  • Enabling DNS for IPv6 infrastructure

    After successful automatic distribution of IPv6 address information via DHCPv6 in your local network it might be time to start offering some more services. Usually, we would use host names in order to communicate with other machines instead of their bare IPv6 addresses. During the following paragraphs we are going to enable our own DNS name server with IPv6 address resolving. This is the third article in a series on IPv6 configuration: Configure IPv6 on your Linux system DHCPv6: Provide IPv6 information in your local network Enabling DNS for IPv6 infrastructure Accessing your web server via IPv6 Piece of advice: This is based on my findings on the internet while reading other people's helpful articles and going through a couple of man-pages on my local system. What's your name and your IPv6 address? $ sudo service bind9 status * bind9 is running If the service is not recognised, you have to install it first on your system. This is done very easy and quickly like so: $ sudo apt-get install bind9 Once again, there is no specialised package for IPv6. Just the regular application is good to go. But of course, it is necessary to enable IPv6 binding in the options. Let's fire up a text editor and modify the configuration file. $ sudo nano /etc/bind/named.conf.optionsacl iosnet {        127.0.0.1;        192.168.1.0/24;        ::1/128;        2001:db8:bad:a55::/64;};listen-on { iosnet; };listen-on-v6 { any; };allow-query { iosnet; };allow-transfer { iosnet; }; Most important directive is the listen-on-v6. This will enable your named to bind to your IPv6 addresses specified on your system. Easiest is to specify any as value, and named will bind to all available IPv6 addresses during start. More details and explanations are found in the man-pages of named.conf. Save the file and restart the named service. As usual, check your log files and correct your configuration in case of any logged error messages. Using the netstat command you can validate whether the service is running and to which IP and IPv6 addresses it is bound to, like so: $ sudo service bind9 restart $ sudo netstat -lnptu | grep "named\W*$"tcp        0      0 192.168.1.2:53        0.0.0.0:*               LISTEN      1734/named      tcp        0      0 127.0.0.1:53          0.0.0.0:*               LISTEN      1734/named      tcp6       0      0 :::53                 :::*                    LISTEN      1734/named      udp        0      0 192.168.1.2:53        0.0.0.0:*                           1734/named      udp        0      0 127.0.0.1:53          0.0.0.0:*                           1734/named      udp6       0      0 :::53                 :::*                                1734/named   Sweet! Okay, now it's about time to resolve host names and their assigned IPv6 addresses using our own DNS name server. $ host -t aaaa www.6bone.net 2001:db8:bad:a55::2Using domain server:Name: 2001:db8:bad:a55::2Address: 2001:db8:bad:a55::2#53Aliases: www.6bone.net is an alias for 6bone.net.6bone.net has IPv6 address 2001:5c0:1000:10::2 Alright, our newly configured BIND named is fully operational. Eventually, you might be more familiar with the dig command. Here is the same kind of IPv6 host name resolve but it will provide more details about that particular host as well as the domain in general. $ dig @2001:db8:bad:a55::2 www.6bone.net. AAAA More details on the Berkeley Internet Name Domain (bind) daemon and IPv6 are available in Chapter 22.1 of Peter Bieringer's HOWTO on IPv6. Setting up your own DNS zone Now, that we have an operational named in place, it's about time to implement and configure our own host names and IPv6 address resolving. The general approach is to create your own zone database below the bind folder and to add AAAA records for your hosts. In order to achieve this, we have to define the zone first in the configuration file named.conf.local. $ sudo nano /etc/bind/named.conf.local //// Do any local configuration here//zone "ios.mu" {        type master;        file "/etc/bind/zones/db.ios.mu";}; Here we specify the location of our zone database file. Next, we are going to create it and add our host names, our IP and our IPv6 addresses. $ sudo nano /etc/bind/zones/db.ios.mu $ORIGIN .$TTL 259200     ; 3 daysios.mu                  IN SOA  ios.mu. hostmaster.ios.mu. (                                2014031101 ; serial                                28800      ; refresh (8 hours)                                7200       ; retry (2 hours)                                604800     ; expire (1 week)                                86400      ; minimum (1 day)                                )                        NS      server.ios.mu.$ORIGIN ios.mu.server                  A       192.168.1.2server                  AAAA    2001:db8:bad:a55::2client1                 A       192.168.1.3client1                 AAAA    2001:db8:bad:a55::3client2                 A       192.168.1.4client2                 AAAA    2001:db8:bad:a55::4 With a couple of machines in place, it's time to reload that new configuration. Note: Each time you are going to change your zone databases you have to modify the serial information, too. Named loads the plain text zone definitions and converts them into an internal, indexed binary format to improve lookup performance. If you forget to change your serial then named will not use the new records from the text file but the indexed ones. Or you have to flush the index and force a reload of the zone. This can be done easily by either restarting the named: $ sudo service bind9 restart or by reloading the configuration file using the name server control utility - rndc: $ sudo rndc reconfig Check your log files for any error messages and whether the new zone database has been accepted. Next, we are going to resolve a host name trying to get its IPv6 address like so: $ host -t aaaa server.ios.mu. 2001:db8:bad:a55::2Using domain server:Name: 2001:db8:bad:a55::2Address: 2001:db8:bad:a55::2#53Aliases: server.ios.mu has IPv6 address 2001:db8:bad:a55::2 Looks good. Alternatively, you could have just ping'd the system as well using the ping6 command instead of the regular ping: $ ping6 serverPING server(2001:db8:bad:a55::2) 56 data bytes64 bytes from 2001:db8:bad:a55::2: icmp_seq=1 ttl=64 time=0.615 ms64 bytes from 2001:db8:bad:a55::2: icmp_seq=2 ttl=64 time=0.407 ms^C--- ios1 ping statistics ---2 packets transmitted, 2 received, 0% packet loss, time 1001msrtt min/avg/max/mdev = 0.407/0.511/0.615/0.104 ms That also looks promising to me. How about your configuration? Next, it might be interesting to extend the range of available services on the network. One essential service would be to have web sites at hand.

  • Extjs Tooltips, IFrames and IE => Problems

    - by Chau
    I have an application using OpenLayers, Extjs and GeoExt. My application runs fine, but I need it to be placed inside an IFrame in another page. When doing this, my toolbar becomes responseless in Internet Explorer. The cause is Ext.QuickTips.init();. Comment out this line and everything works fine - except the quick tips ofcourse =) But why is it causing problems? Is it because I'm using it wrong, placing it wrong or just because it doesn't like IE and IFrames?

  • What is the best way to slide a panel in WPF?

