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.'"

Could Betelgeuse Go Boom? 383

An anonymous reader writes "The answer is No. In space, nobody can hear you scream. However, it might go supernova in the near future, if it hasn't already. I wanna see that, even if it would permanently disfigure Orion. Ka freaking bam!"

Comment Still going to be around for a while (Score 2, Interesting) 794

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."

How Comic Fans & Shops Are Stereotyped 387

brumgrunt writes "Why do TV shows, such as 30 Rock, The Simpsons, Heroes, and Everybody Loves Raymond, persist in so ferevently stereotyping comic book fans and stores? Den of Geek has pulled together eight examples, with video evidence to back them up ..." Minus one point for doubling up on Malcolm in the Middle. Plus 10 points for referencing Spaced, which I hope you all have seen.

World's "Fastest" Small Web Server Released, Based On LISP 502

Cougem writes "John Fremlin has released what he believes to be the worlds fastest webserver for small dynamic content, teepeedee2. It is written entirely in LISP, the world's second oldest high-level programming language. He gave a talk at the Tokyo Linux Users Group last year, with benchmarks, which he says demonstrate that 'functional programming languages can beat C.' Imagine a small alternative to Ruby on rails, supporting the development of any web application, but much faster."

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.

I know you are trolling, but actually CUDA applications work better on Linux than on Windows. If you run a CUDA kernel on Windows that lasts longer than 5~6 seconds, your system will hang. The same will happen on Linux but then you can just disable the X server or have one card providing your graphical display and another one as your parallel co-processor.
