• Building Tag Cloud Declarative ADF Component

  - by Arunkumar Ramamoorthy

  When building a website, there could a requirement to add a tag cloud to let the users know the popular tags (or terms) used in the site. In this blog, we would build a simple declarative component to be used as tag cloud in the page. To start with, we would first create the declarative component, which could display the tag cloud. We will do that by creating a new custom application from the new gallery. Give a name for the app and the project and from the new gallery, let us create a new ADF Declarative Component We need to specify the name for the declarative component, attributes in it etc. as follows For displaying the tags as cloud, we need to pass the content to this component. So, we will create an attribute to hold the values for the tag. Let us name it as "value" and make it as java.lang.String  type. Once after this, to hold the component, we need to create a tag library. This can be done by clicking on the Add Tag Library button. Clicking on OK buttons in all the open dialogs would create a declarative component for us. Now, we need to display the tag cloud based on the value passed to the component. To do that, we assume that the value is a Tree Binding and has two attributes in it, say "Name" and "Weight". To make a tag cloud, we would put together the "Name" in a loop and set it's font size based on the "Weight". After putting our logic to work, here is how the source look Attributes added to the declarative components can be retrieved by using #{attrs.<attribute_name>}. Now, we need to deploy this project as ADF Library Jar file, so that this can be distributed to the consuming applications. We'll select ADF Library Jar as type and create the profile. We would be getting the jar file after deployment. To test the functionality, we could create a simple Fusion Web Application. To add our custom component to the consuming application, we can create a file system connection pointing to the location where the jar file is and add it or, add through the project properties of the ViewController project. Now, our custom component has been added to the consuming application. We could test that by creating a VO in the model project with a query like, select 'Faces' as Name,25 as Weight from dual union all select 'ADF', 15 from dual  union all select 'ADFdi', 30 from dual union all select 'BC4J', 20 from dual union all select 'EJB', 40 from dual union all select 'WS', 35 from dual Add this VO to the AppModule, so that it would be exposed to the data control. Then, we could create a jspx page, and add a tree binding to the VO created. We can now see our Tag Cloud declarative component is available in the component palette.  It can be inserted from the component palette to our page and set it's value property to CollectionModel of the tree binding created. Now that we've created the Declarative component and added that to our page successfully, we can run the page to see how it looks. As per the query, the Tags are displayed in different fonts, based on their weight.

• Java-Powered Robot Named NAO Wows Crowds

  - by Tori Wieldt

  He drew a crowd where he went at JavaOne. And only being 22.5 inches/573 mm tall, that's pretty impressive. Nao (pronounced now) is an autonomous, programmable humanoid robot developed by Aldebaran Robotics, a French robotics company. Over 200 academic institutions worldwide have made use of the robot. In this video from JavaOne, Nicolas Rigaud shows off the NAO robot which you can control with Java. We are eager to see what Java developers can do with a robot that can walk, talk, see, hear, and dance. &amp;amp;amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;amp;amp;quot;&amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;amp;amp;gt; You can see several pictures in the blog Aldebaran Robotics at JavaOne.

• What standards to use in Business Process Modelling?

  - by user1268690

  There are several approaches on how to model a business process in software applications (BPM software). For instance, a processes can be described in BPMN, EPC, IDEF0, SOMF, etc. Additionally, different process execution languages such as BPEL, RPC, Wf-XML are available. If I were to develop software for the BPM-market, which standards should I implement or focus on? Which standards are most suitable if my BPM software was going to be implemented in my client's IT-System?

• Same SELECT used in an INSERT has different execution plan

  - by amacias

  A customer complained that a query and its INSERT counterpart had different execution plans, and of course, the INSERT was slower. First lets look at the SELECT : SELECT ua_tr_rundatetime,        ua_ch_treatmentcode,        ua_tr_treatmentcode,        ua_ch_cellid,        ua_tr_cellid FROM   (SELECT DISTINCT CH.treatmentcode AS UA_CH_TREATMENTCODE,                         CH.cellid        AS UA_CH_CELLID         FROM    CH,                 DL         WHERE  CH.contactdatetime > SYSDATE - 5                AND CH.treatmentcode = DL.treatmentcode) CH_CELLS,        (SELECT DISTINCT T.treatmentcode AS UA_TR_TREATMENTCODE,                         T.cellid        AS UA_TR_CELLID,                         T.rundatetime   AS UA_TR_RUNDATETIME         FROM    T,                 DL         WHERE  T.treatmentcode = DL.treatmentcode) TRT_CELLS WHERE  CH_CELLS.ua_ch_treatmentcode(+) = TRT_CELLS.ua_tr_treatmentcode;  The query has 2 DISTINCT subqueries.  The execution plan shows one with DISTICT Placement transformation applied and not the other.

