• print customized result in prolog

  - by Allan Jiang

  I am working on a simple prolog program. Here is my problem. Say I already have a fact fruit(apple). I want the program take a input like this ?- input([what,is,apple]). and output apple is a fruit and for input like ?-input([is,apple,a,fruit]) instead of default print true or false, I want the program print some better phrase like yes and no Can someone help me with this? My code part is below: input(Text) :- phrase(sentence(S), Text), perform(S). %... sentence(query(Q)) --> query(Q). query(Query) --> ['is', Thing, 'a', Category], { Query =.. [Category, Thing]}. % here it will print true/false, is there a way in prolog to have it print yes/no, %like in other language: if(q){write("yes")}else{write("no")} perform(query(Q)) :- Q.

• mkdir error in bash script

  - by Don

  Hi, The following is a fragment of a bash script that I'm running under cygwin on Windows: deployDir=/cygdrive/c/Temp/deploy timestamp=`date +%Y-%m-%d_%H:%M:%S` deployDir=${deployDir}/$timestamp if [ ! -d "$deployDir" ]; then echo "making dir $deployDir" mkdir -p $deploydir fi This produces output such as: making dir /cygdrive/c/Temp/deploy/2010-04-30_11:47:58 mkdir: missing operand Try `mkdir --help' for more information. However, if I type /cygdrive/c/Temp/deploy/2010-04-30_11:47:58 on the command-line it succeeds, why does the same command not work in the script? Thanks, Don

• Example of ==, equals and hashcode in java

  - by Abhishek Jain

  Given this: String s1= new String("abc"); String s2= new String("abc"); String s3 ="abc"; System.out.println(s1==s3); System.out.println(s1==s2); System.out.println(s1.equals(s2)); System.out.println(s1.equals(s3)); System.out.println(s1.hashCode()); System.out.println(s2.hashCode()); System.out.println(s3.hashCode()); Output is: false false true true 96354 96354 96354 Here == is giving false for each object but hashcode for each String object is same. Why is it so?

• Installing Ruby On Rails - Issues with gem (and no RVM)

  - by JXPheonix

  I'm having this issue whenever i run "gem install rails": usr/local/lib/ruby/1.9.1/yaml.rb:56:in `<top (required)>': It seems your ruby installation is missing psych (for YAML output). To eliminate this warning, please install libyaml and reinstall your ruby. ERROR: Loading command: install (LoadError) cannot load such file -- zlib ERROR: While executing gem ... (NameError) uninitialized constant Gem::Commands::InstallCommand Ruby and Rubygems were both installed from source. I've installed libyaml from source and from apt-get. I'm running ubuntu 12.04. I am NOT running RVM as far as I know (trying "rvm" returns "bla bla bla not installed apt-get". I'm pretty sure this speaks of 2 separate issues but I need solutions to both. Thanks.

• Adding ivars to NSManagedObject subclass

  - by The Crazy Chimp

  When I create an entity using core data then generate a subclass of NSManagedObject from it I get the following output (in the .h): @class Foo; @interface Foo : NSManagedObject @property (nonatomic, retain) NSString *name; @property (nonatomic, retain) NSSet *otherValues; @end However, in my .m file I want to make use of the name and otherValues values. Normally I would simply create a couple of ivars and then add the properties for them as I required. That way I can access them in my .m file easily. In this situation would it be acceptable to do this? Would adding ivars to the .h (for name and otherValues) cause any unusual behaviour in the persistance & retrieval of objects?

• Excel 2003 VSTO convert to PDF

  - by KClough

  I have an excel workbook vsto solution that needs to generate a pdf copy of one of its sheets as output. I have a license for abcdpdf .net and tried outputting to html, then using abcpdf to convert the html to pdf, but the excel html markup tries to emulate excel with all 4 worksheets with horrible markup. It also messes up the colors (silver background across entire workbook). Any suggestions? Here is the code I'm currently using to generate the html file: FileInfo excelDoc = new FileInfo(Globals.ThisWorkbook.Path + @"\Document.html"); Globals.Sheet2.SaveAs(excelDoc.FullName, Excel.XlFileFormat.xlHtml, missing, missing, false, false, Excel.XlSaveAsAccessMode.xlNoChange, missing, missing, missing); If I hack away some of the html header tags manually, I can get abcdpf to accept it, but the formatting is a bit off and this solution seems sub optimal. Thanks in advance.

• Ruby as a scripting language for web server

  - by Olivier Lalonde

  Is it possible to use Ruby as a scripting language with a HTTP server ? I'd like to be able to simply put some Ruby files in a web directory and be able to execute them from my browser - just like I did with PHP. I have absolutely nothing against frameworks such as RoR, but I was told that I should first learn Ruby and only then move on with higher level frameworks. Of course, I could write some Ruby scripts and run them in the console, but I would prefer getting the input/output from my browser :) Is that possible at all ? Otherwise, how hard would it be for me to build a quick and simple web framework ?

