• The right way to start out in game development/design [closed]

  - by Marco Sacristão

  Greetings everyone I'm a 19 year old student looking for some help in the field of game development. This question may or may not seem a bit overused, but the fact is that game development has been my life long dream, and after several hours of search I've realized that I've been going in circles for the past three or four months whilst doing such research on how to really get down and dirty with game development, therefor I decided to ask you guys if you could help me out at all. Let me start off with some information about me and things i've already learned about GameDev which might help you out on helping me out (wordplay!): I'm not an expert programmer, but I do have knowledge on how to program in several languages including C and Java (Currently learning Java in my degree in Computer Engineering), but my methodology might not be most correct in terms of syntax (hence my difficulty in starting out, i'm afraid that the starting point might not be the most correct, and it would deploy a wrongful development methodology that would be to corrected later on, in terms of game development or other projects). I have yet to work in a project as large as a game, never in my learning curve of programming I've done a project to the scale of a video game, only very small software (PHP Front-ends and Back-ends, with some basic JQuery and CSS knowledge). I'm not the biggest mathematician or physicist, but I already know that is not a problem, because there are several game engines already available for use and integration with home-made projects (Box2D, etc). I've also learned about some libraries that could be included in said projects, to ease out some process in game development, like SDL for example. I do not know how sprites, states, particles or any specific game-related techniques work. With that being said, you can see that I have some ideas on game development, but I have absolutely no clue on how to design and produce a game, or even how game-like mechanics work. It does not have to be a complex game just to start out, I'd rather learn the basic of game design (Like 2D drawing, tiling, object collision) and test that out in a language that I feel comfortable in which could be later on migrated to other platforms, as long that what I've learned is the correct way to do things, and not just something that I've learned from some guy on Youtube by replicating that code on the video. I'm sorry if my question is not in the best format possible, but I've got so many questions on my mind that are still un-answered that I don't know were to start! Thank you for reading.

• Welcome to my geeks blog

  - by bconlon

  Hi and welcome! I'm Bazza and this is my geeks blog. I have 20 years Visual Studio mainly C++, MFC,  ATL and now, thankfully, C# and I am embarking on the new world (well new to me) of WPF, so I thought I would try and capture my successful...and not so successful...WPF experiences with the geek world. So where to start? WPF? What I know so far... From wiki..."Windows Presentation Foundation (or WPF) is a graphical subsystem for rendering user interfaces in Windows-based applications." Hmm, great but didn't MFC, ATL (my head hurt with that one), and .Net all have APIs to allow me to code against the Windows Graphical Device Interface (GDI)? "Rather than relying on the older GDI subsystem, WPF utilizes DirectX. WPF attempts to provide a consistent programming model for building applications and provides a separation between the user interface and the business logic." OK, different drawing code, same Windows and weren't we always taught to separate our UI, Business Layer and Data Access Layer? "WPF employs XAML, a derivative of XML, to define and link various UI elements. WPF applications can be deployed as standalone desktop programs, or hosted as an embedded object in a website." Cool, now we're getting somewhere. So when they say separation they really mean separation. The crux of this appears to be that you can have creative people writing the UI and making it attractive and intuitive to use, whist the geeks concentrate on writing the Business and Data Access stuff. XAML (eXtensible Application Markup Language) maps XML elements and attributes directly to Common Language Runtime (CLR) object instances, properties and events. True separation of the View and Model. WPF also provides logical separation of a control from its appearance. In a traditional Windows system, all Controls have a base class containing a Windows handle and each Control knows how to render itself. In WPF, the controls are more like those in a Web Browser using Cascading Style Sheet, they are not wrappers for standard Windows Controls. Instead, they have a default 'template' that defines a visual theme which can easily be replaced by a custom template. But it gets better. WPF concentrates heavily on Data Binding where the client can bind directly to data on the server. I think this concept was first introduced in 'Classic' Visual Basic, where you could bind a list directly to a data from an Access database, and you could do similar in ASP .Net. However, the WPF implementation is far superior than it's predecessors. There are also other technologies that I want to look at like LINQ and the Entity Framework, but that's all for now. #