• Web Services Example - Part 2: Programmatic

  - by Denis T

  In this edition of the ADF Mobile blog we'll tackle part 2 of our Web Service examples.  In this posting we'll take a look at using a SOAP Web Service but calling it programmatically in code and parsing the return into a bean. Getting the sample code: Just click here to download a zip of the entire project.  You can unzip it and load it into JDeveloper and deploy it either to iOS or Android.  Please follow the previous blog posts if you need help getting JDeveloper or ADF Mobile installed.  Note: This is a different workspace than WS-Part1 Defining our Web Service: Just like our first installment, we are using the same public weather forecast web service provided free by CDYNE Corporation.  Sometimes this service goes down so please ensure you know it's up before reporting this example isn't working. We're going to concentrate on the same two web service methods, GetCityForecastByZIP and GetWeatherInformation. Defing the Application: The application setup is identical to the Weather1 version.  There are some improvements to the data that is displayed as part of this example though.  Now we are able to show the associated image along with each forecast line when using the Forecast By Zip feature.  We've also added the temperature Hi/Low values into the UI. Summary of Fundamental Changes In This Application The most fundamental change is that we're binding the UI to the Bean Data Controls instead of directly to the Web Service Data Controls.  This gives us much more flexibility to control the shape of the data and allows us to do caching of the data outside of the Web Service.  This way if your application is, say offline, your bean could still populate with data from a local cache and still show you some UI as opposed to completely failing because you don't have any connectivity. In general we promote this type of programming technique with ADF Mobile to insulate your application from any issues with network connectivity. What's different with this example? We have setup the Web Service DC the same way but now we have managed beans to process the data.  The following classes define the "Model" of our application:  CityInformation-CityForecast-Forecast, WeatherInformation-WeatherDescription.  We use WeatherBean for UI interaction to the model layer.  If you look through this example, we don't really do that much with the java code except use it to grab the image URL from the weather description.  In a more realistic example, you might be using some JDBC classes to persist the data to a local database. To have a good architecture it is always good to keep your model and UI layers separate.  This gets muddied if you start to use bindings on a page invoked from Java code and this java code starts to become your "model" layer.  Since bindings are page specific, your model layer starts to become entwined with your UI.  Not good!  To help with this, we've added some utility functions that let you invoke DC methods without having a binding and thus execute methods from your "model" layer without requiring a binding in your page definition.  We do this with the invokeDataControlMethod of the AdfmfJavaUtilities class.  An example of this method call is available in line 95 of WeatherInformation.java and line 93 of CityInformation.Java. What's a GenericType? Because Web Service Data Controls (and also URL Data Controls AKA REST) use generic name/value pairs to define their structure and don't have strongly typed objects, these are actually stored internally as GenericType objects.  The GenericType class is simply a property map of name/value pairs that can be hierarchical.  There are methods like getAttribute where you supply the index of the attribute or it's string property name.  Why is this important to know?  Because invokeDataControlMethod returns GenericType objects and developers either need to parse these GenericType objects themselves or use one of our helper functions. GenericTypeBeanSerializationHelper This class does exactly what it's name implies.  It's a helper class for developers to aid in serialization of GenericTypes to/from java objects.  This is extremely handy if you have a large GenericType object with many attributes (or you're just lazy like me!) and you just want to parse it out into a real java object you can use more easily.  Here you would use the fromGenericType method.  This method takes the class of the Java object you wish to return and the GenericType as parameters.  The method then parses through each attribute in the GenericType and uses reflection to set that same attribute in the Java class.  Then the method returns that new object of the class you specified.  This is obviously very handy to avoid a lot of shuffling code between GenericType and your own Java classes.  The reverse method, toGenericType is also available when you want to go the other way.  In this case you supply the string that represents the package location in the DataControl definition (Example: "MyDC.myParams.MyCollection") and then pass in the Java object you have that holds the data and a GenericType is returned to you.  Again, it will use reflection to calculate the attributes that match between the java class and the GenericType and call the getters/setters on those. Issues and Possible Improvements: In the next installment we'll show you how to make your web service calls asynchronously so your UI will fill dynamically when the service call returns but in the meantime you show the data you have locally in your bean fed from some local cache.  This gives your users instant delivery of some data while you fetch other data in the background.

