• Devoxx 2011: Java EE 6 Hands-on Lab Delivered

  - by arungupta

  I, along with Alexis's help, delivered a Java EE 6 hands-on lab to a packed room of about 40+ attendees at Devoxx 2011. The lab was derived from the OTN Developer Days 2012 version but added lot more content to showcase several Java EE 6 technologies. The problem statement from the lab document states: This hands-on lab builds a typical 3-tier Java EE 6 Web application that retrieves customer information from a database and displays it in a Web page. The application also allows new customers to be added to the database as well. The string-based and type-safe queries are used to query and add rows to the database. Each row in the database table is published as a RESTful resource and is then accessed programmatically. Typical design patterns required by a Web application like validation, caching, observer, partial page rendering, and cross-cutting concerns like logging are explained and implemented using different Java EE 6 technologies. The lab covered Java Persistence API 2, Servlet 3, Enterprise JavaBeans 3.1, JavaServer Faces 2, Java API for RESTful Web Services 1.1, Contexts and Dependency Injection 1.0, and Bean Validation 1.0 over 47 pages of detailed self-paced instructions. Here is the complete Table of Contents: The lab can be downloaded from here and requires only NetBeans IDE "All" or "Java EE" version, which includes GlassFish anyway. All the feedback received from the lab has been incorporated in the instructions and bugs filed (Updated 49559, 205232, 205248, 205256). 80% of the attendees could easily complete the lab and some even completed in much less than 3 hours. That indicates that either more content needs to be added to the lab or the intellectual level of the attendees at the conference was pretty high. I think the lab has enough content for 3 hours but we moved at a much more faster pace so I conclude on the latter. Truly a joy to conduct a lab to 40 Devoxxians! Another related lab that might be handy for folks is "Develop, Deploy, and Monitor your Java EE 6 applications using GlassFish 3.1 Cluster". It explains how: Create a 2-instance GlassFish cluster Front-end with a Web server and a load balancer Demonstrate session replication and fail over Monitor the application using JavaScript The complete lab instructions and source code are available and you can try them. I plan to continue evolving the contents for the Java EE 6 hands-on lab to cover more technologies and features and will announce them on this blog. Let me know on what else would you like to see in the future versions.

• Databases and Beer

  - by Johnm

  It is a bit of a no-brainer: Include the word "beer" in a subject line of an e-mail or blog post title and you can be certain that it will be read. While there are times this practice might be a ploy to increase readership, it is not the case for this blog post. There is inspiration that can be drawn from other industries to which we, as database professionals, can apply in our industry. In this post I will highlight one of my favorite participants of the brewing industry. The Boston Beer Company started in the 1970s in Boston, Massachusetts. Others may be more familiar with this company through their Samuel Adams Boston Lager and other various seasonal beers. I am continually inspired by their commitment to mastery of the brewing process to which they evangelize frequently in their commercials. They also are continually in pursuit of pushing the boundaries of beer as we know it while working within traditional constraints. A recent example of this is their collaboration with Weihenstephan Brewery of Munich, Germany to produce the soon to be released Infinium beer. This beer, while brewed as an ale, is touted as something closer to something like Champaign - all while complying with the Reinheitsgebot. The Reinheitsgebot is also known as the "German Beer Purity Law" which was originated in 1516. This law states that beer is to consist of water, barley, hops and yeast. That's it. Quite a limiting constraint indeed. and yet, The Boston Beer Company pushed forward. Much like the process of brewing, the discipline of database design and architecture is one that is continually in process and driven by the pursuit of mastery. While we do not have purity laws to constrain us, we have many other types: best practices, company policies, government regulations, security and budgets. Through our fellow comrades, we discuss the challenges and constraints in which we operate. We boil down the principles and theories that define our profession. We reassemble these into something that is complementary to the business needs that we must fulfill. As a result, it is not uncommon to see something amazingly innovative in a small business who is pushing the boundaries of their database well beyond its intended state. It is equally common to see innovation in the use of features available in the more advanced features of databases that are found in large businesses. The tag line for The Boston Beer Company is: "Take Pride In Your Beer.", I would like to offer an alternative and say "Take Pride In Your Database." So, As you pour your next Boston Lager into a frosted glass, consider those who spend their lives mastering the craft of brewing and strive to interject their spirit into everything that you do as a database professional. Cheers!

