Long-time Slashdot reader RoccamOccam quotes Interesting Engineering: The United States Space force now has offensive power, though it might not be the massive orbiting weapons system that you're envisioning.

The new weapons system delivered to the space force is a jammer type array that can prevent military or intelligence combatants from accessing their military satellites. This functionality allows the space force to neutralize orbiting satellites in a matter of minutes.
The International Business Times adds that "In a previous report, the U.S. identified Russia and China as potential threats to the country's presence in space.

"The U.S. Space Force's recently confirmed that it already has 16 units of its new ground-based offensive weapon system. The agency also reported that it has already started working on the system's successor..."

Microsoft CEO Satya Nadella is defending the company's $479 million contract with the Pentagon to supply augmented reality headsets to the U.S. military. "We made a principled decision that we're not going to withhold technology from institutions that we have elected in democracies to protect the freedoms we enjoy," he told CNN Business at Mobile World Congress. "We were very transparent about that decision and we'll continue to have that dialogue [with employees]," he added during the exclusive interview. From the report: Microsoft was awarded the contract to supply "Integrated Visual Augmentation System" prototypes to the U.S. military in November. The company could eventually deliver over 100,000 headsets under the contract. Microsoft's HoloLens augmented reality technology allows users to see the world around them, but with virtual graphics overlaid. The Israeli military, which has taken delivery of some HoloLens headsets, says the technology can be used to help commanders visualize the battlefield and field medics to consult doctors. According to procurement documents, the U.S. military is seeking a single platform that provides its forces with "increased lethality, mobility and situational awareness" in combat. Microsoft employees have recently circulated a letter addressed to Nadella and Brad Smith, the company's president and chief legal officer, arguing that the company should not supply its HoloLens technology to the U.S. military. "It's not about taking arbitrary action by a single company, it's not about 50 people or 100 people or even 100,000 people in a company," he said. "It's really about being a responsible corporate citizen in a democracy."

yyzmcleod writes "Building on the work of last year's bionic creation, the Smart Bird, Festo announced that it will literally launch its latest creation, the BionicOpter, at Hannover Messe in April. With a wingspan of 63 cm and weighing in at 175 grams, the robotic dragonfly mimics all forms of flight as its natural counterpart, including hover, glide and maneuvering in all directions. This is made possible, the company says, by the BionicOpter's ability to move each of its four wings independently, as well as control their amplitude, frequency and angle of attack. Including its actuated head and body, the robot exhibits 13 degrees of freedom, which allows it to rapidly accelerate, decelerate, turn and fly backwards."

snydeq writes "Microsoft Excel has a zero-day vulnerability that attackers are exploiting on the Internet, according to security vendor Symantec. The problem affects Excel 2007 both without and with Service Pack 1, according to an advisory on SecurityFocus, and other versions going back to Excel 2000. The program's vulnerability can be exploited if a user opens a maliciously crafted Excel file, allowing a hacker to leave a Trojan horse on the infected system."

Ostracus writes with news of another contender for a next-gen device suitable for displaying a newspaper page. It's very thin but weighs a bit more than a Kindle. "Plastic Logic, a spin-off company from the Cambridge University's Cavendish Laboratory, has recently released its design of a future electronic newspaper reader. This lightweight plastic screen copies the appearance, but not the feel, of a printed newspaper. This electronic paper technology was pioneered by the E-Ink Corporation and is used in the current generation Sony eReader and Amazon.com's Kindle. Plastic Logic's device, yet to be named, has a highly legible black-and-white display and a screen more than twice as large compared to current versions available on the market."

MojoKid writes "Today marks the official launch of Intel's new Core i7 processor, the most major overhaul of Intel's core processor architecture since the release of their Core 2 design. As has been reported, the Core i7 is a major departure from Intel's aging Front Side Bus architecture of old, now replaced by Intel's QPI (Quick Path Interconnect) serial links. This 20 lane bi-directional (40 lanes total) point-to-point connection provides 6.4 GT/s of bandwidth and scalability for future multi-socket designs as well. In addition, the Core i7 now has an integrated triple channel memory controller offering over 3X the bandwidth of the previous Core 2 architecture with DDR3 system memory. Though the product is set to ship in volume later this month, the early benchmark numbers show Intel's new chip is markedly faster clock-for-clock versus their previous generation CPU and much faster than anything AMD has out currently."

justme8800 writes "The DSi has a bigger screen, an SD card expansion, a 0.3 megapixel camera, is thinner (no GBA slot), and has improved audio. To be released in Japan on November 1st, everywhere else sometime in 2009."

Roland Piquepaille writes "Wind power is one of the world's fastest growing electric energy sources, but as wind is intermittent, a single wind farm cannot deliver a steady amount of energy. This is why scientists at Stanford University want to connect wind farms to develop a cheaper and more reliable power source. Interconnecting wind farms with a transmission grid should reduce the power swings caused by wind variability and provide a somewhat constant and reliable electric power (or 'baseload' power) provided by other power plants."

daevux writes "CNN is reporting that French engineer Pascal Cotte has discovered interesting details of the history of Da Vinci's Mona Lisa from a 240-megapixel scan of the artwork in various frequencies. Cotte surmises that the painted figure's eyebrows and eyelashes probably disappeared due to poor cleaning at some point in the past. He believes he can reconstruct the painting's original skin tones."

ras_b asks: "I don't pay attention to politics at all, and so I will not be voting in today's elections. My family has been telling me that this is a mistake and I should vote anyway, partly because I have slightly conservative views which agrees with their political outlook. My reasoning is that since I am totally uninformed, I shouldn't vote. I don't want to vote Republican or Democrat, only to find out later I totally disagree with something a candidate stands for. So, here's my dilemma and my question: Is an uninformed vote better than no vote?" This issue is touched upon in a posting by Ezra Klein, of the The American Prospect, who disagrees, arguing against a similar assertion by Greg Mankiw, from a suppressed Fortune article. Greg says: "Sometimes...the most responsible thing a person can do on election day is stay at home ... If you really don't know enough to cast an intelligent vote, you should be eager to let your more informed neighbors make the decision." What do you think?