    - by Kris Erickson
    I have a fairly simple UserControl that I have made (pardon my Xaml I am just learning WPF) and I want to slide the off the screen. To do so I am animating a translate transform (I also tried making the Panel the child of a canvas and animating the X position with the same results), but the panel moves very jerkily, even on a fairly fast new computer. What is the best way to slide in and out (preferably with KeySplines so that it moves with inertia) without getting the jerkyness. I only have 8 buttons on the panel, so I didn't think it would be too much of a problem. Here is the Xaml I am using, it runs fine in Kaxaml, but it is very jerky and slow (as well as being jerkly and slow when run compiled in a WPF app). <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="1002" Height="578"> <UserControl.Resources> <Style TargetType="Button"> <Setter Property="Control.Padding" Value="4"/> <Setter Property="Control.Margin" Value="10"/> <Setter Property="Control.Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Grid Name="backgroundGrid" Width="210" Height="210" Background="#00FFFFFF"> <Grid.BitmapEffect> <BitmapEffectGroup> <DropShadowBitmapEffect x:Name="buttonDropShadow" ShadowDepth="2"/> <OuterGlowBitmapEffect x:Name="buttonGlow" GlowColor="#A0FEDF00" GlowSize="0"/> </BitmapEffectGroup> </Grid.BitmapEffect> <Border x:Name="background" Margin="1,1,1,1" CornerRadius="15"> <Border.Background> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <LinearGradientBrush.GradientStops> <GradientStop Offset="0" Color="#FF0062B6"/> <GradientStop Offset="1" Color="#FF0089FE"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> </Border.Background> </Border> <Border Margin="1,1,1,0" BorderBrush="#FF000000" BorderThickness="1.5" CornerRadius="15"/> <ContentPresenter HorizontalAlignment="Center" Margin="{TemplateBinding Control.Padding}" VerticalAlignment="Center" Content="{TemplateBinding ContentControl.Content}" ContentTemplate="{TemplateBinding ContentControl.ContentTemplate}"/> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> </UserControl.Resources> <Canvas> <Grid x:Name="Panel1" Height="578" Canvas.Left="0" Canvas.Top="0"> <Grid.RenderTransform> <TransformGroup> <TranslateTransform x:Name="panelTranslate" X="0" Y="0"/> </TransformGroup> </Grid.RenderTransform> <Grid.RowDefinitions> <RowDefinition Height="287"/> <RowDefinition Height="287"/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition x:Name="Panel1Col1"/> <ColumnDefinition x:Name="Panel1Col2"/> <ColumnDefinition x:Name="Panel1Col3"/> <ColumnDefinition x:Name="Panel1Col4"/> <!-- Set width to 0 to hide a column--> </Grid.ColumnDefinitions> <Button x:Name="Panel1Product1" Grid.Column="0" Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Center"> <Button.Triggers> <EventTrigger RoutedEvent="Button.Click" SourceName="Panel1Product1"> <EventTrigger.Actions> <BeginStoryboard> <Storyboard> <DoubleAnimation BeginTime="00:00:00.6" Duration="0:0:3" From="0" Storyboard.TargetName="panelTranslate" Storyboard.TargetProperty="X" To="-1000"/> </Storyboard> </BeginStoryboard> </EventTrigger.Actions> </EventTrigger> </Button.Triggers> </Button> <Button x:Name="Panel1Product2" Grid.Column="0" Grid.Row="1" HorizontalAlignment="Center" VerticalAlignment="Center"/> <Button x:Name="Panel1Product3" Grid.Column="1" Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Center"/> <Button x:Name="Panel1Product4" Grid.Column="1" Grid.Row="1" HorizontalAlignment="Center" VerticalAlignment="Center"/> <Button x:Name="Panel1Product5" Grid.Column="2" Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Center"/> <Button x:Name="Panel1Product6" Grid.Column="2" Grid.Row="1" HorizontalAlignment="Center" VerticalAlignment="Center"/> <Button x:Name="Panel1Product7" Grid.Column="3" Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Center"/> <Button x:Name="Panel1Product8" Grid.Column="3" Grid.Row="1" HorizontalAlignment="Center" VerticalAlignment="Center"/> </Grid> </Canvas> </UserControl>

  • Scrum Master Stephen Forte Teaches Agile Development, Silverlight and BI at GIDS 2010

    - by rajesh ahuja
    Great Indian Developer Summit 2010 – Gold Standard for India's Software Developer Ecosystem Bangalore, March 25, 2010: The author of several books on application and database development including Programming SQL Server 2008 and certified Scrum Master Stephen Forte is coming this summer to India's biggest summit for the developer ecosystem - Great Indian Developer Summit. At the summit, Stephen will conduct a workshop guaranteed to give attendees a jump start in taking a certified scrum master exam. Scrum, one of the most popular Agile project management and development methods, which is starting to be adopted at major corporations and on very large projects. After an introduction to the basics of Scrum like project planning and estimation, the Scrum Master, team, product owner and burn down, and of course the daily Scrum, Stephen will show many real world applications of the methodology drawn from his own experience as a Scrum Master. Negotiating with the business, estimation and team dynamics are all discussed as well as how to use Scrum in small organizations, large enterprise environments and consulting environments. Stephen will also discuss using Scrum with virtual teams and an off-shoring environment. He will then take a look at the tools we will use for Agile development, including planning poker, unit testing, and much more. On 20th April at the GIDS.NET Conference, Stephen will also conduct a series of sessions on Microsoft computing technologies. He will teach how to build data driven, n-tier Rich Internet Applications (RIA) with Silverlight 4.0. Line of business applications (LOB) in Silverlight 4.0 are easy by tapping the power of WCF RIA Services, the Silverlight Toolkit, and elevated out of browser support. Stephen's demo centric session will walk you through an example of building a LOB application with Silverlight 4.0. See how Silverlight and WCF RIA Services support domain logic, services, data binding, validation, server based paging, authentication, authorization and much more. Silverlight 4.0 means business. Silverlight runs C# and Visual Basic code, and so it seems natural that a business application might share some code between the Silverlight client and its ASP.NET Web server. You may want to run some code client-side for interactivity, but re-run that code on the server for security or reliability. This is possible, and there are several techniques you can use to accomplish this goal. In Stephen's second talk learn about the various techniques and their pros and cons. Some techniques work better in C#, others in VB. Still others are simpler with a little extra tooling or code-generation. Any serious Silverlight business application will almost certainly face this issue, and this session gets you going fast. In the third talk, Stephen will explain how to properly architect and deploy a BI application using a mix of some exciting new tools and some old familiar ones. He will start with a traditional relational transaction centric database (OLTP) and explore ways to build a data warehouse (OLAP), looking at the star and snowflake schemas. Next he will look at the process of extraction, transformation, and loading (ETL) your OLTP data into your data warehouse. Different techniques for ETL will be described and the various tradeoffs will be discussed. Then he will look at using the warehouse for reporting, drill down, and data analysis in Microsoft Excel's PowerPivot 2010. The session will round off by showing how to properly build a cube and build a data analysis application on top of that cube, and conclude by looking at some tools to help with the data visualization process. Every year, GIDS is a game changer for several thousands of IT professionals, providing them with a competitive edge over their peers, enlightening them with bleeding-edge information most useful in their daily jobs, helping them network with world-class experts and visionaries, and providing them with a much needed thrust in their careers.

    Great Indian Developer Summit 2010 – India's Biggest Polyglot Conference and Workshops for IT Software Professionals Bangalore, April 9, 2010: The GIDS.Web Conference and Workshops has announced the complete program of over 30 sessions on how browser and rich web technologies such as AJAX, DHTML, Mashups, Web 2.0, Enterprise 2.0 technologies, and Rich UI technologies are making money and gaining market-share for some of the leading businesses in the world. The GIDS.Web track at Great Indian Developer Summit takes place 21 and 23 April 2010, at the Indian Institute of Science in Bangalore. As one of the longest running independent developer conferences in India, GIDS.Web at the Great Indian Developer Summit 2010 is uniquely positioned to provide a blend of practical, pragmatic and immediately applicable knowledge and a glimpse of the future of technology. During 21 and 23 April 2010, GIDS.Web offers a multi-track conference, workshops, expo show floor, and networking opportunities. The first keynote at GIDS.Web is led by the leading Java EE and Ajax developer, speaker, and author Marty Hall. The best of India's Java and RIA programmers have learnt the subject from Marty's seminal books Core Servlets and JavaServer Pages (first and second editions), More Servlets and JavaServer Pages, and Core Web Programming (first and second editions) from Prentice Hall and Sun Microsystems Press. Marty's keynote address is a comparison of approaches to building rich Internet applications with Ajax. Marty says Ajax development is difficult, and there are several fundamentally different strategies to building Ajaxified Web applications. The keynote address will survey the three most important of these approaches: using an Ajax-enabled JavaScript library such as jQuery, Prototype, Scriptaculous, Dojo, or Ext/JS; using a Web framework such as JSF 2.0 or Struts 2 that has integrated Ajax support; using the Google Web Toolkit (GWT) to build "pure Java" Ajax applications. The talk will compare and contrast these three approaches, discussing the types of applications that fit best for each option. Over the course of the summit Marty will conduct several more sessions on "Choosing an Ajax/JavaScript Toolkit: A Comparison of the Most Popular JavaScript Libraries", "Pure Java Ajax: An Overview of GWT 2.0", "Integrated Ajax Support in JSF 2.0" and "Ajax Support in the Prototype JavaScript Library". The second keynote by the head of Adobe's Flash initiative in India, Ramesh Srinivasaraghavan, explores the state of art in web application development and identify trends that could transform the way we create and use web applications. The talk explains how the Adobe Flash Platform has fuelled this revolution with an integrated set of technologies for delivering the most compelling applications, content and video to the widest possible audience.

