The Surprising Boost You Get From Strangers - WSJ By Elizabeth Bernstein, May 2019
Via WSJ 19/20 Jun 2019

"Sometimes a stranger—not a friend or a loved one—can significantly improve our day. A pleasant encounter with someone we don’t know, even a nonverbal one, can soothe us when no one else is around. It may get us out of our own head—a proven mood booster—and help broaden our perspective. "

Ten Ways to Connect With Strangers

Be brave.
Chat up someone you see regularly
Ask about the other person. Everyone loves to talk about themselves.
Bond during a challenging experience
Ask for help.
Focus on what you have in common.
Mutual disclosure helps.
Use humor.
Make sure the interaction is equal.
Do it again.

In Search of Lost Time on YouTube - The New Atlantis, Laurence Scott, Summer 2019
"But while there are few things more clearly of-the-moment than our biggest video-sharing site, YouTube is also the closest thing we have invented to a time machine: Its channels open new routes back to the past. Over these years I’ve come to understand that my YouTube, what I make of it, is one of the most melancholy places I’ve ever visited"

"The French theorist Roland Barthes was sensitive to both the melancholy and the spectrality of images from the past. His concept of “the punctum,” which he formulated in his meditation on photography, Camera Lucida (1980), predicts some of the angst of inhabiting YouTube’s emotional landscape, its world of resurrected moments. The punctum is a detail in a photographic image that pierces the viewer’s imagination. For Barthes, it is “that accident which pricks me (but also bruises me, is poignant to me).” The punctum is never part of an image’s intended meaning, never a planned, conscious detail but rather an accidental, tiny storehouse of emotion. Watching old YouTube videos originating from my childhood years is guaranteed to leave me feeling like a pincushion. The puncta are everywhere."

"Much of my YouTube nostalgia is explicitly, tenaciously sought. With eyes wide open, I’ve gone in search of a specific scene from the 1980s cartoon Ulysses 31, a sci-fi retelling of Homer’s Odyssey."

' “What are you doing here?” carries with it an air of trespass that can accompany any journey into the YouTube Time Machine. The controversial Article 13 of the new digital copyright law, just passed in the European Parliament, seeks to make YouTube and other platforms responsible for policing the illegal use of copyrighted content. '

"The digital, unbloody ease with which YouTube revives the past, so much more nimbly than its DVD and VCR predecessors, invites us to become re-watchers of the same content. Indeed, quick repetition is a main feature of our new digital aesthetics. Whereas we use GIFs — those twitchy, looping clips — as public illustrations of our feelings or responses to events, an oft-repeated YouTube video is the GIF’s private counterpart. Re-watching familiar videos can be a kind of secular prayer. There is comfort in the repetition, and the videos to which we give this repeated attention can feel deeply personal."

"The way cameras capture sunlight — how sharp or powdery or white or golden — or the subtle changes in tone that microphones give to voices, are historically specific."

"For Freud, melancholia and mourning are both connected to a loss, but differ in how the loss is perceived. While a mourner is vividly aware of why he despairs, the source of a melancholic’s lamentation can be harder to identify."

Definition and Examples of Narratives in Writing - ThoughtCo
The definition of narrative<> is a piece of writing that tells a story, and it is one of four classical rhetorical modes or ways that writers use to present information. The others include an exposition, which explains and analyzes an idea or set of ideas; an argument, which attempts to persuade the reader to a particular point of view; and a description, a written form of a visual experience.

(81) Building 15-Foot-Tall Pianos - YouTube May 2019
David Klavins is a pianist who, for years, could not find pianos that made the sounds he imagined in his head. So he began building pianos to his own specifications in a workshop in Vác, Hungary, and they are truly unique creations. To wit: Klavins’ vertical concert grand stands over 15-feet tall, and he actually has to climb a ladder to play it, which he does, beautifully, just for us.

