Can I Check Web Sites Visited by my Kids/Staff?
Posted by Philip Raymond in categories: computing, internet, policy, privacy, security, software, surveillance
Early this morning, I was asked this question at Quora. It’s a pretty basic request of network administrators, including parents, schools and anyone who administers a public, sensitive or legally exposed WiFi hot spot.
Is there a quick and easy way to view, log, or otherwise monitor the web sites visited by people on your home or office network?
Yes. It’s free and and it is pretty easy to do.
It gets a bit trickier, if the individual on your network is using a VPN service that they have configured on their device.[1] A VPN does not stop you from logging their browsing, but all of their activity will point to the VPN address instead of the site that they are actually visiting. In that case, there is another way to monitor their activity. See note #1, below.

Today in 2015: New Horizons at Pluto
Posted by Genevieve Klien in category: space travel
The small, fast-moving New Horizons spacecraft is likely to be the only Pluto mission in the lifetimes of many of us. It changed forever the way we on Earth perceive this outermost world and its moons.

Bacteria Could Help Mass-Produce Wonder Material Graphene At Scale
Posted by Genevieve Klien in categories: particle physics, sustainability
There’s no doubting that graphene, a single layer of graphite with the atoms arranged in a honeycomb hexagonal pattern, is one of science’s most versatile new materials. Capable of doing everything from filtering the color out of whisky to creating body armor that’s stronger than diamonds, graphene exhibits some truly unique qualities. However, while some mainstream uses of graphene have emerged, its use remains limited due to the challenge of producing it at scale. The most common way to make graphene still involves using sticky tape to strip a layer of atoms off ordinary graphite.
That’s something that researchers from the University of Rochester and the Netherlands’ Delft University of Technology have been working to change. They’ve figured out a way to mass produce graphene by mixing oxidized graphite with bacteria. Their method is cost-efficient, time-efficient, and sustainable — and may just make graphene a whole lot more available in the process.
“In our research, we have used bacteria to produce graphene materials on a bulk scale, and we showed that our material is conductive, and both thinner and able to be stored longer than chemically produced graphene materials,” Anne Meyer, professor of biology at the University of Rochester, told Digital Trends. “These properties demonstrate that our bacterial graphene would be well suited for a variety of applications, such as electrical ink or lightweight biosensors. Our approach is also incredibly simple and environmentally friendly compared to chemical approaches. All we have to do is mix our bacteria with the graphene precursor material, and leave them sitting on the benchtop overnight.”

Wanted: Australian mining know-how for moon, Mars missions
Posted by Klaus Baldauf in category: space travel
Washington | Australian resources industry giants such as BHP and Rio Tinto could soon play a crucial role in NASA’s Mars mission, building and operating mines on the moon to extract rocket fuel for interplanetary travel.
In an interview with The Australian Financial Review on Tuesday (Wednesday AEST), NASA’s top boss, administrator Jim Bridenstine, urged Australian mining companies to grasp the opportunity and challenge of applying the industry’s expertise in remote resource extraction to the moon.
Known inside NASA as Artemis (the twin sister of Apollo in Greek mythology) the lunar missions will rely on turning hundreds of millions of tons of mined water ice recently discovered on the moon into liquid forms of hydrogen and oxygen to power spacecraft.
Palm oil is in almost everything, and it’s responsible for huge amounts of deforestation across the globe. These guys have found a way to replace it, using nothing more than a cup of coffee. #YEARSproject
