That is one of the xkcd comics that really bugs me. Yes, if you treat every character as an independent element and try to calculate it's complexity, those passwords look really complex. Unfortunately, most password crackers aren't brute force crackers that try every character combination. They try combinations of well known words, phrases, and number/symbol combinations. So, you're mathematically complex password is exactly what crackers are looking for.

To be fair, as long as you're the only one in your company doing it, it's reasonably secure, as soon as it becomes company policy, all your passwords fall within regular cracking procedures, and are likely easier to crack.

That's because they need to stop trying to make a Netflix clone and do something new. Apple pay isn't better or all that different from Google's NFC pay, the difference is that they've done the legwork to build a network of vendors. Similarly, whoever can build a model where their service has live streams of TV shows and channels that people want, or something similar, will be fantastically successful. It's not clear, but this may very well do that.

No, it's about encouraging the correct behaviors, not the correct results. Most people fail several times while studying/practicing STEM subjects (or most subjects worth studying, for that matter). If we insist on telling little Johnny how gosh darned smart he is all the time, he may not be any good at handling that failure. Or he may assume that "he isn't a math person" because he's always been told how smart he is, and he just isn't getting it. Instead, we ought to be encouraging him to try harder, fail better, and reward him for persistence, and good study habits.

Society rewards results. Definitely. So getting excellent results is important. But, parents and teachers aren't necessarily there to evaluate results. They're there to teach Johnny how to get them. Rewarding hard work, and continued effort is one important way to get those results, and it hasn't been focused on. Instead, we tell him that it's alright that he didn't get the right answer, and he should stop trying so hard and come have a cookie so he doesn't lower his self-esteem. This has the opposite effect, he doesn't get the results, and he fails to learn about work ethic.

Ah, the classic, "I don't like the peers, so now we get to fall back to no data whatsoever and argue from gut feelings" gambit. Good one gweihir, good one. Fortunately, that's not how science works, or we'd all be screwed. "Your peer group way over-represents geologists, and is therefore skewed toward round-earthism, therefore we can now discuss my ideas of flat-earthism as equal and valid."

They can bask in their pure capitalist sunshine as soon as they buy right of way access for every mile of line they use, instead of leveraging the government sponsored right of way access they've been given. They can also pay a requisite sum for the monopoly access they were granted. Then they can setup any internet they want. Until then, they need to deal with regulations.

The device was great, but no one really buys a Kindle for the device. They buy it for convenience and content. The Sony ebook store had a terrible selection. Worse, you had to buy it on the computer and transfer it to your device. Nirvana is achieved when you can pick up your ereader, decide you want a book, and can complete the selection and sale immediately. That's why Amazon was willing to eat the cost of the cell subscriptions, because it meant people could complete a purchase when they wanted, not when it was logistically feasible. That's become easier now with more ubiquitous wifi, but Amazon won on content and ease of availability.

I still own a PRS-505 and it's a wonderful device, especially paired with Calibre, but it's used almost exclusively to lend to people while I used my Kindle Paperwhite.
