Another puzzle video -- going meta on Dudeney's Beer Barrel Puzzle
First off, you'll notice that things look a bit different. A friend of mine who works in postproduction (welcome to LA) made up an opening title sequence for the series. The video still looks like something done quickly on the cheap, but hopefully we've gotten to the point where the amateurism is not distracting.
My main focus here and what I want to direct your attention to is the meta. The central idea which is basically taken from George Pólya is that mathematics instruction should be less concerned with individual problems and more concerned with teaching the process of problem solving.
Puzzles are a natural fit for this concept. Their value for explicitly introducing heuristics has been demonstrated by any number of smart people such as Pólya, Martin Gardner (particularly in the Aha! books) and Raymond Smullyan, but the approach has never gotten the traction it deserves, perhaps because it requires both mathematical sophistication and a sense of humor, two qualities sadly lacking in both in traditional education programs and in the reform movement.
With that objective in mind, take a look, let me know what you think, and, if you're so inclined, feel free to share this with anyone who might be interested.
I used this problem as a jumping off point to discuss trial and error methods. For the more mathematically inclined, Dudeney's original solution might be of more interest.
From sandwich-makers to sitcoms -- more tales of monopsony
Continuing our abuse of economic power thread from yesterday, Ken Levine (the writer/director/producer associated with about half the classic television shows you can think of) has an excellent post on the annual upfronts. For those of you not from LA, here's a primer from Wikipedia:
All of these new sources of competition continued to erode (losing a monopoly will do that), but they remained one of the dominant forces in the media landscape and thanks to deregulation and industry consolidation, companies like NBC/Universal/Comcast have unprecedented freedom to abuse market power.
We're thirty-plus years into an experiment in laissez-faire economics and certain conclusions are difficult to avoid.
1. Left unchecked, economic power tends to consolidate.
2. Once gained, that power is remarkably difficult to lose, even in the case of spectacularly incompetent management.
3. Inevitably, that power will be abused.
As a statistician, I know I'm always supposed to be calling for more data, but in this case, I think we have enough.
Levine's whole post is worth reading but given some of our recent discussions, this part seemed particularly relevant.
In the North American television industry, an upfront is a group of gatherings hosted at the start of important advertising sales periods by television network executives, attended by the press and major advertisers. It is so named because of its main purpose, to allow marketers to buy television commercial airtime "up front", or several months before the television season begins.
The first upfront presentation was made by ABC in 1962, in an attempt to find out how advertisers felt about the network's new shows.
In the United States, the major broadcast networks' upfronts occur in New York City during the third week of May, the last full week of that month's sweeps period. The networks announce their fall primetime schedules, including tentative launch dates (i.e., fall or midseason) for new television programming, which may be "picked up" the week before. The programming announcements themselves are usually augmented with clips from the new television series, extravagant musical numbers, comedic scenes, and appearances by network stars, and take place at grand venues such as Lincoln Center, Radio City Music Hall, or Carnegie Hall. It is also the time when it is announced (by virtue of not being on the fall schedule) which shows are canceled for the next season. In recent years, the networks have mostly revealed this information to the public a few days before the actual presentation. Most cable networks present earlier in the spring since they usually program for the summer months; press attention to these announcements is usually much lighter.
Originally, before networks could own shows, the fights were with studios over number of episodes ordered and license fees. The license fee is what the network gives the studio to produce the show. The network was allowed two airings. If the cost of the show was more than the license fee then the studio paid the difference. The networks made their money by selling commercial time.As a bit of context, the television networks have spent more than half their lives under predictions of eminent demise. Go back to the late 70s and early 80s and you'll find columnists speculating that cable and the VCR would kill off at least one of the big three before 1990. These columns were recycled over the years with the advent of digital cable, DVDs, video games, the internet, the boom in original programming, streaming services and probably a few other developments I can't think of at the moment.
So if a series was cancelled after thirteen weeks and the studio shelled out a lot of additional costs it took a bath. But if the show was a hit, like say FRIENDS, then the studio owned it outright. At the time, syndication was the brass ring. Warner Brothers has made billions on FRIENDS. 20th continues to rake in money from MASH. It’s like a slot machine that just keeps paying out for over forty years.
