• Cross domain cookie tracking

  - by Jon

  Hi, The company I work for has four domains and I'm trying to set up the cookies, so one cookie can be generated and tracked across all the domains. From reading various posts on here I thought it was possible. I've set up a sub domain on one site, to serve a cookie and 1*1 pixel image to all four sites. But I can't get this working on the other sites. If anyone can clarify that: Its possible? If I'm missing something obvious or a link to a good example? I'm trying to do this server side with PHP. Thanks

• What design patterns are used in diagramming tools?

  - by TheMachineCharmer

  Diagram.net is good diagramming tool. I need to understand what design patterns are used by this tool so that I can understand how it works. What design patterns are used in this tool? What design patterns are generally used for diagramming tools? I would also like to know how can I use this to develop very simple diagramming tool (Only rectangular nodes and straight links).

• cross domain access in iframe from parent to child

  - by Aparna

  Hi, Could someone please help me with this- I've 2 applications AAA and BBB. The homepage of AAA contains an iFrame which displays the application BBB. When I login to AAA, the same login details should be used to login to BBB(single signon) and on pageload of the homepage of AAA, homepage of BBB should also be loaded in the iFrame. I tried to use javascript to access the form elements of login page of BBB to enter the login data and submit. But the browser gives me a 'Access is denied' error. I did a little reading and came to know that cross- domain communication is not allowed by the browser. Could someone tell me how i can go about achieving this?

• android call log like design

  - by Alxandr

  I'm trying to create a design for a list that looks like (and mostly behaves like) the call log, like shown here: I don't need all the design, but what I'm trying to achieve is the two-columned design with the splitter in-between, and the behavior that if I click on the main item (the left part) one thing happens (in this case, you open some details about the call), and if you press the outer right part something else happens (you call the contact). I'm pretty new to android, but I've managed to do most of the designs I wanted so far, so I don't need the entire layout for this one, only the part that does the splitting and the splitter. And if possible it would be nice to know how to map the clicks appropriately, though I think I might be able to find that out by my self.

• Best design for generating code from an AST?

  - by Sam Washburn

  I'm working on a pretty complex DSL that I want to compile down into a few high level languages. The whole process has been a learning experience. The compiler is written in java. I was wondering if anyone knew a best practice for the design of the code generator portion. I currently have everything parsed into an abstract syntax tree. I was thinking of using a template system, but I haven't researched that direction too far yet as I would like to hear some wisdom first from stack overflow. Thanks!

• Alternative design for a synonyms table?

  - by Majid

  I am working on an app which is to suggest alternative words/phrases for input text. I have doubts about what might be a good design for the synonyms table. Design considerations: number of synonyms is variable, i.e. football has one synonym (soccer), but in particular has two (particularly, specifically) if football is a synonym to soccer, the relation exists in the opposite direction as well. our goal is to query a word and find its synonyms we want to keep the table small and make adding new words easy What comes to my mind is a two column design with col a = word and col b = delimited list of synonyms Is there any better alternative? What about using two tables, one for words and the other for relations?

• View centric design with Django

  - by wishi_

  Hi! I'm relatively new to Django and I'm designing a website that primarily needs usability experience, speaking of optimized CSS, HTML5 and UI stuff. It's very easy to use Django for data/Model centric design. Just designing a couple of Python classes and ./manage.py syncdb - there's your Model. But I'm dealing with a significant amount of View centric challenges. (Different user classes, different tasks, different design challenges.) The official Django tutorial cursorily goes through using a "Template". Is there any Design centric guide for Django, or a set of Templates that are ready and useable? I don't want to start from scratch using JS, HTML5, Ajax and everything. From the Model layer perspective Django is very rapid and delivering a working base system. I wonder whether there's something like that for the Views.

Please help; I have spent the whole day trying to figure this out. Am using ibatis 3.0 and am new to ibatis. Regards Josh

• Using $.getJSON to perform cross domain request problem.

