> Do we know if there's a lot or a little lost electricity that is generated as a result of the main engines running?

That's not how it works. Car use an alternator instead of a generator because it lets them control how much electricity to make regardless of the speed at which the alternator spins. They basically vary the strength of the magnet in the alternator.

If they didn't the effect of "extra electricity" is a higher voltage, which would obviously be bad.

> I know cars waste a bunch of electricity (which is how hybrid batteries charge themselves when driving).

Hybrid batteries mostly save energy by capturing wasted energy when braking and when going downhill. Charging batteries from the engine makes the engine consume more gas.

What does 'increases the web experience' even mean? Using a phrase like that is clear evidence of confusion.

Hmmm, in another domain I'm familiar with, Cerberus Capital Management smushed together a number of firearms and ammo companies into the Freedom Group (https://en.wikipedia.org/wiki/Freedom_Group), and without to my knowledge screwing them up.

Why can't both be true. For some people, they're prone but overcome their instincts through nurturing and support from their environment to be different. For others, they're VERY prone, and lack nurturing and support from their environment to be different.

It's incredible to me how quickly we support, nurture, even worship people who are born into extremely good circumstances with all the advantages of the modern age, who are able to exercise common sense and ethical behavior (did they deserve it?), while others are blamed and despised when they were born into extremely poor circumstances, disadvantage after disadvantage (did they deserve it?)

> Drug users aren't victims of the war on drugs

Tell that to the world's largest prison population, half of whom are there on drug-related charges. A very small percentage of drug users are hopeless addicts who would consume public health resources in a de-criminalized, health-focused system, but all drug users are criminals under the War on Drugs and potential 'consumers' of the costs of law enforcement investigation, legal prosecution, and ongoing expensive incarceration.

> Drug users are victims of their own poor choices.

The majority of drug users aren't victims of anything - they're perfectly functional, productive, creative members of society, who you don't know exist all around you because they're completely normal in exactly the same way that the majority of people who drink alcohol are completely normal, functional, productive members of society.

I always like to give the Hurd its due. It is a great lesson in motivation, ego, and effectiveness.

Motivation, because it was solving a problem that didn't need to be solved by the people working on it. Specifically they had access to other UNIX systems but they "wanted" one which was open source. Linus on the other hand was a kid without access to such operating systems and he wanted to learn about them and play with them. His motivation was to simply build something he could play with.

Egos were another interesting part of the problem, at the time the great micro kernel / monolithic kernel debate was going strong. "Big brains" were arguing one side or the other and it was an area of research. So on Hurd, what had been thrust very much into the local spotlight, if it was going to be "big" then the people working on it wanted to be "right" and arguing over what was the right way to do it consumed an amazing amount of time and energy.

And finally effectiveness. By far the most effective thing to come out of the free software project is gcc (and by proxy the binary utilities binutils). These were tools that were built so that the "real project" could be built, and as such were just re-implementing an existing thing (C and C++ compiler) which was a little more than a senior undergraduate project in most universities. But gcc was useful because people could get operating systems when they bought hardware but the industry was really trying to make money by selling them the compiler tools.

So gcc/binutils came into the world with little ego (it wasn't changing the world, just re-implementing it). Was highly effective, and people were motivated to use it because it was an alternative to an expensive compiler suite. But Hurd, was no better, and significantly worse in that it was less developed than, the OS that came with the hardware that these folks bought (workstations) it was just that it had source and you probably didn't have source to the OS you were using (or you did but you couldn't share it).

Linux on the other hand, while still a toy was a better OS than MS-DOS in that it was already more 'unix like' than DOS was, and more useful than Minix because rather than just teach concepts Linus was using them to make the other parts of the OS as well. So the motivation was there to try it, Linus was not the egotistical "expert" who didn't listen to alternate ideas, and it was at least as effective an OS as MS-DOS if you didn't care too much about applications. As a result it was much more successful.

Don't make the decision based on taxes.

I had some options. They were in the money, and the price looked very sweet. But I had already sold enough that year to push me to the border of the next incremental tax bracket. It was mid-December, and I decided to wait.

But two days later, the company announced a deal to purchase another company, and the stock market didn't like it, so the price tanked. I missed the sweet price to avoid paying the taxes on those sweet gains. (That is, I avoided taking $X of income in order to avoid paying Y% of $X in taxes, assuming that the $X would still be there later. Don't assume that.)
Indeed. I don't understand why they do that (it was already like that before the brand change). It just scares away many potential users (people who have already used Linux, like open source etc.).

If you're using storyboards, another way of solving this is to let your segues set up the view models of the source and destination view controllers. You just need to create some segue subclasses for each source/destination combo you need.

Better than polluting prepareForSegue, and it totally decouples your UIViewControllers from each other. The coupling is in the segue, which is where it should be.

(1) The possible reactions can be meaningfully averaged, and the result can be interpreted as a reaction value as well.

So by “expectation”, I meant “expected value”, in the usual sense. If your objection is that “expectation” can't be used as this, I have evidence that suggests otherwise:

> what value does paying with your phone add over an Oyster

Phones and contactless payments actually do the fare-capping calculations slightly differently - if you do a "commute into London, then around London a bunch, then back" travel pattern, it can purchase a virtual central-London travelcard in the middle of the day, and adjust the commute-in payment retroactively. If you want that fare treatment with Oyster then you need to get the travelcard option loaded on it in advance.

Well, if I restrict my scope to the rich web client ("SPA") style work I have mostly been doing for a bit over a year, it is.

Anyway, you are usually right, but the project type matters: there might be just enough UI to enter some selection bounds and then kick off a batch process, or it might be a small game that is little more than a "busy box" consisting almost entirely of pretty artwork and responses. Plan & budget the design effort for the UI accordingly.

If you accept pure science as worthy of some % of the budget on it's own then it comes down to an efficiency argument. Creating some false color photos from various sensors is very cheap, adding yet another camera when we go to Jupiter regularly becomes kind of pointless.

PS: I for example think sending up astronauts is a pointless waste of resources better spent on other things which is a huge chunk of NASA's budget. I also support pure science even if I don't understand it. In wider context I think SS and the DoD should be significantly cut. Sure, I am a tiny minority but if I think 50% of the federal budget should go to pure science and I am happy to cut other programs that's part of the balancing act and well this ends up as ~1/30,000th the budget. Further, they did waste money sending a camera.
That is an argument whose logical conclusion is that NSA can't do any SIGINT using vulnerabilities: that the "equities process" result should simply be "always disclose". But that's not on the table in any proposal, including the VEP proposal.

I fear for Intel, AMD, and the US semiconductor industry. This is not competitive with Xeons yet, but it will be.
