Uróboros [1093]

de System Administrator - domingo, 15 de febrero de 2015, 13:22
 

Uróboros

El uróboros (también ouroboros o uroboros) (del griego «ουροβóρος», "uróvoro", a su vez de oyrá, "cola", y borá, "alimento") es un símbolo que muestra a un animal serpentiforme que engulle su propia cola y que conforma, con su cuerpo, una forma circular. El uróboros simboliza el ciclo eterno de las cosas, también el esfuerzo eterno, la lucha eterna o bien el esfuerzo inútil, ya que el ciclo vuelve a comenzar a pesar de las acciones para impedirlo.

Uróboros o uroboros. En la iconografía alquímica el color verde se asocia con el principio mientras que el rojo simboliza la consumación del objetivo del Magnum Opus (la Gran Obra).

Xilografía de un uróboros de Lucas Jennis.

El uróboros es un concepto empleado en diversas culturas a lo largo de al menos los últimos 3000 años. Engloba varios conceptos similares y otros que no están relacionados y han sido asimilados recientemente por el cine y la televisión. Generalmente un dragón representado con su cola en la boca, devorándose a sí mismo. Representa la naturaleza cíclica de las cosas, el eterno retorno y otros conceptos percibidos como ciclos que comienzan de nuevo en cuanto concluyen (véase el mito de Sísifo). En un sentido más general simboliza el tiempo y la continuidad de la vida. Se usa como representación del renacimiento de las cosas que nunca desaparecen, solo cambian eternamente.

  • En un principio su uso más antiguo estaba en la emblemática serpiente del Antiguo Egipto y la Antigua Grecia. Los uróboros se remontan a los jeroglíficos hallados en la cámara del sarcófago de la pirámide de Unis, en el 2300 a. C. El símbolo tradicional consiste en un dragón o una serpiente que se muerde la cola y crea un círculo sin fin.
  • Igualmente se puede encontrar un mito similar en la mitología nórdica. En esta mitología, la serpiente Jormungand llegó a crecer tanto que pudo rodear el mundo y apresarse su propia cola con los dientes. Este mito fue divulgado más ampliamente por la literatura de entre guerras del siglo XX. El deseo por la consecución del saber oculto, llegar a encarar las fuerzas elementales de la naturaleza, temibles y monstruosas, pero que finalmente conducen hacia la debilidad y la culpa.
  • El uróboros representa la personificación de fenómenos naturales como el sol, las olas del mar, etc., que suben hasta cierta altura y caen luego bruscamente, para volver a empezar. Esto se relaciona con el mito solar de Sísifo y Helio, el disco del sol que sale cada mañana y después se hunde bajo el horizonte. Sísifo fue obligado a empujar una piedra enorme cuesta arriba por una ladera empinada, pero antes que alcanzase la cima de la colina, la piedra rodaba de nuevo hacia abajo, y Sísifo tenía que empezar nuevamente desde el principio.

Eternidad

 

Personificación de la Eternidad, sosteniendo el UróborosCariátide en el ábside de la Catedral de Milán (1611).

El concepto de eternidad (del latín aeternitas), relacionado con el de inmortalidad, se refiere, popularmente, unas veces a una duración infinita y sin límites, y otras designa una existencia sin tiempo o fuera del tiempo. Sin embargo, los conceptos de "eternidad", "inmortalidad" e "infinitud", al ahondarse más específicamente en su estudio particular, no poseen, de hecho, los mismos significados.

Existen diversas argumentaciones acerca del tópico de la eternidad, a través de las cuales, quienes las sustentan, empezando por el filósofo griego Aristóteles, tratan de demostrar que la materia, el movimiento y el tiempo deben haber existido y existirán eternamente.

Vulture Culture

  

Vulture Culture es el octavo álbum de The Alan Parsons Project, lanzado en 1985 por Arista Records. Siguiendo con el sello estilístico propio de la banda, el disco incluye una mezcla de canciones pop rock accesibles, contrastadas con otras de corte más progresivo y climático, aunque la música de Parsons fue virando hacia el sonido FM a lo largo de los 80s, no obstante la calidad musical se mantuvo intacta. El single principal "Let's Talk About Me" alcanzó el "Top 40" alemán, y el álbum tuvo muy buena acogida en Europa continental, aunque la recepción en los EE.UU. fue tibia, sin embargo aún llegó a ser certificado "oro".

