  • Scala: Recursively building all pathes in a graph?

    - by DarqMoth
    Trying to build all existing paths for an udirected graph defined as a map of edges using the following algorithm: Start: with a given vertice A Find an edge (X.A, X.B) or (X.B, X.A), add this edge to path Find all edges Ys fpr which either (Y.C, Y.B) or (Y.B, Y.C) is true For each Ys: A=B, goto Start Providing edges are defined as the following map, where keys are tuples consisting of two vertices: val edges = Map( ("n1", "n2") -> "n1n2", ("n1", "n3") -> "n1n3", ("n3", "n4") -> "n3n4", ("n5", "n1") -> "n5n1", ("n5", "n4") -> "n5n4") As an output I need to get a list of ALL pathes where each path is a list of adjecent edges like this: val allPaths = List( List(("n1", "n2") -> "n1n2"), List(("n1", "n3") -> "n1n3", ("n3", "n4") -> "n3n4"), List(("n5", "n1") -> "n5n1"), List(("n5", "n4") -> "n5n4"), List(("n2", "n1") -> "n1n2", ("n1", "n3") -> "n1n3", ("n3", "n4") -> "n3n4", ("n5", "n4") -> "n5n4")) //... //... more pathes to go } Note: Edge XY = (x,y) - "xy" and YX = (y,x) - "yx" exist as one instance only, either as XY or YX So far I have managed to implement code that duplicates edges in the path, which is wrong and I can not find the error: object Graph2 { type Vertice = String type Edge = ((String, String), String) type Path = List[((String, String), String)] val edges = Map( //(("v1", "v2") , "v1v2"), (("v1", "v3") , "v1v3"), (("v3", "v4") , "v3v4") //(("v5", "v1") , "v5v1"), //(("v5", "v4") , "v5v4") ) def main(args: Array[String]): Unit = { val processedVerticies: Map[Vertice, Vertice] = Map() val processedEdges: Map[(Vertice, Vertice), (Vertice, Vertice)] = Map() val path: Path = List() println(buildPath(path, "v1", processedVerticies, processedEdges)) } /** * Builds path from connected by edges vertices starting from given vertice * Input: map of edges * Output: list of connected edges like: List(("n1", "n2") -> "n1n2"), List(("n1", "n3") -> "n1n3", ("n3", "n4") -> "n3n4"), List(("n5", "n1") -> "n5n1"), List(("n5", "n4") -> "n5n4"), List(("n2", "n1") -> "n1n2", ("n1", "n3") -> "n1n3", ("n3", "n4") -> "n3n4", ("n5", "n4") -> "n5n4")) */ def buildPath(path: Path, vertice: Vertice, processedVerticies: Map[Vertice, Vertice], processedEdges: Map[(Vertice, Vertice), (Vertice, Vertice)]): List[Path] = { println("V: " + vertice + " VM: " + processedVerticies + " EM: " + processedEdges) if (!processedVerticies.contains(vertice)) { val edges = children(vertice) println("Edges: " + edges) val x = edges.map(edge => { if (!processedEdges.contains(edge._1)) { addToPath(vertice, processedVerticies.++(Map(vertice -> vertice)), processedEdges, path, edge) } else { println("ALready have edge: "+edge+" Return path:"+path) path } }) val y = x.toList y } else { List(path) } } def addToPath( vertice: Vertice, processedVerticies: Map[Vertice, Vertice], processedEdges: Map[(Vertice, Vertice), (Vertice, Vertice)], path: Path, edge: Edge): Path = { val newPath: Path = path ::: List(edge) val key = edge._1 val nextVertice = neighbor(vertice, key) val x = buildPath (newPath, nextVertice, processedVerticies, processedEdges ++ (Map((vertice, nextVertice) -> (vertice, nextVertice))) ).flatten // need define buidPath type x } def children(vertice: Vertice) = { edges.filter(p => (p._1)._1 == vertice || (p._1)._2 == vertice) } def containsPair(x: (Vertice, Vertice), m: Map[(Vertice, Vertice), (Vertice, Vertice)]): Boolean = { m.contains((x._1, x._2)) || m.contains((x._2, x._1)) } def neighbor(vertice: String, key: (String, String)): String = key match { case (`vertice`, x) => x case (x, `vertice`) => x } } Running this results in: List(List(((v1,v3),v1v3), ((v1,v3),v1v3), ((v3,v4),v3v4))) Why is that?

  • Adding view cart function

    - by user228390
    Hey guys need some help in adding a view cart button but I'm stuck not sure how to code it. any help? The way I have coded it is that when a user clicks 'add item' they will get a alert box with info about the total price but I want that to appear in the HTML file but only once I have clicked on 'view cart' and I need it to be in a table format with info about the name, sum, price of the items and total. any ideas how I can do this? here is my javascript var f,d,str,items,qnts,price,bag,total; function cart(){ f=document.forms[0]; d=f.getElementsByTagName('div'); var items=[];var qnts=[];price=[];bag=[] for(i=0,e=0;i<d.length;i++){ items[i]=d[i].getElementsByTagName('b')[0].innerHTML; qnts[i]=d[i].getElementsByTagName('select')[0].value; str=d[i].getElementsByTagName('p')[1].innerHTML; priceStart(str,i); if(qnts[i]!=0){bag.push(new Array()); ib=bag[bag.length-1]; ib.push(items[i]);ib.push(qnts[i]);ib.push(price[i]);ib.push(qnts[i]*price[i]);} } if(bag.length>0){ total=bag[0][3]; if(bag.length>1){for(t=1;t<bag.length;t++){total+=bag[t][3]}} alert(bag.join('\n')+'\n----------------\ntotal='+total) } } function priceStart(str,inx){for(j=0;j<str.length;j++){if(str.charAt(j)!=' ' && !isNaN(str.charAt(j))){priceEnd(j,str,inx);return }}} function priceEnd(j,str,inx){for(k=str.length;k>j;k--){if(str.charAt(k)!=' ' && !isNaN(str.charAt(k))){price[inx]=str.substring(j,k);return }}} and my HTML <script type="text/javascript" src="cart.js" /> </script> <link rel="stylesheet" type="text/css" href="shopping_cart.css" /> <title> A title </title> </head> <body> <form name="form1" method="post" action="data.php" > <div id="product1"> <p id="title1"><b>Star Wars Tie Interceptor</b></p> <img src="images/DS.jpg" /> <p id="price1">Price £39.99</p> <p><b>Qty</b></p> <select name="qty"> <option value="0">0</option> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> </select> <input type="button" value="Add to cart" onclick="cart()" /> </div>

