{% extends "base.html" %} {% load static %} {% block page_title %}Akshara Ganitha Programme{% endblock %} {% block content %}
Mathematics is largely considered by students - and some teachers - as a "dreaded subject”, and is being taught without experiential learning. Akshara Ganitha program is designed keeping principles of constructivism in mind for joyful learning of math in classes 1 to 5.
It is designed as a support for primary school Maths teachers to ensure that the key goals set by National Curriculum Framework-2005 for teaching of Mathematics. This is achieved without being a burden on the teachers themselves as the programme dovetails with the current textbooks, classroom instruction practices, examinations and reporting requirements in government schools.
The objective of Akshara Ganitha program is:
The program will cover all the topics prescribed in the textbook / syllabus, however, the sequence of introduction may be altered. It will be divided in four areas (aligning broadly with the areas defined in the syllabus): Number Concepts, Money & Measurements, Geometry and Data Handling.
A child creates her own knowledge by engaging with the concrete teaching learning materials in the kit while the teacher facilitates the process. The methodology introduces concepts in a graded manner focussing on the broader vision of mathematics. The focus is on the activity based experiential learning that enhances child’s ability to think mathematically, see patterns and structures and handle abstractions rather than rote memorisation or mastering procedures.
Once the teacher introduces a concept, children explore it further (reinforcement) in a group of 4-6 children using concrete material with the help of a group leader.
Once a set of linked concepts are introduced, children’s understanding is evaluated by providing further hands on group exercises and by inter-group quizzes in the form of a chapter end evaluation.
Akshara has appointed the Cluster facilitators (CFs)- the ‘foot soldiers’ who will be monitoring the programme interms of usage of TLM, Group activities and extend their on the spot support to the teachers in each geograpghy. CFs are typically qualified in Education Program and Akshara has an in-built capacity building strategis for them. CFs invest significant effort in educating the community on their role in school functioning as well as they drive the attentions of the parents on the Learning status of the concerned school and the imputs given by Akshara. They work closely with self help group, local leaders, School Development and Monitoring Committee (SDMC), parents etc.
To find out the impact of the program a longitudinal research study (for three years) - Randomized Controlled Trial (RCT) - is designed to evaluate program effectiveness right at the beginning and just before the implementation of the project started in 2012-13 in geographies where the program was implemented. The research methodology considers an educational cluster randomly selected from all the clusters of treatment block as treatment group and another cluster with homogeneous parameters in terms of number of schools, teachers, children and teacher qualification, from an adjacent educational block as control group to compare and contrast the effectiveness of the program. The RCT design follows an approach of collecting learning outcomes of children, classroom process data and the ethnographic data for multiple cycles during the school academic year to get a sense of their progress, or the grey areas.

Two standard dice are rolled. If neither shows a 1, their sum is added
to the turn total.
If a single 1 is rolled, the player scores nothing and the turn ends.
If two 1s are rolled, the player’s entire score is lost, and the turn
ends.
If a double is rolled, the point total is added to the turn total as
with any roll but the player is obligated to roll again.
If a player chooses to "hold", their turn total is added to their
score, and it becomes the next player's turn.
The first player to reach the score wins.

| SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
Provides a hook into the rendering pipeline of compiled Object3Ds. For any
other object, the methods of this interface will never be called even if an
implementation of it is attached to that object. This is meant to be used for
executing your own OpenGL (or whatever...) code directly in the render
pipeline. Can be useful to set up your own vertex and/or fragment shaders for
an Object3D for example.
A render hook is attached to an Object3D. However, this doesn't mean that
it's only called once per object. In fact, an object can be compiled into
hundreds of display lists/vertex arrays. These methods will be called for
each of them, if they are going to be rendered in this frame.

Hashing for large scale similarity
Similarity computation is a very common task in real-world machine learning and data mining problems such as recommender systems, spam detection, online advertising etc. Consider a tweet recommendation problem where one has to find tweets similar to the tweet user previously clicked. This problem becomes extremely challenging when there are billions of tweets created each day.
In this post, we will discuss the two most common similarity metric, namely Jaccard similarity and Cosine similarity; and Locality Sensitive Hashing based approximation of those metrics.
Jaccard Similarity
Jaccard similarity is one of the most popular metrics used to compute the similarity between two sets. Given set and , jaccard similarity is defined as
Let’s define tweet as
where each tweet is represented by a set of users who clicked the tweet. The jaccard similarity between and is given by
Cosine similarity
Cosine similarity is a vector space metric where similarity between two vector and is defined as where, is a dot product and is norm operator.
Jaccard similarity ignores the weights as it’s a set based distance metric for e.g. number of user clicks. Lets define
where the number indicates the number of times user clicked tweet . Now, the tweets can be represented in user’s vector space as
and the cosine similarity is given as
Limitations
Pairwise similarity scales quadratically both in terms of time and space complexity. Hence, finding similar items is very challenging for a large number of items. In the following section, we discuss locality sensitive hashing to address these limitations.
Locality Sensitive Hashing (LSH)
Hashing is a very widely used technique that assigns pseudo-random value/bucket to objects. Hash functions must be uniform i.e. each bucket is equally likely. Locality Sensitive Hashing(LSH) is a hashing based dimensionality reduction method that preserves item similarity. More precisely, LSH hashes items to buckets such that similar items map to the same bucket with high probability. Such hash signatures can be used for efficient neighborhood search as well as to compute similarity between items on the fly.
Minhash
First, lets define
Let be a hash function that maps an object to a positive integer. The minhash is defined as
a function that returns the item with smallest hash value. Now, a k-dimensional minhash signature is defned by hash functions
Given , jaccard similarity of item & is defined as
where is an indicator function.
Minhash explained
Although theoretical proof is quite rigorous, the key idea is very intuitive. First, let’s define,
a) How many ways can we shuffle such that is the first element?
Ans: 3!
b) More generally, how many ways can we shuffle such that is the first element?
Ans:
Hashing a set of items is equivalent to generating a random permutation of the set. So, , only if the hash function assigns smallest value to i.e . From this observation, we can conclude
Hence, minhash approximates jaccard similarity.
Simhash
Let be a random vector passing through origin. Let’s define a simhash function for tweet
where,
Given simhash, can be defined as
Now, the angle between and is defined as
Simhash explained
In this section, we discuss the intuition behind approximation of cosine similarity using simhash.
In the figure above, for the vector , the pink shaded area corresponds to the half-space where , for eg. . On the other hand, the white region corresponds to the half-space where , for eg.
Lets consider two vector , and is an angle between them as shown in figure above. For a randomly drawn a vector passing through origin
is true only if vector lies in purple or white shaded area (i.e other than pink and blue shaded area). From this observation, we can define
Hence, simhash approximates cosine similarity.
In the next post, I will discuss more about implementation of minhash and simhash.

