It's early in the year. You want to drive straight through the middle of Chinatown in SF. Why might that be a bad idea?
I feel like a Google Maps-style system would discover this automatically by noting via phone location data that there is heavy traffic in Chinatown.
(I do get the author’s point, but I think that factually this example would not be a problem)
Wow, it seems like this might beat out flite for very-low-memory TTS? I ended up abandoning a project of mine because I couldn't get high enough quality or low enough memory usage out of flite, so I'm very excited to try this out.
Flite for comparison: https://github.com/festvox/flite
The part that confuses me is that they use “it” to name a variable that is not actually an iterator. That’s very bad style. I would name it “s”.
This is awesome. Congrats on shipping!
The nearest thing that I've heard of is Wolfram Alpha's step-by-step solution solvers, but the worry with those is always that it's too easy for the student to just keep clicking next step and not learn anything.
I appreciate how this frames algebra as a puzzle instead of a problem :)
The Wolfram thing: https://www.wolframalpha.com/examples/pro-features/step-by-s...
Specifically this one: https://www.wolframalpha.com/input?i=find+t+for+t%5E2+%2B+3t...
It's a question of "value created" vs "value captured". They captured about as much value as the risk-free rate of return.
Value that is created but not captured (e.g. the value of consumers enjoying games and consoles above and beyond the price that those consumers paid) is typically not considered when making business decisions.
He is prolific!
Thank you for sharing your site as well :)
Stories are stories, man. Story-logic is biased towards interesting tales.
Also known as the fallacy of “generalizing from fictional evidence”.

It seems like this cell barely evolves, because the system they built for duplicating the DNA makes very few errors.
Natural life tends to evolve, which may have consequences for production.
For example, quorn production has to be restarted from a seed population after ~1000 hours because it tends to evolve colonial variants that break the product standards: https://www.davidmoore.org.uk/21st_century_guidebook_to_fung...
This is the first that I'm hearing about this, but I don't think that your telling is quite right. The Dallas school district is "Dallas ISD", not Dallas County Schools.
Dallas County Schools was apparently a school bus service provider that served many different school districts in the area. I don't know why they named it that...
https://en.wikipedia.org/wiki/Dallas_County_Schools
That situation looks pretty bad, but what happened was that a public school bus services provider went bankrupt, the school districts that it served became responsible for finding private replacement service providers, and residents of the service area had their property taxes raised to pay off the debt.
No school districts went bankrupt or were split up, just school bus service providers.
Done. That was quite interesting, although I see what you mean. I did skip over some of the sections about how to teach concept maps to elementary school students and some of the examples given.
I think my conclusion is that he's probably right that producing and discussing concept maps is the fastest way to share and validate conceptual understanding, so I'll add them to my toolkit.
I'd never heard of the Gowin's Vee chart before (the other main topic of the book) and it seems useful although I can't realistically see a situation where I'd personally use it. There are quite a few similar "planning process" or "research process" systems that cover similar ground. I do like how this one is relatively "zoomed out" to make sure first-and-foremost that your investigation is actually answering some meaningful question within your wider cognitive context.
which TBH is so dry I'm not sure anyone I've recommended it to has actually finished it :)
Challenge accepted!
That is cool, although it took me awhile to understand it because the posterior probability is on the left and the prior probability is on the right, and because it uses D=Disease and T=Test when I am used to seeing D=Data.
Since PCA maps are fun to look at, here’s one for modern-day populations:

