  • Oracle Social Network Developer Challenge: Bezzotech

    - by Kellsey Ruppel
    Originally posted by Jake Kuramoto on The Apps Lab blog. I’ve covered all the entries we had for the Oracle Social Network Developer Challenge, the winners, Dimitri and Martin, HarQen, TEAM Informatics and John Sim from Fishbowl Solutions, and today, I’m giving you bonus coverage. Friend of the ‘Lab, Bex Huff (@bex) from Bezzotech (@bezzotech), had an interesting OpenWorld. He rebounded from an allergic reaction to finish his entry, Honey Badger, only to have his other OpenWorld commitments make him unable to present his work. Still, he did a bunch of work, and I want to make sure everyone knows about the Honey Badger. If you’re wondering about the name, it’s a meme; “honey badger don’t care.” Bex tackled a common problem with social tools by adding game mechanics to create an incentive for people to keep their profiles updated. He used a Hot-or-Not style comparison app that poses expertise questions and awards a badge to the winner. Questions are based on whatever attributes the business wants to emphasize. The goal is to find the mavens in an organization, give them praise and recognition, ideally creating incentive for everyone to raise their games. In his own words: There is a real information quality problem in social networks. In last year’s keynote, Larry Elison demonstrated how to use the social network to track down resources that have the skill sets needed for specific projects. But how well would that work in real life? People usually update that information with the basic profile information, but they rarely update their profiles with latest news items, projects, customers, or skills. It’s a pain. Or, put another way, when was the last time you updated your LinkedIn profile? Enter the Honey Badger! This is a example of a comparator app that gamifies the way people keep their profiles updated, which ensures higher quality data in the social network. An administrator comes up with a series of important questions: Who is a better communicator? Who is a better Java programmer? Who is a better team player? And people would have a space in their profile to give a justification as to why they have these skills. The second part of the app is the comparator. It randomly shows two people, their names, and their justification for why they have these skills. You will click on one of them to “vote” for them, then on the next page you will see the results from the previous match, and get 2 new people to vote on. Anybody with a winning score wins a “Honey Badge” to be displayed on their profile page, which proudly states that their peers agree that this person has those skills. Once a badge is won, it will be jealously guarded. The longer your go without updating your profile, the more likely it is that you will lose your badge. This “loss aversion” is well known in psychology, and is a strong incentive for people to keep their profiles up to date. If a user sees their rank drop from 90% to 60%, they will find the time to update their justification! Unfortunately, during the hackathon we were not allowed to modify the schema to allow for additional fields such as “justification.” So this hack is limited to just the one basic question: who is the bigger Honey Badger? Here are some shots of the Honey Badger application: #gallery-1 { margin: auto; } #gallery-1 .gallery-item { float: left; margin-top: 10px; text-align: center; width: 33%; } #gallery-1 img { border: 2px solid #cfcfcf; } #gallery-1 .gallery-caption { margin-left: 0; } Thanks to Bex and everyone for participating in our challenge. Despite very little time to promote this event, we had a great turnout and creative and useful entries. The amount of work required to put together these final entries was significant, especially during a conference, and the judges and all of us involved were impressed at how much work everyone was able to do. Congrats to everyone, pat yourselves on the back. Stay tuned if you’re interested in challenges like these. We’ll likely be running similar events in the not-so-distant future.

  • Monitoring your WCF Web Apis with AppFabric

    - by cibrax
    The other day, Ron Jacobs made public a template in the Visual Studio Gallery for enabling monitoring capabilities to any existing WCF Http service hosted in Windows AppFabric. I thought it would be a cool idea to reuse some of that for doing the same thing on the new WCF Web Http stack. Windows AppFabric provides a dashboard that you can use to dig into some metrics about the services usage, such as number of calls, errors or information about different events during a service call. Those events not only include information about the WCF pipeline, but also custom events that any developer can inject and make sense for troubleshooting issues.      This monitoring capabilities can be enabled on any specific IIS virtual directory by using the AppFabric configuration tool or adding the following configuration sections to your existing web app, <system.serviceModel> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> <diagnostics etwProviderId="3e99c707-3503-4f33-a62d-2289dfa40d41"> <endToEndTracing propagateActivity="true" messageFlowTracing="true" /> </diagnostics> <behaviors> <serviceBehaviors> <behavior name=""> <etwTracking profileName="EndToEndMonitoring Tracking Profile" /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel>   <microsoft.applicationServer> <monitoring> <default enabled="true" connectionStringName="ApplicationServerMonitoringConnectionString" monitoringLevel="EndToEndMonitoring" /> </monitoring> </microsoft.applicationServer> Bad news is that none of the configuration above can be easily set on code by using the new configuration model for WCF Web stack.  A good thing is that you easily disable it in the configuration when you no longer need it, and also uses ETW, a general-purpose and high-speed tracing facility provided by the operating system (it’s part of the windows kernel). By adding that configuration section, AppFabric will start monitoring your service automatically and providing some basic event information about the service calls. You need some custom code for injecting custom events in the monitoring data. What I did here is to copy and refactor the “WCFUserEventProvider” class provided as sample in the Ron’s template to make it more TDD friendly when using IoC. I created a simple interface “ILogger” that any service (or resource) can use to inject custom events or monitoring information in the AppFabric database. public interface ILogger { bool WriteError(string name, string format, params object[] args); bool WriteWarning(string name, string format, params object[] args); bool WriteInformation(string name, string format, params object[] args); } The “WCFUserEventProvider” class implements this interface by making possible to send the events to the AppFabric monitoring database. The service or resource implementation can receive an “ILogger” as part of the constructor. [ServiceContract] [Export] public class OrderResource { IOrderRepository repository; ILogger logger;   [ImportingConstructor] public OrderResource(IOrderRepository repository, ILogger logger) { this.repository = repository; this.logger = logger; }   [WebGet(UriTemplate = "{id}")] public Order Get(string id, HttpResponseMessage response) { var order = this.repository.All.FirstOrDefault(o => o.OrderId == int.Parse(id, CultureInfo.InvariantCulture)); if (order == null) { response.StatusCode = HttpStatusCode.NotFound; response.Content = new StringContent("Order not found"); }   this.logger.WriteInformation("Order Requested", "Order Id {0}", id);   return order; } } The example above uses “MEF” as IoC for injecting a repository and the logger implementation into the service. You can also see how the logger is used to write an information event in the monitoring database. The following image illustrates how the custom event is injected and the information becomes available for any user in the dashboard. An issue that you might run into and I hope the WCF and AppFabric teams fixed soon is that any WCF service that uses friendly URLs with ASP.NET routing does not get listed as a available service in the WCF services tab in the AppFabric console. The complete example is available to download from here.

  • NoSQL Java API for MySQL Cluster: Questions & Answers

    - by Mat Keep
    The MySQL Cluster engineering team recently ran a live webinar, available now on-demand demonstrating the ClusterJ and ClusterJPA NoSQL APIs for MySQL Cluster, and how these can be used in building real-time, high scale Java-based services that require continuous availability. Attendees asked a number of great questions during the webinar, and I thought it would be useful to share those here, so others are also able to learn more about the Java NoSQL APIs. First, a little bit about why we developed these APIs and why they are interesting to Java developers. ClusterJ and Cluster JPA ClusterJ is a Java interface to MySQL Cluster that provides either a static or dynamic domain object model, similar to the data model used by JDO, JPA, and Hibernate. A simple API gives users extremely high performance for common operations: insert, delete, update, and query. ClusterJPA works with ClusterJ to extend functionality, including - Persistent classes - Relationships - Joins in queries - Lazy loading - Table and index creation from object model By eliminating data transformations via SQL, users get lower data access latency and higher throughput. In addition, Java developers have a more natural programming method to directly manage their data, with a complete, feature-rich solution for Object/Relational Mapping. As a result, the development of Java applications is simplified with faster development cycles resulting in accelerated time to market for new services. MySQL Cluster offers multiple NoSQL APIs alongside Java: - Memcached for a persistent, high performance, write-scalable Key/Value store, - HTTP/REST via an Apache module - C++ via the NDB API for the lowest absolute latency. Developers can use SQL as well as NoSQL APIs for access to the same data set via multiple query patterns – from simple Primary Key lookups or inserts to complex cross-shard JOINs using Adaptive Query Localization Marrying NoSQL and SQL access to an ACID-compliant database offers developers a number of benefits. MySQL Cluster’s distributed, shared-nothing architecture with auto-sharding and real time performance makes it a great fit for workloads requiring high volume OLTP. Users also get the added flexibility of being able to run real-time analytics across the same OLTP data set for real-time business insight. OK – hopefully you now have a better idea of why ClusterJ and JPA are available. Now, for the Q&A. Q & A Q. Why would I use Connector/J vs. ClusterJ? A. Partly it's a question of whether you prefer to work with SQL (Connector/J) or objects (ClusterJ). Performance of ClusterJ will be better as there is no need to pass through the MySQL Server. A ClusterJ operation can only act on a single table (e.g. no joins) - ClusterJPA extends that capability Q. Can I mix different APIs (ie ClusterJ, Connector/J) in our application for different query types? A. Yes. You can mix and match all of the API types, SQL, JDBC, ODBC, ClusterJ, Memcached, REST, C++. They all access the exact same data in the data nodes. Update through one API and new data is instantly visible to all of the others. Q. How many TCP connections would a SessionFactory instance create for a cluster of 8 data nodes? A. SessionFactory has a connection to the mgmd (management node) but otherwise is just a vehicle to create Sessions. Without using connection pooling, a SessionFactory will have one connection open with each data node. Using optional connection pooling allows multiple connections from the SessionFactory to increase throughput. Q. Can you give details of how Cluster J optimizes sharding to enhance performance of distributed query processing? A. Each data node in a cluster runs a Transaction Coordinator (TC), which begins and ends the transaction, but also serves as a resource to operate on the result rows. While an API node (such as a ClusterJ process) can send queries to any TC/data node, there are performance gains if the TC is where most of the result data is stored. ClusterJ computes the shard (partition) key to choose the data node where the row resides as the TC. Q. What happens if we perform two primary key lookups within the same transaction? Are they sent to the data node in one transaction? A. ClusterJ will send identical PK lookups to the same data node. Q. How is distributed query processing handled by MySQL Cluster ? A. If the data is split between data nodes then all of the information will be transparently combined and passed back to the application. The session will connect to a data node - typically by hashing the primary key - which then interacts with its neighboring nodes to collect the data needed to fulfil the query. Q. Can I use Foreign Keys with MySQL Cluster A. Support for Foreign Keys is included in the MySQL Cluster 7.3 Early Access release Summary The NoSQL Java APIs are packaged with MySQL Cluster, available for download here so feel free to take them for a spin today!

