  • Customer retention - why most companies have it wrong

    - by Michel Adar
    At least in the US market it is quite common for service companies to offer an initially discounted price to new customers. While this may attract new customers and robe customers from competitors, it is my argument that it is a bad strategy for the company. This strategy gives an incentive to change companies and a disincentive to stay with the company. From the point of view of the customer, after 6 months of being a customer the company rewards the loyalty by raising the price. A better strategy would be to reward customers for staying with the company. For example, by lowering the cost by 5% every year (compound discount so it does never get to zero). This is a very rational thing to do for the company. Acquiring new customers and setting up their service is expensive, new customers also tend to use more of the common resources like customer service channels. It is probably true for most companies that the cost of providing service to a customer of 10 years is lower than providing the same service in the first year of a customer's tenure. It is only logical to pass these savings to the customer. From the customer point of view, the competition would have to offer something very attractive, whether in terms of price or service, in order for the customer to switch. Such a policy would give an advantage to the first mover, but would probably force the competitors to follow suit. Overall, I would expect that this would reduce the mobility in the market, increase loyalty, increase the investment of companies in loyal customers and ultimately, increase competition for providing a better service. Competitors may even try to break the scheme by offering customers the porting of their tenure, but that would not work that well because it would disenchant existing customers and would be costly, assuming that it is costlier to serve a customer through installation and first year. What do you think? Is this better than using "save offers" to retain flip-floppers?

  • I get "An error occurred while Windows was synchronizing with [name of time server]." when trying t

    - by ChrisF
    Prompted by the answers to this question I decided to give the Windows built in time synchronisation another go. However, no matter what time server I use I get this error: "An error occurred while Windows was synchronizing with [name of time server]." The help suggests the following as reasons for failure: You are not connected to the Internet. Establish an Internet connection before you attempt to synchronize your clock. Your personal or network firewall prevents clock synchronization. Most corporate and organizational firewalls will block time synchronization, as do some personal firewalls. Home users should read the firewall documentation for information about unblocking network time protocol (NTP). You should be able to synchronize your clock if you switch to Windows Firewall. The Internet time server is too busy or is temporarily unavailable. If this is the case, try synchronizing your clock later, or update it manually by double-clicking the clock on the taskbar. You can also try using a different time server. The time shown on your computer is too different from the current time on the Internet time server. Internet time servers might not synchronize your clock if your computer's time is off by more than 15 hours. To synchronize the time properly, ensure that the date and time settings are set close to your current time in the Date and Time Properties in Control Panel. Now the first reason is clearly wrong - I am connected to the internet. I can see the 2nd being the most likely cause. I have Sygate Personal Firewall running, but it normally asks if something it trying to connect for the first time. Does anyone know I can unblock the NTP protocol - or at least check if it is blocked?. I don't think it's #3 or #4 as I've tried a number of different servers including the one currently used by Atomic Clock Sync. Though if someone knows the address of a UK time server I can double check this.

  • Web reference problem on WCF

    - by kaivalya
    I have a WCF service which I am able to connect to from my web application and get data. I now added a web reference to this wcf project to a wsdl file that a shipping company provides. Intention is to get shipping quotes.. I am able to access the objects that are generated from this wsdl file but when I call service.Authenticate("DEMO"); method almost nothing happens. I debug and see the debugger continue to the next lines but there is no change on service parameters and service.isauthorized is null.. Can you lead me to how I should debug this further and things I should check, or if there are additional steps that I need to ensure to have a web reference working on wcf app Thanks using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel; using System.Text; using ShippingCalculator.com.freight.api; namespace ShippingCalculator { public class ShippingService : IShippingService { freight_service service = new freight_service(); public string GetData(int value) { service.setConnectionType(".net"); service.Authenticate("DEMO"); OriginRequest origin = new OriginRequest(); origin.zip = "60101"; DestinationRequest destination = new DestinationRequest(); destination.zip = "10001"; PackageRequest package = new PackageRequest(); package.weight = "10"; ShipmentInfoRequest shipmentInfo = new ShipmentInfoRequest(); shipmentInfo.ship_date = DateTime.Now.AddDays(5); service.setOrigin(origin); service.setDestination(destination); service.setPackage(package); service.setShipmentInfo(shipmentInfo); Quote quote = service.getQuote(); return string.Format("Quote Number: {0}<br /> ", quote.QuoteNumber); } } } using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using ShippingTestApp.ShippingServiceReference; namespace ShippingTestApp.Controllers { [HandleError] public class HomeController : Controller { public ActionResult Index() { ShippingServiceClient shipClient = new ShippingServiceClient(); shipClient.GetData(0); ViewData["Message"] = shipClient.GetData(0); return View(); } } }

  • Active Directory: User UPN or DN for NTLM name, using pure LDAP?