• Current State EA: Focus on the Integration!!!

  - by Eric A. Stephens

  A recent project has me at the front end of a large implementation effort covering multiple software components. In addition to the challenges of integrating 15-20 separate and new software components there is the challenge of integrating the portfolio into an existing environment. Like other clients I've worked with and other environments I've worked in for many years, this is typical. The applications are undocumented and under patched leading to a mystery for any architect leading change.  We can boil down most architecture development methodologies (ADM) into first understanding the current/baseline state and then envisioning one or more future states. Many pundits emphasize the need to focus on the future/target states. I agree since enterprise architecture (EA) is about where you are going and not so much where you have been. But to be effective in the future, I contend some focused time needs to be spent on the current state. And specifically on the integration. Integration is always the difficult part of a project (I might put it more coarsely at a cocktail party). While I don't have a case study, my anecdotal experience suggests poorly integrated application portfolios tend to cost more to operate and create entropy when trying to respond to new changes and opportunities. In the aforementioned project, I was able to get one of our EAs assigned to focus on just integration almost immediately. While we're still early in the process, this EA is uncovering all sorts of information that will greatly assist our future state planning for this solution. This information is driving early decision making that we anticipate will accelerate our efforts moving forward. #next_pages_container { width: 5px; hight: 5px; position: absolute; top: -100px; left: -100px; z-index: 2147483647 !important; } #next_pages_container { width: 5px; hight: 5px; position: absolute; top: -100px; left: -100px; z-index: 2147483647 !important; } #next_pages_container { width: 5px; hight: 5px; position: absolute; top: -100px; left: -100px; z-index: 2147483647 !important; } #next_pages_container { width: 5px; hight: 5px; position: absolute; top: -100px; left: -100px; z-index: 2147483647 !important; }

• hp XW8000 work station power supply

  - by user281745

  My power supply went up in the XW8000 and I bought a new corsair cx500. I installed it but when I hook it up and I turn the computer on I get a beeping noise from the computer. I looked at the old power supply and the new power supply. The only difference is that the new power supply has 500 watts and the old one is 450 watts and the old PSU has a brown wire and the new power supply has 2 orange wires at the end. I found out that it is a sense wire that is in a different location so I was wondering how do I fix this problem.

• Public Cloud, co-location and managed services ... what is the cloud?

  - by llaszews

  Recently I have had conversation with a number of people that are selling and implementing 'cloud' solutions. I put cloud in quotes as implementations like co-location (aka co-lo) and managed services (sometimes referred to as 'your mess for less') have become popular options for companies moving to the cloud. These are obviously not pure public cloud offerings and probably more of hybrid cloud implementations as the infrastructure (PasS and IaaS)is dedicated to a specific customer. This eliminates the security, multi-tenancy, performance and other concerns that companies have regarding public cloud. Are co-location and managed services cloud to you? Are they something your company is considering when you think about cloud ?

• Java Champion Dick Wall Explores the Virtues of Scala (otn interview)

  - by Janice J. Heiss

  In a new interview up on otn/java, titled “Java Champion Dick Wall on the Virtues of Scala (Part 2),” Dick Wall explains why, after a long career in programming exploring Lisp, C, C++, Python, and Java, he has finally settled on Scala as his language of choice. From the interview: “I was always on the lookout for a language that would give me both Python-like productivity and simplicity for just writing something and quickly having it work and that also offers strong performance, toolability, and type safety (all of which I like in Java). Scala is simply the first language that offers all those features in a package that suits me. Programming in Scala feels like programming in Python (if you can think it, you can do it), but with the benefit of having a compiler looking over your shoulder and telling you that you have the wrong type here or the wrong method name there.The final ‘aha!’ moment came about a year and a half ago. I had a quick task to complete, and I started writing it in Python (as I have for many years) but then realized that I could probably write it just as fast in Scala. I tried, and indeed I managed to write it just about as fast.”Wall makes the remarkable claim that once Java developers have learned to work in Scala, when they work on large projects, they typically find themselves more productive than they are in Java. “Of course,” he points out, “people are always going to argue about these claims, but I can put my hand over my heart and say that I am much more productive in Scala than I was in Java, and I see no reason why the many people I know using Scala wouldn’t say the same without some reason.”Read the interview here.

