Personal dashboard for Costco spending

2025-12-04 22:59:16

Reddit user ViKoToMo scraped Costco receipts from his account and made a dashboard that shows spending for the past two years.

This short script by Ankur Dave was used to access Costco receipts. I’m not sure how long that’s going to work, but there you go, in case you also would like to see how many thousands of dollars you spend on organic chicken thighs, bananas, and street tacos.

Towards zero traffic fatalities

2025-12-03 20:12:02

Speaking of traffic fatalities, Helsinki is doing things differently. Amanda Shendruk for Not-Ship has the charts:

This past summer, Helsinki made an astonishing announcement: as of August, the Finnish capital went an entire year without any traffic deaths. Not a single pedestrian, cyclist or driver died on the city’s roads. Not. One.

And this wasn’t an outlier year. Helsinki’s traffic deaths have been steadily declining for decades.

Lower speed limits and income-based speeding fines helped the city get to this point. Maybe others should give this a try.

Sidenote: Not-Ship is a new data-focused newsletter from Shendruk that is worth a sub.

Mapping the most dangerous intersections for pedestrians

2025-12-03 19:47:25

For the Washington Post, Ian Duncan, Emmanuel Martinez, and Dylan Moriarty analyzed traffic fatality data from the National Highway Traffic Safety Administration:

The Post analysis documents, for the first time, a sharp increase in places with clusters of pedestrian deaths, revealing the deadliest neighborhoods and stretches of road in hundreds of cities. The number of locations with at least three recent pedestrian deaths clustered within a mile of one another tripled during this period, from more than 275 in 2010 to more than 825 in 2023, The Post found. Those hot spots increased most in states in the southern half of the country such as Tennessee, North Carolina and Arizona.

A searchable map lets you see incident counts in places of interest, which is unsettling when you see dots and hexagons not far from where you live.

Who earns a higher salary than you and the jobs they work

2025-12-02 19:49:42

Is your salary high, low, or somewhere in the middle? What do people with higher salaries than you do for a living? Doctors, lawyers, and tech workers come to mind, but there is a wider range of occupations, depending on the income level you’re comparing against.

Growing political contributions from billionaires

2025-12-01 20:24:05

The Washington Post examined political contributions from the 100 wealthiest Americans, which have shown big swings the past few years.

What changed? Republicans long characterized Silicon Valley as a bastion of liberalism. But over the past half-decade, many of tech’s wealthiest titans rebelled against the Biden administration’s criticism and policing of their industry. Last year, many tech barons threw their support behind the GOP, which they saw as more aligned with their often-libertarian ideals and their companies’ economic interests. Trump and his party actively wooed influential tech leaders, embracing cryptocurrency and promising to limit AI regulation. His vice president, JD Vance, formerly worked as a venture capitalist in San Francisco, forging ties to Thiel, former Google CEO Eric Schmidt and venture capitalist Marc Andreessen.

It’s all about the money, as usual.
