Comment Re:I look forward (Score 2) 137

Actually, I don't know why they don't "acquiesce" somewhat to the demands - and offer to sell to the dealers at the same price as they sell in other states.

I don't think there is anything stopping a Texas auto dealer from going to Tesla's web site today and buying as many cars as he wants to buy.

The real issue is that the dealer would then want to service and support these cars, which would require a more in-depth working relationship with Tesla; and Tesla (quite reasonably IMO) does not trust dealers to do as good a job with that as Tesla itself can. Without quality service and support, OTOH, there is no reason why a customer should want to buy through a dealership and pay extra for inferior support.

The weirdest thing is that this hatred of "government" seems to come, without a trace of irony, from politicians.

It's perfect cover: as an anti-government politician, if your policies don't work, that's only more proof that government is incompetent and you were right all along to oppose. If they do work, OTOH, you're a hero! You can't lose :^)

Comment Re:Why program in Python (Score 1) 277

Also, explain to me why anyone should use an interpreted programming language when even CommonLisp was already compiled in the 80s?

In a large number of scenarios, the limiting factor is the skill of the (often easily-intimidated newbie) programmer, not the speed of the resulting program's execution.

In those cases, a "slow" language that is easy to learn and use (e.g. Python) typically produces a better result than a really fast/powerful language that isn't as newbie-friendly. Computers are fast enough these days that for a lot of things, a slow/inefficient program is nevertheless more than adequate to the task at hand.

In particular, I think the ability to run the Python interpreter and enter python code into it interactively is an easy and convenient way for people to experiment and learn how Python works. Compiled languages make that harder to do, as you have to enter all your changes at once, then recompile, rather than being able to type in a single line and get an instant result.

Comment Re:C/C++ at $160k/yr (Score 2) 277

Which language is that? Phython? C++? C? Java? A language "does not cut it" ... how retarded.

It's not retarded at all; it's a simple fact that each language comes with its own set of design decisions that make some tasks easier and some tasks more difficult. Thinking that all languages are equivalent would be a newbie mistake.

For example, Python, while it is a great high-level language and easy to learn and use, will almost never produce software that runs at the speed of an equivalent compiled C or C++ program. Furthermore, its continuing reliance on a Global Interpreter Lock means that multithreaded Python programs will not utilize multiple cores efficiently for the forseeable future.

Java, OTOH, avoids those problems but using Java means you'll need to include a Java runtime environment and JIT on any platform you deploy on; that makes it inappropriate for many embedded devices or otherwise constrained environments. Also the non-deterministic timing of the built-in garbage collector makes Java a poor fit for real-time programming.

C/C++, finally, can run mostly anywhere, but their low-level nature makes them a bit harder to learn, and a great deal more conducive to shooting yourself in the foot with (if you don't use them correctly).

As soon as too many people start putting power from solar back onto the grid at one time, in one area? They can't really do anything with it, so it gets wasted.

A possible twist on this outcome: before this happens, the price and performance of energy storage (e.g. electric-car style battery packs) improves to the point where it becomes economical for most solar panel owners (or perhaps even the power company) to store any excess electricity that would otherwise be wasted. Dunno if or when it will happen, but it certainly would simplify things.

Comment Re:obviously they should track the sun (Score 1) 327

A system that moves the panels shouldn't add that much to the cost and will probably pay for itself very quickly with the extra energy collected.

I'm not so sure about that -- anything with moving parts is liable to wear out and need expensive repairs. I certainly wouldn't expect it to last anywhere near the 20-25 years that the rest of the system will. Given enough space, it's probably cheaper and easier just to buy more fixed panels than to add motorized sun-tracking equipment.

Straight out of Agenda 21. Stack-and-pack all the people, allow ownership and taxation of property, but control usage from a central authority, and slowly ban development, and eventually humans entirely, from the vast majority of land.

As the human population approaches the planet's capacity, such authoritarian measures are going to proliferate, if only because the alternative is economic failure and societal collapse.

In a sparsely populated, open system (e.g. the Old West), there are effectively unlimited natural resources, so no formal resource management is necessary. Libertarian/individualist principles work fine there, as what group A does or doesn't do to the environment has limited effect on group B, who (in the worst case) is always free to find a new plot of land to live off of.

In a submarine at sea, at the other extreme, resources are extremely limited, and everybody depends on everyone else to keep the environment stable. Bad actors cannot be tolerated. Therefore, in submarines you will find only very authoritarian social systems, as more permissive structures would tend to get everyone killed in short order.

Population growth moves us steadily away from the "old west / do whatever you want" scenario and towards the "submarine / co-operation is required to stave off disaster" scenario.

Decry it as creeping socialism (or whatever) all you want, but you're looking at a symptom, not the underlying problem.

[The ZipCar] will also still be there after you finish shopping.

That's a very good point -- but OTOH if you are worried about that, you also have the option of leaving your Car2Go car "locked" (and thus guaranteed to stay put) while you shop. You'll pay more if you do that, of course, but it's up to you to decide whether you prefer "cheaper" or "guaranteed available".

Then you're living in a daydream. There simply isn't enough land for things like big solar farms to create that scale. Or wind farms. And, for ENVIRONMENTAL reasons, Hydro in at least the US is nearly as developed as it's going to get.

The point is, non-renewables run out. That's why they are called non-renewable. That means we will be transitioning away from them at some point, whether we like it or not.

Whether we end up transitioning to solar, wind, fission, fusion, or just to shivering-in-the-dark in an open question, but we will be transitioning to something, because once the oil and coal has been burned, it won't be coming back.

What money is that? They already have sources of power as it is.

Residential power demand grows over time, as more houses are built, and/or people in existing houses start using more power.

When an area's peak power demand surpasses the capacity of the power company's existing power plants, the power company has to build more power plants; otherwise they risk brownouts or blackouts during peak usage periods (e.g. hot summer afternoons when everyone is running the A/C).

Building (and then maintaining) those additional power plants costs the power company money.

On the other hand, if the new houses (and/or some of the existing houses) add solar panels, that reduces the peak power demand, which means that additional peaking plants no longer have to be built, or maintained. That reduces the power company's future costs.

That's why it's not "charity" -- it's a win/win situation for both the consumer and the power company.
