Lockheed, SpaceX Trade Barbs

Space

Lockheed Martin and Boeing have been getting all government launch contracts for the past six years. That is, until SpaceX demonstrated they could reach the International Space Station successfully this year. Asked about the new competition brought by SpaceX, Lockheed CEO Robert Stevens made light of the younger company’s success. “I’m hugely pleased with 66 in a row from [the Boeing-Lockheed alliance], and I don’t know the record of SpaceX yet,” he said. “Two in a row?” When he was asked about the skyrocketing price of launching his sky rockets, he said, “You can thrift on cost. You can take cost out of a rocket. But I will guarantee you, in my experience, when you start pulling a lot of costs out of a rocket, your quality and your probability of success in delivering a payload to orbit diminishes.” SpaceX CEO Elon Musk was blunt about the source of the price difference between the companies: “The fundamental reason SpaceX’s rockets are lower cost and more powerful is that our technology is significantly more advanced than that of the Lockheed-Boeing rockets, which were designed last century.” The Delta IV and Atlas V rockets of Lockheed-Boeing average about $464 million per launch, while SpaceX’s Falcon 9 launches for $54 million. Its upcoming Falcon Heavy will go up for $80-125 million.

Should Hacked Companies Disclose Their Losses?

derekmead writes “By law, US companies don’t have to say a word about hacker attacks, regardless of how much it might’ve cost their bottom line. Comment, the group of Chinese hackers suspected in the recent-reported Coke breach, also broke into the computers of the world’s largest steel company, ArcelorMittal. ArcelorMittal doesn’t know exactly how much was stolen and didn’t think it was relevant to share news of the attack with its shareholders. Same goes for Lockheed Martin who fended off a ‘significant and tenacious’ attack last May but failed to disclose the details to investors and the Securities Exchange Commission. Dupont got hit twice by Chinese hackers in 2009 and 2010 and didn’t say a word. Former U.S. counterintelligence chief Joel Brenner recently said that over 2,000 companies, ISPs and research centers had been hit by Chinese hackers in the past decade and few of them told their shareholders about it. This is even after the SEC has made multiple requests for companies to come clean about cyber security breaches in their quarterly or annual earnings reports. Because the potential losses, do hacked companies have a responsibility to report security breaches to investors?”

Killer Asteroids Are Good For Life

Space

Hugh Pickens writes writes “NASA reports that according to a study by Rebecca Martin and Mario Livio asteroid collisions may have provided a boost to the birth and evolution of complex life on earth delivering water and organic compounds to the early Earth and accelerating the rate of biological evolution with occasional impacts to disrupt a planet’s environment to the point where species must try new adaptation strategies. ‘Too many asteroids, and you’ve got an unrelenting cosmic shooting gallery, raining fiery death from above,’ writes Fraser Cain. ‘Too few asteroids, and complex life might not get the raw material it needs to get rolling. Life never gets that opportunity to really shake things up and evolve into more complex forms.’ Martin and Livio suggest that the location of an asteroid belt relative to a Jupiter-like planet is not an accident. The asteroid belt in our solar system, located between Mars and Jupiter, is a region of millions of space rocks that sits near the ‘snow line,’ which marks the border of a cold region where volatile material such as water ice are far enough from the sun to remain intact. ‘To have such ideal conditions you need a giant planet like Jupiter that is just outside the asteroid belt [and] that migrated a little bit, but not through the belt,’ Livio explains. ‘If a large planet like Jupiter migrates through the belt, it would scatter the material. If, on the other hand, a large planet did not migrate at all, that, too, is not good because the asteroid belt would be too massive. There would be so much bombardment from asteroids that life may never evolve.’”

Judge Rules Defense Can Use Trayvon Martin Tweets

Privacy

theodp writes “The NY Times reports a judge in the second-degree murder case against George Zimmerman has ruled that Trayvon Martin’s school and social media records should be provided to the defense. Judge Debra S. Nelson said Martin’s Twitter, Facebook and school records were relevant in the self-defense case. In those instances, showing whether a victim ‘had an alleged propensity to violence’ or aggression is germane, the judge said. The defense also got permission for access to the social media postings of a Miami girl who said she was on the phone with Martin just before the shooting. Time to update the Miranda warning to include: ‘Anything you Tweet or post can and will be held against you in a court of law’?'”

NASA Working on Mars Menu

Mars

DevotedSkeptic writes in with a story about the work going into feeding astronauts on a mission to Mars. “The menu must sustain a group of six to eight astronauts, keep them healthy and happy and also offer a broad array of food. That’s no simple feat considering it will likely take six months to get to the Red Planet, astronauts will have to stay there 18 months and then it will take another six months to return to Earth. Imagine having to shop for a family’s three-year supply of groceries all at once and having enough meals planned in advance for that length of time. ‘Mars is different just because it’s so far away,’ said Maya Cooper, a senior research scientist with Lockheed Martin who is leading the efforts to build the menu. ‘We don’t have the option to send a vehicle every six months and send more food as we do for the International Space Station.’”

Robotics

garymortimer writes “Lockheed Martin (LMT) and LaserMotive, Inc., recently demonstrated the capabilities of an innovative laser power system to extend the Stalker Unmanned Aerial System (UAS) flight time to more than 48 hours. This increase in flight duration represents an improvement of 2,400 percent. Stalker is a small, silent UAS used by Special Operations Forces since 2006 to perform intelligence, surveillance and reconnaissance missions.”

IP Lawfirm Sues Typosquatting Security Researcher

Crime

First time accepted submitter scottbee writes “A major New York intellectual property lawfirm has filed a $1m lawsuit against domain squatter/security researcher Wesley Kenzie (aka Securikai). Kenzie registered domain names to collect misaddressed email, and then holding companies to ransom claiming he had found security vulnerabilities and would consult for five figure engagements. Lockheed Martin handled it with a simple UDRP, but the Gioconda Law Group decided instead to file a lawsuit for ‘cybersquatting, trademark infringement and unlawful interception of a law firm’s private electronic communications in violation of federal laws,’ along with a permanent injunction. Kenzie had also tried the same tactic against Rapid7′s HDMoore, but was shamed out of the domain names earlier this year.”

Pentagon Contractors Openly Post Job Listings For Offensive Hackers

Sparrowvsrevolution writes “In the wake of confirmation that the U.S. government was involved in the creation of Stuxnet and likely Flame, a look over job listings on defense contractor sites shows just how explicitly the Pentagon and the firms that service it are recruiting offense-oriented hackers. Northrop Grumman, Raytheon, Lockheed Martin, SAIC, and Booz Allen have all posted job ads that require skills like ‘exploit development,’ have titles like ‘Windows Attack Developer,’ or asks them to ‘plan, execute, and assess an Offensive Cyberspace Operation.’”

Interactive Tutorial of the Sequent Calculus

May 31st, 2012 05:48 admin View Comments

Interactive Tutorial of the Sequent Calculus by Edward Z. Yang.

This interactive tutorial will teach you how to use the sequent calculus, a simple set of rules with which you can use to show the truth of statements in first order logic. It is geared towards anyone with some background in writing software for computers, with knowledge of basic boolean logic. …

Proving theorems is not for the mathematicians anymore: with theorem provers, it’s now a job for the hacker. — Martin Rinard …

A common complaint with a formal systems like the sequent calculus is the “I clicked around and managed to prove this, but I’m not really sure what happened!” This is what Martin means by the hacker mentality: it is now possible for people to prove things, even when they don’t know what they’re doing. The computer will ensure that, in the end, they will have gotten it right.

The tool behind this nice tutorial is Logitext.
