Had a Jane Street phone interview in 2016. "Price a 6-month forward on carrots."
There's no carrot futures market, so I build one from scratch: seasonal harvest cycles, USDA demand elasticity, cold storage decay rates.
One trader stops me. "Your storage cost function– you're modeling the carrot as dead inventory. Like grain in a silo." He asks me the metabolic respiration rate of a post-harvest carrot at 2°C. I estimate.
"Your forward is overpriced by exactly that shrinkage. The underlying is consuming its own sugars. It's alive." Good correction. I adjust the model. I think I've recovered.
Rejection email comes the next morning. Subject: "Ethical Review." My framework, they write, "relied on the severance of the root organism from its growth medium." The question about respiration was a test. The carrot was still alive and I'd built an entire derivatives structure on top of its death without questioning whether harvest was an acceptable act.
I pull up the recruiter's original email. It doesn't say Jane Street. It says Jain Street– a non-violent quantitative commodities fund.
The carrot was never supposed to be priced. It was supposed to be refused. I later learn the only candidate who passed that round was a former monk from Gujarat who sat in silence for eleven minutes and said, "I cannot put a price on life." He's now a partner.

Jane Street made ~$40B in 2025 with 3,500 employees, a ~2x from the year before. At ~65-70% profit margin, that's $8M profit / employee, the highest for a 1000+ ppl company. High-frequency trading continues to be the most efficient money making engine. I want to share an old story about my Jane Street interview in 2014. Jane Street was known for hiring a lot of math, physics and CS olympiad winners from top universities and putting them through many rounds - including, for trading roles, a gauntlet of mental math. It was my 6th interview and my final round and I recall being asked "What is the next day after today in DD/MM/YYYY where all the digits are unique?" They'd toy with you and say "You can use a pencil and paper, if you want" but you knew that was an instant no. Painstakingly and as quickly as I could, I came to an answer. "How confident are you that this is correct on a 0-1 probability scale?" the interviewer said. "0.95", I blurted out, not fully knowing how to answer that. "Are you sure?" After thinking harder for a few more seconds, I realized I could've flipped the digits around to get a closer date. I gave the interviewer my answer. It was correct. "0.95 huh?" he chuckled. That's when I knew I failed. Note: fwiw, other companies that come close in efficiency are - Tether ($90M+ profit/emp) - Hyperliquid ($80M+ profit/emp) and on revenue: - Valve ($50M/emp) - OnlyFans ($37M/emp) - Craigslist ($14M/emp) - Anthropic ($12M/emp, run rate) - OpenAI ($8M/emp, run rate) For comparison, Nvidia is very efficient at scale and is $4.4M/emp.

@cremieuxrecueil This isn't a moral philosophy problem anymore, it's just a frustrating language problem with no answers.
English
@cremieuxrecueil It's a bad problem, because it's entirely devolved into questioning the premise. Ppl make different assumptions.
You assume kids are part of "everyone." Are coma patients? The blind? The infirm? Infants who can't press a button? Uncontacted tribes that don't know what it is?
English
Accurate cartoon.
In my polling, almost 6% of people said they picked the wrong button when they were prompted about it.
Assume the global error rate is higher and kids' responses are random, and easily 1-in-6 to 1-in-5 hit blue by mistake.
So, if red wins, society is ruined.
Jason Boone@shadowe_wolfe
@TheCartoonLoon That's not even close to accurate.

Everybody gets a hundred spam calls a week and somewhere in there is one phone call that actually matters and if you don't answer it you're fucked
We do not have to live like this
aditii@aditiitwt
Had a technical interview scheduled, got two missed calls, and I straight up blocked the number thinking it was spam Now I got this mail... and found out it was the company’s HR calling😭

@ZacharyDonnini This was probably the absolute drop-dead deadline for finishing opinions. Everyone takes forever with their dissents and concurrences these days.

SCOTUS effectively released this decision at the exact moment it could create maximum chaos for the 2026 cycle.
Late enough to force any redraws onto an insanely compressed timeline, but just early enough for states to still attempt redistricting before the primaries. Wild

I had no idea that the SPLC had become a central piece of infrastructure for the Bank Secrecy Act and from there metastisized to become the organizing body for politicized debanking and online censorship

