#query(longitude, latitude, [options], callback)
Query a vector tile by longitude and latitude and get an array of features in the vector tile that exist in relation to those coordinates.
A note on tolerance
: If you provide a positive value for tolerance you
are saying that you'd like features returned in the query results that might
not exactly intersect with a given lon/lat. The higher the tolerance the
slower the query will run because it will do more work by comparing your query
lon/lat against more potential features. However, this is an important parameter
because vector tile storage, by design, results in reduced precision of coordinates.
The amount of precision loss depends on the zoom level of a given vector tile
and how aggressively it was simplified during encoding. So if you want at
least one match - say the closest single feature to your query lon/lat - is is
not possible to know the smallest tolerance that will work without experimentation.
In general be prepared to provide a high tolerance (1-100) for low zoom levels
while you should be okay with a low tolerance (1-10) at higher zoom levels and
with vector tiles that are storing less simplified geometries. The units tolerance
should be expressed in depend on the coordinate system of the underlying data.
In the case of vector tiles this is spherical mercator so the units are meters.
For points any features will be returned that contain a point which is, by distance
in meters, not greater than the tolerance value. For lines any features will be
returned that have a segment which is, by distance in meters, not greater than
the tolerance value. For polygons tolerance is not supported which means that
your lon/lat must fall inside a feature's polygon otherwise that feature will
not be matched.

Returns
Object
:
The response has contains two main objects: hits
and features
.
The number of hits returned will correspond to the number of lon/lats queried and will
be returned in the order of the query. Each hit returns 1) a distance
and a 2) feature_id
.
The distance
is number of meters the queried lon/lat is from the object in the vector tile.
The feature_id
is the corresponding object in features object.
The values for the query is contained in the features object. Use attributes() to extract a value.
Example
vt.queryMany([[139.61, 37.17], [140.64, 38.1]], {tolerance: 0}, function(err, results) {
if (err) throw err;
console.log(results.hits); //
console.log(results.features); // array of feature objects
if (features.length) {
console.log(results.features[0].layer); // 'layer-name'
console.log(results.features[0].distance, features[0].x_hit, features[0].y_hit); // 0, 0, 0
}

If you think Univision’s Latin Grammys were muy caliente, you should have seen the end of the Cleveland Browns-Pittsburgh Steelers game on Fox.
NBC’s “Will and Grace” hit a new low in the adults 18-49 demographic with Thursday’s episode of the revival’s final season, which was pitted against Fox’s “Thursday Night Football” game between the Browns and Steelers. Cleveland’s 21-7 victory over Pittsburgh ended with multiple NFL players ejected after Browns defensive end Myles Garrett ripped the helmet off Steelers quarterback Mason Rudolph and hit him in the head with it, starting a big brawl that resulted in big Nielsen returns for Fox.
Fox was first in ratings with a 3.3 rating/16 share in the advertiser-coveted 18-49 demographic and in total viewers with an average of 11.7 million, according to preliminary numbers. Those numbers are the averages of Fox’s half-hour pregame show and then the Browns-Steelers “TNF” game, itself.

