• What would you recommend for a large-scale Java data grid technology: Terracotta, GigaSpaces, Cohere

  - by cliff.meyers

  I've been reading up on so-called "data grid" solutions for the Java platform including Terracotta, GigaSpaces and Coherence. I was wondering if anyone has real-world experience working any of these tools and could share their experience. I'm also really curious to know what scale of deployment people have worked with: are we talking 2-4 node clusters or have you worked with anything significantly larger than that? I'm attracted to Terracotta because of its "drop in" support for Hibernate and Spring, both of which we use heavily. I also like the idea of how it decorates bytecode based on configuration and doesn't require you to program against a "grid API." I'm not aware of any advantages to tools which use the approach of an explicit API but would love to hear about them if they do in fact exist. :) I've also spent time reading about memcached but am more interested in hearing feedback on these three specific solutions. I would be curious to hear how they measure up against memcached in the event someone has used both.

• Naming selenium grid nodes. Spawning a specific node

  - by ???? ????

  I'm trying to implement a kind of default queues in selenium hub. There is a possibility to specify node's name (actually its environment, smth like "firefox on ubuntu" or "chrome on windows"). Selenium grid itself has a default queue, it works according to 'First In, First Out' principle. But I want to prioritize some of my tasks given to selenium server. I have no possibility to introduce custom queue (seems like there is no API for that), that's why I decided to separate queue's logic from selenium server. I'll only call a specific node with specific name (environment) for example "firefox important node" or smth like that. So, I want to know how to directly tell selenium which node to use for my task? And generally, am I thinking in a right way? Here are my configs: hubConfig.json.erb { "host": null, "port": <%= node[:selenium][:server][:port] %>, "newSessionWaitTimeout": -1, "servlets" : [], "prioritizer": null, "capabilityMatcher": "org.openqa.grid.internal.utils.DefaultCapabilityMatcher", "throwOnCapabilityNotPresent": true, "nodePolling": <%= node[:selenium][:server][:node_polling] %>, "cleanUpCycle": <%= node[:selenium][:server][:cleanup_cycle] %>, "timeout": <%= node[:selenium][:server][:timeout] %>, "browserTimeout": 0, "maxSession": <%= node[:selenium][:server][:max_session] %> } nodeConfig.json.erb { "capabilities": [ { "browserName": "firefox", "maxInstances": 5, "seleniumProtocol": "WebDriver" }, { "browserName": "chrome", "maxInstances": 5, "seleniumProtocol": "WebDriver" }, { "browserName": "phantomjs", "maxInstances": 5, "seleniumProtocol": "WebDriver" } ], "configuration": { "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy", "maxSession": <%= node[:selenium][:node][:max_session] %>, "port": <%= node[:selenium][:node][:port] %>, "host": "<%= node[:fqdn] %>", "register": true, "registerCycle": <%= node[:selenium][:node][:register_cycle] %>, "hubPort": <%= node[:selenium][:server][:port] %> } } And my Driver class: ... def remote_driver @browser = Watir::Browser.new(:remote, :url => "http://myhub.com:4444/wd/hub", :http_client => client, :desired_capabilities => capabilities ) end def capabilities Selenium::WebDriver::Remote::Capabilities.send( "firefox", :javascript_enabled => true, :css_selectors_enabled => true, :takes_screenshot => true ) end def client client = Selenium::WebDriver::Remote::Http::Default.new client.timeout = 360 client end ... I still don't know how to use specified node for my task. If I try to start a driver adding :name => "firefox important node" and extend nodeConfig.json.erb's configuration with environments: - name: "firefox important node" browser: "*firefox" - name: "Firefox36 on Linux" browser: "*firefox" selenium just starts random firefox browser on a random node. How can I control it?

• How do I layout a form in WPF using grid or other controls for maintainability

  - by Jason Coyne

  I have a WPF form, I want to lay out a standard form onto it. Each form element will have a label, and then a control. Pretty standard stuff. If I use a wrap panel, it can cause the label and the control to be separated, but I want them to stay together. is there some WPF equivalent of nobr? Grid works, and allows for column spanning etc, however I really really hate that you specify the column and row on each control. This makes it extremely inconvenient to reorder or insert things into the list. Is there a way to get the grid to use more HTML style column/rows where the items are a child of the row they are in, so that I can re-order easily? Is there some other control that will let me layout a form easily?

