Speaking as someone who has had to write performance critical data structures and also someone who does well with whiteboard interviews - there is a large difference between writing an algorithm with the advantage of having time to read, reason, and test your code and doing it on a whiteboard. There are many people who would do a fine job as a filesystem developer but might not be able to pass the interview for it.

The current situation benefits me personally in many ways, but I recognize that it's unfair to many other people.

Which is completely useless except for jvm developers.

The performance of the compiler itself matters, not just the performance of the generated code, because, since it's a JIT, compiler code continues to run.

Oh my, I’m that guy today.

Whoever said it, I have a super hard time believing DHH couldn’t implement bubble sort on a whiteboard.

Am I the only one? I get that people hate whiteboard/algorithm interviews, but bubble sort?

for i = 0..n:
for j = i..n:
if arr[i] > arr[j]:
arr[j], arr[i] = arr[i], arr[j]

Everyone in this field should be able to do this, maybe not right away, maybe not without bugs, but with help within 45 minutes.
Why not!? If our next president will just wipe out student debt--without ending government backed loans--why not charge $1MM/year?
That is on top of the Federal tax rate. Americans pay into two separate tax systems. It would be like paying taxes to the EU in addition to your country, which is how the US system works.

This would be a mistake I think. The nature of a loan is that the lender can reclaim the asset when a default occurs. This works well for assets like cars and houses but obviously fails for knowledge. Combine that with the age and overall assets of graduates (22 and near-zero) and a bankruptcy becomes a less risky proposition to the student. As more and more default on the loans, interest rates will start to skyrocket, to the point that no one will be able to afford one at all.
As a US citizen, I see the US debt bomb ending it two different ways

1. Sanders/Warren get elected and somehow forgive 1.5 trillion in student loans and make education free going forward.

2. 2008 level crisis

with (2) is the more probable

I think universities tuition is way too expensive in our country, but I'm against (1) currently because I don't think retroactively forgiving debt is a good policy. The students took those loans out, signed the docs, and knew (or should have known) what they were getting themselves into. I think forgiving all of the debt would be obviously ridiculously expensive (1.5 trillion is a lot of money) but also possibly creates moral hazard.

I would be more supportive of (1) if the government took more of a "Canadian pharma industry" approach and just said "this is how much we will pay for this citizen to go to Harvard, take it or leave it". I have no faith that any of the current presidential candidates will be able to negotiate and pass that type of law, so I currently cant support (1).

Is my line of thinking wrong here? I think education should be more affordable but have no faith we have leaders that can get us there.
We, in the US at least, need a privacy Bill of Rights.

Electronic transmission of personally identifiable information and the storage and mining of that data has so many permutations, and technology is so far ahead of legislation consistently, it seems like it’s time for a proper governance framework that exceeds any particular industry, and that has to be based around the individual (I think, there’s more to that).
The scenario you paint is purely hypothetical and far removed from reality. Markets are believed to be mostly efficient. If a business is highly profitable and conservatively leveraged, it will be able to attract capital (either equity or debt)

Finding a business where the fundamentals and the price converge is extremely profitable, it's what all investors, especially hedge funds, do. A large convergence is unlikely to exist in a market system.
I see it's available in Safari Books (for those who have a subscription.) Wikipedia says, "the second edition was released in April 2013."

However, there are mostly 5 star reviews on Amazon, including ones from 2019, so it sounds like it's still worth reading.

People need to leave.

There is a supply and demand problem where there is an enormous demand for a small area when there are so many other great places to be in this country.

Jobs are abundant all over. If you want to solve the housing problems in the bay area, start programs that give people $10,000 to go anywhere else. You'll enormously increase the quality of life of the people who leave.

There's nothing wrong with an area that doesn't aspire to intense density. Nobody is entitled to that, there's nothing wrong with self determination and choosing not to grow. People need to realize there are other places to be, companies need to realize there are other places to be.

Russia tried this 90 years ago. It was awful.

From https://en.wikipedia.org/wiki/Soviet_calendar#Five-day_weeks :

"Eighty per cent of each factory's workforce was at work every day (except holidays) in an attempt to increase production while 20% were resting. But if a husband and wife, and their relatives and friends, were assigned different colors or numbers, they would not have a common rest day for their family and social life. Furthermore, machines broke down more frequently both because they were used by workers not familiar with them, and because no maintenance could be performed on machines that were never idle in factories with continuous schedules (24 hours/day every day). Five-day weeks (and later six-day weeks) "made it impossible to observe Sunday as a day of rest. This measure was deliberately introduced 'to facilitate the struggle to eliminate religion'".[25]"

It is ironic that you bring up the law, because the law … which supersedes any law produced by a wannabe feudal fiefdom like LA, is the Fourth Amendment to the Constitution, specifically "the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated". Please note the "shall not be violated", which is a critical point that is missed about the Bill of Rights in particular, that this right that is referenced in the 4th Amendment is a natural, God given right, which the 4th Amendment prohibits the government from, in this case, violating, or, in other amendments infringing on.

It is seemingly often if not always overlooked that the Bill of Rights it not actually a bill of rights at all, it is a bill of prohibitions on the government, or a bill of rights by negation of offenses against them. From what I can tell, that notion of negative rights, i.e., open ended rights bound by the prohibition of government from violating them, is singularly unique in the whole world.

I would appreciate if someone could point out an example of them same, especially as part of the most fundamental law that governs a state, which even supersede the Constitution itself, a kind of meta-Constitution; natural, God given law that supersedes all Constitutional rights and all powers of government.

