Repressão não é a melhor saída para "rolezinhos", afirma Gilberto Carvalho
Lucioc> "Não considero a repressão o melhor caminho, porque tudo o que for feito nessa linha vai ser como colocar gasolina no fogo", disse.
E esse parece ser o grande mêda do governo federal, dessa fad de "rolezim" transformar 2014 em Junho de 2013, Extended Edition.
Ou pior. Obrigar milhares de pessoas dentro de um shóps a ouvir funk no último volume é o tipo de coisa que pode levar a golpes de estado e campos de concentração. Eu pegaria em archotes e ancinhos na hora, e foda-se se me chamassem de "racista" por isso. =)
Dilma anuncia investimento de R$ 1 bi no Semiárido
LuciocTalvez seja menos hipotético, teórico, intangível e etéreo que o dinheiro do metrô de BH, porque se o PT perder o Nordeste perde a eleição, basicamente.

whats the weirdest dream you ever had?
Lucioc"I had a dream I was a butcher in a deli on a old western themed reptilian alien planet. I was still human. Some gaucho velociraptors came in and said the meat they wanted was mine and I had a laser gun shoot out with them."
Porque não transformam idéias assim em filme? =)
im talkng about spooky surreal stuff, not random bullshit. links to your day to day, premonitions, psycho killer stuff. I'm fascinated by dreams and always try to make sense of mine (always sway from concluding that I'm a freak but sometimes its too hard not to)

TIL that the surface gravities of Venus, Saturn, Uranus, and Neptune are all quite similar (within 15%) to Earth's. Thus, the majority of planets in our solar system actually have Earth-like surface gravity.

Shoppings e Polícia Militar estão em alerta para os rolezinhos marcados para este fim de semana
LuciocEstou curioso para saber se os tais "rolezinhos" aqui de BH vão ter o fenômeno de "social divide" dos de SP.
Mas, se for o caso, o Minas Shóps pelo menos sempre foi um "rolezinho". ;)

Integrantes de "rolezinho" espancam policial em Guarulhos
LuciocNão sei o contexto do vídeo, mas talvez seja um contraponto para a narrativa que estou vendo emergir de que o tal rolezinho é um evento pacífico e inofensivo e que a repressão acontece "because I'm black".

Electric Sails: Fast Probe to Uranus
LuciocHilarity ensues, como em quase todo título de qualquer coisa sobre Urano.
For years now Pekka Janhunen has been working on his concept of an electric sail with the same intensity that Claudio Maccone has brought to the gravitational focus mission called FOCAL. Both men are engaging advocates of their ideas, and having just had a good conversation with Dr. Maccone (by phone, unfortunately, as I’ve been down with the flu), I was pleased to see Dr. Janhunen’s electric sail pop up again in online discussions. It turns out that the physicist has been envisioning a sail mission to an unusual target.
Let’s talk a bit about the mission an electric sail enables. This is a solar wind-rider, taking advantage not of the momentum imparted by photons from the Sun but the stream of charged particles pushing from the Sun out to the heliopause (thereby blowing out the bubble’ in the interstellar medium we call the heliosphere). As Janhunen (Finnish Meteorological Institute) has designed it, the electric sail taps the Coulomb interaction in which particles are attracted or repulsed by an electric charge. The rotational motion of the spacecraft would allow the deployment of perhaps 100 tethers, thin wires that would be subsequently charged by an electron gun with the beam sent out along the spin axis.