Vulture Culture (la cultura del buitre) estuvo originalmente pensado para ser el disco dos en un álbum doble, del cual Ammonia Avenue iba a ser el disco uno, finalmente ambos fueron editados por separado. La portada muestra una suerte de pulsera metálica representando un uróboros devorando su propia cola, alegoría que -entre otros conceptos- simbolizaba el devenir cíclico de las cosas, aunque en este caso el reptil tiene cabeza de buitre.

Uruguay: The Economist’s country of the year [343]

de System Administrator - martes, 7 de enero de 2014, 15:56
 

The Economist’s country of the year (2013)

 Uruguay

Earth’s got talent

Resilient Ireland, booming South Sudan, tumultuous Turkey: our country of the year is…

HUMAN life isn’t all bad, but it sometimes feels that way. Good news is no news: the headlines mostly tell of strife and bail-outs, failure and folly.

Yet, like every year, 2013 has witnessed glory as well as calamity. When the time comes for year-end accountings, both the accomplishments and the cock-ups tend to be judged the offspring of lone egomaniacs or saints, rather than the joint efforts that characterise most human endeavour. To redress the balance from the individual to the collective, and from gloom to cheer, The Economist has decided, for the first time, to nominate a country of the year.

But how to choose it? Readers might expect our materialistic outlook to point us to simple measures of economic performance, but they can be misleading. Focusing on GDP growth would lead us to opt for South Sudan, which will probably notch up a stonking 30% increase in 2013—more the consequence of a 55% drop the previous year, caused by the closure of its only oil pipeline as a result of its divorce from Sudan, than a reason for optimism about a troubled land. Or we might choose a nation that has endured economic trials and lived to tell the tale. Ireland has come through its bail-out and cuts with exemplary fortitude and calm; Estonia has the lowest level of debt in the European Union. But we worry that this econometric method would confirm the worst caricatures of us as flint-hearted number-crunchers; and not every triumph shows up in a country’s balance of payments.

Another problem is whether to evaluate governments or their people. In some cases their merits are inversely proportional: consider Ukraine, with its thuggish president, Viktor Yanukovych, and its plucky citizens, freezing for democracy in the streets of Kiev, even though nine years ago they went to the trouble of having a revolution to keep the same man out of office. Or remember Turkey, where tens of thousands protested against the creeping autocracy and Islamism of Recep Tayyip Erdogan, the prime minister-cum-sultan. Alas, neither movement has yet been all that successful.

Definitional questions creep in, too. One possible candidate, Somaliland, has kept both piracy and Islamic extremism at bay, yet on most reckonings it is not a country at all, rather a renegade province of Somalia—which has struggled to contain either. As well as countries yet to be, we might celebrate one that could soon disintegrate: the United Kingdom, which hasn’t fared too badly, all things considered, since coming into being in 1707, but could fracture in 2014 should the Scots be foolhardy enough to vote for secession.

And the winner is

When other publications conduct this sort of exercise, but for individuals, they generally reward impact rather than virtue. Thus they end up nominating the likes of Vladimir Putin, Ayatollah Khomeini or, in 1938, Adolf Hitler. Adapting that realpolitikal rationale, we might choose Bashar Assad’s Syria, from which millions of benighted refugees have now been scattered to freezing camps across the Levant. If we were swayed by influence per head of population, we might plump for the Senkaku (or Diaoyu) islands, the clutch of barren rocks in the East China Sea that have periodically threatened to incite a third world war—though that might imply their independence, leading both China and Japan to invade us. Alternatively, applying the Hippocratic principle to statecraft, we might suggest a country from which no reports of harm or excitement have emanated. Kiribati seems to have had a quiet year.

 Mujica y Aerosmith

But the accomplishments that most deserve commendation, we think, are path-breaking reforms that do not merely improve a single nation but, if emulated, might benefit the world. Gay marriage is one such border-crossing policy, which has increased the global sum of human happiness at no financial cost. Several countries have implemented it in 2013—including Uruguay, which also, uniquely, passed a law to legalise and regulate the production, sale and consumption of cannabis. This is a change so obviously sensible, squeezing out the crooks and allowing the authorities to concentrate on graver crimes, that no other country has made it. If others followed suit, and other narcotics were included, the damage such drugs wreak on the world would be drastically reduced.

