Comment Re: do not want (Score 1) 202

I have just bought a new set of EV tires (with sound-deadening foam) for my Model 3. They came up to $310 per tire with installation. A slightly cheaper set was $260 per tire.

So you're looking at maaaybe paying $400 extra per the set of tires, and you need a new tire set every 30000-40000 miles. I think that's pretty much negligible.

As far as I can tell, in terms of functionality, it's a huge step backwards. XWindows is a system that lets you open user interfaces from remote machines and onto remote machines, an amazingly useful trick that some idiots didn't bother to put in its "replacement". So even though Wayland performs better, IMO, you wouldn't want it. I know I don't.

Comment Re:Only to investors, right? (Score 2) 28

Technically speaking the crime of fraud has three elements: (1) A materially false statement; (2) an intent to deceive the recipient; (3) a reliance upon the false statement by the recipient.

So, if you want to lie to people and want to avoid being charged with fraud, it's actually quite simple. You lie by omission. You distract. You prevaricate (dance around the facts). You encourage people to jump on the bandwagon; you lead them to spurious conclusions. It's so easy to lie without making any materially false statements that anyone who does lie that way when people are going to check up on him is a fool.

Not only is this way of lying *legal*, it happens every time a lawyer makes an closing statement to a jury. It's not a problem because there's an opposing counsel who's professionally trained to spot omissions and lapses of logic and to point them out. But if a lawyer introduces a *false statement of fact* to a trial that's a very serious offense, in fact grounds for disbarrment because that can't be fixed by having an alert opponent.

We have similar standards of truthfullness for advertising and politics because in theory there's competition that's supposed to make up for your dishonesty. In practice that doesn't work very well because there is *nobody* involved (like a judge) who cares about people making sound judgments. But still, any brand that relies on materially false statements is a brand you want to avoid because they don't even measure up to the laxest imaginable standards of honesty.

Now investors have lots of money, so they receive a somehat better class of legal protections than consumers or voters do. There are expectations of dilligence and duties to disclose certain things etc. that can get someone selling investments into trouble. But that's still not as bad as committing *fraud*, which is stupid and therefore gets extra severe punishment.

Comment Re: 20% survival is pretty good (Score 1) 57

If I understand your argument properly, you're suggesting that things will be OK with the reefs because "survival of the fittest" will produce a population of corals better adapted to warmer conditions.

Let me first point out is that this isn't really an argument, it's a hypothesis. In fact this is the very question that actual *reef scientists* are raising -- the ability of reefs to survive as an ecosystem under survival pressure. There's no reason to believe reefs will surivive just because fitter organisms will *tend* to reproduce more, populations perish all the time. When it's a keystone species in an ecosystem, that ecosystem collapses. There is no invisible hand here steering things to any preordained conclusion.

So arguing over terminology here is really just an attempt to distract (name calling even more so) from your weak position on whether reefs will survive or not.

However, returning to that irrelevant terminology argument, you are undoubtedly making an evolutionary argument. You may be thinking that natural selection won't produce a new taxonomic *species* for thousands of generations, and you'd be right. However it will produce a new *clade*. When a better-adapted clade emerges due to survival pressures, that is evolution by natural selection. Whether we call that new clade a "species" is purely a human convention adopted and managed to facilitate scientific communication.

You don't have to take my word for any of this. Put it to any working biologist you know.

I won't return in coin by calling you an idiot, because I don't think you are one. What I think you are is too *ignorant* to realize you're talking about evolution. "Survival of the fittest" is a phrase coined by Herbert Spencer in 1864 to refer to natural selection, a concept that's in the actual *title* of Darwin's book.

Well, no *one* of us in a position to save the coral reefs. Not even world leaders can do it. But we *all* are in a position to do a little bit, and collectively all those little bits add up to matter.

Sure if you're the only person trying to reduce is carbon footprint you will make no difference. But if enough people do it, then that captures the attention of industry and politicians and shifts the Overton window. Clearly we can't save everything, but there's still a lot on the table and marginal improvements matter. All-or-nothing thinking is a big part of denialist thinking; if you can't fix everything then there's no point in fixing anything and therefore people say there's a problem are alarmists predicting a catastrophe we couldn't do anything about even if it weren't happening.

As to the loss of coral reefs not being the worst outcome of climate change, that's probably true, but we really can't anticiapte the impact. About a quarter of all marine life depends on coral reefs for some part of their life cycle. Losing all of it would likely be catastrophic in ways we can't imagine yet, but the flip side is that saving *some* of it is likely to be quite a worthwhile goal.

Of course this isn't science, it's just wishful thinking and hand waving about things you don't actually know much about. It's probably worth noting that actual reef scientists aren't so cheerful about the prospects for coral reefs as you are.

It's not even that what you *think* you know is necessarily wrong. You're talking about about something reef scientists aren't particulary worried about: the extinction of coral *species*. In other words it's a straw man. What scientists are worried about is something quite different: a massive reduction in the 348,000 square kilometers of coral reef habitat that currently exist.

That's something that will take millions of years to recover from, and which will cause countless extinctions It will result in multiple species extinctions; sure that's survival of the fittest, but "fittest" doesn't mean "better"; it means more fitted to specific set of new circumstances, in this case circumstances we *chose to create*. And sure, in a few million years it won't matter. But that's not the test we use to decide whether anything other issue needs addressing. If someone broke into your house and took a dump on your kitchen table, it wouldn't matter in a million years, but you'd sure report it to the cops and expect something to get done about it.

No, it's not evolution *at work*. It's human intervention in the environment at work. Sure, evolution will *respond* to this intervention; if you want to see *that* at work, go into suspended animation for a hundred thousand years.

You could argue that *humans* are part of nature and therefore anything we do is natural. That's just quibbling. By that argument it would be just as natural for us to choose not to shit in our own beds.

Turbotax offers free service to low-to-moderate income people as part of an agreement it has made with the IRS. In return for this, the IRS doesn't provide free electronic tax preparation services like most other advanced countries do. For most consumers, the IRS could in fact automatically fill out their returns and the consumer could simply check it by answering a few simple questions rather than puzzling over instructions written for professional accountants.

If you've always wondered why filing your taxes couldn't be simpler, a bit part of this is marketing from companies like Intuit that make a lot of money out of simplifying the process for taxpayers.

The free tier service is something Intuit is contractually obligated to provide. Upselling low-income people to a paid service that wouldn't benefit them in any way is morally dubious at best.

Comment Flywheel storage (Score 4, Interesting) 169

What I wonder is why flywheel storage isn't a popular alternative to batteries for fixed installations. Creating heavy flywheels isn't hard, nor does it require the kinds of toxic materials used in batteries. Tungsten carbide with a steel casing anyone? Mount them on good bearings and you should get >90% efficiency from them, and I'd guess the energy density should be higher as well. I'd have to do some calculations to see if units small enough for home installation would have enough capacity to be useful for a reasonable length of time, but large-scale industrial/commercial installations should be.

No. The timescales are on the side of my argument. The diameter of the Milky Way is about 100,000 light years.

If just one alien civilization figured out how to travel at 1% the speed of light from Star to star, it would take about 10 million years to expand from one side of the galaxy to the other. That is a very small length of time, because if life is common enough for there to be, say, hundreds of civilizations developing in the galaxy, over its billions of years of history, then the spread of their beginnings would most likely vary by far more than just 10 million years.