Studios made so much money that the networks eventually cried poverty and lobbied the government to participate. They won and were allowed to own studios and shows. There was concern that the networks would then just pick up their own shows and squeeze out outside studios. "Oh no," they promised, "Our goal is to get the highest ratings so we'll buy the best shows regardless of who produces it." You know the result. For the most part networks only picked up shows they owned. If they bought a show from an outside studio they usually required partnership.
If you had an ownership stake in a series (let's say you were the writer/creator/showrunner) you now had another partner. Sort of reminds you of the Sopranos,’ doesn’t it? And even the big syndication dollars were in jeopardy. Why? Because networks began buying cable networks and selling their shows essentially to themselves at reduced rates. The ownership partners were undercut again. The networks profited in that they had quality programming for their upstart networks and they alone profited on the advertising. This prompted several lawsuits by folks with ownership stakes, like Alan Alda.
All of these new sources of competition continued to erode (losing a monopoly will do that), but they remained one of the dominant forces in the media landscape and thanks to deregulation and industry consolidation, companies like NBC/Universal/Comcast have unprecedented freedom to abuse market power.
We're thirty-plus years into an experiment in laissez-faire economics and certain conclusions are difficult to avoid.

What does Mark Thoma think about Jimmy John's?
Sometimes articles just demand to be paired up.
From Professor Thoma:
The second view of inequality, one that is gaining traction, emphasizes market imperfections and the exploitation of power relationships. Adherents to this school of thought believe that market systems have an inherent tendency toward large monopolies, and this tendency has been furthered by technological change, globalization, and economic strategies by incumbent firms that make it hard for new competitors to enter the market.
As monopoly power becomes established, those with economic and political power can capture the political process and prevent the enforcement of antitrust law and regulatory change that could threaten their market dominance. The political power large firms have can also be used to undermine unions destroying any chance workers have to bargain on equal footing for wages. This leads to even higher profits and more inequality.
...
These courses do spend time looking at the economic consequences of monopolistic completion, oligopolies, and monopolies, though not enough in most cases. But students are left with the impression that these market structures are aberrations from the norm rather than the normal state of affairs. That needs to change. And what is missing altogether in most cases is a discussion of power relationships. Quoting Professor Stiglitz once again, “historically, the oppression of large groups – slaves, women, and minorities of various types – are obvious instances where inequalities are the result of power relationships, not marginal returns.”
I'm not an economist so obviously anything I say on the subject should be viewed skeptically, but I would assume that when people in power routinely demand concessions from those without power and those concessions are of slight value to those making the demands while being onerous to those complying, we have strong evidence of an unhealthy power dynamic.
From Kerry Close:
Of the workers who have signed non-competes, fewer than half say they had access to trade secrets that a potential rival company could take advantage of. What’s more, 37% of workers say they have signed non-compete agreements at some point in their careers.
While engineering and computer/mathematical occupations have the highest prevalence of non-competes, the agreements aren’t exclusive to highly-skilled professions. For instance, 15% of workers without four-year college degrees are subject to non-competes, while 14% of employees earning less than $40,000 a year have signed a non-compete. That’s despite the fact that employees in both sectors are about half as likely to possess trade secrets than more highly educated and higher-earning counterparts in the work force.
...
In one of the most puzzling and criticized example of non-competes, fast food sandwich chain Jimmy John’s requires workers to promise they won’t work for a competitor, defined as a nearby business that derives at least 10% of its revenue from sandwiches, within two years of leaving their job. Specifically citing Jimmy John’s, two senators introduced a bill last summer that would prohibit the use of non-compete agreements for employees earning less than $15 an hour, $31,200 a year or the minimum wage in the employee municipality. It would also require employers to tell prospective hires that they may be asked to enter into such an agreement.

The shift from “is not” to “is” framing or when the irresistible appeal of not-Trump meets the immovable obstacle of is-Cruz
[I wrote this (or at least dictated it to my phone) a month ago back when Cruz was still in the race, albeit fading fast. The tenses are, as a result, occasionally a bit weird but I'm still comfortable with the basic thesis.]
These two posts from TPM got me thinking:
From Trumpmentum. Yes, Trumpmentum. Really.
