According to The Planetary Society, LightSail 2 has successfully raised its orbit using solar sailing, making it the first small spacecraft to demonstrate the concept. From the report: Since unfurling the spacecraft’s silver solar sail last week, mission managers have been optimizing the way the spacecraft orients itself during solar sailing. After a few tweaks, LightSail 2 began raising its orbit around the Earth. In the past 4 days, the spacecraft has raised its orbital high point, or apogee, by about 2 kilometers. The perigee, or low point of its orbit, has dropped by a similar amount, which is consistent with pre-flight expectations for the effects of atmospheric drag on the spacecraft. The mission team has confirmed the apogee increase can only be attributed to solar sailing, meaning LightSail 2 has successfully completed its primary goal of demonstrating flight by light for CubeSats.
The milestone makes LightSail 2 the first spacecraft to use solar sailing for propulsion in Earth orbit, the first small spacecraft to demonstrate solar sailing, and just the second-ever solar sail spacecraft to successfully fly, following Japan’s IKAROS, which launched in 2010. LightSail 2 is also the first crowdfunded spacecraft to successfully demonstrate a new form of propulsion. The mission team will continue raising LightSail 2’s orbit for roughly a month, until the perigee decreases to the point where atmospheric drag overcomes the thrust from solar sailing. During the orbit-raising period, the team will continue optimizing the performance of the solar sail.

An anonymous reader shares a report from The Guardian about the questionable decision in the 1950s to get rid of Sydney’s trams in favor of private cars. From the report: In the late 1950s Sydney ripped up its tram network, once one of the largest in the world. Nearly 1,000 trams — some only a few years old — were rolled to the workshops in the city’s eastern suburbs and stripped of anything that could be sold, before being unceremoniously tipped on their sides, doused with sump oil and set ablaze. Barely a decade before its closure, Sydney’s tram system had carried 400 million passenger journeys a year on a network of more than 250km, primarily serving the eastern, southern and inner-west suburbs, and stretching as far north as Narrabeen at its peak. But the explosion of car traffic in the postwar years persuaded the New South Wales government that urban freeways were the way of the future (the first in Australia, the Cahill Expressway, opened in 1958), and trams were an impediment to that vision.
The destruction of the network from the mid-50s was swift and brutal. In 1958 the bizarre castellated Fort Macquarie depot at Circular Quay was demolished to make way for the Opera House, and the lines along George Street were torn up. The last Sydney tram ran on 25 February 1961 from Hunter Street to La Perouse (along much of the same route now being rebuilt), packed to the rafters and greeted by crowds of people, before it joined the dismal procession to “burning hill” at Randwick. Mathew Hounsell, a senior research consultant at the Institute for Sustainable Futures at the University of Technology, Sydney, has called the destruction of the network “the largest organized vandalism in our nation’s history.” He says the decisions made in the 50s had a disastrous long-term effect. “When the trams were removed from Sydney, mass transport patronage plummeted and private car usage soared. Our space-saving trams were replaced with ever-more space-hungry cars, causing ever-worsening traffic. That wasn’t how the planners saw it at the time. They were strongly swayed by powerful international influences, which chimed with the unstoppable rise of private car ownership in Australia. The trams are slowly returning, as the city painfully rebuilds a tiny part of its old system. “The construction of 12.8km of light rail from Circular Quay to Randwick and Kingsford will cost $2.7 billion at the latest estimate, has caused untold misery to shops and other businesses in its path and will be almost a year overdue by the time even the first section is open,” the report says.
“The new line hardly represents a fundamental shift in Sydney’s transport thinking, coming as it does alongside the vast ‘congestion-busting’ WestConnex freeway project, and further investment in metro rail (a separate light rail link is also under construction at Parramatta). But it is a reminder that the city might have looked very different today but for the decision taken in the 1950s — and ruthlessly carried out — to prioritize motor transport.”

SSH is an every-day tool of any Linux System Administration job. It is an easy and secure way to access remote machines on the network, transfer data and execute remote commands. Apart from interactive mode, there are many tools exist that enable automation of remote tasks that also rely on the existing ssh server/client architecture. For one such tool, you can read about ansible on Ubuntu for example. You can also find many implementations of the ssh client, but what about accessing the abilities ssh provides from code?

Researchers from Tsinghua University in China and University of California, Berkeley, have developed a new kind of soft robot that looks like a bent strip of paper, but is able to move at 20 body lengths per second and survive being stomped on. The robot has been presented in the current issue of Science Robotics. IEEE Spectrum reports: This prototype robot measures just 3 centimeters by 1.5 cm. It takes a scanning electron microscope to actually see what the robot is made of — a thermoplastic layer is sandwiched by palladium-gold electrodes, bonded with adhesive silicone to a structural plastic at the bottom. When an AC voltage (as low as 8 volts but typically about 60 volts) is run through the electrodes, the thermoplastic extends and contracts, causing the robot’s back to flex and the little “foot” to shuffle. A complete step cycle takes just 50 milliseconds, yielding a 200 hertz gait. And technically, the robot “runs,” since it does have a brief aerial phase.
The researchers also put together a prototype with two legs instead of one, which was able to demonstrate a potentially faster galloping gait by spending more time in the air. They suggest that robots like these could be used for “environmental exploration, structural inspection, information reconnaissance, and disaster relief,” which are the sorts of things that you suggest that your robot could be used for when you really have no idea what it could be used for. But this work is certainly impressive, with speed and robustness that are largely unmatched by other soft robots. An untethered version seems possible due to the relatively low voltages required to drive the robot, and if they can put some peanut-sized sensors on there as well, practical applications might actually be forthcoming sometime soon.

Cisco has agreed to pay $8.6 million to settle a claim that it sold video surveillance software it knew was vulnerable to hackers to hospitals, airports, schools, state governments and federal agencies. SFGate reports: The tech giant continued to sell the software and didn’t fix the massive security weakness for about four years after a whistleblower alerted the company about it in 2008, according to a settlement unsealed Wednesday with the Justice Department and 15 states as well as the District of Columbia. Hackers could use the flaw not just to spy on video footage but to turn surveillance cameras on and off, delete footage and even potentially compromise other connected physical security systems such as alarms or locks – all without being detected, according to Hamsa Mahendranathan, an attorney at Constantine Cannon, which represented whistleblower James Glenn. The settlement marks the first time a company has been forced to pay out under a federal whistleblower law for not having adequate cybersecurity protections.
