While we strongly recommend that you manage your passwords, we do not envision that you would organize the post-its scattered about your desk. Is that insulting? OK. So you have a notebook? Still not good. An Excel spreadsheet? Not bad. But where do you keep the spreadsheet? How do you protect your password list? That’s the question! The answer? Not just an answer, but 8 great benefits and an entire psycho-analysis. Without the doctor’s notebook. Read more →
Another common sci-fi scenario has just left the room.
BrainNet, created by researchers at the University of Washington, is a first of a kind.
Participants in this brain-to-brain communication network are able to communicate with each other only using their thoughts. Although at a very primitive level, this is being called thought-level social networking. Nothing between you and your tweet except the bare thought. Read more →
That bulky cuff the nurse wraps around your arm allows a quick and non-invasive measurement of your blood pressure. Because it’s my heart, I never complain that the cuff is too tight. Not even when my arm aches as a result. I simply wait for the pulse to restart, which means the release of pressure. Then come the familiar words, “You’re 130/80,” my common result.
Now if I had a significant heart problem that needed to be monitored daily, carrying around a bulky cuff for hourly testing would be cumbersome. I imagine it would be easy to “forget” such a problematic routine under a busy schedule. But why would you be placing your self under the stress of a busy schedule, if you needed to monitor your heart? You wouldn’t! So something second best, like more frequent visits to the doctor’s office, would step into the problem.
What if there was a simple stick-on patch, about the size of a postage stamp, that you could place on your neck? It’s coming. Read more →
Cryptojacking. Cryptomining. Two names for one and the same threat causing problems for your computer and your smart phone. The name “cryptojacking” comes from the ability of this threat to hide on your device and take it over. Cryptomining is the name given to indicate the reason. Your device is cryptojacked so that undesirables can use the resources on your device to mine cryptocurrencies. Not that you are interested or own cryptocurrencies. Rather, unknown to you, someone else is using your computer to gain access to the protected records, enabling financial gain dishonestly. This is a proliferating nuisance that is infiltrating Internet devices from desktop to laptop to smart phone to network server. An extensive problem! Read more →
It is a most painful exercise to change one’s password. Especially when extended to a gazillion different accounts. Just as you have begun to remember that “memorable” password you created in a moment of creative ecstasy, you find you must change it. John Kelly, of the Washington Post, wrote a clever article, What’s Code for ‘Die, Computer’? Written in 2009, Mr. Kelly explores the anguish of the your-password-expires-in-3-days countdown and comes up with his own solution. Not recommended. Except for the smiles generated.
Most systems require a password change every 90 days. 4 times a year. So you smugly use the same “new” password you have plugged into the other 99 accounts you try to keep secure. But a message pops up.
Having a different password for every account is critical to ensuring your online safety. Let us help you create a new password by generating a random password for you.
That’s not a help but a threat!
The National Cyber Security Alliance builds partnerships to implement education and awareness efforts to empower users at home, work and school. The goal is to provide the information needed to keep safe and secure online. By making all internet users aware, sensitive information is more secure. We all work together to encourage a culture of cyber security.
It makes sense that securing our online lives is a shared responsibility. Not simply depending on someone else, but working myself to know what to stay away from and how to communicate with minimal risk.
One of the awareness campaigns is Stop. Think. Connect. Check their simple tips. Read more →
If that headline seems to overstate the case – unlimited source – we are talking about the sun. More or less, it is an unlimited source. If the source runs out, there won’t be anyone around to argue the point in any case. So it is reasonable to call the sun an unlimited source. The scientific technique is what makes the source available for renewable energy.
University of Cambridge scientists have brought together two techniques to convert the energy of sunlight into storable biofuel. Using synthetic biology and artificial photosynthesis their process breaks water down into hydrogen and oxygen gases. This process is a major step in mass-producing photosynthesis cells that only use energy from the sun. Understanding the design of the elements in the process enables a controlled environment which can accelerate the process. Read more →
Is there a good, bad and ugly about batteries? Evidently. NiMH (Nickel-Metal Hydride) NiCad (Nickel-Cadmium), Li-Ion (Lithium-Ion), LiFePO4 (Lithium Iron Phosphate), Alkaline, Carbon Zinc and Lithium all have strengths that are good and weaknesses that are bad. The ugly? That’s the Carbon Zinc whose only strength is that it is inexpensive. Its ugliness lies in its low energy, low endurance. Batteries “that qualify as little more than junk” according to zbattery’s Household Battery Guide.
Then there’s the battery battle between Tesla’s Elon Musk and Amazon’s Jeff Bezos. Musk says lithium-ion batteries are the technology of the future. But Bezos is buying hydrogen stock. Will the alternative power source of hydrogen fuel cells threaten the popularity of lithium? Read more →
Going through the news flow of LinkedIN, I saw a home experiment for kids. The mother used a simple experiment to show her kids what a suction bucket was. She had an aquarium with sand covered by water. She inserted a coke can with the top cut off. Then she inserted a straw into the bottom of the can and sucked out the air trapped inside the can.
Visually, I could see the can descend deeper into the sand. When she tried to pull the can out of the sand, it was very difficult. As I watched, I thought, “This is all very interesting. But what’s it for?” I thought I understood the basic concept. But, not knowing anything about suction buckets, I couldn’t see what the application would be.
I put a comment (always a scary thing to do) saying that while I thought the experiment was very interesting I had no idea what it was for. “What’s the point?” I was asking. I had this vague feeling that after all there must be a point. Just educating the kids about sand and coke cans or how to be careful not to inhale water when removing air through a straw didn’t seem sufficiently significant for all the effort involved. After all, she had posted a video! Read more →