  • Cannot connect to one of my WCF services, not even with telnet

    - by Ecyrb
    I have six wcf services that I'm hosting in a windows service. Everything works great on my machine (Windows 7) but when I try it in production (Windows Server 2003) I cannot connect to one of my six services, ReportsService. I figured I must have a typo, but everything looks right. I've even rewritten that section of the config file just to be sure. I've turned on WCF tracing, but it never shows the call to my service; nothing helpful in there. I tried connecting to the port (9005) with telnet, but it failed. I can connect to all other services (ports 9001-4 and 9006) just fine. I thought that maybe there was a problem with port 9005, so I changed it to 9007 and still couldn't connect. I had one of my working services host on 9005 and it actually worked fine. So I'm pretty sure there's nothing wrong with the port or any firewall settings. Whatever port I tell ReportsService to use fails. Now I'm out of ideas. It seems like it's not hosting that one service, but I cannot get any information about why or what's wrong. Any ideas on what I could try to get that information? Or what might be wrong? The unhandled System.ServiceModel.EndpointNotFoundException I get when running my client is: Could not connect to net.tcp://localhost:9005/ReportsService. The connection attempt lasted for a time span of 00:00:01.0937430. TCP error code 10061: No connection could be made because the target machine actively refused it 172.0.0.1:9005. . My host's config file contains: <!-- Snipped other services to simplify for you. --> <endpoint binding="netTcpBinding" bindingConfiguration="customTcpBinding" contract="ServiceContracts.IReportsService" /> <endpoint binding="netTcpBinding" bindingConfiguration="customTcpBinding" contract="ServiceContracts.IUpdateData" /> IReportService is the one I'm having trouble with. I get a proxy to IReportsService with the following code, where Server is the name of the hosting machine: return new ChannelFactory<IReportsService>("").CreateChannel(new EndpointAddress(string.Format("net.tcp://{0}:9005/ReportsService", Server))); My client config file contains: <system.serviceModel> <bindings> <netTcpBinding> <binding name="customTcpBinding" maxReceivedMessageSize="2147483647"> <readerQuotas maxNameTableCharCount="2147483647" maxStringContentLength="2147483647"/> <security mode="None"/> </binding> </netTcpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="ServiceBehavior"> <serviceMetadata httpGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="True" /> <serviceThrottling maxConcurrentCalls="30" maxConcurrentInstances="30" maxConcurrentSessions="1000" /> </behavior> </serviceBehaviors> </behaviors> <services> <!-- Snipped other services to simplify for you. --> <service behaviorConfiguration="ServiceBehavior" name="WcfService.ReportsService"> <endpoint address="ReportsService" binding="netTcpBinding" bindingConfiguration="customTcpBinding" contract="ServiceContracts.IReportsService" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="net.tcp://localhost:9005" /> </baseAddresses> </host> </service> <service behaviorConfiguration="ServiceBehavior" name="WcfService.UpdateData"> <endpoint address="UpdateData" binding="netTcpBinding" bindingConfiguration="customTcpBinding" contract="ServiceContracts.IUpdateData" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="net.tcp://localhost:9006" /> </baseAddresses> </host> </service> </services> </system.serviceModel> I've tried to keep things simple with the code snippets above, but if you would like to see more just ask and I'd be happy to provide anything that'll help.

  • Issues using a Fedex Webservice via WDSL/SOAP

  • jquery dynamic form plugin: adding nested field support

    - by goliatone
    Hi, Im using the jQuery dynamic form plugin, but i need support for nested field duplication. I would like some advice on how to modify the plugin to add such functionality. Im not a javascript/jQuery developer, so any advice on which route to take will be much appreciated. I can provide the plugin's code: /** * @author Stephane Roucheray * @extends jQuery */ jQuery.fn.dynamicForm = function (plusElmnt, minusElmnt, options){ var source = jQuery(this), minus = jQuery(minusElmnt), plus = jQuery(plusElmnt), template = source.clone(true), fieldId = 0, formFields = "input, checkbox, select, textarea", insertBefore = source.next(), clones = [], defaults = { duration:1000 }; // Extend default options with those provided options = $.extend(defaults, options); isPlusDescendentOfTemplate = source.find("*").filter(function(){ return this == plus.get(0); }); isPlusDescendentOfTemplate = isPlusDescendentOfTemplate.length > 0 ? true : false; function normalizeElmnt(elmnt){ elmnt.find(formFields).each(function(){ var nameAttr = jQuery(this).attr("name"), idAttr = jQuery(this).attr("id"); /* Normalize field name attributes */ if (!nameAttr) { jQuery(this).attr("name", "field" + fieldId + "[]"); } if (!/\[\]$/.exec(nameAttr)) { jQuery(this).attr("name", nameAttr + "[]"); } /* Normalize field id attributes */ if (idAttr) { /* Normalize attached label */ jQuery("label[for='"+idAttr+"']").each(function(){ jQuery(this).attr("for", idAttr + fieldId); }); jQuery(this).attr("id", idAttr + fieldId); } fieldId++; }); }; /* Hide minus element */ minus.hide(); /* If plus element is within the template */ if (isPlusDescendentOfTemplate) { function clickOnPlus(event){ var clone, currentClone = clones[clones.length -1] || source; event.preventDefault(); /* On first add, normalize source */ if (clones.length == 0) { normalizeElmnt(source); currentClone.find(minusElmnt).hide(); currentClone.find(plusElmnt).hide(); }else{ currentClone.find(plusElmnt).hide(); } /* Clone template and normalize it */ clone = template.clone(true).insertAfter(clones[clones.length - 1] || source); normalizeElmnt(clone); /* Normalize template id attribute */ if (clone.attr("id")) { clone.attr("id", clone.attr("id") + clones.length); } plus = clone.find(plusElmnt); minus = clone.find(minusElmnt); minus.get(0).removableClone = clone; minus.click(clickOnMinus); plus.click(clickOnPlus); if (options.limit && (options.limit - 2) > clones.length) { plus.show(); }else{ plus.hide(); } clones.push(clone); } function clickOnMinus(event){ event.preventDefault(); if (this.removableClone.effect && options.removeColor) { that = this; this.removableClone.effect("highlight", { color: options.removeColor }, options.duration, function(){that.removableClone.remove();}); } else { this.removableClone.remove(); } clones.splice(clones.indexOf(this.removableClone),1); if (clones.length == 0){ source.find(plusElmnt).show(); }else{ clones[clones.length -1].find(plusElmnt).show(); } } /* Handle click on plus */ plus.click(clickOnPlus); /* Handle click on minus */ minus.click(function(event){ }); }else{ /* If plus element is out of the template */ /* Handle click on plus */ plus.click(function(event){ var clone; event.preventDefault(); /* On first add, normalize source */ if (clones.length == 0) { normalizeElmnt(source); jQuery(minusElmnt).show(); } /* Clone template and normalize it */ clone = template.clone(true).insertAfter(clones[clones.length - 1] || source); if (clone.effect && options.createColor) { clone.effect("highlight", {color:options.createColor}, options.duration); } normalizeElmnt(clone); /* Normalize template id attribute */ if (clone.attr("id")) { clone.attr("id", clone.attr("id") + clones.length); } if (options.limit && (options.limit - 3) < clones.length) { plus.hide(); } clones.push(clone); }); /* Handle click on minus */ minus.click(function(event){ event.preventDefault(); var clone = clones.pop(); if (clones.length >= 0) { if (clone.effect && options.removeColor) { that = this; clone.effect("highlight", { color: options.removeColor, mode:"hide" }, options.duration, function(){clone.remove();}); } else { clone.remove(); } } if (clones.length == 0) { jQuery(minusElmnt).hide(); } plus.show(); }); } };

