• Admin Panel like Custom Framework

  - by bhuvin

  I want to Create a Framework , like Admin panel , which can rule almost all the aspects of what is shown on the frontend. For an (most basic) example: If suppose the links which are to be shown in a navigation area is passed from the server, with the order and the url , etc. The whole aim is to save the time on the tedious tasks. You can just start creating menus and start assigning pages to it. Give a url, actual files which are to be rendered (in case of static files.), in case of dynamic files, giving the file accordingly. And all this is fully server side manageable using different portlets, sort of things. So basic Roadmap is having : Areas like: Header Area - Which can contain logos, links etc. Navigation Area - Which can contains links and submenus. Content Area - Now this is where the tricky part is that that it has zones like: left, center & right. It contains Order in which it has to be displayed. So, when someday we want to change the way the articles appear on the page, we can do so easily, without any deployments. Now these zones can have n number of internal elements, like the word cloud, or the advertisement area. Footer Area: Again similar as Header Area. Currently there is a preexisting custom framework, which uses XSLT files for pulling out data from the server side. And it has the above capabilities. For example: If there's a grid it will be having a <table> tag embedded in the XSLT file. Now whatever might be the source of the data, we serialize this as XML and give it to the XSLT file and the html is derived from this and is appended to the layer in a page. The problem with this approach is: The XSLT conversion is occurring on the server side, so the server is responsible for getting the data, running XSLT transform, and append the html generated to the layer div. So, according to me, firstly this isn't the server's concern to do so. Secondly for larger applications this might be slower. Debugging isn't possible for XSLT transformation. So, whenever we face problems with data its always a bit of a trial & error method. Maintaining it is a bit of an eerie job i.e. styling changes, and other stuff. Adding dynamic values. Like JavaScript can't actually be very easily used in this. Secondly, we can't use JQuery or any other libraries with this since this is all occurring on the server. For now what I have thought about is using Templating - Javascript - JSON combination in place of XSLT, this will be offloaded to the client and the rendering will take place accordingly. This could solve the above problems and also could add mobile support for the same. Only problem which I could think of is that: It is much work and adding new portlets on the go needs to be looked into. What could be the alternatives for this? What kind of problems are there with the JavaScript approach? What are the different ways to implement the same? Are there any existing frameworks for similar usage?

• Customer Loyalty vs. Customer Engagement: Who Cares?

  - by Jeb Dasteel-Oracle

  Have you read the recent Forbes OracleVoice blog titled Customer Loyalty is Dead. Long Live Engagement!? If you haven’t, take a look. This article prompted lots of conversation in the social realm. Many who read the article voiced their reactions to the headline and now I’m jumping in to add my view. Normal 0 false false false EN-US X-NONE X-NONE Customer loyalty is still key. It’s the effect and engagement is the cause. We at least know that to be true for our customers. We are in an age where customers are demanding to be heard. We need them to be actively involved – or engaged – as well. Greater levels of customer engagement, properly targeted, positively correlate with satisfaction. Our data has shown us this over and over. Satisfied customers are more loyal and more willing to vocalize their satisfaction through referencing, and are more likely to purchase again, all of which in turn drives incremental revenue – from the customer doing the referencing AND the customer on the receiving end of that reference. Turning this around completely, if we begin to see the level of a customer’s engagement start to wane, this is an indicator that their satisfaction, loyalty, and future revenue are likely at risk. At Oracle, we’ve put in place many programs to target, encourage, and then track engagement, allowing us to measure engagement as a determinant of loyalty. Some of these programs include our Key Accounts, solution design and architectural, Executive Sponsorship, as well as executive advisory boards. Specific programs allow us to engage specific contacts within specific customer organizations (based on role) and then systematically track their engagement activities over time, along side of tracking customer satisfaction, loyalty, referenceability, and incremental revenue contribution. Continuous measurement of engagement allows us to better understand customer views of what it means to partner with a provider and adjust program participation to better meet the needs of the partnership. We can also track across customer segments, and design new programs that are even more effective than the ones we have in place today.

• When will EBS 12.2 be released?

  - by Steven Chan (Oracle Development)

  The most frequently asked question at OpenWorld this year was, "When will EBS 12.2 be released?" Sadly, Oracle's communication policies prohibit us from speculating about release dates for unreleased software. We are not permitted to give estimates, rough timelines, guesses, or anything else that remotely resembles specific guidance on release dates. You can monitor My Oracle Support and this blog for updates on EBS 12.2.  I'll post them here as soon as they're available.  I'm embedding an old favourite from 2007 in its entirety here, since it applies equally to new releases as well as certifications. "Loose Lips Sink Ships" (March 20, 2007)If I were to sort emails in my inbox into groups, the biggest -- by far -- would be the one for emails that start with, "When will _____ be certified with the E-Business Suite?"  I answer these dutifully but know that my replies can sometimes be maddening, for two reasons:  technical uncertainty, and Oracle's rules for such communications. On the Spiral Model of CertificationsTechnology stack certifications tend to be highly iterative in nature.  As a result, statements about certification dates tend to be accurate only when made in hindsight.  Laypeople are horrified to hear this, but it's the ugly truth.  Uncertainty is simply inherent to the process.  I've become inured to it over the years, but it might come as a surprise to you that it can take many cycles to get fully-released software to work together.  Take this scenario: We test a particular combination of Component A and B. If we encounter a problem, say, with Component A, we log a bug. We receive a new version of Component A. The process iterates again. The reality is this: until a certification is completed and released, there's no accurate way of telling how many iterations are yet to come.  This is true regardless of the number of iterations that have already been completed.  Our Lips Are SealedGenerally, people understand that things are subject to change, so the second reason I can't say anything specific is actually much more important than the first.  "Loose lips might sink ships" was coined in World War II in an effort to remind people that careless talk can have serious consequences.  Curiously, this applies to Oracle's communications about upcoming features, configurations, and releases, too.  As a publicly traded company, we have very strict policies that prohibit us from linking specific releases to specific dates.  If you've ever listened to an earnings call with analysts, you'll often hear them asking, "Can you add a little more color to that statement?"  For certifications, color is usually the only thing that I have.  Sometimes I can provide a bit more information about the technical nature of the certification in question, such as expected footprints or version levels.  I can occasionally share technical issues that we've found, too, to convey the degree of risk or complexity involved in the certification.  Aside from that, there's little additional information about specific dates, date ranges, or even speculation about dates that I can provide... that is, without having one of those uncomfortable conversations with Oracle Legal.  So, as much as it pains me to do so, when it comes to dates, I'm always forced to conclude with a generic reply that blandly states one of the following: We're working on that certification right now That certification is in the pipeline but hasn't been started yet We don't have plans for that certification Don't Shoot the MessengerThankfully, I've developed a thick skin over the years -- which is a good thing, considering the colorful and energetic responses I've received over the years after answering these questions.  However, on behalf of my Oracle colleagues who are faced with these questions every day in the field, I urge you to remember that they're required to follow these same corporate rules about date disclosures.  It never hurts to ask, but don't be too disappointed if we can't provide you with a detailed answer.  The Go-Go's had it right, after all.  Related Articles Webcast Replay Available: Technical Preview of EBS 12.2 Online Patching

