  • Silverlight 4 wait/spinner control

    - by Keith
    I'd like to implement a spinner control (something along these lines) in Silverlight 4 to display during pending operations. There are several examples on the web for Silverlight 3 but I'm either unable to compile them into my project or they just flat out display nothing. In addition I'm unable to find any examples specific to Silverlight 4. Can someone please post a sample for Silverlight 4 or a link to one?

  • Use OpenGL ES to create an iPhone painting tool?

    - by Jeff
    Is it feasible to use OpenGL ES to create an iPhone raster graphics editor like SketchBook Mobile(http://usa.autodesk.com/adsk/servlet/pc/item?siteID=123112&id=13872203)? Any related reference(tutorial, sample) you can recommend? Why I try to use OpenGL ES? Because it's hardware accelerated and cross-platform. Thanks in advance!

  • Time issues on the Network -- How to find the Root Cause

    - by Jeff
    A number of application servers started erroring out in my domain. Troubleshooting led me to a missconfiguration of NTP. I fixed the issue, but I don't know how the issue arose in the first place. The only errors I can find are System Error: 1097 Source: useenv System Error: 1058 Source: useenv System Error: 1030 Source: useenv System Error: 1000 Source: mmc How else can I find out why NTP started acting up on my domain? Is there any troubleshooting steps to diagnose why my DC started pulling from a random timeserver with the wrong time? EDIT: Current issue actually remains: the two 2003 DCs are not syncing with the PDC (a 2k8 box). w32tm /resync -- The computer did not resync because no time data was available.

  • What free OS should I use on my VPS?

    - by earlz
    Hello, I looked a bit but didn't see any duplicate of this so my question is which free(open source) OS do you use on servers and why do you use that OS? Background I have a VPS at Linode. There is a broad range of options for which OS I can put on it including both 32 and 64bit OSs. I just use it to run my small blog and for hosting random files. It's very low traffic. I have been using 64bit Arch Linux on my VPS and though I love the OS for general usage, for a server the constant breakage is troublesome. So I'm considering trying something new and am looking for suggestions.

  • Need tutorials on Content providers in android

    - by Rahul Varma
    Hi folks, I am in desperate need of good tutorials on Content Providers in Android. I have been searching in the web for the tutorials but none could give me a clear idea on how content providers work. I'll be grateful if anyone can provide me with sample codes of the projects that implement content providers...

  • Why does my performance slow to a crawl I move methods into a base class?

    - by Juliet
    I'm writing different implementations of immutable binary trees in C#, and I wanted my trees to inherit some common methods from a base class. However, I find. I have lots of binary tree data structures to implement, and I wanted move some common methods into in a base binary tree class. Unfortunately, classes which derive from the base class are abysmally slow. Non-derived classes perform adequately. Here are two nearly identical implementations of an AVL tree to demonstrate: AvlTree: http://pastebin.com/V4WWUAyT DerivedAvlTree: http://pastebin.com/PussQDmN The two trees have the exact same code, but I've moved the DerivedAvlTree.Insert method in base class. Here's a test app: using System; using System.Collections.Generic; using System.Diagnostics; using System.Linq; using Juliet.Collections.Immutable; namespace ConsoleApplication1 { class Program { const int VALUE_COUNT = 5000; static void Main(string[] args) { var avlTreeTimes = TimeIt(TestAvlTree); var derivedAvlTreeTimes = TimeIt(TestDerivedAvlTree); Console.WriteLine("avlTreeTimes: {0}, derivedAvlTreeTimes: {1}", avlTreeTimes, derivedAvlTreeTimes); } static double TimeIt(Func<int, int> f) { var seeds = new int[] { 314159265, 271828183, 231406926, 141421356, 161803399, 266514414, 15485867, 122949829, 198491329, 42 }; var times = new List<double>(); foreach (int seed in seeds) { var sw = Stopwatch.StartNew(); f(seed); sw.Stop(); times.Add(sw.Elapsed.TotalMilliseconds); } // throwing away top and bottom results times.Sort(); times.RemoveAt(0); times.RemoveAt(times.Count - 1); return times.Average(); } static int TestAvlTree(int seed) { var rnd = new System.Random(seed); var avlTree = AvlTree<double>.Create((x, y) => x.CompareTo(y)); for (int i = 0; i < VALUE_COUNT; i++) { avlTree = avlTree.Insert(rnd.NextDouble()); } return avlTree.Count; } static int TestDerivedAvlTree(int seed) { var rnd = new System.Random(seed); var avlTree2 = DerivedAvlTree<double>.Create((x, y) => x.CompareTo(y)); for (int i = 0; i < VALUE_COUNT; i++) { avlTree2 = avlTree2.Insert(rnd.NextDouble()); } return avlTree2.Count; } } } AvlTree: inserts 5000 items in 121 ms DerivedAvlTree: inserts 5000 items in 2182 ms My profiler indicates that the program spends an inordinate amount of time in BaseBinaryTree.Insert. Anyone whose interested can see the EQATEC log file I've created with the code above (you'll need EQATEC profiler to make sense of file). I really want to use a common base class for all of my binary trees, but I can't do that if performance will suffer. What causes my DerivedAvlTree to perform so badly, and what can I do to fix it?