BATMAN AND ROBIN A film review by Michael John Legeros Copyright 1997 Michael John Legeros
(WB) Directed by Joel Schumacher Written by Akiva Goldsmith Cast Arnold Schwarzenegger, George Clooney, Chris O'Donnell, Uma Thurman, Alicia Silverstone, Michael Gough, Pat Hingle, Elle Macpherson, John Glover, Jeep Swenson MPAA Rating "PG-13" Running Time 130 minutes Reviewed at Mission Valley Cinemas, Raleigh, NC (18JUN97)
==
While a complete review is in the works, I can report that BATMAN AND ROBIN is easily the most light-hearted of the franchise. Though not quite the camp classic that director Joel Schumacher obviously intended, it delivers many a hearty Batlaugh, from Schwarzenegger's see-'em-a- mile-away one-liners to Thurman's wonderfully punny innuendo. (To the diamond- stealing Mr. Freeze, Poison Ivy purrs "I'll help you grab your rocks.") As usual, the villains steal the show-- what else is new?-- but at least the heroes get a bigger share of the screen time. Chris O'Donnell is, again, the most believable on the dramatic front. Clooney is the best *looking* Bruce Wayne to date, but, well, he smiles too much. Ms. Silverstone, making her debut as Batgirl, is adequate and little else. More action-figure action, much of it way-over-the-top, from sky-surfing without parachutes (!) to a vehicle chase down the arm of a giant statue. Great production design, too. (The most accomplish- ed of the four films, I'd say). Like all the Batfeatures before it, however, the film's greatest failing is in the editing. Nips and tucks (and even some slices) are needed all over the place. And what's with the repetitive score? Definitely not for purists.
Grade: B- (preliminary)

After consulting various traditional Greek recipes and adding my own personal touch, this recipe was born.
I love playing around with popular dishes from other cultures and turning it into my own. Don't let the length
of this recipe scare you, each section is fairly easy and quick to make.
Prep time: 25 minutes
Cook time: 130 minutes
Serving: 4 (1x 26cm casserole dish)
Ingredients: eggplant layer
- 2 large eggplants
- salt
- avocado oil for frying
Ingredients: meat layer
- 25g butter
- 1 small onion, finely chopped
- 2 cloves of garlic, minced
- 750g lamb or beef mince
- 1 tin tomatoes
- 1 cup lamb or beef stock
- 1 tbsp erythritol
- ½ tsp salt
- ¼ tsp pepper
- 2 bay leaves
- 1 tsp dried oregano
- 1 tsp dried parsley
- 1 cinnamon stick
Ingredients: béchamel layer
- 1 small-medium head cauliflower (+-450g)
- 1 cup cream
- 1 cup milk
- 3 large egg yolks
- ¼ tsp salt
- ¼ nutmeg
- 100g parmesan, grated
Instructions: eggplant layer
- Slice the eggplants into 2cm thick rounds.
- Salt the rounds and leave for 20 minutes.
- Rinse off the salt and pat dry.
- Fry the eggplant rounds (on a high heat) in avocado oil for 3 minutes each side or until golden brown.
- Layer the eggplant on the bottom of the casserole dish.
Instructions: meat layer
- Finely chop the onions and mince the garlic.
- Melt the butter in a large sauce-pan and add the onions. Leave the onions to fry on a medium, low heat until soft and golden brown.
- Add the garlic and mince and fry for another 2-3 minutes.
- Add the rest of the ingredients and leave uncovered to simmer for 40-60 minutes.
- The longer you leave the mince to simmer, the richer and more developed the flavour will be.
- Add the mince on top of the eggplant layer.
Instructions: béchamel layer
- Preheat the oven to 200°C.
- Break the cauliflower up into small florets and spread out on a baking tray.
- Roast in the oven for 15-20 minutes (unil it starts to brown).
- When the cauliflower is ready. Combine it with the rest of the ingredients and blend.
- Turn the oven down to 180°C.
- Pour the béchamel on top of the mince layer.
- Bake in the oven for 30 minutes on 180°C.
- Turn the heat up to 200°C and set to grill, leave for another 5-10 minutes until golden brown on top.
Tip
You can cook the mince in your slow cooker for 6-8 hours.
For the best results use a good quality stock.
The cultivation of eggplants have changed and they don't need to
be salted as much but it's a step I still like to add in case the eggplant is bitter.
This recipe may seem like a long one but you can very easily multi-task and get things done while waiting for other elements.
Live long and keto-on!

