Arte ruso retro-futurista

Arte procedente de la SF rusa.

Dark Roasted Blend: Retro-Future: To The Stars!

Space never looked better... and perhaps never will

Retro-futuristic art, in a way, is a double-fantasy: imaginary future wrapped in imaginary past. Which makes this style doubly interesting, if not doubly obsolete... In this part we will showcase rarely seen art, done in 1930s to 1970s, mostly from "Teknika Molodezhi" (TM), Yuny Tekhnik, DetGiz (Russia) and German retro-future sites.

Reflexiones de un gay neoconservador

Ampliando perspectivas :-) Esta reflexión resulta especialmente poética.
Enfoque Gay

Y es por eso que resulta tan difícil asumir la idea, empáticamente y desde un punto de vista intelectual, de que Dios pueda rechazar a una de Sus criaturas porque ésta ame. No consigo ver el rostro pérfido de esa conducta, la faceta malvada del amor. Y es también por eso por lo que uno puede ser homosexual y amar a Cristo sin sentirse culpable, frustrado ni rechazado. ¿Piensas que se trata de un examen un poco simple? Quizás, quizás, pero, ¿con qué instrumentos contamos para desenvolvernos en la difícil relación con Dios? ¿Y qué energía atávica nos anima? ¿No es el amor? ¿No es la emoción constructiva que conduce a la fusión de las almas? Y si dos almas se unen por medio de ella, ¿es asequible la idea de que esa unificación desinteresada conduzca al alejamiento de Dios, o sucedería más bien todo lo contrario?

Marketing viral: ya saben cómo vendernos la moto por internet

La estrategia resumida:

• hacer un vídeo pegadizo
• pasar la "curva de masa crítica", haciendo artificialmente que esté en la lista de los "más vistos de hoy" (pagando por enlazarlo en blogs famosos, creando cuentas fantasma que enlazan entre sí, posteándolo como comentario en conversaciones...)
• al principio poner un título engañoso que cause curiosidad, luego cambiarlo por "lo que la gente está buscando"
• explotar la tecnología de sitios populares, optimizando para para que la presentación llame la atención (imagen previa interesante, etiquetas que hacen aparecer en "videos relacionados" todos los de la misma empresa...) - resumiedo, nuevas técnicas de "optimización en buscadores".
  
• hacer comentarios controvertidos, pero borrar los comentarios realmente negativos
• hacer un seguimiento de la visualización, para medir el impacto real de cada técnica usada (para poder refinarlas).
  

La duda es, ¿por qué este tipo está desvelando públicamente sus técnicas profesionales de promoción publicitaria?


The Secret Strategies Behind Many “Viral” Videos

Have you ever watched a video with 100,000 views on YouTube and thought to yourself: “How the hell did that video get so many views?” Chances are pretty good that this didn’t happen naturally, but rather that some company worked hard to make it happen – some company like mine.

Over the past year, I have run clandestine marketing campaigns meant to
ensure that promotional videos become truly viral, as these examples
have become in the extreme. In this post, I will share some of the
techniques I use to do my job: to get at least 100,000 people to watch
my clients’ “viral” videos.

