  • Give me a practical use-case of Multi-set

    - by Calm Storm
    I would like to know a few practical use-cases (if they are not related/tied to any programming language it will be better).I can associate Sets, Lists and Maps to practical use cases. For example if you wanted a glossary of a book where terms that you want are listed alphabetically and a location/page number is the value, you would use the collection TreeMap(OrderedMap which is a Map) Somehow, I can't associate MultiSets with any "practical" usecase. Does someone know of any uses? http://en.wikipedia.org/wiki/Multiset does not tell me enough :) PS: If you guys think this should be community-wiki'ed it is okay. The only reason I did not do it was "There is a clear objective way to answer this question".

  • MySQL: updating a row and deleting the original in case it becomes a duplicate

    - by Silvio Donnini
    I have a simple table made up of two columns: col_A and col_B. The primary key is defined over both. I need to update some rows and assign to col_A values that may generate duplicates, for example: UPDATE `table` SET `col_A` = 66 WHERE `col_B` = 70 This statement sometimes yields a duplicate key error. I don't want to simply ignore the error with UPDATE IGNORE, because then the rows that generate the error would remain unchanged. Instead, I want them to be deleted when they would conflict with another row after they have been updated I'd like to write something like: UPDATE `table` SET `col_A` = 66 WHERE `col_B` = 70 ON DUPLICATE KEY REPLACE which unfortunately isn't legal in SQL, so I need help finding another way around. Also, I'm using PHP and could consider a hybrid solution (i.e. part query part php code), but keep in mind that I have to perform this updating operation many millions of times. thanks for your attention, Silvio Reminder: UPDATE's syntax has problems with joins with the same table that is being updated

  • An interesting case of delete and destructor (C++)

    - by Viet
    I have a piece of code where I can call destructor multiple times and access member functions even the destructor was called with member variables' values preserved. I was still able to access member functions after I called delete but the member variables were nullified (all to 0). And I can't double delete. Please kindly explain this. Thanks. #include <iostream> using namespace std; template <typename T> void destroy(T* ptr) { ptr->~T(); } class Testing { public: Testing() : test(20) { } ~Testing() { printf("Testing is being killed!\n"); } int getTest() const { return test; } private: int test; }; int main() { Testing *t = new Testing(); cout << "t->getTest() = " << t->getTest() << endl; destroy(t); cout << "t->getTest() = " << t->getTest() << endl; t->~Testing(); cout << "t->getTest() = " << t->getTest() << endl; delete t; cout << "t->getTest() = " << t->getTest() << endl; destroy(t); cout << "t->getTest() = " << t->getTest() << endl; t->~Testing(); cout << "t->getTest() = " << t->getTest() << endl; //delete t; // <======== Don't do it! Double free/delete! cout << "t->getTest() = " << t->getTest() << endl; return 0; }

  • File Upload in GWT in a Special Case

    - by Maksud
    I am doing a software for a document system. In this system when a user completes a document and want to save it, the document will be uploaded directly to server without the user action. This system uses COM/ActiveX to facilitate user using native editors. Ok, my problem is: suppose I have a file say d:/notepad.txt. Using classical method a user can browse the file and upload it. I can do that with apache commonio and GWT FormPanel and FileUpload. But if I know the filename (d:/notepad.txt), is there any way to upload the file directly to server without the user having to browse the file. I am currently doing this by the ActiveX componenet calling some HttpUpload methods with POST. But that does not maintain session. Thanks

  • Better exception for non-exhaustive patterns in case

    - by toofarsideways
    Is there a way to get GHCi to produce better exception messages when it finds at runtime that a call has produced value that does not match the function's pattern matching? It currently gives the line numbers of the function which produced the non-exhaustive pattern match which though helpful at times does require a round of debugging which at times I feel is doing the same set of things over and over. So before I tried to put together a solution I wanted to see if something else exists. An exception message that in addition to giving the line numbers shows what kind of call it attempted to make? Is this even possible?

  • What's the case when using software licensed under GPL or LGPL

    - by Johnas
    With everything legal and in line with the ethical questions in software development, is it allowed to use an open source product in my software that I charge a fee for when selling? Scenario: I've developed an PHP Content Management System (CMS) and use some Linux executables licensed under GPL or LGPL in my CMS to accomplish various tasks like image editing. I'm selling the CMS and also including the executables when I deliver the product. I do not edit the source code of the GPL software, just using it.

