THE TANGO LESSON A film review by Steve Rhodes Copyright 1997 Steve Rhodes
RATING (0 TO ****): **
There is a telling moment in THE TANGO LESSON. The spectacular dancer known as Pablo Veron, played with charisma by the extremely handsome, real life tango dancer of the same name, performs something akin to a solo whirlwind. He stops his spinning and admires himself in the floor-to-ceiling mirrors. After fixing a single strand of rebellious hair in his mustache, he stares into the mirror and blows a kiss to his true love, himself.
In a movie that mixes reality and fiction with a movie within a movie and with characters playing quasi-autobiographical parts, Sally Potter plays the lead named, you guessed it, Sally. Sally Potter, normally known as a writer and director, her last picture was ORLANDO, takes on both of these roles again in addition to starring in THE TANGO LESSON.
Late 40-ish Sally, with her pencil thin lips, her curly hair, and her attractive, svelte figure, makes an interesting contrast to Pablo and the male professional dancers in the film. Pablo especially is a younger hunk with rippling muscles, gobs of hair and a close cropped beard. Sally clearly enjoys every minute of it. Here the ambiguity is intentional for it is never clear where the fictional Sally ends and the real Sally begins.
So what exactly is a tango? Forget the concept of the tango as a part of the ballroom dance cannon for it shares little with the fox trot or the waltz. The tango is a dance in which two dancers become one from the knees up, but it is below the knees where the action lies. The feet fly around as if in constant but highly controlled spasms. The result is an energetic and highly visual endeavor. Would that the movie, THE TANGO LESSON, possessed more of that fire. When the dancers are on center stage the film certainly hums, but the rest of the film relies on a story that is so thin that it quickly loses its audience.
The story concerns an obsessive Sally, who finds a flaw in the flooring of her Parisian apartment. To fix it the contractor must tear up her apartment, so he asks her if she has some place to go for a few weeks. Boy, does she. Off to Buenos Aires, she signs up with a couple of instructors who teach tango via dance immersion. When she goes back to Paris to see her old instructor (Pablo), he is amazed at the transformation in his once awkward pupil.
Tango becomes the sexual subtext of the picture. To underscore this, Pablo greets Sally with a deep-voiced, "It's been a long time." With a twinkling smile, she responds, "It certainly has." To consummate their reunion they immediately "have tango" together.
Another subtheme concerns religion -- Sally and Pablo are both of Jewish ancestry. The passion of the tango has become their religion. "How did you choose the tango?" Sally asks Pablo. "I didn't; the tango chose me," he replies as if he had had a religious calling.
The movie contains little spoken dialog. The dialog is more danced than spoken. When the overly long film is in dance mode, the black-and-white images (only a small part of the film is in color) come alive. The surreal subplot of her pitching a movie to Hollywood and the remainder of the non-dancing parts are disappointing.
Sally does enjoy poking fun at Hollywood, especially the producer who wants to know why he should write her a check for $20,000,000 for her proposed film. The producer doesn't like it being in French and starring a legless fashion designer. That this film would almost certainly be a poor investment at twenty mil is ignored as Sally, the writer, ridicules Hollywood.
THE TANGO LESSON, even in the many slow parts, is a hard film not to like. You have to respect a director, writer and actor so in control of her life. "It doesn't suit me to follow," she tells Pablo. "It suits me to lead, and you can't deal with that."
THE TANGO LESSON runs 1:41. It is partially in French and Spanish with English subtitles, but it is mainly in the languages of English and dance. It is rated PG for adult themes. The picture would be fine for kids around ten and up.

A healthy breakfast doesn't need to taste boring - add zing to your morning with salsa and sweetcorn pancakes.
For the sweetcorn pancakes, sieve the flour and baking powder into a mixing bowl, then whisk in the egg and half of the milk to form a thick batter with a consistency slightly thicker than double cream. Add more milk as necessary to loosen the mixture. Season to taste with salt and freshly ground black pepper, then stir in the sweetcorn.
Heat the oil in a frying pan over a medium to high heat. Spoon half of the batter into the pan and fry for 1-2 minutes on each side, or until the pancake is golden-brown on both sides. Set the pancake aside on a warm plate and cover loosely with aluminium foil. Repeat with the remaining batter.
For the tomato chilli salsa, mix the tomatoes, coriander, chilli, sugar, finely chopped onion, lime juice and salt until well combined. Season to taste with freshly ground black pepper.
For the poached eggs, bring a pan of water to the boil, stir in the vinegar and turn down the heat so that the water is simmering. Add the eggs and poach for 3-4 minutes, or until cooked to your liking, then remove from the pan with a slotted spoon and drain on kitchen paper.
To serve, place one of the sweetcorn pancakes onto each plate, arrange two of the poached eggs on top, and finish with a spoonful of the tomato chilli salsa.

