• Oracle RightNow CX for Good Customer Experiences

  - by Andreea Vaduva

  Oracle RightNow CX is all about the customer experience, it’s about understanding what drives a good interaction and it’s about delivering a solution which works for our customers and by extension, their customers. One of the early guiding principles of Oracle RightNow was an 8-point strategy to providing good customer experiences. Establish a knowledge foundation Empowering the customer Empower employees Offer multi-channel choice Listen to the customer Design seamless experiences Engage proactively Measure and improve continuously The application suite provides all of the tools necessary to deliver a rewarding, repeatable and measurable relationship between business and customer. The Knowledge Authoring tool provides gap analysis, WYSIWIG editing (and includes HTML rich content for non-developers), multi-level categorisation, permission based publishing and Web self-service publishing. Oracle RightNow Customer Portal, is a complete web application framework that enables businesses to control their own end-user page branding experience, which in turn will allow customers to self-serve. The Contact Centre Experience Designer builds a combination of workspaces, agent scripting and guided assistances into a Desktop Workflow. These present an agent with the tools they need, at the time they need them, providing even the newest and least experienced advisors with consistently accurate and efficient information, whilst guiding them through the complexities of internal business processes. Oracle RightNow provides access points for customers to feedback about specific knowledge articles or about the support site in general. The system will generate ‘incidents’ based on the scoring of the comments submitted. This makes it easy to view and respond to customer feedback. It is vital, more now than ever, not to under-estimate the power of the social web – Facebook, Twitter, YouTube – they have the ability to cause untold amounts of damage to businesses with a single post – witness musician Dave Carroll and his protest song on YouTube, posted in response to poor customer services from an American airline. The first day saw 150,000 views and is currently at 12,011,375. The Times reported that within 4 days of the post, the airline’s stock price fell by 10 percent, which represented a cost to shareholders of $180 million dollars. It is a universally acknowledged fact, that when customers are unhappy, they will not come back, and, generally speaking, it only takes one bad experience to lose a customer. The idea that customer loyalty can be regained by using social media channels was the subject of a 2011 Survey commissioned by RightNow and conducted by Harris Interactive. The survey discovered that 68% of customers who posted a negative review about a holiday on a social networking site received a response from the business. It further found that 33% subsequently posted a positive review and 34% removed the original negative review. Cloud Monitor provides the perfect mechanism for seeing what is being said about a business on public Facebook pages, Twitter or YouTube posts; it allows agents to respond proactively – either by creating an Oracle RightNow incident or by using the same channel as the original post. This leaves step 8 – Measuring and Improving: How does a business know whether it’s doing the right thing? How does it know if its customers are happy? How does it know if its staff are being productive? How does it know if its staff are being effective? Cue Oracle RightNow Analytics – fully integrated across the entire platform – Service, Marketing and Sales – there are in excess of 800 standard reports. If this were not enough, a large proportion of the database has been made available via the administration console, allowing users without any prior database experience to write their own reports, format them and schedule them for e-mail delivery to a distribution list. It handles the complexities of table joins, and allows for the manipulation of data with ease. Oracle RightNow believes strongly in the customer owning their solution, and to provide the best foundation for success, Oracle University can give you the RightNow knowledge and skills you need.

• Why Adobe Air is so underrated for building mobile apps?

  - by Marcelo de Assis

  I worked with Adobe Flash related technologies for the last 5 years, although not being a big fan of Adobe. I see some little bugs happening in some apps, but I cannot imagine why a lot of big companies do not even think to use use Adobe Air as a good technology for their mobile apps. I see a lot of mobile developer positions asking for experts in Android or iOS , but very much less positions asking for Adobe Air, even when Adobe Air apps have the advantage of being multi-plataform, with the same app working in Blackberry, iOS and Android. Is so much easier to develop a game using Flash, than using Android SDK, for example. It really have flaws (that I never saw) or it is just some kind of mass prejudgement? I also would like to hear what a project manager or a indie developer takes when choosing a plataform for building apps.

• Map Library: Client-side or Server-side?

  - by Mahdi

  As I have already asked here, I have to implement a Multi-Platform Map application. Now I have Mapstraction as an option which uses Javascript to implement the desired functionality. My question is, "Is there any reason/benefit to implement such a library (let say, Adapters) in Server-side (in my case, PHP)?" As these maps are all based on Javascript, there is a big reason to use Javascript again to make the adapter also, so it would not be dependent to PHP, Java, or .NET for example. But is that all? I wish to hear your ideas and comments also. :)

• What are the pro/cons of Unity3D as a choice to make games ?

  - by jokoon

  We are doing our school project with Unity3d, since they were using Shiva the previous year (which seems horrible to me), and I wanted to know your point of view for this tool. Pros: multi platform, I even heard Google is going to implement it in Chrome everything you need is here scripting languages makes it a good choice for people who are not programming gurus Cons: multiplayer ? proprietary, you are totally dependent of unity and its limit and can't extend it it's less "making a game from scratch" C++ would have been a cool thing I really think this kind of tool is interesting, but is it worth it to use at school for a project that involves more than 3 programming persons ? What do we really learn in term of programming from using this kind of tool (I'm ok with python and js, but I hate C#) ? We could have use Ogre instead, even if we were learning direct x starting january...

