Analisis de Java
|
Muchos de los articulos que estado leendo en estos ultimos dias mencionan el mal uso del lenguaje de programacion denominado Java, un potente lenguaje que no se esta utilizando de la mejor manera la mayoria de los estudiantes utilizan Java solo para armar programas sencillos como muchos y no se dedican a generar librerias nuevas o generar nuevo codigo, es por esto que recolecte un fragmento del comentario de dos Catedráticos en Cs. de la Computación en EEUU. que dice:
Diario Ti: Los catedráticos eméritos Robert B.K. Dewar y el Dr. Edmond Schonberg, de la Universidad de Nueva York, EE.UU., pertenecen a la elite informática en ese país.
Ambos critican lo que califican de "uso indiscriminado de Java en la formación de estudiantes de informática". A juicio de los catedráticos, "Java es un atajo, una solución fácil", en lugar de lo que denominan "verdadera programación".
"El resultado es un estudiante que sabe como armar un programa sencillo, pero que no sabe como programar", escriben Dewar y Schonberg en el sitio STSC Crosstalk.
Ambos proponen un retorno de los antiguos y sólidos lenguajes de programación como C, C++, Lisp y ADA, que califican de "conocimientos elementales" para todo estudiante de informática.
"Java tiene una misión, pero no puede ser usado como la primera o única opción", concluyen los catedráticos.

..::Una pelicula para la Historia de la Computación::..
|
Amigos les presente una de las peliculas que realmente puede entender a nuestra generación, conocer una imagen que podemos investigar de los dos Grandes de la Computación Actual, claro fuera de Google que creo que tendra una historia similar, pero no con tanto drama.
Muestro esto a mis alumnos para que se den cuenta que la evolucion no consiste en reinventar la rueda, y que solo la tenemos que utilizar, ver necesidades y crear soluciones con un ordenador o computador PC, recomiendo que lo descarguen que tomara unos cuantos minutos, pero les doy un 10 de calificación en orden 1 a 10, recomiendo que la vean si no son de la generación de la era de la información van a tener que preguntar a los niños o jovenes escolares para actulizar sus conocimientos de computación.
Pero hable tanto y de que hablo, hablo de una pelicula PIRATAS DE SILICOM VALLEY, alli veremos actuar al propio BILL GATES, y al grande de Apple Steve Jobs.
Mi recomendación es que la vean con mucha paciencia, y analicen los comentarios de los actores.
Saludos de @ldoz puno

..::A Googly MySQL Cluster Talk::..

Otra interesante ponencia de google. Espero sus opiniones
Google TechTalks April 28, 2006
Stewart Smith Stewart Smith works for MySQL AB as a software engineer working on MySQL Cluster. He is ... todos » an active member of the free and open source software community, especially in Australia.
ABSTRACT Part 1 - Introduction to MySQL Cluster The NDB storage engine (MySQL Cluster) is a high-availability storage engine for MySQL. It provides synchronous replication between storage nodes and many mysql servers having a consistent view of the database. In 4.1 and 5.0 it's a main memory database, but in 5.1 non-indexed attributes can be stored on disk. NDB also provides a lot of determinism in system resource usage. I'll talk a bit about that.
Part 2 - New features in 5.1 including cluster to cluster replication, disk based data and a bunch of other things. anybody that is attending the mysql users conference may find this eerily familiar.

Computers versus Common Sense
|
Todo esto es publicado para el analisis de mis alumnos.. Douglas Lenart plantea una teoria de como la coputacion afecta a el ser humano de una manera muy cientifica... escuchen su exposicion
Douglas Lenat Dr. Douglas Lenat is the President and CEO of Cycorp. Since 1984, he and his team have ... todos » been constructing, experimenting with, and applying a broad real world knowledge base and reasoning engine, collectively "Cyc".
Dr. Lenat was a professor of computer science at Carnegie-Mellon University and at Stanford University. His interest and experience in national security has led him to regularly consult for several U.S. agencies and the White House.
ABSTRACT It's way past 2001 now, where the heck is HAL? For several decades now we've had high hopes for computers amplifying our mental abilities not just giving us access to relevant stored information, but answering our complex, contextual questions.
Even applications like human-level unrestricted speech understanding continue to dangle close but just out of reach. What's been holding AI up? The short answer is that while computers make fine idiot savants, they lack common sense: the millions of pieces of general knowledge we all share, and fall back on as needed, to cope with the rough edges of the real world. I will talk about how that situation is changing, finally, and what the timetable -- and the path -- realistically are on achieving Artificial Intelligence

There are People in our Computers!

