Stormzy reveals Ed Sheeran collaboration as he announces new album
Stormzy has given the people what they want by announcing his second studio album, Heavy Is The Head.
After one heck of a successful year, including that showstopping Glastonbury performance, the 26-year-old is rounding up the decade with his next release.
Taking to Instagram, the rapper confirmed the news to his 2.6million followers, and it already looks iconic.
 (PRE ORDER LINK IN MY BIO).’
Right on cue, fans rushed to the comments section where they couldn’t control their excitement.
‘This will be proper,’ one wrote, while another added: ‘ITS COMING , A F**KING ALBUM NO WAY OH LORD.’
Someone else said: ‘I’m finna blast this s**t in DC. USA gotta get hip. Let’s go Stormz!’

Alongside the cover, Stormzy had also dropped the tracklisting, and there’s a number of collabs to get excited about.
As the second song on the list, titled Audacity, features Headie One, the star also revealed he’d worked with H.E.R on the upcoming hit One Second.
But it was number 11 that caught our eye, as Mr. Ed Sheeran’s name features alongside Burna Boy on the new track Own It.
It’s clear that 2019 has been Stormzy’s year seeing him make history at Glastonbury as well as land the cover of Time magazine.
Addressing his achievements, the star, whose real name is Michael Omari, wrote: ‘One of my absolute proudest moments. I can’t even comprehend this. I am on the cover of TIME.’
He continued: ‘I’ve stared at this cover for a few minutes and it feels like one of those “how the f***kkkk did man get here?!” moments.
‘God’s favour and the ever lasting love and support you guys show me has elevated me to a place in life where this South London kid is worthy enough to grace the cover of the most prestigious publication in the World.’
Thanking TIME and God for the ‘huge honour’ of being named a Next Generation Leader, the Vossi Bop rapper continued: ‘Anyone who knows me knows how much I shy away from being anything other than “Mike”.

‘The thought of being a “role model” or “leader” or whatever it is can often feel way way way too heavy and too overwhelming and a lot of the time […] I can’t even bare the weight of being myself let alone any of these other titles.’

11 Classification metrics
For regression problems, when the output is a whole number, we can use the sum of squares \(\text{RSS}\), the r-squared \(R^2\), the mean absolute error \(\text{MAE}\), and the likelihood. For classification problems we need to a new set of metrics.
A confusion matrix shows is a table that summarizes how the model classifies each group.
- No claims and predicted to not have claims - True Negatives (TN) = 1,489
- Had claims and predicted to have claims - True Positives (TP) = 59
- No claims but predicted to have claims - False Positives (FP) = 22
- Had claims but predicted not to - False Negatives (FN) = 489
confusionMatrix(test$pred_zero_one,factor(test$target))$table
## Reference
## Prediction 0 1
## 0 1489 489
## 1 22 59
These definitions allow us to measure performance on the different groups.
Precision answers the question “out of all of the positive predictions, what percentage were correct?”
\[\text{Precision} = \frac{\text{TP}}{\text{TP} + \text{FP}}\]
Recall answers the question “out of all of positive examples in the data set, what percentage were correct?”
\[\text{Recall} = \frac{\text{TP}}{\text{TP} + \text{FN}}\]
The choice of using precision vs. recall depends on the relative cost of making an FP or an FN error. If FP errors are expensive, then use precision; if FN errors are expensive, then use recall.
Example A: the model is trying to detect a deadly disease, which only 1 out of every 1,000 patients survives without early detection. Then the goal should be to optimize recall because we would want every patient that has the disease to get detected.
Example B: the model is detecting which emails are spam or not. If an important email is flagged as spam incorrectly, the cost is 5 hours of lost productivity. In this case, precision is the main concern.
In some cases, we can compare this “cost” in actual values. For example, if a federal court is predicting if a criminal will recommit or not, they can agree that “1 out of every 20 guilty individuals going free” in exchange for “90% of those who are guilty being convicted.”
A dollar amount can be used when money is involved: flagging non-spam as spam may cost $100, whereas missing a spam email may cost $2. Then the cost-weighted accuracy is
\[\text{Cost} = (100)(\text{FN}) + (2)(\text{FP})\]
The cutoff value can be tuned in order to find the minimum cost.
Fortunately, all of this is handled in a single function called confusionMatrix
.