• Confused about modifying the sprint backlog during a sprint

  - by Maltiriel

  I've been reading a lot about scrum lately, and I've found what seem to me to be conflicting information about whether or not it's ok to change the sprint backlog during a sprint. The Wikipedia article on scrum says it's not ok, and various other articles say this as well. Also my Software Development professor taught the same thing during an overview of scrum. However, I read Scrum and XP from the Trenches and that describes a section for unplanned items on the taskboard. So then I looked up the Scrum Guide and it says that during the sprint "No changes are made that would affect the Sprint Goal" and in the discussion of the Sprint Goal "If the work turns out to be different than the Development Team expected, then they collaborate with the Product Owner to negotiate the scope of Sprint Backlog within the Sprint." It goes on to say in the discussion of the Sprint Backlog: The Sprint Backlog is a plan with enough detail that changes in progress can be understood in the Daily Scrum. The Development Team modifies Sprint Backlog throughout the Sprint, and the Sprint Backlog emerges during the Sprint. This emergence occurs as the Development Team works through the plan and learns more about the work needed to achieve the Sprint Goal. As new work is required, the Development Team adds it to the Sprint Backlog. As work is performed or completed, the estimated remaining work is updated. When elements of the plan are deemed unnecessary, they are removed. Only the Development Team can change its Sprint Backlog during a Sprint. The Sprint Backlog is a highly visible, real-time picture of the work that the Development Team plans to accomplish during the Sprint, and it belongs solely to the Development Team. So at this point I'm altogether confused. Thinking about it, it makes more sense to me to take the second approach. The individual, specific items in the backlog don't seem to me to be the most important thing, but rather the sprint goal, so not changing the sprint goal but being able to change the backlog makes sense. For instance if both the product owner and the team thought they were on the same page about a story, but as the sprint progressed they figured out there was a misunderstanding, it seems like it makes sense to change the tasks that make up that story accordingly. Or if there was some story or task that was forgotten about, but is required to reach the sprint goal, I would think it would be best to add the story or task to the backlog during the sprint. However, there are a lot of people who seem quite adamant that any change to the sprint backlog is not ok. Am I misunderstanding that position somehow? Are those folks defining the sprint backlog differently somehow? My understanding of the sprint backlog is that it consists of both the stories and the tasks they're broken down into. Anyway I would really appreciate input on this issue. I'm trying to figure out both what the idealistic scrum approach is to changing the sprint backlog during a sprint, and whether people who use scrum successfully for development allow changing the sprint backlog during a sprint.

• Broken Views

  - by Ajarn Mark Caldwell

  “SELECT *” isn’t just hazardous to performance, it can actually return blatantly wrong information. There are a number of blog posts and articles out there that actively discourage the use of the SELECT * FROM …syntax.  The two most common explanations that I have seen are: Performance:  The SELECT * syntax will return every column in the table, but frequently you really only need a few of the columns, and so by using SELECT * your are retrieving large volumes of data that you don’t need, but the system has to process, marshal across tiers, and so on.  It would be much more efficient to only select the specific columns that you need. Future-proof:  If you are taking other shortcuts in your code, along with using SELECT *, you are setting yourself up for trouble down the road when enhancements are made to the system.  For example, if you use SELECT * to return results from a table into a DataTable in .NET, and then reference columns positionally (e.g. myDataRow[5]) you could end up with bad data if someone happens to add a column into position 3 and skewing all the remaining columns’ ordinal position.  Or if you use INSERT…SELECT * then you will likely run into errors when a new column is added to the source table in any position. And if you use SELECT * in the definition of a view, you will run into a variation of the future-proof problem mentioned above.  One of the guys on my team, Mike Byther, ran across this in a project we were doing, but fortunately he caught it while we were still in development.  I asked him to put together a test to prove that this was related to the use of SELECT * and not some other anomaly.  I’ll walk you through the test script so you can see for yourself what happens. We are going to create a table and two views that are based on that table, one of them uses SELECT * and the other explicitly lists the column names.  The script to create these objects is listed below. IF OBJECT_ID('testtab') IS NOT NULL DROP TABLE testtabgoIF OBJECT_ID('testtab_vw') IS NOT NULL DROP VIEW testtab_vwgo IF OBJECT_ID('testtab_vw_named') IS NOT NULL DROP VIEW testtab_vw_namedgo CREATE TABLE testtab (col1 NVARCHAR(5) null, col2 NVARCHAR(5) null)INSERT INTO testtab(col1, col2)VALUES ('A','B'), ('A','B')GOCREATE VIEW testtab_vw AS SELECT * FROM testtabGOCREATE VIEW testtab_vw_named AS SELECT col1, col2 FROM testtabgo Now, to prove that the two views currently return equivalent results, select from them. SELECT 'star', col1, col2 FROM testtab_vwSELECT 'named', col1, col2 FROM testtab_vw_named OK, so far, so good.  Now, what happens if someone makes a change to the definition of the underlying table, and that change results in a new column being inserted between the two existing columns?  (Side note, I normally prefer to append new columns to the end of the table definition, but some people like to keep their columns alphabetized, and for clarity for later people reviewing the schema, it may make sense to group certain columns together.  Whatever the reason, it sometimes happens, and you need to protect yourself and your code from the repercussions.) DROP TABLE testtabgoCREATE TABLE testtab (col1 NVARCHAR(5) null, col3 NVARCHAR(5) NULL, col2 NVARCHAR(5) null)INSERT INTO testtab(col1, col3, col2)VALUES ('A','C','B'), ('A','C','B')goSELECT 'star', col1, col2 FROM testtab_vwSELECT 'named', col1, col2 FROM testtab_vw_named I would have expected that the view using SELECT * in its definition would essentially pass-through the column name and still retrieve the correct data, but that is not what happens.  When you run our two select statements again, you see that the View that is based on SELECT * actually retrieves the data based on the ordinal position of the columns at the time that the view was created.  Sure, one work-around is to recreate the View, but you can’t really count on other developers to know the dependencies you have built-in, and they won’t necessarily recreate the view when they refactor the table. I am sure that there are reasons and justifications for why Views behave this way, but I find it particularly disturbing that you can have code asking for col2, but actually be receiving data from col3.  By the way, for the record, this entire scenario and accompanying test script apply to SQL Server 2008 R2 with Service Pack 1. So, let the developer beware…know what assumptions are in effect around your code, and keep on discouraging people from using SELECT * syntax in anything but the simplest of ad-hoc queries. And of course, let’s clean up after ourselves.  To eliminate the database objects created during this test, run the following commands. DROP TABLE testtabDROP VIEW testtab_vwDROP VIEW testtab_vw_named

