Aluminum Can Story


Quote
This aluminum can, named Miles, is here to tell you a thing or two about how far he travels to do his job. He's exhausted!

A charming animation that really drives home the point that we need to be more aware of how much energy is wasted in the production and transportation of goods we use everyday, and what we can be doing instead.

Book of Proverbs

From Wikipedia, the free encyclopedia

"Proverbs" translates the Hebrew word mashal, but "mashal" has a wider range of meaning than the short catchy sayings implied by the English word. Thus, while roughly half the book is made up of "sayings" of this type, the other half is made up of longer poetic units of various types. These include "instructions" formulated as advice from a teacher or parent addressed to a student or child, dramatic personifications of both Wisdom and Folly, and the "words of the wise" sayings, longer than the Solomonic "sayings" but shorter and more diverse than the "instructions".[7]

The Book of Proverbs (Hebrew: מִשְלֵי, Míshlê (Shlomoh), "Proverbs (of Solomon)") is the second book of the third section (called Writings) of the Hebrew Bible and a book of the Christian Old Testament.[1] When translated into Greek and Latin, the title took on different forms: in the Greek Septuagint (LXX) it became Παροιμίαι Paroimiai ("Proverbs"); in the Latin Vulgate the title was Proverbia, from which the English name is derived.

Proverbs is not merely an anthology but a "collection of collections" relating to a pattern of life which lasted for more than a millennium.[2] It is an example of the Biblical wisdom tradition, and raises questions of values, moral behaviour, the meaning of human life, and right conduct.[3] The repeated theme is that "the fear of God (meaning submission to the will of God) is the beginning of wisdom".[4] Wisdom is praised for her role in creation; God acquired her before all else, and through her he gave order to chaos; and since humans have life and prosperity by conforming to the order of creation, seeking wisdom is the essence and goal of the religious life.[5]

Agelbert NOTE: Great scientists who pioneered the scientific method, unlike many present scientists, who worship at the atheist Darwinian altar, knew that Nature, that complex and magnificently ordered life matrix we observe, admire and totally depend on for our survival, also called the biosphere, must be obeyed. Francis Bacon, a wise man who WAS NOT an atheist, understood the message of Proverbs quite well.


FRANCIS BACON: GOD AND ATHEISM

Sir Francis Bacon was critical in the development of the scientific method, and, thus, being a philosophical/scientific giant, atheists have attempted to recruit him as a supporter of unbelief. Again they do so in vain, as Bacon made his religious views quite clear in some of his works, and they are clearly reflective of Christian beliefs. Ironically, he also expressed his disdain for atheism, as shown below.

Quote
"It is true, that a little philosophy inclineth man's mind to atheism; but depth in philosophy brings about man's mind to religion: for while the mind of man looketh upon second causes scattered, it may sometimes rest in them, and go no further; but when it beholdeth the chain of them confederate and linked together, it must needs fly to Providence and Deity."(Bacon, 64)

“They that deny a God destroy man's nobility; for certainly man is of kin to the beasts in his body; and, if he be not of kin to God by his spirit, he is a base and ignoble creature.” (Bacon, 67)

“It is better to have no opinion of God at all, than such an opinion as is unworthy of him: for the one is unbelief the other is contumely; and certainly superstition is the reproach of the Deity.” (Bacon, 68)

New Inventions / Aircraft for launching space vehicles
« on: June 01, 2017, 05:52:22 pm »
World's largest airplane rolled out for the first time

Even if you had been allowed to kick the tires as the world's largest airplane was rolled out for the first time Wednesday, it might have taken you a while.

Stratolaunch -- which is designed to release rockets that will carry satellites into space -- has a 385-foot wingspan, features six engines used by the Boeing 747, stands 50 feet tall and can carry more than 500,000 pounds of payload.

And it has those 28 wheels.  :o  ;D

The twin-fuselage aircraft, the baby of Microsoft co-founder Paul Allen, was pulled out of its Mojave Air and Space Port hangar in California to begin fueling tests -- the first of many ground tests.

Jean Floyd, Stratolaunch's chief executive officer, said the goal is to have a launch demonstration as early as 2019.


"Over the coming weeks and months, we'll be actively conducting ground and flight line testing at the Mojave Air and Space Port," Floyd said in a statement. "This is a first-of-its-kind aircraft, so we're going to be diligent throughout testing and continue to prioritize the safety of our pilots, crew and staff."

The Ukrainian-built Antonov An-225 is longer than the Stratolaunch.