11.1 Area Under the ROC Curve (AUC)
What if we look at both the true-positive rate (TPR) and false-positive rate (FPR) simultaneously? That is, for each value of the cutoff, we can calculate the TPR and TNR.
For example, say that we have 10 cutoff values, \(\{k_1, k_2, ..., k_{10}\}\). Then for each value of \(k\) we calculate both the true positive rates
\[\text{TPR} = \{\text{TPR}(k_1), \text{TPR}(k_2), .., \text{TPR}(k_{10})\} \]
and the true negative rates
\[\{\text{FNR} = \{\text{FNR}(k_1), \text{FNR}(k_2), .., \text{FNR}(k_{10})\}\]
Then we set x = TPR
and y = FNR
and graph x against y. The resulting plot is called the Receiver Operator Curve (ROC) and the the Area Under the Curve is called the AUC.
You can also think of AUC as being a probability. Unlike a conventional probability, this ranges between 0.5 and 1 instead of 0 and 1. In the Logit example, we were predicting whether or not an auto policy would file a claim. Then you can interpret the AUC as
The expected proportion of positives ranked before a uniformly drawn random negative
The probability that a model prediction for a policy that filed a claim is greater than the model prediction for a policy that did not file a claim
The expected true positive rate if the ranking is split just before a uniformly drawn random negative.
The expected proportion of negatives ranked after a uniformly drawn random positive.
The expected false positive rate if the ranking is split just after a uniformly drawn random positive.
You can save yourself time by memorizing these three scenarios:
\[ \text{AUC} = 1.0 \]
This is a perfect model that predicts the correct class for new data each time. It will have a ROC plot showing the curve approaching the top left corner so that the square area is 1.0.
\[ \text{AUC} = 0.5 \]*
When the ROC curve runs along the diagonal, then the area is 0.5. This performance is no better than randomly selecting the class for new data such that the proportions of each class match that of the data.
\[ \text{AUC} < 0.5 \] Any model having an AUC less than 0.5 means providing predictions that are worse than random selection, with a near 0 AUC indicating that the model makes the wrong classification almost every time. This can occur in two ways
The model is overfitting. For example, the AUC on the train data set may be higher than 0.8 but only 0.2 on the test data set. This indicates that you need to adjust the parameters of your model. See the chapter on the Bias-Variance Tradeoff.
There is an error in the AUC calculation or model prediction.
11.2 Example - Auto Claims
Let’s create an ROC curve and find the AUC for our logit.
library(pROC)
roc(test$target, preds, plot = T)
##
## Call:
## roc.default(response = test$target, predictor = preds, plot = T)
##
## Data: preds in 1511 controls (test$target 0) < 548 cases (test$target 1).
## Area under the curve: 0.7558
If we just randomly guess, the AUC would be 0.5, represented by the 45-degree line. A perfect model would maximize the curve to the upper-left corner.
The AUC of 0.76 is decent. If we had multiple models, we could compare them based on the AUC.
In general, AUC is preferred over Accuracy when there are many more “true” classes than “false” classes, which is known as having class imbalance. An example is bank fraud detection: 99.99% of bank transactions are “false” or “0” classes, and so optimizing for accuracy alone will result in a low sensitivity for detecting actual fraud.
11.3 Example: SOA HR, Task 5
The following question is from the Hospital Readmissions sample project from 2018.

"With the target variable being only 0 or 1, the binomial distribution is the only reasonable choice. Your assistant has done some research and learned that for the glm package in R, five link functions could be used with the binomial distribution. They are shown below (the inverse of the link function is presented here as it represents how the linear predictor is transformed into the actual response), where \(\nu\) is the linear predictor and \(\p\) is the response.
11.4 Example: SOA PA 12/12/19, Task 11
Already enrolled? Watch the full video: Practice Exams | Practice Exams + Lessons
Marketing has asked to demonstrate how your model is to be used with examples of cases that predict high value and cases that predict low value. Your assistant has prepared some sample cases that can be run through your model. You may need to adjust some of them to obtain illustrative examples of interest in marketing.
Write, in language appropriate for marketing, the illustration and demonstration they are looking for. This demonstration should be more detailed than what will go into your executive summary (including an example).
The sample cases are provided here and in your report template if you wish to include them in your report.
probability of each case. You need to create the column Prob of high using your GLM. Then you assign each case as being “High” or “Low” depending on if this value is above the cutoff.
The values that change are in bold.
| age | education num | marital status | occupation | cap_ga in | hours_per week | score | Prob of high | Value |
|---|---|---|---|---|---|---|---|---|
| 39 | 10 | Married-spouse | Group 3 | 0 | 40 | 60 | 0.32 | High |
| 39 | 10 | Never-married | Group 3 | 0 | 40 | 60 | 0.24 | Low |
| 39 | 5 | Married-spouse | Group 3 | 0 | 40 | 60 | 0.39 | High |
| 39 | 10 | Married-spouse | Group 5 | 0 | 40 | 60 | 0.80 | High |
| 39 | 10 | Married-spouse | Group 3 | 0 | 30 | 60 | 0.18 | Low |
You can interpret this as:
- The typical profitable customer is middle aged (39 years old), has 10 years of education, is married, and in group 3
- Having never been married decreases profitability
- Being less educated does not decreases profitability. You can see this because the customer with
education_num = 5
has the same characteristics as the first customer - Being in Group 5 increases profitability. You can see this because
Prob of high
increases to 0.8. - Working fewer than 40 hours per week decreases profitability
This was a difficult question. “Do not be afraid to be assertive and think creatively or to change the values that they give you,” the solution of SOA say.
Many candidates struggled with this task. Candidates needed to include sample cases that resulted in low and high-value predictions and clearly describe the analysis for the marketing team.
Candidates were encouraged to modify the supplied cases. Few elected to test changes in both directions from the base case.

