  • Novel fitness measure for evolutionary image matching simulation

    - by Nick Johnson
    I'm sure many people have already seen demos of using genetic algorithms to generate an image that matches a sample image. You start off with noise, and gradually it comes to resemble the target image more and more closely, until you have a more-or-less exact duplicate. All of the examples I've seen, however, use a fairly straightforward pixel-by-pixel comparison, resulting in a fairly predictable 'fade in' of the final image. What I'm looking for is something more novel: A fitness measure that comes closer to what we see as 'similar' than the naive approach. I don't have a specific result in mind - I'm just looking for something more 'interesting' than the default. Suggestions?

  • Why does Joomla debug show 446 queries logged and 446 legacy queries logged?

    - by Darye
    I have been called in to fix the performance of a Joomla site that was already setup. I look at the debug output and it shows the same queries twice, once for queries logged and again for legacy queries logged. My guess is that it is actually running the same queries twice make for just under 900 queries per page (hope I am wrong) The Legacy plugin is disabled, so Legacy mode is not on at all. The site uses VirtueMart as well (which BTW isn't working properly if the cache in the Global Config is turned on) Besides the fact that I don't think it should be running 446 queries anyway (sometimes even up to 650 per page ), has anyone every experienced this issue, and where would I look to fix this. Thanks

  • Hiding Row in DataGridView Very Slow

    - by Ed Schwehm
    I have a DataGridView in a Winforms app that has about 1000 rows (unbound) and 50 columns. Hiding a column takes a full 2 seconds. When I want to hide about half the rows, this becomes a problem. private void ShowRows(string match) { this.SuspendLayout(); foreach (DataGridViewRow row in uxMainList.Rows) { if (match == row.Cells["thisColumn"].Value.ToString())) { row.Visible = false; } else { row.Visible = true; } } this.ResumeLayout(); } I did some testing by adding by addingConsole.WriteLine(DateTime.Now)around the actions, androw.Visible = falseis definitely the slow bit. Am I missing something obvious, like setting IsReallySlow = false? Or do I have to go ahead and enable Virtual Mode and code up the necessary events?

  • perl escaping \n or \t

    - by Michael
    I need to escape \n so on output I really get newline or tab $ perl -p -e 's/e/a/ge' now I want each e to be substituted with \n $ perl -p -e 's/e/\n/ge' but even \n gives me an error. this was a simplified example. In real script(makefile) I have substitute := perl -p -e 's/@([^@]+)@/defined $$ENV{$$1} ? $$ENV{$$1} : $$1/ge' and in target I have such a nice command $(substitute) $< > $@ and if the input file for perl contains \n at output I will see it literally... I want to have real newline.

  • Wordpress Template HTML CSS Layout Confusion

    I am having huge confusion with a template that I have purchased and I am trying to modify to handle a widget contact form.

  • Custom UITableViewCell not properly hiding views

    - by adamweeks
    I am using apple's custom table view cell code and modifying the drawRect code within the cell's view to look like I want it to. I've changed it to have some UILabels as well as a UIProgressView. If the data the cell is being built on doesn't have a certain field, I want the UIProgressView to be hidden. This works for a little while, but when a cell gets requeued, the progress view will start displaying again, even when I set it to hidden = YES. I've tried just not creating the ProgressView unless the data was there and that didn't work either. I thought the answer was in the [self setNeedsDisplay] but that doesn't seem to help. Here is the code for the progressview from drawRect that continues to be displayed: UIProgressView *c1Progress = [[UIProgressView alloc]initWithFrame:CGRectMake(20.0, 70.0, 280.0, 12.0)]; float iProgress = (value / target); c1Progress.progress = iProgress; if (!dataExists) { c1Progress.hidden = YES; } [self addSubview:criteria1Progress]; [c1Progress release];

  • asp.net mvc deployment

    - by Casey
    I've been dealing with a legacy asp.net 2.0 web site that was originally setup to deploy everything (source uncompiled) to the target server. I've been looking at doing some major upgrades and want to move to asp.net mvc. I'm coming from mostly a Java background where we typically deploy everything inside of a Web ARchive (war file) and the application server takes it from there. Is there a similar concept in the .net world? Right now in my mvc test app, I just put the compiled code into the deployed bin folder and the rest of the script/view files there as well. From what I have been reading it seems that most use the Publish feature of VS.

