Some good news for the new year

From Mental Floss:

In September, a cryptic update to cartoonist Gary Larson’s The Far Side website hinted that something new might be in store for fans of the popular single-panel comic strip. This week, Larson and his syndicate, Andrews McMeel Universal, made it official. The irreverent cartoon, which originally ran from 1980 to 1995 and explored the perils of anthropomorphic cows and science run amok, will now be available online for the first time. But it won’t be strictly archival material: Larson plans to periodically revisit his bizarre world with new art.

Monday Tweets (because spending New Year's Eve on Twitter would just be wrong)

Welcome to the world of climate gentrification.

"Little Haiti’s elevation  is 7 feet above sea level with pockets in the neighborhood that go as high as 14 feet above sea level. By comparison, Miami Beach is about 4 feet above sea level."

"One of these things is not like the other..."

Welcome to LA

Klein is making a tremendously important point here

It's a complex issue, but my initial impression is that this would have more pros than cons, assuming the city could force it through.

Of course C-level executive compensation is rational.

NYT = Hal900 Admitting that they were wrong drives both insane.

Must read

It's the wrapping paper budget that kills you.

This is a big story.

Kanefield has become the essential legal commentator for the Trump years. For those who lack the patience for really long threads, she also has blog versions.

This remains one of the best indications of real expertise in all fields.

"East of Lincoln"-- updated

Now with soundtrack.

Monday, April 9, 2018

I've never been a beach person. There are (or at least used to be) some exceptions but most of these towns are for me nice places to visit but a little too bland and way too pricey to want to live there.

I know people, however, who have trouble imagining living anywhere else. One of them, a long time Venice resident, described it like this. He had lived in other parts of the city when he first came here but said he never felt he was truly in LA until he made it all the way west. He compared the feeling to that of a pioneer crossing the continent in a covered wagon only to die of thirst in the desert just short of California.

Venice Beach used to have a seedy, bohemian reputation, just the sort of place you'd expect Jim Morrison to hang out. These days, the feel is definitely upscale, the rough edges have largely been worn away, and the crime you encounter is less likely to involve gangs and drugs and more likely to involve Silicon Beach Ponzi schemes.

One of the last holdouts of old Venice was Abbott's Habit, a decidedly non-corporate coffeehouse that long held a corner of Abbott Kinney, the street now known for pop-up shops, trendy restaurants, and places where you can get bone marrow ice cream (no, really).

I happened to be in Venice the day that Abbott's Habit closed. It was packed with regulars as a long list of local musicians played short sets to say goodbye. One song in particular captured the mood of the event (I'm sure it's out there somewhere on the Internet but I haven't been able to find it). The chorus went something like this, "when I get east of Lincoln, my heart starts sinkin'."

The Lincoln in question is the stretch of the Pacific Coast Highway that runs north and south through that part of town and informally divides the "beach" community from the "non-beach" areas. To live west of Lincoln means to have cool ocean breezes throughout the summer, to be able to walk down to the boardwalk, and generally to feel yourself part of the vibe.

Every time the singer got the chorus, the crowd nodded in melancholy appreciation. This was a big part of how they had defined their community and, to a degree, themselves. Now, many were being priced out of the area and, more importantly, those who stayed or returned for a visit knew that their Venice was gone regardless.

While it certainly lacks the emotional resonance for the new residents, "west of Lincoln" has never had more economic importance and perhaps never more social value. Venice Beach has become one of those places where well-off people want to live and, more to the point, one of those places where well-off people want to brag about living. There's nothing especially objectionable about this (most non-native born Angelenos have at least occasionally taken a certain pleasure in telling friends back east stories of beautiful weather and celebrity encounters), but it can have important implications for our urban planning discussion.

Many of the arguments we hear about density and transportation are strongly dependent on some rather simplistic assumptions about linear relationships and fixed demand. Why people live where they live is almost always complicated and seldom monocausal. If the discussion doesn't start reflecting some of that complexity, we are in danger of making some very big mistakes.

(And, yes, the bone marrow ice cream wasn't that bad.)

American political journalism is better than has been in a quarter century.

No snark.

No qualifiers.

One of the good things to come out of the past few years was that events have forced journalists to finally start facing some ugly truths about the profession, that they had abdicated their responsibility to inform, that they had used self-serving definitions of fairness as an excuse for caving in to pressure, that they not only tended to reduce complex stories to simplistic narratives but often let those narratives be dictated to them.

