  • Syncing 1TB+ to a iSCSI device, software needed

    - by mojah
    Hi, I need to sync a local disk to a iSCSI mount on Windows (server 2003), and I'm struggling to find software that's capable of doing so in a reasonable timeframe. Notes on the current 1TB disk: - 800GB currently in use - Contains a folder with several hundred thousand subfolders, which in turn have several thousand files, ... So I'm trying to find a piece of software that can handle such large filelists, and give me a good timeframe on when this will be copied. I've tried DeltaCopy (the rSync GUI client for Windows), but it's intolerably slow and doesn't provide me with a good estimate time remaining. DeltaCopy: http://www.aboutmyip.com/AboutMyXApp/DeltaCopy.jsp Does anyone know alternative software for Windows, that would do this well?

  • Preventing threads from writing to the same file

    - by EpsilonVector
    I'm implementing an FTP-like protocol in Linux kernel 2.4 (homework), and I was under the impression that if a file is open for writing any subsequent attempt to open it by another thread should fail, until I actually tried it and discovered it goes through. How do I prevent this from happening? PS: I'm using open() to open the file.

  • Why does this anonymous function starting with println result in a NullPointerException?

    - by noahz
    I am learning about pmap and wrote the following function: (pmap #((println "hello from " (-> (Thread/currentThread) .getName)) (+ %1 %2)) [1 1 1] [-1 -1 -1]) When run, the result is a NullPointerException (hello from clojure-agent-send-off-pool-4 hello from clojure-agent-send-off-pool-3 hello from clojure-agent-send-off-pool-5 NullPointerException user/eval55/fn--56 (NO_SOURCE_FILE:11) Why is this happening? I have understood and observed the body of a fn to be an implicit do.

  • Works on debug but not release

    - by user146780
    I have a thread that sets a value to true when it is done. Until then I wait: while(1) { if(done[0] == true) { break; } } This code works just fine in Debug but in Release it stays in the loop forever even though the debugger clearly says that it is true and not false. Why would this not work? Thanks

  • My Android game runs out of memory when it is closed and opened and couple times.

    - by sirconnorstack
    I have an Android game that has an activity for the menu, and then another activity for the game that creates a SurfaceView and Thread to deal with canvas drawing and game logic. When you exit the game and start it up again too much or if you open and close the keyboard (thus restarting the activity), the game runs out of memory, usually when loading a bitmap: java.lang.OutOfMemoryError: bitmap size exceeds VM budget How can I keep all my images in memory without loading them again when the game changes state, or how can I release them from memory and let them reload when the game is restarted?

  • Locking individual elements in a static collection?

    - by user638474
    I have a static collection of objects that will be frequently updated from multiple threads. Is it possible to lock individual objects in a collection instead of locking the entire collection so that only threads trying to access the same object in the collection would get blocked instead of every thread? If there is a better way to update objects in a collection from multiple threads, I'm all ears.

  • How to achieve in-folder discussions with IMAP (skip SMTP send, Thunderbird)?

    - by lkraav
    Does anyone know a good way to achieve replying to a message into the same IMAP folder without sending another duplicate copy over SMTP? This is to be achieved with a conventional GUI mail client, especially Thunderbird. Goal is to have an in-folder conversation. This is possible with shared IMAP folders, with per-user Seen indices, where subscribed recipients are guaranteed to see the new messages without them arriving from internet. Thunderbird is capable of storing a copy of a reply in the same folder as original message (Account Options), which is half way there. Just pressing Save sends the message into Drafts and that is probably an even bigger patch to try to put a "draft message" into the same folder as original. All options, client, server or logic-wise are an acceptable answer, including programming i.e. patching/creating add-on for Thunderbird.

