I think that was certainly a more interesting point compared to "who will do price discovery", which seems to be something that would likely find an equilibrium.

This article does mention it, but pretty briefly.

It'd be interesting to hear from people more familiar with the details of how all this works... perhaps there are some in the initial thread, but I haven't had time to skim it all: https://news.ycombinator.com/item?id=20877700

This. Cerebral people tend to denounce personality types as pseudoscience, astrology, Barnum effect etc. which they likely are.

But the usefulness of personality types is that they are shorthand for people who are into them to describe themselves without going through every story in their lives. It gives people a kind of crude vocabulary to convey their rough self image without using a lot of words and without the need for repeated exposure. It is kind of like an aggregate statistic that is wrong but still useful.

Oddly enough, that is extremely valuable guide to reading their behaviors. They may self identify as a ENFP or whatever while being something else, but even knowing what they perceive themselves to be is extremely useful especially in relationships. In romantic relationships it helps you navigate unknowns by anticipating them (trust but verify still applies but this gives you some Bayesian priors).

Just because a tool is not scientific doesn’t mean it’s not useful and to be summarily dismissed. (Note the subtle point: I’m not saying all non scientific tools are useful — just that some are) You just have to know how to extract the signal.

P.s. the big 5 personality test is more scientific and reproducible and reports along dimensions in percentiles. This is useful for research but no one ever mentions their big 5 scores in casual conversation. (I don’t even remember what my scores are)
As I read it, the word bubble in the Burry interview was really just used for clickbait purposes - his argument wasn't so much that index funds are overvalued, it was that there's opportunity in small caps because they're underrepresented in index funds, and everyone else is investing in index funds.
Thank you for your honesty ;)
It's odd that the presentation doesn't discuss alternatives to using silicon. Ultimately, this is akin to saying that there are limits on how small a vacuum tube we can make. We already know of a number of other potential computing platforms such as graphene, photonics, memristors, and so on. These things have already been discovered, and they have been shown to work in the lab. It's really just a matter of putting the effort into producing these technologies at scale.

Another interesting aspect of moving to a more efficient substrate would be that power requirements for the devices will also lower as per Koomey's law https://en.wikipedia.org/wiki/Koomey%27s_law

For all the talk about fusion energy research, much of the work done at the national ignition facility is related to the nuclear physics end of the "stockpile stewardship" problem. I have often heard that aside from obtaining the material, the design challenges are mostly associated with conventional chemical high explosives and directing the shockwave in a controlled way. On the other hand, there is no test ban on conventional high explosives so its surprising so few resources were allocated to that considering the billions put into replacing nuclear testing.

The index fund is holding the underlying stock, largely. The challenge is that if say 5% of their fund holders sell their shares in the fund, the fund has to sell the underlying stock to generate the cash to pay out. Most funds have a rule in their documents that if you are a large fundholder (holding 1% or more of the fund) and you sell, they can hand you stocks directly rather than selling them and giving you cash, but that doesn't work it it's tens of thousands of small fund holders selling.

There's an internet meme about "Imminent death of Moore's law predicted".

All Moore's law talks about is the density of transistors on a chip, and it's never been a linear progression of numbers. Recently I've seen news articles about some research into 5nm processes and other methods for increasing density of components on silicon, so it seems Moore's law (really Moore's rule of thumb or Moore's casual observation) isn't done yet.

Further, if there is a stampede for the exits, there still have to be buyers on the other side of the sellers. Those buyers will undoubtably include active managers along with those indexers with different time horizons and/or braver constitutions. Both will likely be rewarded for their patience.

The Most Demanding Job: Home Health Workers Are Crucial yet Struggle
The traffic in NYC is bad but I think there is more of a natural equilibrium that arises from the fact that if traffic gets bad enough, some portion of people will switch to the alternatives (public transport, biking, even walking), making traffic less terrible and equalizing everything. People don't really have that option in Los Angeles so it seems everyone is just stuck driving.
That is true -- most likely the preferences will go away, although who knows what they may negotiate.

The Field Guide to Human-Centered Design [pdf]
I'm not sure the "Environments" he cites are good examples for most types of software development.

Mathematica, MATLAB, Lisp, Smalltalk, are all development environments where there are a lot of questions around how to best deploy the software after you have written it. Maybe in some cases you have enough control over the customer environment where you can tell them "Just install MATLAB, then run this code we are giving you."

