Yah, have been thinking about this example, too. Even in the US, it’s ludicrous (and dangerous) for consumers to be driving monster trucks in regular traffic.

Years ago read about how the Japanese cell phone industry developed features and standards that could only sell to the local market, dubbed “Galapagos syndrome.”

Unless there’s a dramatic turnaround, seems likely that poor leadership and bad policy are driving US auto industry toward the same fate.

They dressed like a bear and damaged a Rolls-Royce in an audacious insurance scheme A fraud scheme involving wearing bear costumes across Southern California has ended in jail time for three people, according to authorities.

A bear suit laid out on a wooden floor, complete with claws, is part of the evidence that has been used to convict three individuals for staged “bear” attacks on luxury cars for insurance payouts. (California Department of Insurance)

They dressed like a bear and damaged a Rolls-Royce in an audacious insurance scheme A fraud scheme involving wearing bear costumes across Southern California has ended in jail time for three people, according to authorities.

“In an attempt to bolster their story, they even submitted a video of the incident—but it ultimately would be their undoing. Video of the attack shows what appears to be, to the casual observer, at least, a person in a brown bear costume entering a car and rummaging around and pawing at the inside.”

“Since the pollster began asking, the lowest number of Americans that have ever said they like the president personally is 26%, which has been achieved only three times: in the wake of January 6, 2021, in January of 2024, and in March of this year.”

🚨 I have an article out at APR titled “Educational Polarization in American Politics: More than Just a Diploma Divide” in which i look at how educational attainment shapes public opinion and political behavior across the entire education spectrum, not just the across the degree/no degree binary 1/x

Almost every city that boomed after the car grew outward, as if hit with a centrifugal force.

I wonder if newer cities that grow after the mass adoption of e-bikes will return to urban density under a countervailing, centripetal force.

Jury Finds Live Nation Acts as a Monopoly in a Victory for States

“Live Nation argued that Ticketmaster wins business because it is the best ticketing service, not because venues are threatened. But at one point, jurors were shown internal data that indicated fan satisfaction with Ticketmaster had dropped from 18 percent in 2021 to 1 percent in 2023.” Gift link:

Your Glasses Got Worse On Purpose How an Italian orphan built a $27 billion monopoly that controls the brands, the stores, the lenses, and the insurance.

“Alongside a series of surveys published in recent years, these data suggest that there is currently no young cohort within the general U.S. population that can be said to view Israel positively.”

An interactive OJS playground demonstrating a linear congruential generator (LCG) using the formula X_n = (aX_{n-1} + c) mod m. Controls on the left set modulus (m=8), multiplier (a=5), increment (c=3), seed (X_0=1), and numbers to generate (12). A table on the right shows the resulting sequence of X values, intermediate calculations, mod m results, and normalized values X_n/m, with the final "random" numbers highlighted in yellow.

Excerpt from the blog post with R code that tests all seeds from 1 to 10,000 to find which ones produce 10 heads in a row when simulating coin flips. The possible_seeds data frame is filtered to show 10 seeds (614, 1667, 3212, 4166, 4580, 5527, 5824, 7365, 7468, 8975) that meet this criterion. The post notes that seed 614 actually produces 13 heads in a row, confirmed with a withr::with_seed(614, ...) call below.

R console output demonstrating that set.seed(1234) produces reproducible results. The first block calls runif(5) and returns five values: 0.1137, 0.6223, 0.6093, 0.6234, 0.8609. The second block uses the same seed but splits the draw into runif(2) then runif(3), returning the same five values in the same order, showing that the sequence is preserved regardless of how many numbers are drawn at a time.

I've been using random seeds for years but I have no idea how they work. Seeds somehow(?) make the same random numbers?

So I figured it out! New post includes an interactive PRNG generator, lava lamps, lottery fraud, @random.org, Chaucer, and Minecraft #rstats
