The NYT weighs in again on California housing and it goes even worse than expected
The gray lady has doubled down on the liberal hypocrisy housing narrative with a highly promoted video featuring two of the paper's stars and the results are... not good.
Checkout the 3:40 mark.
Obviously, this graph wasn't telling the story they thought it was telling. My first thought was that we were just seeing the impact of the collapse of the housing bubble which didn't particularly support the NYT's argument, but on closer scrutiny (assuming we can trust the x-axis), I realized it was even worse.
If you take a close look, you'll see that the drop started well before the 2008 collapse.
For the record, I don't know if permits issued is the best metric here -- I'd feel much more comfortable if we had an actual researcher to weigh in -- but the decline is a big part of the NYT's argument so we should probably ask ourselves if anything else of note happened in California around this time...
The Schwarzenegger administration went from 2003 to 2011, or roughly...
The three things which the New York Times loves above all others are putting itself in a position of moral superiority, displaying its "impartiality" by criticizing Democrats, and taking condescending shots at other parts of the country. Add in the paper's well-established preference for talking about rich people and the hypocritical California Democrats narrative is nearly perfect which means we're probably in for still more installments.

Food prices
First, there’s a distinct “people on a budget don’t deserve nice chocolate” vibe to many of these comments, which I take umbrage with. Food shaming is pervasive on social media, whether it’s people yucking other people’s yums on a recipe post, commenting on what or how much they are eating, or acting like spending money on a pre-chopped salad kit is tantamount to burning down an orphanage.And while I agree learning to cook is an important life skill and the best form of self-care you can engage in, there are lots of reasons people lean on convenience food — chief among them being convenience, which is right there in the name. Time is our most valuable finite resource, especially in a world that demands a lot of it.

Our annual Toys-for-Tots post
A good Christmas can do a lot to take the edge off of a bad year both for children and their parents (and a lot of families are having a bad year). It's the season to pick up a few toys, drop them by the fire station and make some people feel good about themselves during what can be one of the toughest times of the year.
If you're new to the Toys-for-Tots concept, here are the rules I normally use when shopping:
The gifts should be nice enough to sit alone under a tree. The child who gets nothing else should still feel that he or she had a special Christmas. A large stuffed animal, a big metal truck, a guitar or a keyboard, a large can of Legos with enough pieces to keep up with an active imagination. You can get any of these for around twenty or thirty bucks at Wal-Mart or Costco;
Shop smart. The better the deals the more toys can go in your cart;
No batteries. (I'm a strong believer in kid power);*
Speaking of kid power, it's impossible to be sedentary while playing with a basketball;
No toys that need lots of accessories;
For games, you're generally better off going with a classic;
No movie or TV show tie-ins. (This one's kind of a personal quirk and I will make some exceptions like Sesame Street);
Look for something durable. These will have to last;
For smaller children, you really can't beat Fisher Price and PlaySkool. Both companies have mastered the art of coming up with cleverly designed toys that children love and that will stand up to generations of energetic and creative play.
* I'd like to soften this position just bit. It's okay for a toy to use batteries, just not to need them. Fisher Price and PlaySkool have both gotten into the habit of adding lights and sounds to classic toys, but when the batteries die, the toys live on, still powered by the energy of children at play.

Checking in on over-the-air television beat
These are some of the new OTA superstations you can now pick-up with a set of rabbit ears here in LA. It is a very partial list. I limited it to 2020/21 launches from major media companies in billion dollars or above valuation range (with one possible but unavoidable exception can't leave out Weigel). Several stations from smaller companies were excluded and even with the constraints mentioned I probably missed some examples.
Weigel
MeTV Plus (2021)
ViacomCBS
Fave TV (2021)
NBCUniversal
LX (2020)
Nexstar (formerly Tribune)
Rewind TV
Ryman (Opry Entertainment Group)
Circle (2020)
Entertainment Studios (The Weather Channel et al.)
TheGrio (2021)
E. W. Scripps Company (which bought out the innovative Katz)
Defy TV (2021)
TrueReal (2021)
Newsy (2021)
Tegna (formerly Gannett)
Twist (2021)
I have no solid numbers on this but it's my impression that growth, while leveling off a bit, remains fairly steady and the industry appears to be very stable with close to a hundred percent survival rate among major players (compare that to the cable at this point in its history). It is also worth noting that, with the exception of Ryman, all of these companies already had one or more terrestrial superstations before these new launches. Twelve years in, no one appears to be looking to get out.
There's a big and interesting story waiting to be told about digital over-the-air television. It's part of a still bigger and more important one about why the press somehow collectively decides to focus on certain subjects and narratives and to ignore others.