Consejos sobre tarjetas de crédito

Cómo no meterse en líos con los créditos

Slashdot | The Evolving Face of Credit Card Scams

• Get on the OPTOUT list to stop preapproved offers.
• Don't accept a card with a yearly fee, unless there are travel or purchase rewards that you're sure you will use.
• If you have good credit, ignore all offers above 10-12% (excepting rewards cards). I have a 7.9% national city card.
• Don't open new credit card accounts if you're about to buy a house or car.
• Reject offers at the register. There's no possible way you can read the fine print at the checkout.
• Only consider accepting an offer at the register if the discount is
  at least $50. 10% of $500+. Deactivate the card after a few weeks or so.
• Don't ignore a bill sent to you on a deactivated card. It won't go away on its own.
• Don't signup for insurance through your credit card company. Buy insurance directly from an insurance company.
• Don't transfer debt onto a new card unless its free. No percent fee and no minimum fixed fee.
• A free transfer to a low or zero interest card is not a bad thing,
  so long as the introductory rate is long enough to be worth it, such as
  9-12 months, and the non-introductory rate is fair.
• Don't use convenience checks tied to the credit card. After the
  temporary rate expires, they nearly always apply as a cash advance
  (which is much higher rate).
• When not traveling, don't use ATMs outside the bank's network.
• Use a debit card for cash advances and groceries. Use a credit card for travel, online purchases, shipping, and other purchases.
• Occasionally check your online statement history for unexplained
  purchases. I do this at least 3-4+ times a month, usually at work as an
  excuse to goof off for a moment.
• Setup a minimum fee payment schedule on all your credit cards
  within each respective card company even if you rarely carry balances.
  Don't use a 3rd party bill-pay for credit cards. If the bill-pay is
  down, you'll be held responsible if you're late. You have a stronger
  case for dropping late fees if it's your own credit card company's
  fault.

Algunas preguntas básicas sobre ciencia

Conceptos elementales del funcionamiento de la ciencia, explicados para el público en general.

Algunas preguntas básicas sobre ciencia | Teleobjetivo

Del mismo modo que no tiene sentido preguntar por las revoluciones por minuto de un trozo de acero (a pesar de que los motores están hechos de este metal), tampoco tiene ningún sentido pretender describir su funcionamiento a partir de las propiedades químicas del metal. Otro ejemplo sería que, a pesar de que el acero no flota, los barcos si flotan (a pesar de que están hechos de acero).

En resumen, cuando hablamos de ciencia el primer concepto a tener claro es que las leyes naturales tienen un ámbito de aplicación concreto, y que fuera de ese ámbito no solo no tienen sentido, sino que pueden llevarnos a contradicciones y paradojas.

Entrevista: Linux en el instituto

Entrevista al director de un instituto de Sigüenza, que gracias a Linux ha puesto un ordenador en cada aula.

El Afilador | Linux en el instituto

Preguntamos sobre las características de la instalación a la empresa de informática seguntina Entorno PC. Nos recalcan el aspecto ecológico de estas actuaciones, “los ordenadores que se han reutilizado, si no hubiéramos puesto Linux, su destino hubiera sido la basura”. Se ha instalado Molinux, una distribución de Linux creada por la de la Junta de Castilla-La Mancha, concretamente la versión denominada Rocinante. Sobre los requisitos mínimos para instalación dicen que “con 256 de memoria Ram o incluso con menos se puede llevar a cabo”. Hay que tener en cuenta que “ahora con la nueva versión de Windows, el Vista, con un 1Gb de Ram incluso tienes problemas comprándote un ordenador nuevo”.

Una sencilla teoría de todo

Según esa teoría, este es el universo (por dentro):


La teoría utiliza un objeto matemático que recién se ha calculado por completo, el grupo de simetrías E8. El autor ha hecho corresponder las partículas subatómicas conocidas -para las 4 fuerzas fundamentales- con las distintas partes de las simetrías. Le aparecen 20 nuevas partículas no conocidas, que podrían ser descubiertas experimentalmente y podrían confirmar la teoría. Éste es el mejor comentario en slashdot sobre la teoría.
Aquí se explica qué es el E8 (si sabes algo de espacios vectoriales), y cómo lo calcularon:


Slashdot | A New Theory of Everything?

"The Telegraph is running a story about a new Unified Theory of Physics. Garrett Lisi has presented a paper called "An Exceptionally Simple Theory of Everything" which unifies the Standard Model with gravity — without using string theory. The trick was to use E8 geometry which you may remember from an earlier Slashdot article. Lisi's theory predicts 20 new particles which he hopes might turn up in the Large Hadron Collider."