• IE9, LightSwitch Beta 2 and Zune HD: A Study in Risk Management?

  - by andrewbrust

  Photo by parl, 'Risk.’ Under Creative Commons Attribution-NonCommercial-NoDerivs License This has been a busy week for Microsoft, and for me as well.  On Monday, Microsoft launched Internet Explorer 9 at South by Southwest (SXSW) in Austin, TX.  That evening I flew from New York to Seattle.  On Tuesday morning, Microsoft launched Visual Studio LightSwitch, Beta 2 with a Go-Live license, in Redmond, and I had the privilege of speaking at the keynote presentation where the announcement was made.  Readers of this blog know I‘m a fan of LightSwitch, so I was happy to tell the app dev tools partners in the audience that I thought the LightSwitch extensions ecosystem represented a big opportunity – comparable to the opportunity when Visual Basic 1.0 was entering its final beta roughly 20 years ago.  On Tuesday evening, I flew back to New York (and wrote most of this post in-flight). Two busy, productive days.  But there was a caveat that impacts the accomplishments, because Monday was also the day reports surfaced from credible news agencies that Microsoft was discontinuing its dedicated Zune hardware efforts.  While the Zune brand, technology and service will continue to be a component of Windows Phone and a piece of the Xbox puzzle as well, speculation is that Microsoft will no longer be going toe-to-toe with iPod touch in the portable music player market. If we take all three of these developments together (even if one of them is based on speculation), two interesting conclusions can reasonably be drawn, one good and one less so. Microsoft is doubling down on technologies it finds strategic and de-emphasizing those that it does not.  HTML 5 and the Web are strategic, so here comes IE9, and it’s a very good browser.  Try it and see.  Silverlight is strategic too, as is SQL Server, Windows Azure and SQL Azure, so here comes Visual Studio LightSwitch Beta 2 and a license to deploy its apps to production.  Downloads of that product have exceeded Microsoft’s projections by more than 50%, and the company is even citing analyst firms’ figures covering the number of power-user developers that might use it. (I happen to think the product will be used by full-fledged developers as well, but that’s a separate discussion.) Windows Phone is strategic too…I wasn’t 100% positive of that before, but the Nokia agreement has made me confident.  Xbox as an entertainment appliance is also strategic.  Standalone music players are not strategic – and even if they were, selling them has been a losing battle for Microsoft.  So if Microsoft has consolidated the Zune content story and the ZunePass subscription into Xbox and Windows Phone, it would make sense, and would be a smart allocation of resources.  Essentially, it would be for the greater good. But it’s not all good.  In this scenario, Zune player customers would lose out.  Unless they wanted to switch to Windows Phone, and then use their phone’s battery for the portable media needs, they’re going to need a new platform.  They’re going to feel abandoned.  Even if Zune lives, there have been other such cul de sacs for customers.  Remember SPOT watches?  Live Spaces?  The original Live Mesh?  Microsoft discontinued each of these products.  The company is to be commended for cutting its losses, as admitting a loss isn’t easy.  But Redmond won’t be well-regarded by the victims of those decisions.  Instead, it gets black marks. What’s the answer?  I think it’s a bit like the 1980’s New York City “don’t block the box” gridlock rules: don’t enter an intersection unless you see a clear path through it.  If the light turns red and you’re blocking the perpendicular traffic, that’s your fault in judgment.  You get fined and get points on your license and you don’t get to shrug it off as beyond your control.  Accountability is key.  The same goes for Microsoft.  If it decides to enter a market, it should see a reasonable path through success in that market. Switching analogies, Microsoft shouldn’t make investments haphazardly, and it certainly shouldn’t ask investors to buy into a high-risk fund that is sold as safe and which offers only moderate returns.  People won’t continue to invest with a fund manager with a track record of over-zealous, imprudent, sub-prime investments.  The same is true on the product side for Microsoft, and not just with music players and geeky wrist watches.  It’s true of Web browsers, and line-of-business app dev tools, and smartphones, and cloud platforms and operating systems too.  When Microsoft is casual about its own risk, it raises risk for its customers, and weakens its reputation, market share and credibility.  That doesn’t mean all risk is bad, but it does mean no product team’s risk should be taken lightly. For mutual fund companies, it’s the CEO’s job to give his fund managers autonomy, but to make sure they’re conforming to a standard of rational risk management.  Because all those funds carry the same brand, and many of them serve the same investors. The same goes for Microsoft, its product portfolio, its executive ranks and its product managers.

