  • What is the fastest way to find duplicates in multiple BIG txt files?

    - by user2950750
    I am really in deep water here and I need a lifeline. I have 10 txt files. Each file has up to 100.000.000 lines of data. Each line is simply a number representing something else. Numbers go up to 9 digits. I need to (somehow) scan these 10 files and find the numbers that appear in all 10 files. And here comes the tricky part. I have to do it in less than 2 seconds. I am not a developer, so I need an explanation for dummies. I have done enough research to learn that hash tables and map reduce might be something that I can make use of. But can it really be used to make it this fast, or do I need more advanced solutions? I have also been thinking about cutting up the files into smaller files. To that 1 file with 100.000.000 lines is transformed into 100 files with 1.000.000 lines. But I do not know what is best: 10 files with 100 million lines or 1000 files with 1 million lines? When I try to open the 100 million line file, it takes forever. So I think, maybe, it is just too big to be used. But I don't know if you can write code that will scan it without opening. Speed is the most important factor in this, and I need to know if it can be done as fast as I need it, or if I have to store my data in another way, for example, in a database like mysql or something. Thank you in advance to anybody that can give some good feedback.

  • How hide some nodes in Richfaces Tree (do not render nodes by condition)?

    - by VestniK
    I have a tree of categories and courses in my SEAM application. Courses may be active and inactive. I want to be able to show only active or all courses in my tree. I've decided to always build complete tree in my PAGE scope component since building this tree is quite expensive operation. I have boolean flag courseActive in the data wrapped by TreeNode<T>. Now I can't find the way to show courses node only if this flag is true. The best result I've achieved with the following code: <h:outputLabel for="showInactiveCheckbox" value="show all courses: "/> <h:selectBooleanCheckbox id="showInactiveCheckbox" value="#{categoryTreeEditorModel.showAllCoursesInTree}"> <a4j:support event="onchange" reRender="categoryTree"/> </h:selectBooleanCheckbox> <rich:tree id="categoryTree" value="#{categoryTree}" var="item" switchType="ajax" ajaxSubmitSelection="true" reRender="categoryTree,controls" adviseNodeOpened="#{categoryTreeActions.adviseRootOpened}" nodeSelectListener="#{categoryTreeActions.processSelection}" nodeFace="#{item.typeName}"> <rich:treeNode type="Category" icon="..." iconLeaf="..."> <h:outputText value="#{item.title}"/> </rich:treeNode> <rich:treeNode type="Course" icon="..." iconLeaf="..." rendered="#{item.courseActive or categoryTreeEditorModel.showAllCoursesInTree}"> <h:outputText rendered="#{item.courseActive}" value="#{item.title}"/> <h:outputText rendered="#{not item.courseActive}" value="#{item.title}" style="color:#{a4jSkin.inactiveTextColor}"/> </rich:treeNode> </rich:tree> the only problem is if some node is not listed in any rich:treeNode it just still shown with title obtained by Object.toString() method insted of being hidden. Does anybody know how to not show some nodes in the Richfases tree according to some condition?

  • Creating and appending a big DOM with javascript - most optimized way?

    - by fenderplayer
    I use the following code to append a big dom on a mobile browser (webkit): 1. while(someIndex--) // someIndex ranges from 10 to possibly 1000 2. { 3. var html01 = ['<div class="test">', someVal,'</div>', 4. '<div><p>', someTxt.txt1, someTxt.txt2, '</p></div>', 5. // lots of html snippets interspersed with variables 6. // on average ~40 to 50 elements in this array 7. ].join(''); 8. var fragment = document.createDocumentFragment(), 9. div = fragment.appendChild(document.createElement('div')); 10. div.appendChild(jQuery(html01)[0]); 11. jQuery('#screen1').append(fragment); 12. } //end while loop 13. // similarly i create 'html02' till 'html15' to append in other screen divs Is there a better or faster way to do the above? Do you see any problems with the code? I am a little worried about line 10 where i wrap in jquery and then take it out.