But what if the requirements are to deliver an iOS or Android app? What if you are building a web service? Or an embedded system? Or a game for a specific console?

Continuous integration and deployment are too very important problems that need to be carefully considered when deciding on or creating an Environment.

I think you have it wrong. Gravity and momentum are very well understood, but a double pendulum or three body problem is chaotic such that prediction past a certain point is useless.

So is the climate well behaved like the ideal gas law, or are there complicated sources of feedback like clouds, plant growth, and albedo which make it chaotic? There are quasi-periodic alternations between the fairly cold periods of the current ice age and the interstitial we're now in, so you should recognize it's substantially more complicated than just averaging the speeds of all the molecules.

I'm all for a cleaner better world, but I'll never believe someone who says they can usefully predict a chaotic system.

Yes it is. According to the source this particular public data dump consists only of entries with IDs linked a Facebook account.

How would they lose liquidity? Authorized participants [0] are always in the market for ETFs. If an ETF share price is crashing out of line with the index it tracks, they will step in and buy shares, swap them with the ETF issuer for the shares of the underlying stock in the index, and sell those shares for an arbitrage profit.

Even if one of the underlying stocks becomes illiquid, a big enough price divergence on all of the other liquid stocks would make it profitable to eat the loss or hold the illiquid ones (risky, but remember, there are many authorized participants competing with each other so if there is some way to make an easy arbitrage profit, they will find a way). You'd basically need the entire market to become illiquid.

Another thing that helps with anxiety is the psychiatry and psychotherapy combo. It helps with sleep as well, consequently.

If you haven’t tried it yet you stand a great chance of significant improvement, both from medication and therapy. The key to getting good help is a) convincing the doctor you need help and b) convincing yourself you need help.

The doctor part is simple - you need to demonstrate tangible effect on quality of life. Does your condition make you late or no-show for work? Avoid social situation? Something tangible, not just “I’m so anxious all the time”. It also helps to keep a sleep journal, it can used as evidence of QOL impact if you sleep 4 hours per night.

Convincing the patient who is not already convinced is near-impossible using standard rhetoric. The only thing I know to work is peer pressure - unearth three friends who already went through the therapy and the frightened mind of the sufferer might follow the herd. Which is why it’s important to talk about it.

> Most, if not all, companies do the bare minimum security they believe is necessary; anything beyond that is a waste of money and computing resources

This why we continue to have incidents and vulnerabilities which could have been prevented, or better mitigated. Most often these companies do not even know how to make a correct assessment of their risk. They move forward with this idea that it's a waste of money and resources, yet waste everyone's time with clean-up, or just go out of business as a result. Even with minimal security training and limited curiosity, this incident could have been avoided.
The dig at "Active Management" feels like it detracts from the article, but I guess they're playing a bit to the audience.

What I found a little more concerning is their glossing over of the liquidity risks. If everyone wants to sell an index, then at some point that index needs to liquidate shares (proportionally). Those shares won't have uniform demand, which is going to cause both price fluctuations (drops) which affect the value of the index. The fun part here too is that this can play some havoc with market-cap weighted indexes, which now need to adjust their holding %'s.
This was mentioned in the article

> Liquidity is not a huge problem for index funds. But, Ben, what if everyone rushes to the exits all at once? Index funds and ETFs are going to cause a massive crash!

> When an index fund investor sells, they’re technically selling their holdings in direct proportion to their weighting in the index. So there is literally no market impact.

A closed hearing from only a single party is not due process.

Then, the subject of the order must fight (at great expense) to regain their rights, which is a de facto presumption of guilt.

No hearing. No charges. No grand jury. No due process.

Due process might be a 30-day order to confiscate guns. If they can't get a grand jury indictment or involuntary commitment to a mental institution in those 30 days, the gun owner gets their guns back automatically and can't be subject to another red flag for 10 years.
Present day programs aren't optimized because they don't have to be. No one needs to gain a competitive advantage by squeezing the last bit of performance out of hardware because for a long time we've had steadily increasing performance levels and backward compatibility. Applications which need more performance than the present level of hardware can deliver so badly that they need to optimize to that level are very rare.

That's why Windows is the size it is nowadays... it's optimized for delivering the same user experience on all hardware, compatibility, language flexibility, manageability and user friendliness (don't laugh) instead of performance. It essentially performs the same function that Windows 3.1 did, but it does it on a far greater variety of hardware running a far larger assortment of software.