  • Problem with room/screen/menu controller in python game: old rooms are not removed from memory

    - by Jordan Magnuson
    I'm literally banging my head against a wall here (as in, yes, physically, at my current location, I am damaging my cranium). Basically, I've got a Python/Pygame game with some typical game "rooms", or "screens." EG title screen, high scores screen, and the actual game room. Something bad is happening when I switch between rooms: the old room (and its various items) are not removed from memory, or from my event listener. Not only that, but every time I go back to a certain room, my number of event listeners increases, as well as the RAM being consumed! (So if I go back and forth between the title screen and the "game room", for instance, the number of event listeners and the memory usage just keep going up and up. The main issue is that all the event listeners start to add up and really drain the CPU. I'm new to Python, and don't know if I'm doing something obviously wrong here, or what. I will love you so much if you can help me with this! Below is the relevant source code.

  • Java ThreadPoolExecutor getting stuck while using ArrayBlockingQueue

    - by Ravi Rao
    Hi, I'm working on some application and using ThreadPoolExecutor for handling various tasks. ThreadPoolExecutor is getting stuck after some duration. To simulate this in a simpler environment, I've written a simple code where I'm able to simulate the issue. import java.util.concurrent.ArrayBlockingQueue; import java.util.concurrent.RejectedExecutionHandler; import java.util.concurrent.ThreadPoolExecutor; import java.util.concurrent.TimeUnit; public class MyThreadPoolExecutor { private int poolSize = 10; private int maxPoolSize = 50; private long keepAliveTime = 10; private ThreadPoolExecutor threadPool = null; private final ArrayBlockingQueue&lt;Runnable&gt; queue = new ArrayBlockingQueue&lt;Runnable&gt;( 100000); public MyThreadPoolExecutor() { threadPool = new ThreadPoolExecutor(poolSize, maxPoolSize, keepAliveTime, TimeUnit.SECONDS, queue); threadPool.setRejectedExecutionHandler(new RejectedExecutionHandler() { @Override public void rejectedExecution(Runnable runnable, ThreadPoolExecutor threadPoolExecutor) { System.out .println(&quot;Execution rejected. Please try restarting the application.&quot;); } }); } public void runTask(Runnable task) { threadPool.execute(task); } public void shutDown() { threadPool.shutdownNow(); } public ThreadPoolExecutor getThreadPool() { return threadPool; } public void setThreadPool(ThreadPoolExecutor threadPool) { this.threadPool = threadPool; } public static void main(String[] args) { MyThreadPoolExecutor mtpe = new MyThreadPoolExecutor(); for (int i = 0; i &lt; 1000; i++) { final int j = i; mtpe.runTask(new Runnable() { @Override public void run() { System.out.println(j); } }); } } } Try executing this code a few times. It normally print outs the number on console and when all threads end, it exists. But at times, it finished all task and then is not getting terminated. The thread dump is as follows: MyThreadPoolExecutor [Java Application] MyThreadPoolExecutor at localhost:2619 (Suspended) Daemon System Thread [Attach Listener] (Suspended) Daemon System Thread [Signal Dispatcher] (Suspended) Daemon System Thread [Finalizer] (Suspended) Object.wait(long) line: not available [native method] ReferenceQueue&lt;T&gt;.remove(long) line: not available ReferenceQueue&lt;T&gt;.remove() line: not available Finalizer$FinalizerThread.run() line: not available Daemon System Thread [Reference Handler] (Suspended) Object.wait(long) line: not available [native method] Reference$Lock(Object).wait() line: 485 Reference$ReferenceHandler.run() line: not available Thread [pool-1-thread-1] (Suspended) Unsafe.park(boolean, long) line: not available [native method] LockSupport.park(Object) line: not available AbstractQueuedSynchronizer$ConditionObject.await() line: not available ArrayBlockingQueue&lt;E&gt;.take() line: not available ThreadPoolExecutor.getTask() line: not available ThreadPoolExecutor$Worker.run() line: not available Thread.run() line: not available Thread [pool-1-thread-2] (Suspended) Unsafe.park(boolean, long) line: not available [native method] LockSupport.park(Object) line: not available AbstractQueuedSynchronizer$ConditionObject.await() line: not available ArrayBlockingQueue&lt;E&gt;.take() line: not available ThreadPoolExecutor.getTask() line: not available ThreadPoolExecutor$Worker.run() line: not available Thread.run() line: not available Thread [pool-1-thread-3] (Suspended) Unsafe.park(boolean, long) line: not available [native method] LockSupport.park(Object) line: not available AbstractQueuedSynchronizer$ConditionObject.await() line: not available ArrayBlockingQueue&lt;E&gt;.take() line: not available ThreadPoolExecutor.getTask() line: not available ThreadPoolExecutor$Worker.run() line: not available Thread.run() line: not available Thread [pool-1-thread-4] (Suspended) Unsafe.park(boolean, long) line: not available [native method] LockSupport.park(Object) line: not available AbstractQueuedSynchronizer$ConditionObject.await() line: not available ArrayBlockingQueue&lt;E&gt;.take() line: not available ThreadPoolExecutor.getTask() line: not available ThreadPoolExecutor$Worker.run() line: not available Thread.run() line: not available Thread [pool-1-thread-6] (Suspended) Unsafe.park(boolean, long) line: not available [native method] LockSupport.park(Object) line: not available AbstractQueuedSynchronizer$ConditionObject.await() line: not available ArrayBlockingQueue&lt;E&gt;.take() line: not available ThreadPoolExecutor.getTask() line: not available ThreadPoolExecutor$Worker.run() line: not available Thread.run() line: not available Thread [pool-1-thread-8] (Suspended) Unsafe.park(boolean, long) line: not available [native method] LockSupport.park(Object) line: not available AbstractQueuedSynchronizer$ConditionObject.await() line: not available ArrayBlockingQueue&lt;E&gt;.take() line: not available ThreadPoolExecutor.getTask() line: not available ThreadPoolExecutor$Worker.run() line: not available Thread.run() line: not available Thread [pool-1-thread-5] (Suspended) Unsafe.park(boolean, long) line: not available [native method] LockSupport.park(Object) line: not available AbstractQueuedSynchronizer$ConditionObject.await() line: not available ArrayBlockingQueue&lt;E&gt;.take() line: not available ThreadPoolExecutor.getTask() line: not available ThreadPoolExecutor$Worker.run() line: not available Thread.run() line: not available Thread [pool-1-thread-10] (Suspended) Unsafe.park(boolean, long) line: not available [native method] LockSupport.park(Object) line: not available AbstractQueuedSynchronizer$ConditionObject.await() line: not available ArrayBlockingQueue&lt;E&gt;.take() line: not available ThreadPoolExecutor.getTask() line: not available ThreadPoolExecutor$Worker.run() line: not available Thread.run() line: not available Thread [pool-1-thread-9] (Suspended) Unsafe.park(boolean, long) line: not available [native method] LockSupport.park(Object) line: not available AbstractQueuedSynchronizer$ConditionObject.await() line: not available ArrayBlockingQueue&lt;E&gt;.take() line: not available ThreadPoolExecutor.getTask() line: not available ThreadPoolExecutor$Worker.run() line: not available Thread.run() line: not available Thread [pool-1-thread-7] (Suspended) Unsafe.park(boolean, long) line: not available [native method] LockSupport.park(Object) line: not available AbstractQueuedSynchronizer$ConditionObject.await() line: not available ArrayBlockingQueue&lt;E&gt;.take() line: not available ThreadPoolExecutor.getTask() line: not available ThreadPoolExecutor$Worker.run() line: not available Thread.run() line: not available Thread [DestroyJavaVM] (Suspended) C:\Program Files\Java\jre1.6.0_07\bin\javaw.exe (Jun 17, 2010 10:42:33 AM) In my actual application,ThreadPoolExecutor threads go in this state and then it stops responding.

