  • ask. help me to compare two array of integers and the order does not matter.

    - by stdnoit
    [Example] <1 2 3 4 = <3 1 2 4 <1 2 3 4 != <3 4 1 1 and ummm it is in java. cant use hashmap table or anything just pure without library. I know there are two ways. 1. sort them and compare the array index by index 2. use two for loops and compare the outer index with the inner index. ( i have been trying with this but still not working) for(int i = 0; i < n; i++) { for(int j = 0; j < n; j++) { if(a[i] != a[j] && j == n) return false; } } return true; anything wrong with the code ? thanks

  • How can I ask Hibernate to create an index on a foreign key (JoinColumn)?

    - by Kent Chen
    Hi, This is my model. class User{ @CollectionOfElements @JoinTable(name = "user_type", joinColumns = @JoinColumn(name = "user_id")) @Column(name = "type", nullable = false) private List<String> types = new ArrayList<String>(); } You can imagin there would be a table called "user_type", which has two columns, one is "user_id", the other is "type". And when I use hbm2ddl to generate the ddls, I can have this table, along with the foreign key constraint on "user_id". However, there is no index of this for this column. And I need this index. How can I let hibernate to generate this index for me? Thank you!

  • What do you do when a client ask for a feature which is a really bad idea?

    - by TAG
    Recently there was a SO question asking how to implement a feature which blocked users from copying text from a page in their browser. There were many negative comments on this feature, both because it's not practically possible to implement effectively and because it will interfere with the users' experience? What's a programmer to do in these sorts of situations in dealing with their clients or employers?

  • running adb via wifi on ubuntu 13.04

    - by Blaze Tama
    First, im new on linux so please bear with me. I have a rooted android phone and i was able to run the adb via wifi network on windows, where i just need to go to the adb's directory and type adb connect. However, i can't just do that in my ubuntu. Everytime i enter adb connect, the terminal always said that i dont have the adb and i must install it. When i check the ADT Bundle (I downloaded the bundled one from here), i can see the adb is there inside the platform-tools folder. I already tried to change the directory to the platform-tools and run the adb connect from there, but its still not working. Do i need to install the adb again via terminal? Or did i miss something? You may be wondering why dont i just download the adb (again) via terminal and do trial and error? The answer is because i dont have a good internet connection, so i want to avoid unnecessary downloads. Thanks for your time :D

  • How do i reinstall windows back on to linux without flashdrive or cd?

    - by user287536
    I know this is for ubuntu. but elementary os and ubuntu are really similar, so any answers or instructions will work on this os. plus the people here at ubuntu are alot better with these kind of problems. I've installed elementary os, and i am somewhat satisfied. However, many of the addons and applications i used to use are incompatible with linux and wine doesnt work with these apps that work with drivers and plugins. My recovery hp partition was replaced by the grub partition somehow. i dont' have a cd or a working flashdrive. i have found many links, but i dont understand the instructions to a full level. ive heard that you can create a partition, extract your windows iso there, and then boot from it. i have done the first 2 steps, but i dont know how to boot from a certain partition. i know how to with command prompt, but not with terminal and/or grub. Please help? im a noob in linux, ive only installed it for a month

  • How to make Ubuntu remember forever the password after the first time

    - by Luis Alvarado
    Is it possible to make Ubuntu remember the password for any program after the first time it asks. I get asked for the password for Synaptic, for making a usb bootable, for connecting to the wifi network, for opening gparted and even to go to the bathroom. Is there a way to just tell it to ask once forever or just tell it to not ask (Without going to root account. I want to keep using my own account)

  • Is there a way to tell Drupal not to cache a specific page?

  • Can anyone tell me why my XML writer is not writing attributes?

