• Is it a solvable problem to generate a regular expression that matches some input set?

  - by Roman

  I provide some input set which contains known separated number of text blocks. I want to make a program that automatically generate 1 or more regular expressions each of which matches every text block in the input set. I see some relatively easy ways to implement a brute-force search. But I'm not an expert in compilers theory. That's why I'm curious: 1) is this problem solvable? or there are some principle impossibility to make such algorithm? 2) is it possible to achieve polynomial complexity for this algorithm and avoid brute forcing?

• Strict pointer aliasing: any solution for a specific problem?

  - by doublep

  I have a problem caused by breaking strict pointer aliasing rule. I have a type T that comes from a template and some integral type Int of the same size (as with sizeof). My code essentially does the following: T x = some_other_t; if (*reinterpret_cast <Int*> (&x) == 0) ... Because T is some arbitary (other than the size restriction) type that could have a constructor, I cannot make a union of T and Int. (This is allowed only in C++0x only and isn't even supported by GCC yet). Is there any way I could rewrite the above pseudocode to preserve functionality and avoid breaking strict aliasing rule? Note that this is a template, I cannot control T or value of some_other_t; the assignment and subsequent comparison do happen inside the templated code. (For the record, the above code started breaking on GCC 4.5 if T contains any bit fields.)

• Is there any Inheritance problem with <table> and it's elements, like <form> elements?

  - by metal-gear-solid

  Is there any Inheritance problem with <table>, tr th td tbody thead tfoot also like form elements? In IE 6+ and FF 3+ with Strict doctype. Tables also have inheritance turned off in some browsers. You may notice that in some browsers, your tables’ text will be larger, clunkier and not so pretty. This is also due to inheritance. Many browsers give tables their own style. It's mentioned here http://www.komodomedia.com/blog/2006/10/css-trickery-part-5-inheritance/ For which browsers author is talking about, it's not mentioned I tested on FF 3.6 and IE7 but unable to find is there any issue. I just wanted to be sure before adding this in my CSS reset. Do i really need this? table { font-family:inherit; font-size:inherit; font-weight:inherit; }

• Jquery effect problem : How to detect if mouseover is triggered by scroll ?

  - by Crupuk

  Hello, I have another problem, and because the reply is to fast here i come back again !! I would like to use "key navigation" and for that, i use the keypress event with down/up key ) When my mouse is over a div (div who's contenaing a big table) and i pull the down key : i scroll to next td + change css style + remove the current style And again, for each event.. So, because my mouse is over the main div, each time i scroll (auto) to a element, the mouseover event is triggered .. And so, the effect is missed.. This is the perfect script : User use keyboard navigation : Mouseover is disabled (so style change only with up/down key) User don't use keyboard : mouseover change the style Could you help me ? The code : $("#content tr").mouseover(function() { $("#content tr.use,#content tr.sel").removeClass("use sel"); $(this).addClass("sel"); }); And the keyboard navigation code : http://pastebin.com/Hgn5Y1FV (Sorry again for my english.. ) Thanks

• Fluent NHibernate beginner problem: How to convert single column data to custom class?

  - by Stefan Ahlm

  I am very new to Fluent NHibernate and I have a problem that I cant find the answer to. I have a string column in my database table, containing a mathematical expression i.e: "10 + 15 * 5". On my entity I have a property that I call Formula and this returns a class that contains the mathematical "formula" (not as a string). I beleive this post http://intellect.dk/post/Implementing-custom-types-in-nHibernate.aspx explains how to solve it for NHibernate. But I am not sure... How do I get this working with Fluent NHibernate?

• is this a problem in the sp_rename function or sql server itself ?

  - by user81967

  While renaming the column name, the square bracket is included in the column name, which I think is a bug, Here is a sample code snippet, create table [TestTable] (TestColumnName nvarchar(30)) select TestColumnName from TestTable sp_rename '[TestTable].[TestColumnName]', '[RenamedColumnName]', 'Column' select [RenamedColumnName] from TestTable -- does not work "Invalid column name 'RenamedColumnName'." select RenamedColumnName from TestTable -- does not work "Invalid column name 'RenamedColumnName'." select * from [TestTable] -- works fine!!! The bug here is that the column rename includes the square brackets, I found this which says that the "first character must be one of the following", but "[" does not seem be included in the list, can there be a problem with sp_rename or sql server itself, as it allows alteration of column name to start with a square bracket.

