  • User Experience Fundamentals

    - by ultan o'broin
    Understanding what user experience means in the modern work environment is central to building great-looking usable applications on the desktop or mobile devices. What better place to start a series of blog posts on such Applications User Experience team enablement for customers and partners than by sharing what the term really means, writes team member Karen Scipi. Applications UX have gained valuable insights into developing a user experience that reflects the experience of today’s worker. We have observed real workers performing real tasks in real work environments, and we have developed a set of new standards of application design that have been scientifically proven to be beneficial to enable today’s workers. We share such expertise to enable our customers and partners to benefit from our insights and to further their return on investment when building Oracle applications. So, What is User Experience? ?The user interface (UI) is about the on-screen user context provided by the layout of widgets (such as icons, fields, and buttons and more) and the visual impact of colors, typographic choices, and so on. The UI comprises the “look and feel” of the application that users interact with, and reflects, in essence, the most immediate aspects of usability we can now all relate to.  User experience, on the other hand, is about understanding the whole context of the world of work, how workers go about completing tasks, crossing all sorts of boundaries along the way. It is a study of how business processes and workers goals coincide, how users work with technology or other tools to get their jobs done, their interactions with other users, and their response to the technical, physical, and cultural environment around them. User experience is all about how users work—their work environments, office layouts, desk tools, types of devices, their working day, and more. Even their job aids, such as sticky notes, offer insight for UX innovation. User experience matters because businesses needs to be efficient, work must be productive, and users now demand to be satisfied by the applications they work with. In simple terms, tasks finished quickly and accurately for a business evokes organization and worker satisfaction, which in turn makes workers feel good and more than willing to use the application again tomorrow. Design Principles for the Enterprise Worker The consumerization of information technology has raised the bar for enterprise applications. Applications must be consistent, simple, intuitive, but above all contextual, reflecting how and when workers work, in the office or on the go. For example, the Google search experience with its type-ahead keyword-prompting feature is how workers expect to be able to discover enterprise information, too. Type-ahead in PeopleSoft 9.1 To build software that enables workers to be productive, our design principles meet modern work requirements about consistency, with well-organized, context-driven information, geared for a working world of discovery and collaboration. Our applications must also behave in a simple, web-like way just like Amazon, Google, and Apple products that workers use at home or on the go. Our user experience must also reflect workers’ needs for flexibility and well-loved enterprise practices such as using popular desktop tools like Microsoft Excel or Outlook as required. Building User Experience Productively The building blocks of Oracle Fusion Applications are the user experience design patterns. Based on the Oracle Fusion Middleware technology used to build Oracle Fusion Applications, the patterns are reusable solutions to common usability challenges that ADF developers typically face as they build applications, extensions, and integrations. Developers use the patterns as part of their Oracle toolkits to realize great usability consistently and in a productive way. Our design pattern creation process is informed by user experience research and science, an understanding of our technology’s capabilities, the demands for simplification and intuitiveness from users, and the best of Oracle’s acquisitions strategy (an injection of smart people and smart innovation). The patterns are supported by usage guidelines and are tested in our labs and assembled into a library of proven resources we used to build own Oracle Fusion Applications and other Oracle applications user experiences. The design patterns library is now available to the ADF community and to our partners and customers, for free. Developers with ADF skills and other technology skills can now offer more than just coding and functionality and still use the best in enterprise methodologies to ensure that a great user experience is easily applied, scaled, and maintained, whether it be for SaaS or on-premise deployments for Oracle Fusion Applications, for applications coexistence, or for partner integrations scenarios.  Oracle partners and customers already using our design patterns to build solutions and win business in smart and productive ways are now sharing their experiences and insights on pattern use to benefit your entire business. Applications UX is going global with the message and the means. Our hands-on user experience enablement through ADF  is expanding. So, stay tuned to Misha Vaughan's Voice of User Experience (VOX) blog and follow along on Twitter at @usableapps for news of outreach events and other learning opportunities.

  • Tips/Process for web-development using Django in a small team

    - by Mridang Agarwalla
    We're developing a web app uing Django and we're a small team of 3-4 programmers — some doing the UI stuff and some doing the Backend stuff. I'd love some tips and suggestions from the people here. This is out current setup: We're using Git as as our SCM tool and following this branching model. We're following the PEP8 for your style guide. Agile is our software development methodology and we're using Jira for that. We're using the Confluence plugin for Jira for documentation and I'm going to be writing a script that also dumps the PyDocs into Confluence. We're using virtualenv for sandboxing We're using zc.buildout for building This is whatever I can think of off the top of my head. Any other suggestions/tips would be welcome. I feel that we have a pretty good set up but I'm also confident that we could do more. Thanks.

