Cities are fractal. You can always go a layer deeper and there’s just as much complexity. Following this principle, I sometimes think it might make sense to just stay in San Francisco my whole life and explore the infinite levels of that fractal. It’s cheaper than interstate or international travel anyway, and according to this framework you get the same amount of interestingness no matter how many levels deep you go. The catch is that whe...

A while back Daniel Frank emailed me about the essay I published about Singapore, and he was skeptical of the idea that the international community would act as a deterrent against authoritarianism in Singapore:First, I don’t think this applies to most countries (for example, look at the muted Western protest to changes in countries like Turkey and Poland). Secondly, I specifically think doesn’t apply to Singapore. The two most influential n...

Epistemic status: My personal impressions from wandering the city for a day. Very likely that I'm missing important nuance in lots of places. If you notice a gap, please let me know! I'm so curious to learn more about Singapore. This is more of a diary entry than a worldview. Not sure how to put a confidence interval on that. 🙂 Epistemic effort: I jotted down notes throughout the day in the city and wrote up this post without lots of editing...

California's housing crisis is not a new problem, but for the first time there's a proposal facing the state legislature that could make a dent: Senate Bill 827, known as SB 827. The bill would change zoning around transit to allow for mid-rise housing. To get a sense of its potential, some friends and I created renderings to illustrate what the bill would make possible. Here's one of them: You can find the rest of the renderings plus more...

Effective software developers know how to manage their ignorance. Studying the inner workings of each dependency and every layer of your stack is a luxury you often can't afford, so it's important to know how and when to make leaps of faith. More than any explicit technical knowledge, this intuition is perhaps the biggest thing that differentiates experienced programmers from inexperienced ones. When I first started coding, painful awareness ...

I spent Tuesday, 6 March 2018 in Ho Chi Minh City, formerly known as Saigon. I like the city’s pre-war name better (not a political statement—I just think it’s prettier ☺️), so I’ll use that throughout the post. Most of the signs around town used "Saigon" rather than HCMC, and some of the locals I spoke to called it that too, so I think it’s kosher. As with Beijing, I was also excited for the food, to get a sense of daily life, and of course ...

I spent Monday, 5 March 2018 in Beijing. The urbanist nerd inside of me was thrilled to see China’s capital. I’d read so much about its astounding growth and change in the past few decade—finally a chance to see it firsthand! I was also excited for the food, to get a sense of daily life, and of course to build my mental map of the city. My key takeaway is that Beijing is an epicenter of cultural and technological change, but the experience ...

I love the feeling of building up a mental map of a once-unfamiliar place. Last week I traveled to several cities that I’d never visited before (Beijing, Saigon, Singapore, Jakarta, and Bangalore), so March has been full of this sensation. I joked with friends that I was "training my neural net". I’d read a lot about two of the cities (Beijing, Singapore), knew a bit about one (Saigon), and knew close to nothing about the others (Jakarta, ...

I originally gave this talk at Typescript Conference 2018. You can find the slides here. TypeScript is a godsend for Webpack and Ethereum developers. In the nascent world of smart contracts, developer-friendly tooling is almost non-existent, the only error message is VM Exception: revert, and bugs can cost millions of dollars. Meanwhile, most Webpack config files are incomprehensible, fragile, and cobbled together from a mess of Stack Overflo...

Epistemic status: Highly uncertain, asserted with ~40% confidence. Low enough that I didn’t publish this piece when I originally wrote it in May of 2016. But a recent first trip to Singapore reaffirmed the intuitions in here. Even if the argument is wrong, I think it’s wrong in interesting ways, and I want to start a conversation about it. Plus, since originally drafting this essay I now have the concept of "epistemic status" in my toolset (h/...

A few weeks ago, JUMP Bikes launched a pilot of 250 bikes in SF. Their fleet is dockless and electric, and I’ve been skeptical of the hype around both features, so I was excited to give it a spin. My experience with GoBike, which by comparison both has stations and is human-powered (for now), has been fantastic. I’ve used it nearly every day (sometimes multiple times a day!) since signing up last spring. I evangelize it to anyone who will lis...

I’m proud to be a beginner! But when it comes to the concrete steps of learning something new, I often feel undue shame about my approach. At first, I thought it was a fear of not knowing things or, more likely, a fear of other people seeing of me as a beginner. This doesn’t add up though. I don’t hesitate to ask questions when I’m stuck, and I pride myself on my love of picking up new skills and learning new things. In fact, going from zero ...

I often use a thesaurus while coding, and I mentioned this fact to a non-programmer friend today. He was shocked, and he said that he thought that programming was mathematical, not lexical. But it’s not so easy to separate out—naming is one of the most important parts of programming (and math!), because it’s how you reduce complexity down to something that you can understand, explain, and maneuver. The conversation reminded me of a post I rea...

My favorite aphorism might be "Give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime". It's a useful idea to incorporate into your life philosophy, both for yourself and others. It's nice to offer help to someone with a problem that you can solve, but far better to teach them how to do it.* On the flip side, when there's something you don't know how to do, I encourage you to find someone who will bot...

