  • Get path of inserted usb in dbus

    - by kjakeb
    Hello, I'm writing a program in python using dbus that detects inserted usb drives and manipulates the files inside of them. However, I can't seem to retrieve the path on my system of an inserted usb. Is there someway that I can get the path of an inserted usb in dbus, perhaps by using the GetProperty() method? I have tried using GetProperty("block.device"), but that returns /dev/sdc1 which doesn't exist on my system. Thanks in advance for any help!

  • Why do I need to call new?

    - by cam
    It seems like I could program something without ever using the word 'new', and I would never have to worry about deleting anything either. From what I understand, it's because I would run out of stack memory. Is this correct? I guess my main question is, when should I call 'new'?

  • how to use drawItems() in PyQt?

    - by DSblizzard
    I have these two code fragments in program: class TGraphicsView(QGraphicsView): def __init__(self, parent = None): print("__init__") QGraphicsView.__init__(self, parent) def drawItems(self, Painter, ItemCount, Items, StyleOptions): print("drawItems") Brush = QBrush(Qt.red, Qt.SolidPattern) Painter.setBrush(Brush) Painter.drawEllipse(0, 0, 100, 100) ... Mw.gvNavigation = TGraphicsView(Mw) # Mw - main window Mw.gvNavigation.setGeometry(0, 0, Size1, Size1) Mw.gvNavigation.setScene(Mw.Scene) Mw.gvNavigation.setSceneRect(0, 0, Size2, Size2) Mw.gvNavigation.show() _init_ works, Mw.gvNavigation is displayed and there are Mw.Scene items in it, but drawItems() isn't called. Please explain, what I'm doing wrong.

    - by Sophie
    I'm trying to give a file as input, have it changed within the program, and save the result to a file that is output. But the output file is the same as the input file. :/ Total n00b question, but what am I doing wrong?: puts "Reading Celsius temperature value from data file..." num = File.read("temperature.dat") celsius = num.to_i farenheit = (celsius * 9/5) + 32 puts "Saving result to output file 'faren_temp.out'" fh = File.new("faren_temp.out", "w") fh.puts farenheit fh.close

  • How can we receive a volume attaching notification

    - by Benjamin
    When a volume is attached to file system, on Windows, the Window explorer detects the volume and refreshes automatically. I wonder the technique. How do an program(include device driver) get the notification? -Of course, it doesn’t mean a polling. I want to get an event(or a message). I would like to get the notification when a network volume(like SMB) is attached. Thanks in advance.

  • Fetch MP3 ID3 tag under linux

    - by exic
    Hi, I have a few mp3 files which are not tagged. Winamp has a nice feature which I think is called "autotag" and which is very good at finding out artist and title for files. I'd like something like this for unix, so that I could possibly get artists and titles for my untagged files. Do you know some program which does this? Thanks.

  • Alternative for ZAM 3D editor for Windows 7

    - by drasto
    I'm looking for some 3D editor that allows to create 3D objects and export them to XAML format. Because I'm under Windows Seven ZAM 3D editor is no option for me. I need to create relatively simple(but good looking) 3D objects, no game animations. I prefer simple and intuitive GUI, so Blender is no option for me... It would be good if the program had free trial. Any ides what might help me ? Thank you

  • Opengl Coordinate System

    - by praveen
    Say I am using an Identity Matrix for my modelViewTransformation Matrix on an Open GL ES2.0 program. The Co-ordinate system in this case is the canonical opengl co-ordinate system which extends from (-1,-1,-1) to (1,,1,1). My question is, is this coordinate system right-handed or left-handed? A broader question: Is there a document with OpenGL which can list all the mathematical conventions followed by the API?

  • PHP mysqli error return time

    - by Dori
    Hello. Can i ask a fundamental question. Why when I try to create a new mysqli object in php with invalid database infomation (say an incorrect database name) does it not return an error intstantly? I usually program server stuff in Java and something like this would throw back an error strait away, not after 20 seconds or so. For example $conn = new mysqli($host, $username, $password, $database); Thanks!

  • Why doesn't ifstream read to the end?

    - by user146780
    I'm making a notepad-like program. To get the text from a file I read each character into the buffer by doing while (!file.EOF()) { mystr += file.get(); } however if I load in an exe it stops after MZ but Notepad reads the whole exe. I set my ifstream to binary mode but still no luck. What am I doing wrong? Thanks

  • Link User32 with gcc

    - by Tim Cooper
    I have a C program which has a function call that is defined in windows.h (which I have included), however, when I try and compile it with gcc, I get the error: warning: implicit declaration of function `LockWorkStation' I looked at the MSDN documentation and I see that this function is the User32 library file, and I was wondering how I would go about linking that to my file.

  • Is there an use case for non-blocking receive when I have threads?

    - by Gabriel Šcerbák
    I know non-blocking receive is not used as much in message passing, but still some intuition tells me, it is needed. Take for example GUI event driven applications, you need some way to wait for a message in a non-blocking way, so your program can execute some computations. One of the ways to solve this is to have a special thread with message queue. Is there some use case, where you would really need non-blocking receive even if you have threads?

  • Checking if an int is prime more efficiently

    - by SipSop
    I recently was part of a small java programming competition at my school. My partner and I have just finished our first pure oop class and most of the questions were out of our league so we settled on this one (and I am paraphrasing somewhat): "given an input integer n return the next int that is prime and its reverse is also prime for example if n = 18 your program should print 31" because 31 and 13 are both prime. Your .class file would then have a test case of all the possible numbers from 1-2,000,000,000 passed to it and it had to return the correct answer within 10 seconds to be considered valid. We found a solution but with larger test cases it would take longer than 10 seconds. I am fairly certain there is a way to move the range of looping from n,..2,000,000,000 down as the likely hood of needing to loop that far when n is a low number is small, but either way we broke the loop when a number is prime under both conditions is found. At first we were looping from 2,..n no matter how large it was then i remembered the rule about only looping to the square root of n. Any suggestions on how to make my program more efficient? I have had no classes dealing with complexity analysis of algorithms. Here is our attempt. public class P3 { public static void main(String[] args){ long loop = 2000000000; long n = Integer.parseInt(args[0]); for(long i = n; i<loop; i++) { String s = i +""; String r = ""; for(int j = s.length()-1; j>=0; j--) r = r + s.charAt(j); if(prime(i) && prime(Long.parseLong(r))) { System.out.println(i); break; } } System.out.println("#"); } public static boolean prime(long p){ for(int i = 2; i<(int)Math.sqrt(p); i++) { if(p%i==0) return false; } return true; } } ps sorry if i did the formatting for code wrong this is my first time posting here. Also the output had to have a '#' after each line thats what the line after the loop is about Thanks for any help you guys offer!!!

  • Calculating Connection/Download Speed

    - by kdbdallas
    I have a client and server program (both in Obj-C) and I am transferring files between two devices using the programs. The transferring is working fine, but I would like to display to the user what transfer rate they are getting. So I know the total size of the file, and how much of the file has been transferred, is there a way to figure out the transfer rate from this information, and if not, what information do I need to calculate the transfer rate? Thanks