The rise of the Trump-over-the-Pope faction of the Catholic Church has been one of the most fascinating and disturbing developments of the past few years.
It's even more obvious when you listen to the clip ("or billionaire technocrat") that the source of this position isn't the Pope or the bible; it's Trump/OANN/Tucker Carlson, and to the extent that this stand is religious, the religion is no longer Catholicism.Catholic Priest Fr. Ed Meeks of Towson, MD said in his sermon this past week that vaccine mandates are contrary to the teachings of Jesus: “No earthly king or president or public health official .. gets to dictate what we put into our body, into these temples of the Holy Spirit.” pic.twitter.com/rrU31PvTUh

"Why does he mean more to you than us?”
I come from the buckle of the Bible belt and I stay in touch with friends from back home. Nothing here is that new to me, but even if you've heard this story before, this retelling is worth your time.
What I want to single out here is the way that MAGA and other movements can use members' deeply held (and often reasonable) beliefs to bring them in and then, once they are completely immersed, indoctrinate them into a new worldview that often directly contradicts some of those initial beliefs. This is not a simple process. It happen slowly and stealthily and its effectiveness is not limited to the stupid or the gullible. I've seen smart, reasonable people -- the last ones you'd expect -- get sucked in.
Of course, more often it is the first ones you'd expect, cruel and foolish people with longstanding reactionary tendencies. The closer to the door they start, the easier it is to get them in the temple, but even the most likely recruits are changed by the indoctrination, made less empathetic, more childish, more paranoid and yet more credulous.
From the Washington Post:
Like other families with split political affiliations, they had some yelling matches after Trump took office, especially over the former president’s immigration policies. Claire was a Canadian-born Catholic drawn to the Republican Party by her fierce opposition to abortion, and Trump had won her over with promises to champion her position. Celina, Laurie and their three younger siblings skewed left despite their conservative upbringing in South Dakota. They had never felt such disdain for a politician before.
By the end of the Trump administration, the bounds of their political disagreements had shifted, Laurie recounted, becoming at once more intense and also less about policy and legislation in Washington. They had learned to live with their disagreements over abortion. Now it felt like they were occupying different realities altogether.
Over the course of 2020, amid a presidential election, racial justice protests and a pandemic, the five siblings began to trade increasingly worried text messages and emails about some of the things Claire was saying and posting on Facebook. There were comments they noticed about child trafficking and sacrifice, a key theme of the extremist QAnon ideology. There was her vitriol toward Pope Francis, whom she had referred to as “the anti-Pope.” After Election Day, they took turns pushing back on a stream of disinformation Claire posted online, including the unfounded claim that the CIA murdered U.S. soldiers abroad to help cover up voter fraud.
...“Why is this important enough to compromise your relationships with your kids? Why does he mean more to you than us?”

The mix is always basically the same, a combination of trivial facts/debunked charges and "people are saying" journalism. When the Democrat happens to be a woman, you can also count on a healthy dose of misogyny as well.

Herd mentality certainly plays a role (and is a huge problem for the press in general). Internalizing criticism from conservatives is also a major factor, but there seems to be more to it.

We have twenty years of Harris's job history which is almost impossible to reconcile with this narrative, particularly given Hohmann's reporting is heavy on unsourced rumors (starting with the first sentence), unnamed sources, editorializing ("uneven," "awkwardly"), and bitter ex-employees from almost a decade ago.

Elon Musk may not fully grasp the magnitude of the problem
"All in all, more than 500 such "fragmentation events" have created nearly 130 million bits of debris in Earth's orbit. Those chunks of debris zip around the planet at more than 17,500 mph, or roughly 10 times the speed of a bullet"https://t.co/EURV2ug9ql pic.twitter.com/bc3s6YgkpD