  • How to avoid OLEDB converting "."s into "#"s in column names?

    - by Andrew Miner
    I'm using the ACE OLEDB driver to read from an Excel 2007 spreadsheet, and I'm finding that any '.' character in column names get converted to a '#' character. For example, if I have the following in a spreadsheet: Name Amt. Due Due Date Andrew 12.50 4/1/2010 Brian 20.00 4/12/2010 Charlie 1000.00 6/30/2010 the name of the second column would be reported as "Amt# Due" when read with the following code: OleDbConnection connection = new OleDbConnection( "Provider=Microsoft.ACE.OLEDB.12.0; Data Source={0}; " + "Extended Properties=\"Excel 12.0 Xml;HDR=YES;FMT=Delimited;IMEX=1\""); OldDbCommand command = new OleDbCommand("SELECT * FROM MyTable", connection); OleDbReader dataReader = command.ExecuteReader(); System.Console.WriteLine(dataReader.GetName(1)); I've read through all the documentation I can find and I haven't found anything which even mentions that this will happen. Has anyone run into this before? Is there a way to fix this behavior?

  • running multi threads in Java

    - by owca
    My task is to simulate activity of couple of persons. Each of them has few activities to perform in some random time: fast (0-5s), medium(5-10s), slow(10-20s) and very slow(20-30s). Each person performs its task independently in the same time. At the beginning of new task I should print it's random time, start the task and then after time passes show next task's time and start it. I've written run() function that counts time, but now it looks like threads are done one after another and not in the same time or maybe they're just printed in this way. public class People{ public static void main(String[] args){ Task tasksA[]={new Task("washing","fast"), new Task("reading","slow"), new Task("shopping","medium")}; Task tasksM[]={new Task("sleeping zzzzzzzzzz","very slow"), new Task("learning","slow"), new Task(" :** ","slow"), new Task("passing an exam","slow") }; Task tasksJ[]={new Task("listening music","medium"), new Task("doing nothing","slow"), new Task("walking","medium") }; BusyPerson friends[]={ new BusyPerson("Alice",tasksA), new BusyPerson("Mark",tasksM), new BusyPerson("John",tasksJ)}; System.out.println("STARTING....................."); for(BusyPerson f: friends) (new Thread(f)).start(); System.out.println("DONE........................."); } } class Task { private String task; private int time; private Task[]tasks; public Task(String t, String s){ task = t; Speed speed = new Speed(); time = speed.getSpeed(s); } public Task(Task[]tab){ Task[]table=new Task[tab.length]; for(int i=0; i < tab.length; i++){ table[i] = tab[i]; } this.tasks = table; } } class Speed { private static String[]hows = {"fast","medium","slow","very slow"}; private static int[]maxs = {5000, 10000, 20000, 30000}; public Speed(){ } public static int getSpeed( String speedString){ String s = speedString; int up_limit=0; int down_limit=0; int time=0; //get limits of time for(int i=0; i<hows.length; i++){ if(s.equals(hows[i])){ up_limit = maxs[i]; if(i>0){ down_limit = maxs[i-1]; } else{ down_limit = 0; } } } //get random time within the limits Random rand = new Random(); time = rand.nextInt(up_limit) + down_limit; return time; } } class BusyPerson implements Runnable { private String name; private Task[] person_tasks; private BusyPerson[]persons; public BusyPerson(String s, Task[]t){ name = s; person_tasks = t; } public BusyPerson(BusyPerson[]tab){ BusyPerson[]table=new BusyPerson[tab.length]; for(int i=0; i < tab.length; i++){ table[i] = tab[i]; } this.persons = table; } public void run() { int time = 0; double t1=0; for(Task t: person_tasks){ t1 = (double)t.time/1000; System.out.println(name+" is...

  • Big smart ViewModels, dumb Views, and any model, the best MVVM approach?

    - by Edward Tanguay
    The following code is a refactoring of my previous MVVM approach (Fat Models, skinny ViewModels and dumb Views, the best MVVM approach?) in which I moved the logic and INotifyPropertyChanged implementation from the model back up into the ViewModel. This makes more sense, since as was pointed out, you often you have to use models that you either can't change or don't want to change and so your MVVM approach should be able to work with any model class as it happens to exist. This example still allows you to view the live data from your model in design mode in Visual Studio and Expression Blend which I think is significant since you could have a mock data store that the designer connects to which has e.g. the smallest and largest strings that the UI can possibly encounter so that he can adjust the design based on those extremes. Questions: I'm a bit surprised that I even have to "put a timer" in my ViewModel since it seems like that is a function of INotifyPropertyChanged, it seems redundant, but it was the only way I could get the XAML UI to constantly (once per second) reflect the state of my model. So it would be interesting to hear anyone who may have taken this approach if you encountered any disadvantages down the road, e.g. with threading or performance. The following code will work if you just copy the XAML and code behind into a new WPF project. XAML: <Window x:Class="TestMvvm73892.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:TestMvvm73892" Title="Window1" Height="300" Width="300"> <Window.Resources> <ObjectDataProvider x:Key="DataSourceCustomer" ObjectType="{x:Type local:CustomerViewModel}" MethodName="GetCustomerViewModel"/> </Window.Resources> <DockPanel DataContext="{StaticResource DataSourceCustomer}"> <StackPanel DockPanel.Dock="Top" Orientation="Horizontal"> <TextBlock Text="{Binding Path=FirstName}"/> <TextBlock Text=" "/> <TextBlock Text="{Binding Path=LastName}"/> </StackPanel> <StackPanel DockPanel.Dock="Top" Orientation="Horizontal"> <TextBlock Text="{Binding Path=TimeOfMostRecentActivity}"/> </StackPanel> </DockPanel> </Window> Code Behind: using System; using System.Windows; using System.ComponentModel; using System.Threading; namespace TestMvvm73892 { public partial class Window1 : Window { public Window1() { InitializeComponent(); } } //view model public class CustomerViewModel : INotifyPropertyChanged { private string _firstName; private string _lastName; private DateTime _timeOfMostRecentActivity; private Timer _timer; public string FirstName { get { return _firstName; } set { _firstName = value; this.RaisePropertyChanged("FirstName"); } } public string LastName { get { return _lastName; } set { _lastName = value; this.RaisePropertyChanged("LastName"); } } public DateTime TimeOfMostRecentActivity { get { return _timeOfMostRecentActivity; } set { _timeOfMostRecentActivity = value; this.RaisePropertyChanged("TimeOfMostRecentActivity"); } } public CustomerViewModel() { _timer = new Timer(CheckForChangesInModel, null, 0, 1000); } private void CheckForChangesInModel(object state) { Customer currentCustomer = CustomerViewModel.GetCurrentCustomer(); MapFieldsFromModeltoViewModel(currentCustomer, this); } public static CustomerViewModel GetCustomerViewModel() { CustomerViewModel customerViewModel = new CustomerViewModel(); Customer currentCustomer = CustomerViewModel.GetCurrentCustomer(); MapFieldsFromModeltoViewModel(currentCustomer, customerViewModel); return customerViewModel; } public static void MapFieldsFromModeltoViewModel(Customer model, CustomerViewModel viewModel) { viewModel.FirstName = model.FirstName; viewModel.LastName = model.LastName; viewModel.TimeOfMostRecentActivity = model.TimeOfMostRecentActivity; } public static Customer GetCurrentCustomer() { return Customer.GetCurrentCustomer(); } //INotifyPropertyChanged implementation public event PropertyChangedEventHandler PropertyChanged; private void RaisePropertyChanged(string property) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(property)); } } } //model public class Customer { public string FirstName { get; set; } public string LastName { get; set; } public DateTime TimeOfMostRecentActivity { get; set; } public static Customer GetCurrentCustomer() { return new Customer { FirstName = "Jim", LastName = "Smith", TimeOfMostRecentActivity = DateTime.Now }; } } }