And from New York City GOP Gala Crowd Ignores Ted Cruz During His Speech
Though for very different reasons, both Romney and Trump were front runners who were highly unacceptable to a substantial faction of the party. The result has been two consecutive Republican primaries with a distinctive piston-like action. On a fairly regular basis, some alternative candidate suddenly moves up in terms of polls, coverage, buzz, and expectations, peaks briefly then goes back down.
As mentioned before, game theory gives us a pretty good model of how voters unhappy with the front runner can converge on a second choice, but I think another theory is needed to explain why these candidates almost always fade.
I would argue that we see a shift in voter thinking when the alternative candidate peaks. On the upstroke the question of whom to vote for is framed as who is a viable alternative? While on the downstroke the question is framed as is this a viable candidate? Put another way, the theory is that when people looking for a focal point, they are on the lookout for points that might attract other people; after they've converged, they start examining the choice more critically.
Another somewhat complementary theory is that some people will tentatively move toward a possible focal point only so long as others appear to be converging around that point. I want to be careful with this one. Momentum is perhaps the most overused term in political reporting, and I generally tune out when I hear it. However, in a case where voters unhappy with a front runner are trying to coordinate their efforts and present a united opposition, I think the concept makes sense.
(If all this is true, then both Nate and Nate got it completely backwards when they repeatedly declared Donald Trump to be another Herman Cain. Under these theories Trump was Romney; Rubio and the other candidates who had their brief moment in the sun were Cain.)
Being down to a two-man race changes the dynamic quite a bit, but we are still seeing a similar pattern. A week of bad news for Trump gets voters (and perhaps more importantly analysts and pundits) thinking about the possibility of Ted Cruz as a viable alternative and we see something of a bump. Then the thinking shifts to Ted Cruz as an actual candidate...
"Remember, always start from the axiom of EHTD"
These two posts from TPM got me thinking:
From Trumpmentum. Yes, Trumpmentum. Really.
I don't deny this could still happen. It's quite possible. But it is worth noting that in the nationwide GOP primary polls, after a brief Cruz Boomlet (Dead Ted Bounce) Trump's numbers have rebounded and actually appear to be rising again. Yes, rising. (The rise could just be wobbliness in the polls; but he's at least stabilized his support nationwide.) Conventional wisdom was - perhaps still is - that Trump had hit his ceiling and the sheer weight of bad news was pulling him down. That probably wouldn't stop Trump from winning more primaries. But it would likely make it impossible for him to secure 1237 delegates. Meanwhile, Ted Cruz would accrue enough to make him a plausible alternative nominee.
Again, that's not what's happening. Cruz's numbers nationwide are going down, seemingly shedding at least a margin of support to both Trump and Kasich. There's also little doubt that a big win in New York, which seems highly likely, will give him a wave of good press and allow him to reclaim the look of a winner.
Don't get me wrong. I'm not saying that Trump will get 1237 delegates or that he'll be the nominee. I find it hard to figure out or at least game out the chances of any of this - mainly because all the possibilities seem deeply implausible and yet one must happen. What does seem clear to me is this: Conventional wisdom seems to be or has been that Trump had peaked and started to fall with mix of the Lewandowski 'assault', the terrible week with four different positions on abortion, various protester beatings and unified elite GOP denunciation. He likely couldn't be caught by any other candidate. But he might be a 'zombie' plurality winner - still in the lead but so clearly damaged and losing steam that he could with some ease be denied the nomination. But the polls show Cruz is falling and Trump has not just stabilized but actually seems to be gaining steam.
What's not totally clear to me is how much this is being driven by Trump and how much people seeing Ted Cruz is turning people against him. Remember, always start from the axiom of EHTD (Everybody Hates Ted Cruz). And you can't go far wrong. Clearly the anti-Cruz wall Cruz built in the Senate is holding strong. But whether it's more strength from Trump or the failure of the anti-Trump stalking horse doesn't really matter. The upshot is the same. Trump is getting stronger, not weaker. And that portends bad things for any effort to deny him in Cleveland.
And from New York City GOP Gala Crowd Ignores Ted Cruz During His Speech
Sen. Ted Cruz's (R-TX) speech at the New York City Republican gala on Thursday night was met with a cool reception from the crowd, who spoke amongst themselves and milled about as Cruz delivered his campaign stump speech.
"I will admit to you, I haven’t built any buildings in New York City," Cruz said at the beginning of his address, drawing some applause, according to Buzzfeed News.
