It's nice to know that the other people watching a show are also at the same point as you are (or relatively close), allowing you to speculate on what might happen next in the time between episodes.

I also like looking forward to the next episode, which doesn't really happen when you can watch that next episode immediately (and self imposed waiting doesn't feel the same).

"They will take HBO linear and call it HBO Linear,” he said. “That is HBO if you really want to watch it on somebody else’s schedule.”

Am I the only one who likes shows being made available once a week, rather than all at once?

This is a no tuition guarantee, not a no parental contribution guarantee. In effect they are saying that if you make under 125,000, you'll only pay 20-25k for living expenses (room/board/textbooks/etc), which is similar to Harvard and Princeton, considering they both try to structure aid so families do not have to take loans out to pay them. Coincidentally (or not), this is also equivalent to the FAFSA EFC as you mentioned.

In this announcement Stanford clearly says that the no parental contribution level is 65,000, raised from 60,000 and now equivalent to Harvard/Princeton.

It's just not. It's not easier than swiping a magnetic strip and signing something, or typing in sixteen digits (or using autofill or the site's previously saved CC info) and pressing buy.

It's much easier to take your phone, open an app, and scan a QR code, than to take out your credit card, transcribe a 16 digit number, check the expiration date, and enter the CSC (or is it CVC?).

Sure, for websites where your information is already saved, or if you leave all your credit card information saved in the browser, then this isn't easier, but they're still pretty comparable in my opinion. Even if it was slightly more work (which I personally disagree with), I would find that worth not having my credit card information saved by who knows how many third parties.

It's not good that I can't demand a return or have recourse in the event of fraud.

I've never had to go to my credit card company for a refund, since most places I buy from will take refunds with a receipt or proof of purchase (and if they don't, why would I buy from them?). Fraudulent purchases are another issue, but the risk of fraud is lower with bitcoin versus credit cards (no single number that allows access to all funds, a properly secured wallet is impossible to steal, although I know wallet security is still not the easiest thing to have).

And it's not a benefit that with bitcoin I have to spend the money first (to buy bitcoin) and wonder if it will hold its value, versus just buying stuff when I feel like it on credit and covering the transaction within 30 days at no interest cost.

This is a very real problem, and what I think will truly determine whether bitcoin gains anything near a large following.

I believe there are proposals to allow pruning the blockchain, but I'm not 100% sure on the details.

To guarantee a transaction goes through you have to wait for it to be confirmed, but most transactions really aren't that important/high risk, so beyond checking that the address does actually have the money, it's instantaneous. Many payment processors (I know Bitpay has this option) actually take the 0 confirmation transaction risk, allowing customers to pay instantly.

Transaction fees are not high, with a typical fee of .0001 bitcoin (3 cents), which is small compared to credit card fees. While work needs to be done converting to/from cash, actually using bitcoin (that you already have) to buy things is a better experience than using credit cards. You simply grab your phone, scan the QR code, and hit send. This is much better than entering your credit card for the thousandth time on another website, or being redirected to paypal, entering your password, and choosing your preferred payment option for the thousandth time (stop asking me to use Paypal Credit!).

Using an Android wallet such as Mycelium, or a desktop wallet like Electrum doesn't require you to download the entire blockchain, and although that comes at the cost of some trust, I personally don't find that problematic.

Basically, bitcoin has some problems, but I think some of your criticisms are no longer applicable to most everyday usage of it.

Stripe: Bitcoin 11 years ago

Coinbase is free for the first million dollars in transactions. Bitpay is free IIRC.

I'd agree with the broader point that this guy is making, he's being exploited by the university, and doesn't owe the school any additional work.

That being said, he does owe his students the chance to at least look at the culmination of their semester's work. I know at my university, professors are obligated to have exams available for at least a year past the date they were taken! Maybe if allowing students to look at their exams would truly take an additional 75 hours of his time as claimed, he'd have a stronger case, but that's simply not true. If the student was requesting him to explain why a problem was wrong, or engage with this exam in anyway, I'd be completely in agreement. Hell, he could just put them all in a box outside his door, or maybe leave them with the departmental secretary (this happens all the time), or come up with some sort of solution.

His broader point still stands, but this is absolutely part of the responsibilities of a teacher, and I can't get behind this guy making a point at the expense of his students.

From the email it seems the student just wants to see his exam, hardly an unreasonable request. He doesn't ask for a "review," of the exam, and this seems like it should take all of two seconds. He walks in, takes the exam, and leaves. If the exam can't leave your room, he walks in during office hours, looks at the exam, and returns it. I've caught multiple grading errors simply by actually collecting past exams, and would be understandably pissed off if I was given no opportunity to collect an exam I'd taken.

While the contract teaching situation seems pretty bad, this guy seems unreasonable here.

Technically it'd be fine, there wouldn't be any direct evidence... but using a VPN on campus at the same time a bomb threat comes in through Tor could be enough to draw some suspicion. For something like this though I don't think they'd dig that deep.

Cinemark was sued in the wake of the Aurora shooting, and their defense has been there was no way for them to expect something like that to happen. In this case, the threats they've received would prevent that defense, and the theaters don't want to take on that liability.

I think it's been around for a while, but has been updated/revamped significantly since the last time I saw it.

Am I the only one who doesn't really have a problem with this? A store increasing prices and not offering pre-orders does not seem like much of a problem. Increasing shipping times is a little more questionable, but assuming they aren't slowing already ordered books' shipping times, then again, what's the problem?

Those two categories have some overlap though. I had an account on quora, and for browsing the site the requirement is fine, but when searching for something and stumbling on to content from quora (especially on a mobile device where typing is a chore), the added frustration was enough to make me delete my account.

The call unsettles him. “I will do anything to ensure that I never have to hear that woman crying ever again,” he tells me later. I get the feeling that, in Mike’s mind, other people’s emotions show up as noise: data that has no apparent purpose, and that his internal software cannot process.

I found this a very unfair judgement made by the author. Giving Mike the benefit of the doubt, I get the sense that he cares about her, and wants to stop the root cause of her suffering, not that her crying made him uncomfortable because he "cannot process" it. The author seems to be trying to play up the rational side of Mike and his engineer's mind at the expense of his emotions.
