Bitcoin Textbook, Brain Books, Post-Quantum Crypto, and Amazon's Game Engine

  1. Princeton Bitcoin Book (PDF) — The Coursera course accompanying this book had 30,000 students in its first version, and it was a success based on engagement and end-of-course feedback. Large introduction to Bitcoin from Princeton. (via Cory Doctorow)
  2. A Quartet of Complementary Brain Books (Vaughan Bell) — The books have been chosen to complement each other and the idea is that if you read all four, you should have a solid grounding in modern cognitive neuroscience and beyond.
  3. NIST Report on Post-Quantum Cryptography (PDF) — in case you missed it, “post-quantum crypto” is “existing crypto relies on how hard it is to find the prime factors of large numbers, of which we suspect quantum computers may make a mockery. Wut to do?” The goal of post-quantum cryptography (also called quantum-resistant cryptography) is to develop cryptographic systems that are secure against both quantum and classical computers, and can interoperate with existing communications protocols and networks.
  4. Amazon Lumberyarda free, cross-platform, 3D game engine for you to create the highest-quality games, connect your games to the vast compute and storage of the AWS Cloud, and engage fans on Twitch. From Amazon.

Bitcoin Resolution, Malware Analysis, Website Screw-Ups, and Dronecode.

  1. The Resolution of the Bitcoin ExperimentIf you had never heard about Bitcoin before, would you care about a payments network that: Couldn’t move your existing money; Had wildly unpredictable fees that were high and rising fast; Allowed buyers to take back payments they’d made after walking out of shops, by simply pressing a button (if you aren’t aware of this “feature” that’s because Bitcoin was only just changed to allow it); Is suffering large backlogs and flaky payments; … which is controlled by China; … and in which the companies and people building it were in open civil war?
  2. Malware Analysis Repository the materials as developed and used by RPISEC to teach Malware Analysis at Rensselaer Polytechnic Institute in Fall 2015.
  3. How Websites Screw Up Experiences (Troy Hunt) — they’re mostly signs of a to-the-death business model.
  4. Dronecode Moves Forward — Linux Foundation’s Dronecode project has 51 members, is used commercially, and has technical working groups looking at camera and gimbal controls; airspace management; and hardware/software interfaces.

Bitcoin Software Choke, IoT Chokes, Dynabook History, and Fault Tree Analysis

  1. Core Bitcoin Devs LeaveAccording to a press release put out by Company 0 LLC, formed by former bitcoin developers, there are a few external entities that fund the actual development of the bitcoin cryptocurrency, forming a power-group that is in sole command of the direction the currency takes. These developers say that this group limits outside input in the currency’s governance, cherry-picks only options favorable for their own interests, and generally ignores the developers’ and community’s best interests.
  2. Internet of Proprietary Things — wonderfully accessible list of things we don’t have: Because companies can enforce anti-competitive behavior this way, there’s a litany of things that just don’t exist, even though they would make life easier for consumers in significant ways. You can’t have custom software for your cochlear implant, or your programmable thermostat, or your computer-enabled Barbie doll. An auto-repair shop can’t design a better diagnostic system that interfaces with a car’s computers. Capturing all the value you create, versus creating more value than you capture.
  3. Tracing the Dynabooka historical study of the Dynabook project and vision, which began as a blue-sky project to define personal and educational computing at Xerox PARC in the 1970s. It traces the idea through the three intervening decades, noting the transformations that occur as the vision and its artifacts meet varying contexts. (via Bret Victor)

Machine Poetry, Robo Script Kiddies, Big Data of Love, and Virtual Currency and the Nation State

  1. How Machines Write PoetryHarmon would love to have writers or other experts judge FIGURE8’s work, too. Her online subjects tended to rate the similes better if they were obvious. “The snow continued like a heavy rain” got high scores, for example, even though Harmon thought this was quite a bad effort on FIGURE8’s part. She preferred “the snow falls like a dead cat,” which got only middling ratings from humans. “They might have been cat lovers,” she says. FIGURE8 (PDF) system generates figurative language.
  2. The Decisions the Pentagon Wants to Leave to Robots“You cannot have a human operator operating at human speed fighting back at determined cyber tech,” Work said. “You are going to need have a learning machine that does that.” I for one welcome our new robot script kiddie overlords.
  3. Love in the Age of Big DataOver decades, John has observed more than 3,000 couples longitudinally, discovering patterns of argument and subtle behaviors that can predict whether a couple would be happily partnered years later or unhappy or divorced. Turns out, “don’t be a jerk” is good advice for marriages, too. (via Cory Doctorow)

Telepresent Axeman, Toxic Workers, Analysis Code, and Cryptocurrency Attacks

  1. Axe-Wielding Robot w/Telepresence (YouTube) — graphic robot-on-wall action at 2m30s. (via IEEE)
  2. Toxic Workers (PDF) — In comparing the two costs, even if a firm could replace an average worker with one who performs in the top 1%, it would still be better off by replacing a toxic worker with an average worker by more than two-to-one. Harvard Business School research. (via Fortune)
  3. Replacing Sawzall (Google) — At Google, most Sawzall analysis has been replaced by Go […] we’ve developed a set of Go libraries that we call Lingo (for Logs in Go). Lingo includes a table aggregation library that brings the powerful features of Sawzall aggregation tables to Go, using reflection to support user-defined types for table keys and values. It also provides default behavior for setting up and running a MapReduce that reads data from the logs proxy. The result is that Lingo analysis code is often as concise and simple as (and sometimes simpler than) the Sawzall equivalent.