  • How would I duplicate the Rank function in a Sql Server Compact Edition SELECT statement?

    - by AMissico
    It doesn't look like SQL Server Compact Edition supports the RANK() function. (See Functions (SQL Server Compact Edition) at http://msdn.microsoft.com/en-us/library/ms174077(SQL.90).aspx). How would I duplicate the RANK() function in a SQL Server Compact Edition SELECT statement. (Please use Northwind.sdf for any sample select statements, as it is the only one I can open with SQL Server 2005 Management Studio.)

  • Rails Tutorial Chapter 4 2nd Ed. Title Helper not being called with out argument.

    - by SuddenlyAwakened
    I am running through the Rails Tutorial by Michael Hartl (Screen Cast). Ran into the and issue in chapter 4 on the title helper. I have been putting my own twist on the code as I go to make sure I understand it all. However on this one I it is very similar and I am not quite sure why it is acting the way it is. Here is the code: Application.html.erb <!DOCTYPE html> <html> <head> <%- Rails.logger.info("Testing: #{yield(:title)}") %> <title><%= full_title(yield(:title)) %></title> <%= stylesheet_link_tag "application", :media => "all" %> <%= javascript_include_tag "application" %> <%= csrf_meta_tags %> </head> <body> <%= yield %> </body> </html> Application_helper.rb module ApplicationHelper def full_title(page_title) full_title = "Ruby on Rails Tutorial App" full_title += " | #{page_title}" unless page_title.blank? end end Home.html.erb <h1><%= t(:sample_app) %></h1> <p> This is the home page for the <a href="http://railstutorial.org/">Ruby on Rails Tutorial</a> sample application </p> about.html.erb <% provide(:title, t(:about_us)) %> <h1><%= t(:about_us) %></h1> <p> The <a href="http://railstutorial.org/">Ruby on Rails Tutorial</a> is a project to make a book and screencast to teach web development with <a href="http://railstutorial.org/">Ruby on Rails</a>. This is the sample application for the tutorial. </p> What Happens: The code works fine when I set the provide method like on the about page. However when I do not it does not seem to even call the helper. I am assuming that because no title is passed back. Any ideas on what I am doing wrong? Thank you all for your help.

  • Server suddenly running out of entropy

    - by Creshal
    Since a reboot yesterday, one of our virtual servers (Debian Lenny, virtualized with Xen) is constantly running out of entropy, leading to timeouts etc. when trying to connect over SSH / TLS-enabled protocols. Is there any way to check which process(es) is(/are) eating up all the entropy? Edit: What I tried: Adding additional entropy sources: time_entropyd, rng-tools feeding urandom back into random, pseudorandom file accesses – netted about 1 MiB additional entropy per second, problems still persisted Checking for unusual activity via lsof, netstat and tcpdump – nothing. No noticeable load or anything Stopping daemons, restarting permanent sessions, rebooting the entire VM – no change in behaviour What in the end worked: Waiting. Since about yesterday noon, there are no connection problems anymore. Entropy is still somewhat low (128 Bytes peak), but TLS/SSH sessions have no noticeable delay anymore. I'm slowly switching our clients back to TLS (all five of them!), but I don't expect any change in behavior now.

  • Anybody know how to get podcasts sorted correctly on a Zune?