The electron gun keeps the spacecraft and tethers charged, with the electric field of the tethers extending tens of meters into the surrounding solar wind plasma — as the solar wind ‘blows,’ it pushes up against thin tethers that act, because of their charge, as wide surfaces against which the wind can push. The sail uses the attraction or repulsion of particles caused by the electric charge to ride the wind, the positively charged solar wind protons repelled by the positive voltage they meet in the charged tethers.
One disadvantage that electric sails bring to the mix, as opposed to solar sails like IKAROS, is that the solar wind is much weaker — Janhunen’s figures have it 5000 times weaker — than solar photon pressure at Earth’s distance from the Sun. This has come up before in comments here and it’s worth quoting Janhunen on the matter, from a site he maintains on electric sails:
The solar wind dynamic pressure varies but is on average about 2 nPa at Earth distance from the Sun… Due to the very large effective area and very low weight per unit length of a thin metal wire, the electric sail is still efficient, however. A 20-km long electric sail wire weighs only a few hundred grams and fits in a small reel, but when opened in space and connected to the spacecraft’s electron gun, it can produce several square kilometre effective solar wind sail area which is capable of extracting about 10 millinewton force from the solar wind.
Computer simulations using tethers up to 20 kilometers in length have yielded speeds of 100 kilometers per second, a nice step up from the 17 kps of Voyager 1, and enough to get a payload into the nearby interstellar medium in fifteen years. Or, as Janhunen describes in the recent paper on a Uranus atmospheric probe, an electric sail could reach the 7th planet in six years. Janhunen sees such a probe as equally applicable for a Titan mission and, indeed, missions to Neptune and Saturn itself, but notice that none of these are conceived as orbiter missions. A significant amount of chemical propellant is needed for orbital insertion unless we were to try aerocapture, but the problem with the latter is that it is at a much lower technical readiness level.
A demonstrator electric sail mission, then, is designed to keep costs down and reach its destination as fast as possible, with the interesting spin that, because we’re in need of no gravitational assists, the Uranus probe will have no launch window constraints. As defined in the paper on this work, the probe would consist of three modules stacked together: The electric sail module, a carrier module and an entry module. The entry module would be composed of the atmospheric probe and a heat-shield.
At approximately Saturn’s distance from the Sun, the electric sail module would be jettisoned and the carrier module used to adjust the trajectory as needed with small chemical thrusters (50 kg of propellant budgeted for here). And then the fun begins:
About 13 million km (8 days) before Uranus, the carrier module detaches itself from the entry module and makes a ~ 0.15 km/s transverse burn so that it passes by the planet at ~ 105 km distance, safely outside the ring system. Also a slowing down burn of the carrier module may be needed to optimise the link geometry during flyby.
Now events happen quickly. The entry module, protected by its heat shield, enters the atmosphere. A parachute is deployed and the heat shield drops away, with the probe now drifting down through the atmosphere of Uranus (think Huygens descending through Titan’s clouds), making measurements and transmitting data to the high gain antenna on the carrier module.
Thus we get atmospheric measurements of Uranus similar to what the Galileo probe was able to deliver at Jupiter, measuring the chemical and isotopic composition of the atmosphere. A successful mission builds the case for a series of such probes to Neptune, Saturn and Titan. Thus far Jupiter is the only giant planet whose atmosphere has been probed directly, and a second Jupiter probe using a similar instrument package would allow further useful comparisons. Our planet formation models, which predict chemical and isotope composition of the giant planet atmospheres, can thus be supplemented by in situ data.
Not to mention that we would learn much about flying and navigating an electric sail during the testing and implementation of the Uranus mission. The paper is Janhunen et al., “Fast E-sail Uranus entry probe mission,” submitted to the Meudon Uranus workshop (Sept 16-18, 2013) special issue of Planetary and Space Science (preprint).
China is cloning pigs on 'an industrial scale'
Lucioc'The Beijing Genomics Institute produces 500 cloned pigs a year, according to a BBC News report, making it the world’s biggest centre for cloning the animals.
It is also the world’s largest centre for gene sequencing of species of animals, particularly those that are "cute" or "taste good". '
São bons critérios, os chineses me parecem muito práticos. 8-)
Dreaming about seeing an asteroid for the second time, my sister, an armless man, aslan from narnia, carrots, thorns, a red-haired man with no back of head or brain and shinigami's from bleach?...
LuciocAh, finalmente um sonho interessante. Na última semana o r/dreams estava uma pasmaceira, só com sonhos de gente que foi no supermercado e pegou a namorada(o) com outro(a) e outras bobagens cotidianas que poderiam perfeitamente acontecer com a pessoa acordada.
Okay, as hilarious as the title sounds, it was kinda creepy.
I forgot which order its in and Im probably missing some stuff, but this is the best I remember it.
So I'm watching this woman on a TV show pick carrots, talking about either thorns or thistles, there's another woman with her but I forgot what she was there for... She take's the carrots away, leaving there to be a patch of wet mud with nothing but a few lame carrots... and worms and slugs.
Then some guy drives up to me and asks if I can give him the worms and slugs. I refuse to touch them, he laughs and then vanishes. Next thing I know he's back in his car with two missing arms and asks if I can do it once again. Followed by a mother fucking lion I know is Aslan from Narnia. The rest is kinda hazy.
Then I'm in the middle of a large crowd of people on a field. For some reason they're all gathered, but I dont know why. It starts to rain heavily and all of the children start screaming and crying, but they all stay. I on the other hand know better and try to warn them about something's going to happen. I try to run out of the field, some guy tries to stop me, but I make it out to the street. I see my sister coming out of a hospital and say something bads going to happen. Then, in the field, an asteroid strikes. Huge. Im not sure of the fate of the people inside. I say 'Oh god, I've seen this before...' my sister is in shock I was right and we both go to investigate whats at the gates. We jump back, since lava is spitting at us (from tiny puddles bursts forth insane amount of sparks... like falling molten metal) and we keep looking.
Next thing I know, I'm a guy with red hair in a hospital, lost. I'm far, far away from the place where it happened, but it still happened since it's on the news. I'm a different person. I was a sixteen year old boy getting used to calling himself '31' and the woman at the reception desk asked where I'm from. I told her about the place with the crashed asteroid and then she notices the back of my head, which is completely empty. No brain. No skin. No blood. I look out of the window, see something fall and then see some sort of waves coming at me. Three times, and I thought it was radiation. Then some shinigami from bleach got me out of the hospital, saying the guy was 'never going to leave me alone' and I was never going to be safe.