I have lhs rhs : expr
, and I would like to know, if the goal were to be lhs = rhs
, whether or not refl
would succeed. I could temporarily make the goal actually lhs = rhs
, and try refl
, but I'm wondering if it can be done directly.
I'm only hesitant to overwrite the goal because the actual current goal may be something completely unrelated to what my tactic is thinking about that the moment it's wondering about lhs = rhs
, and it feels kludgy to actually have to use set_goal
.
The problem is that refl
is basically just shorthand for mk_const `eq.refl >>= λ r, apply_core r
, and apply_core
only unifies with the goal.
@Scott Morrison Take a look at tactic.solve_aux
Thanks @Sebastian Ullrich. Implicit in your answer is "get over it, just set_goal to whatever you want, it's how you're meant to do this"! Good to know.
If you want to look at it like that, yes :)
What if you try to unify them directly? unify lhs rhs

I was watching the video:
While the main result is beautiful, what caught my attention was the beautiful so-called Inverse Pythagoras Theorem
Of course, we know the Pythagorams Theorem:
$a^2 + b^2 = c^2$
To state the "Inverse Pythagoras Theorem", draw a perpendicular from the right angle to the hypotenuse, and call its length $h$:
The inverse Pythaogoras Theorem says:
$\frac{1}{a^2} + \frac{1}{b^2} = \frac{1}{h^2}$
Proving it is straight forward:
$ar(\triangle ABC) = ar(\triangle ADC) + ar(\triangle BDC)$
$\frac{1}{2}ab = \frac{1}{2}h.AD + \frac{1}{2}h.BD$
$ab = h.(AD + BD)$
$ab=hc$
$c = \frac{ab}{h}$
Now, put this in Pythagoras theorem identity:$a^2 + b^2 = (\frac{ab}{h})^2$
Rearranging:
$\frac{1}{a^2} + \frac{1}{b^2} = \frac{1}{h^2}$I must have proved it many times, but looking at it with the name "Inverse Pythagoras Theorem" gave me a new respect for it.

S&P 500 Posts Best First Half in 22 Years
A banner June followed a dismal May; S&P ends second quarter up 3.8% and has risen 17% in 2019
Stocks notched solid gains in the second quarter thanks to a perceived shift in the Federal Reserve’s appetite for interest-rate cuts, extending a rally that propelled the S&P 500 to record highs.
The benchmark overcame an escalation in the U.S.-China trade fight to close Friday up 17% so far this year, its best first-half performance since 1997. That prolonged the more than a decadelong bull market for stocks and erased steep losses that jarred investors at the end of last year.
Stocks also rose despite mounting fears of an economic slowdown that have pushed bond yields down globally. The yield on the 10-year U.S. Treasury closed the quarter at 2%, nearly a half-percentage-point drop from the end of March, a downward lurch that took many investors by surprise.

Deutsche Bank reportedly considering up to 20,000 job cuts
Deutsche Bank is considering cutting 15,000 to 20,000 jobs, or more than one in six full-time positions globally, the Wall Street Journal reported on Friday, citing people familiar with the discussions.
The layoffs would probably take place over more than a year and would spread across regions and businesses, the Journal said.
Top-level talks about the restructuring took place on Thursday and Friday, but no final decisions have been made, a source close to the matter told Reuters.
Deutsche Bank is completing a plan that may eliminate hundreds of positions in equities trading and research, as well as derivatives trading, as part of a broad restructuring, Bloomberg reported on Friday, citing sources.
Sources told Reuters last week that the bank plans to cut the size of its U.S. equities business, leaving only a skeleton operation in place to service corporate and high-net-worth clients.

Fed Chief Jerome Powell warns against policy bending to ‘short-term political interests’
Federal Reserve Chairman Jerome Powell stressed the central bank’s independence in a speech Tuesday that comes amid continuous pressure from the White House to cut interest rates.
He spoke during a event at the Council on Foreign Relations in New York that investors were watching closely for clues about the direction of monetary policy.
His remarks mirrored those from last week’s Federal Open Markets Committee meeting, and he emphasized that policy is under review though he did not overtly tip his hand that a rate cut is at hand. Markets are currently pricing in four quarter-point reductions by April 2020.
“Since the beginning of the year, we had been taking a patient stance toward assessing the need for any policy change,” he said. “We now state that the Committee will closely monitor the implications of incoming information for the economic outlook and will act as appropriate to sustain the expansion, with a strong labor market and inflation near its symmetric 2 percent objective.”