Validation is performed as the user types by calling a validate() function. If the contents fail to pass validation, the control's invalid() method is invoked, which by default applies an "invalid" CSS class to the control.
The validation feedback is asymmetric, meaning that the text box will not reflect an invalid state until validation is enforced strictly. (By default, that happens when the focus leaves the control.) This allows the user to type without prematurely chastising them for entering invalid data. However, if the user corrects an invalid response, the invalid state is removed immediately after they type the character that fixes the data. In this way, the control is slow to complain, and quick to forgive. For more details on the motivation for asymmetric validation, see this user interface blog post .

java.lang.Object | +--javax.xml.parsers.SAXParser
Defines the API that wraps an XMLReader
implementation class. In JAXP 1.0, this class wrapped the
Parser
interface, however this interface was
replaced by the XMLReader
. For ease
of transition, this class continues to support the same name
and interface as well as supporting new methods.
An instance of this class can be obtained from the
SAXParserFactory.newSAXParser()
method.
Once an instance of this class is obtained, XML can be parsed from
a variety of input sources. These input sources are InputStreams,
Files, URLs, and SAX InputSources.
As the content is parsed by the underlying parser, methods of the
given HandlerBase
or the
DefaultHandler
are called.
Implementors of this class which wrap an underlying implementation
can consider using the ParserAdapter
class to initially adapt their SAX1 impelemntation to work under
this revised class.
An implementation of SAXParser
is NOT
guaranteed to behave as per the specification if it is used concurrently by
two or more threads. It is recommended to have one instance of the
SAXParser
per thread or it is upto the application to
make sure about the use of SAXParser
from more than one
thread.

Inheritance is most useful in modeling large, complex systems, which are well beyond the scope of any introductory book. One of the reasons that we are so fond of the character- picture example that we introduced in §5.8/91 is that such pictures lend themselves to an object-oriented solution, yet we can implement them in only a few hundred lines of code. We have used this example for many years, refining our code and simplifying the presentation. In reviewing the example for this book, we were able to remove nearly half the code by using the standard library and our generic handle class from Chapter 14.
In §5.8/91, we wrote several functions that represented a character picture as a
vector<string>
, a strategy that entailed copying characters whenever we constructed
a new picture. Copying all those characters wastes time and space. For example, if we
were to concatenate two copies of a picture, we would then store three copies of each
character: one for the original, and one for each side of the newly concatenated picture.
Even more important, the solution in §5.8/91 discards all structural information about the pictures. We have no idea how a given picture was formed. It might have been the initial input from our user, or it might have been created by applying one or more operations to simpler pictures. Some potentially useful operations require preserving a picture's structure. For example, if we want to be able to change the frame characters in a picture, we can do so only if we know which components of a picture were framed and which ones were not. We cannot look only for instances of the frame characters, because these characters might, coincidentally, have been part of an initial input picture.
As we'll see in this chapter, by using inheritance and our generic handle class, we will be able to preserve the structural information inherent in a picture, while at the same time reducing the space consumption of our system dramatically.

Lampard will not judge Chelsea on City performance
by BeSoccerChelsea arrive at Manchester City on a six-game winning streak but Frank Lampard admitted they will have to defend.
Frank Lampard will not judge his Chelsea players on one game as they prepare to face Manchester City, and admitted the Blues would need to defend well at the Etihad Stadium.
Chelsea go into their clash with the champions on Saturday having won six Premier League matches in a row and only Manchester United have beaten Lampard's men on the road this season, that defeat coming on the opening weekend back in August.
Since then Chelsea have lost only to league leaders Liverpool in the league, and City are still smarting from their 3-1 defeat to the Reds before the international break.
Lampard described City and Liverpool as having set the standard for his players to aspire to but said he would not be tearing up the gameplan that has been working well for him in recent weeks.
"We are playing Man City and I'm not going to judge us right now on that one game," Lampard told Soccer Saturday.
"I will judge us over what we've done until now, how we keep improving, how we work and where we go over a bigger period. We know that when you go to Man City or any of these big teams that you can lose, but what you must do is give everything and not roll over, no matter what happens, and you must fight until the end and give everything you can as a team.
"We won't change our plan hugely. Some people ask if we're going to go there and defend or can we go and attack but you're going to have to defend, it's all about how well you do it and it's going to be a huge part of the game."

Third-placed Chelsea are a point clear of City in the table and Lampard's men have been scoring freely, but the Blues have lost three of their last four Premier League away games against Pep Guardiola's men.
Lampard has a number of players in fine form, with Christian Pulisic having scored five goals in his last three league games, and the Chelsea boss said he feels no need to play down his players' achievements thus far.
"There's a balance to it for me and one thing is that we're playing well," said Lampard. "I don't want to hide that from the players and double bluff them - they are playing well and they should know that."
"But the other thing is, when you come up against these teams, you don't know if you're going to be judged at the end of the season on these games because there are 38 matches in a season and we want to win a huge majority of them.
"But you do know that when you come up against them head to head, the level of detail and the finer moments of the game will be the deciding factor."


