• Where is a good place/way to store Windows config files for Python scripts?

  - by thornomad

  I have a script/program I am working on that requires a configuration file (I am using ConfigParser). On linux, I will default to store these variables in ~/.myscript using the os.getenv('HOME') function. With Windows, I know I can use os.getenv('USERPROFILE') to find the User's "home" directory, however, is it a good idea to save a hidden file that way (ie, with the name .myscript)? I don't use Windows, obviously, but wanted to be smart about it for those who do. Is there a standard place/way to store these config variables on Windows?

• Stopping pirates

  - by Pirate for Profit

  Okay, what do I do to stop pirates? Obviously a callhome to internet service. We are considering making some major aspects be dependent on a web service of some sort. Memory offsets and cracking. If I like rand randomly to allocate empty memory on the heap, would this throw off the crackers? I hacked some memory shit for EverQuest back in the dizzay but don't really know much about this. Registry on windows, etc., I know theres ways to identify the computer. That's easily spoofed with hex editor, but if I jumble up the strings in the program would that help? I need to know that + real ideas. I want the serials of their sound cards. Any other ideas?

• IntelliJ: Including jars in a jar artifact

  - by skiaddict1

  Developing on the Mac with IntelliJ 9.0.2. I have a program which depends on two library jars. I have figured out how to get IntelliJ to make me a jar of my source (with the Artifact tab), and even to include the two jars in it. However, if I get a listing of the jar file it produces, it looks like this: com/acme/MyClass1.class com/acme/MyClass2.class ... mylib1.jar myLib2.jar And, no surprises, if I double-click the jar file, it gets a NoClassDefFoundError the first time it tries to access a class in one or other library jar. How do I get IntelliJ to include the two library jars such that the classes are visible?

• Redirected wikipedia request

  - by Le_Coeur

  Hi people, i need to write a program, that can redirect's http://localhost:8080 to en.wikipedia.org, it seems to be easy, but i have some problems(only with wikipedia with another sites works good). I make url to wikipedia: URL url = new URL("http", "en.wikipedia.org", 80, "/wiki"); than URLConnection, extract headers, and when i want connection.getInputStream(), i received message 404 Not Found. So i have tried some hack for host header, because in this way host header is localhost:8080, therefor i have tried to change host header to wikipedia, and it works, but after request in browser http://localhost:8080 wikipedia opens, but url in browser changes to en.wikipedia.org, but i want proceed with localhost :)

• printing menu in terminal and choosing an option, how to?

  - by carlos

  I'm a haskell beginner. I'm trying to make a program that shows a menu through terminal and ask user to introduce an option. Here is the code: main :: IO () main = do putStrLn "0 <- quit" putStrLn "1 <- Hello" putStr "Choose an option: " c <- getChar case c of '0' -> return () '1' -> putChar '\n' >> putStrLn "Hello World" >> main When I use this module in the ghci interpreter everything works like it's suposed to do. But if i compile this with: ghc hello.hs and run it in the terminal, it doesn't display the line "Choose an option:" before ask for a char to be introduced. I think this may be caused because of haskell lazy nature and I don't know how to fix it. Any ideas?

• Explanation needed for sum of prime below n numbers

  - by Bala Krishnan

  Today I solved a problem given in Project Euler its problem no 10 and it took 7 hrs for my python program to show the result. But in that forum itself a person named lassevk posted solution for this and it took only 4 sec. And its not possible for me to post this question in that forum because its not discussion forum. So, think about this if you want to mark this question as non-constructive. marked = [0] * 2000000 value = 3 s = 2 while value < 2000000: if marked[value] == 0: s += value i = value while i < 2000000: marked[i] = 1 i += value value += 2 print s If any one understand this code please explain it simple as possible. Link to the Problem 10 question.

• After pip installing uWSGI there's no /etc/uwsgi/ directory - how can I use apps-enabled?