• Javascript A* path finding ENEMY MOVEMENT in 3D environment

  - by faiz

  iam trying to implement pathfinding algorithm using PATHFINDING.JS in 3D world using webgl. iam have made a matrix of 200x200. and placed my enemy(swat) in it .iam confused in implmenting the path. i have tried implementing the path by compparing the value of each array value with swat's position . it works ! but ** THE ENEMY KEEPS GOING FROM THE UNWALKABLE AREA OF MY MATRIX....like the enemy should not move from 119,100(x=119,z=100) but its moving from that co-ordinate too ..... can any one help me out in this regard .. *prob facing :* enemy (swat character keeps moving from the wall /unwalkable area) wanted solution : enemy does not move from the unwalkable path.. ** function draw() { grid = new PF.Grid(200, 200); grid.setWalkableAt( 119,100, false); grid.setWalkableAt( 107,100, false); grid.setWalkableAt( 103,104, false); grid.setWalkableAt( 103,100, false); grid.setWalkableAt( 135,100, false); grid.setWalkableAt( 103,120, false); grid.setWalkableAt( 103,112, false); grid.setWalkableAt( 127,100, false); grid.setWalkableAt( 123,100, false); grid.setWalkableAt( 139,100, false); grid.setWalkableAt( 103,124, false); grid.setWalkableAt( 103,128, false); grid.setWalkableAt( 115,100, false); grid.setWalkableAt( 131,100, false); grid.setWalkableAt( 103,116, false); grid.setWalkableAt( 103,108, false); grid.setWalkableAt( 111,100, false); grid.setWalkableAt( 103,132, false); finder = new PF.AStarFinder(); f1=Math.abs(first_person_controller.position.x); f2=Math.abs(first_person_controller.position.z); ff1=Math.round(f1); ff2=Math.round(f2); s1=Math.abs(swat.position.x); s2=Math.abs(swat.position.z); ss1=Math.round(s1); ss2=Math.round(s1); path = finder.findPath(ss1,ss2,ff1,ff2, grid); size=path.length-1; Ai(); } function Ai(){ if (i<size) { if (swat.position.x >= path[i][0]) { swat.position.x -= 0.3; if(Math.floor(swat.position.x) == path[i][0]) { i=i+1; } } else if(swat.position.x <= path[i][0]) { swat.position.x += 0.3; if(Math.floor(swat.position.x) == path[i][0]) { i=i+1; } } } if (j<size) { if((Math.abs(swat.position.z)) >= path[j][1]) { swat.position.z -= 0.3; if(Math.floor(Math.abs(swat.position.z)) == path[j][1]) { j=j+1; } } else if((Math.abs(swat.position.z)) <= path[j][1]) { swat.position.z += 0.3; if(Math.floor(Math.abs(swat.position.z)) == path[j][1]) { j=j+1; } } } }

• Using machine learning to aim mirrors in a solar array?

  - by Buttons840

  I've been thinking about solar collectors where several independent mirrors to focus the light on a solar collector, similar to the following design from Energy Innovations. Because there will be flaws in the assembly of this solar array, I am proceeding with the following assumptions (or lack thereof): The software knows the "position" of each mirror, but doesn't know how this position relates to the real world or to other mirrors. This will account for poor mirror calibration or other environmental factors which may effect one mirror but not the others. If a mirror moves 10 units in one direction, and then 10 units in the opposite direction, it will end up where it originally started. I would like to use machine learning to position the mirrors correctly and focus the light on the collector. I expect I would approach this as an optimization problem, optimizing the mirror positions to maximize the heat inside the collector and the power output. The problem is finding a small target in a noisy high-dimensional space (considering each mirror has 2 axis of rotation). Some of the problems I anticipate are: cloudy days, even if you stumble upon the perfect mirror alignment, it might be cloudy at the time noisy sensor data the sun is a moving target, it moves along a path, and follows a different path every day - although you could calculate the exact position of the sun at any time, you wouldn't know how that position relates to your mirrors My question isn't about the solar array, but possible machine learning techniques that would help in this "small target in a noisy high dimensional-space" problem. I mentioned the solar array because it was the catalyst for this question and a good example. What machine learning techniques can find such a small target in a noisy high-dimensional space? EDIT: A few additional thoughts: Yes, you can calculate the suns position in the real world, but you don't know how the mirrors position is related to the real world (unless you've learned it somehow). You might know the suns azimuth is 220 degrees, and the suns elevation is 60 degrees, and you might know a mirror is at position (-20, 42); now tell me, is that mirror correctly aligned with the sun? You don't know. Lets assume you have some very sophisticated heat measurements, and you know "with this heat level, there must be 2 mirrors correctly aligned". Now the question is, which two mirrors (out of 25 or more) are correctly aligned? One solution I considered was to approximate the correct "alignment function" using a neural network which would take the suns azimuth and elevation as input and output a large array with 2 values for each mirror which correspond to the 2 axis of each mirror. I'm not sure what the best training method is though.