  • trie reg exp parse step over char and continue

    - by forest.peterson
    Setup: 1) a string trie database formed from linked nodes and a vector array linking to the next node terminating in a leaf, 2) a recursive regular expression function that if A) char '*' continues down all paths until string length limit is reached, then continues down remaining string paths if valid, and B) char '?' continues down all paths for 1 char and then continues down remaining string paths if valid. 3) after reg expression the candidate strings are measured for edit distance against the 'try' string. Problem: the reg expression works fine for adding chars or swapping ? for a char but if the remaining string has an error then there is not a valid path to a terminating leaf; making the matching function redundant. I tried adding a 'step-over' ? char if the end of the node vector was reached and then followed every path of that node - allowing this step-over only once; resulted in a memory exception; I cannot find logically why it is accessing the vector out of range - bactracking? Questions: 1) how can the regular expression step over an invalid char and continue with the path? 2) why is swapping the 'sticking' char for '?' resulting in an overflow? Function: void Ontology::matchRegExpHelper(nodeT *w, string inWild, Set<string> &matchSet, string out, int level, int pos, int stepover) { if (inWild=="") { matchSet.add(out); } else { if (w->alpha.size() == pos) { int testLength = out.length() + inWild.length(); if (stepover == 0 && matchSet.size() == 0 && out.length() > 8 && testLength == tokenLength) {//candidate generator inWild[0] = '?'; matchRegExpHelper(w, inWild, matchSet, out, level, 0, stepover+1); } else return; //giveup on this path } if (inWild[0] == '?' || (inWild[0] == '*' && (out.length() + inWild.length() ) == level ) ) { //wild matchRegExpHelper(w->alpha[pos].next, inWild.substr(1), matchSet, out+w->alpha[pos].letter, level, 0, stepover);//follow path -> if ontology is full, treat '*' like a '?' } else if (inWild[0] == '*') matchRegExpHelper(w->alpha[pos].next, '*'+inWild.substr(1), matchSet, out+w->alpha[pos].letter, level, 0, stepover); //keep adding chars if (inWild[0] == w->alpha[pos].letter) //follow self matchRegExpHelper(w->alpha[pos].next, inWild.substr(1), matchSet, out+w->alpha[pos].letter, level, 0, stepover); //follow char matchRegExpHelper(w, inWild, matchSet, out, level, pos+1, stepover);//check next path } } Error Message: +str "Attempt to access index 1 in a vector of size 1." std::basic_string<char,std::char_traits<char>,std::allocator<char> > +err {msg="Attempt to access index 1 in a vector of size 1." } ErrorException Note: this function works fine for hundreds of test strings with '*' wilds if the extra stepover gate is not used Semi-Solved: I place a pos < w->alpha.size() condition on each path that calls w->alpha[pos]... - this prevented the backtrack calls from attempting to access the vector with an out of bounds index value. Still have other issues to work out - it loops infinitely adding the ? and backtracking to remove it, then repeat. But, moving forward now. Revised question: why during backtracking is the position index accumulating and/or not deincrementing - so at somepoint it calls w->alpha[pos]... with an invalid position that is either remaining from the next node or somehow incremented pos+1 when passing upward?

  • Defend PHP; convince me it isn't horrible

    - by Jason L
    I made a tongue-in-cheek comment in another question thread calling PHP a terrible language and it got down-voted like crazy. Apparently there are lots of people here who love PHP. So I'm genuinely curious. What am I missing? What makes PHP a good language? Here are my reasons for disliking it: PHP has inconsistent naming of built-in and library functions. Predictable naming patterns are important in any design. PHP has inconsistent parameter ordering of built-in functions, eg array_map vs. array_filter which is annoying in the simple cases and raises all sorts of unexpected behaviour or worse. The PHP developers constantly deprecate built-in functions and lower-level functionality. A good example is when they deprecated pass-by-reference for functions. This created a nightmare for anyone doing, say, function callbacks. A lack of consideration in redesign. The above deprecation eliminated the ability to, in many cases, provide default keyword values for functions. They fixed this in PHP 5, but they deprecated the pass-by-reference in PHP 4! Poor execution of name spaces (formerly no name spaces at all). Now that name spaces exist, what do we use as the dereference character? Backslash! The character used universally for escaping, even in PHP! Overly-broad implicit type conversion leads to bugs. I have no problem with implicit conversions of, say, float to integer or back again. But PHP (last I checked) will happily attempt to magically convert an array to an integer. Poor recursion performance. Recursion is a fundamentally important tool for writing in any language; it can make complex algorithms far simpler. Poor support is inexcusable. Functions are case insensitive. I have no idea what they were thinking on this one. A programming language is a way to specify behavior to both a computer and a reader of the code without ambiguity. Case insensitivity introduces much ambiguity. PHP encourages (practically requires) a coupling of processing with presentation. Yes, you can write PHP that doesn't do so, but it's actually easier to write code in the incorrect (from a sound design perspective) manner. PHP performance is abysmal without caching. Does anyone sell a commercial caching product for PHP? Oh, look, the designers of PHP do. Worst of all, PHP convinces people that designing web applications is easy. And it does indeed make much of the effort involved much easier. But the fact is, designing a web application that is both secure and efficient is a very difficult task. By convincing so many to take up programming, PHP has taught an entire subgroup of programmers bad habits and bad design. It's given them access to capabilities that they lack the understanding to use safely. This has led to PHP's reputation as being insecure. (However, I will readily admit that PHP is no more or less secure than any other web programming language.) What is it that I'm missing about PHP? I'm seeing an organically-grown, poorly-managed mess of a language that's spawning poor programmers. So convince me otherwise!

