Comment Interesting but meaningless (Score 1) 348

From a geekish point of view the idea is pretty neat. Who wouldn't like a bonsai lamp on his desk?

But using such a technology in public trees to replace street lights? Doesn't sound too good for me. What about the animals which dwell on the trees? Not only birds and squirrels, but also invertebrates, reptiles and other small mammals which have nocturnal life and depended on the absence of light to feed, to hunt, to reproduce, to be hunted, etc. This isn't Middle-Earth, they haven't evolved for an environment where leaves give off luminous glow.

Changing the environment (for worst) is not restricted to dumping tons of CO2 on the atmosphere. People haven't got that yet?

The interesting thing about this flick is that it actually has a history -- weak as it may be, I've seen worse in regular movies. The DVD even includes a 30 minutes long non-porn version of the movie in which all the porn scenes have been cut off.

This non-porn version is probably just a reordering of the DVD chapters by excluding the porn chapters, but nonetheless it's pretty interesting, it really captures the spirits of the original series.

Those results are from google.com. The Brazilian TLD for Google is google.com.br. I just did a quick search on both now and for the .com TLD I got 52.7% vs 47.3% for Rousseff, and for the .com.br TLD 54% vs 46%. Official polls run by several different media agencies were giving Rousseff with 60%+ of valid votes.

On the first turn of our major elections, when we voted for Senators, Governors and Congressmen, something similar happened. For my state a certain Senator candidate had 17% on previous public surveys and it was ranking 3rd. After the results were out he was elected with 36% and he was the 1st.

Here in Brazil such surveys and predictions are quite dangerous, to some extent they are used as manipulative tools. Most people are unfortunately uneducated and ignorant in issues concerning politics and economy and those people are likely to vote on the candidate which seems to be winning, just so they don't "lose" their vote (yes, this is not an uncommon reasoning around here, insane as it may sound). Worst of all perhaps is the fact that we are obliged to vote, it is an imposed duty. Our democracy is still an infant, and I think we are yet to reach adolescence. Some rough years to come.

Today Brazilians are electing their new President. It is the second turn of our elections so we get to choose between the two candidates for the presidential chair which were most voted in the first turn that occurred one month ago.

The candidates are Jose Serra (current opposition) and Dilma Rousseff (candidate supported by the current President). According to a simple "volumetric" serach on Google, Serra has 47% and Rousseff has 53%. These predictions are somewhat similar to what polls and public opinion surveys have been showing (reckoning only the valid votes). Tonight we will have the final results and I will be amazed if this Google prediction so to speak turns out to be more accurate than official polls.

True, but the video made me feel kinda sad. Despite being completely ignored by most people he lives in this world in his head where the current president would subject himself to a dark and moldy basement in order to get a half-assed hologram taken. Other than that, when was this documentary made? I thought someone would mention 3D TVs and stuff like that near the end when he says the world is dimensional but we seem to be content with representing it as flat.

Air Force Planning New Drone Fleet For Pakistan 240

mattnyc99 writes "With tensions high on the border, a new commander in Afghanistan, and complaints of civilian deaths from robotic US strikes in Pakistan raising anti-American sentiment, the Air Force is sketching out concepts for new robotic hitmen, reports Esquire.com. Among the new drones (which are all very small) are the Suburb Warrior (loaded with four or five mini missiles for semi-urban environments), the Sniper targeting system ("that can lock on to multiple targets, allowing a single drone pilot to coordinate the attacks of a squadron of robots"), and a backup fleet of flying buggies that act as suicide-bomber snipers. From the article: 'Picking through the dozens of systems in this briefing, many of which will be flight-tested within five years, there's a clear set of goals: build smaller, even microscopic drones with smaller weapons that can hunt in swarms and engage targets in the close quarters of urban battlefields. And hunt as soon as possible.'"

In my opinion, yes. I am an undergrad Physics student (senior) and had my first contact with Fortran in my third semester, in a course called Computational Physics I. We learned the basics of Fortran 77/90 and how to solve some numerical problems using it. We also simulated some interesting problems that amazes undergrad students such as chaotic oscillators, Magnus effect in action and a few other simple yet curious systems. I had already some programming experience, but most other students didn't. They got it quite quickly and I think this is due Fortran's simplicity.

Even if you are never going to use Fortran in your own projects, you will stumble on it now and then if you are going seriously into applied and theoretical research field. NASA, for example, has tons of production code written in Fortran and even new codes are written on it. Many many Physics and Chemistry groups around the world have their most important codes in Fortran, and sometimes they use clever hacks to make the code faster, so a minimum understanding of it is necessary. I work with a Computational Chemistry group and much of the code they still develop, even for new applications, is Fortran. It is good and solid code, they are very experienced on it, and they are not willing to change to another technology so easily.

As a first language I don't know if Fortran is the best, maybe Python or Java would be my choice in this case, but it is definitely worth learning.

Submission + - Hydraulic Analogue Computer from 1949 (americafree.tv) 2

mbone writes: In the New York Times there is an interesting story about a hydraulic analogue computer from 1949 used to model the feedback loops in the economy. According to the article "copies of the "Moniac," as it became known in the United States, were built and sold to Harvard, Cambridge, Oxford, Ford Motor Company and the Central Bank of Guatemala, among others." There is a cool 19 MB video of the computer at Cambridge University in operation. I remember that the Instrumentation Lab at MIT still had a analogue computer in its computer center in the mid-1970's, but even then it seemed archaic and now this form of computation is largely forgotten.

With 14 machines built, it must have been one of the more successful analogue computers — a supercomputer of its day. Of course, you have to wonder if it could have been used to predict our current economic difficulties.