• CIO's Corner: Achieving a Balance

  - by Michelle Kimihira

  Author: Rick Beers Senior Director, Product Management, Oracle Fusion Middleware All too often, a CIO is unfairly characterized as either technology-focused or business-focused; as more concerned with either infrastructure performance or business excellence. It seems to me that this completely misses the point. I have long thought that a CIO has probably the most complex C-level position in an enterprise, one that requires an artful balance among four entirely different constituencies, often with competing values and needs. How a CIO balances these is the single largest determinant of success. I was reminded of this while reading the excellent interview of Mark Hurd by CNBC’s Maria Bartiromo in a recent issue of USATODAY (Bartiromo: Oracle's Hurd is in tech sweet spot). The interview covers topics such as Big Data, Leadership and Oracle’s growth strategy. But the topic that really got my interest, and reminded me of the need for balance, was on IT spending trends, in which Mark Hurd observed, “…budgets are tight. What most of our customers have today is both an austerity plan to save money and at the same time a plan to reapply that money to innovation. There isn't a customer we have that doesn't have an austerity plan and an innovation plan.” In an era of economic uncertainty, and an accelerating pace of business change, this is probably the toughest balance a CIO must achieve. Yet for far too many IT organizations, operating costs consume over 75% of their budgets, leaving precious little for innovation and investment in business-critical technology programs. I have found that many CIO’s are trapped by their enterprise systems platforms, which were originally architected for Standardization, Compliance and tightly integrated linear Workflows. Yes, these traits are still required for specific reasons and cannot be compromised. But they are no longer enough. New demands are emerging: the explosion in the volume and diversity of Data, the Consumerization of IT, the rise of Social Media, and the need for continual Business Process Reengineering. These were simply not the design criteria for Enterprise 1.0 and attempting to leverage them with current systems platforms results in an escalation in complexity and a resulting increase in operating costs for many IT organizations. This is the cost vs investment trap and what most constrains CIO’s from achieving the balance they need. But there is a way out of this trap. Enterprise 2.0 represents an entirely new enterprise systems architecture, one that is ‘Business-Centric’ rather than ‘ERP Centric’, which defined the architecture of Enterprise 1.0. Oracle’s best in class suite of Fusion Middleware Products enables a layered approach to enterprise systems architectures that provides the balance that an enterprise needs. The most exciting part of all this? The bottom two layers are focused upon reducing costs and the upper two layers provide business value and innovation. Finally, the Balance a CIO needs.  Additional Information Product Information on Oracle.com: Oracle Fusion Middleware Follow us on Twitter and Facebook Subscribe to our regular Fusion Middleware Newsletter

• Win7 is not a tablet OS, no matter what the boys in Redmond think.

  - by John Conwell

  Despite what execs at Microsoft think, Windows 7 is NOT a tablet OS.  Just because you can install some software (or OS) on a device, doesn't mean that device is meant to run that software.  This seems to be the step that the non-engineer execs at Microsoft have seem to not understood.  In order to seamlessly work with a device, the software needs to be designed with that device in mind.  That has been the problem with the Windows PDA platform, the Windows Mobil platform, and now with trying to force fit Windows 7 on a tablet.  Its just not designed for that style of interaction.   Windows is designed to be interacted with via a mouse and keyboard.  In fact, it is brilliant at that.  But, It is NOT designed to be interacted with by your fingers.  And that is why the Windows tablet failed 10 years ago, and why it will fail today.  Its not the hardware's fault like Microsoft claimed 10 years ago.  Its the User Interaction design that failed. And this is why the iPhone and Android OS's work wonderfully on a tablet.  The user interaction was designed for small screens, navigated by big fat fingers.  I love these OS's and how I interact with them.  And when I play with a touch screen Windows 7 device, I am feel like I'm playing with a brittle wana-be.  And its not the hardware's fault.  The touchscreen is very responsive.  I actually like the hardware.  But the OS and the software are just not designed to be interacted with, with my big fat fingers.  In order to be successful, Microsoft needs to start from scratch, and build a platform AND SOFTWARE specifically for use by fingers.  Thats why everyone was so excited when they though Microsoft was going to release the Courier tablet.  Because it looked like a totally different platform.  Something that might actually work.  But Windows 7...I hate to burst your bubble, but you are not a touch platform.

• One Week To Go: OTN Architect Day: Cloud Computing

  - by Bob Rhubart

  One week remains until OTN Architect Day: Cloud Computing kicks of at the spectacular Oracle HQ campus in Redwood Shores, CA. The event is free, and there is still time to register. When: Tuesday July 9, 2013 8:30am - 12:30pm Where: Oracle Conference Center350 Oracle Pkwy Redwood City, CA 94065 Register now. It's free! Here's the latest update to the event agenda: 8:30am - 9:00am Registration and Continental Breakfast 9:00am - 9:45am Keynote 21st Century IT | Dr. James Baty VP, Global Enterprise Architecture Program, Oracle Imagine a time long, long ago. A time when servers were certified and dedicated to specific applications, when anything posted on an enterprise web site was from restricted, approved channels, and when we tried to limit the growth of 'dirty' data and storage. Today, applications are services running in the muti-tenant hybrid cloud. Companies beg their customers to tweet them, friend them, and publicly rate their products. And constantly analyzing a deluge of Internet, social and sensor data is the key to creating the next super-successful product, or capturing an evil terrorist. The old IT architecture was planned, dedicated, stable, controlled, with separate and well-defined roles. The new architecture is shared, dynamic, continuous, XaaS, DevOps. This keynote session describes the challenges and opportunities that the new business / IT paradigms present to the IT architecture and architects. 9:45am - 10:30am Technical Session Oracle Cloud: A Case Study in Building a Cloud | Anbu Krishnaswami Enterprise Architect, Oracle Building a Cloud can be challenging thanks to the complex requirements unique to Cloud computing and the massive scale typically associated with Cloud. Cloud providers can take an Infrastructure as a Service (IaaS) approach and build a cloud on virtualized commodity hardware, or they can take the Platform as a Service (PaaS) path, a service-oriented approach based on pre-configured, integrated, engineered systems. This presentation uses the Oracle Cloud itself as a case study in the use of engineered systems, demonstrating how the technical design of engineered systems is leveraged for building PaaS and SaaS Cloud services and a Cloud management infrastructure. The presentation will also explore the principles, patterns, best practices, and architecture views provided in Oracle's Cloud reference architecture. 10:30 am -10:45 am Break 10:45am-11:30am Technical Session Database as a Service | Markus Michalewicz Senior Principal Product Manager Oracle Real Application Clusters (RAC) New applications are now commonly built in a Cloud model, where the database is consumed as a service, and many established business processes are beginning to migrate to database as a service (DBaaS). This adoption of DBaaS is made possible by the availability of new capabilities in the database that enable resource pooling, dynamic resource management, model-based provisioning, metered use, and effective quality-of-service controls. This session will examine the catalog of database services at a large commercial bank to understand how these capabilities are enabling DBaaS for a wide range of needs within the enterprise. 11:30 am - 12:00 pm Panel Q&A Dr. James Baty, Anbu Krishnaswami, and Markus Michalewicz respond to audience questions.