• C++ destructor seems to be called 'early'

  - by suicideducky

  Please see the "edit" section for the updated information. Sorry for yet another C++ dtor question... However I can't seem to find one exactly like mine as all the others are assigning to STL containers (that will delete objects itself) whereas mine is to an array of pointers. So I have the following code fragment #include<iostream> class Block{ public: int x, y, z; int type; Block(){ x=1; y=2; z=3; type=-1; } }; template <class T> class Octree{ T* children[8]; public: ~Octree(){ for( int i=0; i<8; i++){ std::cout << "del:" << i << std::endl; delete children[i]; } } Octree(){ for( int i=0; i<8; i++ ) children[i] = new T; } // place newchild in array at [i] void set_child(int i, T* newchild){ children[i] = newchild; } // return child at [i] T* get_child(int i){ return children[i]; } // place newchild at [i] and return the old [i] T* swap_child(int i, T* newchild){ T* p = children[i]; children[i] = newchild; return p; } }; int main(){ Octree< Octree<Block> > here; std::cout << "nothing seems to have broken" << std::endl; } Looking through the output I notice that the destructor is being called many times before I think it should (as Octree is still in scope), the end of the output also shows: del:0 del:0 del:1 del:2 del:3 Process returned -1073741819 (0xC0000005) execution time : 1.685 s Press any key to continue. For some reason the destructor is going through the same point in the loop twice (0) and then dying. All of this occures before the "nothing seems to have gone wrong" line which I expected before any dtor was called. Thanks in advance :) EDIT The code I posted has some things removed that I thought were unnecessary but after copying and compiling the code I pasted I no longer get the error. What I removed was other integer attributes of the code. Here is the origional: #include<iostream> class Block{ public: int x, y, z; int type; Block(){ x=1; y=2; z=3; type=-1; } Block(int xx, int yy, int zz, int ty){ x=xx; y=yy; z=zz; type=ty; } Block(int xx, int yy, int zz){ x=xx; y=yy; z=zz; type=0; } }; template <class T> class Octree{ int x, y, z; int size; T* children[8]; public: ~Octree(){ for( int i=0; i<8; i++){ std::cout << "del:" << i << std::endl; delete children[i]; } } Octree(int xx, int yy, int zz, int size){ x=xx; y=yy; z=zz; size=size; for( int i=0; i<8; i++ ) children[i] = new T; } Octree(){ Octree(0, 0, 0, 10); } // place newchild in array at [i] void set_child(int i, T* newchild){ children[i] = newchild; } // return child at [i] T* get_child(int i){ return children[i]; } // place newchild at [i] and return the old [i] T* swap_child(int i, T* newchild){ T* p = children[i]; children[i] = newchild; return p; } }; int main(){ Octree< Octree<Block> > here; std::cout << "nothing seems to have broken" << std::endl; } Also, as for the problems with set_child, get_child and swap_child leading to possible memory leaks this will be solved as a wrapper class will either use get before set or use swap to get the old child and write this out to disk before freeing the memory itself. I am glad that it is not my memory management failing but rather another error. I have not made a copy and/or assignment operator yet as I was just testing the block tree out, I will almost certainly make them all private very soon. This version spits out -1073741819. Thank you all for your suggestions and I apologise for highjacking my own thread :$

• Haskell Syntax: Parse Error On Input

  - by NuNu

  As part of a mini-haskell compiler that I'm writing, I have a function named app. What I want this function to do is take in these arguments epp (App e1 e2). The first step would be to evaluate e1 recursively (epp e1) and check if the output would be an error. If not then evaluate e2 and then call another function eppVals to evaluate the outputs of the calls on e1 and e2 which I defined as v1 and v2 respectively. epp (App e1 e2) | epp e1 /= Error = eppVals v1 v2 | otherwise = Error where v1 = epp e1 v2 = epp e2 <- parse error on input `=' Logically I believe what I have written so far works but I'm getting a parse error on input = where I stated above. Any idea why? My second try epp :: Exp -> Error Val epp (App e1 e2) = (eppVals v1 v2) where v1 = (epp e1) v2 = (epp e2) But now throws Couldn't match expected type Val with actual type Error Val

• Is it possible to share a masterpage between MVC and webforms?

  - by Craig Quillen

  I am adding MVC to a project that has MANY legacy webform pages. This works fine. However, I currently have a separate masterpage for MVC and for the webforms. The two master pages produce essentially identical output. I'd really like to kill the webforms one and just use the MVC master page with all my pages and stay DRY. Not being DRY has already bitten me a couple times when I forgot to change both. I tried doing the obvious way and just pointing the webform content page's MasterPage attribute at the MVC masterpage. This throws an error saying the MVC masters only work with MVC views. This seems like it would be a pretty common problem with mixed MVC and webform projects. My MVC master isn't doing anything with ViewData, so I don't see any reason the webforms couldn't use them.