    - by Farah fathiah
    I have a problem..I'm using visual studio 2008... I want to ask, how to get the xy coordinate of an image=(0,0) from in the Big box(div)??? because when the image is drag to the end of the box it will give me x=8 and y=8...instead of x=0 and y=0... Please help me!!! Tq... Here is the code: $('#dragThis').draggable({ cursor: 'move', // sets the cursor apperance containment: '#box', drag: function() { var offset = $(this).offset(); var xPos = Math.abs(offset.left); var yPos = Math.abs(offset.top); $('#posX').text('x: ' + xPos); $('#posY').text('y: ' + yPos); }, stop: function(event, ui) { // Show dropped position. var Stoppos = $(this).position(); var left = Math.abs(Stoppos.left); var top = Math.abs(Stoppos.top); $('#posX').text('left: ' + left); $('#posY').text('top: ' + top); } }); http://jsfiddle.net/qx5K7/

  • Override an IOCTL Handler in PQOAL

    - by Kate Moss' Big Fan
    When porting or creating a BSP to a new platform, we often need to make change to OEMIoControl or HAL IOCTL handler for more specific. Since Microsoft introduced PQOAL in CE 5.0 and more and more BSP today leverages PQOAL to simplify the OAL, we no longer define the OEMIoControl directly. It is somehow analogous to migrate from pure Windows SDK to MFC; people starts to define those MFC handlers and forgot the WinMain and the big message loop. If you ever take a look at the interface between OAL and Kernel, PUBLIC\COMMON\OAK\INC\oemglobal.h, the pfnOEMIoctl is still there just as the entry point of Windows Program is WinMain since day one. (For those may argue about pfnOEMIoctl is not OEMIoControl, I will encourage you to dig into PRIVATE\WINCEOS\COREOS\NK\OEMMAIN\oemglobal.c which initialized pfnOEMIoctl to OEMIoControl. The interface is just to split OAL and Kernel which no longer linked to one executable file in CE 6, all of the function signature is still identical) So let's trace into PQOAL to realize how it implements OEMIoControl and how can we override an IOCTL handler we interest. First thing to know is the entry point (just as finding the WinMain in MFC), OEMIoControl is defined in PLATFORM\COMMON\SRC\COMMON\IOCTL\ioctl.c. Basically, it does nothing special but scan a pre-defined IOCTL table, g_oalIoCtlTable, and then execute the handler. (The highlight part) Other than that is just for error handling and the use of critical section to serialize the function. BOOL OEMIoControl(     DWORD code, VOID *pInBuffer, DWORD inSize, VOID *pOutBuffer, DWORD outSize,     DWORD *pOutSize ) {     BOOL rc = FALSE;     UINT32 i; ...     // Search the IOCTL table for the requested code.     for (i = 0; g_oalIoCtlTable[i].pfnHandler != NULL; i++) {         if (g_oalIoCtlTable[i].code == code) break;     }     // Indicate unsupported code     if (g_oalIoCtlTable[i].pfnHandler == NULL) {         NKSetLastError(ERROR_NOT_SUPPORTED);         OALMSG(OAL_IOCTL, (             L"OEMIoControl: Unsupported Code 0x%x - device 0x%04x func %d\r\n",             code, code >> 16, (code >> 2)&0x0FFF         ));         goto cleanUp;     }            // Take critical section if required (after postinit & no flag)     if (         g_ioctlState.postInit &&         (g_oalIoCtlTable[i].flags & OAL_IOCTL_FLAG_NOCS) == 0     ) {         // Take critical section                    EnterCriticalSection(&g_ioctlState.cs);     }     // Execute the handler     rc = g_oalIoCtlTable[i].pfnHandler(         code, pInBuffer, inSize, pOutBuffer, outSize, pOutSize     );     // Release critical section if it was taken above     if (         g_ioctlState.postInit &&         (g_oalIoCtlTable[i].flags & OAL_IOCTL_FLAG_NOCS) == 0     ) {         // Release critical section                    LeaveCriticalSection(&g_ioctlState.cs);     } cleanUp:     OALMSG(OAL_IOCTL&&OAL_FUNC, (L"-OEMIoControl(rc = %d)\r\n", rc ));     return rc; }   Where is the g_oalIoCtlTable? It is defined in your BSP. Let's use DeviceEmulator BSP as an example. The PLATFORM\DEVICEEMULATOR\SRC\OAL\OALLIB\ioctl.c defines the table as const OAL_IOCTL_HANDLER g_oalIoCtlTable[] = { #include "ioctl_tab.h" }; And that leads to PLATFORM\DEVICEEMULATOR\SRC\INC\ioctl_tab.h which defined some of IOCTL handler but others are defined in oal_ioctl_tab.h which is under PLATFORM\COMMON\SRC\INC\. Finally, we got the full table body! (Just like tracing MFC, always jumping back and forth). The format of table is very straight forward, IOCTL code, Flags and Handler Function // IOCTL CODE,                          Flags   Handler Function //------------------------------------------------------------------------------ { IOCTL_HAL_INITREGISTRY,                   0,  OALIoCtlHalInitRegistry     }, { IOCTL_HAL_INIT_RTC,                       0,  OALIoCtlHalInitRTC          }, { IOCTL_HAL_REBOOT,                         0,  OALIoCtlHalReboot           }, The PQOAL scans through the table until it find a matched IOCTL code, then invokes the handler function. Since it scans the table from the top which means if we define TWO handler with same IOCTL code, the first one is always invoked with no exception. Now back to the PLATFORM\DEVICEEMULATOR\SRC\INC\ioctl_tab.h, with the following table { IOCTL_HAL_INITREGISTRY,                   0,  OALIoCtlDeviceEmulatorHalInitRegistry     }, ... #include <oal_ioctl_tab.h> Note the IOCTL_HAL_INITREGISTRY handler are defined in both BSP's local ioctl_tab.h and the common oal_ioctl_tab.h, but due to BSP's local handler comes before "#include <oal_ioctl_tab.h>" so we know the OALIoCtlDeviceEmulatorHalInitRegistry always get called. In this example, the DeviceEmulator BSP overrides the IOCTL_HAL_INITREGISTRY handler from OALIoCtlHalInitRegistry to OALIoCtlDeviceEmulatorHalInitRegistry by manipulating the g_oalIoCtlTable table. (In some point of view, it is similar to message map in MFC) Please be aware, when you override an IOCTL handler in PQOAL, you may want to clone the original implementation to your BSP and change to meet your need. It is recommended and save you the redundant works but remember to rename the handler function (Just like the DeviceEmulator it changes the name of OALIoCtlHalInitRegistry to OALIoCtlDeviceEmulatorHalInitRegistry). If you don't change the name, linker may not be happy (due to name conflict) and the more important is by using different handler name, you could always redirect the handler back to original one. (It is like the concept of OOP that calling a function in base class; still not so clear? I am goinf to show you soon!) The OALIoCtlDeviceEmulatorHalInitRegistry setups DeviceEmulator specific registry settings and in the end, if everything goes well, it calls the OALIoCtlHalInitRegistry (PLATFORM\COMMON\SRC\COMMON\IOCTL\reginit.c) to do the rest.     if(fOk) {         fOk = OALIoCtlHalInitRegistry(code, pInpBuffer, inpSize, pOutBuffer,             outSize, pOutSize);     } Now you got the picture, whenever you want to override an IOCTL hadnler that is implemented in PQOAL just Clone the handler function to your BSP as a template. Simple name change for the handler function, and a name change in the IOCTL table header file that maps the IOCTL with the function Implement your IOCTL handler and whenever you need to redirect it back just calling the original handler function. It is the standard way of implementing a custom IOCTL and most Microsoft developers prefer. The mapping of IOCTL routine to IOCTL code is platform specific - you control the header file that does that mapping.