But it went downhill from there.
As Cruz continued with his speech, his applause lines drew little attention from the New York Republicans at the dinner, according to NBC News. The sound of chatter and cutlery on plates grew louder as Cruz's speech went on, according to Buzzfeed News. People also began wandering the room to chat with acquaintances at other tables.

TFA's enrollment woes – the importance of putting numbers into context
This Washington Post piece by Emma Brown on the problems at Teach For America is interesting on a number of levels, definitely something you should take a look at if you've been following the story. [emphasis added]
This certainly sounds like a big deal, but a few seconds on Google and some very quick, back of the envelope calculations reveal just how small these numbers are in relative terms.To put things in perspective, there are over 3 million full-time teachers. A drop of several hundred applicants won't be all that noticeable, even if all of them were going to high-need areas (and quite a few aren't).
As previously discussed, TFA is a minor player viewed as a supplier of teachers, but in terms of fundraising, it's a big deal.
From Wikipedia:
If all TFA did was recruit six thousand new teachers a year, there would be no way to justify these budgets, but of course, that was never the main focus. TFA is an advocacy group with a stated mission to "enlist, develop, and mobilize as many as possible of our nation's most promising future leaders to grow and strengthen the movement for educational equity and excellence." [again, emphasis added]
Though the organization is sometimes coy on the point, the focus has never been on leading from the classroom. The positions of real value are administrators, think-tank fellows, politicians, and education journalists, and the program is set up to help them rise to those spots, often at exceptional speed. We can go back and forth on whether a decline in the influence of TFA would be a good thing or a bad, but we probably don't need to worry about what the loss of "several hundred" prospective TFA mombers will do to the teaching pool.
Applications to Teach for America fell by 16 percent in 2016, marking the third consecutive year in which the organization — which places college graduates in some of the nation’s toughest classrooms — has seen its applicant pool shrink.
...
TFA received 37,000 applications in 2016, down from 57,000 in 2013 — a 35 percent dive in three years. It’s a sharp reversal for an organization that grew quickly during much of its 25-year history ["grew quickly" is certainly true in terms of budget, not so much in terms of members. See below -- MP], becoming a stalwart in education reform circles and a favorite among philanthropists.
Teach for America now boasts 50,000 corps members and alumni; some have stayed in the classroom and others have gone on to work in education in other ways, joining nonprofits, running for office and leading charter schools. Its alumni include some of most recognized names in public education, including D.C. Schools Chancellor Kaya Henderson and her predecessor, Michelle Rhee.
...
The declining interest means that TFA is providing fewer corps members to school districts each year: The organization generally accepts about 10 percent of its applicant pool, and it refuses to lower its bar for admission, [Elisa Villanueva Beard, TFA’s chief executive] wrote. This year’s corps is likely to be several hundred smaller than last year’s.
“These shortfalls matter. Corps members are good at their work,” she wrote. “Our school and district partners want to hire far more of them than our current recruitment effort is producing.”
This certainly sounds like a big deal, but a few seconds on Google and some very quick, back of the envelope calculations reveal just how small these numbers are in relative terms.To put things in perspective, there are over 3 million full-time teachers. A drop of several hundred applicants won't be all that noticeable, even if all of them were going to high-need areas (and quite a few aren't).

2003 | 15,708 | 1,646 | 20 | $29.8M |

One of these I'm actually going to write that ddulite mega-thread...
And when I do, I'm definitely going to use extensive quotes from this beautifully brutal piece by Evgeny Morozov.
Of course, any discussion of embarrassing ddulite hype will include an inevitable section on TED Talks,,,
So much BS, so little time.
What the Khannas’ project illustrates so well is that the defining feature of today’s techno-aggrandizing is its utter ignorance of all the techno-aggrandizing that has come before it. The fantasy of technology as an autonomous force is a century-old delusion that no serious contemporary theorist of technology would defend. The Khannas have no interest in intellectual history, or in the state of contemporary thought about technology. They prefer to quote, almost at random, the likes of Oswald Spengler and Karl Jaspers instead. This strategy of invoking random Teutonic names and concepts might work on the unsophisticated crowds at Davos and TED, but to imagine that either Spengler or Jaspers have something interesting or original to tell us about cloning, e-books, or asteroid mining is foolish. “A new era requires a new vocabulary,” the Khannas proclaim—only to embrace the terminology that was already in place by the end of the nineteenth century. They may be well-funded, but they are not well-educated.
