  • Cannot delete .Trash-503 directory, returns a $RECYCLE.BIN.trashinfo: Input/output error

    - by Parto
    I cannot delete .Trash-503 folder via GUI or terminal, it returns a $RECYCLE.BIN.trashinfo: Input/output error Not even sudo rm -r or even a simple ls works in that trash directory. Check terminal output below: subroot@subroot:~$ cd /media/xxxxx/ subroot@subroot:/media/xxxxx$ rm .Trash-503/ rm: cannot remove `.Trash-503/': Is a directory subroot@subroot:/media/xxxxx$ rm -r .Trash-503/ rm: cannot remove `.Trash-503/info/$RECYCLE.BIN.trashinfo': Input/output error rm: cannot remove `.Trash-503/info/found.000.trashinfo': Input/output error rm: cannot remove `.Trash-503/info': Directory not empty subroot@subroot:/media/xxxxx$ sudo rm -r .Trash-503/ [sudo] password for subroot: rm: cannot remove `.Trash-503/info/$RECYCLE.BIN.trashinfo': Input/output error rm: cannot remove `.Trash-503/info/found.000.trashinfo': Input/output error subroot@subroot:/media/xxxxx$ cd .Trash-503/ subroot@subroot:/media/xxxxx/.Trash-503$ ls info subroot@subroot:/media/xxxxx/.Trash-503$ cd info/ subroot@subroot:/media/xxxxx/.Trash-503/info$ ls ls: cannot access $RECYCLE.BIN.trashinfo: Input/output error ls: cannot access found.000.trashinfo: Input/output error found.000.trashinfo $RECYCLE.BIN.trashinfo subroot@subroot:/media/xxxxx/.Trash-503/info$ What's going on here and how can I delete this folder? EDIT I tried checking and repairing the partition using gparted only to get this error message: ERROR: Filesystem check failed! ERROR: 264 clusters are referenced multiple times. NTFS is inconsistent. Run chkdsk /f on Windows then reboot it TWICE! The usage of the /f parameter is very IMPORTANT! No modification was and will be made to NTFS by this software until it gets repaired. I don't have windows installed, how can I run chkdsk /f from ubuntu?

  • Design of input files reading when it comes to defaults/transformations

    - by Stefano Borini
    Suppose you have an application that reads an input file, on a language that does not support the concept of None. The input is read, parsed, and the contents are stored on a structure for later use. Now, in general you want to keep into account transformation of the data from the input, such as adding default values when not specified, or adding full path information to relative path specified in the input. There are two different strategies to achieve this. The first strategy is to perform these transformations at input file reading time. In practice, you put all the intelligence into the input parser, and your application has no logic to deal with unexpected circumstances, such as an unspecified value. You lose the information of what was specified and what wasn't, but you gain in black-boxing the details. Your "running code" needs that information in any case and in a proper form, and is not concerned if it's the default or a user-specified information. The second strategy is to have the file reader a real one-to-one mapper from the file to a memory-stored object, with no intelligent behavior. unspecified values are not filled (which may however be a problem in languages not supporting None) and data is stored verbatim from the file. The intelligence for recovery must now go into the "running code", which must check what was specified in the file, eventually fall back to a default, or modify the input properly before using it. I would like to know your opinion on these two approaches, and in particular which one you found the most frequently implemented.

  • Capture RTSP stream from IP Camera and store

    - by Keerthi
    I've got a few IP Cameras which output an RTSP (h264 mpeg4) stream. Hitting the URL locally via VLC: rtsp://192.168.0.21:554/mpeg4 I can stream the camera and dump to disk (on my desktop). I'd like to however store these files on my NAS (FreeNAS). I was looking at ways to capture the RTSP stream and dump them to disk but I'm unable to find anything. Is it possible to capture the stream on FreeBSD or Linux (RaspberryPi) and dump the streamed content to a disk local to Linux or FreeBSD - preferably every 30minutes? EDIT: The NAS is headless (HP N55L or something) and the RaspberryPi's are headless too. I've already looked into ZoneMinder but need something small. I was hoping maybe using Motion to detect motion on the stream but that will come later.

  • Do input template languages exist?

    - by marczellm
    When I have to create some textual representation of data, I can use a template language, so that my code does not have to worry about the structure of the output file - I can sometimes even write code that's independent of whether the output is XML, LaTeX or any other plain text. A simple example: Template (in separate file): <someXmlTag> $variableName </someXmlTag> Code: Template(temstring).substitute(variableName="value") Result (written to output file): <someXmlTag> value </someXmlTag> I want to do the same, but in the opposite direction. I have XML or plain text or whatever files to input. I want to describe the input structure in a separate file that looks like the input but has these variable declarations in it, and I want to handle it with code that's independent of the structure. Is there a library for this concept? (We usually handle XML input by using an XML parser library to describe the input structure in program code, handle plaintext input by writing regexes in code, and don't handle LaTeX input because LaTeX can't really be parsed.)