Results
Inhibition of cleavage increased with increasing extent of complementarity at 3' end
Inhibition increased with 12 or more bp complimentary
Competitors with 3' end mismatch adjacent to PAM inert to binding
Results(Contd.)
Mismatch within first 2 nucleotides, Cas9-RNA looses interrogation ability
Sequence homology adjacent to PAM is necessary for unwinding
DNA competitor containing mismatches within itself and with crRNA also resulted in perfect binding

- Discussion
A ssDNA cleaved twice slower than dsDNA, despite both having similar affinity to bind.
The Cas9-RNA recognizes 5'-NGG-3' PAM on non-target strand
ssDNA target strand is activated for cleavage in presence of an extended dsDNA across PAM.
The presence of 5'-NGG-3' PAM is critical

The Man in the Moon (1991) 99m.
A simple story well told. When stripped down, it all appears so basic that you begin to wonder why veteran directors Robert Mulligan and Mark Rydell took it upon themselves to make it (Rydell produced). I would guess that Mulligan knew well enough to trust his film to the right actors, if he could find them - and he did. THE MAN IN THE MOON will probably be best known now for the debut of Reese Witherspoon, who impresses in her role as Dani, a 14-year old girl living with her family in rural Louisiana during the 50s. A long-absent family friend moves in nearby, allowing 17-year old Court (Jason London, also making his debut ) to enter Dani's life. But it isn't just Dani: her older sister Maureen (Emily Warfield ) has noticed him too.
It works in the film's favor to have the story of a young girl's first crush presented in a basic manner. The story opens, progresses and closes, and even though significant events have unfolded it's hard to tell if the girls' lives will be changed that dramatically. This is what I like most about THE MAN IN THE MOON - it's like a chapter from a book, self-contained in its own simplicity. There are no complications, subplots, or clutter to distract us. It begins and ends with the girls on a front porch in the light of the full moon, suggesting that the story has completed its 'cycle' (everything takes place within a month). It also allows its characters leisure to breathe, walk, and talk so naturally that we don't focus on the acting. Witherspoon at first appears to be a teenybopper, then perhaps a 'wild child', but is perfectly at ease dressed either tomboyishly or in skirts. Sam Waterston, as the father of the girls, initially appears to be a traditionally strict father of the 50s, but reveals more elements to his character as the film progresses. Look at the nuances that slip through so effortlessly - for example, the priceless, dismissive look on Witherspoon's face when she first meets London outside her home. These are blink-and-you'll-miss-them moments, too ephemeral to be written into screenplays or catalogued in critiques. True, there are a few unsteady turns - the opening dialogue that explains the film's title (which really has very little to do with what follows), and some scenes that verge on melodrama - but they do not detract from the overall charm of the piece.
There's also another level that the film works on, and one which I believe is true of many features of the last decade that have showcased the talents of young, up-and-coming performers. As is the case with so many of her contemporaries, Witherspoon has graduated from the simple pleasures of her debut and moved on to harder, darker, and decidedly more adult material. It's a common occurrence: young stars don't want to be trapped in PG-features when they can stretch themselves as 'serious' actors. So while the nostalgia of THE MAN IN THE MOON isn't troweled on too thickly, the sight of a smart, ponytailed, wide-eyed Witherspoon automatically ensures that it will make itself an irretrievable memento. Given the film's subject matter of first love, lost love, and coming-of-age, this all conspires to make perfect sense.