Their promiscuous use of the word Technik exposes the shaky foundation of their enterprise—as well as of many popular discussions about technology, which inevitably gravitate toward the bullshit zone. To return to Harry Frankfurt, the key distinction between the liar and the bullshitter is that the former conceals “that he is attempting to lead us away from a correct apprehension of reality,” whereas the latter conceals that he is not interested in reality at all. The bullshitter “does not care whether the things he says describe reality correctly. He just picks them out, or makes them up, to suit his purpose.” To suggest that Parag and Ayesha Khanna—and numerous pundits before them—might be pursuing purposes other than describing—or improving—reality is almost self-evident. (A look at the website of the Hybrid Reality Institute would suffice.) The more interesting question here is why bullshit about technology, unlike other types of bullshit, is so hard to see for what it is.
It is here that the Khannas stand out. Technik, as they use this term, is something so expansive and nebulous that it can denote absolutely anything. Technik is the magic concept that allows the Khannas to make their most meaningless sentences look as if they actually carry some content. They use Technik as a synonym for innovation, design, engineering, science, mastery, capital, the economy, and a dozen other things. It is what fixes cities, reinvigorates social networking, and grants us immortality. Technik is every pundit’s wet dream: a foreign word that confers an air of cosmopolitanism upon its utterer. It can be applied to solve virtually any problem, and it is so abstract that its purveyor can hardly be held accountable for its inaccuracies and inanities.
Of course, any discussion of embarrassing ddulite hype will include an inevitable section on TED Talks,,,
I can surmise why the Khannas would have wanted to write this book, but it is not immediately obvious why TED Books would have wanted to publish it. I must disclose that I spoke at a TED Global Conference in Oxford in 2009, and I admit that my appearance there certainly helped to expose my argument to a much wider audience, for which I remain grateful. So I take no pleasure in declaring what has been obvious for some time: that TED is no longer a responsible curator of ideas “worth spreading.” Instead it has become something ludicrous, and a little sinister.
Today TED is an insatiable kingpin of international meme laundering—a place where ideas, regardless of their quality, go to seek celebrity, to live in the form of videos, tweets, and now e-books. In the world of TED—or, to use their argot, in the TED “ecosystem”—books become talks, talks become memes, memes become projects, projects become talks, talks become books—and so it goes ad infinitum in the sizzling Stakhanovite cycle of memetics, until any shade of depth or nuance disappears into the virtual void. Richard Dawkins, the father of memetics, should be very proud. Perhaps he can explain how “ideas worth spreading” become “ideas no footnotes can support.”
So much BS, so little time.

The wages of bad journalism are Trump
A number of commentaries have sprung up trying to argue that the rise of Trump shows that democracy is fatally flawed and that we should think about transferring more power to "the right sort of people" (the elites, thought leaders, the political and journalistic establishment, etc.). One of the many flaws of this argument is that a careful survey of how we got here shows that the vast majority of the blame goes to the elites, thought leaders, the political and journalistic establishment, etc.
One of the few establishment figures who has been getting the story right, Paul Krugman, has a post up today that beautifully illustrates the point.
In any system with even minimal standards of accountability, neither Kudlow nor Moore would still have careers in media or economics or politics. Instead, not only are they still employed, they are treated with sufficient respect that Donald Trump is able to improve his respectability by hiring them.
One of the few establishment figures who has been getting the story right, Paul Krugman, has a post up today that beautifully illustrates the point.