    - by Will
    If I could understand the logic behind it I could actually manage to get my stuff sorted correctly on the device. It doesn't matter how things are sorted on disk, or in the software itself. As items are added to the sync list they end up sorted in some weird manner which, quite frankly, brings out an anger in me that scares me. A primitive, misshapen and unthinking anger. Kind of like the lumpy guy in Altered States. Frankly, I'm afraid one day its going to burst forth and I will track down the entire Zune team and make them pay for their failures. Help me prevent this from happening. Help me understand what I need to do to ensure my podcasts end up in the order I wish them to be in, not some obscure random order that makes no sense.

  • md5sum of large files gives different results sometimes

    - by Emanuele
    I have an AMD quad core, 8 gb RAM, 1 SSD EXT2 (2 months old), 2 HDD EXT4, approximately 1 year old. I'm using Ubuntu 10.04 x86-64 and when I compute the md5sum of large files (9 GB) sometimes I get different values than the one stored on a reference file. Upon restarting and switching off the PC then I get the expected results no matter how many times I repeat it. But this is random. I've turn on ECC (the fastest possible settings) and the issue seems to be rarer, but I've run memtest86+ for 6+ hours without a glitch (and with ECC off!). Any idea? Should I update the BIOS of my motherboard (Asus EVO-something...don't remember it now)? I've tried all the rest apart this, but genuinely don't know what to do anymore... Any suggestion is appreciated!

  • Lock Windows keyboard and mouse but still display screen normally

    - by Stephen Lacy
    I'm using windows 7, I have a dual monitor display. It displays important information related to the business, I'd rather that random users that walk in can't just walk over to it and start using the computer with the same access rights as the user the monitoring software is running as. What I would like is if any time someone presses a button on the keyboard including alt-ctrl-delete all that would appear is a dialog asking for a password. Then I can click cancel and it will return to showing the data I want displayed. ClearLock doesn't work I tried it btw

  • Displaying a notification when bluetooth is disconnected - Android

    - by Ryan T
    I am trying to create a program that will display a notification to the user if a Blue tooth device suddenly comes out of range from my Android device. I currently have the following code but no notification is displayed. I was wondering if it was possible I shouldn't use ACTION_ACL_DISCONNECTED because I believe the bluetooth stack would be expecting packets that state a disconnect is requested. My requirements state that the bluetooth device will disconnect without warning. Thank you for any assistance! BluetoothNotification.java: //This is where the notification is created. import android.app.Activity; import android.app.Notification; import android.app.NotificationManager; import android.app.PendingIntent; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.app.Activity; import android.app.Notification; import android.app.NotificationManager; import android.app.PendingIntent; import android.content.Context; import android.content.Intent; import android.os.Bundle; public class BluetoothNotification extends Activity { public static final int NOTIFICATION_ID = 1; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); /** Define configuration for our notification */ int icon = R.drawable.logo; CharSequence tickerText = "This is a sample notification"; long when = System.currentTimeMillis(); Context context = getApplicationContext(); CharSequence contentTitle = "Sample notification"; CharSequence contentText = "This notification has been generated as a result of BT Disconnecting"; Intent notificationIntent = new Intent(this, BluetoothNotification.class); PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); /** Initialize the Notification using the above configuration */ final Notification notification = new Notification(icon, tickerText, when); notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); /** Retrieve reference from NotificationManager */ String ns = Context.NOTIFICATION_SERVICE; final NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); mNotificationManager.notify(NOTIFICATION_ID, notification); finish(); } } Snippet from OnCreate: //Located in Controls.java IntentFilter filter1 = new IntentFilter(BluetoothDevice.ACTION_ACL_DISCONNECTED); this.registerReceiver(mReceiver, filter1); Snippet from Controls.java: private final BroadcastReceiver mReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); if (BluetoothDevice.ACTION_ACL_DISCONNECTED.equals(action)) { //Device has disconnected NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); } } };

  • Changing Admin Site URL (actually port) - how?

    - by TomTom
    I have a new install of the band new SharePoint 2010. I use host header identified site collections for everything. By default the admin site is on a random port. I would like to move the admin site to port 80, for the server name. As all sites have coded names (for example "intranet", "projects") this would allow administration via the server name - which is easier as external access does not have to remember the port number. How do I do this? I already changed the default URL, but the site (application) is still wrongly mapped. I dont find anything to change the IIS settings in the admin site. I possibly just miss it - so can anyone point me in the right direction?
