I think the fun/hobbyist/urbanist answer is that people just like to know facts about where they live, I've spent hours now looking up different places' data. The more commercial a…

I'd like to! It'd be pretty straightforward for the parts based on OpenStreetMap i.e. generating travel time areas / points of interest, I'd just need a bigger database. Ingesting …

I've been building a bunch of US geography tools/games/visualizations and thought folks on HN might like this one. There are also drive-time and bike-time tools available on the sa…

Yep, street view is not working at all for me

It seems silly to expect someone to read the whole book before evaluating it when the creator didn't even read the whole book before publishing it

It seems that Slack being fully down and unusable only reaches the "incident" category on their scale - I'd hate to see what counts as "outage"

I think the core problem at hand for people trying to use AI in user-facing production systems is "how can we build a reliable system on top of an unreliable (but capable) model?".…

It seems like he did everything! I first heard of Von Neumann in international relations & economics classes as the person who established game theory, then later in CS classes as …

Easy way to get a fair result from an unfair coin toss: Flip the coin twice in a row, in this case starting with the same side facing up both times, so it's equally unfair for both…

Reminds me of a cool proof I saw recently that there are two numbers a and b such that a and b are both irrational, but a^b is rational: Take sqrt(2)^sqrt(2), which is either ratio…

When my primary care doc referred me to a dermatologist for a suspicious mole, I could not find an actual dermatologist who would see me in less than ~8 months. I ended up seeing a…

This article really resonates with me - I've heard people (and vector database companies) describe transformer embeddings + vector databases as primarily a solution for "memory/con…

Source code and more info here: https://github.com/votermap/votermap.github.io/tree/main The core idea is to take precinct-level election results and visualize them with one dot pe…

I think something with the "wow" factor of the Vision Pro but the form factor of a pair of glasses would be the holy grail of AR/VR. I wonder if there are fundamental tradeoffs whi…

I made this script because I was using ChatGPT voice mode as a janky implementation of this concept a while ago and found it really useful for building my Spanish vocabulary, and h…

The US Census publishes block-by-block population & housing data[1], and I couldn't find an online map of this, so I built one. It also includes lots (10k+) of other indicators pub…

I bought the short-story collection this is a part of and liked it a lot: https://qntm.org/vhitaos A lot of the stories are free to read online without buying it but I thought the …

I just made an update which should enable "population density" type queries to work a bit better - there is now an option to divide by 'LAND_AREA' for any variable (though this sho…

Thanks for trying it out - adding land area and supporting queries like "population density" will definitely be doable, and I'd like to make the legend and map color scheme a bit b…

Hi - thank you for trying it out! These are both definitely real issues with the current approach. I've tried to reign in the "selecting an overly specific table" issue in the fina…

The core idea here is to use semantic search & LLMs to make it easier to search the tens of thousands of different demographic indicators available from the US Census API. I'm defi…

This lines up with how I make tech stack decisions for my own projects. But I think it's not always obvious going into something if it's going to end up being a money-making endeav…

That upstream provider being Snowflake, according to this article: https://www.hudsonrock.com/blog/snowflake-massive-breach-acc... (posted on HN here: https://news.ycombinator.com/…

This article is claiming that the Ticketmaster breach from a few days ago was actually a much broader hack affecting 400+ companies, all through a Snowflake employee's stolen crede…

Looking over the specifics, the striking thing about this to me is that it seems like these supposedly-sophisticated covert operatives are just going to ChatGPT (or similar) and ba…