  • SSAS Maestro Training in July 2012 #ssasmaestro #ssas

    - by Marco Russo (SQLBI)
    A few hours ago Chris Webb blogged about SSAS Maestro and I’d like to propagate the news, adding also some background info. SSAS Maestro is the premier certification on Analysis Services that selects the best experts in Analysis Services around the world. In 2011 Microsoft organized two rounds of training/exams for SSAS Maestros and up to now only 11 people from the first wave have been announced – around 10% of attendees of the course! In the next few days the new Maestros from the second round should be announced and this long process is caused by many factors that I’m going to explain. First, the course is just a step in the process. Before the course you receive a list of topics to study, including the slides of the course. During the course, students receive a lot of information that might not have been included in the slides and the best part of the course is class interaction. Students are expected to bring their experience to the table and comparing case studies, experiences and having long debates is an important part of the learning process. And it is also a part of the evaluation: good questions might be also more important than good answers! Finally, after the course, students have their homework and this may require one or two months to be completed. After that, a long (very long) evaluation process begins, taking into account homework, labs, participation… And for this reason the final evaluation may arrive months later after the course. We are going to improve and shorten this process with the next courses. The first wave of SSAS Maestro had been made by invitation only and now the program is opening, requiring a fee to participate in order to cover the cost of preparation, training and exam. The number of attendees will be limited and candidates will have to send their CV in order to be admitted to the course. Only experienced Analysis Services developers will be able to participate to this challenging program. So why you should do that? Well, only 10% of students passed the exam until now. So if you need 100% guarantee to pass the exam, you need to study a lot, before, during and after the course. But the course by itself is a precious opportunity to share experience, create networking and learn mission-critical enterprise-level best practices that it’s hard to find written on books. Oh, well, many existing white papers are a required reading *before* the course! The course is now 5 days long, and every day can be *very* long. We’ll have lectures and discussions in the morning and labs in the afternoon/evening. Plus some more lectures in one or two afternoons. A heavy part of the course is about performance optimization, capacity planning, monitoring. This edition will introduce also Tabular models, and don’t expect something you might find in the SSAS Tabular Workshop – only performance, scalability monitoring and optimization will be covered, knowing Analysis Services is a requirement just to be accepted! I and Chris Webb will be the teachers for this edition. The course is expensive. Applying for SSAS Maestro will cost around 7000€ plus taxes (reduced to 5000€ for students of a previous SSAS Maestro edition). And you will be locked in a training room for the large part of the week. So why you should do that? Well, as I said, this is a challenging course. You will not find the time to check your email – the content is just too much interesting to think you can be distracted by something else. Another good reason is that this course will take place in Italy. Well, the course will take place in the brand new Microsoft Innovation Campus, but in general we’ll be able to provide you hints to get great food and, if you are willing to attach one week-end to your trip, there are plenty of places to visit (and I’m not talking about the classic Rome-Florence-Venice) – you might really need to relax after such a week! Finally, the marking process after the course will be faster – we’d like to complete the evaluation within three months after the course, considering that 1-2 months might be required to complete the homework. If at this point you are not scared: registration will open in mid-April, but you can already write to [email protected] sending your CV/resume and a short description of your level of SSAS knowledge and experience. The selection process will start early and you may want to put your admission form on top of the FIFO queue!

  • Rip and Convert DVD’s to an ISO Image

    - by Mysticgeek
    If you own a lot of DVD’s, you might want to convert them to an ISO image for backup and easily playing them on your media center. Today we take a look at ripping your discs using DVDFab, then using ImgBurn to create an ISO image of the ripped DVD files. Rip DVD with DVDFab6 DVDFab will remove copy protection and rip the DVD files for free. Other components in the suite require you to purchase a license after the 30 day trial, but you’ll still be able to rip DVD’s after the trial. Install DVDFab by accepting the defaults (link below)…a system restart is required to complete the install process. The first time you run it, a welcome screen is displayed. If you don’t want to see it again check the box Do not show again, then Start DVDFab.  Pop the DVD in your drive and click Next. Now select your region and check Do not show again, then OK. It will then open the DVD and begin to scan it. Under DVD to DVD you can select either Full Disc or Main Movie depending on what you want to rip. If you want to burn the DVD to a disc after it’s created select the Full Disc option. Now click the Start button to begin the ripping process. After the ripping process has completed, you’ll get a message telling you it’s waiting for you to put in a blank DVD. Since we aren’t burning the disc, just cancel the message. Click Finish and close out of DVDFab or just minimize it if you’re going to keep using it to rip another DVD. By default the temporary directory is in My Documents \ DVDFab \ Temp…however you can change it in settings. If you go to the Temp directory you’ll see the DVD files listed there… Convert Files to ISO with ImgBurn Now that we have the files ripped from the DVD, we need to convert them to an ISO image using ImgBurn (link below). Open it up and from the main menu click on Create image file from files/folders. Click on the folder icon to browse to the location of the ripped DVD files. Browse to the DVDFab temp directory and the VIDEO_TS folder for the source and click Ok. Then choose a destination directory, give the ISO a name, and click Save. In this case we ripped the Unbreakable DVD, so named it that.   So now in ImgBurn you have the source being the ripped DVD files, and the destination for the ISO…then click the Build button. If you don’t create a volume label, ImgBurn is kind enough to create on for you. If everything looks correct, click Ok. Now wait while ImgBurn goes through the process of converting the ripped DVD files to an ISO image. The process has successfully completed. The ISO image of the DVD will be in the output directory you selected earlier. Now you can burn the ISO image to a blank DVD or store it on an external hard drive for safe keeping. When you’re done, you’ll probably want to go into the temp DVDFab folder and delete the VOB and other files in the Video_TS folder as they will take up a lot of space on your hard drive.   Conclusion Although this method requires two programs to make an ISO out of a DVD, it’s extremely quick. When burning DVD’s of various lengths, it took less than 30 minutes to get the final ISO. Now, you’ll have your DVD movies backed up in case something were to happen to the discs and are no longer playable. If you use Windows Media Center to watch your movies, check out our article on how to automatically mount and view ISO files in Windows 7 Media Center. With DVDFab, you get a 30 day fully functional trial for all of its features. You’ll still be able rip DVD’s even after the 30 day trial has ended. The more we’ve been using DVDFab, the more impressed we are with its capabilities, so after the 30 day trial you should consider purchasing a license. We will have a full review of the of it to share with you soon.  Download DVDFab Download ImgBurn Similar Articles Productive Geek Tips How To Rip DVDs with VLCCalculate with Qalculate on LinuxConvert a Row to a Column in Excel the Easy WayEnjoy Quick & Easy Unit Conversion with Convert for WindowsConvert Older Excel Documents to Excel 2007 Format TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 PCmover Professional Beware Hover Kitties Test Drive Mobile Phones Online With TryPhone Ben & Jerry’s Free Cone Day, 3/23/10 New Stinger from McAfee Helps Remove ‘FakeAlert’ Threats Google Apps Marketplace: Tools & Services For Google Apps Users Get News Quick and Precise With Newser

  • Some notes on Reflector 7

    - by CliveT
    Both Bart and I have blogged about some of the changes that we (and other members of the team) have made to .NET Reflector for version 7, including the new tabbed browsing model, the inclusion of Jason Haley's PowerCommands add-in and some improvements to decompilation such as handling iterator blocks. The intention of this blog post is to cover all of the main new features in one place, and to describe the three new editions of .NET Reflector 7. If you'd simply like to try out the latest version of the beta for yourself you can do so here. Three new editions .NET Reflector 7 will come in three new editions: .NET Reflector .NET Reflector VS .NET Reflector VSPro The first edition is just the standalone Windows application. The latter two editions include the Windows application, but also add the power of Reflector into Visual Studio so that you can save time switching tools and quickly get to the bottom of a debugging issue that involves third-party code. Let's take a look at some of the new features in each edition. Tabbed browsing .NET Reflector now has a tabbed browsing model, in which the individual tabs have independent histories. You can open a new tab to view the selected object by using CTRL+CLICK. I've found this really useful when I'm investigating a particular piece of code but then want to focus on some other methods that I find along the way. For version 7, we wanted to implement the basic idea of tabs to see whether it is something that users will find helpful. If it is something that enhances productivity, we will add more tab-based features in a future version. PowerCommands add-in We have also included Jason Haley's PowerCommands add-in as part of version 7. This add-in provides a number of useful commands, including support for opening .xap files and extracting the constituent assemblies, and a query editor that allows C# queries to be written and executed against the Reflector object model . All of the PowerCommands features can be turned on from the options menu. We will be really interested to see what people are finding useful for further integration into the main tool in the future. My personal favourite part of the PowerCommands add-in is the query editor. You can set up as many of your own queries as you like, but we provide 25 to get you started. These do useful things like listing all extension methods in a given assembly, and displaying other lower-level information, such as the number of times that a given method uses the box IL instruction. These queries can be extracted and then executed from the 'Run Query' context menu within the assembly explorer. Moreover, the queries can be loaded, modified, and saved using the built-in editor, allowing very specific user customization and sharing of queries. The PowerCommands add-in contains many other useful utilities. For example, you can open an item using an external application, work with enumeration bit flags, or generate assembly binding redirect files. You can see Bart's earlier post for a more complete list. .NET Reflector VS .NET Reflector VS adds a brand new Reflector object browser into Visual Studio to save you time opening .NET Reflector separately and browsing for an object. A 'Decompile and Explore' option is also added to the context menu of references in the Solution Explorer, so you don't need to leave Visual Studio to look through decompiled code. We've also added some simple navigation features to allow you to move through the decompiled code as quickly and easily as you can in .NET Reflector. When this is selected, the add-in decompiles the given assembly, Once the decompilation has finished, a clone of the Reflector assembly explorer can be used inside Visual Studio. When Reflector generates the source code, it records the location information. You can therefore navigate from the source file to other decompiled source using the 'Go To Definition' context menu item. This then takes you to the definition in another decompiled assembly. .NET Reflector VSPro .NET Reflector VSPro builds on the features in .NET Reflector VS to add the ability to debug any source code you decompile. When you decompile with .NET Reflector VSPro, a matching .pdb is generated, so you can use Visual Studio to debug the source code as if it were part of the project. You can now use all the standard debugging techniques that you are used to in the Visual Studio debugger, and step through decompiled code as if it were your own. Again, you can select assemblies for decompilation. They are then decompiled. And then you can debug as if they were one of your own source code files. The future of .NET Reflector As I have mentioned throughout this post, most of the new features in version 7 are exploratory steps and we will be watching feedback closely. Although we don't want to speculate now about any other new features or bugs that will or won't be fixed in the next few versions of .NET Reflector, Bart has mentioned in a previous post that there are lots of improvements we intend to make. We plan to do this with great care and without taking anything away from the simplicity of the core product. User experience is something that we pride ourselves on at Red Gate, and it is clear that Reflector is still a long way off our usual standards. We plan for the next few versions of Reflector to be worked on by some of our top usability specialists who have been involved with our other market-leading products such as the ANTS Profilers and SQL Compare. I re-iterate the need for the really great simple mode in .NET Reflector to remain intact regardless of any other improvements we are planning to make. I really hope that you enjoy using some of the new features in version 7 and that Reflector continues to be your favourite .NET development tool for a long time to come.