If you're the type of person who closely follows science and technology stories (and since you're reading a blog originally named "Observational Epidemiology," I'm thinking you probably are), you've probably been hearing about the Kessler Syndrome and Musk's Skylink and its imitators could have on this potentially disastrous event. It even got the big narrative treatment at the New Yorker.
Before we dive in, there is one aspect of the story that has been widely misreported.
From Scientific American (2019):
The benefits of mega constellations would be manifold. Blanketing the entire planet with high-bandwidth, low-latency, always-on Internet access means ships out at sea, high-flying planes and people in remote, undeveloped areas (even Antarctica!) will suddenly be connected as never before. “Connectivity is just not [currently] available to everybody,” says Mike Lindsay, a space mission designer at OneWeb. “Half the world lacks an affordable access point to broadband Internet.”
"Manifold" in this case basically meaning one.
We've had satellites delivering broadband internet for about a decade now from companies like Viasat. They use geostationary orbits which means they can cover the entire world with a handful of satellites. The only significant functionality that these enormous low-earth orbit constellations bring to the table is low latency (or ping time), something you want to have for videoconferencing and especially for gaming. It's an embarrassingly small upgrade given the government grants, investor capital and, most of all, potential consequences.
From Business Insider [emphasis added]:
SpaceX has permission from the US government to launch nearly 12,000 Starlink satellites through 2027, though it's asked to launch 30,000 more for a total of nearly 42,000. In either case, SpaceX is on track to form a "megaconstellation" that outnumbers all prior spacecraft ever launched by humanity. If 3% of the maximum planned Starlink constellation fails, that could mean 1,260 dead, 550-pound satellites the size of a desk aimlessly circling the planet. A 2.5% failure rate could mean more than 1,000 inoperative spacecraft.
There were about 3,200 nonfunctional satellites in Earth's orbit as of February, according to the European Space Agency. Many of these dead spacecraft regularly threaten to collide with others and create a space-debris crisis. In mid October, for example, satellite trackers flagged a "very high risk" close pass between a dead satellite and a discarded rocket body, with one company calculating a 10% chance of collision. (Fortunately, they didn't.)
SpaceX says its satellites will naturally deorbit, or burn up in Earth's atmosphere, if their propulsion systems don't work. But that process can take up to five years, according to Starlink's website. In the meantime, defunct satellites rocket around Earth faster than a bullet, with nobody to steer them away from other spacecraft that may fly in their path.
SpaceX did not acknowledge Business Insider's requests for comment. However, in filings to the Federal Communications Commission, SpaceX has downplayed the risk, stating that it "views satellite failure to deorbit rates of 10 or 5 percent as unacceptable, and even a rate of 1 percent is unlikely."
If 1% of its satellites did fail with no capacity to maneuver, the company said, "there is approximately a 1 percent chance per decade that any failed SpaceX satellite would collide with a piece of tracked debris."
The company also claimed that its practices "effectively eliminate the chance that such rates will ever occur."
SpaceX is not alone in pushing to launch large numbers of internet satellites. OneWeb, which the UK government recently purchased out of bankruptcy, has already launched 74 satellites for its proposed constellation of 48,000, while Amazon aims to launch more than 3,200 for its Kuiper fleet. It's unclear how many dead satellites those constellations might also leave in orbit.
...
If the space-junk problem gets extreme, a chain of collisions could spiral out of control and surround Earth in a practically impassable field of debris. This possibility is known as the Kessler syndrome, after Donald J. Kessler, who worked for NASA's Johnson Space Center and calculated in a 1978 paper that it could take hundreds or even thousands of years for such debris to clear up enough to make spaceflight safe again.
...
SpaceX has barely launched 2% of its planned constellation, but it has already had a close call.
In September 2019, the European Space Agency had to maneuver one of its spacecraft at the last minute to avoid possibly colliding with a Starlink satellite. The chance of that crash was 1 in 1,000. While that may sound low, NASA routinely moves the ISS for chances of 1 in 100,000.
The ESA said it had to move its satellite because SpaceX had "no plan to take action." SpaceX said it missed the ESA emails about the issue due to a "bug" in its communications systems.
Overall, close approaches like that seem to be happening more frequently.
"We are seeing recently a decided uptick in the number of conjunctions," Dan Oltrogge, an astrodynamicist at Analytical Graphics, Inc, where he uses a software that has been assessing conjunction data since 2005, told Business Insider. "And it looks to be very well aligned with the new large-constellation spacecraft that have been launched."

