I prefer Simon Tatham’s version[1]. It’s free, and configurable, and available online, and multiplatform. But the best thing about it is that you can always win, if you use deduction. As such, it’s more a puzzle than a game of chance. 1.

Don’t read the book. Listen to it. I got a lot out of listening to a performance of the book, by Irish actors on RTE. It’s a lot more fun than reading the book. There’s a podcast for it: https://www.rte.ie/culture/2

There are several kinds of skin cancer: carcinomas (which don't usually kill you) and melanona (which does). Carcinomas are indeed positively correlated to sun exposure, but oddly enough melanoma is negatively correlated: sun exposure

Another thing that’s changed since young boomers roamed the earth is soil depletion. Decades of farming the heartland in the US midwest have used up all the zinc and boron and other minerals in the soil. If you consult the USDA food table

Yet another sign of how a great city has declined over the years! When I lived in Montreal in the 80s, it was the car theft capital of the country. Now that title belongs to Toronto. In case you hadn’t heard, car theft is so bad in Toront

Of course Simon Tatham’s puzzle collection includes this one. He calls it “rectangle”. You can configure the game to leave spaces around the numbers, which increases the difficulty. There’s a web based version here: https://ww

The problem is that fentanyl is very strong, and drug traffickers have very poor quality controls. The LD50 is 0.03 mg/kg in monkeys, so if humans are like monkeys, a 70 kg human has a 50% chance of dying after ingesting 2 mg of fenta

When I studied group theory, I would have been so much happier if someone told me we were talking about nonzero numbers, or invertible matrices, or functions. A little of bit of concreteness would have helped enormously to motivate the top

The FCC used to have a "fairness doctrine." If a network had a broadcast license, it was required to present controversial issues in a balanced manner, presenting different points of view. This meant that the news segments were

I think you’re conflating two things that are different: factory farming, which is run by huge agribusiness companies, and eating meat. Small farmers can also raise animals for meat consumption, and they can probably do it on a smaller sca

I’d be worried about excessive iron intake from a cast iron pan. Too much dietary iron can cause all sorts of problems. How about enameled (glass coated) pans instead?

Simon Tatham’s “untangle” puzzle[1] does this, with randomly generated planar graphs. If you ever find yourself being too productive, download his puzzle collection ;-) 1: https://www.chiark.greenend.org.uk/~sgtatham/pu

Brain bleeding is very rare. That 38% number is a *relative risk ratio*. I'm always wary of studies that use such ratios to make an effect seem large. The following excerpts from the article you cited state: For the study, the resea

Debt slavery was not life-long. Leviticus 25:8 requires that slaves be freed on Jubilee years, which occur every 7 years. That's the origin of modern laws on discharging bankruptcy after 7 years (bankruptcy comes with a penalty, beca

The divisiveness that's everywhere in the US political system is a feature, not a bug. By casting political problems in terms of tribal loyalty, you can get the voters in your tribe to ignore deeper problems. The deeper problems are,
