Note to the telecom industry: Beware of false models — Tech News and Analysis
"At the World Radiocommunication Conference in 2015, one of the key debates will be whether to allocate more spectrum to wireless services. Yet, the data that informs this debate is deeply flawed, according to Tim Farrar, and overestimates the demand by as much as 1200 times."

How America's Soldiers Fight for the Spectrum on the Battlefield | Threat Level |
"It is well known that America’s military dominates both the air and the sea. What’s less celebrated is that the US has also dominated the spectrum, a feat that is just as critical to the success of operations. Communications, navigation, battlefield logistics, precision munitions—all of these depend on complete and unfettered access to the spectrum, territory that must be vigilantly defended from enemy combatants. " "Yet despite the importance of this crucial resource, America’s grip on the spectrum has never been more tenuous." "The American military is scrambling to develop new tools and techniques that will help it preserve its electromagnetic edge. But that edge continues to shrink by the day, and very soon our inability to completely control the spectrum might result in a different kind of war."

In the realm of Big Data ... | Bryant | First Monday - Feb 2014
Abstract In 2008, Chris Anderson (2008), at that time the Editor–in–Chief of Wired, proposed that in the age of the petabyte, there was no longer any need for the scientific method, nor for models or theories.... In what follows we focus initially on the term and the phenomenon, but our main objective is to argue that it is critical that there is general understanding of the emerging discipline. In particular we aim to justify the assertion that in the age of Big Data the ability to be able to develop abstractions and concepts is at least as important as it was previously; perhaps even more so.

Bose QuietComfort 20i Review - Watch CNET's Video Review
"The good: The Bose QuietComfort 20 and 20i are compact in-ear headphones that sound good, are very comfortable to wear, and offer surprisingly impressive noise cancellation. The noise cancellation is powered by an integrated rechargeable lithium battery that delivers up to 16 hours of battery life. The bad: Expensive; they don't sound as good as many competing in-ear headphones in this price range; rechargeable battery isn't replaceable. The bottom line: Despite some downsides, including a high price, the Bose QuietComfort 20 offers the best noise-canceling in an in-ear headphone and should tempt frequent travelers looking for a more compact alternative to a full-size NC headphone, such as the Bose QuietComfort 15."

Wireless Demand Projections – Elasticity of the Top-1% Percent Users | Media & Telecom: Valuation & Financial Consulting
Turns out that U.S. wireless traffic growth projections are being scaled back. Armand Musey thinks it’s due to Wi-Fi offload, and demand elasticity (i.e. if you force people to pay, they use less) The second factor was driven by the phasing out of unlimited data plans. But curiously, Musey reckons that carriers appear to be returning to unlimited data plans, so growth will pick up again. Presumably (and I guess not surprisingly) carriers will use Econ 101 to scale their customers’ data demand to the spectrum supply they’ve been able to extract from the FCC.

Debunking the Myth of the 10,000-Hours Rule: What It Actually Takes to Reach Genius-Level Excellence | Brain Pickings
"The secret to continued improvement, it turns out, isn’t the amount of time invested but the quality of that time... Instead, the factor Ericsson and other psychologists have identified as the main predictor of success is deliberate practice — persistent training to which you give your full concentration rather than just your time, often guided by a skilled expert, coach, or mentor. It’s a qualitative difference in how you pay attention, not a quantitative measure of clocking in the hours." "Goleman identifies a second necessary element: a feedback loop that allows you to spot errors as they occur and correct them, much like ballet dancers use mirrors during practice" "Additionally, the optimal kind of attention requires top-down focus." Quoting Goleman: "Ericsson finds world-class champions — whether weight-lifters, pianists, or a dog-sled team — tend to limit arduous practice to about four hours a day. "

Someone's Been Siphoning Data Through a Huge Security Hole in the Internet | Threat Level | Dec 2013
Quotes: Earlier this year, researchers say, someone mysteriously hijacked internet traffic headed to government agencies, corporate offices and other recipients in the U.S. and elsewhere and redirected it to Belarus and Iceland, before sending it on its way to its legitimate destinations. They did so repeatedly over several months. BGP eavesdropping has long been a known weakness, but no one is known to have intentionally exploited it like this until now. The technique doesn’t attack a bug or flaw in BGP, but simply takes advantage of the fact that BGP’s architecture is based on trust. To intercept data, anyone with a BGP router or control of a BGP router could send out an announcement for a range of IP addresses he wished to target that was narrower than the chunk advertised by other network routers. The announcement would take just minutes to propagate worldwide and, just like that, data that should have headed to those networks would begin arriving to the eavesdropper’s router in

Right Attitude - by Ajaan Suwat Suvaco, translated from the Thai by Thanissaro Bhikkhu
"Don't let yourself get bored or tired of the meditation. How do you develop a sense of ease? Through your conviction in what you're doing. No matter what the job, if you can do it with a sense of conviction, a sense of respect for your work, you can keep at it continuously. Even if the sun is beating down and you're all tired and worn out, you can keep on doing it. If you do it with a sense of desire (chanda) for the results, a sense of persistence (viriya), intentness (citta), and circumspection (vimansa), you can keep on doing it without getting tired. When you do your work with this attitude, you can keep at it always."