    - by Bernd Haug
    I have a Java app that can authenticate to LDAP by logging users into the AD LDAP server with the NTLM name (which they are used to - this is a requirement). I now also need to do authorization, and hence need to find a forest-unique identifier for the user (DN or UPN should work), from which I can further query the directory. The method needs to be absolutely portable, even if the AD is structured in an unusual fashion, otherwise I could just do a string replacement and search for a UPN of "${ntlm-user}@${ntlm-domain}.${configured-trailing-domain}" How can I do this, using pure LDAP? Currently, I'm using the java.naming.directory package, which I'd like to keep using, since it doesn't throw up problems when not binding with a DN but logging in with an NTLM name?

  • Declaring pointers; asterisk on the left or right of the space between the type and name?

    - by GenTiradentes
    I've seen mixed versions of this in a lot of code. (This applies to C and C++, by the way.) People seem to declare pointers in one of two ways, and I have no idea which one is correct, of if it even matters. The first way it to put the asterisk adjacent the type name, like so: someType* somePtr; The second way is to put the asterisk adjacent the name of the variable, like so: someType *somePtr; This has been driving me nuts for some time now. Is there any standard way of declaring pointers? Does it even matter how pointers are declared? I've used both declarations before, and I know that the compiler doesn't care which way it is. However, the fact that I've seen pointers declared in two different ways leads me to believe that there's a reason behind it. I'm curious if either method is more readable or logical in some way that I'm missing.

  • How to display specific data from a file

    - by user1067332
    My program is supposed to ask the user for firstname, lastname, and phone number till the users stops. Then when to display it asks for the first name and does a search in the text file to find all info with the same first name and display lastname and phones of the matches. import java.util.*; import java.io.*; import java.util.Scanner; public class WritePhoneList { public static void main(String[] args)throws IOException { BufferedWriter output = new BufferedWriter(new FileWriter(new File( "PhoneFile.txt"), true)); String name, lname, age; int pos,choice; try { do { Scanner input = new Scanner(System.in); System.out.print("Enter First name, last name, and phone number "); name = input.nextLine(); output.write(name); output.newLine(); System.out.print("Would you like to add another? yes(1)/no(2)"); choice = input.nextInt(); }while(choice == 1); output.close(); } catch(Exception e) { System.out.println("Message: " + e); } } } Here is the display code, when i search for a name, it finds a match but displays the last name and phone number of the same name 3 times, I want it to display all of the possible matches with the first name. import java.util.*; import java.io.*; import java.util.Scanner; public class DisplaySelectedNumbers { public static void main(String[] args)throws IOException { String name; String strLine; try { FileInputStream fstream = new FileInputStream("PhoneFile.txt"); // Get the object of DataInputStream DataInputStream in = new DataInputStream(fstream); BufferedReader br = new BufferedReader(new InputStreamReader(in)); Scanner input = new Scanner(System.in); System.out.print("Enter a first name"); name = input.nextLine(); strLine= br.readLine(); String[] line = strLine.split(" "); String part1 = line[0]; String part2 = line[1]; String part3 = line[2]; //Read File Line By Line while ((strLine= br.readLine()) != null) { if(name.equals(part1)) { // Print the content on the console System.out.print("\n" + part2 + " " + part3); } } }catch (Exception e) {//Catch exception if any System.out.println("Error: " + e.getMessage()); } } }

  • "The protocol 'net.msmq' is not supported."