  • Top Reasons You Need A User Engagement Platform

    - by Michael Snow
    Guest post by: Amit Sircar, Senior Sales Consultant, Oracle Deliver complex enterprise functionality through a simple intuitive and unified User Interface (UI) The modern enterprise contains a wide range of applications that are used to manage the business and drive competitive advantages. Organizations respond by creating a complex structure that results in a functional and management grouping of users. Each of these groups of users requires access to multiple applications and information sources in order to perform their job functions. This leads to the lack of a unified view of enterprise information, inconsistent user interfaces and disjointed security. To be effective, portals must be designed from the end-user perspective, enabling the user to accomplish as many tasks as possible while visiting the fewest number of portals. This requires rethinking the way that portals are built, moving from a functional business unit perspective to a user-focused, process-oriented point of view. Oracle WebCenter provides the Common User Experience Architecture that allows organizations to seamlessly present a unified view of enterprise information tailored to a particular user’s role and preferences. This architecture provides the best practices, design patterns and delivery mechanism for myriad services, applications, and data sources.  In order to serve as a primary system of access, Oracle WebCenter also provides access to unstructured content and to other users via integrated search, service-oriented artifacts, content management, and collaboration tools. Provide a modern and engaging experience without modifying the core business application Web 2.0 technologies such as blogs, wikis, forums or social media sites are having a profound impact in the public internet.  These technologies can be leveraged by enterprises to add significant value to the business. Organizations need to integrate these technologies directly into their business applications while continuing to meet their security and governance needs. To deliver richer connections and become a more agile and intelligent business, WebCenter provides an enterprise portal platform that contains pre-integrated, standards-based Enterprise 2.0 services. These Enterprise 2.0 services can be easily accessed, integrated and utilized by users. By giving users the ability to use and integrate Enterprise 2.0 services such as tags, links, wikis, activities, blogs or social networking directly with their portals and applications, they are empowered to make richer connections, optimize their productivity, and ultimately increase the value of their applications. Foster a collaborative experience The organizational workplace has undergone a major change in the last decade. With increasing globalization and a distributed workforce, project teams may be physically separated by large distances. Online collaboration technologies are becoming a critical resource to enable virtual teams to share information and work together effectively. Oracle WebCenter delivers dynamic business communities with rich Services to empower teams to quickly and efficiently manage their information, applications, projects, and people without requiring IT assistance. It brings together the latest technology around Enterprise 2.0 and social computing, communities, personal productivity, and ad-hoc team interactions without any development effort. It enables the sharing and collaboration on team content, focusing an organization’s valuable resources on solving business problems, tapping into new ideas, and reducing time-to-market. Mobile Support The traditional workplace dynamics that required employees to access their work applications from their desktops have undergone a fundamental shift. Employees were used to primarily working from company offices and utilized an IT-issued computer for performing their job functions. With the introduction of flexible work hours and the growth of remote workers, more and more employees need the ability to remain productive even when they do not have access to a computer via the use of tablets and smartphones.  In addition, customers and citizens have come to expect 24x7 access to resources and websites from wherever they are located. Tablets and smartphones have empowered everyone to quickly access services they need anytime and from any place.  WebCenter provides out of the box capabilities to deliver the mobile experience in a seamless manner. Seeded device profiles and toolkits within WebCenter can be used to render the same web pages into multiple target devices such iPads, iPhones and android devices. Web designers can preview the portal using the built in simulator, make necessary updates and then deploy their UI design for the targeted device. Conclusion The competitive economy and resource constraints facing organizations today require them to find ways to make their applications, portals and Web sites more agile and intelligent and their knowledge workers more productive no matter where they are located. Organizations need to provide faster access to relevant information and resources, enhance existing applications and business processes with rich Enterprise 2.0 services, and seamlessly deliver content to mobile platforms. Oracle WebCenter successfully meets these challenges by providing the modern user experience platform for the enterprise and the Web.

  • Announcing the New Windows Azure Web Sites Shared Scaling Tier

    - by Clint Edmonson
    Windows Azure Web Sites has added a new pricing tier that will solve the #1 blocker for the web development community. The shared tier now supports custom domain names mapped to shared-instance web sites. This post will outline the plan changes and elaborate on how the new pricing model makes Windows Azure Web Sites an even richer option for web development shops of all sizes. Free Shared Reserved # of Sites 10 100 100 Egress 165MB/Day 5GB/Month Included 5GB/Month Included Storage 1GB 1GB 10GB Throttling CPU/Memory/Egress CPU/Memory Unlimited Price Free $.02/hr per site, per instance $.08/hr per core Setting the Stage In June, we released the first public preview of Windows Azure Web Sites, which gave web developers a great platform on which to get web sites running using their web development framework of choice. PHP, Node.js, classic ASP, and ASP.NET developers can all utilize the Windows Azure platform to create and launch their web sites. Likewise, these developers have a series of data storage options using Windows Azure SQL Databases, MySQL, or Windows Azure Storage. The Windows Azure Web Sites free offer enabled startups to get their site up and running on Windows Azure with a minimal investment, and with multiple deployment and continuous integration features such as Git, Team Foundation Services, FTP, and Web Deploy.  The response to the Windows Azure Web Sites offer has been overwhelmingly positive. Since the addition of the service on June 12th, tens of thousands of web sites have been deployed to Windows Azure and the volume of adoption is increasing every week. Preview Feedback In spite of the growth and success of the product, the community has had questions about features lacking in the free preview offer. The main question web developers asked regarding Windows Azure Web Sites relates to the lack of the free offer’s support for domain name mapping. During the preview launch period, customer feedback made it obvious that the lack of domain name mapping support was an area of concern. We’re happy to announce that this #1 request has been delivered as a feature of the new shared plan. New Shared Tier Portal Features In the screen shot below, the “Scale” tab in the portal shows the new tiers – Free, Shared, and Reserved – and gives the user the ability to quickly move any of their free web sites into the shared tier. With a single mouse-click, the user can move their site into the shared tier. Once a site has been moved into the shared tier, a new Manage Domains button appears in the bottom action bar of the Windows Azure Portal giving site owners the ability to manage their domain names for a shared site. This button brings up the domain-management dialog, which can be used to enter in a specific domain name that will be mapped to the Windows Azure Web Site. Shared Tier Benefits Startups and large web agencies will both benefit from this plan change. Here are a few examples of scenarios which fit the new pricing model: Startups no longer have to select the reserved plan to map domain names to their sites. Instead, they can use the free option to develop their sites and choose on a site-by-site basis which sites they elect to move into the shared plan, paying only for the sites that are finished and ready to be domain-mapped Agencies who manage dozens of sites will realize a lower cost of ownership over the long term by moving their sites into reserved mode. Once multi-site companies reach a certain price point in the shared tier, it is much more cost-effective to move sites to a reserved tier.  Long-term, it’s easy to see how the new Windows Azure Web Sites shared pricing tier makes Windows Azure Web Sites it a great choice for both startups and agency customers, as it enables rapid growth and upgrades while keeping the cost to a minimum. Large agencies will be able to have all of their sites in their own instances, and startups will have the capability to scale up to multiple-shared instances for minimal cost and eventually move to reserved instances without worrying about the need to incur continually additional costs. Customers can feel confident they have the power of the Microsoft Windows Azure brand and our world-class support, at prices competitive in the market. Plus, in addition to realizing the cost savings, they’ll have the whole family of Windows Azure features available. Continuous Deployment from GitHub and CodePlex Along with this new announcement are two other exciting new features. I’m proud to announce that web developers can now publish their web sites directly from CodePlex or GitHub.com repositories. Once connections are established between these services and your web sites, Windows Azure will automatically be notified every time a check-in occurs. This will then trigger Windows Azure to pull the source and compile/deploy the new version of your app to your web site automatically. Walk-through videos on how to perform these functions are below: Publishing to an Azure Web Site from CodePlex Publishing to an Azure Web Site from GitHub.com These changes, as well as the enhancements to the reserved plan model, make Windows Azure Web Sites a truly competitive hosting option. It’s never been easier or cheaper for a web developer to get up and running. Check out the free Windows Azure web site offering and see for yourself.

  • Windows Azure Recipe: Enterprise LOBs

    - by Clint Edmonson
    Enterprises are more and more dependent on their specialized internal Line of Business (LOB) applications than ever before. Naturally, the more software they leverage on-premises, the more infrastructure they need manage. It’s frequently the case that our customers simply can’t scale up their hardware purchases and operational staff as fast as internal demand for software requires. The result is that getting new or enhanced applications in the hands of business users becomes slower and more expensive every day. Being able to quickly deliver applications in a rapidly changing business environment while maintaining high standards of corporate security is a challenge that can be met right now by moving enterprise LOBs out into the cloud and leveraging Azure’s Access Control services. In fact, we’re seeing many of our customers (both large and small) see huge benefits from moving their web based business applications such as corporate help desks, expense tracking, travel portals, timesheets, and more to Windows Azure. Drivers Cost Reduction Time to market Security Solution Here’s a sketch of how many Windows Azure Enterprise LOBs are being architected and deployed: Ingredients Web Role – this will host the core of the application. Each web role is a virtual machine hosting an application written in ASP.NET (or optionally php, or node.js). The number of web roles can be scaled up or down as needed to handle peak and non-peak traffic loads. Many Java based applications are also being deployed to Windows Azure with a little more effort. Database – every modern web application needs to store data. SQL Azure databases look and act exactly like their on-premise siblings but are fault tolerant and have data redundancy built in. Access Control – this service is necessary to establish federated identity between the cloud hosted application and an enterprise’s corporate network. It works in conjunction with a secure token service (STS) that is hosted on-premises to establish the corporate user’s identity and credentials. The source code for an on-premises STS is provided in the Windows Azure training kit and merely needs to be customized for the corporate environment and published on a publicly accessible corporate web site. Once set up, corporate users see a near seamless single sign-on experience. Reporting – businesses live and die by their reports and SQL Azure Reporting, based on SQL Server Reporting 2008 R2, can serve up reports with tables, charts, maps, gauges, and more. These reports can be accessed from the Windows Azure Portal, through a web browser, or directly from applications. Service Bus (optional) – if deep integration with other applications and systems is needed, the service bus is the answer. It enables secure service layer communication between applications hosted behind firewalls in on-premises or partner datacenters and applications hosted inside Windows Azure. The Service Bus provides the ability to securely expose just the information and services that are necessary to create a simpler, more secure architecture than opening up a full blown VPN. Data Sync (optional) – in cases where the data stored in the cloud needs to be shared internally, establishing a secure one-way or two-way data-sync connection between the on-premises and off-premises databases is a perfect option. It can be very granular, allowing us to specify exactly what tables and columns to synchronize, setup filters to sync only a subset of rows, set the conflict resolution policy for two-way sync, and specify how frequently data should be synchronized Training Labs These links point to online Windows Azure training labs where you can learn more about the individual ingredients described above. (Note: The entire Windows Azure Training Kit can also be downloaded for offline use.) Windows Azure (16 labs) Windows Azure is an internet-scale cloud computing and services platform hosted in Microsoft data centers, which provides an operating system and a set of developer services which can be used individually or together. It gives developers the choice to build web applications; applications running on connected devices, PCs, or servers; or hybrid solutions offering the best of both worlds. New or enhanced applications can be built using existing skills with the Visual Studio development environment and the .NET Framework. With its standards-based and interoperable approach, the services platform supports multiple internet protocols, including HTTP, REST, SOAP, and plain XML SQL Azure (7 labs) Microsoft SQL Azure delivers on the Microsoft Data Platform vision of extending the SQL Server capabilities to the cloud as web-based services, enabling you to store structured, semi-structured, and unstructured data. Windows Azure Services (9 labs) As applications collaborate across organizational boundaries, ensuring secure transactions across disparate security domains is crucial but difficult to implement. Windows Azure Services provides hosted authentication and access control using powerful, secure, standards-based infrastructure. See my Windows Azure Resource Guide for more guidance on how to get started, including links web portals, training kits, samples, and blogs related to Windows Azure.