The Fed is doing something new: listening to low-income workers
Low-income communities are finally feeling the expansion. The Fed is noticing.
When Jerome Powell, the chair of the Federal Reserve, gives a press conference, Fed reporters and market analysts pore over every word, looking for hints about the Fed’s plans and what they might mean for the economy. So it was striking that a few of the more important and unusual comments from Powell’s presser last week went largely unnoticed. Allow me to correct that here.
First, a bit of context. A few weeks ago, Powell attended a “FedListens” conference in Chicago. It’s something of a listening tour for the Fed to help review its “monetary policy strategy, tools, and communications.” As part of the initiative, the central bank is holding numerous conferences throughout the year, during which it can hear from outsiders to help inform its review.
During one panel in Chicago, Maurice Jones, president of the Local Initiatives Support Corporation (LISC), a national organization that works with local partners to bring economic opportunity to places that have too little of it, was asked by the moderator, Boston Fed president Eric Rosengren, about the implications of tight labor markets — meaning low unemployment, such as we have at the moment — for the low-income communities that LISC serves.

Individuals with different motivations often report seeing the same image differently, but it is unclear whether this reflects a bias in what they *see* or what they *report* seeing. Can people with diverse goals and motives truly perceive the same visual stimuli differently? In recent work, I combined computational modeling and fMRI to provide a neurocomputational account of how motivation biases visual perception.
When presented with the identical political content, conservatives and liberals tend to interpret information in a manner that supports their existing beliefs. These biases contribute to increasing ideological polarization in America. What psychological and neural processes drive the divergent processing of political information? To address this question, we employed a novel multimethod approach that combines fMRI with semantic analyses of naturalistic political content.
People are motivated to seek out socially valued individuals in their community (i.e. people who are trustworthy, supportive and well-connected). How do people identify these individuals? What happens when expectations of social value are misinformed, for example, when someone is less trustworthy than their reputation suggests? In this line of work, I use fMRI, social network analyses and computational modeling to examine how social value guides social interactions.
In a separate line of work, my collaborators and I have studied the neural bases of human communication. We found that (1) experiencing, (2) talking about and (3) listening to a verbal description of an event elicits shared patterns of neural activity across individuals. The fidelity of this neural pattern correlated with communication success. These results suggest that communication is associated with the construction of shared neural representations.


var x;
x = 6;
var y,
z = 8;
a = 'Some string';
var a; // Hoisting
ES2015/ES6:
let x;
x = 6;
const z = 8; // In Java → final
y = 8; // ReferenceError: y is not defined
let y;
var is scoped/visible to the nearest function block
let is scoped/visible to the nearest enclosing block
let vs. var
function myFunction() {
//a is *not* visible out here
//b is *not* visible here
//c is visible here, but the value is undefined
for( let a = 0; a < 5; a++ ) {
//a is only visible in here (and in the for() parentheses)
//c is visible here
}
//a is *not* visible out here
//c is visible here, but the value is undefined
let b = 5;
var c = 10;
}
If we replace let a = 0 with var a = 0 it will be visible in the whole function
Primitive types
// boolean
let isDone = false;
// number
let decimal = 8; // or Infinity, NaN
let hex = 0xf00d;
let binary = 0b1010; // new in ES2015/ES6
let octal = 0o744; // new in ES2015/ES6
// string
let color = 'blue';
// undefined, null
let x; // undefined
let y = null;
RegExp
let regExp = /.*/gi; // In form /pattern/modifiers, without quotes
let regExp = new RegExp('.*', 'gi');
// returns true/false if matches
regExp.test('The best things in life are free!');
// returns first matched text or null
/e/.exec('The best things in life are free!');
// Returns an array containing matches
let urlExp = /^((https?)\:\/\/)?(([^:\/?#]*)(?:\:([0-9]+))?)...$/
let urlParts = 'https://dbg.com:8080/somePath'.match(urlExp);
let protocol = urlParts[2];
switch (new Date().getDay()) {
case 0:
day = 'Sunday';
break;
case 1:
day = 'Monday';
break;
...
default:

}
Expression can evaluate to any type. For expression in cases a strict comparison (using
===) is done.
switch statements
let a = 100;
let b = NaN;
switch (true) {
case isNaN(a) || isNaN(b): // === true
console.log('NaNNaN');
break;
case a === b: // === true
console.log(0);

Semicolons
let a, b, c
a = 5;
b = 6
c = a + b;
let f1 = (a) => {
return a
}
let f2 = (a) => {
return
a
}
f1(2) → 2
f2(2) → undefined
Semicolons are not required, but after return there has to be a value on the same line
→ otherwise undefined