• Nginx and PHP Fundamentals

  - by Elton Stoneman

  Originally posted on: http://geekswithblogs.net/EltonStoneman/archive/2013/08/01/nginx-and-php-fundamentals.aspxHot on the heels of my .NET caching course, I’ve had my first “fundamentals” course released on Pluralsight: Nginx and PHP Fundamentals. It’s a practical look at two of the biggest technologies on the web – Nginx, which is the fastest growing HTTP server around (currently hosting 100+ million sites), and PHP, which powers more websites than any other server-side framework (currently 240+ million sites). The two technologies work well together, both are open-source and cross-platform and both are lightweight and easy to get started with - you just need to download and unzip the runtimes, and with a text editor you can create and host dynamic websites. I’ve used PHP as a second (sometimes third) language since 2005 when I was brought cold into an established codebase to help improve performance, and Nginx to host tier 2 apps for the last couple of years. As with any training course, you learn new things as you produce it, and it was good to focus on a different stack from my commercial .NET world. In the course I start with a website in two parts – one which is just static content, and one which processes a user registration form using ASP.NET MVC, both running in IIS. Over four modules I migrate the app to Nginx and PHP: Hosting Static Content in Nginx – how to deploy and configure Nginx for a basic website; PHP Part 1: Basic Web Forms – installing PHP and an IDE, and building a simple form with server-side validation; PHP Part 2: Packages and Integration – using PECL and Composer for packages to connect to Azure, AWS, Mongo and reCAPTCHA; Hosting PHP in Nginx – configuring Nginx to host our PHP site. Along the way I run some performance stats with JMeter, and the headlines are that Nginx running on Linux outperforms IIS on Windows for static content,by 800 requests per second over 1000 concurrent requests; and Linux+Ngnix+PHP outperforms Windows+IIS+ASP.NET MVC by 700 request per second with the same load. Of course, the headline stats don’t tell the whole story, and when you add OpCode caching for PHP and the ASP.NET Output Cache, the results are very different. As Web architecture moves away from heavy server-side processing, to Single Page Apps with client-side frameworks like AngularJS and Knockout, I think there’s an increasing need for high-performance, low-cost server technologies, and the combination of Nginx and PHP makes a compelling case.

• Craftsmanship Tour: Day 3 &amp; 4 8th Light

  - by Liam McLennan

  Thursday morning the Illinois public transport system came through for me again. I took the Metra train north from Union Station (which was seething with inbound commuters) to Prairie Crossing (Libertyville). At Prairie Crossing I met Paul and Justin from 8th Light and then Justin drove us to the office. The 8th Light office is in an small business park, in a semi-rural area, surrounded by ponds. Upstairs there are two spacious, open areas for developers. At one end of the floor is Doug Bradbury’s walk-and-code station; a treadmill with a desk and computer so that a developer can get exercise at work. At the other end of the floor is a hammock. This irregular office furniture is indicative of the 8th Light philosophy, to pursue excellence without being limited by conventional wisdom. 8th Light have a wall covered in posters, each illustrating one person’s software craftsmanship journey. The posters are a fascinating visualisation of the similarities and differences between each of our progressions. The first thing I did Thursday morning was to create my own poster and add it to the wall. Over two days at 8th Light I did some pairing with the 8th Lighters and we shared thoughts on software development. I am not accustomed to such a progressive and enlightened environment and I found the experience inspirational. At 8th Light TDD, clean code, pairing and kaizen are deeply ingrained in the culture. Friday, during lunch, 8th Light hosted a ‘lunch and learn’ event. Paul Pagel lead us through a coding exercise using micro-pomodori. We worked in pairs, focusing on the pedagogy of pair programming and TDD. After lunch I recorded this interview with Paul Pagel and Justin Martin. We discussed 8th light, craftsmanship, apprenticeships and the limelight framework. Interview with Paul Pagel and Justin Martin My time at Didit, Obtiva and 8th Light has convinced me that I need to give up some of my independence and go back to working in a team. Craftsmen advance their skills by learning from each other, and I can’t do that working at home by myself. The challenge is finding the right team, and becoming a part of it.

• Illegal characters for SharePoint 2010 Content Type name

  - by Kelly Jones

  Quick tip: you can’t include a backslash in the name of the SharePoint 2010 Content Type.  In fact, there are several illegal characters:  \  / : * ? " # % < > { } | ~ & , two consecutive periods (..), or special characters such as a tab. What, you didn’t know that after entering one of these characters in the name?  Is it because you saw this screen: Oh, that’s right….you need to turn off custom errors in the layouts folder…See this blog post for details and you’ll also need to turn off for the web application. Once you do that, you’ll see this: I wonder why the SharePoint team just doesn’t let the user know that the content type name contains illegal characters before the user hits the create button. Here’s a copy of the complete error (for the search engines): Server Error in '/' Application. -------------------------------------------------------------------------------- The content type name 'asdfadsf\asdfasf' cannot contain: \  / : * ?

• Preview of MSDN Library Changes

  - by ScottGu

  The MSDN team has been working some potential changes to the online MSDN Library designed to help streamline the navigation experience and make it easier to find the .NET Framework information you need. To solicit feedback on the proposed changes while they are still in development, they’ve posted a preview version of some proposed changes to a new MSDN Library Preview site which you can check out.  They’ve also created a survey that leads you through the ideas and asks for your opinions on some of the changes.  We’d very much like to have as many people as possible people take the survey and give us feedback. Quick Preview of Some of the Changes Below are some examples of a few of the changes being proposed: Streamlined .NET Namespaces Navigation The current MSDN Class Library lists all .NET namespaces in a flat-namespace (sorted alphabetically): Two downsides of the above approach are: Some of the least-used namespaces are listed first (like Microsoft.Aspnet.Snapin and Microsoft.Build.BuildEngine) All sub-namespaces are listed, which makes the list a little overwhelming, and page-load times to be slow The new MSDN Library Preview Site now lists “System” namespaces first (since those are the most used), and the home-page lists just top-level namespace groups – which makes it easier to find things, and enables the page to load faster:   Class overview and members pages merged into a single topic about each class Previously you had to navigate to several different pages to find member information about types: Links to these are still available in the MSDN Library Preview Site TOC – but the members are also now listed on the overview page, which makes it easy to quickly find everything in one place: Commonly used things are nearer the top of the page One of the other usability improvements with the new MSDN Library Preview Site is that common elements like “Code Examples” and “Inheritance Hierarchy” (for classes) are now listed near the top of the help page – making them easy to quickly find: Give Us Feedback with a Survey Above are just a few of the changes made with the new MSDN preview site – there are many other changes also rolled into it.  The MSDN team is doing usability studies on the new layout and navigation right now, and would very much like feedback on it. If you have 15 minutes and want to help vote on which of these ideas makes it into the production MSDN site, please visit this survey before June 30, play with the changes a bit, and let the MSDN team know what you think. Important Note: the MSDN preview site is not a fully functional version of MSDN – it’s really only there to preview the new ideas themselves, so please don’t expect it to be integrated with the rest of MSDN, with search, etc.  Once the MSDN team gets feedback on some of the changes being proposed they will roll them into the live site for everyone to use. Hope this helps, Scott