Tutorial

Phaser.js
To play, just click on the game box


Zend\Crypt\BlockCipher implements the encrypt-then-authenticate mode using HMAC to provide authentication.
The symmetric cipher can be choose with a specific adapter that implements the Zend\Crypt\Symmetric\SymmetricInterface. We support the standard algorithms of the Mcrypt extension. The adapter that implements the Mcrypt is Zend\Crypt\Symmetric\Mcrypt.
In the following code we reported an example on how to use the BlockCipher class to encrypt-then-authenticate a string using the AES block cipher (with a key of 256 bit) and the HMAC algorithm (using the SHA-256 hash function).
1 2 3 4 5 6 | use Zend\Crypt\BlockCipher;
$blockCipher = BlockCipher::factory('mcrypt', array('algo' => 'aes'));
$blockCipher->setKey('encryption key');
$result = $blockCipher->encrypt('this is a secret message');
echo "Encrypted text: $result \n";
|
The BlockCipher is initialized using a factory method with the name of the cipher adapter to use (mcrypt) and the parameters to pass to the adapter (the AES algorithm). In order to encrypt a string we need to specify an encryption key and we used the setKey() method for that scope. The encryption is provided by the encrypt() method.
The output of the encryption is a string, encoded in Base64 (default), that contains the HMAC value, the IV vector, and the encrypted text. The encryption mode used is the CBC (with a random IV by default) and SHA256 as default hash algorithm of the HMAC. The Mcrypt adapter encrypts using the PKCS#7 padding mechanism by default. You can specify a different padding method using a special adapter for that (Zend\Crypt\Symmetric\Padding). The encryption and authentication keys used by the BlockCipher are generated with the PBKDF2 algorithm, used as key derivation function from the user’s key specified using the setKey() method.
Note
Key size
BlockCipher try to use always the longest size of the key for the specified cipher. For instance, for the AES algorithm it uses 256 bits and for the Blowfish algorithm it uses 448 bits.
You can change all the default settings passing the values to the factory parameters. For instance, if you want to use the Blowfish algorithm, with the CFB mode and the SHA512 hash function for HMAC you have to initialize the class as follow:
1 2 3 4 5 6 7 | use Zend\Crypt\BlockCipher;
$blockCipher = BlockCipher::factory('mcrypt', array(
'algo' => 'blowfish',
'mode' => 'cfb',
'hash' => 'sha512'
));
|
Note
Recommendation
If you are not familiar with symmetric encryption techniques we strongly suggest to use the default values of the BlockCipher class. The default values are: AES algorithm, CBC mode, HMAC with SHA256, PKCS#7 padding.
To decrypt a string we can use the decrypt() method. In order to successfully decrypt a string we have to configure the BlockCipher with the same parameters of the encryption.
We can also initialize the BlockCipher manually without use the factory method. We can inject the symmetric cipher adapter directly to the constructor of the BlockCipher class. For instance, we can rewrite the previous example as follow:
1 2 3 4 5 6 7 | use Zend\Crypt\BlockCipher;
use Zend\Crypt\Symmetric\Mcrypt;
$blockCipher = new BlockCipher(new Mcrypt(array('algo' => 'aes')));
$blockCipher->setKey('encryption key');
$result = $blockCipher->encrypt('this is a secret message');
echo "Encrypted text: $result \n";

#1 Nutrition & Calorie Tracking App
We believe — and medical studies prove — that the best way to lose weight and keep it off is to simply keep track of the foods you eat. Gimmicky machines and fad diets don't work, so we designed a free website that makes calorie counting and food tracking easy.


How will we achieve each of these beliefs:
Education For All
I will create a study sheet for everyone to study from. This study sheet will be able to found on this website.
Student's (and teacher's) Rights
Respect/Kindness
Equality
I will make sure that everyone is treated fairly, and treated the same no matter what gender, race, or ethnicity they are. If I see any injustices, I will speak out.
Dedication
I will work as long as needed to give you all the best education and school experience that you could have.
Peace in our class and peace with others
I will make sure that we have peace in our class, and that everyone is being respectful to one another. I also intend to set up peace treaties.
Fun Activites
I will make sure that we have fun activites that we can participate in. These will include fun games during class (but of course also educational, and relating to the topic).
Less Screen Time
I will do my best to reduce screentime by taking attendence for the teachers, creating a study sheet (read more about it under the "goals" section), and talking to teachers.
Good Foreign Relations
I will make sure that we will have good foreign relations with other countries and make sure that we have a relationship that beneifts both of us.
Extra Credit
I will give extra credit according by the Constitution's rules. With that, I will also give 3-5 pieces of homework per month, because right now, we don't have a long of homework to give extra credit on.


Appearance
Joy has a very attractive appearance: pink hair and blue eyes. All Joy has a pink dress and a white apron and a cap with a red cross.

Pharms - Phentermine |
(pill / tablet) |
This is an account of the recreational use of Phentermine, which is supposedly similar to Amphetamines. The pills are 30mg. For this experience I am only taking 1 pill to see how my body reacts. Note: I have only had one experience with Methamphetamine and I was drunk at the time so I do not remember the feelings other than I could not go to sleep. Therefore, I have no real experience with stimulants to compare this to.
11am – Have the day off so I decided to try Phentermine which my parent uses for weight loss. Decided to eat pizza first because the drug causes a loss in appetite.
12pm – Took one dose of Phentermine 30mg orally.
1pm - Not really feeling Euphoric, just a little “speedy” as I started to clean my room.
1:30pm – Starting to feel a *very* mild sense of euphoria, a little mood uplift. Still cleaning room, it feels good when I clean.
2pm - No Change – room is cleaned.
3:30pm – Just played my guitar for an hour and a half still feeling the same, I have a feeling either this stuff is time released or that this is the “peak”. I am going to exercise now.
4:00pm – Finished exercising, it felt great. I can’t tell if lack of fatigue was due to the Phentermine or just my muscles becoming more efficient. I still don’t notice much of a difference in mood. I am now going to study to see if I can concentrate better.
11:00pm – Studying was a lot easier, my mind was able to absorb the information easier and I was able to concentrate better. Didn’t have an appetite (guess the pills work) but ate dinner anyway. I’m not tired but I need to force myself to go to bed.
All in all, it was an interesting experience. I’m sure I had increased energy throughout the day not much euphoria but it would be interesting to increase the dosage to see if it brought about euphoric effects.