• Social Targeting: This One's Just for You

  - by Mike Stiles

  Think of social targeting in terms of the archery competition we just saw in the Olympics. If someone loaded up 5 arrows and shot them straight up into the air all at once, hoping some would land near the target, the world would have united in laughter. But sadly for hysterical YouTube video viewing, that’s not what happened. The archers sought to maximize every arrow by zeroing in on the spot that would bring them the most points. Marketers have always sought to do the same. But they can only work with the tools that are available. A firm grasp of the desired target does little good if the ad products aren’t there to deliver that target. On the social side, both Facebook and Twitter have taken steps to enhance targeting for marketers. And why not? As the demand to monetize only goes up, they’re quite motivated to leverage and deliver their incredible user bases in ways that make economic sense for advertisers. You could target keywords on Twitter with promoted accounts, and get promoted tweets into search. They would surface for your followers and some users that Twitter thought were like them. Now you can go beyond keywords and target Twitter users based on 350 interests in 25 categories. How does a user wind up in one of these categories? Twitter looks at that user’s tweets, they look at whom they follow, and they run data through some sort of Twitter secret sauce. The result is, you have a much clearer shot at Twitter users who are most likely to welcome and be responsive to your tweets. And beyond the 350 interests, you can also create custom segments that find users who resemble followers of whatever Twitter handle you give it. That means you can now use boring tweets to sell like a madman, right? Not quite. This ad product is still quality-based, meaning if you’re not putting out tweets that lead to interest and thus, engagement, that tweet will earn a low quality score and wind up costing you more under Twitter’s auction system to maintain. That means, as the old knight in “Indiana Jones and the Last Crusade” cautions, “choose wisely” when targeting based on these interests and categories to make sure your interests truly do line up with theirs. On the Facebook side, they’re rolling out ad targeting that uses email addresses, phone numbers, game and app developers’ user ID’s, and eventually addresses for you bigger brands. Why? Because you marketers asked for it. Here you were with this amazing customer list but no way to reach those same customers should they be on Facebook. Now you can find and communicate with customers you gathered outside of social, and use Facebook to do it. Fair to say such users are a sensible target and will be responsive to your message since they’ve already bought something from you. And no you’re not giving your customer info to Facebook. They’ll use something called “hashing” to make sure you don’t see Facebook user data (beyond email, phone number, address, or user ID), and Facebook can’t see your customer data. The end result, social becomes far more workable and more valuable to marketers when it delivers on the promise that made it so exciting in the first place. That promise is the ability to move past casting wide nets to the masses and toward concentrating marketing dollars efficiently on the targets most likely to yield results.

• What can be the cause of new bugs appearing somewhere else when a known bug is solved?

  - by MainMa

  During a discussion, one of my colleagues told that he has some difficulties with his current project while trying to solve bugs. "When I solve one bug, something else stops working elsewhere", he said. I started to think about how this could happen, but can't figure it out. I have sometimes similar problems when I am too tired/sleepy to do the work correctly and to have an overall view of the part of the code I was working on. Here, the problem seems to be for a few days or weeks, and is not related to the focus of my colleague. I can also imagine this problem arising on a very large project, very badly managed, where teammates don't have any idea of who does what, and what effect on other's work can have a change they are doing. This is not the case here neither: it's a rather small project with only one developer. It can also be an issue with old, badly maintained and never documented codebase, where the only developers who can really imagine the consequences of a change had left the company years ago. Here, the project just started, and the developer doesn't use anyone's codebase. So what can be the cause of such issue on a fresh, small-size codebase written by a single developer who stays focused on his work? What may help? Unit tests (there are none)? Proper architecture (I'm pretty sure that the codebase has no architecture at all and was written with no preliminary thinking), requiring the whole refactoring? Pair programming? Something else?