• ASP.NET Asynchronous Pages and when to use them

  - by rajbk

  There have been several articles posted about using  asynchronous pages in ASP.NET but none of them go into detail as to when you should use them. I finally found a great post by Thomas Marquardt that explains the process in depth. He addresses a key misconception also: So, in your ASP.NET application, when should you perform work asynchronously instead of synchronously? Well, only 1 thread per CPU can execute at a time.  Did you catch that?  A lot of people seem to miss this point...only one thread executes at a time on a CPU. When you have more than this, you pay an expensive penalty--a context switch. However, if a thread is blocked waiting on work...then it makes sense to switch to another thread, one that can execute now.  It also makes sense to switch threads if you want work to be done in parallel as opposed to in series, but up until a certain point it actually makes much more sense to execute work in series, again, because of the expensive context switch. Pop quiz: If you have a thread that is doing a lot of computational work and using the CPU heavily, and this takes a while, should you switch to another thread? No! The current thread is efficiently using the CPU, so switching will only incur the cost of a context switch. Ok, well, what if you have a thread that makes an HTTP or SOAP request to another server and takes a long time, should you switch threads? Yes! You can perform the HTTP or SOAP request asynchronously, so that once the "send" has occurred, you can unwind the current thread and not use any threads until there is an I/O completion for the "receive". Between the "send" and the "receive", the remote server is busy, so locally you don't need to be blocking on a thread, but instead make use of the asynchronous APIs provided in .NET Framework so that you can unwind and be notified upon completion. Again, it only makes sense to switch threads if the benefit from doing so out weights the cost of the switch. Read more about it in these posts: Performing Asynchronous Work, or Tasks, in ASP.NET Applications http://blogs.msdn.com/tmarq/archive/2010/04/14/performing-asynchronous-work-or-tasks-in-asp-net-applications.aspx ASP.NET Thread Usage on IIS 7.0 and 6.0 http://blogs.msdn.com/tmarq/archive/2007/07/21/asp-net-thread-usage-on-iis-7-0-and-6-0.aspx   PS: I generally do not write posts that simply link to other posts but think it is warranted in this case.

• Vodacom Call Center Management on the NetBeans Platform

  - by Geertjan

  If you live in South Africa, you know about Vodacom. Vodacom is one of the dominant mobile communication companies in South Africa, and beyond, providing voice, messaging, data, and similar mobile services. Inside Vodacom there's an application named Helios, which is a call centre application that had its inception in 2009 and consists of two parts. Firstly, a web-based front-end that allows a call centre agent to service subscribers using a Google-like search on a knowledge base structured as a collection of FAQs. The web-based front-end uses plain-old HTML + CSS + a good helping of JQuery and JQueryUI. This is delivered via JSR-168 portlets running on a cluster of IBM Portal 6 servers. In turn, the portlets communicate via RMI with several back-end EJB's containing the business logic. These EJB's are deployed on a cluster of Weblogic Application Servers, version 10.3.6. The second part is a NetBeans Platform application used for maintaining and constructing the knowledge base, i.e., the back-end of the web-based front-end. Helios is also used for a number of other maintenance functions, such as access permissions, user maintenance, and news bulletins. Below, in the web-based front-end, call centre agents can enter search terms and are presented with a number of FAQs from the knowledge base. Upon selecting a FAQ article, the agent is presented with the article text, the process to guide the subscriber, system checks that display information specific to the subscriber, and links to related applications and articles: Below, you can see that applications are searchable and can be accessed using the same web-based front-end as shown above. And, as can be seen below, knowledge base FAQs are maintained using the Helios Maintenance Application, which is the Vodacom application built on the NetBeans Platform: Several thousand call centre agent user accounts are administered using the Helios Maintenance Application. Below the main FAQ page is shown, together with the About dialog: Vodacom is happy with the back-end NetBeans Platform application. However, the front-end stack runs on quite old technology. Ideally Vodacom would like to migrate the portlets to Oracle Weblogic Portal or Oracle WebCenter, but this hasn't been accomplished yet. Migrating makes sense as the rest of the application server environment consists entirely of Oracle products.