  • What must one know when approaching web development?

    - by Tal Koren
    I just started working as a novice Web Developer. I know PHP pretty well, as well as some basic jQuery. Anyway, my boss told me I should explore and learn about MVC, Memcache, Design Patterns, how Apache servers work and how to set one up etc. What I want to ask is actually this: What should I learn further? Web Development is a big area and most odds are that I'll never stop learning, but what are the basics I should learn about? What are the fundamentals? Currently I'm focusing on Server Side Development, but a very big part of me also wants to become a front-end ninja, so please consider that in your comments. Thanks in advance, you rock. :)

  • OTN Database Developer Day in LA/OC

    - by shay.shmeltzer
    We are taking a little break from the Fusion OTN Developer Days, and instead we'll be taking part in several OTN Developer Days ran by the database team. The aim is to show what Oracle has to offer to various developer groups. As you might guess we specifically are going to be in the Java track. Specifically we are running a lab that will get you to experience Oracle JDeveloper (or OEPE) and will show you how to build an application based on EJB/JSF with Ajax UI. I'm going to be in the upcoming event on May 5th - if you are in the LA area and haven't experienced JDeveloper yet - come in and see what it is all about. Details here.

  • Using the af:poll to refresh parts of the page periodically

    - by shay.shmeltzer
    Just a quick sample of using the af:poll components. A component that enables you to do things in a periodic fashion. For example check if something has changed on the server and update the UI. A more "modern" approach is to actually use push instead of pull, and ADF Faces will allow you to do that with ADS (here, and here). But the poll still has its place. It's quite useful for dashboard type of applications where you want periodic updates of the graphs shown on the page. As you can see it's quite simple to use the tag. I also show my lazy approach to invoking declarative operations on a data control from a backing bean without manually writing code.

  • Native, FOSS GUI prototyping tools?

    - by Oli
    As part of my job as a web developer, I spend an amount of time doing UI prototypes to show the client. It's a pain in the behind but sometimes it has to be done. I've seen Shuttleworth (and the design team) pump out images like this: That's made by something called Balsamiq Mockups... Something that balances on top of Adobe Air (yack!) and costs $79. I've tried it but it kept falling over. I think it had something to do with Air not the app itself. My point is if I'm paying out for something, I want it to be native.

  • design of 'game engine' for small javascript games?

    - by Matt Ball
    I'm making a group of two or three simple javascript games for fun. After someone finishes one game, they'll be presented with a harder or easier version of another game depending on whether the original game was won or lost. I have a high-level question about the design of things: So far I've created a class for one game type that manages the interaction with the UI and the state of the game itself. But for tracking how many of the subgames have been won, or for understanding whether the next game presented should be more or less difficult, are there arguments to be made for making a 'game engine' class? How does the engine communicate to the games? For instance, when a game is won, how is that information relayed to the engine? Is there a better or more common design? (If you want to see what I have so far, the games are slowly taking shape here: https://github.com/yosemitebandit/candela and can be viewed at http://yosemitebandit.com/candela)

  • Can I configure a visual difference view with the notifications provided by TFS?

    - by John Kaster
    I have TFS sending me alerts whenever someone on my team checks in code. (I had to create notification rules for every project, but that's just a sidebar complaint in this question.) These alerts provided some information on who checked in the files when, and what files have changed, with urls to view details in a browser. The thing that baffles me is that I can't just click on the source file and see a visual diff of the changes. There's no link that will auto-launch a diff in Visual Studio (using a custom protocol) from there either. Is there a way to configure TFS to provide a visual diff of the changes to the file that was checked in via this notification UI?

