• Activate first workbook after closing second one?

  - by user1830217

  Open workbook A. Code in A opens workbook B. B is now the active WB. Code in B ends with ThisWorkBook.Close B closes, so A appears. Problem is, I can't get ANY Activate events in WB A to fire automatically after WB B closes. But if I close WB B manually, using mouse to 'x' out the WB, or via the menus, then WB A triggers Activate events. Somehow using VBA to close WB B prevents WB A Activate events from triggering. Same results in Excel 97 and 2003 Am I missing something, or is there a workaround?? Thanks! John

• JComboBox to string

  - by gabrielle fregil

  I have a String array of names, and then I added it into an editable JComboBox. The user can either pick his/her name from the choices or just input his/her name if not in the choices. How do I put the user input into a new string variable? String [] chooseName = { Mark, John, Allison, Jessica }; JComboBox combo = new JComboBox (chooseName); combo.setEditable(true); String chosenName = /* how do i place what the user inputed here? */

• Are there predifined styles for making arrow buttons in windows phone 7?

  - by Micah

  I want to make some buttons in my app that look like the common round buttons with the arrows found all over the win 7 apps. Anyone know where I can find resources for these? UPDATE Here's a great tutorial on creating round buttons in WP7. This is exactly what I was trying to do, but I will use the images mentioned by John Gardner below: http://blogs.msdn.com/b/priozersk/archive/2010/08/13/creating-round-button-for-wp7-part-1.aspx http://blogs.msdn.com/b/priozersk/archive/2010/08/14/creating-round-image-button-for-wp7-part-1.aspx Thakns!

• Ruby: Parse Excel 95-2003 files?

  - by Larry K

  Is there a way to read Excel 97-2003 files from Ruby? Background I'm currently using the Ruby Gem parseexcel -- http://raa.ruby-lang.org/project/parseexcel/ But it is an old port of the perl module. It works fine, but the latest format it parses is Excel 95. And guess what? Excel 2007 will not produce the Excel 95 format. John McNamara has taken over duties as the maintainer for the Perl Excel parser, see http://search.cpan.org/~jmcnamara/Spreadsheet-ParseExcel-0.55/lib/Spreadsheet/ParseExcel.pm The current version will parse Excel 95-2003 files. But is there a port to Ruby? My other thought is to build some Ruby to Perl glue code to enable use of the Perl library itself from Ruby. Eg, see http://stackoverflow.com/questions/451636/whats-the-best-way-to-export-utf8-data-into-excel/620612#620612 (I think it would be much faster to write the glue code than to port the parser.) Thanks, Larry

• Hudson pipelines

  - by johnoc

  Hi Can anyone help with this problem? I have a test job, a downstream job and a join job. I only want the join job to run if the downstream job succeeds. If the test job fails and the downstream job succeeds I still want to run the join job. Anyone know of a plugin that can help here? The join plugin is not good enough because I can configure it to run join job when test AND downstream succeed, or run join regardless of either jobs success/failure. But not run join job ONLY if downstream succeeds. Why do I want to do it this way? I want to pipeline jobs together but only if a common "downstream" job succeeds. If it fails then I want the pipeline to "break". Many thanks John

• Jquery plugin for getting changes in textarea and sending them to server

  - by user763410

  I am getting a file "abc.txt" from server and dispaying it in a text area for editing. <div id="filecontents"> <textarea> CONTENTS OF FILE LARGER THAN 10KB </textarea> </div> The contents of the file are potentially large. The user will edit the textarea and add/delete text from any part(not just the end). I want to send ONLY the changes to the server for patching. How do I accomplish this?. Is there a javascript version of the popular linux command(diff). John Resig's diff code may not work as, for me, it will involve additional parsing on server side. Thanks!

• SELF-SOLVED AutoHotkey Function GetMouseTaskbutton need to adapt for 64-bit OS

  - by auntyEEK

  SOLVED VIA SELF-HELP, HAIR-PULLING, AND TEETH-GRINDING. THANKS ANYWAY....... I'm using the GetMouseTaskbutton function from this thread on AHK forum.

I'm using it in a routine to auto-activate window by hovering its taskbar button, and also a routine to close inactive window by middle-click on its taskbar button. Works great on my XP machine. The author had stated that the function does work in Vista, but it refuses to work for me in Vista 64-bit, so apparently it is only valid in 32-bit. And I am very new to AHK, and don't know how to adapt it. Unfortunately, my queries at the site sank without a trace. Does anyone have advice for me? I will be most grateful. Thanks.