• Tom Cruise: Meet Fusion Apps UX and Feel the Speed

  - by ultan o'broin

  Unfortunately, I am old enough to remember, and now to admit that I really loved, the movie Top Gun. You know the one - Tom Cruise, US Navy F-14 ace pilot, Mr Maverick, crisis of confidence, meets woman, etc., etc. Anyway, one of more memorable lines (there were a few) was: "I feel the need, the need for speed." I was reminded of Tom Cruise recently. Paraphrasing a certain Senior Vice President talking about Oracle Fusion Applications and user experience at an all-hands meeting, I heard that: Applications can never be too easy to use. Performance can never be too fast. Developers, assume that your code is always "on". Perfect. You cannot overstate the user experience importance of application speed to users, or at least their perception of speed. We all want that super speed of execution and performance, and increasingly so as enterprise users bring the expectations of consumer IT into the work environment. Sten Vesterli (@stenvesterli), an Oracle Fusion Applications User Experience Advocate, also addressed the speed point artfully at an Oracle Usability Advisory Board meeting in Geneva. Sten asked us that when we next Googled something, to think about the message we see that Google has found hundreds of thousands or millions of results for us in a split second (for example, About 8,340,000 results (0.23 seconds)). Now, how many results can we see and how many can we use immediately? Yet, this simple message communicating the total results available to us works a special magic about speed, delight, and excitement that Google has made its own in the search space. And, guess what? The Oracle Application Development Framework table component relies on a similar "virtual performance boost", says Sten, when it displays the first 50 records in a table, and uses a scrollbar indicating the total size of the data record set. The user scrolls and the application automatically retrieves more records as needed. Application speed and its perception by users is worth bearing in mind the next time you're at a customer site and the IT Department demands that you retrieve every record from the database. Just think of... Dave Ensor: I'll give you all the rows you ask for in one second. If you promise to use them. (Again, hat tip to Sten.) And then maybe think of... Tom Cruise. And if you want to read about the speed of Oracle Fusion Applications, and what that really means in terms of user productivity for your entire business, then check out the Oracle Applications User Experience Oracle Fusion Applications white papers on the usable apps website.

• Adding AjaxOnly Filter in ASP.NET Web API

  - by imran_ku07

          Introduction:                     Currently, ASP.NET MVC 4, ASP.NET Web API and ASP.NET Single Page Application are the hottest topics in ASP.NET community. Specifically, lot of developers loving the inclusion of ASP.NET Web API in ASP.NET MVC. ASP.NET Web API makes it very simple to build HTTP RESTful services, which can be easily consumed from desktop/mobile browsers, silverlight/flash applications and many different types of clients. Client side Ajax may be a very important consumer for various service providers. Sometimes, some HTTP service providers may need some(or all) of thier services can only be accessed from Ajax. In this article, I will show you how to implement AjaxOnly filter in ASP.NET Web API application.         Description:                     First of all you need to create a new ASP.NET MVC 4(Web API) application. Then, create a new AjaxOnly.cs file and add the following lines in this file, public class AjaxOnlyAttribute : System.Web.Http.Filters.ActionFilterAttribute { public override void OnActionExecuting(System.Web.Http.Controllers.HttpActionContext actionContext) { var request = actionContext.Request; var headers = request.Headers; if (!headers.Contains("X-Requested-With") || headers.GetValues("X-Requested-With").FirstOrDefault() != "XMLHttpRequest") actionContext.Response = request.CreateResponse(HttpStatusCode.NotFound); } }                     This is an action filter which simply checks X-Requested-With header in request with value XMLHttpRequest. If X-Requested-With header is not presant in request or this header value is not XMLHttpRequest then the filter will return 404(NotFound) response to the client.                      Now just register this filter, [AjaxOnly] public string GET(string input)                     You can also register this filter globally, if your Web API application is only targeted for Ajax consumer.         Summary:                       ASP.NET WEB API provide a framework for building RESTful services. Sometimes, you may need your certain API services can only be accessed from Ajax. In this article, I showed you how to add AjaxOnly action filter in ASP.NET Web API. Hopefully you will enjoy this article too.