  • How to compute palindrome from a stream of characters in sub-linear space/time?

    - by wrick
    I don't even know if a solution exists or not. Here is the problem in detail. You are a program that is accepting an infinitely long stream of characters (for simplicity you can assume characters are either 1 or 0). At any point, I can stop the stream (let's say after N characters were passed through) and ask you if the string received so far is a palindrome or not. How can you do this using less sub-linear space and/or time.

  • How do I convert a System::IO::Stream^ to an LPCSTR for PlaySound?

    - by Jon Cage
    I'm trying to embed and then play back a .wav file in a C++/CLI app but all the examples I've seen which use PlaySound are in VB. I can't see how to get froma Stream^ to the LPCSTR which PlaySound requires: System::IO::Stream^ s = Assembly::GetExecutingAssembly()->GetManifestResourceStream ("Ping.wav"); LPCSTR buf = s->????; PlaySound(buf, NULL, SND_ASYNC|SND_MEMORY|SND_NOWAIT); I guess I need some sort of horrible .net memory conversion magic.

  • How can I use one stream and save result to many places?

    - by plasticrabbit
    I using servlet and Apache ServletFileUpload that provides stream to uploaded image. All I want to do is to store that image to db and also store resized (I using JAI) version to db. How can I achieve this without saving image to drive. As I understand stream can be read only once. So I need to store whole image in memory? Is it expensive for performance? Or there are another way?

  • Joystick input in Java

    - by typoknig
    Hi all, I am making a 2D game in Java and I want to use a joystick to control the movement of some crosshairs. Right now I have it so the mouse can control those crosshairs. My only criteria for this is that the control for the crosshair must stay in the game window unless a user clicks off into another window. Basically I want my game to capture whatever device is controlling the crosshairs much like a virtual machine captures a mouse. The joystick I am using (Thrustmaster Hotas Cougar) comes with some pretty advanced features, so that may make this easier (or harder). I have tried the solution listed on this page, but I am using a 64bit computer and for some reason it does not like that. I have also tried to use the key emulation feature of my joystick, but with little success. Here is what I have so far, any pointer would be appreciated. Main Class: import java.awt.Color; import java.awt.Cursor; import java.awt.event.MouseEvent; import java.awt.event.MouseMotionListener; import java.awt.Graphics; import java.awt.Image; import java.awt.image.BufferStrategy; import java.awt.image.MemoryImageSource; import java.awt.Point; import java.awt.Toolkit; import javax.swing.JFrame; public class Game extends JFrame implements MouseMotionListener{ private int windowWidth = 1280; private int windowHeight = 1024; private Crosshair crosshair; public static void main(String[] args) { new Game(); } public Game() { this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setSize(windowWidth, windowHeight); this.setResizable(false); this.setLocation(0,0); this.setVisible(true); this.createBufferStrategy(2); addMouseMotionListener(this); initGame(); while(true) { long start = System.currentTimeMillis(); gameLoop(); while(System.currentTimeMillis()-start < 5) { //empty while loop } } } private void initGame() { hideCursor(); crosshair = new Crosshair (windowWidth/2, windowHeight/2); } private void gameLoop() { //game logic drawFrame(); } private void drawFrame() { BufferStrategy bf = this.getBufferStrategy(); Graphics g = (Graphics)bf.getDrawGraphics(); try { g = bf.getDrawGraphics(); Color darkBlue = new Color(0x010040); g.setColor(darkBlue); g.fillRect(0, 0, windowWidth, windowHeight); drawCrossHair(g); } finally { g.dispose(); } bf.show(); Toolkit.getDefaultToolkit().sync(); } private void drawCrossHair(Graphics g){ Color yellow = new Color (0xEDFF62); g.setColor(yellow); g.drawOval(crosshair.x, crosshair.y, 40, 40); g.fillArc(crosshair.x + 10, crosshair.y + 21 , 20, 20, -45, -90); g.fillArc(crosshair.x - 1, crosshair.y + 10, 20, 20, -135, -90); g.fillArc(crosshair.x + 10, crosshair.y - 1, 20, 20, -225, -90); g.fillArc(crosshair.x + 21, crosshair.y + 10, 20, 20, -315, -90); } @Override public void mouseDragged(MouseEvent e) { //empty method } @Override public void mouseMoved(MouseEvent e) { crosshair.x = e.getX(); crosshair.y = e.getY(); } private void hideCursor() { int[] pixels = new int[16 * 16]; Image image = Toolkit.getDefaultToolkit().createImage(new MemoryImageSource(16, 16, pixels, 0, 16)); Cursor transparentCursor = Toolkit.getDefaultToolkit().createCustomCursor(image, new Point(0, 0), "invisiblecursor"); getContentPane().setCursor(transparentCursor); } } Another Class: public class Crosshair{ public int x; public int y; public Crosshair(int x, int y) { this.x = x; this.y = y; } }

  • MacOS Virtual Input Devices

    - by computergeek6
    How can I create a virtual HID device in code? I'm trying to avoid writing a kernel extension to accomplish this, but it seems to be the only way. I need to be able to create virtual HID devices of all types, and have an app running in the background feed them events. Is there a way to do this in user-space, or must I venture into kernel land?

