The bipartisan infrastructure framework (BIF) just passed the Senate by a large margin, with money for both roads and public transportation. Unlike the 2009 Obama stimulus, the BIF has plenty of money for high-speed rail – not just $8 billion as in the 2009 bill, but a total of $66 billion to be spent on […] This is the fifth and final part (I, II, III, IV) of our series asking the question ‘Who were the Romans?’ How did they understand themselves as a people and the idea of ‘Roman’ as an identity?

Welcome to this week's edition of "building a startup in 2020," in which all
your meetings are suddenly remote, and you probably weren't prepared for it.
I know I wasn't. We started a "fully remote" company back in 2019, but that
was supposed to mean we still got together in person every month or two to
do strategic planning, share meals, and resolve any accumulated
conflicts. Well, not this year. Instead, we had to learn to have better

I love Nora. She is a really fun sister. I give her a hug and a kiss
each night. Nora is pretty much always nearby so I can go and cuddle
her. Unless she's nursing. Or sleeping. Or having her diaper
changed. Which is a lot of the time. But, overall, Nora is a really
really fun sister. She's also very silly, and she makes silly faces.
I hope everyone will forgive me taking this week to break from our normal diet of history-and-pop-culture (though we are discussing a key historical concept here – it is me after all), but it is the July 4th weekend and I have been meaning to treat this topic for a while now. I must further … Continue reading Collections: My Country Isn’t a Nation →
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 … 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.

Writing is a profoundly dangerous technology:
Access to writing was initially, and still remains, uneven. What's worse, the rich are more likely to be literate, so it not only creates inequalities but exacerbates existing ones.
Written language embodies the biases and prejudices of the people responsible for writing. Writing makes those prejudices more permanent and influentia… Previously: gift ideas for young children (0-2) I thought I’d list some toys our kids have especially liked.

Today I made valentines. I made fruit valentines. There were orange
fruit valentines, and grape fruit valentines, watermelon fruit
valentines, and pineapple too. I made them for my classmates and
teacher. They had a little jokes or puns on the back. The jokes or
puns were on a sticker that we could stick on the back. I stuck on
googly eyes, and I drew a mouth. I added hearts and a sticker.
That's how I made the valentines. Here is a picture so you can see

"Systems design" is a branch of study that tries to find universal
architectural patterns that are valid across disciplines.
You might think that's not a possibility. Back in university,
students used to tease the Systems Design Engineers, calling it "boxes and
arrows" engineering. Not real engineering, you see, since it didn't touch
anything tangible, like buildings, motors, hydrochloric acid, or, uh,
electrons.
I don't think the Systems Design people took this critici…
In the classic 1986 essay, No Silver Bullet, Fred Brooks argued that there is, in some sense, not that much that can be done to improve programmer productivity. His line of reasoning is that programming tasks contain a core of essential/conceptual1 complexity that's fundamentally not amenable to attack by any potential advances in technology (such as languages or tooling). He then uses an Ahmdahl's law argument, saying that because 1/X of complexity is essential, it's impossible to …

Why it’s worth it to deeply understand the fiddly, boring-seeming details of the computer systems you use every day. A UBI (e.g. paying every adult American $8k/year) would reduce recipient’s need for money and so may reduce their incentive to work. This is frequently offered as an argument against a UBI (or as an argument for alternative policies like the EITC that directly incentivize work). This argument is sometimes presented as economically hard-headed realism. … More It’s not economically inefficient for a UBI to reduce recipient’s employment I spent way too long figuring out the how to make video calls feel natural. Here’s the best advice I came up with. Most people benefit significantly from privately funded public goods (e.g. Wikipedia). If we all contribute to such public goods, then we can all end up better off. But as an individual it’s almost never a good return on investment. I think of supporting such public goods as being a good citizen, but that leaves open … More Distributed public goods provision
I came up with this game. In the game one person thinks of something
and then gives the other person a clue. And the other person writes a
guess down on a blackboard or a piece of paper. Or really anything
you have that's laying around that's available for writing on. The
other person says whether it's right or wrong. And then when they get
it right the other person takes a turn. When they get it wrong the
other person gives them another clue and they guess again. It has to

A few years ago I wrote The World in Which IPv6 was a Good
Design. I'm still
proud of that article, but I thought I should update it a bit.
No, I'm not switching sides. IPv6 is just as far away from universal
adoption, or being a "good design" for our world, as it was three
years ago. But since then I co-founded a company that turned out to be
accidentally based on the principles I outlined in that article. Or
rather, from turning those principles upside-down.
In that article, I exp…
Any time you have a benchmark that gets taken seriously, some people will start gaming the benchmark. Some famous examples in computing are the CPU benchmark specfp and video game benchmarks. With specfp, Sun managed to increase its score on 179.art (a sub-benchmark of specfp) by 12x with a compiler tweak that essentially re-wrote the benchmark kernel, which increased the Sun UltraSPARC’s overall specfp score by 20%. At times, GPU vendors have added specialized benchmark-detecting code to their…
A lot of people seem to think that distributed tracing isn't useful, or at least not without extreme effort that isn't worth it for companies smaller than FB. For example, here are a couple of public conversations that sound like a number of private conversations I've had. Sure, there's value somewhere, but it costs too much to unlock.
I think this overestimates how much work it is to get a lot of value from tracing. At Twitter, Rebecca Isaacs was able to lay out a vision for how…
We spent one day1 building a system that immediately found a mid 7 figure optimization (which ended up shipping). In the first year, we shipped mid 8 figures per year worth of cost savings as a result. The key feature this system introduces is the ability to query metrics data across all hosts and all services and over any period of time (since inception), so we've called it LongTermMetrics (LTM) internally since I like boring, descriptive, names.
This got started when I was looking for a st…
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 … 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. And joyful experiences only seems good if they are real and meaningful (in some sense we can’t easily pin down). And so on. On the flip side, creating really … More Hedonic asymmetries 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. They often have a sense of nervousness around this, a feeling that the harsh light of cost-effectiveness is about to be turned on everything they do. 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&… I’m late to the party, but I've been thinking about the documentary “The Life Equation” about how people use data to decide make life-and-death decisions. The central example is a woman named Crecencia, a mother of seven who lives in rural Guatemala and has cervical cancer. The doctor treating her knows that screening other women for cancer is more cost-effective than treating this woman, and that the community doesn’t have enough money to fully fund both. The filmmaker writes: “Crecencia’s… Here are three places Jeff and I are donating this year.