  • ASP.NET WebAPI Security 2: Identity Architecture

    - by Your DisplayName here!
    Pedro has beaten me to the punch with a detailed post (and diagram) about the WebAPI hosting architecture. So go read his post first, then come back so we can have a closer look at what that means for security. The first important takeaway is that WebAPI is hosting independent-  currently it ships with two host integration implementations – one for ASP.NET (aka web host) and WCF (aka self host). Pedro nicely shows the integration into the web host. Self hosting is not done yet so we will mainly focus on the web hosting case and I will point out security related differences when they exist. The interesting part for security (amongst other things of course) is the HttpControllerHandler (see Pedro’s diagram) – this is where the host specific representation of an HTTP request gets converted to the WebAPI abstraction (called HttpRequestMessage). The ConvertRequest method does the following: Create a new HttpRequestMessage. Copy URI, method and headers from the HttpContext. Copies HttpContext.User to the Properties<string, object> dictionary on the HttpRequestMessage. The key used for that can be found on HttpPropertyKeys.UserPrincipalKey (which resolves to “MS_UserPrincipal”). So the consequence is that WebAPI receives whatever IPrincipal has been set by the ASP.NET pipeline (in the web hosting case). Common questions are: Are there situations where is property does not get set? Not in ASP.NET – the DefaultAuthenticationModule in the HTTP pipeline makes sure HttpContext.User (and Thread.CurrentPrincipal – more on that later) are always set. Either to some authenticated user – or to an anonymous principal. This may be different in other hosting environments (again more on that later). Why so generic? Keep in mind that WebAPI is hosting independent and may run on a host that materializes identity completely different compared to ASP.NET (or .NET in general). This gives them a way to evolve the system in the future. How does WebAPI code retrieve the current client identity? HttpRequestMessage has an extension method called GetUserPrincipal() which returns the property as an IPrincipal. A quick look at self hosting shows that the moral equivalent of HttpControllerHandler.ConvertRequest() is HttpSelfHostServer.ProcessRequestContext(). Here the principal property gets only set when the host is configured for Windows authentication (inconsisteny). Do I like that? Well – yes and no. Here are my thoughts: I like that it is very straightforward to let WebAPI inherit the client identity context of the host. This might not always be what you want – think of an ASP.NET app that consists of UI and APIs – the UI might use Forms authentication, the APIs token based authentication. So it would be good if the two parts would live in a separate security world. It makes total sense to have this generic hand off point for identity between the host and WebAPI. It also makes total sense for WebAPI plumbing code (especially handlers) to use the WebAPI specific identity abstraction. But – c’mon we are running on .NET. And the way .NET represents identity is via IPrincipal/IIdentity. That’s what every .NET developer on this planet is used to. So I would like to see a User property of type IPrincipal on ApiController. I don’t like the fact that Thread.CurrentPrincipal is not populated. T.CP is a well established pattern as a one stop shop to retrieve client identity on .NET.  That makes a lot of sense – even if the name is misleading at best. There might be existing library code you want to call from WebAPI that makes use of T.CP (e.g. PrincipalPermission, or a simple .Name or .IsInRole()). Having the client identity as an ambient property is useful for code that does not have access to the current HTTP request (for calling GetUserPrincipal()). I don’t like the fact that that the client identity conversion from host to WebAPI is inconsistent. This makes writing security plumbing code harder. I think the logic should always be: If the host has a client identity representation, copy it. If not, set an anonymous principal on the request message. Btw – please don’t annoy me with the “but T.CP is static, and static is bad for testing” chant. T.CP is a getter/setter and, in fact I find it beneficial to be able to set different security contexts in unit tests before calling in some logic. And, in case you have wondered – T.CP is indeed thread static (and the name comes from a time where a logical operation was bound to a thread – which is not true anymore). But all thread creation APIs in .NET actually copy T.CP to the new thread they create. This is the case since .NET 2.0 and is certainly an improvement compared to how Win32 does things. So to sum it up: The host plumbing copies the host client identity to WebAPI (this is not perfect yet, but will surely be improved). or in other words: The current WebAPI bits don’t ship with any authentication plumbing, but solely use whatever authentication (and thus client identity) is set up by the host. WebAPI developers can retrieve the client identity from the HttpRequestMessage. Hopefully my proposed changes around T.CP and the User property on ApiController will be added. In the next post, I will detail how to add WebAPI specific authentication support, e.g. for Basic Authentication and tokens. This includes integrating the notion of claims based identity. After that we will look at the built-in authorization bits and how to improve them as well. Stay tuned.

  • Is hiding content with JavaScript or "text-indent: -9999px" bad for SEO?