Tinta mágica: eliminando la interfaz de usuario

Este artículo presenta una teoría unificadora de la "interfaz invisible". Temas de psicología cognitiva, programación basada en ejemplos / por demostración...

Este tío sabe de lo que habla.


Magic Ink: Information Software and the Graphical Interface

Reducing interaction


# When the user is forced to interact, the software assumes the form of manipulation software. The external model, manipulated through navigation, is the software’s model of the context. However, unlike genuine manipulation software, the user does not care about this model—it is merely a means to the end of seeing relevant information.

# The designer’s goal is to let the user adequately shape the context model with as little manipulation as possible. Assuming that graphic design, history, and the environment have been taken as far as they will go, there are a few techniques that can lessen the impact of the remaining interaction:

* Graphical manipulation domains present the context model in an appropriate, informative setting.
* Relative navigation lets the user correct the model, not construct it.
* Tight feedback loops let the user stop manipulating when she’s close enough.

Concurrencia funcional en el lenguaje E

Un ejemplo de paralelismo manejado por un lenguaje de alto nivel.

Walnut/Distributed Computing - Erights

Eventually Operator

All distributed computing in E starts with the eventually operator, "<-":

 # E syntax
 pragma.syntax("0.9")
 car <- moveTo(2,3)
 println("car will eventually move to 2,3. But not yet.")

Promises

When you make an eventual send to an object (referred to hereafter simply as a send, which contrasts with a call
to a local object that waits for the action to complete), even though
the action may not occur for a long time, you immediately get back a
promise for the result of the action:

 # E syntax
 def carVow := makeCar <- ("Mercedes")
 carVow <- moveTo(2,3)

Interactive Scientific Visualization Techniques

A “human-centered” environment uses both interactions and visualizations that take into account more fully a human’s performance and capabilities than currently supported in today’s desktop interfaces. These environments can support wide-field-of-view, stereoscopic display, and multimodal interaction including gesture-based interactions to create systems that take the best from both computer and noncomputer based interactions.

Medir el User Experience - HOWTO

Encuesta para medir numéricamente la calidad de la experiencia de usuario, en cuatro áreas:

How To Quantify The User Experience [Usability and Information Architecture]

Branding

Branding includes all the aesthetic and design-related items within
a Website. It entails the site's creative projection of the desired
organizational image and message. Statements used to measure branding
can include:

• The site provides visitors with an engaging and memorable experience.
• The visual impact of the site is consistent with the brand identity.
• Graphics, collaterals and multimedia add value to the experience.
• The site delivers on the perceived promise of the brand.
• The site leverages the capabilities of the medium to enhance or extend the brand.

  
  Functionality

• 
  
  

  Functionality includes all the technical and 'behind the scenes'
  processes and applications. It entails the site's delivery of
  interactive services to all end users, and it's important to note that
  this sometimes means both the public as well as administrators.
  Statements used to measure a site's functionality can include:

  
  
  
• Users receive timely responses to their queries or submissions.
• Task progress is clearly communicated (e.g., success pages or email updates).
• The Website and applications adhere to common security and privacy standards.
• Online functions are integrated with offline business processes.
• The site contains administration tools that enhance administrator efficiency.

Usability

Usability entails the general ease of use of all site components and
features. Sub-topics beneath the usability banner can include
navigation and accessibility. Statements used to measure usability might include:

• The site prevents errors and helps the user recover from them.
• Overall page weight is optimized for the main target audience.
• The site helps its visitors accomplish common goals and tasks.
• The site adheres to its own consistency and standards.
• The site provides content for users with disabilities.

Content

Content refers to the actual content of the site (text, multimedia,
images) as well as its structure, or information architecture. We look
to see how the information and content are structured in terms of
defined user needs and client business requirements. Statements used to
measure content can include:

• Link density provides clarity and easy navigation.
• Content is structured in a way that facilitates the achievement of user goals.
• Content is up-to-date and accurate.
• Content is appropriate to customer needs and business goals.
• Content across multiple languages is comprehensive.