• DevConnections jQuery Session Slides and Samples posted

  - by Rick Strahl

  I’ve posted all of my slides and samples from the DevConnections VS 2010 Launch event last week in Vegas. All three sessions are contained in a single zip file which contains all slide decks and samples in one place: www.west-wind.com/files/conferences/jquery.zip There were 3 separate sessions: Using jQuery with ASP.NET Starting with an overview of jQuery client features via many short and fun examples, you'll find out about core features like the power of selectors to select document elements, manipulate these elements with jQuery's wrapped set methods in a browser independent way, how to hook up and handle events easily and generally apply concepts of unobtrusive JavaScript principles to client scripting. The session also covers AJAX interaction between jQuery and the .NET server side code using several different approaches including sending HTML and JSON data and how to avoid user interface duplication by using client side templating. This session relies heavily on live examples and walk-throughs. jQuery Extensibility and Integration with ASP.NET Server Controls One of the great strengths of the jQuery Javascript framework is its simple, yet powerful extensibility model that has resulted in an explosion of plug-ins available for jQuery. You need it - chances are there's a plug-in for it! In this session we'll look at a few plug-ins to demonstrate the power of the jQuery plug-in model before diving in and creating our own custom jQuery plug-ins. We'll look at how to create a plug-in from scratch as well as discussing when it makes sense to do so. Once you have a plug-in it can also be useful to integrate it more seamlessly with ASP.NET by creating server controls that coordinate both server side and jQuery client side behavior. I'll demonstrate a host of custom components that utilize a combination of client side jQuery functionality and server side ASP.NET server controls that provide smooth integration in the user interface development process. This topic focuses on component development both for pure client side plug-ins and mixed mode controls. jQuery Tips and Tricks This session was kind of a last minute substitution for an ASP.NET AJAX talk. Nothing too radical here :-), but I focused on things that have been most productive for myself. Look at the slide deck for individual points and some of the specific samples.   It was interesting to see that unlike in previous conferences this time around all the session were fairly packed – interest in jQuery is definitely getting more pronounced especially with microsoft’s recent announcement of focusing on jQuery integration rather than continuing on the path of ASP.NET AJAX – which is a welcome change. Most of the samples also use the West Wind Web & Ajax Toolkit and the support tools contained within it – a snapshot version of the toolkit is included in the samples download. Specicifically a number of the samples use functionality in the ww.jquery.js support file which contains a fairly large set of plug-ins and helper functionality – most of these pieces while contained in the single file are self-contained and can be lifted out of this file (several people asked). Hopefully you'll find something useful in these slides and samples.© Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET  jQuery

• Adding an expression based image in a client report definition file (RDLC)

  - by rajbk

  In previous posts, I showed you how to create a report using Visual Studio 2010 and how to add a hyperlink to the report.  In this post, I show you how to add an expression based image to each row of the report. This similar to displaying a checkbox column for Boolean values.  A sample project is attached to the bottom of this post. To start off, download the project we created earlier from here.  The report we created had a “Discontinued” column of type Boolean. We are going to change it to display an “available” icon or “unavailable” icon based on the “Discontinued” row value.    Load the project and double click on Products.rdlc. With the report design surface active, you will see the “Report Data” tool window. Right click on the Images folder and select “Add Image..”   Add the available_icon.png and discontinued_icon.png images (the sample project at the end of this post has the icon png files)    You can see the images we added in the “Report Data” tool window.   Drag and drop the available_icon into the “Discontinued” column row (not the header) We get a dialog box which allows us to set the image properties. We will add an expression that specifies the image to display based the “Discontinued” value from the Product table. Click on the expression (fx) button.   Add the following expression : = IIf(Fields!Discontinued.Value = True, “discontinued_icon”, “available_icon”)   Save and exit all dialog boxes. In the report design surface, resize the column header and change the text from “Discontinued” to “In Production”.   (Optional) Right click on the image cell (not header) , go to “Image Properties..” and offset it by 5pt from the left. (Optional) Change the border color since it is not set by default for image columns. We are done adding our image column! Compile the application and run it. You will see that the “In Production” column has red ‘x’ icons for discontinued products.

• Creating a bare bone web-browser: After the html parser, javascript parser, etc have done their work, how do I display the content of the webpage?

  - by aste123

  This is a personal project to learn computer programming. I took a look at this: https://www.udacity.com/course/viewer#!/c-cs262 The following is the approach taken in it: Abstract Syntax Tree is created. But javascript is still not completely broken down in order not to confuse with the html tags. Then the javascript interpreter is called on it. Javascript interpreter stores the text from the write() and document.write() to be used later. Then a graphics library in Python is called which will convert everything to a pdf file and then we convert it into png or jpeg and then display it. My Question: I want to display the actual text in a window (which I will design later) like firefox or chrome does instead of image files so that the data can be selected, copied, etc by the user of the browser. How do I accomplish this? In other words, what are the other elements of a bare bone web browser that I am missing? I would prefer to implement most of the stuff in C++ although if things seem too complicated I might go with Python to save time and create a prototype and later creating another bare bone browser in C++ and add more features. This is a project to learn more. I do realize we already have lots of reliable browsers like firefox, etc. The way I feel it is done: I think after all the broken down contents have been created by the parsers and interpreters, I will need to access them individually from within the window's code (like qt) and then decide upon a good way to display them. I am not sure if it is the way this should be done. Additions after useful comment by Kilian Foth: I found this page: http://friendlybit.com/css/rendering-a-web-page-step-by-step/ 14. A DOM tree is built out of the broken HTML 15. New requests are made to the server for each new resource that is found in the HTML source (typically images, style sheets, and JavaScript files). Go back to step 3 and repeat for each resource. 16. Stylesheets are parsed, and the rendering information in each gets attached to the matching node in the DOM tree 17. Javascript is parsed and executed, and DOM nodes are moved and style information is updated accordingly 18. The browser renders the page on the screen according to the DOM tree and the style information for each node 19. You see the page on the screen I need help with step 18. How do I do that? How much work do Webkit and Gecko do? I want to use a readymade layout renderer for step number 18 and not for anything that comes before that.