  - by orokusaki

  I've been using apt-get install uwsgi to install uWSGI. Today, I realized I needed a feature that's not available until uWSGI 1.1, and Ubuntu 12.04.1 doesn't have anything after 1.0.x, at least according to my apt-get install uwsgi=1.1 attempt. So, I used: pip install http://projects.unbit.it/downloads/uwsgi-lts.tar.gz After doing so, I get a message prescribing the use of /usr/local/bin/uwsgi to launch the program. I'm not a guru when it comes to compiling from source, but my understanding is that when you do so, nothing will be changed in the /etc/ directory. Is this correct? If not, why don't I have a /etc/uwsgi/ directory and, more specifically, a /etc/uwsgi/apps-enabled/ directory? Should I simply create the directories when installing uWSGI from source? I was hesitant to do so, considering there is no mention of this in the docs (I don't want something that accidentally works, etc.).

• c arrays: setting size dynamically?

  - by user336994

  Hello, I am new to C programming. I am trying to set the size of the array using a variable but I am getting an error: Storage size of 'array' isn't constant !! 01 int bound = bound*4; 02 static GLubyte vertsArray[bound]; I have noticed that when I replace bounds (within the brackets on line 02) with the number say '20', the program would run with no problems. But I am trying to set the size of the array dynamically ... Any ideas why I am getting this error ? thanks much,

• Write a function in c that includes the following sequence of statements [Wont Compile]

  - by Cody

  There is a question in my programming languages textbook that is as follows: Write a C function that includes the following sequence of statements: x = 21; int x; x = 42; Run the program and explain the results. Rewrite the same code in C++ and Java and compare the results. I have written code, and played with it in all three languages but I can not even get it to compile. This includes declaring x above the three lines as well as in the calling function (as this question is obviously attempting to illustrate scoping issues) I'd like to explain the results and do the comparisons on my own, as it is an assignment question but I was wondering if anyone had any insight as to how to get this code to compile? Thanks

• Python having problems writing/reading and testing in a correct format

  - by Ionut

  I’m trying to make a program that will do the following: check if auth_file exists if yes - read file and try to login using data from that file - if data is wrong - request new data if no - request some data and then create the file and fill it with requested data So far: import json import getpass import os import requests filename = ".auth_data" auth_file = os.path.realpath(filename) url = 'http://example.com/api' headers = {'content-type': 'application/json'} def load_auth_file(): try: f = open(auth_file, "r") auth_data = f.read() r = requests.get(url, auth=auth_data, headers=headers) if r.reason == 'OK': return auth_data else: print "Incorrect login..." req_auth() except IOError: f = file(auth_file, "w") f.write(req_auth()) f.close() def req_auth(): user = str(raw_input('Username: ')) password = getpass.getpass('Password: ') auth_data = (user, password) r = requests.get(url, auth=auth_data, headers=headers) if r.reason == 'OK': return user, password elif r.reason == "FORBIDDEN": print "Incorrect login information..." req_auth() return False I have the following problems(understanding and applying the correct way): I can't find a correct way of storing the returned data from req_auth() to auth_file in a format that can be read and used in load_auth file PS: Of course I'm a beginner in Python and I'm sure I have missed some key elements here :(

• Could not load file or assembly error even when reference has been removed

  - by twal

  Could not load file or assembly 'Payflow_dotNET_2.0' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) I tried to reference the payflow SDK and got this error.But I am no longer trying to reference it. I have removed all references to this dll. and Now I am just trying to get the project to start in VS but I still get this error. I am not trying to add the dll anymore.If i have removed the reference to this, why am I still getting this error? How can I remove anything else that may still be causing my program to look for this file? Thanks!

• Automatic upload of 10KB file to web service?

  - by Joseph Turian

  I am writing an application, similar to Seti@Home, that allows users to run processing on their home machine, and then upload the result to the central server. However, the final result is maybe a 10K binary file. (Processing to achieve this output is several hours.) What is the simplest reliable automatic method to upload this file to the central server? What do I need to do server-side to prevent blocking? Perhaps having the client send mail is simple and reliable? NB the client program is currently written in Python, if that matters.

