Incoming Gantz-Led Government to Invest in Israel’s Infrastructure

Israel’s incoming prime minister Benny Gantz unveiled an emergency government, to take power following an upcoming confidence vote in the Knesset. The last two MKs required to give Gantz a 61-59 majority, two members of Gantz’s own Blue and White Party who were previously resolute not to go into coalition supported by the mostly Arab […]

Finding home in the time of coronavirus

Disclaimer: I’m going to say this once. Obviously, I am not happy about the coronavirus’s threat to public health or the economic toll it’s taking. I do not think the existence of this pandemic is good. Just so happens that social distancing and remote work suits me. I am truly an introvert, and this whole […]

Have it all: take your spouse’s name socially

When you get married, you are creating a family. One way to reinforce that is to have the same name. But whose name do you pick? Do you hyphenate? Do you not hyphenate, and never have a simple time filling out a form again (like my friends the Rabideau Childerses)? Do you make a new […]

Mixing and Matching

In public transportation as in many other aspects, an important fact of improvement is being able to mix-and-match things that work from different sources. It’s rare to have a situation in which exact importation of one way of doing things is the best in every circumstance (and the Covid-19 crisis appears to be one of […]

Europe and Asia are not Liberal or Conservative America

One frustrating thing coming from telling Americans to be more like democratic Asia, or even more like Europe, is that it is a) a political claim, that b) doesn’t neatly map onto partisanship or even intra-partisan political factions. Demographically, it appeals to more educated people, and to people who identify with more educated political movements […]

New York is Shrinking

The US Census Bureau has just released 2019 population estimates by county. Metro New York, after slowly rising for decades more than making up the 1970s losses, went down by 60,000 people, or 0.3% of the population. The city is down 53,000 people. Why? The city chooses stagnation and ignorance. In the 1970s, the city […]

This is not World War Two

Entrenched hierarchies do not like outside criticism, especially when it’s right. They fight off knowledge that they don’t have or can’t control. In a business setting, the main way out is to found a competing company and drive the one that won’t change out of business. But when it’s not possible, the way out involves […]

Several grumpy opinions about remote work at Tailscale

As a "fully remote work" company, we had to make some choices about the technologies we use to work together and stay in touch. We decided early on - about the time we realized all three cofounders live in different cities - that we were going to go all-in on remote work, at least for engineering, which for now is almost all our work. As several people have pointed out before, fully remote is generally more stable than partly remote. In a partially remote team, the remote workers seem to …

How (some) good corporate engineering blogs are written

I've been comparing notes with people who run corporate engineering blogs and one thing that I think is curious is that it's pretty common for my personal blog to get more traffic than the entire corp eng blog for a company with a nine to ten figure valuation and it's not uncommon for my blog to get an order of magnitude more traffic. I think this is odd because tech companies in that class often have hundreds to thousands of employees. They're overwhelmingly likely to be better …

Boston should begin aggressive coronavirus mitigation

TL;DR: The limited public evidence suggests Boston has likely failed at containing the coronavirus. State officials should start communicating more transparently about the current status of the outbreak, and the city should cancel large events, in particular the St. Patrick’s Day parade. If you agree, call your elected officials to ask for better communication and aggressive mitigation measures. (Epistemic status: I’m not an epidemiologist, I just like extrapolating exponential growth.)

The growth of command line options, 1979-Present

My hobby: opening up McIlroy’s UNIX philosophy on one monitor while reading manpages on the other. The first of McIlroy's dicta is often paraphrased as "do one thing and do it well", which is shortened from "Make each program do one thing well. To do a new job, build afresh rather than complicate old programs by adding new 'features.'" McIlroy's example of this dictum is: Surprising to outsiders is the fact that UNIX compilers produce no listings: printing can be do…

Being smart

Being smart is rad. As a tool, it mostly lives up to the hype. But it can never define the real you. Or fill the hole in your heart... The more I've given to being smart the emptier it feels. I thought being smart would allow me to be secure in myself, finally sure that I wasn't making a mistake by loving myself.