  • Why / When / How is this Android serviceBinder resetting to null?

    - by GaZ
    I've written a ListActivity for Android 2.1 which is used to display a list of event categories. As the user selects a category, the program calls a web service to retrieve a list of sub-events. For example, a top level event might be "soccer" and when the user selects this the web service would return various soccer associations (e.g. "english", "french", "german", etc.) and display them in a new list. The following code seems to work occasionally, however sometimes the call to the service (in EventsListTask) fails because the serviceBinder is null. How/Why does this happen? public class EventListsActivity extends ListActivity { private static final String EVENT_ID = "EventId"; private List<ListItem> eventList; private ArrayAdapter<ListItem> listItemArrayAdapter; private static final int LOADING_DIALOG = 1; private EventsListTask eventsListTask = null; private BFService serviceBinder; private ServiceConnection mConnection = new ServiceConnection() { public void onServiceConnected(ComponentName componentName, IBinder iBinder) { Log.i("EventListsActivity", "service connected"); serviceBinder = ((BFService.BFBinder)iBinder).getService(); } public void onServiceDisconnected(ComponentName componentName) { Log.i("EventListsActivity", "service disconnected"); serviceBinder = null; } }; @Override public void onCreate(Bundle savedInstanceState) { Log.i("EventListsActivity", "onCreate"); super.onCreate(savedInstanceState); setContentView(R.layout.list); eventList = new ArrayList<ListItem>(); listItemArrayAdapter = new ArrayAdapter<ListItem>(this, R.layout.row, eventList); setListAdapter(listItemArrayAdapter); Intent bindIntent = new Intent(this, BFService.class); bindService(bindIntent, mConnection, Context.BIND_AUTO_CREATE); int eventId = getIntent().getIntExtra(EVENT_ID, -1); if (eventsListTask == null || eventsListTask.getStatus() == AsyncTask.Status.FINISHED) { eventsListTask = new EventsListTask(); eventsListTask.execute(eventId); } } @Override protected void onDestroy() { Log.i("EventListsActivity", "destroyed"); super.onDestroy(); unbindService(mConnection); } @Override protected void onListItemClick(ListView listView, View view, int position, long id) { super.onListItemClick(listView, view, position, id); ListItem selectedItem = (ListItem) listView.getAdapter().getItem(position); Intent intent; if (selectedItem.getMarketType() != null) { intent = new Intent(this, MarketActivity.class); intent.putExtra(EVENT_ID, selectedItem.getId()); startActivityIfNeeded(intent, -1); } else if (selectedItem.getId() != -1) { intent = new Intent(this, EventListsActivity.class); intent.putExtra(EVENT_ID, selectedItem.getId()); startActivityIfNeeded(intent, -1); } else { Log.e("EventListsActivity", "unexpected item selected!"); } } @Override protected Dialog onCreateDialog(int id) { switch (id) { case (LOADING_DIALOG) : AlertDialog.Builder loadingDialog = new AlertDialog.Builder(this); loadingDialog.setTitle("Please Wait..."); loadingDialog.setMessage("Communicating with remote service."); return loadingDialog.create(); } return null; } private class EventsListTask extends AsyncTask<Integer, Void, LoginStatusEnum> { @Override protected void onPreExecute() { showDialog(LOADING_DIALOG); } @Override protected void onPostExecute(LoginStatusEnum loginStatusEnum) { dismissDialog(LOADING_DIALOG); if (loginStatusEnum != null) { switch (loginStatusEnum) { case OK: for (ListItem item : eventList) { listItemArrayAdapter.add(item); } listItemArrayAdapter.notifyDataSetChanged(); break; } } } @Override protected LoginStatusEnum doInBackground(Integer... params) { LoginStatusEnum result = LoginStatusEnum.OK; Integer eventId = params[0]; if (serviceBinder != null) { try { if (eventId == null || eventId == -1) { eventList = serviceBinder.getActiveEventTypes(); } else { eventList = serviceBinder.getEvents(eventId); } } catch (WebServiceException wse) { result = LoginStatusEnum.valueOf(wse.getMessage()); } } else { Log.e("EventListsActivity", "serviceBinder is null!"); } return result; } } } EDIT: The serviceBinder appears to be set to null when I reach the bottom of a list, when I change the target intent to go to a different activity: intent = new Intent(this, MarketActivity.class); intent.putExtra(EVENT_ID, selectedItem.getId()); startActivity(intent); This new activity also uses the same background service (binds in the same way, etc.). Is there anything I need to watch out for when doing this? Am I calling the target intent incorrectly? EDIT2: Here's the output from LogCat when I start the activity which calls the service (this time the service failed straight away!): 04-02 07:02:49.147: INFO/ActivityManager(61): Starting activity: Intent { cmp=net.foobar.activity/.EventListsActivity } 04-02 07:02:49.257: INFO/EventListsActivity(353): onCreate 04-02 07:02:49.426: INFO/EventListsActivity(353): service connected 04-02 07:02:49.437: ERROR/EventListsActivity(353): serviceBinder is null!