  • OpenGL basics: calling glDrawElements once per object

    - by Bethor
    Hi all, continuing on from my explorations of the basics of OpenGL (see this question), I'm trying to figure out the basic principles of drawing a scene with OpenGL. I am trying to render a simple cube repeated n times in every direction. My method appears to yield terrible performance : 1000 cubes brings performance below 50fps (on a QuadroFX 1800, roughly a GeForce 9600GT). My method for drawing these cubes is as follows: done once: set up a vertex buffer and array buffer containing my cube vertices in model space set up an array buffer indexing the cube for drawing as 12 triangles done for each frame: update uniform values used by the vertex shader to move all cubes at once done for each cube, for each frame: update uniform values used by the vertex shader to move each cube to its position call glDrawElements to draw the positioned cube Is this a sane method ? If not, how does one go about something like this ? I'm guessing I need to minimize calls to glUniform, glDrawElements, or both, but I'm not sure how to do that. Full code for my little test : (depends on gletools and pyglet) I'm aware that my init code (at least) is really ugly; I'm concerned with the rendering code for each frame right now, I'll move to something a little less insane for the creation of the vertex buffers and such later on. import pyglet from pyglet.gl import * from pyglet.window import key from numpy import deg2rad, tan from gletools import ShaderProgram, FragmentShader, VertexShader, GeometryShader vertexData = [-0.5, -0.5, -0.5, 1.0, -0.5, 0.5, -0.5, 1.0, 0.5, -0.5, -0.5, 1.0, 0.5, 0.5, -0.5, 1.0, -0.5, -0.5, 0.5, 1.0, -0.5, 0.5, 0.5, 1.0, 0.5, -0.5, 0.5, 1.0, 0.5, 0.5, 0.5, 1.0] elementArray = [2, 1, 0, 1, 2, 3,## back face 4, 7, 6, 4, 5, 7,## front face 1, 3, 5, 3, 7, 5,## top face 2, 0, 4, 2, 4, 6,## bottom face 1, 5, 4, 0, 1, 4,## left face 6, 7, 3, 6, 3, 2]## right face def toGLArray(input): return (GLfloat*len(input))(*input) def toGLushortArray(input): return (GLushort*len(input))(*input) def initPerspectiveMatrix(aspectRatio = 1.0, fov = 45): frustumScale = 1.0 / tan(deg2rad(fov) / 2.0) fzNear = 0.5 fzFar = 300.0 perspectiveMatrix = [frustumScale*aspectRatio, 0.0 , 0.0 , 0.0 , 0.0 , frustumScale, 0.0 , 0.0 , 0.0 , 0.0 , (fzFar+fzNear)/(fzNear-fzFar) , -1.0, 0.0 , 0.0 , (2*fzFar*fzNear)/(fzNear-fzFar), 0.0 ] return perspectiveMatrix class ModelObject(object): vbo = GLuint() vao = GLuint() eao = GLuint() initDone = False verticesPool = [] indexPool = [] def __init__(self, vertices, indexing): super(ModelObject, self).__init__() if not ModelObject.initDone: glGenVertexArrays(1, ModelObject.vao) glGenBuffers(1, ModelObject.vbo) glGenBuffers(1, ModelObject.eao) glBindVertexArray(ModelObject.vao) initDone = True self.numIndices = len(indexing) self.offsetIntoVerticesPool = len(ModelObject.verticesPool) ModelObject.verticesPool.extend(vertices) self.offsetIntoElementArray = len(ModelObject.indexPool) ModelObject.indexPool.extend(indexing) glBindBuffer(GL_ARRAY_BUFFER, ModelObject.vbo) glEnableVertexAttribArray(0) #position glVertexAttribPointer(0, 4, GL_FLOAT, GL_FALSE, 0, 0) glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, ModelObject.eao) glBufferData(GL_ARRAY_BUFFER, len(ModelObject.verticesPool)*4, toGLArray(ModelObject.verticesPool), GL_STREAM_DRAW) glBufferData(GL_ELEMENT_ARRAY_BUFFER, len(ModelObject.indexPool)*2, toGLushortArray(ModelObject.indexPool), GL_STREAM_DRAW) def draw(self): glDrawElements(GL_TRIANGLES, self.numIndices, GL_UNSIGNED_SHORT, self.offsetIntoElementArray) class PositionedObject(object): def __init__(self, mesh, pos, objOffsetUf): super(PositionedObject, self).__init__() self.mesh = mesh self.pos = pos self.objOffsetUf = objOffsetUf def draw(self): glUniform3f(self.objOffsetUf, self.pos[0], self.pos[1], self.pos[2]) self.mesh.draw() w = 800 h = 600 AR = float(h)/float(w) window = pyglet.window.Window(width=w, height=h, vsync=False) window.set_exclusive_mouse(True) pyglet.clock.set_fps_limit(None) ## input forward = [False] left = [False] back = [False] right = [False] up = [False] down = [False] inputs = {key.Z: forward, key.Q: left, key.S: back, key.D: right, key.UP: forward, key.LEFT: left, key.DOWN: back, key.RIGHT: right, key.PAGEUP: up, key.PAGEDOWN: down} ## camera camX = 0.0 camY = 0.0 camZ = -1.0 def simulate(delta): global camZ, camX, camY scale = 10.0 move = scale*delta if forward[0]: camZ += move if back[0]: camZ += -move if left[0]: camX += move if right[0]: camX += -move if up[0]: camY += move if down[0]: camY += -move pyglet.clock.schedule(simulate) @window.event def on_key_press(symbol, modifiers): global forward, back, left, right, up, down if symbol in inputs.keys(): inputs[symbol][0] = True @window.event def on_key_release(symbol, modifiers): global forward, back, left, right, up, down if symbol in inputs.keys(): inputs[symbol][0] = False ## uniforms for shaders camOffsetUf = GLuint() objOffsetUf = GLuint() perspectiveMatrixUf = GLuint() camRotationUf = GLuint() program = ShaderProgram( VertexShader(''' #version 330 layout(location = 0) in vec4 objCoord;