The juneau-marshall
and juneau-marshall-rdf
modules provides memory-efficient typed and untyped POJO serializing and parsing for a variety of languages.
// A simple bean
public class Person {
public String name = "John Smith";
public int age = 21;
}
// Produces:
// "{"name":"John Smith","age":21}"
String json = Json.of(new Person());
// Parse back into a bean.
Person person = Json.to(json, Person.class);
// Various other languages.
String json5 = Json5.of(person);
String xml = Xml.of(person);
String html = Html.of(person);
String urlEncoding = UrlEncoding.of(person);
String uon = Uon.of(person);
String openApi = OpenApi.of(person);
String rdfXml = RdfXml.of(person);
String rdfXmlAbbriev = RdfXmlAbbrev.of(person);
String n3 = N3.of(person);
String nTriple = NTriple.of(person);
String turtle = Turtle.of(person);
String plainText = PlainText.of(person);
String csv = Csv.of(person);
byte[] msgPack = MsgPack.of(person);
The juneau-rest-server
and juneau-rest-client libraries
provide server and client side REST capabilities that can be used by themselves, or together to create
simplified yet sophisticated Java-based REST communications layers that completely hide away the complexities
of the REST protocol from end-users.
// Server-side endpoint
@Rest(path="/petstore")
public class PetStoreRest extends BasicRestServlet implements BasicUniversalConfig {
@RestPost(path="/pets", guards=AdminGuard.class)
public Ok addPet(
@Content CreatePet createPetBean,
@Header("E-Tag") UUID etag,
@Query("debug") boolean debug
) throws BadRequest, Unauthorized, InternalServerError {
// Process request here.
return Ok.OK; // Standard 400-OK response.
}
}
// Client-side Java interface that describes the REST endpoint
@Remote(path="/petstore")
public interface PetStoreClient {
@RemotePost("/pets")
Ok addPet(
@Content CreatePet createPet,
@Header("E-Tag") UUID etag,
@Query("debug") boolean debug
) throws BadRequest, Unauthorized, InternalServerError;
}
// Use a RestClient with default JSON 5 support and BASIC auth.
RestClient client = RestClient.create().json5().basicAuth(...).build();
// Instantiate our proxy interface.
PetStoreClient store = client.getRemote(PetStoreClient.class, "http://localhost:10000");
// Use it to create a pet.
CreatePet createPet = new CreatePet("Fluffy", 9.99);
Pet pet = store.addPet(createPet, UUID.randomUUID(), true);
The juneau-dto module
contains several predefined POJOs for generating commonly-used document types that
are designed to be used with the Juneau Marshaller APIs for both serializing and parsing.
For example, you can build HTML DOMs in Java.
import static org.apache.juneau.dto.html5.HtmlBuilder.*;
// An HTML table
Object mytable =
table(
tr(
th("c1"),
th("c2")
),
tr(
td("v1"),
td("v2")
)
);
String html = Html.of(mytable);