• Problem with number/type of arguments passed to an overloaded c++ constructor wrapped with swig.

  - by MiKo

  I am trying to wrap a c++ class (let's call it "Spam") written by someone else with swig to expose it to Python. After solving several problems, I am able to import the module in python, but when I try to create an object of such class I obtain the following error: foo = Spam.Spam('abc',3) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "Spam.py", line 96, in __init__ this = _Spam.new_Spam(*args) NotImplementedError: Wrong number of arguments for overloaded function 'new_Spam'. Possible C/C++ prototypes are: Spam(unsigned char *,unsigned long,bool,unsigned int,SSTree::io_action,char const *) Spam(unsigned char *,unsigned long,bool,unsigned int,SSTree::io_action) Spam(unsigned char *,unsigned long,bool,unsigned int) Spam(unsigned char *,unsigned long,bool) Spam(unsigned char *,unsigned long) Googling around, I realized that the error is probably caused by the type of the arguments and not by the number (which is quite confusing), but I still cannot identify. I suspect the problem lies in passing a string as the first argument, but have no idea on how to fix it (keep in mind that I know almost no c/c++).

• Optimizing a Parking Lot Problem. What algorithims should I use to fit the most amount of cars in th

  - by Adam Gent

  What algorithms (brute force or not) would I use to put in as many cars (assume all cars are the same size) in a parking lot so that there is at least one exit (from the container) and a car cannot be blocked. Or can someone show me an example of this problem solved programmatically. The parking lot varies in shape would be nice but if you want to assume its some invariant shape that is fine. Another Edit: Assume that driving distance in the parking lot is not a factor (although it would be totally awesome if it was weighted factor to number of cars in lot). Another Edit: Assume 2 Dimensional (no cranes or driving over cars). Another Edit: You cannot move cars around once they are parked (its not a valet parking lot). I hope the question is specific enough now.

• Django Problem - trying to access data entered into a form and feed it through a different page

  - by John Hoke

  OK, so let me give you an overview first. I have this site and in it there is a form section. When you access that section you can view or start a new project. Each project has 3-5 different forms. My problem is that I don't want viewers to have to go through all 3-5 pages to see the relevant information they need. Instead I want to give each project a main page where all the essential data entered into the forms is shown as non-editable data. I hope this makes sense. So I need to find a way to access all that data from the different forms for each project and to feed that data into the new page I'll be calling "Main". Each project will have a separate main page for itself. I'm pretty much clueless as to how I should do this, so any help at all would be appreciated. Thanks

• How can I compute the average cost for this solution of the element uniqueness problem?

  - by Alceu Costa

  In the book Introduction to the Design & Analysis of Algorithms, the following solution is proposed to the element uniqueness problem: ALGORITHM UniqueElements(A[0 .. n-1]) // Determines whether all the elements in a given array are distinct // Input: An array A[0 .. n-1] // Output: Returns "true" if all the elements in A are distinct // and false otherwise. for i := 0 to n - 2 do for j := i + 1 to n - 1 do if A[i] = A[j] return false return true How can I compute the average cost (i.e. number of comparisons for a given n) for this algorithm? What is a reasonable assumption about the input?

• How to use TestAndSet() for solving the critical section problem?

  - by Dan Mantyla

  I'm studying for an exam and I'm having difficulty with a concept. This is the pseudo code I am given: int mutex = 0; do { while (TestAndSet(&mutex)); // critical section mutiex = 0; // remainder section } while (TRUE); My instructor says that only two of the three necessary conditions (mutual exclusion, progress, and bounded waiting) are met with this code, but I don't understand which one isn't being met...?? How should the code be modified to support the missing condition to solve the critical region problem? Thanks in advance for any insight!

• A problem with .NET 2.0 project, using a 3.0 DLL which implements WCF services.