• What grid distributed computing frameworks are currently favoured for trading systems

  - by Rich

  There seems to a quite a few grid computing frameworks out there, but which ones are actually being used to any great extent by the investment banks for purposes of low latency distributing calculation? I'd be interested to hear answers covering both windows,Linux and cross platform. Also, what RPC mechanisms seem to be favoured most? I've heard that for reason of low latency and speed, the calculations themselves are quite often written in C++/C as calculations running on VMs are several orders of magnitude slower than native code. Does this seem to be a common scenario in practice? e.g distributed .NET grid framework running calculations written in native c++/c?

• DDD Infrastructure services

  - by Zygimantas

  Hello, I am learning DDD and I am a little bit lost in Infrastructure layer: As I understand, "all good DDD applications" should have 4 layers: Presentation, Application, Domain and Infrastructure. Database should be accessed using Repositories. Repository interfaces should be in Domain layer and repository implementation - in Infrastructure (reference http://stackoverflow.com/questions/693221/ddd-where-to-keep-domain-interfaces-the-infrastructure). Application, Domain and Infrastructure layer should/may have services (reference www.lostechies.com/blogs/jimmy_bogard/archive/2008/08/21/services-in-domain-driven-design.aspx), in example EmailService in Infrastructure layer which sends Email messages. BUT, inside Infrastructure layer we have repository implementations, which are used to access database. So, in this case, repositories are database services? What is the difference between Infrastructure service and repository? Thanks in advance!

• Distributing requests to Selenium Grid RC's?

  - by intervigil

  I've got a situation here where I have a central selenium grid hub, and several RC's running on my gogrid account. When I access it to run tests, it basically queues all the incoming test requests and executes them serially on only one of the RC's, instead of spreading them out to use available RC's. The tests come from multiple projects, so I'm not looking to parallelize the tests themselves, just to split the requests that come from multiple projects across the multiple RC's. From everything I've read, it seems like selenium grid should be doing this already, yet I only see one RC used to run every single test. Is there something I'm missing?

• web grid server pagination trigger multiple controller call when changing page

  - by Thomas Scattolin

  When I server-filter on "au" my web grid and change page, multiple call to the controller are done : the first with 0 filtering, the second with "a" filtering, the third with "au" filtering. My table load huge data so the first call is longer than others. I see the grid displaying firstly the third call result, then the second, and finally the first call (this order correspond to the response time of my controller due to filter parameter) Why are all that controller call made ? Can't just my controller be called once with my total filter "au" ? What should I do ? Here is my grid : $("#" + gridId).kendoGrid({ selectable: "row", pageable: true, filterable:true, scrollable : true, //scrollable: { // virtual: true //false // Bug : Génère un affichage multiple... //}, navigatable: true, groupable: true, sortable: { mode: "multiple", // enables multi-column sorting allowUnsort: true }, dataSource: { type: "json", serverPaging: true, serverSorting: true, serverFiltering: true, serverGrouping:false, // Ne fonctionne pas... pageSize: '@ViewBag.Pagination', transport: { read: { url: Procvalue + "/LOV", type: "POST", dataType: "json", contentType: "application/json; charset=utf-8" }, parameterMap: function (options, type) { // Mise à jour du format d'envoi des paramètres // pour qu'ils puissent être correctement interprétés côté serveur. // Construction du paramètre sort : if (options.sort != null) { var sort = options.sort; var sort2 = ""; for (i = 0; i < sort.length; i++) { sort2 = sort2 + sort[i].field + '-' + sort[i].dir + '~'; } options.sort = sort2; } if (options.group != null) { var group = options.group; var group2 = ""; for (i = 0; i < group.length; i++) { group2 = group2 + group[i].field + '-' + group[i].dir + '~'; } options.group = group2; } if (options.filter != null) { var filter = options.filter.filters; var filter2 = ""; for (i = 0; i < filter.length; i++) { // Vérification si type colonne == string. // Parcours des colonnes pour trouver celle qui a le même nom de champ. var type = ""; for (j = 0 ; j < colonnes.length ; j++) { if (colonnes[j].champ == filter[i].field) { type = colonnes[j].type; break; } } if (filter2.length == 0) { if (type == "string") { // Avec '' autour de la valeur. filter2 = filter2 + filter[i].field + '~' + filter[i].operator + "~'" + filter[i].value + "'"; } else { // Sans '' autour de la valeur. filter2 = filter2 + filter[i].field + '~' + filter[i].operator + "~" + filter[i].value; } } else { if (type == "string") { // Avec '' autour de la valeur. filter2 = filter2 + '~' + options.filter.logic + '~' + filter[i].field + '~' + filter[i].operator + "~'" + filter[i].value + "'"; }else{ filter2 = filter2 + '~' + options.filter.logic + '~' + filter[i].field + '~' + filter[i].operator + "~" + filter[i].value; } } } options.filter = filter2; } var json = JSON.stringify(options); return json; } }, schema: { data: function (data) { return eval(data.data.Data); }, total: function (data) { return eval(data.data.Total); } }, filter: { logic: "or", filters:filtre(valeur) } }, columns: getColonnes(colonnes) }); Here is my controller : [HttpPost] public ActionResult LOV([DataSourceRequest] DataSourceRequest request) { return Json(CProduitsManager.GetProduits().ToDataSourceResult(request)); }