• Failed Project: When to call it?

  - by Dan Ray

  A few months ago my company found itself with its hands around a white-hot emergency of a project, and my entire team of six pulled basically a five week "crunch week". In the 48 hours before go-live, I worked 41 of them, two back to back all-nighters. Deep in the middle of that, I posted what has been my most successful question to date. During all that time there was never any talk of "failure". It was always "get it done, regardless of the pain." Now that the thing is over and we as an organization have had some time to sit back and take stock of what we learned, one question has occurred to me. I can't say I've ever taken part in a project that I'd say had "failed". Plenty that were late or over budget, some disastrously so, but I've always ended up delivering SOMETHING. Yet I hear about "failed IT projects" all the time. I'm wondering about people's experience with that. What were the parameters that defined "failure"? What was the context? In our case, we are a software shop with external clients. Does a project that's internal to a large corporation have more space to "fail"? When do you make that call? What happens when you do? I'm not at all convinced that doing what we did is a smart business move. It wasn't my call (I'm just a code monkey) but I'm wondering if it might have been better to cut our losses, say we're not delivering, and move on. I don't just say that due to the sting of the long hours--the company royally lost its shirt on the project, plus the intangible costs to the company in terms of employee morale and loyalty were large. Factor that against the PR hit of failing to deliver a high profile project like this one was... and I don't know what the right answer is.

• Expected time for an CakePHP MVC form/controller and db make up

  - by hephestos

  I would like to know, what is an average time for building a form in MVC pattern with for example CakePHP. I build 8 functions, two of them do custom queries, return json data, split them, expand them in a model in memory and delivers to the view. Those are three queries if you consider and an array to feed view for making some combo box. Why? all these, because I have data from json and I split them in order to make row of data like a table. Like that I changed a bit the edit.ctp but not a lot. And I created a javascript outside, with three functions. One collects data the other upon a change of a combo returnes the selected values, and does also some redirection flow. All this, in average how much time should it take ?

• The State of the Internet -- Retail Edition

  - by David Dorf

  Over at Business Insider, there's a great presentation on the State of the Internet done in the Mary Meeker style.  Its 138 slides so I took the liberty of condensing it down to the 15 slides that directly apply to the retail industry.  However, I strongly recommend looking at the entire deck when you have time.  And while you're at it, Business Insider just launched a retail portal that's dedicated to retail industry content.  Please check it out as well.  My take-aways are below after the slide show. &amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;quot;&amp;amp;amp;amp;gt;&amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;gt; [Source: Business Insider] Here are a few things I took away from the statistics: Facebook and Twitter are in their infancy.  While all retailers should have social programs, search is still the driver and therefore should receive the lions share of investment.  Facebook referrals are up 92% year-over-year, but Google still does 80% of the referrals. E-commerce continues to grow at breakneck speed, but in-store commerce is still king. Stores are not showrooms yet.  And social commerce pure-plays like Gilt and Groupon are tiny but worthy of some attention. There are more smartphones than PCs on the internet, and the disparity will continue to grow. PC growth will be flat and Tablet use will continue to grow. Mobile accounts for 12% of all internet traffic. A quarter of smartphone sales come from China, so anyone with a presence there better have a strong mobile strategy. 38% of people have used their smartphone to make a purchase, and many use their smartphones inside stores.  Smartphones are a critical consumer tool for shopping. Mobile is starting to drive significant traffic to e-commerce sites, especially tablets.  Tablet strategies are crucial for retailers. Mobile payments from the likes of Paypal and Square are growing quickly.  It will be interesting to see how NFC plays in this area. Mobile operating systems are losing market share to iOS and Android.  I wonder in Microsoft can finally make a dent? The internet is being dominated by mobile devices, and retailers had better have a strong mobile strategy to meet consumer demand.

• What to do when product range evolves and site name does not reflect this?

  - by nitbuntu

  Suppose, just as an example, I have a website with domain www.gifts-for-dogs.com.....but after a few years I start selling stuff for Cats and Fish. I may not keep enough of a range of products for these other type of pets yet, so can't justify changing the domain name and logo (to something like gifts-for-pets.com) just yet....but envisage that I eventually may have to in the not too distant future. What would be a good strategy here and what are the steps I would have to consider before making these changes?

