This is a completely side comment, but I don't understand why stories about Jane Street keep making the front page day after day:

Today: https://news.ycombinator.com/item?id=50467297

Yesterday: https://news.ycombinator.com/item?id=50455394

Two days Ago: https://news.ycombinator.com/item?id=50438261

It's a bit odd (?!).

I posted this. I'm just a regular dev, without any kind of attachment to Jane Street, in fact i'm a little wary of them, and would subscribe to Evan Czaplicki's understanding of the faustian bargain working there would involve. I think they're banned from India, if you want an example of the kind of raiding they are equipped to do.

In general - I am wondering how engineering interviews change in the age of LLMs, Jane Street, tech-wise is a "thought leader", at least having opinions, sharing them is part of how they recruit "the best", i think oxide does this too.

So in some way, in this time of change it makes sense that they are noisy... It also makes sense that the noises they make may filter down...

There are three Jane Street stories on the front page right now. This one, "Socratic Tutor (github.com/janestreet)", and "A false smoke alarm almost drowned Jane Street's only NYC datacenter (bacarella.com)".

What I learned over time is that first, the pool of people who regularly submit to HN is surprisingly small, so if they have interest in a particular set of topics, these topics are overrepresented in the queue; and second, relatively few people patrol new submissions and the the first 3-4 upvotes in the first 15 minutes decide if something bubbles up to the front page or not. These folks often go by keywords / vibes / employer associations, so again, certain topics get an advantage that's unrelated to the merit of the story.

More generally, I think there's been a significant drop in topic diversity on HN over the past year. Almost everything on the front page is related in some way to AI or to companies on the forefront of AI. It's almost as if there's nothing else going on in tech or in the broader world. If you go to some other aggregators, you get a different view.

They pay a LOT of money, have some high level of “nerd” prestige for solving interesting technical problems, have good outreach with things like problem of the month, and have not been impacted by massive layoffs.

There are pretty few companies out there like this. Being relatively small probably helps; everyone knows someone that worked at Mag7 and maybe has a bad story to share, but this is more rare.

All three stories fit the criteria of gratifying one's intellectual curiosity, which is goal of Hacker News submissions.

Consider this: Would you find anything unusual about seeing those stories on the front page if each came from a different company or didn't mention the company name at all? I wouldn't, because each of the submissions is primarily interesting for the content, not the company associated with it.

I think Jane Street has gained prestige and notoriety in the last few years. For people like Math majors who are split between tech and finance, it’s the most famous I think.

Noticing a bit too much

What is the deal with it though? Daily front page content in various forms starts to raise eyebrows.

That may or may not be suspicious, but Jane Street has been posted here a lot since forever, mostly because of ocaml.