• what the true nature of @ in Transct-SQL

  - by Richard77

  Hello, I reading some old ScottGu's blogs on Linq2SQL. Now I'm doing the SPROC part. I'd like to know what's the exact meaning of @variable. See this from ScottGu's Blog ALTER PROCEDURE dbo.GetCustomersDetails ( @customerID nchar(5), @companyName nvarchar(40) output ) AS SELECT @companyName = CompanyName FROM Customers WHERE CustomerID = @customerID SELECT * FROM Orders WHERE CustomerID = @customerID ORDER BY OrderID I'm kind of lost as, so far, I've though of anything preceded by a '@' as a placeholder for user input. But, in the example above, it looks like '@companyName' is used as a regular variable like in C# for instance (SELECT @companyName = ...). But, @companyName is not known yet. So, what the true nature a something preceded by a '@' like above? a vriable? a simple placeholder to accommodate user entered value? Thanks for helping

• Uploadify uploadSettings with scripData does not work

  - by kubilayeksioglu

  Hi everyone, I am sending a file to my Java Servlet via jQuery Uploadify, there are no problems while sending the actual file. But when I try to send some scriptData with file along, to process on Servlet it just does not send anything. Here is the JS code: $("button").click(function(){ $("#uploadify").uploadifySettings('scriptData', {'length':'0.2'}); $('#uploadify').uploadifyUpload(); }); $('#uploadify').uploadify({ 'uploader': 'assets/uploadify/uploadify.swf', 'script': 'upload', 'folder': '/uploads' }); And here is the Servlet code on the server side: out.println(res.getParameter("length")); Only output I get is null, while expecting "0.2". I just cannot get what's wrong and any kind of help will be appreciated. Thanks in advance.

• ServerControl randomly null

  - by Sascha

  Hi, I got a master page with a server control in it. Randomly the server control is inaccessible from codebehind. This doesn't happen on a specific action (eg a Button click or so). Currently I have no clue what this could be. I don't think it's output caching since this is not explcitly activated and the error happens far to seldom for that. But I'm going to disable caching in the master page explicitly with next deployment. Anyone an idea how to find more info to find what's happening? Or has someone had a similar error? Thanks. sa

• Problem extracting text from RSS feeds

  - by Gautam

  Hi, I am new to the world of Ruby and Rails. I have seen rails cast 190 and I just started playing with it. I used selector gadget to find out the CSS and XPath I have the following code.. require 'rubygems' require 'nokogiri' require 'open-uri' url = "http://www.telegraph.co.uk/sport/football/rss" doc = Nokogiri::HTML(open(url)) doc.xpath('//a').each do |paragraph| puts paragraph.text end When I extracted text from a normal HTML page with css, I could get the extracted text on the console. But when I try to do the same either with CSS or XPath for the RSS Feed for the following URL mentioned in the code above, I dont get any output. How do you extract text from RSS feeds?? I also have another silly question. Is there a way to extract text from 2 different feeds and display it on the console something like url1 = "http://www.telegraph.co.uk/sport/football/rss" url2 = "http://www.telegraph.co.uk/sport/cricket/rss" Looking forward for your help and suggestions Thank You Gautam

• iPhone switch statement using enum

  - by Boris

  I have defined an enum in a header file of a class : typedef enum{ RED = 0, BLUE, Green } Colors; - (void) switchTest:(Colors)testColor; and in the implementation file I have : - (void) switchTest:(Colors)testColor{ if(testColor == RED){ NSLog(@"Red selected"); } switch(testColor){ case RED: NSLog(@"Red selected again !"); break; default: NSLog(@"default selected"); break; } } My code compiles correctly without warrnings. When calling the switchTest method with RED, the output is : "Red selected" but once the first line of the switch runs, the application quits unexpectedly and without warrnings/errors. I don't mind using if/else syntax but I would like to understand my mistake.

• What happens to an ActiveX control (COleControl) after the call to OnDestroy() ?

  - by richj

  I have an ActiveX control written in C++ that runs in Internet Explorer 8. Most of the time (approx 90%) when the tab or browser containing the control is closed, there is an access violation like this: The thread 'Win32 Thread' (0x1bf0) has exited with code 0 (0x0). Unhandled exception at 0x77b3b9fd in iexplore.exe: 0xC0000005: Access violation reading location 0x65007408. The access violation occurs after the call to OnDestroy() but before the call to the control's destructor. The debug output says: No symbols are loaded for any call stack frame. The source code cannot be displayed. None of my code is present in the stacktrace, although perhaps the heap was corrupted at some earlier point during execution. What lifecycle events does an ActiveX control receive between the call to OnDestroy() and the control's destructor?
