astroengine writes with news of SpaceX's next step in experimenting with vertical landings for rocket stages
. From the article: "Space Exploration Technologies is installing landing legs on its next Falcon 9 rocket, part of an ongoing quest to develop boosters that fly themselves back to the launch site for reuse. For the upcoming demonstration, scheduled for March 16, the Falcon 9's first stage will splash down, as usual, in the ocean after liftoff from Cape Canaveral Air Force Station in Florida. This time, however, SpaceX hopes to cushion the rocket's destructive impact into the Atlantic Ocean by restarting the Falcon 9's engine and extending landing legs that will be attached to the booster's aft section. The goal is a soft touchdown on the water."
The test is scheduled for their ISS resupply mission on March 16th
2014 (the mission also features the launch of the crowdfunded KickSat
nano nanosatellites) .Read Replies (0)

Hugh Pickens DOT Com writes "Paula Burkes reports that under legislation passed in 2007, Oklahoma students, effective this May, now must demonstrate an understanding in banking, taxes, investing, loans, insurance, identity theft and eight other areas to graduate. The intent of personal financial literacy education is to inform students how individual choices directly influence occupational goals and future earnings potential. Basic economic concepts of scarcity, choice, opportunity cost, and cost/benefit analysis are interwoven throughout the standards and objectives. 'Oklahoma has some of the strongest standards in the country,' says Amy Lee, executive director of the Oklahoma Council on Economic Education, which lobbied for and helped develop the curriculum. 'Where other states require four or five standards regarding earnings, savings and investing, Oklahoma has 14 standards including three that are state-specific: bankruptcy, the financial impact of gambling and charitable giving.' The law is designed to allow different districts to implement the curriculum in different ways, by offering instruction in various grade levels, or by teaching all the curriculum in a single class or spreading it across several courses. 'The intent of this law was always to graduate students out of high school with a strong foundation in personal financial literacy to reduce the many social ills that come from mismanaging personal finance,' says Jim Murphree. 'I cannot think of anything that we teach that is more relevant.'"Read Replies (0)

Saint Aardvark writes "If you're a Unix or Linux sysadmin, you know sudo: it's that command that lets you run single commands as root from your own account, rather than logging in as root. And if you're like me, here's what you know about configuring sudo:
1.) Run sudoedit and uncomment the line that says "%wheel ALL=(ALL) ALL".
2.) Make sure you're in the wheel group.
If you're a sysadmin, you need to stop people from shooting themselves in the foot. There should be some way of restricting use, right? Just gotta check out the man page.... And that's where I stopped, every time. I've yet to truly understand Extended Backus-Naur Form, and my eyes would glaze over. And so I'd go back to putting some small number of people in the 'wheel' group, and letting them run sudo, and cleaning up the occasional mess afterward. Fortunately, Michael W. Lucas has written Sudo Mastery: User Access Control for Real People."

An anonymous reader writes "From the Telegraph, 'He is vain, secretive, paranoid and jealous, prone to leering at young women and making frequent sexist jokes – and that's not the view of one of his many enemies, but of a friend ... A damning picture of Julian Assange ... has emerged in a detailed account by his ghostwriter. Assange behaves ... like an egotistical tyrant interested more in his own self-publicity than in changing the world. Worse still, he turns on his friends with increasing regularity ... Assange describes the Ecuadorean ambassador offering him diplomatic asylum as 'mad', 'fat' and 'ludicrous'. Even Assange's girlfriend, WikiLeaks researcher Sarah Harrison, grew increasingly frustrated at his behaviour. 'He openly chats girls up and has his hands on their a**e and goes nuts if I even talk to another guy,' she says. O'Hagan, who had hoped to find an anti-authoritarian rebel figure worthy of admiration, says he comes to regard Assange as someone who sacrificed the moral high-ground by attempting to evade trial over the rape charges.' — The Scotsman adds, 'Canongate director Jamie Byng yesterday hailed O'Hagan's account of the "impossibility of trying to ghost Assange's memoirs". He tweeted: "Andy O'Hagan's compelling, ring side account of Being (& being around) Julian Assange is smart, accurate and fair."'"Read Replies (0)

Hugh Pickens DOT Com writes "Exxon Mobile's CEO Rex Tillerson's day job is to do all he can to protect and nurture the process of hydraulic fracturing—aka 'fracking'—so that his company can continue to rake in billions via the production and sale of natural gas. 'This type of dysfunctional regulation is holding back the American economic recovery, growth, and global competitiveness,' said Tillerson in 2012 of attempts to increase oversight of drilling operations. But now Rick Unger reports at Forbes that Tillerson has joined a lawsuit seeking to shut down a fracking project near his Texas ranch. Why? Because the 160 foot water tower being built next to Tillerson's house that will supply the water to the near-by fracking site, means the arrival of loud trucks, an ugly tower next door, and the general unpleasantness that will interfere with the quality of his life and the real estate value of his sizeable ranch. The water tower is being built by Cross Timbers Water Supply Corp., a nonprofit utility that has supplied water to the region for half a century. Cross Timbers says that it is required by state law to build enough capacity to serve growing demand. In 2011, Bartonville denied Cross Timbers a permit to build the water tower, saying the location was reserved for residences. The water company sued, arguing that it is exempt from municipal zoning because of its status as a public utility. In May 2012, a state district court judge agreed with Cross Timbers and compelled the town to issue a permit. The utility resumed construction as the town appealed the decision. Later that year, the Tillersons and their co-plaintiffs sued Cross Timbers, saying that the company had promised them it wouldn't build a tower near their properties. An Exxon spokesman said Tillerson declined to comment. The company 'has no involvement in the legal matter' and its directors weren't told of Mr. Tillerson's participation, the spokesman said."Read Replies (0)
