Many months ago, when my brother Max was visiting, Rodolfo and Ciara told us they had gotten a reservation at a site in Big Sur in the spring, and invited us to go camping with them. We were excited to join in. More...

This year’s PyCon took me to Cleveland, OH. Unlike last year’s event in Portland, I was not too excited about the location at first, but I was pleasantly surprised. Continue reading...

I just returned from PyCon, and just like last year it was an inspiring and motivating event. The sheer size of the conference, with its three thousand plus attendees, paired with the ever expanding surface area of all the fields where Python is used means that you’re constantly overwhelmed. Continue reading...

When Max and Einat got married, we decided that instead of giving them a physical thing as a gift, we’d give them an experience that they could enjoy with us. This trip to NYC was it. Continue reading...

• On Radical Markets
  Vitalik Buterin
  

  Coordination problems are fascinating, and this review of Posner and Weyl’s new book gives a taste of their ideas on political economy, with a nice dose of crypto. From immigration, to private property, to the gig economy, the authors seem to have controversial but well founded solutions on how to tackle some of the hardest coordination problems facing society today. Game theory and technology are a great pairing, and one that I don’t think has been explored enough. I can’t wait for this EconTalk episode to come out.

• The Disturbing High Modernism of Silicon Valley
  Cal Newport
  

  Having read Seeing Like a State earlier this year, this article resonated a lot with me. It takes James C. Scott’s message of being wary of authoratitave states bearing technology and good intentions, and applies it to Silicon Valley companies’ good intentions. Some technology companies are governments in their own way, and many of these web services are larger and more powerful than many nation states, allowing them to deploy large projects that affect the lives of millions of people. Unlike sovereign states, which in theory have aligned incentives with their citizens, companies have a series of other constituents with their own interests beyond that of their users. Our lives are starting to be permeated by these services, and, much like nation states, their grip is starting to become inevitable as more and more aspects of our lives are mediated by them.

• Time And Money
  Fred Wilson - AVC
  

  Every business decision is at its core an exchange of time for money and vice versa. This is not just the case of a founder picking a VC, or investors picking startups, but also of employees deciding where to work, and average Joe thinking of where to put their savings.

• Don't Blame Airbnb for Rising Rents
  Noah Smith - Bloomberg View
  

  Gotta love when economic analysis beats bad arguments.

• The Scientific Paper Is Obsolete
  James Somers - The Atlantic
  

  There were a bunch of things I love reading about here. There’s history, there’s complexity science (that’s how I got into CS in the first place), there’s python, there’s UX, and more. If you’re interested in the future of education and the spreading of scientific knowledge this is a must read.

• Facts vs hand-waving in economics
  Chris Dillow - Stumbling and Mumbling
  

  Most traditional economic models are based on bad assumptions: full information, rational agents, etc. Dillow uses the Modigliani-Miller theorem as an example of how this quickly breaks down, and uses it to argue for better undergad education. I mostly agree that there should be a higher emphasis on empiricism.

• The inefficiency of large, infrequent transactions
  Eugene Wei - Remains of the Day
  

  And speaking of perfect information and economic assumptions that make no sense, here’s one that’s ususally ignored altogether at the undergraduate level: symmetric information. This post discusses the problems of infrequent transactions (think a company going public, or a person buying a house) and how one side of this market has a clear advantage over the other.

• Conceptual Compression
  David Heinemeier Hansson - Signal V. Noise
  

  This is a wonderful post about how computer science concepts are abstracted over again and again, making it much easier to build things without knowing the details of what happens under the hood. It made me think of Alfred North Whitehead’s quip: “Civilization advances by extending the number of important operations which we can perform without thinking about them.” It also reminded me of an essay about constraints in programming and how over time we’ve decreased the surface of what a programmers can do, enabling them to do what they actually want to do more easily.

• Like the Ancients, We Have Gods. They’ll Get Greater.
  Robin Hanson - Overcoming Bias
  

  Everyone has been talking about Hanson for other reasons recently. Here he makes an interesting argument about modern celebrities and human nature.

• Trade Wars, Stranded Assets, and the Stock Market (Wonkish)
  Paul Krugman - The New York Times
  

  If you believe in specialization, you should believe Krugman’s argument on trade wars. He basically says there’s two reasons for the stock market’s current drop re the potential trade war: 1) Efficiency loss imposed by artificial costs on international trade, which undo specialization (tariffs). 2) Stranded assets, which are worth more on paper than on the market. I’d say there’s a third thing in play here: behavioral overshooting. In any case, the stranded asset thing is interesting. It isn’t just the soon-to-be unproductive factories in China that lost value, but also their counterparts in the US, like real estate owned by foreigners.

