This is an excellent observation.

The problem isn't hyperrationality per se; it's a lack of intellectual humility and self-awareness. The behavior you're talking about arises when someone looks at a problem, immediately wants to fix it and makes snap judgements to figure out how to do so. Instead, they should dispassionately consider 1) whether the problem is fixable in any meaningful sense, and 2) whether they have the requisite experience, skill and insight to solve it in five minutes of thought.

You could further distill this idea with the observation that a lot of people consider things too systematically, rather than holistically. "First principles" thinking is a powerful drug, which appears to crack open the world and solve every problem. But no problem-solving paradigm can deconstruct away unknown unknowns or inexperience.
Pretty hard for companies to not skew very heavily towards being about making money when people require money for food, shelter, and healthcare (at least in the states).

Unless the people involved are in a financial state where they are not dependent on revenue from the company, or we divorce survival from capital, I doubt it's really possible for "not making money" to disappear as a terrifying core motivator for every business and every employed person regardless of whether their marketing copies are disingenuous.
Yep. The optimal strategy depends only on the relative ordering of elements, not on their magnitudes or any other property. So the strategy is the same for any continuous distribution.

(With a discrete distribution, the possibility of ties slightly affects things. But in this particular game, ties seem to be very improbable, so they can be ignored.)
"why don't you accept that people have to work longer? the population is not booming anymore so you cannot accept future generations to pay. "

Well that is a political choice. There are option possible where we don't work longer, and option where we work longer. According to the option money and worked are not shared in the same way.

Both option are possible - e.g. different economist have different personal preference.

The only think we have to is to have a debate, and a democratic decision.
I've thought a lot about this too (I used to work in HFT). Here's what I think:

- The only part I didn't like in your article was how you described creating indicators as exploitation. The limit order book is public by design so all traders can look at it. People have the free choice to trade on a centralized exchange or not. This is a trade-off between revealing information and being able to trade quickly without calling all your friends asking if they want to buy some Bitcoin.

- I'm guessing you used data from other exchanges outside the one you were trading as indicators too. That's unquestionably good since your trading helped information propagate faster or more accurately than it would have otherwise.

- Markets are only zero-sum in isolation. Most participants derive utility from things outside short-term profit and loss. Maybe they trade to manage risk, to hedge, to gamble, have a longer time horizon than you, whatever. They just want to trade and get back to their lives. They don't want to waste time squeezing the last fraction of a basis point out of their fills. It's hard to believe, but they actually enjoy getting picked off, run over, paying too much spread, whatever things make you feel bad or indifferent about the service you provide.

I used to get filled making markets on Nasdaq (which pays resting orders a rebate, and charges crossers) when BX (which pays crossers a rebate) was at the same price, and could lay off the trade for an instant profit. The people who traded with me paid for the luxury of saying "fuck it, send it to good ol' Nasdaq." I used to think it was stupid of them, and from the perspective of a prop trader, it was mind numbingly stupid, but they probably had more productive things to do than read every exchange fee schedule or hook up to every small exchange.

- Providing liquidity has nothing to do with resting limit orders vs. crossing the spread. Providing liquidity is about taking risk off the hands of people that don't want it, and moving it across time to someone else who does. If you're market neutral, trade many round trips every day, and end relatively flat, you've played that intermediary role as a liquidity provider regardless of what order types you use.

- Crossing against mispriced orders is doing the world a favor. You're not the bad guy picking them off. If anything, they're the bad guy for holding the market at an incorrect price.

So maybe think of yourself as more of a service provider. Not only will you feel better, but viewing trading through that lens tends to make you a better trader. Strategies truly built around an exploitation mindset are fundamentally unsustainable, since you run out of people to exploit. Providing a service works forever.

FWIW, the rest of what you wrote is almost exactly how the pros do things. If you built this system yourself, you could make far more than 200k at a prop firm. If you're interested, reply with a throwaway and I can refer you to a friend who's still in the business.
Exactly.

> Unlike Theranos, Sight Diagnostics is starting small and working its way up. Holmes claimed her device could do hundreds of tests across the four main classes of blood tests: hematology, immunoassays, general chemistry and DNA amplification. Sight is only focusing on a subset of hematology for now.

So, in truth, they're not anywhere close to trying to do what Theranos promised. The book Bad Blood goes into the technical details that made Theranos's mission fantastical if not farcical. The scope of it is very different.

This was one of the most telling passages for me in Bad Blood:

Tim [Timothy Hamill, Vice Chair of UCSF's Dept of Laboratory Medicine] confirmed to me that both practices were highly questionable. He also explained the pitfalls of using blood pricked from a finger. Unlike venous blood drawn from the arm, capillary blood was polluted by fluids from tissues and cells that interfered with tests and made measurements less accurate. "I'd be less surprised if they told us they were time travelers who came back from the twenty-seventh century than if they told us they cracked that nut," he said. (p. 230)

I was just asking. You are putting "travel expenses" @ $xxx which doesn't seem to include your rate; so it should be how much you spent to "get there". If you want to charge extra (and I think you should since it's time you spent for the client) then maybe put "travel expenses" + "x hours spent traveling".

I disagree any of them were underpowered. The PS1 and PS3 arguably produced the nicest graphics of their generations - the PS1 because its competition was compromised in their own way, and the PS3 due to sheer brute force.