• Windows 7 Phone Database – Querying with Views and Filters

  - by SeanMcAlinden

  I’ve just added a feature to Rapid Repository to greatly improve how the Windows 7 Phone Database is queried for performance (This is in the trunk not in Release V1.0). The main concept behind it is to create a View Model class which would have only the minimum data you need for a page. This View Model is then stored and retrieved rather than the whole list of entities. Another feature of the views is that they can be pre-filtered to even further improve performance when querying. You can download the source from the Microsoft Codeplex site http://rapidrepository.codeplex.com/. Setting up a view Lets say you have an entity that stores lots of data about a game result for example: GameScore entity public class GameScore : IRapidEntity {     public Guid Id { get; set; }     public string GamerId {get;set;}     public string Name { get; set; }     public Double Score { get; set; }     public Byte[] ThumbnailAvatar { get; set; }     public DateTime DateAdded { get; set; } }   On your page you want to display a list of scores but you only want to display the score and the date added, you create a View Model for displaying just those properties. GameScoreView public class GameScoreView : IRapidView {     public Guid Id { get; set; }     public Double Score { get; set; }     public DateTime DateAdded { get; set; } }   Now you have the view model, the first thing to do is set up the view at application start up. This is done using the following syntax. View Setup public MainPage() {     RapidRepository<GameScore>.AddView<GameScoreView>(x => new GameScoreView { DateAdded = x.DateAdded, Score = x.Score }); } As you can see, using a little bit of lambda syntax, you put in the code for constructing a single view, this is used internally for mapping an entity to a view. *Note* you do not need to map the Id property, this is done automatically, a view model id will always be the same as it’s corresponding entity.   Adding Filters One of the cool features of the view is that you can add filters to limit the amount of data stored in the view, this will dramatically improve performance. You can add multiple filters using the fluent syntax if required. In this example, lets say that you will only ever show the scores for the last 10 days, you could add a filter like the following: Add single filter public MainPage() {     RapidRepository<GameScore>.AddView<GameScoreView>(x => new GameScoreView { DateAdded = x.DateAdded, Score = x.Score })         .AddFilter(x => x.DateAdded > DateTime.Now.AddDays(-10)); } If you wanted to further limit the data, you could also say only scores above 100: Add multiple filters public MainPage() {     RapidRepository<GameScore>.AddView<GameScoreView>(x => new GameScoreView { DateAdded = x.DateAdded, Score = x.Score })         .AddFilter(x => x.DateAdded > DateTime.Now.AddDays(-10))         .AddFilter(x => x.Score > 100); }   Querying the view model So the important part is how to query the data. This is done using the repository, there is a method called Query which accepts the type of view as a generic parameter (you can have multiple View Model types per entity type) You can either use the result of the query method directly or perform further querying on the result is required. Querying the View public void DisplayScores() {     RapidRepository<GameScore> repository = new RapidRepository<GameScore>();     List<GameScoreView> scores = repository.Query<GameScoreView>();       // display logic } Further Filtering public void TodaysScores() {     RapidRepository<GameScore> repository = new RapidRepository<GameScore>();     List<GameScoreView> todaysScores = repository.Query<GameScoreView>().Where(x => x.DateAdded > DateTime.Now.AddDays(-1)).ToList();       // display logic }   Retrieving the actual entity Retrieving the actual entity can be done easily by using the GetById method on the repository. Say for example you allow the user to click on a specific score to get further information, you can use the Id populated in the returned View Model GameScoreView and use it directly on the repository to retrieve the full entity. Get Full Entity public void GetFullEntity(Guid gameScoreViewId) {     RapidRepository<GameScore> repository = new RapidRepository<GameScore>();     GameScore fullEntity = repository.GetById(gameScoreViewId);       // display logic } Synchronising The View If you are upgrading from Rapid Repository V1.0 and are likely to have data in the repository already, you will need to perform a synchronisation to ensure the views and entities are fully in sync. You can either do this as a one off during the application upgrade or if you are a little more cautious, you could run this at each application start up. Synchronise the view public void MyUpgradeTasks() {     RapidRepository<GameScore>.SynchroniseView<GameScoreView>(); } It’s worth noting that in normal operation, the view keeps itself in sync with the entities so this is only really required if you are upgrading from V1.0 to V2.0 when it gets released shortly.   Summary I really hope you like this feature, it will be great for performance and I believe supports good practice by promoting the use of View Models for specific pages. I’m hoping to produce a beta for this over the next few days, I just want to add some more tests and hopefully iron out any bugs. I would really appreciate any thoughts on this feature and would really love to know of any bugs you find. You can download the source from the following : http://rapidrepository.codeplex.com/ Kind Regards, Sean McAlinden.

• Creating a dynamic proxy generator with c# – Part 2 – Interceptor Design

  - by SeanMcAlinden

  Creating a dynamic proxy generator – Part 1 – Creating the Assembly builder, Module builder and caching mechanism For the latest code go to http://rapidioc.codeplex.com/ Before getting too involved in generating the proxy, I thought it would be worth while going through the intended design, this is important as the next step is to start creating the constructors for the proxy. Each proxy derives from a specified type The proxy has a corresponding constructor for each of the base type constructors The proxy has overrides for all methods and properties marked as Virtual on the base type For each overridden method, there is also a private method whose sole job is to call the base method. For each overridden method, a delegate is created whose sole job is to call the private method that calls the base method. The following class diagram shows the main classes and interfaces involved in the interception process. I’ll go through each of them to explain their place in the overall proxy.   IProxy Interface The proxy implements the IProxy interface for the sole purpose of adding custom interceptors. This allows the created proxy interface to be cast as an IProxy and then simply add Interceptors by calling it’s AddInterceptor method. This is done internally within the proxy building process so the consumer of the API doesn’t need knowledge of this. IInterceptor Interface The IInterceptor interface has one method: Handle. The handle method accepts a IMethodInvocation parameter which contains methods and data for handling method interception. Multiple classes that implement this interface can be added to the proxy. Each method override in the proxy calls the handle method rather than simply calling the base method. How the proxy fully works will be explained in the next section MethodInvocation. IMethodInvocation Interface & MethodInvocation class The MethodInvocation will contain one main method and multiple helper properties. Continue Method The method Continue() has two functions hidden away from the consumer. When Continue is called, if there are multiple Interceptors, the next Interceptors Handle method is called. If all Interceptors Handle methods have been called, the Continue method then calls the base class method. Properties The MethodInvocation will contain multiple helper properties including at least the following: Method Name (Read Only) Method Arguments (Read and Write) Method Argument Types (Read Only) Method Result (Read and Write) – this property remains null if the method return type is void Target Object (Read Only) Return Type (Read Only) DefaultInterceptor class The DefaultInterceptor class is a simple class that implements the IInterceptor interface. Here is the code: DefaultInterceptor namespace Rapid.DynamicProxy.Interception {     /// <summary>     /// Default interceptor for the proxy.     /// </summary>     /// <typeparam name="TBase">The base type.</typeparam>     public class DefaultInterceptor<TBase> : IInterceptor<TBase> where TBase : class     {         /// <summary>         /// Handles the specified method invocation.         /// </summary>         /// <param name="methodInvocation">The method invocation.</param>         public void Handle(IMethodInvocation<TBase> methodInvocation)         {             methodInvocation.Continue();         }     } } This is automatically created in the proxy and is the first interceptor that each method override calls. It’s sole function is to ensure that if no interceptors have been added, the base method is still called. Custom Interceptor Example A consumer of the Rapid.DynamicProxy API could create an interceptor for logging when the FirstName property of the User class is set. Just for illustration, I have also wrapped a transaction around the methodInvocation.Coninue() method. This means that any overriden methods within the user class will run within a transaction scope. MyInterceptor public class MyInterceptor : IInterceptor<User<int, IRepository>> {     public void Handle(IMethodInvocation<User<int, IRepository>> methodInvocation)     {         if (methodInvocation.Name == "set_FirstName")         {             Logger.Log("First name seting to: " + methodInvocation.Arguments[0]);         }         using (TransactionScope scope = new TransactionScope())         {             methodInvocation.Continue();         }         if (methodInvocation.Name == "set_FirstName")         {             Logger.Log("First name has been set to: " + methodInvocation.Arguments[0]);         }     } } Overridden Method Example To show a taster of what the overridden methods on the proxy would look like, the setter method for the property FirstName used in the above example would look something similar to the following (this is not real code but will look similar): set_FirstName public override void set_FirstName(string value) {     set_FirstNameBaseMethodDelegate callBase =         new set_FirstNameBaseMethodDelegate(this.set_FirstNameProxyGetBaseMethod);     object[] arguments = new object[] { value };     IMethodInvocation<User<IRepository>> methodInvocation =         new MethodInvocation<User<IRepository>>(this, callBase, "set_FirstName", arguments, interceptors);          this.Interceptors[0].Handle(methodInvocation); } As you can see, a delegate instance is created which calls to a private method on the class, the private method calls the base method and would look like the following: calls base setter private void set_FirstNameProxyGetBaseMethod(string value) {     base.set_FirstName(value); } The delegate is invoked when methodInvocation.Continue() is called within an interceptor. The set_FirstName parameters are loaded into an object array. The current instance, delegate, method name and method arguments are passed into the methodInvocation constructor (there will be more data not illustrated here passed in when created including method info, return types, argument types etc.) The DefaultInterceptor’s Handle method is called with the methodInvocation instance as it’s parameter. Obviously methods can have return values, ref and out parameters etc. in these cases the generated method override body will be slightly different from above. I’ll go into more detail on these aspects as we build them. Conclusion I hope this has been useful, I can’t guarantee that the proxy will look exactly like the above, but at the moment, this is pretty much what I intend to do. Always worth downloading the code at http://rapidioc.codeplex.com/ to see the latest. There will also be some tests that you can debug through to help see what’s going on. Cheers, Sean.

