How to prove the Euclid's Algorithm - GCD
 
07:15
The Euclid's algorithm is widely used to find the GCD, short for Greatest Common Factor, of numbers. It uses interesting mathematical properties of division and remainders to find the answer. Here we prove the GCD algorithm once again to bring clarity to Euclid's method of dividing the larger number by the smaller one and setting the new parameters to the smaller and remaining number. Check out these videos on the code for the algorithm (https://youtu.be/80pOI0_BXyk) and an exciting question (https://youtu.be/D-DYtUmRMa4)!

Number Theory: Diophantine Equation: ax+by=gcd(a,b)
 
09:43
Once you know how to solve diophantine equations with a single variable, the next step in complexity is to consider equations with two variables. The simplest such equations are linear and take the form ax+by=c. Before we solve this equation generally, we need a preliminary result. We show that you can solve the equation ax+by=GCD(a,b) by performing the Euclidean algorithm, and then reverse-substituting to arrive at a single solution.

What is the Euclid's algorithm? - GCD Problem for HackerRank
 
17:11
For this HackerRank problem, we use the Euclid's algorithm to find the GCD (Greatest Common Divisor) of two numbers. The problem is based on the scene in Die Hard 3.0, where John McClane has to solve a mathematical problem based on this to save the city! The GCD of two given numbers is defined as the largest possible number which divides both the numbers with no remainder. The GCD of a number is also sometimes called Highest Common Factor. We take sample test cases to see how this problem can be solved, and then move to a proof for a general case. Make sure to check out the other two videos on the proof of the algorithm (https://youtu.be/B5HKW99AvV0) and the code (https://youtu.be/80pOI0_BXyk)!

Congruence (Modular Arithmetic) & 5 Properties Explained with 7 Problems: Ultimate Shortcuts
 
51:44
Modular arithmetic especially the properties of congruence are an important tool in arriving at quick solutions to a variety of problems. In this video Mayank unravels this concept of Congruence starting with the basic concepts and then explaining the 5 key properties of Congruence (≡): a+c ≡ (b+d)mod N (Remainder of Sums ≡ Sum of Remainders) a-c ≡ (b-d)mod N (Remainder of Difference ≡ Difference of Remainders) ac ≡ (bd)mod N (Remainder of Products ≡ Products of Remainders) a^e ≡ b^e mod N (Remainder of Exponent ≡ Exponent of Remainders) a/e ≡ b/e (mod N/gcd(N,e)) (However, don’t do division without writing basic equation Mayank applies these concepts to arrive at quick solutions for 7 representative problems - reducing seemingly impossible math involving large numbers to mere seconds. Some example problems from the video: Find the remainder 6^(6^(6^6 ) )/7 Find the last digit of (17)^16 There are 44 boxes of chocolates with 113 chocolates in each box.

Will Quantum Computers break encryption?
 
15:45
How do you secure messages over the internet? How do quantum computers break it? How do you fix it? Why don't you watch the video to find out? Why does this description have so many questions? Why are you still reading? What is the meaning of life? Facebook: https://www.facebook.com/frameofessence Twitter: https://twitter.com/frameofessence YouTube: https://www.youtube.com/user/frameofessence CLARIFICATIONS: You don't actually need a quantum computer to do quantum-safe encryption. As briefly mentioned at 7:04 , there are encryption schemes that can be run on regular computers that can't be broken by quantum computers. CORRECTIONS: [2:18] Technically, you can use any key to encrypt or decrypt whatever you want. But there's a specific way to use them that's useful, which is what's shown in the video. [5:36] In RSA, depending on exactly what you mean by "private key", neither key is actually derivable from the other. When they are created, they are generated together from a common base (not just the public key from the private key). But typically, the file that stores the "private key" actually contains a bit more information than just the private key. For example, in PKCS #1 RSA private key format ( https://tools.ietf.org/html/rfc3447#appendix-A.1.2 ), the file technically contains the entire public key too. So in short, you technically can't get the public key from the private key or vice versa, but the file that contains the private key can hold more than just the private key alone, making it possible to retrieve the public key from it.

Python is an interpreted text based general purpose programming language, which is a key requisite of the 7-10 Digital Technologies Curriculum. Python is also the only professional programming language that was designed with beginners in mind, it is intuitive and easy to use What are the student outcomes? Students learn about core concepts of programming: branching, iteration and functions. They apply these to create four applications which perform the following: Simulation of an intelligent conversation User Authentication using passwords and/or secret questions A game where user guesses a number and the program informs the user of his accuracy over time A program that encrypts and decrypts messages using the Caesar Cypher What is the educational approach of the course? The course explicitly teaches the concepts such as loops or functions, performing several examples in the interactive shell. Then these concepts are employed to create a computer program these programs progress in their level of difficulty, eventually performing complex tasks like encryption Beyond the concepts and applications students will also learn the following skills: Creating algorithms which can be represented in the form of flowcharts, which are in turn easy to translate to code.

Zhihao Yuan: Fun with C11 generic selection expression
 
01:09:27
One must be really brave to talk about a C-only language feature on a C++ conference, especially when the feature is considered as a parody to some well established, very successful C++ ones. Of course, I'm not that brave. This lecture will firstly introduce C11 generic selection expression to people who are not familiar with it, then primarily focus on the possible uses of such a feature in C++, see how it helps C++ generic programming and meta programming (!!), and compare it to some future C++ language additions.