  • Problem using Hibernate-Search

    - by KCore
    Hi, I am using hibernate search for my application. It is well configured and running perfectly till some time back, when it stopped working suddenly. The reason according to me being the number of my model (bean) classes. I have some 90 classes, which I add to my configuration, while building my Hibernate Configuration. When, I disable hibernate search (remove the search annotations and use Configuration instead of AnnotationsConfiguration), I try to start my application, it Works fine. But,the same app when I enable search, it just hangs up. I tried debugging and found the exact place where it hangs. After adding all the class to my AnnotationsConfiguration object, when I say cfg.buildSessionfactory(), It never comes out of that statement. (I have waited for hours!!!) Also when I decrease the number of my model classes (like say to half i.e. 50) it comes out of that statement and the application works fine.. Can Someone tell why is this happening?? My versions of hibernate are: hibernate-core-3.3.1.GA.jar hibernate-annotations-3.4.0.GA.jar hibernate-commons-annotations-3.1.0.GA.jar hibernate-search-3.1.0.GA.jar Also if need to avoid using AnnotationsConfiguration, I read that I need to configure the search event listeners explicitly.. can anyone list all the neccessary listeners and their respective classes? (I tried the standard ones given in Hibernate Search books, but they give me ClassNotFound exception and I have all the neccesarty libs in classpath) Here are the last few lines of hibernate trace I managed to pull : 16:09:32,814 INFO AnnotationConfiguration:369 -

  • Communication with HyperTerminal [ QT and WINApi ]

    Hi! I write program to communicate with modem (it useing Hayes commands) and this is working. GUI is programmed with QT, but communication with COM port is write with winapi library. I have problem when I want to send with my program message from one computer to another, i can't send Polish chars (they are repleaced by '?'), how can I fix it ? Does anyone have idea ??

  • Base64 Encode String in VBScript

    - by Patrick Cuff
    I have a web service load driver that's a Windows Script File (WSF), that includes some VBScript and JavaScript files. My web service requires that the incoming message is base64 encoded. I currently have a VBScript function that does this, but it's very inefficient (memory intensive, mostly due to VBScripts awful string concatenation) [Aside; Yes, I've seen Jeff's latest blog post. The concatenation is happening in a loop across messages that are 1,000's to 10,000's bytes in size.] I've tried using some custom string concatenation routines; one using an array and one using ADODB.Stream. These help, a little, but I think it would help more if I had some other way of encoding the message rather than via my own VBS function. Is there some other way of encoding my message, preferebly using native Windows methods?

  • HttpWebRequest Cookie weirdness

    I'm sure I must be doing something wrong. But can't for the life of me figure out what is going on. I have a problem where it seems that the HttpWebRequest class in the framework is not correctly parsing the cookies from a web response. I'm using Fiddler to see what is going on and after making a request, the headers of the response look as such: HTTP/1.1 200 Ok Connection: close Date: Wed, 14 Jan 2009 18:20:31 GMT Server: Microsoft-IIS/6.0 P3P: policyref="/w3c/p3p.xml", CP="CAO DSP IND COR ADM CONo CUR CUSi DEV PSA PSD DELi OUR COM NAV PHY ONL PUR UNI" Set-Cookie: user=v.5,0,EX01E508801E$97$2E401000t$1BV6$A1$EC$104$A1$EC$104$A1$EC$104$21O001000$1E31!90$7CP$AE$3F$F3$D8$19o$BC$1Cd$23; Domain=.thedomain.com; path=/ Set-Cookie: minfo=v.4,EX019ECD28D6k$A3$CA$0C$CE$A2$D6$AD$D4!2$8A$EF$E8n$91$96$E1$D7$C8$0F$98$AA$ED$DC$40V$AB$9C$C1$9CF$C9$C1zIF$3A$93$C6$A7$DF$A1$7E$A7$A1$A8$BD$A6$94c$D5$E8$2F$F4$AF$A2$DF$80$89$BA$BBd$F6$2C$B6$A8; expires=Sunday, 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Set-Cookie: accttype=v.2,3,1,EX017E651B09k$A3$CA$0C$DB$A2$CB$AD$D9$8A$8C$EF$E8t$91$90$E1$DC$C89$98$AA$E0$DC$40O$A8$A4$C1$9C; expires=Sunday, 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Set-Cookie: tpid=v.1,20001; expires=Sunday, 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Set-Cookie: MC1=GUID=541977e04a341a2a4f4cdaaf49615487; expires=Sunday, 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Set-Cookie: linfo=v.4,EQC|0|0|255|1|0||||||||0|0|0||0|0|0|-1|-1; expires=Sunday, 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Set-Cookie: group=v.1,0; expires=Sunday, 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Content-Type: text/html But when I look at the response.Cookies, I see far more cookies that I am expecting, with values of different cookies being split up into different cookies. Manually getting the headers seems to result in more wierdness eg: the code foreach(string cookie in response.Headers.GetValues("Set-Cookie")) { Console.WriteLine("Cookie found: " + cookie); } produces the output: Cookie found: user=v.5 Cookie found: 0 Cookie found: EX01E508801E$97$2E401000t$1BV6$A1$EC$104$A1$EC$104$A1$EC$104$21O00 1000$1E31!90$7CP$AE$3F$F3$D8$19o$BC$1Cd$23; Domain=.thedomain.com; path=/ Cookie found: minfo=v.4 Cookie found: EX019ECD28D6k$A3$CA$0C$CE$A2$D6$AD$D4!2$8A$EF$E8n$91$96$E1$D7$C8$0 F$98$AA$ED$DC$40V$AB$9C$C1$9CF$C9$C1zIF$3A$93$C6$A7$DF$A1$7E$A7$A1$A8$BD$A6$94c$ D5$E8$2F$F4$AF$A2$DF$80$89$BA$BBd$F6$2C$B6$A8; expires=Sunday Cookie found: 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Cookie found: accttype=v.2 Cookie found: 3 Cookie found: 1 Cookie found: EX017E651B09k$A3$CA$0C$DB$A2$CB$AD$D9$8A$8C$EF$E8t$91$90$E1$DC$C89 $98$AA$E0$DC$40O$A8$A4$C1$9C; expires=Sunday Cookie found: 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Cookie found: tpid=v.1 Cookie found: 20001; expires=Sunday Cookie found: 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Cookie found: MC1=GUID=541977e04a341a2a4f4cdaaf49615487; expires=Sunday Cookie found: 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Cookie found: linfo=v.4 Cookie found: EQC|0|0|255|1|0||||||||0|0|0||0|0|0|-1|-1; expires=Sunday Cookie found: 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Cookie found: group=v.1 Cookie found: 0; expires=Sunday Cookie found: 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ as you can see - the first cookie in the list raw response: Set-Cookie: user=v.5,0,EX01E508801 is getting split into: Cookie found: user=v.5 Cookie found: 0 Cookie found: EX01E508801E$.......... So - what's going on here? Am I wrong? Is the HttpWebRequest class incorrectly parsing the http headers? Is the webserver that it spitting out the requests producing invalid http headers?