• How do software projects go over budget and under-deliver?

  - by Carlos

  I've come across this story quite a few times here in the UK: NHS Computer System Summary: We're spunking £12 Billion on some health software with barely anything working. I was sitting the office discussing this with my colleagues, and we had a little think about. From what I can see, all the NHS needs is a database + middle tier of drugs/hospitals/patients/prescriptions objects, and various GUIs for doctors and nurses to look at. You'd also need to think about security and scalability. And you'd need to sit around a hospital/pharmacy/GPs office for a bit to figure out what they need. But, all told, I'd say I could knock together something with that kind of structure in a couple of days, and maybe throw in a month or two to make it work in scale. * If I had a few million quid, I could probably hire some really excellent designers to make a maintainable codebase, and also buy appropriate hardware to run the system on. I hate to trivialize something that seems to have caused to much trouble, but to me it looks like just a big distributed CRUD + UI system. So how on earth did this project bloat to £12B without producing much useful software? As I don't think the software sounds so complicated, I can only imagine that something about how it was organised caused this mess. Is it outsourcing that's the problem? Is it not getting the software designers to understand the medical business that caused it? What are your experiences with projects gone over budget, under delivered? What are best practices for large projects? Have you ever worked on such a project? EDIT *This bit seemed to get a lot of attention. What I mean is I could probably do this for say, 30 users, spending a few tens of thousands of pounds. I'm not including stuff I don't know about the medical industry and government, but I think most people who've been around programming are familiar with that kind of database/front end kind of design. My point is the NHS project looks like a BIG version of this, with bells and whistles, notably security. But surely a budget millions of times larger than mine could provide this?

• C++ Accelerated Massive Parallelism

  - by Daniel Moth

  At AMD's Fusion conference Herb Sutter announced in his keynote session a technology that our team has been working on that we call C++ Accelerated Massive Parallelism (C++ AMP) and during the keynote I showed a brief demo of an app built with our technology. After the keynote, I go deeper into the technology in my breakout session. If you read both those abstracts, you'll get some information about what C++ AMP is, without being too explicit since we published the abstracts before the technology was announced. You can find the official online announcement at Soma's blog post. Here, I just wanted to capture the key points about C++ AMP that can serve as an introduction and an FAQ. So, in no particular order… C++ AMP lowers the barrier to entry for heterogeneous hardware programmability and brings performance to the mainstream, without sacrificing developer productivity or solution portability. is designed not only to help you address today's massively parallel hardware (i.e. GPUs and APUs), but it also future proofs your code investments with a forward looking design. is part of Visual C++. You don't need to use a different compiler or learn different syntax. is modern C++. Not C or some other derivative. is integrated and supported fully in Visual Studio vNext. Editing, building, debugging, profiling and all the other goodness of Visual Studio work well with C++ AMP. provides an STL-like library as part of the existing concurrency namespace and delivered in the new amp.h header file. makes it extremely easy to work with large multi-dimensional data on heterogeneous hardware; in a manner that exposes parallelization. introduces only one core C++ language extension. builds on DirectX (and DirectCompute in particular) which offers a great hardware abstraction layer that is ubiquitous and reliable. The architecture is such, that this point can be thought of as an implementation detail that does not surface to the API layer. Stay tuned on my blog for more over the coming months where I will switch from just talking about C++ AMP to showing you how to use the API with code examples… Comments about this post welcome at the original blog.

• Creating a Strong Bridge to the Post PC World

  - by Webgui

  Moving from location to location requires strong roads.  When crossing a barrier though, like a body of water or valley, we are required to build a strong bridge to get us from point A to point B in a way that is fast, safe, and easy.Yet we are not talking here about driving a car or riding a bus.  As we in the computing world are evidencing the move to the post-PC era, modernizing and migrating legacy applications to harness the power of HTML5 web, cloud and mobile is one of the most difficult challenges enterprises have faced.  Constant technological changes have weakened the business value of legacy systems, which have been developed over the years through huge investments.  There are several risks of course in this move.  Do you choose to simply rewrite code of legacy apps and transform them to HTML5 one by one?  This is quite expensive (according to research firm Gartner, the cost is $6 - $26 per line of code).  Of course, the pace of the rewriting process is very slow – around 170 lines per day for each developer – which slows down business productivity in a world in which no organization can afford to fall behind.  Other questions include whether the new cloud-based apps will have the same functionality as the trusted applications that worked for you for years.  How will the user experience be affected?  And of course, what about data security?  So we are faced with the challenge of building a sturdy bridge to stabilize our move in order to allow us to confidently and easily move our legacy applications into the post-PC era.   We at Gizmox are excited to release the first downloadable Community Technology Preview (CTP) of our Instant CloudMove Transposition Studio.Developers: To download the tool, and try it out for yourself, please visit http://www.visualwebgui.com/download.aspx.The CTP is the first and only tool-based solution allowing any Microsoft Visual Studio developer to extend VB6 and .NET enterprise client/server applications into HTML5 web, cloud and mobile applications, including the ability to upgrade their code and UI while doing so.   It is the only solution to fully replicate enterprise desktop applications behavior in the post-PC era.  With Instant CloudMove, the transposed application is available on any mobile or tablet device, browser and across any client operating system. Moreover, the extended application logic and data remains on the server behind the fire-wall and therefore the application’s front end is secured-by-design.   We would love for you to try out the tool for yourselves and let us know what you think.  How are you finding the move?