Functions
Function Syntax
function name(parameter1, parameter2, parameter3) {
code to be executed
}
let name = function (parameter1, parameter2, parameter3) {
code to be executed
}
name(1, 'a', new Date());
Functions are treated as values:
can be returned
can be assigned to variables and object attributes
can be an argument of other function
→ We can define functions in function body
ES2015/ES6
let name = (parameter1, parameter2, parameter3) => {
code to be executed
}
let name = (parameter1, parameter2) => parameter1 + parameter2;
let name = parameter1 => parameter1.toString();
name(new Date());
Complex examples
// Returns a function
let getRandomGenerator = () => {
return () => Math.random();
};
// Parameter is a function
let generate = (generator) => generator();
// Call the generate method
console.log(generate(getRandomGenerator()));
// Call the generate with different generator method
console.log(generate(() => Math.ceil(Math.random() * 100)));
ES2015/ES6 - Extended parameter handling
function f (x, y = 7, z = 42) { // ES2015/ES6 default values
// ES5: y = y || 7; ...
return x + y + z
}
f(1) === 50
function f (x, y, ...a) { // ES2015/ES6 rest parameter
// ES5 a = Array.prototype.slice.call(arguments, 2);
return (x + y) * a.length
}
f(1, 2, "hello", true, 7) === 9 // (1 + 2) * (a.length = 3)
4
Scope and closures
Scope
let a = 1; // Global scope: everything registered under
// window/script, eg. window.a = 1 (script in case of let)
function f1() {
let b = 2 + a; // Outer function scope
// c is *not* visible here
return () => {
b += 2;
let c = a + b; // Inner function scope
return c;
};
// c is *not* visible here
}
// b is *not* visible here
// c is *not* visible here
Closures
Closures are functions that refer to independent (free) variables (variables that are used locally, but
defined in an enclosing scope). In other words, these functions 'remember' the environment in which they
were created.
let f2 = f1(); // A new closure created!
a = f2(); // a and b were modified => window.a = 6, f2.f1.b = 5
a = f2(); // a and b were modified => window.a = 13, f2.f1.b = 7
let f3 = f1(); // A new closure created! f2.f1 !== f3.f1
Closures
let a = 1; // Global scope
function f1() {
let b = 2 + a; // Outer function scope
// a is *not* visible here
return () => {
b += 2;
let c = a + b; // Inner function scope
debugger;
return c;
};
}
let f2 = f1();
let f3 = f1();
5
Objects
Object literals - JSON-like
let person = {
firstName : 'John',
lastName : 'Doe',
age : 50,
eyeColor : 'blue',
doSomething : () => { ... }
};
let f = () => ({
a : 'b',
c : 'd'
[ 'string' + Math.random() ] : 'e' // ES2015/ES6
myMethod (a, b) { ... } // ES2015/ES6
});
f({ ... });
Literals does not have type → they are instances of an Object
Construction function
function Person(first, last, age, eye) {
// this = {};
this.firstName = first;
this.lastName = last;
this.age = age;
this.eyeColor = eye;
this.doSomething = () => { ... }
// return this;
}
let myFather = new Person('John', 'Doe', 50, 'blue');
let myMother = new Person('Sally', 'Rally', 48, 'green');
myFather instanceof Person === true
Function's this
console.log(this === window); // true; Global context
function f1() {
return this; // window
}
function f2() {
'use strict'; // see strict mode
return this; // undefined
}
f1.call({}, 1, 2); // this is replaced by {}
f1.apply({}, [1, 2]); // this is replaced by {}
f2.bind({}); // ES 5.1 only
f2(); // this is replaced by {}
Function's this in objects
function Car() {
this.f = function() { return this };
}
let a = new Car();
a.f() // this === a
function f(x) { return x(); }
f(a.f); // this === window / undefined
f(a.f.bind(a)); // this === a; ES 5.1 only
ES2015/ES6 - Lexical this
In arrow functions only
call, apply and bind cannot be used
this.nums.forEach((v) => {
if (v % 5 === 0)
this.fives.push(v)
})
// ECMAScript 5
var self = this;
this.nums.forEach(function (v) {
if (v % 5 === 0)
self.fives.push(v);
});
// since ECMAScript 5.1
this.nums.forEach(function (v) {
if (v % 5 === 0)
this.fives.push(v);
}.bind(this));
Object.prototype
All JavaScript objects inherit the properties and methods from their prototype.
Objects created using an object literal (or with new Object()) inherit from a prototype called
Object.prototype.
The Object.prototype is on the top of the prototype chain.
All JavaScript objects (Date, Array, RegExp, Function, ....) inherit from the
Object.prototype.
Object.prototype
function Person(first, last, age, eye) {
...
}
Person.prototype.nationality = 'English';
Person.prototype.name = function() {
return this.firstName + ' ' + this.lastName;
};
let myFather = new Person('John', 'Doe', 50, 'blue');
console.log(myFather.name());
Prototype inheritance
function Teacher(first, last, age, gender, interests, subject) {
Person.call(this, first, last, age, gender, interests);
this.subject = subject;
}
Teacher.prototype = Object.create(Person.prototype);
Teacher.prototype.constructor = Teacher;
Teacher.prototype.greeting = function() { ... }
ES2015/ES6 Class
class Person {
constructor (first, last, age, eye) {
this.first = first;
...
}
name() {
return this.firstName + ' ' + this.lastName;
}
}
let myFather = new Person('John', 'Doe', 50, 'blue');
Class inheritance
class Teacher extends Person {
constructor (first, last, age, eye) {
super(first, last, age, eye);
}
greeting() {
super.someMethod();
}
}
// ES5
Teacher.prototype.greeting = () => {
Person.prototype.greeting.apply(this, arguments);
}
function car () {}
let a = new car
a instanceof car // true
a instanceof car.prototype.constructor // true
car === car.prototype.constructor // true
car.prototype.constructor = function () {}
a instanceof car.prototype.constructor // false
a instanceof car // true
Expressions
JavaScript evaluates expressions from left to right. Different sequences can produce
different results.
Values are automatically converted if needed (for all operators except ===
and !==)
Avoid type conversions as much as possible → slow and unpredictable
Conversions
let x = 16 + 4 + 'Volvo';
// x → 20Volvo
x = 'Volvo' + 16 + 4;
// x → Volvo164
x = 'Volvo';
let y = 8 - x;
// y → NaN
x = 4;
y = 8 - x;
// y → 4
x = '5' + 4 // → 54
x = '5' - 4 // → 1
let x = ...;
if(!x) { // Evaluates to true if x is convertible to false
x = ...;
}
// Logical "or" evaluates to the first operand that is convertible
// to true
x = x || {}; // Evaluates to {} if x is convertible to false
// To check for null/undefined only
// Only undefined can be converted to null
if(x != null) { // x == null
...
}
ES2015/ES6 - Spread Operator
let params = [ 'hello', true, 7 ]
let other = [ 1, 2, ...params ] // [ 1, 2, 'hello', true, 7 ]
f(1, 2, ...params) === 9
let str = 'foo'
let chars = [ ...str ] // [ 'f', 'o', 'o' ]