  • opengl - Rendering multiple cubes

    - by opiop65
    I have this code (Doesn't work at all) static void initGl() { glViewport(0, 0, Display.getWidth(), Display.getHeight()); glMatrixMode(GL_PROJECTION); glLoadIdentity(); GLU.gluPerspective(45.0f, Display.getWidth() / Display.getHeight(), 1.0f, 1000.0f); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glClearColor(0.0f, 0.0f, 0.0f, 0.0f); glClearDepth(1.0f); glDepthFunc(GL_LEQUAL); glEnable(GL_DEPTH_TEST); glShadeModel(GL_SMOOTH); glHint(GL_PERSPECTIVE_CORRECTION_HINT, GL_NICEST); } public static void renderGL() { glViewport(0, 0, Display.getWidth(), Display.getHeight()); glClearColor(0.0f, 0.0f, 0.0f, 0.5f); glLoadIdentity(); glTranslatef(0.0f, 0.0f, -60.0f); drawCube(); } public static void drawCube() { for (int x = 0; x < 100; x++) { for (int y = 0; y < 100; y++) { for (int z = 0; z < 100; z++) { glBegin(GL_QUADS); glColor3f(1, 0, 0); glVertex3f(-x, -y, z); glVertex3f(x, -y, z); glVertex3f(x, y, z); glVertex3f(-x, y, z); glColor3f(1, 0, 1); glVertex3f(x, -y, -z); glVertex3f(-x, -y, -z); glVertex3f(-x, y, -z); glVertex3f(x, y, -z); glColor3f(1, 1, 1); glVertex3f(-x, y, z); glVertex3f(x, y, z); glVertex3f(x, y, -z); glVertex3f(-x, y, -z); glColor3f(0, 0, 1); glVertex3f(x, -y, z); glVertex3f(-x, -y, z); glVertex3f(-x, -y, -z); glVertex3f(x, -y, -z); glColor3f(1, 1, 0); glVertex3f(x, -y, z); glVertex3f(x, -y, -z); glVertex3f(x, y, -z); glVertex3f(x, y, z); glColor3f(0, 2, 1); glVertex3f(-x, -y, -z); glVertex3f(-x, -y, z); glVertex3f(-x, y, z); glVertex3f(-x, y, -z); glEnd(); } } } All it does it freeze up the program and eventually it will render the red side of the cube. This obviously has to do with gltranslatef, but I don't know why that isn't working. My question is, how do I render multiple cubes at once? Are there any tutorials out there on voxel engines? Sorry for the horrible code, I realize I probably need a array to do this. I'm quite new at opengl.

  • mysql_fetch_array() problem

    - by Marty
    So I have 3 DB tables that are all identical in every way (data is different) except the name of the table. I did this so I could use one piece of code with a switch like so: function disp_bestof($atts) { extract(shortcode_atts(array( 'topic' => '' ), $atts)); $connect = mysql_connect("localhost","foo","bar"); if (!$connect) { die('Could not connect: ' . mysql_error()); } switch ($topic) { case "attorneys": $bestof_query = "SELECT * FROM attorneys p JOIN (awards a, categories c, awardLevels l) ON (a.id = p.id AND c.id = a.category AND l.id = a.level) ORDER BY a.category, a.level ASC"; $category_query = "SELECT * FROM categories"; $db = mysql_select_db('roanoke_BestOf_TopAttorneys'); $query = mysql_query($bestof_query); $categoryQuery = mysql_query($category_query); break; case "physicians": $bestof_query = "SELECT * FROM physicians p JOIN (awards a, categories c, awardLevels l) ON (a.id = p.id AND c.id = a.category AND l.id = a.level) ORDER BY a.category, a.level ASC"; $category_query = "SELECT * FROM categories"; $db = mysql_select_db('roanoke_BestOf_TopDocs'); $query = mysql_query($bestof_query); $categoryQuery = mysql_query($category_query); break; case "dining": $bestof_query = "SELECT * FROM restaurants p JOIN (awards a, categories c, awardLevels l) ON (a.id = p.id AND c.id = a.category AND l.id = a.level) ORDER BY a.category, a.level ASC"; $category_query = "SELECT * FROM categories"; $db = mysql_select_db('roanoke_BestOf_DiningAwards'); $query = mysql_query($bestof_query); $categoryQuery = mysql_query($category_query); break; default: $bestof_query = "switch on $best did not match required case(s)"; break; } $category = ''; while( $result = mysql_fetch_array($query) ) { if( $result['category'] != $category ) { $category = $result['category']; //echo "<div class\"category\">"; $bestof_content .= "<h2>".$category."</h2>\n"; //echo "<ul>"; Now, this whole thing works PERFECT for the first two cases, but the third one "dining" breaks with this error: Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource ... on line 78 Line 78 is the while() at the bottom. I have checked and double checked and can't figure what the problem is. Here's the DB structure for 'restaurants': CREATE TABLE `restaurants` ( `id` int(10) NOT NULL auto_increment, `restaurant` varchar(255) default NULL, `address1` varchar(255) default NULL, `address2` varchar(255) default NULL, `city` varchar(255) default NULL, `state` varchar(255) default NULL, `zip` double default NULL, `phone` double default NULL, `URI` varchar(255) default NULL, `neighborhood` varchar(255) default NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM AUTO_INCREMENT=249 DEFAULT CHARSET=utf8 Does anyone see what I'm doing wrong here? I'm passing "dining" to the function and as I said before, the first two cases in the switch work fine. I'm sure it's something stupid...

  • How to reduce virtual memory by optimising my PHP code?

    - by iCeR
    My current code (see below) uses 147MB of virtual memory! My provider has allocated 100MB by default and the process is killed once run, causing an internal error. The code is utilising curl multi and must be able to loop with more than 150 iterations whilst still minimizing the virtual memory. The code below is only set at 150 iterations and still causes the internal server error. At 90 iterations the issue does not occur.

  • nginx bad gateway 502 with mono fastcgi

    - by Bradley Lederholz Leatherwood
    Hello so I have been trying to get my website to run on mono (on ubuntu server) and I have followed these tutorials almost to the letter: However when my directory is not blank fastcgi logs reveal this: Notice Beginning to receive records on connection. Error Failed to process connection. Reason: Exception has been thrown by the target of an invocation. I am not really sure what this means, and depending on what I do I can get another error that tells me the resource cannot be found: The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Edit: I am now getting a nginx gateway error. My nginx configuration file looks like this: server { listen 2194; server_name localhost; access_log $HOME/WWW/nginx.log; location / { root $HOME/WWW/dev/; index index.html index.html default.aspx Default.aspx Index.cshtml; fastcgi_index Views/Home/; fastcgi_pass 127.0.0.1:8000; include /etc/nginx/fastcgi_params; } } Running the entire thing with xsp4 I have discovered what the "Exception has been thrown by the target of an invocation."

