Simpler "Hello World" Demonstrated In C 582

Posted by kdawson from the non-obfuscated dept.
An anonymous reader writes "Wondering where all that bloat comes from, causing even the classic 'Hello world' to weigh in at 11 KB? An MIT programmer decided to make a Linux C program so simple, she could explain every byte of the assembly. She found that gcc was including libc even when you don't ask for it. The blog shows how to compile a much simpler 'Hello world,' using no libraries at all. This takes me back to the days of programming bare-metal on DOS!"

Submission + - TiVo introduces Premiere & Premiere XL DVRs (itworld.com)

Submitted by Anonymous Coward
An anonymous reader writes: TiVo is back in the news after it held a press event tonight introducing its new TiVo Series4 digital video recorders.

Two models were unveiled, the TiVo Premiere and Premiere XL. The Premiere lists for $299 and stores 45 hours of HD programming on a 320 gig drive. The $499 XL pushes the storage to 150 hours of programing on a terabyte of drive space, and adds THX certification. Both models feature an all-new interface, built in Flash, which opens the door to 3rd party apps. Flash games on our TV? Maybe. Both also support up to 1080P output. Other new features include an official 30-second scan and a capacity meter.

Submission + - Malware Analysis With Greg Hoglund (net-security.org)

Submitted by Anonymous Coward
An anonymous reader writes: In an interview with HNS, Greg Hoglund, the author one of the first network vulnerability scanners, discusses the challenges anti-malware vendors face in this rapidly evolving threat landscape. He explains how virtualization has changed the way how researchers analyze malware and offers insight into upcoming threats. Greg comments: "One of the greatest challenges is attribution: figuring out not only who wrote the malware, but also who bought and paid for it, and who is operating it. As a whole, the security industry needs to start focusing more on the human threat. The malware is just a tool — the real threat is the human who operates it."

Spectrum of Light Captured From Distant World 32

Posted by Soulskill from the what-are-you-made-of dept.
An anonymous reader writes with this excerpt from Cosmos: "Astronomers have made the first direct capture of a spectrum of light from a planet outside the Solar System and are deciphering its composition. The light was snared from a giant planet that orbits a bright young star called HR 8799 about 130 light-years from Earth, said the European Southern Observatory (ESO). ... The find is important, because hidden within a light spectrum are clues about the relative amounts of different elements in the planet's atmosphere. 'The features observed in the spectrum are not compatible with current theoretical models,' said co-author Wolfgang Brandner. 'We need to take into account a more detailed description of the atmospheric dust clouds, or accept that the atmosphere has a different chemical composition from that previously assumed.' The result represents a milestone in the search for life elsewhere in the universe, said the ESO. Until now, astronomers have been able to get only an indirect light sample from an exoplanet, as worlds beyond our Solar System are called. They do this by measuring the spectrum of a star twice — while an orbiting exoplanet passes near to the front of it, and again while the planet is directly behind it. The planet's spectrum is thus calculated by subtracting one light sample from another."

Ocean-Crossing Dragonflies Discovered 95

Posted by samzenpus from the incredible-journey dept.
grrlscientist writes "While living and working as a marine biologist in Maldives, Charles Anderson noticed sudden explosions of dragonflies at certain times of year. He explains how he carefully tracked the path of a plain, little dragonfly called the Globe Skimmer, Pantala flavescens, only to discover that it had the longest migratory journey of any insect in the world."

IDEs With VIM Text Editing Capability? 193

Posted by timothy from the one-keybinding-to-rule-them-all dept.
An anonymous reader writes "I am currently looking to move from text editing with vim to a full fledged IDE with gdb integration, integrated command line, etc. Extending VIM with these capabilities is a mortal sin, so I am looking for a linux based GUI IDE. I do not want to give up the efficient text editing capabilities of VIM though. How do I have my cake and eat it too?"

Programmable Quantum Computer Created 132

Posted by Soulskill from the four-out-of-five-ain't-bad dept.
An anonymous reader writes "A team at NIST (the National Institute of Standards and Technology) used berylium ions, lasers and electrodes to develop a quantum system that performed 160 randomly chosen routines. Other quantum systems to date have only been able to perform single, prescribed tasks. Other researchers say the system could be scaled up. 'The researchers ran each program 900 times. On average, the quantum computer operated accurately 79 percent of the time, the team reported in their paper.'"
