  • F# performance vs Erlang performance, is there proof the Erlang's VM is faster?

    - by afuzzyllama
    I've been putting time into learning functional programming and I've come to the part where I want to start writing a project instead of just dabbling in tutorials/examples. While doing my research, I've found that Erlang seems to be a pretty powerful when it comes to writing concurrent software (which is my goal), but resources and tools for development aren't as mature as Microsoft development products. F# can run on linux (Mono) so that requirement is met, but while looking around on the internet I cannot find any comparisons of F# vs Erlang. Right now, I am leaning towards Erlang just because it seems to have the most press, but I am curious if there is really any performance difference between the two languages. Since I am use to developing in .NET, I can probably get up to speed with F# a lot faster than Erlang, but I cannot find any resource to convince me that F# is just as scalable as Erlang. I am most interested in simulation, which is going to be firing a lot of quickly processed messages to persistant nodes. If I have not done a good job with what I am trying to ask, please ask for more verification.

  • Extending ASP.NET Output Caching

    One of the most sure-fire ways to improve a web application's performance is to employ caching. Caching takes some expensive operation and stores its results in a quickly accessible location. Since it's inception, ASP.NET has offered two flavors of caching: Output Caching - caches the entire rendered markup of an ASP.NET page or User Control for a specified duration.Data Caching - a API for caching objects. Using the data cache you can write code to add, remove, and retrieve items from the cache.Until recently, the underlying functionality of these two caching mechanisms was fixed - both cached data in the web server's memory. This has its drawbacks. In some cases, developers may want to save output cache content to disk. When using the data cache you may want to cache items to the cloud or to a distributed caching architecture like memcached. The good news is that with ASP.NET 4 and the .NET Framework 4, the output caching and data caching options are now much more extensible. Both caching features are now based upon the provider model, meaning that you can create your own output cache and data cache providers (or download and use a third-party or open source provider) and plug them into a new or existing ASP.NET 4 application. This article focuses on extending the output caching feature. We'll walk through how to create a custom output cache provider that caches a page or User Control's rendered output to disk (as opposed to memory) and then see how to plug the provider into an ASP.NET application. A complete working example, available in both VB and C#, is available for download at the end of this article. Read on to learn more!

  • The Best Tips and Tweaks for Getting the Most Out of Internet Explorer 9

    - by Lori Kaufman
    If you use Internet Explorer 9, we have many tips and tricks for you to improve your web surfing experience, from customizing the interface to using the many features, and to make your time online more secure with IE9’s many security and privacy enhancements. Surf or Search Using the One Box (Address Bar) In IE versions prior to 9, the address bar and search bar were separate. They are now combined into the One Box in IE9, allowing you to navigate to websites or start a search from a single place. According to Microsoft, if you enter a single word that represents a valid URL, such as “microsoft” or “howtogeek,” the word will be evaluated as a URL and you can click on the URL or press Shift + Enter to load that site. The One Box also provides inline autocomplete functionality, so you only have to type a few letters to quickly get to your favorite sites. IE9 autocompletes what you are typing with popular websites, as well as with items from your Favorites and History lists. HTG Explains: What Is Windows RT and What Does It Mean To Me?

  • Using Fiddler with BizTalk's HTTP Adapter

    - by Christopher House
    I'm working on an orchestration that's retrieving some data from a Java servlet.  The servlet takes a parameter string via HTTP post and returns POX (plain old XML, no SOAP here).  I was having trouble getting a valid response from the servlet when I was sending some test messages and wanted to see what my messages were looking like as they went across the wire.  Normally I was using WCF, I'd setup message logging, but since that's obviously not an option with the HTTP adapter, my thoughts turned to Fiddler.  A quick Google search turned up some promising results.  The posts I read all referred to using Fiddler with the SOAP adapter, but I thoght I could apply the same ideas to the HTTP adapter.  This led me to try setting the following context properties: HttpRequestMessage(HTTP.UseProxy) = true; HttpRequestMessage(HTTP.ProxyName) = "127.0.0.1"; HttpRequestMessage(HTTP.ProxyPort) = 8888; I rebuilt my orch, gac'd it, bounced my host and tried submitting a test message.  Fiddler was running but I didn't see any traffic show up.  I tried fully undeploying/redeploying my application and still, no traffic in Fiddler.  I was starting to think that BizTalk was ignoring the proxy settings.  To confirm this, I closed Fiddler and submitted a test message.  Sure enough, the orch ran to completion, proving that BizTalk was ignoring the proxy settings. I went back to my orch to see if there could be any other context proprties I needed to set.  I saw one that looked promising:  HTTP.UseHandlerProxySettings.  I set this to false, rebuilt my orch and this time when I submitted, I got an error message, which made sense, I didn't have Fiddler running.  I started up Fiddler, submitted another message and there it was, my HTTP traffic, just as I hoped.  And, I was quickly able to figure out what the problem was...I had forgotten to set HTTP.ContentType to application/x-www-form-urlencoded.