  • Not sure why I'm getting a NullPointerException when creating a Swing component

    - by Alex
    The error occurs when creating the Box object. public void drawBoard(Board board){ for(int row = 0; row < 8; row++){ for(int col = 0; col < 8; col++){ Box box = new Box(board.getSquare(col, row).getColour(), col, row); squarePanel[col][row].add(box); } } Board is given from the Game constructor here (another class): public Game() throws Throwable{ View graphics = new View(); board = new Board(); board.setDefault(); graphics.drawBoard(board); } The Board constructor looks like this: public Board(){ grid = new Square[COLUMNS][ROWS]; for(int row = 0; row < 8; row++){ for(int col = 0; col < 8; col++){ grid[col][row] = new Square(this); } } for(int row = 0; row < 8; row++){ for(int col = 0; col < 4; col++){ int odd = 2*col + 1; int even = 2*col; getSquare(odd, row).setColour(Color.BLACK); getSquare(even, row).setColour(Color.WHITE); } } } And finally the Box class: class Box extends JComponent{ Color boxColour; int col, row; public Box(Color boxColour, int col, int row){ this.boxColour = boxColour; this.col = col; this.row = row; repaint(); } public void paint(Graphics drawBox){ drawBox.setColor(boxColour); drawBox.drawRect(50*col, 50*row, 50, 50); drawBox.fillRect(50*col, 50*row, 50, 50); } } So while looping through the array, it uses the two integers as coordinates to create the Box. The coordinates are referenced and then repaint() is run. The box also gets the colour, using the two integers, from the Square in the Board class. Since the colour is already set, before the drawBoard(board) method is run, that shouldn't be a problem, right? Exception in thread "main" java.lang.NullPointerException at View.drawBoard(View.java:38) at Game.<init>(Game.java:21) at Game.main(Game.java:14) The relevant part of Square import java.awt.Color; public class Square { private Piece piece; private Board board; private Color squareColour; public Square(Board board){ this.board = board; } public void setColour(Color squareColour){ this.squareColour = squareColour; } public Color getColour(){ return squareColour; }

  • Having trouble storing a CRTP based class in a vector

    - by user366834
    Hi, Im not sure if this can be done, im just delving into templates so perhaps my understanding is a bit wrong. I have a Platoon of soldiers, the platoon inherits from a formation to pick up the formations properties, but because i could have as many formations as i can think of I chose to use the CRTP to create the formations, hoping that i could make a vector or array of Platoon to store the platoons in. but, of course, when i make a Platoon, it wont store it in the vector, "types are unrelated" Is there any way around this ? i read about "Veneers" which are similar and that they work with arrays but i cant get it to work, perhaps im missing something. here's some code: (sorry about the formatting, the code is here in my post but its not showing up for some reason ) template < class TBase > class IFormation { public : ~IFormation(){} bool IsFull() { return m_uiMaxMembers == m_uiCurrentMemCount; } protected: unsigned int m_uiCurrentMemCount; unsigned int m_uiMaxMembers; IFormation( unsigned int _uiMaxMembers ): m_uiMaxMembers( _uiMaxMembers ), m_uiCurrentMemCount( 0 ){} // only allow use as a base class. void SetupFormation( std::vector<MySoldier*>& _soldierList ){}; // must be implemented in derived class }; ///////////////////////////////////////////////////////////////////////////////// // PHALANX FORMATION class Phalanx : public IFormation<Phalanx> { public: Phalanx( ): IFormation( 12 ), m_fDistance( 4.0f ) {} ~Phalanx(){} protected: float m_fDistance; // the distance between soldiers void SetupFormation( std::vector<MySoldier*>& _soldierList ); }; /////////////////////////////////////////////////////////////////////////////////// // COLUMN FORMATINO class Column : public IFormation< Column > { public : Column( int _numOfMembers ): IFormation( _numOfMembers ) {} ~Column(); protected: void SetupFormation( std::vector<MySoldier*>& _soldierList ); }; I then use these formations in the platoon class to derive, so that platoon gets the relevant SetupFormation() function: template < class Formation > class Platoon : public Formation { public: **** platoon code here }; everything works great and as expected up until this point. now, as my general can have multiple platoons, I need to store the platoons. typedef Platoon< IFormation<> > TPlatoon; // FAIL typedef std::vector<TPlatoon*> TPlatoons; TPlatoon m_pPlatoons m_pPlatoons.push_back( new Platoon<Phalanx> ); // FAIL, types unrelated. typedef Platoon< IFormation< TPlatoon; fails because i need to specify a template parameter, yet specifying this will only allow me to store platoons created with the same template parameter. so i then created FormationBase class FormationBase { public: virtual bool IsFull() = 0; virtual void SetupFormation( std::vector<MySoldier*>& _soldierList ) = 0; }; and made IFormation publicly inherit from that, and then changed the typedef to typedef Platoon< IFormation< FormationBase > > TPlatoon; but still no love. now in my searches i have not found info that says this is possible - or not possible.

  • Need a hand understanding this Java code please :-)

    - by Brian
    Hi all, Just wondering if anyone would be able to take a look at this code for implementing the quicksort algorithm and answer me a few questions, please :-) public class Run { /*************************************************************************** * Quicksort code from Sedgewick 7.1, 7.2. **************************************************************************/ public static void quicksort(double[] a) { //shuffle(a); // to guard against worst-case quicksort(a, 0, a.length - 1, 0); } static void quicksort(final double[] a, final int left, final int right, final int tdepth) { if (right <= left) return; final int i = partition(a, left, right); if ((tdepth < 4) && ((i - left) > 1000)) { final Thread t = new Thread() { public void run() { quicksort(a, left, i - 1, tdepth + 1); } }; t.start(); quicksort(a, i + 1, right, tdepth + 1); try { t.join(); } catch (InterruptedException e) { throw new RuntimeException("Cancelled", e); } } else { quicksort(a, left, i - 1, tdepth); quicksort(a, i + 1, right, tdepth); } } // partition a[left] to a[right], assumes left < right private static int partition(double[] a, int left, int right) { int i = left - 1; int j = right; while (true) { while (less(a[++i], a[right])) // find item on left to swap ; // a[right] acts as sentinel while (less(a[right], a[--j])) // find item on right to swap if (j == left) break; // don't go out-of-bounds if (i >= j) break; // check if pointers cross exch(a, i, j); // swap two elements into place } exch(a, i, right); // swap with partition element return i; } // is x < y ? private static boolean less(double x, double y) { return (x < y); } // exchange a[i] and a[j] private static void exch(double[] a, int i, int j) { double swap = a[i]; a[i] = a[j]; a[j] = swap; } // shuffle the array a[] private static void shuffle(double[] a) { int N = a.length; for (int i = 0; i < N; i++) { int r = i + (int) (Math.random() * (N - i)); // between i and N-1 exch(a, i, r); } } // test client public static void main(String[] args) { int N = 5000000; // Integer.parseInt(args[0]); // generate N random real numbers between 0 and 1 long start = System.currentTimeMillis(); double[] a = new double[N]; for (int i = 0; i < N; i++) a[i] = Math.random(); long stop = System.currentTimeMillis(); double elapsed = (stop - start) / 1000.0; System.out.println("Generating input: " + elapsed + " seconds"); // sort them start = System.currentTimeMillis(); quicksort(a); stop = System.currentTimeMillis(); elapsed = (stop - start) / 1000.0; System.out.println("Quicksort: " + elapsed + " seconds"); } } My questions are: What is the purpose of the variable tdepth? Is this considered a "proper" implementation of a parallel quicksort? I ask becuase it doesn't use implements Runnable or extends Thread... If it doesn't already, is it possible to modify this code to use multiple threads? By passing in the number of threads you want to use as a parameter, for example...? Many thanks, Brian