  • Removing input background colour for Chrome autocomplete?

    - by DisgruntledGoat
    On a form I'm working on, Chrome is auto-filling the email and password fields. This is fine, however, Chrome changes the background colour to a pale yellow colour. The design I'm working on is using light text on a dark background, so this really messes up the look of the form - I have stark yellow boxes and near-invisible white text. Once the field is focused, the fields return to normal. Is it possible to stop Chrome changing the colour of these fields?

  • Ruby on Rails solution for scrubbing data of WYSIWYG editor user input

    - by Jimmy
    Hey everyone, I am working on a simple blogging type ruby on rails application and I have everything working through tinyMCE for a nice WYSIWYG editor so the user can add some simple things like images/youtube videos and lists. What I am looking for is a nice solution for blacklisting certain elements to be filtered out of the data when it is displayed. So is there a solution for this available as a gem or available to download anywhere? Thanks!

  • Clearing input text feilds when clicked on in Flash (AS 2.0)

    - by rickstyphilis
    I have a problem where I want a text field that by default has the word NAME in it, to become empty when a user clicks on it. The text field has the instance name 'nam' and is inside a movie with the instance name 'input_text'. I've searched around and found samples of code where everyone keeps suggesting this: textboxinstancename.onSetFocus = function() { textboxinstancename.text = ""; }; should work. It seems to work for everyone else but me. I've tried using the following on the first frame of the 'input_text' movie with no luck: this.input_text.nam.onSetFocus = function() { this.input_text.nam.text = "" } I've tried putting this on the first frame of the scene, again with no result: _root.input_text.nam.onSetFocus = function() { _root.input_text.nam.text = "" } I've tried this in the same manner as the last respectively with both 'this' on the instance and '_root' on the scene (denoted by x): x.input_text.nam.onSetFocus = function() { if (x.input_text.nam.text == "NAME") { x.input_text.nam.text = ""; } }; Still no luck. Can anyone tell me what I might be doing wrong?

  • How to provide Input to Dialogs designed by Qt Designer

    - by GG
    Hello, I am a Qt beginner and working with Qt Designer to develop some small UI elements. I read http://doc.trolltech.com/4.5/designer-using-a-ui-file.html to use these GUI elements in my code and using multiple inheritance approach. I am introducing bookmark feature which somewhat look like http://img293.imageshack.us/img293/3041/screenshotyb.png. Now the problem I am facing is How can I show all existing bookmark folders in the drop down(say folders are in a QVector). So my main problem is how can I pass some inputs to the UI element. I think I'm clear, please let me know if further explanation is required. Sorry for adding links directly, rich formatting in my browser is not working. Thanks in advance,

  • JAVA: storing input into array

    - by Jann
    I need to write a program where the program would generate random letter and i would need to store this random character into an array char[] arrayRandom = new char[10]; for (int i = 0; i < 8; i++) { randomNumLet = (generator.nextInt(20) + 1); System.out.print(arrayRandomLetter[randomNumLet] + " "); arrayRandomLetter[randomNumLet] = arrayRandom[i]; } is there anything wrong with my code? because when i run this and printed the array i get boxes for all the values in the array and there are some letter that this line of code cannot print System.out.print(arrayRandomLetter[randomNumLet] + " "); Thanks

  • How are components properly instantiated and used in XNA 4.0?

    - by Christopher Horenstein
    I am creating a simple input component to hold on to actions and key states, and a short history of the last ten or so states. The idea is that everything that is interested in input will ask this component for the latest input, and I am wondering where I should create it. I am also wondering how I should create components that are specific to my game objects - I envision them as variables, but then how do their Update/Draw methods get called? What I'm trying to ask is, what are the best practices for adding components to the proper collections? Right now I've added my input component in the main Game class that XNA creates when everything is first initialized, saying something along the lines of this.Components.Add(new InputComponent(this)), which looks a little odd to me, and I'd still want to hang onto that reference so I can ask it things. An answer to my input component's dilemma is great, but also I'm guessing there is a right way to do this in general in XNA.