  • Updating table from async task android

    - by CantChooseUsernames
    I'm following this tutorial: http://huuah.com/android-progress-bar-and-thread-updating/ to learn how to make progress bars. I'm trying to show the progress bar on top of my activity and have it update the activity's table view in the background. So I created an async task for the dialog that takes a callback: package com.lib.bookworm; import android.app.ProgressDialog; import android.content.Context; import android.os.AsyncTask; public class UIThreadProgress extends AsyncTask<Void, Void, Void> { private UIThreadCallback callback = null; private ProgressDialog dialog = null; private int maxValue = 100, incAmount = 1; private Context context = null; public UIThreadProgress(Context context, UIThreadCallback callback) { this.context = context; this.callback = callback; } @Override protected Void doInBackground(Void... args) { while(this.callback.condition()) { this.callback.run(); this.publishProgress(); } return null; } @Override protected void onProgressUpdate(Void... values) { super.onProgressUpdate(values); dialog.incrementProgressBy(incAmount); }; @Override protected void onPreExecute() { super.onPreExecute(); dialog = new ProgressDialog(context); dialog.setCancelable(true); dialog.setMessage("Loading..."); dialog.setProgress(0); dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); dialog.setMax(maxValue); dialog.show(); } @Override protected void onPostExecute(Void result) { super.onPostExecute(result); if (this.dialog.isShowing()) { this.dialog.dismiss(); } this.callback.onThreadFinish(); } } And in my activity, I do: final String page = htmlPage.substring(start, end).trim(); //Create new instance of the AsyncTask.. new UIThreadProgress(this, new UIThreadCallback() { @Override public void run() { row_id = makeTableRow(row_id, layout, params, matcher); //ADD a row to the table layout. } @Override public void onThreadFinish() { System.out.println("FINISHED!!"); } @Override public boolean condition() { return matcher.find(); } }).execute(); So the above creates an async task to run to update a table layout activity while showing the progress bar that displays how much work has been done.. However, I get an error saying that only the thread that started the activity can update its views. I tried doing: MainActivity.this.runOnUiThread(new Runnable() { @Override public void run() { row_id = makeTableRow(row_id, layout, params, matcher); //ADD a row to the table layout. } } But this gives me synchronization errors.. Any ideas how I can display progress and at the same time update my table in the background? Currently my UI looks like:

  • Replace html element with data in javascript

    - by Ultimate
    I trying to auto increment the serial number when row increases and automatically readjust the numbering order when a row gets deleted in javascript. For that I am using the following clone method for doing my task. Rest of the thing is working correct except its not increasing the srno because its creating the clone of it. Following is my code for this: function addCloneRow(obj) { if(obj) { var tBody = obj.parentNode.parentNode.parentNode; var trTable = tBody.getElementsByTagName("tr")[1]; var trClone = trTable.cloneNode(true); if(trClone) { var txt = trClone.getElementsByTagName("input"); var srno = trClone.getElementsByTagName("span"); var dd = trClone.getElementsByTagName("select"); text = tBody.getElementsByTagName("tr").length; alert(text) //here i am getting the srno in increasing order //I tried something like following but not working //var ele = srno.replace(document.createElement("h1"), srno); //alert(ele); for(var i=0; i<dd.length; i++) { dd[i].options[0].selected=true; var nm = dd[i].name; var nNm = nm.substring((nm.indexOf("_")+1),nm.indexOf("[")); dd[i].name = nNm+"[]"; } for(var j=0; j<txt.length; j++) { var nm = txt[j].name; var nNm = nm.substring((nm.indexOf("_")+1),nm.indexOf("[")); txt[j].name = nNm+"[]"; if(txt[j].type == "hidden"){ txt[j].value = "0"; }else if(txt[j].type == "text") { txt[j].value = ""; }else if(txt[j].type == "checkbox") { txt[j].checked = false; } } for(var j=0; j<txt.length; j++) { var nm = txt[j].name; var nNm = nm.substring((nm.indexOf("_")+1),nm.indexOf("[")); txt[j].name = nNm+"[]"; if(txt[j].type == "hidden"){ txt[j].value = "0"; }else if(txt[j].type == "text") { txt[j].value = ""; }else if(txt[j].type == "checkbox") { txt[j].checked = false; } } tBody.insertBefore(trClone,tBody.childNodes[1]); } } } Following is my html : <table id="step_details" style="display:none;"> <tr> <th width="5">#</th> <th width="45%">Step details</th> <th>Expected Results</th> <th width="25">Execution</th> <th><img src="gui/themes/default/images/ico_add.gif" onclick="addCloneRow(this);"/></th> </tr> <tr> <td><span>1</span></td> <td><textArea name="step_details[]"></textArea></td> <td><textArea name="expected_results[]"></textArea></td> <td><select onchange="content_modified = true" name="exec_type[]"> <option selected="selected" value="1" label="Manual">Manual</option> <option value="2" label="Automated">Automated</option> </select> </td> <td><img src="gui/themes/default/images/ico_del.gif" onclick="removeCloneRow(this);"/></td> </tr> </table> I want to change the srno. of span element dynamically after increment and decrement on it.