While the Stratolaunch has the biggest wingspan, the six-engine Antonov An-225 cargo jet -- which was originally designed to carry a Soviet version of the space shuttle -- is longer. Stratolaunch is 238 feet long while the length of the An-225 is about 275 feet.

Also, aviation mogul Howard Hughes' legendary H-4 "Spruce Goose," which flew only once in 1947, has an enormous wingspan of 320 feet -- not as wide as the Stratolaunch.

Allen, owner of the NBA's Portland Trail Blazers and the NFL's Seattle Seahawks, has written about his desire to see more use of low Earth orbit without breaking the bank.

"With aircraft-like operations, our reusable launch platform will significantly reduce the long wait times traditionally experienced between the construction of a satellite and the opportunity to launch it into space," he wrote last year.

Stratolaunch will take off from a runway. It will fly to the approximate cruising altitude of a commercial airliner before launching a launch vehicle. "As the launch vehicle rockets into orbit, Stratolaunch will fly back to a runway landing for reloading, refueling and reuse," Allen says.


Allen's Vulcan Aerospace has worked with aerospace pioneer Burt Rutan's company, Scaled Composites, on the ambitious project.

The duo collaborated on the launch of SpaceShipOne in 2004.

Allen isn't the only US billionaire with the dreams and pockets big enough to take on space.

Jeff Bezos, the Amazon CEO, and Elon Musk, the Tesla and SpaceX CEO, have distinguished themselves as the must-watch innovators pushing hardest to bring the future to us today.

In late March, SpaceX made history by successfully launching a used rocket into space. And the company plans to fly two customers around the moon in 2018. It's already delivered satellites and has made resupply trips to the International Space Station.

Like Musk, Bezos wants to reuse rockets to drive down the cost of space travel. But for the time being, Blue Origin is mostly interested in conducting suborbital flights for tourists.

Agelbert NOTE: What People should know about the Replace Exclusive OR Instruction (RXOR) and Hackers.


The page contains images that come from the domain "somecards.com" which is presumably on Symantec's blacklist for hosting malicious .jpg images.
This blanket approach is too broad, giving false positives, but you can never be too careful, especially if you are using a Windows OS.


In regard to ensuring careful attention to potential attacks, for once, we agree. 

I programmed a mainframe air traffic control computer for several years. I was one of the few who could program in machine code. That means I am an expert at using Boolean algebra (denoting a system of algebraic notation used to represent logical propositions, especially in computing and electronics.) to talk directly with a computer. What does that have to do with this discussion?

I know, for example, that the RXOR instruction (that ALL COMPUTERS USE ROUTINELY)  is a toggle switch to completely reroute a program path a certain way, and then when the same key sequence is made, reroute it back. THAT is one of the FEW ways that hackers use to do their thing. Yes, I'm sure you know that. But I am bringing it to the fore here  so readers can understand that hacking is not some big mysterious thing for math "wizards"; it is a way for devious individuals of average, not superior, intelligence to try to STEAL from honest people. 

ALL computers MUST run in machine language, regardless of what "high order" language they use to interface human speak commands about math and labels to the machine language of binary bit coding. The only nuances in machine language (bit pattern the hardware understands) come from the size of a "word" (this determines where to set the far left bit when a "word" is a negative number) and whether you use octal or hexadecimal numbering. But in the end, it's all  LA(load accumulator) followed by other instructions like shift left so many bits or shift right so many bits, OR, XOR, RXOR, AND, NOT, SA (store in the accumulator), jump to label contents (address) if flag is set or don't jump if the flag is not set. etc.

The point is that hackers can ONLY get into your stuff by pushing some code into a program branch that is routinely used. THAT'S IT. They make a big deal about "viruses" and "malware" and "ransomeware" and "phishing" (and so "I am the greatest and can steal you blind so be afraid" on braggadocio), but it's all MAINLY about the RXOR.

The RXOR can, by jumping to a subroutine that zeroes out multiple memory locations, effectively wipe out giant swaths of code, if that's what you want to do, AND LEAVE NO TRACE that it was done. But they do that only when they want to crash your system without leaving evidence you can analyze in a post crash dump (trigger a Store zeroes instruction to the area the they reprogrammed).

The BASTARDS that do hacking these days do not really want to crash your system; they want to WATCH what you do in order to steal you blind. So, they insert a RXOR to, in nanoseconds, store some of your activity and rapidly return to your normal routine.

