Oops, that's what I get for mathing before coffee-- mixed up the formula for \sum (1+r)^n vs. \sum r^n

It may be "free money" as you frame it. But a cash stream that provides n dollars per year forever can be valued in today's dollars, assuming a discount rate of d, at n / (1-d). So…

Tons of comments already in the direction of 'eat less' and 'exercise more'. Of course. One thing I've found extremely helpful is to cook more! WFH is amazing for this. If you can …

When you say tech industry pays more, I'm assuming the effective long-run hourly earnings of poker players is way less glamorous than it looks from an outsider seeing highlights? D…

It's interesting to compare this to the physical-world analog. What if somebody shows up at the US-Canada border, start shooting rockets at Canada, and the US refuses to acknowledg…

See Matt Levine's 10 laws of insider trading. In particular, "5. Don’t do it by planting bombs at a company and shorting its stock." Somebody nicely put a non-paywall link here: ht…

I started looking at the map in the article and realized I had just booked a flight where there was an existing rail line ! So I checked out the Amtrak site, and what's 1h20m by pl…

As an employee at a megacorp, sure, you can see a little bit about how things are going from the inside. That said, you probably spend less time looking at reports than professiona…

As somebody with some ML background but no expertise in crypto, is the following ELI~20 summary correct? We take an ML model trained on unencrypted data, use a 'homomorphic evaluat…

Any good references on the art part, or is it just an intuition you develop over time? In my experience, all the ML education will teach you a ton of theory and basics but none of …

Sure, Wiles obviously understands the main thrust of his proof. But one could argue that Wiles' result depends on lots of other results, which in turn depend on other results, and …

Tipping is a form of price discrimination, which generally makes things more efficient and has been a staple of capitalism since forever. A business actively wants to extract more …

It does change something. DoorDash's old policy, weird as it is, reduces variability of daily pay for the Dashers. It literally put a derivative structure onto the Dasher pay that …

I think you may be missing the point -- the one being named and maybe shamed in this post is actually Airbnb.

A lot of academic papers actually aren't all that great, for a variety of reasons. Normally, you can use citations, journal, and author credentials to get a sense of whether a pape…

This comparison isn't so great because of the following: for product_id in unique_products: product_items = [x for x in dataset_python if x[0]==product_id ] This is O(unique_produc…

For reference, generally people learn all this over four years of undergrad and probably the first few years of grad school (I have a BS in physics, and a PhD in a different field,…

Sure, and what about skittish Groupon employees?

Right. Airlines overbook because they make more money, and they are bound by laws like "If the substitute transportation is scheduled to get you to your destination more than two h…

This study is suspect. First, using self-identification as high-performance is already troublesome. Second, the author never defines what an HPE is, and the most concrete specifica…

When you get a PhD, you mainly only take classes in your department for the whole time, whereas in undergrad you still have classes in other fields. This usually extends beyond cow…

With pizza, your solution can't work. You have to pay the driver base pay, and they get tips on top. So the base pay has to come from the menu price + delivery fee, and if you get …

Every article on salaries seems to really screw up two things. One is, salary is only a portion of total compensation. Which do they mean here? If you don't look at equity packages…

A philosophy class teaching fundamentals in logic - taught in a way similar to math - is probably more like math in the sense of the article than philosophy in the sense of the gra…

Math classes ramp up in a gradual way that develops critical thinking and intuition in a very small sandbox, where it's easier to appreciate the results. Thinking in, say, just the…