Cocke Co. home bulldozed after complaints of drug, criminal activity
by WVLT NewsCOCKE COUNTY, Tenn (WVLT) -- Deputies with the Cocke County Sheriffs Office said a home was bulldozed after complaints repeated complaints of drug and criminal activity.
Officials met with Eric and Tammy Bryant who had concerns with a home on the 300 block of Epley road. The CCSO had conducted a complaint background at the home after deputies responded to various calls and made several arrests there over the years.
The Bryant family purchased the home and made the decision to bulldoze it.
CCSO officials said they are willing to work with property owners to clean up their communities.
"It is a joint effort between the community and the Sheriff's Office to clean up the streets and beautify the community," CCSO officials said.
Property owners that have experienced issues and would like to work with the Sheriff's Office to stop criminal activity are encouraged to call the office at<PHONE_NUMBER> and ask for Sheriff Armando Fontes and Chief Deputy Derrick Woods.

--- layout: archive title: Zulip Chat Archive permalink: /stream/113488-general/topic/string.20-.3E.20tactic.3F.html ---
Is there a good way to take a string (e.g. "simp, exact p") and return the tactic that executes it in interactive mode?
(I have some "self-describing tactics", which can print as a message "what they did" in terms of built-in tactics, and I would like to automatic verify they are producing correct output.)
I think the best I could do is something of type string -> parser (tactic unit)
I don't know how to run that in a tactic though ... unless we're parsing the parameters to the tactic. Is that good enough?
Unfortunately not. I'm deep inside a tactic by now.
I think we'd need to plead with the developers to give us a parser_state.mk
function
If I want to parse a rw_rule
, followed by a nat
(e.g. so I can write some_tactic foo 1
, or some_tactic ← foo 3
), what am I meant to do?
I've worked out that (q : parse (rw_rule_p (parser.pexpr 0)))
will parse a single rw_rule
.
Is the rw_rule
fed by the user through a begin ... end
block?
yes
I've decided that it's just as good to parse a list of rw_rules, and this seems to work out of the box.
(q : parse rw_rules) (n : ℕ)
Oh good then
I don't know if n : ℕ
will work but if it doesn't, you can use n : parse small_nat
Ah, I see, I just found parse small_nat
in conv
. Not bothering to use the parser for the nat seems okay.
Alright then :)
@Sebastian Ullrich knows the answer to this one. My first thought was either a parser A -> tactic A
lift, or the with_input
function which is used to implement format!
, but the first doesn't exist (you can make a parser from a tactic but not vice versa) and the second only works in the parser monad. There is no way to create a parser_state
in lean that I can see (which corresponds to creating a C++ parser
object), so I think parsing can only be done at parse time, not at tactic running time. (One suuper hacky way to maybe get this to work is to call lean
using the io
monad with a file that you create.)

