Is this subreddit reliable? A cursory read of the comments left me with the impression that human-caused climate change is no big deal, and that makes me wary regarding whether other claims from there are to be counted upon.

Stands to reason that a modified glider will achieve the best efficiency characteristics. That is after all, practically speaking, the raison d'ètre for sailplanes.

This was a very fascinating read and elegantly generalizes some truths that I've been only vaguely aware of. History and warfare is more often in effect a brutal and bloody competition between societies' efficiency. This has impli

I never thought that the ethics of medical research could risk falling prey to the same traps of reasoning that cause short-sighted decisions in business - namely that easily measurable short-term concerns trump greater but less measurable

Almost none of the companies that IPO in the US today have even the remote possibility of yielding a 20X return, never mind 100X or more. At that stage, you'd usually rather want to go with an index fund. Most of the allure of early-

There is a definition in certain stock market indexes of a "small cap company" that actually means "big company". Mozilla is one of those.

This has been my thought since the first time I heard Mozilla was raking in cash with affiliate search. With some planning, they could have had a never-ending income and been beholden to no one. Anyone in here with insight in the decisionma

Yes, all those poor Tesla IPO investors who got misled by a loony are lining up for shareholder lawsuits and yelling for prosecution, due to the obviously financially irresponsible management of their investment. (Refresh my memory here - w

Tesla already changed global transportation, by dragging auto manufacturers kicking and screaming to make real investments in electric transportation. They've averaged a CAGR of 40% or so for the fast decade and have no intentions of

You never ever build railroads again, obviously, and deride everyone that plans building them.

I don't think a country with space capability is seriously considering making orbit useless over censorship. That'd be like shooting yourself in the foot right after you've trained for a marathon, in order to ingratiate yours

Is it possible to somehow isolate the growing units in a way that's both economical, compatible with a degree of automation and also limits cascading failures like disease?

The wipers have 5 modes: Off, 1, 2, 3, Auto. Auto will keep wiping as long as it figures there's water on the windshield. If you want a different speed, you need to go into the touchscreen. If you want a single wipe, you can press the

Hope this prompts them to put the windshield wiper controls on a stalk or the steering wheel. Never been comfortable with that part of the interface.

Don't see why you're downvoted for posting this. Certainly, satellites designed before the Space Shuttle would have to be very paranoidly designed to include a self-destruct mechanism, but it only takes a couple kilograms of explo

Index funds are strongly a momentum investment strategy. I don’t see this appreciated so often. But of course, a properly diversified index fund portfolio contains much more than just the S&P500. Mine has some thousand global stocks, on

Well, inflation is also absurdly low. The direct return on equity, globally, is around 5% for a pure stock portfolio. What is your basis for believing that the safe withdrawal rate will be less than half this, at less than 1.5%? That sounds

Globally diversified low-cost index funds. Meaning not just US, S&P500 etc, but also Europe, developing markets, Nordics, «small cap» (ish) companies. That’s the portfolio I’m using, anyway. No currency hedging and slightly underweight

I'll hazard a guess: PG went out on a limb a few years ago, and actually published a long essay on one of the ideas that are very controversial in the sense implied in this essay. Namely, how tech tools as a primary driver for increasi

I think the central point here is that «assume that» is fine when working with a math problem, but can kill you in real life. If you’ve just lost two billion dollars, or killed 200,000 people in a preventable war, no one cares that the assu

Assuming no great growth isn't entirely reasonable when analyzing a company that has had a CAGR of greater than 50% for the last 8 years, and intends to continue. If you think that's the reality, you should go short in a big way.

Costs 50% more than any. Also inferior range due to 1000 small design & drivetrain details. Can't produce 100,000 of them per year, due to battery sourcing constraints. No global charging network that will make cross-country trips

Musk said a few conference calls ago that Tesla doesn't really have a long-term ambition to make a significant fraction of their profits from S/X. I believe he said "keeping them around for sentimental reasons", which is