• JavaScript Data Binding Frameworks

  - by dwahlin

  Data binding is where it’s at now days when it comes to building client-centric Web applications. Developers experienced with desktop frameworks like WPF or web frameworks like ASP.NET, Silverlight, or others are used to being able to take model objects containing data and bind them to UI controls quickly and easily. When moving to client-side Web development the data binding story hasn’t been great since neither HTML nor JavaScript natively support data binding. This means that you have to write code to place data in a control and write code to extract it. Although it’s certainly feasible to do it from scratch (many of us have done it this way for years), it’s definitely tedious and not exactly the best solution when it comes to maintenance and re-use. Over the last few years several different script libraries have been released to simply the process of binding data to HTML controls. In fact, the subject of data binding is becoming so popular that it seems like a new script library is being released nearly every week. Many of the libraries provide MVC/MVVM pattern support in client-side JavaScript apps and some even integrate directly with server frameworks like Node.js. Here’s a quick list of a few of the available libraries that support data binding (if you like any others please add a comment and I’ll try to keep the list updated): AngularJS MVC framework for data binding (although closely follows the MVVM pattern). Backbone.js MVC framework with support for models, key/value binding, custom events, and more. Derby Provides a real-time environment that runs in the browser an in Node.js. The library supports data binding and templates. Ember Provides support for templates that automatically update as data changes. JsViews Data binding framework that provides “interactive data-driven views built on top of JsRender templates”. jQXB Expression Binder Lightweight jQuery plugin that supports bi-directional data binding support. KnockoutJS MVVM framework with robust support for data binding. For an excellent look at using KnockoutJS check out John Papa’s course on Pluralsight. Meteor End to end framework that uses Node.js on the server and provides support for data binding on  the client. Simpli5 JavaScript framework that provides support for two-way data binding. WinRT with HTML5/JavaScript If you’re building Windows 8 applications using HTML5 and JavaScript there’s built-in support for data binding in the WinJS library.   I won’t have time to write about each of these frameworks, but in the next post I’m going to talk about my (current) favorite when it comes to client-side JavaScript data binding libraries which is AngularJS. AngularJS provides an extremely clean way – in my opinion - to extend HTML syntax to support data binding while keeping model objects (the objects that hold the data) free from custom framework method calls or other weirdness. While I’m writing up the next post, feel free to visit the AngularJS developer guide if you’d like additional details about the API and want to get started using it.