  • Javascript and Twitter API rate limitation? (Changing variable values in a loop)

    - by Pablo
    Hello, I have adapted an script from an example of http://github.com/remy/twitterlib. It´s a script that makes one query each 10 seconds to my Twitter timeline, to get only the messages that begin with a musical notation. It´s already working, but I don´t know it is the better way to do this... The Twitter API has a rate limit of 150 IP access per hour (queries from the same user). At this time, my Twitter API is blocked at 25 minutes because the 10 seconds frecuency between posts. If I set up a frecuency of 25 seconds between post, I am below the rate limit per hour, but the first 10 posts are shown so slowly. I think this way I can guarantee to be below the Twitter API rate limit and show the first 10 posts at normal speed: For the first 10 posts, I would like to set a frecuency of 5 seconds between queries. For the rest of the posts, I would like to set a frecuency of 25 seconds between queries. I think if making somewhere in the code a loop with the previous sentences, setting the "frecuency" value from 5000 to 25000 after the 10th query (or after 50 seconds, it´s the same), that´s it... Can you help me on modify this code below to make it work? Thank you in advance. var Queue = function (delay, callback) { var q = [], timer = null, processed = {}, empty = null, ignoreRT = twitterlib.filter.format('-"RT @"'); function process() { var item = null; if (q.length) { callback(q.shift()); } else { this.stop(); setTimeout(empty, 5000); } return this; } return { push: function (item) { var green = [], i; if (!(item instanceof Array)) { item = [item]; } if (timer == null && q.length == 0) { this.start(); } for (i = 0; i < item.length; i++) { if (!processed[item[i].id] && twitterlib.filter.match(item[i], ignoreRT)) { processed[item[i].id] = true; q.push(item[i]); } } q = q.sort(function (a, b) { return a.id > b.id; }); return this; }, start: function () { if (timer == null) { timer = setInterval(process, delay); } return this; }, stop: function () { clearInterval(timer); timer = null; return this; }, empty: function (fn) { empty = fn; return this; }, q: q, next: process }; }; $.extend($.expr[':'], { below: function (a, i, m) { var y = m[3]; return $(a).offset().top y; } }); function renderTweet(data) { var html = ''; html += ''; html += twitterlib.ify.clean(data.text); html += ''; since_id = data.id; return html; } function passToQueue(data) { if (data.length) { twitterQueue.push(data.reverse()); } } var frecuency = 10000; // The lapse between each new Queue var since_id = 1; var run = function () { twitterlib .timeline('twitteruser', { filter : "'?'", limit: 10 }, passToQueue) }; var twitterQueue = new Queue(frecuency, function (item) { var tweet = $(renderTweet(item)); var tweetClone = tweet.clone().hide().css({ visibility: 'hidden' }).prependTo('#tweets').slideDown(1000); tweet.css({ top: -200, position: 'absolute' }).prependTo('#tweets').animate({ top: 0 }, 1000, function () { tweetClone.css({ visibility: 'visible' }); $(this).remove(); }); $('#tweets p:below(' + window.innerHeight + ')').remove(); }).empty(run); run();

  • Faulty to use memcache together with a php web-browser-game in this way?

    - by Crowye
    Background We are currently working on a strategy web-browser game based on php, html and javascript. The plan is to have 10,000+ users playing within the same world. Currently we are using memcached to: store json static data, language files store changeable serialized php class objects (such as armies, inventorys, unit-containers, buildings, etc) In the back we have a mysql server running and holding all the game data aswell. When a object is loaded through our ObjectLoader it loads in this order: checks a static hashmap in the script for the object checks memcache if it has already been loaded into it otherwise loads from database, and saves it into memcache and the static temp hashmap We have built the whole game using a class-object-oriented approach where functionality is always made between objects. Beause of this we think we have managed to get a nice structure, and with the help of memcached we have received good request times from client-server when interacting with the game. I'm aware that memcache is not synchronized, and also is not commonly used for holding a full game in memory. In the beginning after a server's startup the load times when loading objects into memcache for the first time will be high, but after the server's been online for a while and most loads are from memcache, the loads will be well reduced. Currently we are saving changed objects into memcache and database at the same time. Earlier we had an idea to save objects into db only after a certain time or at intervals, but due to risk inconsistency if the memcache/server went down, we skipped it for now. Client requests to server often return object's status simple json-format without changing the object, which in turn is represented in the browser visually with images and javascript. But from time to time depending on when an object was last updated, it updates them with new information (e.g. a build-queue holding planned buildings time-progress is increased, and/or planned-queue-items-array has changed). Questions: Do you see how this could work or are we walking in blindness here? Do you expect us to have a lot of inconsistency issues if someone loads and updates the a memcache objects while someone else does the same? Is it even doable to do it in the way he have done it? Seems to be working fine atm, but so far we have only been 4 people online at the same time.. Is some other cache program more fit for this class-object approach than memcached? Is there any other tips you have for this situation? UPDATE Since it is simply a "normal webpage" (no applet, flash, etc), we are implementing the game so that the server is the only one holding a "real game-state".. the state of the different javascript-objects on the client is more like a approximative version of the server's game state. From time to time and before you do certain things important things, the client's visual state is updated to the server's state (e.g. the client things he can afford a barracks, asks the server to build a barracks, server updates current resources according to income-data on server and then tries to build a barracks or casts an error-message, and then sends the current server-state on resources, buildings back to the client).. It is not a fast-paced game lika real strategy game. More like a quite slow 3-4 months playtime game, where buildings can take +1 minute up to several days to complete.