    - by Samuel
    So apparently hiding content using "display: none" is bad for SEO and seen by googlebot as being deceptive. This according to a lot of the posts I read online and questions even on this site. But what if I hide keyword rich text using javascript? A jquery example: $(function() { $('#keywordRichTextContainer').hide(); }); or using visibility hidden: $(function() { $('#keywordRichTextContainer').css({ visibility: 'hidden', position: 'absolute' }); }); Would any of these techniques cause my site to be penalized? If googlebot can't read javascript then if I'm hiding through js it shouldn't know right? What about using "text-indent: -9999px"?

  • Iron Speed Designer Review

    While Visual Studio allows developers to get productive fast by providing great design tools for a UI, it still lacks the ability to do smart layouts, data connections and queries. It is in this area that RAD suite of applications can tremendously boost productivity by abstracting away some of these issues and saving developer time to focus on business intelligence instead of data extraction and presentation. When it comes to RAD application suites for managed web applications, there is non better than Iron Speed Designer. The ease with which you can create a data-centric web application and have different reports of your data within minutes are unparalleled. This review delves into what Iron Speed Designer has to offer as well as some of its limitations. Iron Speed works with .NET 2.0, 3.0, 3.5 and even the latest version .NET 4.0. Read More >

  • Different callbacks for error or error as first argument?

    - by Florian Margaine
    We (and the JS SO chat room) had a talk with @rlemon some days ago about his Little-XHR library about error handling. Basically, we wanted to decide which error handling pattern should be used: xhr.get({ // Some parameters, and then success: function(data) {}, failure: function(data) {} }) Or: xhr.get({ // Some parameters, and then callback: function(err, data) {} }) One is more jQuery-like, while the other is more Node-like. Some say that the first pattern makes you think more about handling error. I think the opposite, since you may forget the other callback function, while the argument is always there on the second pattern. Any opinion/advantage/drawback about both these patterns?

  • Microsoft Codename Houston

    - by kaleidoscope
    On one of the final talks about SQL Azure in Day 3 of PDC09, David Robinson, Senior PM on the Azure team, announced a project codenamed ‘Houston’ which is basically a Silverlight equivalent of SQL Server Management Studio. The concept comes from the SQL Azure being within the cloud, and if the only way to interact with it is by installing SSMS locally then it does not feel like a consistent story. From the limited preview, it only contains the basics but it clearly lets you create tables, stored procedures and views, edit them, even add data to tables in a grid view reminiscent of Microsoft Access. The UI was based around the standard ribbon bar, object window on the left and working pane on the right. As of now this tool is still pre-alpha and it seems like a basic tool that will facilitate rapid database development on cloud. When asked about general availability, no dates were given but calendar 2010 was indicated as the target. More information can be found at:      http://sqlfascination.com/2009/11/20/pdc-09-day-3-sql-azure-and-codename-houston-announcement/   Tinu, O

  • ODI 12c - Loading Files into Oracle, community post from ToadWorld

    - by David Allan
    There's a complete soup to nuts post from Deepak Vohra on the Oracle community pages of ToadWorld on loading a fixed length file into the Oracle database. This post is interesting from a few fronts; firstly this is the out of the box experience, no specialized KMs so just basic integration from getting the software installed to running a mapping. Also it demonstrates fixed length file integration including how to use the ODI UI to define the fields and pertinent properties.  Check the blog post out below.... http://www.toadworld.com/platforms/oracle/w/wiki/10935.loading-text-file-data-into-oracle-database-12c-with-oracle-data-integrator-12c.aspx Hopefully you also find this useful, many thanks to Deepak for sharing his experiences. You could take this example further and illustrate how to load into Oracle using the LKM File to Oracle via External table knowledge module which will perform much better and also leverage such things as using wildcards for loading many files into the 12c database.

  • Version Control without CVS

    - by Lo Wai Lun
    My partners and I have been building an application that requires users to authenticate with password and user ID for member registration and transaction. Very often, tasks for designing UI, Datagrid view event trigger and data access using SQL are allocated to different person. Sometimes, there are different versions to be updated but the database structure used are different If everybody finishes their own part and submit the project on their own onto the shared cloud rivers, there must be a huge cost for software maintenance and re-engineering. How should the task to be submitted so as to minimize the cost for re-engineering without the software like winCVS and Tortoise HG?

