Bitcoin Q&A: How long until mainstream adoption?
 
05:58
How long until mainstream adoption? Previous revolutions in money. In the mid 90s, you still couldn't pay with a credit card in many places. I predict it will take 15-20 years for mainstream adoption of Bitcoin. We are in a race because governments around the world are trying to ban cash and force us to adopt a different sort of digital currency with complete surveillance, where they can flip and switch and you will no longer exist as a person if you doing anything they consider radical. Adoption patterns and the Gini coefficient. The ownership of Bitcoin is not as diverse as it should be, primarily because of the way it grew. But people who got in early and took the risk have been enormously rewarded; no one's coming to bail out Bitcoin.

The Science of Secrecy from Ancient Egypt to Quantum Cryptography (1999)
 
54:42
Simon Lehna Singh MBE (born 19 September 1964) is a British popular science author whose works largely contain a strong mathematical element. His written works include Fermat's Last Theorem (in the United States titled Fermat's Enigma: The Epic Quest to Solve the World's Greatest Mathematical Problem),[2][3] The Code Book[4] (about cryptography and its history), Big Bang[5] (about the Big Bang theory and the origins of the universe), Trick or Treatment? Alternative Medicine on Trial[6] (about complementary and alternative medicine, co-written by Edzard Ernst) and The Simpsons and Their Mathematical Secrets (about mathematical ideas and theorems hidden in episodes of The Simpsons and Futurama).[7] In 2012 Singh founded the Good Thinking Society.[8] Singh has also produced documentaries and works for television to accompany his books, is a trustee of NESTA, the National Museum of Science and Industry and co-founded the Undergraduate Ambassadors Scheme. Singh's parents emigrated from Punjab, India to Britain in 1950. He is the youngest of three brothers, his eldest brother being Tom Singh, the founder of the UK New Look chain of stores. Singh grew up in Wellington, Somerset, attending Wellington School, and went on to Imperial College London, where he studied physics. He was active in the student union, becoming President of the Royal College of Science Union.[9] Later he completed a PhD degree in particle physics at Emmanuel College, Cambridge and at CERN, Geneva. In 1983, he was part of the UA2 experiment in CERN.[11] In 1987, Singh taught science at The Doon School, the independent all-boys' boarding school in India.[12] In 1990 Singh returned to England and joined the BBC's Science and Features Department, where he was a producer and director working on programmes such as Tomorrow's World and Horizon. Singh was introduced to Richard Wiseman through their collaboration onTomorrow's World. At Wiseman's suggestion, Singh directed a segment about politicians lying in different mediums, and getting the public's opinion on if the person was lying or not. After attending some of Wiseman's lectures, Singh came up with the idea to create a show together, and Theatre of Science was born. It was a way to deliver science to normal people in an entertaining manner. Richard Wiseman has influenced Singh in such a way that Singh states: My writing initially was about pure science but a lot of my research now has been inspired by his desire to debunk things such as the paranormal – we both hate psychics, mediums, pseudoscience in general.[13] Singh directed his BAFTA award-winning documentary about the world's most notorious mathematical problem entitled "Fermat's Last Theorem" in 1996. The film was memorable for its opening shot of a middle-aged mathematician, Andrew Wiles, holding back tears as he recalled the moment when he finally realised how to resolve the fundamental error in his proof of Fermat's Last Theorem. The documentary was originally transmitted in October 1997 as an edition of the BBC Horizon series. It was also aired in America as part of the NOVA series. The Proof, as it was re-titled, was nominated for an Emmy Award. The story of this celebrated mathematical problem was also the subject of Singh's first book, Fermat's last theorem. In 1997, he began working on his second book, The Code Book, a history of codes and codebreaking. As well as explaining the science of codes and describing the impact of cryptography on history, the book also contends that cryptography is more important today than ever before. The Code Book has resulted in a return to television for him. He presented The Science of Secrecy, a five-part series for Channel 4. The stories in the series range from the cipher that sealed the fate of Mary, Queen of Scots, to the coded Zimmermann Telegram that changed the course of the First World War. Other programmes discuss how two great 19th century geniuses raced to decipher Egyptian hieroglyphs and how modern encryption can guarantee privacy on the Internet. https://en.wikipedia.org/wiki/Simon_Singh Image: Sam Hughes [CC BY 2.0 (http://creativecommons.org/licenses/by/2.0)], via Wikimedia Commons

It's probably my favorite C++11 feature and it's gotten even better with C++14. But when I talk to other developers about constexpr they seem puzzled. What sorts of useful computations can the compiler possibly do before runtime? I'd like to take this session to explore some of the capabilities that constexpr brings to the table. We'll look at compile-time parsing, floating-point computations, and containers. We'll also talk about motivations for computing these at compile time.

