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 it's reasonable to prefer cash n

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 find 15 minutes of meeting time

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? Doing a basic google search led me to https:/&#x2

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 acknowledge this as a crime or extradite? What if the rockets a

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: https://github.com/0xNF&#x2

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 plane is 14h40m by train -- and 8h by car. Maybe by get

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 professional analysts. Secondly, sure, maybe you can see how great yo

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 evaluation' technique (let's just leave that as magi

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 the practical details you're referring to.

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 so on through decades and decades of work, ultimately

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 money from customers who can afford more, and still sell to

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 reduces volatility -- the pay was cash plus a call op

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 paper is even worth skimming. The only "paper"

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_products * observations), and it looks like

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, so not 100% sure on the grad school work). That's 6 y

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 hours later (four hours internationally), or if the air

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 specification is from this article they backlink to: >For ex

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 coworkers into friend circles too. This isn't math speci

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 rid of the delivery fee, it has to come from the menu

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, my intuition is you're going to think SF suck

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 grandparent post. The grandparent probably meant something mor

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 x-y plane makes it far easier to isolate relationship

Pytz handles a certain class of funkiness in TZ changes, but not the one mentioned here. Consider, a user in footopia enters a datetime 3 months from now which is saved in UTC in your database. Then footopia changes their TZ definition.

Sure, I forgot the self-join case. In my experience these are a minority of joins, but definitely. In postgres at least, a lot of self-joins can be solved with a DISTINCT ON instead. Sub-selection with a FROM clause, yeah, those definitel

Weird, I really dislike a lot of the suggestions. In particular, an example: SELECT first_name AS fn FROM staff AS s1 JOIN students AS s2 ON s2.mentor_id = s1.staff_num; We already agreed that staff is a good name for

In this instance, Uber is making public transportation _more_ accessible. They are crowding out people driving from home to a parking lot. Anyway, the article mentions this is maybe ten to a hundred rides a day. This is either a PR thing

This article just rambles, and I'm not really seeing what point it's trying to make. Point one, I think: something about inequality because DSC has 190 employees. But it still takes the same order of magnitude number of people to