World SF, Digital Currency Scholarships, Project Management, and Glass 3D Printing

  1. The Apex Book of World SF 4 (Amazon) — if SF invents the future by shaping and directing our imagination, and if you believe that non-American cultures will ascend over time, then it behooves you to sample this collection of SF from beyond the usual. (via Cory Doctorow)
  2. Diversity Scholarships Available — to Digital Consensus 2015, a conference on digital currency. Apply or tell someone who is eligible.
  3. Making Huge Projects Work (Amy Hoy) — the description of her workflow for modest and monster projects was useful to me, and may be to you as well. I think the real question is “where do we get an Alex of our own?” [Note: swearing]

Consumer Exoskeleton, Bitcoin Trends, p2p Sockets, and Plain Government Comms

  1. ReWalk Robotics Exoskeleton — first exoskeleton for the paralyzed to receive regulatory approval; 66 bought so far, 11 with reimbursement from insurance. The software upgrades for the ReWalk 6.0 provide a smoother walking gait (with less of a soldier-like marching step), an easier stopping mechanism, and a much-improved mode for ascending and descending stairs. The user wears a wristwatch-like controller to switch the suit between sit, stand, walk, and stair modes. How long until a cheaper version hits the market, but you don’t always get to control where it takes you if there’s a sale on featuring brands you love? (via IEEE)
  2. Bitcoin Trends in First Half of 201594% increase in monthly transactions over the past year. 47% of Coinbase wallet holders are now from countries outside the U.S.
  3. Socket.io p2pan easy and reliable way to set up a WebRTC connection between peers and communicate using the socket.io-protocol.

Our future sits at the intersection of artificial intelligence and blockchain

The O'Reilly Radar Podcast: Steve Omohundro on AI, cryptocurrencies, and ensuring a safe future for humanity.

Ron_Cogswell_Flickr

Subscribe to the O’Reilly Radar Podcast to track the technologies and people that will shape our world in the years to come.

I met up with Possibility Research president Steve Omohundro at our Bitcoin & the Blockchain Radar Summit to talk about an interesting intersection: artificial intelligence (AI) and blockchain/cryptocurrency technologies. This Radar Podcast episode features our discussion about the role cryptocurrency and blockchain technologies will play in the future of AI, Omohundro’s Self Aware Systems project that aims to ensure intelligent technologies are beneficial for humanity, and his work on the Pebble cryptocurrency.

Synthesizing AI and crypto-technologies

Bitcoin piqued Omohundro’s interest from the very start, but his excitement built as he started realizing the disruptive potential of the technology beyond currency — especially the potential for smart contracts. He began seeing ways the technology will intersect with artificial intelligence, the area of focus for much of his work:

I’m very excited about what’s happening with the cryptocurrencies, particularly Ethereum. I would say Ethereum is the most advanced of the smart contracting ideas, and there’s just a flurry of insights, and people are coming up every week with, ‘Oh we could use it to do this.’ We could have totally autonomous corporations running on the blockchain that copy what Uber does, but much more cheaply. It’s like, ‘Whoa what would that do?’

I think we’re in a period of exploration and excitement in that field, and it’s going to merge with the AI systems because programs running on the blockchain have to connect to the real world. You need to have sensors and actuators that are intelligent, have knowledge about the world, in order to integrate them with the smart contracts on the blockchain. I see a synthesis of AI and cryptocurrencies and crypto-technologies and smart contracts. I see them all coming together in the next couple of years.

Beyond bitcoin and the blockchain to booming business

Widespread blockchain adoption requires understanding between developers and domain experts.

Chain_of_fate_Hiroyuki_Takeda_Flickr

Editor’s note: this post is part of our investigation into the future of money. The full video compilation from our first event, Bitcoin & the Blockchain, is now available.

The vision for bitcoin and the blockchain is unabashedly optimistic, though already it is being realized. More and more technologists, venture capitalists, financial institutions, and even regulators are seeing its long-term potential to transform industries, from financial services to data management to the Internet of Things. In the medium term, there remain hurdles to overcome before blockchain technology can offer sufficiently compelling solutions for the complex financial and technological world we live in, but there is progress to date — and it’s promising.

Blockchain-based remittance vehicles offered by Coins.ph, BitPagos, and BitPesa, though early stage, aim to take a chunk of the $450 billion remittance industry by offering speedier, more efficient, and cheaper alternatives to traditional solutions. BitPay offers bitcoin/fiat payment processing for merchants as well as bank integration. Increasingly, private investors are diversifying their portfolios by purchasing bitcoin alongside traditional assets. Most recently, Coinbase even received funding from a group of blue-chip investors, including the New York Stock Exchange, and launched its own exchange, signaling both greater acceptance by the financial services industry as well as confidence in its future value. Ripple Labs has taken a very different approach with its protocol, permitting the decentralized transmission of practically any currency type — cryptographic or fiat — like an SMTP for money, and circumventing traditional payment networks. And to this end, it’s already inked agreements with Cross River Bank (New Jersey), CBW Bank (Kansas), and Fidor Bank (Germany), with more on the horizon. Read more…