  • Upcoming User Group Events in 2011

    - by john.orourke(at)oracle.com
    At a recent customer event, someone asked me if Oracle had any plans to re-create the Hyperion Solutions Conference.  Unfortunately the answer is no.  With so many different product lines it would be challenging and costly for Oracle to run separate user conferences for every product line, and it would create too many events for customers with multiple products to attend.  So Oracle Open World is the company's main event for showcasing what's new and what's coming across all product lines.  If customers find Oracle OpenWorld too overwhelming or if the timing is bad, there are a number of other conferences, which are run by Oracle user groups and include a number of sessions focused on Oracle Hyperion EPM and BI products.  Here's a sneak preview of what's coming up for conferences in 2011 where you can network with other Hyperion users and learn what's new and what's coming in our products. Alliance 2011:  This conference is run by the Oracle Higher Education User Group (HEUG).  It's being held March 27 - 30th in lovely Denver, Colorado.  (a great location and time for skiers!)  This event is targeted at customers in Higher Education and Public Sector organizations and is expecting to draw over 3,500 attendees.  There will be a number of sessions focusing on Oracle Hyperion EPM and BI products in the Budgeting track, as well as the Reporting & BI track.  This includes product-focused sessions delivered by Oracle and partners, as well as case studies delivered by customers.  Here's a link to the registration page where you can get more information: http://www.heug.org/p/cm/ld/fid=255 Collaborate 2011:  This conference is run by three different user groups;  OAUG, IOUG and Quest.  It's being held April 10 - 14th in sunny Orlando, Florida.  (yes, sunshine and warmth!)  This event is targeted to customers with Oracle E-Business Suite, PeopleSoft, JD Edwards, Hyperion, Primavera and other products and is expected to draw over 5,000 attendees.  You'll find a number of sessions focused on Oracle Hyperion EPM and BI products in the BI/Data Warehousing/EPM track.  This includes product-focused sessions delivered by Oracle, our partners, and customers as well as a number of customer case studies.  There will also be an exhibit area with a number of demo pods focused on EPM and BI products.  Here's a link to the conference web site where you can get more information: http://collaborate.oaug.org/ Also, please note that the OAUG has a Hyperion SIG that runs focused EPM/Hyperion events throughout the year.  Here's a link to their web site where you can get more information: http://hyperionsig.oaug.org/ Kscope 2011:  Formerly the Kaleidoscope conference, this one is run by the Oracle Developer Tools User Group (ODTUG).  This conference is being held June 26 - 30th in Long Beach, CA. (surf's up!)  Historically, this event has focused on Oracle Development tools, but over the past few years the EPM and BI content has grown with over 100 sessions planned this year.  So this event is becoming a great venue for existing Hyperion customers to learn about the latest developments with Oracle Essbase, Hyperion Planning, Hyperion Financial Management, Oracle BI and other products.   You'll also find hands-on workshops, product demonstrations as well as EPM and BI Symposiums run by Oracle Development staff.  Here's a link to the web site where you can get more details.  http://www.kscope11.com/biepm UKOUG Conference Series:  EPM and Hyperion 2011:  For Hyperion customers in the UK, the UKOUG has a Hyperion SIG that runs a focused conference for EPM and Hyperion products.  The 2011 event is planned for June in London.  Here's a link to the web site for this event where you can get more information: http://hyperion.ukoug.org/default.asp?p=8461 In addition to these conferences, you can also find Oracle EPM and BI content at regional user group meetings globally as well as Marketing events run by Oracle.  Check the events page at www.oracle.com for the details on upcoming Marketing and regional User Group events.  So while Oracle will not be trying to replicate the Hyperion Solutions conference, the good news is that there are a number of other events available where customers can find out what's new and what's coming with Oracle EPM and BI products.  And these events are running at different times of the year in different locations - so you can pick the event that makes the most sense for your company from a timing and location standpoint. I'll be delivering a number of sessions at the Alliance and Collaborate conferences and hope to see many of our loyal customers and partners at these events.  And there's always Oracle OpenWorld coming up in October, for which the planning has already started.  I look forward to seeing you in 2011.

  • How to create a PeopleCode Application Package/Application Class using PeopleTools Tables

    - by Andreea Vaduva
    This article describes how - in PeopleCode (Release PeopleTools 8.50) - to enable a grid without enabling each static column, using a dynamic Application Class. The goal is to disable the following grid with three columns “Effort Date”, ”Effort Amount” and “Charge Back” , when the Check Box “Finished with task” is selected , without referencing each static column; this PeopleCode could be used dynamically with any grid. If the check box “Finished with task” is cleared, the content of the grid columns is editable (and the buttons “+” and “-“ are available): So, you create an Application Package “CLASS_EXTENSIONS” that contains an Application Class “EWK_ROWSET”. This Application Class is defined with Class extends “ Rowset” and you add two news properties “Enabled” and “Visible”: After creating this Application Class, you use it in two PeopleCode Events : Rowinit and FieldChange : This code is very ‘simple’, you write only one command : ” &ERS2.Enabled = False” → and the entire grid is “Enabled”… and you can use this code with any Grid! So, the complete PeopleCode to create the Application Package is (with explanation in [….]) : ******Package CLASS_EXTENSIONS : [Name of the Package: CLASS_EXTENSIONS] --Beginning of the declaration part------------------------------------------------------------------------------ class EWK_ROWSET extends Rowset; [Definition Class EWK_ROWSET as a subclass of Class Rowset] method EWK_ROWSET(&RS As Rowset); [Constructor is the Method with the same name of the Class] property boolean Visible get set; property boolean Enabled get set; [Definition of the property “Enabled” in read/write] private [Before the word “private”, all the declarations are publics] method SetDisplay(&DisplaySW As boolean, &PropName As string, &ChildSW As boolean); instance boolean &EnSW; instance boolean &VisSW; instance Rowset &NextChildRS; instance Row &NextRow; instance Record &NextRec; instance Field &NextFld; instance integer &RowCnt, &RecCnt, &FldCnt, &ChildRSCnt; instance integer &i, &j, &k; instance CLASS_EXTENSIONS:EWK_ROWSET &ERSChild; [For recursion] Constant &VisibleProperty = "VISIBLE"; Constant &EnabledProperty = "ENABLED"; end-class; --End of the declaration part------------------------------------------------------------------------------ method EWK_ROWSET [The Constructor] /+ &RS as Rowset +/ %Super = &RS; end-method; get Enabled /+ Returns Boolean +/; Return &EnSW; end-get; set Enabled /+ &NewValue as Boolean +/; &EnSW = &NewValue; %This.InsertEnabled=&EnSW; %This.DeleteEnabled=&EnSW; %This.SetDisplay(&EnSW, &EnabledProperty, False); [This method is called when you set this property] end-set; get Visible /+ Returns Boolean +/; Return &VisSW; end-get; set Visible /+ &NewValue as Boolean +/; &VisSW = &NewValue; %This.SetDisplay(&VisSW, &VisibleProperty, False); end-set; method SetDisplay [The most important PeopleCode Method] /+ &DisplaySW as Boolean, +/ /+ &PropName as String, +/ /+ &ChildSW as Boolean +/ [Not used in our example] &RowCnt = %This.ActiveRowCount; &NextRow = %This.GetRow(1); [To know the structure of a line ] &RecCnt = &NextRow.RecordCount; For &i = 1 To &RowCnt [Loop for each Line] &NextRow = %This.GetRow(&i); For &j = 1 To &RecCnt [Loop for each Record] &NextRec = &NextRow.GetRecord(&j); &FldCnt = &NextRec.FieldCount; For &k = 1 To &FldCnt [Loop for each Field/Record] &NextFld = &NextRec.GetField(&k); Evaluate Upper(&PropName) When = &VisibleProperty &NextFld.Visible = &DisplaySW; Break; When = &EnabledProperty; &NextFld.Enabled = &DisplaySW; [Enable each Field/Record] Break; When-Other Error "Invalid display property; Must be either VISIBLE or ENABLED" End-Evaluate; End-For; End-For; If &ChildSW = True Then [If recursion] &ChildRSCnt = &NextRow.ChildCount; For &j = 1 To &ChildRSCnt [Loop for each Rowset child] &NextChildRS = &NextRow.GetRowset(&j); &ERSChild = create CLASS_EXTENSIONS:EWK_ROWSET(&NextChildRS); &ERSChild.SetDisplay(&DisplaySW, &PropName, &ChildSW); [For each Rowset child, call Method SetDisplay with the same parameters used with the Rowset parent] End-For; End-If; End-For; end-method; ******End of the Package CLASS_EXTENSIONS:[Name of the Package: CLASS_EXTENSIONS] About the Author: Pascal Thaler joined Oracle University in 2005 where he is a Senior Instructor.

  • Five Things Learned at the BSR Conference in San Francisco on Nov 2nd-4th

    - by Evelyn Neumayr
    The BSR Conference 2011—“Redefining Leadership”—held from Nov 2nd to Nov 4th in San Francisco, with Oracle as one of the main sponsors, saw senior business executives, civil society representatives, and other experts from around the world gathering to share strategies and insights on the future of sustainability. The general conference sessions kicked off on November 2nd with a plenary address by former U.S. Vice President Al Gore. Other sessions were presented by CEOs of the caliber of Carl Bass (Autodesk), Brian Dunn (Best Buy), Carlos Brito (Anheuser-Busch InBev) and Ofra Strauss (Strauss Group). Here are five key highlights from the conference: 1.      The main leadership challenge is integrating sustainability into core business functions and overcoming short-termism. The “BSR GlobeScan State of Sustainable Business Poll 2011” - a survey of nearly 500 business leaders from 300 member companies - shows that 84% of respondents are optimistic that global businesses will embrace CSR/sustainability as part of their core strategies and operations in the next five years but consider integrating sustainability into their core business functions the key challenge. It is still difficult for many companies that are committed to the sustainability agenda to find investors that understand the long-term implications and as Al Gore said “Many companies are given the signal by the investors that it is the short term results that matter and that is a terribly debilitating force in the market.” 2.      Companies are required to address increasing compliance requirements and transparency in their supply chain, especially in relation with conflict minerals legislation and water management. The Dodd-Frank legislation, OECD guidelines, and the upcoming Securities and Exchange Commission (SEC) rules require companies to monitor upstream the sourcing of tin, tantalum, tungsten, and gold, but given the complexity of this issue companies need to collaborate and partner with peer companies in their industry as well as in other industries to understand how to address conflict minerals in their supply chains. The Institute of Public and Environmental Affairs’ (IPE) China Water Pollution Map enables the public to access thousands of environmental quality, discharge, and infraction records released by various government agencies. Empowered with this information, the public has the opportunity to place greater pressure on polluting companies to comply with environmental standards and create solutions to improve their performance. 3.      A new standard for reporting on supply chain greenhouse gas emissions is available. The New “Scope 3” Supply Chain Greenhouse Gas Inventory Standard, released on October 4th 2011, is the only international greenhouse gas emissions standard that accounts for the full lifecycle of a company’s products. It provides a framework for companies to account for indirect emissions outside of energy use, such as transportation, manufacturing, and distribution, and it incorporates both upstream and downstream impacts of a product. With key investors now listing supplier vulnerability to rising energy prices and disruptions of service as a key concern, greenhouse gas (GHG) management isn’t just for leading companies but a necessity for any business. 4.      Environmental, social, and corporate governance (ESG) reporting is becoming increasingly important to investors and other stakeholders. While European investors have traditionally driven the ESG agenda, U.S. investors are increasingly including ESG data in their analyses. This trend will likely increase as stakeholders continue to demand that an ESG lens be applied to their investments. Investors are increasingly looking to partner on sustainability, as they see the benefits of ESG providing significant returns on investment. 5.      Software companies are offering an increasing variety of solutions to help drive changes and measure performance internally, in supply chains, and across peer companies. The significant challenge is how to integrate different software systems to facilitate decision-making based on a holistic understanding of trade-offs. Jon Chorley, Chief Sustainability Officer and Vice President, Supply Chain Management Product Strategy at Oracle was a panelist in the “Trends in Sustainability Software” session and commented that, “How we think about our business decisions really comes down to how we think about cost. And as long as we don’t assign a cost to things that have an environmental impact or social impact, then we make decisions based on incomplete information. If we could include that in the process that determines ‘Is this product profitable? we would then have a much better decision.” For more information on BSR visit www.brs.org. You can also view highlights of the plenary session at http://www.bsr.org/en/bsr-conference/session-summaries/2011. Oracle is proud to be a sponsor of this BSR conference.