The PS2 for sure was less powerful than the more conventional architectures of the GameCube and Xbox, but it was released 18 months before either of them in a time when Moore's law was still extremely relevant. Yet it could still hold its own against the competition. All pieces of impressive hardware.
In France, more than 60% of unemployed people over 58 stay unemployed until retirement. So pushing away the retirement date only worsen the situation. There are simply no jobs for the elderly.

Unemployment dropped dramatically thanks to the 35h work-week. They provably created at least 350000 jobs ( https://lexpansion.lexpress.fr/actualite-economique/les-35-h... ).
SNCF (the rail company) is something like $45 Billion in debt?

Their conductors can retire using last 6 months of wages (vs avg wages)?

They can retire at 52? So payments will go to 82 (france has great life expectancy) That's 30 YEARS of pension payments!

They are guaranteed a job for life?

They get free / low cost housing?

They get 28 regular paid days off an maybe another 22 or so RTT days? (ie, 50 paid days off before any sick / unpaid etc).

Not bad!

These articles always start with a description of how hard the job is. In Europe they actually have great automated safety systems for trains and the trainsets are in good condition. I realize it's a hard job, but boy - my heart goes out to greyhound bus drivers in the US and many many other workers with no where NEAR these benefits and frankly much harder jobs.

Google is doing well. Some of their older investments (like AI maybe) are already making them money.

And they have a few bets that with time and some luck could make them a lot of money.

It's very likely they would be able to cover their investments, at the very least.

And they have ackuired many new capabilities as a result.

It makes for a better financial future, a stronger company long term, and also, contributing so much value to the world is simply a good thing.

Consider a two digit number. With this algorithm, half of the numbers generated will be less than 10, and half will be 11-99.

Likewise with the full 100 digits this algorithm has a 1% chance of generating a number less than 10, while the correct proportion would be 1e-100.

The algorithm also does not generate numbers with zero in them (presumably to avoid leading zeroes, but this will skew results somewhat).

I think the correct algorithm would be to generate 100 digits and then remove the leading zeroes.

1) Some of these chemicals are found in quite small concentrations. The fact that we can detect them reliably is actually rather remarkable.

2) Generally, the full blood draw serves as an averaging filter. We know that concentrations of chemicals in the body vary significantly with time, position, etc. Pulling more blood over several seconds serves to average some of this out.

I do not recommend doing that. Instead, you may wish to either use the plain "urn:uuid:" format, or use a different URI scheme (such as "http") with your company's domain name. A company does not normally have only a single UUID; you can make up additional UUIDs as needed. (If you want to avoid collisions, you can use version 1 UUIDs.)
If it was normalized, there wouldn't be a problem. You'd just index the subscriber list and postgres would handle the = or in queries properly.

The distribution chosen here is ~ uniform for the number of digits. (https://github.com/victorqribeiro/googol/blob/master/js/main... )

This is not the same hypothesis as the problem stated in the video. The video talks about the "secretary problem". In this problem you know nothing about the distribution. You just know that the number are ordered.

Here because you know the distribution you can do better by using a strategy which choose to stop depending on the value of the number you have so far.
For example if at the 15th pick you get a number with 99 digit, you can safely assume that it is better to stop now (every time you pick you have only a ~1% chance of finding a 99-digit number needed to do better so keeping it means you win (99/100)^(50-16) = 70%, whereas the non-exploitable strategy (i.e. optimal strategy for the secretary problem) 50/e=18 will tell you to keep going and you would lose 70% of the times).

For the secretary problem the theoretical way to sample the number is to set it up as a game where the first player plays the game and the second pick the numbers adversely so that the first doesn't win. A good strategy for the second player is to pick a distribution from a big set of varied distributions, and sample the number from this distribution.
no, you're confusing (and trying to redefine) basic economic concepts that are generally well-understood and well-defined by economists (particularly you're conflating profits with rents[0]).

by definition, profits are rewards for productive use of capital, while rent is the income gained from simply having capital.

some lazy and greedy market participants (e.g., plutocrats) contrive to rent-seek, but capitalism (and economics in general) considers such a misallocation of resources the worst kind of economic sin. so yes, there is something wrong with that.

capitalism expects such situations to be short-lived, as compeition drives such profits to zero. if that doesn't happen, then the market is distorted (by some expression of power).

I love the initiative of transparency for the fund, I really appreciate the manual and it’s a crazy trove of insights for potential owners.

That being said, I dislike the experience of going to Github for the info, clicking a link, having a Medium article open up, it just feels fractured and hard to maintain in the long term.

Basically, really like the guide but I feel like the fund could use some money to build a better... collaborative book.

I also have a problem with their decision to invest in companies that basically they feel have a chance for shooting for the stars, but that’s their fund decision.

Would love if anyone can provide similar insights to this VC whirlwind going on.
You have a strange definition of "differently". A millionaire doesn't get to speed, that's just ridiculous. They'll be stopped, inconvenienced, and have points on their license, and eventually lose the legal right to drive.

Treating people differently through some arbitrary definition of difference is wrong. Either we're all equal in front of the law or some animals are more equal than others. And the kind of justice you're peddling is what has set countries across the world on fire recently; the uneven application of the law.

[Edit] I don't think I was clear. Everywhere we see special cutouts in the law, all that happens is that the more capable less scrupulous people capture those cutouts. The best we can hope to do is to treat everyone exactly the same in front of the law.
