"number of bytes" is dependent on the text encoding. UTF-8 code units _are_ bytes, which is one of the things that makes UTF-8 very nice and why it has won

What is the actual model that takes 15 seconds to compute? If I understand the setting, you are estimating the demand curve for a given price... And there are only 40 such curves to compute. Surely each curve is fit with only a few paramete

Haskell has genuine mutable memory, through State and IO. But even without it, you can emulate mutation in a pure language by threading a "heap" parameter through everything. There's only at most a log factor of extra space a

If I recall correctly, it's actually possible to implement this in O(n) (or maybe O(n^2)) time and space using a "dynamic programming" algorithm. But in general, Nonogram solving, like most pen-and-paper puzzles, is NP-Comple

What do you mean by "purely with logic, no guessing"? "Guess and backtrack" is a totally valid form of deduction for pen-and-paper puzzles, it's just not very satisfying. But often (always?) there is a satisfying de

Only tangentially related, but just yesterday I learned of Lego's defunct "Modulex" brand, and the serious and apparently widely popular Lego-brick-based project management display boards from the '60s to the '90s.

Yes, although I think it would also clean up the visualization, since you wouldn't have nearly so many lines connecting data centers which actually aren't connected; and it would therefore also be explanatory

Obviously the biggest contribution to latency is distance. But there's also some close-ish regions with poor latency because there's not fiber running directly between them (for example, over the poles) Are there an examples of re

_Earned_ income should correspond to productivity. But unearned income enjoys a dramatically lower tax rate (the capital gains rate is lower than income rate, and capital gains are not subject to FICA/self-employment taxes)

The homicide rate in Japan is extremely low, owing largely to the extreme small number of firearms in the country: approximately 0.2% of the population own firearms (compared to 40% ish of US households) In a country of 125 million, there a

An interesting paper, but some of the other numbers reporting how these catalog sales work are also interesting. Apparently mailing a catalog to 60,000 people will only generate single-digit purchases for each item, with only about 1000 sal

"Vertical" cities are cheaper, healthier, and more sustainable to live in than spread-out suburbs. What makes cities miserable is _cars_, which in most cities are driven primarily by people who don't live there -- since in we

No, it will _never_ be feasible to collect and transport any meaningful amount of carbon out of the atmosphere. We emit 35 billion tons of carbon dioxide every year. That is more than 7x the amount of cement made each year (4.5 billion tons

The USPS is a government agency that already has physical branches in almost every community in the US, which would make it an extremely accessible bank for the 4.5% or so of households who currently don't have a bank. It could also be

No, the default is no access to anything. You have to write rules that allow access to each record in the database. It sounds like the rule that they wrote only checked that the request _is logged in_, because they assumed that visitors can

Good journalists cite their factual claims, even/especially if they're believable. I've never heard of underwater landslides, and I don't think it's a reasonable assumption that a reader knows anything about them.

The main problem is there is simply too much carbon for us to be physically able to pull enough carbon out of the air to make a dent in our emissions. Carbon capture might be able to help if we land on some breakthrough, but it cannot save

Why would you expect the COVID "lockdowns" to meaningfully reduce CO2 emissions? There was no concerted effort to reduce emissions or energy consumption, and in fact the opposite happened. Demand for shipping, including large ship
