  • Oracle WebCenter: Composite Applications & Mash-Ups

    - by kellsey.ruppel(at)oracle.com
    We’ve talked in previous weeks about the key goals of the new release of WebCenter are providing a Modern User Experience, unparalleled Application Integration, converging all the best of the existing portal platforms into WebCenter and delivering a Common User Experience Architecture.  We’ve provided an overview of Oracle WebCenter and discussed some of the other key goals in previous weeks, and this week, we’ll focus on how with the new release of Oracle WebCenter you can create composite applications and mashups.We recently talked with Sachin Agarwal, Director of Product Management of Enterprise 2.0 at Oracle around the topic of Composite Applications and Mashups. Oracle WebCenter provides a rich set of tools and capabilities for pulling in content, applications and collaboration functionality from various different sources and weaving them together into what we call Mashups. Mashups that also consists of transactional applications from multiple sources are specifically called Composite Applications. With the latest release of Oracle WebCenter one can develop highly productive tasked based interfaces that aggregate a related set of applications that are part of a business process and provide in context collaboration tools so that users don’t have to navigate away to different tabs to achieve these tasks. For instance, a call center representative (CSR), not only needs to be able to pull customer information from a CRM application like Siebel, but also related information from Oracle E-Business Suite about whether a specific order has shipped. The CSR will be far more efficient if he or she does not have to open different tabs to login into multiple applications while the customer is waiting, but can access all this information in one mashup.Oracle WebCenter Suite provides a comprehensive set of tooling that enables a business user to quickly aggregate together a mashup and wire-in different backend applications to create a custom dashboard. Not only does Oracle WebCenter supports a wide set of standards (WSRP 1.0, 2.0, JSR 168, JSR 286) that allow portlets  from other applications to be surfaced within WebCenter, but it also provides tools to bring in other web applications such as .Net Applications  as well as SharePoint webparts. The new Business Mash-up editor allows business users to take any Oracle Application or 3rd party application and wire the backend data sources or APIs to a rich set of visualizations and reuse them in mashups.  Moreover, Business users can customize or personalize any page using Oracle WebCenter Composer’s on-the-fly visual page editing features. Users access and select different resource components available in Oracle WebCenter’s Business Dictionary in order to add new content to the page. The Business Dictionary provides a role-based view of available components or resources, and these components can include information from a variety of enterprise resources such as enterprise applications, managed content, rich media, business processes, or business intelligence systems. Together, Oracle WebCenter’s Composer and Business Dictionary give users access to a powerful, yet easy to use, set of tools to personalize and extend their Oracle WebCenter portals and applications without involving IT.Keep checking back this week as we share more information on how you can easily create Commposite Applications and Mashups with Oracle WebCenter .Technorati Tags: UXP, collaboration, enterprise 2.0, modern user experience, oracle, portals, webcenter, applications, mashups, composite applications

  • Network disabled on some wake-ups on saucy laptop

    - by Arild
    Since I upgraded to Saucy Salamander 13.10, with every third suspend or so, the network is disabled and I'm unable to re-enable it. I've had to reboot to make it run again. The network menu will have the option Enable network but clicking it will only produce a tick in the menu item, nothing else changes. How can I make it enable automatically after suspend? In the meantime, is there a workaround to at least manually re-enable it? The PC is a Lenovo IdeaPad S205 using drivers r8169 and rt2800pci.

  • Circular movement - eliminating speed ups near Y = 0

    - by Fibericon
    I have a basic algorithm to rotate an enemy around a 200 unit radius circle with center 0. This is how I'm achieving that: if (position.Y <= 0 && position.X > -200) { position.X -= 2; position.Y = 0 - (float)Math.Sqrt((200 * 200) - (position.X * position.X)); } else { position.X += 2; position.Y = (float)Math.Sqrt((200 * 200) - (position.X * position.X)); } It does work, and I've ensured that at no point does either X or Y equal NaN. However, when Y approaches 0, it seems to go significantly faster. This surprises me, because the Y values are locked to the X, which is being incremented by a steady amount. What can I do to smooth the speed?

  • What is the difference between a PDU and a power strip (both 120V, 15A)?

    - by rob
    I just chatted with an APC rep about upgrading the UPSes at our office. She recommended a single higher-capacity 6-outlet Smart-UPS to replace the four Back-UPS units we currently have. When I asked how she recommended plugging in all the current devices, she recommended using a APC's AP9567 PDU, but said not to use a power strip. At first she said I had to use an APC brand PDU, but after I inquired about using a Tripp-Lite PDU, she said any brand PDU would be fine. The APC PDU previously referenced looks like a standard 120V power strip with overload protection but no surge protection. Other than overload protection (which seems redundant if plugging into the UPS), is there something else I'm missing, or should any power strip (without surge protection) be fine? Edit: I didn't mention it earlier, but we don't have a proper rack--though I did still plan to mount the PDU or power strip to something. I guess I'm wondering if there's any special reason I should pay as much as $180 for the low-end APC PDU (which just looks like a power strip to me) vs. $20-$30 for a workbench power strip.

  • When is my View too smart?