  • Your Day-by-Day Guide to Agile PLM at Oracle OpenWorld 2012

    - by Kerrie Foy
    This year’s Oracle OpenWorld conference is nearly here, and we’re all excited about what we have planned! With five days of activities and customer presenters from market leaders and top innovators like The Coca-Cola Company, Starbucks, JDSU, Facebook, GlobalFoundries, and more, this is an event you don't want to miss. I've compiled this day-by-day guide to help anyone keep track of all the “Product Lifecycle Management and Product Value Chain” sessions and activities at OpenWorld 2012, September 30 – October 4 in San Francisco, California.  Monday, October 1 There are great networking activities on Sunday September 30, but PLM specific sessions start after general conference keynotes on Monday, October 1 at 10:45 a.m. at the InterContinental Hotel in room Telegraph Hill. In fact, most of our sessions this year will be held in this room, which is still close to the conference keynotes in Moscone, but just far enough away to allow some focused networking and discussions.   This first session, 10:45 – 11:45 a.m. is a joint session with the Agile and AutoVue teams, entitled “Streamline PLM Design-to-Manufacturing Processes with AutoVue Visualization Soltuions” featuring presenters from Oracle as well as joint AutoVue and Agile PLM customer GlobalFoundries. In the following 12:15 – 1:15 p.m. slot, there are two sessions to choose from, so if you have a team of representatives attending OpenWorld, you may consider splitting up to catch both of these: a) Our General Session will be held in the InterContinental Hotel Ballroom C, which will cover our complete enterprise PLM strategy, product updates, and roadmaps. It’s our pleasure to feature a customer keynote presentation from Chris Bedi, CIO, and Rajeev Sethi, Director IT Business Engagement, of JDSU. b) A focused session on integrating PLM with Engineering and Supply Chain Systems will be held on the second floor of Moscone West (next to the InterContinental) in room 2022. Join to discover how these types of integrations help companies manage common and integrated design information across all MCAD, ECAD, and software components. After a lunch break and perhaps a visit to the Demogrounds in Moscone West, select from two product roadmap sessions in the next time slot (3:15 – 4:15 p.m.): an Agile 9.3.x session located in the InterContinental’s Ballroom C, and an Agile PLM for Process session located back in the InterContinental’s Telegraph Room. Both sessions will have strong content around each product line’s latest releases, vision, and customer examples. We are very pleased to feature Daniel Soosai of Facebook in the A9 session and Vinnie D’Agostino of The Coca-Cola Company in the PLM for Process session. Afterwards, hang in there for one last session of the day from 4:45 – 5:45 p.m.; it’s an insightful discussion on leveraging Agile PLM as the Foundation for Enterprise Quality Management, and it’s sure to be one of the best. In the Telegraph Room, this session will feature Oracle experts, partner co-presenter David Bartlett from CPG Solutions, and customer co-presenter Thomas Crowe, CIO of PL Developments. Hear their experience around implementing collaborative, integrated solutions to ensure effective knowledge transfer throughout an organization, and how to perform analysis in real time to resolve product quality issues swiftly and efficiently. On Monday evening there will be plenty of industry, product, and partner dinners, so take advantage of all the networking opportunities and catch some great tunes at the 5 day Oracle OpenWorld Music Festival! Tuesday, October 2 Tuesday starts early with a special PLM Networking Brunch, sponsored by several partners, from 8:30 a.m. – 10:30 a.m. at the B Restaurant that sits atop Yerba Buena Gardens. You’ll have the unique opportunity to meet with like-minded industry peers and a PLM partner to discuss a topic of your choosing while enjoying a delicious meal. Registration is required, so to inquire about attending this brunch, please email Terri.Hiskey-AT-oracle.com. After wrapping up your conversations over brunch, head over to the Marriott Marquis in the Nob Hill CD room for a chance to experience the Oracle Product Lifecycle Analytics solution in a Hands-On Lab, open from 10:15 a.m. – 12:45 p.m. Experts will be there to answer your questions. Back in the InterContinental Hotel’s Telegraph room, the session on “Ideation and Requirements Management: Capturing the Voice of the Customer” begins at 11:45 a.m. – 12:45 p.m. This may be the session for you if you’re struggling with challenges like too many repositories of customer needs, requests, and ideas; limited visibility into which ideas are being advanced by customers and field resources; or if you’re unable to leverage internal expertise to expose effort and potential risks. This session will discuss how Agile PLM can help you overcome ideation challenges to deliver the right products to their targeted markets and fulfill customer desires. Next, from 1:15 – 2:15 p.m. join us for a session on Managing Profitable Innovation with Oracle Product Lifecycle Analytics. If you missed the Hands-on Lab, have more questions, or simply want to be inspired by the product’s forward-thinking vision and capabilities, this is a great opportunity to meet the progressive-minded executives behind the application. After this session, it may be a good opportunity to swing by the Demogrounds in Moscone West and visit the Agile PLM demos at exhibit booths #81 for Agile PLM for Discrete Manufacturing, #70 for Agile PLM for Process, and #82 for AutoVue and Agile PLM Enterprise Visualization. Check out the related Supply Chain Management booths close by if you’re interested - here's the map. There’s always lots to see and do around the exhibit area. But don’t forget the last session of the day from 5:00 p.m. – 6:00 p.m. in Telegraph Hill on Managing Product Innovation and Compliance in Life Science Companies, a “must-see” if you’re in this industry. Launching innovative products quickly is already a high-stakes challenge, but companies in the life sciences industry face uniquely severe consequences when new products don’t perform or comply as required. In recent years, more and more regulations have become mandatory, and new ones, such as REACH, are currently going into effect for several companies. Customer presenters from pharmaceutical leader Eli Lilly will share how they’ve leveraged Agile PLM to deliver high-quality, innovative products in a fast-paced, heavily regulated market environment. Tuesday evening unwind at the Supply Chain Management Reception from 6:00 – 8:00 p.m. at the premier boutique Roe Nightclub and Lounge, which is located about three blocks down on Howard Street (on the other side of Moscone from the InterContinental Hotel). Registration is required. Click here for the details.   Wednesday, October 3 We have another full line-up on Wednesday, so be ready for an action-packed day. We start with a session at 10:15 – 11:15 a.m. in the Telegraph Room where we have a session on “PLM for Consumer Products: Building an Engine for Quality and Innovation” with featured presenters from Starbucks and partner Kalypso. This is a rare opportunity to learn directly from Starbucks how they instill quality and innovation throughout their organization, products, and processes, leveraging PLM disciplines with strong support from their partner.  If you’re not in the consumer products industry, we recommend attending another session at 10:15 – 11:15 a.m. in Moscone West room 3005: “Eco-Enterprise Innovation Awards and the Business Case for Sustainability” featuring Jeff Henley, Oracle’s Chairman of the Board and Jon Chorley, Chief Sustainability Officer. Oracle will honor select customers with Oracle’s Eco-Enterprise Innovation award, which recognizes customers and their respective partners who rely on Oracle products to support their green business practices to reduce their environmental impact while improving business efficiencies and reducing costs. The awards presentation is followed by a panel discussion with customers and Oracle executives, who describe how these award-winning organizations are embracing environmental initiatives as a central part of their business strategy and how information technology plays a pivotal role. Next at 11:45 a.m. – 12:45 p.m. in Telegraph Hill attend our session devoted to exploring Product Lifecycle Management’s role in Software Lifecycle Management. This is a thought leadership session with Oracle experts in the field on the importance of change management, and we’ll discuss how Oracle has for years leveraged Agile PLM to develop Agile PLM. If software lifecycle management doesn’t apply to your business or you’d rather engage in some lively one-on-one discussions, we also have a “Supply Chain Meet the Experts” session in Moscone West Room 2001A. Product experts, thought leaders and executives will be on hand to discuss your questions/topics, so come prepared. This session tends to fill up fast so try to get in early. At 1:15 – 2:15 p.m. join us back in Telegraph Hill for a session focused on leveraging the Agile Product Portfolio Management application as the Product Development Master Schedule to improve efficiencies, optimize resources, and gain visibility across projects enterprise-wide to improve portfolio profitability. Customer presenters from Broadcom will explain how they’ve leveraged the product to enable a master schedule with enterprise-level, phase-gate program and project collaboration and resource optimization. Again in Telegraph Hill from 3:30 – 4:30 p.m. we have an interesting session with leading semiconductor customer LSI and partner Kalypso on how LSI leveraged Agile PLM to advance from homegrown applications to complete Product Value Chain Management. That type of transition can be challenging, and LSI details how they were able to achieve their goals and the value they gained along the journey – a fascinating account for any company interested in leveraging best practices to innovate their business processes and even end products. Lastly, we’ll wrap up in Telegraph Hill from 5:00 – 6:00 p.m. with a session on “Ensuring New Product Success by Achieving Excellence in New Product Introduction.” This is a cross-industry session, guaranteed to deliver insight in the often elusive practice of creating winning products, and we’re very excited about. According to IDC Manufacturing Insights analyst Joe Barkai, “Product Failures are not necessarily a result of bad ideas…they are a result of suboptimal decisions.” We’ll show you how to wire your business processes to enhance decision-making and maximize product potential. Now, quickly hit your hotel room to freshen up and then catch one of the many complimentary shuttles to the much-anticipated Oracle Customer Appreciation Event on Treasure Island. We have a very exciting show planned – check out what’s in store here. Thursday, October 4 PLM has a light schedule on Thursday this year with just one session, but this again is one of our best sessions on managing the Product Value Chain: at 11:15 a.m – 12:15 p.m.in Telegraph Hill, it’s a customer and partner driven session with Sonoco Products and Deloitte telling their story about how to achieve integrated change control by interfacing Agile PLM with Oracle E-Business Suite. Sonoco Products, a global manufacturer of consumer and industrial packaging materials, with its systems integrator, Deloitte, is doing this by implementing prebuilt integration (Oracle Design-to-Release Integration Pack for Agile Product Lifecycle Management for Process and Oracle Process) to integrate Agile with Oracle Product Hub/Oracle Product Information Management and Oracle E-Business Suite. This session presents a case study of how Sonoco is leveraging this solution to improve data quality and build a framework for stronger master data governance. Even though that ends our PLM line-up at OpenWorld, there will still be many sessions and activities at the conference, so visit the Oracle OpenWorld website to review agendas and build your schedule. And of course, download and bring this guide and the latest version of the Agile PLM Focus-On Document (available soon!). San Francisco is a wonderful city to explore, and we’re glad you’re considering joining the Agile PLM team at Oracle OpenWorld!  I hope to see you there! Follow me before the conference and on site for real-time updates about #OOW12 on Twitter @Kerrie_Foy or @AgilePLM.