    - by user1632018
    I am writing a parsing tool to help me clean up a large VC++ project before I make .net bindings for it. I am using an XML writer to read an xml file and write out each element to a new file. If an element with a certain name is found, then it executes some code and writes an output value into the elements value. So far it is almost working, except for one thing: It is not copying the attributes. Can anyone tell me why this is happening? Here is a sample of what it is supposed to copy/modify(Includes the attributes): <?xml version="1.0" encoding="utf-8"?> <Project DefaultTargets="Build" ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <ItemGroup Label="ProjectConfigurations"> <ProjectConfiguration Include="Debug|Win32"> <Configuration>Debug</Configuration> <Platform>Win32</Platform> </ProjectConfiguration> <ProjectConfiguration Include="Release|Win32"> <Configuration>Release</Configuration> <Platform>Win32</Platform> </ProjectConfiguration> </ItemGroup> <PropertyGroup Label="Globals"> <ProjectGuid>{57900E99-A405-49F4-83B2-0254117D041B}</ProjectGuid> <Keyword>Win32Proj</Keyword> <RootNamespace>libproj</RootNamespace> </PropertyGroup> Here is the output I am getting(No Attributes): <?xml version="1.0" encoding="utf-8"?> <Project> <ItemGroup> <ProjectConfiguration> <Configuration>Debug</Configuration> <Platform>Win32</Platform> </ProjectConfiguration> <ProjectConfiguration> <Configuration>Release</Configuration> <Platform>Win32</Platform> </ProjectConfiguration> </ItemGroup> <PropertyGroup> <ProjectGuid>{57900E99-A405-49F4-83B2-0254117D041B}</ProjectGuid> <Keyword>Win32Proj</Keyword> <RootNamespace>libproj</RootNamespace> Here is my code currently. I have tried every way I can come up with to write the attributes. string baseDir = (textBox2.Text + "\\" + safeFileName); string vcName = Path.GetFileName(textBox1.Text); string vcProj = Path.Combine(baseDir, vcName); using (XmlReader reader = XmlReader.Create(textBox1.Text)) { XmlWriterSettings settings = new XmlWriterSettings(); settings.OmitXmlDeclaration = true; settings.ConformanceLevel = ConformanceLevel.Fragment; settings.Indent = true; settings.CloseOutput = false; using (XmlWriter writer = XmlWriter.Create(vcProj, settings)) { while (reader.Read()) { switch (reader.NodeType) { case XmlNodeType.Element: if (reader.Name == "ClInclude") { string include = reader.GetAttribute("Include"); string dirPath = Path.GetDirectoryName(textBox1.Text); Directory.SetCurrentDirectory(dirPath); string fullPath = Path.GetFullPath(include); //string dirPath = Path.GetDirectoryName(fullPath); copyFile(fullPath, 3); string filename = Path.GetFileName(fullPath); writer.WriteStartElement(reader.Name); writer.WriteAttributeString("Include", "include/" + filename); writer.WriteEndElement(); } else if (reader.Name == "ClCompile" && reader.HasAttributes) { string include = reader.GetAttribute("Include"); string dirPath = Path.GetDirectoryName(textBox1.Text); Directory.SetCurrentDirectory(dirPath); string fullPath = Path.GetFullPath(include); copyFile(fullPath, 2); string filename = Path.GetFileName(fullPath); writer.WriteStartElement(reader.Name); writer.WriteAttributeString("Include", "src/" + filename); writer.WriteEndElement(); } else { writer.WriteStartElement(reader.Name); } break; case XmlNodeType.Text: writer.WriteString(reader.Value); break; case XmlNodeType.XmlDeclaration: case XmlNodeType.ProcessingInstruction: writer.WriteProcessingInstruction(reader.Name, reader.Value); break; case XmlNodeType.Comment: writer.WriteComment(reader.Value); break; case XmlNodeType.Attribute: writer.WriteAttributes(reader, true); break; case XmlNodeType.EntityReference: writer.WriteEntityRef(reader.Value); break; case XmlNodeType.EndElement: writer.WriteFullEndElement(); break; } } } }

  • I have made two template classes,could any one tell me if these things are useful?

