FastCGI Error Access to the script denied

- by ArtWorkAD

I have a Debian Squeeze server running nginx + php-fpm + fastcgi. I have a typo3 installation on this server which runs well. No I installed OTRS and I get an error that I do not understand: 2012/06/25 15:35:38 [error] 16510#0: *34 FastCGI sent in stderr: "Access to the script '/opt/otrs/bin/fcgi-bin/index.pl' has been denied (see security.limit_extensions)" while reading response header from upstream, client: ..., server: support.....com, request: "GET /otrs/index.pl HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "support.....com", referrer: "http://support.....com/" Why do I get this error? The otrs directory is writable for the webserver, so this is not the problem. Any ideas?

Retrieve JSON with stackoverflow API

- by ArtWorkAD

Hi, I want to retrieve the information of my stackoverflow profile as JSON using the api. So I use this link http:/api.stackoverflow.com/1.0/users/401025/. But when I make the request I get a file containing the JSON data. How do I deal with that file using javascript? Here is my code (http://jsfiddle.net/hJhfU/2/): <html> <head> <script> var req; getReputation(); function getReputation(){ req = new XMLHttpRequest(); req.open('GET', 'http://api.stackoverflow.com/1.0/users/401025/'); req.onreadystatechange = processUser; req.send(); } function processUser(){ var res = JSON.parse(req.responseText); alert('test'); } </script> </head> The alert is never fired and req.responseText seems to be empty. Any ideas?

Invert linear linked list

- by ArtWorkAD

Hi, a linear linked list is a set of nodes. This is how a node is defined (to keep it easy we do not distinguish between node an list): class Node{ Object data; Node link; public Node(Object pData, Node pLink){ this.data = pData; this.link = pLink; } public String toString(){ if(this.link != null){ return this.data.toString() + this.link.toString(); }else{ return this.data.toString() ; } } public void inc(){ this.data = new Integer((Integer)this.data + 1); } public void lappend(Node list){ Node child = this.link; while(child != null){ child = child.link; } child.link = list; } public Node copy(){ if(this.link != null){ return new Node(new Integer((Integer)this.data), this.link.copy()); }else{ return new Node(new Integer((Integer)this.data), null); } } public Node invert(){ Node child = this.link; while(child != null){ child = child.link; } child.link = this;.... } } I am able to make a deep copy of the list. Now I want to invert the list so that the first node is the last and the last the first. The inverted list has to be a deep copy. I started developing the invert function but I am not sure. Any Ideas? Update: Maybe there is a recursive way since the linear linked list is a recursive data structure. I would take the first element, iterate through the list until I get to a node that has no child and append the first element, I would repeat this for the second, third....

Coloring text with css using jQuery

- by ArtWorkAD

Hi, I have a little problem adding a class to a span element and so coloring it in order to perform simple validation. Here is my js: function validateKey(){ var length = $('#appkey').val().length; if(length != 8){ $('#appkey').addClass('error'); $('#appKeyInfo').addClass('error'); return false; }else{ $('#appkey').removeClass('error'); $('#appKeyInfo').removeClass('error'); return true; } } And html: <label>KEY</label></br> <input type="text" id="appkey" value=""/></br> <span id="appKeyInfo">Dein App-Key aus 8 Ziffern</span> And the jsfiddle: example Any ideas? UPDATE: coloring of appKeyInfo fails, coloring appkey works. When I remove color:red and type font-weight:bold instead the text is bold on error. when I remove color definition of appKeyInfo the text can be colored red on error, strange thing, but I need a font color for the appKeyInfo

Tower of Hanoi, stop sliding

- by ArtWorkAD

Hi, I developed a solution for the Tower of Hanoi problem: public static void bewege(int h, char quelle, char ablage, char ziel) { if(h > 0){ bewege(h - 1, quelle, ziel, ablage); System.out.println("Move "+ h +" from " + quelle + " to " + ziel); bewege(h - 1, ablage, quelle, ziel); } } It works fine. Now i want to limit the number of slides and throw an exception if a certain limit is reached. I tried it with a counter but it does not work: class HanoiNK{ public static void main(String args[]){ Integer n = Integer.parseInt(args[0]); Integer k = Integer.parseInt(args[1]); try{ bewege(k, n, 'A', 'B', 'C'); }catch(Exception e){ System.out.println(e); } } public static void bewege(int c, int h, char quelle, char ablage, char ziel) throws Exception{ if(h > 0){ if(counter != 0){ bewege(c, h - 1, quelle, ziel, ablage); c--; System.out.println("Move "+ h +" from " + quelle + " to " + ziel); bewege(c, h - 1, ablage, quelle, ziel); c--; }else{ throw new Exception("stop sliding"); } } } } The exception is never thrown. Any ideas?

User interface for messaging app for WP7

- by ArtWorkAD

I have a Message.xaml file that should display a recipient field and a message field like this: The user can add multiple recipients, so the TextBox should be flexible in height. I managed this with following code: <TextBox FontSize="24" Margin="0,0,80,532" Name="absenderField" AcceptsReturn="True" TextWrapping="Wrap" Height="auto" MinHeight="30" MaxWidth="375"> </TextBox> Now the recipient field is growing in height when text is added that does not fit into it. The other TextBox is for the message. The markup is the same as for the recipient field, just the height is different. The first problem is, that when the recipient field growes it goes over the message field but the message field should be aligned at the bottom of the recipient field and move down. how can I achieve that? Now the other problem. When I enter a lot of text to make the message field grow, the recipient field will grow too. This is very strange. Why does this happen? Is it possible to make the text scroll inside the text box? Whole xaml: http://pastebin.com/xPg7rV9e

Understanding linear linked list

- by ArtWorkAD

Hi, I have some problems understanding the linear linked list data structure. This is how I define a list element: class Node{ Object data; Node link; public Node(Object pData, Node pLink){ this.data = pData; this.link = pLink; } } To keep it simple we say that a list are linked nodes so we do not need to define a class list (recursion principle). My problem is that I am really confused in understanding how nodes are connected, more precisely the sequence of the nodes when we connect them. Node n1 = new Node(new Integer(2), null); Node n2 = new Node(new Integer(1), n1); What is link? Is it the previous or the next element? Any other suggestions to help me understanding this data structure?

Execute js on DOMContentLoaded in ff-extension

- by ArtWorkAD

Hi, I want to enable jQuery for my extension. So I want to do something similar to $(document).ready(function() { // put all your jQuery goodness in here. }); So I came up with var app = window.document.getElementById('page'); app.addEventListener("DOMContentLoaded", onPageLoad, false); function onPageLoad(){ alert("test"); } But this does not work at all. Any ideas how to call onPageLoad each time DOM content is reloaded?