While we still have a ways to go, things have improved greatly. The conversation used to be lead by hacks like Howard Kurtz and tribalists like Jack Shafer. Now, the leading voices are arguably Margaret Sullivan and Jay Rosen, both of whom spent years playing Cassandra, having their prescient warnings ignored as things kept getting worse.

I'm sure there are exceptions, but every mainstream press institution I can think of at the moment has improved from its low point. I routinely find myself impressed by a piece of reporting or analysis from CNN (something that never used to happen). Even the Chuck Todds are starting to stand up on their hind legs.

This process of acknowledging and correct flaws has proved most difficult for the New York Times and NPR. The first is held back by compulsive self-congratulation and the axiomatic belief that is it is the world's best newspaper. The second has almost convinced itself that its now instinctive submissive crouch is a sign of maturity rather than cowardice.

Nonetheless, both are showing progress. This NYT piece represents a big step forward in acknowledging the situation, if not the gray lady's role in it.

Better still is this interview by Steve Inskeep, where he calmly but forcefully deals with the disinformation.

And yes, that Pam Bondi.

White Christmas in LA -- drive carefully

Probably later today...

One of the many things I didn't expect when I moved to LA early in the 2000s was that I would still have to adjust my travel plans for winter storms

A cold winter storm will bring widespread rain and mountain snow to Southern California late Wednesday into Thursday, the National Weather Service said.

Snow levels will dip as low as 2,500 feet, and up to 8 inches could accumulate in the Antelope Valley. The Cuyama Valley could receive 3 inches of snow. Higher elevations of the L.A. and Ventura county mountains could see up to 2 feet of snow, especially above 6,000 feet.

Merry Christmas from Little Nemo

It's the thought that counts

Sixties television was filled with heart-warming Christmas episodes often featuring orphans

The Untouchables got a lot of criticism during its original run for its depictions of violence. Can't imagine why.

"The unicorn is a mythical beast."

I realized that now when I hear the word "unicorn," I think of a tech bro pitching a 21st Century Ponzi scheme to some clueless venture capitalists. Here's something to wash the taste of all of those WeWorks and Pelotons out of your mind.

Revisiting the catharsis thread

Recent events have got me thinking about this point from four years ago.
I've been arguing for quite a while now that we need to pay more attention to the catharsis in politics (such as with the reaction to the first Obama/Romney debate), particularly with the Tea Party.  Conservative media has long been focused on feeding the anger and the outrage of the base while promising victory just around the corner. This has produced considerable partisan payoff but at the cost of considerable anxiety and considerable disappointment, both of which produce stress and a need for emotional release.

There's a tendency to think of trading political capital for catharsis as being irrational, but it's not. There is nothing irrational about doing something that makes you feel better. That's the real problem for the GOP leaders: shutting down the government would be cathartic for many members of the base. It would be difficult to get the base to defer their catharsis, even if the base trusted the leaders to make good on their promise that things will get better. 
 The difference now is that the head of the party is one of the base.

Planned Parenthood, channeled information and catharsis

This recent TPM post about the looming government shut-down ties in with a couple of ideas we've discussed before. [Emphasis added]

Facing a Sept. 30 deadline to fund the government, GOP leaders in both chambers decided they would fast-track standalone anti-abortion bills in an effort to allow conservative Republicans to express their anger over a series of “sting” videos claiming to show that Planned Parenthood is illegally harvesting the tissue of aborted fetuses. The leadership hoped that with those votes out of the way, the path would be clear for long-delayed bills to fund the government in the new fiscal year, even if those bills contained money for Planned Parenthood.

But anti-abortion groups and conservative House members are not backing down from their hard line. They are reiterating that they will not vote for bills that include Planned Parenthood funding under any circumstances, despite the maneuvering by leaders to vent their outrage over the videos. If anything, anti-abortion groups are amping up the pressure on lawmakers not to back down from the fight.
Here's what we had to say about the GOP reaction to those videos a month ago.

Fetal tissue research will make most people uncomfortable, even those who support it. If you were a Republican marketer, the ideal target for these Planned Parenthood stories would be opponents and persuadables. By contrast, you would want the videos to get as little play as possible among your supporters. With that group, you have already maxed out the potential gains – – both their votes and their money are reliably committed – – and you run a serious risk of pushing them to the level where they start demanding more extreme action.