  • What might cause the big overhead of making a HttpWebRequest call?

    - by Dimitri C.
    When I send/receive data using HttpWebRequest (on Silverlight, using the HTTP POST method) in small blocks, I measure the very small throughput of 500 bytes/s over a "localhost" connection. When sending the data in large blocks, I get 2 MB/s, which is some 5000 times faster. Does anyone know what could cause this incredibly big overhead? Update: I did the performance measurement on both Firefox 3.6 and Internet Explorer 7. Both showed similar results. Update: The Silverlight client-side code I use is essentially my own implementation of the WebClient class. The reason I wrote it is because I noticed the same performance problem with WebClient, and I thought that the HttpWebRequest would allow to tweak the performance issue. Regrettably, this did not work. The implementation is as follows: public class HttpCommChannel { public delegate void ResponseArrivedCallback(object requestContext, BinaryDataBuffer response); public HttpCommChannel(ResponseArrivedCallback responseArrivedCallback) { this.responseArrivedCallback = responseArrivedCallback; this.requestSentEvent = new ManualResetEvent(false); this.responseArrivedEvent = new ManualResetEvent(true); } public void MakeRequest(object requestContext, string url, BinaryDataBuffer requestPacket) { responseArrivedEvent.WaitOne(); responseArrivedEvent.Reset(); this.requestMsg = requestPacket; this.requestContext = requestContext; this.webRequest = WebRequest.Create(url) as HttpWebRequest; this.webRequest.AllowReadStreamBuffering = true; this.webRequest.ContentType = "text/plain"; this.webRequest.Method = "POST"; this.webRequest.BeginGetRequestStream(new AsyncCallback(this.GetRequestStreamCallback), null); this.requestSentEvent.WaitOne(); } void GetRequestStreamCallback(IAsyncResult asynchronousResult) { System.IO.Stream postStream = webRequest.EndGetRequestStream(asynchronousResult); postStream.Write(requestMsg.Data, 0, (int)requestMsg.Size); postStream.Close(); requestSentEvent.Set(); webRequest.BeginGetResponse(new AsyncCallback(this.GetResponseCallback), null); } void GetResponseCallback(IAsyncResult asynchronousResult) { HttpWebResponse response = (HttpWebResponse)webRequest.EndGetResponse(asynchronousResult); Stream streamResponse = response.GetResponseStream(); Dim.Ensure(streamResponse.CanRead); byte[] readData = new byte[streamResponse.Length]; Dim.Ensure(streamResponse.Read(readData, 0, (int)streamResponse.Length) == streamResponse.Length); streamResponse.Close(); response.Close(); webRequest = null; responseArrivedEvent.Set(); responseArrivedCallback(requestContext, new BinaryDataBuffer(readData)); } HttpWebRequest webRequest; ManualResetEvent requestSentEvent; BinaryDataBuffer requestMsg; object requestContext; ManualResetEvent responseArrivedEvent; ResponseArrivedCallback responseArrivedCallback; } I use this code to send data back and forth to an HTTP server.

    This is a homework question and I'm having a lot of trouble with it - I've managed to do some of it but still cant finish it - can i Please get some help. Q1. Bezier Curves The following example allows you to interactively control a bezier curve by dragging the control points Cubic.java Replace the call to draw the cubic shape (big.draw(cubic)), by your own function to draw a bezier by the recursive split method.

  • Silverlight for Everyone!!

