Key Exchange
 
03:29
This clip from the 2008 Royal Institution Christmas Lectures shows a simple demonstration of how two people can agree on a secret key, even though all of their communications are carried out in public. In the electronic world, secret key exchange allows computers to communicate securely, and is used, for example, when you give your credit card information to an on-line shop. You can watch the 2008 Royal Institution Christmas Lectures in full at: http://research.microsoft.com/~cmbishop or by visiting the Royal Institution web site. There is a dedicated web site to accompany the 2008 Christmas Lectures, with ten interactive games as well as downloadable PDF instructions for experiments which can be conducted at home or at school: http://www.rigb.org/christmaslectures08

Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics. In these tutorials, we will cover a range of topics, some which include: independent events, dependent probability, combinatorics, hypothesis testing, descriptive statistics, random variables, probability distributions, regression, and inferential statistics. So buckle up and hop on for a wild ride. We bet you're going to be challenged AND love it! About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content. For free. For everyone.

Es ging darum, Zuhörern, die sonst nichts mit Mathe am Hut haben, anhand eines Beispiels eine Vorstellung davon zu vermitteln, welche Fragen Mathematiker eigentlich beschäftigen.

In billions of years, the sun will expand to engulf the Earth and life on this planet will become impossible. But there are plenty of ways it could end much sooner! Subscribe for regular science videos: http://bit.ly/RiSubscRibe Join Lewis Dartnell and a panel of scientists and disaster experts including Rosalind Eggo, Vinay Gupta and Hugh Lewis for a discussion on how to cancel the apocalypse. Lewis Dartnell is a research scientist, presenter and author. His most recent book, The Knowledge, looks at the essential information and skills needed to rebuild after an apocalypse. Rosalind Eggo is a mathematical modeller at the London School of Hygiene and Tropical Medicine. She builds mathematical and computational models to explain how diseases spread through populations, with the aim of designing interventions that can prevent that spread. She has worked on models to understand the transmission of Ebola, influenza, other respiratory viruses and Zika. Vinay Gupta is a technologist and policy analyst with a particular interest in how specific technologies can close or create new avenues for decision makers. This interest has taken him through cryptography, energy policy, defence, security, resilience and disaster management arenas. He is the founder of Hexayurt.Capital, a fund which invests in creating the Internet of Agreements™. He is known for his work on the hexayurt, a public domain disaster relief shelter designed to be build from commonly-available materials, and with Ethereum, a distributed network designed to handle smart contracts. Hugh Lewis is a Senior Lecturer in Aerospace Engineering at the University of Southampton, author of the space debris evolutionary model DAMAGE and he lead the Astronautics Research Group’s space debris and space situational awareness activities. He is also a member of the UK's delegation to the UN Space Mission Planning Advisory Group, a roundtable of experts who discuss how to prepare an international response to near Earth objects (ie asteroids).

When we consider the great empires of the past, we should learn the lessons of history. One of the major causes of the decline of Rome was the disintegration of family.

From Bitcoin To Hashgraph (Documentary) Hidden Secrets Of Money Episode 8
 
01:14:26
Bonus Features: http://www.hiddensecretsofmoney.com Today, mankind stands at a crossroads, and the path that humanity chooses may have a greater impact on our freedom and prosperity than any event in history. In 2008 a new technology was introduced that is so important that its destiny, and the destiny of mankind are inextricably linked. It is so powerful that if captured and controlled, it could enslave all of humanity. But if allowed to remain free and flourish - it could foster unimaginable levels of peace and prosperity. It has the power to replace all financial systems globally, to supplant ninety percent of Wall St, and to provide some functions of government. It has no agenda. It's always fair and impartial. It can not be manipulated, subverted, corrupted or cheated. And - it inverts the power structure and places control of one's destiny in the hands of the individual. In the future, when we look back at the 2.6 million-year timeline of human development and the major turning points that led to modern civilization - the creation of farming, the domestication of animals, the invention of the wheel, the harnessing of electricity and the splitting of the atom - the sixty year development of computers, the internet and this new technology will be looked upon as a single event...a turning point that will change the course of human history. It's called Full Consensus Distibuted Ledger Technology, and so far its major use has been for cryptocurrencies such as Bitcoin....but its potential goes far, far beyond that. The Crypto Revolution: From Bitcoin to Hashgraph is our latest episode of Hidden Secrets of Money. It’s about the evolution of cryptocurrencies and full consensus distributed ledger technology, and how they will change our world. I believe that this video is by far the easiest way for the average person to gain an understanding of what cryptocurrencies are and how they work, but more importantly, the immense power of full consensus distributed ledger technology and the impact it will have on our daily lives. I have an absolute passion for monetary history and economics, and I love teaching them. Cryptocurrencies are our future, and there is no escaping it… this is the way everything will be done from now on. But, we now stand at a crucial turning point in history. Full consensus ledgers such as Blockchain and Hashgraph have the power to enslave us, or free us… it all depends on how we choose to use them. If we choose to support centralized versions issued by governments and the financial sector we will be granting them more control over our daily lives. Politicians and bureaucrats will be able raise taxes instantly, whenever they want, on every dollar you make as you make them, and every dollar you spend as you spend them. If they think the economy needs stimulating they'll be able to enforce huge negative interest rates, effectively punishing you for not spending everything you earn before you earn it. They'll be able to decide where you can go and where you can’t, what you can buy and what you can’t, and what you can do and whatever they decide you can’t do… and if they don't like you, they can just disconnect you from the monetary system. So, will the monetary system become fully distributed and help to free mankind, or will it be centralized and enslave us? The choice is in front of us right now, and our decisions will create our future. I believe that this will be a binary outcome, there is no middle ground, it will either be one future or the other. The question is, will it be the future we want? Or the future they want? I’m a precious metals dealer and one thing I’ve learned is that gold, silver, and now free market decentralized cryptocurrencies, represent freedom. Because of this knowledge I started investing in crypto currencies long ago and also became one of the first precious metals dealers to accept bitcoin as payment for gold and silver. I would really appreciate it if you could share this video with everyone you know. I think it’s very important that as many people as possible find out about the changes to the global monetary system that are happening right now… nothing will affect us more, and everyone’s future depends on it.