When we checked, customer was manually entering the username and password, config.xml had the entries encrypted However when verified, customer had the boot.properties at the Servers/AdminServer/security folder and DomainName/security didn't have this file. Adding boot.properies fixed the issue. Regards Shailesh Dyade

• Accessing ADF Faces components that are read-only from JavaScript

  - by Frank Nimphius

  Almost as a note to myself and to justify the time I spent on analyzing aproblem, a quick note on what to watch out for when working trying to access read-only ADF Faces components from JavaScript.  Those who tried JavaScript in ADF Faces probably know that you need to ensure the ADF Faces component  is represented by a JavaScript object on the client. You do this either implicitly by adding an af:clientListener component (in case you want to listen for a component event) or explicitly by setting the ADF Faces component clientComponent property to true. For the use case I looked at in JDeveloper 11g R1 (11.1.1.7) I needed to make an output text component clickable to call a JavaScript function in response. Though I added the af:clientComponent tag to the component I recognized that it also needed the clientComponent property set to true. Though I remember this as not being required in 11.1.1.6, I like the new behavior as it helps preventing read-only components from firing client side events unless you tell it to do so by setting the clientComponent property to true. Note: As the time of writing, JDeveloper 11.1.1.7 is not publicly available and I put the note in this blog as a reminder in case you ever hit a similar challenge so you know what to do.

• Where Twitter Stands Heading Into 2013

  - by Mike Stiles

  As Twitter continued throughout 2012 to be a stage on which global politics and culture played itself out, the company itself underwent some adjustments that give us a good indication of what users and brands can expect from the platform in 2013. The power of the network did anything but fade. Celebrities continued to use it to connect one-on-one. Even the Pope signed on this year. It continued to fuel revolutions. It played an exponentially large factor in this US Presidential election. And around the world, the freedom to speak was challenged as users were fired, sued, sometimes even jailed for their tweets. Expect more of the same in 2013, as Twitter has entrenched itself, for individuals, causes and brands, as the fastest, easiest, most efficient way to message the masses so some measure of impact can come from it. It’s changed everything, and it’s not finished. These fun facts reveal the position of strength with which Twitter enters 2013: It now generates a billion tweets every 2.5 days It has 500 million+ users The average Twitter user has tweeted 307 times 32% of everyone using the Internet uses Twitter It’s expected to bring in $540 million in ad revenue by 2014 11 new accounts are created every second High-level Executive Summary: people love it, people use it, and they’re going to keep loving and using it. Whether or not outside developers love it is a different matter. 2012 marked a shift from welcoming the third party support that played at least some role in Twitter being so warmly embraced, to discouraging anything that replicates what Twitter can do itself…or plans to do itself. It’s not the open playground it once was. Now Twitter must spend 2013 proving it can innovate in-house and keep us just as entranced. Likewise, Twitter is distancing itself from Facebook. Images from the #1 platform’s Instagram don’t work on Twitter anymore, and Twitter’s rolling out their own photo filter product. Where the two have lived in a “plenty of room for everybody” symbiosis up to now, 2013 could see the giants ramping up a full-on rivalry. Twitter is exhibiting a deliberate strategy. Updates have centered on more visually appealing search results, and making finding and sharing content easier. Deals have been cut with some media entities so their content stands out. CEO Dick Costolo has said tweets aren’t the attraction, they’re what leads you to content. Twitter aims to be a key distributor of media and info. Add the addition of former News Corp. President Peter Chernin to the board, and their hashtag landing page experience for events, and their media behemoth ambitions get pretty clear. There are challenges ahead and Costolo has also laid those out; entry into China, figuring out how to have Twitter deliver both comprehensive and relevant, targeted experiences, and the visualization of big data. What does this mean for corporations? They can expect a more media-rich evolution and growing emphases on imagery. They can expect more opportunities to create great media content and leverage Twitter for its distribution. And they can expect new ways to surface in searches. Are brands diving in? 56% of customer tweets to companies get completely and totally ignored. Ugh. A study Twitter recently conducted with Compete shows people who see tweets from retailers are more likely to buy a product. And, the more retailer tweets they see, the more likely they are to purchase on the retail site. As more of those tweets point to engaging media content from the brand, the results should get even better. Twitter appears ready for 2013. Enterprise brands have some work to do. @mikestilesPhoto Stuart Miles, freedigitalphotos.net