  • Java2Days 2012 Trip Report

    - by reza_rahman
    Java2Days 2012 was held in beautiful Sofia, Bulgaria on October 25-26. For those of you not familiar with it, this is the third installment of the premier Java conference for the Balkan region. It is an excellent effort by admirable husband and wife team Emo Abadjiev and Iva Abadjieva as well as the rest of the Java2Days team including Yoana Ivanova and Nadia Kostova. Thanks to their hard work, the conference continues to grow vigorously with almost a thousand enthusiastic, bright young people attending this year and no less than three tracks on Java, the Cloud and Mobile. The conference is a true gem in this region of the world and I am very proud to have been a part of it again, along with the other world class speakers the event rightfully attracts. It was my honor to present the first talk of the conference. It was a full-house session on Java EE 7 and 8 titled "JavaEE.Next(): Java EE 7, 8, and Beyond". The talk was primarily along the same lines as Arun Gupta's JavaOne 2012 technical keynote. I covered the changes in JMS 2, the Java API for WebSocket (JSR 356), the Java API for JSON Processing (JSON-P), JAX-RS 2, JCache, JPA 2.1, JTA 1.2, JSF 2.2, Java Batch, Bean Validation 1.1 and the rest of the APIs in Java EE 7. I also briefly talked about the possible contents of Java EE 8. My stretch goal was to gather some feedback on some open issues in the Java EE EG (more on that soon) but I ran out of time in the short format forty-five minute session. The talk was received well and I had some pretty good discussions afterwards. The slides for the talk are here: JavaEE.Next(): Java EE 7, 8, and Beyond from reza_rahman To my delight, the Java2Days folks were very interested in my domain-driven design/Java EE 6 talk (titled "Domain Driven Design with Java EE 6"). I've had this talk in my inventory for a long time now but it always gets overridden by less theoretical talks on APIs, tools, etc. The talk has three parts -- a brief overview of DDD theory, mapping DDD to Java EE and actual running DDD code in Java EE 6/GlassFish. For the demo, I converted the well-known DDD sample application (http://dddsample.sourceforge.net/) written mostly in Spring 2 and Hibernate 2 to Java EE 6. My eventual plan is to make the code available via a top level java.net project. Even despite the broad topic and time constraints, the talk went very well. It was a full house, the Q & A was excellent and one of the other speakers even told me they thought this was the best talk of the conference! The slides for the talk are here: Domain Driven Design with Java EE 6 from Reza Rahman The code examples are available here: https://blogs.oracle.com/reza/resource/dddsample.zip for now, as a simple zip file. Give me a shout if you would like to get it up and running. It was also a great honor to present the last session of the conference. It was a talk on the Java API for WebSocket/JSR 356 titled "Building HTML5/WebSocket Applications with JSR 356 and GlassFish". The talk is based on Danny Coward's JavaOne 2012 talk. The talk covers the basic of WebSocket, the JSR 356 API and a simple demo using Tyrus/GlassFish. The talk went very well and there were some very good questions afterwards. The slides for the talk are here: Building HTML5/WebSocket Applications with GlassFish and JSR 356 from Reza Rahman The code samples are available here: https://blogs.oracle.com/arungupta/resource/totd183-HelloWebSocket.zip. You'll need the latest promoted GlassFish 4 build to run the code. Give me a shout if you need help. Besides presenting my talks, I got to attend some great sessions on OSGi, HTML5, cloud, agile and Java 8. I got an invite to speak at the Macedonia JUG when possible. Victor Grazi of InfoQ wrote about my sessions and Java2Days here: http://www.infoq.com/news/2012/11/Java2DaysConference. Stoyan Rachev was very kind to blog about my sessions here: http://www.stoyanr.com/2012/11/java2days-2012-java-ee.html. I definitely enjoyed Java2Days 2012 and hope to be part of the conference next year!

  • Introducing jLight &ndash; Talking to the DOM using Silverlight and jQuery.

    - by Timmy Kokke
    Introduction With the recent news about Silverlight on the Windows Phone and all the great Out-Of-Browser features in the upcoming Silverlight 4 you almost forget Silverlight is a browser plugin. It most often runs in a web browser and often as a control. In many cases you need to communicate with the browser to get information about textboxes, events or details about the browser itself. To do this you can use JavaScript from Silverlight. Although Silverlight works the same on every browser, JavaScript does not and it won’t be long before problems arise. To overcome differences in browser I like to use jQuery. The only downside of doing this is that there’s a lot more code needed that you would normally use when you write jQuery in JavaScript. Lately, I had to catch changes is the browser scrollbar and act to the new position. I also had to move the scrollbar when the user dragged around in the Silverlight application. With jQuery it was peanuts to get and set the right attributes, but I found that I had to write a lot of code on Silverlight side.  With a few refactoring I had a separated out the plumbing into a new class and could call only a few methods on that to get the same thing done. The idea for jLight was born. jLight vs. jQuery The main purpose of jLight is to take the ease of use of jQuery and bring it into Silverlight for handling DOM interaction. For example, to change the text color of a DIV to red, in jQuery you would write: jQuery("div").css("color","red"); In jLight the same thing looks like so: jQuery.Select("div").Css("color","red");   Another example. To change the offset in of the last SPAN you could write this in jQuery : jQuery("span:last").offset({left : 10, top : 100});   In jLight this would do the same: jQuery.Select("span:last").Offset(new {left = 10, top = 100 });   Callbacks Nothing too special so far. To get the same thing done using the “normal” HtmlPage.Window.Eval, it wouldn’t require too much effort. But to wire up a handler for events from the browser it’s a whole different story. Normally you need to register ScriptMembers, ScriptableTypes or write some code in JavaScript. jLight takes care of the plumbing and provide you with an simple interface in the same way jQuery would. If you would like to handle the scroll event of the BODY of your html page, you’ll have to bind the event using jQuery and have a function call back to a registered function in Silverlight. In the example below I assume there’s a method “SomeMethod” and it is registered as a ScriptableObject as “RegisteredFromSilverlight” from Silverlight.   jQuery("body:first").scroll(function() { var sl = document.getElementbyId("SilverlightControl"); sl.content.RegisteredFromSilverlight.SomeMethod($(this)); });       Using jLight  in Silverlight the code would be even simpler. The registration of RegisteredFromSilverlight  as ScriptableObject can be omitted.  Besides that, you don’t have to write any JavaScript or evaluate strings with JavaScript.   jQuery.Select("body:first").scroll(SomeMethod);   Lambdas Using a lambda in Silverlight can make it even simpler.  Each is the jQuery equivalent of foreach in C#. It calls a function for every element found by jQuery. In this example all INPUT elements of the text type are selected. The FromObject method is used to create a jQueryObject from an object containing a ScriptObject. The Val method from jQuery is used to get the value of the INPUT elements.   jQuery.Select("input:text").Each((element, index) => { textBox1.Text += jQueryObject.FromObject(element).Val(); return null; });   Ajax One thing jQuery is often used for is making Ajax calls. Making calls to services to external services can be done from Silverlight, but as easy as using jQuery. As an example I would like to show how jLight does this. Below is the entire code behind. It searches my name on twitter and shows the result. This example can be found in the source of the project. The GetJson method passes a Silverlight JsonValue to a callback. This callback instantiates Twit objects and adds them to a ListBox called TwitList.   public partial class DemoPage2 : UserControl { public DemoPage2() { InitializeComponent(); jQuery.Load(); }   private void CallButton_Click(object sender, RoutedEventArgs e) { jQuery.GetJson("http://search.twitter.com/search.json?lang=en&q=sorskoot", Done); }   private void Done(JsonValue arg) { var tweets = new List<Twit>(); foreach (JsonObject result in arg["results"]) { tweets.Add(new Twit() { Text = (string)result["text"], Image = (string)result["profile_image_url"], User = (string)result["from_user"] } ); } TwitList.ItemsSource = tweets; } }   public class Twit { public string User { get; set; } public string Image { get; set; } public string Text { get; set; } }   Conclusion Although jLight is still in development it can be used already.There isn’t much documentation yet, but if you know jQuery jLight isn’t very hard to use.  If you would like to try it, please let me know what you think and report any problems you run in to. jLight can be found at:   http://jlight.codeplex.com

It is recommended that if you are using LiveWriter to go ahead and download Code Snippet with SyntaxHighlighter Support to integrate this functionality within Live Writer. 1) Log into GWB and select Options->Configure Now under the Custom CSS insert the following code at the top of the textbox: @import url("http://alexgorbatchev.com/pub/sh/current/styles/shCore.css"); @import url("http://alexgorbatchev.com/pub/sh/current/styles/shThemeDefault.css"); Please note that you can change the default theme by changing the shThemeDefault.css to one listed below: shThemeDefault.css shThemeDjango.css shThemeEmacs.css shThemeFadeToGrey.css shThemeMidnight.css shThemeRDark.css 2) Under the Static News/Announcements insert the following code at the top: <script type="text/javascript" src="http://alexgorbatchev.com/pub/sh/current/scripts/shCore.js"></script> <script type="text/javascript" language="javascript" src="http://alexgorbatchev.com/pub/sh/current/scripts/shBrushCSharp.js"></script> <script type="text/javascript" language="javascript" src="http://alexgorbatchev.com/pub/sh/current/scripts/shBrushJScript.js"></script> <script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushJava.js' type='text/javascript'></script> <script language='javascript'> SyntaxHighlighter.config.bloggerMode = true; SyntaxHighlighter.config.clipboardSwf = 'http://alexgorbatchev.com/pub/sh/current/scripts/clipboard.swf'; SyntaxHighlighter.all(); </script> Please note that this will only give you support for Java, JavaScript and C Sharp. If you want more languages like Ruby and SQL. Then add the proper tags listed below. The reason that I didn’t add them is because I do not want to load languages that I will not be blogging about. <link href='http://alexgorbatchev.com/pub/sh/current/styles/shCore.css' rel='stylesheet' type='text/css'/> <link href='http://alexgorbatchev.com/pub/sh/current/styles/shThemeDefault.css' rel='stylesheet' type='text/css'/> <script src='http://alexgorbatchev.com/pub/sh/current/scripts/shCore.js' type='text/javascript'></script> <script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushCpp.js' type='text/javascript'></script> <script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushCSharp.js' type='text/javascript'></script> <script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushCss.js' type='text/javascript'></script> <script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushJava.js' type='text/javascript'></script> <script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushJScript.js' type='text/javascript'></script> <script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushPhp.js' type='text/javascript'></script> <script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushPython.js' type='text/javascript'></script> <script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushRuby.js' type='text/javascript'></script> <script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushSql.js' type='text/javascript'></script> <script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushVb.js' type='text/javascript'></script> <script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushXml.js' type='text/javascript'></script> <script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushPerl.js' type='text/javascript'></script> <script language='javascript'> SyntaxHighlighter.config.bloggerMode = true; SyntaxHighlighter.config.clipboardSwf = 'http://alexgorbatchev.com/pub/sh/current/scripts/clipboard.swf'; SyntaxHighlighter.all(); </script> 3) Now install Code Snippet with SyntaxHighlighter Support and launch Windows Live Writer.

