Very likely. Especially since it seems that Prius battery packs are holding up even better than expected, I'd expect the same from the Tesla packs (unless they use a different type of battery), and buying an older one for a low price seems like a good idea if you need the storage.

Unfortunately my roof is pretty unhelpful as regards solar panel placement. I have a large flat roof in the shade. Otherwise I'd have already installed solar panels.

I agree with you and I'm not at all saying they were treated well. But if the Chinese government wanted to be unsubtle, they'd be beaten up and jailed without further discussion. Apart from that: the cases at Mt. Gox and the other thieves... sorry, money changers, show that regulation is going to be needed pronto. The Chinese version of regulation, however, is to ban it.

What they do, as I gather from the article, is that they drill holes in specific patterns around installations. The pattern then absorbs seismic waves and turns them into sound and heat at the focal points of the waves. No idea how much heat or sound, but in general it's an improvement over having the building destroyed.

Governments do have a role in money systems. The Dutch Central Bank is celebrating its 200th anniversary this year, and it's interesting to note that the first 30 years were spent trying to establish faith in paper money. Once this had happened it opened the way for some much needed liquidity in the economy and a lot more economic activity happened as a result of that.

In the 11th century the Vikings raided the monasteries. This provided a much-needed economic boost once the gold came into circulation again. With paper money you NEVER have an end to circulation: you can always print more as needed. So it is very useful if you want to have some influence over the economy to have a currency that you can control. And this has very little to do with "governments being evuhl" and a lot with governments being the "management board of capitalism".

Crises, finally, are not caused by misallocation of funds, but by a lack of return on investment in every sector. *This* causes misallocation of funds as capitalists (sorry: investors) then become desperate for ROI and start to invest in tulips, bad loans and Zynga shares. Eventually that collapses, leaving everyone with worthless stuff, companies go bankrupt and the system is rationalized once again. ROI is restored by companies that are able to buy out their competitors for an apple and an egg, and things start anew.

I do have disagreements with the author - money and contracts are not the same, for instance, and while the choice of distribution of money is political most countries have a central bank that does this, usually outside direct political control - invalidating at least part of the thesis as I see it. But I doubt its complete nonsense.

Buying stocks or even the products of a company that supports Greenies is not a responsible act.

And buying the stocks of a company that ignores the law is somehow more responsible? Basically they were asking Tim Cook to ignore the federal mandates on green energy.

Even apart from that moronic idea, locally the number of datacenters we can actually place here in the country is now limited by the capacity of the grid. Doing small scale experiments on how to diminish that reliance, or even go off-grid on a large scale, is very likely to be a smart move. And that is not even taking into account the fact that in the country next door they are actually paying companies to use energy on days they have too much free energy (wind and solar). It makes the energy-intensive companies so competitive that a big one in this country has just gone bankrupt. Making sure that Apple retains an ability to mix and match between different energy providers is just sensible business, however you look at it.

Two points here I think:
1) Yes it is possible to build maintainable triggers - I'm doing it right now, as a matter of fact. However, it's certainly not my first choice since it's (a) hard to debug when they cascade and b) performance is hard to keep under control as they proliferate. Just look at Oracle's older products (or heck, look at Apex) and the huge amounts of triggers firing for even the most simple of tasks. It's a weed that you have to control rigourously or it will grow out and suffocate your software. It is NOT a best practice to use triggers if you can avoid them, they're a last resort if all other options are off the table.

2) Centralizing the business rules has a lot of repercussions beyond the technical side of things. Look at BeInformed's products for that. With proper definition of business rules, a good business rule engine can generate most CRUD-code from scratch, dynamically populating the screens with the required fields. BeInformed's latest product even generated the workflow at runtime, all business rule based. It was much more advanced than reactive. Unfortunately they invested too much and they're now up for grabs as they went under. As I understand it, SAP and Microsoft are fighting over the remains. Which is a much better buy than Reactive.

I'm sure you can find an edge case where some platform can't access the centralized business rule repository, or needs an exception. Or it becomes inflexible and unwieldy. Those are generally signs of failing organizational processes, not technical issues.

That said, there's another point: why can't databases integrate with business rule engines? We're still stuck with constraints from the 60's, even Domain-Key constraints have to be programmed instead of declared. Databases could leap forward if they would deal properly with time, versioning, and business rules. Instead, we get slightly higher marks on the TP benchmarks. That's useless.

It was actually the Dutch intelligence service that handed over the telephone data of 1.8 million phone calls to the NSA. The responsible minister barely survived in parliament last week. As it turns out, none of the leaders in the EU advocate spying on their own citizens... but handing over all the data to another service and getting back the interesting tidbits, now that's different. While they decry the NSA in public, in private most intelligence services have similar programs running.

There are a lot of reasons why the USA was the "good guys" in the Cold War as far as the EU was concerned - but I think that if you were to ask around in South America there won't be a lot of people thinking back fondly on the good old days, what with the US laying mines in civil harbours, the CIA openly sponsoring coups right, left and center, and all. In the EU the USA had to win the propaganda war versus the Warsaw pact. You don't do that by openly showing your skull-and-bones flag. Apart from that, a lot of people sincerely believed they were the good guys and acted like it. I think that the Snowden files have damaged that image beyond repair.