You load MathJax into a web page by including its main JavaScript file into the page. That is done via a <script> tag that links to the MathJax.js file. Place the following line in the <head> section of your document:
<script type="text/javascript" src="path-to-MathJax/MathJax.js"></script>
where path-to-MathJax is replaced by the URL of the MathJax directory on your server, or (if you are using MathJax locally rather than through a server) the location of that directory on your hard disk. For example, if the MathJax directory is at the top level of your web server’s directory hierarchy, you might use
<script type="text/javascript" src="/MathJax/MathJax.js"></script>
to load MathJax.
Although it is possible to load MathJax from a site other than your own web server, there are issues involved in doing so that you need to take into consideration. See the Notes About Shared Servers for more details. Please do not link to the copy of MathJax at www.mathjax.org, as we do not have the resources to act as a web service for all the sites on the web that would like to display mathematics. If you are able to run MathJax from your own server, please do so (this will probably give you better response time in any case).
It is best to load MathJax in the document’s <head> block, but it is also possible to load MathJax into the <body> section, if needed. If you do this, load it as early as possible, as MathJax will begin to load its components as soon as it is included in the page, and that will help speed up the processing of the mathematics on your page. MathJax does expect there to be a <head> section to the document, however, so be sure there is one if you are loading MathJax in the <body>.
It is also possible to load MathJax dynamically after the page has been prepared, for example, via a GreaseMonkey script, or using a specially prepared bookmarklet. This is an advanced topic, however; see Loading MathJax Dynamically for more details.
There are several ways to configure MathJax, but the easiest is to use the config/MathJax.js file that comes with MathJax. See the comments in that file, or the configuration details section, for explanations of the meanings of the various configuration options. You can edit the config/MathJax.js file to change any of the settings that you want to customize. When you include MathJax in your page via
<script type="text/javascript" src="path-to-MathJax/MathJax.js"></script>
it will load config/MathJax.js automatically as one of its first actions.
Alternatively, you can configure MathJax efficiently by calling MathJax.Hub.Config() when you include MathJax in your page, as follows:
<script type="text/javascript" src="path-to-MathJax/MathJax.js">
MathJax.Hub.Config({
extensions: ["tex2jax.js"],
jax: ["input/TeX", "output/HTML-CSS"],
tex2jax: {
inlineMath: [ ['$','$'], ["\\(","\\)"] ],
displayMath: [ ['$$','$$'], ["\\[","\\]"] ],
},
"HTML-CSS": { availableFonts: ["TeX"] }
});
</script>
This example includes the tex2jax preprocessor and configures it to use both the standard TeX and LaTeX math delimiters. It uses the TeX input processor and the HTML-CSS output processor, and forces the HTML-CSS processor to use the TeX fonts rather that other locally installed fonts (e.g., STIX fonts). See the configuration options section (or the comments in the config/MathJax.js file) for more information about the configuration options that you can include in the MathJax.Hub.Config() call. Note that if you configure MathJax using this in-line approach, the config/MathJax.js file is not loaded.
Finally, if you would like to use several different configuration files (like config/MathJax.js, but with different settings in each one), you can copy config/MathJax.js to config/MathJax-2.js, or some other convenient name, and use
<script type="text/javascript" src="path-to-MathJax/MathJax.js">
MathJax.Hub.Config({ config: "MathJax-2.js" });
</script>
to load the alternative configuration file config/MathJax-2.js from the MathJax config directory. In this way, you can have as many distinct configuration files as you need.
The following examples show configurations that are useful for some common situations. This is certainly not an exhaustive list, and there are variations possible for any of them. Again, the comments in the config/MathJax.js file can help you decide what settings to include, even if you are using the in-line configuration method.
This example calls the tex2jax preprocessor to identify mathematics in the page by looking for TeX and LaTeX math delimiters. It uses $...$ and \(...\) for in-line mathematics, while $$...$$ and \[...\] mark displayed equations. Because dollar signs are used to mark mathematics, if you want to produce an actual dollar sign in your document, you must “escape” it using a slash: \$. This configuration also loads the AMSmath and AMSsymbols extensions so that the macros and environments they provide are defined for use on the page.
MathJax.Hub.Config({
extensions: ["tex2jax.js","TeX/AMSmath.js","TeX/AMSsymbols.js"],
jax: ["input/TeX","output/HTML-CSS"],
tex2jax: {
inlineMath: [['$','$'],["\\(","\\)"]],
processEscapes: true,
},
});
Other extensions that you may consider adding to the extensions array include: TeX/noErrors.js, which shows the original TeX code if an error occurs while processing the mathematics (rather than an error message), TeX/noUndefined.js, which shows undefined macros names in red (rather than producing an error), and TeX/autobold.js, which automatically inserts \boldsymbol{...} around your mathematics when it appears in a section of your page that is in bold. Most of the other TeX extensions are loaded automatically when needed, and so do not need to be included explicitly in your extensions array.
See the tex2jax configuration section for other configuration options for the tex2jax preprocessor, and the TeX input jax configuration section for options that control the TeX input processor.
This example calls the mml2jax preprocessor to identify mathematics in the page that is in MathML format, which uses <math display="block"> to indicate displayed equations, and <math display="inline"> or simply <math> to mark in-line formulas.
MathJax.Hub.Config({
extensions: ["mml2jax.js"],
jax: ["input/MathML","output/HTML-CSS"]
});
Note that this will work in HTML files, not just XHTML files (MathJax works with both), and that the web page need not be served with any special MIME-type. Also note that, unless you are using XHTML rather than HTML, you should not include a namespace prefix for your <math> tags; for example, you should not use <m:math> except in a file where you have tied the m namespace to the MathML DTD.
See the mml2jax configuration section for other configuration options for the mml2jax preprocessor, and the MathML input jax configuration section for options that control the MathML input processor.
This example provides for both TeX and MathML input in the same file. It calls on both the tex2jax and mml2jax preprocessors and the TeX and MathML input jax to do the job.
MathJax.Hub.Config({
extensions: ["tex2jax.js", "mml2jax.js"],
jax: ["input/TeX", "input/MathML", "output/HTML-CSS"],
});
Notice that no tex2jax configuration section is included, so it uses its default options (no single dollar signs for in-line math).
The majority of the code for the TeX and MathML input processors are not loaded until they are actually needed by the mathematics on the page, so if this configuration is used on a page that include only MathML, the TeX input processor will not be loaded. Thus it is reasonably efficient to specify both input processors even if only one (or neither one) is used.
This example configures MathJax to use the tex2jax preprocessor and TeX input processor, but the choice of output format is determined by MathJax depending on the capabilities of the user’s browser. The is performed by the MMLorHTML.js configuration file that is loaded in the config` array.
MathJax.Hub.Config({
config: ["MMLorHTML.js"],
extensions: ["tex2jax.js"],
jax: ["input/TeX"]
});
With this setup, Firefox or Internet Explorer with the MathPlayer plugin installed will use the NativeMML output processor, while all other browsers will use the HTML-CSS output processor. Since native MathML support is faster than MathJax’s HTML-CSS processor, this will mean that the web pages will display faster for Firefox and IE than they would otherwise. This speed comes at the cost, however, as you are now relying on the native MathML support to render the mathematics, and that is outside of MathJax’s control. There may be spacing or other display differences (compared to MathJax’s HTML-CSS output) when the NativeMML output processor is used.
See MathJax Output Formats for more information on the NativeMML and HTML-CSS output processors. See the MMLorHTML configuration section for details on the options that control the MMLorHTML configuration.
This example configures MathJax to look for MathML within your page, and to display it using the browser’s native MathML support, if possible, or its HTML-CSS output if not.
MathJax.Hub.Config({
config: ["MMLorHTML.js"],
extensions: ["mml2jax.js"],
jax: ["input/MathML"]
});
Using this configuration, MathJax finally makes MathML available in all modern browsers.
See the MMLorHTML configuration section for details on the options that control the MMLorHTML configuration file, the MathML configuration section for the options that control the MathML output processor, and the mml2jax configuration section for the options that control the mml2jax preprocessor.
The various components of MathJax, including its input and output processors, its preprocessors, its extensions, and the MathJax core, all can be configured through the config/MathJax.js file, or via a MathJax.Hub.Config() call (indeed, if you look closely, you will see that config/MathJax.js is itself one big call to MathJax.Hub.Config()). Anything that is in config/MathJax.js can be included in-line to configure MathJax.
The structure that you pass to MathJax.Hub.Config() is a JavaScript object that includes name-value pairs giving the names of parameters and their values, with pairs separated by commas. Be careful not to include a comma after the last value, however, as some browsers (namely Internet Explorer) will fail to process the configuration if you do.
The MathJax components, like the TeX input processor, have their own sections in the configuration object, labeled by the component name, and using an configuration object as its value. The object is itself a configuration object made up of name-value pairs that give the configuration options for the component.
For example,
MathJax.Hub.Config({
showProcessingMessages: false,
jax: ["input/TeX", "output/HTML-CSS"],
TeX: {
TagSide: "left",
Macros: {
RR: '{\\bf R}',
bold: ['{\\bf #1}',1]
}
}
});
is a configuration that includes two settings for the MathJax Hub (one for showProcessingMessages and one of the jax array), and a configuration object for the TeX input processor. The latter includes a setting for the TeX input processor’s TagSide option (to set tags on the left rather than the right) and a setting for Macros, which defines new TeX macros (in this case, two macros, one called \RR that produces a bold “R”, and one called \bold that puts is argument in bold face).
The config/MathJax.js file is another example that shows nearly all the configuration options for all of MathJax’s components.
The individual options are explained in the following sections, which are categorized by the component they affect.