• 2 Days of Share &amp; Point

  - by Mark Rackley

  Groovy man… SharePoint Saturday Ozarks is back for 2010, bigger and better than before. Join us for a far out time and learn more about SharePoint in one day than you could in a year from the man… Yes! SharePoint Saturday Ozarks is back! SharePoint Saturday Ozarks is the largest SharePoint conference in Arkansas, Southern Missouri, and the very north east tip of Oklahoma. Last year we had a great turn out with 20 speakers, 5 MVPs, and attendees coming from Arkansas, Texas, Oklahoma, Missouri, Kansas, Nebraska, Indiana, Ohio, Alabama, Michigan, and Washington. Hey Man… what’s SharePoint Saturday anyway? Sounds like a conspiracy man… Not to worry, SharePoint Saturday is not an arm of the government bent on mind control or any attempt what-so-ever to bring you down man. SharePoint Saturday is grass roots effort started by Michael Lotter (http://www.sharepointsaturday.org/pages/about.aspx). It is a FREE one day event where the best SharePoint speakers gather to present their love, hatred, and frustrations of SharePoint to those lucky individuals who attend. Lessons are learned, contacts are made, prizes are won, food is eaten, assorted beverages are consumed until wee hours of the morning. SharePoint Saturday started with just a few sporadic one day events here and there. However, over the past year SharePoint Saturday has exploded and it’s hard to find a weekend where there is NOT a SharePoint Saturday event happing in some corner of the globe. There are even occasions where there are two SharePoint Saturdays on the same day! Many people are pleasantly surprised at the caliber of speakers at these SharePoint Saturday events. For the most part, these speakers are more eloquent, practiced, and practical than those speakers you find at the major multi-day conferences. These guys aren’t even paid to speak.. they do it out of love man… SharePoint Saturday Ozarks 2009 Alumni We had a star studded cast last year with many returning this year! Just check out the fun that they had… John Ferringer – Admin rockstar… I can still sense the awesomeness   SharePoint poster children Mike Watson & Laura Rogers     Lori Gowin spreading the SharePoint Love Eric Shupps is a little bit country and a little bit rock and roll       Cathy Dew, Sean McDonough, and JD Wade relaxing between gigs Actually, you can see real photos from last year’s SharePoint Saturday ozarks here:  picasaweb.google.com/mrackley/SharePointSaturdayOzarks#    What’s new for SharePoint Saturday Ozarks 2010 SharePoint Saturday Ozarks 2010 will totally blow your mind man. We’re getting the band back to together with many returning speakers and few new faces. Joel Oleson will be speaking this year, maybe he’ll grace us with his song stylings. Sadly, once again, Andrew Connell will not be able to attend SharePoint Saturday Ozarks, however he did feel the need to show his support in his own way. Prizes this year currently include books, software, a Zune HD, and much more! Wait Man… You said 2 days? I thought it was a one day event? Correct you are my herbal smelling friend… SharePoint Saturday Ozarks 2010 will spread the love an additional day this year. The first day will be all about the SharePoint love, on day 2 we will be taking a leisurely float down the Buffalo National River for those interested in a truly unique experience (no banjos allowed please).   Here are the details: WHAT 4 – 5 hour float down the Buffalo National River WHEN & WHERE Sunday June 13th. We will be leaving at 10am from the Parking Lot of: Gordon’s Motel & Canoe Rental Old Highway 7 Jasper, AR 72641 (870) 446-5252 Jasper is about 30 minutes south of Harrison, AR on Highway 7 South. You are responsible for bumming a ride to/from Gordon’s Motel, but they will be shuttling us to/from the river and providing canoes and a boxed lunch. WHAT ELSE? The float trip is dependent on the weather of course, we won’t be floating down the river in a thunderstorm, however I planned SPS Ozarks around a time of year ideal for floating. We aren’t talking class 5 rapids here, you don’t need any real skill, but you need to be okay with possibly tipping your canoe over once or twice. You can bring your own assorted beverages with you, but glass containers are not allowed on the river. I suggest a small cooler with extra snacks and drinks. Also bring clothing you can get wet in (these SharePoint people can get ornery). HOW DO I SIGN UP? When you register for SharePoint Saturday Ozarks, you will have the option to also sign up for the float trip. Seats are limited though! If you do not intend to go, please do not take someone else’s place.  The cost for the float trip will be about $35 dollars per person (which you are responsible for unless we find a sponsor). The price includes shuttle to/from river, canoe, life jackets, paddles, and boxed lunch. Far out man… how do I register??? You can register for SharePoint Saturday Ozarks by going to http://spsozarks.eventbrite.com/ We are limited to 200 people for the conference and 50 people for the float trip, so register today before we are sold out. Lodging for SharePoint Saturday Ozarks will once again take place at the Hotel Seville: Annex Suites are available for $103.20 This is So Groovy.. How can I help? I’m glad you asked! We are still looking for a few sponsors and one or two more speakers. If you are interested please let me know!  You can find out more information at http://www.sharepointsaturday.org/ozarks Hey… wait a minute…. what exactly IS SharePoint man??? Come to SharePoint Saturday Ozarks and find out!!  See you guys there!

• Slides and Code from my Silverlight MVVM Talk at DevConnections

  - by dwahlin

  I had a great time at the DevConnections conference in Las Vegas this year where Visual Studio 2010 and Silverlight 4 were launched. While at the conference I had the opportunity to give a full-day Silverlight workshop as well as 4 different talks and met a lot of people developing applications in Silverlight. I also had a chance to appear on a live broadcast of Channel 9 with John Papa, Ward Bell and Shawn Wildermuth, record a video with Rick Strahl covering jQuery versus Silverlight and record a few podcasts on Silverlight and ASP.NET MVC 2.  It was a really busy 4 days but I had a lot of fun chatting with people and hearing about different business problems they were solving with ASP.NET and/or Silverlight. Thanks to everyone who attended my sessions and took the time to ask questions and stop by to talk one-on-one. One of the talks I gave covered the Model-View-ViewModel pattern and how it can be used to build architecturally sound applications. Topics covered in the talk included: Understanding the MVVM pattern Benefits of the MVVM pattern Creating a ViewModel class Implementing INotifyPropertyChanged in a ViewModelBase class Binding a ViewModel declaratively in XAML Binding a ViewModel with code ICommand and ButtonBase commanding support in Silverlight 4 Using InvokeCommandBehavior to handle additional commanding needs Working with ViewModels and Sample Data in Blend Messaging support with EventBus classes, EventAggregator and Messenger My personal take on code in a code-beside file (I’m all in favor of it when used appropriately for message boxes, child windows, animations, etc.) One of the samples I showed in the talk was intended to teach all of the concepts mentioned above while keeping things as simple as possible.  The sample demonstrates quite a few things you can do with Silverlight and the MVVM pattern so check it out and feel free to leave feedback about things you like, things you’d do differently or anything else. MVVM is simply a pattern, not a way of life so there are many different ways to implement it. If you’re new to the subject of MVVM check out the following resources. I wish this talk would’ve been recorded (especially since my live and canned demos all worked :-)) but these resources will help get you going quickly.

• Introducción a ENUM (E.164 Number Mapping)