  • SYS2 Scripts Updated – Scripts to monitor database backup, database space usage and memory grants now available

    - by Davide Mauri
    I’ve just released three new scripts of my “sys2” script collection that can be found on CodePlex: Project Page: http://sys2dmvs.codeplex.com/ Source Code Download: http://sys2dmvs.codeplex.com/SourceControl/changeset/view/57732 The three new scripts are the following sys2.database_backup_info.sql sys2.query_memory_grants.sql sys2.stp_get_databases_space_used_info.sql Here’s some more details: database_backup_info This script has been made to quickly check if and when backup was done. It will report the last full, differential and log backup date and time for each database. Along with these information you’ll also get some additional metadata that shows if a database is a read-only database and its recovery model: By default it will check only the last seven days, but you can change this value just specifying how many days back you want to check. To analyze the last seven days, and list only the database with FULL recovery model without a log backup select * from sys2.databases_backup_info(default) where recovery_model = 3 and log_backup = 0 To analyze the last fifteen days, and list only the database with FULL recovery model with a differential backup select * from sys2.databases_backup_info(15) where recovery_model = 3 and diff_backup = 1 I just love this script, I use it every time I need to check that backups are not too old and that t-log backup are correctly scheduled. query_memory_grants This is just a wrapper around sys.dm_exec_query_memory_grants that enriches the default result set with the text of the query for which memory has been granted or is waiting for a memory grant and, optionally, its execution plan stp_get_databases_space_used_info This is a stored procedure that list all the available databases and for each one the overall size, the used space within that size, the maximum size it may reach and the auto grow options. This is another script I use every day in order to be able to monitor, track and forecast database space usage. As usual feedbacks and suggestions are more than welcome!