What they call "worms" and "viruses" are simply a step by step process to to get into what is called "protected" memory (read only) and WRITE something into it. That "something" is usually a RXOR (replace exclusive or) instruction that sends your program to a quiet key logger and back. They can be real "sophisticated" and put timers for DOING STUFF at certain dates or when certain activity is detected. It is all quite entertaining to unethical bastards that enjoy this sort of thing.

So, yeah, you can be assured that I will ALWAYS be VERY careful.  8)

Jim Rogers It s Time to Prepare MAY 2017 will be bad for the dollar, US economy & stock market

Jim Rogers It s Time to Prepare MAY 2017 will be collapse for the dollar, US economy & stock market.

Could be starting. 372 points sounds like a lot, but it's only 1.78% now. Not a crash, but maybe topping. All the WS bears are saying a Trump impeachment might crash the market. Some others are saying the cyber attack might do it. I don't think we're ready for the Big One yet, but I dunno. Stocks have been way overvalued for years.

Yep. My wife and I had a discussion about this from the view that Trump is technically in control of the plunge protection ex nihilo money creating counterfeiters at the Fed who jack up stocks when they fall beyond "acceptable" limits.

I said that TPTB are NOT going to save Trump's arse IF they want him to go down, which means the long overdue massive correction (as anybody that has looked at the ridiculous valuations and debt to equity ratios of the can see are historically unsustainable harbingers of a plus 10% correction, if not a crash). IOW, tomorrow will be the TELL. Right now Trumpy is yelling his head off telling at his team to GET THOSE STOCKS UP!

If the plunge protection team says "the dog ate their market software lunch" ;)  and they cannot stop the "correction" because they, uh, can't buy gazillion futures before the market opens or/and high speed pump buy bids every time indexes begin tanking to stop the red ink, then the next stop is the "automatic" trading stop brake within the markets. Again, if Wall Street has decided to dump Trump and take their chances with pseudo Christian stuffed shirt Pence, those brakes won't be too "effective".   

My wife said that Trump has all that figured out and does NOT want Pence to replace him if TPTB game convinces Trump that they are out to GIT him out of the White House. She thinks that Trump will try to get Pence "removed" through resignation or "lead poisoning" ;) so that Trump can shove Jared in there before Trump is impeached so Trump can be "pardoned in advance" by Jared (just like Ford did to Nixon).

It's an intriguing theory with some heavy duty spiritual connotations because Jared is the 666 building guy that (although you think this is bullshit, I think it very well might be true) has every indication of being the Anti-Christ predicted in the Book of Daniel, Revelation and the Gospels.

The rest of this week will be very informative for those with the wisdom to understand the unfolding of these events.

Study finds Apple Watch can detect heart problems with 97% accuracy - A wearable could save your life 

 By Rob Thubron on May 12, 2017, 10:00 AM

Fresh from the news that its Apple Watch has helped the Cupertino company oust Fitbit as the world’s top wearables vendor, a new study suggests the device could have an unexpected use: Detecting abnormal heart rhythms.

A study by researchers from the University of San Francisco presented at Heart Rhythm 2017 reveals that the heart sensor built into the Apple Watch could be used to detect conditions like arrhythmia and atrial fibrillation (AF) with 97 percent accuracy.

Over the course of several months, the researchers gathered data from 6158 users of the Cardiogram app for the Apple Watch. 200 of the subjects had been diagnosed with paroxysmal atrial fibrillation. The engineers used the data to feed a deep neural network that learned to distinguish between a healthy heartbeat and AF.

The system was tested on 51 hospital patients set to undergo cardioversions, a procedure that restores the heart’s normal rhythm. By wearing the Watch and using the app for 20 minutes before and after the operations, it was found that the AI correctly detected AF 97 percent of the time.

“Our results show that common wearable trackers like smartwatches present a novel opportunity to monitor, capture and prompt medical therapy for atrial fibrillation without any active effort from patients,” Dr. Gregory Marcus, Director of Clinical Research at UCSF’s Division of Cardiology, said in a statement.

2.7 million Americans suffer from AF, according to the American Heart Association. It leads to blood clots, stroke, heart failure and other heart-related complications. With the illness being quite difficult to diagnose, wearables like the Apple Watch could help save lives.

“While mobile technology screening won’t replace more conventional monitoring methods, it has the potential to successfully screen those at an increased risk and lower the number of undiagnosed cases of AF,” Marcus added.

How much accurate would be an Apple watch versus a Fitbit watch with HR? I'm wondering because this has been extremely useful for tracking a lot of different activities throughout the day, even if you are not a fit enthusiast or just a casual guy who wants to set some goals for the day.

