Seaside
The new guy in town is Seaside. Seaside arrived several years ago with little fanfare because it runs on Squeak, a relatively new version of Smalltalk. As you may know, Smalltalk is an “old” language that most of us have only heard the old-timers get sentimental about when they talk about the Good Old Days of the Computer Science Frontier. It turns out that the Old is New again....

Smalltalk vs java
Comparing Smalltalk and Java
In “On OOA and Simplicity (Part 1)”, Samuel Falvo says:
In short, it’ll take you, the programmer, substantially longer to implement a properly OO solution to any problem in Java than it would in Smalltalk. What this means is that a company will shell out more cash for proper OO solutions in Java than they would in Smalltalk. Period. The economics...

Squeak asusta?
Squeak Smalltalk is wholly unlike any other open source programming tool you’ve worked with – and mostly in good ways. Unfortunately, it’s the bad ways that make the first impression. This hands-on tutorial will help you get past the unfamiliar and the unwieldy so that you can take advantage of the elegant and productive environment that lies underneath. We’ll cover what makes Smalltalk so...

Pomodori 0.3
reborg:
I’m happy to announce Pomodori release 0.3. Just follow the link and the installation instructions on the page. For those who don’t know, Pomodori is the pomodoro management application I’m using every day since February. “819 pomodoros and counting!” is what I see right now. Pomodori isn’t just a timer, it’s a tool implementing the Pomodoro Technique. At this point Pomodori is missing...

SmallTalk in SmallPlaces
reborg:
I had less time to read/listen/watch in the last two weeks. So I skipped the summary of the most interesting reading for the last week. Ok, let’s talk about SmallTalk then. I’m very disappointed I never found the time to learn about what can be considered the father of all the modern languages you hear about. Unfortunately I need to keep this desire low priority in my task list for some...

Smalltalk en frances
Smalltalk est un langage, un environnement de développement, qui mérite à être connu. Avec un modèle objet simple, clair et cohérent, des mécanismes réflexifs sophistiqués (c’est-à-dire la possibilité pour le programme de modifier sa structure et son comportement lors de l’exécution) et des outils de développement évolués, il permet de se concentrer sur l’essentiel : écrire...

GUI, programacion visual y Squeak
Squeak includes a number of user interface frameworks:
1 An implementation of Morphic, Self’s graphical direct manipulation interface framework. This is Squeak’s main interface.
2 Tile-based, limited visual programming scripting in Etoys, based on Morphic.
3 A new, experimental interface called Tweak. In 2001, it became clear that the Etoy architecture in Squeak had reached its...

Redes neuronales
Las redes de neuronas artificiales (RNA o ANN en inglés) son un paradigma de aprendizaje y procesamiento automático inspirado en la forma en que funciona el sistema nervioso de los animales. Se trata de un sistema de interconexión de neuronas en una red que colabora para producir un estímulo de salida.
Las redes neuronales consisten en una simulación de las propiedades observadas en los sistemas...

Realidad virtual inmersiva
Los métodos inmersivos de realidad virtual se ligan a un ambiente tridimensional creado por un ordenador, el cual se manipula a través de cascos, guantes u otros dispositivos que capturan la posición y rotación de diferentes partes del cuerpo humano. La realidad virtual no inmersiva también utiliza el ordenador y se vale de medios como el que actualmente nos ofrece Internet, en el cual podemos...

Realidad virtual
Realidad virtual es un sistema o interfaz informático que genera entornos sintéticos en tiempo real, representación de las cosas a través de medios electrónicos o representaciones de la realidad, una realidad ilusoria, pues se trata de una realidad perceptiva sin soporte objetivo, sin red extensa, ya que existe sólo dentro del ordenador. Por eso puede afirmarse que la realidad virtual es una...

Inteligencia artificial
Se denomina inteligencia artificial a la rama de la ciencia informática dedicada al desarrollo de agentes racionales no vivos.
Para explicar la definición anterior, entiéndase a un agente como cualquier cosa capaz de percibir su entorno (recibir entradas), procesar tales percepciones y actuar en su entorno (proporcionar salidas). Y entiéndase a la racionalidad como la característica que posee una...

Realidad aumentada
Augmented reality (AR) is a term for a live direct or indirect view of a physical real-world environment whose elements are merged with-, or augmented by virtual computer-generated imagery - creating a mixed reality. The augmentation is conventionally in real-time and in semantic context with environmental elements. With the help of advanced AR technology (e.g. adding computer vision and object...

Demoscene
La demoscene es una subcultura informática. Las demos comenzaron siendo una firma de los crackers de software, quienes se daban crédito modificando los programas para que, cuando se iniciaran, se viera una presentación gráfica impresionante, también llamada “intro”. Más adelante, estas intros evolucionaron hacia una cultura independiente de los grupos de cracking. Muchos de los jóvenes...

lenguajes dinamicos
Dynamic programming language is a term used broadly in computer science to describe a class of high-level programming languages that execute at runtime many common behaviors that other languages might perform during compilation, if at all. These behaviors could include extension of the program, by adding new code, by extending objects and definitions, or by modifying the type system, all during...

Generacion procedural
Procedural generation is a widely used term in the production of media, indicating the possibility to create content on the fly rather than prior to distribution. This is often related to computer graphics applications and video game level design.
The term procedural refers to the process that computes a particular function. Fractals, an example of procedural generation, dramatically expresses...

Modelado procedural
Procedural modeling is an umbrella term for a number of techniques in computer graphics to create 3D models and textures from sets of rules. L-Systems, fractals, and generative modeling are procedural modeling techniques since they apply algorithms for producing scenes. The set of rules may either be embedded into the algorithm, configurable by parameters, or the set of rules is separate from the...

Sistemas generativos
Generative Systems refers to systems that use a few basic rules to yield extremely varied and unpredictable patterns.
Video game designer Will Wright and musician Brian Eno.
Generativity of a system is premised on five principle factors:
1 How extensively a system of technology leverages a set of possible tasks;
2 How well it can be adapted to a range of tasks;
3 How easily new contributors...

Arte evolucionario
Evolutionary Art exploits the process of evolution to create an artwork which continually changes according to an evolutionary algorithm.
In common with natural selection and animal husbandry, the members of a population undergoing artificial evolution modify their form or behaviour over many reproductive generations in response to a selective regime.
In interactive evolution the selective...

Arte generativo
Generative art is a system oriented art practice where the common denominator is the use of systems as a production method. To meet the definition of generative art, an artwork must be self-contained and operate with some degree of autonomy. The workings of systems in generative art might resemble, or rely on, various scientific theories such as Complexity science and Information theory. The...

Textura procedural
Textures are stored as texture descriptors. These descriptors describe how to reproduce the texture, not the image itself. They may, for example, describe a series of mathematical functions that applied in a specific order, reproduce the image.

Geometria procedural
Geometry is specified by a geometry descriptor which can be very small. A piece of code expands the geometry descriptor into points, polygons, normals and texture co-ordinates.
A comon technique used to combine simple geometric shapes is sometimes called multiplicative geometry. The idea is to repeatedly draw the same base shape over and over, constructing a large complex scene of geometry from...

Graficos procedurales
What are Procedural Graphics?
The basic idea is to create, on-the-fly all graphics. Data structures are created and then filled with data generated from the code itself, rather than being loaded from files as above.
Nearly all procedural graphics start with some very small base data. This base data should be as small as possible. The base data forms the seed for the code which then expands it...