    - by subodhnpushpak
    Someone asked me to compare Silverlight / HTML development. I realized that the question can be answered in many ways: Below is the high level comparison between a HTML /JavaScript client and Silverlight client and why silverlight was chosen over HTML / JavaScript client (based on type of users and major functionalities provided): 1. For end users Browser compatibility Silverlight is a plug-in and requires installation first. However, it does provides consistent look and feel across all browsers. For HTML / DHTML, there is a need to tweak JavaScript for each of the browser supported. In fact, tags like <span> and <div> works differently on different browser / version. So, HTML works on most of the systems but also requires lot of efforts coding-wise to adhere to all standards/ browsers / versions. Out of browser support No support in HTML. Third party tools like  Google gears offers some functionalities but there are lots of issues around platform and accessibility. Out of box support for out-of-browser support. provides features like drag and drop onto application surface. Cut and copy paste in HTML HTML is displayed in browser; which, in turn provides facilities for cut copy and paste. Silverlight (specially 4) provides rich features for cut-copy-paste along with full control over what can be cut copy pasted by end users and .advanced features like visual tree printing. Rich user experience HTML can provide some rich experience by use of some JavaScript libraries like JQuery. However, extensive use of JavaScript combined with various versions of browsers and the supported JavaScript makes the solution cumbersome. Silverlight is meant for RIA experience. User data storage on client end In HTML only small amount of data can be stored that too in cookies. In Silverlight large data may be stored, that too in secure way. This increases the response time. Post back In HTML / JavaScript the post back can be stopped by use of AJAX. Extensive use of AJAX can be a bottleneck as browser stack is used for the calls. Both look and feel and data travel over network.                           In Silverlight everything run the client side. Calls are made to server ONLY for data; which also reduces network traffic in long run. 2. For Developers Coding effort HTML / JavaScript can take considerable amount to code if features (requirements) are rich. For AJAX like interfaces; knowledge of third party kits like DOJO / Yahoo UI / JQuery is required which has steep learning curve. ASP .Net coding world revolves mostly along <table> tags for alignments whereas most popular tools provide <div> tags; which requires lots of tweaking. AJAX calls can be a bottlenecks for performance, if the calls are many. In Silverlight; coding is in C#, which is managed code. XAML is also very intuitive and Blend can be used to provide look and feel. Event handling is much clean than in JavaScript. Provides for many clean patterns like MVVM and composable application. Each call to server is asynchronous in silverlight. AJAX is in built into silverlight. Threading can be done at the client side itself to provide for better responsiveness; etc. Debugging Debugging in HTML / JavaScript is difficult. As JavaScript is interpreted; there is NO compile time error handling. Debugging in Silverlight is very helpful. As it is compiled; it provides rich features for both compile time and run time error handling. Multi -targeting browsers HTML / JavaScript have different rendering behaviours in different browsers / and their versions. JavaScript have to be written to sublime the differences in browser behaviours. Silverlight works exactly the same in all browsers and works on almost all popular browser. Multi-targeting desktop No support in HTML / JavaScript Silverlight is very close to WPF. Bot the platform may be easily targeted while maintaining the same source code. Rich toolkit HTML /JavaScript have limited toolkit as controls Silverlight provides a rich set of controls including graphs, audio, video, layout, etc. 3. For Architects Design Patterns Silverlight provides for patterns like MVVM (MVC) and rich (fat)  client architecture. This segregates the "separation of concern" very clearly. Client (silverlight) does what it is expected to do and server does what it is expected of. In HTML / JavaScript world most of the processing is done on the server side. Extensibility Silverlight provides great deal of extensibility as custom controls may be made. Extensibility is NOT restricted by browser but by the plug-in silverlight runs in. HTML / JavaScript works in a certain way and extensibility is generally done on the server side rather than client end. Client side is restricted by the limitations of the browser. Performance Silverlight provides localized storage which may be used for cached data storage. this reduces the response time. As processing can be done on client side itself; there is no need for server round trips. this decreases the round about time. Look and feel of the application is downloaded ONLY initially, afterwards ONLY data is fetched form the server. Security Silverlight is compiled code downloaded as .XAP; As compared to HTML / JavaScript, it provides more secure sandboxed approach. Cross - scripting is inherently prohibited in silverlight by default. If proper guidelines are followed silverlight provides much robust security mechanism as against HTML / JavaScript world. For example; knowing server Address in obfuscated JavaScript is easier than a compressed compiled obfuscated silverlight .XAP file. Some of these like (offline and Canvas support) will be available in HTML5. However, the timelines are not encouraging at all. According to Ian Hickson, editor of the HTML5 specification, the specification to reach the W3C Candidate Recommendation stage during 2012, and W3C Recommendation in the year 2022 or later. see http://en.wikipedia.org/wiki/HTML5 for details. The above is MY opinion. I will love to hear yours; do let me know via comments. Technorati Tags: Silverlight

  • Server-side DataTable Sorting in RichFaces

    - by sblundy
    I have a data table with a variable number of columns and a data scroller. How can I enable server side sorting? I prefer that it be fired by the user clicking the column header. <rich:datascroller for="instanceList" actionListener="#{pageDataModel.pageChange}"/> <rich:dataTable id="instanceList" rows="10" value="#{pageDataModel}" var="fieldValues" rowKeyVar="rowKey"> <rich:columns value="#{pageDataModel.columnNames}" var="column" index="idx"> <f:facet name="header"> <h:outputText value="#{column}"/> </f:facet> <h:outputText value="#{classFieldValues[idx]}" /> </rich:columns> </rich:dataTable> I already have a method on the bean for executing the sort. public void sort(int column)

  • Mouse over effect with jQuery in richfaces datatable and datascroller combo

    - by John
    Hi, I'm problem with defining a mouse over effect for my datatables. I have <a4j:form> <rich:dataTable id="dataTable"> ... </rich:dataTable> <rich:datascroller id="dataScroller" for="dataTable" /> </a4j:form> <rich:jQuery selector="#dataTable tr" query="mouseover(function(){jQuery(this).addClass('active-row')})"/> <rich:jQuery selector="#dataTable tr" query="mouseout(function(){jQuery(this).removeClass('active-row')})"/> which are working fine on the very first page. However if I use the datascroller to goto another page, the mouseover effect is gone. I've tried reRendering the table or the jQuery components, that didn't help with the problem at all. Any suggestion on how I can get this working? Thanks!