This made me smile because I did exactly the same thing (i.e. I also read Anna Karenina in 7th grade, and was very pretentious). I mostly read during lunch periods when it probably would have been a better idea to be developing my social skills.
I remember being most interested in Konstantin Levin's efforts to modernize his farm estate.
I think that at the time I thought that I understood the difficult books that I was reading fully, but looking back on it I must have missed so much. I'll need to have a re-read one of these days.
I just skimmed the summary but in the results section it reports three significant results and two after “multiple-test correction”. I’m not sure how they did that correction; I would expect that measures of cognitive performance are correlated for each child and so the standard Bonferroni correction might be too harsh to apply here.
Covariate-adjusted analyses of standardized scores (mean [SD], 0 [1]; higher values indicating better performance) showed positive associations of high-dose vitamin D3 with verbal memory (β = 0.17 SD; 95% CI, 0.03-0.32 SD; P = .02), visual memory (β = 0.24 SD; 95% CI, 0.06-0.42 SD; P = .01), and flexibility or set shift (β = 0.19 SD; 95% CI, 0.01-0.37 SD; P = .04); however, high-dose vitamin D3 was no longer associated with flexibility or set shift after multiple test correction.
It seems to be a real definition, see definition 6 under etymology 2:
(transitive, law, especially New Zealand)[1] To subject [someone] to a trespass notice, formally notifying them that they are prohibited from entry to a property, such that any current or future presence there will constitute trespass, (especially) criminal trespass
There’s always the extra idiomatic __SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED for coworkers that can’t take a hint.
I typically do the same algorithm for each solution, but I do try to write it in an idiomatic way to each language.
I usually look at the editorial after the first solve to see if I missed any tricks or other approaches, and sometimes I’ll write the second solution differently if there was something interesting that I missed.
It's a feature of the leetcode.com website. I actually can't find a URL that will directly link to the current day's problem, but you can open https://leetcode.com/problemset/ and select the current date in the calendar widget (at the top right on desktop, or by clicking the green calendar floating action button at the bottom right on mobile).
You can view the daily problem without logging in or creating an account.
Fair warning: today's daily problem is a "hard" difficulty and it is often worth skipping those or peeking at the solution. They can take a while to solve (often at least an hour) and/or rely on unusual tricks or data structures. I haven't solved this one yet so idk exactly what its deal is.
Good question. I chose them because they are the languages that I use professionally and would choose for technical interviews. I expect to be asked to solve problems in either language in any given interview.
Technical interviews are different enough from day-to-day work that I still find it valuable to practice in them.
I think that it helps a lot to have a daily practice of using a language for small things.
In much that same way that many people do the daily wordle or crossword, I do the daily leetcode.
I flip a coin and solve it first in either C++ or Python, then re-write my solution in the other one.
Usually it takes me around 20 minutes to solve it in either language, and 5 minutes to re-solve it in either language.
Recently I decided to start learning emacs lisp. This is an imperative lisp dialect that’s pretty different from scheme, but I think that the particular language doesn’t matter much for this process. I could a bit biased because I do have prior experience with SML and scheme.
I started re-solving the problems a third time in emacs lisp. And I’m still learning but I’ve felt my comfort with the language increase over time, and I expect that if I continue doing this then I will eventually reach parity with C++ and Python.
Currently it takes me about 20 minutes to re-solve a problem in emacs lisp, because I usually have to read documentation and/or look up something new.
Some context is probably necessary for this submission. This is a direct link to one chapter of a book-length (1905 pages!) suicide note titled "Suicide Note" by Mitchell Heisman, who committed suicide near Harvard University in 2010, ostensibly because he convinced himself that non-existence is morally equivalent to existence.
This chapter discusses the Singularity and in particular the idea that God is a technology that has evolved under selective pressures alongside human societies, and that we will eventually create an actual AI God as a continuation of this process.
I think that it's interesting as a standalone read and relevant for discussion on HN. I was surprised to find that it had never been discussed here before.

This is called being a “universalizing” religion.
The big three universalizing religions are Christianity, Islam, and Buddhism.
You can understand a lot of religious history as just those three religions expanding and displacing other belief systems.
Contrast with non-universalizing religions like Judaism, Hinduism, and Shinto.
You honestly just have to treat any Oracle product as malware, and proactively scan for it / block it from being installed on employee laptops in the first place.
gwern once ran a rigorous N=1 self-experiment on magnesium with self-blinding and week-long blocks, and concluded that it was probably helpful to him: https://gwern.net/nootropic/magnesium#conclusion
You are welcome to review his methodology and see if it still seems like the placebo effect.
I have a monthly recurring task in my task manager to open the Dropbox app on my iPhone and leave it in-focus for a couple of minutes while it uploads the previous month’s photos.
If I don’t do that, then it just won’t upload them.
Canvas is actually also open source and can be self-hosted: https://github.com/instructure/canvas-lms

I read the first link and was curious what the outcome of the case was, since the article was released in 2021. It seems that Jeanne was declared alive again in 2023, which is the most recent public reporting on the case:

Trader Joe's is probably closest to what you want. It targets single shoppers with small quantities and low prices, and it rotates products frequently to keep things interesting.
Anecdotally I feel like a lot of TJ's shoppers shift into Costco shoppers as they age up.