• Introducing Agile development after traditional project inception

  - by Riggy

  About a year and a half ago, I entered a workplace that claimed to do Agile development. What I learned was that this place has adopted several agile practices (such as daily standups, sprint plannings and sprint reviews) but none of the principles (just in time / just good enough mentality, exposing failure early, rich communication). I've now been tasked with making the team more agile and I've been assured that I have complete buy-in from the devs and the business team. As a pilot program, they've given me a project that just completed 15 months of requirements gathering, has a 110 page Analysis & Design document (to be considered as "written in stone"), and where I have no access to the end users (only to the committee made up of the users' managers who won't actually be using the product). I started small, giving them a list of expected deliverables for the first 5 sprints (leaving the future sprints undefined), a list of goals for the first sprint, and I dissected the A&D doc to get enough user stories to meet the first sprint's goals. Since then, they've asked why we don't have all the requirements for all the sprints, why I haven't started working on stuff for the third sprint (which they consider more important but is based off of the deliverables of the first 2 sprints) and are pressing for even more documentation that my entire IT team considers busy-work or un-related to us (such as writing the user manual up-front, documenting all the data fields from all the sprints up front, and more "up-front" work). This has been pretty rough for me as a new project manager, but there are improvements I have effectively implemented such as scrumban for story management, pair programming, and having the business give us customer acceptance tests up front (as part of the requirements documentation). So my questions are: What can I do to more effectively introduce change to a resistant business? Are there other practices that I can introduce on the IT side to help show the business the benefits of agile? The burden of documentation is strangling us - the business still sees it as a risk management strategy instead of as a risk. What can we do to alleviate their documentation concerns and demands (specifically the quantity of documentation and their need for all of it up front)? We are in a separate building from our business, about 3 blocks away and they refuse to have their people on the project co-habitate b/c that person "won't be able to work on their other projects while they're at our building." They expect us to always go over there and to bundle our questions so that we can ask them all at once and not waste that person's time with "constant interruptions." What can we do to get richer communication from them? Any additional advice would also be appreciated. Thanks!

• viable part-time career in IT/programming?

  - by Rider

  Hi, I'd like to ask for some career advice from you people. Is there a viable job/career that can be done in programming/IT for the long term? Right now, I am thinking about website (PHP?) developer path. My background: I have a degree in computer science and have been a programmer/system analyst for almost 10 years. Lately I took a big break from programming and studied for a B.arch. degree (yes architecture), only to discover that architecture offers zero (0) jobs where I'm from, for 3 years already (and no, I am not going to move and the grass in not greener in other places). I have never been particularly interested in programming, in fact I was bored by it. But I was always quite good at both programming and system analysis, and very valued by practically all my employers. On the other hand, I have never been valued or offered a good job in any other field (although I can do many things, like design, architecture, translations, documentation, teaching, etc etc.) I guess the human component has been always more important for me in programming jobs - I value all the good people I worked with, but not projects. However, I have about zero skills or desire to be a project manager. I also have close to zero skills for selling myself. I like it best when I can do "my thing", have my niche, have an ownership of some project. Right now my career perspective is to do part time programming and to part time teach yoga. I have already started the yoga teaching part. Do you think that part time programming is viable? And what niche works best for that? I have considered web development, QA, or software development in a company like I did before. However, my fear is that when you do programming part-time, you get the most boring coding work, only to see your colleagues move to more interesting projects and up their respective career ladders. I also fear that part-timers are not especially needed either. And, since I don't share much enthusiasm at programming, I'd rather not be around young programmers boiling with geeky enthusiasm about coding, but rather QA mindset with people from different backgrounds and life paths might work better for me. Thanks for any advice, --Rider