  • Downsides to immutable objects in Java?

    - by parkr
    The advantages of immutable objects in Java seem clear: consistent state automatic thread safety simplicity You can favour immutability by using private final fields and constructor injection. But, what are the downsides to favouring immutable objects in Java? i.e. incompatibility with ORM or web presentation tools? Inflexible design? Implementation complexities? Is it possible to design a large-scale system (deep object graph) that predominately uses immutable objects?

  • Flickering Image in Java?

    - by Noah Cagle
    OK so I am coding a game right now to prepair for Ludum Dare SharkJam, and I am using a new method for programming, because the last method I had crashes my PC, so this one should work. Well it does work and all, better too, but the images that I put in it flicker. Here is the whole main class (where the images are drawn) package me.NoahCagle.watermaze; import java.awt.Color; import java.awt.Graphics; import java.awt.Image; import java.awt.image.BufferedImage; import javax.swing.JFrame; import me.NoahCagle.watermaze.entity.EntityShark; import me.NoahCagle.watermaze.entity.Player; import me.NoahCagle.watermaze.input.Keys; import me.NoahCagle.watermaze.map.Map; public class Game extends JFrame { private static final long serialVersionUID = 1L; Map map = new Map(0, 0); Player player = new Player(50, 30); static EntityShark shark = new EntityShark(400, 400); public Image dbImage; public Game() { setSize(800, 600); setDefaultCloseOperation(EXIT_ON_CLOSE); setLocationRelativeTo(null); setVisible(true); setTitle("Water Maze"); setResizable(false); setBackground(Color.blue); addKeyListener(new Keys()); } public static void main(String[] args) { new Game(); Thread s = new Thread(shark); s.start(); } public void paint(Graphics g) { dbImage = new BufferedImage(getWidth(), getHeight(), BufferedImage.TYPE_INT_RGB); g.drawImage(dbImage, map.x, map.y, null); g.drawImage(player.player, player.x, player.y, this); g.drawImage(shark.shark, shark.x, shark.y, this); repaint(); } } What this code does for me is makes the Images work correctly, just flickering, alot. Can anyone help me with my issue? EDIT: I think it has something to do with where I call the repaint method in the paint method, so look there.

  • Displaying X11 Apps on Windows 7

    - by PatW
    I installed a product called xming, a light weight X11 server product on Windows 7 laptop. From remote RHEL system I redirected display to Win7 laptop then launched X11 GUI app. I was not able to launch X11 apps and have them appear on laptop display as intended. To fix it I added -ac to the properties of xming launch desktop icon. I been searching through Windows and xming docs but can't find explanation. My guess is it is like xhost + on unix that allows connections from anybody. Can anybody explain why this worked?

  • Kvpn on ubuntu 11.10 is stuck on 'Connecting'

    - by xupv5
    I recently installed open-vpn and it's gui, Kvpn, on my ubuntu system but after I load the configuration file and click 'Connect' it just runs through and gets stuck on 'Connecting', never actually getting connected. How do i get around this or what might i be doing wrong? The profile was set up using a .conf file and the network i'm trying to connect to needs only a username and password. I'm on a wi-fi connection, with one network card(also behind a university firewall, i suppose). Any help regarding connecting to a vpn on ubuntu would be much appreciated. Thanks!

  • Is it safe to make GL calls with multiple threads?

    - by user146780
    I was wondering if it was safe to make GL calls with multiple threads. Basically I'm using a GLUtesselator and was wondering if I could divide the objects to draw into 4 and assign a thread to each one. I'm just wondering if this would cause trouble since the tesselator uses callback functions. Can 2 threads run the same callback at the same time as long as that callback does not access ant global variables? Are there also other ways I could optimize OpenGL drawing using multithreading? Thanks

  • What's the best way to install software in Ubuntu?

    - by the0ther
    I'm new to Ubuntu and have been away from Linux for a while. I'm used to Windows and find this tedious on Linux but I want to give it a shot. My tendency is to prefer GUI tools over command-line, and Ubuntu is a distro that seems to cater to usability. I note it is based somewhat on apt-get which I've heard good things about. What's the best practise for installing apps on Ubuntu? Should I prefer to try my options in this order? Synaptic Package Manger apt-get on the command line .tar.gz files (old school)