  - by raul.goycoolea

  E.164 Number Mapping (ENUM o Enum) se diseñó para resolver la cuestión de como se pueden encontrar servicios de internet mediante un número telefónico, es decir cómo se pueden usar los los teléfonos, que solamente tienen 12 teclas, para acceder a servicios de Internet. La parte más básica de ENUM es por tanto la convergencia de las redes del STDP y la IP; ENUM hace que pueda haber una correspondencia entre un número telefónico y un identificador de Internet. En síntesis, Enum es un conjunto de protocolos para convertir números E.164 en URIs, y viceversa, de modo que el sistema de numeración E.164 tenga una función de correspondencia con las direcciones URI en Internet. Esta función es necesaria porque un número telefónico no tiene sentido en el mundo IP, ni una dirección IP tiene sentido en las redes telefónicas. Así, mediante esta técnica, las comunicaciones cuyo destino se marque con un número E.164, puedan terminar en el identificador correcto (número E.164 si termina en el STDP, o URI si termina en redes IP). La solución técnica de mirar en una base de datos cual es el identificador de destino tiene consecuencias muy interesantes, como que la llamada se pueda terminar donde desee el abonado llamado. Esta es una de las características que ofrece ENUM : el destino concreto, el terminal o terminales de terminación, no lo decide quien inicia la llamada o envía el mensaje sino la persona que es llamada o recibe el mensaje, que ha escrito sus preferencias en una base de datos. En otras palabras, el destinatario de la llamada decide cómo quiere ser contactado, tanto si lo que se le comunica es un email, o un sms, o telefax, o una llamada de voz. Cuando alguien quiera llamarle a usted, lo que tiene que hacer el llamante es seleccionar su nombre (el del llamado) en la libreta de direcciones del terminal o marcar su número ENUM. Una aplicación informática obtendrá de una base de datos los datos de contacto y disponibilidad que usted decidió. Y el mensaje le será remitido tal como usted especificó en dicha base de datos. Esto es algo nuevo que permite que usted, como persona llamada, defina sus preferencias de terminación para cualquier tipo de contenido. Por ejemplo, usted puede querer que todos los emails le sean enviados como sms o que los mensajes de voz se le remitan como emails; las comunicaciones ya no dependen de donde esté usted o deque tipo de terminal utiliza (teléfono, pda, internet). Además, con ENUM usted puede gestionar la portabilidad de sus números fijos y móviles. ENUM emplea una técnica de búsqueda indirecta en una base de datos que tiene los registros NAPTR ("Naming Authority Pointer Resource Records" tal como lo define el RFC 2915), y que utiliza el número telefónico Enum como clave de búsqueda, para obtener qué URIs corresponden a cada número telefónico. La base de datos que almacena estos registros es del tipo DNS.Si bien en uno de sus diversos usos sirve para facilitar las llamadas de usuarios de VoIP entre redes tradicionales del STDP y redes IP, debe tenerse en cuenta que ENUM no es una función de VoIP sino que es un mecanismo de conversión entre números/identificadores. Por tanto no debe ser confundido con el uso normal de enrutar las llamadas de VoIP mediante los protocolos SIP y H.323. ENUM puede ser muy útil para aquellas organizaciones que quieran tener normalizada la manera en que las aplicaciones acceden a los datos de comunicación de cada usuario. FundamentosPara que la convergencia entre el Sistema Telefónico Disponible al Público (STDP) y la Telefonía por Internet o Voz sobre IP (VoIP) y que el desarrollo de nuevos servicios multimedia tengan menos obstáculos, es fundamental que los usuarios puedan realizar sus llamadas tal como están acostumbrados a hacerlo, marcando números. Para eso, es preciso que haya un sistema universal de correspondencia de número a direcciones IP (y viceversa) y que las diferentes redes se puedan interconectar. Hay varias fórmulas que permiten que un número telefónico sirva para establecer comunicación con múltiples servicios. Una de estas fórmulas es el Electronic Number Mapping System ENUM, normalizado por el grupo de tareas especiales de ingeniería en Internet (IETF, Internet engineering task force), del que trata este artículo, que emplea la numeración E.164, los protocolos y la infraestructura telefónica para acceder indirectamente a diferentes servicios. Por tanto, se accede a un servicio mediante un identificador numérico universal: un número telefónico tradicional. ENUM permite comunicar las direcciones del mundo IP con las del mundo telefónico, y viceversa, sin problemas. Antes de entrar en mayores profundidades, conviene dar una breve pincelada para aclarar cómo se organiza la correspondencia entre números o URI. Para ello imaginemos una llamada que se inicia desde el servicio telefónico tradicional con destino a un número Enum. En ENUM Público, el abonado o usuario Enum a quien va destinada lallamada, habrá decidido incluir en la base de datos Enum uno o varios URI o números E.164, que forman una lista con sus preferencias para terminar la llamada. Y el sistema como se explica más adelante, elegirá cual es el número o URI adecuado para dicha terminación. Por tanto como resultado de la consulta a la base dedatos Enum siempre se da una relación unívoca entre el número Enum marcado y el de terminación, conforme a los deseos de la persona llamada.Variedades de ENUMUna posible fuente de confusión cuando se trata sobre ENUM es la variedad de soluciones o sistemas que emplean este calificativo. Lo habitual es que cuando se haga una referencia a ENUM se trate de uno de los siguientes casos: ENUM Público: Es la visión original de ENUM, como base de datos pública, parecida a un directorio, donde el abonado "opta" a ser incluido en la base de datos, que está gestionada en el dominio e164.arpa, delegando a cada país la gestión de la base de datos y la numeración. También se conoce como ENUM de usuario. Carrier ENUM, o ENUM Infraestructura, o de Operador: Cuando grupos de operadores proveedores de servicios de comunicaciones electrónicas acuerdan compartir la información de los abonados por medio de ENUM mediante acuerdos privados. En este caso son los operadores quienes controlan la información del abonado en vez de hacerlo (optar) los propios abonados. Carrier ENUM o ENUM de Operador también se conoce como Infrastructure ENUM o ENUM Infraestructura, y está siendo normalizado por IETF para la interconexión de VoIP (mediante acuerdos de peering). Como se explicará en la correspondiente sección, también se puede utilizar para la portabilidad o conservación de número. ENUM Privado: Un operador de telefonía o de VoIP, o un ISP, o un gran usuario, puede utilizar las técnicas de ENUM en sus redes y en las de sus clientes sin emplear DNS públicos, con DNS privados o internos. Resulta fácil imaginar como puede utilizarse esta técnica para que compañías multinacionales, o bancos, o agencias de viajes, tengan planes de numeración muy coherentes y eficaces. Cómo funciona ENUMPara conocer cómo funciona Enum, le remitimos a la página correspondiente a ENUM Público, puesto que esa variedad de Enum es la típica, la que dió lugar a todos los procedimientos y normas de IETF .Más detalles sobre: @page { margin: 0.79in } P { margin-bottom: 0.08in } H4 { margin-bottom: 0.08in } H4.ctl { font-family: "Lohit Hindi" } A:link { so-language: zxx } -- ENUM Público.

