• How do I get my programs to communicate with each other

  - by Benjamin Lindqvist

  I'm basically just getting started with programming. The problem I have with progressing is that I have a hard time learning stuff just for the sake of knowing them - I do better when there's a problem to be solved or a task to be completed so I can learn 'on the job'. So I'm interested in starting some interesting project. I know the basics of Python, Java, Matlab and some C++ aswell and I know enough about microcontrollers to make LED blink etc. The type of stuff I'm looking for is for example scraping some weather forecast site (with Python) and outputting the chance of rain to a LCD display, or a program that makes chrome open and log in to facebook if I say "HAL, time for facebook", or more generally, a program that reads serial/USB input, looks for certain sequences and sends instructions to some other program if it finds one. Do you open some kind of shared stream in which one program reads and one writes? What do I need to read up on to do accomplish this myself? I have no experience with linux or the linux terminal, but looking over peoples shoulders makes me suspect that's what people use. Is that correct?

• Quickbooks Error - Can't turn off auto updates

  - by Murtez

  My company uses quickbooks pro 2002 and unfortunately they won't upgrade at this time, the program keeps freezing and giving methe error: This action cannot be completed because this program is busy.. Then asks to switch or retry, I tracked it down to being an issue with IE since it's an old program and can't use the new versions of IE (the program uses IE for it's interface for some STUPID reason). Everyone says to disable auto updates but the problem is that I can't get to the options area to disable the updates (the options area uses IE!!!) so I'm screwed, I have to sit there and click retry 40-50 times several times a day and it's driving me nutz. I've been looking online for days but have not found a solution to this predicament. Is there a way to disable auto updates through the configuration files? Any help is greatly appreciated.

• Windows 8 isn't detecting PS3 eye

  - by JonFriesen

  I have the PS3 Eye web cam installed with drivers from Code Laboratories, which comes with a test program. When I open the test program it shows a clear picture from the webcam. Every other program does not detect a webcam. The cam shows in my device manager and as installed correctly. My question is, is there a flag or something like that I can set that will show Windows 8 that this device is in fact a camera and is working. Here is a picture of the test program that comes loaded with the drivers and the windows 8 camera app. Thanks for the help! **Here is a pic, I can't integrated because I haven't posted enough on superuser :P http://i48.tinypic.com/6qyw6t.png

• Notepad++ shortcuts not getting copied to the second computer where I want to replicate my settings

  - by Dragos Toader

  In Notepad++, there's a way to assign your custom shortcuts by going to Run - Modify Shortcut/Delete Command... This brings up the Shortcut Mapper I set up my custom shortcuts on Computer 1 I then installed Notepad++ with the same install settings and plugins on Computer 2 I then created a zip archive of my Notepad++ folder in Program Files on Computer 1 I overwrote the Notepad++ folder in Program Files on Computer 2 with this archive My custom shortcuts did not come across. I thought that the shortcuts were saved in C:\Program Files\Notepad++\shortcuts.xml I compared C:\Program Files\Notepad++\shortcuts.xml from Computer 1 with the same file on Computer 2 and the two files are identical. Why then are the shortcuts not coming across to Computer 2? Computer 1 is Windows XP Computer 2 is Windows Server 2008 R2

• How to write code that communicates with an accelerator in the real address space (real mode)?

  - by ysap

  This is a preliminary question for the issue, where I was asked to program a host-accelerator program on an embedded system we are building. The system is comprised of (among the standard peripherals) an ARM core and an accelerator processor. Both processors access the system bus via their bus interfaces, and share the same 32-bit global physical memory space. Both share access to the system's DRAM through the system bus. (The computer concept is similar to Beagleboard/raspberry Pie, but with a specialized accelerator added) The accelerator has its own internal memory (SRAM) which is exposed to the system and occupies a portion of the global address space (as opposed to how a graphics card would talk to teh CPU via a "small" aperture in the system memory space). On the ARM core (the host) we plan on running Ubuntu 12.04. The mode of operation of communicating between the processors should be that the host issues memory transactions on the system bus that are targeted at the accelerator internal memory. As far as my understanding goes, if I write a program for the host that simply writes to the physical address of the accelerator, most chances are that the program will crash due to a segmentation violation. So, I assume that I need some way of communicating with the device in real mode. What is the easiest way to achieve this mode of operation?