  • Outstanding Silverlight User Group Meeting last night

    - by Dave Campbell
    We had a great Silverlight User Group Meeting in Phoenix last night! Before I go any farther I want to say thanks again to David Silverlight and Kim Schmidt for coming to talk to us! And not to forget Victor Gaudioso over the wire :) David, Kim, and Victor talked to us about the Silverlight User Group Starter Kit they are working on with an extended stellar list of talented developers. Don't bypass looking at this by thinking it's only for a User Group... this is a solid community-supported full-up application using MVVM and Ria Services that you could take and modify for your own use. Take a look at the list of developers. Chances are you know some of them... send them an email of thanks for all the hard work over the last year! David and Kim discussed the architecture and code, demonstrating features as they went. Then Victor came in through the application itself on a high-intensity live webcast from his home in California. The audience of about 15 seemed focused and interested which says a lot about the subject and presentation. Tim Heuer came bearing some gifts (swag) ... a hard-copy of Josh Smith's Advanced MVVM , and couple cheaply upgradeable copies of VS2008 Pro that were snatched up very quickly. We also gave away a few copies of Windows 7 Ultimate 64-bit, some Arc mice, and some Office 2007 disks... so I don't think anyone left empty-handed. Personal thanks from me go out to Mike Palermo and Tim Heuer for the surprise they had waiting for me that's been over Twitter, and to Victor for only mentioning it at least 3 times in a 5-minute webcast. Thanks for a great evening, and I look forward to seeing all of you in a couple weeks at MIX10!

  • How can I use Windows Workflow for validation of a Silverlight application?

    - by Josh C.
    I want to use Windows Workflow to provide a validation service. The validation that will be provided may have multiple tiers with chaining and redirecting to other stages of validation. The application that will generate the data for validation is a Silverlight app. I imagine the validation will take longer than the blink of an eye, so I don't want to tie the user up. Instead, I would like the user to submit the current data for validation. If the validation happens quickly, the service will perform an asynchronous callback to the app. The viewmodel that made the call would receive the validation output and post into the view. If the validation takes a long time, the user can move forward in the Silverlight app, disregarding the potential output of the validation. The viewmodel that made the call would be gone. I expect there would be another viewmodel that would contain the current validation output in its model. The validation value would change causing the user to get a notification in smaller notifcation area. I can see how the current view's viewmodel would call the validation through the viewmodel that is containing the validation output, but I am concerned that the service call will timeout. Also, I think the user may have already changed the values from the original validation, invalidating the feedback. I am sure asynchronous validation is a problem solved many times over, I am looking to glean from your experience in solving this kind of problem. Is this the right approach to the problem, or is there a better way to approach this?

  • The Internet of Things & Commerce: Part 2 -- Interview with Brian Celenza, Commerce Innovation Strategist