• Create Generic Class Instance from Static Method in a Derived Class

  - by user343547

  I have a class in C# with a template and static method similar to class BClass<T> { public static BClass<T> Create() { return new BClass<T>(); } } From this I derive a class and specify a template parameter to the base class class DClass : BClass<int> { } A problem occurs when I try to use the static method to create an instance of D class Program { static void Main(string[] args) { DClass d = DClass.Create(); } } Gives a compiler error "Cannot implicitly convert type 'Test.BClass<int ' to 'Test.DClass'." Adding the below cast leads to a runtime casting exception. DClass d = (DClass)DClass.Create(); Is there any succint way to allow the static method to create instances of the derived class? Ideally I would like the equivalent of a c++ typedef and I don't want the below syntax (which does work). BClass<int> d = DClass.Create();

• Python Profiling In Windows, How do you ignore Builtin Functions

  - by Tim McJilton

  I have not been capable of finding this anywhere online. I was looking to find out using a profiler how to better optimize my code, and when sorting by which functions use up the most time cumulatively, things like str(), print, and other similar widely used functions eat up much of the profile. What is the best way to profile a python program to get the user-defined functions only to see what areas of their code they can optimize? I hope that makes sense, any light you can shed on this subject would be very appreciated.

• Practical Python-based visual programming environment?

  - by Who8MyLunch

  I am looking for a practical visual programming environment based on Python. My primary application is algorithm development for processing remote-sensing imagery. I was initially inspired by LabVIEW from National Instruments, but that is more geared towards laboratory measurements and simulations. I write a lot of prototype code in Python and do a lot of interactive analysis with IPython. Does there exist a visual framework where a "program" is represented by connected nodes which each read data, do some work, and output data to the next node? I would like to use Python to write the code residing in each node. So far the best I've seen is Orange http://www.ailab.si/orange/, but it does not have the ability to start/stop individual nodes.

Now i want to know that if there is any kind of software that can help me to trace if there is any kind of port blocking from one site to my service location with information of blocker host.

• Values of Variables Matrix NumPy

  - by Max Mines

  I'm working on a program that determines if lines intersect. I'm using matrices to do this. I understand all the math concepts, but I'm new to Python and NumPy. I want to add my slope variables and yint variables to a new matrix. They are all floats. I can't seem to figure out the correct format for entering them. Here's an example: import numpy as np x = 2 y = 5 w = 9 z = 12 I understand that if I were to just be entering the raw numbers, it would look something like this: matr = np.matrix('2 5; 9 12') My goal, though, is to enter the variable names instead of the ints.

• C# Custom Control Properties load before Load and arrays are empties

  - by Wildhorn

  Hello, I made a custom control with custom properties. When I modify these properties in the "Form.cs [Design]", I need stuff to happens (it fill some arrays and modify the look of the control), so I call a function within the "set" of the property. All of this works good. My problem is that when I run the program with my custom control, it seems that properties "set" is called, which will call the function, but then, my arrays seems now to have lost all their values and the function use these arrays, but now because they are all empty, it crashes due to NullException blahblahblah. It also seems that properties "set" is called before the control Load (which I guess is called only when it is added to my Form, and not when the Form load). So question is, why does my arrays become empty once I try to run the Form and is there an event that is called before that when the Form load? Thanks

• How to tell process id within Python

  - by R S

  Hey, I am working with a cluster system over linux (www.mosix.org) that allows me to run jobs and have the system run them on different computers. Jobs are run like so: mosrun ls & This will naturally create the process and run it on the background, returning the process id, like so: [1] 29199 Later it will return. I am writing a Python infrastructure that would run jobs and control them. For that I want to run jobs using the mosrun program as above, and save the process ID of the spawned process (29199 in this case). This naturally cannot be done using os.system or commands.getoutput, as the printed ID is not what the process prints to output... Any clues? Edit: Since the python script is only meant to initially run the script, the scripts need to run longer than the python shell. I guess it means the mosrun process cannot be the script's "son process". Any suggestions? Thanks