• E 2.0 Value Metaphors

  - by Tom Tonkin

  I guess I have been doing this too long. I can easily see the value of Enterprise 2.0 technology for an organization, but find it a challenge at times to convey that same value to others. I also know that I'm not the only one that has that issue. Others, that have that same passion, also suffer from being, perhaps, too close to the market. I was having this same discussion with a few colleagues when one of them suggested that metaphors might be a good vehicle to communicate the value to those that are not as familiar.  One such metaphor was discussed.Apparently,back in the early 50's, there was a great Air Force aviator and military strategist by the name of John Boyd.  Without going into a ton of detail (you can search him on the internet), what made Colonel Boyd great was that he never lost a dog fight.  As a matter of fact, they called him 'Forty-Second Boyd' since he claimed to be able to beat anyone in any type of aircraft in less than forty seconds, even if his aircraft was inferior to his opponents.His approach as was unique.  He observed over time that there was a pattern on how aviators  engaged in a dogfight.  He called this method OODA.   It describes how a person or, in our case, an organization, would react to an event.  OODA is an acrostic for Observation, Orientation, Decision and Action.  Again, there is a lot more on the internet about this.A pilot would go through this loop several times during a dogfight and Boyd would try to predict this loop and interrupt it by changing the landscape of the actual dogfight.  This would give Boyd an advantage and be able to predict what his opponent would do and then counterattack.Boyd went on to say that many companies have a similar reaction loop and that by understanding that loop, organizations would be able to adjust better to market conditions, predict what the competition is doing and reposition themselves to gain competitive advantages. So, our metaphor would be that Enterprise 2.0 provides companies greater visibility of their business by connecting to employees, customers and partners in a collaborative fashion.  This, in turn, helps them navigate through the tough times and provide lines of sight to more innovative ideas.  Innovation is that last tool for companies to achieve competitive advantage (maybe a discusion for another post).Perhaps this is more wordy than some other metaphor, but it does allow for an interesting  dialogue to start and maybe even a framwork to fullfill the promise of E 2.0. So, I'm sure there are many more metaphors for the value that E 2.0 brings to organzaitons. Do you have one to share? Please comment below and thanks for stopping by.

• Visiting the Emtel Data Centre

  Back in February at the first event of the Emtel Knowledge Series (EKS) I spoke to various people at Emtel about their data centre here on the island. I was trying to see whether it would be possible to arrange a meeting over there for a selected group of our community members. Well, let's say it like this... My first approach wasn't that promising and far from successful but during the following months there were more and more occasions to get in touch with the "right" contact persons at Emtel to make it happen... Setting up an appointment and pre-requisites The major improvement came during a Boot Camp for Windows Phone 8.1 App development organised by Microsoft Indian Ocean Islands in cooperation with Emtel at the Emtel World, Ebene. Apart from learning bits and pieces regarding Universal Apps I took the opportunity to get in touch with Arvin Lockee, Sales Executive - Data, during our lunch break. And this really kicked off the whole procedure. Prior to get access to the Emtel data centre it is requested that you provide full name and National ID of anyone going to visit. Also, it should be noted that there was only a limited amount of seats available. Anyways, packed with this information I posted through the usual social media channels. Responses came in very quickly and based on First-come, first-serve (FCFS) principle I noted down the details and forwarded them to Emtel in order to fix a date and time for the visit. In preparation on our side, all attendees exchanged contact details and we organised transport options to go to the data centre in Arsenal. The day before and on the day of our meeting, Arvin send me a reminder to check whether everything is still confirmed and ready to go... Of course, it was! Arriving at the Emtel Data Centre As I'm coming from Flic En Flac towards the North, we agreed that I'm going to pick up a couple of young fellows near the old post office in Port Louis. All went well, except that Sean eventually might be living in another time zone compared to the rest of us. Anyway, after some extended stop we were complete and arrived just in time in Arsenal to meet and greet with Ish and Veer. Again, Emtel is taking access procedures to their data centre very serious and the gate stayed close until all our IDs had been noted and compared to the list of registered attendees. Despite having a good laugh at the mixture of old and new ID cards it was a straight-forward processing. The ward was very helpful and guided us to the waiting area at the entrance section of the building. Shortly after we were welcomed by Kamlesh Bokhoree, the Data Centre Officer. He gave us brief introduction into the rules and regulations during our visit, like no photography allowed, not touching the buttons, and following his instructions through the whole visit. Of course! Inside the data centre Next, he explained us the multi-factor authentication system using a combination of bio-metric data, like finger print reader, and "classic" pin panel. The Emtel data centre provides multiple services and next to co-location for your own hardware they also offer storage options for your backup and archive data in their massive, fire-resistant vault. Very impressive to get to know about the considerations that have been done in choosing the right location and how to set up the whole premises. It should also be noted that there is 24/7 CCTV surveillance inside and outside the buildings. Strengths of the Emtel TIER 3 Data Centre, Mauritius Finally, we were guided into the first server room. And wow, the whole setup is cleverly planned and outlined in the architecture. From the false floor and ceilings in order to provide optimum air flow, over to the separation of cold and hot aisles between the full-size server racks, and of course the monitored air conditions in order to analyse and watch changes in temperature, smoke detection and other parameters. And not surprisingly everything has been implemented in two independent circuits. There is a standardised classification for the construction and operation of data centres world-wide, and the Emtel's one has been designed to be a TIER 4 building but due to the lack of an alternative power supplier on the island it is officially registered as a TIER 3 compliant data centre. Maybe in the long run there might be a second supplier of energy next to CEB... time will tell. Luckily, the data centre is integrated into the National Fibre Optic Gigabit Ring and Emtel already connects internationally through diverse undersea cable routes like SAFE & LION/LION2 out of Mauritius and through several other providers for onwards connectivity. The data centre is part of the National Fibre Optic Gigabit Ring and has redundant internet connectivity onwards. Meanwhile, Arvin managed to join our little group of geeks and he supported Kamlesh in answering our technical questions regarding the capacities and general operation of the data centre. Visiting the NOC and its dedicated team of IT professionals was surely one of the visual highlights. Seeing their wall of screens to monitor any kind of activities on the data lines, the managed servers and the activity in and around the building was great. Even though I'm using a multi-head setup since years I cannot keep it up with that setup... ;-) But I got a couple of ideas on how to improve my work spaces here at the office. Clear advantages of hosting your e-commerce and mobile backends locally After the completely isolated NOC area we continued our Q&A session with Kamlesh and Arvin in the second server room which is dedictated to shared environments. On first thought it should be well-noted that there is lots of space for full-sized racks and therefore co-location of your own hardware. Actually, given the feedback that there will be upcoming changes in prices the facilities at the Emtel data centre are getting more and more competitive and interesting for local companies, especially small and medium enterprises. After seeing this world-class infrastructure available on the island, I'm already considering of moving one of my root servers abroad to be co-located here on the island. This would provide an improved user experience in terms of site performance and latency. This would be a good improvement, especially for upcoming e-commerce solutions for two of my local clients. Later on, we actually started the conversation of additional services that could be a catalyst for the local market in order to attract more small and medium companies to take the data centre into their evaluations regarding online activities. Until today Emtel does not provide virtualised server environments but there might be ongoing plans in the future to cover this field as well. Emtel is a mobile operator and internet connectivity provider in the first place, entering a market of managed and virtualised server infrastructures including capacities in terms of cloud storage and computing are rather new and there is a continuous learning curve at Emtel, too. You cannot just jump into a new market and see how it works out... And I appreciate Emtel's approach towards a solid fundament and then building new services on top of that. Emtel as a future one-stop-shop service provider for all your internet and telecommunications needs. Emtel's promotional video about their TIER 3 data centre in Arsenal, Mauritius More details are thoroughly described in Emtel's brochure of their data centre. Check out their PDF document here. Thanks for this opportunity Visiting and walking through the Emtel data centre for more than 2 hours was a great experience. As representative of the Mauritius Software Craftsmanship Community (MSCC) I would like to thank anyone at Emtel involved in the process of making it happen, and especially to Arvin Lockee and Kamlesh Bokhoree for their time and patience in explaining the infrastructure and answering all the endless questions from our members. Thank You!