• Algorithm for dragging objects on a fixed grid

  - by FlyingStreudel

  Hello, I am working on a program for the mapping and playing of the popular tabletop game D&D :D Right now I am working on getting the basic functionality like dragging UI elements around, snapping to the grid and checking for collisions. Right now every object when released from the mouse immediately snaps to the nearest grid point. This causes an issue when something like a player object snaps to a grid point that has a wall -or other- adjacent. So essentially when the player is dropped they wind up with some of the wall covering them. This is fine and working as intended, however the problem is that now my collision detection is tripped whenever you try to move this player because its sitting underneath a wall and because of this you cant drag the player anymore. Here is the relevant code: void UIObj_MouseMove(object sender, MouseEventArgs e) { blocked = false; if (dragging) { foreach (UIElement o in ((Floor)Parent).Children) { if (o.GetType() != GetType() && o.GetType().BaseType == typeof(UIObj) && Math.Sqrt(Math.Pow(((UIObj)o).cX - cX, 2) + Math.Pow(((UIObj)o).cY - cY, 2)) < Math.Max(r.Height + ((UIObj)o).r.Height, r.Width + ((UIObj)o).r.Width)) { double Y = e.GetPosition((Floor)Parent).Y; double X = e.GetPosition((Floor)Parent).X; Geometry newRect = new RectangleGeometry(new Rect(Margin.Left + (X - prevX), Margin.Top + (Y - prevY), Margin.Right + (X - prevX), Margin.Bottom + (Y - prevY))); GeometryHitTestParameters ghtp = new GeometryHitTestParameters(newRect); VisualTreeHelper.HitTest(o, null, new HitTestResultCallback(MyHitTestResultCallback), ghtp); } } if (!blocked) { Margin = new Thickness(Margin.Left + (e.GetPosition((Floor)Parent).X - prevX), Margin.Top + (e.GetPosition((Floor)Parent).Y - prevY), Margin.Right + (e.GetPosition((Floor)Parent).X - prevX), Margin.Bottom + (e.GetPosition((Floor)Parent).Y - prevY)); InvalidateVisual(); } prevX = e.GetPosition((Floor)Parent).X; prevY = e.GetPosition((Floor)Parent).Y; cX = Margin.Left + r.Width / 2; cY = Margin.Top + r.Height / 2; } } internal virtual void SnapToGrid() { double xPos = Margin.Left; double yPos = Margin.Top; double xMarg = xPos % ((Floor)Parent).cellDim; double yMarg = yPos % ((Floor)Parent).cellDim; if (xMarg < ((Floor)Parent).cellDim / 2) { if (yMarg < ((Floor)Parent).cellDim / 2) { Margin = new Thickness(xPos - xMarg, yPos - yMarg, xPos - xMarg + r.Width, yPos - yMarg + r.Height); } else { Margin = new Thickness(xPos - xMarg, yPos - yMarg + ((Floor)Parent).cellDim, xPos - xMarg + r.Width, yPos - yMarg + ((Floor)Parent).cellDim + r.Height); } } else { if (yMarg < ((Floor)Parent).cellDim / 2) { Margin = new Thickness(xPos - xMarg + ((Floor)Parent).cellDim, yPos - yMarg, xPos - xMarg + ((Floor)Parent).cellDim + r.Width, yPos - yMarg + r.Height); } else { Margin = new Thickness(xPos - xMarg + ((Floor)Parent).cellDim, yPos - yMarg + ((Floor)Parent).cellDim, xPos - xMarg + ((Floor)Parent).cellDim + r.Width, yPos - yMarg + ((Floor)Parent).cellDim + r.Height); } } } Essentially I am looking for a simple way to modify the existing code to allow the movement of a UI element that has another one sitting on top of it. Thanks!