    - by Randolpho St. John
    OMG, a new lesson! Will wonders never cease? So I ran into an interesting issue setting up a WCF service to consume an MSMQ queue. I won't bother you with the details of how to actually build a WCF/MSMQ service; there are plenty of tutorials on the subject. I want to share with you an interesting error that I ran into and the surprisingly simple fix. The error occurs when attempting to generate a Service Reference or even simply browsing to the WSDL of your WCF/MSMQ service in the form of a YSOD with the following error: "The protocol 'net.msmq' is not supported." After a lot of Googling on the subject turning up plenty of questions with the same error but no answers. So I went digging into some application level config files on a server that already had a WCF/MSMQ service successfully set up by the network admin, and the answer was amazingly simple: If you are hosting an MSMQ/WCF service in IIS, you have to tell IIS to allow net.msmq protocol. It's in the advanced settings for the application or site in which you are hosting the service. .... aaaand, that's it.

  • Use a preferred username but authenticate against Kerberos principal

    - by Jason R. Coombs
    What I desire to do should be pretty simple. I have an Ubuntu 10.04 box. It's currently configured to authenticate users against a kerberos realm (EXAMPLE.ORG). There is only one realm in the krb5.conf file and it is the default realm. [libdefaults] default_realm = EXAMPLE.ORG PAM is configured to use the pam_krb5 module, so if a user account is created on the local machine, and that username matches the [email protected] credential, that user may log in by supplying his kerberos password. What I would like to do instead is create a local user account with a different username, but have it always authenticate against the canonical name in the kerberos server. For example, the kerberos principal is [email protected]. I would like to create the local account preferred.name and somehow configure kerberos that when someone attempts to log in as preferred.name, it uses the principal [email protected]. I have tried using the auth_to_local_names in krb5.conf, but this doesn't seem to do the trick. [realms] EXAMPLE.ORG = { auth_to_local_names = { full.name = preferred.name } I have tried adding [email protected] to ~preferred.name/.k5login. In all cases, when I attempt to log in as preferred.name@host and enter the password for full.name, I get Access denied. I even tried using auth_to_local in krb5.conf, but I couldn't get the syntax right. Is it possible to have a (distinct) local username that for all purposes behaves exactly like a matching username does? If so, how is this done?

  • Xalan redirect:write , use either of two element values to create name of new .xml file depending on

    - by Bilzac
    So I have the following code: <redirect:write select="concat('..\\folder\\,string(filename),'.xml')"> Where "filename" is a tag in the xml source. My problem occurs when filename is null or blank. And this is the case for several of the xml filename tags. So what I am trying to implement is a checking method. This is what I have done: <xsl-if test = "filename != ''"> <xsl:variable name = "tempName" select = "filename" /> </xsl-if> <xsl-if test ="filename = ''"> <xsl:variable name = "tempName" select = "filenameB"/> </xsl-if> <redirect:write select="concat('..\\folder\\,string($tempName),'.xml')"> I seem to be getting NPEs when I compile my Java code, saying the Variable not resolvable: tempName

  • How to model has_many with polymorphism?

    - by Daniel Abrahamsson
    I've run into a situation that I am not quite sure how to model. Suppose I have a User class, and a user has many services. However, these services are quite different, for example a MailService and a BackupService, so single table inheritance won't do. Instead, I am thinking of using polymorphic associations together with an abstract base class: class User < ActiveRecord::Base has_many :services end class Service < ActiveRecord::Base validates_presence_of :user_id, :implementation_id, :implementation_type belongs_to :user belongs_to :implementation, :polymorphic = true delegate :common_service_method, :name, :to => :implementation end #Base class for service implementations class ServiceImplementation < ActiveRecord::Base validates_presence_of :user_id, :on => :create has_one :service, :as => :implementation has_one :user, :through => :service after_create :create_service_record #Tell Rails this class does not use a table. def self.abstract_class? true end #Default name implementation. def name self.class.name end protected #Sets up a service object def create_service_record service = Service.new(:user_id => user_id) service.implementation = self service.save! end end class MailService < ServiceImplementation #validations, etc... def common_service_method puts "MailService implementation of common service method" end end #Example usage MailService.create(..., :user_id => user.id) BackupService.create(...., :user_id => user.id) user.services.each do |s| puts "#{user.name} is using #{s.name}" end #Daniel is using MailService, Daniel is using BackupService So, is this the best solution? Or even a good one? How have you solved this kind of problem?

  • Singular method name for single object argument, plural for a list?