    - by Kyle Burns
    In this posting, I will discuss the motivation behind keeping View code as thin as possible when using patterns such as MVC, MVVM, and MVP.  Once the motivation is identified, I will examine some ways to determine whether a View contains logic that belongs in another part of the application.  While the concepts that I will discuss are applicable to most any pattern which favors a thin View, any concrete examples that I present will center on ASP.NET MVC. Design patterns that include a Model, a View, and other components such as a Controller, ViewModel, or Presenter are not new to application development.  These patterns have, in fact, been around since the early days of building applications with graphical interfaces.  The reason that these patterns emerged is simple – the code running closest to the user tends to be littered with logic and library calls that center around implementation details of showing and manipulating user interface widgets and when this type of code is interspersed with application domain logic it becomes difficult to understand and much more difficult to adequately test.  By removing domain logic from the View, we ensure that the View has a single responsibility of drawing the screen which, in turn, makes our application easier to understand and maintain. I was recently asked to take a look at an ASP.NET MVC View because the developer reviewing it thought that it possibly had too much going on in the view.  I looked at the .CSHTML file and the first thing that occurred to me was that it began with 40 lines of code declaring member variables and performing the necessary calculations to populate these variables, which were later either output directly to the page or used to control some conditional rendering action (such as adding a class name to an HTML element or not rendering another element at all).  This exhibited both of what I consider the primary heuristics (or code smells) indicating that the View is too smart: Member variables – in general, variables in View code are an indication that the Model to which the View is being bound is not sufficient for the needs of the View and that the View has had to augment that Model.  Notable exceptions to this guideline include variables used to hold information specifically related to rendering (such as a dynamically determined CSS class name or the depth within a recursive structure for indentation purposes) and variables which are used to facilitate looping through collections while binding. Arithmetic – as with member variables, the presence of arithmetic operators within View code are an indication that the Model servicing the View is insufficient for its needs.  For example, if the Model represents a line item in a sales order, it might seem perfectly natural to “normalize” the Model by storing the quantity and unit price in the Model and multiply these within the View to show the line total.  While this does seem natural, it introduces a business rule to the View code and makes it impossible to test that the rounding of the result meets the requirement of the business without executing the View.  Within View code, arithmetic should only be used for activities such as incrementing loop counters and calculating element widths. In addition to the two characteristics of a “Smart View” that I’ve discussed already, this View also exhibited another heuristic that commonly indicates to me the need to refactor a View and make it a bit less smart.  That characteristic is the existence of Boolean logic that either does not work directly with properties of the Model or works with too many properties of the Model.  Consider the following code and consider how logic that does not work directly with properties of the Model is just another form of the “member variable” heuristic covered earlier: @if(DateTime.Now.Hour < 12) {     <div>Good Morning!</div> } else {     <div>Greetings</div> } This code performs business logic to determine whether it is morning.  A possible refactoring would be to add an IsMorning property to the Model, but in this particular case there is enough similarity between the branches that the entire branching structure could be collapsed by adding a Greeting property to the Model and using it similarly to the following: <div>@Model.Greeting</div> Now let’s look at some complex logic around multiple Model properties: @if (ModelPageNumber + Model.NumbersToDisplay == Model.PageCount         || (Model.PageCount != Model.CurrentPage             && !Model.DisplayValues.Contains(Model.PageCount))) {     <div>There's more to see!</div> } In this scenario, not only is the View code difficult to read (you shouldn’t have to play “human compiler” to determine the purpose of the code), but it also complex enough to be at risk for logical errors that cannot be detected without executing the View.  Conditional logic that requires more than a single logical operator should be looked at more closely to determine whether the condition should be evaluated elsewhere and exposed as a single property of the Model.  Moving the logic above outside of the View and exposing a new Model property would simplify the View code to: @if(Model.HasMoreToSee) {     <div>There’s more to see!</div> } In this posting I have briefly discussed some of the more prominent heuristics that indicate a need to push code from the View into other pieces of the application.  You should now be able to recognize these symptoms when building or maintaining Views (or the Models that support them) in your applications.

  • What happens in case of utility power failure?

    - by Jake
    (in the office) Today, the UPS battery replace warning light lit up and there was a slight panic as the all the technical people will not be around the next few days. But after thinking a bit further, I realise that in case of power failure, no client computers will be able to turn on in the first place and operations will be disrupted regardless of whether the UPS keeps the server up. This makes me wonder if the UPS is really such a critical component? What do you think?

  • UPS compatible with Linux box?

    - by Somebody still uses you MS-DOS
    I'm buying this unit from deal extreme: it's a bitorrent downloader, with NAS capability. I'm interested in sharing an external HD in it, with media and backup purposes. I'm afraid of energy problems (don't know if this is the correct term), corrupting my mounted drives (like after a storm), so I thought about buying an UPS that sends a "signal" to my Linux box, and a script in my Linux box would unmout everything to avoid problems. Do this "UPS signal" feature exists? Do you have model suggestions? Thanks!

  • How to stop Office 2010 changing " and ' to smart quotes

    - by fatherjack
    I have recently upgraded to Office 2010 at work and there are a few things that are a real problem for me. As a T-SQL developer and SQL Server DBA I copy and paste code to and from various applications and if Word gets involved it can has disastrous consequences. There is an option that appears to be defaulted to "on" that changes a straight quote to what Word describes as a smart quote - see the image below. Note - the single quote suffers from the same effect. Now, getting to the point that...(read more)