• Announcing Oracle Enterprise Content Management Suite 11g

  - by [email protected]

  Today Oracle announced Oracle Enterprise Content Management Suite 11g. This is a major release for us, and reinforces our three key themes at Oracle: Complete New in this release - Oracle ECM Suite 11g is built on a single, unified repository. Every piece of content - documents, HTML pages, digital assets, scanned images - is stored and accessbile directly from the repository, whether you are working on websites, creating brand logos, processing accounts payable invoices, or running records and retention functions. It makes complete, end-to-end management of content possible, from the point it enters the organization, through its entire lifecycle. Also new in this release, the installation, access, monitoring and administration of Oracle ECM Suite 11g is centralized. As a complete system, organizations can lower the costs of training and usage by having a centralized source of information that is easily administered. As part of this new unified repository release, Oracle has released a benchmarking white paper that shows the extreme performance and scalability of Oracle ECM Suite. When tested on a two node UCM Server running on Sun Oracle DB Machine Half Rack Hardware with an Exadata storage server, Oracle ECM Suite 11g is able to ingest over 178 million documents per day. Open Oracle ECM Suite 11g is built on a service-oriented architecture. All functions are available through standards-based services calls in Web Services or Java. In this release Oracle unveils Open Web Content Management. Open Web Content Management is a revolutionary approach to web content management that decouples the content management process from the process of creating web applications. One piece of this approach is our one-click web content management. With one click, a web application builder can drag content services into their application, enabling their users to also edit content with just one click. Open Web Content Management is also open because it enables Web developers to add Web content management to new and existing JavaServer Pages (JSP), JavaServer Faces (JSF) and Oracle Application Development Framework (ADF) Faces applications Open content distribution - Oracle ECM Suite 11g offers flexible deployment options with a built-in smart cache so organizations can deliver Web sites or Web applications without requiring Oracle ECM Suite as part of the delivery system Integrated Oracle ECM Suite 11g also offers a series of next generation desktop integrations, providing integrations such as: New MS Office integration with menus to access managed content, insert managed links, and compare managed documents using standard MS Office reviewing tools Automatic identity tagging of documents on download - to help users understand which versions they are viewing and prevent duplicate content items in the content repository. New "smart productivity folders" to show a users workflow inbox, saved searches and checked out content directly from Windows Explorer Drag and drop metadata pop-ups Check in and check out for all file formats with any standard WebDAV server As part of Oracle's Enterprise Application Documents initiative, Oracle Content Management 11g also provides certified application integrations with solution templates You can read the press release here. You can see more assets at the launch center here. You can sign up for the announcement webinar and hear more about the new features here. You can read the benchmarking study here.

• MVC Architecture

  Model-View-Controller (MVC) is an architectural design pattern first written about and implemented by  in 1978. Trygve developed this pattern during the year he spent working with Xerox PARC on a small talk application. According to Trygve, “The essential purpose of MVC is to bridge the gap between the human user's mental model and the digital model that exists in the computer. The ideal MVC solution supports the user illusion of seeing and manipulating the domain information directly. The structure is useful if the user needs to see the same model element simultaneously in different contexts and/or from different viewpoints.”  Trygve Reenskaug on MVC The MVC pattern is composed of 3 core components. Model View Controller The Model component referenced in the MVC pattern pertains to the encapsulation of core application data and functionality. The primary goal of the model is to maintain its independence from the View and Controller components which together form the user interface of the application. The View component retrieves data from the Model and displays it to the user. The View component represents the output of the application to the user. Traditionally the View has read-only access to the Model component because it should not change the Model’s data. The Controller component receives and translates input to requests on the Model or View components. The Controller is responsible for requesting methods on the model that can change the state of the model. The primary benefit to using MVC as an architectural pattern in a project compared to other patterns is flexibility. The flexibility of MVC is due to the distinct separation of concerns it establishes with three distinct components.  Because of the distinct separation between the components interaction is limited through the use of interfaces instead of classes. This allows each of the components to be hot swappable when the needs of the application change or needs of availability change. MVC can easily be applied to C# and the .Net Framework. In fact, Microsoft created a MVC project template that will allow new project of this type to be created with the standard MVC structure in place before any coding begins. The project also creates folders for the three key components along with default Model, View and Controller classed added to the project. Personally I think that MVC is a great pattern in regards to dealing with web applications because they could be viewed from a myriad of devices. Examples of devices include: standard web browsers, text only web browsers, mobile phones, smart phones, IPads, IPhones just to get started. Due to the potentially increasing accessibility needs and the ability for components to be hot swappable is a perfect fit because the core functionality of the application can be retained and the View component can be altered based on the client’s environment and the View component could be swapped out based on the calling device so that the display is targeted to that specific device.