    - by nasufara
    I'm having a problem with naming a method for a database application. In my Database instance, I have a method that can remove an Agreement object from the database. However, I want to be able to remove multiple Agreements at once, to be able to use transactions. The problem is that I also have an overload to remove a single Agreement object. Essentially, my structure is like this: public class Database { // ... public void RemoveAgreement(Agreement a) { // ... } public void RemoveAgreement(IEnumerable<Agreement> agreements) { // ... } } But this can be confusing, as the overload with the list of Agreements has a singular name, despite being inherently plural. My question is, how should I structure this? Should I have two overloads with the name RemoveAgreement(), or RemoveAgreements()? Or should I use two separate methods, instead of overloads? Thanks.

    I have a large xml file which contents a lot of self-closed tags. How could remove all them by using XSLT. eg. <?xml version="1.0" encoding="utf-8" ?> <Persons> <Person> <Name>user1</Name> <Tel /> <Mobile>123</Mobile> </Person> <Person> <Name>user2</Name> <Tel>456</Tel> <Mobile /> </Person> <Person> <Name /> <Tel>123</Tel> <Mobile /> </Person> <Person> <Name>user4</Name> <Tel /> <Mobile /> </Person> </Persons> I'm expecting the result: <?xml version="1.0" encoding="utf-8" ?> <Persons> <Person> <Name>user1</Name> <Mobile>123</Mobile> </Person> <Person> <Name>user2</Name> <Tel>456</Tel> </Person> <Person> <Tel>123</Tel> </Person> <Person> <Name>user4</Name> </Person> </Persons> Note: there are thousands of different elements, how can I programmatically remove all the self-closed tags. Another question is how to remove the empty element such as <name></name> as well. Can anyone help me on this? Many thanks.

  • How to Resolve a Transformation Service with BRE that occurs after an Orchestration in an Itinerary?

    - by Maxime Labelle
    In trying to implement simple integration patterns with Biztalk ESB Toolkit 2.0, I'm facing a problem trying to resolve a Transformation Itinerary Service that occurs after an Orchestration. I'm using the BRE Resolver to execute rules that need to inspect the Context Message Type property to determine the appropriate map to use. However, once the message reaches the step in the Itinerary associated with the Transformation Service, the map fails to execute. From careful investigation, it appears that the message type is not supplied to the "Resolution" object that is used internally by the BRE resolver. Indeed, since the message leaving the preceding Orchestration is typed System.Xml.XmlDocument, the type of the message is "demoted" from the context. By tracking rules engine execution, I can observe that the type of the message is indeed lost when reaching the BRE resolver. The type of the message is empty, whereas the strongly-typed of the document is Microsoft.XLANGs.BaseTypes.Any. The Orchestration service that I use is taken straight from the samples that ship with ESB Toolkit 2.0. Is there a way to perform Context-Based BRE resolution after an Orchestration in an Itinerary?

  • How do you keep SOA DRY?

    - by TaylorOtwell
    In our organization, we've shifted to a more "service oriented architecture". To give an example, let's assume we need to retrieve a "Quote" object. This quote has a shipper, a consignee, phone numbers, contacts, email addresses, and other location information. In other words, a Quote object is made up of many other objects. So, it seems like it would make sense to make a "Quote Retrieval Service". In our situation, we've accomplished this by creating a .NET solution and writing the service. The service API looks something like this (in pseudo-code): Function GetQuote(String ID) Returns Quote So, so far so good. Now, when this service is consumed, to keep things "de-coupled", we are creating essentially a duplicate of the Quote object and mapping from the QuoteService version of the Quote into the consumer's version of the Quote. In many cases, these classes will have the exact same properties. So, if the Quote service is consumed by 5 other applications, we would have 6 definitions of what a "Quote" is. One for each consumer, and one for the service. This feels wrong. I thought code was supposed to be DRY, but it seems like our method of SOA is forcing us to create tons of duplicated class definitions. What are we doing wrong, or is the code duplication just a "necessary evil" of SOA?