  • Facebook API friends_get is extremely slow

    - by IkimashoZ
    I have a PHP application running in iFrame mode. I am rendering an <fb:multi-friend-selector condensed="true"> inside of <fb:serverfbml> tags. This is inside a PHP file that calls a function that gets a list of user IDs using $facebook->api_client->friends_get();. The multi-friend selector renders just fine, but, when I leave the friend_get() call uncommented, the page takes between 15-20 seconds to load (confirmed with Firebug)! The goal is to limit the number of users displayed in the selector by building a list of user ids not to display, for use in the friend selector's exclude_ids parameter. And since it's "exclude_ids" and not "include_ids", I can't think of a way of getting around this api call. It seems to me there must be something I can do to make the api call faster, because I've seen friend selectors that load much more quickly.

  • .NET 4.0 project reference 2.0 assembly

    - by jamone
    I have a project in which I'd like to use some of the .NET 4.0 features but a core requirement is that I can use the System.Data.SQLite framework which is compiled against 2.X. I see mention of this being possible such as the accepted answer here but I don't see how to actually achieve this. When I just try and run my 4.0 project while referencing the 2.X assembly I get: Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information. What "additional configuration" is necessary?

  • Why doesn't Visual Studio show an exception message when my exception occurs in a static constructor

    - by Tim Goodman
    I'm running this C# code in Visual Studio in debug mode: public class MyHandlerFactory : IHttpHandlerFactory { private static Dictionary<string, bool> myDictionary = new Dictionary<string, bool>(); static MyHandlerFactory() { myDictionary.Add("someKey",true); myDictionary.Add("someKey",true); // fails due to duplicate key } } Outside of the static constructor, when I get to the line with the error Visual Studio highlights it and pops up a message about the exception. But in the static constructor I get no such message. I am stepping through line-by-line, so I know that I'm getting to that line and no further. Why is this? (I have no idea if that fact that my class implements IHttpHandlerFactory matters, but I included it just in case.) This is VS2005, .Net 2.0

  • How do I get Java to use the serial port in Linux?