    - by Katrina Gosek, Director | Commerce Product Strategy-Oracle
    Internet of Things & Commerce Series: Part 2 (of 3) Welcome back to the second installation of my three part series on the Internet of Things & Commerce. A few weeks ago, I wrote “The Next 7,000 Days” about how we’ve become embedded in a digital architecture in the last 7,000 days since the birth of the internet – an architecture that everyday ties the massive expanse of the internet evermore closely with our physical lives. This blog series explores how this new blend of virtual and material will change how we shop and how businesses sell. Now enjoy reading my interview with Brian Celenza, one of the chief strategists in our Oracle Commerce innovation group. He comments on the past, present, and future of the how the growing Internet of Things relates and will relate to the buying and selling of goods on and offline. -------------------------------------------- QUESTION: You probably have one of the coolest jobs on our team, Brian – and frankly, one of the coolest jobs in our industry. As part of the innovation team for Oracle Commerce, you’re regularly working on bold features and groundbreaking commerce-focused experiences for our vision demos. As you look back over the past couple of years, what is the biggest trend (or trends) you’ve seen in digital commerce that started to bring us closer to this idea of what people are calling an “Internet of Things”? Brian: Well as you look back over the last couple of years, the speed at which change in our industry has moved looks like one of those blurred movement photos – you know the ones where the landscape blurs because the observer is moving so quickly your eye focus can’t keep up. But one thing that is absolutely clear is that the biggest catalyst for that speed of change – especially over the last three years – has been mobile. Mobile technology changed everything. Over the last three years the entire thought process of how to sell on (and offline) has shifted because of mobile technology advances. Particularly for eCommerce professionals who have started to move past the notion of “channels” for selling goods to this notion of “Mobile First”… then the Web site. Or more accurately, that everything – smartphones, web, store, tablet – is just one channel or has to act like one singular access point to the same product catalog, information and content. The most innovative eCommerce professionals realized some time ago that it’s not ideal to build an eCommerce Web site and then build everything on top of or off of it. Rather, they want to build an eCommerce API and then integrate it will all other systems. To accomplish this, they are leveraging all the latest mobile technologies or possibilities mobile technology has opened up: 4G and LTE, GPS, bluetooth, touch screens, apps, html5… How has this all started to come together for shopping experiences on and offline? Well to give you a personal example, I remember visiting an Apple store a few years ago and being amazed that I didn’t have to wait in line because a store associate knew everything about me from my ID – right there on the sales floor – and could check me out anywhere. Then just a few months later (when like any good addict) I went back to get the latest and greatest new gadget, I felt like I was stealing it because I could check myself out with my smartphone. I didn’t even need to see a sales associate OR go to a cash register. Amazing. And since then, all sort sorts of companies across all different types of industries – from food service to apparel –  are starting to see mobile payments in the billions of dollars now thanks not only to the convenience factor but to smart loyalty rewards programs as well. These are just some really simple current examples that come to mind. So many different things have happened in the last couple of years, it’s hard to really absorb all of the quickly – because as soon as you do, everything changes again! Just like that blurry speed photo image. For eCommerce, however, this type of new environment underscores the importance of building an eCommerce API – a platform that has services you can tap in to and build on as the landscape changes at a fever pitch. It’s a mobile first perspective. A web service perspective – particularly if you are thinking of how to engage customers across digital and physical spaces. —— QUESTION: Thanks for bringing us into the present – some really great examples you gave there to put things into perspective. So what do you see as the biggest trend right now around the “Internet of Things” – and what’s coming next few years? Brian: Honestly, even sitting where I am in the innovation group – it’s hard to look out even 12 months because, well, I don’t even think we’ve fully caught up with what is possible now. But I can definitely say that in the last 12 months and in the coming 12 months, in the technology and eCommerce world it’s all about iBeacons. iBeacons are awesome tools we have right now to tie together physical and digital shopping experiences. They know exactly where you are as a shopper and can communicate that to businesses. Currently there seem to be two camps of thought around iBeacons. First, many people are thinking of them like an “indoor GPS”, which to be fair they literally are. The use case this first camp envisions for iBeacons is primarily for advertising and marketing. So they use iBeacons to push location-based promotions to customers if they are close to a store or in a store. You may have seen these types of mobile promotions start to pop up occasionally on your smart phone as you pass by a store you’ve bought from in the past. That’s the work of iBeacons. But in my humble opinion, these promotions probably come too early in the customer journey and although they may be well timed and work to “convert” in some cases, I imagine in most they are just eroding customer trust because they are kind of a “one-size-fits-all” solution rather than one that is taking into account what exactly the customer might be looking for in that particular moment. Maybe they just want more information and a promotion is way too soon for that type of customer. The second camp is more in line with where my thinking falls. In this case, businesses take a more sensitive approach with iBeacons to customers’ needs. Instead of throwing out a “one-size-fits-all” to any passer by with iBeacons, the use case is more around looking at the physical proximity of a customer as an opportunity to provide a service: show expert reviews on a product they may be looking at in a particular aisle of a store, offer the opportunity to compare prices (and then offer a promotion), signal an in-store associate if a customer has been in the store for more than 10 minutes in one place. These are all less intrusive more value-driven uses of iBeacons. And they are more about building customer trust through service. To take this example a bit further into the future realm of “Big Data” and “Internet of Things” businesses could actually use the Oracle Commerce Platform and iBeacons to “silently” track customer movement w/in the store to provide higher quality service. And this doesn’t have to be creepy or intrusive. Simply if a customer has been in a particular department or aisle for more than a 5 or 10 minutes, an in-store associate could come over an offer some assistance already knowing customer preferences from their online profile and maybe even seeing the items in a shopping cart they started at home. None of this has to be revealed to the customer, but it certainly could boost the level of service an in-store sales associate could provide. Or, in another futuristic example, stores could use the digital footprint of the physical store transmitted by iBeacons to generate heat maps of the store that could be tracked over time. Imagine how much you could find out about which parts of the store are more busy during certain parts of the day or seasons. This could completely revolutionize how physical merchandising is deployed or where certain high value / new items are placed. And / or this use of iBeacons could also help businesses figure out if customers are getting held up in certain parts of the store during busy days like Black Friday. If long lines are causing customers to bounce from a physical store and leave those holiday gifts behind, maybe having employees with mobile check as an option could remove the cash register bottleneck. But going to back to my original statement, it’s all still very early in the story for iBeacons. The hardware manufacturers are still very new and there is still not one clear standard.  Honestly, it all goes back to building and maintaining an extensible and flexible platform for anywhere engagement. What you’re building today should allow you to rapidly take advantage of whatever unimaginable use cases wait around the corner. ------------------------------------------------------ I hope you enjoyed the brief interview with Brian. It’s really awesome to have such smart and innovation-minded individuals on our Oracle Commerce innovation team. Please join me again in a few weeks for Part 3 of this series where I interview one of the product managers on our team about how the blending of digital and in-store selling in influencing our product development and vision.

    - by Susanne Hale
    Updates come from the Documaker front on two counts: Oracle Documaker Awarded XCelent Award for Best Functionality Celent has published a NEW report entitled Document Automation Solution Vendors for Insurers 2011. In the evaluation, Oracle received the XCelent award for Functionality, which recognizes solutions as the leader in this category of the evaluation. According to Celent, “Insurers need to address issues related to the creation and handling of all sorts of documents. Key issues in document creation are complexity and volume. Today, most document automation vendors provide an array of features to cope with the complexity and volume of documents insurers need to generate.” The report ranks ten solution providers on Technology, Functionality, Market Penetration, and Services. Each profile provides detailed information about the vendor and its document automation system, the professional services and support staff it offers, product features, insurance customers and reference feedback, its technology, implementation process, and pricing.  A summary of the report is available at Celent’s web site. Documaker User Group in Wisconsin Holds First Meeting Oracle Documaker users in Wisconsin made the first Documaker User Group meeting a great success, with representation from eight companies. On April 19, over 25 attendees got together to share information, best practices, experiences and concepts related to Documaker and enterprise document automation; they were also able to share feedback with Documaker product management. One insurer shared how they publish and deliver documents to both internal and external customers as quickly and cost effectively as possible, since providing point of sale documents to the sales force in real time is crucial to obtaining and maintaining the book of business. They outlined best practices that ensure consistent development and testing strategies processes are in place to maximize performance and reliability. And, they gave an overview of the supporting applications they developed to monitor and improve performance as well as monitor and track each transaction. Wisconsin User Group meeting photos are posted on the Oracle Insurance Facebook page http://www.facebook.com/OracleInsurance. The Wisconsin User Group will meet again on October 26.

