Yes on the later question. In northern CA, they also offer "EV" plans where there are no more tiers. The base rate is higher (11cents/kWH after 11pm, peak of about 35cents/kWH during the day) than the tiered system (which starts at 5cents/kWH after 11pm with a peak of ~15cents/kWH, but grows exponentially).

But if you're charging an EV, you'll likely blow past the tiers anyway so having the EV plan works better. With a Model S, at least, you'll really only need to charge it at night and the software lets you schedule charging.

I think the criticism isn't so much that they're too responsive to consumers or not -- they obviously listen. The criticism is that there are so many holes to begin with and that their attempts to fix things that are obviously broken -- things that their competitors seem to be able to make work just fine -- often don't work or cause other problems. Knowing the Microsoft engineering culture, their stuff is mostly a patchwork of different groups not talking to each other. In the Windows API, there are something like 17 different representations of strings depending on which engineer/department wrote the code!

When you're disorganized like that in a giant company with a giant piece of software, it's easy to see how bugs can get out of hand.

People haven't stopped beta testing. Either in hardware or software. They have been quicker to release because the vast majority of software nowadays are done inside a sandbox (mobile apps, cloud servers, etc) rather than from scratch.

It's not like software or hardware back then was any more reliable. Office, OS9, Windows (all versions) have always been plagued with problems and one can argue they have fewer obvious bugs now than they did before - When's the last time you got a BSOD?

The counterbalance is that the consumer base is far far far larger now. Some of us who were at Intel at the height of the Pentium 4 were happy to have sold 40M units in a year. Mobile phone processors at qualcomm nowadays clear 400M/quarter.

If it seems like hardware and software bugs show up faster, it is because the userbase that uses and report such bugs (easy to do now via social media) is much much much larger.

Well, no. There are better compilers out there for ARM. Keil for one. More importantly though is the fact that real code that cares about performance won't just write a loop and let the compiler take care of it; they'll use optimized libraries (which both Intel and ARM provide).

Compiler features like auto-vectorization are neat and do improve spaghetti code performance somewhat but anyone really concerned with performance will take Intel's optimized libraries over them. So if we're going to compare performance that the end-user cares about, we'd use a benchmark that not only mimicked the functions we'd see in actual software but the libraries they use.

Exposure is exponential as well. So a camera with 2x exposure goes from 80% QE to 90% QE for example. The next 2x will get you to 95.

That may not seem like much but keep in mind that vision itself is logarithmic. So going from 98 to 99% QE gets you dramatically better results than, say 40% to 41%

Problem is, they've already spent the money both on internal equipment and people's salaries. Even if you liquidate the company, you're not very likely to get even half of that money back and you'll put thousands out of the job. Granted it's probably jobs they should've never had, but still, politically, it's rather impossible to do.

Aside from the problem of lobbyists, a big difference between DoD projects and private companies is that you have very few (hell, if any) private companies with enough cash reserves to do one of these projects. The private sector has very few "here's the money, now promise with sugar on top that you'll spend it wisely" type of contracts. Generally, you build something using your own cash (or venture capital/IPO funding) and then sell it. A ~$66 billion project is something even Apple can't fund out of pocket, let alone smaller manufacturing companies.

So we're left with the problem of how you can reign in costs if you have to give said contractor money just to start research. You can't be overzealous with auditing as that has negative effects on results; they'll be too busy keeping records and artificial metrics that they will spend less time doing the actual R&D. But on the other hand you can't just let engineers/managers run wild with an unlimited budget.

And at the end of it, if they're late, you can't just cut them off because that would mean you've thrown all the money you've given them away.

I doubt there's anything so sinister. One thing to note is that TSMC's 28nm process is ready now; chips will start mass production at the end of the year on it.

I don't think Samsung has their 32nm HKMG ready for the type of volume that Apple would need for A6. The A5 is already huge and would likely not fit in a phone. Apple's only chance of getting some more horsepower inside future iPhones without having to use the A4 again is to switch to a smaller process.

When all else fails, read the instructions.