"How much accurate would be an Apple watch versus a Fitbit watch with HR?"

That's exactly what I was wondering because as long as they both have the hardware to track the person's heartbeat, the rest is software based (and it doesn't matter if it's an Apple Watch or not).

Basically, praising the Apple Watch for doing something any device with HR hardware seems odd. Is there something I'm missing?

Graphene sieve turns seawater into drinking water    

April 3, 2017

Graphene-oxide membranes have attracted considerable attention as promising candidates for new filtration technologies. Now the much sought-after development of making membranes capable of sieving common salts has been achieved.

New research demonstrates the real-world potential of providing clean drinking water for millions of people who struggle to access adequate clean water sources.

The new findings from a group of scientists at The University of Manchester were published today in the journal Nature Nanotechnology. Previously graphene-oxide membranes have shown exciting potential for gas separation and water filtration.

Graphene-oxide membranes developed at the National Graphene Institute have already demonstrated the potential of filtering out small nanoparticles, organic molecules, and even large salts. Until now, however, they couldn't be used for sieving common salts used in desalination technologies, which require even smaller sieves.

Previous research at The University of Manchester found that if immersed in water, graphene-oxide membranes become slightly swollen and smaller salts flow through the membrane along with water, but larger ions or molecules are blocked.

The Manchester-based group have now further developed these graphene membranes and found a strategy to avoid the swelling of the membrane when exposed to water. The pore size in the membrane can be precisely controlled which can sieve common salts out of salty water and make it safe to drink.

As the effects of climate change continue to reduce modern city's water supplies, wealthy modern countries are also investing in desalination technologies. Following the severe floods in California major wealthy cities are also looking increasingly to alternative water solutions.

When the common salts are dissolved in water, they always form a 'shell' of water molecules around the salts molecules. This allows the tiny capillaries of the graphene-oxide membranes to block the salt from flowing along with the water. Water molecules are able to pass through the membrane barrier and flow anomalously fast which is ideal for application of these membranes for desalination.

Professor Rahul Nair, at The University of Manchester said: "Realisation of scalable membranes with uniform pore size down to atomic scale is a significant step forward and will open new possibilities for improving the efficiency of desalination technology.

"This is the first clear-cut experiment in this regime. We also demonstrate that there are realistic possibilities to scale up the described approach and mass produce graphene-based membranes with required sieve sizes."

Mr. Jijo Abraham and Dr. Vasu Siddeswara Kalangi were the joint-lead authors on the research paper: "The developed membranes are not only useful for desalination, but the atomic scale tunability of the pore size also opens new opportunity to fabricate membranes with on-demand filtration capable of filtering out ions according to their sizes." said Mr. Abraham.

By 2025 the UN expects that 14% of the world's population will encounter water scarcity. This technology has the potential to revolutionise water filtration across the world, in particular in countries which cannot afford large scale desalination plants.

It is hoped that graphene-oxide membrane systems can be built on smaller scales making this technology accessible to countries which do not have the financial infrastructure to fund large plants without compromising the yield of fresh water produced.

Agelbert NOTE:
PLEASE, spare me the, "but, but, you need fossil fuels to make graphene" argument. What you NEED is ENERGY. And there are MILLIONS of places on planet earth that you can HARVEST that (RENEWABLE) energy for an on location graphene factory that does not use ANY fossil fuels, EVER!

How big is a petabyte, exabyte or yottabyte? What’s the biggest byte for that matter? ???


Tibi Puiu March 17, 2017

SNIPPET:

In less than ten years flash card storage has increased 1,000 fold. Credit: Computer World.

Thirty years ago, back in 1983, the biggest hard drives stored about 10MB of data. That’s barely enough to store two or three .mp3 tracks. Now, a typical notebook has one terabyte of storage or nearly 100,000 times more but even this is figure is laughable when you consider how much data we’re generating. According to IBM, every day we’re creating 2.5 quintillion bytes of data and 90% of today’s digital data was created in the last two years.

Even those who are computer savvy still look at data at the gigabyte or terabyte scale but it’s clear we’re moving well past this point. It can get confusing and dizzy so let’s take a brief overview of how we quantify data and put some context on some of the more obscure units of digital information like the petabyte or yottabyte.