• Boost your infrastructure with Coherence into the Cloud

  - by Nino Guarnacci

  Authors: Nino Guarnacci & Francesco Scarano,  at this URL could be found the original article:  http://blogs.oracle.com/slc/coherence_into_the_cloud_boost. Thinking about the enterprise cloud, come to mind many possible configurations and new opportunities in enterprise environments. Various customers needs that serve as guides to this new trend are often very different, but almost always united by two main objectives: Elasticity of infrastructure both Hardware and Software Investments related to the progressive needs of the current infrastructure Characteristics of innovation and economy. A concrete use case that I worked on recently demanded the fulfillment of two basic requirements of economy and innovation.The client had the need to manage a variety of data cache, which can process complex queries and parallel computational operations, maintaining the caches in a consistent state on different server instances, on which the application was installed.In addition, the customer was looking for a solution that would allow him to manage the likely situations in load peak during certain times of the year.For this reason, the customer requires a replication site, on which convey part of the requests during periods of peak; the desire was, however, to prevent the immobilization of investments in owned hardware-software architectures; so, to respond to this need, it was requested to seek a solution based on Cloud technologies and architectures already offered by the market. Coherence can already now address the requirements of large cache between different nodes in the cluster, providing further technology to search and parallel computing, with the simultaneous use of all hardware infrastructure resources. Moreover, thanks to the functionality of "Push Replication", which can replicate and update the information contained in the cache, even to a site hosted in the cloud, it is satisfied the need to make resilient infrastructure that can be based also on nodes temporarily housed in the Cloud architectures. There are different types of configurations that can be realized using the functionality "Push-Replication" of Coherence. Configurations can be either: Active - Passive  Hub and Spoke Active - Active Multi Master Centralized Replication Whereas the architecture of this particular project consists of two sites (Site 1 and Site Cloud), between which only Site 1 is enabled to write into the cache, it was decided to adopt an Active-Passive Configuration type (Hub and Spoke). If, however, the requirement should change over time, it will be particularly easy to change this configuration in an Active-Active configuration type. Although very simple, the small sample in this post, inspired by the specific project is effective, to better understand the features and capabilities of Coherence and its configurations. Let's create two distinct coherence cluster, located at miles apart, on two different domain contexts, one of them "hosted" at home (on-premise) and the other one hosted by any cloud provider on the network (or just the same laptop to test it :)). These two clusters, which we call Site 1 and Site Cloud, will contain the necessary information, so a simple client can insert data only into the Site 1. On both sites will be subscribed a listener, who listens to the variations of specific objects within the various caches. To implement these features, you need 4 simple classes: CachedResponse.java Represents the POJO class that will be inserted into the cache, and fulfills the task of containing useful information about the hypothetical links navigation ResponseSimulatorHelper.java Represents a link simulator, which has the task of randomly creating objects of type CachedResponse that will be added into the caches CacheCommands.java Represents the model of our example, because it is responsible for receiving instructions from the controller and performing basic operations against the cache, such as insert, delete, update, listening, objects within the cache Shell.java It is our controller, which give commands to be executed within the cache of the two Sites So, summarily, we execute the java class "Shell", asking it to put into the cache 100 objects of type "CachedResponse" through the java class "CacheCommands", then the simulator "ResponseSimulatorHelper" will randomly create new instances of objects "CachedResponse ". Finally, the Shell class will listen to for events occurring within the cache on the Site Cloud, while insertions and deletions are performed on Site 1. Now, we realize the two configurations of two respective sites / cluster: Site 1 and Site Cloud.For the Site 1 we define a cache of type "distributed" with features of "read and write", using the cache class store for the "push replication", a functionality offered by the project "incubator" of Oracle Coherence.For the "Site Cloud" we expect even the definition of “distributed” cache type with tcp proxy feature enabled, so it can receive updates from Site 1.  Coherence Cache Config XML file for "storage node" on "Site 1" site1-prod-cache-config.xml Coherence Cache Config XML file for "storage node" on "Site Cloud" site2-prod-cache-config.xml For two clients "Shell" which will connect respectively to the two clusters we have provided two easy access configurations.  