There's a dark side to self-control. Here's why you should loosen up | New Scientist Nov 2018
"Willpower is the secret of success – or so we've been told. But too much can be bad for the body and mind. The trick is to know when to give in to temptation"

"Much of our current understanding of self-control stems from the work of psychologist Walter Mischel "

"What’s more, the greater obedience associated with high self-control may be damaging for oneself as well as others. People with high self-control report feeling less satisfied with their partners and colleagues, believing that others take advantage of their dependability."

"She found that small cues indicating high self-control (whether someone flosses their teeth, for instance) prompted volunteers to allocate them more work, while also underestimating the effort they would need to put in to complete the work. The assumption, it seemed, was that someone with high self-control could simply “get on with it”. Koval says she has witnessed many friends and colleagues who have been taken advantage of in this way. "

"And it gets worse. In the long run, high self-control can be a source of regret. ... Rather than feeling pride in their achievements, most wished that they had exercised less self-control, not more."

"Perhaps the most troubling finding, however, comes from a survey of nearly 700 African American families from poor neighbourhoods. In line with much of the previous research, teachers’ assessments of children’s self-control predicted many later outcomes: those scoring highly were more likely to enter college, for instance. Yet they also had high blood pressure and showed elevated levels of hormones commonly associated with stress."

" At the very least, programmes designed to boost self-control should offer greater support to help children cope with those additional stresses. But Uziel is also keen on using so-called nudge techniques to improve behaviour without the need for self-control. "

"As Uziel points out, people with high self-control may doggedly pursue a goal even once it has stopped being personally meaningful. You might also make more effort to deliberately leave empty windows in your diary that allow greater spontaneity and indulgence (see “A lazy path to self-control”)."

How Jury Duty Gives You the Power to Erase Bad Laws | The Daily Bell
Via Prison Legal News, Jan 2019

"As a juror, you do NOT have to deliver a guilty verdict, even if you are 100% sure he committed the “crime.” Instead, you can disagree that it should be criminal at all, and say not guilty.

Unfortunately, defense attorneys are often not allowed to argue in court for jury nullification. The judge can force them to only argue the facts of the case. They usually cannot suggest that the jury find the defendant not guilty because the law is unjust."

Turning the Satellite Business Model Upside-Down - NSR Gagan Agrawal, Nov 2017
The traditional satcom industry can be argued to be entering its third transition phase, after the FSS video boom until 2010 and the HTS influenced pricing decline more recently. With languishing growth in 2018, alongside declining EBITDA margins and backlog, the operator industry remains uncertain on video, while debating on the merits of going fully downstream in the long term. Several factors such as high regional competition, video demand absorption through higher compression, supply-demand mismatch impact on pricing, pressure from OTT, and commoditization of capacity have driven the market to a stagnation point. However, no trend is bigger than the continuous manufacturing innovation to pack more Mbps per unit of million dollars cost. By pushing CAPEX per Gbps to ever more efficient levels, operators are able to undercut competitors on lease pricing, forcing many to sell at or below break-even profit margins, creating a zero-sum effect overall.

Large Majorities Dislike Political Correctness - The Atlantic Oct 2018
"On social media, the country seems to divide into two neat camps: Call them the woke and the resentful. "

"Reality is nothing like this. As scholars Stephen Hawkins, Daniel Yudkin, Miriam Juan-Torres, and Tim Dixon argue in a report published Wednesday, “Hidden Tribes: A Study of America’s Polarized Landscape,” most Americans don’t fit into either of these camps. They also share more common ground than the daily fights on social media might suggest—including a general aversion to PC culture."

"If you look at what Americans have to say on issues such as immigration, the extent of white privilege, and the prevalence of sexual harassment, the authors argue, seven distinct clusters emerge: progressive activists, traditional liberals, passive liberals, the politically disengaged, moderates, traditional conservatives, and devoted conservatives."

"According to the report, 25 percent of Americans are traditional or devoted conservatives, and their views are far outside the American mainstream. Some 8 percent of Americans are progressive activists, and their views are even less typical. By contrast, the two-thirds of Americans who don’t belong to either extreme constitute an “exhausted majority.” Their members “share a sense of fatigue with our polarized national conversation, a willingness to be flexible in their political viewpoints, and a lack of voice in the national conversation.”"