Better yet, the man at the top, President José Mujica, is admirably self-effacing. With unusual frankness for a politician, he referred to the new law as an experiment. He lives in a humble cottage, drives himself to work in a Volkswagen Beetle and flies economy class. Modest yet bold, liberal and fun-loving, Uruguay is our country of the year. ¡Felicitaciones!

 Ushuaia   

Ushuaia es una ciudad argentina, capital de la Provincia de Tierra del Fuego, Antártida e Islas del Atlántico Sur. Fue fundada el 12 de octubre de 1884 por Augusto Lasserre y se ubica en las costas delcanal Beagle rodeada por la cadena montañosa del Martial, en la bahía de Ushuaia. Además de ser un centro administrativo, es un nodo industrial, portuario y turístico. Es la única ciudad argentina que se encuentra del otro lado de los Andes, vista desde el resto del país.

Ushuaia

También es, de acuerdo a la clasificación de los mares de la Organización Hidrográfica Internacional, la única ciudad argentina (y puerto) con costas y aguas pertenecientes al Pacífico, si bien esto no es reconocido abiertamente por el estado argentino, que formalmente considera al canal Beagle un paso bioceánico, pues de otro modo contradiría tratados limítrofes firmados con Chile los cuales se lo impiden.

Ushuaia

Ushuaia suele ser llamada con el eslogan de «la ciudad más austral del mundo».

Using Cortana to interact with customers [1363]

Using Cortana to interact with customers

by Clint Rutkas

This week’s theme in our Windows 10 by 10 development series is extending customer engagement using the Windows 10 without your users even entering your app. Last week’s topic, Live Tiles and notifications showed how one way to extend your app’s experience, now let’s show how to use the Windows 10 personal assistant, Cortana, to do so. To illustrate what you can do with Cortana, we’ll be using the AdventureWorks sample on GitHub as our base for the code snippets below in this blog post.

In this blog post, we’ll talk about what Cortana is, how to make Cortana have a meaningful conversation with your customer, the initial work needed to get Cortana integrated into your app, and then two of the many ways your app could interact with your end user depending on the scenario.

 

What exactly is Cortana?

One of the neatest capabilities introduced in Windows 10 is the Cortana personal assistant, who joins us from Windows Phone. Cortana is a front and center experience in Windows 10 that users can engage with via natural language. With Cortana, users can engage with Windows (both the core OS, but also apps such as yours) the same way they would speak to a person. For example, think about the questions that only your app can answer to the user using Cortana’s voice such as “When is my next trip?”, “Search for a radio station”, “Is Jack online?”. Your app can then answer these questions by providing the answer for Cortana to say and display. Think about tasks that the user can ask Cortana to do in your app such as: “Cancel my trip to London”, “Like this station”, “Tell Jack I’m running late”.

Voice commands can provide quick access to info inside the app when you use voice command as deep links into your application. Just as you currently create a tile to provide a shortcut into your app, you can also use a voice command to serve as a shortcut to a screen inside your app. And just as you give the user the ability to pin that recent trip they created in your app onto their Start screen, you can also enable that same user to use a voice command in the Cortana experience to get them to that same trip. This ability can make your users more productive, and your app’s experience more accessible to them.

By extending Cortana, you can engage and delight your users by empowering them to get things done with a quick voice command. This blog post isn’t on the customer features of Cortana however, it is about how you can integrate it into your app.

Hey Cortana, let’s have a conversation

Since interacting with Cortana is speech based, your user experience needs to flow as if you were having a natural conversation with them. There are general Cortana design guidelines on MSDN that explain best practices for user interactions. For successful Cortana interactions, follow these principles as well: efficient, relevant, clear and trustworthy interactions.

What do they actually mean?