Coherence Cache Config XML file for Shell on "Site 1" site1-shell-prod-cache-config.xml Coherence Cache Config XML file for Shell on "Site Cloud" site2-shell-prod-cache-config.xml Now, we just have to get everything and run our tests. To start at least one "storage" node (which holds the data) for the "Cloud Site", we can run the standard class  provided OOTB by Oracle Coherence com.tangosol.net.DefaultCacheServer with the following parameters and values:-Xmx128m-Xms64m-Dcom.sun.management.jmxremote -Dtangosol.coherence.management=all -Dtangosol.coherence.management.remote=true -Dtangosol.coherence.distributed.localstorage=true -Dtangosol.coherence.cacheconfig=config/site2-prod-cache-config.xml-Dtangosol.coherence.clusterport=9002-Dtangosol.coherence.site=SiteCloud To start at least one "storage" node (which holds the data) for the "Site 1", we can perform again the standard class provided by Coherence  com.tangosol.net.DefaultCacheServer with the following parameters and values:-Xmx128m-Xms64m-Dcom.sun.management.jmxremote -Dtangosol.coherence.management=all -Dtangosol.coherence.management.remote=true -Dtangosol.coherence.distributed.localstorage=true -Dtangosol.coherence.cacheconfig=config/site1-prod-cache-config.xml-Dtangosol.coherence.clusterport=9001-Dtangosol.coherence.site=Site1 Then, we start the first client "Shell" for the "Cloud Site", launching the java class it.javac.Shell  using these parameters and values: -Xmx64m-Xms64m-Dcom.sun.management.jmxremote -Dtangosol.coherence.management=all -Dtangosol.coherence.management.remote=true -Dtangosol.coherence.distributed.localstorage=false -Dtangosol.coherence.cacheconfig=config/site2-shell-prod-cache-config.xml-Dtangosol.coherence.clusterport=9002-Dtangosol.coherence.site=SiteCloud Finally, we start the second client "Shell" for the "Site 1", re-launching a new instance of class  it.javac.Shell  using  the following parameters and values: -Xmx64m-Xms64m-Dcom.sun.management.jmxremote -Dtangosol.coherence.management=all -Dtangosol.coherence.management.remote=true -Dtangosol.coherence.distributed.localstorage=false -Dtangosol.coherence.cacheconfig=config/site1-shell-prod-cache-config.xml-Dtangosol.coherence.clusterport=9001-Dtangosol.coherence.site=Site1  And now, let’s execute some tests to validate and better understand our configuration. TEST 1The purpose of this test is to load the objects into the "Site 1" cache and seeing how many objects are cached on the "Site Cloud". Within the "Shell" launched with parameters to access the "Site 1", let’s write and run the command: load test/100 Within the "Shell" launched with parameters to access the "Site Cloud" let’s write and run the command: size passive-cache Expected result If all is OK, the first "Shell" has uploaded 100 objects into a cache named "test"; consequently the "push-replication" functionality has updated the "Site Cloud" by sending the 100 objects to the second cluster where they will have been posted into a respective cache, which we named "passive-cache". TEST 2The purpose of this test is to listen to deleting and adding events happening on the "Site 1" and that are replicated within the cache on "Cloud Site". In the "Shell" launched with parameters to access the "Site Cloud" let’s write and run the command: listen passive-cache/name like '%' or a "cohql" query, with your preferred parameters In the "Shell" launched with parameters to access the "Site 1" let’s write and run the following commands: load test/10 load test2/20 delete test/50 Expected result If all is OK, the "Shell" to Site Cloud let us to listen to all the add and delete events within the cache "cache-passive", whose objects satisfy the query condition "name like '%' " (ie, every objects in the cache; you could change the tests and create different queries).Through the Shell to "Site 1" we launched the commands to add and to delete objects on different caches (test and test2). With the "Shell" running on "Site Cloud" we got the evidence (displayed or printed, or in a log file) that its cache has been filled with events and related objects generated by commands executed from the" Shell "on" Site 1 ", thanks to "push-replication" feature.  Other tests can be performed, such as, for example, the subscription to the events on the "Site 1" too, using different "cohql" queries, changing the cache configuration,  to effectively demonstrate both the potentiality and  the versatility produced by these different configurations, even in the cloud, as in our case. More information on how to configure Coherence "Push Replication" can be found in the Oracle Coherence Incubator project documentation at the following link: http://coherence.oracle.com/display/INC10/Home More information on Oracle Coherence "In Memory Data Grid" can be found at the following link: http://www.oracle.com/technetwork/middleware/coherence/overview/index.html To download and execute the whole sources and configurations of the example explained in the above post,  click here to download them; After download the last available version of the Push-Replication Pattern library implementation from the Oracle Coherence Incubator site, and download also the related and required version of Oracle Coherence. For simplicity the required .jarS to execute the example (that can be found into the Push-Replication-Pattern  download and Coherence Distribution download) are: activemq-core-5.3.1.jar activemq-protobuf-1.0.jar aopalliance-1.0.jar coherence-commandpattern-2.8.4.32329.jar coherence-common-2.2.0.32329.jar coherence-eventdistributionpattern-1.2.0.32329.jar coherence-functorpattern-1.5.4.32329.jar coherence-messagingpattern-2.8.4.32329.jar coherence-processingpattern-1.4.4.32329.jar coherence-pushreplicationpattern-4.0.4.32329.jar coherence-rest.jar coherence.jar commons-logging-1.1.jar commons-logging-api-1.1.jar commons-net-2.0.jar geronimo-j2ee-management_1.0_spec-1.0.jar geronimo-jms_1.1_spec-1.1.1.jar http.jar jackson-all-1.8.1.jar je.jar jersey-core-1.8.jar jersey-json-1.8.jar jersey-server-1.8.jar jl1.0.jar kahadb-5.3.1.jar miglayout-3.6.3.jar org.osgi.core-4.1.0.jar spring-beans-2.5.6.jar spring-context-2.5.6.jar spring-core-2.5.6.jar spring-osgi-core-1.2.1.jar spring-osgi-io-1.2.1.jar At this URL could be found the original article: http://blogs.oracle.com/slc/coherence_into_the_cloud_boost Authors: Nino Guarnacci & Francesco Scarano