"Three quarters of African Americans oppose political correctness."

"If age and race do not predict support for political correctness, what does? Income and education. ... Political tribe—as defined by the authors—is an even better predictor of views on political correctness."

"The gap between the progressive perception and the reality of public views on this issue could do damage to the institutions that the woke elite collectively run. "

" As one 57- year-old woman in Mississippi fretted:

The way you have to term everything just right. And if you don’t term it right you discriminate them. It’s like everybody is going to be in the know of what people call themselves now and some of us just don’t know. But if you don’t know then there is something seriously wrong with you."

Reading in the era of digitisation: An introduction to the special issue | Kovač | First Monday Sep 2018
"Digital materials can be adapted to each individual’s skill level, enabling flexible learning processes to accommodate the particular needs and developments of each reader. At the same time, empirical research indicates that the affordances of screens may also foster less advantageous reading developments, habits and mind sets.

"This warrants balancing the discourse on possibilities and advantages of digital technologies. To this purpose ‘Evolution of Reading in the Age of Digitisation’ (E-READ) — a research initiative funded by COST (European Cooperation in Science & Technology) as Action IS1404 — has brought together almost 200 scholars and scientists of reading, publishing, and literacy from across Europe. Starting from the assumption that the introduction of digital technologies for reading is not neutral regarding cognition and comprehension, the members of the network joined in an effort to research how readers, and particularly children and young adults, comprehend or remember written text when using print versus digital materials.

"The main findings can be summarised in the following manner:

General comprehension when reading long-form text on a digital screen tends to be either about the same as or inferior to doing the same reading in print;

More demanding tasks (e.g., requiring greater depth of understanding or reproduction of detail or when longer texts are used) suffer more than leisure tasks (e.g., narrative reading);

Readers are more likely to be overconfident about their comprehension abilities when reading digitally than when reading print, in particular under time pressure;

Contrary to expectations about the behaviour of ‘digital natives’, screen inferiority effects have been increasing rather than decreasing over time, regardless of the age group and regardless of prior experience with digital environments;

Digital text offers unsurpassed opportunities to tailor text presentation to an individual’s needs, which has been found to support struggling readers to develop adequate reading skills;

Equivalence between the paper and screen mediums — and even an advantage of digital environments — can be achieved, provided conscious engagement in in-depth processing (e.g., writing keywords that summarize the text) is actively promoted.

Uncannily real: volumetric video changes everything | New Scientist Dec 2017
Wonderful essay by Simon Ings - neat twist in the tail, I love the open to close:

"<open> OUTSIDE Dimension Studios in Wimbledon, south London, is one of those tiny wood-framed snack bars that served commercial travellers in the days before motorways. The hut is guarded by old shop dummies dressed in fishnet tights and pirate hats. If the UK made its own dilapidated version of Westworld, the cyborg rebellion would surely begin here.
<close> Jelley walks me back to the main road. Neither of us says a word. He knows what he has. He knows what he has done. Outside the snack shack, three shop dummies in pirate gear wobble in the wind."

"Truly immersive media will be achieved not through magic bullets, but through thugging – the application of ever more computer power, and the ever-faster processing of more and more data points. Impressive, but where’s the breakthrough?"

"The cameras shoot between 30 and 60 times a second. “We have a directional map of the configuration of those cameras, and we overlay that with a depth map that we’ve captured from the IR cameras. Then we can do all the pixel interpolation.” This is a big step up from mocap. Volumetric video captures real-time depth information from surfaces themselves: there are no fluorescent sticky dots or sliced-through ping-pong balls attached to actors here."

Niche construction: the forgotten force of evolution | New Scientist, Nov 2003
By Kevin Laland and John Odling-Smee

"Our studies have convinced us that niche construction should be recognised as a significant cause of evolution, on a par with natural selection."