• Taking AIIM at Social

  - by Christie Flanagan

  Today we are pleased to have a guest post from Christian Finn (@cfinn).  Christian is Senior Director of Product Management for Oracle WebCenter and heads up the WebCenter evangelist team.Last week I had the privilege of speaking at AIIM’s new conference in San Francisco.  AIIM, for those of you not familiar with it, is a global community of information professionals and got its start with ECM and imaging long ago. With 65,000+ members, AIIM has now set about broadening its scope to focus more on the intersection between systems of record (think traditional ECM) and systems of engagement (think social solutions).  So AIIM’s conference is a natural place to be for WebCenter types like me, who have a foot in both of those worlds.AIIM used to have their name on a very large tradeshow, but have changed direction now to run a small, intimate conference.  The lineup of keynotes was terrific, including David Pogue of The New York Times, Clay Shirky, author of Here Comes Everybody, and Ted Schadler, author of Empowered among many thought-provoking and engaging speakers. (Note: Ted will soon be featured in our Social Business webcast series. Stay tuned.)John Mancini and his team at AIIM did a fabulous job running the event and the engagement from the 450 attendees was sustained over the two and a half days.  Our proudest moment was having three finalists up for AIIM awards including: San Joaquin County, CA, for a justice case management system using WebCenter Content and Oracle BPM; Medtronic and Fishbowl Solutions for their innovative iPad solutions on WebCenter Content, and the government of Louisville, Kentucky/Jefferson County for their accounts payable solution using WebCenter Content’s Image & Process Management.  The highlight of the awards night was San Joaquin winning the small organization award against some tough competition.In addition to the conversations sparked at the show, AIIM promoted the whitepapers their industry task forces have produced on the impact and opportunities created by systems of engagement and systems of record. The task forces were led by: Geoffrey Moore, the renowned high tech marketing guru and author of Crossing The Chasm; and Andrew McAfee, who coined the term and wrote the book, Enterprise 2.0. (Note: Andy will also be featured soon on the Social Business webcast series.)  These free papers make short, excellent reading and you can download them on the AIIM website: Moore highlights the changes to Enterprise IT that the social revolution will engender, and McAfee covers where and how organizations are finding value in using social techniques to foster innovation, to scale Q&A across the organization, and to connect sales and marketing for greater efficiency and effectiveness. Moore’s whitepaper is here and McAfee’s whitepapers are available here. For the benefit of those who did not get a chance to attend the AIIM conference, I’ll be posting the topics of my AIIM presentation, “Three Principles for Fixing Your Broken Organization,” here on the WebCenter blog over the rest of this week and next in a series of posts.

• The Minimalist Approach to Content Governance - Retire Phase

  - by Kellsey Ruppel

   Originally posted by John Brunswick. Good news - the Retire Phase is actually more fun than the Manage Phase. During the Retire Phase our content management team should not have to track down content creators if the Request Phase of this process was completed successfully. The ownership meta data, success criteria and time stamp that was applied to the original content submission will help to manage content at the end of the content life cycle. The Retire Phase will provide the opportunity for us to prune irrelevant content items through archiving or deletion, keeping the content system clear of irrelevant information, streamlining users ability to browse and search for content.   1. Act on Metrics Established during the Request Phase Why - Some information is only relevant for a given amount of time. In Content Platform Migration Strategy - Artifacts vs Perishable Content we examined two content types - Artifacts and Perishable content. Understanding the differences between Artifacts and Perishable content will allow us to explicitly respect their various lifespans. Additionally, some content may have been part of a project that failed to meet the success criteria outlined in the Request Phase. Any content that did not meet the metrics outlined in the Request Phase should be considered for deletion. How - Thankfully by adhering to to The Minimalist Approach to Content Governance our content should have some level of meta data associated with it that will allow us to quickly sort and understand how to deal with it. Content Management Systems like Oracle's Universal Content Management (UCM) natively allow you to create and save advanced searches that can use content meta data like folders, author, expiration date, security settings and custom meta data to pull back listings of content for examination. Additionally, analytics are available for all content items that allow us to determine if the usage is meeting success criteria that may have been previously outlined during the request phase. The lists that are produced from these approaches can be quickly reviewed for each project with the content owners and based on the nature of the content and success criteria undergo archiving or deletion. Impact - Retiring content that is no longer relevant will allow end users to have fast and relevant access to information across your enterprise. As we mentioned in our first post in this series - it is easy to quickly start producing content, but the challenge is ensuring that the environment is easy to navigate and use on the third week and during the third year. The light level of effort that was placed into the Request Phase of this process will set us up to keep content clean and relevant for a long time to come. With an up-to-date content repository users will be able to quickly find access to the information that is critical to their work processes. You might not get a holiday named in your honor managing the content system, but will appreciate their quick access to quality information.