Séralini Threatens Lawsuit In Wake Of Retraction Of Infamous GMO Cancer Rat Study - Forbes
As the Genetic Literacy Project reports, the GMO wars are escalateing after the discrediting of a central pillar of the anti-crop biotechnology movement and the stumbling by a prominent science journal. Gilles-Éric Séralini, author of the controversial rat study that claimed to show that genetically modified corn could lead to a high incidence of cancer, says he is contemplating suing the journal that published the study if it goes through with its stated plan to retract it. In a stunning development, the editor of the Food and Chemical Toxicology, A. Wallace Hayes, sent the French scientist a letter dated November 19 saying that the paper will be withdrawn if Séralini does not agree to do it voluntarily. In either case, evidence of the discredited paper will be expunged from the journal’s database."

Science through Buddhist Eyes - The New Atlantis
Consciously and unconsciously, a new, modernized Buddhism began to take shape, one adapted to and by Western ways of thought. A trend called “Buddhist modernism” arose, aimed at reinterpreting Buddhism as a system of thought rather than a religion. Early leaders of this movement embraced mainly those elements of Buddhism that seemed to address the Western problems they were after, while rejecting elements that could not be made consonant with cherished notions like individualism and progressivism. But while some of the aims, methods, and attitudes of Buddhism and modern science may appear similar, at the most fundamental level they are quite different. A Buddhist meditation teaching goes: “small doubt, small awakening; big doubt, big awakening; no doubt, no awakening.” Buddhism is meant eventually to dismantle itself. So we might better advance the discussion not by highlighting where Buddhism and science see eye-to-eye, but precisely where they do not, perhaps forcing each to c

Opinion analysis – “Pandora’s box” stays closed : SCOTUSblog May 2013
Monday’s opinion in City of Arlington v. FCC is surely destined for administrative law textbooks. One reason is that the Court at last resolved a longstanding dispute in the field: whether agencies are eligible for deference under Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc. when interpreting the scope of their own so-called “jurisdiction.” The answer is yes; as Justice Scalia’s majority opinion explains, the distinction between jurisdictional questions and non-jurisdictional interpretations is “a mirage.” . . . Oral argument focused significantly on the puzzle of cordoning off “jurisdictional” questions from other questions of agency interpretation.

Scientists say this is the "first observation of mechanical gearing in a biological structure.""

What Emerging Knowledge Economy? | Robert D. Atkinson, Ph.D. Aug 2013
"It's not uncommon for many college education and STEM advocates to claim that the fastest growing occupations over the next decade will require a college education and/or STEM skills. In this view, the economy is shedding low skill jobs (either from automation or trade) and America is specializing in high-wage, knowledge-based jobs that require a college degree. But if we are to have a really objective and productive debate about education policy, it's important to base it on reality not wishful thinking. And the reality is that when measured in terms of absolute growth (not percentage change) in job openings between 2010 and 2020, none of the top fastest growing occupations even require a bachelor's degree, and six of them don't even require a high school degree. And collectively these jobs make up more than 20 percent of the expected job openings by 2020 and pay median wages of just $26,150 per year. This by the way, goes a long way in explaining stagnant U.S. wages. "

Sampling in Statistical Inference - statistic vs. parameter
Quote: The use of randomization in sampling allows for the analysis of results using the methods of statistical inference. Statistical inference is based on the laws of probability, and allows analysts to infer conclusions about a given population based on results observed through random sampling. Two of the key terms in statistical inference are parameter and statistic: A parameter is a number describing a population, such as a percentage or proportion. A statistic is a number which may be computed from the data observed in a random sample without requiring the use of any unknown parameters, such as a sample mean.

