Robot Poet Composes The Sands Of Time
Jan 31, 2014 11:53 AM
| Now that robots are writing news stories and novels, the machines are getting their operating systems tweaked for more creative endeavors: poetry. Created by Dutch artist Gijs van Bon, “Skryf” is a robo-poet that composes its verse in a trail of sand. The tricycle like mechanism consists of a modified CNC milling machine on wheels, which van Bon controls via a laptop. Skryf is programmed to take its time and print the lines so that by the time the poem is finished, the first lines have been destroyed. Van Bon says this is intentional — a statement about the fleeting nature of poetry. “When you’re writing one line of text, another one is going away because people start walking through it,” he told Dezeen. “Once I’ve finished writing, I walk the same way back but it’s all destroyed. It’s ephemeral, it’s just for this moment and afterwards it’s left to the public and to the wind.” Unlike some artificially intelligent robots that generate content, Skryf’s words are chosen by Van Bon. ”I can just type in text and it converts it to a code that the machine accepts,” he explained. “It writes letter by letter and in the four hours that I write per day it will write about 160 meters.” (adapted from http://news.discovery.com/tech/robotics/ robot-poet-composes-the-sands-of-time-140131.htm) |

Ocean Acidification
Carbon Dioxide Is Putting Shelled Animals at Risk
For tens of millions of years, Earth’s oceans have maintained a relatively stable acidity level. It’s within this steady environment that the rich and varied web of life in today’s seas has arisen and flourished. But research shows that this ancient balance is being undone by a recent and rapid drop in surface pH that could have devastating global consequences.
Since the beginning of the industrial revolution in the early 1800s, fossil fuel-powered machines have driven an unprecedented burst of human industry and advancement. The unfortunate consequence, however, has been the emission of billions of tons of carbon dioxide (CO2) and other greenhouse gases into Earth’s atmosphere.
Scientists now know that about half of this anthropogenic, or man-made, CO2 has been absorbed over time by the oceans. This has benefited us by slowing the climate change these emissions would have instigated if they had remained in the air. But relatively new research is finding that the introduction of massive amounts of CO2 into the seas is altering water chemistry and affecting the life cycles of many marine organisms, particularly those at the lower end of the food chain.

TEXTO
PARA TUDO E PARA TODOS
José Casado, O Globo, 21/01/2014
| Quando ronca, o motor do caminhão ecoa trovoada. É só lembrança – esperança de sertanejo. São 8.558 “pipeiros” contratados pelo governo para levar água a 1.087 lugarejos, onde a caatinga estende-se “de um vermelho indeciso salpicado de manchas brancas que eram ossadas” – como descreveu o alagoano Graciliano Ramos 76 anos atrás. A vida continua na seca. Nos últimos três meses, os “pipeiros” desapareceram de algumas áreas do sertão cearense. A Assembleia Legislativa recebeu relatos de quatro dezenas de casos e identificou a origem do problema: os contratados não prestaram contas ao governo. Seguiu-se um “rigoroso inquérito administrativo”. Até acabar, não sai pagamento. Muito menos “pipa”. Faz tempo que as últimas arribações sumiram do céu azul. Na vida em tempo de seca braba, fartura só de sede. E de burocracia. Mais abaixo, em Natal (RN), o governo anuncia a devolução de verbas federais (R$ 10 milhões, com juros). O dinheiro não foi investido, como previsto, em segurança pública estadual “devido a fatores burocráticos”. Dois mil quilômetros ao sul, em Araçatuba (SP), a prefeitura conseguiu terminar a reforma de um Restaurante Popular, capaz de servir até 300 pratos de comida por dia. A obra custou R$ 1 milhão. Atravessou longos 28 meses, na cadência de falência de fornecedores, mudanças no projeto e licitações refeitas. Está pronto, mas continuará fechado. Até a liberação federal. (....) Há 47 anos, por decreto da ditadura, aboliu-se a exigência de reconhecimento de firma em documentos. Agora, 17 mil dias depois a Receita Federal anuncia em portaria que, em oito semanas, vai cumprir essa regra de boa-fé nas relações com os contribuintes. Com uma exceção, ressalva: “Nos casos em que a lei determine”. Regulamentos não faltam. Foram editados 4,7 milhões desde a Constituição de 1988, calcula o Instituto Brasileiro do Planejamento e Tributação. São 524 novos por dia. Na eleição presidencial de outubro o país deverá somar 5 milhões de leis e normas, para tudo e para todos. É um caso de suicídio nacional por asfixia burocrática. |