Exposicion de: There are People in our Computers! , tema amplio para discutir, y tener en cuenta como detalle de investigacion para futuras tesis
David Wolber (http://cs.usfca.edu/~wolber) is a professor at the University of San Francisco. His ... todos » interests include collaborative research systems, e-politics, and service learning within computer science.
ABSTRACT Peoplicious is a collaborative research tool. Unlike systems such as del.icio.us, people are first-class data objects, along with documents. Users can create people, provide structured information about people (image, homepage, blog feed, delicious name, etc.), and create lists of people (people-tagging). Users can also bookmark documents and associate documents with people (personmarks). Any user can enter information about any person.
Peoplicious is where del.icio.us meets RSS reader all within a modern day address book. There is a working prototype that can be accessed at: http://peoplicious.com/Technorati/lists. It is designed so that new sites can easily be created for particular domains (e.g., see http://peoplicious.com/USF/lists). The system currently has one power user.

..::How To Break Web Software - A look at security vulnerabilities in web software::..

Este si es un video que me volvio loko, muy buena teoria, me incentiva a investigar mas del area. suerte veanlo y que opiniones tienen...
Mike Andrews
Mike Andrews is a senior consultant who specializes in software security and leads the ... todos » web application security assessments and Ultimate Web Hacking classes for Foundstone.
ABSTRACT It all started out as a place to share physics documents, but has grown into potentially mankind's largest and most complex creation. The World Wide Web is a lot of things - a soapbox for everyone, a giant shopping mall, an application platform, and unfortunately a hacker's playground.
As more applications get "web-ified" moving from the desktop or legacy systems onto the web, attackers follow the vulnerabilities. Without sophisticated tools or "1337 5x1llz", web applications are now the most attacked technology, with the majority of attacks categorized as "easily exploitable".
So, before your application is placed out into one of the most hostile environments, how do you stop your software from being "0wn3d" by the 14 year old in their blacked-out bedroom, or being used by a Russian crime cartel?
In this TechTalk, Mike Andrews will look at how web applications are attacked, walk through a testing framework for evaluating the security of an application and take some deep-dives into a few interesting and common vulnerabilities and how they can be exploited.

Es un interesante y fructifero video que nos muestra un trabajo de investigacion, en donde lo mas interesante es la interacion humana computador. y plantea algunas soluciones. Lo publico para el analisis de mis alumnos... un abrazo.
Carnegie Mellon University, ... todos » where he also received his Ph.D. in 2005. Previously, Luis obtained a B.S. in mathematics from Duke University in 2000. He is the recipient of a Microsoft Research Fellowship.
ABSTRACT Tasks like image recognition are trivial for humans, but continue to challenge even the most sophisticated computer programs. This talk introduces a paradigm for utilizing human processing power to solve problems that computers cannot yet solve. Traditional approaches to solving such problems focus on improving software. I advocate a novel approach: constructively channel human brainpower using computer games. For example, the ESP Game, described in this talk, is an enjoyable online game -- many people play over 40 hours a week -- and when people play, they help label images on the Web with descriptive keywords. These keywords can be used to significantly improve the accuracy of image search. People play the game not because they want to help, but because they enjoy it.
I describe other examples of "games with a purpose": Peekaboom, which helps determine the location of objects in images, and Verbosity, which collects common-sense knowledge. I also explain a general approach for constructing games with a purpose

Multi Touch
|
Uno de los mejores videos que pude encontrar sobre la experimentacion de Multi Touch, la tecnologia adecuada para el presente del mercado de computadores en el Mundo. Si tienen unos mejores avisenme esta tecnologia poco a poco esta ingresando a mi Pais, pero creo que no soporta mucho las alturas de Puno, espero que los investigadores desarrollen mayor resistencia a el frio y altura.
Y recuerden:
"Una persona es una persona a causa de las demás, la identidad se basa en el hecho de ser visto, de que la gente te respete y reconozca como persona"
