Suggest you put $1000 each into all the other 28m of cryptos tracked by coinmarketcap, "in the slim chance that it completely blew up".

Indeed. The crypto crowd seems to assume that the options for your savings are cash or bank deposits, or crypto. That's nonsense. A balanced portfolio of stocks (with some bonds maybe to reduce vol and improve your Sharpe Ratio) handil

It’s funny how “literally” often means “figuratively” now, and “exponentially” means “polynomially”.

I’m fairly sure the holder of a single private key cannot see the outcome of the election, then withhold the key if they don’t like it. Of course, if they reasons outside the narrow election process (media, gossip) to believe that the outco

Sorry, are you suggesting that Cook doesn't use a computer in his day-to-day work, or has a Windows PC or Linux box in his office? Somehow I doubt that. (It's "macOS", BTW.)

HN is anti-nonsense, anti-hype, anti-crime, so, yeah, pretty anti-cryptocurrency.

Some of those watches from the 1980s onwards ran 5 years on a single battery, or even had solar and need no battery replacement (or recharging) ever. Remarkable.

There was a mode where you'd just cycle through all stored "remotes" until the TV switched off. Then you picked that one, and most likely it would work (in my experience). It was great.

That might be because that product was only available in China mainland, unlike this product which is available in Greater China.

Indeed, before that freak accident the Concorde had 0 hull losses. But even with it, it was not out of the ordinary, that's my point.

by FabHK 1y ago
And just some context on the technological side: 20 Concordes were built, 1 lost, for a 5% hull loss rate. 386 DC-10 were built, 32 hull losses, for an 8.3% hull loss rate. 561 A300 were built, 25 hull losses, for a 4.4% hull loss rate. 157

V1 is the speed at which you can still stop the plane before the end of the runway. (It is computed for each takeoff based on runway length, aircraft mass, takeoff engine power setting, flaps, wind, runway condition, etc.) When the plane re

Seems to me everyone wants to invest, instead, into something that can be "web scale" with low marginal cost, that is, natural monopolies. There is not enough anti-trust enforcement.

Outperformance metric is basically power density. The model described is some 13 kg and delivers 750 kW peak, 350+ kW sustained. (That's 28 pounds, 1000 hp peak, 470+ hp sustained.) The 40% improvement is actually 36% and is versus the
