This article made me _really_ curious what manner of awesomeness is going on at Two Sigma, but couldn't figure it out from the website. @spf13, any pointers on where to find a good article on why TS is cool?

Can’t speak for two sigma but I work in a similar company. They are generally only open enough to hire people, there is a huge competitive advantage in sharing as little as possible. Lots of finance firms have a bunch of interesting problems, from scaling to security and many are getting better at treating engineers well. But usually it comes down to the fact they pay really well.

What kind of engineering culture do they have? Can people continue down the technical route without needing to jump into management?

Two Sigma is notoriously tightlipped about everything. This guy's short post about interning there in 2015 is probably the most I've even seen about working there: https://evjang.com/2015/08/17/internship-experiences.html

In terms of "tightlippness", they don't come close to TGS Mgmt. All of their employees can't even list their employment at TGS Mgmt on LinkedIn.

I worked at a firm who had the same policy in 2014.

It was more common than you may have realized.

One of the few places that will pay competitive to GOOG.

*Much better than Google. Two Sigma is one of the top paying companies: https://www.levels.fyi/leaderboard/Software-Engineer/Entry-L...

They pay _interns_ $70 per hour

I'd hope so; it would be pretty damn embarrassing if you couldn't do a slightly advanced fuzz buzz.

A tree is just a type of graph. A graph can be represented as an adjacency matrix. So come up with that matrix, then drop it into lapack for inversion. Lapack is well optimized so this is probably a very good solution.

I haven't thought about this before, but I can't see how this would work. Instead, you'd convert to an adjacency matrix (with edge directions by only populating the upper rectangular region), then transpose the matrix, then convert back to a graph. The transpose should swap the i, j pair edge directions. Matrix inversion is super-expensive and I think it would produce somethign else entirely, probably not unlike matrix decomposition, which can extract centrality properties of the nodes. But it's super expensive.

Depends on the role, in general they’re not going to blow Google out of the water.

Two Sigma (and others) have been poaching senior level google talent at a quicker and quicker clip. Very exciting to watch the exodus happen!

Hedge funds/hf trading companies can't compete with monopolies in printing money. I wonder how they are getting all these people.

Snowflake and Databricks also hoover up a bunch of engineers, snowflake in particular extracted a large number of extremely senior folks. I assume they match base comp, offer equity, and then give people a lot more freedom than they would have at BigCo.

GOOG is no longer known for high pay. Given the same level, even Meta has exceeded Google pay for a long time now. That's not to mention hedge funds like Two Sigma or Citadel.

Wow! Jealous much. His LinkedIn says he started at MongoDB in 2011. The first commit to Hugo was in 2013, a full two years later. Your story doesn't add up at all.

Jealous? NO. Someone just needed to finally call him out on his bullshit. He left in the middle of 2014. He was checked out for a long time. I'd say that timeline adds up pretty nicely. So while Steve would like take credit for Mongo's enterprise adoption he barely had anything to do with it. Not with the Server, not with Cloud, not with Sales, Marketing or Education.

What a strange world 2022 is, wherein former employees of MongoDB openly catfight on HN over who was most responsible for suckering some of the Fortune 500 into buying a truckload of technical debt. Arguing over that like it’s taking principal credit for achieving sustained cold fusion. Baffling.

We all contribute to poop. Our level of contribution to said poop does not diminish that, in fact, we all work on poop so we’re all in the same poop boat. Take it easy on each other, and reserve the bullshit calling for those who really earn it, like the folks who initially built the poop you’re claiming by cleverly offshoring their minimum maturity on the financial and sweat equity of every early adopter. Like, say, for example, for no particular reason, my team at the exact time you’re arguing about.

It’s fine, though, I get it, that’s valley capital, fake it until you make it, give us ops teams ulcers, we make goodish money. Just weird to see resentment over who can claim MongoDB success with that kind of perspective is all. Particularly since the success at the time was all lazy developer mindshare (no disrespect, I’m lazy too), and the technical weaknesses started a few ten-year roadmaps that are now in the market and obsolete MongoDB.

“I led the team that designed MongoDB’s pioneering user experience."

Let's break this down and I'll explain why he is a total liar and bullshit artist.

This makes it sound like he designed the mongodb query language. Only he could pass off inflicting the crappy Drupal website as designing MongoDB's pioneering user experience. He can't be talking about MongoDB the company, it was 10gen so obviously insinuating it was the DB.

The entire Driver and integrations ecosystem had to be cleaned up. His mess. Was barely ever in the office.

MongoDB user manual? You mean the book that Kristina wrote - who worked on the Server team and had nothing to do with you.

Yep! It was not a serious suggestion, just a joke based on taking a circuitous route through the language.