• How to adopt scrum agile methodology for a small .Net team

  - by Thabo

  I am working on a small product based company developing .Net applications. There is a small team with 5-6 developers. I am a person responsible for planning everything. But my primary role is Software developer. Now our current project is very unstable because of poor organization. Today my boss called me and told to submit a report about required resources, appropriate methodology, required man power and their salary scales to make the current project success. I know I don’t have enough organization skills and I need to go deep in my programming skills. So I need to focus only in the development. So I can’t manage the project anymore. Now I am searching some other ways to make ongoing development success. My questions are What is the suitable agile methodology to my team? Is Scrum is suitable for above mentioned scenario? If we adopt Scrum, what we have to do next? (I think hiring new one to manage the project is more suitable. So we have to get Scrum master and some other developers.) Are there any resources (books, Blogs and etc) to get some tips and advices to solve this problem? If Scrum is not a suitable methodology for our scenario, what else can be more suitable methodology to adopt? Can anyone give a good solution for my problem?

  Currently I'm using UCK and trying to make Edubuntu 12.04.1 DVD launch installer on 256Mb RAM: How to install Edubuntu on a system with low memory (256 Mb)? I was reading release notes for 12.10 and noticed that Language packs have now been moved off from the live image to a pool on the disc. How can I move other packages correctly so they would be available to the live system and for installation without network access?

• Easiest Way To Implement "Slow Motion" and variable game speed in XNA?

  - by TerryB

  I have an XNA 4.0 game that I want to be able to switch into slow motion and back again to full speed every now and then. So if you kill an enemy the game switches into slow motion as they explode and then goes back to normal. What is the easiest way to do this in XNA 4.0 without having to alter all my existing code that relies on GameTime? I have some code that relies on the TotalGameTime, which will be wrong unless I get XNA to slow down. Is there anyway to avoid refactoring that code? Thanks!

• C++11 Tidbits: Decltype (Part 2, trailing return type)

  - by Paolo Carlini

  Following on from last tidbit showing how the decltype operator essentially queries the type of an expression, the second part of this overview discusses how decltype can be syntactically combined with auto (itself the subject of the March 2010 tidbit). This combination can be used to specify trailing return types, also known informally as "late specified return types". Leaving aside the technical jargon, a simple example from section 8.3.5 of the C++11 standard usefully introduces this month's topic. Let's consider a template function like: template <class T, class U> ??? foo(T t, U u) { return t + u; } The question is: what should replace the question marks? The problem is that we are dealing with a template, thus we don't know at the outset the types of T and U. Even if they were restricted to be arithmetic builtin types, non-trivial rules in C++ relate the type of the sum to the types of T and U. In the past - in the GNU C++ runtime library too - programmers used to address these situations by way of rather ugly tricks involving __typeof__ which now, with decltype, could be rewritten as: template <class T, class U> decltype((*(T*)0) + (*(U*)0)) foo(T t, U u) { return t + u; } Of course the latter is guaranteed to work only for builtin arithmetic types, eg, '0' must make sense. In short: it's a hack. On the other hand, in C++11 you can use auto: template <class T, class U> auto foo(T t, U u) -> decltype(t + u) { return t + u; } This is much better. It's generic and a construct fully supported by the language. Finally, let's see a real-life example directly taken from the C++11 runtime library as implemented in GCC: template<typename _IteratorL, typename _IteratorR> inline auto operator-(const reverse_iterator<_IteratorL>& __x, const reverse_iterator<_IteratorR>& __y) -> decltype(__y.base() - __x.base()) { return __y.base() - __x.base(); } By now it should appear be completely straightforward. The availability of trailing return types in C++11 allowed fixing a real bug in the C++98 implementation of this operator (and many similar ones). In GCC, C++98 mode, this operator is: template<typename _IteratorL, typename _IteratorR> inline typename reverse_iterator<_IteratorL>::difference_type operator-(const reverse_iterator<_IteratorL>& __x, const reverse_iterator<_IteratorR>& __y) { return __y.base() - __x.base(); } This was guaranteed to work well with heterogeneous reverse_iterator types only if difference_type was the same for both types.