With all of the normal caveats -- I have no special expertise. I only know what I read in the papers. There's a fundamental silliness comparing a political movement to a business -- it seems to me that in marketing terms, the PP tapes have been badly mistargeted. They have had the biggest viewership and impact in the segment of the voting market where they would do the least good and the most damage (such as pushing for a government shutdown on the eve of a presidential election).
[I really should have said "causing supporters to push," but it's too late to worry about that now.]

I haven't followed the press coverage that closely, but based on what I've come across from NPR and the few political sites I frequent, I get the feeling that the center-left media is more likely to discuss the doctoring of the tapes than to focus on the gory specifics of harvesting fetal tissue. I'd need to check sources like CNN before making a definitive statement, but it appears that the videos are having exceptionally little effect on what should have been their target audience.

Instead, their main impact seems to have been on the far right. The result has been to widen what was already a dangerous rift. The pragmatic wing looks at defunding as a futile gesture with almost no chance of success and large potential costs. The true believers are approaching this on an entirely different level. It has become an article of faith for them that, as we speak, babies are being killed, dismembered and sold for parts. They demand action, even if it's costly and merely symbolic, as long as it's cathartic.

I've been arguing for quite a while now that we need to pay more attention to the catharsis in politics (such as with the reaction to the first Obama/Romney debate), particularly with the Tea Party.  Conservative media has long been focused on feeding the anger and the outrage of the base while promising victory just around the corner. This has produced considerable partisan payoff but at the cost of considerable anxiety and considerable disappointment, both of which produce stress and a need for emotional release.

There's a tendency to think of trading political capital for catharsis as being irrational, but it's not. There is nothing irrational about doing something that makes you feel better. That's the real problem for the GOP leaders: shutting down the government would be cathartic for many members of the base. It would be difficult to get the base to defer their catharsis, even if the base trusted the leaders to make good on their promise that things will get better.

For now, the Tea Party is inclined to do what feels good, whether it's supporting an unelectable candidate or making a grandstanding play. It's not entirely clear what Boehner and McConnell can do about that.

Tuesday Tweets

Starting with some news you can use.

Not Harwood, of course, but how many pundits have used the wealth tax as an example of Democrats risking electability by moving too far to the left?

I've noticed this too.

This should be a bigger story.

When actual engineers talk about drones and flying cars, noise pollution is one of the first things they bring up. Many (perhaps most) journalists skip that issue entirely.

Check out the whole thread.

Baker is terrible at his job.

But at least he has company in the office.

2016 showed us that the press still has a horrible problem with misogyny and that it's especially bad at the NYT.

Too many otherwise sober commentators have bought into the idea that all Trump has to do is hold the base. That line of reasoning never made any sense.

We've got your good billionaire press lords and we've got...

We'll be coming be coming back to this one.

I also wonder if the bankruptcies have something to do with which farmers (and companies) are getting the money.

Sincere question for those out there with relevant expertise, to what extent does the existence of today's unicorns depend on the innovations of the infamous Match King?

And finally, some yak karma.

More on data science

This is Joseph

This is an excellent article on machine learning. In particular I liked this:
As an extreme illustration, an algorithm designed to predict a rare condition found in only 1% of the population can be extremely accurate by labeling all individuals as not having the condition. This tool is 99% accurate, but completely useless. Yet, it may “outperform” other algorithms if accuracy is considered in isolation.
It is even better discussed by Frances Wooley and Thomas Lumley using the example of classification of sexual orientation by facebook. This isn't to say that machine learning isn't useful but the proper penalty functions or sampling characteristics need to be developed (Thomas has a great discussion of this). A simple measure of accuracy is going to fail in all sorts of cases where simple but useless rules do extremely well (most people do not have pancreatic cancer and I can be exceedingly accurate guessing that any one person does not have it). It isn't that the problem is intractable, but that it isn't simply a case of running a technique on whatever data happens to be lying around. Like most worthwhile data science problems, doing the work well is what is hard.

The article also highlights the limitations of the data generating process. Is not having contact with the health system mean one is healthy? In the CPRD it seems like the people without blood pressures (routinely collected during visits to a physician) were both the most healthy and the least. Lack of contact with the medical system is complicated but these participants often form the reference group.

Anyway, go, read, and enjoy.