• Windows 8/Surface Lunch Event Summary

  - by Tim Murphy

  Today was a big day for Microsoft with two separate launch event.  The first for Windows 8 and all of it’s hardware partners.  The second was specifically to introduce the Microsoft Windows 8 Surface tablet.  Below are some of the take-aways I got from the webcasts. Windows 8 Launch The three general area that Microsoft focused on were the release of the OS itself, the public unveiling of the Windows Store and the new devices available from its hardware partners. The release of the OS focused on the fact that it will be available at mid-night tonight for both new PCs and for upgrades.  I can’t say that this interested me that much since it was already known to most people.  I think what they did show well was how easy the OS really is to use. The Windows Store is also not a new feature to those of us who have been running the pre-release versions of Windows 8 or have owned Windows Phone 7 for the past 2 years.  What was interesting is that the Windows Store launches with more apps available than any other platforms store at their respective launch.  I think this says a lot about how Microsoft focuses on the ability of developers to create software and make it available.  The of course were sure to emphasize that the Windows Store has better monetary terms for developers than its competitors. The also showed off the fact that XBox Music streaming is available for to all Windows 8 user for free.  Couple this with the Bing suite of apps that give you news, weather, sports and finance right out of the box and I think most people will find the environment a joy to use. I think the hardware demo, while quick and furious, really show where Windows shine: CHOICE!  They made a statement that over 1000 devices have been certified for Windows 8.  They showed tablets, laptops, desktops, all-in-ones and convertibles.  Since these devices have industry standard connectors they give a much wider variety of accessories and devices that you can use with them. Steve Balmer then came on stage and tried to see how many times he could use the “magical”.  He focused on how the Windows 8 OS is designed to integrate with SkyDrive, Skype and Outlook.com.  He also enforced that they think Windows 8 is the best choice for the Enterprise when it comes to protecting data and integrating across devices including Windows Phone 8. With that we were left to wait for the second event of the day. Surface Launch The second event of the day started with kids with magnets.  Ok, they were adults, but who doesn’t like playing with magnets.  Steven Sinofsky detached and reattached the Surface keyboard repeatedly, clearly enjoying himself.  It turns out that there are 4 magnets in the cover, 2 for alignment and 2 as connectors. They then went to giving us the details on the display.  The 10.6” display is optically bonded to the case and is optimized to reduce glare.  I think this came through very well in the demonstrations. The properties of the case were also a great selling point.  The VaporMg allowed them to drop the device on stage, on purpose, and continue working.  Of course they had to bring out the skate boards made from Surface devices. “It just has to feel right” was the reason they gave for many of their design decisions from the weight and size of the device to the way the kickstand and camera work together.  While this gave you the feeling that the whole process was trial and error you could tell that a lot of science went into the specs.  This included making sure that the magnets were strong enough to hold the cover on and still have a 3 year old remove the cover without effort. I am glad that they also decided the a USB port would be part of the spec since it give so many options.  They made the point that this allows Surface to leverage over 420 million existing devices.  That works for me. The last feature that I really thought was important was the microSD port.  Begin stuck with the onboard memory has been an aggravation of mine with many of the devices in the market today. I think they did job of really getting the audience to understand why you want this platform and this particular device.  Using personal examples like creating a video of a birthday party and being in it or the fact that the device was being used to live blog the event and control the lights and presentation.  They showed very well that it was not only fun but very capable of getting real work done.  Handing out tablets to the crowd didn’t hurt either.  In the end I really wanted a Surface even though I really have no need for one on a daily basis.  Great job Microsoft! del.icio.us Tags: Windows 8,Win8,Windows 8 Luanch

• State of the (Commerce) Union: What the healthcare.gov hiccups teach us about the commerce customer experience

  - by Katrina Gosek

  Guest Post by Brenna Johnson, Oracle Commerce Product A lot has been said about the healthcare.gov debacle in the last week. Regardless of your feelings about the Affordable Care Act, there’s a hidden issue in this story that most of the American people don’t understand: delivering a great commerce customer experience (CX) is hard. It shouldn’t be, but it is. The reality of the government’s issues getting the healthcare site up and running smooth is something we in the online commerce community know too well.  If there’s one thing the botched launch of the site has taught us, it’s that regardless of the size of your budget or the power of an executive with a high-profile project, some of the biggest initiatives with the most attention (and the most at stake) don’t go as planned. It may even give you a moment of solace – we have the same issues! But why?  Organizations engage too many separate vendors with different technologies, running sections or pieces of a site to get live. When things go wrong, it takes time to identify the problem – and who or what is at the center of it. Unfortunately, this is a brittle way of setting up a site, making it susceptible to breaks, bugs, and scaling issues. But, it’s the reality of running a site with legacy technology constraints in today’s demanding, customer-centric market. This approach also means there’s also a lot of cooks in lots of different kitchens. You’ve got development and IT, the business and the marketing team, an external Systems Integrator to bring it all together, a digital agency or consultant, QA, product experts, 3rd party suppliers, and the list goes on. To complicate things, different business units are held responsible for different pieces of the site and managing different technologies. And again – due to legacy organizational structure and processes, this is all accepted as the normal State of the Union. Digital commerce has been commonplace for 15 years. Yet, getting a site live, maintained and performing requires orchestrating a cast of thousands (or at least, dozens), big dollars, and some finger-crossing. But it shouldn’t. The great thing about the advent of mobile commerce and the continued maturity of online commerce is that it’s forced organizations to think from the outside, in. Consumers – whether they’re shopping for shoes or a new healthcare plan – don’t care about what technology issues or processes you have behind the scenes. They just want it to work.  They want their experience to be easy, fast, and tailored to them and their needs – whatever they are. This doesn’t sound like a tall order to the American consumer – especially since they interact with sites that do work smoothly.  But the reality is that it takes scores of people, teams, check-ins, late nights, testing, and some good luck to get sites to run, and even more so at Black Friday (or October 1st) traffic levels.  The last thing on a customer’s mind is making excuses for why they can’t buy a product – just get it to work. So what is the government doing? My guess is working day and night to get the site performing  - and having to throw big money at the problem. In the meantime they’re sending frustrated online users to the call center, or even a location where a trained “navigator” can help them in-person to complete their selection. Sounds a lot like multichannel commerce (where broken communication between siloed touchpoints will only frustrate the consumer more). One thing we’ve learned is that consumers spend their time and money with brands they know and trust. When sites are easy to use and adapt to their needs, they tend to spend more, come back, and even become long-time loyalists. Achieving this may require moving internal mountains, but there’s too much at stake to ignore the sea change in how organizations are thinking about their customer. If the thought of re-thinking your internal teams, technologies, and processes sounds like a headache, think about the pain associated with losing valuable customers – and dollars. Regardless if you’re in B2B or B2C, it’s guaranteed that your competitors are making CX a priority. Those early to the game who have made CX a priority have already begun to outpace their competition. So as you’re planning for 2014, look to the news this week. Make sure the customer experience is a focus at your organization. Expectations are at record highs. Map your customer’s journey, and think from the outside, in. How easy is it for your customers to do business with you? If they interact with many touchpoints across your organization, are the call center, website, mobile environment, or brick and mortar location in sync? Do you have the technology in place to achieve this? It’s time to give the people what they want!