Five years ago at the blog -- the rise of secular evangelicals laid the foundation for the cult of Trump
THURSDAY, DECEMBER 1, 2016
Tom Hanks, creepy CGI Santa Clauses, and the theological canary in the coal mine
I've been making the point for a while now that the evangelical movement that I grew up with in the Bible Belt is radically different from the evangelical movement of today. I was aware that something was changing for a while, but the nature and the extent of the change crystallized for me when I read this 2004 article from Slate:
Next Stop, Bethlehem?
By David Sarno
The Polar Express is the tale of a boy's dreamlike train ride to the North Pole to meet Santa Claus. Like all stories worth knowing, it's rich enough in image and feeling to accommodate many interpretations. Chris Van Allsburg, the author of the book, calls his story a celebration of childhood wonder and imagination. William Broyles Jr., one of the screenwriters of this year's film version, calls it a kind of Odyssey in which a hero undertakes a mythic, perilous journey of self-discovery. And Paul Lauer, who is a key player in the film's marketing apparatus, sees The Polar Express as a parable for the importance of faith in Jesus Christ.
Lauer's firm, Motive Entertainment, is best known for coordinating the faith-based marketing of The Passion of the Christ. Motive helped spread early word of mouth about the filmby holding screenings for church groups and talking the movie up to religious leaders. When The Passion took in a stunning $370 million at the box office, making it the highest-grossing R-rated film in history, Lauer and his cohorts got a lot of the credit. Earlier this year, Motive was hired by Warner Bros. to promote The Polar Express to Christians. But wait, is The Polar Express an evangelical film?
You'd certainly think so, considering the expansive campaign of preview screenings, radio promotion, DVDs, and online resources that Lauer unfurled in the Christian media this fall. This Polar Express downloads page includes endorsements from pastors and links to church and parenting resources hosted by the Christian media outlet HomeWord. There are suggestions for faith-building activities and a family Bible-study guide that notes, for example, the Boy's Christ-like struggle to get the Girl a train ticket. "The Boy risked it all to recover the ticket," the guide observes. "Jesus gave His all to save us from the penalty of our sins."
HomeWord Radio, which claims to reach more than a million Christian parents daily, broadcast three shows promoting the film. At one point, the show's host wondered excitedly if the movie "might turn out to be one of the more effective witnessing tools in modern times." Motive also produced a promotional package that was syndicated to over 100 radio stations in which Christian recording artists like Amy Grant, Steven Curtis Chapman, and Avalon talked about the movie as they exited preview screenings.
…
Some audience members—and a few Christian film critics—would argue that Santa Claus isn't necessarily a stand-in for Jesus Christ. Last month, Lauer told the Mobile Register that he sees The Polar Express as a parable, "not a movie about belief in God." But when Lauer speaks to a Christian audience, he tells a different story. Lauer told HomeWord Radio that when he asked Robert Zemeckis about all the biblical parallels he was seeing in the film, the director "winked and said, 'Nothing in a movie this big ends up in the script by accident.' " (Zemeckis was traveling and wasn't available for comment.)
This is a spectacular example of getting the pertinent details of the story right and yet completely missing the point. In another piece, the understatement of “Santa Claus isn't necessarily a stand-in for Jesus Christ” would be sharply comic but Sarno seems to be completely oblivious to the joke.
I know we overuse the clip of the minister gunning down Santa in the middle of a children's sermon, but it illustrates an important point.
[ Clip missing -- Unfortunately, CBS/Viacom has decided that fair use rules only apply to little people.]
Over the past few years the evangelical movement has abandoned the majority of its most deeply held theological beliefs (think of how doctrinal differences with Catholics and, even more notably, Mormons have been put aside). It is not at all coincidental the beliefs that were abandoned were uniformly inconvenient from a political standpoint. The conservative movement has both weaponized and secularized the evangelical movement with remarkable success.
Traditionally, evangelicals were more concerned with the potential corruption of their own religion (frequently to the point of paranoia) than with what others were practicing. Christmas was a particularly hot-button issue. In the eyes of several good Southern Baptist ministers, the holiday had become unacceptably commercial, cultural rather than religious, and, in many ways, pagan. Most of the music, imagery, and traditions had nothing to do with the nativity, the "reason for the season." Often, this general hostility toward secular Christmas celebrations focused on Santa Claus.
Like many religious practices, the no-Santa rule could look a bit silly when viewed from the outside, but there's nothing unreasonable about adherents of a particular faith wanting to maintain what they see as the original meaning of a religious holiday. Growing up, I found these attitudes and the little lectures that often accompanied them painfully annoying, but, even though I disagreed, I could see where they were coming from from a theological standpoint.
Now, evangelicalism is a religious movement stripped of its religious elements. There is no scriptural foundation for tax cuts for the rich, deregulating greenhouse gases, or Donald Trump, but those are the defining issue of the movement of today.
Of course, evangelicals are not monolithic. There are many within the movement, some in positions of authority, who object to these obvious deviations from their original core principles. There are indications that the resistance is gaining momentum, and it is entirely possible that in a few years we will have to rethink our assumptions about evangelical Christians and politics. For now, though, this is a cultural (social reactionary) and political (far right) movement, not a religious one, and trying to think of it in any terms that these is misguided.