  - by Ahmed

  I'm using the following code to make cross domain request using $.getJSON, request completed but with errors, I cannot exactly detect what is the thrown error. Based on callback param of request value I route it to a certain method which retrieves required JSON data. $.getJSON("http://wthsrvr:45452/Handler.ashx/?Callback=DocumentReadStatus", { userID: vuserID, documentID: vdocumentID, format: "json" }, function(result) { if (result.readStatus == '1') { alert("ACCEPTED"); } else if (result.readStatus == '0') { alert("NOT ACCEPTED"); } else { alert(result.readStatus); } }); FYI: while development of this locally, everything worked fine, but after solution deployment to server and trying to do the same, I got that problem. Also, I tried the same functionality with web service, I got the same problem while calling web service from server. I'm using ajaxSetup to detect thrown errors. $.ajaxSetup({ "error": function(XMLHttpRequest, textStatus, errorThrown) { alert("textStatus: " + textStatus); alert("errorThrown: " + errorThrown); alert("responseText: " + XMLHttpRequest.responseText); } });

• How can I prevent application domain stealing?

  - by dr jerry

  I'm in the process of making a javascript application and I want to bring that online, lets call it mydesign. I'm living in the Netherlands so mydesign.nl can be mine. Now is mydesign.com available for sale by some domain broker sales bastards. And those bastards don't accept a first bid lower than 1000$ which is a about ten times of the budget I'm willing to pay. So far so good, it's a sick business model but it's there. Now lets imagine that mydesign.nl is a huge success in the Netherlands and I'm makin tons of profits out of advertisements and other things I'm not yet aware of (I know entering the lotery gives a better chance of earning money, but lets just imagine). Is there a way (licence, legal or otherwise) to prevent the sick owners of mydesign.com to download and steal my javascript app and deploy it on their own site and take the profits of my app?

• Proper design a Model-Controller in Cocoa?

  - by legege

  Hi, I'm trying to design a simple Cocoa application and I would like to have a clear and easy to understand software architecture. Of course, I'm using a basic MVC design and my question concerns the Model layer. For my application, the Model represents data fetched on the Internet with a XML-RPC API. I'm planning to use Core Data to represent a locally fetched version. How should the data be loaded initially? I'm reading the Cocoa Design Pattern book, and they talk about a Model-Controller that is centric to the Model. How would that be done? Thanks!

• C++ domain specific embedded language operators

  - by aaa

  hi. In numerical oriented languages (Matlab, Fortran) range operator and semantics is very handy when working with multidimensional data. For example: A(i:j,k,:n) // represents two-dimensional slice B(i:j,0:n) of A at index k unfortunately C++ does not have range operator (:). of course it can be emulated using range/slice functor, but semantics is less clean than Matlab. I am prototyping matrix/tensor domain language in C++ and am wondering if there any options to reproduce range operator. I still would like to rely on C++/prprocessor framework exclusively. So far I have looked through boost wave which might be an suitable option. is there any other means to introduce new operators to C++ DSL?

• Design pattern for mouse interaction

  - by mike

  I need some opinions on what is the "ideal" design pattern for a general mouse interaction. Here the simplified problem. I have a small 3d program (QT and openGL) and I use the mouse for interaction. Every interaction is normally not only a single function call, it is mostly performed by up to 3 function calls (initiate, perform, finalize). For example, camera rotation: here the initial function call will deliver the current first mouse position, whereas the performing function calls will update the camera etc. However, for only a couple of interactions, hardcoding these (inside MousePressEvent, MouseReleaseEvent MouseMoveEvent or MouseWheelEvent etc) is not a big deal, but if I think about a more advanced program (e.g 20 or more interactions) then a proper design is needed. Therefore, how would you design such a interactions inside QT. I hope I made my problem clear enough, otherwise don't bother complain :-) Thanks

• Good workflow for website design

  - by Olav

  I would like some idea about a good workflow for Website Design, with a high degree of "offshoring" (Elance, Odesk etc.). I would to do as much as possible "pre production", with client input, ideas etc. stored in IA diagrams, wireframe mockups etc. in something like a Wiki. Also a like the idea about having different people come up with different design proposals. Wouldlike to have some ideas of costs of different phases and tasks ($, %, hours). With Design I mean roughly the aspects of a site that can be done with client-side tools, especially XHTML and CSS. What other tools should I use than IA diagrams.