• JavaFX 2.0 at Devoxx 2011

  - by Janice J. Heiss

  JavaFX Sessions Abound JavaFX had a big presence at Devoxx 2011 as witnessed by the number of sessions this year given by leading JavaFX movers and shakers.     “JavaFX 2.0 -- A Java Developer's Guide” by Java Champions Stephen Chin and Peter Pilgrim     “JavaFX 2.0 Hands On” by Jasper Potts and Richard Bair     “Animation Bringing your User Interfaces to Life” by Michael Heinrichs and John Yoong (JavaFX development team)     “Complete Guide to Writing Custom Bindings in JavaFX 2.0” by Michael Heinrichs (JavaFX development team)     “Java Rich Clients with JavaFX 2.0” by Jasper Potts and Richard Bair     “JavaFX Properties & Bindings for Experts” (and those who want to become experts) by Michael Heinrichs (JavaFX development team)     “JavaFX Under the Hood” by Richard Bair     “JavaFX Open Mic” with Jasper Potts and Richard Bair With the release of JavaFX 2.0 and Oracle’s move towards an open development model with an open bug database already created, it’s a great time for developers to take the JavaFX plunge. One Devoxx attendee, Mark Stephens, a developer at IDRsolutions blogged about a problem he was having setting up JavaFX on NetBeans to work on his Mac. He wrote: “I’ve tried desperate measures (I even read and reread the instructions) but it did not help. Luckily, I am at Devoxx at the moment and there seem to be a lot of JavaFX gurus here (and it is running on all their Macs). So I asked them… It turns out that sometimes the software does not automatically pickup the settings like it should do if you give it the JavaFX SDK path. The solution is actually really simple (isn’t it always once you know). Enter these values manually and it will work.” He simply entered certain values and his problem was solved. He thanked Java Champion Stephen Chin, “for a great talk at Devoxx and putting me out of my misery.” JavaFX in Java Magazine Over in the November/December 2011 issue of Java Magazine, Oracle’s Simon Ritter, well known for his creative Java inventions at JavaOne, has an article up titled “JavaFX and Swing Integration” in which he shows developers how to use the power of JavaFX to migrate Swing interfaces to JavaFX. The consensus among JavaFX experts is that JavaFX is the next step in the evolution of Java as a rich client platform. In the same issue Java Champion and JavaFX maven James Weaver has an article, “Using Transitions for Animation in JavaFX 2.0”. In addition, Oracle’s Vice President of Java Client Development, Nandini Ramani, provides the keys to unlock the mysteries of JavaFX 2.0 in her Java Magazine interview.

• The 2010 Life Insurance Conference - Washington, DC

  - by [email protected]

  How ironic to be in Washington, DC on April 15 - TAX DAY! Fortunately, I avoided IRS offices and attended the much more enjoyable 2010 Life Insurance Conference, presented by LIMRA, LOMA SOA and ACLI. This year's conference offered a variety of tracks focused on the Life Industry including Distribution/Marketing Marketing, Administration, Actuarial/Product Development, Regulatory, Reinsurance and Strategic Management. President and CEO of the ACLI, Frank Keating, opened the event by moderating a session titled "Executive Viewpoint on new Opportunities." Guest speakers included Ted Mathas, President and CEO of NY Life, and John Walters, President and CEO of Hartford Life. Both speakers were insightful as they shared the challenges and opportunities each company faces and the key role life insurance companies play in our society and the global economy. There were several key themes that were reiterated in multiple sessions throughout the conference - the economy is on the rebound, optimism is growing, consumer spending is up and an uptick in employment is likely to follow. The threat of a double dip recession has seemed to passed. Good news for our industry, and welcomed by all in attendance. Of special interest to me, given my background, was some research shared by both The Nolan Group and Novarica in separate sessions. Both firms indicate that policy administration upgrades/replacement projects remain a top priority in 2010. Carriers continue to invest in modern technology. Modern ultra-configurable systems enable carriers to switch from a waterfall to an agile project methodology, which often entails a "culture change" within an organization. Other themes heard throughout the two-day event: Virtually all sessions focused on People, Process and Technology! Product innovation, agility and speed to market are as important as ever. Social Networks and Twitter are becoming more popular ways of communicating with both field and dispersed staff. Several sessions focused on the application, new business and underwriting process. Companies continue looking for ways to increase market agility, accelerate speed to market, address cost issues and improve service levels across the process. They recognize the need to ease the way to do business with both producers and consumers. Author and economic futurist Jeff Thredgold presented an entertaining, informative and humorous general session on Wednesday afternoon that focused on the US and global economies, financial markets and retirement outlook. Thredgold did not disappoint anyone with his message! The Thursday morning general session was keynoted by Therese Vaughan (CEO - NAIC) and Thomas Crawford (President of C2 Group). Both speakers gave a poignant view of the recent financial crisis and discussed "Putting the Pieces Back Together." Therese spoke of the recent financial turmoil and likely changes to regulations to the financial services sector. Tom's topics focused on economic recovery and the political environment in Washington, and how that impacts our industry. Next year's event will be April 11-13, 2011 in Las Vegas. Roger A.Soppe, CLU, LUTCF, is the Senior Director of Insurance Strategy, Oracle Insurance.

• The Legend of the Filtered Index

  - by Johnm

  Once upon a time there was a big and bulky twenty-nine million row table. He tempestuously hoarded data like a maddened shopper amid a clearance sale. Despite his leviathan nature and eager appetite he loved to share his treasures. Multitudes from all around would embark upon an epiphanous journey to sample contents of his mythical purse of knowledge. After a long day of performing countless table scans the table was overcome with fatigue. After a short period of unavailability, he decided that he needed to consider a new way to share his prized possessions in a more efficient manner. Thus, a non-clustered index was born. She dutifully directed the pilgrims that sought the table's data - no longer would those despicable table scans darken the doorsteps of this quaint village. and yet, the table's veracious appetite did not wane. Any bit or byte that wondered near him was consumed with vigor. His columns and rows continued to expand beyond the expectations of even the most liberal estimation. As his rows grew grander they became more difficult to organize and maintain. The once bright and cheerful disposition of the non-clustered index began to dim. The wait time for those who sought the table's treasures began to increase. Some of those who came to nibble upon the banquet of knowledge even timed-out and never realized their aspired enlightenment. After a period of heart-wrenching introspection, the table decided to drop the index and attempt another solution. At the darkest hour of the table's desperation came a grand flash of light. As his eyes regained their vision there stood several creatures who looked very similar to his former, beloved, non-clustered index. They all spoke in unison as they introduced themselves: "Fear not, for we come to organize your data and direct those who seek to partake in it. We are the filtered index." Immediately, the filtered indexes began to scurry about. One took control of the past quarter's data. Another took control of the previous quarter's data. All of the remaining filtered indexes followed suit. As the nearly gluttonous habits of the table scaled forward more filtered indexes appeared. Regardless of the table's size, all of the eagerly awaiting data seekers were delivered data as quickly as a Jimmy John's sandwich. The table was moved to tears. All in the land of data rejoiced and all lived happily ever after, at least until the next data challenge crept from the fearsome cave of the unknown. The End.
