Police shut down Jersey Shore house party thrown by YouTube stars
A small crowd initially gathered at the Broadwalk residence, but it swelled throughout the day to at least 1,500 people.
Several people were arrested Monday after hundreds flocked to Seaside Heights to see YouTube stars the Nelk Boys, who hosted a house party that violated the state’s coronavirus guidelines.
The Nelk Boys are Canadian-born Jesse Sebastiani, Kyle Forgeard and Steve Deleonardis. On Sept. 14, they rented the infamous “Jersey Shore” house (from the widely popular MTV reality series) to celebrate the launch of a new website selling merchandise for their Full Send brand, The Hill reports.
According to police, a small crowd initially gathered at the Broadwalk residence, but as it swelled throughout the day to at least 1,500 largely maskless people, police were forced to shut down the event.

“We will not tolerate this or these kinds of things that will disrupt an image we’re trying to correct,” Seaside Mayor Anthony Vaz told NBC on Tuesday. “It was shocking to me.”
He added, “When you have numbers of people like that in a community, that scares people. And we’re not going to tolerate it.”
The Nelk Boys posted videos on Instagram documenting the party, including the moment when police arrived. They were not among those arrested and charged during the party.
The trio, who have 5.7 million YouTube subscribers, gained Internet fame for their controversial pranks. Their followers also can’t get enough of the clips showing the massive, mask-free parties that the boys have been hosting at colleges across the country.
Their YouTube channel has been suspended for creating a “public health risk” with these college campus/house parties.
“We suspended the NELK channel from the Partner Program because they encouraged large numbers of people to disregard social distancing guidelines, creating a large public health risk,” the YouTube team said in a tweet.
The Nelk Boys previously protested coronavirus restrictions in Los Angeles by leading a crowd in a chant calling for gyms to reopen.

Tracee Ellis Ross signs overall deal with ABC Signature
‘I am thrilled to finally be sharing the news and expanding this part of my artistry at my home studio.’
Tracee Ellis Ross has inked an overall deal at ABC Signature, formerly ABC Studios, that will see her develop and produce content under her company, Joy Mill Entertainment.
The “Black-ish” star says she will “build stories, gather creatives and shape worlds” under the multi-year deal, via her company that will be housed at the Disney Television Studios, THR reports.
ABC Signature, which Ross calls “my home studio,” produces the “Black-ish” franchise, including “Grown-ish” (which airs on Freeform), “Mixed-ish,” and the recently announced “Old-ish,” which will center on Laurence Fishburne’s and Jenifer Lewis’ characters. Series creator Kenya Barris, who left ABC in 2018 for an eight-figure deal at the streaming giant Netflix, will pen its script, theGRIO previously reported.

“Mixed-ish,” a prequel to “Black-ish,” is set in the 1980s and explores the childhood of Tracee Ellis Ross’ biracial character, Rainbow. The show was recently granted a second season.
“I love sharing stories and using storytelling as a way to connect and celebrate humanity,” Ross said. “As an actor, I’ve had the joy of inhabiting nuanced and dynamic roles. As an executive producer, I am able to build stories, gather creatives and shape worlds as a way to illuminate different realities.”
Davis, president of ABC Signature, said of Ross’ new deal with the studio, “Tracee is a beloved member of the ABC Signature family and, as everyone knows, has brought so much to our -ish universe. We also love and admire Tracee’s passion for storytelling and developing projects, so we’re thrilled that Joy Mill Entertainment will be housed at our studio. We’re already incredibly excited by the projects she’s bringing to us in this new role.”
Former One Community and BET executive Adriana Ambriz has been tapped to serve as head of development at Joy Mill Entertainment, according to the report.
“This deal continues my journey as a storyteller and content creator,” Ross continued. “I am thrilled to finally be sharing the news and expanding this part of my artistry at my home studio, ABC Signature. Jonnie Davis, Tracy Underwood, and their team have been incredible collaborators, and I am eager to continue our shared journey.”
Black-ish is set to return to ABC for a seventh season with two election-themed specials.