"Put another way, the only relevant evolutionary feedback from extended phenotypes is to the genes that express them. So when beavers build dams, they ensure the propagation of “genes for” dam building, but that is all. Yet by constructing their own niche, beavers radically alter their environment in many ways. "

"Across the globe, earthworms have dramatically changed the structure and chemistry of soil by burrowing, dragging plant material into the soil, mixing it up with inorganic material such as sand, and mulching the lot by ingesting and excreting it as worm casts. The scale of these earthworks is vast. What’s more, because earthworm activities result in cumulative improvements in soil over long periods of time, it follows that today’s earthworms inhabit environments that have been radically altered by their ancestors. In other words, some extended phenotypes can be inherited. "

New generation of non-geostationary constellations poses challenges for WRC-19 | PolicyTracker: the spectrum management newsletter
"Article 22.2 of the Radio Regulations, the ITU document that manages international spectrum use, states that geostationary orbit (GSO) satellites cannot receive interference from NGSO satellites in fixed-satellite service (FSS) bands. However, the regulations do not yet include any rules on how this is to be achieved above 30 GHz.

To address this, agenda item 1.6 of WRC-19 considers the regulatory framework for NGSO satellites to use the fixed-satellite service at 37.5–39.5 GHz (space-to-Earth), 47.2–50.2 GHz (Earth-to-space) and 50.4–51.4 GHz (Earth-to-space).

In addition to preventing interference to GSO satellites, the rules also need to find a way for NGSO satellites to avoid interference to each other, to passive earth exploration satellite services at 36-37 GHz and 50.2-50.4 GHz and to radio astronomy services at 42.5-43.5 GHz, 48.94-49.04 GHz and 51.4-54.25 GHz."

"... WP 4A had identified a way to calculate unavailability: the convolution methodology. This is meant to protect GSO satellites without imposing onerous and spectrally inefficient equivalent power flux-density (EPFD) limits on NGSO systems.

It works by calculating the single entry increase in unavailability to a reference GSO link, compared to a maximum stipulated in the Radio Regulations. Administrations then determine the overall increase in link unavailability so that aggregate interference will not degrade the GSO satellites’ availability by more than 10 per cent."

US IWG-3: "Alexander Epshteyn, an engineer at Boeing, drafted a paper for the group’s meeting in late March that proposed solutions to protect GSO networks based on the convolution methodology."

[pdf] ECC Report 249 - Unwanted emissions of common radio systems: measurements and use in sharing/compatibility studies - Apr 2016
"The scope of this report is:

 To compare the measured characteristics of a limited number of equipment samples with the existing regulatory limits in order:

 To explore the current definitions of the limits used for the OoB and spurious domains given in ITU-R Recommendations and ETSI standards

 To compare the "safety-net" worst case characteristics of OoB emissions in Rec. ITU-R SM.1541 [1] and the measurements of the equipment samples

 To compare spurious domains emissions in ERC/REC 74-01 [2] Rec. ITU-R SM.329 Category B and the measurements of the equipment samples

 To characterise the unwanted emissions of various digital modulation technologies of broadband communication systems. It considers the boundary between the out-of-band (OoB) and spurious domains as well as the levels of unwanted emissions in a set of measurements on equipment samples.

 To develop possible concepts to better characterise the unwanted emissions of broadband systems using digital technology to enable a more efficient use of the radio spectrum in adjacent bands."

"It is observed that the measured emissions are typically lower than the limits in
recommendations and ETSI standards by a significant margin of several tens of dBs in the spurious domain,
except for the harmonic frequencies. This finding has an important implication for sharing and compatibility
studies which are typically based on the assumption that equipment would only just meet the limits set out in
standards. "

"Two questions are raised:

1 Should sharing/compatibility studies be based on typical performance of unwanted emissions rather than the limits?

2 Should those limits/levels in bands adjacent to the operating one (and boundary between the OoB and spurious domains) be redefined or be re-considered on a case-by-case basis to better reflect actual performance of equipment, and therefore allow for increased opportunities for sharing/compatibility and more efficient use of spectrum in future?"

