> Should the need arise for Craig and Mark to return the stock they borrowed (someone calls in their shorts), they will probably need to pay a lot to convince the people who own the actual stock to sell to them, especially if the owners are aware of the macro situation.

In your scenario there are only 100 shares available! If Craig and Mark get margin called, how are Sally and Bob each going to end up with 100 shares?

I've always wondered why most people are not passionately opinionated about methods for heart surgery, and yet are highly opinionated about economics (for example). The latter seems more complicated, in many ways, and yet people have no problem having an opinion about it. Why do you think that is?
I'm not a developer, but the process is the same for them.

Where revenue is directly attributable to something, that's taken into account. For non-technical roles, business decision-making ability is heavily accounted-for, as are skills like legal research that are fairly specific (that's one of mine). It's not a very precise process, but I have yet to see any precise process for compensation that wasn't obviously pretty bad. There's also a requirement around capital contribution in relation to your pay level, and then you also get some quarterly/yearly distributions.

Our entire company is remote, so comparing to market rates is tricky. It's below-market for the Bay Area (but so are most startups), and far above market rates for the area I live in. Anecdotally, my pay (and responsibility) has gone up significantly here compared to previous jobs because this system allows a pretty dynamic evaluation base, whereas my previous employers' compensation systems didn't know how to account for outliers in output and competency, at least below executive levels.

1) Dear god, people actually do all that JavaScript stuff at the top?

2) "CSS is a declarative subset of JavaScript, optimized for styling tasks." This is so incorrect it's irresponsible.

3) I'm genuinely confused by how he speaks as if CSS is some new revelation. "are you willing to embrace the change, or are you married to an inferior methodology?" What? Both languages originated in parallel in the mid-90s for totally different purposes. Only in recent years has it become popular to do styles in JavaScript, not the other way around.

For those who are new to this space: do not listen to what this guy says. He is at best extremely misguided, and in some places factually wrong.

> The older the building, the more maintenance will be required

Yes, in the current model. But the same is often true for most things (cars, computers, etc.). I wonder though if a different setup is possible, the one that optimizes for low maintenance and modular diagnostics and replacement. If so what a price tag would be. If it is well into 6 digits what scale would be needed to drive down the price extra to 100k or less?

Maybe that is not feasible, but I think we are at the state where if this were possible enough folks would jump at it.
> Everyone seems to suggest that the fix for high housing prices is to simply build more densely (more supply, same demand, therefore prices should go down right?). Yet that appears to not be the case either - as buildings get taller and more dense, costs seem to increase outside the direct supply/demand system [2] and those units which are built are typically more expensive then low density options.

The issue is that density attracts people when it's scarce, because people like it. You can walk to shops etc. So if you build a little bit of density, people want to live there and the price goes up.

What you need is to build a lot of density, so that the supply satisfies the whole demand and it actually gets the price down.
It's all over. Memphis to Miami, New York to Nevada, San Francisco to Syracuse.

The historical ratio of house price to income that was considered affordable was about 2.6. If you earn $100k, you should spend $260k at most on your house under this rule.

Nowadays very few metros have median house prices at a level where the median household income would qualify, using that 2.6 ratio. Almost all of the cities with cost levels at that ratio or better are Rust Belt cities, and even many of them are right at the threshold.

Check out the full list: https://www.citylab.com/equity/2018/05/where-the-house-price...

Obviously interest rates, tax policy, etc. can change the monthly expense equation, so what may have been too expensive in the past might be more affordable now with lower interest rates.

However, even with a reduced cost to finance, there are still hefty down payments that need to be saved up for which are cost prohibitive. And higher property values need to pay higher property taxes. Maybe even "mansion" taxes in a few places.

Wow that link to GeekDad is absolutely toxic. When you visit, it shows a banner that begs for you to turn off your ad blocker promising that they don't have malicious or distracting ads... then in the fine print below that, it says "okay I know we currently have a lot of malicious ads, but that's out of our control, we promise!"

Seriously, that's why people use ad blockers. If you're running content on your site that you have no control over, stop doing that. If you're serving malicious ads, at the very least turn off the banner that tells people you're not serving malicious ads.

If we want affordable housing, housing costs must necessarily fall behind inflation, which is the thing brown lawn regulations are trying to prevent.

I'm not saying brown lawns are the way to lower housing prices, but the whole point rests on the value judgement that expensive housing is better.

>I didn't invest in SolarCity, and don't know the specifics of what made it a bad company.

My evidence is that it had to be bailed out by Tesla, then wound down. They spent vast amounts of money to grow; you know the old selling a dollar for $0.80. Borrowing short, lending long. Most of the time, that doesn't work. Solar power is a commodity, and prices are rapidly falling. I think the onus is on others to prove that it was a good business that couldn't handle short-sellers.

Again, if it was so simple to destroy a company through shorting, why isn't it happening everywhere, all the time?

Furthermore, who is "they"?:

>They are not shorting because they think Tesla will go bankrupt. They are shorting during specific periods when Tesla is most vulnerable, and covering when they fail to achieve their targeted goal. They are shorting to bankrupt Tesla.

I've been short TSLA twice (but net long through ETFs). The first time was early, and I lost money. The second time was in the recent run up after the 5k/week news, when I made a few bucks.