c1
c2

v1
v2

The juneau-config
module contains a powerful API for creating and using INI-style config files.
# A set of entries
[Section1]
# An integer
key1 = 1
# A boolean
key2 = true
# An array
key3 = 1,2,3
# A POJO
key4 = http://bar
// Create a Config object
Config config = Config.create().name("MyConfig.cfg").build();
// Read values from section #1
int key1 = config.getInt("Section1/key1");
boolean key2 = config.getBoolean("Section1/key2");
int[] key3 = config.getObject("Section1/key3", int[].class);
URL key4 = config.getObject("Section1/key4", URL.class);
The juneau-assertions
module in Juneau is a powerful API for performing fluent style assertions.
import static org.apache.juneau.assertions.Assertions.*;
// Check the contents of a string.
// "as" methods perform a transformation.
// "is" methods perform an assertion.
assertString("foo, bar")
.asSplit(",")
.asTrimmed()
.is("foo", "bar");
// Extract a subset of properties from a list of beans and compare using Simplified JSON.
List<MyBean> myListOfBeans = ...;
assertBeanList(myListOfBeans)
.asPropertyMaps("a,b")
.asJson().is("[{a:1,b:'foo'}]");
The juneau-rest-springboot
modules provides servlets for quickly and seemlessly deploying REST endpoints in a Spring Boot application. Has built-in support for
auto-generated Swagger documentation and call statistics on all endpoints.
@SpringBootApplication
@Controller
public class App {
//Entry point method.
public static void main(String[] args) {
new SpringApplicationBuilder(App.class).run(args);
}
// Our root REST bean.
// Note that this must extend from SpringRestServlet to allow use of injection.
// All REST objects are attached to this bean using the Rest.children() annotation.
@Bean
public RootResources getRootResources() {
return new RootResources();
}
// Registers our REST bean at the URI root.
@Bean
public ServletRegistrationBean<Servlet> getRootServlet(RootResources rootResources) {
return new ServletRegistrationBean<>(rootResources, "/*");
}
// Injected child resource.
@Bean
public HelloWorldResource getHelloWorldResource() {
return new HelloWorldResource();
}
// Injected child bean used in injected child resource.
@Bean
public HelloWorldMessageProvider getHelloWorldMessageProvider() {
return new HelloWorldMessageProvider("Hello Spring injection user!");
}
}
Our root resource servlet serves as a router page. It is defined as follows:
@Rest(
title="Root resources",
description="Example of a router resource page.",
children={
HelloWorldResource.class,
}
)
@HtmlDocConfig(
widgets={
ContentTypeMenuItem.class
},
navlinks={
"api: servlet:/api",
"stats: servlet:/stats",
"$W{ContentTypeMenuItem}",
"source: $C{Source/gitHub}/org/apache/juneau/examples/rest/$R{servletClassSimple}.java"
},
aside={
"
",
"
This is an example of a 'router' page that serves as a jumping-off point to child resources.
",
"
Resources can be nested arbitrarily deep through router pages.
",
"
Note the API link provided that lets you see the generated swagger doc for this page.
",
"
Also note the STATS link that provides basic usage statistics.
",
"
Also note the SOURCE link on these pages to view the source code for the page.
",
"
All content on pages in the UI are serialized POJOs. In this case, it's a serialized array of beans with 2 properties, 'name' and 'description'.
",
"
Other features (such as this aside) are added through annotations.
",
"
"
},
asideFloat="RIGHT"
)
public class RootResources extends BasicSpringRestServletGroup implements BasicUniversalConfig {
// No code!
}
The HelloWorldResource class shows an example of a child resource
defined as an injected bean.
@Rest(
title="Hello World",
description="An example of the simplest-possible resource",
path="/helloWorld"
)
@HtmlDocConfig(
aside={
"
",
"
This page shows a resource that simply response with a 'Hello world!' message
",
"
The POJO serialized is a simple String.
",
"
"
}
)
public class HelloWorldResource extends BasicRestObject implements BasicUniversalConfig {
@Inject
private HelloWorldMessageProvider messageProvider;
@RestGet(path="/*", summary="Responds with injected message")
public String sayHello() {
return messageProvider.get();
}
}
Other features:
-
Fast memory-efficient serialization.
-
Fast, safe, memory-efficient parsing. Parsers are not susceptible to deserialization attacks.
-
KISS is our mantra! No auto-wiring. No code generation. No dependency injection. Just add it to your classpath and use it. Extremely simple unit testing!
-
Enjoyable to use
-
Tiny - ~1MB
-
Exhaustively tested
-
Lots of up-to-date documentation and examples
-
Minimal module dependencies making them optimal for uber-jars
-
Built on top of Servlet and Apache HttpClient APIs that allow you to use the newest HTTP/2 features
such as request/response multiplexing and server push.


Wait for all the given futures to complete and collect their values.
Returns a future which will complete once all the futures in a list are complete. If any of the futures in the list completes with an error, the resulting future also completes with an error. Otherwise the value of the returned future will be a list of all the values that were produced.
If eagerError
is true, the future completes with an error immediately on
the first error from one of the futures. Otherwise all futures must
complete before the returned future is completed (still with the first
error to occur, the remaining errors are silently dropped).
If cleanUp
is provided, in the case of an error, any non-null result of
a successful future is passed to cleanUp
, which can then release any
resources that the successful operation allocated.
The call to cleanUp
should not throw. If it does, the error will be an
uncaught asynchronous error.