JavaScript Transpilers
(source-to-source compilers)
Tomorrow's JavaScript, Today → write your code in next generation syntax
Convert ES2015 sources to ES5 → better cross-browser support
one of the few ways for asynchronous execution in JavaScript
executed after specified period
executed once the browser is idle
setTimeout(() => { console.log('I\'m running in a "new thread".') });
window.console
console.error(...) // any object
console.warn(...) // any object
console.info(...) // any object
console.log(...) // any object
console.trace(...) // any object
console.dir(...) // any object
console.time(name) // name is a string
console.timeEnd(name) // name is a string
console.group(name) // name is a string
console.groupEnd(name) // name is a string
JSON
(JavaScript Object Notation)
There is native support in both browsers and Node.js
let myObject = JSON.parse('{ "a": 1, "b": "some string" }');
let stringValue = JSON.stringify(myObject);
window.localStorage, window.sessionStorage
window.localStorage - stores data with no expiration date
window.sessionStorage - stores data for one session (data is lost when the browser
tab is closed)
localStorage.setItem('lastname', 'Smith');
let myValue = localStorage.getItem('lastname');
localStorage.removeItem('lastname');
history → Browser's history API - since HTML5
pushState/replaceState(...)
screen → Information about screen device
10
DOM model
HTML DOM
All the elements of an HTML document are represented as DOM objects
Root object is window.document
All DOM objects have properties, methods (and events in case of elements)
window.document
Represents the web page.
document.getElementById(id) // Find an element
document.getElementsByTagName(name) // Find elements
document.getElementsByClassName(name)
document.querySelector(cssSelector) // Find by css selectors
document.createElement(element) // Creates a new element
document.appendChild(element) // Appends a new child
document.write(text) // Replace content
Nodes vs. Elements
All DOM objects are Node instances.
Node.nodeType represents the type of the node.
Elements have type Node.ELEMENT_NODE
Attributes, comments, text nodes, etc. are also Node instances
Attributes are stored in Element.attributes
Other nodes are stored in Node.children
Properties vs. Attributes
Property is a value stored in a browser's memory (DOM object) and can be changed
Attribute is set by developer in HTML and is used by browser as initial value for the
corresponding property.
Properties are often referenced as attributes, but the actual attributes are stored as DOM Attribute
nodes.
Useful properties of elements
// element.style allow access to all CSS properties
element.style.fontSize = '16px';
element.classList // Map based object for class manipulation
element.value
element.textContent
element.innerHtml
element.outerHtml
Returns whether or not a specific event is a bubbling event
cancelable
Returns whether or not an event can have its default action prevented
currentTarget
Returns the element whose event listeners triggered the event
defaultPrevented
Returns whether or not the preventDefault() method was called for the event
eventPhase
Returns which phase of the event flow is currently being evaluated
isTrusted
Returns whether or not an event is trusted
target
Returns the element that triggered the event
timeStamp
Returns the time (in milliseconds relative to the epoch) at which the event was created
type
Returns the name of the event
view
Returns a reference to the Window object where the event occurred
Event object
Method
Description
preventDefault()
Cancels the event if it is cancelable, meaning that the default action that belongs to the
event will not occur
stopImmediatePropagation()
Prevents other listeners of the same event from being called
stopPropagation()
Prevents further propagation of an event during event flow

Execution timing and ES2015/ES6 Promise
From MDN:
A Promise is a proxy for a value not
necessarily known when the promise is created. It allows you to associate handlers with an
asynchronous action's eventual success value or failure reason. This lets asynchronous methods
return values like synchronous methods: instead of immediately returning the final value, the
asynchronous method returns a promise to supply the value at some point in the future.
let myFirstPromise = new Promise((resolve, reject) => {
... resolve(anyData); ...
... reject(someErrorData); ...
});
let myFirstPromise = new Promise((resolve, reject) => {
setTimeout(() => {
... resolve(anyData); ...
... reject(someErrorData); ...
}, 100);
});
Promise.resolve and Promise.reject
// new Promise((resolve) => resolve(52));
let myPromise1 = Promise.resolve(52);
// new Promise((resolve, reject) => reject('Error!'));
let myPromise2 = Promise.reject('Error!');
Promises are great to simplify async code, callbacks
Executed on microtask queue
If the execution take long use setTimeout → does not block the browser
RECOMMENDATION: using Promise for all tasks leverages time spent on main task queue
→ page renders and responds faster
ECMAScript 2017 - ES8 (Sneak peek)
function resolveAfter2Seconds(x) {
return new Promise(resolve => setTimeout(() => resolve(x), 2000));
};
// async function expression assigned to a variable
const add = async function(x) {
const a = await resolveAfter2Seconds(20);
const b = await resolveAfter2Seconds(30);
return x + a + b;
};
add(10).then(v => {
console.log(v); // prints 60 after 4 seconds.
});
ECMAScript 2017 - ES8 (Sneak peek)