• Building Enterprise Smartphone App &ndash; Part 1: Why Build Smart Phone Apps

  - by Tim Murphy

  This is part 1 in a series of post based on a talk I gave recently at the Chicago Information Technology Architects Group.  Feel free to leave feedback. Intro Most of us already carry smartphones. We play games on them. We keep up with what is going on with our friends and our favorite teams. We take pictures of our kids at their events. But the question is if that is all they are good for. Many companies have aspects of their business that lend themselves to being performed by mobile devices. Some of them lean toward larger device such as tablets, but many can be executed on smartphones. This and the following articles will discuss some of the possible applications of smartphone technology for businesses, the platforms that are available and the considerations you need to make when building them. I'll take a look at some specific scenarios and wrap up with a couple of capabilities that are just emerging that can be used in the future. Why Build Enterprise Smartphone Applications So what are some of the ways that you can leverage smartphone technology to gain efficiency in your business or a clients business. There are a few major areas that I have seen mobile platforms being an advantage to. Your mobile sales force is a key candidate for leveraging smartphone apps.  They can visit clients in their retail location and place orders on site. It is a more personal approach which can gain you customer loyalty.  A sales person may also gather information about the way a client does business or who their target market is. This allows them you to focus marketing information or build customized support for your customer. You may also have need to track physical inventory in a store. This is something that has historically been done with laser scanners, but with the camera capabilities in today's phones and tablets it is possible to use more general multi-purpose devices.  This can save costs on both hardware and telecommunication contracts. Delivery verification is another area that historically has been the domain of specialized devices but can now be accomplished with smartphones.  This also reduces costs because it is also used for communicating with the driver and other operations.  Add to that the navigation capability of smartphones and you can see how the return on investment increases. Executives are always on the go. They spend most of their time in meetings and yet they need access to decision making information at their finger tips. With a smartphone app they can get alerts when major sales are closed or critical accounting process are completed that may need their attention. They can also answer questions by instantly pulling up BI reports. I have often heard operations support people say that they need things like VPN and RDP from their phones. If they can also have notifications of outages or critical support requests they can be react to situations without needing to be tied to their desks. These are all valid reasons to need smartphone applications.  In the next installment I will discuss platforms and features. del.icio.us Tags: Smartphones,Enterprise Smartphone Apps,Architecture

• Best way to process a queue in C# (PDF treatment)

  - by Bartdude

  First of all let me expose what I would like to do : I already dispose of a long-time running webapp developed in ASP.NET (C#) 2.0. In this app, users can upload standard PDF files (text+pics). The app is running in production on a Windows Server 2003 and has a dedicated database server (SQL server 2008) also running Windows Server 2003. I myself am a quite experienced web developer, but never actually programmed anything non-web (or at least nothing serious). I plan on adding a functionality to the webapp for which I would need a jpg snapshot of each page of the PDF. Creating these "thumbnails" isn't the big deal as such, I already do it inside my webapp using ghostscript. I've only done it on 1 page documents for now though, and the new functionality will need to process bigger documents. In order for this process to be transparent aswell for the admins as the final users, I would like to implement some kind of queue to delay the processing of the thumbnails. There again, no problem to create the queue, it will consist of records in a table, with enough info to find the pdf document back. Then I will need to process this queue, and that's were my interrogations start. Obviously the best solution to process it isn't an ASP script or so, so I will have to get out of my known environment. No problem, but I have no idea which direction to go. Therefore, a few questions : What should I develop ? I presumably need something that is "standby" on the server, runs when needed, then returns to idle state until further notice.Should I be looking into Windows service ? Is there another more appropriate type of project ? Depending on the first answer, what will be the approach ? Should I have somehow SQL server "tell" the program/service/... to process the queue, or should I have that program/service/... periodically check the state of the queue and treat new items. In both case, which functionality can I use ? we're not talking about hundreds of PDF a day (max 50 maybe), I can totally afford to treat the queue 1 item at a time. Can you confirm I don't have to look much further on threads and so ? (I found a lot of answers talking about threads in queue treatment, but it looks quite overkill for my needs) Maybe linked to the previous question : what about concurrent call to the program, whatever it is ? Let's suppose it is currently running, and a new record comes in the queue, what should be the behaviour ? I don't need much detailed answers and would already be happy with answers like "You can do the processing with a service, and yes it's possible to have sqlserver on machine A trigger a service start on machine B" or "You have to develop xxx and then use the scheduler to run it every xxx minutes". I don't mind reading articles and so, but I can hardly afford to spend too much time learning stuff to finally realize I went the wrong way for this project, so basically I'm trying to narrow down the scope of matters I need to investigate. Thanks for reading me, I hope I'll find some helping hands on here :-)

• IIS7 Mixed Mode Authentication

  - by drachenstern

  We're getting ready to start migrating some of our IIS6 sites to IIS7, and the application currently uses Forms Authentication. We have started getting some requests from various sites to use the Windows Authentication for the users. While this is easy enough to implement (and I've shown internally that there is no issue with the app, as expected) the question then is how to continue to keep Forms authentication for when Integrated Windows doesn't work. I've seen several walkthroughs on how to have it configured on IIS6, and I could do the same thing on IIS7, but then I have to turn on Classic Mode processing. Any solution should also be back portable to IIS6, if possible, to keep the build tree simple. So what are my options on this? Do I setup the app with Integrated Windows Authentication in IIS7, Forms Auth in the web.config, and redirect 401 errors to an "error page" allowing them to login using forms, then back to the regular app? The case when Forms is likely to be needed is going to be reserved for Contract workers, our support staff, and if someone needs to access it on their site from their Extranet. So primarily it's for our staff to login to check functionality and confirm bug reports. I suggested we just maintain that for our support staff to work, we need a Windows login that will always be live, and then we'll just enforce local responsibility on who can login to the site, but I'm told that we would do better to have Forms Authentication. Any thoughts? I can post some of the links of the articles I've already read through if that would help the forum better narrow my needs. Many thanks. tl;dr: How to do mixed mode authentication (forms, windows) in IIS7 without changing to classic pipeline and still be able to use the build in IIS6 if possible.