  • 5 Things I Learned About the IT Labor Shortage

It’s time to wrap up the series that I started back in April, “The Growing IT Labor Shortage: Are You Feeling It?” Even in a time of relatively high unemployment, labor shortages exist depending on many factors, including location, industry, IT requirements, and company size. According to Manpower Groups 2013 Talent Shortage Survey, 35% of hiring managers globally are having difficulty filling jobs. Their top three challenges in filling jobs are: 1. lack of technical competencies (hard skills) 2. Lack of available applicants 3. Lack of experience The same report listed Technicians as the most difficult position to fill in the United States For most companies, Human Capital and Talent Management have never been more strategic and they are striving for ways streamline processes, reduce turnover, and lower costs (see this Oracle whitepaper, “ Simplify Workforce Management and Increase Global Agility”). Everyone I spoke to—partner, customer, and Oracle experts—agreed that it can be extremely challenging to hire and retain IT talent in today’s labor market. And they generally agreed on the causes: a. IT is so pervasive that there are myriad moving parts requiring support and expertise, b. thus, it’s hard for university graduates to step in and contribute immediately without experience and specialization, c. big IT companies generally aren’t the talent incubators that they were in the freewheeling 90’s due to bottom line pressures that require hiring talent that can hit the ground running, and d. it’s often too expensive for resource-strapped midsize companies to invest the time and money required to get graduates up to speed. Here are my top lessons learned from my conversations with the experts. 1. A Better Title Would Have Been, “The Challenges of Finding and Retaining IT Talent That Matches Your Requirements” There are more applicants than jobs but it’s getting tougher and tougher to find individuals that perfectly fit each and every role. Top performing companies are increasingly looking to hire the “almost ready”, striving to keep their existing talent more engaged, and leveraging their employee’s social and professional networks to quickly narrow down candidate searches (here’s another whitepaper, “A Strategic Approach to Talent Management”). 2. Size Matters—But So Does Location Midsize companies must strive to build cultures that compete favorably with what large enterprises can offer, especially when they aren’t within commuting distance of IT talent strongholds. They can’t always match the compensation and benefits offered by large enterprises so it's paramount to offer candidates high quality of life and opportunities to build their resumes in alignment with their long term career aspirations. 3. Get By With a Little Help From Your Friends It doesn’t always make sense to invest time and money in training an employee on a task they will not perform frequently. Or get in a bidding war for talent with skills that are rare and in high demand. Many midsize companies are finding that it makes good economic sense to contract with partners for remote support rather than trying to divvy up each and every role amongst their lean staff. Internal staff can be assigned to roles that will have the highest positive impact on achieving organizational goals. 4. It’s Actually Both “What You Know” AND “Who You Know” If I was hiring someone today I would absolutely leverage the social and professional networks of my co-workers. Period. Most research shows that hiring in this manner is less expensive and time consuming AND produces better results. There is also some evidence that suggests new hires from employees’ networks have higher job performance and retention rates. 5. I Have New Respect for Recruiters and Hiring Managers My hats off to them—it’s not easy hiring and retaining top talent with today’s challenges. Check out the infographic, “A New Day: Taking HR from Chaos to Control”, on Oracle’s Human Capital Management solutions home page. You can also explore all of Oracle’s HCM solutions from that page based on your role. You can read all the posts in this series by clicking on the links in the right sidebar. Stay tuned…we’ll continue to post thought leadership on HCM and Talent Management topics.

  • Limiting Audit Exposure and Managing Risk – Q&A and Follow-Up Conversation

    - by Tanu Sood
    Thanks to all who attended the live ISACA webcast on Limiting Audit Exposure and Managing Risk with Metrics-Driven Identity Analytics. We were really fortunate to have Don Sparks from ISACA moderate the webcast featuring Stuart Lincoln, Vice President, IT P&L Client Services, BNP Paribas, North America and Neil Gandhi, Principal Product Manager, Oracle Identity Analytics. Stuart’s insights given the team’s role in providing IT for P&L Client Services and his tremendous experience in identity management and establishing sustainable compliance programs were true value-add at yesterday’s webcast. And if you are a healthcare organization looking to solve your compliance and security challenges, we recommend you join us for a live webcast on Tuesday, November 29 at 10 am PT. The webcast will feature experts from Kaiser Permanente, PricewaterhouseCoopers and Oracle and the focus of the discussion will be around the compliance challenges a healthcare organization faces and best practices for tackling those. Here are the details: Healthcare IT News Webcast: Managing Risk and Enforcing Compliance in Healthcare with Identity Analytics Tuesday, November 29, 201110:00 a.m. PT / 1:00 p.m. ET Register Today The ISACA webcast replay is now available on-demand and the slides are also available for download. Since we didn’t have time to address all the questions we received during the live Q&A portion of the webcast, we have captured responses to the remaining questions here. Please continue to provide us your feedback and insights from your experience in deploying identity compliance solutions. Q. Can you please clarify the mechanism utilized to populate the Identity Warehouse from each individual application's access management function / files? A. Oracle Identity Analytics (OIA) supports direct imports from applications. Data collection is based on Extract, Transform and Load (ETL) that eliminates the need to write connectors to different applications. Oracle Identity Analytics’ import engine supports complex entitlement feeds saved as either text files or XML. The imports can be scheduled on a periodic basis or triggered as needed. If the applications are synchronized with a user provisioning solution like Oracle Identity Manager, Oracle Identity Analytics has a seamless integration to pull in data from Oracle Identity Manager. Q.  Can you provide a short summary of the new features in your latest release of Oracle Identity Analytics? A. Oracle recently announced availability of enhanced Oracle Identity Analytics. This release focused on easing the certification process by offering risk analytics driven certification, advanced certification screens, business centric views and significant improvement in performance including 3X faster data imports, 3X faster certification campaign generation and advanced auto-certification features, that  will allow organizations to improve user productivity by up to 80%. Closed-loop risk feedback and IT policy monitoring with Oracle Identity Manager, a leading user provisioning solution, allows for more accurate certification reviews. And, OIA's improved performance enables customers to scale compliance initiatives supporting millions of user entitlements across thousands of applications, whether on premise or in the cloud, without compromising speed or integrity. Q. Will ISACA grant a CPE credit for attending this ISACA-sponsored webinar today? A. From ISACA: Hello and thank you for your interest in the 2011 ISACA Webinar Program!  Unfortunately, there are no CPEs offered for this program, archived or live.  We will be looking into the feasibility of offering them in the future.  Q. Would you be able to use this to help manage licenses for software? That is to say - could it track software that is not used by a user, thus eliminating the software license? A. OIA’s integration with Oracle Identity Manager, a leading user provisioning solution, allows organizations to detect ghost accounts or unused accounts via account reconciliation. Based on company’s policies, this could trigger an automated workflow for account deletion or asking for further investigation. Closed-loop feedback between the two solutions would then allow visibility into the complete audit trail of when the account was detected, the action taken, by whom, when and the current status. Q. We have quarterly attestations and .xls mechanisms are not working. Once the identity data is correlated in Identity Analytics, do you then automate access certification? A. OIA’s identity warehouse analyzes and correlates identity data across various resources that allows OIA to determine a user’s risk profile, who the access review request should go to, along with all the relevant access details of the user. The access certification manager gets notification on what to review, when and the relevant data is presented in a business friendly screen. Based on the result of the access certification process, actions are triggered and results recorded and archived. Access review managers have visual risk indicators that also allow them to prioritize access certification tasks and efforts. Q. How does Oracle Identity Analytics work with Cloud Security? A. For enterprises looking to build their own cloud(s), Oracle offers a set of security services that cloud developers can leverage including Oracle Identity Analytics.  For enterprises looking to manage their compliance requirements but without hosting those in-house and instead having a hosting provider offer managed Identity Management services to the organizations, Oracle Identity Analytics can be leveraged much the same way as you’d in an on-premise (within the enterprise) environment. In fact, organizations today are leveraging Oracle Identity Analytics to manage identity compliance in both these ways. Q. Would you recommend this as a cost effective solution for a smaller organization with @ 2,500 users? A. The key return-on-investment (ROI) on Oracle Identity Analytics is derived from automating compliance processes thereby eliminating administrative overhead, minimizing errors, maintaining cost- and time-effective sustainable compliance processes and minimizing audit exposures and penalties.  Of course, there are other tangible benefits that are derived from an Oracle Identity Analytics implementation as outlined in the webcast. For a quantitative analysis of your requirements and potential ROI calculation, we recommend you refer to the Forrester Study on Total Economic Impact of Oracle Identity Analytics. For an in-person discussion, please email Richard Caldwell.

  • The first day of JavaOne is already over!