  • How to pass an input value from a small form into a big form? (PHP, Javascript, URLs)

    - by sarahdopp
    I have a Wordpress website that needs to display a 3rd party newsletter signup form. This sign-up form has lots of fields and takes up its own full page. I want to display a simple "enter email address, hit submit" form at the top of every page. When the user hits submit, it should take them to the full form, where their email address is already pre-populated in the appropriate field. What's a good way to pass the input value from the short form to the long form? I'm inclined to use the URL somehow, but I've never approached it before. (My skills: expert XHTML/CSS. competent with WP theme hacking. comfortable enough with PHP and Javascript to move things around, but not enough to write them from scratch.) Thanks!

  • Big smart ViewModels, dumb Views, and any model, the best MVVM approach?

    - by Edward Tanguay
    The following code is a refactoring of my previous MVVM approach (Fat Models, skinny ViewModels and dumb Views, the best MVVM approach?) in which I moved the logic and INotifyPropertyChanged implementation from the model back up into the ViewModel. This makes more sense, since as was pointed out, you often you have to use models that you either can't change or don't want to change and so your MVVM approach should be able to work with any model class as it happens to exist. This example still allows you to view the live data from your model in design mode in Visual Studio and Expression Blend which I think is significant since you could have a mock data store that the designer connects to which has e.g. the smallest and largest strings that the UI can possibly encounter so that he can adjust the design based on those extremes. Questions: I'm a bit surprised that I even have to "put a timer" in my ViewModel since it seems like that is a function of INotifyPropertyChanged, it seems redundant, but it was the only way I could get the XAML UI to constantly (once per second) reflect the state of my model. So it would be interesting to hear anyone who may have taken this approach if you encountered any disadvantages down the road, e.g. with threading or performance. The following code will work if you just copy the XAML and code behind into a new WPF project. XAML: <Window x:Class="TestMvvm73892.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:TestMvvm73892" Title="Window1" Height="300" Width="300"> <Window.Resources> <ObjectDataProvider x:Key="DataSourceCustomer" ObjectType="{x:Type local:CustomerViewModel}" MethodName="GetCustomerViewModel"/> </Window.Resources> <DockPanel DataContext="{StaticResource DataSourceCustomer}"> <StackPanel DockPanel.Dock="Top" Orientation="Horizontal"> <TextBlock Text="{Binding Path=FirstName}"/> <TextBlock Text=" "/> <TextBlock Text="{Binding Path=LastName}"/> </StackPanel> <StackPanel DockPanel.Dock="Top" Orientation="Horizontal"> <TextBlock Text="{Binding Path=TimeOfMostRecentActivity}"/> </StackPanel> </DockPanel> </Window> Code Behind: using System; using System.Windows; using System.ComponentModel; using System.Threading; namespace TestMvvm73892 { public partial class Window1 : Window { public Window1() { InitializeComponent(); } } //view model public class CustomerViewModel : INotifyPropertyChanged { private string _firstName; private string _lastName; private DateTime _timeOfMostRecentActivity; private Timer _timer; public string FirstName { get { return _firstName; } set { _firstName = value; this.RaisePropertyChanged("FirstName"); } } public string LastName { get { return _lastName; } set { _lastName = value; this.RaisePropertyChanged("LastName"); } } public DateTime TimeOfMostRecentActivity { get { return _timeOfMostRecentActivity; } set { _timeOfMostRecentActivity = value; this.RaisePropertyChanged("TimeOfMostRecentActivity"); } } public CustomerViewModel() { _timer = new Timer(CheckForChangesInModel, null, 0, 1000); } private void CheckForChangesInModel(object state) { Customer currentCustomer = CustomerViewModel.GetCurrentCustomer(); MapFieldsFromModeltoViewModel(currentCustomer, this); } public static CustomerViewModel GetCustomerViewModel() { CustomerViewModel customerViewModel = new CustomerViewModel(); Customer currentCustomer = CustomerViewModel.GetCurrentCustomer(); MapFieldsFromModeltoViewModel(currentCustomer, customerViewModel); return customerViewModel; } public static void MapFieldsFromModeltoViewModel(Customer model, CustomerViewModel viewModel) { viewModel.FirstName = model.FirstName; viewModel.LastName = model.LastName; viewModel.TimeOfMostRecentActivity = model.TimeOfMostRecentActivity; } public static Customer GetCurrentCustomer() { return Customer.GetCurrentCustomer(); } //INotifyPropertyChanged implementation public event PropertyChangedEventHandler PropertyChanged; private void RaisePropertyChanged(string property) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(property)); } } } //model public class Customer { public string FirstName { get; set; } public string LastName { get; set; } public DateTime TimeOfMostRecentActivity { get; set; } public static Customer GetCurrentCustomer() { return new Customer { FirstName = "Jim", LastName = "Smith", TimeOfMostRecentActivity = DateTime.Now }; } } }