    - by Phillip Gibb
    We make use of a java application that manages a pinpad via the serial port. This works perfectly on windows with the Sun Comm.jar, the supplied dll and the properties file. Now we are attempting to use this solution on Linux (actually it does run on various other flavours of linux out in the field) - with Ubuntu server mode. After much attempts - blood, sweat and almost tears we have this scenario: Java version 1.4.2_17 Linux - Ubuntu Comm libs - Comm3 supplied by sun with the default driver specified An external comm test shows the comm ports: /dev/ttyS0 and /dev/ttyS1 But the java application says unable to open port /dev/ttyS1 (using the RXRT files produces invalid port errors) Has anyone been able to use java 1.4.2 on linux for serial port communication and found a solution that I could apply in my scenario? greatly appreciated Phill

  • Does "Debug" invalidate ASP.Net MVC OutputCache?

    - by William Edmondson
    I have images stored in a database and am serving them from an MVC controller as "FileResult". If I run the MVC application from Visual Studio 2008 in debug mode and set a break point inside the controller method the debugger intercepts the call on every page refresh regardless of my "OutputCache" settings. Does the VS debugger invalidate the OutputCache or is there something else going on here? [OutputCache(Duration = 86400, VaryByParam = "id")] public FileResult Index(string id) { byte[] image; int imageId; int.TryParse(id, out imageId); using (var ctx = new EPEntities()) { var imageObj = (from images in ctx.Images where images.ID == imageId select images).FirstOrDefault(); image = imageObj.Image; } return new FileContentResult(image, "image/gif"); }

  • "return false" is ignored in certain browsers for link added dynamically to the DOM with JavaScript

    - by AlexV
    I dynamically add an <a> (link) tag to the DOM with: var link = document.createElement('a'); link.href = 'http://www.google.com/'; link.onclick = function () { window.open(this.href); return false; }; link.appendChild(document.createTextNode('Google')); //someDomNode.appendChild(link); I want the link to open in a new window (I know it's bad, but it's required) and I don't want to use the target attribute. My code works well in IE and Firefox, but the return false don't work in Safari, Chrome and Opera. By don't work I mean the link is followed after the new window is opened.

  • SQL Server 2008 database mirroring madness

    - by Dmitri Nesteruk
    I'm trying to get database mirroring to work on SQL Server 2008 between two computers. I checked connectivity, but here's what I end up with: on the principal machine, the server can connect to the mirror but refuses to set up a mirroring partnership due to it being 'unable to connect' (I checked connectivity, everything works). The weird thing has happened on the mirror. First, the mirror now thinks it's being mirrored. Second, after I delete and recover the mirrored database, it goes into Restoring... mode and just gets stuck there. Any ideas you might have on this are appreciated. Thanks!

  • Mercurial Pull Error

    - by Tyler
    I am new to the dvcs world. My company uses perforce and I'm not a fan so I thought I'd try to use mercurial as a front end. I set it up on a windows machine with TortiseHG, enabled the Perfarce extension, did a small checkout (limiting the target revision) and pulled for the rest. This seemed to be more robust than clone alone. This seems to be working fairly well as I've been able to get up to change 8700 or so. My problem is with an error in the perforce repo. During the hg pull command it hits an error abort: file path/to/file.pl missing in p4 workspace and rolls back the transaction. Is there anyway to bypass or skip that file and force it to continue since this is not a file I care about.