King uses the photomultiplier and the oscilloscope to demonstrate that light shows particle behavior. He describes the photmultiplier, demonstrates amplification, and discusses the reasoning required to understand the final outcome." Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). https://en.wikipedia.org/wiki/Photon Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ A photon is an elementary particle, the quantum of the electromagnetic field including electromagnetic radiation such as light, and the force carrier for the electromagnetic force (even when static via virtual photons). The photon has zero rest mass and always moves at the speed of light within a vacuum. Like all elementary particles, photons are currently best explained by quantum mechanics and exhibit wave–particle duality, exhibiting properties of both waves and particles. For example, a single photon may be refracted by a lens and exhibit wave interference with itself, and it can behave as a particle with definite and finite measurable position and momentum. The photon's wave and quanta qualities are two observable aspects of a single phenomenon, and cannot be described by any mechanical model; a representation of this dual property of light, which assumes certain points on the wavefront to be the seat of the energy, is not possible. The quanta in a light wave cannot be spatially localized. Some defined physical parameters of a photon are listed. The modern concept of the photon was developed gradually by Albert Einstein in the early 20th century to explain experimental observations that did not fit the classical wave model of light. The benefit of the photon model was that it accounted for the frequency dependence of light's energy, and explained the ability of matter and electromagnetic radiation to be in thermal equilibrium. The photon model accounted for anomalous observations, including the properties of black-body radiation, that others (notably Max Planck) had tried to explain using semiclassical models. In that model, light was described by Maxwell's equations, but material objects emitted and absorbed light in quantized amounts (i.e., they change energy only by certain particular discrete amounts). Although these semiclassical models contributed to the development of quantum mechanics, many further experiments beginning with the phenomenon of Compton scattering of single photons by electrons, validated Einstein's hypothesis that light itself is quantized. In 1926 the optical physicist Frithiof Wolfers and the chemist Gilbert N. Lewis coined the name photon for these particles. After Arthur H. Compton won the Nobel Prize in 1927 for his scattering studies, most scientists accepted that light quanta have an independent existence, and the term photon was accepted. In the Standard Model of particle physics, photons and other elementary particles are described as a necessary consequence of physical laws having a certain symmetry at every point in spacetime. The intrinsic properties of particles, such as charge, mass and spin, are determined by this gauge symmetry. The photon concept has led to momentous advances in experimental and theoretical physics, including lasers, Bose–Einstein condensation, quantum field theory, and the probabilistic interpretation of quantum mechanics. It has been applied to photochemistry, high-resolution microscopy, and measurements of molecular distances. Recently, photons have been studied as elements of quantum computers, and for applications in optical imaging and optical communication such as quantum cryptography...

Designing Quality APIs (Cloud Next '18)
 
40:51
A quality API has to satisfy demands of ease of use, ease of learning, stability in the face of change, and compatibility with client tools and technologies. Adding to the challenge is the fact that there are two irreconcilable conceptual models for API designs — RPC and REST. Come and learn how to think about the RPC/REST dichotomy and understand the problems and solutions of quality API design—regardless of the model chosen. We will also present some of the major GCP services and tools that are used to implement APIs in both models.

3D Graphics: Crash Course Computer Science #27
 
12:41
Today we’re going to discuss how 3D graphics are created and then rendered for a 2D screen. From polygon count and meshes, to lighting and texturing, there are a lot of considerations in building the 3D objects we see in our movies and video games, but then displaying these 3D objects of a 2D surface adds an additional number of challenges. So we’ll talk about some of the reasons you see occasional glitches in your video games as well as the reason a dedicated graphics processing unit, or GPU, was needed to meet the increasing demand for more and more complex graphics.

Worse than Useless: Financial Surveillance
 
21:10
In this talk, Andreas makes a connection between medical pseudoscience and modern financial totalitarian surveillance, as practiced by banks and state intelligence agencies. He explores the hidden externalities and moral hazards inherent in KYC/AML policies, disconnecting whole countries and even continents from the world economy. Why is it common sense that money laundering is the fundamental business of fully-licensed, regulated banks? Who runs the real "dark net"? He urges that before people try to fix things they should first be sure they're not making it worse.

Alex Martelli, ""The Tower of Abstraction", PyBay2016
 
51:27
Description Abstraction is a powerful servant, but a dangerous master. We code, design, think, debug ... on a tower of abstractions. Spolsky's Law tells us that "All abstractions leak". This talk explores why they leak, why that's often a problem, what to do about it; I also cover why sometimes abstractions SHOULD "leak", and how best to produce and consume abstraction layers. Bio Author of "Python in a Nutshell", co-author of "Python Cookbook", PSF Fellow, frequent speaker at Python conferences, prolific contributor to StackOverflow, and winner of the 2006 Frank Willison Memorial Award for contributions to Python, Alex currently leads "1:many tech support" for Google Cloud Platform. He's married to Anna Ravenscroft, his co-author in the "Cookbook" 2nd edition and "Nutshell" 3rd edition, also a PSF Fellow, and also a winner of the Frank Willison Memorial Award, in 2013. https://speakerdeck.com/pybay2016/alex-martelli-the-tower-of-abstraction

Quantum Computing for Computer Scientists
 
01:28:23
This talk discards hand-wavy pop-science metaphors and answers a simple question: from a computer science perspective, how can a quantum computer outperform a classical computer? Attendees will learn the following: - Representing computation with basic linear algebra (matrices and vectors) - The computational workings of qbits, superposition, and quantum logic gates - Solving the Deutsch oracle problem: the simplest problem where a quantum computer outperforms classical methods - Bonus topics: quantum entanglement and teleportation The talk concludes with a live demonstration of quantum entanglement on a real-world quantum computer, and a demo of the Deutsch oracle problem implemented in Q# with the Microsoft Quantum Development Kit. This talk assumes no prerequisite knowledge, although comfort with basic linear algebra (matrices, vectors, matrix multiplication) will ease understanding.