Set to null on error. int remaining = 0; // How many futures are we waiting for. var error; // The first error from a future. StackTrace stackTrace; // The stackTrace that came with the error. // Handle an error from any of the futures. void handleError(theError, theStackTrace) { remaining--; if (values != null) { if (cleanUp != null) { for (var value in values) { if (value != null) { // Ensure errors from cleanUp are uncaught. new Future.sync(() { cleanUp(value); }); } } } values = null; if (remaining == 0 || eagerError) { result._completeError(theError, theStackTrace); } else { error = theError; stackTrace = theStackTrace; } } else if (remaining == 0 && !eagerError) { result._completeError(error, stackTrace); } } try { // As each future completes, put its value into the corresponding // position in the list of values. for (Future future in futures) { int pos = remaining; future.then((Object/*=T*/ value) { remaining--; if (values != null) { values[pos] = value; if (remaining == 0) { result._completeWithValue(values); } } else { if (cleanUp != null && value != null) { // Ensure errors from cleanUp are uncaught. new Future.sync(() { cleanUp(value); }); } if (remaining == 0 && !eagerError) { result._completeError(error, stackTrace); } } }, onError: handleError); // Increment the 'remaining' after the call to 'then'. // If that call throws, we don't expect any future callback from // the future, and we also don't increment remaining. remaining++; } if (remaining == 0) { return new Future.value(const []); } values = new List/*<T>*/(remaining); } catch (e, st) { // The error must have been thrown while iterating over the futures // list, or while installing a callback handler on the future. if (remaining == 0 || eagerError) { // Throw a new Future.error. // Don't just call `result._completeError` since that would propagate // the error too eagerly, not giving the callers time to install // error handlers. // Also, don't use `_asyncCompleteError` since that one doesn't give // zones the chance to intercept the error. return new Future.error(e, st); } else { // Don't allocate a list for values, thus indicating that there was an // error. // Set error to the caught exception. error = e; stackTrace = st; } } return result; }

Who Am I
My Background
Hi there! My name is Tao. I come from China, though I spent my primary school years growing up in the UK, so you could say that I’m bilingual. I graduated with an Economics degree from Cambridge, and I’m currently pursuing my passion for finance at London Business School, studying Masters in Financial Analysis. I hope you can get to know more about me from this website!
Extra-curricular Activities
Bridges for Enterprise
At Cambridge, I participated in a society called Bridges for Enterprise.  I was the Finance Advisor in the group.
We worked on many interesting projects. One was with a Microfinance firm in Kenya. Their mission was to provide lending to talented individuals who had no access to finance, or had no credit history, and to help them achieve their goals of starting businesses. As advisors, we helped them solve the problem of high default rates through more sophisticated ways of lending, and also helped them to raise capital through constructing a skeleton pitch deck. It was really rewarding to see our client transform.
Business Negotiations Society
This was a society where we would represent the management team of a particular business, and debate and negotiate with teams from other schools on various terms and contracts and press for the interest of our firm.
I was a leader in my team for various competitions. One of them was a discussion on the import of iron ore from Southeast Asia. We, as the receiver, have to negotiate as to how we inspect quality, the pricing of iron ores of different qualities, the payment method and the compensation schemes. This experience was really interesting as it allowed me to learn about a completely new industry, and to research how contracts in this industry works. Not only so, I’ve learnt to communicate efficiently, delegate and supervise tasks and also how to collaborate and play to each other’s strengths.
My Hobbies
I love playing badminton and pool with friends, and I also participated in the Cambridge Pool Competition. My intellectual curiosity has led me to self-studying Japanese as a third language, and I’m currently studying the programming language R as well. I’m also “self-employed” as a home bartender, and I sometimes try to think outside the box and explore my own cocktail recipes (definitely not a drinker I promise, but a rather interesting field of knowledge I like to explore in my own time).