"Regarding the out-of-band domain limits, the measurements have shown that the limits specified in ETSI standards are generally the relevant limits particularly tailored to the specific application; ITU-R SM.1541 [1] (containing only the "safety-net" limits which are mainly only based on services) consequently shows a large margin as expected."

"In response to increasing demand for satellite communications – and reflective of international cooperation to facilitate expanded access to satellite connectivity – harmful interference prevention regulations and measures are being discussed, developed and implemented worldwide. Building upon dialogue between the ITU and the international ICT community during WRC-12, which has been ongoing since, the Bureau is pleased to announce the holding of a one-day workshop in Geneva on 10 June 2013.

"The Geneva workshop will be an open event where participation of national administrations, the satellite communications industry, user community, other ICT stakeholders, as well as all those with an interest in the topic, is strongly encouraged.

"The workshop will provide ITU stakeholders with an opportunity:

= to learn about harmful interference situations affecting satellite systems,
= to review the ongoing regulatory and technical initiatives and strategies for solving the issue, and
= to share reports on practices and the impact those measures are having on ICT operational effectiveness and service."

Wokeness and Myth on Campus - The New Atlantis Jan 2018
"The problem lies in a failure to grasp the true nature of the students’ position. If we are going to understand that position, we will need to draw on intellectual sources quite other than those typically invoked. What is required of us is the study of myth — and not in any pejorative or dismissive sense, but in the sense of an ineradicable element of human consciousness."

Polish philosopher Leszek Kołakowski's "technological core is analytical, sequential, and empirical. Another way to put this is to say that what belongs to the technological core is what we find to hand: whatever occupies the lifeworld we share, and is therefore subject to our manipulation and control, and to debates about what it is and what might be done with it. To this core belong instrumental and discursive reason, including all the sciences and most forms of philosophy — everything that reckons with the possible uses of human power to shape ourselves and our environment. The technological core undergirds and produces the phenomena we typically refer to as technological.

The “mythical core” of civilization, by contrast, describes that aspect of our experience “not revealed by scientific questions and beliefs.” It encompasses the “nonempirical unconditioned reality” of our experience, that which is not amenable to confirmation or disconfirmation."

"... as Kołakowski contends, the technological core and the mythical core will always come into regular and profound conflict with each other: “The futility of this clash would not in the end be so burdensome were it not that both points of view, incapable of synthesis and eternally in conflict, are after all present in [every one] of us, although in varying degrees of vitality. They have to coexist and yet they cannot coexist.”"

Amid Evangelical decline, growing split between young Christians and church elders -, Nov 2017
"... there are signs that many of the same trends that decimated mainline Protestantism over the past few decades are now at work among evangelical denominations as well. According to a massive study by the Public Religion Research Institute (PRRI) released in September, the number of white evangelical Protestants fell from about 23 percent of the US population in 2006 to 17 percent in 2016."

"For Andrew Walker, the current “post-Christian” state of American culture has posed a serious challenge to the faithful. For a variety of reasons, fewer and fewer Americans now have a grasp of the fundamentals of orthodox, biblical teachings, ... he notes, too, the dramatic rise of the so-called “nones,” especially among the young, who may believe in God, but have begun to refuse to identify with a particular religious group."

"Perhaps more than anything else, conservative Christians ... have had to confront the shock of the country’s evolving sexual mores."

“They grew up in a nominal Christian culture, where it’s no longer of a cultural or social benefit to identify as a Christian,” he says. “To add to that is, there’s often not only no social prestige to gain, there’s also social prestige to lose, if you say you are a Christian in our society.”

Yet narratives of danger and decline also help to motivate the faithful, notes Glenn Bracey, professor of sociology at Villanova University in Pennsylvania. “White Evangelicals often describe themselves as culturally embattled, and that perspective often increases members’ commitment to their organizations and politics.”