  • Build Your Own CE6 Kernel

    - by Kate Moss' Big Fan
    The Share Source Program in Windows CE provides many modules in %_WINCEROOT%\Private\ tree, and the kernel is one of them! Although it is not full source of kernel but it is good enough for tracing it, even tweak the kernel. Tracing the kernel and see how it works is lots of fun, but it is fascinated to modify and verify the change you made. So first comes first, where is the source of kernel? It's in your %_WINCEROOT%\private\winceos\COREOS\nk\ And next question will be "How do I build it?", Some of you may say just "build -c" there and it should be good. If you are the owner of kernel and got full source, that is definitely the right answer, but none of them are applied to our case though. So what should I do? Let's dig deeper into the coreos\nk folder, there are a couples of subfolder, CELOG, KDSTUB, KERNEL and etc. KERNEL\ is the main component of kernel.dll, in the other word, most of the modify to kernel is going to happen here. And the good thing is, you could "build -c" in %_WINCEROOT%\private\winceos\COREOS\nk\kernel\ with no error at all. But before doing that, remember to backup eveything you are going to modify, including the source and binaries; remember, this is not something belong to you, and if you didn't restore them back later, it could end up confuse the subsequence QFE updates! Here is the steps Backup the source code, I will suggest the whole %_WINCEROOT%\private\winceos\COREOS\nk\ Backup the binaries in common\oak\lib\, and again if you are not sure which files, backup the whole %_WINCEROOT%\common\oak\lib\ is the safest way. Do whatever modification you want in %_WINCEROOT%\private\winceos\COREOS\nk\kernel\ build -c in %_WINCEROOT%\private\winceos\COREOS\nk\kernel If everything went well so far, you should get a new nkmain.lib,nkmain.pdb, nkprmain.lib and nkprmain.pdb in %_WINCEROOT%\public\common\oak\lib\%_TGTCPU%\%WINCEDEBUG%\ Basically, you just rebuild your new kernel, the rest is to "blddemo clean -q" to have your new kernel SYSGEN'd and include in your OS Image. Or just "set WINCEREL=1" then "sysgen -p common nk nkprof" and "makeimg" if you can't wait another minutes for "blddemo clean -q" Tat sounds good, but some of you may not like the idea to alter any code in private folder, and not to mention how annoying to backup/restore files every time. Better idea? Yes, Microsoft provides a tool SYSGEN_CAPTURE (http://msdn.microsoft.com/en-us/library/ee504678.aspx for detail and usage) to creates Sources files for public drivers that you want to modify and build in your platform directory. In fact, not only public drivers, virtually anything in the %_WINCEROOT%\public\<project name>\cesysgen\makefile can be captured, and of course including kernel. So I am going to introduce a second way to build your own kernel by using SYSGEN_CAPTURE tool. Again the steps Create a folder in your BSP for building kernel, says %_TARGETPLATROOT%\SRC\Kernel. Use "SYSGEN_CAPTURE -p common nk" and then you will get a SOURCES.KERN, you could also "SYSGEN_CAPTURE -p common nkprof" to generate profiler enabled kernel. rename the SOURCE.KERN to SOURCES and copy one of the sample makefile into your kernel directory. For example the one in PRIVATE\WINCEOS\COREOS\NK\KERNEL\NKNORMAL. Copy the source files you want to modify from private\winceos\coreos\nk\kernel\ into your kernel directory. Modifying the SOURCES= macro to the source files you addes in step 4. For example, if you copied the vm.c, it is going to be SOURCES=vm.c Refer to the private\winceos\COREOS\nk\kernel\sources.inc and add macro defines and proper include path in your SOURCES file. "set WINCEREL=1", "build -c" in your kernel directory and "makeimg", voila! Here is an example for the MACROS you need to add in x86 Here are the macros for x86 CDEFINES=$(CDEFINES) -DIN_KERNEL -DWINCEMACRO -DKERN_CORE # Machine independent defines CDEFINES=$(CDEFINES) -DDBGSUPPORT _COREOSROOT=$(_WINCEROOT)\private\winceos\coreos INCLUDES=$(_COREOSROOT)\inc;$(_COREOSROOT)\nk\inc !IFDEF DP_SETTINGS CDEFINES=$(CDEFINES) -DDP_SETTINGS=$(DP_SETTINGS) !ENDIF ASM_SAFESEH=1 CDEFINES=$(CDEFINES) -Gs100000 -DENCODE_GS_COOKIE

  • Does mixing Quartz and OpenGL-ES cause big performance degrade??