Choice of metric: the perils of data science

This is Joseph

I was reading this article and I decided it was a good example of how the choice of metrics can really change the answer to a study question. The author concludes that the best general of history was Napoleon:
Among all generals, Napoleon had the highest WAR (16.679) by a large margin. In fact, the next highest performer, Julius Caesar (7.445 WAR), had less than half the WAR accumulated by Napoleon across his battles. Napoleon benefited from the large number of battles in which he led forces. Among his 43 listed battles, he won 38 and lost only 5.
So what was the choice of metric:
Inspired by baseball sabermetrics, I opted to use a system of Wins Above Replacement (WAR). WAR is often used as an estimate of a baseball player’s contributions to his team. It calculates the total wins added (or subtracted) by the player compared to a replacement-level player. For example, a baseball player with 5 WAR contributed 5 additional wins to his team, compared to the average contributions of a high-level minor league player. WAR is far from perfect, but provides a way to compare players based on one statistic.
The problem with this metric is that it presumes that all players have an equal opportunity to accumulate wins. This leads to some odd outcomes:
Napoleon’s large battle count allowed him more opportunities to demonstrate his tactical prowess. Alexander the Great, despite winning all 9 of his battles, accumulated fewer WAR largely because of his shorter and less prolific career.
Now it is true that the historical consensus is that both are good generals. But an unbroken string of impressive victories, against the regional superpower, gives a WAR of 4.370, a quarter of Napoleon's score. I am not sure that the historical consensus is that Alexander was mediocre besides Napoleon because of the number of battles. If anything, there is a perspective that having to fight more battles was actually a sign of a weaker general.  Consider these quotes:
There is no instance of a nation benefitting from prolonged warfare.
For to win one hundred victories in one hundred battles is not the acme of skill. To subdue the enemy without fighting is the acme of skill.
Hence to fight and conquer in all your battles is not supreme excellence; supreme excellence consists in breaking the enemy's resistance without fighting.
The best victory is when the opponent surrenders of its own accord before there are any actual hostilities... It is best to win without fighting.
 All of this isn't to say that I am not in awe of the work done on this project. It was amazing. But it is a good time to reflect on the issues with any one-dimensional metric when trying to evaluate something as complicated as warfare.

Thursday Tweets (Having an exceptionally busy schedule had nothing to do with this scheduling decision.)

Marketplace is the best news show on public radio,

Mike Judge is, once again, on top of it.

One more hit on Peloton

Remember when the secret ballot talk was basically just a joke? People seem to be taking it a little more seriously (though it's still a looong shot)

Normalizing the Ponzi Threshold

The blurb doesn't actually show up in the linked article, but it pretty much captures the gist.
According to the Wall Street Journal, Away sold $150 million worth of luggage in 2018. But if the company is to keep growing, it needs to sell more than just suitcases and weekenders, which are relatively infrequent purchases. Founders Jen Rubio and Steph Korey say their plan is to enter new categories of products that are related to travel, and they’re teasing us with hints of what they might be.

Obviously, the magnitude of the Uber bubble dwarfs any valuation that Away has or is likely to reach,  but as absurd as Uber’s story was, at least it was a tale about big, new things. Smart phone based ride sharing was a genuinely disruptive industry and while it was unlikely that any one company would achieve the dominance (or the profit margins) that Uber promised,  the industry’s potential was substantial enough to get caught up in.  It took a while for the realization that the original model could never support the money that had been poured into it.

With Away, everyone seemed to realize almost immediately that the company on its current path could not be worth 1.4 billion dollars, and yet no one seems particularly bothered by the fact. Instead we get a nonchalant “don’t worry, they’ll think of something.” Given the amounts of money we’re talking about here, that’s an absolutely insane reaction, but in the age of the unicorn, it’s not at all an uncommon one.

On a related note, Away is a horrible business run by creepy people. For more on that, I send you to the good folk at LGM.

Ponzi Thresholds

Another post based on Reeves Wiedeman's Uber article in New York magazine. This one sets up a concept I've been meaning to discuss with the tentative name of a Ponzi threshold. The basic idea is that sometimes overhyped companies that start out with viable business plans see their valuation become so inflated that, in order to meet and sustain investor expectations, they have to come up with new and increasingly fantastic longshot schemes, anything that sounds like it might possibly pay off with lottery ticket odds.