• The Many Traditions of Non-Governmental Money (Part I)
  Nick Szabo - Unenumerated
  

  Sadly, Szabo has not yet released the second part of this series yet. He argues that we’ve forgotten that money used to exist outside of the State’s purview, and it is implied in his argument that cryptocurrencies are just a reversion to older models of money without state intervention.

• The Thing I Love Most About Uber
  Bill Gurley - Above the Crowd
  

  Obviously Gurley is biased about this company, but he makes some really great points about the gig economy, and Uber’s role in kickstarting it. If there’s a single thing that we should thank Kalanick and the company he’s built for, it’s the availabilty of flexible work options.

• The Suicide of the West (Podcast)
  Russ Roberts and Jonah Goldberg - EconTalk
  

  EconTalk has been killing it lately with their interviews. I usually don’t agree with most conservative arguments, but Goldberg makes some really interesting points in this episode. Especially interesting was his point about celebrity (related to Hanson’s from above) and how tribal thinking has overtaken the republican party.

• The Tyranny of Metrics (Podcast)
  Russ Roberts and Jerry Muller - EconTalk
  

  An hour long conversation of what essentially is Goodhart’s law. Clearly the focus is on policy and social cooperation, but a lot of this conversation can be applied to software engineering and entrepreneurship.

• The High Price of Cancer Drugs (Podcast)
  Russ Roberts and Vincent Rajkumar - EconTalk
  

  A great conversation on the economic tradeoffs of healthcare. I recently discussed this with a good friend who’s dad is going through sever medical issues and is in need of a transplant. It is easy to discuss these things in the abstract, but when you put a face to the problem then discussing whether society should cover the cost of medication that could extend someone’s life for another year or two gets way harder. It’s a tough conversation, but one worth listening to.

• Border Trilogy Part 1: Hole in the Fence (Podcast)
  Radiolab
  

  This series on borders is full of maddening stories of how people treat each other at borders. Parts 2 and 3 are also totally worth listening to.

• The Rational Madness Of The Used Car Salesman (Podcast)
  Planet Money
  

  I have never understood the American model of car sales.

• Principles and Algorithms for Work and Life (Podcast)
  a16z Podcast
  

  This interview with Ray Dalio was great. His management philosophies are very controversial, but his success running Bridgewater speaks for itself. Describing the reasoning behind his book, Dalio discusses how he tries to boil everything down to pattern matching. Since most things have some similar precedent in the past, you can look at previous instances and act according to what history tells you will be the successful decision. Essentially, it’s real life Duck Typing. If you define ahead of time what your principles are, and how you’d behave in a certain situation based on your knowledge of previous experiences, then nothing is surprising. Importantly, you have to be a student of history for this strategy to work.

• Feedback Loops — Company Culture, Change, and DevOps (Podcast)
  a16z Podcast
  

  This conversation tries to showcase philosophies and practices from the software engineering world to a less technical audience, but does end up going in the weeds. The main idea behind dev-ops is one I subscribe to: empowering engineers to not only be in charge of designing and building a new feature, but also of deploying it, measuring its reliability, and owning its delivery throughout its life. By virtue of having one group of people responsible for the whole life cycle, there is an alignment of incentives that leads to more reliable, easier to deploy software.

• Improv’ing Leadership (Podcast)
  a16z Podcast
  

  Dick Costolo is an unusual guy for Silicon Valley. This interview gives a window into his background in theatre and improv comedy, and how those experiences changed his management style for the better. About halfway through, he made a great remark: “As a leader, it’s not your job to prevent mistakes from happening, it’s your job to correct them when they happen.” I could not agree more. When you’re trying to prevent errors, everything slows down, and innovation stops. It’s the opposite of what you want.

• Random Acts of History (Podcast)
  This American Life
  

  Teaching requires empathy in order to figure out how to transfer knowledge that has already been synthesized in their teacher’s head to the student, who has a very different set of anchor knowledge than whatever the teacher already does. To put themselves in the shoes of the student, and make a new idea accessible to them in known terms is what makes teaching hard. Good museums, movies, and books, are built by people who recognize that fact. The first act, where a group of black kids are innocently brought to the movies to watch Schindler’s list was fascinating, precisely because the protagonist teacher had not considered that those kids would have no anchor to understand the movie.

• Python Environment
  Randall Munroe - xkcd
  

  Ah, the joy of Python