  • Efficient: Less is more. Be concise and use as few words as possible without losing meaning
  • Relevant: Keep the topic on track. If I request my favorite ABBA song be added to my playlist, don’t tell me my battery is low as well. Instead, confirm to me I’ll be rocking out to ABBA shortly :)
  • Clear: Write the conversation for your audience. Be sure the dialogue uses everyday language instead of jargon that few people may know.
  • Trustworthy: Responses should accurately represent what is happening and respect user preferences. If your app hasn’t completed a task, don’t say it has. And don’t return dialog that someone may not want to hear out loud

 

Also, you should consider localizing your Cortana interactions, especially if you’ve already localized the rest of your app or are making it available globally. Cortana is currently available in the US, UK, China, France, Italy, Germany and Spain, with more markets coming on board in the future. Localizing and adapting the interactions will aid in encouraging your customers to use the Cortana feature of your app.

Teaching Cortana what to respond to

Cortana uses a Voice Command Definition (VCD) file to define the speech interactions the user can have with your app. This file can be XML based or generated via code. Once your app runs for the first time, the command sets in the VCD will be installed. Here is a quick sample VCD:

<?xml version="1.0" encoding="utf-8"?>
  <CommandSet xml:lang="en-us" Name="AdventureWorksCommandSet_en-us">
    <CommandPrefix> Adventure Works, </CommandPrefix>
    <Example> Show trip to London </Example>
 
    <Command Name="showTripToDestination">
      <Example> show trip to London </Example>
      <ListenFor RequireAppName="BeforeOrAfterPhrase"> show trip to {destination} </ListenFor>
      <Feedback> Showing trip to {destination} </Feedback>
      <Navigate/>
    </Command>
 
    <PhraseList Label="destination">
      <Item> London </Item>
      <Item> Dallas </Item>
    </PhraseList>
 
  </CommandSet>
<!-- Other CommandSets for other languages -->
</VoiceCommands>

 

When your app is activated, InstallCommandSetsFromStorageFileAsync should be called in the OnLaunched app event handler to register the commands that Cortana should listen for. Keep in mind that if a device backup is restored and your app is reinstalled, voice command data is not preserved. To ensure the voice command data for your app stays intact, consider initializing your VCD file each time your app launches or activates. You can also store a setting that indicates if the VCD is currently installed, then check that setting each time your app launches or activates. Here is some basic code to get the VCD loaded into your app:

 

1
2
3
var storageFile = await Windows.Storage.StorageFile.GetFileFromApplicationUriAsync(new Uri("ms-appx:///CortanaVcd.xml"));
 
await Windows.ApplicationModel.VoiceCommands.VoiceCommandDefinitionManager.InstallCommandSetsFromStorageFileAsync(storageFile);

Being dynamic

Now that we have the grammar initialized, we can dynamically alter it at runtime. Here is a simple example of dynamically altering the VCD we loaded above:

1
2
3
4
5
6
7
private Windows.ApplicationModel.VoiceCommands.VoiceCommnadDefinition.VoiceCommandSet commandSetEnUs;
 
if (Windows.ApplicationModel.VoiceCommands.VoiceCommandDefinitionManager.InstalledCommandSets.TryGetValue("AdventureWorksCommandSet_en-us", out commandSetEnUs))
{
  // this code will fully replace the destination list
  await commandSetEnUs.SetPhraseListAsync("destination", new string[] {"Chicago", "Seattle", "New York", "Phoenix"});
}

How should my app interact with Cortana?

There are a number of ways for your app to interact with Cortana. The three most typical ways are:

  1. Have Cortana launch your app. Along with launching your app to the foreground, you can specify a deep link for an action or command to execute within the app.
  2. Within Cortana, allow simple user interaction for your app to store or return data in the background.
  3. Within Cortana, let your app and user interact with each other.

Launching your app to the foreground

If you have a complex task and want the user to jump directly into your app, using Cortana is a great solution. Since some complex tasks can actually be done faster and more accurately by voice commands, this may be the way to go.