Partial Cures in Later Medieval Canonization Processes

September 13, 2016 By Medievalists.net


Heavenly Healing or Failure of Faith?    ???  Partial Cures in Later Medieval Canonization Processes

By Jenni Kuuliala

Introduction: For the past decades, canonization processes and miracle collections have provided a treasure trove for the historians of everyday life. Using them as source material, topics such as family life, childhood, and gender roles have been covered by many scholars, in addition to the study of the veneration of saints and the canonization process itself. Healing miracles, with their basis in the Bible, were the fundamental type of miracle performed by saints.

For medieval people, the miracles performed by Christ provided the models for subsequent miracles, which continued to be conducted after his life on earth. A high proportion of recorded miracles cured blindness, deafness, speech disorders, and various conditions impairing a person’s mobility. Therefore, they also provide a very unique source type for the study of medieval illness and health, as well as dis/ability.

Although many of the healing miracles included in later medieval canonization records, as well as in other types of miracle collections, are sudden, often even showy cures, a large proportion of the recoveries of particularly physical impairments and long-term illnesses were gradual.

Additionally, hagiographic sources include a group of miracles that were somehow partial. By ‘partial cure’, I mean healing miracles, after which some milder symptoms of the previous illness or impairment remained. The term is a modern one; although the sources record the possible ‘incompleteness’ of the cure, there is variation in the labelling and phrasing of them. Cures that can be defined as partial were, in any case, scrutinized relatively rarely in the canonization hearings.

Those scholars who have paid attention to their existence have explained this lack of coverage by interpreting them as failed miracles, or uninteresting to the commissioners. For example, Maria Wittmer-Butsch and Constanze Rendtel write that partial cures were most often rejected because they were considered rather as healings, not miracles, and thus no longer interesting for the process, and Stanko Andrić places partial cures in the category of failed, or ‘not-quite-successful’ miracles.

Lightweight, wearable tech efficiently converts body heat to electricity

September 12, 2016 by Matt Shipman

 
NC State University researchers have developed a new design for harvesting body heat and converting it into electricity for use in wearable electronics. The experimental prototypes are lightweight, conform to the shape of the body, and can generate far more electricity than previous lightweight heat harvesting technologies.

Researchers at North Carolina State University have developed a new design for harvesting body heat and converting it into electricity for use in wearable electronics. The experimental prototypes are lightweight, conform to the shape of the body, and can generate far more electricity than previous lightweight heat harvesting technologies.


The researchers also identified the optimal site on the body for heat harvesting.

"Wearable thermoelectric generators (TEGs) generate electricity by making use of the temperature differential between your body and the ambient air," says Daryoosh Vashaee, an associate professor of electrical and computer engineering at NC State and corresponding author of a paper on the work. "Previous approaches either made use of heat sinks—which are heavy, stiff and bulky—or were able to generate only one microwatt or less of power per centimeter squared (μW/cm2). Our technology generates up to 20 μW/cm2 and doesn't use a heat sink, making it lighter and much more comfortable."

The new design begins with a layer of thermally conductive material that rests on the skin and spreads out the heat. The conductive material is topped with a polymer layer that prevents the heat from dissipating through to the outside air. This forces the body heat to pass through a centrally-located TEG that is one cm2. Heat that is not converted into electricity passes through the TEG into an outer layer of thermally conductive material, which rapidly dissipates the heat. The entire system is thin—only 2 millimeters—and flexible.

"In this prototype, the TEG is only one centimeter squared, but we can easily make it larger, depending on a device's power needs," says Vashaee, who worked on the project as part of the National Science Foundation's Nanosystems Engineering Research Center for Advanced Self-Powered Systems of Integrated Sensors and Technologies (ASSIST) at NC State.

The researchers also found that the upper arm was the optimal location for heat harvesting. While the skin temperature is higher around the wrist, the irregular contour of the wrist limited the surface area of contact between the TEG band and the skin. Meanwhile, wearing the band on the chest limited air flow—limiting heat dissipation—since the chest is normally covered by a shirt.

In addition, the researchers incorporated the TEG into T-shirts. The researchers found that the T-shirt TEGs were still capable of generating 6 μW/cm2 - or as much as 16 μW/cm2 if a person is running.

"T-shirt TEGs are certainly viable for powering wearable technologies, but they're just not as efficient as the upper arm bands," Vashaee says.

"The goal of ASSIST is to make wearable technologies that can be used for long-term health monitoring, such as devices that track heart health or monitor physical and environmental variables to predict and prevent asthma attacks," he says.

"To do that, we want to make devices that don't rely on batteries. And we think this design and prototype moves us much closer to making that a reality."

The paper, "Wearable thermoelectric generators for human body heat harvesting," is published in the journal Applied Energy.