    - by soul
    Recently i made two template classes,according to the book "Modern C++ design". I think these classes are useful but no one in my company agree with me,so could any one tell me if these things are useful? The first one is a parameter wrapper,it can package function paramters to a single dynamic object.It looks like TypeList in "Modern C++ design". You can use it like this: some place of your code: int i = 7; bool b = true; double d = 3.3; CParam *p1 = CreateParam(b,i); CParam *p2 = CreateParam(i,b,d); other place of your code: int i = 0; bool b = false; double d = 0.0; GetParam(p1,b,i); GetParam(p2,i,b,d); The second one is a generic callback wrapper,it has some special point compare to other wrappers: 1.This template class has a dynamic base class,which let you use a single type object represent all wrapper objects. 2.It can wrap the callback together with it's parameters,you can excute the callback sometimes later with the parameters. You can use it like this: somewhere of your code: void Test1(int i) { } void Test2(bool b,int i) { } CallbackFunc * p1 = CreateCallback(Test1,3); CallbackFunc * p2 = CreateCallback(Test2,false,99); otherwhere of your code: p1->Excute(); p2->Excute(); Here is a part of the codes: parameter wrapper: class NullType; struct CParam { virtual ~CParam(){} }; template<class T1,class T2> struct CParam2 : public CParam { CParam2(T1 &t1,T2 &t2):v1(t1),v2(t2){} CParam2(){} T1 v1; T2 v2; }; template<class T1> struct CParam2<T1,NullType> : public CParam { CParam2(T1 &t1):v1(t1){} CParam2(){} T1 v1; }; template<class T1> CParam * CreateParam(T1 t1) { return (new CParam2<T1,NullType>(t1)); } template<class T1,class T2> CParam * CreateParam(T1 t1,T2 t2) { return (new CParam2<T1,T2>(t1,t2)); } template<class T1,class T2,class T3> CParam * CreateParam(T1 t1,T2 t2,T3 t3) { CParam2<T2,T3> t(t2,t3); return new CParam2<T1,CParam2<T2,T3> >(t1,t); } template<class T1> void GetParam(CParam *p,T1 &t1) { PARAM1(T1)* p2 = dynamic_cast<CParam2<T1,NullType>*>(p); t1 = p2->v1; } callback wrapper: #define PARAM1(T1) CParam2<T1,NullType> #define PARAM2(T1,T2) CParam2<T1,T2> #define PARAM3(T1,T2,T3) CParam2<T1,CParam2<T2,T3> > class CallbackFunc { public: virtual ~CallbackFunc(){} virtual void Excute(void){} }; template<class T> class CallbackFunc2 : public CallbackFunc { public: CallbackFunc2():m_b(false){} CallbackFunc2(T &t):m_t(t),m_b(true){} T m_t; bool m_b; }; template<class M,class T> class StaticCallbackFunc : public CallbackFunc2<T> { public: StaticCallbackFunc(M m):m_m(m){} StaticCallbackFunc(M m,T t):CallbackFunc2<T>(t),m_m(m){} virtual void Excute(void){assert(CallbackFunc2<T>::m_b);CallMethod(CallbackFunc2<T>::m_t);} private: template<class T1> void CallMethod(PARAM1(T1) &t){m_m(t.v1);} template<class T1,class T2> void CallMethod(PARAM2(T1,T2) &t){m_m(t.v1,t.v2);} template<class T1,class T2,class T3> void CallMethod(PARAM3(T1,T2,T3) &t){m_m(t.v1,t.v2.v1,t.v2.v2);} private: M m_m; }; template<class M> class StaticCallbackFunc<M,void> : public CallbackFunc { public: StaticCallbackFunc(M method):m_m(method){} virtual void Excute(void){m_m();} private: M m_m; }; template<class C,class M,class T> class MemberCallbackFunc : public CallbackFunc2<T> { public: MemberCallbackFunc(C *pC,M m):m_pC(pC),m_m(m){} MemberCallbackFunc(C *pC,M m,T t):CallbackFunc2<T>(t),m_pC(pC),m_m(m){} virtual void Excute(void){assert(CallbackFunc2<T>::m_b);CallMethod(CallbackFunc2<T>::m_t);} template<class T1> void CallMethod(PARAM1(T1) &t){(m_pC->*m_m)(t.v1);} template<class T1,class T2> void CallMethod(PARAM2(T1,T2) &t){(m_pC->*m_m)(t.v1,t.v2);} template<class T1,class T2,class T3> void CallMethod(PARAM3(T1,T2,T3) &t){(m_pC->*m_m)(t.v1,t.v2.v1,t.v2.v2);} private: C *m_pC; M m_m; }; template<class T1> CallbackFunc *CreateCallback(CallbackFunc *p,T1 t1) { CParam2<T1,NullType> t(t1); return new StaticCallbackFunc<CallbackFunc *,CParam2<T1,NullType> >(p,t); } template<class C,class T1> CallbackFunc *CreateCallback(C *pC,void(C::*pF)(T1),T1 t1) { CParam2<T1,NullType>t(t1); return new MemberCallbackFunc<C,void(C::*)(T1),CParam2<T1,NullType> >(pC,pF,t); } template<class T1> CParam2<T1,NullType> CreateCallbackParam(T1 t1) { return CParam2<T1,NullType>(t1); } template<class T1> void ExcuteCallback(CallbackFunc *p,T1 t1) { CallbackFunc2<CParam2<T1,NullType> > *p2 = dynamic_cast<CallbackFunc2<CParam2<T1,NullType> > *>(p); p2->m_t.v1 = t1; p2->m_b = true; p->Excute(); }

  • How do I know if my system is capable of playing 24bit/96kHz sound?