• Silverlight Death Trolls Dancing on XAML&rsquo;s Grave

  - by D'Arcy Lussier

  I’m starting to see a whole bunch of tweets and blog posts on how Silverlight/WPF is dead, or how the XAML team has been disbanded at Microsoft, or how someone predicted Silverlight would die, blah blah blah. They all have a similar ring to it though: “Told ya so!” “They were stupid ideas anyway!” “Serves Microsoft right, boy are they dumb!” Let me tell you something, all those that are gleefully raving about Silverlight/WPF’s demise are nothing more than death trolls. Let’s assume that everything out there is true. Microsoft is obviously moving towards HTML 5 in a huge way (TechCrunch pointed out that SkyDrive has replaced its Silverlight based version with an HTML 5 one), and not just on the web as we’ve seen with recent announcements about how HTML 5 apps will be natively supported on Windows 8. WPF never caught on in the marketplace, regardless of its superior technology offering to Winforms. And Silverlight…well, it gave Flash a good run for its money, but plug-in based web applications are becoming passé in light of HTML 5. (It’s interesting that at a developer conference I put on just a few weeks ago, only 1 out of 60+ sessions included Silverlight. 5 focussed on HTML 5.) So what does this *death* of Silverlight/WPF/XAML mean then in the grand scheme of things (again, assuming that they truly *are* dying/dead)? Well, nothing really…at least nothing bad. Silverlight has given us some fantastic applications and experiences (Vancouver Olympics anyone?), and WP7 couldn’t have launched without Silverlight as its development platform. And WPF, although it had putrid adoption, has had some great success stories. A Canadian company that I talked to recently showed me how they re-wrote their point-of-sale application entirely in WPF, and the product is a huge success providing features their competitors aren’t. Arguably (and I say that only because I know I’m going to get WTF comments for this), VS.NET 2010 is a great example of what a WPF app can provide over previous C++ based applications. Technologies evolve. In a decade we’ve had 5 versions of the .NET framework, seen languages like J# come and go, seen F# appear, see communications layers change with WCF, seen EF go through multiple evolutions and traditional ADO.NET Datasets go extinct (from actual use anyway), and ASP.NET Webforms be replaced with ASP.NET MVC as a preferred web platform. Is Silverlight and WPF done? Maybe…probably?…thing is, it doesn’t really affect me personally in any way, or you…so why would we care if its gets replaced with something better and more robust that we can build better solutions with? Just remember the golden rule: don’t feed the trolls.

• MVC's Html.DropDownList and "There is no ViewData item of type 'IEnumerable<SelectListItem>' that has the key '...'

  - by pjohnson

  ASP.NET MVC's HtmlHelper extension methods take out a lot of the HTML-by-hand drudgery to which MVC re-introduced us former WebForms programmers. Another thing to which MVC re-introduced us is poor documentation, after the excellent documentation for most of the rest of ASP.NET and the .NET Framework which I now realize I'd taken for granted. I'd come to regard using HtmlHelper methods instead of writing HTML by hand as a best practice. When I upgraded a project from MVC 3 to MVC 4, several hidden fields with boolean values broke, because MVC 3 called ToString() on those values implicitly, and MVC 4 threw an exception until you called ToString() explicitly. Fields that used HtmlHelper weren't affected. I then went through dozens of views and manually replaced hidden inputs that had been coded by hand with Html.Hidden calls. So for a dropdown list I was rendering on the initial page as empty, then populating via JavaScript after an AJAX call, I tried to use a HtmlHelper method: @Html.DropDownList("myDropdown") which threw an exception: System.InvalidOperationException: There is no ViewData item of type 'IEnumerable<SelectListItem>' that has the key 'myDropdown'. That's funny--I made no indication I wanted to use ViewData. Why was it looking there? Just render an empty select list for me. When I populated the list with items, it worked, but I didn't want to do that: @Html.DropDownList("myDropdown", new List<SelectListItem>() { new SelectListItem() { Text = "", Value = "" } }) I removed this dummy item in JavaScript after the AJAX call, so this worked fine, but I shouldn't have to give it a list with a dummy item when what I really want is an empty select. A bit of research with JetBrains dotPeek (helpfully recommended by Scott Hanselman) revealed the problem. Html.DropDownList requires some sort of data to render or it throws an error. The documentation hints at this but doesn't make it very clear. Behind the scenes, it checks if you've provided the DropDownList method any data. If you haven't, it looks in ViewData. If it's not there, you get the exception above. In my case, the helper wasn't doing much for me anyway, so I reverted to writing the HTML by hand (I ain't scared), and amended my best practice: When an HTML control has an associated HtmlHelper method and you're populating that control with data on the initial view, use the HtmlHelper method instead of writing by hand.

• Cloud Application Management for Platforms

  - by user756764

  Today Oracle, along with CloudBees, Cloudsoft, Huawei, Rackspace, Red Hat, and Software AG, published the Cloud Application Management for Platforms (CAMP) specification. This spec deals with application management in the context of PaaS. It defines a model (consisting of a set resources and their relationships), a REST-based API for manipulating that model, and a packaging format for getting applications (and their attendant metadata) into and out of the platform. My colleague, Mark Carlson, has already provided an excellent writeup on the spec here. The following, additional points bear emphasizing: CAMP is language, framework and platform neutral; it should be equally applicable to the task of deploying and managing Ruby on Rails applications as Java/Spring applications (as Node.js applications, etc.) CAMP only covers the interactions between a Cloud Consumer and a Cloud Provider (using the definitions of these terms provided in the NIST Cloud Computing Reference Architecture). The internal APIs used by the Cloud Provider to, for example, deploy additional platform services (e.g. a new message queuing service) are out of CAMP's scope. CAMP supports the management of the entire lifecycle of the application (e.g. start/stop, suspend/resume, etc.) not just the deployment of the components that make up the application. Complexity is the antithesis of interoperability. One of CAMP's goals is to be as broadly interoperable as possible. To this end, the authors of CAMP tried to "make things as simple as possible, but no simpler". For example, JSON is the only serialization format used in the spec (although Providers can extend this to support additional serialization formats such as XML). It remains to be seen whether we can preserve this simplicity as the spec is processed by OASIS. So far, those who have indicated an interest in collaborating on the spec seem to be of a like mind with regards to the need for simplicity. The flip side to simplicity is the knowledge that you undoubtedly missed something that is important to someone. To make up for this, CAMP is designed to be extensible. The idea is to ship what we know will work, allow implementers to extend the spec, then re-factor the spec to incorporate the most popular extensions. Anyone interested in this effort, particularly those of you using PaaS-level services, is encouraged to join the forthcoming OASIS TC. As you may have noticed, CAMP is a bit of a departure from some of the more monolithic management standards that have preceded it. The idea is to develop simple, discrete standards targeted to address specific interoperability and portability problems and tie these standards together with common patterns based on REST and HATEOAS. I'm excited to see how this idea plays out.