• Infrastructure to effectively set up experiements and learn from them

  - by David

  Open-org.com is in the early stages of creating our first product, a place on the web, where one can ask lawyers questions at a fraction of their normal costs. An early stage front page can be found here. I got inspired by this video, which is recommended by Jeff Atwood, which talks about getting feedback faster, which is the reason for this question. The problem Needless to say, we want our conversion rates to be as high as possible. Therefore, we want to be able to rapidly set up a new experiment where we change something on the site (like moving an image slightly, rewriting a sentence etc.). We then want to present the modified page to a random subset of the users. After that we will compare the conversion rates of the experiment with another version. I could very well imagine that we want to run 10-100 experiments simultaneously and it would be nice to have features, where experiments that obviously have worse results will be ended before schedule. My question Does infrastructure to support the whole process exist? A short description of our infrastructure... We use EC2 and PHP and have a script to automatically start up new instances with all needed software. Still, starting up a new server for every experiment, seems like a bit of overkill, so I am wondering what other options exist. Btw. If you feel like working for Open-org.com, you can pick a task, and start working, or suggest a new task. All profits are given out to the contributors.

• ActionLink Problem with Client Template Telerik MVC grid

  Hi, i m using Telerik grid to present memos received by user below is the code <%Html.Telerik().Grid<UserManagement.Models.SentMemos>() .Name("ReceivedMemos") .Sortable(sorting => sorting .OrderBy(sortOrder => sortOrder.Add(o => o.MemoDate).Descending())) .DataBinding(dataBinding => dataBinding //Ajax binding .Ajax() //The action method which will return JSON .Select("_AjaxBindingReceivedMemos", "OA" ) ). Columns(colums => { colums.Bound(o => o.MemoID).ClientTemplate(Html.ActionLink("Reply", "ReplyMemo", "OA", new { MemoID = "<#=MemoID#>"}, null).ToString()).Title("Reply").Filterable(false).Sortable(false); colums.Bound(o => o.MemoID).ClientTemplate(Html.ActionLink("Acknowledge", "PreviewMemo", "OA", new { id = "<#=MemoID#>"}, null).ToString()).Title("Acknowledge").Filterable(false).Sortable(false); colums.Bound(o => o.Subject).ClientTemplate(Html.ActionLink("<%#=Subject#>", "PreviewMemo", "OA", new { id = "<#=MemoID#>" }, null).ToString()).Title("Subject"); //colums.Bound(o => Html.ActionLink(o.Subject,"PreviewMemo","OA",new{id=o.MemoID},null).ToString()).Title("Subject"); colums.Bound(o => o.FromEmployeeName); colums.Bound(o => o.MemoDate); }) .Sortable() .Filterable() .RowAction((row) => { row.HtmlAttributes.Add("style", "background:#321211;"); }) .Pageable(pager=>pager.PageSize(6)) .PrefixUrlParameters(false) //.ClientEvents(events => events.OnRowDataBound("onRowDataBound")) .Render(); %> where i m binding third column (Subject) my intention is to make an ActionLink where subject is the display text and i want a dynamic ID coming from <#=MemoID#. memo id is working fine and gives me a link with dynamic Memo IDs. the problem is with the subject i.e ("<#=Subject#") is rendered as it is on the screen without mapping to the actual subject of the memo. i have also tried ("<%#=Subject%") but to no gain. any help is highly appriciated regards