  • having issue while making the client calls persession in c# wcf

    - by krishna555
    1.) I have a main method Processing, which takes string as an arguments and that string contains some x number of tasks. 2.) I have another method Status, which keeps track of first method by using two variables TotalTests and CurrentTest. which will be modified every time with in a loop in first method(Processing). 3.) When more than one client makes a call parallely to my web service to call the Processing method by passing a string, which has different tasks will take more time to process. so in the mean while clients will be using a second thread to call the Status method in the webservice to get the status of the first method. 4.) when point number 3 is being done all the clients are supposed to get the variables(TotalTests,CurrentTest) parallely with out being mixed up with other client requests. 5.) The code that i have provided below is getting mixed up variables results for all the clients when i make them as static. If i remove static for the variables then clients are just getting all 0's for these 2 variables and i am unable to fix it. Please take a look at the below code. [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)] public class Service1 : IService1 { public int TotalTests = 0; public int CurrentTest = 0; public string Processing(string OriginalXmlString) { XmlDocument XmlDoc = new XmlDocument(); XmlDoc.LoadXml(OriginalXmlString); this.TotalTests = XmlDoc.GetElementsByTagName("TestScenario").Count; //finding the count of total test scenarios in the given xml string this.CurrentTest = 0; while(i<10) { ++this.CurrentTest; i++; } } public string Status() { return (this.TotalTests + ";" + this.CurrentTest); } } server configuration <wsHttpBinding> <binding name="WSHttpBinding_IService1" closeTimeout="00:10:00" openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="true" /> <security mode="Message"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" algorithmSuite="Default" establishSecurityContext="true" /> </security> </binding> </wsHttpBinding> client configuration <wsHttpBinding> <binding name="WSHttpBinding_IService1" closeTimeout="00:10:00" openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="true" /> <security mode="Message"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" algorithmSuite="Default" establishSecurityContext="true" /> </security> </binding> </wsHttpBinding> Below mentioned is my client code class Program { static void Main(string[] args) { Program prog = new Program(); Thread JavaClientCallThread = new Thread(new ThreadStart(prog.ClientCallThreadRun)); Thread JavaStatusCallThread = new Thread(new ThreadStart(prog.StatusCallThreadRun)); JavaClientCallThread.Start(); JavaStatusCallThread.Start(); } public void ClientCallThreadRun() { XmlDocument doc = new XmlDocument(); doc.Load(@"D:\t72CalculateReasonableWithdrawal_Input.xml"); bool error = false; Service1Client Client = new Service1Client(); string temp = Client.Processing(doc.OuterXml, ref error); } public void StatusCallThreadRun() { int i = 0; Service1Client Client = new Service1Client(); string temp; while (i < 10) { temp = Client.Status(); Thread.Sleep(1500); Console.WriteLine("TotalTestScenarios;CurrentTestCase = {0}", temp); i++; } } } Can any one please help.

  • How do I support the touch of the navigation bar label?

    - by iaefai
    I have an editor that I am making, and I need a way of editing the document's title. I was considering touching the title of the navigation item and have a custom view appear. I did this in an initial version of the application with a button bar item (and target/action), but I cannot seem to find a way to do it with the managed navigation bar. The alternative I was considering was putting another bar at the bottom with an item to do just that, but it doesn't seem like the best design if I don't need to do it, as it takes away from viewing space.

  • How to be sure that my MVC project is runting on the correct version after upgrade to vs2010?

    - by Stephane
    I just installed visual studio 2010 and upgraded my MVC project (which was running on MVC RC2 in visual studio 2008). visual studio 2010 updated every project file to target the framework 4.0. But the system.web.dll is pointing to C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 2\Assemblies\System.Web.Mvc.dll in VS2010 object browser, I have every dll showing up in multiple versions as expected (3.5.0.0 and 4.0.0.0) except for the System.Web.Mvc dll which doesn't show any version and points to the path I mentioned above. Isn't this namespace point to the Framework folder like the System.Web namespace? C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\System.Web.dll

  • .NET Thread Pool - Unresponsive WinForms UI

    - by Goober
    Scenario I have a Windows Forms Application. Inside the main form there is a loop that iterates around 3000 times, Creating a new instance of a class on a new thread to perform some calculations. Bearing in mind that this setup uses a Thread Pool, the UI does stay responsive when there are only around 100 iterations of this loop (100 Assets to process). But as soon as this number begins to increase heavily, the UI locks up into eggtimer mode and the thus the log that is writing out to the listbox on the form becomes unreadable. Question Am I right in thinking that the best way around this is to use a Background Worker? And is the UI locking up because even though I'm using lots of different threads (for speed), the UI itself is not on its own separate thread? Suggested Implementations greatly appreciated.