  • Constituent Experience Counts In Public Sector

    - by Michael Seback
      Businesses and government organizations are operating in an era of the empowered customer where service  and communication channels are challenged every day.  Consumers in the private sector have high expectations from purchasing gifts online, reading reviews on social sites, and expecting the companies they do business with to know and reward them.   In the Public Sector, constituents also expect government organizations to provide consistent and timely service across agencies and touch points.  Examples include requesting critical city services, applying for social assistance or reviewing insurance plans for a health insurance exchange. If an individual does not receive the services they need at the right time and place, it can create a dire situation – involving housing, food or healthcare assistance. Government organizations need to deliver a fast, reliable and personalized experience to constituents. Look at a few recent statistics from a Government focused survey: How do you define good customer service? 70 % improved services, 48% shortest time to provide information, 44% shortest time to resolve complaints What are ways/opportunities to improve customer service? 69% increased collaboration across agencies and 41% increased customer service channels Are you using data collected to make informed decisionsto improve customer service efforts? 39% data collection is limited, not used to improve decision making Source: Re-Imagining Customer Service in Government, 2012 Click here to see the highlights.  Would you like to get started – read Eight Steps to great constituent experiences for government.

  • Missing parameter error after running MySql query

    - by annelie
    Hello, I'm completely new to MySql and haven't used SqlDataSource with UpdateParameters before, so I'm probably missing something very obvious. When trying to update a record, the update does happen but then throws an error saying "'id' parameter is missing at the statement".

  • Solving &ldquo;XmlSchemaException: The global element '&lt;elementName&gt;' has already been declare

    - by ChrisD
    I recently encountered this error when I attempted to consume a new hosted WCF service.  The service used the Request/Response model and had been properly decorated.  The response and request objects were marked as DataContracts and had a specified namespace.   My WCF service interface was marked as a ServiceContract and shared the namespace attribute value.   Everything should have been fine, right? [ServiceContract(Namespace = "http://schemas.myclient.com/09/12")] public interface IProductActivationService { [OperationContract] ActivateSoftwareResponse ActivateSoftware(ActivateSoftwareRequest request); } well, not exactly.  Apparently the WSDL generator was having an issue: System.Xml.Schema.XmlSchemaException: The global element 'http://schemas.myclient.com/09/12:ActivateSoftwareResponse' has already been declared. After digging I’ve found the problem; the WSDL generator has some reserved suffixes for its entities, including Response, Request, Solicit (see http://msdn.microsoft.com/en-us/library/ms731045.aspx).  The error message is actually the result of a naming conflict.  The WSDL generator uses the namespace of the service to build its reserved types.  The service contract and data contract share a namespace, which coupled with the response/request name suffixes I was using in my class names, resulted in the SchemaException. The Fix: Two options: Rename my data contract entities to use a non-reserved keyword suffix (i.e.  change ActivateSoftwareResponse to ActivateSoftwareResp). or; Change the namespace of the data contracts to differ from the service contract namespace. I chose option 2 and changed all my data contracts to use a “http://schemas.myclient.com/09/12/data” namespace value. This avoided a name collision and I was able to produce my WSDL and consume my service.

  • Exposing a service to external systems - How should I design the contract?

    - by Larsi
    Hi! I know this question is been asked before here but still I'm not sure what to select. My service will be called from many 3 party system in the enterprise. I'm almost sure the information the service will collect (MyBigClassWithAllInfo) will change during the products lifetime. Is it still a good idea to expose objects? This is basically what my two alternatives: [ServiceContract] public interface ICollectStuffService { [OperationContract] SetDataResponseMsg SetData(SetDataRequestMsg dataRequestMsg); } // Alternative 1: Put all data inside a xml file [DataContract] public class SetDataRequestMsg { [DataMember] public string Body { get; set; } [DataMember] public string OtherPropertiesThatMightBeHandy { get; set; } // ?? } // Alternative 2: Expose the objects [DataContract] public class SetDataRequestMsg { [DataMember] public Header Header { get; set; } [DataMember] public MyBigClassWithAllInfo ExposedObject { get; set; } } public class SetDataResponseMsg { [DataMember] public ServiceError Error { get; set; } } The xml file would look like this: <?xml version="1.0" encoding="utf-8"?> <Message>   <Header>     <InfoAboutTheSender>...</InfoAboutTheSender>   </Header>   <StuffToCollectWithAllTheInfo>   <stuff1>...</stuff1> </StuffToCollectWithAllTheInfo> </Message> Any thought on how this service should be implemented?