At some point in the past twenty or thirty years journalists (or probably more preciselyeditors and publishers) decided that once someone had been recognized as an authority, that person was in for life. You could be a complete babbling idiot, a raging bigot, and about as accurate as a knave in a knight /knave puzzle. It wouldn't matter. Once on the list, you will be treated as a sober and credible source until the day you die or until concerned family members have you institutionalized for your own good.Still boggled by reports that Trump, having realized that the numbers on his tax plan aren’t remotely credible, has decided to fix things by bringing in as experts … Larry Kudlow and Stephen Moore. I mean, at some level this was predictable. But it still tells you a lot about both Donald the Doofus and his chosen party....I mean, Kudlow is to economics what William Kristol is to political strategy: if he says something, you know it’s wrong. When he ridiculed “bubbleheads” who thought overvalued real estate could bring down the economy, you should have rushed for the bomb shelters; when he proclaimed Bush a huge success, because a rising stock market is the ultimate verdict on a presidency (unless the president is a Democrat), you should have known that the Bush era would end with epochal collapse. And then there’s Moore, who has a similarly awesome forecasting record, and adds to it an impressive lack of even minimal technical competence. Seriously: read the CJR report on his mess-up over job numbers:The recurring “oops,” intended as a dig at Krugman, took on an unintended irony after Abouhalkah discovered that Moore’s numbers did not match those of the Bureau of Labor Statistics.In fact, Moore later acknowledged, he was using BLS numbers not from “the last five years” but from an earlier five-year period: December 2007 to December 2012. Focusing on that period is arguably dubious, because the span captures the depths of the Great Recession and the housing crash, which hit some states harder than others—and whose impact likely would have swamped any tax-rate effect. There are other issues with the quality of Moore’s argument, too, like its glancing-at-best treatment of how factors like housing costs shape population and job growth.In any case, Abouhalkah found, Moore’s numbers were wrong even for 2007-12, in ways that complicated the “low taxes = more jobs” message.Texas did not gain 1 million jobs in the 2007-2012 period Moore measured. The correct figure was a gain of 497,400 jobs.Florida did not add hundreds of thousands of jobs in that span. It actually lost 461,500 jobs.New York, with [its] very high income tax rates, did not lose jobs during that time. It gained 75,900 jobs.Oops, indeed.Of course, Moore remains the chief economist at Heritage. And maybe Trump believes that this is a certificate of quality, that anyone in that position must be a real expert.
In any system with even minimal standards of accountability, neither Kudlow nor Moore would still have careers in media or economics or politics. Instead, not only are they still employed, they are treated with sufficient respect that Donald Trump is able to improve his respectability by hiring them.

So speaks a person who has never lived with room-mates
This is Joseph.
Kevin Drum wonders about apartments with common living and dining areas, but private bedrooms and baths. The reason I would be skeptical about this arrangement is that you end up with whomever should happen to rent one of the units. If a group of people pool resources to purchase an apartment then they get to pick who they live with. Even so, these arrangements often end in a messy or unfortunate way. It's the same in college (I lived in a dorm like this once, except with a shared bathroom) in that you have the pressure release of this living arrangement being time limited (and, even then, it can be pretty tough).
So what happens when your apartment mate is loud at night? Or does something illegal? Or is very messy? Who picks what goes on the TV (I remember this as a non-trivial issue in student residences)?
This strikes me as an endless series of room-mate fights. At some point, the shared kitchen is likely to end up in a bad state as that is where bad behavior (dirty dishes, food "borrowing", unsanitary counters) is likely to first peak. The dorm I lived in mitigated this somewhat using maid service, but it was not a perfect fix.

It's the same in college (I lived in a dorm like this once, except with a shared bathroom) in that you have the pressure release of this living arrangement being time limited (and, even then, it can be pretty tough).
So what happens when your apartment mate is loud at night? Or does something illegal? Or is very messy? Who picks what goes on the TV (I remember this as a non-trivial issue in student residences)?
This strikes me as an endless series of room-mate fights. At some point, the shared kitchen is likely to end up in a bad state as that is where bad behavior (dirty dishes, food "borrowing", unsanitary counters) is likely to first peak. The dorm I lived in mitigated this somewhat using maid service, but it was not a perfect fix.

Aleatoricism and Social Media
Often when I'm writing a post, I realize that what I had intended as a supporting passage would work better freestanding. In this case, I was revisiting an old thread about how the vast majority of even the smartest journalists and politicians on Twitter don't understand Twitter. Part of the problem is the tendency to think that you can simply cut up something linear and structured into 140 character increments and call them “tweets.”
This is one of those cases where the medium most definitely is the message, and the medium is fast and random with people dropping in and out unpredictably and each reader having a different context based on who he or she is following and what's on his or her screens. In order to effectively use Twitter, you have to channel your inner McLuhan..