Dash: Evan Duffield Presentation Virtual Crypto Money Expo Dec 2014 = C14E02
 
14:38
Evan Duffield Presentation Virtual Crypto Money Expo Dec 2014 Dash is DigitalCash Dash is a decentralized cryptographic currency that works similar to Bitcoin, but fixes many of Bitcoin's problems. Dash's InstantX technology makes transactions almost instant, meaning it is suitable for in-person trades and point-of-sale purchases. Not only that, but Dash is truly private, meaning that nobody can mine the blockchain to find details of your purchases or financial history. You wouldn't advertise your credit card statement--why advertise your crypto purchases? Dash is built from Bitcoin's core code, meaning that it remains compatible with systems that are already designed to work with Bitcoin. The creator of Dash, Evan Duffield, works with a "core team" of almost 20 people to continually improve the Dash code and ecosystem. Since Dash implemented its self-funding mechanism, a number of new developers have begun working on various aspects of the project as well, including retail point-of-sale and vending machine integration. Dash's masternodes enable investors to earn a 10+% annual return on investment while performing vital services for the network. Masternodes power both the privacy and instant transaction features of Dash. Not only that, but masternode owners are able to vote on which projects will receive Dash's monthly self-generated budget funding. Dash's budget system provides tens of thousands of dollars in recurring funds, every month, which masternode owners allocate to projects designed to improve the Dash ecosystem. https://www.dash.org

The Third Industrial Revolution: A Radical New Sharing Economy
 
01:44:59
The global economy is in crisis. The exponential exhaustion of natural resources, declining productivity, slow growth, rising unemployment, and steep inequality, forces us to rethink our economic models. Where do we go from here? In this feature-length documentary, social and economic theorist Jeremy Rifkin lays out a road map to usher in a new economic system. A Third Industrial Revolution is unfolding with the convergence of three pivotal technologies: an ultra-fast 5G communication internet, a renewable energy internet, and a driverless mobility internet, all connected to the Internet of Things embedded across society and the environment. This 21st century smart digital infrastructure is giving rise to a radical new sharing economy that is transforming the way we manage, power and move economic life. But with climate change now ravaging the planet, it needs to happen fast. Change of this magnitude requires political will and a profound ideological shift.

DEF CON 21 - Jacob Thompson - C R E A M Cache Rules Evidently Ambiguous Misunderstood
 
23:25
C.R.E.A.M. Cache Rules Evidently Ambiguous, Misunderstood JACOB THOMPSON Common wisdom dictates that web applications serving sensitive data must use an encrypted connection (i.e., HTTPS) to protect data in transit. Once served, that same sensitive data must be protected at rest, either through encryption, or more appropriately by not storing the sensitive data on disk at all. In the past, web browser disk caching policies maintained a distinction between HTTP and HTTPS requests, typically refusing to cache HTTPS requests. With today's bandwidth- and performance-hungry AJAX and HTML5 applications, most modern browsers treat all content (including HTTPS) as safe to cache to disk unless explicitly restricted by the server. This silent "shift" of responsibility from browser to web-application server has eluded both secure web-application and safe-browsing paradigms, leaving consumers exposed. Even OWASP recommended guidelines for creating secure web applications are wrong regarding this topic [1]. We tested over thirty sites that provide personal financial, health, and insurance-related information to determine what, if any, sensitive information was cached to disk and the results were surprising. Over 70% of tested sites cached sensitive information, ranging from account balances to bank-check images, bank statements, and full credit reports. We will discuss not only the technical details of these caching vulnerabilities, but also the history behind the "shift" in cache policy responsibility, the breakdown in conventional wisdom concerning web application and web-browser security policies, the ramifications of caching PII to disk, and the potential widespread violation of most compliance standards, including PCI, HIPAA, SOX, and government standards such as FIPS or Common Criteria. Jacob Thompson is a security analyst at Independent Security Evaluators, a Baltimore, Maryland, company specializing in high-end, custom security assessments of computer hardware and software products. Jacob holds an M.S. in Computer Science from the University of Maryland, Baltimore County. His primary security interests include analyzing commercial software products for design flaws and other vulnerabilities, reverse engineering, and cryptography. Prior to joining ISE, Jacob served as a Computer Science teaching assistant and briefly worked as an intern software engineer developing desktop and embedded applications for process control systems.

Attack Tree Analysis   understanding and modelling threats
 
45:44
In today's increasingly interconnected world, system hazards are more likely than ever to originate from deliberate attacks, such as hacking and malware. Using the example of how an attacker could gain access to on-board systems in a car by hacking into the entertainment system, this webinar will show how attack tree analysis, a modified form of fault tree analysis, can be used to predict the frequency of a threat due to attacks on a system and the failure of defensive measures. We will also demonstrate how attack tree analysis can take into account the impact of a successful attack on factors such as cost and safety, as well as the cost and difficulty incurred by the attacker.