• APIs that deal with logins

  - by Brandon Still

  I have been asked to make a mobile app for a friends website. The website is a Multi level marketing site that sells products and franchises. A client logs in in to the website and can view his or her dashboard ( user can view team members, business volume, commissions, invoices, etc.) The app is supposed to bring the dashboard to user's mobile devices (w/ some added features). The company does not have any APIs that deal with interaction or authentication, and I am new to the whole secure login side of app development. My questions is this, how do I let the users gain access to their information via my app from the secure website when there is no API?

• Deploying a very simple application

  - by vanna

  I have a very simple working console application written in C++ linked with a light static library. It is just for testing purposes. Now that the coding part is done, I would like to know the process of actually deploying the program. I wrote a very basic CMakeLists.txt that create makefiles or VS projects to build the sources. I also have a program that calls the static library in order to make some google tests. To me, the distribution of this application goes like this : to developpers : the src directory with the CMakeLists.txt file (multi-platform distribution) with a README.txt and an INSTALL.txt to users : the executable and a README.txt git repo : everything mentionned above plus the sources for testing and the gtest external lib A this point : considering the complexity of my application, am I doing it right ? Is there any reference that would formalize this deployment process so I can get better and go further ? Say I would like to add dynamic libraries that can be updated, external libraries like boost : how should I package this to deploy it in a professionnal way ?

• Efficient existing rating system for multiplayer?

  - by Nikolay Kuznetsov

  I would like to add a rating for online version of a board game. In this game there are many game rooms each normally having 3-4 people. So I expect that player's rating adjustments (RA) should depends on Rating of opponents in the game room Number of players in game room and final place of a player Person gets rating increase if he plays more games and more frequently If a person leaves a game room (disconnect) before the game ends he should get punished with a high rating decrease I have found two related questions in here Developing an ELO like point system for a multiplayer gaming site Simplest most effective way to rank and measure player skill in a multi-player environment? Please, let me know what would be the most appropriate existing rating model to refer.

• concurrency::index<N> from amp.h

  - by Daniel Moth

  Overview C++ AMP introduces a new template class index<N>, where N can be any value greater than zero, that represents a unique point in N-dimensional space, e.g. if N=2 then an index<2> object represents a point in 2-dimensional space. This class is essentially a coordinate vector of N integers representing a position in space relative to the origin of that space. It is ordered from most-significant to least-significant (so, if the 2-dimensional space is rows and columns, the first component represents the rows). The underlying type is a signed 32-bit integer, and component values can be negative. The rank field returns N. Creating an index The default parameterless constructor returns an index with each dimension set to zero, e.g. index<3> idx; //represents point (0,0,0) An index can also be created from another index through the copy constructor or assignment, e.g. index<3> idx2(idx); //or index<3> idx2 = idx; To create an index representing something other than 0, you call its constructor as per the following 4-dimensional example: int temp[4] = {2,4,-2,0}; index<4> idx(temp); Note that there are convenience constructors (that don’t require an array argument) for creating index objects of rank 1, 2, and 3, since those are the most common dimensions used, e.g. index<1> idx(3); index<2> idx(3, 6); index<3> idx(3, 6, 12); Accessing the component values You can access each component using the familiar subscript operator, e.g. One-dimensional example: index<1> idx(4); int i = idx[0]; // i=4 Two-dimensional example: index<2> idx(4,5); int i = idx[0]; // i=4 int j = idx[1]; // j=5 Three-dimensional example: index<3> idx(4,5,6); int i = idx[0]; // i=4 int j = idx[1]; // j=5 int k = idx[2]; // k=6 Basic operations Once you have your multi-dimensional point represented in the index, you can now treat it as a single entity, including performing common operations between it and an integer (through operator overloading): -- (pre- and post- decrement), ++ (pre- and post- increment), %=, *=, /=, +=, -=,%, *, /, +, -. There are also operator overloads for operations between index objects, i.e. ==, !=, +=, -=, +, –. Here is an example (where no assertions are broken): index<2> idx_a; index<2> idx_b(0, 0); index<2> idx_c(6, 9); _ASSERT(idx_a.rank == 2); _ASSERT(idx_a == idx_b); _ASSERT(idx_a != idx_c); idx_a += 5; idx_a[1] += 3; idx_a++; _ASSERT(idx_a != idx_b); _ASSERT(idx_a == idx_c); idx_b = idx_b + 10; idx_b -= index<2>(4, 1); _ASSERT(idx_a == idx_b); Usage You'll most commonly use index<N> objects to index into data types that we'll cover in future posts (namely array and array_view). Also when we look at the new parallel_for_each function we'll see that an index<N> object is the single parameter to the lambda, representing the (multi-dimensional) thread index… In the next post we'll go beyond being able to represent an N-dimensional point in space, and we'll see how to define the N-dimensional space itself through the extent<N> class. Comments about this post by Daniel Moth welcome at the original blog.