All of which got me to thinking about the way previous writers have tried to incorporate the random into their work.
Bryan Stanley Johnson (1933–1973) wrote an experimental novel The Unfortunates (1969), which was published in separate sections, consisting of a "first" and a "last" section, with the sections in between allowed to be shuffled randomly by a reader. This was an attempt to reproduce the randomness of personal memory. The overall narrative is about a sports journalist traveling to a city, to cover a football game, and recalling events and people from years earlier when he had lived in the city.I wonder if there's an online version of The Unfortunates. It would seem to be a natural fit.

Product placements and hidden costs
Intrusive product placement was one of the reasons I stopped watching White Collar. The annoyance wasn't up there with the plot holes and character inconsistencies, but it was a factor. The spots were so clumsy and blatant that I wondered if they were meant as a protest by the writers, directors, and actors. Either way, it was a major distraction in a show that couldn't afford it.
In the television market of 2016, the field is so crowded that every viewing choice comes with opportunity costs. By choosing to watch Veep or Kimmy Schmidt or Silicon Valley or any of the dozen or so of the shows you really do mean to get around to. That level of competition for viewers heightens what has always been a perverse incentive in most corporations and the delayed, the hidden, the intangible.
When an executive suggests a change that saves money or brings in revenue at the cost of quality or customer loyalty, the positives are immediately evident; the negatives (assuming they are recognized at all) are usually delayed until the executive has moved up and out of the blast radius. In a market where all shows have to fight to hold on to viewers, that can deadly.

How a hit show loses (or perhaps "loses") money
This is one of those cases where threads may or may not be colliding. The following could be yet another story of Hollywood cost spirals. We have lots of unambiguous evidence that things are getting out of control. What's more, these examples it into a larger narrative of cost shooting up in the very areas where technology are to be driving it down.
On the other hand, we could have just another instance of a far older and better established genre, the Hollywood accounting story. There is a long history of films that obviously turned huge profits being labeled as money losers when the time came to pay contributors their share.
Regardless of which version you pick, it is interesting and always useful to look at some actual numbers when trying to follow a business story.

Puzzle and Problem-solving videos [Doublet edition] – now slightly less beta
First the usual caveats. These videos still aren't all that pleasing to either the eye or the ear (which doesn't leave a lot of senses to engage). The plan is still to focus first on concept then on specific content while hopefully keeping the production values at least adequate. For example, recording the audio in a relatively quiet closet-sized hallway to get a reasonably clean track and ignoring the weird acoustics and stilted, choppy delivery that comes from wrestling with a jury-rigged arrangement while trying to narrate.
The concept is a series of math video (initially concentrating on puzzles) that focus less on specific problems and more on problem-solving. The video embedded here talks about analyzing problems to see what makes some easy and others difficult, then seeing if we can use that information to suggest strategies for tackling the more challenging ones. In the follow-up ("turn GRASS GREEN" -- also from Carroll), I talk about flipping problems and working forwards then backwards then forwards... In the Kakuro video I discuss finding footholds. In a couple based on Dudney puzzles, I cover mixing algebraic and trial-and-error solutions to be better guessers. You get the picture.
I'm more or less satisfied with the concept and content (or at least with the direction they're headed) but production and promotion still have a long way to go and I'm not entirely certain how to proceed. A few years ago, if you found a good niche and posted some videos of acceptable quality, there was a decent chance that you'd find an audience through organic search. Based on conversations with people who've worked with SEO, that's very difficult now between the competition and Google changing its algorithms to crack down on people gaming the system (which creates a lot of collateral damage among small players).
I'll be exploring other ways of promoting the videos starting here.If you're interested in the approach I outlined earlier or just in puzzles in general, please check this out (feedback is always appreciated) and keep an eye out for future installments. If you like what you see in terms of content, spread the word around. I'm getting advice from some acquaintances who work in video production so the quality on that side should definitely be improving.
Maybe I'll get around to a post on...
- The extraordinary value of name recognition in the 21st Century built around this post from Ken Levine.
- Exploring (or at least seconding) the points Paul Campos makes in "The key to a more egalitarian society is for everyone to go to elite colleges."
- Indulging in a bit of schadenfreude on how the establishment press's quarter century of tolerating increasingly shoddy and sensationalistic reporting is catching up with them in the form of the Trump campaign, as explained by Mr. Pierce.