NUnit is my Unit Testing tool of choice for .NET development. Microsoft provides a unit testing framework but it only works with some higher-end versions of Visual Studio. They're so similar that it's almost ridiculous that Microsoft created their own version. (See one of my previous posts for more information on Automating NUnit with MSBuild.) In the Java world it's fairly common to do Mocking to help make unit testing easier. I've written about using JMock for Unit Tesing in Java. In this post, I'd like to talk about a relatively new feature of NUnit which now supports Mocks out of the box.
Mock Objects are a technique that allow you to isolate classes from their dependencies for testing purposes. This isolation allows for fine-grained testing of single methods in a single class, possibly even before the dependent classes are fully implemented. This isolation allows your tests to run quickly and it makes testing small pieces of functionality much easier. When you've tested individual pieces of code in isolation you can have much higher confidence in larger-grained tests. This isolation becomes even more interesting when you are dealing with dependencies such as a data layer or a web service layer. External calls like that can be very time consuming or could fail if the remote system is down for maintenance.
One of the great things about using Mock Objects is that they force you to think about the dependencies that your classes and methods have. It forces you to think about the coupling between your classes. If you have high coupling then your code is often harder to test. If you have a loosely coupled design then testing and using Mock Objects is very much easier. Thinking about those design notions early can help you more easily manage change over time.
Maxims:
We're going to start with some simple code. We create a Domain object called Person and an interface for a Data Access object called IPersonRepository. Pretty simple at this point. {% highlight csharp %} public class Person { public string Id; public string FirstName; public string LastName; public Person(string newId, string fn, string ln) { Id = newId; FirstName = fn; LastName = ln; } } {% endhighlight %}
{% highlight csharp %}
public interface IPersonRepository
{
List
Next we create a PersonService object. This would represent all of the business logic in our application. It would interact with the Data Access tier and return information to the UI layer for display.
We wire together our objects using Constructor based Dependency Injection. All of the dependent Objects are sent in through the constructor. This allows for the loose coupling since the PersonService doesn't know about the Implementing class, but only the interface. Since it's done in the constructor we can also never have an invalid PersonService as would be the case if there was a setter for the IPersonRepository implementation.
This is again a fairly straightforward implementation, but I hope enough to display the issue at hand.
{% highlight csharp %}
public class PersonService
{
private IPersonRepository personRepos;
public PersonService(IPersonRepository repos)
{
personRepos = repos;
}
public List
Now we can start testing our PersonService. Notice that we haven't even implemented the IPersonRepository yet. That way we can make sure that everything in our PersonService class works as expected without having to think about other layers of the application.
{% highlight csharp %}
using System;
using System.Collections.Generic;
using NUnit.Framework;
using NUnit.Mocks;
[TestFixture]
public class PersonServiceTest
{
// The dynamic mock proxy that we will use to implement IPersonRepository
private DynamicMock personRepositoryMock;
// Set up some testing data
private Person onePerson = new Person("1", "Wendy", "Whiner");
private Person secondPerson = new Person("2", "Aaron", "Adams");
private List
The PersonService doesn't have a lot of logic in it, but I hope this illustrates how you easily can test various conditions using Mock objects. It also illustrates the idea of testing early by allowing you to test some code before all of the dependent objects are implemented.
While the Mocks built into NUnit might not be the most powerful or complete Mocking library out there, it should be sufficient for most uses. I'm sure they will continue to improve them over time as well, so I look forward to them becoming more powerful (and having better documentation) in the future.