CGC Grading Curve
 
04:57
How does CGC grade comics? grading is subjective and not an exact science. CGC gives you an opinion on your book and that opinion can change if the book was to be submitted multiple times. Buy the book not the grade. better yet buy the book that is undergraded

Temple Talk Radio: Parashat Behar & the Sanctity of the Land of Israel
 
46:12
Israel, Iran & the Winds of War The Deadly Danger of Hubris, Lag B'Omer & the Mysterious Fate of Rabbi Akiva's Students This week's edition of Temple Talk features Yitzchak Reuven alone in the studio as Rabbi Richman is en route to the USA where he will be speaking next week in Texas. But don't touch that dial - Yitzchak has some important things to share! Parashat Behar presents G-d's first formal introduction of the incredible land of Israel to the children of Israel, as G-d calls upon Israel to take very special care of the sacred land. Meanwhile, three thousand five hundred years later, Israel is defending her precious land, taking out Iranian arsenals in Syria, intended to be used against Israel, and the fabled Israeli Mossad manages to pull off the heist of the century, walking out of Iran with a truckload of top secret documents exposing the extent of Iran's deadly nuclear intentions.

Papers We Love - QCon NYC Edition | Gwen Shapira on Realtime Data Processing at Facebook
 
21:54
Meetup: http://bit.ly/2uSFBlB Paper: http://bit.ly/2u2Nwj2 Slides: http://bit.ly/2w0VBSI Audio: http://bit.ly/2wgaqju ---------------------------------------------------------------------------------------- Sponsored by Two Sigma (@twosigma) and QCon NYC ---------------------------------------------------------------------------------------- Description ------------------ Realtime data processing powers many use cases at Facebook, including realtime reporting of the aggregated, anonymized voice of Facebook users, analytics for mobile applications, and insights for Facebook page administrators. Many companies have developed their own systems; we have a realtime data processing ecosystem at Facebook that handles hundreds of Gigabytes per second across hundreds of data pipelines. Many decisions must be made while designing a realtime stream processing system. In this paper, we identify five important design decisions that affect their ease of use, performance, fault tolerance, scalability, and correctness. We compare the alternative choices for each decision and contrast what we built at Facebook to other published systems. Our main decision was targeting seconds of latency, not milliseconds. Seconds is fast enough for all of the use cases we support and it allows us to use a persistent message bus for data transport. This data transport mechanism then paved the way for fault tolerance, scalability, and multiple options for correctness in our stream processing systems Puma, Swift, and Stylus... Bio ----- Gwen Shapira is a product manager at Confluent. She has 15 years of experience working with code and customers to build scalable data architectures, integrating relational and big data technologies. Gwen is the author of Kafka - The Definitive Guide and Hadoop Application Architectures, and a frequent presenter at industry conferences. Gwen is a PMC member on the Apache Kafka project and committer on Apache Sqoop. When Gwen isn't building data pipelines or thinking up new features, you can find her pedaling on her bike exploring the roads and trails of California, and beyond.

Crypto Millionaire: What Is Ethereum?
 
01:30
What Is Ethereum? In short, ethereum wants to be a 'World Computer' that would decentralize – and some would argue, democratize – the existing client-server model. With ethereum, servers and clouds are replaced by thousands of so-called "nodes" run by volunteers from across the globe (thus forming a "world computer"). The vision is that ethereum would enable this same functionality to people anywhere around the world, enabling them to compete to offer services on top of this infrastructure. Welcome to to CryptoMillionaire, I'm Mo Ismail. Entrepreneur, Investor and some call me the Modern Day Renaissance man (Because I like to put my hands in everything!)  I started investing at a very young age, 19 years old to be exact, and over the past 10 years I have turned just under $10,000 into over $1.6 million trading on the Stock Market, Forex, and most of all Crypto-Currency. I am now 30 years old, and many consider me to be financially independent. I created CryptoMillionaire with the aim to educate, empower, and engage others to follow a similar path. Cryptocurrency has the potential to provide the opportunity of financial independence to early adapters of Blockchain technology, however as it is still in its early stages, not many people necessarily understand what it is, and how it works, thus making the common investor intimidated of this emerging new "Hot" market. I am here to change that, and I am here to provide you with guidance and information on how to start investing in the Crypto-Currency market. www.cryptomillionaire.me