• Overriding setter on domain class in grails 1.1.2

  - by Pavel P

  I have following two domain classes in Grails 1.1.2: class A implements Serializable { MyEnumType myField Date fieldChanged void setMyField(MyEnumType val) { if (myField != null && myField != val) { myField = val fieldChanged = new Date() } } } class B extends A { List children void setMyField(MyEnumType val) { if (myField != null && myField != val) { myField = val fieldChanged = new Date() children.each { child -> child.myField = val } } } When I set B instance's myField, I get the setter into the cycle... myField = val line calls setter again instead of assiging the new value. Any hint how to override the setter correctly? Thanks

• AJAX XMLHttpRequest POST X-Domain

  - by Tom

  Hi Guys, I am sending an AJAX request using POST over X-Domain for a widget we are producing for our website. The problem we are facing is that this is getting blocked. My question is - for "modern browsers" [Chrome, Safari, FF, IE8] - it is my understanding that setting "Access-Control" headers Access-Control-Allow-Origin: http://www.test.com Access-Control-Allow-Methods: POST, GET, OPTIONS Access-Control-Allow-Headers: * Access-Control-Max-Age: 1728000 Will allow these "POST" requests to work ? But for IE7 we need to implement some "custom" JSONP solution? Am I correct in this ?

• cross domain DOM access and manipulation in Java ?

  - by gaqer

  In my Java app, how can I incorporate the browser (which loads and renders URLs) in Swing and access it's DOM and manipulate HTML ? How can you embed such browser in a Rich Internet Application and access it's DOM ? More specifically, Vaadin ? Is there a HTTP proxy class that can load an external URL, and render it to the user ? This was what I was doing on LAMP stack....but I want to switch to Vaadin or some Java web framework where I can just use Java to do everything from server-side to client-side logic design, so I can focus more on application logic. (aka looking for developer friendly frameworks like Vaadin). Thank you and have a great weekend !

• Facebook Like button data for a domain?

  - by mungojerie

  We make a widget for media sites and have included the Facebook Like button, so anyone who installs our widget gets the Like button on every page without having to do additional integration work. We'd like to show the site owner some basic data / analytics about Like activity... which URLs are liked, and how many times. I can't figure out if this is even available via the Graph API or FQL. If it is, I can't tell if I need an app_id and secret token for each domain or not. Any suggestions?

• Good Design for Initialization of Static Array

  - by jplot

  I have a question regarding good design in C++. I have a class A, and all objects of this class use an integer array of constant values (they should share the same array, as their values are constant). The array needs to be computed (just once) before any object A. I thought about having another class B which contains the integer array as a static member, an init() method which would fill this array according to some formula and a static boolean flag initialized (if this variable if true then the init() method would do nothing), but I'm not sure this is the best way to solve my design issue. So my question is, what would be a good design/way to accomplish this ? Thanks in advance.