  • How can I Add newer Data to the start of the xml file (Example inside)

    - by Ofear
    Hi All! After alot of work i finish to make a xml reader and writer... but my problem is that i want the newer data that i insert using my form will be added to the top of the xml file. and not in the bottom.. let me show you an example: this is the XML file: <?xml version="1.0" encoding="utf-8"?> <events> <record> <event>old event</event> <eventDate>1/1/2009</eventDate> <desc>old desc</desc> </record> <record> <event>newer event</event> <eventDate>12/12/2011</eventDate> <desc>newer desc</desc> </record> </events> now.. I want the XML file to be like this: newer data and then old data <?xml version="1.0" encoding="utf-8"?> <events> <record> <event>newer event</event> <eventDate>12/12/2011</eventDate> <desc>newer desc</desc> </record> <record> <event>old event</event> <eventDate>1/1/2009</eventDate> <desc>old desc</desc> </record> </events> This is my add.php (the file that get the POST information from the Form in the main.html : <?php $record = array( 'event' => $_POST['event'], 'eventDate' => $_POST['eventDate'], 'desc' => $_POST['desc'], ); $doc = new DOMDocument(); $doc->load( 'events.xml' ); $doc->formatOutput = true; $r = $doc->getElementsByTagName("events")->item(0); $b = $doc->createElement("record"); $event = $doc->createElement("event"); $event->appendChild( $doc->createTextNode( $record["event"] ) ); $b->appendChild( $event ); $eventDate = $doc->createElement("eventDate"); $eventDate->appendChild( $doc->createTextNode( $record["eventDate"] ) ); $b->appendChild( $eventDate ); $desc = $doc->createElement("desc"); $desc->appendChild( $doc->createTextNode( $record["desc"] ) ); $b->appendChild( $desc ); $r->appendChild( $b ); $doc->save("events.xml"); header("Location: {$_SERVER['HTTP_REFERER']}"); ?> Where do i need to edit to be able to make the *xml as i want?*

    i have a form that auto populates input fields using jquery and ajax i can not get the img url to change in the img src when i select the option from dropdown my dropdown is dynamicaly populated here is is my function <script type="text/javascript"> $(document).ready(function(){ $("#id").change(function(){ $.ajax({ url : 'get_driver_data2.php', type : 'POST', dataType: 'json', data : $('#ContactTrucks').serialize(), success: function( data ) { for(var id in data) { $(id).val( data[id] ); } } }); }); }); </script> here is get_driver_data2.php <?php include ('dbc.php'); $id_selected = $_POST['id']; // Selected Id $query = "SELECT * from admin_dispatch_records where id = '$id_selected' AND driver LIKE '%$username%'"; $result = mysqli_query($dbcon, $query); while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) { $eta = $row['eta']; $time = $row['dispatch_time']; $date = $row['dispatch_date']; $name = $row['name']; $phone = $row['phone']; $vehicleyear = $row['vehicleyear']; $color = $row['color']; $make = $row['make']; $model = $row['model']; $vin = $row['vin']; $plate = $row['plate']; $mileage = $row['mileage']; $pickup = $row['pickup']; $dropoff = $row['dropoff']; $price = $row['price']; $invoice = $row['invoice']; $cash = $row['cash']; $credit = $row['credit']; $check = $row['check']; $po = $row['po']; $billed = $row['billed']; $need_to_bill = $row['need_to_bill']; $getphoto = $row['image_path']; } $arr = array( 'input#eta' => $eta, 'input#dispatch_time' => $time, 'input#dispatch_date' => $date, 'input#name' => $name, 'input#phone' => $phone, 'input#vehicleyear' => $vehicleyear, 'input#color' => $color, 'input#make' => $make, 'input#model' => $model, 'input#vin' => $vin, 'input#plate' => $plate, 'input#mileage' => $mileage, 'textarea#pickup' => $pickup, 'textarea#dropoff' => $dropoff, 'input#price' => $price, 'input#invoice' => $invoice, 'input#cash' => $cash, 'input#credit' => $credit, 'input#check' => $check, 'input#po' => $po, 'input#billed' => $billed, 'input#need_to_bill' => $need_to_bill, 'image#image_path' => $getphoto); echo json_encode( $arr ); ?> a bit of the html <td> <img id="image_path" src="????" /> </td> </tr> </table> <p><strong> <input type="submit" value="Complete Dispatch"> </strong></p> how do i if at all possible populate the src with the database vaule ajax recieved when i change the select box all other data is populated and the string is returned correctlly i have tested that by placing an input box and calling input#image_path = $getphoto. is there syntax for an img tag like the input....textarea....etc. I have tried including the get....php inline and assigning the src to $getphoto no luck there I was looking at trying to make a hidden input field with the ajax passed data and then taking that data and making it a var but can not figure that out either. thanks

  • Showing updated content on the client

    - by tazim
    Hi, I have a file on server which is viewed by the client asynchronously as and when required . The file is going to get modified on server side . Also updates are reflected in browser also In my views.py the code is : def showfiledata(request): somecommand ="ls -l > /home/tazim/webexample/templates/tmp.txt" with open("/home/tazim/webexample/templates/tmp.txt") as f: read_data = f.read() f.closed return_dict = {'filedata':read_data} json = simplejson.dumps(return_dict) return HttpResponse(json,mimetype="application/json") Here, entire file is sent every time client requests for the file data .Instead I want that only modified data sholud be received since sending entire file is not feasible if file size is large . My template code is : < html> < head> < script type="text/javascript" src="/jquerycall/">< /script> < script type="text/javascript"> $(document).ready(function() { var setid = 0; var s = new String(); var my_array = new Array(); function displayfile() { $.ajax({ type:"POST", url:"/showfiledata/", datatype:"json", success:function(data) { s = data.filedata; my_array = s.split("\n"); displaydata(my_array); } }); } function displaydata(my_array) { var i = 0; length = my_array.length; for(i=0;i<my_array.length;i++) { var line = my_array[i] + "\n"; $("#textid").append(line); } } $("#b1").click(function() { setid= setInterval(displayfile,1000); }); $("#b2").click(function() { clearInterval(setid); }) }); < /script> < /head> < body> < form method="post"> < button type="button" id="b1">Click Me< /button>< br>< br> < button type="button" id="b2">Stop< /button>< br>< br> < textarea id="textid" rows="25" cols="70" readonly="true" disabled="true">< /textarea> < /form> </body> </html> Any Help will be beneficial . some sample code will be helpful to understand