  • Case Insensitive URLs with mod_rewrite

    - by Paul Tarjan
    I'd like for any url that doesn't hit an existing file, to do a lookup on the other possible cases and see if those files exist, and if so, 302 to them. If that's not possible, then I'm ok with these compromises: Only check the lowercase version Only check the first path portion For example http://example.com/CoOl/PaTH/CaMELcaSE should redirect to http://example.com/cool/path/camelCase (assuming the latter exists). but of course a full solution is much more useful to me and others

  • How to check for case sensitive in hibernate criteria

    - by dhiraj
    0 vote down star I have used hibernate to fetch the login information from the mysql database. But the problem is that say for example the user name is 'dhiraj' in the database, now the login is successful by entering the user name, but it is also allowing to enter by taking the user name in uppercase also, e.g., 'DHIRAJ'. I want to restrict it to as it in the database. Can you tell me how to achieve that in hibernate?

  • Google Application Engine slow in case of Python...

    - by Aftershock
    hi, I am reading a "table" in Python in GAE that has 1000 rows and the program stops because the time limit is reached. (So it takes at least 20 seconds.)( Is that possible that GAE is that slow? Is there a way to fix that? Is this because I use free service and I do not pay for it? Thank you. The code itself is this: for u in userall: # userall has 1000 users for stockname in stocknamesall: # 4 stocks astock= stocksowned() astock.quantity = random.randint(1,100) astock.nameid = u.key() astock.stockid = stockname.key() liststocks.append(astock);

  • The case against Maven?

    - by Asgeir S. Nilsen
    Time and time again I've read and heard people frustrated over Maven and how complicated it is. And that it's much easier to use Ant to build code. However, in order to: Compile code Run tests Package a deployable unit This is all you need from Maven: <project> <modelVersion>4.0.0</modelVersion> <groupId>type something here</groupId> <artifactId>type something here</artifactId> <version>type something here</version> </project> What would be the corresponding minimal Ant build file?

  • "Special case" records for foreign key constraints

    - by keithjgrant
    Let's say I have a mysql table, called foo with a foreign key option_id constrained to the option table. When I create a foo record, the user may or may not have selected an option, and 'no option' is a viable selection. What is the best way to differentiate between 'null' (i.e. the user hasn't made a selection yet) and 'no option' (i.e. the user selected 'no option')? Right now, my plan is to insert a special record into the option table. Let's say that winds up with an id of 227 (this table already has a number of records at this point, so '1' isn't available). I have no need to access this record at a database level, and it would act as nothing more than a placeholder that the foreign key in the foo table can reference. So do I just hard-code '227' in my codebase when I'm creating 'foo' records where the user has selected 'no option'? The hard-coded id seems sloppy, and leaves room for error as the code is maintained down the road, but I'm not really sure of another approach.

  • Unit testing, mocking - simple case: Service - Repository

    - by rafek
    Consider a following chunk of service: public class ProductService : IProductService { private IProductRepository _productRepository; // Some initlization stuff public Product GetProduct(int id) { try { return _productRepository.GetProduct(id); } catch (Exception e) { // log, wrap then throw } } } Let's consider a simple unit test: [Test] public void GetProduct_return_the_same_product_as_getProduct_on_productRepository() { var product = EntityGenerator.Product(); _productRepositoryMock.Setup(pr => pr.GetProduct(product.Id)).Returns(product); Product returnedProduct = _productService.GetProduct(product.Id); Assert.AreEqual(product, returnedProduct); _productRepositoryMock.VerifyAll(); } At first it seems that this test is ok. But let's change our service method a little bit: public Product GetProduct(int id) { try { var product = _productRepository.GetProduct(id); product.Owner = "totallyDifferentOwner"; return product; } catch (Exception e) { // log, wrap then throw } } How to rewrite a given test that it'd pass with the first service method and fail with a second one? How do you handle this kind of simple scenarios? HINT: A given test is bad coz product and returnedProduct is actually the same reference.

  • How to roll back changes in gridview in case of incorrect input

    - by Mustafa A. Jabbar
    Hi, I have a DataGridView that is bound to a list of object. It has some columns that the user can edit. There are certain inputs that are not allowed for a row as a whole. How can I roll back if the user enters invalid inputs in some cell. I tried using the RowValidating event handler but it was not called after cell value has been changed. Even when I implemet CellValueChanged, I still cannot roll back the changes. Any idea how to accomplish this