Implementing Spark like system in Haskell by Yogesh Sajanikar
 
01:17:39
The session will present design and implementation of Hspark. A library that implements a framework to enable running a distributed map-reduce job over a set of nodes. The session will also showcase an extensible DSL to specify distributed map-reduce job. The session will focus mainly on Creation of DSL (Specification) for map reduce. The DSL is similar (actually based on) Apache Spark Translation of DSL into scheduling the jobs across the nodes, and Executing and handling failures. Current implementation of hspark is at https://github.com/yogeshsajanikar/hspark and implements first two points mentioned above. Currently, I am trying to enforce it with separation of execution framework so that failures can be handled correctly. Note that this project was implemented as a part of course project for CS240H at Stanford.

Greatest common divisor - code for Euclid's algorithm
 
14:15
This is the code for the Euclid's Algorithm to find the GCD (Greatest Common Divisor) of two numbers. The code is written in Java. There are three variations shown here: 1) Recursive GCD 2) Iterative GCD 3) Binary GCD The GCD of two given numbers is defined as the largest possible number which divides both the numbers with no remainder. The GCD of a number is also sometimes called Highest Common Factor. Do check out the other two videos on the proof of the algorithm (https://youtu.be/B5HKW99AvV0) and an exciting question (https://youtu.be/D-DYtUmRMa4)!

Modular arithmetic with Fermat and Euler | Data Structures in Mathematics Math Foundations 197
 
37:21
There are two important theorems that make the job of understanding powers in modular arithmetic much simpler. These go back to Fermat and Euler. We apply these to the nice problem of deciding z mod 13. Fermat's result helps us understand powers to a prime modulus. Euler's result relies on understanding the interesting Euler phi function, and is a generalization of Fermat's. As usual we like to illustrate theorems with explicit examples. Screenshot PDFs for my videos are available at the website http://wildegg.com. These give you a concise overview of the contents of each lecture. Great for review, study and summary.

Famous UNCRACKED Codes That STILL Exist!
 
12:26
Check out these famous uncracked codes that still exist! From secret riddles to unsolved mysteries, this top 10 list contains cryptography that's still unexplained today! Subscribe For New Videos! http://goo.gl/UIzLeB Watch our "Most CRAZY Things Ancient Egyptians Did!" video here: https://youtu.be/T0zERiMJFQo Watch our "Most CRAZY Things Ancient Greeks Did!" video here: https://youtu.be/-JkhVvn_dow Watch our "REAL Evidence That Aliens EXIST!" video here: https://youtu.be/dtwJT2eilx0 10. Chinese Gold Bar Cipher In 1933, General Wang in Shanghai, China, allegedly received seven gold bars. These gold bars appear to represent metal certificates related to a bank deposit with a U.S. Bank. The gold bars themselves have pictures, Chinese writing, some form of script writing, and cryptograms in Latin letters. Not surprisingly, experts debate concerning the validity of the claim for the deposit. It may help to resolve the dispute if someone can decipher the cryptograms on the bars. Someone translated the Chinese writing, which discusses a transaction in excess of $300,000,000. It also refers to these gold bars, which weigh a total of 1.8 kilograms. The rest remains a mystery. 9. D’agapeyeff Cipher The D’Agapeyeff cipher is an as-yet unbroken cipher that appears in the first edition of Codes and Ciphers, an elementary book on cryptography published by the Russian-born English cartographer Alexander D’Agapeyeff in 1939. Offered as a “challenge cipher” at the end of the book, it was not included in later editions. D’Agapeyeff supposedly admitted later to having forgotten how he had encrypted it. Some argue that the failure of all attempts at decryption is due to D’Agapeyeff incorrectly encrypting the original text. However, it has also been argued that the cipher may still be successfully attacked using computational methods such as genetic algorithms. Whatever those are. 8. The Beale Ciphers If this next one isn’t a hoax then the person who solves it could become very, very rich. This question of authenticity has bothered cryptoanalysts ever since these ciphers first appeared in an 1885 pamphlet called The Beale Papers, which recounts a fantastic story of buried treasure. According to the pamphlet, a man named Thomas Jefferson Beale, a man no one has proven even existed, discovered gold during an 1816 expedition into the American West. The treasure, as the story goes, was then transported to Bedford County, Virginia, and buried. The gold's secret location was allegedly provided by three cryptograms, of which one was already cracked. Unfortunately, the cracked code only detailed the type of treasure there and not a specific location. To find out anything more specific would involve cracking the two other ciphers. The problem is that figuring it out requires comparing them to unknown historical texts. The decrypted cipher, for example, used the Declaration of Independence. The first number, 115, corresponds with the first letter of the 115th word in the Declaration: "instituted." That means 115 stands for "I." So what are the translation texts for the other two ciphers? No one knows, and they may very well not exist at all. There are also questions over whether the other ciphers may just be unintelligible, as if the whole thing was made up by the pamphlet's author decades after the gold was supposed to have been discovered. 7. Dorabella In 1897, a 40-year-old composer named Edward Elgar sent an encrypted letter to 23-year-old Dora Penny, the stepdaughter of one of his friends. Why he sent it is part of the mystery and can only be answered if anyone ever cracks the code. To figure it out would involve deciphering 87 characters all made of strings of semi-circles oriented in different directions. Attempts at translating the cipher yielded a message just short of gibberish. Experts say that shorter ciphers are always harder to solve. Another theory has it that the code is an example of a distinct private language shared only between Penny and Elgar. If that's the case, then solving it may be simply impossible, since no one but them would understand the references. In 2016, a police officer in Cleveland believes he’s cracked at least part of the code, revealing a line of melody. Inspector Mark Pitt read 100 books on the Dorabella Cipher; he hopes to write one on his discoveries. Whether or not that’s really the meaning, though, remains to be seen.