  • Help with optimizing C# function via C and/or Assembly

    - by MusiGenesis
    I have this C# method which I'm trying to optimize: // assume arrays are same dimensions private void DoSomething(int[] bigArray1, int[] bigArray2) { int data1; byte A1; byte B1; byte C1; byte D1; int data2; byte A2; byte B2; byte C2; byte D2; for (int i = 0; i < bigArray1.Length; i++) { data1 = bigArray1[i]; data2 = bigArray2[i]; A1 = (byte)(data1 >> 0); B1 = (byte)(data1 >> 8); C1 = (byte)(data1 >> 16); D1 = (byte)(data1 >> 24); A2 = (byte)(data2 >> 0); B2 = (byte)(data2 >> 8); C2 = (byte)(data2 >> 16); D2 = (byte)(data2 >> 24); A1 = A1 > A2 ? A1 : A2; B1 = B1 > B2 ? B1 : B2; C1 = C1 > C2 ? C1 : C2; D1 = D1 > D2 ? D1 : D2; bigArray1[i] = (A1 << 0) | (B1 << 8) | (C1 << 16) | (D1 << 24); } } The function basically compares two int arrays. For each pair of matching elements, the method compares each individual byte value and takes the larger of the two. The element in the first array is then assigned a new int value constructed from the 4 largest byte values (irrespective of source). I think I have optimized this method as much as possible in C# (probably I haven't, of course - suggestions on that score are welcome as well). My question is, is it worth it for me to move this method to an unmanaged C DLL? Would the resulting method execute faster (and how much faster), taking into account the overhead of marshalling my managed int arrays so they can be passed to the method? If doing this would get me, say, a 10% speed improvement, then it would not be worth my time for sure. If it was 2 or 3 times faster, then I would probably have to do it. Note: please, no "premature optimization" comments, thanks in advance. This is simply "optimization".

  • How to manipulate data after its retrieved via remote database

    - by bMon
    So I've used code examples from all over the net and got my app to accurately call a .php file on my server, retrieve the JSON data, then parse the data, and print it. The problem is that its just printing to the screen for sake of the tutorial I was following, but now I need to use that data in other places and need help figuring out that process. The ultimate goal is to return my db query with map coordinates, then plot them on a google map. I have another app in which I manually plot points on a map, so I'll be integrating this app with that once I can get my head around how to correctly manipulate the data returned. public class Remote extends Activity { /** Called when the activity is first created. */ TextView txt; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // Create a crude view - this should really be set via the layout resources // but since its an example saves declaring them in the XML. LinearLayout rootLayout = new LinearLayout(getApplicationContext()); txt = new TextView(getApplicationContext()); rootLayout.addView(txt); setContentView(rootLayout); // Set the text and call the connect function. txt.setText("Connecting..."); //call the method to run the data retreival txt.setText(getServerData(KEY_121)); } public static final String KEY_121 = "http://example.com/mydbcall.php"; private String getServerData(String returnString) { InputStream is = null; String result = ""; //the year data to send //ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(); //nameValuePairs.add(new BasicNameValuePair("year","1970")); try{ HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost(KEY_121); HttpResponse response = httpclient.execute(httppost); HttpEntity entity = response.getEntity(); is = entity.getContent(); }catch(Exception e){ Log.e("log_tag", "Error in http connection "+e.toString()); } //convert response to string try{ BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8); StringBuilder sb = new StringBuilder(); String line = null; while ((line = reader.readLine()) != null) { sb.append(line + "\n"); } is.close(); result=sb.toString(); }catch(Exception e){ Log.e("log_tag", "Error converting result "+e.toString()); } //parse json data try{ JSONArray jArray = new JSONArray(result); for(int i=0;i<jArray.length();i++){ JSONObject json_data = jArray.getJSONObject(i); Log.i("log_tag","longitude: "+json_data.getDouble("longitude")+ ", latitude: "+json_data.getDouble("latitude") ); //Get an output to the screen returnString += "\n\t" + jArray.getJSONObject(i); } }catch(JSONException e){ Log.e("log_tag", "Error parsing data "+e.toString()); } return returnString; } } So the code: returnString += "\n\t" + jArray.getJSONObject(i); is what is currently printing to the screen. What I have to figure out is how to get the data into something I can reference in other spots in the program, and access the individual elements ie: double longitude = jArray.getJSONObject(3).longitude; or something to that effect.. I figure the class getServerData will have to return a Array type or something? Any help is appreciated, thanks.

  • WordPress issues with htaccess causing 500 server error

    - by Scott B
    I have a few customers of my custom wordpress theme that are reporting that their sites have went down over the past few weeks due to a 500 internal server error. In each case, it appears that the htaccess file has been to blame. In one case, the user's hosting company found a "_pvt/service.pwd" line in there that was apparently causing the problem. In another instance, the hosting company indicated that a chron job appeared to be causing the issue and sent the user the following as evidence... root@cherry [/home/login/public_html]# stat .htaccess File: `.htaccess.orig' Size: 587 Blocks: 8 IO Block: 4096 regular file Device: 811h/2065d Inode: 590021607 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 2234/login) Gid: ( 2231/login) Access: 2010-03-07 16:42:01.000000000 -0600 Modify: 2010-03-26 09:15:15.000000000 -0500 Change: 2010-03-26 09:45:05.000000000 -0500 In yet another instance, the user reported this as the cause... The permissions on my .index file somehow got changed to 777 instead of 644 I'm just seeking to help these users understand what's going on, the likely cause and how to prevent it. I also want to eliminate my theme as a potential contributing factor. I have two areas in which I want to submit here to make sure that they are not likely to cause such an issue. They are my permalink rewrite code as well as my upgrade script (which sets 755 on the destination folder (my theme folder). Here's the permalink rewrite code... if (file_exists(ABSPATH.'/wp-admin/includes/taxonomy.php')) { require_once(ABSPATH.'/wp-admin/includes/taxonomy.php'); if(get_option('permalink_structure') !== "/%postname%/" || get_option('mycustomtheme_permalinks') !=="/%postname%/") { $mycustomtheme_permalinks = get_option('mycustomtheme_permalinks'); require_once(ABSPATH . '/wp-admin/includes/misc.php'); require_once(ABSPATH . '/wp-admin/includes/file.php'); global $wp_rewrite; $wp_rewrite->set_permalink_structure($mycustomtheme_permalinks); $wp_rewrite->flush_rules(); } if(!get_cat_ID('topMenu')){wp_create_category('topMenu');} if(!get_cat_ID('hidden')){wp_create_category('hidden');} if(!get_cat_ID('noads')){wp_create_category('noads');} } if (!is_dir(ABSPATH.'wp-content/uploads')) { mkdir(ABSPATH.'wp-content/uploads'); } And here is the relevant lines from my uploader script... // permission settings for newly created folders $chmod = 0755; // Ensures that the correct file was chosen $accepted_types = array('application/zip', 'application/x-zip-compressed', 'multipart/x-zip', 'application/s-compressed'); foreach($accepted_types as $mime_type) { if($mime_type == $type) { $okay = true; break; } } //Safari and Chrome don't register zip mime types. Something better could be used here. $okay = strtolower($name[1]) == 'zip' ? true: false; if(!$okay) { die("This upgrader requires a zip file.