• A Facelift for Fusion

  - by Richard Lefebvre

  It's simple. It's modern. It was the buzz at OpenWorld in San Francisco. See what the UX team has been up to and what customers are going to love. At OpenWorld 2012, the Oracle Applications User Experience (UX) team unveiled the new face of Fusion Applications. You might have seen it in sessions presented by Chris Leone, Anthony Lye, Jeremy Ashley and others or you may have gotten a look on the demogrounds. Why are we delivering a new face for Fusion Applications? "Because," says Ashley, vice president of the Oracle Applications User Experience team, "we want to provide a simple, modern, productive way for users to complete their top quick-entry tasks. The idea is to provide a clear, productive user experience that is backed by the full functionality of Fusion Applications." The first release of the new face of Fusion focuses on three types of users. It provides a fully functional gateway to Fusion Applications for: ·         New and casual users who need quick access to self-service tasks ·         Professional users who need fast access to quick-entry, high-volume tasks ·         Users who are looking for a way to quickly brand their portal for employees The new face of Fusion allows users to move easily from navigation to action, Ashley said, and it has been designed for any device -- Mac, PC, iPad, Android, SmartBoard -- in the browser. How Did We Build It? The new face of Fusion essentially is a custom shell, developed by the Apps UX team, and a set of page templates that embodies a simple design aesthetic. It's repeatable, providing consistency across its pages, and the need for training is little to zero. More specifically, the new face of Fusion has been built on ADF. The Applications UX team created pages in JDeveloper using local tasks flows bound to existing view objects. Three new components were commissioned from ADF and existing Fusion components were re-skinned to deliver a simple, modern user experience. It really is that simple - and to prove that point, we've been sharing our new face of Fusion story on several Oracle channels such as this one. If you want to learn more, check OpenWorld presentation on the Fusion Learning Center.

• Why CoffeeScript is tough to maintain

  - by Renso

  I recently started trying out CoffeeScript only to find out that it caused more headaches. The abstraction level of jQuery was perfect, it did not dictate to coders how to design their code, it just works. However, I recently posted a request to the CoffeeScript team to consider introducing curly braces to help with more complex code to control the flow of logic. For example a if-then-else with many nested levels can be near impossible to debug without tracing through it when using CoffeeScript. Also with IDEs like Visual Studio, regular JavaScript intellicense and auto-formatting make it easy to appropriate indent nested levels without any work on the part of the developer and reading it is not that hard, especially with some extensions that show vertical lines in the code editor to help see what is nested within what part of the code.However with CoffeeScript that is not the case. The samples given in the CoffeeScript web site are of course just simple examples to explain the features and one gets excited pretty quick over the powerful shortcuts. I tried to convert a piece of JavaScript over to CoffeeScript and gave up since you need to first of all remove ALL non CoffeeScript coding constructs for it to even compile. However js2coffee can help with that. However to keep track of nested levels became something that was simply not manageable using CoffeeScript.Furthermore, any coding language that controls the flow of logic by indentation is extremely dangerous for obvious reasons. I liked CoffeeScript a lot, but the fact that the logical flow of the code is controlled by how much you indent code, spaces or tabs, is not reliable as there is no way the programmer has an easy way of knowing what parts of the code will get hit when the code spans a page.When I suggested introducing curly braces in CoffeeScript the team, one contributor advised me that my code needs to be re-designed! Needless to say that is absurd. When I included a piece of the code he asked my if it was legacy code. It's like saying to a Java programmer, sorry you cannot use Java because we don't agree with how you write your code.jashkenas from the CoffeeScript blog gave some great suggestions and made the point that introducing curly braces would be very problematic for them as they use them to denote objects. Makes sense, but I would still love to see some way to replace code flow control with spaces and indentation to something more concrete and human readable.

• Games at Work Part 2: Gamification and Enterprise Applications

  - by ultan o'broin

  Gamification and Enterprise Applications In part 1 of this article, we explored why people are motivated to play games so much. Now, let's think about what that means for Oracle applications user experience. (Even the coffee is gamified. Acknowledgement @noelruane. Check out the Guardian article Dublin's Frothing with Tech Fever. Game development is big business in Ireland too.) Applying game dynamics (gamification) effectively in the enterprise applications space to reflect business objectives is now a hot user experience topic. Consider, for example, how such dynamics could solve applications users’ problems such as: Becoming familiar or expert with an application or process Building loyalty, customer satisfaction, and branding relationships Collaborating effectively and populating content in the community Completing tasks or solving problems on time Encouraging teamwork to achieve goals Improving data accuracy and completeness of entry Locating and managing the correct resources or information Managing changes and exceptions Setting and reaching targets, quotas, or objectives Games’ Incentives, Motivation, and Behavior I asked Julian Orr, Senior Usability Engineer, in the Oracle Fusion Applications CRM User Experience (UX) team for his thoughts on what potential gamification might offer Oracle Fusion Applications. Julian pointed to the powerful incentives offered by games as the starting place: “The biggest potential for gamification in enterprise apps is as an intrinsic motivator. Mechanisms include fun, social interaction, teamwork, primal wiring, adrenaline, financial, closed-loop feedback, locus of control, flow state, and so on. But we need to know what works best for a given work situation.” For example, in CRM service applications, we might look at the motivations of typical service applications users (see figure 1) and then determine how we can 'gamify' these motivations with techniques to optimize the desired work behavior for the role (see figure 2). Description of Figure 1 Description of Figure 2 Involving Our Users Online game players are skilled collaborators as well as problem solvers. Erika Webb (@erikanollwebb), Oracle Fusion Applications UX Manager, has run gamification events for Oracle, including one on collaboration and gamification in Oracle online communities that involved Oracle customers and partners. Read more... However, let’s be clear: gamifying a user interface that’s poorly designed is merely putting the lipstick of gamification on the pig of work. Gamification cannot replace good design and killer content based on understanding how applications users really work and what motivates them. So, Let the Games Begin! Gamification has tremendous potential for the enterprise application user experience. The Oracle Fusion Applications UX team is innovating fast and hard in this area, researching with our users how gamification can make work more satisfying and enterprises more productive. If you’re interested in knowing more about our gamification research, sign up for more information or check out how your company can get involved through the Oracle Usability Advisory Board.