    - by delabassee
    In the past Sunday used to be a more relaxing day with ‘just’ some JavaOne activities going on. Sunday used to be a soft day to prepare yourself for an exhausting week. This is now over as JavaOne is expanding; Sunday is now an integral part of the conference. One of the side effect of this extra day is that some activities related to JavaOne and OpenWorld such as MySQL Connect are being push to start a day earlier on Saturday (can you spot the pattern here?). On the GlassFish front, Sunday was a very busy day! It started at the Moscone Center with the annual GlassFish Community Event where the Java EE 7 and GF 4 roadmaps were presented and discussed. During the event, different GlassFish users such as ZeroTurnaround (the JRebel guys), Grupo RBS and IDR Solutions shared their views on GF, why they like GF but also what could be improved. The event was also a forum for the GF community to exchange with some of the key Java EE / GlassFish Oracle Executives and the different GF team members. The Strategy keynote and the Technical keynote were held in the Masonic Auditorium later in the after-noon. Oracle executives have presented the plans for Java SE, Java FX and Java EE. As on-demand replays will be available soon, I will not summarize several hours of content but here are some personal takeaways from those keynotes. Modularity Modularity is a big deal. We know by now that Project Jigsaw will not be ready for Java SE 8 but in any case, it is already possible (and encouraged) to test Jigsaw today. In the future, Java EE plan to rely on the modularity features provided by Java SE, so Project Jigsaw is also relevant for Java EE developers. Shorter term, to cover some of the modular requirements, Java SE will adopt the approach that was used for Java EE 6 and the notion of Profiles. This approach does not define a module system per say; Profiles is a way to clearly define different subsets of Java SE to fulfill different needs (e.g. the full JRE is not required for a headless application). The introduction of different Profiles, from the Base profile (10mb) to the Full Profile (+50mb), has been proposed for Java SE 8. Embedded Embedded is a strong theme going forward for the Java Plaform. There is now a dedicated program : Java Embedded @ JavaOne Java by nature (e.g. platform independence, built-in security, ability easily talks to any back-end systems, large set of skills available on the market, etc.) is probably the most suited platform for the Internet of Things. You can quickly be up-to-speed and develop services and applications for that space just by using your current Java skills. All you need to start developing on ARM is a 35$ Raspberry Pi ARM board (25$ if you are cheap and can live without an ethernet connection) and the recently released JDK for Linux/ARM. Obviously, GlassFish runs on Raspberry Pi. If you wan to go further in the embedded space, you should take a look Java SE Embedded, an optimized, low footprint, Java environment that support the major embedded architectures (ARM, PPC and x86). Finally, Oracle has recently introduced Java Embedded Suite, a new solution that brings modern middleware capabilities to the embedded space. Java Embedded Suite is an optimized solution that leverage Java SE Embedded but also GlassFish, Jersey and JavaDB to deploy advanced value added capabilities (eg. sensor data filtering and) deeper in the network, closer to the devices. JavaFX JavaFX is going strong! Starting from Java SE 7u6, JavaFX is bundled with the JDK. JavaFX is now available for all the major desktop platforms (Windows, Linux and Mac OS X). JavaFX is now also available, in developer preview, for low end device running Linux/ARM. During the keynote, JavaFX was shown running on a Raspberry Pi! And as announced during the keynote, JavaFX should be fully open-sourced by the end of the year; contributions are welcome!. There is a strong momentum around JavaFX, it’s the ideal client solution for the Java platform. A client layer that works perfectly with GlassFish on the back-end. If you were not convince by JavaFX, it’s time to reconsider it! As an old Chinese proverb say “One tweet is worth a thousand words!” HTML5, Project Avatar and Java EE 7 HTML5 got a lot of airtime too, it was covered during the Java EE 7 section of the keynote. Some details about Project Avatar, Oracle’s incubator project for a TSA (Thin Server Architecture) solution, were diluted and shown during the keynote. On the tooling side, Project Easel running on NetBeans 7.3 beta was demo’ed, including a cool NetBeans debugging session running in Chrome! HTML 5, Project Avatar and Java EE 7 deserve separate posts... Feedback We need your feedback! There are many projects, JSRs and products cooking : GlassFish 4, Project Jigsaw, Concurrency Utilities for Java EE (JSR 236), OpenJFX, OpenJDK to name just a few. Those projects, those specifications will have a profound impact on the Java platform for the years to come! So if you have the opportunity, download, install, learn, tests them and give feedback! Remember, you can "Make the Future Java!" Finally, the traditional GlassFish Party at the Thirsty Bear concluded the first JavaOne day. This party is another place where the community can freely exchange with the GlassFish team in a more relaxed, more friendly (but sometime more noisy) atmosphere. Arun has posted a set of pictures to reflect the atmosphere of the keynotes and the GlassFish party. You can find more details on the others Java EE and GlassFish activities here.

  • My Codemash 2011 Retrospective

    - by Greg Malcolm
    I just got back from Codemash yesterday, and still on an adrenaline buzz. Here's my take on this years encounter: The Awesome Nearly everybody in one place Codemash is the ultimate place to catch up with community friends. This is my 3rd year visiting and I've got to know a great number of very cool people through various conferences, Give Camps and other community events. I'm finding more and more that Codemash is the best place to catch up with everybody regardless of technology interest or location. Of course I always make a whole bunch more friends while I'm there! Yay! Open Spaced I found the open spaces didn't work so well last year. This year things went a lot smoother and the topics were engaging and fresh. While I miss Alan Steven's approach of running it like an agile project, it was very cool to see that it evolving. Laptops were often cracked open, not just once but frequently! For example: Jasmine - Paired on a javascript kata using the Jasmine javascript test runner J - Sat in on a J demo from local J enthusiast, Tracy Harms Watir - More pairing, this time using Ruby with the watir-webdriver through cucumber. I'd mostly forgotten that Cucumber runs just fine without Rails. It made a change to do without. The other spaces were engaging too, but I think that's enough for that topic. Javascript Shenanigans I've already mentioned that I attended a Jasmine kata session. Jasmine is close to my heart right now every since I discovered it while on the hunt for a decent Javascript testing framework for a javascript koans project earlier this year. Well, it also got covered in the Java Precompiler and Pillar's vendor session, which was great to see. Node.js was also a reoccurring theme. Node.js in a nutshell? It's an extremely scalable Event based I/O server which runs on Javascript. I'd already encountered through a Startup Weekend project and have been noticing increasing interest of late. After encountering more node.js driven excitement from my peers at codemash I absolutely had to attend the open space on it. At least 20 people turned up and by the end we had some answers, a whole ton of new questions and an impromptu user group in the form of a twitter channel (#nodemash). I have no idea where this is going to go or how big it is going to become, but if it can cross the chasm into the enterprise it could become huge... Scala Koans I'm a bit of a Koans addict, and I really need more exposure to functional languages so I gave the Scala Koans precompiler a try. Great fun! I'm really glad I attended because I found I had a whole ton of questions. Currently the koans are available here, and the answers are here. Opportunities While we're on the subject can we change the subject now? Hai Gregory, You really need to keep the drinking for later in the day. I mean seriously, you're 34 and you still do this every single time! Sure, you made it to Chad Fowler keynote ok, but you looking a rather pale weren't you? Also might have been nice to attend 'Netflicks in the Cloud' instead of 'Sleeping It Off For People Who Should Know Better'. Kthxbye PS: Stop talking to yourself Not that I entirely regret it, I've had some of my greatest insights through late night drunken conversations at the CodeMash bar. Just might be nice to reign it in a little and get something out of the next morning too. Diversity This is something that is in the back of my mind because of conversations at Codemash as well as throughout the year; I'm realizing more and more how discouraging the IT profession is for women. I notice in the community there has been a lot of attention paid to stamping out harrasment, which is good, but there also seems to be a massive PR issue. I really don't have any solutions, but I figure it can't hurt to pay more attention to whats going on... And in Other News I now have a picture of Chad Fowler giving me more cowbell! Sadly I managed to lose the cowbell later on. Hopefully it's gone to a Better Place. The Womack Family Band joined in with the musicians jam this year. There's my cowbell again! Why must you hide from me? I also finally went in the water for the first time in all the I've been coming to codemash. Why did I wait so long?!?

  • The Virtues and Challenges of Implementing Basel III: What Every CFO and CRO Needs To Know

    - by Jenna Danko
    The Basel Committee on Banking Supervision (BCBS) is a group tasked with providing thought-leadership to the global banking industry.  Over the years, the BCBS has released volumes of guidance in an effort to promote stability within the financial sector.  By effectively communicating best-practices, the Basel Committee has influenced financial regulations worldwide.  Basel regulations are intended to help banks: More easily absorb shocks due to various forms of financial-economic stress Improve risk management and governance Enhance regulatory reporting and transparency In June 2011, the BCBS released Basel III: A global regulatory framework for more resilient banks and banking systems.  This new set of regulations included many enhancements to previous rules and will have both short and long term impacts on the banking industry.  Some of the key features of Basel III include: A stronger capital base More stringent capital standards and higher capital requirements Introduction of capital buffers  Additional risk coverage Enhanced quantification of counterparty credit risk Credit valuation adjustments  Wrong  way risk  Asset Value Correlation Multiplier for large financial institutions Liquidity management and monitoring Introduction of leverage ratio Even more rigorous data requirements To implement these features banks need to embark on a journey replete with challenges. These can be categorized into three key areas: Data, Models and Compliance. Data Challenges Data quality - All standard dimensions of Data Quality (DQ) have to be demonstrated.  Manual approaches are now considered too cumbersome and automation has become the norm. Data lineage - Data lineage has to be documented and demonstrated.  The PPT / Excel approach to documentation is being replaced by metadata tools.  Data lineage has become dynamic due to a variety of factors, making static documentation out-dated quickly.  Data dictionaries - A strong and clean business glossary is needed with proper identification of business owners for the data.  Data integrity - A strong, scalable architecture with work flow tools helps demonstrate data integrity.  Manual touch points have to be minimized.   Data relevance/coverage - Data must be relevant to all portfolios and storage devices must allow for sufficient data retention.  Coverage of both on and off balance sheet exposures is critical.   Model Challenges Model development - Requires highly trained resources with both quantitative and subject matter expertise. Model validation - All Basel models need to be validated. This requires additional resources with skills that may not be readily available in the marketplace.  Model documentation - All models need to be adequately documented.  Creation of document templates and model development processes/procedures is key. Risk and finance integration - This integration is necessary for Basel as the Allowance for Loan and Lease Losses (ALLL) is calculated by Finance, yet Expected Loss (EL) is calculated by Risk Management – and they need to somehow be equal.  This is tricky at best from an implementation perspective.  Compliance Challenges Rules interpretation - Some Basel III requirements leave room for interpretation.  A misinterpretation of regulations can lead to delays in Basel compliance and undesired reprimands from supervisory authorities. Gap identification and remediation - Internal identification and remediation of gaps ensures smoother Basel compliance and audit processes.  However business lines are challenged by the competing priorities which arise from regulatory compliance and business as usual work.  Qualification readiness - Providing internal and external auditors with robust evidence of a thorough examination of the readiness to proceed to parallel run and Basel qualification  In light of new regulations like Basel III and local variations such as the Dodd Frank Act (DFA) and Comprehensive Capital Analysis and Review (CCAR) in the US, banks are now forced to ask themselves many difficult questions.  For example, executives must consider: How will Basel III play into their Risk Appetite? How will they create project plans for Basel III when they haven’t yet finished implementing Basel II? How will new regulations impact capital structure including profitability and capital distributions to shareholders? After all, new regulations often lead to diminished profitability as well as an assortment of implementation problems as we discussed earlier in this note.  However, by requiring banks to focus on premium growth, regulators increase the potential for long-term profitability and sustainability.  And a more stable banking system: Increases consumer confidence which in turn supports banking activity  Ensures that adequate funding is available for individuals and companies Puts regulators at ease, allowing bankers to focus on banking Stability is intended to bring long-term profitability to banks.  Therefore, it is important that every banking institution takes the steps necessary to properly manage, monitor and disclose its risks.  This can be done with the assistance and oversight of an independent regulatory authority.  A spectrum of banks exist today wherein some continue to debate and negotiate with regulators over the implementation of new requirements, while others are simply choosing to embrace them for the benefits I highlighted above. Do share with me how your institution is coping with and embracing these new regulations within your bank.