This essay from Aeon makes the observation that folktales weren't always about fighting for a noble value. Rather they were just about getting what you want, without framing actions in a strong moral light: Stories from an oral tradition never have anything like a modern good guy or bad guy in them, despite their reputation for being moralising. In stories such as Jack and the Beanstalk or Sleeping Beauty, just who is the good guy? Jack is th...

In an email exchange with Brian Lui, he asked me an interesting question about the rate of flaking in San Francisco: I had a brief question too. I've read that the rate of "flaking" in San Francisco is really high, because everyone is so busy and there is so much to do. But then I thought, wouldn't that lead to an extra strong norm against flaking, because your time is too precious to get flaked on by someone? Apparently this doesn't happen an...

Most people seem to think of themselves as "at the edge" of several communities rather than defined by a single identity. It’s easy to think of yourself as special and that other people are more singularly defined, but that’s a bias stemming from the fact that you’re mostly seeing people in the context of just one of the communities they’re a part of. It can be hard to remember: you just don’t have visibility into their other thoughts and othe...

History is too often reduced to stories of good versus evil. We get the impression that we are somehow different from the people who were bad, and we take for granted that we would never make similar choices. We should learn to empathize with those who make terrible choices — not to pardon their choices nor to deny ourselves the right to grieve, but to recognize when we might be heading down a similar path. If we see them as people and unders...

You can write your Webpack config in Typescript, and it’ll save you a huge amount of pain. Webpack’s docs would lead you to believe that using Typescript requires a hacky customized set up, but in fact it’s as simple as installing a single module and changing your extensions from .js to .ts! You can find the rest of the post at the Webpack blog.

I love doing chores. The more time-consuming they are, the better. I jump at opportunities to empty the dishwasher, and grocery shopping is a highlight of my week. I don’t even mind sorting the trash, as long as I have my phone and some earbuds handy. I used to dread housework as much as the next person. But that all changed when John introduced me to podcasts and audiobooks two years ago. Mundane tasks have become opportunities to learn, to r...

In my previous post, I compiled a list of reasons why on-demand audio is great. Evangelism works best when you make it easy to hit the ground running, so here are a few tips and recommendations. Hopefully this will lower the activation energy for getting started. Podcasts You can download my complete list of subscriptions as an opml file or as more readable json.You should be able to load the opml into most podcast apps by going into Settings ...

The way we live is shaped by our infrastructure—the public spaces, building codes, and utilities that serve a city or region. It can act as the foundation for thriving communities, but it can also establish unhealthy patterns when designed poorly.For decades, San Francisco’s waterfront was dominated by the massive Embarcadero Freeway. The Ferry Building was hidden in the shadow of a grungy overpass, and the double decker highway blocked reside...

Notes from reading Walkable City: How Downtown Can Save America, One Step at a Time by Jeff Speck.Core argument: A walkable city is not just a nice, idealistic notion. Rather, it is a simple, practical-minded solution to a host of complex problems that we face as a society, problems that daily undermine our nation’s economic competitiveness, public welfare, and environmental sustainability.The American health care crisis is at its heart an urb...

I am always a little embarrassed when people find out that I had a car in college. I'm a transit geek after all, and I always encourage friends to take public and on-demand transit rather than generate congestion and consume parking spots. Despite all this, I drove multiple times each week last year, because I felt like it was my only real option to get to places I needed to go around the Bay Area. Now, I rarely drive anymore, and I've become ...

Google feeds its employees well. No Googler's desk is further than 150 feet from a "micro kitchen" stocked with goodies, and the campus is dotted with over 20 restaurants and cafes. Everything on the menu is free of charge to Googlers and their guests, and it includes specialities like creme brûlée and fresh handmade sushi. The perks of working at Google extend far beyond the free food and snacks. Google HQ contains a bowling alley, bocce ball...

Technology enables us to see the world in ways that are inaccessible to our natural senses. In opening these new worlds to us, it encourages introspection and discovery, inflates our cosmic egos, and then puts us back in our place. Discovery of perspective Visual technology plays a key role in human cognition and our sense of self. One primitive example is the mirror, which literally enables self reflection. Mirrors are so deeply ingrained in...

I love the feeling of flow, when I settle into my work and make steady, ruthless progress without distraction. Unfortunately, getting myself into this state is difficult. It usually happens when I am wearing my noise-cancelling headphones and I am at just at that point where my work is challenging but manageable and my mind is fully engaged but not overwhelmed. It also helps to have a bit of time pressure or a due date on the horizon. These c...

Richard Dawkins is very clear on his opinion of creationism and its supporters. In an article published by The Guardian, he stated, "Any science teacher who denies that the world is billions ... of years old is teaching children a preposterous, mind-shrinking falsehood." He continues, "Ignorant, closed-minded, false teachers who stand in their way come as close as I can reckon to committing true sacrilege." Student group Atheists, Humanists, ...

The news is saturated with stories and opinions on guns, and the attention on the issue is heightened with this past year’s dramatic shootings in Aurora and Newtown. Understandably, the response to these horrors involves great emotion. However, in our dialogue about violence and gun ownership, we need to set aside our fears and biases and look at where the facts lead us. Here in the Bay Area, the general response to gun ownership is an autom...