• the unity aspect ratio script looks good in computer but not in android phones

  - by Pooya Fayyaz

  I'm developing a game for android devices.and i have a script that solve the ratio problem but i have a problem in this code.and i dont know why.it looks perfect in computer even resize the game screen but in mobile phones have a problem.my game runs in landscape mode.this is the script : using UnityEngine; using System.Collections; using System.Collections.Generic; public class reso : MonoBehaviour { void Update() { // set the desired aspect ratio (the values in this example are // hard-coded for 16:9, but you could make them into public // variables instead so you can set them at design time) float targetaspect = 16.0f / 9.0f; // determine the game window's current aspect ratio float windowaspect = (float)Screen.width / (float)Screen.height; // current viewport height should be scaled by this amount float scaleheight = windowaspect / targetaspect; // obtain camera component so we can modify its viewport Camera camera = GetComponent<Camera>(); // if scaled height is less than current height, add letterbox if (scaleheight < 1.0f && Screen.width <= 490 ) { Rect rect = camera.rect; rect.width = 1.0f; rect.height = scaleheight; rect.x = 0; rect.y = (1.0f - scaleheight) / 2.0f; camera.rect = rect; } else // add pillarbox { float scalewidth = 1.0f / scaleheight; Rect rect = camera.rect; rect.width = scalewidth; rect.height = 1.0f; rect.x = (1.0f - scalewidth) / 2.0f; rect.y = 0; camera.rect = rect; } } } i figure that my problem occur in this part of the script: if (scaleheight < 1.0f) { Rect rect = camera.rect; rect.width = 1.0f; rect.height = scaleheight; rect.x = 0; rect.y = (1.0f - scaleheight) / 2.0f; camera.rect = rect; } and its look like this in my mobile phone in portrait: and in landscape mode:

• #SSAS #Tabular Workshop and Community Events in Netherlands and Denmark

  - by Marco Russo (SQLBI)

  Next week I will finally start the roadshow of the SSAS Tabular Workshop, a 2-day seminar about the new BISM Tabular model for Analysis Services that has been introduced in SQL Server 2012. During these roadshows, we always try to arrange some speeches at local community events in the evening - we already defined for Copenhagen, we have some logistic issue in Amsterdam that we're trying to solve. Here is the timetable: Netherlands SSAS Workshop in Amsterdam, NL – April 16-17, 2012 2-day seminar, I and Alberto will be the trainers for this event, register here We're trying to manage a Community event but we still don't have a confirmation, stay tuned        Denmark SSAS Workshop in Copenhagen, DK – April 26-27, 2012 2-day seminar, I and Alberto will be the trainers for this event, register here Community event on April 26, 2012 This event will run in Hellerup, at Microsoft venue All details available here: http://msbip.dk/events/26/msbip-mode-nr-5/ People from Sweden are welcome! Just register to this private group on LinkedIn in order to announce your presence, so we’ll know how many people will attend In community events we’ll deliver two speeches – here are the descriptions: Inside xVelocity (VertiPaq) PowerPivot and BISM Tabular models in Analysis Services share a great columnar-based database engine called xVelocity in-memory analytics engine (VertiPaq). If you want to improve performance and optimize memory used, you have to understand some basic principles about how this engine works, how data is compressed, and how you can design a data model for better optimization. Prepare yourself to change your mind. xVelocity optimization techniques might seem counterintuitive and are absolutely different than OLAP and SQL ones! Choosing between Tabular and Multidimensional You have a new project and you have to make an important decision upfront. Should you use Tabular or Multidimensional? It is not easy to answer, because sometime there is a clear choice, but most of the times both decisions might be correct, at least at the beginning. In this session we’ll help you making an informed decision, correctly evaluating pros and cons of each one according to common scenarios, considering both short-term and long-term consequences of your choice. I hope to meet many people in this first dates. We have many other events coming in May and June, including an online event (for US time zones), and you can also attend our PreCon Day at TechEd US in Orland (PRC06) or TechEd Europe in Amsterdam. I’ll be a good customer for airline companies in the next three months! I’m just sorry that I hadn’t time to write other articles in the last month, but I’m accumulating material that I will need to write down during some flight – stay tuned…