SLEEPY HOLLOW (director:Tim Burton; screenwriter: Andrew Kevin Walker/Kevin Yagher/based on the short story "The Legend of Sleepy Hollow" by Washington Irving; cinematographer: Emmanuel Lubezki; cast: Johnny Depp (Ichabod Crane), Christina Ricci (Katrina Van Tassel), Miranda Richardson (Lady Van Tassel/Crone), Michael Gambon (Baltus Van Tassel), Casper Van Dien (Brom Van Brunt ), Jeffrey Jones (Reverend Steenwyck), Christopher Walken (Headless Horseman), Richard Griffiths (Magistrate Philips), Christopher Lee (NYC Judge ), Marc Pickering (Young Masbeth), Michael Gough (Notary Hardenbrook), 1999)
Reviewed by Dennis Schwartz
A "Hollow-wood" production that couldn't be more hollow or Hollywood in style, and to its only benefit, is visually pleasing. It presents a classic mysterious aura about it through scenes of thick fog, horrid decapitations, and framed shots as if it was a period art picture coming off its frame and onto the screen. But the story, that's a different story; it is abominable. It is so ridiculous and incredulous that the filmmaker completely ruins Washington Irving's great short story. It is not the imaginative parable it was meant to be, but a story about a serial killer. So, you can forget the book, obviously Tim Burton did, that is if he ever read it. Here he throws away any imagination derived from the once (a very long time ago) popular book. In the late 1950s, the story's legend was common knowledge across most of America.
The film is not helped by a cast (I might add a rather talented cast of British and Americans) that are sleepwalking through their parts. The two stars, who have inane and unappealing and underwritten roles, and seem to be acting as if they have no idea of what they are saying or doing in this film, but seem to enjoy playing it up for the camera, while showing no chemistry for any romance to be deemed possible between them; which, without the two stars being credible performers, the film has little chance of succeeding.
This film has box office appeal as a date movie for the high school set, comforting each other as they snack on popcorn (which the theater owners will be largely appreciative of), and the teens, in all probability, will be reacting with bemused glee or mock horror to all the packets of ketchup unleashed during the Headless Horseman's romp through the Sleepy Hollow of 1799. Who else this movie should appeal to, is not for me to judge. But, when the audience leaves the theater, no harm is done, this is a totally forgettable film. There is no need to worry about nightmares over the gratuitous violence seen. This one is so obviously just a movie, that it can't even begin to match the book for its eloquence and the great manner of the book's very germane writing style, that is both lucid and thought provoking. If anything good can be said about this film, it would be that it brings back to the public's attention the forgotten writer Washington Irwing, someone who knew how to craft a ghost story back in the turn-of-the-19th-century and is still very readable. It's just too bad that a good movie couldn't result from such an accessible work.
It's best to forget about this movie as in any way connected with the novel, the only thing that seems to jive is the time period, the location, and the character called Ichabod Crane (Depp). But this time Crane is a constable, leaving NYC on orders from his superiors to hunt down a serial killer by using his innovative Sherlock Holmes-like logical detection methods, which are not appreciated by the local police authorities in NYC. So Crane is not the schoolteacher and choirmaster, as he was depicted in the book. From here on, the movie is off on its own tangent, playing havoc with the story. Katrina Van Tassel (Christina Ricci), the wealthy daughter of the local farmer, will be Crane's love interest, though she already has a suitor in the brave but chillingly jealous Brom Van Brunt (Casper Van Dien). In the book, the Headless Horseman is imaginary.  In the movie the Horseman is real, and the story becomes a vulgar mystery with some inept attempt to bring in an air of magical mystery to it, and it almost completely ignores the romantic rivalry between the two suitors, which was at the heart of Irving's story.
The town fathers, Reverend Steenwyck (Jones), Magistrate Philipse (Griffiths), Notary Hardenbrook (Gough), and including the now wealthiest resident of Sleepy Hollow, Baltus Van Tassel (Michael Gambon), the father of Katrina, married to her stepmother, Lady Van Tassel (Miranda). All the town fathers believe the previous 5 murders to be the work of a legendary Headless Horseman who haunts the area, but the skeptical Crane scoffs at this. It is only after he sees for himself that this is true that he decides there is a motive behind these serial murders, they are not random acts of violence.
 How a film could go so far afield, is not unusual for Hollywood, but in this case the film has gone too far afield from the story to even claim it is based on the book. Burton has made a story about a headless horseman who lives inside a tree trunk and is controlled by a twisted person who uses him to commit murders that will benefit their cause, but he has miserably failed to capture the imagination the story requires in its storytelling.
I would suggest reading the short story (about 40-pages) before or after seeing the film, and then see what you think of the film. I read the book after the film and am grateful that it called Washington Irving to my attention, again. Otherwise, I can't say enough bad things about the film's crass aim to take away the imagination of the story and replace it with not one shred of what Irving was after in his ghost story about romantic jealousy but here becoming a story about jejune classical horror images and a tacked on banal murder story. I'll admit, the movie looked good, better than most horror movies I might have raved about, but even with all the gory murders taking place and an excuse for a who-done-it movie evolving, a tedium set-in and the film seemed to lack suspense, breath and dimension; and, like a beautiful person without much else, what else can you say that is complimentary after you say, you look good!

SN college football rankings Week 13: Oklahoma comeback saves Sooners' Playoff hopes
by Zac Al-KhateebAnother week of college football has concluded, and it has provided us with perhaps the clearest picture yet of the eventual College Football Playoff.
That starts with Alabama, which entering Week 12 still looked to have an outside chance at making the Playoff. But a season-ending hip injury to quarterback Tua Tagovailoa, however, seems to have ended the Crimson Tide's hopes at a sixth straight Playoff berth, even after their win over Mississippi State.
MORE: Week 13 Playoff picture
Other significant games include losses by previously unbeaten teams Minnesota and Baylor, which lost to Iowa and Oklahoma, respectively. The chalk held in most other matchups, with undefeateds LSU, Ohio State and Clemson all winning; the same held true for one-loss teams in Georgia, Oregon, Utah and Penn State.
With that, SN's college football rankings ahead of the Week 13 slate of games:

Is Inequality Inevitable?
This page shows a model mentioned in Is Inequality Inevitable?. Quote:
If you simulate this economy, a variant of the yard sale model, you will get a remarkable result: after a large number of transactions, one agent ends up as an “oligarch” holding practically all the wealth of the economy, and the other 999 end up with virtually nothing. It does not matter how much wealth people started with. It does not matter that all the coin flips were absolutely fair.
Try to click "Run" a couple of times to observe wealth to concerntrate to a few people. You can find the source repo of the page here.

Finding Files¶
It’s a frequent problem that you want to be able to access files on different instruments, where the absolute path to the file might be in a different location. To get around this we define the exp_type (experiment type), which points to the location where a particular type of experiment is stored. The exp_type should have the following characteristics:
It should be unique (in a case-insensitive way)
It should be the name of the last one to three (separated by a forward slash) directories/folders where you have a particular type of experiment stored
The name of the folders referred to in exp_type should match on the server (google drive, ftp, etc) where the files are stored and on your local computer.
We provide the command XXXX. You supply this with a csv file containing two columns:
exp_type
file name
Of the files that you want. It will then run rclone to copy all those files to your local computer.