Dear College Community,
Beginning Thursday, March 19th, the Library will reduce its hours to Monday-Friday, 9am-5pm. The Library will be open to all members of the CUNY community, but will be closed to the public. Anyone entering the building will need to use their ID at the turnstiles or show ID to use the accessibility gate. In order to limit large gatherings, only the first and second floors will be open to patrons. Each floor will be limited to 50 patrons who must abide by social distancing guidelines.
The Library will provide reference services virtually using our 24/7 chat service. Please use the link below to launch chat, send an email, or schedule a virtual consultation: https://library.csi.cuny.edu/help/ask
The Circulation/Reserves Desk will only be open to loan laptops and scientific calculators for the duration of the semester. Books from the general and reserve stacks will not circulate. We will be working to digitize textbooks in order to provide requested chapters via ILL/Document Delivery.

Magister Joan:
This Ivory Tower was nearly destroyed when the Elmoreden Empire fell. It survived not because of its power -- although the Ivory Tower had enough to control the continent -- but because its focus changed to become a pure research and educational institution.
Some other magisters argue that we should restore our old power, but personally I think we are better off this way.

Model accuracy is at 76%, which is a practical ratio without over fitting the model.
The Project Team compared 250 rows of Actual and Predicted DEFAULT results from the test data Credit_Data_Original.csv.
First, the model.predict_classes() function was used on the test data.
- encoded_predictions = default_model.predict_classes(X_test_scaled[:])
- prediction_labels = label_encoder.inverse_transform(encoded_predictions)
Then, Actual Outcomes and Variable Outcomes were printed for comparison.
- print(f"DEFAULT OUTCOME KEY: (DEFAULT YES: 1 , DEFAULt NO: 0 )")
- print(f"------------------------------------------------------")
- print(f"Predicted Outcome: {prediction_labels}")

Google Assistant now lets you create lists, search for podcasts and share photos
by Shereesa MoodleyGoogle on Friday added a range of new features to Google Assistant in an effort to simplify voice-enabled productivity.
“Starting to roll out today, you can use your Assistant to create and manage your notes and lists in Google Keep, Any.do, AnyList, or Bring! across Assistant-enabled phones and smart speakers,” the company said on its news blog.
Users can now enable support for third party list apps via the Assistant, where they can say things like “Hey Google, create a holiday gift list”. Additionally, users can use the Assistant to search for and listen to podcasts too.
“When you ask the Assistant for podcasts about a certain topic — ‘Hey Google, find a podcast about holiday cooking’ — it’ll suggest relevant episodes for you,” Google explained.
Meanwhile, users can also ask the Assistant to search for photos and share them directly by saying “Hey Google, look up photos from this weekend”.
According to Google, the new features are available on all Assistant-enabled phones.
In November, the company also released a news-reading Assistant feature in the United States.

SHALL WE DANCE?
A Film Review by Brian Takeshita
Rating: ***1/2 out of ****
The opening narration of SHALL WE DANCE? informs us that Japan is a nation of people who shy away from public or sometimes even private displays of emotion. Holding hands or saying "I love you" is a blatant and shameful deed. It is therefore that dancing, a pastime of holding hands, touching, and bodily expression is looked down upon with disdain. A regular man in the professional world should have no such desires.
So it is for Mr. Sugiyama. He is an accountant in his forties, married, and a father. What possible role could dance have in his life? However, one day, while traveling home on the train, he happens to notice a beautiful woman gazing from the window of a dance studio. He is captivated by her. Over the next few days he sees her repeatedly at the same time, gazing outward. One evening, he works up the courage to enter the studio and meet her. Instead of finding the woman of his dreams, he finds a wonderful new world, the world of dance.
When I approach foreign films, I never quite know what to expect. I suppose the stigma is that they are deep or aloof, and you may not be able to understand it all. Even though I've seen my share of foreign films, and know that this is not always the case, I was still stuck with this preconception going into SHALL WE DANCE?. Having seen PILLOW BOOK a few weeks previously probably didn't help. However, much like Mr. Sugiyama, what I found was something I didn't anticipate.
SHALL WE DANCE? is one of the funniest movies I have seen in quite some time. Not a lot of the humor is intelligent, and much of it is sheer physical comedy, but you quickly realize that as a viewer, you must give yourself to the feeling of the movie and not spend too much time analyzing it - much like dancing. Koji Yakusho, as Mr. Sugiyama, plays the straight man in this movie, but just watching his mannerisms and awkwardness in the dance studio is more than mildly amusing. His sincerity through otherwise strange situations reminded me a lot of Jimmy Stewart's earlier performances.
Although the plot of SHALL WE DANCE? follows a general formula from beginning to its inevitable ending, the plot does take a few twists along the way. For example, Mr. Sugiyama's wife, unaware of her husband's dance lessons, hires a private investigator to find out what he's been doing with his Wednesday nights. Rather than taking the wrong-conclusion-then-have-a-zany-confrontation route, this thread went in a surprising and decidedly more enjoyable direction.
Director Masayuki Suo presents the viewer with some excellent imagery, especially during musical interludes which feature classical, jazz, Latin, and pop music. One problem, however, is that at times too many things are happening on the screen at once. In long shots of the dance floor, I sometimes noticed several hilarious actions happening at the same time, but was not able to draw all of them in. Actually, I'm not sure I could label it a total drawback, as trying to see it all was a little fun.
At a hair under two hours, the film is well paced enough that the time seems to fly. Although the film finishes with a satisfactory finale, I had so thoroughly enjoyed the ride that I was sorry to see it end.