• Common SOA Problems by C2B2

  - by JuergenKress

  SOA stands for Service Oriented Architecture and has only really come together as a concrete approach in the last 15 years or so, although the concepts involved have been around for longer. Oracle SOA Suite is based around the Service Component Architecture (SCA) devised by the Open SOA collaboration of companies including Oracle and IBM. SCA, as used in SOA suite, is designed as a way to crystallise the concepts of SOA into a standard which ensures that SOA principles like the separation of application and business logic are maintained. Orchestration or Integration? A common thing to see with many people who are beginning to either build a new SOA based infrastructure, or move an old system to be service oriented, is confusion in the purpose of SOA technologies like BPEL and enterprise service buses. For a lot of problems, orchestration tools like BPEL or integration tools like an ESB will both do the job and achieve the right objectives; however it’s important to remember that, although a hammer can be used to drive a screw into wood, that doesn’t mean it’s the best way to do it. Service Integration is the act of connecting components together at a low level, which usually results in a single external endpoint for you to expose to your customers or other teams within your organisation – a simple product ordering system, for example, might integrate a stock checking service and a payment processing service. Process Orchestration, however, is generally a higher level approach whereby the (often externally exposed) service endpoints are brought together to track an end-to-end business process. This might include the earlier example of a product ordering service and couple it with a business rules service and human task to handle edge-cases. A good (but not exhaustive) rule-of-thumb is that integrations performed by an ESB will usually be real-time, whereas process orchestration in a SOA composite might comprise processes which take a certain amount of time to complete, or have to wait pending manual intervention. BPEL vs BPMN For some, with pre-existing SOA or business process projects, this decision is effectively already made. For those embarking on new projects it’s certainly an important consideration for those using Oracle SOA software since, due to the components included in SOA Suite and BPM Suite, the choice of which to buy is determined by what they offer. Oracle SOA suite has no BPMN engine, whereas BPM suite has both a BPMN and a BPEL engine. SOA suite has the ESB component “Mediator”, whereas BPM suite has none. Decisions must be made, therefore, on whether just one or both process modelling languages are to be used. The wrong decision could be costly further down the line. Design for performance: Read the complete article here.

• Why do camera's aspect ratio look good on computer but not on Android devices?

  - by Pooya Fayyaz

  I'm developing a game for Android devices and I have a script that solves the aspect-ratio problem for computer screens but not for my intended target platform. It looks perfect on computer, even when re-sizing the game screen, but not when running my game in landscape mode on mobile phones. This is my script using UnityEngine; using System.Collections; using System.Collections.Generic; public class reso : MonoBehaviour { void Update() { // set the desired aspect ratio (the values in this example are // hard-coded for 16:9, but you could make them into public // variables instead so you can set them at design time) float targetaspect = 16.0f / 9.0f; // determine the game window's current aspect ratio float windowaspect = (float)Screen.width / (float)Screen.height; // current viewport height should be scaled by this amount float scaleheight = windowaspect / targetaspect; // obtain camera component so we can modify its viewport Camera camera = GetComponent<Camera>(); // if scaled height is less than current height, add letterbox if (scaleheight < 1.0f && Screen.width <= 490 ) { Rect rect = camera.rect; rect.width = 1.0f; rect.height = scaleheight; rect.x = 0; rect.y = (1.0f - scaleheight) / 2.0f; camera.rect = rect; } else // add pillarbox { float scalewidth = 1.0f / scaleheight; Rect rect = camera.rect; rect.width = scalewidth; rect.height = 1.0f; rect.x = (1.0f - scalewidth) / 2.0f; rect.y = 0; camera.rect = rect; } } } I figured that my problem occurs in this part of the script: if (scaleheight < 1.0f) { Rect rect = camera.rect; rect.width = 1.0f; rect.height = scaleheight; rect.x = 0; rect.y = (1.0f - scaleheight) / 2.0f; camera.rect = rect; } Its look like this on my mobile phone (portrait): and on landscape mode:

• How to use correctly the comments in C/++

  - by Lucio

  I'm learning to program in C and in my stage, the best form to use correctly the comments is writing good comments from the beginning. As the comments are not just for that one understands better the code but others too, I want to know the views of all of you to reach a consensus. So what I want is that the most experienced users edit the following code as you please. (If it's unnecessary, delete it; If it's wrong, correct it; If needed, add more) Thus there'll be multiple answers with different syntax and the responses with the most votes will be taken as referring when commenting. The code to copy, paste and edit to your pleasure is: (And I remark again, just import the comments, not the code) /* This programs find 1 number in 1 file. The file is binary type and has integers in series. The number is integer type and it's entered from the keyboard. When finished the program, a poster will show the results: Saying if the number is in the file or not. */ #include <stdio.h> //FUNCTION 1 //Open file 'path' and closes it. void openf(char path[]) { int num; //Read from Keyboard a Number and it save it into 'num' var printf("Ready for read number.\n\nNumber --> "); fflush(stdin); scanf("%d",&num); //Open file 'path' in READ mode FILE *fvar; fvar=fopen(path,"rb"); //IF error happens when open file, exit of function if (fvar==NULL) { printf("ERROR while open file %s in read mode.",path); exit(1); } /*Verify the result of 'funct' function IF TRUE, 'num' it's in the file*/ if (funct(path,fvar,num)) printf("The number %d it is in the file %s.",num,path); else printf("The number %d it is not in the file %s.",num,path); fclose(fvar); } /*FUNCTION 2 It is a recursive function. Reads number by number until the file is empty or the number is found. Parameters received: 'path' -> Directory file 'fvar' -> Pointer file 'num' -> Number to compare */ int funct(char path[],FILE *fvar,int num) { int compare; //FALSE condition when the pointer reaches the end if (fread(&compare,sizeof(int),1,fvar)>0) /*TRUE condition when the number readed is iqual that 'num' ELSE will go to the function itself*/ if (compare!=num) funct(path,fvar,num); else return 1; else return 0; } int main(int argc, char **argv) { char path[30]="file.bin"; //Direction of the file to process openf(path); //Function with algorithm return 0; }