Stumped by Bayes' Theorem? Try This Simple Workaround
Bayes' Theorem, which The Stanford Encyclopedia of Philosophy calls "...a simple mathematical formula" can be surprisingly difficult to actually solve. If you struggle with Bayesian logic, solving the "simple" formula involves not much more than guesswork. You have to translate a problem into "A given B" and "B given A", cross your fingers that you're guess for whatever A and B is is right, double check your thoughts, get thoroughly lost, and punch the resulting fractions into a calculator. The calculator will spit out an answer which may or may not be correct as you have no idea what your point-oh-something solution means in terms of the original problem. If this sounds like you, you're not alone: various studies have shown that the vast majority of physicians can't work the formula either.
But there's a more intuitive way to get to the same answer, without the counter-intuitive formula. The procedure in question? None other than the humble probability tree.
How to Use a Tree to Solve Bayes' Formula
This example problem is adapted from a problem in Gigrenzer & Hoffrage's How to Improve Bayesian Reasoning Without Instruction: Frequency Formats:
Out of 1,000 patients, 10 have a rare disease. Eight of those diseased individuals display symptoms. Out of the 990 healthy individuals, 95 display symptoms. What is the probability a patient with symptoms actually has the disease?
Here's the traditional textbook method, using the Bayesian algorithm.
If you're good with numbers, you may be able to immediately see that the answer this question with a simple ratio: number of diseased people with symptoms / total number of people with symptoms.
Now let's construct the same answer with a probability tree:
From there, the math is a simple ratio:
Number of people with disease and symptoms (8) / Total number with symptoms (8 + 95)
which gives us:
8 / 103 = 0.078.
Let's try another example (borrowed from Bayes' Theorem Problems):
You want to know a patient’s probability of having liver disease if they are an alcoholic. 10% of patients at a certain clinic have liver disease. Five percent of the clinic’s patients are alcoholics. Out of those patients diagnosed with liver disease, 7% are alcoholics.
Like the first problem, the first branch here is also "disease", but the second branch needs to address "alcoholism" instead of "symptoms". We're not told "how many" patients, so I'll use 1000--which is usually a sufficient number for problems like this. You're also not told explicitly the number of alcoholics (or % of non-liver disease alcoholics), but you can use a little logical deduction:
Out of 1000, patients, 5% (50 total) are alcoholic,
7% of patients with liver disease are alcoholic. That gives you 7 (green box), leaving 43 for the orange box.
Now all we have to do is figure out the ratio:
Number of people with disease and alcoholism (7) / Total number with alcoholism (50)
which gives us:
7 / 50 = 0.14
Which is exactly the same answer you would get by actually working the formula. In fact, I've never come across a Bayes' related problem that can't be answered with a probability tree and a little logical reasoning. So if the formula is giving you headaches, just do what I did--and ditch it in favor of a more intuitive approach.

LSU football coach on COVID-19: ‘Most of our players have caught it’
‘Three or four’ players have the virus and a few are currently in quarantine.
Louisiana State University football coach Ed Orgeron says a majority of the players contracted the coronavirus in the preseason.
Of the 115 athletes on the roster, Orgeron did not specify how many tested positive or when testing was conducted. He did confirm that “three or four” players have the virus and a few are in quarantine, The Hill reports.
“Not all of our players, but most of our players have caught it,” Orgeron said during his virtual press conference on Tuesday (Sept. 15), adding later that he did not know the percentage of players who contracted the virus.
“I think, hopefully, that once you catch it, you don’t get it again,” Orgeron added. “I’m not a doctor. I think they have that 90-day window, so most of the players that have caught it, we do feel like they’ll be eligible for games.
Read More: Ex-NFL star Derrius Guice accused of rape by 2 former LSU students
“So we look at the players that have caught it and say, ‘OK these guys should be eligible,’” Orgeron continued. “We look at the players who haven’t caught it; we talk to them about being very, very careful so they’re eligible for games. But we know that the players that haven’t caught it, we have to have some backups in their position ready in case they catch it. So we’re looking at our roster in that manner.”
Over the summer, 30 players were quarantined after a positive test or contact tracing, Sports Illustrated reported in June.
Orgeron said players who tested positive failed to practice social distancing, and many frequent the popular nightlife district for students known as Tigerland.
In June, the Louisiana Department of Health reportedly traced more than 100 positive COVID cases back to Tigerland.
“We need football. Football is the lifeblood of our country,” Orgeron said at a July roundtable with Vice President Pence.
“I don’t think we can take this away from our players, take this away from our state and our country,” he said.
The university overall has had 754 positive COVID-19 cases in the last month and 50 positives from Sept. 11 to Sept. 13, according to the report.