BY PROF. EDWIN JAHIEL
THE OPPOSITE OF SEX ** 2/3 .Written and directed by Don Roos. Photography, Hubert Taczanowski. Editing, David Codron. Production design, Michael Clausen. Costumes, Peter Mitchell. Music, Mason Daring. Producers, David Kirkpatrick, Michael Besman. Executive producers, Jim Lotti, Steve Danton, Cast: Christina Ricci (Dedee Truitt), Martin Donovan (Bill Truitt), Lisa Kudrow (Lucia), Lyle Lovett (Carl Tippett), Johnny Galecki (Jason), Ivan Sergei (Matt Mateo), William Scott Lee (Randy). A Sony Classics release. 100 minutes. Rated R. At the Art theater.

The film opens with a small bang. Dedee's stepfather is being buried. He may or may not have abused her as she later declares, but then Dedee has a lot of imagination. A teen nymphette-rebel-with-probable-cause, she paces around the graveside, smoking, and practically kicking the coffin into the hole. This must mean that she didn't like the man. She clearly does not like her life, her mother and perhaps herself. A troubled girl.
Post-burial she runs away --to what looks like a small Indiana town but is a suburb of South Bend--, to stay with her long-time-no-see much older half-brother Bill. He is a dedicated schoolteacher and seems to be a nice sort.  He also seems to have inherited the late Tom's sister Lucia. Rather nervous, insecure, sexually repressed, and apparently Bill's best friend, she's a protector of sorts who hovers around the man. Bill's current lover is a handsome, likable, twenty-something Mattt.
Dedee is 16, going at the same time on 30 and on 12. Like the combination brat, tramp and "agent provocateur" that she is, she sets out to take out her dysfunctionality on the Indiana Three. She thinks highly of herself as a philosopher-sociologist-shrink, and talks a lot, a big lot. In spasmodic ways, she also narrates the film. It's an old device but used here with much originality. Dedee comments to the audience about everything, acts like the eye of God, like someone who has already seen the finished movie The Opposite Sex, can tell us about it and about herself, pass judgments, tell us what we are expecting but won't get, tell us what she's going to tell us.
Dedee is a very fast talker. Her language is foul and trashy.  That kid is a mix of precocious wisdom and infantilism, lies and truths, skepticism and cynicism, particles of sophistication and big chunks of false sophistication.
She can be, and mostly is, unbearably irritating, but then that's part of the script's strategy. Her foul language would disqualify her from being a snake oil saleswoman, but she gets other kinds of results. The first major thing she does in Indiana is to come on blatantly to Matt, verbally and physically (but the audience is shown no nudity). In a flash she convinces Matt that he is, or can be a heterosexual, that in his affair with Bill "you are basically [verb deleted] your father." She seduces him pronto. The new couple takes off for California, and takes along ten thousand dollars stolen from Bill as well as the precious urn in which he kept Tom's ashes. Her seduction agenda. we learn later, is caused by Dedee's being pregnant by, most likely, one of her Louisiana lovers, teen-ager Randy, famous for having only one testicle.
This is just the beginning. If you want to pigeonhole the movie, is a sort of black comedy/farce. Outrageous complications follow in all directions, include flashbacks, home movies, everything and everybody.
There's local sheriff Carl played by the bizarre, improbable Lyle Lovett. He is a widower and sweet on Lucia. When the latter reproaches him "Your wife was dying and you [verb deleted] her nurse," Carl missing no beat replies "If Nancy didn't mind..." Bill gets blackmailed, then falsely defamed by his former student Jason. The town is most receptive to anti-gay feelings. and a scandal follows in the local media.
Bill and Lucia set out after Dedee-Matt who become Dedee-Randy when the latter materializes from the sticks of Louisiana. Carl follows Bill and Lucia. Add to this fights, guns firing, a motorcycle purchase, other madnesses and non sequiturs. Add to that an incredible trip to Canada as, by car, somehow (but how?) A follows B who follows C who has gone there with D, and where E magically pops up, and where the entire cast is reunited in a cabin in the woods!
The script overdoes its wish to be topical, current and trendy. Trying too hard to be original, it overloads the plot, overkills its gimmicks, characters, absurdism. Admittedly, there are moments of comedy and farce, but too many of them get drowned in much humor that thinks it is humor but is not. Instead of Marx Brothers crazy-funny absurdism, we get crazy-showy, uncensored absurdism, at full throttle. The would-be avant-garde continuity, including time and space, is a mess.
Is the film worth seeing? Yes, for specialized audiences that are into the off-beat. It 's an experiment whose originality is interesting, even if it is too smug, self-conscious, frenetic and patchy. Screenwriter and now first-time director Don Roos must know the tricks of Pirandello, Brecht and the French New Wave, but has gone overboard.
