note in this that I quoted I said it was the same exact data, but later down in the thread I find that it's per state, the raw data must have been used by the NYT version but it's not easy to find online, so presumably whatever AI agent they used decided it wasn't worth it

anyway the github page is an unfinished version of the website with LLM-generated "fill this in later" type blanks in the README github.com/jenilkansara...

Looking at the .js of the website itself it seems that the answers are stored on a per-state basis rather than a per-city basis like the NYT one, which explains the New Jersey thing, and also implies the maps are just a gaussian kernel on the centroids of the states and...yeah that's how they did it

mydialect.us doesn't do as good a job weighing the statistics. A single question can completely change the look of the map even if it's a minor thing. Like I answered 20 questions and here's if I say "Peas" on Q21 vs "Green Peas" on Q21:

I've found that there's a phantom island in the middle of the Greenland Sea in the GADM database at 80.136°N, 0.018°W. No such island seems to exist irl, so maybe it was a glacier that got scanned? It was messing with some code I was running as it's right in the middle between Greenland and Svalbard

hormuzstraitmonitor.com/ is an example I've come across in the wild. This is a horribly designed website for a lot of reasons, but it's come to be the top search result for "hormuz strait status" when I look that up. It attributes its creation to "an individual developer". Nothing else to learn.
From hormuzstraitmonitor.com/about:
Who Is Behind This?

The Hormuz Strait Monitor is an independent project built and maintained by an individual developer. It is not affiliated with, funded by, or endorsed by any government, political organization, military entity, think tank, or corporation.

The project was created to fill a gap in publicly available crisis information. During the Strait of Hormuz crisis, reliable data was scattered across dozens of specialized sources — shipping databases, energy market feeds, diplomatic wires, and news outlets. This dashboard aggregates those sources into a single, accessible view for anyone who needs it.

The site has no editorial agenda. It presents data as reported by its upstream sources without political commentary or interpretation. Where AI-powered analysis is used (such as for strait status assessments and diplomatic summaries), the underlying methodology relies on real-time web data from established news and maritime sources.

Ideas like the "Trust Dial" for example are clearly pretty half baked. This sort of demonstration would in the pre-AI era have taken quite a while to set up, so the whole thing feels as if it's thought out at first, but in reality it's unlikely they spent more than an hour on this.

This idea gets repeated twice on the about page, but without ever explaining what that means. I still have no idea what they mean by that! If this website was made by a person with a deeper understanding of the project, this would be an important thing to elaborate on, perhaps with its own page.

As far as I can tell, this about page was made by pointing an AI agent at this two page pdf ct-citizens-assembly.org/media/CT-Cit... and asking it to make a webpage advertising the plan. Note for instance this line about reaching 10% of CT's population with AI:

Inter is, I think, disproportionately common here, though it's also been rising in popularity regardless. Fraunces and Space Grotesk are I think the more interesting ones, as I don't remember seeing them until this year, and now I notice them everywhere. Fraunces in particular because of that 'f':

Tell #2 is text, by which I mean both the content of the text (which has a very recognizable voice at this point) and the way it's formatted, including fonts. Below is a list of the fonts I've found to be most common in a sample of 2120 likely Vibe Designed websites:

This isn't because they're using popular style libraries, and the colors used rarely match any others I see used to the exact hex value, it's just a common tendency for them to use blues and purples.

Tell #1 is color, for which each model has a default it tends towards. Claude 4.x almost always goes for a dark blue, while the more recent Claude 5 uses even darker greyer shades closer to black. GPT and Gemini tend to use white with blue or purple highlights.

Anyway, a project I've been on and off typing up over the past couple months is a big list of all the basic web design elements that in my opinion give away a website as having not been designed by a human. I've enumerated these as "The 5 Tells of Vibe Design":
A list of the five tells with screenshots illustrating each.

