- Andrew Ng (Wired) — I think self-driving cars are a little further out than most people think. There’s a debate about which one of two universes we’re in. In the first universe it’s an incremental path to self-driving cars, meaning you have cruise control, adaptive cruise control, then self-driving cars only on the highways, and you keep adding stuff until 20 years from now you have a self-driving car. In universe two you have one organization, maybe Carnegie Mellon or Google, that invents a self-driving car and bam! You have self-driving cars. It wasn’t available Tuesday but it’s on sale on Wednesday. I’m in universe one. I think there’s a lot of confusion about how easy it is to do self-driving cars. There’s a big difference between being able to drive a thousand miles, versus being able to drive anywhere. And it turns out that machine-learning technology is good at pushing performance from 90 to 99 percent accuracy. But it’s challenging to get to four nines (99.99 percent). I’ll give you this: we’re firmly on our way to being safer than a drunk driver.
- Google Cloud BigTable — Google’s BigTable, with Apache HBase API, single-digit millisecond latency, and “fully managed”. G are hell-bent on catching up with Amazon and Microsoft at this cloud serving thing.
- Call Me Maybe: Aerospike — We’re setting a timeout of 500ms here, and operations still time out every time a partition between nodes occurs. In these tests we aren’t interfering with client-server traffic at all. Aerospike may claim “100% uptime”, but this is only meaningful with respect to particular latency bounds. Given Aerospike claims millisecond-scale latencies, you may want to reconsider whether you consider this “uptime”.

The O'Reilly Solid Podcast: Amanda Peyton of Etsy on the rise of craft.
Our new episode of the Solid Podcast brings us to Etsy, where David and I spoke with Amanda Peyton, a serial entrepreneur and product manager at Etsy, about the company’s role as a macro-community of micro-communities.
The connection between Etsy and Solid might not be obvious at first. Etsy’s specialty is the ultra-analog: handmade crafts that represent a return to an earlier era of artisan design and manufacturing.
But Etsy is emblematic of how Web platforms have transformed the relationship between product creators and product consumers. It offers rapid feedback from the market, quick discovery of new trends, and access to a large and diverse enough customer base that even extraordinarily niche products can be viable.
The result is a community of distributed manufacturers that’s responsive and efficient. For goods that can be made without a large, well-capitalized factory (even some electronics now fall into this category), Etsy may be the future of manufacturing. Read more…
Scale-out applications need scaled-in virtualization.
Data center operating systems are emerging as a first-class category of distributed system software. Hadoop, for example, is evolving from a MapReduce framework into YARN, a generic platform for scale-out applications.
To enable a rich ecosystem of diverse applications to coexist on these platforms, providing adequate isolation is crucial. The isolation mechanism must enforce resource limits, decouple software dependencies among applications and the host, provide security and privacy, confine failures, etc. Containers offer a simple and elegant solution to the problem. However, a question that comes up frequently is: Why not virtual machines (VMs)? After all, these systems face a number of the same challenges that have been solved by virtualization for traditional enterprise applications.
All problems in computer science can be solved by another level of indirection, except of course for the problem of too many indirections” — David Wheeler
From linear models to neural networks: an interview with Reza Zadeh.
Get notified when our free report, “Future of Machine Intelligence: Perspectives from Leading Practitioners,” is available for download. The following interview is one of many that will be included in the report.
As part of our ongoing series of interviews surveying the frontiers of machine intelligence, I recently interviewed Reza Zadeh. Reza is a Consulting Professor in the Institute for Computational and Mathematical Engineering at Stanford University and a Technical Advisor to Databricks. His work focuses on Machine Learning Theory and Applications, Distributed Computing, and Discrete Applied Mathematics.
- Neural networks have made a comeback and are playing a growing role in new approaches to machine learning.
- The greatest successes are being achieved via a supervised approach leveraging established algorithms.
- Spark is an especially well-suited environment for distributed machine learning.
David Beyer: Tell us a bit about your work at Stanford
Reza Zadeh: At Stanford, I designed and teach distributed algorithms and optimization (CME 323) as well as a course called discrete mathematics and algorithms (CME 305). In the discrete mathematics course, I teach algorithms from a completely theoretical perspective, meaning that it is not tied to any programming language or framework, and we fill up whiteboards with many theorems and their proofs.

The O'Reilly Radar Podcast: Steve Omohundro on AI, cryptocurrencies, and ensuring a safe future for humanity.
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.
Designers need not start from scratch as they wrestle with orchestrating experiences that span digital and physical.

Two of our richest senses, smell and taste, are not often associated with design. However, the creation of objects that support these senses is an ancient practice, embodied best by the tea set, where rituals of assembly and service lead to hints of the aroma. Holding the tea cup warms your hand without burning it, and the slow sipping of the tea forms a communal bond with other participants. Outside of classic and common serving items, designers today are increasingly finding new ways to collaborate with chefs and food companies to design with smell and taste in mind, forging a new frontier for sensorial design.
Martin Kastner is the founder and principal of Crucial Detail, a studio in Chicago that specializes in custom pieces to support unique culinary experiences. Martin is best known for his work designing serviceware concepts for Alinea, the 3-star Michelin restaurant founded by chef Grant Achatz. That collaboration has extended to other restaurants owned by Achatz, including The Aviary, a cocktail bar that prides itself on serving drinks with the same level of attention as a fine dinner.At The Aviary, one of the most popular creations by Crucial Detail is the Porthole Infuser, a round vessel that presents the ingredients of a patron’s cocktail between two flat panes of glass, emphasizing the transformative action of the steeping process and building anticipation for the cocktail’s taste. The Porthole Infuser takes a part of the preparation process that is normally hidden and brings it directly to the person’s table, providing time for the drinker to contemplate the ingredients on display, creating a mental checklist for their tongue to seek out when they take their first sip.
The popularity of the Porthole Infuser at the Aviary led Kastner to create a Kickstarter campaign to fund the additional design and manufacturing required to release it as a commercial product. Support for the project was dramatic, achieving 25 times more funding than originally asked. This backing set the course for a redesign that allowed the infuser to be manufactured at scale and sold for $100, down from the several hundred dollars that each custom constructed version for The Aviary cost.
The Porthole Infuser is marketed as more than a cocktail tool, working equally well to support the smell and taste of oils, teas, or any other infusion recipe. It’s an example of how designers can enhance the dining experience, not by crafting the smell or taste of the food itself, but working in collaboration with a chef to heighten our awareness of those senses.