• My VS 2010 and ASP.NET 4 Talks Online

  - by ScottGu

  The past 7 years I’ve done an annual all day event in Arizona – organized by the most excellent Scott Cate (who always does a phenomenal job organizing the event and making it a great one). Earlier this month I visited and presented 4+ hours of content covering VS 2010, ASP.NET 4 and ASP.NET MVC 2.  NextSlide.com – a great .NET shop local to Arizona who has a great product for sharing presentations – volunteered to record the talks and publish them for free using their online presentation tool.  The recordings they did turned out really, really great – and their online player (which combines slides + camera of me + demos in one experience) is awesome.  Below you can watch the first two segments of my event – which cover VS 2010 and ASP.NET 4 – for free online using the NextSlide.com player experience.  I’ll post a link to my ASP.NET MVC 2 segment a little later in a separate blog post.  If you’ve never seen my present these talks before and are interested in the content then I’d recommend checking them out – as these recordings do a really good job capturing them. Part 1 - VS 2010 This is a 49 minute segment that starts the event and covers a bunch of the new improvements in VS 2010.  You can launch the presentation directly here or watch it inline below.  You can download powerpoint versions of my slides here. Part 2- ASP.NET 4 This 61 minute segment comes next and drills into some of the framework improvements with ASP.NET 4.  It also goes further on some of the web specific tooling improvements in VS 2010 – and towards the end demonstrates some of the great new end-to-end web deployment features provided with VS 2010 (which work for both ASP.NET Web Forms and ASP.NET MVC applications). You can launch the presentation directly here or watch it inline below: Learning More about VS 2010 and ASP.NET 4 I’ve been working on a series of blog post about VS 2010 and .NET 4.  Many of the features I covered in my two talks above are described in more detail in posts within the series.  You can read all of them here. I’ll be continuing adding to the series via my blog, so stay tuned for more in-depth posts about a bunch more new features. Hope this helps, Scott P.S. People often ask whether they can re-use the slides+demos I use in my talks for talks of their own.  The answer to this is always absolutely! No need to ask permission.  Feel free to re-use all of my slides for talks of your own. P.P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links.

• My thoughts on the future of the web with respect to flash, plugins, etc…

  - by joelvarty

  More than 10 years ago I was coding Java applets.  They were great at the time because I could reasonably expect them to run the same way in Netscape and Internet Explorer.  I could also reliably do asynchronous networking back to the server.  But then, Microsoft pulled their native Java runtime from Windows and Internet Explorer.  It got a lot harder to get applets running in people’s browsers. So I started writing ActiveX controls for IE and Java applets for Netscape. Then I switched to Flash, not for too long, but it was enough for me to see that it was a capable and curious implementation of animation, multimedia and script. I even wrote a few Silverlight controls, but then I stopped. I stepped back from all of the “richness” and “interactivity” and I thought about things like accessibility and SEO.  I wondered how my apps and sites might appear to the greater world.  I wondered how the developers I am working with, or who might be inheriting my code down the road, might interact with it. And I thought to myself, What the hell was I thinking? Those embedded controls are not what the web is about, and they run contrary to nearly all of the things that makes the web exciting and fosters innovation within and around.   Those plugins or controls, or whatever you want to refer to them as, are only stop-gaps that fill a hole in the basic HTML/Script/CSS specifications, and that’s all they should ever be used for.  Full stop.  Period.  For instance, I still make use of a nifty little flash control called SWFUpload because it lets me check file size before an upload starts.  I can do the same thing from a Silverlight control.  But rest assured, if I could do this from native javascript, I would in a second.  In fact, the only reason I chose SWFUpload over a ton of other alternatives is that it has a great javascript API so I can do (nearly) all of the UI in regular HTML.  And I ALWAYS provide a non-flash alternative for uploading, and for the rest of any website where the designer has insisted on some piece of creativity that requires flash (usually because the designer is also the flash developer, but that’s an aside…). The web is about openness, and about exposing that openness in such a way that it can be taken advantage of as a small part of a greater whole.  Sure we need security and authentication and ssl and all that stuff, but for me, its something more profound.  For me, the majority of what the web is, is about exposing something that delivers meaning.  What meaning can we derive from an <object> tag?   more later - joel