- I have great respect for the crowd at FiveThirtyEight (when they're good they're very good), but given their track record, is there any question you'd less like to hear them tackle than Why Did The 'Stop Trump' Movement Fail?
- Connectography is the name of an actual book and not just the title for a parody TED Talk.
- Tierney Sneed does a good job pointing out the limits of the Goldwater analogy. Jon Huntsman proves her point.

Dean Dad on Zero Sum Performance
This is Joseph.
From Dean Dad:
Where I have seen this system thrive is in very high reward environments. Only one actress could be cast to play "Rey" in the new star wars film (no matter how good the second best applicant was), but there are no shortage of volunteers because the pay-off is so great.
But placed into a less highly leveraged environment and it is a recipe for lowering motivation and, occasionally, penalizing the colleges that take on the toughest challenges. We all want to think that we are so awesome that we can do amazing things with tough problems, and sometimes people do, but it can be a thin line between that and being set up to fail.
From Dean Dad:
In most states or systems with performance funding, the overall level of funding -- the pie to be sliced, if you prefer -- is either flat or declining. Which means that if everyone improves by the same five percent, then everyone gets the same zero percent increase. You may be making progress, but you’re still essentially running in place. Worse, if you improve by three percent but the statewide average is five, you actually lose ground.I find these sort of systems to be extremely tough environments to build motivation and success in, so I am glad that they are being scrutinized. One issue is that it creates some very perverse incentives. Consider this in a human resources context -- you do well at your job, get promoted, and now you are at the bottom of the ranking for the new rile you are in. If the bottom group tends not to survive (long term) it suggests promotion is bad. Or that politics will be played to make a promotion survivable, which can be pretty toxic.

Context only counts if it shows up in the first two dozen paragraphs
The New York Times has a good piece on the impact of voter ID laws but I do have a problem with a few parts (or at least with the way they're arranged).
More than twenty paragraphs later.
I shouldn't have to say this but, if a story contains claims that the reporter has reason to believe are false or misleading, he or she has an obligation to address the issue promptly. Putting the relevant information above the fold is likely to anger the people who made the false statements, but doing anything else is a disservice to the readers.
In the third paragraph, we have two conflicting claims that go to the foundation of the whole debate. If election fraud is a significant problem, you can make a case for voter ID laws. If not, it's difficult to see this as anything other than voter suppression. This paragraph pretty much demands some additional information to help the reader weigh the claims and the article provides it...
Stricter Rules for Voter IDs Reshape Races
By MICHAEL WINES and MANNY FERNANDEZ MAY 1, 2016
SAN ANTONIO — In a state where everything is big, the 23rd Congressional District that hugs the border with Mexico is a monster: eight and a half hours by car across a stretch of land bigger than any state east of the Mississippi. In 2014, Representative Pete Gallego logged more than 70,000 miles there in his white Chevy Tahoe, campaigning for re-election to the House — and lost by a bare 2,422 votes.
So in his bid this year to retake the seat, Mr. Gallego, a Democrat, has made a crucial adjustment to his strategy. “We’re asking people if they have a driver’s license,” he said. “We’re having those basic conversations about IDs at the front end, right at our first meeting with voters.”
Since their inception a decade ago, voter identification laws have been the focus of fierce political and social debate. Proponents, largely Republican, argue that the regulations are essential tools to combat election fraud, while critics contend that they are mainly intended to suppress turnout of Democratic-leaning constituencies like minorities and students.
More than twenty paragraphs later.
Mr. Abbott, perhaps the law’s most ardent backer, has said that voter fraud “abounds” in Texas. A review of some 120 fraud charges in Texas between 2000 and 2015, about eight cases a year, turned up instances of buying votes and setting up fake residences to vote. Critics of the law note that no more than three or four infractions would have been prevented by the voter ID law.
Nationally, fraud that could be stopped by IDs is almost nonexistent, said Lorraine C. Minnite, author of the 2010 book “The Myth of Voter Fraud.” To sway an election, she said, it would require persuading perhaps thousands of people to commit felonies by misrepresenting themselves — and do it undetected.
“It’s ludicrous,” she said. “It’s not an effective way to try to corrupt an election.”