Was I trying to bankrupt Tesla?
I agree with you. The tradeoff for me hasn't been "private office" vs "remote work", it's been "face time with colleagues/friends" vs "remote work". But, as you say, remote offices and the various other positions in that gradient are very exciting.
You are basically saying that people should be couped up in tiny little shoeboxes, so that parks can be larger. I don't mind bigger parks, but it's very nice to have a big yard and a garage too. With a city like approach in the suburbs, you will have less personal space. I am not talking extreme here - regular American properties in most middle class areas work just fine in my opinion, and they are usually not overly large.

> For the land of the free, some US rules are a shock to me.

The emphasis on freedom in the US, like many things around the world (like religion), is mostly a result of the conditions then the other way around. What would you do if you find yourself in a disorganized country of inequality and insecurity? You build the most available home construction of the most available material on the most available land. So if the economy crashes, you get sick with poor coverage or the government goes haywire you can still, in theory, live a decent life. It doesn't have that much to do with "everyone do whatever they want".

Effective code tends to put a lot of functionality behind a relatively small interface, and tends to work for a long time without needing attention.

A "change detector" is exactly what you want in this situation. Does the code still fulfill the spec (tests)?

Tests that feel like they need to be changed every time the code changes are generally white box instead of black box, or the interface to the code being tested is too large.

Nice comment, echoes a lot of my feelings about ML. I have a question. You write

> (2) Okay, when simple regression doesn't fit very well, we keep trying? Okay. Say, we try logistic regression, ridge regression, L1 or L2 regularization regression, regression trees, boosting, ..., neural networks, etc. Uh, which is better, L1 regularization or L2 regularization? Uh, this sounds like throwing stuff against the wall until something appears to stick. Sure, that can work at times, but are we really satisfied with that? Wouldn't we want some more solid reasons for the tool we pick? Lots of places elsewhere in applied math, applied probability, and applied statistics we do have solid reasons.

I'm wondering what these "solid reasons" could be? Some sort of experience based on past data? An example would be helpful.

> I think NoSql, especially things like Mongo, got popular because it is super easy to program with javascript.

NoSQL caught on because of what it doesn't do: attempt to implement the relational model.

A lot of people were using MySQL in infamous LAMP stacks to set up websites with virtually no business logic.

So you had:

1. An application that didn't need the relational model
2. A DBMS that had a very poor implementation of SQL, which itself is a poor implementation of the relational model
3. A large community who didn't know anything about database theory.

When you're using MySQL as a glorified hashtable, you get none of the benefits of the relational model, and all the downsides.

From their understanding of the technology, throwing all that out made a lot of sense. It's pretty reasonable to use a distributed hashtable if what you want is a distributed hashtable.

I think the backlash now is that NoSQL marketed themselves as a capable alternative to SQL DBMSs. But they had no query optimizer, no transaction support, no reliable backups, and no schemas. The last was supposedly a selling point, but the reality is that your data always has a schema, and code will crash if the data doesn't match it.

Great marketing, but people were sold half a car and then told building the rest themselves was a feature.

> One of the problems of many stacks is that the frameworks wrap general purpose languages over SQL, which, is not really a good idea, SQL is a vastly more capable language for dealing with relational data and layers built over the top often dumb down the database.

Another problem is that object-orientation is fairly broken, and ORMs tried to figure out how to shoehorn relational databases into inheritance hierarchies. If current notions like value classes had been around, a more straightforward mapping would have been possible.
The price will rise until Bob or Sally is willing to sell their shares, meaning they don't end up with shares; they end up with cash.

There exists a price for which Sally or Bob are willing to sell their shares. If Craig needs to offer $100K per share, Bob or Sally is likely to take it.
I concur, its difficult to get funding for this type of research without having a tangible way to benefit your potential benefactors.

From personal experience, I've had to work on numerous applications that I didn't really care for but provided me with the funding to actually pursue my research.

On another note, the subject matter Ewin & Professor Aaronson are talking about is pretty complex even for the average CompSci person; I'd wager if there was no mention of a corporate entity or real-world example this article would be met with so many questions about its applications to those same real-world problems.

Rant concluded :P
You have it backwards, increased density results in higher prices.

However, there are multiple cycles going on. If you build a development you end up with a lot of people of similar means all buying homes. But, over time things change as people get fired / retire / inherent homes etc you revert to the mean over time. On top of that as homes age and become less desirable you get massive downward pressure on property values over time.

In the other direction you have artificial scarcity and sometimes increasing population propping up home values.
Thank you very much for bringing this to my attention!

Well yes that's how stocks work: the firm is not involved directly when they change hands. (Although you have it backwards here: the sovereign fund is buying so the money leaves its "pocket".) However, a firm like Tesla (and really, most corporations are like this) is still dependent on capital markets. They might want to issue stock in future, and they definitely need a steady stream of short- and medium-term loans to keep operating. A lowered stock price makes that more difficult. Short selling is still perfectly legal, but it does seem a bit sketchier if the tycoon is selling short not to make money from that investment but to protect other investments...
Agreed.

Where do the people go? You don't want to sprawl (build on every square meter on the planet) and you don't want to build dense housing, so what is the 3rd way?

Just "sorry, you didn't get in line for a house fast enough, just go be homeless now?"

Businesses need to employ people. The people employed by these businesses need to live somewhere close enough to the job that they can work there. Because of this, you need to build more houses near the jobs, or move the jobs (which creates its own set of social problems).

The problem is that there will always be a conflict between the people who already live in an area and want their homes to increase/maintain value, and people who need homes available to them which will devalue the homes due to there now being less demand. The needs of both groups need to be met as best as possible without steamrolling the other, but everyone needs to be willing to compromise.
