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.

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.

Submission + - Copyright violation network in Brazilian senate

gustgr writes: "Although very concerned about issues such as child pornography on the Internet and wider use of free software throughout the country, it appears that Brazilian senators and representatives don't care too much about copyright violation matters. It was found that several computers in the Brazilian National Senate's network had access to a pool of illegal downloaded music, movies and games (Google translation to English). With just a few clicks anyone inside the internal network was able to reach a large collection of copyrighted material, varying from music by local Brazilian performers to various Hollywood blockbusters. Once this news gained force amongst Brazilian political and technological blogs, the senate's Secretary of Information removed the files (translation) and announced that an investigation is to be started in order to reveal the culprits."

Nowadays I mostly play only Go, both on the computer using KGS and on real boards when I am lucky enough to find people willing to play it. As a kid I used to spend a long time playing with my SNES, and later with N64, but then gaming consoles started getting way too expensive to fit in my budget, then I would only play on computers. Then a few years later I gave up Windows and started using exclusively Linux and BSD on my personal computers. I lost games, but found programming. Now, 10 years later, I look back and see it as a worthy deal.

Submission + - Wolfram|Alpha, the Details Behind the Prompt (infoq.com)

An anonymous reader writes: Wolfram|Alpha uses symbolic computation in an attempt to make the world's systematic knowledge computable. It does that by accepting a linguistic input not a custom set of formulas. The main components of the system are a data curation pipeline, an algorithmic computation system, a linguistic processing system, and an automated presentation system.

Submission + - Intel brings rich UI to Moblin Linux platform (arstechnica.com)

2mob writes: Intel's Linux-based Moblin operating system recently got a significant user interface overhaul. The platform's new graphical shell, which was unveiled Tuesday in a new Moblin 2 beta release, delivers top-notch usability and slick visual effects. The developers have completely reinvented the concept of virtual desktops and have replaced it with a more fluid "zone" system that makes it easier to organize how windows are grouped together. The shell also has tightly-integrated social network and messaging features, such as a built-in Twitter client and an instant messenger buddy list. Ars Technica tested Moblin beta 2 on Dell netbook and has published a comprehensive hands-on look at the new user interface.

OpenCL will hopefully help to set a solid ground for GPU and CPU parallel computing, and since it is not technically very different from CUDA, porting existing applications to OpenCL will not be a challenge. Nowadays with current massively parallel technology the hardest part is making the algorithms parallel, not programming any specific device.