Tools for Reasoning about Web Page Layouts
Cassius has led to several published academic papers.
Automated verification can ensure that a web page satisfies accessibility, usability, and design properties regardless of the end user's device, preferences, and assistive technologies. However, state-of-the-art verification tools for layout properties do not scale to large pages because they rely on whole-page analyses and must reason about the entire page using the complex semantics of the browser layout algorithm.
This paper introduces and formalizes modular layout proofs. A modular layout proof splits a monolithic verification problem into smaller verification problems, one for each component of a web page. Each component specification can use rely/guarantee-style preconditions to make it verifiable independently of the rest of the page and enabling reuse across multiple pages. Modular layout proofs scale verification to pages an order of magnitude larger than those supported by previous approaches.
We prototyped these techniques in a new proof assistant, Troika. In Troika, a proof author partitions a page into components and writes specifications for them. Troika then verifies the specifications, and uses those specifications to verify whole-page properties. Troika also enables the proof author to verify different component specifications with different verification tools, leveraging the strengths of each. In a case study, we use Troika to verify a large web page and demonstrate a speed-up of 13--1469x over existing tools, taking verification time from hours to seconds. We develop a systematic approach to writing Troika proofs and demonstrate it on 8 proofs of properties from prior work to show that modular layout proofs are short, easy to write, and provide benefits over existing tools.
The paper explains Troika, a proof assistant built atop VizAssert, which allows verifying web pages piece-by-piece. The paper is available in PDF format.
Usability and accessibility guidelines aim to make graphical user interfaces accessible to all users, by, say, requiring that text is sufficiently large, interactive controls are visible, and heading size corresponds to importance. These guidelines must hold on the infinitely many possible renderings of a web page generated by differing screen sizes, fonts, and other user preferences. Today, these guidelines are tested by manual inspection of a few renderings, because 1) the guidelines are not expressed in a formal language, 2) the semantics of browser rendering are not well understood, and 3) no tools exist to check all possible renderings of a web page. VizAssert solves these problems. First, it introduces visual logic to precisely specify accessibility properties. Second, it formalizes a large fragment of the browser rendering algorithm using novel finitization reductions. Third, it provides a sound, automated tool for verifying assertions in visual logic.
We encoded 14 assertions drawn from best-practice accessibility and mobile-usability guidelines in visual logic. VizAssert checked them on on 62 professionally designed web pages. It found 64 distinct errors in the web pages, while reporting only 13 false positive warnings.
The paper explains how VizAssert works, including the formalizations of line height, margin collapsing, and floating boxes, and the verification tool built atop it. The paper is available in PDF format.
Web pages define their appearance using Cascading Style Sheets, a modular language for layout of tree-structured documents. In principle, using CSS is easy: the developer specifies declarative constraints on the layout of an HTML document (such as the positioning of nodes in the HTML tree), and the browser solves the constraints to produce a box-based rendering of that document. In practice, however, the subtleties of CSS semantics make it difficult to develop stylesheets that produce the intended layout across different user preferences and browser settings.
This paper presents the first mechanized formalization of a substantial fragment of the CSS semantics. This formalization is equipped with an efficient reduction to the theory of quantifier-free linear real arithmetic, enabling effective automated reasoning about CSS stylesheets and their behavior. We implement this reduction in Cassius, a solver-aided framework for building semantics-aware tools for CSS. To demonstrate the utility of Cassius, we prototype new tools for automated verification, debugging, and synthesis of CSS code. We show that these tools work on fragments of real-world websites, and that Cassius is a practical first step toward solver-aided programming for the web.
The paper explains how Cassius works, the main limitations that make its efficient translation to SMT possible, and the various tools that can be built atop it. The paper is available in PDF format.
Web design is a visual art, but web designs are code. Designers work visually and must then manually translate their designs to code. We propose using synthesis to automatically translate the storyboards designers already produce into CSS stylesheets and JavaScript code. To build a synthesis tool for this complex domain, we will use a novel composition mechanism that allows splitting the synthesis task among domain-specific solvers.
We have built a domain-specific solver for CSS stylesheets; solvers for DOM actions and JavaScript code can be built with similar techniques. To compose the three domain-specific solvers, we propose using partial counterexamples to exchange information between different domains. Early results suggest that this composition mechanism is fast and allows specializing each solver to its domain.
The paper explains the larger plans for building upon the OOPSLA’16 work to create a synthesizer for interactive web pages. The paper is available in PDF format.

Salud Urbana en América Latina (SALURBAL), is a five-year project launched in April 2017. The Drexel University Dornsife School of Public Health and partners throughout Latin America and in the United States are working together to study how urban environments and urban policies impact the health of city residents throughout Latin America.
More specifically, it is addressed in this sudy...
Analytical process for building the profiles was developed in two domains: Urban Landscape and Street Design.
The map presents the 1.351 sub-cities for the 10 selected Latin America countries.
This boxplot presents the distribution of the Number of Urban Patches (y-axis) by country (x-axis).
As in the previous chart, here is presented the distribution of the Area-Weighted Mean Shape Index (y-axis) by country (x-axis).
Based on the variables previously mentioned, 6 Urban Landscape profiles are identified applying clustering algorithms. As showed in left chart, the profiles are identified by different color hues.
To identify the contribution of each variable to the identified profiles, a scatter plot matrix shows the 6 variables in the y and x-axis. As described in previous slide, color hue is used to represent the assigned profile. Sub-cities can be selected by a drag selection or by country.
These profiles can be analyzed in terms of exogenous variables to identify associations with the profiles. The sub-cities are shown for each exogenous variable (x-axis) and for each profile color (y-axis and color hue). Sub-cities can be selected by a drag selection or by country.

