Let's run through the likelihood of seeing multiple flips on the same piece of data. Google's research [1] finds a DRAM error rate of "25,000 to 70,000 errors per billion device hours per Mbit" on hardware in "moder

As far as I know, all of those syndicates are out of business after the lottery retired the Cash Winfall game. (And yup, that's me. I could probably make my HN bio a little more explicit on this point.)

It's too bad the article doesn't go in more depth. There are a few plausible explanations for why people claim an unusually high number of prizes: 1) Someone is buying a huge number of tickets, and just winning proportional to the

One plausible explanation would be if Teslas logged more miles than comparable cars. If I drove more, I'd be more inclined to spend money up front for a more fuel efficient (and more fun to drive) car. And on the flip side, if I drove

This website seems to post articles about what happened 100 years earlier, and the URL says 2015/7/20, so I'd assume it's talking about July 1915.

I feel like the longer games (in both cricket and chess), because they're often so tactical and slow-paced as to be yawn inducing, have a greater payoff when they do suddenly turn exciting. (See the final day of this past week's N

I'd imagine it depends on the "bootcamp." It seems like many of the more reputable ones don't charge tuition and make their money on referral agreements for successful placements.

It's interesting to hear this. I used FlightCar (as a renter) quite a bit in its early days (2013) and at that time the customer service was unbelievably great, to the point that I actively preferred FlightCar over other rental car com

There's a thrill in figuring out a system, and there's some satisfaction in optimizing and executing it, but for the most part, if you're doing it right, being a professional gambler is pretty boring.

I assume you're thinking about the earthquake risk. We haven't had a major quake here in a generation, and people have short memories. The San Andreas fault exists day-to-day as a pretty chain of lakes. I'd also count being i