• MPNowPlayingInfoCenter defaultCenter will not update or retrieve information

  - by Jayson Lane

  I'm working to update the MPNowPlayingInfoCenter and having a bit of trouble. I've tried quite a bit to the point where I'm at a loss. The following is my code: self.audioPlayer.allowsAirPlay = NO; Class playingInfoCenter = NSClassFromString(@"MPNowPlayingInfoCenter"); if (playingInfoCenter) { NSMutableDictionary *songInfo = [[NSMutableDictionary alloc] init]; MPMediaItemArtwork *albumArt = [[MPMediaItemArtwork alloc] initWithImage:[UIImage imageNamed:@"series_placeholder"]]; [songInfo setObject:thePodcast.title forKey:MPMediaItemPropertyTitle]; [songInfo setObject:thePodcast.author forKey:MPMediaItemPropertyArtist]; [songInfo setObject:@"NCC" forKey:MPMediaItemPropertyAlbumTitle]; [songInfo setObject:albumArt forKey:MPMediaItemPropertyArtwork]; [[MPNowPlayingInfoCenter defaultCenter] setNowPlayingInfo:songInfo]; } This isn't working, I've also tried: [[MPNowPlayingInfoCenter defaultCenter] setNowPlayingInfo:nil]; In an attempt to get it to remove the existing information from the iPod app (or whatever may have info there). In addition, just to see if I could find out the problem, I've tried retrieving the current information on app launch: NSDictionary *info = [[MPNowPlayingInfoCenter defaultCenter] nowPlayingInfo]; NSString *title = [info valueForKey:MPMediaItemPropertyTitle]; NSString *author = [info valueForKey:MPMediaItemPropertyArtist]; NSLog(@"Currently playing: %@ // %@", title, author); and I get Currently playing: (null) // (null) I've researched this quite a bit and the following articles explain it pretty thoroughly, however, I am still unable to get this working properly. Am I missing something? Would there be anything interfering with this? Is this a service something my app needs to register to access (didn't see this in any docs)? Apple's Docs Change lock screen background audio controls Now playing info ignored UPDATE: I've created a tutorial outlining how I was able to get this functioning properly: http://jaysonlane.net/tech-blog/2012/04/lock-screen-now-playing-with-mpnowplayinginfocenter/

• CA2000 and disposal of WCF client

  - by Mayo

  There is plenty of information out there concerning WCF clients and the fact that you cannot simply rely on a using statement to dispose of the client. This is because the Close method can throw an exception (i.e. if the server hosting the service doesn't respond). I've done my best to implement something that adheres to the numerous suggestions out there. public void DoSomething() { MyServiceClient client = new MyServiceClient(); // from service reference try { client.DoSomething(); } finally { client.CloseProxy(); } } public static void CloseProxy(this ICommunicationObject proxy) { if (proxy == null) return; try { if (proxy.State != CommunicationState.Closed && proxy.State != CommunicationState.Faulted) { proxy.Close(); } else { proxy.Abort(); } } catch (CommunicationException) { proxy.Abort(); } catch (TimeoutException) { proxy.Abort(); } catch { proxy.Abort(); throw; } } This appears to be working as intended. However, when I run Code Analysis in Visual Studio 2010 I still get a CA2000 warning. CA2000 : Microsoft.Reliability : In method 'DoSomething()', call System.IDisposable.Dispose on object 'client' before all references to it are out of scope. Is there something I can do to my code to get rid of the warning or should I use SuppressMessage to hide this warning once I am comfortable that I am doing everything possible to be sure the client is disposed of? Related resources that I've found: http://www.theroks.com/2011/03/04/wcf-dispose-problem-with-using-statement/ http://www.codeproject.com/Articles/151755/Correct-WCF-Client-Proxy-Closing.aspx http://codeguru.earthweb.com/csharp/.net/net_general/tipstricks/article.php/c15941/

• JavaScriptSerializer().Serialize(Entity Framework object)

  - by loviji

  May be, it is not so problematic for you. but i'm trying first time with json serialization. and also read other articles in stackowerflow. I have created Entity Framework data model. then by method get all data from object: private uqsEntities _db = new uqsEntities(); //get all data from table sysMainTableColumns where tableName=paramtableName public List<sysMainTableColumns> getDataAboutMainTable(string tableName) { return (from column in _db.sysMainTableColumns where column.TableName==tableName select column).ToList(); } my webservice: public string getDataAboutMainTable() { penta.DAC.Tables dictTable = new penta.DAC.Tables(); var result = dictTable.getDataAboutMainTable("1"); return new JavaScriptSerializer().Serialize(result); } and jQuery ajax method $('#loadData').click(function() { $.ajax({ type: "POST", url: "WS/ConstructorWS.asmx/getDataAboutMainTable", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { $("#jsonResponse").html(msg); var data = eval("(" + msg + ")"); //do something with data }, error: function(msg) { } }); }); problem with data, code fails there. and i think i'm not use JavaScriptSerializer().Serialize() method very well. Please, tell me, what a big mistake I made in C# code?

