So You Want to Launch a Newsletter: Tips From Substack Writers

One of the most active and fastest growing open source big data cluster computing projects is Apache Spark, which was originally developed at U.C. Berkeley's AMPLab and is now used by internet giants and other companies around the world. Including, as announced most recently, IBM. In this Q&A with Spark inventor Matei Zaharia -- also the CTO and co-founder of Databricks (and a professor at MIT) -- on the heels of the recent Spark Summit, we cover the difference between Hadoop MapReduce and Spark; what are the ingredients of a successful open source project; and the story of how Spark almost helped a friend win a million dollars.

Investing to make a return both financial AND societal isn't new, but the opportunities to reach and build businesses in communities that have been underserved by tech are larger than ever. One example is the business opportunity presented by hairstylist platform Mayvenn, which a16z recently backed. In this segment of the a16z Podcast, Kesha Cash (founder and general partner of the Impact America Fund, also an investor in Mayvenn) discusses how she puts her fund’s money to work in markets that target underserved Americans. Cash is joined by a16z’s Tawny Holguin (who leads our seed and early scouting efforts) to breakdown the intricacies -- and opportunities -- of so-called “impact investing.” Do core business principles change at all? But then how does impact get measured? And what happens when you connect more communities to tech?

"This time is different." But it's always different! So what's going on now in the public markets? Why does this even matter? For one thing, tech markets have grown significantly. And one big reason is internet and mobile. It's like a multiplier for the market size and opportunity. In this episode of the a16z Podcast, Andreessen Horowitz managing partner Scott Kupor, mobile analyst Benedict Evans, and corp dev research partner Morgan Bender break down a slide deck we recently shared, including answers to what all these so-called “unicorns” are, how it affects venture capital and the funding landscape, and how we define a "quasi-IPO."

Pick your metaphor: Smartphones are "remote controls" for the physical world, or perhaps, as Steve Cheney argues, they're "cursors for the physical world". Either way, it's clear that the age of mobile is here, GPS is not enough, and with sensors all around us -- both outdoors and in indoor locations -- it's finally time for truly context-aware computing. But what will that take, both content- and design-wise -- is it all just about eliminating friction? And how are players like Apple and Google positioning themselves for this micro-mapped world? a16z's Benedict Evans and Estimote's Steve Cheney talk about these questions and more in this episode of the a16z Podcast...

Every meeting a busy founder takes is time away from building the company. So it’s understandable why engaging corporate development groups is believed to be a waste of time, unless you’re selling your company. But... there ARE good reasons to engage corporate development. You just have to know when, and how. And what to avoid! On this episode of the a16z Podcast, operating partner Jamie McGurk, and Tyson Clark and James Loftus (veterans of corporate development from companies like Google, Oracle, and Yahoo) share advice for founders talking to corporate development.

Apple’s annual developer conference is cranking away in San Francisco, and a16z’s Benedict Evans examines the latest from the world’s most valuable company in this segment of the pod. Software is the star of WWDC and Apple highlighted updates to iOS and OS X, but the big news was in part Apple News -- a curation and aggregation app for periodicals. Newsstand, Apple’s earlier attempt to tackle news outlets on your Apple device didn’t catch on, but Evans gives Apple News a better chance. And Apple Music? “It was a bit wooly, frankly,” Evans says. Translation: it didn’t amaze. Evans explains why.

Is the Apple Watch breaking new technological ground, or just another accessory for your iPhone? a16z’s Benedict Evans and Board Partner Steven Sinofsky describe their experience with the Apple Watch one month after strapping the elegant piece of electronics to their wrists. So how is it? It’s not the one thing you will own that will fill this void in your life like the iPhone did, Evans says. And working out what is useful and pleasurable about the Apple Watch takes time, he says. Even so, Evans finds himself getting there. For example, being prodded by the watch’s map app to turn left or right while walking to your destination “is like a super-power,” he says. Sinofsky too is finding his Apple Watch more alluring than he had anticipated. What will really make the Apple Watch a piece of kit that people won’t want to part with is the evolution of the apps -- building novel things just for the watch that don’t mimic what we do on smartphones or any other existing piece of technology. “We’re in the phase right now (with the Apple Watch) where people are trying to figure out how to do the old things in a new way,” Sinofsky says. “And really, you need to do new things in a new way.”

Distributed computing frameworks like Hadoop and Spark have enabled processing of "big data" sets -- but that's not enough for modeling surprise/rare "black swan" or complex events. Just think of scenarios in disaster planning (earthquakes, terrorist attacks, financial system collapse); biology (including disease); urban planning (cities, transportation, energy power grids); military defense ... and other complex systems where unknown behaviors and properties can emerge. They can't be modeled based on (by definition impossible) limited data. And parallelization for this is hard. But what if companies and governments could answer these seemingly impossible questions -- through simulations? Especially ones where we can directly merge in knowledge and cues from the real world (sensors, sensors everywhere)? CEO of Improbable Herman Narula and Stanford University professor-in-residence at a16z Vijay Pande discuss this and more with Chris Dixon in this episode of the a16z Podcast.