Swizz Beatz slammed for rejecting Missy Elliott and Janet Jackson Verzuz
Swizz says that Missy has done too much work with others for it to be a fair competition
The Verzuz series has easily been a highlight of 2020 but recently co-creator Swizz Beatz found himself in hot water after turning down a proposed battle between Missy Elliot and Janet Jackson.
Read More: With their Verzuz, Gladys Knight and Patti Labelle prove legends can still draw, and move, a crowd
For months Elliot fans have been championing her as the perfect musical legend to make the most of the social media-based series. But while discussing viable opponents for Elliot with Verzuz co-creator Timbaland, Swizz made it clear that Jackson simply wasn’t versatile enough to go toe-to-toe with her.
“Missy can be multiple people. Janet gonna just be Janet,” Swizz said, noting that Jackson might not have enough of a catalog if the two compared hits.
Not surprisingly, die-hard Jackson fans took issue with this stance with one noting, “Swizz Cheese Beatz needs to stop discrediting Janet Jackson…..this is the second time, he has tried to discredit her on IG live. He needs to stop discrediting Janet & focus on his family & his other child (with that UK British singer)!! Y’all not finna disrespect Janet!!”
Timbaland, who produced 90s classics with Elliot on artists like Aaliyah and Missy herself, didn’t agree with this assessment, saying “They are great friends, they love each other, the celebration is going to be great. Missy is going to want to celebrate with someone of her caliber that she knows is going to be a great celebration.”

Although the pushback was scathing, the producer stuck to his guns explaining that the match up just didn’t feel like a good fit to him.
“LETS BE CLEAR,” Swizz wrote in The Shade Room’s comment section. “I don’t think Missy & Janet is a good match up at all! Much love to Janet she’s ICON but I just didn’t feel that was a good match up. Janet got hits on hits but she should have a better person to celebrate with that’s all. Blessings….”

John Boyega quits perfume ambassdor role over Chinese ad exclusion
This isn’t the first time Boyega has called out China for racism
John Boyega says he will no longer serve as a global ambassador for the London-based perfume brand Jo Malone after the company decided to replace him in a commercial he created.
Read More: Jo Malone apologizes after John Boyega, Black families cut from China ad
According to ABC News the brand decided to replace Bodega for ads in the Chinese market with Chinese actor Liu Haoran. The brand recently released a statement apologizing and calling the replacement a misstep.
Via Twitter, Boyega said Jo Malone’s decision to, “replace my campaign in China by using my concepts and substituting a local brand ambassador for me, without either my consent or prior notice, was wrong.”
“The film celebrated my personal story — showcasing my hometown, including my friends and featuring my family,” wrote Boyega. “While many brands understandably use a variety of global and local ambassadors, dismissively trading out one’s culture this way is not something I can condone.”
The ad by the company owned by Estée Lauder was set to feature the actor in his hometown of London. “The London Gent,” as it was called featured Boyega riding a horse in his old neighborhood, hanging with his friends and spending time with his family, all dressed in traditional Nigerian garb.
In the original version, the actor is seen dancing and celebrating with friends but in the Chinese ad, all of the Black actors have been replaced with Chinese actors.
This not the first time Boyega has called out the Chinese market for being racist. His character Finn in Star Wars was visibly smaller in size on the Chinese poster in comparison to the American version.

The ad has since been removed and the company issued this statement, “We deeply apologize for what, on our end, was a mistake in the local execution of the John Boyega campaign.”

Lewis Hamilton says he ‘won’t let up’ after possible investigation into Breonna Taylor shirt
Lewis Hamilton stated he wanted to bring awareness to those who have been killed
Racing driver Lewis Hamilton is committed to using his platform to highlight injustices such as the Breonna Taylor case, and not even a pending investigation could stop him.
Sunday, Lewis – who is currently the only Black driver in Formula 1 – rocked a black T-shirt before and after a race that read “Arrest the cops who killed Breonna Taylor” on the front, along with a photo of Taylor on the back and the words “Say her name.”

