Swarm of 464 earthquakes hits Yellowstone National Park | Daily Mail Online

It’s low risk but low-risk doesn’t generate clicks. 🙂

Hundreds of earthquakes have hit Yellowstone National Park in the space of a week, according to experts.

A total of 464 quakes have been recorded over the past week at Yellowstone, which sits above one of the world’s most dangerous supervolcanoes.

This is the highest number of earthquakes at the park within a single week in the past five years.The recent activity has raised fears that the supervolcano is about to blow.

If it were to erupt, the Yellowstone supervolcano would be one thousand times as powerful as the 1980 Mount St Helens eruption, experts claim – although they say the risk is ‘low’.

BBC – Capital – Why you should manage your energy, not your time

Interesting approach.

Many of us will have had that sense of there just not being enough hours in the day to do everything we need to do. Tasks that should take only a few minutes can stretch into hours, all while other work mounts up.

For most, the solution is to work later into the evening or even over the weekend, which leaves many of us feeling exhausted, stressed and burned out. But what if working less were the key to getting more done?

As early as 2007, analysis demonstrated that 400-V dc distribution had advantages; Now there’s a way to implement it.


Is DC power the wave of the future for computing environments?

Power distribution in data centers used to emulate the architecture of old telephone central offices. A “rectifier” would step down and rectify the ac from the power line and use it to charge banks of batteries that provided an unregulated 48 V dc, which was distributed around the facility to run the telephone equipment in the racks.

Since at least 2007, data-center engineers have been talking about distributing 400 V dc (sometimes 380 V). Data centers are bigger and use a lot more power than telco central offices. At a minimum, higher voltage distribution would mean lower I2R losses and/or thinner power-distribution cables.

Cheap Thoughts: Time of Use for Water

Falls Lake at the worst of drought, December 9, 2007

On Saturday my family and placed four tons of grass sod in our backyard. As I fired up a sprinkler for the first time in several years (a decade, perhaps?) I thought about how much our next water bill was going to cost us. The City of Raleigh has tiered water rates, meaning everyone gets their base allotment for the same price but the price quickly jumps beyond that amount. The idea is that economics will compel water customers to conserve which is a worthy goal.

But what about the times conservation isn’t needed? Right now Falls Lake is full. The U.S. Army Corps of Engineers is releasing water from Falls Lake at a rate of 6,000 cubic feet per second, which I’ve heard is about the most it will release at any time. This onslaught of water is causing issues downstream, flooding neighborhoods that haven’t yet recovered from last month’s initial round of heavy flooding.

It doesn’t appear that conservation is an issue at the moment, so what if our water bills could reflect this? What if Raleigh residents could give The Army Corps a hand by putting that water where it could good some good: on everyone’s lawns and gardens, not just those unfortunate few who live close to the raging river? What if the City reduced water rates on a temporarily basis while the river release was underway? I know there’s more to water use than simply supply (it has to be treated, for instance) but tying water rates to our supply might make sense.

To Be a Genius, Think Like a 94-Year-Old – The New York Times

Great story on why innovation isn’t the exclusive domain of the young. The 94-year-old Dr. Goodenough continues to innovate.

In 1946, a 23-year-old Army veteran named John Goodenough headed to the University of Chicago with a dream of studying physics. When he arrived, a professor warned him that he was already too old to succeed in the field.

Recently, Dr. Goodenough recounted that story for me and then laughed uproariously. He ignored the professor’s advice and today, at 94, has just set the tech industry abuzz with his blazing creativity. He and his team at the University of Texas at Austin filed a patent application on a new kind of battery that, if it works as promised, would be so cheap, lightweight and safe that it would revolutionize electric cars and kill off petroleum-fueled vehicles. His announcement has caused a stir, in part, because Dr. Goodenough has done it before. In 1980, at age 57, he coinvented the lithium-ion battery that shrank power into a tiny package.

How to reset your body clock, and get better sleep, with hiking boots and a tent – The Washington Post

How to fix poor sleep brought on by modern technology: go camping!

Are you sick of going to bed late and waking up tired? Then grab your hiking boots and a tent. A new study suggests that a couple days of camping in the great outdoors can reset your circadian clock and help you get more sleep.