  - by avance70

  I made a client for accessing my WCF services in one project, and all classes that work with services inherit from this class: public abstract class ServiceClient<TServiceClient> : IDisposable where TServiceClient : ICommunicationObject This class is where I do stuff like disposing, logging when the client was called, etc. some common stuff which all service classes would normally do. Everything worked fine, until I got the task to implement this on an old system. I got into a problem when I used this project (DLL) in an other project which cannot reference System.ServiceModel (since it's an old .NET 2.0 software that I still maintain, and upgrading it to 3.0 is out of the question). Here, if I omit where TServiceClient : ICommunicationObject then the project can build, but the ServiceClient cannot use, for example, client.Close() or client.State So, is my only solution to drop the where statement, and rewrite the service classes?

• Association in Entity Framework 4

  - by Marsharks

  I have two tables, a problem table and a problem history table. As you can expect, a problem can have many histories associated with it. CREATE TABLE [dbo].[Problem]( [Last_Update] [datetime] NULL, [Problem_Id] [int] NOT NULL, [Incident_Count] [int] NULL ) ALTER TABLE [dbo].[Problem] ADD CONSTRAINT [PK_Problem] PRIMARY KEY CLUSTERED ( [Problem_Id] ASC ) CREATE TABLE [dbo].[Problem_History]( [Last_Update] [datetime] NULL, [Problem_Id] [int] NOT NULL, [Severity_Chg_Flag] [char](1) NULL ) ALTER TABLE [dbo].[Problem_History] ADD [Create_DateTime] [datetime] NOT NULL ALTER TABLE [dbo].[Problem_History] WITH CHECK ADD CONSTRAINT [FK_Problem_History_Problem] FOREIGN KEY([Problem_Id]) REFERENCES [dbo].[Problem] ([Problem_Id]) The problem is when I drag this into an Entity Model, the associations are not included. Any ideas? I would like to point out that the problem history table has no separate key of its own, it shares the problem id

• problem with iOS 4.2 when user press the list view item to go to UIwebview page and the navigation button disappears on the second visit

  - by seahorse

  My app is a Navigation based application. The main menu contains the list view items. if I clicks one of them, it goes to next view which in this case take me to UIwebview embedded web site. Everything is looking great. I can view the content of web page, the navigation control back button which takes to the main menu if I press it. However, I'm having issue when I try to go back to main menu if i visit that subview the second time. It loads the content of UIwebview web page, but the navigation button is gone and won't let me go back to main menu. This problem only appears on latest iOS 4.2 version. Otherwise it works great on 3.1 to 4.1. I would appreciate any hints or inputs. Note this seems not working for subview using UIWebview embedded web content. I don't have any issue with other subviews

ORDER by id DESC "; $db->setQuery($query); $ingredients = $db->loadResult(); I cant understand how to tell the form to send chyrillic characters correct. Or where is the problem at all? How to fetch this characters correctly? Or how to send them correctly?

  The code below works fine, the problem is the 1st two lines are appearing on screen. It basically loads the PDF but I can't see the btnAcceptProposal change name or become enabled. Tried a Thread for the load but it broke.

• Drawing problem does ShowWindow(hWnd, SW_HIDE) automatically invalidate rectangles?

  - by wk1989

  Hello, I'm running into a problem where, I have a Window that contains a child window. The child window contains another child window where a video is playing using Windows Media Player. Whenever I do call ShowWindow (hWnd, SW_HIDE) on the parent Window and paint over the entire surface, the region occupied by the grand-child window (where the video was playing) is not overridden. I used spy++ and found that that region which was not overridden was set to hidden BEFORE the repaint occurs. I monitored the hwnd of the grand-child window and it did not seem to receive any WM_EraseBKGND or WM_NCPAINT messages. Does this mean the area it occupied had not been invalidated and therefore could not be drawn over? I'm new to winforms. Thanks!

• How is this problem usually solved without using sever-side scripting?

  - by cyggi

  Simple problem I have so far always solved via PHP: You have a site with header, menu, footer and content field. Header, menu and footer are usually the same for each page. How do you, without PHP or any other server-side language, have the header, menu and footer data exist only in one file? So that for example you don't have ten sites (like home.html, products.html, about.html, ..) all having a copy of the static header and menu in their html files. Now if you want to change the header you have to change ten files. I hope I made my question clear enough, if not please leave a comment :)