    - by Igor Zinov'yev
    Let me state for the record that I'm a total noob when it comes to Hi-Fi sound systems, but I am rather picky about the sound quality. Normally I listen to CD recordings ripped to FLAC in 16/44, but I have several albums that are also ripped from vinyls to FLAC in 24/96. But it seems that I can't tell the difference between 16-bit and 24-bit versions (except for some vinyl noises, of course). That can be due to several reasons: my equipment (onboard audio, monitor headphones) isn't good enough to make any difference, my system is not playing audio in 24-bit 96 kHz, I am physically unable to hear the difference. So here is my question, how do I tell if my system can play 24-bit sound with 96 or 192 kHz resolution? And if it can, how do I tell that it plays it instead of downsampling to 16-bit / 44 kHz? Also, what hardware (audio cards, amplifiers, etc.) would you recommend to play such recordings on Ubuntu?

  • Is this too much to ask for a game programming and developing enthusiast? Am I doing this wrong?

    - by I_Question_Things_Deeply
    I have been a computer-fanatic for almost a decade now. I've always loved and wondered how computers work, even from the purest, lowest hardware level to the very smallest pixel on the screen, and all the software around that. That seems to be my problem though ... as I try to write code (I'm pretty fluent at C++) I always sit there enormous amounts of time in front of a text-editor wondering how every line, statement, datum, function, etc. will correspond to every Assembly and machine instruction performed to do absolutely everything necessary for the kernel to allocate memory to run my compiled program, and all of the other hardware being used as well. For example ... I would write cout << "Before memory changed" << endl; and run the debugger to get the Assembly for this, and then try and reverse disassemble the Assembly to machine code based on my ISA, and then research every .dll, library file, linked library, linking process, linker source code of the program, the make file, the kernel I'm using's steps of processing this compilation, the hardware's part aside from the processor (e.g. video card, sound card, chipset, cache latency, byte-sized registers, calling convention use, DDR3 RAM and disk drive, filesystem functioning and so many other things). Am I going about programming wrong? I mean I feel I should know everything that goes on underneath English syntax on a computer program. But the problem is that the more I research every little thing the less I actually accomplish at all. I can never finish anything because of this mentality, yet I feel compelled to know everything... what should I do?

  • How can I tell if the "optimizeCompilations" option is working?

    - by Greg
    I've gone through the instructions found at http://blogs.msdn.com/davidebb/archive/2009/04/15/a-new-flag-to-optimize-asp-net-compilation-behavior.aspx, but I'm not sure if it's working. This is for a .NeET 3.5 SP1 project. When I add the attribute to my web.config, I get the warning The 'optimizeCompilations' attribute is not declared. Does this work for the ASP.NET Development Server? How can I test that it's working?

  • Ho can I tell when the background is touched on a UICollectionView?

    - by Mason Cloud
    I've tried subclassing UICollectionView and overriding touchesBegan:withEvent: and hitTest:WithEvent:, and both of those methods trigger when I touch a cell. However, if I touch the space between the cells, nothing happens at all. Here's what I've created: @interface WSImageGalleryCollectionView : UICollectionView @end ..and.. @implementation WSImageGalleryCollectionView - (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"Touches began"); [super touchesBegan:touches withEvent:event]; } - (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event { NSLog(@"Hit test reached"); return [super hitTest:point withEvent:event]; } @end

  • C# How can I tell if an IEnumerable is Mutable?

    - by Logan
    I want a method to update certain entries of an IEnumerable. I found that doing a foreach over the entries and updating the values failed as in the background I was cloning the collection. This was because my IEnumerable was backed by some LINQ-SQL queries. By changing the method to take a List I have changed this behavior, Lists are always mutable and hence the method changes the actual objects in the list. Rather than demand a List is passed is there a Mutable interface I can use? // Will not behave as consistently for all IEnumerables public void UpdateYesterday (IEnumerable<Job> jobs) { foreach (var job : jobs) { if (job.date == Yesterday) { job.done = true; } } }

  • Ext JS how to tell PagingToolbar to use parent Grid storage?