  • When Do OS Questions Belong on Hardware Service Requests?

    - by Get Proactive Customer Adoption Team
    Untitled Document My Oracle Support—Logging an Operating System Service Request One of the concerns we hear from our customers with Premier Support for Systems is that they have difficulty logging a Service Request (SR) for an operating system issue. Because Premier Support for Systems includes support for the hardware and the associated operating system, you log any operating system issues through a hardware Service Request. To create a hardware Service Request, you enter the information into the Hardware tab of the Create Service Request screen, but to ensure that the hardware Service Request you enter is recognized and routed appropriately for an operating system issue, you need to change the product from your specific hardware to the operating system that the hardware is running. The example below shows you how to create a Service Request for the operating system when the support level is Premier Support for Systems. The key to success is remembering that the operating system coverage is part of the hardware support. To begin, from anywhere within My Oracle Support, click on the Create SR button as you would to log any SR: Enter your Problem Summary and the Problem Description Next, click on the Hardware tab. Enter the System Serial Number (in this case “12345”) and click on Validate Serial Number: Notice that the product name for the hardware indicates “Sunfire T2000 Server” with an option for a drop down List of Values. Click on the product drop down and choose the correct operating system from the list. In this case I have chosen “OpenSolaris Operating System” Next, you will need to enter the correct operating system version: At this point, you may proceed to complete and submit the Service Request. If your company has Premier Support for Systems, just remember that your operating system has coverage under the hardware it runs on, so start with a Hardware tab on the Service Request screen and change the product related information to reflect the operating system you need help with. Following these simple steps will ensure that the system assigns your Service Request to the right support team for an operating system issue and the support engineer can quickly begin working your issue.

  • SQL SERVER – Attach or Detach Database – SQL in Sixty Seconds #068

    - by Pinal Dave
    When we have to move a database from one server to another server or when we have to move a database from one file to another file, we commonly use Database Attach or Detach process. I have been doing this for quite a while as well. Recently, when I was visiting an organization I found that in this organization lots of developers are still using an older version of the code to attach the database. I quickly pointed that out to them the new method to attach the database, however it was really interesting to find out that they really did not know that sp_attach_db is now a deprecated method to attach the database. This really made me to do today’s SQL in Sixty Seconds. I demonstrate in this SQL in Sixty Seconds how to attach or detach the database using a new method of attaching database. The code which I have used in this code is over here: -- Detach Database USE [master] GO EXEC MASTER.dbo.sp_detach_db @dbname = N'AdventureWorks2014_new' GO -- Deprecated Way to Attach Database USE [master] GO EXEC MASTER.dbo.sp_attach_db 'AdventureWorks2014_new', 'E:\AdventureWorks2012_Data_new.mdf', 'E:\AdventureWorks2012_log_new.ldf' GO -- Correct Way to Attach Database USE [master] GO CREATE DATABASE [AdventureWorks2014_new] ON ( FILENAME = 'E:\AdventureWorks2012_Data_new.mdf'), ( FILENAME = 'E:\AdventureWorks2012_log_new.ldf') FOR ATTACH GO Here is the question back to you – Do you still use old methods to attach database? If yes, I suggest that you start using the new method onwards. SQL in Sixty Seconds Video I have attempted to explain the same subject in simple words over in following video. Action Item Here are the blog posts I have previously written on the subject of SA password. You can read it over here: SQL SERVER – 2005 – T-SQL Script to Attach and Detach Database SQL SERVER – Move Database Files MDF and LDF to Another Location SQL SERVER – 2005 Take Off Line or Detach Database SQL SERVER – Attach mdf file without ldf file in Database SQL SERVER – Copy Database from Instance to Another Instance – Copy Paste in SQL Server You can subscribe to my YouTube Channel for frequent updates.

  • Formating Columns in Excel created by af:exportCollectionActionListener

    - by Duncan Mills
    The af:exportCollectionActionListener behavior in ADF Faces Rich client provides a very simple way of quickly dumping out the contents or selected rows in a table or treeTable to Excel. However, that simplicity comes at a price as it pretty much left up to Excel how to format the data. A common use case where you have a problem is that of ID columns which are often long numerics. You probably want to represent this data as a string, Excel however will probably have other ideas and render it as an exponent  - not what you intended. In earlier releases of the framework you could sort of work around this by taking advantage of a bug which would allow you to surround the outputText in question with invisible outputText components which provided formatting hints to Excel. Something like this: <af:column headertext="Some wide label">  <af:panelgrouplayout layout="horizontal">     <af:outputtext value="=TEXT(" visible="false">     <af:outputtext value="#{row.bigNumberValue}" rendered="true"/>    <af:outputtext value=",0)" visible="false">   </af:panelgrouplayout> </af:column> However, this bug was fixed and so it can no longer be used as a trick, the export now ignores invisible columns. So, if you really need control over the formatting there are several alternatives: First the more powerful ADF Desktop Integration (ADFdi) package which allows you to build fully transactional spreadsheets that "pull" the data and can update it. This gives you all the control that might need on formatting but it does need specific Excel Add-ins on the client to work. For more information about ADFdi have a look at this tutorial on OTN. Or you can of course look at BI Publisher or Apache POI if you're happy with output only spreadsheets

  • Introducing Kiddo: A Ruby DSL for building simple WPF and Silverlight applications

