Turning Red was surely a hit on Disney+. Hard to see from the consumer side what the impact was, but disney+ is a money machine and the can easily double the price.
COVID 19 also spread almost entirely through airflow.
I think we have an airflow problem in our hospitals (and other public places)
Luckily, that's quite cheap to fix. HEPA filtration is sufficient for both problems (no need to bring outdoor air in).
We should probably be:
* Mandating that all hospitals filter all air every 10 minutes. That could be simply a matter of buying bedside standalone air filters for every bed. They aren't medical devices, so will probably cost <$20 per bed, available from Amazon tomorrow.
* Start a study of air refreshes per hour Vs infection rate for various airborne pathogens. These studies typically can't be done for ethics reasons today - it wouldn't meet ethics standards to deliberately infect someone with something harmful. However this is happening hundreds of millions of times per year already, so I think it is in everyone's best interests to do the science to understand it so we can prevent disease spread.
My curriculum was: Year 1: Intro Comp Sci / Year 2: 2 courses in Logic, 2 courses in data structures and algorithms / Year 3: 2 courses in processor design, 1 course in finite state automata, 1 course in parsers / Year 4: a course in ethics, a course in team programming (which covered UML and version control), and two electives.
I believe a major was 14 courses so I'm missing one, or it may have been it was three electives. I didn't take databases because I was already a paid sysadmin before I started college and mostly at the time database courses were just ten tedious weeks of normalization crap.
Also, treat your interns better. The reason to hire interns is because you plan to devote some of your resources to help them in their professional development. Stop asking what you can get out of your interns and start asking how you can best give something to them.
He's far from perfect, but what he's accomplished in the US as a kid from Austria . . . absolutely amazing. Over and over.
If the US Constitution didn't prevent it, he'd surely be President. (And I'm from his political antipode.)
His life story is really inspirational, but his terms as governor sort of exposed he didn't have a great aptitude for elected politics. After he got whooped in his 2nd year midterm on the bond issues, he acknowledged that to be an effective governor he needed to get better at working with the legislature and making the case for his priorities. Then he served another six years with no major accomplishments; he never really felt like he was in the driver's seat after that midterm. He remained personally likeable, and it's true that Democrats put up only a token challenge to his second term election, but this maybe emphasizes the point: he was not in control of the issue agenda in the state, he wasn't a real threat. He didn't do a terrible job as governor, but he did do a very passive job. And in his second term when he did try to engage with the legislature, it didn't work, and mostly (as the article notes) his popularity eroded significantly. After leaving politics, he didn't really stay engaged in the party or build connections in the state, and indeed it's telling that Republicans have had a terrible record in California since.
He's never sought any federal office, and I have no idea why the article accepts the false premise that after being Governor, the only other option is to run for President. He could have, of course, ran as a Senator (Governors often do this!), ran for the house (Governors occasionally do this!), gotten involved in executive politics by taking any of a number of federal appointments that could have been open for him (or made a case for a cabinet position). He didn't. The article suggests he wouldn't mind being Secretary of State. If that were true, we'd expect him to have done... uh... literally anything connected to diplomacy in the 15 years since he left elected office?
And frankly a lot of his public engagement with politics over the last few years has been pretty surface level. He's talking directly to the public, mostly in (yes, well articulated) platitudes. I agree with him on all these issues and I'm glad he's using his bully pulpit to advocate for good things that I agree with. But mostly that's where the engagement stops. He's not day-to-day running civil society organizations, he's not building connections with politicians, he's just sort of weighing in in the same way a lot of people do on issues he cares about.
I do think there's a lot to admire in Arnold (his life story is amazing). and I don't have any hostility towards him. He's funny, he's using his platform for good, he's a sports hero, he's a unique and fun actor. I don't think he's great at doing electoral politics.
When you short a stock, you are basically selling a stock you don't have. Thus you get money and owe someone else a stock (in practice what happens is someone else unknowingly gives you a stock for free and then you sell it, and they get an IOU for a share of the stock later; but let's not worry too much about the mechanics). Once you have this IOU, you can hold on. The value of the liability associated with the IOU can go up or down. If it goes down, then when you discharge that liability by buying the share you owe, you will pay less than you were paid for the short, thus making a profit. If it goes up, then you will pay more and thus lose money. One risk with a short is that your liability is unbounded. In a traditional stock purchase, the worst that can happen is that you lose the money you put in. In a short sale, you can lose many multiples of the money you put in if the stock does very well. Under a few circumstances, the IOU can be called, forcing you to prove that you have the money to buy a share; for instance, if you were to short $1,000,000 in shares and the share price triples, you owe $3,000,000.
To summarize: when you buy a stock, it's because you think it will be worth more later (again, let's set aside dividends and other things). When you short a stock, it's because you think it will be worth less later.
The reason shorting is permitted is because in general, there is a belief (mistaken or not), that additional liquidity -- more trading -- benefits everyone involved in a market by reducing the spread between prices for buying and selling; additionally, shorting makes it possible to hedge your exposure to a sector (i.e. to trade off some upside in a sector with some corresponding downside and vice versa).