It's bigger and slower than it could be, but there are always trade-offs, and Microsoft hasn't really had any competition in operating systems for decades... Linux and variants have their place, but it's not on the desktop for most people, at least at the moment.

If your strike price is near 0 then you should have done early exercise with 83b election to avoid the AMT tax (if your company permits this of course).
I think people undersell the value of safety. Back in the 80's and 90's, it wasn't uncommon to drop into assembly to grab every last cycle of performance, since computers were so slow. We also didn't do garbage collection, and people were writing in languages like C and C++. Software from then was also prone to random crashes and freezes, which doesn't happen so much anymore.

We've started to come around with languages like Rust, but a lot of engineers have (in my opinion rightly) come to the conclusion that it's better to abuse the faster speed of computers to have a higher assurance of the software being correct. Could I conceivably get better performance if I wrote something in C and wrote a custom allocator? Maybe, but I'd probably make a mistake, and my GC'd language is fast enough for most of what I do.
Facebook has 10+ years of data about people and their friendships and relationships unfolding through time (tagged pictures, relationship status, updates, likes, etc.). It's hard to tell if they've built and deployed such a model for proposing matches, but this could be their killer feature. Superficially, this product seems no different from existing data apps.
> This is not true if, like most stock options, yours are ISOs and you don't hit AMT.

I think for most folks in tech not hitting AMT with any reasonably sized option grant worth buying will be extremely rare:

1. Options vest, usually over a 4 year span, so if one, two, three years go by at your startup and there isn't a large difference between your strike price and the current valuation, well then that's a huge signal you don't want to buy in any case.
2. Given your average software developer salary and average range of options, it takes very little to actually hit AMT.

IWG is tiny (a mere $3b in revenue; $4b-$5b market cap), they'd never land all of WeWork's customer base or WeWork itself. They'd trivially be outbid. SoftBank would acquire WeWork and continue operations before they'd let the business go to a small company like IWG or watch WeWork get acquired for ~$500m-$1b (which is all someone like IWG could afford).

Far larger players like SoftBank, Blackstone or KKR would be all over scooping up the bones of WeWork. There's certainly no scenario where WeWork doesn't end up in the belly of a private equity company, or a large real-estate holding company. The next recession will destroy them. They'll be lucky if they survive even outside of a recessionary environment.

In many countries people carry more than one phone/SIM card. Mostly for separation of concerns, i.e business and pleasure.

Yes, and "environment" issues can certainly become fixations for some people. For example, VMs. It all comes down to the reason a person holds a certain view and how broadly that view is supported in their own specific programming sub-community.

Differential privacy is a tool for doing many useful computations in ways that provide value to end users beyond advertising. Apple uses it too. It's like saying "wide acceptance of end to end encryption legitimizes it for Google". Do you want your phone to give you real time traffic jam information without giving away your position? Do you want to better recognize and classify photos with ML while keeping your photos private? That's differential privacy.

The rest, an implication of a desire for Google to fail even if the entire business model were based around privacy preserving techniques, makes the privacy saber rattling seem disingenuous and a means to a different end.
It's not an unusual tendency for women to prefer men older than them, and men to prefer women younger than them. So these preferences can match up to a mutually preferable arrangement for both parties.

> where some crappy code stuck and is in use 14 years later

I think this boils down to a roll of the dice. Its possible that some code is simple enough, or some engineer is smart enough, that tests are not really needed, but given the choice to not unit test would be made early, and its very hard to know the complexity of the solution at the beginning, you're really just rolling the dice with regards to whether it would work out. Sometimes you get a huge payout by delivering good code fast, but sometimes it can really blow up in your face with lots of prod errors.

Personally, I'd rather smooth out that large payout vs large explosion curve by just writing tests. If we could have pushed out the code faster, that is a loss, but if the code would have had many errors, thats a gain. So probability distribution with regards to payoffs is smoothed out.
I guess the risk is that if people withdrew funds in a recession/crisis, they would blanket-kill every company out there, even companies doing really well.

No they don't. Let's suppose we have A Corp and B Corp both 50٪ of the total market and A Corps price and hence market cap falls by 50٪, making it 33٪ of the total market. The holdings of a fund haven't changed but the exposure still equals the market.