• Windows Sharepoint Services - FullTextSqlQuery Document library Unable to find items created by SYST

  - by Ashok

  We have created an ASP.NET web app that upload files to WSS Doc Libary. The files get added under 'SYSTEM ACCOUNT' in the library. The FullTextSqlQuery class is used to search the document libary items. But it only searches files that has been uploaded by a windows user account like 'Administrator' and ignores the ones uploaded by 'SYSTEM ACCOUNT'. As a result the search results are empty even though we have the necessary data in the document library. What could be the reason for this? The code is given below: public static List GetListItemsFromFTSQuery(string searchText) { string docLibUrl = "http://localhost:6666/Articles%20Library/Forms/AllItems.aspx"; List items = new List(); DataTable retResults = new DataTable(); SPSecurity.RunWithElevatedPrivileges(delegate { using (SPSite site = new SPSite(docLibUrl)) { SPWeb CRsite = site.OpenWeb(); SPList ContRep = CRsite.GetListFromUrl(docLibUrl); FullTextSqlQuery fts = new FullTextSqlQuery(site); fts.QueryText = "SELECT Title,ContentType,Path FROM portal..scope() WHERE freetext('" + searchText + "') AND (CONTAINS(Path,'\"" + ContRep.RootFolder.ServerRelativeUrl + "\"'))"; fts.ResultTypes = ResultType.RelevantResults; fts.RowLimit = 300; if (SPSecurity.AuthenticationMode != System.Web.Configuration.AuthenticationMode.Windows) fts.AuthenticationType = QueryAuthenticationType.PluggableAuthenticatedQuery; else fts.AuthenticationType = QueryAuthenticationType.NtAuthenticatedQuery; ResultTableCollection rtc = fts.Execute(); if (rtc.Count > 0) { using ( ResultTable relevantResults = rtc[ResultType.RelevantResults]) retResults.Load(relevantResults, LoadOption.OverwriteChanges); foreach (DataRow row in retResults.Rows) { if (!row["Path"].ToString().EndsWith(".aspx")) //if (row["ContentType"].ToString() == "Item") { using ( SPSite lookupSite = new SPSite(row["Path"].ToString())) { using (SPWeb web = lookupSite.OpenWeb()) { SPFile file = web.GetFile(row["Path"].ToString()); items.Add(file.Item); } } } } } } //using ends here }); return items; }

• ASP.NET how to use __doPostBack from Custom JavaScript with Master/Content Pages

  - by harrije

  In a simple aspx page I can have a custom JavaScript function postback as described in http://www.xefteri.com/articles/show.cfm?id=18 The simple page uses a linkbutton: <asp:LinkButton id="CreateFile" runat="server" onclick="CreateFile_Click" /> with code behind that has the VB subroutine: Sub CreateFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) and a Javascript custom function that does: __doPostBack('CreateFile',''); When I move the code to a content page with a corresponding master page the simple example no longer works. I'm aware that server control IDs are changed in the generated HTML when a master page is involved, and I'm using the correct IDs in the Javascript. As an example, for the LinkButton ID I use '<%=CreateFile.ClientID%' for the Javascript in the generated HTML. Never the less, I still can't figure out how to get postbacks from the Javascript when master pages are involved. More accurately, with a master page in the mix the code won't even compile but results in: 'CreateFile_Click' is not a member of 'ASP.testmaster_aspx' If I remove onclick="CreateFile_Click" from the LinkButton markup it compiles but does not work. Similary if onclick is removed from the simpler version without a master page it does not work either, as expected. Any input on how to get postback from a custom Javascript function when using master pages would be much appreciated.

• converting 2D mouse coordinates to 3D space in OpenGL ES

  - by Jayesh

  I want to convert mouse's current X and Y coordinates into the 3D space I have drawn in the viewport. I need to do this on the OpenGL ES platform. I found following possible solutions implemented in OpenGL, but none fits what I am looking for. I found NeHe's tutorial on doing exactly this, but in traditional OpenGL way. It uses gluUnProject. http://nehe.gamedev.net/data/articles/article.asp?article=13 Although gluUnProject is not available in OpenGL ES, its implementation seems simple enough to port back. But before calling it, we need to call glReadPixels with GL_DEPTH_COMPONENT and that is not possible in OpenGL ES. (The reason I found in this thread: http://www.khronos.org/message_boards/viewtopic.php?f=4&t=771) What I want to do is similar to picking, except that I don't want to select the object but I want exact coordinates so that I can recognize particular portion of the object that is currently under mouse cursor. I went through the Picking tutorials in this answer. http://stackoverflow.com/posts/2211312/revisions But they need glRenderMode, which I believe is absent in OpenGL ES. If you know how to solve this problem in OpenGL ES, please let me know. Thanks.

• Forcing UIInterfaceOrientation changes on iPhone

  - by Andiih

  I'm strugging with getting an iPhone application which requires just about every push or pop in the Nav Controller Stack to change orientation. Basically the first view is portrait, the second landscape the third portrait again (Yes I know this is less than ideal, but that's the design and I've got to implement it). I've been through various advice on here.... http://stackoverflow.com/questions/995723/how-do-i-detect-a-rotation-on-the-iphone-without-the-device-autorotating http://stackoverflow.com/questions/1824682/force-portrait-orientation-on-pushing-new-view-to-uinavigationviewcontroller http://stackoverflow.com/questions/181780/is-there-a-documented-way-to-set-the-iphone-orientation But without total success. Setting to link against 3.1.2 my reading of the linked articles above seems to indicate that if my portrait view pushes a view with - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return ((interfaceOrientation == UIInterfaceOrientationLandscapeRight) ); } Then then that view should appear rotated to landscape. What happens is it appears in its "broken" portrait form, then rotates correctly as the device is turned. If I pop the controller back to my portrait view (which has an appropriate shouldAutoRotate...) then that remains in broken landscape view until the device is returned to portrait orientation. I've also tried removing all the shouldautorotate messages, and instead forcing rotation by transforming the view. This kind of works, and I've figured out that by moving the status bar (which is actually hidden in my application) [UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationLandscapeRight; the keyboard will appear with the correct orientation when desired. The problem with this approach is that the status bar transform is weird and ugly when you don't have a status bar - a shadow looms over the page with each change. So. What am I missing. 1) Am I wrong in thinking that in 3.1.2 (or possibly earlier) shouldAutorotateToInterfaceOrientation should provide the desired orientation simply by pushing controllers ? 2) Is there another way of getting keyboards to appear in the correct orientation. 3) Are the undocumented API calls the way to go (please no!)

