Submission + - The First Airplane on Mars

braindrainbahrain writes: Undergoing research by NASA, the Preliminary Research Aerodynamic Design to Land on Mars, or Prandtl-M (not-so-coincidentally named after German aeronautical engineer Ludwig Prandtl) program is developing an airfoil with the ultimate goal of flying in the Martian atmosphere. The program has flown 12-ft. span models, the Prandtl-D1 and -D2, in Earth's atmosphere to prove that the flying wing design could overcome adverse yaw effects without including a tail. A larger 25 ft. model will be tested shortly and further tests call for prototypes to be balloon dropped at 85,000 feet and later at 115,000 feet to simulate Martian atmospheric density. If all goes well, it could be deployed from a cubesat container after hitching a ride to Mars with a rover in 2022.

Voyager's Golden Record For Aliens Now Available On SoundCloud 57 57

An anonymous reader writes: For years you've been able to listen to the sounds recorded on the golden records carried by the twin Voyager spacecraft online but NASA just made it a bit easier. The orginization just uploaded the recordings to SoundCloud. Now you can listen to a continuous stream of clips instead of clicking back and forth to hear the different tracks.

Comment Recruitment vs.Retention (Score 1) 473 473

This is only one of many efforts on going to recruit girls into tech, but these efforts fail to address the retention problem. How do you keep women in the field once they start working? Perhaps Google and other major companies should provide better salary or benefits so the women don't leave. Or is it easier to make tax deductible contributions to programs such as the one in TFA?

It's interesting that retention is one of the key problems the NCWIT calls out in their study, where they claim a 56% departure rate of women from the field, and yet they have no solutions to offer.

Submission + - Russian troops traced to Ukrainian battlefields through social media

wienerschnizzel writes: Vice News released a report on how they were able to trace a member of the regular russian army from his base near the Ukriainian border towards the battlefields in the contested territory in eastern Ukraine and back to his home in Siberia using the pictures he uploaded on his social media profile.

The methodology used is based on a report by the Atlantic Council think tank released earlier this year, that asserts that information on the movement and operations of the regular russian troops can be easily gathered from publicly available sources (such as the social media).

The russian government still denies any involvement of russian troops in the fights in Ukraine.

Submission + - Jeb Bush Skeptical Of Reports That The H-1B Program Affects US Workers 1 1

theodp writes: ComputerWorld's Patrick Thibodeau reports that Republican presidential candidate Jeb Bush does not exactly come across as supportive or sympathetic to displaced U.S. IT workers. Asked to respond to recent stories about companies using H-1B visas to displace American workers with foreign tech labor, Bush said, "I’ve actually seen it on Fox, three or four times, this subject. I’ve been curious to know what the full story is. ... Sometimes you see things in the news reports, you don’t get the full picture. Maybe that’s the case here." Perhaps Jeb has gotten too close to the reality distortion field of Mark Zuckerberg's PAC, whose backers include Zuck Pal Joe Green (who nixed the idea of giving jobs to "just sort of okay" U.S. workers), Lars Dalgaard (whose message to laid-off IT workers was "you don't deserve the job"), and CEO Hadi Partovi (who informed journalists that "H-1Bs in CS rarely displace [American tech workers]").

FAA Licensed Parachute Rigger here ("License to kill", lol).

Parachutes don't just unfold, they actually deploy in a very controlled fashion. All it takes is something to initiate the sequence. In human parachutes, a pilot chute is released, which pulls out a deployment bag. The bag in turn does not open until suspension lines are stretched, and once the canopy is released from the bag, it inflates due to the difference in static air pressure within. vs dynamic air pressure outside (Bernoulli's principle). There are further mechanisms to slow down deployment in order to control the deceleration and opening shock (important for human well being). Problems occur if things happen out of sequence, or if the parachute is structurally unsound.

I can't speak for the system NASA is using, but I expect there already is a unit to "unfold" the parachute, and it is all part of the parachute system already.

Submission + - Teen hires hacker to take down school district IT systems->

An anonymous reader writes: A 17-year old boy from Idaho has been accused of paying a hacker to launch DDoS attacks against his school district. The teen reportedly hired a third party to organize a week’s worth of distributed denial-of-service campaigns this month against the West Ada school district – the largest educational district in the state. The cyberattacks affected networks at all 52 schools including payroll, online textbooks, virtual teaching and standardized testing. At the time of the hacking many students were undertaking Idaho Standard Achievement Testing online. The DDoS attacks caused the school systems to lose the test and results data and students were required to re-sit their exams multiple times. According to a report by KTVB-TV News, the teen has been arrested and may face State and Federal computer crime felony charges. If the unnamed student is found guilty he is likely to have to serve up to 180 days in juvenile prison. The suspect has also been suspended from Eagle High and risks potential expulsion. The minor’s parents are being held financially responsible for the damage caused by the attacks.

Comment Re:Sagan? Don't you mean Clarke? (Score 2) 52 52

I admire Clarke as much as anybody here, but he admits he did not invent the geostationary orbit (though he was the first to suggest using the orbit for communications satellites). The idea had been proposed as early as the 19th century by Tsiolkovsky. Citation available here (paywalled, sorry, but you can get the gist from the abstract).

Submission + - MAME Changing License to Fully Libre One

jones_supa writes: The source code of MAME (Multiple Arcade Machine Emulator) has long been freely available, but it's never been completely libre. Instead it's been available under a modified BSID license that prohibits, among other things, commercial use of the code. MAME engineer Miodrag Milanovic explains that such license was put in place to deter "misuse of MAME in illegal ways," but it also kept legitimate commercial entities doing business with the software. Examples of such could be museums that charge entry fees from using MAME in their exhibits, or copyright holders rereleasing vintage games encapsulated inside MAME. Now the project wants to go fully open. Milanovic continues: "Our aim is to help legal license owners in distributing their games based on MAME platform, and to make MAME become a learning tool for developers working on development boards." As of yet, there are no specific details about the new license.