• How come Win+R prompt can open Python when it's not in my path?

  - by houbysoft

  When I use the run prompt in Windows XP Professional (Win+R), and type python.exe or python, it works and greets me with the python prompt. However, when I start a cmd window, and then type python.exe or python, it doesn't find it. This is what I expect, as the Python directory (for me, I:\Python31\) is not in my PATH. How come, then, that if I type python.exe in the Win+R prompt, it works? Edit: here is a partial output of SET, I removed most irrelevant entries, I'm not sure why is it useful, apart from the PATH variable which I already said doesn't include the Python directory. If you need a particular variable other than these, please ask. CLIENTNAME=Console CommonProgramFiles=I:\Program Files\Common Files ComSpec=I:\WINDOWS\system32\cmd.exe FP_NO_HOST_CHECK=NO OS=Windows_NT Path=I:\WINDOWS\system32;I:\WINDOWS;I:\WINDOWS\system32\WBEM;I:\WINDOWS\system32\WindowsPowerShell\v1.0;I:\Qt\2010.05\mingw\bin;I:\Program Files\CMake 2.8\bin PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.PSC1 ProgramFiles=I:\Program Files PROMPT=$P$G SESSIONNAME=Console SystemDrive=I: SystemRoot=I:\WINDOWS VBOX_INSTALL_PATH=I:\Program Files\Oracle\VirtualBox\ windir=I:\WINDOWS

• How do I examine my Windows firewall outbound rules?

  - by David

  I need a program to listen to port 9000 on localhost with my Windows firewall. I've created an outgoing and an incoming rule for my program but I can only see my incomming rule in the Windows firewall general menu? I've also noticed that I've many more outgoing rules in my outgoing rule menu but I can only see 4 outgoing rules in my general firewall menu but I see many many more incomming rules? The program doesn't listen to port 9000 or it doesn't working. I've also tried netstat -a -p to no avail. I didn't see 0.0.0.0:9000 in the output? How can I check if my program listen to port 9000 or connect to port 9000 when it's open?

• How to make an x.509 certificate from a PEM one?

  - by Ken

  I'm trying to test a script, locally, which involves uploading a file using a Java-based program to a FileZilla FTPES server. For the real thing, there is a real certificate on the FZ server, and the upload step (tested alone) seems to work fine. I've installed FileZilla Server on my dev box (so it'll test uploading from localhost to localhost). I don't have a real certificate for it, of course, so I used the "Generate new certificate..." button in FZ. It works fine from an interactive FTPES program (as long as I OK the unknown cert), but from my Java program it throws a javax.net.ssl.SSLHandshakeException ("unable to find valid certification path to requested target"). So how do I tell Java that this certificate is OK with me? (I know there's a way to change the Java program to accept any certificate, but I don't want to go down that route. I want to test it just as it will happen in production, and I don't want to ignore unknown certificates in production.) I found that Java has a program called "keytool" that seems to be for managing this sort of thing, but it complains that the certificate file that FZ generated is not an "x.509" file. A posting from the FZ side said it was "PEM encoded". I have "openssl" here, which looks like it's perfect for converting between certificate formats, but I think my understanding of certificate formats is wrong because I'm not seeing anything obvious. My knowledge of security certificates is a bit shaky, so if my title is stupidly wrong, please help by fixing that. :-)

• Looking for a file-system overlay using LD_PRELOAD

  - by ki.lya.online.fr

  Hi, I'm looking for a shared library that is to be loaded using LD_PRELOAD that would modify the view of the filesystem to the client program. Ideally, I'd like to choose the filesystem root (or use / as root) and to overlay the filesystem by renaming filenames. For example, I might want to tell my program to look for /usr/lib/* in /usr/lib32/* instead. Do you know of such a program ? Thanks.

