Parents are competing with multi-trillion dollar companies who have invested untold amounts of cash and resources into making their content addictive. When parents try to help their children, it's an uphill battle -- every platform tha

I think there's a pretty simple explanation for this: It's hard to admit when we're not doing well. It's easy to say that the world is getting worse, that you're worried for the future, but to admit that you person

There’s a basic approach to this using markov chains which works surprisingly well. Scott Aaronson once challenged some students to beat his algorithm — only one student could, who claimed he just “used his free will”. Human randomness isn’

Double entry account is, in fact, what gave “transactional” databases their name: They were meant for financial transactions! Nowadays TigerBeetle is a custom built financial database just for double entry accounting. The implementation is

Especially with Apple, I often see people scared that if they open up their ecosystem, then users will lose one of the most consumer friendly tech companies out there. It’s not just “if apple allows alternative browsers then Chrome will win

Wind gusts were reaching 125 MPH in Boulder county, if anyone’s curious. A lot of power was shut off preemptively to prevent downed power lines from starting wildfires. Energy providers gave warning to locals in advance. Shame that NIST’s b

I keep hearing about how the supply and demand cycles are “lagged” and that this price spike happens every 3-5 years for purely economical reasons. I feel like I’m being gaslit — I don’t recall any such price spikes in the past of this magn

I am always astonished by the range of people who claim their college degree was useless, citing rote memorization and bad classes. I had an entirely different experience and so did most people I know. University gave me the opportunity to

I believe you’re referencing Patrick McKenzie’s takes on fraud, which I agree with — but when he (and others) talk about the optimal amount of fraud they’re usually referring to fraud from “losing money from the company to customers”. This

I love conferences and talks and wish I could go to them more — what stops me is the sudden drop in corporate sponsorship of them. It’s been nearly impossible to convince leadership to spend money to train their employees or to socialize wi

In my experience it tends to be the opposite — I am not a quant (QD) but having worked with a few teams there’s a negative selection for technical expertise. QRs who are good at programming are usually pushed into maintaining infrastructure

Obesity is highly correlated with other medical conditions, from cancer to diabetes to heart disease. I wonder if there is a point at which it is cheaper for health insurance companies to offer subsidized or even free GLP-1s to patients tha

God, I’d love to work for something like this. The closest equivalent thing we have today is (in my mind) places like the Apache Foundation or LetsEncrypt, places that run huge chunks of open source software or critical internet structure.

I actually love performative licensing. Notable examples are the "Stallman License" [1] and the "Pinkest Pink: Available to Everyone except Anish Kapoor" [2] [1] https://github.com/benlk/misc-license

Not all decimal numbers have finite binary representations. 0.3, for example, is 0.010011 with a repeating block of 0011. For some business applications, you know you're being given a base 10 decimal of finite (but possibly very larg

I really wish stories like this traveled farther. As the world fraud economies have grown, most people have remained mostly uninformed about how fraudsters and Ponzi schemes operate -- how they sound, what their founders act like, and how t

“In other languages, it would be considered overkill to write a full parser when a simple regex can do the same thing. In Haskell, writing a parser is no big deal. We just do it and move on with our lives.” I see a long code file filled wit

Rust’s “mutable-xor-aliased” model makes it particularly amenable to developing verification tools on top of it [1]. Without this model, verification becomes just as hard — and just as practically intractable — as all the verifiers for exis

I will never stop supporting Lina Khan. Her tenure at the FTC has accomplished more in the past four years than the past four decades.