The circadian clock is an internal system that tells your body when it’s time to go to sleep and when it’s time to wake up. Scientists track this clock by measuring the amount of melatonin circulating in a person’s blood at any given time.

In a healthy sleeper, melatonin levels rise a few hours before bedtime, stay high through the night and then settle back down to daytime levels when it’s time to wake up. The period when melatonin levels are elevated is known as biological night.

In our modern society, biological night does not usually coincide with night in the natural world. Most of us stay up many hours past sunset, and we would probably sleep in many hours after sunrise if we could.

The trouble is, if your biological night begins at midnight or later, your melatonin levels may still be high when your alarm clock goes off in the morning. This leads to grogginess, and it may have other consequences, researchers say. Diabetes, obesity and heart disease have all been associated with not getting enough sleep.

Research by integrative physiology professor Kenneth Wright of the University of Colorado at Boulder found that people reset their circadian clocks by taking a six-day summer camping trip in the Rocky Mountains.

Internet everywhere

Two recent events converged in my mind. Yesterday, I attended Google’s grand opening of its Fiber Space in Raleigh, where gigabit Internet connections are the norm. And on Saturday afternoon, I was in Garner’s Southeast Regional Library to pick up Hallie and observed that all but two of the library’s Internet terminals were occupied. It made me sad that in the years since I watched a mom and her son turned away from the library when no computers were available that a shortage of Internet access is still seems to be a problem.

I hope the big-gun Internet providers like Google Fiber, AT&T, and the rest continue working to provide Internet access to the people who need it most.

‘Beyond the extreme’: Scientists marvel at ‘increasingly non-natural’ Arctic warmth – The Washington Post

Kudos to citizen-scientist Nico Sun who assembled the temperature graphs from publically-available weather data.

The Arctic is so warm and has been this warm for so long that scientists are struggling to explain it and are in disbelief. The climate of the Arctic is known to oscillate wildly, but scientists say this warmth is so extreme that humans surely have their hands in it and may well be changing how it operates.

Temperatures are far warmer than ever observed in modern records, and sea ice extent keeps setting record lows.2016 was the warmest year on record in the Arctic, and 2017 has picked up right where it left off. “Arctic extreme (relative) warmth continues,” Ryan Maue, a meteorologist with WeatherBell Analytics, tweeted on Wednesday, referring to January’s temperatures.

Veteran Arctic climate scientists are stunned.

Google Fiber Space Grand Opening

I attended the grand opening of Raleigh’s Google Fiber Space today on my lunch break. It was a good chance to check things out for myself and to say hi to some of the Googlers (and other techies) I know.

While I was there, N&O photojournalist Travis Long interviewed me about what Google Fiber means. I didn’t go there expecting to be interviewed but I always enjoy talking about the wonders of broadband.

Rules for a constitutional crisis – Medium

Excellent advice on the way forward from super-lawyer Larry Lessig.

I became a lawyer because of a story told to me about Watergate, by my uncle, Richard Cates. Cates was a lawyer from Madison. When the House started investigating Nixon, he was hired to be counsel to the House Committee on Impeachment. His job was to put together the facts supporting a case against Nixon, and convince the members of the House that those facts merited impeachment. (Working for him, just out of law school: Hillary Clinton.)

In Code and other Laws of Cyberspace, I described how he described to me the job of being a lawyer:

It is what a lawyer does, what a good lawyer does, that makes this system work. It is not the bluffing, or the outrage , or the strategies and tactics. It is something much simpler than that. What a good lawyer does is tell a story that persuades. Not by hiding the truth or exciting the emotion , but using reason, through a story, to persuade. When it works, it does something to the people who experience this persuasion. Some, for the first time in their lives, see power constrained by reason. Not by votes, not by wealth, not by who someone knows?—?but by an argument that persuades. This is the magic of our system, however rare the miracles may be.

But the part of the story he told me then that I didn’t describe there connects directly with the constitutional crisis that is brewing within America just now. Because the real magic that my uncle described to me was the effect that this work done well had on politicians. Even he was almost moved by the seriousness with which both sides considered the impeachment. There was no politics, at least as he saw it. At least with him, Democrats weren’t grandstanding and Republicans weren’t flinching from the facts they were being shown. They knew that they were engaged in the most serious job a member of Congress could have?—?because they knew that in a critical sense, the very stability of the Republic depended on them behaving as adults.