  {

  }
 
  var commandArgs = e as Windows.ApplicationModel.Activation.VoiceCommandActivatedEventArgs;
  var navigationParameterString = "";
 
  Windows.ApplicationModel.VoiceCommands.VoiceCommand.SpeechRecognitionResult speechRecognitionResult = commandArgs.Result;
 
  // Get the name of the voice command and the text spoken
  string voiceCommandName = speechRecognitionResult.RulePath[0];
  string textSpoken = speechRecognitionResult.Text;
 
  // The commandMode is either "voice" or "text", and it indicates how the voice command was entered by the user.
  // Apps should respect "text" mode by providing feedback in a silent form.
  string commandMode = this.SemanticInterpretation("commandMode", speechRecognitionResult);
 
  switch (voiceCommandName)
  {
    case "showTripToDestination":
      // Access the value of the {destination} phrase in the voice command
      string destination = speechRecognitionResult.SemanticInterpretation.Properties["destination"][0];
 
      // Create a navigation parameter string to pass to the page
      navigationParameterString = string.Format("{0}|{1}|{2}|{3}",
                    voiceCommandName, commandMode, textSpoken, destination);
 
      // Set the page where to navigate for this voice command
      navigateToPageType = typeof(TripPage);
    break;
 
    default:
      // There is no match for the voice command name. Navigate to MainPage
      navigateToPageType = typeof(MainPage);
      break;
  }
 
  if (this.rootFrame == null)
  {
    // App needs to create a new Frame, not shown
  }
 
  if (!this.rootFrame.Navigate(navigateToPageType, navigationParameterString))
  {
    throw new Exception("Failed to create voice command page");
  }
}

Simple interaction to store or return data to/from your app within Cortana

Now that you have Cortana connected to your VCD and executing basic interactions, we’ll dive into having Cortana do some of the heavier lifting. For example, you can have Cortana provide data back to the user, or store some data. MSDN has a comprehensive walkthrough for setting up a background app for Cortana. Here’s a quick summary of the steps.

  1. Create a Windows Runtime Component project in your solution.
  2. Create a new class that implements the IBackgroundTask interface, which will serve as our app service.
  3. In your UWP app’s Package.appxmanifest, add a new Extension for the new app service. The MSDN documentation goes through this step in detail.

Here is a sample of what the Package.appxmanifest XML will look like:

 

1
2
3
4
5
6
7
8
9
10
11
12
13
<Package>
  <Applications>
    <Application>
      <Extensions>
        <Extension Category="windows.appService"
          EntryPoint=
            "AdventureWorks.VoiceCommands.AdventureWorksVoiceCommandService">
          <AppService Name="AdventureWorksVoiceCommandService"/>
        </Extension>
      </Extensions>
    <Application>
  <Applications>
</Package>

 

Once launched, the app background service has 0.5 seconds to call ReportSuccessAsync. Cortana uses the data provided by the app to show and verbalize the feedback specified in the VCD file. If the app takes longer than 0.5 seconds to return from the call, Cortana inserts a hand-off screen, as shown below. Cortana displays the hand-off screen until the application calls ReportSuccessAsync, or for up to 5 seconds. If the app service doesn’t call ReportSuccessAsync, or any of the VoiceCommandServiceConnection methods that provide Cortana with information, the user receives an error message and the app service call is cancelled.

 

Here is the basic code needed for the IBackgroundTask implementation to act as an app service:

namespace AdventureWorks.VoiceCommands
{
  public sealed class AdventureWorksVoiceCommandService : IBackgroundTask
  {
    public void Run(IBackgroundTaskInstance taskInstance)
    {
      BackgroundTaskDeferral _deferral = taskInstance.GetDeferral();
 
      //
      // TODO: Insert code
      //
      _deferral.Complete();
    }
  }
}

Having user interactions within Cortana

Now that you know the basics, you’re ready for richer user interactions within Cortana. The app can specify different types of screens to support functionality that includes:

  • Successful completion
  • Hand-off
  • Progress
  • Confirmation
  • Disambiguation
  • Error

Let’s dive into one of these scenarios above: disambiguation. There are times where your app will have multiple choices to return. Your app then needs to disambiguate what to do next. If the user was picking music and they could pick between ABBA, Nickelback or White Snake for their favorite band to play next, Cortana can handle this. The code below from the Adventure Works sample will show you how to handle disambiguation from within your app service,:

// Create a VoiceCommandUserMessage for the initial question.
var userPrompt = new VoiceCommandUserMessage();
userPrompt.DisplayMessage = "Which one do you want to cancel?";
userPrompt.SpokenMessage = "Which Chicago trip do you wanna cancel?";
// Create a VoiceCommandUserMessage for the second question,
// in case Cortana needs to reprompt.
var userReprompt = new VoiceCommandUserMessage();
userReprompt.DisplayMessage = “Which one did you want to cancel?”;
userReprompt.SpokenMessage = "Which one did you wanna to cancel?";
 
// Create the list of content tiles to show the selection items.
var destinationsContentTiles = new List<VoiceCommandContentTile>();
 
// create your VoiceCommandContentTiles
for(int i=0; i < 5; i++)
{
  var destinationTile = new VoiceCommandContentTile();
  destinationTile.ContentTileType = VoiceCommandContentTileType.TitleWith68x68IconAndText;
   
  // The AppContext is optional.
  // Replace this value with something specific to your app.
  destinationTile.AppContext = "id_Vegas_00" + i;
  destinationTile.Title = "Tech Conference";
 
  destinationTile.TextLine1 = "May " + i + "th";
 
  destinationsContentTiles.Add(destinationTile);
}
 
// Create the disambiguation response.
var response = VoiceCommandResponse.CreateResponseForPrompt(userPrompt, userReprompt, destinationsContentTiles);
 
// Request that Cortana shows the disambiguation screen.
var voiceCommandDisambiguationResult = await voiceServiceConnection.RequestDisambiguationAsync(response);
 
if (voiceCommandDisambiguationResult != null)
{
   // Use the voiceCommandDisambiguationResult.SelectedItem to take action.
   // Call Cortana to present the next screen in .5 seconds
   // and avoid a transition screen.
}

Wrapping up Cortana for now

We hope that you now better understand how Cortana can easily be added to your application, opening up a multitude of interaction models with your customers. From launching your app, all the way to a complex interaction without them even launching the app, Cortana integration really does add to user engagement. We hope that you thought about how your app could take advantage of Cortana’s extensibility – even if it’s simply providing a new way of deeply linking into your app experience.

If you feel Cortana makes sense for your apps, definitely take advantage of it. And once your updated app is submitted, be sure to redeem the “Adding Cortana to your app” DVLUP challenge, so you can claim points and XP for updating your apps. Also, let us know via @WindowsDev and #Win10x10 – we love to hear what developers are building on Windows.

Also, check out the full Windows 10 by 10 development series schedule for the topics we will be covering in the series. For more on Cortana, check back here in a couple weeks as we dive into using Cortana’s natural language capabilities in your app to deliver a more personal user experience.

Vehicle-to-Vehicle communication (V2V communication)

Posted by: Margaret Rouse

Vehicle-to-vehicle communication (V2V communication) is the wireless transmission of databetween motor vehicles.

The goal of V2V communication is to prevent accidents by allowing vehicles in transit to send position and speed data to one another over an ad hoc mesh network. Depending upon how the technology is implemented, the vehicle's driver may simply receive a warning should there be a risk of an accident or the vehicle itself may take preemptive actions such as braking to slow down.

 

V2V communication is expected to be more effective than current automotive original equipment manufacturer (OEM) embedded systems for lane departure, adaptive cruise control, blind spot detection, rear parking sonar and backup camera because V2V technology enables an ubiquitous 360-degree awareness of surrounding threats. V2V communication is part of the growing trend towards pervasive computing, a concept known as the Internet of Things (IoT).

In the United States, V2V is an important part of the intelligent transport system (ITS), a concept that is being sponsored by the United States Department of Transportation (DOT) and the National Highway Traffic Safety Administration (NHTSA). An intelligent transport system will use the data from vehicle-to-vehicle communication to improve traffic management by allowing vehicles to also communicate with roadside infrastructure such as traffic lights and signs. The technology could become mandatory in the not-too-distant future and help put driverless-cars on highways across America.

 

The implementation of V2V communication and an intelligent transport system currently has three major roadblocks: the need for automotive manufacturers to agree uponstandardsdata privacy concerns and funding. As of this writing it is unclear whether creation and maintenance of the supporting network would be publicly or privately funded. Automotive manufacturers working on ITS and V2V include GM, BMW, Audi, Daimler and Volvo.