The tells are:
1. Colors (shown with a site with a dark blue color palette)
2. The Text (a site with many emoji and AI generated copy)
3. CSS Styles (the twitter.now page, with characteristic rounded rectangles and left-border elements)
4. Design Priorities (a site that uses a dashboard format to display inane details prominently)
5. The Creator's Relationship to the Product (a site whose domain registration has lapsed)

Geobica @geobica.com · 28/08/2026
the main indication is of course the fact that it's a grift asking for ≥$20 with AI generated copy and AI generated icons, but there is a lot about the CSS styling and structure of the site that also gives it away to me

Turnout was certainly higher in places with other elections (36.31% of 2024 for x>0.9 vs 28.71% of 2024 for x==0) but the main trend is just that more Dems turned out across the board.

On the right is a big blob that fits what Mary Radcliffe was describing, but her hypothesis is wrong; These aren't democrat areas. All the precincts with x>0.9 together voted 56.42% for Trump in 2024, whereas they went 55.90% for *democrats* in this year's PSC elections, a D+12.32 point swing.

I looked at two metrics: 1. What was the ratio of turnout in for the PSC races vs the highest turnout for any other race in that precinct in 2025? (x-axis) 2. What is the ratio between the highest turnout for any race in the precinct in 2025 and the 2024 presidential turnout? (y-axis)

So I downloaded some precinct level data from results.sos.ga.gov/cdn/results/... to compare with the 2024 presidential results from github.com/21MetcalfJ/2... A lot of precincts have either changed names or merged/split, so I don't have the exact correspondence I'd need yet, but most are the same:

I was inspired to make this by the fact that I couldn't find one quite like it, though admittedly I didn't search that long. This was the best I found, though it fudges the numbers a bit to account for the fact that the systems use averages over different numbers of minutes of sustained winds.

However, the 2016 article (Aguiar et al.) isn't the origin either, and it references another document from 2003. scielo.sld.cu/scielo.php?p...
En Cuba, se reporta una incidencia de 2 a 4 por cada 10 000, aunque según afirma Ravelo, V. "existe la posibilidad de que las cifras sean mucho más bajas que los actuales reportes de hasta uno por 100 de todo el espectro que en algunos países se estiman, pues es cierto que el aumento del reporte para algunos está dado por el mayor conocimiento que del trastorno se tiene, así como la diversidad en las definiciones, los sesgos estadísticos etc., lo que hace parecer que realmente hay más casos".2

Searching for this alleged study brought me to Hernández-González et al. (2022), which contains these figures in the introduction, but sources that from a 2016 article. www.mdpi.com/2227-7102/12...
 1. Introduction
Autism spectrum disorders (ASD) encompass a group of neurodevelopmental disorders that appear in the early stages of life, and they are characterized to variable extents by difficulties in verbal and non-verbal communication, reciprocal social interactions, and restricted or repetitive behaviors [1]. In recent decades, the prevalence of ASD has grown exponentially [2]; for example, an incidence of 2 to 4 per 10,000 is reported in Cuba [3] and at international level there is a global autism prevalence that ranges within and across regions, with a median prevalence of (screenshot cuts off there)

Geobica @geobica.com · 01/10/2025
The article claims that there exists a "2022 study" that shows "an autism incidence of about 2 to 4 per 10,000 children" in Cuba, which would be significantly less than the US in 2022. However, these numbers aren't from 2022.
According to a 2022 study, Cuba had an autism incidence of about 2 to 4 per 10,000 children in some settings. While research on autism diagnoses in Cuba is much more limited than in the US, the data from the 2022 study shows a far lower rate of recognised cases than in the US – despite the presence of acetaminophen.

A bunch of rivers especially in Quebec had their source listed as being in the eastern hemisphere by mistake. Checking Doucet River, for example, this still has not been fixed. Perhaps I should regather this data to fix it.

Another note: While the common depiction of baby ducks is as yellow, this more closely resembles the goslings of the embden (right) than the ducklings of a mallard (left):

Aside from the baby ducks, duck clipart is mostly male mallards, while the common archetype in goose clipart is the domesticated embden breed. Presumably this became the cultural association because of these species' presence throughout Europe.