• Problems when rendering code on Nvidia GPU

  - by 2am

  I am following OpenGL GLSL cookbook 4.0, I have rendered a tesselated quad, as you see in the screenshot below, and i am moving Y coordinate of every vertex using a time based sin function as given in the code in the book. This program, as you see on the text in the image, runs perfectly on built in Intel HD graphics of my processor, but i have Nvidia GT 555m graphics in my laptop, (which by the way has switchable graphics) when I run the program on the graphic card, the OpenGL shader compilation fails. It fails on following instruction.. pos.y = sin.waveAmp * sin(u); giving error Error C1105 : Cannot call a non-function I know this error is coming on the sin(u) function which you see in the instruction. I am not able to understand why? When i removed sin(u) from the code, the program ran fine on Nvidia card. Its running with sin(u) fine on Intel HD 3000 graphics. Also, if you notice the program is almost unusable with intel HD 3000 graphics, I am getting only 9FPS, which is not enough. Its too much load for intel HD 3000. So, sin(X) function is not defined in the OpenGL specification given by Nvidia drivers or something else??

• Windows vista firewall exceptions unchangeable

  Hey, I want to allow a program (iTunes) through my windows firewall, so i check it in the program or port list under the exceptions tab (in my windows firewall settings), then i click OK. When i reopen the window the box is unchecked again. Which means i can never get the program through my windows firewall. I think this is a problem due to administrators rights. Because I also can not delete the program from the list. I can however delete other programs from the list. Anybody have any ideas, tips, remarks?

• Resource Acquisition is Initialization in C#

  - by codeWithoutFear

  Resource Acquisition Is Initialization (RAII) is a pattern I grew to love when working in C++.  It is perfectly suited for resource management such as matching all those pesky new's and delete's.  One of my goals was to limit the explicit deallocation statements I had to write.  Often these statements became victims of run-time control flow changes (i.e. exceptions, unhappy path) or development-time code refactoring. The beauty of RAII is realized by tying your resource creation (acquisition) to the construction (initialization) of a class instance.  Then bind the resource deallocation to the destruction of that instance.  That is well and good in a language with strong destructor semantics like C++, but languages like C# that run on garbage-collecting runtimes don't provide the same instance lifetime guarantees. Here is a class and sample that combines a few features of C# to provide an RAII-like solution: using System; namespace RAII { public class DisposableDelegate : IDisposable { private Action dispose; public DisposableDelegate(Action dispose) { if (dispose == null) { throw new ArgumentNullException("dispose"); } this.dispose = dispose; } public void Dispose() { if (this.dispose != null) { Action d = this.dispose; this.dispose = null; d(); } } } class Program { static void Main(string[] args) { Console.Out.WriteLine("Some resource allocated here."); using (new DisposableDelegate(() => Console.Out.WriteLine("Resource deallocated here."))) { Console.Out.WriteLine("Resource used here."); throw new InvalidOperationException("Test for resource leaks."); } } } } The output of this program is: Some resource allocated here. Resource used here. Unhandled Exception: System.InvalidOperationException: Test for resource leaks. at RAII.Program.Main(String[] args) in c:\Dev\RAII\RAII\Program.cs:line 40 Resource deallocated here. Code without fear! --Don

• My Only Gripe With Programming

  - by David Espejo

  Is that im having trouble practicing problems. Even if I decide to practice the problems from my C++ book, they dont give any idea of the way the solution(program) should look like, so that I may compare to see if my program is similar in anyway. My book gives me to many generic "Write a program to do "this" " projects without really showing a concrete example of what "this" really is. In other words How Do I Know That I did "that". One problem in my book said to write a program that calculates the sales tax on a given item????? First of all slase tax differs on state(whats the state,) whats the item(a house, a dog,) How can I check this to see if im right. Programming books dont have answer keys! I know that there is no ABSOLUTE answer, thats just silly, programs can be written in many ways, but a sample of what one would look like based of the difficulty of the problem would really help! Is there a solution to this, maby a book that has worked out examples for the problems they give , or online sources that do something similar.(is there such thing as a programming book with an answer key?)

• Good free software to track and graph memory and CPU usage on Windows?

  - by TheLQ

  There are many questions on Linux memory tracking, but I haven't seen any for Windows. In my case however its a Windows XP Pro box I need to track the memory and CPU usage of. The reason I need it is due to a server program I'm trying that is eating all my processor and some of my memory which is freezing my RDP session and System Explorer and even makes it difficult to login physically. As this is a very constrained server I'm working off of (768 MB RAM with Pentium 4 which disappears with this program), I need a program that doesn't run/require a webserver. I can give it a MySQL database if necessary however. Is there any suggestions for such a program?