return new Promise(resolve => setTimeout(() => resolve(x), 2000));
};

Modules
Why modules?
Traditional objects
Small units
Limited responsibility
Defined in global scope → name clashes
Everything is public
Modules
Composition of multiple objects, constants, etc. under single unit
Namespaces to bundle multiple objects → no name clashes
Transparent scopes
Only API is exported
Modules - Naive approach
function Car() { ... }
let carModule = {
Car : Car,
someProperty: 2,
...
}
let myCar = new carModule.Car();
let prop = carModule.someProperty;
＋ Namespace to bundle multiple objects
－ Defined in global scope → name clashes
Modules - IIFE
Immediately-Invoked Function Expression
a = b + c // without ; interpreted as a call to the last term
;(function(global) {
function Car() { ... }
global.carModule = {
Car : Car,
someProperty: 2,
...
}
})(window); // Or "global" in Node.js or any other object
let myCar = new carModule.Car();
let prop = carModule.somePropery;
＋ Defined in function's scope → no name clashes
＋ Only some members are "exported"
－ Scripts are loaded and executed on DOM load
Advance module systems

CommonJS (CJS)
Developed for server-side environments
Synchronous dependencies management
Allows cyclic dep. → unfinished copy of the "exports" object
// module A (a.js)
// let moduleA = { exports: {}, id: 'file path', ... },
// (function(module) {
// let exports = module.exports;
exports.Car = function Car() { ... }
module.exports.someProperty = 2;
// })(moduleA);
// module B (b.js)
let moduleA = require('./a.js'); // Global function
let myCar = new moduleA.Car();
// exports = ... overrides local variable "exports"
module.exports = {
carInstance: myCar
};
CommonJS - Cycles
// a.js
let b = require('./b.js');
exports.foo = function () { ... };
// b.js
let a = require('./a.js'); // (1)
a.foo(); // NOT OK (2)
// Can’t use a.foo in module body,
// but it will be filled in later
exports.bar = function () {
a.foo(); // OK (3)
};
// main.js
let a = require('./a.js');
CommonJS (CJS)
Dependencies not known prior to execution/loaded on demand:
Dependencies can't be loaded asynchronously (are not known) prior to module body
execution
require is blocking the task queue
Native support in Node.js or MongoDB :)
Browser support: Browserify, SystemJS
AMD
Asynchronous Module Definition
Developed for browsers
Does not allow cyclic dependencies
// module A (a.js)
define(function() {
function Car() { ... }
return {
someProperty: 2,
Car: Car;
}
});
// module B (b.js)
define(['./a.js', 'exports', 'module'],
function(moduleA, exports, module) {
let myCar = new moduleA.Car();
exports.carInstance = myCar;
exports.moduleId = module.id;
});
AMD
Compatible with CommonJS
// module B (b.js)
define(['./a.js', 'exports'],
function(moduleA, exports) {
// Synchronously loaded module using CJS style "require"
let commonJSModule = require('./commonJSModule.js');
// Dynamically (and async.) loaded module
require(['./someOtherModule.js'], function (otherModule) {
exports.asyncModule = otherModule;
});
});
// c.js
require(['./someModule.js'], function (someModule) {
someModule.doSomething();
});
AMD
Dependencies are known based on the arrays in define and require:
Such dependencies are loaded asynchronously prior to module body execution (modules have to be non-cyclic)
CommonJS style require is still blocking the task queue
// module A (a.js)
export class Car { ... }
export let someProperty = 2;
export { MY_CONST, myFunc };
export { MY_CONST as THE_CONST, myFunc as theFunc };
export * from 'src/other_module';
export default class Foo {}
// module B (b.js)
import theDefault, { Car, someProperty } from './a';
import theDefault from './a';
import { Car, someProperty } from './a';
import { Car as Automobile, someProperty } from './a';
import * as moduleA from './a';
import './a';
let car = new Automobile(); someProperty === '2'; etc.
ES2015/ES6 - Cycles
ECMAScript 6 modules export bindings, not values
//------ a.js ------
import { someMethod, foo } from 'b.js';
export function foo() { ... };
//------ b.js ------
// Can be translated to a = require('a.js'); (1)
import { foo } from 'a.js';
// Can’t use a.foo in module body,
// but it will be filled in later
export function bar() {
foo(); // a.foo → OK (2)
};
ES2015/ES6
Dependencies are known based on static analysis:
Dependencies can be loaded asynchronously prior to module body execution
Modules export bindings, not values - Cycles allowed
ES2015/ES6 contains module definition only; Specs for module loading is still a draft
Natively supported in ES2015/ES6 enabled environments, but currently with limitations: Chrome
60+,
FF 54+, Safari 10.1+, Edge 14+
Babel can produce all module formats from ES2015 (CommonJS or AMD suite the best;)
Modules are loaded via SystemJS, RequireJS or any other tool:
Flexible development
Code split into multiple files
Faster traspilation
Dependency injection
etc.
Production
Don't use modules in production → slower download times
Too many HTTP requests
Small files
One big bundle is much more faster to load and process
Use Webpack 2 or Rollup to create the IIFE result
Tree-shaking
Why ES2015 modules in development?
Webpack 2 or Rollup operate over ES2015 (natively), AMD or CommonJS
modules (with plugins)
Based on analysis of ES2015 modules they are able to "tree-shake" the final code → smaller
bundles → faster load times
Tree-shaking removes not used parts of code
With ES2015 we import only parts of modules, AMD and CJS imports everything → Makes TS faster