• Can somebody explain the differences, status and future of the various ASP.NET AJAX libraries and to

  - by tjrobinson

  I'm confused about the differences and relationships between the various Microsoft ASP.NET AJAX components/libraries/toolkits and particularly the naming of them. It starts off relatively simple with ASP.NET AJAX itself: ASP.NET AJAX 1.0 (available for ASP.NET 2.0 in a separate package called ASP.NET 1.0 Extensions) ASP.NET AJAX 3.5 (included with ASP.NET 3.5) ASP.NET AJAX 4.0 (included with ASP.NET 4.0) Then come the various projects on CodePlex and elsewhere: ASP.NET AJAX Control Toolkit (aka Original Ajax Control Toolkit) Samples CodePlex It seems that the September 2009 Release is the final release of the Original Ajax Control Toolkit and that it's been superseded by... Ajax Control Toolkit in ASP.NET Ajax Library It looks like the old ASP.NET AJAX Control Toolkit has now become part of a larger ASP.NET Ajax Library but is still maintained seperately on CodePlex. This release is in beta at time of writing so presumably if I want to use the "Control Toolkit" I should stick with the September 2009 Release of the Original ASP.NET AJAX Control Toolkit CodePlex Microsoft Ajax Library Preview Is this the same as the ASP.NET Ajax Library mentioned above just with a confusing name variation? Is the "Control Toolkit" included in Preview 6 and is it older newer or older than the code in Ajax Control Toolkit in ASP.NET Ajax Library? CodePlex Microsoft ASP.NET Ajax Wiki - note the inconsistent insertion of ASP.NET into the name Links to useful articles, roadmaps would be useful.

• Kanban vs. Scrum

  - by Andrew Siemer

  Can someone with Kanban experience tell me how Kanban and Scrum differ? What are the pro's and con's of each of the different project management methodologies? Kanban seems to be getting a lot of press these days. I don't want to miss the hottest new way of tracking my teams failures (...and successes). Responses @S. Lott - What part of this article wasn't clear enough? infoq.com/articles/hiranabe-lean-agile-kanban/…. Do you have a more specific question? That is a great article but technically no it is not clear enough. That article gives a great amount of detail about kanban (and thank you for it...good read) but it does not specifically contrast Kanban vs. Scrum. That article will help someone like me make a decision but it most certainly won't help someone like my boss or in general someone less experienced! I was hoping for a quick overview of kanban pros and cons contrasted to scrum pros and cons. Thanks though! @S. Lott - Why do you say kanban vs. scrum? What leads you to conclude they are conflicting approaches? Can you make your question more specific? I don't think that they are necessarily conflicting. But they are different enough for a user to adhere to one over the other. Perhaps one fits a project or company better than the other? How would I sell one over the other when presenting a project management approach. Say I went to a company that was currently stuck in the rutt that is "water fall" - why would I sell one approach over the other?

• R and version control for the solo data analyst

  - by Jeromy Anglim

  Many data analysts that I respect use version control. For example: http://github.com/hadley/ See comments on http://permut.wordpress.com/2010/04/21/revision-control-statistics-bleg/ However, I'm evaluating whether adopting a version control system such as git would be worthwhile. A brief overview: I'm a social scientist who uses R to analyse data for research publications. I don't currently produce R packages. My R code for a project typically includes a few thousand lines of code for data input, cleaning, manipulation, analyses, and output generation. Publications are typically written using LaTeX. With regards to version control there are many benefits which I have read about, yet they seem to be less relevant to the solo data analyst. Backup: I have a backup system already in place. Forking and rewinding: I've never felt the need to do this, but I can see how it could be useful (e.g., you are preparing multiple journal articles based on the same dataset; you are preparing a report that is updated monthly, etc) Collaboration: Most of the time I am analysing data myself, thus, I woudln't get the collaboration benefits of version control. There are also several potential costs involved with adopting version control: Time to evaluate and learn a version control system A possible increase in complexity over my current file management system However, I still have the feeling that I'm missing something. General guides on version control seem to be addressed more towards computer scientists than data analysts. Thus, specifically in relation to data analysts in circumstances similar to those listed above: Is version control worth the effort? What are the main pros and cons of adopting version control? What is a good strategy for getting started with version control for data analysis with R (e.g., examples, workflow ideas, software, links to guides)?

Background: I doing this to extract data from a legacy application for use with other applications. This is the only way to get at this data as associated files are in a closed, proprietary, binary format. I will be using AutoItScript to drive the application to show data in its UI, then I will screenshot this and feed this to tesseract. I've already had some success in automating the UI, and have been able to use tesseract to get plain ascii text out of the bitmap. There are several AutoItScripr forum articles discussing its use with tesseract/OCR but not specifically for my question. http://www.autoitscript.com/forum/index.php?s=6c32c3ece12756e635a619cdf175eff9&showforum=2 What I need to do There are thin, 1-pixel wide rectangles that closely enclose some text, when fed to tesseract, it sees them as I for example for a verticle line of the rectangle. Any thoughts on how to remove the rectangles, or best practices? I'm asking if there is a generic command line based toolset to overwrite rectangles, for example, in .png files. I could then pass the .png through this, then pass it to tesseract. Details on the tesseract release/setup I've used are as follows: Go here: http://code.google.com/p/tesseract-ocr/downloads/list - For the basic english generic character set to get Tesseract up and running and recognising your bitmapped text into ascii text, use tesseract-2.00.eng.tar.gz (current version at time of writing is: "English language data for Tesseract (2.00 and up) Jul 2007 989 KB 84845") Related questions I have already looked at on Stack Overflow http://stackoverflow.com/questions/1335581/how-to-give-best-chance-of-success-to-an-ocr-software http://stackoverflow.com/questions/2296568/analysis-and-transformation-of-the-image-on-the-basis-of-this-analysis-for-better http://stackoverflow.com/questions/2268028/reading-characters-off-of-the-screen In these, my question is not completely answered or a commercial solution is being sold. I do not want to consider a commercial solution at this stage.