  • Switching the layout in Orchard CMS

    - by Bertrand Le Roy
    The UI composition in Orchard is extremely flexible, thanks in no small part to the usage of dynamic Clay shapes. Every notable UI construct in Orchard is built as a shape that other parts of the system can then party on and modify any way they want. Case in point today: modifying the layout (which is a shape) on the fly to provide custom page structures for different parts of the site. This might actually end up being built-in Orchard 1.0 but for the moment it’s not in there. Plus, it’s quite interesting to see how it’s done. We are going to build a little extension that allows for specialized layouts in addition to the default layout.cshtml that Orchard understands out of the box. The extension will add the possibility to add the module name (or, in MVC terms, area name) to the template name, or module and controller names, or module, controller and action names. For example, the home page is served by the HomePage module, so with this extension you’ll be able to add an optional layout-homepage.cshtml file to your theme to specialize the look of the home page while leaving all other pages using the regular layout.cshtml. I decided to implement this sample as a theme with code. This way, the new overrides are only enabled as the theme is activated, which makes a lot of sense as this is going to be where you’ll be creating those additional layouts. The first thing I did was to create my own theme, derived from the default TheThemeMachine with this command: codegen theme CustomLayoutMachine /CreateProject:true /IncludeInSolution:true /BasedOn:TheThemeMachine .csharpcode, .csharpcode pre { font-size: 12px; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Once that was done, I worked around a known bug and moved the new project from the Modules solution folder into Themes (the code was already physically in the right place, this is just about Visual Studio editing). The CreateProject flag in the command-line created a project file for us in the theme’s folder. This is only necessary if you want to run code outside of views from that theme. The code that we want to add is the following LayoutFilter.cs: using System.Linq; using System.Web.Mvc; using System.Web.Routing; using Orchard; using Orchard.Mvc.Filters; namespace CustomLayoutMachine.Filters { public class LayoutFilter : FilterProvider, IResultFilter { private readonly IWorkContextAccessor _wca; public LayoutFilter(IWorkContextAccessor wca) { _wca = wca; } public void OnResultExecuting(ResultExecutingContext filterContext) { var workContext = _wca.GetContext(); var routeValues = filterContext.RouteData.Values; workContext.Layout.Metadata.Alternates.Add( BuildShapeName(routeValues, "area")); workContext.Layout.Metadata.Alternates.Add( BuildShapeName(routeValues, "area", "controller")); workContext.Layout.Metadata.Alternates.Add( BuildShapeName(routeValues, "area", "controller", "action")); } public void OnResultExecuted(ResultExecutedContext filterContext) { } private static string BuildShapeName( RouteValueDictionary values, params string[] names) { return "Layout__" + string.Join("__", names.Select(s => ((string)values[s] ?? "").Replace(".", "_"))); } } } This filter is intercepting ResultExecuting, which is going to provide a context object out of which we can extract the route data. We are also injecting an IWorkContextAccessor dependency that will give us access to the current Layout object, so that we can add alternate shape names to its metadata. We are adding three possible shape names to the default, with different combinations of area, controller and action names. For example, a request to a blog post is going to be routed to the “Orchard.Blogs” module’s “BlogPost” controller’s “Item” action. Our filters will then add the following shape names to the default “Layout”: Layout__Orchard_Blogs Layout__Orchard_Blogs__BlogPost Layout__Orchard_Blogs__BlogPost__Item Those template names get mapped into the following file names by the system (assuming the Razor view engine): Layout-Orchard_Blogs.cshtml Layout-Orchard_Blogs-BlogPost.cshtml Layout-Orchard_Blogs-BlogPost-Item.cshtml This works for any module/controller/action of course, but in the sample I created Layout-HomePage.cshtml (a specific layout for the home page), Layout-Orchard_Blogs.cshtml (a layout for all the blog views) and Layout-Orchard_Blogs-BlogPost-Item.cshtml (a layout that is specific to blog posts). Of course, this is just an example, and this kind of dynamic extension of shapes that you didn’t even create in the first place is highly encouraged in Orchard. You don’t have to do it from a filter, we only did it this way because that was a good place where we could get the context that we needed. And of course, you can base your alternate shape names on something completely different from route values if you want. For example, you might want to create your own part that modifies the layout for a specific content item, or you might want to do it based on the raw URL (like it’s done in widget rules) or who knows what crazy custom rule. The point of all this is to show that extending or modifying shapes is easy, and the layout just happens to be a shape. In other words, you can do whatever you want. Ain’t that nice? The custom theme can be found here: Orchard.Theme.CustomLayoutMachine.1.0.nupkg Many thanks to Louis, who showed me how to do this.