Like I said, this is been bouncing around for quite a while. I may have even slipped in a previous reference that I've forgotten about. There are plenty of potential examples, but the following is the first time I've seen the phenomenon spelled out in such naked terms [emphasis added]:
Meanwhile, in an effort to show potential investors in an IPO that it has multiple revenue streams, Uber has expanded into a variety of industries tangentially related to its core business. In 2015, the company launched Uber Everything, an initiative to figure out how it could move things in addition to people, and when I visited Uber headquarters, the guest Wi-Fi password was a reference to Uber Freight, the company’s attempt to get into trucking. (A former employee said the password often seemed to be a subliminal message encouraging employees to focus on the company’s newest initiatives.) But moving things had its own complications. One former Uber Everything manager said the company had looked at transporting flowers or prescription drugs or laundry but found that the demographic of people who, for example, couldn’t afford a washer and dryer but would pay to have their laundry delivered was a small one. Uber Rush, a delivery service in New York, had become “a nice little business,” the manager said, “but at Uber, you’re looking for a billion-dollar business, not a nice little business.”

It turned out that food delivery was the only area that made much sense, though even that was difficult. In the past year, food-delivery companies SpoonRocket, TinyOwl, Take Eat Easy, and Maple have all ceased operations. Postmates said in 2015 that it could be profitable in 2016, at which point it pushed the date to 2017. Its target is now 2018. “It absolutely does not work as a one-to-one business — picking up a burrito from Chipotle and delivering it,” a former Uber Eats manager said. “It has to be ‘I’m picking up ten orders from Chipotle, and I’m picking up this person next to Chipotle, and I’m gonna drop the burritos off along the way.’ ” Uber Eats has grown significantly, but getting the business up and running had required considerable subsidies, and the manager said it was rumored that a significant portion of the company’s domestic losses were coming from Uber Everything.

Uber’s expansion into an ever-widening gyre of business interests makes sense for a company looking to justify a huge valuation, but it has drawn criticism from some who wonder why the company is moving into so many different markets without becoming profitable in its first one. “It’s a Ponzi scheme of ambition,” Anand Sanwal, a venture-capital analyst, told me. “ ‘We’re gonna raise money on the promise of dominating an industry to come in order to pay for this thing that doesn’t make us money right now.’ ” He had recently conducted an unscientific poll of subscribers to his newsletter asking how many would invest in Uber today, even at a discounted valuation, and 77 percent said they wouldn’t. But the new initiatives have the benefit of keeping everyone excited about the future: In April, Uber held a conference in Dallas to explain why it planned to one day get into flying cars.

That phrase "looking to justify a huge valuation" is one that you need to contemplate for a few moments, let the logical implications wash over you. As I suggested before, like most New York magazine tech writers, Wiedeman does a good job capturing the telling detail, but is reluctant to draw that final Dr.-Tarr-and-Prof.-Feather conclusion, particularly when it threatens a cherished narrative.

There are at least two layers of crazy here. First, hype and next-big-thingism push Uber's value far beyond any defensible level, then, as reality sets in and investors realize that the original business model, though sound, can never possibly justify the money that's been put into the company, Uber's management responds with a series of more and more improbable proposals in order to keep the buzz going.

The phenomenon is not unique to this company but I can't think of another case this big or this blatant. (And they actually used the term "Ponzi scheme.")

What if Mayor Pete is HermanCainHermanCainHermanCain?

I've been meaning to write this up for quite a while, but it keeps getting put off and I'm afraid if I don't get something quick off, events may overtake us again. I'll try to come back to this if we get a chance. 

Those who followed our comments on the 2016 may remember how various pundits (especially Nate Cohn) truly, deeply, desperately wanted to convince us and, more to the point themselves, that Donald Trump was just another Herman Cain and his polls numbers would fall just as quickly.

The analogy never made any sense with Trump, but the idea of an HC3, someone who emerges from the middle of the pack for little apparent reason, seems to be on the verge of challenging the leading candidates only to have that surge evaporate, can be useful.

My take on HC3s is that it's basically a mix of symmetry breaking and a Keynesian beauty contest. Voters are dissatisfied or, at least, uncomfortable with the front runners. As the decision point approaches, second and third tier choices are reexamined.with the considerably lower standard of being an acceptable alternative. Eventually this process converges on a candidate, at which point the scrutiny increases and the bloom is off the rose.

I'm not saying that Pete Buttigieg is a Herman Cain (I'm not even saying Herman Cain was a Herman Cain), but so far, I don't know that I've heard any supporter describe Buttigieg in positive rather than non-negative terms, and that is generally not a good sign.

"I paint what I see" -- RIP Gahan Wilson

Gahan Allen Wilson (February 18, 1930 – November 21, 2019)

Strange to think that of Addams, Wilson and Larson, only the first has remained current and, in his case, only because of misplaced nostalgia for a not-too-successful 60s sitcom.