Nice job! You've gotten through the hardest part. Now that you can read memory, you have everything you need to defeat ASLR. We recommend the following high approach to getting a shell. We'll go into more detail about each of these below.
The ultimate goal of your exploit will be to get the program to call system("some command"), but in order to do that, have to know where in memory system is. Since the system has ASLR enabled, the location of system changes every time you run it, so you'll want to leak this information from the program, then use it to exploit it in the same connection.
So you got the ability to read any memory in the program - how do we find system given that? To answer this, it helps to understand some things how shared libraries work on Linux.
First of all, what is a shared library? You have have seen in previous problems that a lot of programs call functions like system, but each program doesn't define its own separate version of this function - that would be a lot of redundant code!
Instead, we have a single copy of the system that all the programs on the machine can share, hence a shared library. In more detail, every time you run a program, in addition to loading the program into memory, Linux also loads a shared library file into memory. The libc.so.6 file in the problem description is the shared library file for libc, the standard C library. This is the library that contains functions such as printf and system. If we can figure out where libc.so.6 is loaded in memory, then we can calculate the address of system.
So you may be wondering - if libc.so.6 is loaded at some random address, then how does the program know where to look when it wants to call a function like memcmp?
Roughly speaking, the answer is that when the program is initially loaded, the code which is doing the loading knows where the libraries are loaded and writes the correct addresses into the program. Specifically, the code writes the addresses into a table calle the Global Offset Table, or GOT. You can see this if you disassemble fancy_cache and look at the call to memcmp:
...
8048733: e8 18 fd ff ff call 8048450 <memcmp@plt>
...
Instead of going straight to the address of memcmp in libc, the call goes to 0x8048450, which looks like:
...
08048450 <memcmp@plt>:
8048450: ff 25 14 b0 04 08 jmp *0x804b014
8048456: 68 10 00 00 00 push $0x10
804845b: e9 c0 ff ff ff jmp 8048420 <_init+0x28>
...
0x804b014 is the address of memcmp's entry in the GOT.
There is one extra optimization that you should be aware about. Above, we said that at program load time, the loader code will fill in the correct address of all library functions that the program calls, but this isn't quite correct. Looking up the correct addresses of all the functions is expensive if there are a lot of them, and on any particular run of a program, it might only call a subset of the functions that had to be looked up at start time.
To avoid this, the loader doesn't actually look up the addresses for all of the libray functions at runtime. Instead, it writes the address of a function that can be used to do the slow lookup of where a libary function is into the program's memory. Initially, the GOT entries for each library function points to some code which calls this lookup function to find the library function. This function also updates the GOT so that future calls to the to library function don't need to relookup its location. This optimization is called lazy binding. Note how it requires the GOT to be writable. This will be useful later :-)
The takeaway is that once a library function has been called at least once, the GOT will contain the address of the function in the library. Once we have the address of one function in the library, can subtract an offset (in memcmp's case, 0x142870) to figure out where the library starts in memory, and once we know where the library starts, we can calculate the address of functions inside the library, like system!
Try modifying your exploit to leak the value at memcmp's GOT entry (0x804b014). You should get back an address ending with 0x870, and subtracting 0x142870 should tell you where libc.so.6 is loaded in memory (we call this the libc base address)
Notice now if you run your exploit multiple times, the address you get back is different each time - that means the ASLR is working :-)
Now we just need to find the offset of system in libc.so.6 and we can calculate where system is in memory. You can get this using the readelf command:
$ readelf -s libc.so.6 | grep system ... 243: 00119b20 73 FUNC GLOBAL DEFAULT 12 svcerr_systemerr@@GLIBC_2.0 620: XXXXXXXX 56 FUNC GLOBAL DEFAULT 12 __libc_system@@GLIBC_PRIVATE ...
The Xed out value is the offset of system. Go ahead and add it to the libc base address to find the address of system.
Now that you know how the GOT is used, it shouldn't be too surprising
that overwriting the GOT entry for memcmp with the address
of system will cause any calls to memcmp(arg1,
arg2)
to actually do system(arg)
.
Try modifying your exploit so that you can write arbitrary data to an arbitrary address after leaking the libc base. The technique should be pretty similar to how you got the read, except with CACHE_SET instead of CACHE_GET :-)
This last part should be pretty easy :-) Make sure to put your shell commands in the first argument. Awesome work - enjoy your flag!