    - by fdumlao
    Read the original article here... As a long time Ruby lover and deep rooted .NET supporter, I was probably more psyched than anyone I knew when IronRuby 1.0 was finally released. I immediately grabbed and started building some apps with it to see where the boundaries were going to lie between IronRuby and ruby.exe, and so far I've been pleasantly surprised by how many things just work as I'd expect. I then started to try out some of my favorite libs that I was sure would not work with IronRuby, and I wasn't surprised at all when _why's amazing Shoes library didn't work. Being somewhat familiar with Shoes (it's a great DSL for building simple UIs in Ruby) I felt it wouldn't be that difficult to port it over and as it turned out, someone else had already started the work. As cool as this was, I was never quite satisfied with good 'ol shoes. While it was quite complete, it lacked simple extensibility points, and although easy, it wasn't quite "kid friendly". At the same time on the .NET side of the fence, IronRuby could easily compile XAML to create WPF and Silverlight UIs, but trying to do it declaratively in plain Ruby was no fun at all. And so, the Shoes-inspired, WPF/Silverlight GUI DSL was born. (and it lives here: http://bitbucket.org/fdumlao/kiddo/src) Introducing Kiddo Tell you what. Let's start with a quick code example first. We'll build a useful app that we can use to quickly reverse strings whenever we need it. Read the complete article here...

  • Book Review - Programming Windows Azure by Siriram Krishnan

    - by BuckWoody
    As part of my professional development, I’ve created a list of books to read throughout the year, starting in June of 2011. This a review of the first one, called Programming Windows Azure by Siriram Krishnan. You can find my entire list of books I’m reading for my career here: http://blogs.msdn.com/b/buckwoody/archive/2011/06/07/head-in-the-clouds-eyes-on-the-books.aspx  Why I Chose This Book: As part of my learning style, I try to read multiple books about a single subject. I’ve found that at least 3 books are necessary to get the right amount of information to me. This is a “technical” work, meaning that it deals with technology and not business, writing or other facets of my career. I’ll have a mix of all of those as I read along. I chose this work in addition to others I’ve read since it covers everything from an introduction to more advanced topics in a single book. It also has some practical examples of actually working with the product, particularly on storage. Although it’s dated, many examples normally translate. I also saw that it had pretty good reviews. What I learned: I learned a great deal about storage, and many useful code snippets. I do think that there could have been more of a focus on the application fabric - but of course that wasn’t as mature a feature when this book was written. I learned some great architecture examples, and in one section I learned more about encryption. In that example, however, I would rather have seen the examples go the other way - the book focused on moving data from on-premise to Azure storage in an encrypted fashion. Using the Application Fabric I would rather see sensitive data left in a hybrid fashion on premise, and connect to for the Azure application. Even so, the examples were very useful. If you’re looking for a good “starter” Azure book, this is a good choice. I also recommend the last chapter as a quick read for a DBA, or Database Administrator. It’s not very long, but useful. Note that the limits described are incorrect - which is one of the dangers of reading a book about any cloud offering. The services offered are updated so quickly that the information is in constant danger of being “stale”. Even so, I found this a useful book, which I believe will help me work with Azure better. Raw Notes: I take notes as I read, calling that process “reading with a pencil”. I find that when I do that I pay attention better, and record some things that I need to know later. I’ll take these notes, categorize them into a OneNote notebook that I synchronize in my Live.com account, and that way I can search them from anywhere. I can even read them on the web, since the Live.com has a OneNote program built in. Note that these are the raw notes, so they might not make a lot of sense out of context - I include them here so you can watch my though process. Programming Windows Azure by Siriram Krishnan: Learning about how to select applications suitable for Distributed Technology. Application Fabric gets the least attention; probably because it was newer at the time. Very clear (Chapter One) Good foundation Background and history, but not too much I normally arrange my descriptions differently, starting with the use-cases and moving to physicality, but this difference helps me. Interesting that I am reading this using Safari Books Online, which uses many of these concepts. Taught me some new aspects of a Hypervisor – very low-level information about the Azure Fabric (not to be confused with the Application Fabric feature) (Chapter Two) Good detail of what is included in the SDK. Even more is available now. CS = Cloud Service (Chapter 3) Place Storage info in the configuration file, since it can be streamed in-line with a running app. Ditto for logging, and keep separated configs for staging and testing. Easy-switch in and switch out.  (Chapter 4) There are two Runtime API’s, one of external and one for internal. Realizing how powerful this paradigm really is. Some places seem light, and to drop off but perhaps that’s best. Managing API is not charged, which is nice. I don’t often think about the price, until it comes to an actual deployment (Chapter 5) Csmanage is something I want to dig into deeper. API requires package moves to Blob storage first, so it needs a URL. Csmanage equivalent can be written in Unix scripting using openssl. Upgrades are possible, and you use the upgradeDomainCount attribute in the Service-Definition.csdef file  Always use a low-privileged account to test on the dev fabric, since Windows Azure runs in partial trust. Full trust is available, but can be dangerous and must be well-thought out. (Chapter 6) Learned how to run full CMD commands in a web window – not that you would ever do that, but it was an interesting view into those links. This leads to a discussion on hosting other runtimes (such as Java or PHP) in Windows Azure. I got an expanded view on this process, although this is where the book shows its age a little. Books can be a problem for Cloud Computing for this reason – things just change too quickly. Windows Azure storage is not eventually consistent – it is instantly consistent with multi-phase commit. Plumbing for this is internal, not required to code that. (Chapter 7) REST API makes the service interoperable, hybrid, and consistent across code architectures. Nicely done. Use affinity groups to keep data and code together. Side note: e-book readers need a common “notes” feature. There’s a decent quick description of REST in this chapter. Learned about CloudDrive code – PowerShell sample that mounts Blob storage as a local provider. Works against Dev fabric by default, can be switched to Account. Good treatment in the storage chapters on the differences between using Dev storage and Azure storage. These can be mitigated. No, blobs are not of any size or number. Not a good statement (Chapter 8) Blob storage is probably Azure’s closest play to Infrastructure as a Service (Iaas). Blob change operations must be authenticated, even when public. Chapters on storage are pretty in-depth. Queue Messages are base-64 encoded (Chapter 9) The visibility timeout ensures processing of message in a disconnected system. Order is not guaranteed for a message, so if you need that set an increasing number in the queue mechanism. While Queues are accessible via REST, they are not public and are secured by default. Interesting – the header for a queue request includes an estimated count. This can be useful to create more worker roles in a dynamic system. Each Entity (row) in the Azure Table service is atomic – all or nothing. (Chapter 10) An entity can have up to 255 Properties  Use “ID” for the class to indicate the key value, or use the [DataServiceKey] Attribute.  LINQ makes working with the Azure Table Service much easier, although Interop is certainly possible. Good description on the process of selecting the Partition and Row Key.  When checking for continuation tokens for pagination, include logic that falls out of the check in case you are at the last page.  On deleting a storage object, it is instantly unavailable, however a background process is dispatched to perform the physical deletion. So if you want to re-create a storage object with the same name, add retry logic into the code. Interesting approach to deleting an index entity without having to read it first – create a local entity with the same keys and apply it to the Azure system regardless of change-state.  Although the “Indexes” description is a little vague, it’s interesting to see a Folding and Stemming discussion a-la the Porter Stemming Algorithm. (Chapter 11)  Presents a better discussion of indexes (at least inverted indexes) later in the chapter. Great treatment for DBA’s in Chapter 11. We need to work on getting secondary indexes in Table storage. There is a limited form of transactions called “Entity Group Transactions” that, although they have conditions, makes a transactional system more possible. Concurrency also becomes an issue, but is handled well if you’re using Data Services in .NET. It watches the Etag and allows you to take action appropriately. I do not recommend using Azure as a location for secure backups. In fact, I would rather have seen the examples in (Chapter 12) go the other way, showing how data could be brought back to a local store as a DR or HA strategy. Good information on cryptography and so on even so. Chapter seems out of place, and should be combined with the Blob chapter.  (Chapter 13) on SQL Azure is dated, although the base concepts are OK.  Nice example of simple ADO.NET access to a SQL Azure (or any SQL Server Really) database.