    - by Eonil
    I have a plan to make a game using OpenGL for 3D world view, and CALayer(or UIView) for HUD UI. It's easy to imagine performance degrade from mixing them, but the document which mention this impact disappeared: http://developer.apple.com/iphone/library/technotes/tn2008/tn2230.html I cannot find the document on current version of SDK reference. And I got this document: http://gamesfromwithin.com/gdc-2010-the-best-of-both-worlds-using-uikit-with-opengl If you experienced about this, please let me know about performance impact on current SDK.

  • Software to simplify displaying build status on a big visible monitor for team?

    - by MikeJ
    I had a little bit of budget left at year end and I wanted to start a little skunk works project to display build status what everyone was working on (our team is aobut 10 folks all told). I am thinking to buy a 47" LCD HD TV and drive it from a small pc via a browser/.NET web application. I was going to build the software over the christmas break since we are closed for 2 weeks starting this Friday. I thought I would solicit advise/feedback on what other teams had done. a lot of the tools we use SVN, Mantis have RSS feeds that I was thinking to render. Is this the way to go ? Thanks for any feedback in advance.

  • Ruby: Is there a better way to iterate over multiple (big) files?

    - by zxcvbnm
    Here's what I'm doing (sorry for the variable names, I'm not using those in my code): File.open("out_file_1.txt", "w") do |out_1| File.open("out_file_2.txt", "w") do |out_2| File.open_and_process("in_file_1.txt", "r") do |in_1| File.open_and_process("in_file_2.txt", "r") do |in_2| while line_1 = in_1.gets do line_2 = in_2.gets #input files have the same number of lines #process data and output to files end end end end end The open_and_process method is just to open the file and close it once it's done. It's taken from the pickaxe book. Anyway, the main problem is that the code is nested too deeply. I can't load all the files' contents into memory, so I have to iterate line by line. Is there a better way to do this? Or at least prettify it?

  • how do i see if a big JSON object contains a value?

    - by Haroldo
    I'm using PHP to json encode a massive multi-dimensional array of events, so i get something like this: var ents = {"7":{"event_id":"7","nn":"The Whisky Drifters","nn_url":"the-whisky-drifters","venue":"The Grain Barge","date_num":"2010-06-11","date_txt":"Friday 11th June","gig_club":"1","sd":"A New Acoustic String Band...","ven_id":"44","art":0},"15":{"event_id":"15","nn":"Bass Kitchen","nn_url":"bass-kitchen","venue":"Timbuk2","date_num":"2010-06-11","date_txt":"Friday 11th June","gig_club":"2","sd":"Hexadecimal \/ DJ Derek \/ Id","ven_id":"21","art":1}, the first dimension is the id, see var ents = {"7":{ So its possible to get the ids without examining the nested objects... What's the fastest, most efficent way to check if my JSON contains an id?

  • What's the big difference between those two binary files?

    - by Lela Dax
    These are two files (contained in the tar.bz2) that were generated using a just-in-time compiler for a game engine. The generated code from ui-linux.bin is from a x86_64 gcc compiler and the ui-windows.bin from the same brand of compiler but targetting win x86_64 (mingw-w64). I've attempted to debug a problem that occurs only on the windows version and i stumbled upon what it seems to be different end-binary code. However, the input assembly code was virtually identical (only difference being pointer representations as int). (there's theoretically no winabi/unixabi conflict since that's taken care of by an attribute flag on certain declarations involved). Any idea what it might be that makes these two binary codes different? The C for the mini-compiler and base assembly producing it appears compatible at first glance. http://www0.org/vm/bins.tar.bz2

  • Android Performance Question : Many small apps or one big app?

    - by kunjaan
    I read this quote in one of the webpages: If you are writing a large application, consider dividing it into a suite of applications and services. Smaller applications load faster and use fewer resources. Making a suite of applications, content providers, and services makes your code more open to incorporation into other applications as described the "Use and be used" tip. Is this true? What is the thumb rule for the size of app?
