Andreessen Horowitz's Chris Dixon and Balaji Srinivasan discuss the state of the Bitcoin ecosystem now that the Mt. Gox dust has settled. What's next in crypto-currency, and a theory on Bitcoin creator Satoshi (not Dorian) Nakamoto. 

a16z Podcast: The State of the Bitcoin Ecosystem, and a Theory on Satoshi

Suppose you develop a new technology that is valuable to some industry. The old approach was to sell or license your technology to the existing companies in that industry. The new approach is to build a complete, end-to-end product or service that bypasses existing companies. Andreessen Horowitz’s Chris Dixon, Balaji Srinivasan and Benedict Evans discuss the reasons behind, and advantages of, going “full stack.”

a16z Podcast: The Rise of Full Stack Startups

The datacenter has long been -- there's no nice way to put this -- a bit of a snoozer. Expensive boxes running expensive software. No more, says a16z General Partner Peter Levine. Along with Chris Dixon, Levine lays out a vision for the datacenter of the future. Building on the technology established by companies like Facebook and Google, Levine and Dixon describe a software-led transformation of the datacenter, one where the mobile supply chain and fast-moving companies are reimagining everything -- from the underlying architecture to new business models. Be prepared to get in the weeds, hear Levine talk about the next opportunity, “hosted instances,” Dixon describe the “the dream within the dream,” and discover why the datacenter is about to get exciting.

a16z Podcast: Datacenter of the Future

Open source software has permeated practically every nook of the software world. The biggest companies and largest-scale systems all lean heavily on open source code. Yet, with the exception of Red Hat, no one has built a great business on top of open source software. That’s because what companies should be selling isn’t necessarily the software, or even support, says a16z’s Peter Levine, but a service that leverages open source. One example of such a service is DigitalOcean, which has built a cloud environment tailored to the needs of developers. DigitalOcean CEO  and cofcounder Ben Uretsky joins Levine from his New York City HQ for a discussion about open source-as-a-service, how companies of all sizes should think about leveraging open source, and whether we’ll start to see a slew of specialized clouds geared toward different verticals.

a16z Podcast: An Open Source Business Model That Works

It’s well understood that bitcoin can be used to buy and sell things/services, and the ecosystem of people accepting the cryptocurrency as payment is expanding. But what else can we use the underlying protocol for? How can we expand the same system that enables bitcoin-the-currency to flow and transactions to be recorded? This discussion (from the a16z Academic Roundtable 2014) examines that question, and answers why the currency is just the beginning of the story when it comes to this technology.

a16z Podcast: Beyond Bitcoin -- The Blockchain

With the rise of mobile phones equipped with GPS, we're meeting many more data scientists at start-ups and large companies who specialize in spatio-temporal pattern recognition. Analyzing “moving dots” requires specialized tools and techniques. A few months ago, I sat down with Rajiv Maheswaran founder and CEO of Second Spectrum, a company that applies analytics to sports tracking data. Maheswaran talks about the tools and techniques required to analyze new kinds of sports data.

Apache Spark's Journey From Academia To Industry

O’Reilly’s big data guru Ben Lorica sits down with prominent data scientist DJ Patil to talk about his new ebook (written with Hilary Mason) and other topics in data science and big data.

A Brief Look At Data Science's Past And Future

In this episode of the Data Show, I spoke with Roger Chen, co-founder and CEO of Computable Labs, a startup focused on building tools for the creation of data networks and data exchanges. Chen has also served as co-chair of O'Reilly's Artificial Intelligence Conference since its inception in 2016. This conversation took place the day after Chen and his collaborators released an interesting new white paper, "Fair value and decentralized governance of data." Current-generation AI and machine learning technologies rely on large amounts of data, and to the extent they can use their large user bases to create “data silos,” large companies in large countries (like the U.S. and China) enjoy a competitive advantage. With that said, we are awash in articles about the dangers posed by these data silos. Privacy and security, disinformation, bias, and a lack of transparency and control are just some of the issues that have plagued the perceived owners of “data monopolies.”

Acquiring and Sharing High-Quality Data

In this episode of the Data Show, I speak with Cassie Kozyrkov, technical director and chief decision scientist at Google Cloud. She describes "decision intelligence" as an interdisciplinary field concerned with all aspects of decision-making, and which combines data science with the behavioral sciences. Most recently she has been focused on developing best practices that can help practitioners make safe, effective use of AI and data. Kozyrkov uses her platform to help data scientists develop skills that will enable them to connect data and AI with their organizations' core businesses.

We had a great conversation spanning many topics, including:

How data science can be more useful

The importance of the human side of data

The leadership talent shortage in data science

Is data science a bubble?

Make Data Science More Useful

In this episode of the Data Show, I speak with Alex Ratner, project lead for Stanford’s Snorkel open source project; Ratner also recently garnered a faculty position at the University of Washington and is currently working on a company supporting and extending the Snorkel project. Snorkel is a framework for building and managing training data. Based on our survey from earlier this year, labeled data remains a key bottleneck for organizations building machine learning applications and services.

Ratner was a guest on the podcast a little over two years ago when Snorkel was a relatively new project. Since then, Snorkel has added more features, expanded into computer vision use cases, and now boasts many users, including Google, Intel, IBM, and other organizations. Along with his thesis advisor professor Chris Ré of Stanford, Ratner and his collaborators have long championed the importance of building tools aimed squarely at helping teams build and manage training data. With today’s release of Snorkel version 0.9, we are a step closer to having a framework that enables the programmatic creation of training data sets.

Labeling, Transforming, and Structuring Training Data Sets for Machine Learning

In this episode of the Data Show, I speak with Kesha Williams, technical instructor at A Cloud Guru, a training company focused on cloud computing. As a full stack web developer, Williams became intrigued by machine learning and started teaching herself the ML tools on Amazon Web Services. Fast forward to today, Williams has built some well-regarded Alexa skills, mastered ML services on AWS, and has now firmly added machine learning to her developer toolkit.

Becoming a Machine Learning Practitioner

In this episode of the Data Show, I speak with Michael Mahoney, a member of RISELab, the International Computer Science Institute, and the Department of Statistics at UC Berkeley. A physicist by training, Mahoney has been at the forefront of many important problems in large-scale data analysis. On the theoretical side, his works spans algorithmic and statistical methods for matrices, graphs, regression, optimization, and related problems. On the applications side, he has contributed to systems used for internet and social media analysis, social network analysis, as well as for a host of applications in the physical and life sciences. Most recently, he has been working on deep neural networks, specifically developing theoretical methods and practical diagnostic tools that should be helpful to practitioners who use deep learning.

Understanding Deep Neural Networks

O'Reilly Media spreads the knowledge of innovators. At O’Reilly, a big part of our business is paying attention to what’s new and interesting in the world of technology. We have a pretty good record at having anticipated some of the big technology developments in recent history. For instance, we launched the first commercial Web site, GNN, in 1993; we organized the meeting at which the term “open source” was first adopted; we were early investors in Blogger, which helped launch the blogging revolution; and more recently, our Web 2.0 conference launched a world-wide meme. We call this predictive sense the “O’Reilly Radar.” And while we’re certainly not always right, we are, at least, good at making interesting guesses.

Our methodology is simple: we draw from the wisdom of the alpha geeks in our midst, paying attention to what’s interesting to them, amplifying these weak signals, and seeing where they fit into the innovation ecology. Add to that the original research conducted by our Research team, and you start to get a good picture of what the technology world is thinking about.