"Yet precisely because of such efforts [to reassert the fundamentals of Christian orthodoxy and ratchet up their political efforts], younger conservative Christians like Chelsie Maynard have been conflicted about their religious identities, and many say they no longer want to be associated with the evangelical demographic."

"Some Evangelicals have called for another retreat from society... The Christian thinker Rod Dreher has proposed a “Benedict Option,” suggesting that Christians forgo politics and adopt a kind of monastic shield from society."

"For many Evangelicals, the Nashville Statement was simply an affirmation of Christianity’s historic moral teachings and a pastoral document to guide the faithful. But critics noted that the statement went beyond condemning homosexuality and transgender identity: It also condemned those who affirm them."

Daniel Kahneman: The riddle of experience vs. memory | TED Talk |
Via Linda Change

Three cognitive traps around "happiness":

1. Complexity: too many possible meanings, "happiness" not a useful word anymore, will have to give up use of the word

2. confusion between experience and memory: i.e. being happy in your life vs. being happy about/with your life

3. focusing illusion: we cant' think about anything related to well-being without distorting its importance

"The remembering self is a story-teller"

Colonoscopy example - important thing about a story is changes, significant moments, and (especially) how it ends (JP: raises hard questions about utilitarianism!)

"Time (duration) has very little impact on the story"

"WE don't choose between experiences, we choose between memories of experiences. ... We think of our future as anticipated memories"

Two selves (experiencing and remembering) --> two notions of happiness

"We really should not think of happiness as a substitute for well-being"

The Key Mental Habit of Simplicity : zen habits
So here’s what I’ve learned is the key mental habit of simplicity: noticing the mind’s tendency to want more, and don’t believe it.

The mind always wants more. And at the same time, it wants less — there’s a polarity in the mind that craves simplicity and craves more.

The process is simple:

= develop awareness of your mental habits over time
= see what their harmful effects might be
= stop believing the thoughts
= make a loving effort to change them
= and don’t expect perfection

I-Connect007 :: Article The Radio Frequency Spectrum + Machine Learning = a New Wave in Radio Technology
" there now is a need to apply ML to the invisible realm of radio frequency (RF) signals, according to program manager Paul Tilghman of DARPA’s Microsystems Technology Office. To further that cause, DARPA today announced its new Radio Frequency Machine Learning Systems (RFMLS) program."

“What I am imagining is the ability of an RF Machine Learning system to see and understand the composition of the radio frequency spectrum – the kinds of signals occupying it, differentiating those that are ‘important’ from the background, and identifying those that don’t follow the rules,” said Tilghman.

"stand up an RF forensics capability to identify unique and peculiar signals amongst the proverbial cocktail party of signals out there"

"In his 4th-century BC treatise on rhetoric, the ancient Greek philosopher Aristotle distinguished arguments rooted in facts and figures (which he called logos) from appeals that rely on the speaker’s credibility and expertise (ethos) and statements playing on an audience’s emotions (pathos). All three strands are readily discernible in public debate today. The successful campaign for the UK to vote to leave the European Union was arguably a triumph of pathos over logos; when Donald Trump punctuates his speeches with the refrain “believe me”, he is employing ethos, urging listeners to respect his authority."

“The growth of social media has radically awakened our individual expressive capacity,” says Carl Miller of the London-based think tank Demos. “But it hasn’t allowed us to compromise any better.” Reed agrees. “This is a deep structural problem. It’s really hard – even if you’re very motivated – to build up a coherent picture of the arguments pro and con on a particular debate.”

"Reed’s favourite source is the BBC radio show Moral Maze, in which panellists debate the ethics of an issue of the day. Its quasi-legal cut and thrust, laced with pathos and ethos, is just the thing from which to build a general framework for the essence of human argument. ... His team has since repeated the exercise many times, dissecting episodes of Moral Maze and other broadcast and print sources, plus some online forum postings, and turning them into a public databank of argument maps, accessible at "

Will Communications Theory Finally Make Itself Redundant? A View from the Academic Trenches | Petar Popovski - IEEE Communications Society
He starts with an old Balkan joke about a lawyer and a tree

He asserts that “there are clear signs that the communication engineering, and especially research in communication engineering, is losing its traction and gives way to other engineering disciplines, such as e.g. machine learning.”