End of Moore's Law: It's not just about physics | Business Tech - CNET News
Bob Colwell, DARPA: "[It takes] huge amounts to build the fab plants, and yet pay for the design teams to design new chips. Intel makes these investments, which are in the [billions of dollars], because they expect to reap way more [billions of dollars] in profits in the following years. But if there is doubt that those profits will arrive, and possibly if they just doubt they can come up with the necessary silicon improvements, they may not want to make the investment at all. Should a major player like Intel make such a call, that would effectively end Moore's Law all by itself, because then the various companies that make the super expensive tools for chip production will themselves not make the investments needed to keep Moore's Law alive."

"A secretive U.S. Drug Enforcement Administration unit is funneling information from intelligence intercepts, wiretaps, informants and a massive database of telephone records to authorities across the nation to help them launch criminal investigations of Americans. Although these cases rarely involve national security issues, documents reviewed by Reuters show that law enforcement agents have been directed to conceal how such investigations truly begin - not only from defense lawyers but also sometimes from prosecutors and judges. The undated documents show that federal agents are trained to "recreate" the investigative trail to effectively cover up where the information originated, a practice that some experts say violates a defendant's Constitutional right to a fair trial. If defendants don't know how an investigation began, they cannot know to ask to review potential sources of exculpatory evidence - information that could reveal entrapment, mistakes or biased witnesses."

Now That It's in the Broadband Game, Google Flip-Flops on Network Neutrality | Threat Level | Jul 2012
"In a dramatic about-face on a key internet issue yesterday, Google told the FCC that the network neutrality rules Google once championed don’t give citizens the right to run servers on their home broadband connections, and that the Google Fiber network is perfectly within its rights to prohibit customers from attaching the legal devices of their choice to its network. At issue is Google Fiber’s Terms of Service, which contains a broad prohibition against customers attaching “servers” to its ultrafast 1 Gbps network in Kansas City. Google wants to ban the use of servers because it plans to offer a business class offering in the future. A potential customer, Douglas McClendon, filed a complaint against the policy in 2012 with the FCC, which eventually ordered Google to explain its reasoning by July 29. In its response, Google defended its sweeping ban by citing the very ISPs it opposed through the years-long fight for rules that require broadband providers to treat all packets equ...

Ann Arbor and the future of V2V/V2I, part II | Telematics Update
"[With the possibility of NHTSA ruling at the end of the year], the ITS community should have every reason to be hopeful. The timing [of the FCC NPRM] is potentially disastrous for the ITS community. That’s because the current DSRC test beds, including the Ann Arbor Safety Pilot, were never designed to assess potential complications from signal interference that may accompany an open 5.9 GHz band. “The FCC’s decision suggests a high degree of skepticism at this point at the FCC,” says Roger Lanctot of Strategy Analytics. One of the main reasons is that V2V and V2I applications can now be achieved with technologies other than DSRC. The LTE Advanced standard is beginning to add proximity sensing, a Wi-Fi-related functionality that could be used for V2V communications."

The trial will run through fall 2013, and results will be sent to the National Highway Traffic Safety Administration (NHTSA) as it considers whether to approve national V2V and V2I mandates for DSRC implementation." "Since the Federal Communications Commission (FCC) granted vehicle makers exclusive use of the 5.9 GHz band in 1999, the promise of DSRC as a foundation for V2V and V2I systems has remained both tantalizing and elusive in North America. Now, with new technologies nipping at DSRC’s heels and no nationwide implementation strategy in place, time may be running out for the ITS community to prove the technology’s viability."

It appears that shared spectrum use will, at least for now, continue to be largely limited to short-range private networks ... Another possibility is that shared spectrum will simply be used by traditional wireless operators ...

description of modulation, and why I and Q are useful when thinking about phase "I/Q data is merely a translation of amplitude and phase data from a polar coordinate system to a cartesian (X,Y) coordinate system" " What this essentially means is that we can control the amplitude, frequency, and phase of a modulating RF carrier sine wave by simply manipulating the amplitudes of separate I and Q input signals! With this method, we no longer have to directly vary the phase of an RF carrier sine wave. We can achieve the same effect by manipulating the amplitudes of input I and Q signals."

Diederik Stapel’s Audacious Academic Fraud -
"Diederik Stapel, a Dutch social psychologist, perpetrated an audacious academic fraud by making up studies that told the world what it wanted to hear about human nature." "But the scientific misconduct that has come to light in recent years suggests at the very least that the number of bad actors in science isn’t as insignificant as many would like to believe. In his early years of research — when he supposedly collected real experimental data — Stapel wrote papers laying out complicated and messy relationships between multiple variables. He soon realized that journal editors preferred simplicity. “They are actually telling you: ‘Leave out this stuff. Make it simpler,’ ” Stapel told me. Before long, he was striving to write elegant articles."