• fast sphere-grid intersection

  - by Mat

  hi! given a 3D grid, a 3d point as sphere center and a radius, i'd like to quickly calculate all cells contained or intersected by the sphere. Currently i take the the (gridaligned) boundingbox of the sphere and calculate the two cells for the min anx max point of this boundingbox. then, for each cell between those two cells, i do a box-sphere intersection test. would be great if there was something more efficient thanks!

• Connection Refused running multiple environments on Selenium Grid 1.04 via Ubuntu 9.04

  - by ReadyWater

  Hello, I'm writing a selenium grid test suite which is going to be run on a series of different machines. I wrote most of it on my macbook but have recently transfered it over to my work machine, which is running ubuntu 9.04. That's actually my first experience with a linux machine, so I may be missing something very simple (I have disabled the firewall though). I haven't been able to get the multienvironment thing working at all, and I've been trying and manual reviewing for a while. Any recommendations and help would be greatly, greatly appreciated! The error I'm getting when I run the test is: [java] FAILED CONFIGURATION: @BeforeMethod startFirstEnvironment("localhost", 4444, "*safari", "http://remoteURL:8080/tutor") [java] java.lang.RuntimeException: Could not start Selenium session: ERROR: Connection refused I thought it might be the mac refusing the connection, but using wireshark I determined that no connection attempt was made on the mac . Here's the code for setting up the session, which is where it seems to be dying @BeforeMethod(groups = {"default", "example"}, alwaysRun = true) @Parameters({"seleniumHost", "seleniumPort", "firstEnvironment", "webSite"}) protected void startFirstEnvironment(String seleniumHost, int seleniumPort, String firstEnvironment, String webSite) throws Exception { try{ startSeleniumSession(seleniumHost, seleniumPort, firstEnvironment, webSite); session().setTimeout(TIMEOUT); } finally { closeSeleniumSession(); } } @BeforeMethod(groups = {"default", "example"}, alwaysRun = true) @Parameters({"seleniumHost", "seleniumPort", "secondEnvironment", "webSite"}) protected void startSecondEnvironment(String seleniumHost, int seleniumPort, String secondEnvironment, String webSite) throws Exception { try{ startSeleniumSession(seleniumHost, seleniumPort, secondEnvironment, webSite); session().setTimeout(TIMEOUT); } finally { closeSeleniumSession(); } } and the accompanying build script used to run the test <target name="runMulti" depends="compile" description="Run Selenium tests in parallel (20 threads)"> <echo>${seleniumHost}</echo> <java classpathref="runtime.classpath" classname="org.testng.TestNG" failonerror="true"> <sysproperty key="java.security.policy" file="${rootdir}/lib/testng.policy"/> <sysproperty key="webSite" value="${webSite}" /> <sysproperty key="seleniumHost" value="${seleniumHost}" /> <sysproperty key="seleniumPort" value="${seleniumPort}" /> <sysproperty key="firstEnvironment" value="${firstEnvironment}" /> <sysproperty key="secondEnvironment" value="${secondEnvironment}" /> <arg value="-d" /> <arg value="${basedir}/target/reports" /> <arg value="-suitename" /> <arg value="Selenium Grid Java Sample Test Suite" /> <arg value="-parallel"/> <arg value="methods"/> <arg value="-threadcount"/> <arg value="15"/> <arg value="testng.xml"/> </java>