• Weblogic domain scale up using EM Grid Control 11gR1

  - by dmitry.nefedkin(at)oracle.com

  As you know a weblogic domain consists of set of servers running independently or in a cluster mode, sharing the distributed resources. And in most environments weblogic  cluster consists of multiple managed servers running simultaneously and working together to provide increased scalability and reliability.  These servers can run on the same machine, or be located on different machines.  It's a common task to increase a cluster's capacity by adding new machines to the cluster to host the new server instances.  You can do it by manually installing weblogic binaries to the new host and use pack/unpack commands to add a managed server to this new host.  But with Enterprise Manager Grid Control 11gR1 (EMGC) there is  another way - Fusion Middleware Domain Scale Up  procedure. I'm going to show you how it works.Here is a picture of  my medrec_oradb weblogic domain, what is registered in EMGC. It contains an admin server and a cluster MedRecCluster with  the single managed server MS1. Both admin and managed servers are on the same host oel46-vmware, it's a virtual machine with OEL 4.6 that runs inside our Oracle VM infrastructure.  And here are the application deployments, note that couple of applications are deployed to the cluster.First of all I have to prepare a new machine that will host new managed sever of my cluster. I created new VM with OEL 5.4 using the corresponding Oracle VM template available in Oracle E-Delivery site for Oracle Linux and Oracle VM and named it wls1032. Next step is to install Oracle EM Grid Control 11gR1 Agent to this new host.  You can download it from the OTN page and install it manually,  or you can use Agent Installation Deployment procedure available in EMGC  (Deployments->Agent Installation->Install Agent). Anyway, when you agent is up and running on the new machine, you will see it in EMGC Console in the Targets->Hosts subtab.Now we are ready to scale up our weblogic domain. Click the Deployments tab in Oracle Enterprise Manager Grid Control, and then click Deployment Procedure. Select a Fusion Middleware Domain Scale Up procedure from the list, and click Schedule Deployment. The first page of the FMW Domain Scale Up Wizard is displayed and you can proceed with the deployment process.Select the domain from list, enter the working directory on the admin server host, and also fill the weblogic credentials for the administration server console and the OS credentials for the  admin server host.  Click Next button.  The next step allows you to configure you domain, to add a new manager server to the cluster you should select the cluster in the tree and click Add Server button. Select the newly added server in a tree, choose the target host and  enter the configuration details of your managed server. You can also add new machine and node manager details.  Please note that you cannot change the values in  Domain Location and Fusion Middleware Home fields, so these locations on the target host will be the same as for the admin server host.   Working directory on the target host should have enough free space to store FMW home binaries and domain configuration files.  In my experience the working directories should have at least 3 Gb of free space.  The last thing you should fill is the OS credentials for the target host. The next steps allows you to schedule the execution of the procedure, it is started immediately in my example. The last step is just a review the configuration for the domain scale up. Click Submit to launch the process. You can track the status of the procedure execution by selecting Deployments->Deployment Procedures->Procedure Completion Status in the EMGC Console.As you can see in the picture below, the procedure consists of the many steps, and I'm going to share my experience about the issues that I had at some of the steps. Please keep in mind that you can always continue the execution from the last successfully completed step by clicking Retry button.Check OUI Prerequisites  step may fail if the target host does  not pass prerequisites checks for Weblogic Server installation such as amount of RAM, linux packages installed, etc. Create FMW Clone Archive step may fail if you do not have enough free space in the working directory on the administration server host.Transfer cloning archive to targets  step  may fail if the EMGC agents on the admin server host or on target host are not secured.   You should secure the agent by issuing ./emctl secure agent  command from $AGENT_HOME/bin directory and entering the agent registration password.Both Transfer cloning archive to targets and Apply Clone at target hosts steps may fail if you do not have enough free space in the working directory on the target host. The most complicated issue I had on the Run Inventory Collection  step. The step failed and I noticed that the agent on the target server is also failed with the following error in the $AGENT_HOME/sysman/log/emagent.trc  log file:2010-12-28 11:50:34,310 Thread-2838952848 ERROR upload: Failed to upload file A0000008.xml: Fatal Error.Response received: 500|ORA-20603: The timezone of the multiagent target (/Farm_Localhost_MedRec_medrec_oradb/medrec_oradb,weblogic_domain)is not consistent with the timezone (America/Los_Angeles) reported by other agents.2010-12-28 11:50:34,310 Thread-2838952848 ERROR upload: 1 Failure(s) in a row or XML error for A0000008.xml, retcode = -6, we give up2010-12-28 11:50:35,552 Thread-2838952848 WARN  upload: FxferSend: received fatal error in header from repository: https://oel46-vmware:1159/em/uploadFATAL_ERROR::500|ORA-20603: The timezone of the multiagent target (/Farm_Localhost_MedRec_medrec_oradb/medrec_oradb,weblogic_domain)is not consistent with the timezone (America/Los_Angeles) reported by other agents.2010-12-28 11:50:35,552 Thread-2838952848 ERROR upload: number of fatal error exceeds the limit 32010-12-28 11:50:35,552 Thread-2838952848 ERROR upload: agent will shutdown now2010-12-28 11:50:35,552 Thread-2838952848 ERROR : Signalled to Exit with status 55.

• Glue Records creation

  - by FFrewin

  I need some information on the following issue, as I would like to have it clear on my mind. I have a VPS server. All my sites hosted on this VPS are using as NameServer .gr domain, like ns1.greekdomain.gr & ns2.greekdomain.gr . The .gr domain name is a domain I own with a greek registar. Now, I want to move 2 websites with .co.uk domain names to my VPS. The co.uk domain names are registered with a UK based registar. When I went in the domain management panel, I did changed the nameservers of my domains to my ns.greekdomain.gr ns. However the panel returns an error about invalid nameservers. After digging, I found that my nameservers are not valid because they do not exist as records in the .co.uk registry. And here it starts my big trouble. The .co.uk registart tells me that I have to ask my hosting provider / .gr registar to create a new record to the .uk registry for my nameservers. The .gr registar tells me that my uk registar needs to create a new record for my ns. From Nominet (.co.uk) registry, the one employee tells me that I need to ask my uk registar, the other employee (seemed to not understand what I was asking) told me that they cannot change my nameservers for me, and she told me to contact anyone else (old hosting provider, uk registar, .gr registar) to help me with that. I can't find help from nobody. I try since the last week to transfer my websites to my VPS and I can't. So, the question is who is responsible and who is able to create glue records for my nameservers ?