@juliecbarrett The end goal is preventing kids from being exposed to harmful and addictive pornography. States are only implementing "age verification" because adult gooners will fight tooth and nail against an outright ban.
English
The end goal is full state surveillance. The age verification at different levels of the online world are just baby steps to the larger framework. It’s a way to get acceptance from the citizens - who doesn’t want to protect kids from
p0rn??!! - while boiling the frog to full state surveillance
Paul Walsh@Paul__Walsh
Utah’s “age verification” law for porn failed as predicted and is now being replaced with a law targeting VPN users, and it’s no longer limited to kids or XXX. This is how surveillance and control spreads: “child safety” expands into broad control over access and anonymity. 🏴☠️

@kangminlee We gotta upgrade India from subcontinent to full continent, if only to make this particular kind of racism easier.
English
Performative. No one actually views Japanese and Koreans as the same race as Indians or Arabs
All are technically from Asia, but “Asian” in common usage means East to Southeast Asian

@ChristianHeiens If it was ever actually an arguable case brought before the court, I don't think anyone but Gorsuch would readily accept the "technically you ratified this 200 years ago" argument.
English
@ChristianHeiens Probably not "technically pending." The court has never ruled on this sort of thing; the only precedent is the 27th Amendment, which only Congressmen have standing to challenge the validity of.
English
Perhaps the best path that Democrats would have to “ban gerrymandering” at the Federal level would be to get another 27 states to ratify the Congressional Apportionment Amendment, which would cap each House of Representatives district at 50,000 people.
It remains the only amendment that was originally part of the Bill of Rights to not be ratified, and it’s still technically pending before the states for approval or rejection.
50,000 people per district would be akin to having over 6,600 members of the House of Representatives. It would be functionally impossible to gerrymander districts that small, and we’d instead be dealing with an entirely different crisis on our hands.

It's actually very important that ambitious college kids be explicitly told that some prestige careers have low pay *by design* to reserve them for the wealthy, and if you aren't wealthy and want that career you had best believe really hard in it bc you will not be affluent
constans@constans
The tough position to be in is people raised upper middle class, attended a good college, & took a “prestige” media/arts/policy job but whose parents werent rich enough to give them a trust fund or at least pay their rent. They got ahead of what their social class can sustain!
English
@ChristianHeiens Much of our political animosity can be explained by "Democrats feel entitled to win." They aren't supposed to have to fight for it, dammit, why are you fighting back? That's not in the script. That's cheating!
English
Dems: “Pack the court!”
GOP: “Ok”
Dems: “Wait, no not like that…”
Micah Erfan@micah_erfan
The Republican Party *just* packed the Supreme Court of Utah after it enforced the state's gerrymandering ban. Never let Republicans lecture you about extremism.

Criminal policy guy: unions are good, police unions just happen to be bad
Transit policy guy: unions are good, the teamsters just happen to be bad
School policy guy: unions are good, teachers unions just happen to be bad
Maybe these guys should meet!
dandelion georgism 🔰🏗@DolphinMossad
I’ve noticed a habit among my fellow conscientious liberals to take a default position of “unions in general are good, it just so happens that the unions involved in the policy areas I’m well informed about are bad” and never reflect on why that might be the case.

The job of the Supreme Court from 1960 to 2020 was to advance the progressive agenda.
Libs have been out of power for 5 minutes and they’re screaming hysterically how there need to be consequences.
Go ahead, do it, and then the whole edifice can be torched. Libs have way more to lose on this than they have to gain.
Drew Savicki@DrewSav
Is packing the Supreme Court ideal? No but the conservative majority has refused all offers to rule in a nonpartisan manner. If they're gonna keep making partisan decisions then there need to be consequences. Their job is not to advance Republican policy from the bench.

I’ll admit before yesterday I didn’t know there was a law on the books requiring that states draw special little racial enclaves. Sounds completely psychotic to me.

Health advice:
DO NOT let mitochondrial health influencers convince you to start smoking cigarettes
Oxidative State@rudekyoni999
-Nicotine is a mitochondrial uncoupler -Increases testosterone and DHT Paired with aspirin and vitamin c cigarettes might actually be beneficial.

@politicalmath It is, but this is also the plaintiff's case in chief still, no?

@akhivae Bigamy has been illegal in the Chinese empire for millenia. Concubinage existed, but only for the top-top-top upper class.
There was an intermittent cultural practice of bigamy in the North, but legally it was treated as wife+concubine, not two wives.
English
Monogamy was not an East Asian norm until the last century. I knew Chinese-Canadian kids, originating from Hong Kong, who told me their grandfather's were polygamous.
Jerr@jerr_rrej
The high races are monogamous. Western Whites and East Asians. We are inherently monogamous, not taught to be this way. arabs and nigs are into harems. Also Whites in africa or who live around arabs start acting like them. White men will become polygamous because they are wiggers.