    Learning Outcomes Describe the operation of a memory cell Explain the difference between DRAM and SRAM Discuss the different types of ROM Explain the concepts of a hard failure and a soft error respectively Describe SDRAM organization Semiconductor Main Memory The two traditional forms of RAM used in computers are DRAM and SRAM DRAM (Dynamic RAM) Divided into two technologies… Dynamic Static Dynamic RAM is made with cells that store data as charge on capacitors. The presence or absence of charge in a capacitor is interpreted as a binary 1 or 0. Because capacitors have natural tendency to discharge, dynamic RAM requires periodic charge refreshing to maintain data storage. The term dynamic refers to the tendency of the stored charge to leak away, even with power continuously applied. Although the DRAM cell is used to store a single bit (0 or 1), it is essentially an analogue device. The capacitor can store any charge value within a range, a threshold value determines whether the charge is interpreted as a 1 or 0. SRAM (Static RAM) SRAM is a digital device that uses the same logic elements used in the processor. In SRAM, binary values are stored using traditional flip flop logic configurations. SRAM will hold its data as along as power is supplied to it. Unlike DRAM, no refresh is required to retain data. SRAM vs. DRAM DRAM is simpler and smaller than SRAM. Thus it is more dense and less expensive than SRAM. The cost of the refreshing circuitry for DRAM needs to be considered, but if the machine requires a large amount of memory, DRAM turns out to be cheaper than SRAM. SRAMS are somewhat faster than DRAM, thus SRAM is generally used for cache memory and DRAM is used for main memory. Types of ROM Read Only Memory (ROM) contains a permanent pattern of data that cannot be changed. ROM is non volatile meaning no power source is required to maintain the bit values in memory. While it is possible to read a ROM, it is not possible to write new data into it. An important application of ROM is microprogramming, other applications include library subroutines for frequently wanted functions, System programs, Function tables. A ROM is created like any other integrated circuit chip, with the data actually wired into the chip as part of the fabrication process. To reduce costs of fabrication, we have PROMS. PROMS are… Written only once Non-volatile Written after fabrication Another variation of ROM is the read-mostly memory, which is useful for applications in which read operations are far more frequent than write operations, but for which non volatile storage is required. There are three common forms of read-mostly memory, namely… EPROM EEPROM Flash memory Error Correction Semiconductor memory is subject to errors, which can be classed into two categories… Hard failure – Permanent physical defect so that the memory cell or cells cannot reliably store data Soft failure – Random error that alters the contents of one or more memory cells without damaging the memory (common cause includes power supply issues, etc.) Most modern main memory systems include logic for both detecting and correcting errors. Error detection works as follows… When data is to be read into memory, a calculation is performed on the data to produce a code Both the code and the data are stored When the previously stored word is read out, the code is used to detect and possibly correct errors The error checking provides one of 3 possible results… No errors are detected – the fetched data bits are sent out An error is detected, and it is possible to correct the error. The data bits plus error correction bits are fed into a corrector, which produces a corrected set of bits to be sent out An error is detected, but it is not possible to correct it. This condition is reported Hamming Code See wiki for detailed explanation. We will probably need to know how to do a hemming code – refer to the textbook (pg. 188 – 189) Advanced DRAM organization One of the most critical system bottlenecks when using high-performance processors is the interface to main memory. This interface is the most important pathway in the entire computer system. The basic building block of main memory remains the DRAM chip. In recent years a number of enhancements to the basic DRAM architecture have been explored, and some of these are now on the market including… SDRAM (Synchronous DRAM) DDR-DRAM RDRAM SDRAM (Synchronous DRAM) SDRAM exchanges data with the processor synchronized to an external clock signal and running at the full speed of the processor/memory bus without imposing wait states. SDRAM employs a burst mode to eliminate the address setup time and row and column line precharge time after the first access In burst mode a series of data bits can be clocked out rapidly after the first bit has been accessed SDRAM has a multiple bank internal architecture that improves opportunities for on chip parallelism SDRAM performs best when it is transferring large blocks of data serially There is now an enhanced version of SDRAM known as double data rate SDRAM or DDR-SDRAM that overcomes the once-per-cycle limitation of SDRAM

  • Day 1 - Finding Like Minds

    - by dapostolov
    So, is being a Game Developer any different from being an IT Developer? I picture a poorly lit environment where I get to purchase my own desk lamp; I'm thinking one of those huge lava lamps that pump out so much heat you could fry an egg on it. To my right: a "great wall" of empty coke cans dwarf me. Eating my last slice of pizza I look across my desk to see a fellow developer with a smug look on his face;  he's just coded his latest module for the game and it looks like he's in nirvana. My duty, of course, is to remind him to keep focused on the job at hand. So, picking up my trusty elastic and aerodynamically crafted paper bullet I begin a 10 minute war of welts and laughter which is promptly abrupted by our Project Manager demanding more details from our morning Scrum meeting. After providing about 5 minutes of geek speak and several words of comfort to make his eyes glaze over...it hits me, the idea for the module...beckoning my developer friend over, we quickly shoo the Project Manager away and begin our brainstorming frenzy ... now, where'd I put that full can of coke? OK. OK. This isn't probably the most ideal game developer environment, but it definitely sounds fun to me...and from what I gather is nothing like most game development companies. But I'm not doing this blog series to "go pro"; like I stated in my first post I want to make a 2D game from an idea my best friend and I drummed up long, long ago. I'm in this for the passion AND I want to see how easy it is for us .Net Developers to create a game. So where do I start? Where can I find like minded individuals? What technologies are there? What do I need to make a video game? The questions are endless....AND...since I already have an idea ... lets start with ... Technology (yes, I'm a geek, live with it...) Technology OK. Predominantly, games are still made in C++ or even C. I'm not sure how much assembly code is floating around lately, however, that is not my concern. I do know C / C++ from my past, enough to even get me by, but I'm mainly interested in a recent, not-so-new, technology called XNA. What is XNA? XNA allows us .Net Developers to make 2D / 3D games for windows, Xbox*, and Windows Mobile 7*. * = for a nominal fee *cough* The following link is your one stop shop to XNA game development: http://creators.xna.com/en-US/education/gettingstarted The above site hosts information such as: - getting started - a sample/instructional shooter game in 2D / 3D with code (if I'm taking too long for you in this blog series) - downloads - starter kits... http://creators.xna.com/en-US/education/starterkits/ And of course...forums. You can also subscribe and pay for their premium membership which gets you some pretty awesome tutorials, resources, downloads, and premium community support. Some general Wiki information about XNA: http://en.wikipedia.org/wiki/XNA_%28Microsoft%29 Community Support OK. Let's move on to industry and community support. Apart from XNA, there are some really cool sites out there, I just haven't found all of them yet. However, I found a really cool Game Development website called Gamastura. You can click on the following link to get you there: http://www.gamasutra.com/ The site is 100% dedicated to "The Art & Business of Making Games". Armed with blogs, twitter, jobs/resumes and most importantly industry news; one could subscribe to the feed and got lost in the wealth of information it provides. On a side note: I remember Gamasutra being around when my best friend and I wanted to make a video game...meaning, they've been around for a while now. I think the most beneficial aspect of this site is to understand the industry you want to get into. Otherwise, it's just a cool site to keep up to date with the industry in general. Another Community Support option is LinkedIn. Amongst the land of extremely bloated achievements and responsibilities lay 3 groups (that I have found) that deal with game development.: http://www.linkedin.com/groups?gid=59205 - Game Developers http://www.linkedin.com/groups?gid=824817 - DirectX Game Developer Network http://www.linkedin.com/groups?gid=756587 - DirectX Developers The Game Developers group in LinkedIn is by far the most active of the three and could possibly provide a wealth of support. What I've done thus far: - I lightly researched the XNA technology - I looked around for some community sites to assist me - I downloaded the XNA Game Studio 3.1 on my PC and installed it on my IDE - I even tried both tutorials! http://creators.xna.com/en-US/education/gettingstarted/bgintro/chapter1   Best Regards D.

  • To Bit or Not To Bit

    - by Johnm
    'Twas a long day of troubleshooting and firefighting and now, with most of the office vacant, you face a blank scripting window to create a new table in his database. Many questions circle your mind like dirty water gurgling down the bathtub drain: "How normalized should this table be?", "Should I use an identity column?", "NVarchar or Varchar?", "Should this column be NULLABLE?", "I wonder what apple blue cheese bacon cheesecake tastes like?" Well, there are times when the mind goes it's own direction. A Bit About Bit At some point during your table creation efforts you will encounter the decision of whether to use the bit data type for a column. The bit data type is an integer data type that recognizes only the values of 1, 0 and NULL as valid. This data type is often utilized to store yes/no or true/false values. An example of its use would be a column called [IsGasoline] which would be intended to contain the value of 1 if the row's subject (a car) had a gasoline engine and a 0 if the subject did not have a gasoline engine. The bit data type can even be found in some of the system tables of SQL Server. For example, the sysssispackages table in the msdb database which contains SQL Server Integration Services Package information for the packages stored in SQL Server. This table contains a column called [IsEncrypted]. A value of 1 indicates that the package has been encrypted while the value of 0 indicates that it is not. I have learned that the most effective way to disperse the crowd that surrounds the office coffee machine is to engage into SQL Server debates. The bit data type has been one of the most reoccurring, as well as the most enjoyable, of these topics. It contains a practical side and a philosophical side. Practical Consideration This data type certainly has its place and is a valuable option for database design; but it is often used in situations where the answer is really not a pure true/false response. In addition, true/false values are not very informative or scalable. Let's use the previously noted [IsGasoline] column for illustration. While on the surface it appears to be a rather simple question when evaluating a car: "Does the car have a gasoline engine?" If the person entering data is entering a row for a Jeep Liberty, the response would be a 1 since it has a gasoline engine. If the person is entering data is entering a row for a Chevrolet Volt, the response would be a 0 since it is an electric engine. What happens when a person is entering a row for the gasoline/electric hybrid Toyota Prius? Would one person's conclusion be consistent with another person's conclusion? The argument could be made that the current intent for the database is to be used only for pure gasoline and pure electric engines; but this is where the scalability issue comes into play. With the use of a bit data type a database modification and data conversion would be required if the business decided to take on hybrid engines. Whereas, alternatively, if the int data type were used as a foreign key to a reference table containing the engine type options, the change to include the hybrid option would only require an entry into the reference table. Philosophical Consideration Since the bit data type is often used for true/false or yes/no data (also called Boolean) it presents a philosophical conundrum of what to do about the allowance of the NULL value. The inclusion of NULL in a true/false or yes/no response simply violates the logical principle of bivalence which states that "every proposition is either true or false". If NULL is not true, then it must be false. The mathematical laws of Boolean logic support this concept by stating that the only valid values of this scenario are 1 and 0. There is another way to look at this conundrum: NULL is also considered to be the absence of a response. In other words, it is the equivalent to "undecided". Anyone who watches the news can tell you that polls always include an "undecided" option. This could be considered a valid option in the world of yes/no/dunno. Through out all of these considerations I have discovered one absolute certainty: When you have found a person, or group of persons, who are willing to entertain a philosophical debate of the bit data type, you have found some true friends.