  • Auto enter pass phrase in case of Python ssl Client/Server

    - by rauch
    I need to create Client/Server application to send files from clients to Server. I use simple ssl sockets for that and authenticate with certificates. ms = socket.socket(socket.AF_INET, socket.SOCK_STREAM) ssl_sock = ssl.wrap_socket(ms, keyfile=".../newCA/my_client.key", certfile=".../newCA/my_client.crt", server_side=0, cert_reqs=ssl.CERT_REQUIRED, ca_certs=".../newCA/CA/my-ca.crt" ) ssl_sock.connect((HOST, MPORT)) And Server side: msock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) self.ssl_sock = ssl.wrap_socket(msock, keyfile=".../newCA/my_server.key", certfile=".../newCA/my_server.crt", server_side=1, cert_reqs=ssl.CERT_REQUIRED, ca_certs=".../newCA/CA/my-ca.crt" ) self.ssl_sock.bind(('', self.PORT)) self.ssl_sock.listen(self.QUEUE_MAX) The problem is the following: when client tries to connect to Server, it requires Enter the pass phrase for private key for Both: for Server-side and Client-side. In Java we need to set System Property: javax.net.ssl.keyStorePassword="" and it has to be used automatically, But how is it been used in Python? I can't enter pass phrase all time the client connects.

  • The case of the sneaky backslash - Regex

    - by Shane Cusson
    I'm missing something very obvious here, but I just cant see it. I've got: string input = @"999\abc.txt"; string pattern = @"\\(.*)"; string output = Regex.Match(input,pattern).ToString(); Console.WriteLine(output); My result is: \abc.txt I don't want the slash and cant figure out why it's sneaking into the output. I tried flipping the pattern, and the slash winds up in the output again: string pattern = @"^(.*)\\"; and get: 999\ Strange. The result is fine in Osherove's Regulator. Any thoughts? Thanks.

  • How to create a generic list in this wierd case in c#

    - by Marc Bettex
    Hello, In my program, I have a class A which is extended by B, C and many more classes. I have a method GetInstance() which returns a instance of B or C (or of one of the other child), but I don't know which one, so the return type of the method is A. In the method CreateGenericList(), I have a variable v of type A, which is in fact either a B, a C or another child type and I want to create a generic list of the proper type, i.e. List<B> if v is a B or List<C> if v is a C, ... Currently I do it by using reflection, which works, but this is extremely slow. I wanted to know if there is another way to to it, which doesn't use reflection. Here is an example of the code of my problem: class A { } class B : A { } class C : A { } // More childs of A. class Program { static A GetInstance() { // returns an instance of B or C } static void CreateGenericList() { A v = Program.GetInstance(); IList genericList = // Here I want an instance of List<B> or List<C> or ... depending of the real type of v, not a List<A>. } } I tried the following hack. I call the following method, hoping the type inferencer will guess the type of model, but it doesn't work and return a List<A>. I believe that because c# is statically typed, T is resolved as A and not as the real type of model at runtime. static List<T> CreateGenericListFromModel<T>(T model) where T : A { return new List<T> (); } Does anybody have a solution to that problem that doesn't use reflection or that it is impossible to solve that problem without reflection? Thank you very much, Marc

  • Use case for output buffering as the correct solution to "headers already sent"

    - by kemp
    I see (not just on this site) a lot of question from inexperienced PHP programmers about the infamous "headers already sent... output started at" error, and many people suggest using ouput buffering as a solution. In my experience I have never found a situation where that error wasn't caused by a flow in the program's logic. Are there cases where output buffering is actually the correct solution?

  • jQuery DataLink - Does DataLink solve my use case?

    - by AnApprentice
    Hello, I recently heard of the jQuery datalink plugin and wondered if I should be using if for the following: I have a an inbox in my app that consists of the following: Inbox (index) - List of Items (list of mails) Inbox (show) Item Viewer (1 mail) Inbox Unread Counter The challenge I'm having now is a user can mark a mail as read/unread in either view which makes keeping the counter accurate challenging. Can datalink help with this? If so how? Also, I read that datalink requires forms is that true? Or can I bind the links to anything like 0 and anytime a mailitem changes from read to unread it would automatically update? Thanks

  • 302 vs 301 redirect in this specific case

    - by Binder
    We have a website that displays information in a location based manner, i.e. it detects the IP of the visiting user and redirects him/her to an appropriate landing page; for e.g. a user coming from 'Egypt' will be redirected to http://www.mysite.com/egypt/cairo and a user visting from dubai will be redirected to http://www.mysite.com/uae/dubai, so on and so forth and we cater to multiple locations in the middle-east. Now, we have been advised by our SEO consultant that we should put a 301 (permanent redirect) on http://www.mysite.com to point to http://www.mysite.com/ksa/riyadh I would like to know the negative implications that this would have on Google indexing or otherwise, as I fundamentally disagree with this suggestion and believe that in a siutation like this a 302 redirect would be more appropriate.