Low-Cost Flow Batteries. Powering city-sized electric grids reliably from intermittent sources requires storing electrical energy on an enormous scale. “This research could lead to new low-cost and efficient large-scale energy-storage systems.”
LuciocIdéia interessante, nessas "flow batteries" os fluidos armazenando a energia são desacoplados das células eletroquímicas - ficam em tanques externos e são bombeados através dessas quando energia precisa ser drenada ou armazenada.
Mas desconfio que o que seria bom *mesmo* seria sintetizar hidrocarbonetos - algum análogo sintético de gasolina e diesel - a partir de energia intermitente. Não precisaria alterar *nada* na infra-estrutura de transportes e energia da maior parte do mundo, tudo ficaria autocontido na usina éolica-solar...
TIL that the molecular structure of chlorophyll (the green coloring in plants) and hemoglobin ( the oxygen carrying structure in blood) are so similar that the difference is as little as a single atom of magnesium in chlorophyll being replaced by one of iron in hemoglobin.

The Fate of a City - CFN
Lucioc"There is theory which states that an empire puts up its greatest monumental buildings just before it collapses."
O artigo é sobre Niuiorque, que o Kunstler (sempre uma pessoa otimista e de altíssimo astral, tipo uma poster child do r/collapse =) prevê que vai entrar em uma horrenda era de declínio e virar de novo um lixão igual era nos 60s e 70s.
É meio difícil porém de usar essa teoria dos edifícios monumentais para prever alguma coisa, porque só sabemos que os edifícios monumentais foram os maiores *depois* que a sociedade colapsa. (A razão para as maiores construções precederem o colapso é simples: elas são economica e logisticamente viáveis quando a civilização está no apogeu, e depois do auge por definição vem o declínio.)
Batman/Superman e Liga da Justiça podem ser filmados ao mesmo tempo

Yutu Moon rover and Chang'e-3 lander wake up after sleeping through 14 Earth-day long lunar night.
Lucioc"The awakening of the rover and lander marks the success of Chinese technology in surviving the lunar night, and the center will instruct the two instruments to carry on scheduled exploration missions, the chief engineer added."
A propósito, os russos e americanos mandaram sondas nos 60s também - http://en.wikipedia.org/wiki/List_of_lunar_probes - mas desconfio que elas só aterrissavam, mandavam umas fotos e análises e depois morriam, sem entrar nesse "sleep mode". (Mas estou com preguiça de conferir.)
Ah, ok, tinha este robozinho russo aqui: http://en.wikipedia.org/wiki/Lunokhod_2 . Ele usava uma bateria de plutônio para ficar quentinho na noite lunar; já o jipinho e o lander dos chineses parece conseguir isso com baterias convencionais mesmo. (Well, teve um avanço razoável de tecnologia de baterias de lá para cá, de qualquer forma...)