  • jQuery Toggle with Cookie

    - by Cameron
    I have the following toggle system, but I want it to remember what was open/closed using the jQuery cookie plugin. So for example if I open a toggle and then navigate away from the page, when I come back it should be still open. This is code I have so far, but it's becoming rather confusing, some help would be much appreciated thanks. jQuery.cookie = function (name, value, options) { if (typeof value != 'undefined') { options = options || {}; if (value === null) { value = ''; options = $.extend({}, options); options.expires = -1; } var expires = ''; if (options.expires && (typeof options.expires == 'number' || options.expires.toUTCString)) { var date; if (typeof options.expires == 'number') { date = new Date(); date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000)); } else { date = options.expires; } expires = '; expires=' + date.toUTCString(); } var path = options.path ? '; path=' + (options.path) : ''; var domain = options.domain ? '; domain=' + (options.domain) : ''; var secure = options.secure ? '; secure' : ''; document.cookie = [name, '=', encodeURIComponent(value), expires, path, domain, secure].join(''); } else { var cookieValue = null; if (document.cookie && document.cookie != '') { var cookies = document.cookie.split(';'); for (var i = 0; i < cookies.length; i++) { var cookie = jQuery.trim(cookies[i]); if (cookie.substring(0, name.length + 1) == (name + '=')) { cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); break; } } } return cookieValue; } }; // var showTop = $.cookie('showTop'); if ($.cookie('showTop') == 'collapsed') { $(".toggle_container").hide(); $(".trigger").toggle(function () { $(this).addClass("active"); }, function () { $(this).removeClass("active"); }); $(".trigger").click(function () { $(this).next(".toggle_container").slideToggle("slow,"); }); } else { $(".toggle_container").show(); $(".trigger").toggle(function () { $(this).addClass("active"); }, function () { $(this).removeClass("active"); }); $(".trigger").click(function () { $(this).next(".toggle_container").slideToggle("slow,"); }); }; $(".trigger").click(function () { if ($(".toggle_container").is(":hidden")) { $(this).next(".toggle_container").slideToggle("slow,"); $.cookie('showTop', 'expanded'); } else { $(this).next(".toggle_container").slideToggle("slow,"); $.cookie('showTop', 'collapsed'); } return false; }); and this is a snippet of the HTML it works with: <li> <label for="small"><input type="checkbox" id="small" /> Small</label> <a class="trigger" href="#">Toggle</a> <div class="toggle_container"> <p class="funding"><strong>Funding</strong></p> <ul class="childs"> <li class="child"> <label for="fully-funded1"><input type="checkbox" id="fully-funded1" /> Fully Funded</label> <a class="trigger" href="#">Toggle</a> <div class="toggle_container"> <p class="days"><strong>Days</strong></p> <ul class="days clearfix"> <li><label for="1pre16">Pre 16</label> <input type="text" id="1pre16" /></li> <li><label for="2post16">Post 16</label> <input type="text" id="2post16" /></li> <li><label for="3teacher">Teacher</label> <input type="text" id="3teacher" /></li> </ul> </div> </li>

  • WP: AesManaged encryption vs. mcrypt_encrypt

    - by invalidusername
    I'm trying to synchronize my encryption and decryption methods between C# and PHP but something seems to be going wrong. In the Windows Phone 7 SDK you can use AESManaged to encrypt your data I use the following method: public static string EncryptA(string dataToEncrypt, string password, string salt) { AesManaged aes = null; MemoryStream memoryStream = null; CryptoStream cryptoStream = null; try { //Generate a Key based on a Password, Salt and HMACSHA1 pseudo-random number generator Rfc2898DeriveBytes rfc2898 = new Rfc2898DeriveBytes(password, Encoding.UTF8.GetBytes(salt)); //Create AES algorithm with 256 bit key and 128-bit block size aes = new AesManaged(); aes.Key = rfc2898.GetBytes(aes.KeySize / 8); aes.IV = new byte[] { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }; // rfc2898.GetBytes(aes.BlockSize / 8); // to check my results against those of PHP var blaat1 = Convert.ToBase64String(aes.Key); var blaat2 = Convert.ToBase64String(aes.IV); //Create Memory and Crypto Streams memoryStream = new MemoryStream(); cryptoStream = new CryptoStream(memoryStream, aes.CreateEncryptor(), CryptoStreamMode.Write); //Encrypt Data byte[] data = Encoding.Unicode.GetBytes(dataToEncrypt); cryptoStream.Write(data, 0, data.Length); cryptoStream.FlushFinalBlock(); //Return Base 64 String string result = Convert.ToBase64String(memoryStream.ToArray()); return result; } finally { if (cryptoStream != null) cryptoStream.Close(); if (memoryStream != null) memoryStream.Close(); if (aes != null) aes.Clear(); } } I solved the problem of generating the Key. The Key and IV are similar as those on the PHP end. But then the final step in the encryption is going wrong. here is my PHP code <?php function pbkdf2($p, $s, $c, $dk_len, $algo = 'sha1') { // experimentally determine h_len for the algorithm in question static $lengths; if (!isset($lengths[$algo])) { $lengths[$algo] = strlen(hash($algo, null, true)); } $h_len = $lengths[$algo]; if ($dk_len > (pow(2, 32) - 1) * $h_len) { return false; // derived key is too long } else { $l = ceil($dk_len / $h_len); // number of derived key blocks to compute $t = null; for ($i = 1; $i <= $l; $i++) { $f = $u = hash_hmac($algo, $s . pack('N', $i), $p, true); // first iterate for ($j = 1; $j < $c; $j++) { $f ^= ($u = hash_hmac($algo, $u, $p, true)); // xor each iterate } $t .= $f; // concatenate blocks of the derived key } return substr($t, 0, $dk_len); // return the derived key of correct length } } $password = 'test'; $salt = 'saltsalt'; $text = "texttoencrypt"; #$iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC); #echo $iv_size . '<br/>'; #$iv = mcrypt_create_iv($iv_size, MCRYPT_RAND); #print_r (mcrypt_list_algorithms()); $iv = "\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00"; $key = pbkdf2($password, $salt, 1000, 32); echo 'key: ' . base64_encode($key) . '<br/>'; echo 'iv: ' . base64_encode($iv) . '<br/>'; echo '<br/><br/>'; function addpadding($string, $blocksize = 32){ $len = strlen($string); $pad = $blocksize - ($len % $blocksize); $string .= str_repeat(chr($pad), $pad); return $string; } echo 'text: ' . $text . '<br/>'; echo 'text: ' . addpadding($text) . '<br/>'; // -- works till here $crypttext = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, $text, MCRYPT_MODE_CBC, $iv); echo '1.' . $crypttext . '<br/>'; $crypttext = base64_encode($crypttext); echo '2.' . $crypttext . '<br/>'; $crypttext = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, addpadding($text), MCRYPT_MODE_CBC, $iv); echo '1.' . $crypttext . '<br/>'; $crypttext = base64_encode($crypttext); echo '2.' . $crypttext . '<br/>'; ?> So to point out, the Key and IV look similar on both .NET and PHP, but something seems to be going wrong in the final call when executing mcrypt_encrypt(). The end result, the encrypted string, differs from .NET. Can anybody tell me what i'm doing wrong. As far as i can see everything should be correct. Thank you! EDIT: Additional information on the AESManaged object in .NET Keysize = 256 Mode = CBC Padding = PKCS7

  • Convert PDF to Image Batch

    I am working on a solution where I can convert pdf files to images. I am using the following example from codeproject: http://www.codeproject.com/Articles/317700/Convert-a-PDF-into-a-series-of-images-using-Csharp?msg=4134859#xx4134859xx now I tried with the following code to generate from more then 1000 pdf files new images: using Cyotek.GhostScript; using Cyotek.GhostScript.PdfConversion; using System; using System.Collections.Generic; using System.Drawing; using System.IO; using System.Linq; using System.Text; using System.Threading.Tasks; namespace RefClass_PDF2Image { class Program { static void Main(string[] args) { string outputPath = Properties.Settings.Default.outputPath; string pdfPath = Properties.Settings.Default.pdfPath; if (!Directory.Exists(outputPath)) { Console.WriteLine("Der angegebene Pfad " + outputPath + " für den Export wurde nicht gefunden.