Even though the Fédération Internationale de l’Automobile (which in English translates to the International Automobile Federation) considered launching a probe into his actions, the 35-year-old athlete not only won his race over the weekend, he also remains undeterred in his commitment to social justice.
“I’ve been wanting to bring awareness to the fact there are people being killed on the street, and someone was killed in her own house and they were in the wrong house and those guys are still walking free,” Hamilton said in a post-race press conference according to BBC News.

He also took to his social media feed to proudly post photos of himself wearing the T-shirt on Instagram, captioning the post: “It’s been 6 months since Breonna Taylor was murdered by policemen, in her own home. Still no justice has been served. We won’t stay silent. #JusticeForBreonnaTaylor.”
Tuesday, the FIA, which is a nonpolitical governing body for world motorsports, announced it had decided not to investigate whether Hamilton violated the organization’s rules by for wearing the shirt.
FIA also told CNN that it has decided to instead clarify its rules on political statements before the next race later this month.

Seaborn Version 0.11.0 is here with displot, histplot and ecdfplot
Seaborn Version 0.11 is Here
displot() for univariate and bivariate distributions
One of the big new changes is “Modernization of distribution functions” in Seaborn version 0.11. The new version of Seaborn has three new functions displot(), histplot() and ecdfplot() to make visualizing distributions easier. Yes, we don’t have to write your own function to make ECDF plot any more.
Seaborn’s displot() can be used for visualizing both univariate and bivariate distributions. Among these three new function, displot function gives a figure level interface to the common distribution plots in seaborn including histograms (histplot), density plots, empirical distributions (ecdfplot), and rug plots. For example, we can use displot() and create
We can also add rugplot() to show the actual values of the data to any of these plots.
Don’t get confused with distplot() for displot(). displot() is the new distplot() with better capabilities and distplot() is deprecated starting from this Seaborn version.
With the new displot() function in Seaborn, the plotting function hierarchy kind of of looks like this now covering most of the plotting capabilities.
Searborn Plotting Functions Hierarchy
In addition to catplot() for categorical variables and relplot() for relational plots, we now have displot() covering distributional plots.
Let us get started trying out some of the functionalities. We can install the latest version of Seaborn
pip install seaborn
Let us load seaborn and make sure we have Seaborn version 0.11.
import seaborn as sns print(sns.__version__) 0.11.0
We will use palmer penguin data set to illustrate some of the new functions and features of seaborn. Penguins data is readily available as part of seaborn and we can load using load_dataset() function.
penguins = sns.load_dataset("penguins")
penguins.head()
species island bill_length_mm bill_depth_mm flipper_length_mm body_mass_g sex
0 Adelie Torgersen 39.1 18.7 181.0 3750.0 Male
1 Adelie Torgersen 39.5 17.4 186.0 3800.0 Female
2 Adelie Torgersen 40.3 18.0 195.0 3250.0 Female
3 Adelie Torgersen NaN NaN NaN NaN NaN
4 Adelie Torgersen 36.7 19.3 193.0 3450.0 Female
We can create histograms with Seaborn’s histplot() function, KDE plot with kdeplot() function, and ECDF plot with ecdfplot(). However, we primarily use displot() to illustrate Seaborn’s new capabilities.
Histograms with Seaborn displot()
Let us make a simple histogram with Seaborn’s displot() function.
plt.figure(figsize=(10,8))
sns.displot(penguins,
x="body_mass_g",
bins=25)
plt.savefig("Seaborn_histogram_with_displot.png",
format='png',dpi=150)
Here we have also specified the number of bins in the histogram.
Seaborn histogram with displot()
We can also color the histogram by a variable and create overlapping histograms.
plt.figure(figsize=(10,8))
sns.displot(penguins,
x="body_mass_g",
hue="species",
bins=25)
plt.savefig("Seaborn_overlapping_histogram_hue_with_displot.png",
format='png',dpi=150)
In this example, we color penguins’ body mass by species.
Seaborn displot(): overlapping histograms using hue