    - by Nazariy
    I'm trying to build application that use single config passed by server as non native JSON (can contain functions). Everything works fine so far but I'm curious why PagingToolbar does not have an option to use parent Grid store? I have tried to set store in my config like this, but without success: {... store:Ext.StoreMgr.lookup('unique_store_id') } Is there any way to do so without writing tons of javascript for each view defining store, grid and other items in my application or at least extend functionality of PaginationToolbar that use options from parent object? UPDATED, Here is short example of server response (minified) { "xtype":"viewport", "layout":"border", "renderTo":Ext.getBody(), "autoShow":true, "id":"mainFrame", "defaults":{"split":true,"useSplitTips":true}, "items":[ {"region":"center", "xtype":"panel", "layout":"fit", "id":"content-area", "items":{ "id":"manager-panel", "region":"center", "xtype":"tabpanel", "activeItem":0, "items":[ { "xtype":"grid", "id":"domain-grid", "title":"Manage Domains", "store":{ "xtype":"arraystore", "id":"domain-store", "fields":[...], "autoLoad":{"params":{"controller":"domain","view":"store"}}, "url":"index.php" }, "tbar":[...], "bbar":{ "xtype":"paging", "id":"domain-paging-toolbar", "store":Ext.StoreMgr.lookup('domain-store') }, "columns":[...], "selModel":new Ext.grid.RowSelectionModel({singleSelect:true}), "stripeRows":true, "height":350, "loadMask":true, "listeners":{ "cellclick":activateDisabledButtons } } ] }, } ] }

  • How Can I tell where log4net thinks it's getting it's config file from?

    Hi, I have the following log from the log4net debug log: log4net: DefaultRepositorySelector: repository [log4net-default-repository] already exists, using repository type [log4net.Repository.Hierarchy.Hierarchy] log4net: XmlConfigurator: configuring repository [log4net-default-repository] using file [log4net.config] watching for file updates log4net: XmlConfigurator: configuring repository [log4net-default-repository] using file [log4net.config] log4net: XmlConfigurator: configuring repository [log4net-default-repository] using stream log4net:ERROR XmlConfigurator: Error while loading XML configuration System.Xml.XmlException: ' ' is an unexpected token.

  • Is there a PHP refactoring tool to tell what functions are never called?

    - by ae
    I have a large codebase which has suffered many changes over the years. I would like to remove the functions that are no longer called or relevant. Is there a tool that will analysis the codebase and determine if a method is ever used? I'm also using phpunit/xdebug which reports which functions have not been run for the unit tests, however coverage is only at 55% and will require a massive amount of work to bring it up to 100% (I'm working on it!). Anything that was a command line tool would be extra good as I could hook it into hudson (CI).

  • Can I tell Castle Windsor to create a component in a separate AppDomain?

    - by Michael L Perry
    I've created a multi-threaded service that uses Castle Windsor to create components to run on separate threads. I Resolve an component by name with parameters for each thread. I'm running into concurrency problems with a 3rd party library used by the components. I suspect that isolating those components in separate AppDomains will resolve the problem. Is there a way to have Resolve create the component using a different AppDomain? private ActivityThread NewActivityThread(ActivityInstance activityInstance) { // Set up the creation arguments. System.Collections.IDictionary arguments = new Dictionary<string, string>(); activityInstance.Parameters.ForEach(p => arguments.Add(p.Name, p.Value)); // Get the activity handler from the container. IActivity activity = Program.Container.Resolve<IActivity>(activityInstance.Name, arguments); // Create a thread for the activity. ActivityThread thread = new ActivityThread(activity, activityInstance, _nextActivityID++); return thread; } public ActivityThread(IActivity activity, ActivityInstance instance, int id) { _activity = activity; _instance = instance; _id = id; } public void Start() { if (_thread == null) { // Create a new thread to run this activity. _thread = new Thread(delegate() { _activity.Run(); }); _thread.Name = _activity.ToString(); _thread.SetApartmentState(ApartmentState.STA); _thread.Start(); } }