You don't need to work on hard problems

For some reason, a lot of smart college students end up with the idea that “solving hard technical problems” is the best thing they can do with their life. Why does this happen? Probably because that’s the only thing they’ve been rewarded for over the past 15 years.

Suspicious discontinuities

If you read any personal finance forums late last year, there's a decent chance you ran across a question from someone who was desperately trying to lose money before the end of the year. There are a number of ways someone could do this; one commonly suggested scheme was to buy put options that were expected to expire worthless, allowing the buyer to (probably) take a loss. One reason people were looking for ways to lose money was that, in the U.S., there's a hard income cutoff for a hea…

Watering the plant

My old approach to depression and anxiety was to take a wilted plant (me) and try to engineer exactly how to force it to stand up straight again. “Reinforce the stem!” “Correct droop 30 degrees!” “Leaves, uncrinkle!” And then I went about implementing those changes, essentially by rigging up a traction apparatus to hold the […]

95%-ile isn't that good

Reaching 95%-ile isn't very impressive because it's not that hard to do. I think this is one of my most ridiculable ideas. It doesn't help that, when stated nakedly, that sounds elitist. But I think it's just the opposite: most people can become (relatively) good at most things. Note that when I say 95%-ile, I mean 95%-ile among people who participate, not all people (for many activities, just doing it at all makes you 99%-ile or above across all people). I'm also not referri…

It's ok to feed stray cats

Before we had kids, Jeff and I fostered a couple of cats. One had feline AIDS and was very skinny. Despite our frugal grocery budget of the time, I put olive oil on her food, determined to get her healthier. I knew that stray cats were not a top global priority, and that this wasn’t even the best way of helping stray cats, but it was what I wanted to do.. . . . .The bike path near where I live has a lot of broken glass on the ground nearby.

Hedonic asymmetries

Creating really good outcomes for humanity seems hard. We get bored. If we don’t get bored, we still don’t like the idea of joy without variety.

Moral public goods

Algorithms interviews: theory vs. practice

When I ask people at trendy big tech companies why algorithms quizzes are mandatory, the most common answer I get is something like "we have so much scale, we can't afford to have someone accidentally write an O(n^2) algorithm and bring the site down"1. One thing I find funny about this is, even though a decent fraction of the value I've provided for companies has been solving phone-screen level algorithms problems on the job, I can't pass algorithms interviews!

The unreasonable effectiveness of one-on-ones

When I started dating my partner, I quickly noticed that grad school was making her very sad. This was shortly after I’d started leading an engineering team at Wave, and so the “obvious” hypothesis to me was that the management (okay, “management”) one gets in graduate school is totally ineffective. Most graduate students, including Eve, start school right after college, i.e., without much clue about how to effectively do self-directed work.

git-subtrac: all your git submodules in one place

Long ago, I wrote git-subtree to work around some of my annoyances with git submodules. I've learned a lot since then, and the development ecosystem has improved a lot (shell scripts are no longer the best way to manipulate git repos? Whoa!). Thus, I bring you: git-subtrac. It's a bit like git-subtree, except it uses real git submodules.

What do executives do, anyway?

An executive with 8,000 indirect reports and 2000 hours of work in a year can afford to spend, at most, 15 minutes per year per person in their reporting hierarchy... even if they work on nothing else.

Absolute scale corrupts absolutely

The Internet has gotten too big. Growing up, I, like many computery people of my generation, was an idealist.

There's a more common kind of chart, which shows how the languages themselves evolved. I didn't want to show the point of view of language inventors, but rather language users, and see what came out.

You have more than one goal, and that's fine

When people come to an effective altruism event for the first time, the conversation often turns to projects they’re pursuing or charities they donate to.

To be fair, this is a reasonable thing to be apprehensive about, because many youngish people in EA do in fact have this idea that everything in life should be governed by cost-effectiveness. I&…

Then I learned that GIFs can only use 256 colors and we have to do something to map the many colors to the fewer colors. We could just use the closest available color in the new set of colors, but that results in sharp jumps and "color banding" where the colors change. So instead we use (and Image…