• A Basic Thread

  - by Joe Mayo

  Most of the programs written are single-threaded, meaning that they run on the main execution thread. For various reasons such as performance, scalability, and/or responsiveness additional threads can be useful. .NET has extensive threading support, from the basic threads introduced in v1.0 to the Task Parallel Library (TPL) introduced in v4.0. To get started with threads, it's helpful to begin with the basics; starting a Thread. Why Do I Care? The scenario I'll use for needing to use a thread is writing to a file.  Sometimes, writing to a file takes a while and you don't want your user interface to lock up until the file write is done. In other words, you want the application to be responsive to the user. How Would I Go About It? The solution is to launch a new thread that performs the file write, allowing the main thread to return to the user right away.  Whenever the file writing thread completes, it will let the user know.  In the meantime, the user is free to interact with the program for other tasks. The following examples demonstrate how to do this. Show Me the Code? The code we'll use to work with threads is in the System.Threading namespace, so you'll need the following using directive at the top of the file: using System.Threading; When you run code on a thread, the code is specified via a method.  Here's the code that will execute on the thread: private static void WriteFile() { Thread.Sleep(1000); Console.WriteLine("File Written."); } The call to Thread.Sleep(1000) delays thread execution. The parameter is specified in milliseconds, and 1000 means that this will cause the program to sleep for approximately 1 second.  This method happens to be static, but that's just part of this example, which you'll see is launched from the static Main method.  A thread could be instance or static.  Notice that the method does not have parameters and does not have a return type. As you know, the way to refer to a method is via a delegate.  There is a delegate named ThreadStart in System.Threading that refers to a method without parameters or return type, shown below: ThreadStart fileWriterHandlerDelegate = new ThreadStart(WriteFile); I'll show you the whole program below, but the ThreadStart instance above goes in the Main method. The thread uses the ThreadStart instance, fileWriterHandlerDelegate, to specify the method to execute on the thread: Thread fileWriter = new Thread(fileWriterHandlerDelegate); As shown above, the argument type for the Thread constructor is the ThreadStart delegate type. The fileWriterHandlerDelegate argument is an instance of the ThreadStart delegate type. This creates an instance of a thread and what code will execute, but the new thread instance, fileWriter, isn't running yet. You have to explicitly start it, like this: fileWriter.Start(); Now, the code in the WriteFile method is executing on a separate thread. Meanwhile, the main thread that started the fileWriter thread continues on it's own.  You have two threads running at the same time. Okay, I'm Starting to Get Glassy Eyed. How Does it All Fit Together? The example below is the whole program, pulling all the previous bits together. It's followed by its output and an explanation. using System; using System.Threading; namespace BasicThread { class Program { static void Main() { ThreadStart fileWriterHandlerDelegate = new ThreadStart(WriteFile); Thread fileWriter = new Thread(fileWriterHandlerDelegate); Console.WriteLine("Starting FileWriter"); fileWriter.Start(); Console.WriteLine("Called FileWriter"); Console.ReadKey(); } private static void WriteFile() { Thread.Sleep(1000); Console.WriteLine("File Written"); } } } And here's the output: Starting FileWriter Called FileWriter File Written So, Why are the Printouts Backwards? The output above corresponds to Console.Writeline statements in the program, with the second and third seemingly reversed. In a single-threaded program, "File Written" would print before "Called FileWriter". However, this is a multi-threaded (2 or more threads) program.  In multi-threading, you can't make any assumptions about when a given thread will run.  In this case, I added the Sleep statement to the WriteFile method to greatly increase the chances that the message from the main thread will print first. Without the Thread.Sleep, you could run this on a system with multiple cores and/or multiple processors and potentially get different results each time. Interesting Tangent but What Should I Get Out of All This? Going back to the main point, launching the WriteFile method on a separate thread made the program more responsive.  The file writing logic ran for a while, but the main thread returned to the user, as demonstrated by the print out of "Called FileWriter".  When the file write finished, it let the user know via another print statement. This was a very efficient use of CPU resources that made for a more pleasant user experience. Joe

• How can I set a time limit for a game?

  - by Haoda Fu

  I am learning the multi-threading and timer in C# now. But it seems I can't find a good solution. For example, I would like to see how many addition problems that I can solve within 1 min. I would like my program to have A digital clock to count for 60 seconds in the top of my Console. Print a math problem in the middle of my console wait for my input. When 60 seconds is done, stop the math problem challenges immediately (most of time, it is still waiting for my input, but we will stop it immediately). Count how many correct problems that I have solved. Two challenges of the program now. a) how can we make sure the print time and math problem do not mess up. b) how can we stop the math challenges part immediately after time is up
