    I don't like debugging in a debugger, because I think it is often below the abstraction layer of the programming language and it is often not reproducible. I favor usign unit tests when possible and I think they are a good way, but it is not always that easy to implement them. Do you know about any other alternative approaches to avoid the use of debugger?

  • Recommended Clang command line options

    - by frou
    The Manual for Clang seems to be work in progress, so could you help me formulate the definitive command line options for compiling ANSI-C (AKA C89, C90) with maximum strictness and relevant/helpful warnings? Clang is a compiler front end for the C, C++, and Objective-C programming languages. It uses the Low Level Virtual Machine (LLVM) as its back end. It is still under development. Its goal is to offer a replacement to the GNU Compiler Collection (GCC)

  • Ubuntu root privs installation issue

    - by Pam
    I am a fairly new Ubuntu user (and Linux user, for that matter) and I just downloaded a program whose installer was a .sh file. Not thinking, I copied the installer to an /opt subdirectory, thinking that I was going to install the application there: sudo cp ~/Downloads/fooInstaller.sh /opt/someDir I can't remember, but I either had to use sudo because /opt required it, or I just used it without thinking, but in any case, I prefixed with sudo. Once in /opt/someDir, I executed the installer again, using sudo: sudo sh fooInstaller.sh The terminal went crazy, and a few seconds later, a graphical install wizard popped up that guided me through the rest of the process. At the end of the wizard I was prompted to launch the program, and I did, and everything was great. Until... I closed the program, and attempted to add it to my Ubuntu "panel" (the icon panel at the top of the screen). The program was installed to /usr/local/foo/theProgram, and so I specified that URL as the command in the custom app launcher. When I open the program through the panel/launcher (at the top of the screen), the program doesn't load or operate correctly. I get a lot of error messages complaining about being denied permissions. I'm assuming that this is a "superuser/installation/privs" issue, and not a problem with the application (hence this post at superuser.com instead of the application's forums), because when I launch the program from the terminal with sudo, it opens and executes perfectly fine, just like it did the first time around after the install wizard finished. I realize I'm probably going to have to uninstall the program completely, and re-install it differently. Finally, my question: After uninstalling, can I avoid all these issue by just running the installer (sh fooInstaller.sh) right out of my Downloads directory, sans the sudo prefix? If not, how do I get the program to install without root privs so that I can add it to my panel/launcher and get it executing correctly? Sorry for the long post but I didn't want to omit any details because, as I'm sure you can tell, I'm not really sure I know what I'm doing. Thanks for any help here!

  • Adding Parsekit To An Xcode Project

    - by Garry
    I am trying to add the Parsekit framework to my OSX Xcode project. I've never added a 3rd party framework before and I can't get it to work right. I dragged the included Xcode project into my 'Groups & Files' pane and chose to Add it to my project. I then dragged Parsekit.framework underneath the Link Binary With Libraries heading. Then I double-clicked my target app and added Parsekit as a Direct Dependency. I also added libicucore.dylib as a Linked Library (as it says to do this on their site). Finally, in the Build settings tab of my target info I set the Header Search Paths to /Users/path/to/include/directory and the Other Linker Flags to -ObjC -all_load. Running this as a debug build work fine with no errors. However, when I build my app to release and then try to run the executable created, the app fails to load with the following error message: MyApp cannot be opened because of a problem. Check with the developer to make sure myApp works with this version of Mac OS X. Here is the dump from the crash reporter: Process: MyApp [11658] Path: /Users/Garry/Programming/Xcode/Mac/MyApp/build/Release/MyApp.app/Contents/MacOS/MyApp Identifier: com.yourcompany.MyApp Version: ???

  • Python Mindstorms RCX

    - by Kyle Schmidt
    I've got 30 unopened Lego Mindstorms kits that I'd love to use in my intro programming class to do some simple robotics stuff at the end of the year. We're using Python in the class, so I'd prefer there to be a way for the kids to write the programs in Python. Unfortunately, these are old kits with RCX bricks - not the newer NXT ones, so most of the projects like NXT_Python can't help me. Is there any way to make that happen?

  • Why a 10 years old software still is so slow even today?

    - by Cawas
    I just noted this question due to a game (which happens to be Diablo 2), but the matter of fact is: why is my brand new mac book pro, made in 2009 with latest technology (tho it's the cheapest one) can't rival my computer which used to run this much faster back in 2000? Really, it was much faster on my AMD K6 450 back in those days, and I could even run two clients at same time with no slow down. I've always had the feeling this machine was slow, but this is a very odd way to attest it. Granted, the machine is smaller, runs on wifi and "boots" way faster thanks to sleep mode. But other than that, what have we evolved after all?! I'm pretty sure this shouldn't be graphical card's fault. Sure if I buy latest technology it will run fast, and probably most people here can confirm this and won't even understand my question. But the thing is, all the hardware is supposedly much faster and better than the stuff from 10 years ago. The software and operating system became more complex, but also more well refined. Now I'm trying a piece of software that is actually 10 years old and it's not getting any better results! Why?

  • What is a 'thunk'?

    - by fbrereto
    I've seen it used in programming (specifically in the C++ domain) and have no idea what it is. Presumably it is a design pattern, but I could be wrong. Can anyone give a good example of a thunk?