  • Subview position issue after UIOrientation (rotation) change

    - by asadqamber
    I have a viewController and have added a subview in it programatically. secondView.autoresizingMask = UIViewAutoresizingFlexibleWidth; [self.view addSubview:secondView]; I guess when the device rotates, my mainViewController knows that orientation changed, but the subview (secondView) inside the mainViewController does not know this, so I change its frame to landscape size in willRotateToInterfaceOrientation. secondView.frame = CGRectMake(0, 0, 480 , 260); This does not set in the correct position, it's 11 px below the NavigationBar. Why does it start from 11 px below the navigation bar? The navigation bar shrinks when we move from portrait to landscape mode and its because of this that my subview is 11px below.

  • Android.mk - How to assemble and link ARM assembler files

    - by Kim
    Hi, I have some *.cpp source files and some *.s ARM assembler files I want to assemble and link in my Android.mk file (by running ndk-build script). My Android.mk file looks like this: LOCAL_PATH:= $(call my-dir) include $(CLEAR_VARS) LOCAL_ARM_MODE := arm LOCAL_MODULE := libTestJNI LOCAL_SRC_FILES := Test.cpp TestAS_gas4.s LOCAL_CFLAGS := -DHAVE_CONFIG_H -DFPM_ARM -ffast-math -O3 -DOPT_ARM LOCAL_LDLIBS += -llog include $(BUILD_SHARED_LIBRARY) Unfortunately the .s file is not recognized. ndk-build says: Gdbserver : [arm-linux-androideabi-4.4.3] libs/armeabi/gdbserver Gdbsetup : libs/armeabi/gdb.setup make: ** No rule to make target /cygdrive/c/projects/TestAS_gas4.s', needed by/cygdrive/c/projects/obj/local/armeabi/objs-debug/libTestJNI/TestAS_gas4.o'. Stop. In a "normal" makefile I would have to assemble by using "as" in a rule. How is it done in the Android.mk files? /Kim

  • Using DLL that using COM in C#

    - by chekalin-v
    I have been writing DLL on C++, that will be use in C#. DLL have some function, where I call hres = CoInitializeEx(NULL, COINIT_MULTITHREADED); and next call hres = CoInitializeSecurity( NULL, -1, // COM authentication NULL, // Authentication services NULL, // Reserved RPC_C_AUTHN_LEVEL_PKT, // Default authentication RPC_C_IMP_LEVEL_IMPERSONATE, // Default Impersonation NULL, // Authentication info EOAC_NONE, // Additional capabilities NULL // Reserved ); There are no error then I trying to use this dll in C++. But if I call function from DLL via C# application I see Error (80010106) Cannot change thread mode after it is set. I changed hres = CoInitializeEx(NULL, COINIT_MULTITHREADED); to hres = CoInitialize(NULL); After this changes error appear after CoInitializeSecurity: (80010119) Security must be initialized before any interfaces are marshalled or unmarshalled. It cannot be changed once initialized. How resolve this trouble?

  • Force jQuery to accept XHTML string as XML?

    - by MidnightLightning
    So, as part of a baseline OpenID implementation in Javascript, I'm fetching a remote page source through AJAX, and looking for the <link rel="openid.server" href="http://www.example.com" /> tag in the head. I'm using the jQuery javascript library for the AJAX request, but am unable to parse out the link tags. Several other online sources talk about using the usual jQuery selectors to grab tags from XML/XHTML sources, but it seems jQuery can only get content from the body of an HTML document, not the head (which is where the link tags are; $(response).find('link') returns null). So, I'd either need to get jQuery to force this document into XML mode or otherwise get at the head tags. Is there a way to force jQuery to parse the response of an AJAX query as XML, when it's in reality XHTML? Or do I need to fall back to regular expressions to get the link tags out?