You don't exactly day trade houses but it's not that difficult to sell one, otherwise we wouldn't have so many real estate agents. It's a HUGE money source in two ways: who got to a heavily gentrified area first and bought a cheap house, reaped the benefits of good jobs and increasing values for years, especially with how California sets real estate taxes. After 20-30 years of tax-free appreciation they can sell their once 500k house for 2.5M and move to a lower cost of living area.

UChicago 2011 graduate here. When I attended, I paid about $20k/year in tuition, given that I had various merit scholarships, worked for the university, and that my siblings also attended school. My parents were in for a RUDE awakening in my fourth year, however, when my brother graduated his undergraduate program...UChicago found out via a survey, that I was now the sole college attendee, and without warning they jacked the tuition from $20k to $32k for my final year. My parents were absolutely livid and it left a terrible taste in our mouths.

I must say, it was not a pleasant undergraduate experience. On top of being expensive and working very long hours daily, it was immensely competitive and the social life was very poor for me. I have always had numerous friends in life, but I constantly felt lonely at that school, not to mention receiving MUCH worse marks due to grade deflation, which made medical school applications a nightmare.

In hindsight, I absolutely should have gone to my state school, and I'd be a Tesla and a Steinway piano richer for it if I had. I think these ridiculously expensive, 4 year educational vacations need to end...let's encourage our young, bright minds to stay local, to save money, and to use their brightness and talents to lead very productive and EFFICIENT lives.

I've been a developer for almost 2 years (I know not that long) but I have never even heard of bubble sort. Looking it up, it is O(n^2). Is there a reason this is a common interview question? It doesn't seem like a sort one would ever really use, or at least it has very obscure uses.

I always thought merge/quick sorts accounted for 99.9% of use cases and only ever really learned about those.
We do 4-day (32 hour) work weeks at Monograph, and we've been doing it for 3 years now. I believe we're one of the only companies in SF that are advocates for working less, but more productively.

Similar to Microsoft, we only have one 45-min meeting each week and then everything else is heads down work.

To maintain efficiency, we also have strict Slack protocols in place to keep everyone in deep work throughout the day. (No @ or DMs, everyone checks Slack at 11am and 4pm).

The major downside so far has been customer support, which the founders still manage to maintain our response rate.

Hum... How do current prices compare the the 90's? What is the definition of "skyrocket" you were expecting?

Or are you talking about the people that kept saying we'd be back to a medieval economy? Apocalipse fantasizing is a hobby since that book exists; and I'm pretty sure it just had a different name before it, it's not sane to take those people seriously (it's not healthy to fight them either), and it's not sane to pretend everybody is like them.
Debt as an investment is fine. If you are investing in your future with your education, okay, but that requires the education be practical. It must have a value greater than its cost. That is not true for most education and thus we are not investing in our future as a society with this debt.

I'd rather the debt we incur as a society be spent on infrastructure and engineers than wicker baskets. Wicker baskets don't last very long. Roads and bridges do. Engineers do.

Great talk, nice to see people not skim over details
Has it occurred to you that maybe the state can handle the cost? Compare to how much we spend buying fancy equipment to kill people. (Military spending if that is too indirect a description.)

Consider also that a large amount of student loans are already from the government, so in a default...
Don't sell yourself short. The economy could support everyone working four 8-hour days or five 6-hour days at the same pay (or, rather, with the same median pay, better distributed) as now. Our productivity gains over the past 4 decades prove it.

People who want to work more should be able to, but we generally need a massive reevaluation of what work in America is worth, in favor of labor. We're giving up way too much because we're afraid.

I want to hone in on the part about "all of human history".

I don't know if you've met tribes people or those living in agrarian societies, but while they do tend to have excellent work ethics and do a lot, they also tend to have _more_ down time and family time than someone working a 40 hour week, tilling fields is hard fucking work, maintaining all your own equipment and making things by hand is slow and laborious, but you do get to finish. Sometimes there's weeks that you're working every single day, but there's also seasons where you aren't.

I'm completely against forgiving student loans. I want to solve the problem, which means no more Government backed student loans. (I'm all for the Government building more low-cost public Universities, though.)

But if they are going to forgive them, certainly the students who prided themselves on being the best and the brightest should have known better! Therefore, anyone in the top 10% of SAT scores or at the top 100 schools should not be eligible for discharge. If you're smart enough to get into Chicago or Harvard, you're smart enough to know how loans work.
Citizens United totally slipped my mind. Excellent point on the money = speech argument.

Just curious: Have you visited China in recent time? The past few years it's made incredible gains, and it continues moving at a blazing speed.

I think one force that can encourage Pakistan to move forward is China. I don't know if Pakistan can have its own Samsung, but it can maybe 'modernize' with China's help. Would you agree?
No, obviously not. But the point is that there is plenty of productivity to go around—the benefits of it just aren't available to most people.

So, if we were to reduce the ability of the people at the very top to siphon away 99% of the productivity gains we've seen over the past 40 years, we would have more than enough food, clothing, and shelter for everyone, with enough margin that people could also work shorter hours without losing the ability to provide for everyone.

The cost of that is that a very small percentage of the population can no longer have massively extravagant lifestyles.

You can totally get this kind of flexibility as a self-employed contractor. The fact that you aren't just as easily allowed it as an employee is ultimately due to excess red tape in the paid-employment sector, nothing else. Every bit of red tape in the employment arrangement is an extra fixed cost that has to be paid-for somehow, meaning that the employee has to work that much more just to break even.
This is true but mental healthcare can not solve systemic issues that contribute to isolation like a lack of social opportunities or sexual partners. These things can be entirely related to economic factors that a healthcare professional can't address.