  • MBA versus MSIS

    - by user794684
    I am considering going back to school for my masters and I've been looking at several avenues I can take. I've been considering either an MBA or an MSIS degree. Overall I know that an MBA is going to give me a solid skill set that can help me become an executive. However they seem to be a dime a dozen these days and the University I can get into is good, but it's not exactly in the top 100 anything. My undergrad MINOR was in Business Information Systems. I'm rusty as hell, considering I haven't touched it, but an MSIS would be more in the direction of my past academic experience and seems to touch both on business management and IT. Question... With an MSIS will I just be a middleman? Will I really be an important person with a real skill set or will I merely be someone who isn't quite cut out to be a manager and who is clueless about the tech side? Is an MSIS degree going to give me a real chance to move up the pay scale quickly or am I better off learning programing, networking through another BS degree? What will give me more upward mobility career wise? An MBA or an MSIS?

  • How do you research while pair programming?

    - by traffichazard
    I've recently started at a new job and pairing has helped me become effective there very quickly. I am, however, having a hard time when we must do brief joint research during our workflow, covering API features, code examples, or command options. My team lead urges us to do all research on our pairing station, rather than our individual laptops, and to synchronize our research by verbally negotiating the steps between different web resources. I research, read, and absorb information differently from my pairing partner, and I feel much more productive when I can follow a thread of research to the next web page exactly when I want to, rather than trying to keep exact pace and place with what my partner's reading. We're both smart and fast, but we can't help moving in different ways and instantaneous velocities when we're figuring stuff out. It seems so much easier to poke around individually for a minute until one of us says "I've got it," then get back together and code. When you pair program, how do you handle short research tasks? What works best for you, and how to you keep in sync with your partner?

  • Finetuning movement based on gradual rotation towards a target

    - by A.B.
    I have an object which moves towards a target destination by gradually adjusting its facing while moving forwards. If the target destination is in a "blind spot", then the object is incapable of reaching it. This problem is ilustrated in the picture below. When the arrow is ordered to move to point A, it will only end up circling around it (following the red circle) because it is not able to adjust its rotation quickly enough. I'm interested in a solution where the movement speed is multiplied by a number from 0.1 to 1 in proportion to necessity. The problem is, how do I calculate whether it is necessary in the first place? How do I calculate an appropriate multiplier that is neither too small nor too large? void moveToPoint(sf::Vector2f destination) { if (destination == position) return; auto movement_distance = distanceBetweenPoints(position, destination); desired_rotation = angleBetweenPoints(position, destination); /// Check whether rotation should be adjusted if (rotation != desired_rotation) { /// Check whether the object can achieve the desired rotation within the next adjustment of its rotation if (Radian::isWithinDistance(rotation, desired_rotation, rotation_speed)) { rotation = desired_rotation; } else { /// Determine whether to increment or decrement rotation in order to achieve desired rotation if (Radian::convert(desired_rotation - rotation) > 0) { /// Increment rotation rotation += rotation_speed; } else { /// Decrement rotation rotation -= rotation_speed; } } } if (movement_distance < movement_speed) { position = destination; } else { position.x = position.x + movement_speed*cos(rotation); position.y = position.y + movement_speed*sin(rotation); } updateGraphics(); }