Facetting with Seaborn displot()
With “col” argument we can create “small multiples” or faceting to create multiple plots of the same type using subsets of data based on a variable’s value.
plt.figure(figsize=(10,8))
sns.displot(penguins,
x="body_mass_g",
col="species",
bins=25)
plt.savefig("Seaborn_facetting_histogram_col_with_displot.png",
format='png',dpi=150)
Here, we have facetted by values of penguins’ species in our data set.
Seaborn displot(): facetting histogram using col
Density plot with Seaborn’s displot()
Let us use displot() and create density plot using kind=”kde” argument. Here we also color by species variable using “hue” argument.
plt.figure(figsize=(10,8))
sns.displot(penguins,
x="body_mass_g",
hue="species",
kind="kde")
plt.savefig("Seaborn_kernel_density_plot_with_displot.png",
format='png',dpi=150)
Seaborn displot(): kernel density plots
Check out the Seaborn documentation, the new version has a new ways to make density plots now.
ECDF Plot with Seaborn’s displot()
One of the personal highlights of Seaborn update is the availability of a function to make ECDF plot. ECDF aka Empirical Cumulative Distribution is a great alternate to visualize distributions.
In an ECDF plot, x-axis correspond to the range of data values for variables and on the y-axis we plot the proportion of data points (or counts) that are less than are equal to corresponding x-axis value.
Unlike histograms and density plot, ECDF plot enables to visualize the data directly without any smoothing parameters like number of bins. Its use possibly visible when you have multiple distributions to visualize.
A potential disadvantage is that
the relationship between the appearance of the plot and the basic properties of the distribution (such as its central tendency, variance, and the presence of any bimodality) may not be as intuitive.
Let us make ecdf plot using displot() using kind=”ecdf”. Here we make ecdf plot of a variable and color it based on values of another variable.
plt.figure(figsize=(10,8))
sns.displot(penguins,
x="body_mass_g",
hue="species",
kind="ecdf")
plt.savefig("Seaborn_ecdf_plot_with_displot.png",
format='png',dpi=150)
Seaborn displot(): Empirical Cumulative Density Function (ECDF) Plot
Bivariate KDE plot and Histogram with displot()
With kdeplot(), we can also make bivariate density plot. In this example, we use displot() with “kind=’kde'” to make bivariate density/ contour plot.
plt.figure(figsize=(10,8))
sns.displot(data=penguins,
x="body_mass_g",
y="bill_depth_mm",
kind="kde",
hue="species")
plt.savefig("Seaborn_displot_bivariate_kde_contour.png",
format='png',dpi=150)
Seaborn displot(): bivariate KDE Density plot
We can also make bivariate histogram with displot() using kind=”hist” option or histplot() to make density plot.
plt.figure(figsize=(10,8))
sns.displot(data=penguins,
x="body_mass_g",
y="bill_depth_mm",
kind="hist",
hue="species")
plt.savefig("Seaborn_displot_bivariate_hist.png",
format='png',dpi=150)
Seaborn displot() Bivariate histogram
New features to Seaborn jointplot()
With Seaborn 0.11, jointplot also has gained some nice features. Now jointplot() can take “hue” as argument to color data points by a variable.
sns.jointplot(data=penguins,
x="body_mass_g",
y="bill_depth_mm",
hue="species")
Seaborn jointplot color by variable using “hue”
And jointplot() also gets a way to plot bivariate histogram on the joint axes and univariate histograms on the marginal axes using kind=”hist” argument to jointplot().
sns.jointplot(data=penguins,
x="body_mass_g",
y="bill_depth_mm",
hue="species",
kind="hist")
Seaborn jointplot color by variable: bivariate histogram
Another big change that will help writing better code to make data visualization is that most Seaborn plotting functions, will now require their parameters to be specified using keyword arguments. Otherwise, you will see FutureWarning in v0.11.
As part of the update, Seaborn has also got spruced up documentation for Seaborn’s capabilities. Check out the new documentation on data structure that is accepted by Seaborn plotting functions. Some of the functions can take the data in both wide and long forms of data. Currently, the distribution and relational plotting functions can handle both and in future releases other Seaborn functions also will get the same data inputs.