He then suggests three “tracks that have the potential to drive a new and exciting research in communication theory over a longer period”

1. Communication under adversarial impact: “when dealing with adversarial impact instead of dealing only with physical limits, it is much more difficult, if at all possible, to reach a saturation point for research, since the adversary is doing his/her research as well”

2. Interaction among vertical services: “What are the fundamental communication-theoretic problems that arise from interaction among multiple vertical connections, each with different requirements? … In spectrum regulation, and especially for unlicensed spectrum, there is the tendency to make spectrum usage rules generic, as much as possible independent of the requirements of the vertical service. Net neutrality also ... Building a communication theory that addresses the fundamentals of interaction among multiple vertical services, has the potential to change the way we configure communication systems, as well as utilize and regulate the spectrum and communication services.”

3. Communication beyond dedicated electronic circuits: “communication theory leans towards a mathematical sub-discipline. The latter means that communication theory is not necessarily applied only to electronic circuits that are built for communication and has wider implications.”

Verizon and Charter: the Trump era heralds a wave of European-style cable–mobile consolidation - AnalysysMason Jan 207
"Seeing every Verizon move through the teleology of 5G misses the point; US mobile is shrinking and Verizon needs to spread its bets."

"In pursuing a mobile-first strategy, Verizon has progressively shrunk its wireline footprint. In the early part of last decade, the company was a proponent of FTTP, but found the capex burden intolerable, and of its 22% wireline coverage, only 15% has FiOS (FTTP) availability, with the rest on low-grade ADSL. Charter acquired the larger Time Warner Cable and the smaller Bright House Networks in 2015."

"Analysys Mason's view is that the USA is waking up to the same realities that hit Europe a few years ago: a mobile-first strategy no longer makes any 'industrial' sense, and the survival of mobile-only operators into the 5G era is in question. Market structure (with a geographical fragmentation of fixed but not mobile) has shielded the USA from this, as it has in other markets with a similar asymmetric structure such as Finland and Russia. While 5G-readiness is something to aspire to, the rationale for any merger is, from Verizon's point of view, much more immediate and banal: mobile revenue will come under increasing pressure; broadband/video has more growth potential than mobile; and fixed–wireless may not work."

"Analysys Mason forecasts rises in consumer wireline revenue and a decline in mobile revenue between now and 2021 in the USA."

"We believe that Verizon's interest in cable is at least in part motivated by the realisation that mmWave fixed–wireless (pre-standards 5G) is not the best way to address the great indoors."

Op-ed: I’m throwing in the towel on PGP, and I work in security | Ars Technica - Filipps Valsorda Dec 2016
“If you need to securely contact me... DM me asking for my Signal number.”
"If we meet in person and need to set up a secure channel, we will just exchange a secret passphrase to use with what's most appropriate: OTR, Pond, Ricochet."
"All in all, I should be the perfect user for PGP: competent, enthusiast, embedded in a similar community. But it just didn't work."
"A long-term key is as secure as the minimum common denominator of your security practices over its lifetime. It's the weak link."

[pdf] The Financial Modelers' Manifesto - by Emanuel Derman and Paul Wilmott
originally written by Emanuel Derman and Paul Wilmott in the wake of the 2008 financial crisis:

∼ I will remember that I didn’t make the world, and it doesn’t satisfy my equations.

∼ Though I will use models boldly to estimate value, I will not be overly impressed by mathematics.

∼ I will never sacrifice reality for elegance without explaining why I have done so.

∼ Nor will I give the people who use my model false comfort about its accuracy. Instead, I will make explicit its assumptions and oversights.

∼ I understand that my work may have enormous effects on society and the economy, many of them beyond my comprehension.