黒の手番です。33 はどう動かしますか？


There is no definitive answer to this question. The answer depends on the scale of your application and the team that is involved. To be as flexible as possible, Express makes no assumptions in terms of structure.
Routes and other application-specific logic can live in as many files as you wish, in any directory structure you prefer. View the following examples for inspiration:
Also, there are third-party extensions for Express, which simplify some of these patterns:
Express has no notion of a database. This concept is left up to third-party Node modules, allowing you to interface with nearly any database.
See LoopBack for an Express-based framework that is centered around models.
Authentication is another opinionated area that Express does not venture into. You may use any authentication scheme you wish. For a simple username / password scheme, see this example.
Express supports any template engine that conforms with the
(path, locals, callback)
signature. To normalize template
engine interfaces and caching, see the
consolidate.js
project for support. Unlisted template engines might still support the
Express signature.
For more information, see Using template engines with Express.
In Express, 404 responses are not the result of an error, so the error-handler middleware will not capture them. This behavior is because a 404 response simply indicates the absence of additional work to do; in other words, Express has executed all middleware functions and routes, and found that none of them responded. All you need to do is add a middleware function at the very bottom of the stack (below all other functions) to handle a 404 response:
Add routes dynamically at runtime on an instance of
express.Router()
so the routes are not superseded by a
middleware function.
You define error-handling middleware in the same way as other middleware,
except with four arguments instead of three; specifically with the
signature (err, req, res, next)
:
app.use(function (err, req, res, next) {
console.error(err.stack)
res.status(500).send('Something broke!')
})
For more information, see Error handling.
You don’t! There’s no need to “render” HTML with the
res.render()
function. If you have a specific file, use the
res.sendFile()
function. If you are serving many assets from
a directory, use the express.static()
middleware function.

At Digital Democracy, I worked with a team to design and develop an
internal web application tool for the management and visualization of
Digital Democracy's databases. At this time, the application manages
scripts that affect data in our California and New York databases, but is designed
to scale to all 50 states.
Some of my contributions inculded implementing a javascript map library to display
the status of script runs per state, providing functionality to view
script documentation as Markdown files, and developing documentation for
use of the site.
Project Description: "Have you ever wanted to take advantage of ambitious
young dreamers looking to make a name for themselves in a fantasy setting?
Well now you can! Buy beer! Buy food! Buy people!
There is no better time than now to become a venture capitalist."
Mercenary Manager is a medieval-themed managerial game in which players
attempt to obtain and maintain as many resources, (food, beer, and
mercenaries), as possible. It was developed in a team of six members over
a ten week period.
My responsibilities for the project included the impelemetation of the
HUD, collision detection algorithms, and development of game logic.
One of my tasks for OpenVSP was to implement "negative volumes" for its
CFD mesh routine. The subroutine for determining if a triangle in the
mesh should be deleted or not was never designed for such functionalities,
so a large code refactor was needed. Along with negative volumes, I
included "transparent volumes," or objects that are not affected when
overlapping with another "positive volume, but should be deleted if
overlapping with a "negative volume."
The number of edge cases made finding a concise solution difficult.
For example, my algorithm had to know how to handle a negative volume
inside a negative volume inside a transparent volume inside a positive
volume. Fringe cases such as these made determining whether to delete
a mesh triangle or not a challenging task.
During my 2015 Summer vacation, my beautiful girlfriend requested that I
create a mobile application to assist in recording data of various
subjects performing a variety of tasks. She needed this data to
investigate whether or not gender and hand dominance impact automobile
operators' abilities to navigate a vehicle while interfacing with a
touchscreen.
The upper left image is the homescreen of the application.
Users select a task
to complete by taping on one of the three images.
The first task is shown in the upper right corner. On each tap on a
numbered box, the numbers are randomly to different boxes. When a user
was asked to complete this task, they were told to select a specific
number three times. When they complete the task, they hit the button
labeled "Done." Then, their time is recorded and they are returned to the
homescreen.
The bottom left image shows the drag task. Users were asked to drag the
grey circle along the slider until the number at the end of the silder
matched the number above the slider. Like the previous task, their time
was recorded.
I completed this task on my own time with no prior Android experience.
As a final project for my parallel programming applied to computer animation class,
my partner and I chose to analyze the speedup from the host to a Xeon Phi as the
number of particles in a cube increase. The collision detection algorithm has a
complexity of O(n^2).
As the results from the chart show, little improvement was found by offloading the
the programs computing 2,000 and 10,000 particles, but quite a large speedup
was found by offloading the 100,000 particle program.
The bottom picture shows all cores on the Xeon Phi being occupied while running the
100,000 particle program.