  • Inheriting XML files and modifying values

    - by Veehmot
    This is a question about concept. I have an XML file, let's call it base: <base id="default"> <tags> <tag>tag_one</tag> <tag>tag_two</tag> <tag>tag_three</tag> </tags> <data> <data_a>blue</data_a> <data_b>3</data_b> </data> </base> What I want to do is to be able to extend this XML in another file, modifying individual properties. For example, I want to inherit that file and make a new one with a different data/data_a node: <base id="green" import="default"> <data> <data_a>green</data_a> </data> </base> So far it's pretty simple, it replaces the old data/data_a with the new one. I even can add a new node: <base id="ext" import="default"> <moredata> <data>extended version</data> </moredata> </base> And still it's pretty simple. The problem comes when I want to delete a node or deal with XML Lists (like the tags node). How should I reference a particular index on a list? I was thinking doing something like: <base id="diffList" import="default"> <tags> <tag index="1">this is not anymore tag_two</tag> </tags> </base> And for deleting a node / array index: <base id="deleting" import="default"> <tags> <tag index="2"/> </tags> <data/> </base> <!-- This will result in an XML containing these values: --> <base> <tag>tag_one</tag> <tag>tag_two</tag> </base> But I'm not happy with my solutions. I don't know anything about XSLT or other XML transformation tools, but I think someone must have done this before. The key goal I'm looking for is ease to write the XML by hand (both the base and the "extended"). I'm open to new solutions besides XML, if they are easy to write manually. Thanks for reading.

  • java ioexception error=24 too many files open

    - by MattS
    I'm writing a genetic algorithm that needs to read/write lots of files. The fitness test for the GA is invoking a program called gradif, which takes a file as input and produces a file as output. Everything is working except when I make the population size and/or the total number of generations of the genetic algorithm too large. Then, after so many generations, I start getting this: java.io.FileNotFoundException: testfiles/GradifOut29 (Too many open files). (I get it repeatedly for many different files, the index 29 was just the one that came up first last time I ran it). It's strange because I'm not getting the error after the first or second generation, but after a significant amount of generations, which would suggest that each generation opens up more files that it doesn't close. But as far as I can tell I'm closing all of the files. The way the code is set up is the main() function is in the Population class, and the Population class contains an array of Individuals. Here's my code: Initial creation of input files (they're random access so that I could reuse the same file across multiple generations) files = new RandomAccessFile[popSize]; for(int i=0; i<popSize; i++){ files[i] = new RandomAccessFile("testfiles/GradifIn"+i, "rw"); } At the end of the entire program: for(int i=0; i<individuals.length; i++){ files[i].close(); } Inside the Individual's fitness test: FileInputStream fin = new FileInputStream("testfiles/GradifIn"+index); FileOutputStream fout = new FileOutputStream("testfiles/GradifOut"+index); Process process = Runtime.getRuntime().exec ("./gradif"); OutputStream stdin = process.getOutputStream(); InputStream stdout = process.getInputStream(); Then, later.... try{ fin.close(); fout.close(); stdin.close(); stdout.close(); process.getErrorStream().close(); }catch (IOException ioe){ ioe.printStackTrace(); } Then, afterwards, I append an 'END' to the files to make parsing them easier. FileWriter writer = new FileWriter("testfiles/GradifOut"+index, true); writer.write("END"); try{ writer.close(); }catch(IOException ioe){ ioe.printStackTrace(); } My redirection of stdin and stdout for gradif are from this answer. I tried using the try{close()}catch{} syntax to see if there was a problem with closing any of the files (there wasn't), and I got that from this answer. It should also be noted that the Individuals' fitness tests run concurrently. UPDATE: I've actually been able to narrow it down to the exec() call. In my most recent run, I first ran in to trouble at generation 733 (with a population size of 100). Why are the earlier generations fine? I don't understand why, if there's no leaking, the algorithm should be able to pass earlier generations but fail on later generations. And if there is leaking, then where is it coming from? UPDATE2: In trying to figure out what's going on here, I would like to be able to see (preferably in real-time) how many files the JVM has open at any given point. Is there an easy way to do that?

  • Strange behaviour when simply adding strings in Lazarus - FreePascal

    - by linkcharger
    The program has several "encryption" algorithms. This one should blockwise reverse the input. "He|ll|o " becomes "o |ll|He" (block length of 2). I add two strings, in this case appending the result string to the current "block" string and making that the result. When I add the result first and then the block it works fine and gives me back the original string. But when i try to reverse the order it just gives me the the last "block". Several other functions that are used for "rotation" are above. //amount of blocks function amBl(i1:integer;i2:integer):integer; begin if (i1 mod i2) <> 0 then result := (i1 div i2) else result := (i1 div i2) - 1; end; //calculation of block length function calcBl(keyStr:string):integer; var i:integer; begin result := 0; for i := 1 to Length(keyStr) do begin result := (result + ord(keyStr[i])) mod 5; result := result + 2; end; end; //desperate try to add strings function append(s1,s2:string):string; begin insert(s2,s1,Length(s1)+1); result := s1; end; function rotation(inStr,keyStr:string):string; var //array of chars -> string block,temp:string; //position in block variable posB:integer; //block length and block count variable bl, bc:integer; //null character as placeholder n : ansiChar; begin //calculating block length 2..6 bl := calcBl(keyStr); setLength(block,bl); result := ''; temp := ''; {n := #00;} for bc := 0 to amBl(Length(inStr),bl) do begin //filling block with chars starting from back of virtual block (in inStr) for posB := 1 to bl do begin block[posB] := inStr[bc * bl + posB]; {if inStr[bc * bl + posB] = ' ' then block[posB] := n;} end; //adding the block in front of the existing result string temp := result; result := block + temp; //result := append(block,temp); //result := concat(block,temp); end; end; (full code http://pastebin.com/6Uarerhk) After all the loops "result" has the right value, but in the last step (between "result := block + temp" and the "end;" of the function) "block" replaces the content of "result" with itself completely, it doesn't add result at the end anymore. And as you can see I even used a temp variable to try to work around that.. doesnt change anything though.
