Stanford computer scientists create crowdsourcing website to draw ... crowds

Stanford computer scientists create crowdsourcing website to draw ... crowds | Historia de la Informática | Scoop.it

"Stanford computer scientists have created a website to help organizers plan events that are more likely to succeed or allow them to pull the plug on impending flops before they occur.

The website, called Catalyst, is based on a behavioral science concept known as the threshold model of collective action, which posits that people may be reluctant to commit to participating in activity until they see others taking part, at which point interest surges and the activity becomes successful. But if participation doesn’t reach this threshold point, the event is likely to fail.

Catalyst builds this principle into software. The website allows people to enter a few details, such as date, time, description of the event and the number of participants needed to make it a success. If signups don't hit this threshold point by the deadline, Catalyst emails organizers and would-be participants a warning."

Good concept but like meetup- what about those serial signer-uppers that don't show? You have to make an event seem VIP to get certain demographic to attend.

El error más tonto en la historia de la NASA - Blogs de No me creas

El error más tonto en la historia de la NASA - Blogs de No me creas | Historia de la Informática | Scoop.it
El error más tonto en la historia de la NASA El 23 de septiembre de 1999, la Mars Climate Orbiter desapareció de los monitores de la NASA.

 

En la semanas siguientes se organizó una comisión de investigación para aclarar qué había sucedido. Y, tras numerosos informes, peritajes y entrevistas, la conclusión no pudo ser más humillante para la agencia espacial estadounidense: habían cometido un error en las unidades de medida.

 

El control de Tierra usaba el sistema métrico decimal, mientras que la nave realizaba los cálculos en el sistema anglosajón. Así, cada vez que los controladores ordenaban a la nave que variase su trayectoria, enviaban unos datos en newtons que la nave interpretaba como si fuesen libras. Una libra equivale a 4,45 newtons, por lo que cada corrección de trayectoria provocaba una desviación aún mayor.

 

De ahí que, cuando los técnicos decidieron frenar la nave para su aproximación a Marte, ésta estaba ya calcinándose en la atmósfera marciana, a poco más de 50 kilómetros sobre la superficie.

Paul Allen and the Machines: Teaching the next generation of artificial intelligence

Paul Allen and the Machines: Teaching the next generation of artificial intelligence | Historia de la Informática | Scoop.it

Microsoft co-founder Paul Allen has been pondering artificial intelligence since he was a kid. In the late '60s, eerily intelligent computers were everywhere, whether it was 2001's HAL or Star Trek's omnipresent Enterprise computer. As Allen recalls in his memoir, "machines that behaved like people, even people gone mad, were all the rage back then." He would tag along to his father's job at the library, overwhelmed by the information, and daydream about "the sci-fi theme of a dying or threatened civilization that saves itself by finding a trove of knowledge." What if you could collect all the world's information in a single computer mind, one capable of intelligent thought, and be able to communicate in simple human language? 

Forty years later, with nearly 9 billion dollars to Allen's name, that idea is beginning to seem like more than just fantasy. Much of the technology is already here. We talk to our phones and aren't surprised when they talk back. A web search can answer nearly any question, undergirded by a semantic understanding of the structure of online information. But while the tools are powerful, the processes behind them are still fairly basic. Siri only understands a small subset of questions, and she can't reason, or do anything you might call thinking. Even Watson, IBM'sJeopardy champ, can only handle simple questions with unambiguous phrasing. Already, Google is looking to the Star Trek computer as a guiding light for its voice search — but it's still a long way off. If technology is going to get there, we'll need computers that are better at talking and, more crucially, better at reasoning.

9-Dic-1968: Douglas Engelbart realiza "La Madre de Todas las Demos" | Historia de la Informática | Scoop.it

9-12-1968 Se lleva a cabo la "madre de todas las demos" en San Francisco's Brooks Hall.

 

Douglas Engelbart da comienzo a la revolución de las computadoras personales con la demostración de un producto que inspiraría toda una generación de tecnólogos. La presentación incluyó el debut del mouse, el concepto "what you see is what you get" , texto y gráficos en una misma pantalla, videoconferencia, ventanas, ayuda contextual e hipervínculos.

 

Engelbart recibió la Medalla Nacional de Tecnología en el año 2000 por "la creación de los fundamentos de la computación personal".

 

Valga este post como homenage al padre de la computación personal.

Synaptic Transistor Learns While it Computes,brain-inspired device looks toward highly efficient and fast parallel computing.

Synaptic Transistor Learns While it Computes,brain-inspired device looks toward highly efficient and fast parallel computing. | Historia de la Informática | Scoop.it
A new brain inspired device, which learns while it computes, could take parallel computing into a new era of ultra efficient high performance.

It doesn’t take a Watson to realize that even the world’s best supercomputers are staggeringly inefficient and energy-intensive machines.

Our brains have upwards of 86 billion neurons, connected by synapses that not only complete myriad logic circuits; they continuously adapt to stimuli, strengthening some connections while weakening others. We call that process learning, and it enables the kind of rapid, highly efficient computational processes that put Siri and Blue Gene to shame.

Materials scientists at the Harvard School of Engineering and Applied Sciences (SEAS) have now created a new type of transistor that mimics the behavior of a synapse. The novel device simultaneously modulates the flow of information in a circuit and physically adapts to changing signals.

Exploiting unusual properties in modern materials, the synaptic transistor could mark the beginning of a new kind of artificial intelligence: one embedded not in smart algorithms but in the very architecture of a computer. The findings appear in Nature Communications.
