I found the comment both slightly racist, and harmlessly humorous. Some stereotyping can be funny and acceptable. I would’ve found it similarly both racist and harmlessly humorous if the author was going to a party and said “I channeled my

You are doing solo, technical, concentrated work. I have seen a lot of people do more and better. But different work, not coding. Like leading and managing people is very possible for some elite people to do for say 70 hours a week and mos

What’s true on average might not be true for certain individuals, and power-law mechanics might make those individuals more significant than everyone else who makes up the average. Like imagine Elon Musk works 80 hours a week and he doesn’t

There is a great episode of Jocko podcast with Andre Huberman that just came out where he carefully addresses this specific issue. Worth listening to (it’s in the first hour or so, I mention it because it’s 5 hours long!!)

I just wish there was an ergonomic way of saying “Please check if the following code can possibly panic, and fail to compile if it can.” That would allow critical sections that happen to use a library not to need to audit all the code in th

Hey, I just wanted to say that your comments in this discussion are awesome and I’m having a lot of fun reading them. Thanks!

> Netflix, SpaceX, JPL Interesting list of examples, I wouldn’t necessarily have grouped these together? Have you applied for these at some point? I haven’t, but the emphasis seems quite different at each company

I think the author did the right thing here: pick an arbitrary cutoff like top 20, and assume that within that bucket they’re all pretty good, without worrying too much about the specific ranking of each school.

Back when Flash Boys came out, we all started calling each other Flash Boys. There was then a serious proposal to rename one of the strategies (the hedger, for added irony) Grandma Annihilator 3000. When the KCG thing came out, one of the

How about: * Listening to each person’s specific concerns carefully and in detail, and then applying as much creativity and empathy as possible to help them come up with a resolution? * Giving people increased responsibility and increased a

The attitude that finance pays more is a leftover from a previous era. 10-15 years ago it was true: the profits from HFT were so also way, way bigger and split up amongst a much smaller group of firms. Now those firms are all in a complete

Just wanted to say thanks for sharing these rules, I think they’re super helpful. Do you have any particular rules about performance? I worry that accepting net improvements on functionality alone could result in “death-by-a-thousand-cuts”

I agree with your sentiment, in fact the skin tones especially are a massive liability. Like if you mis-click by a few pixels in your corporate Slack, and all of a sudden you send the wrong colour thumbs—up emoji, now it’s A Situation.

I think the point of this was to remove the genders, right? To avoid offending the people who get offended if genders like male and female are acknowledged to exist?

Just a follow up on a practical way to actually do this: turn each “User” into a 30-minute conference talk with a slide deck showing techniques you used, performance metrics, etc. Pitch them to the various JS conferences and go give the tal

To reply to those saying CPI inflation is up 60% over the period: S&P500 is a better measure of inflation, up 3x over the period, so navy budget roughly keeping pace.

The two of you could probably bootstrap your expertise into a non-VC, multi-$M ARR Javascript performance consultancy, taking peoples code and finding 5-10X speed ups through better JavaScript. You could have a great lifestyle and a great b

Can’t speak for OP, but for certain low-latency applications like trading, one wants to isolate a core, pin a thread to it, and have that thread spinning hot on some condition (maybe network card, maybe IPC), for optimal latency in respondi

Not nitrogen-cooled, but liquid-cooled overclocked rackmount servers (with consumer gaming CPUs rather than the usual Xeon CPUs) are a thing in HFT. They’re crazy because they are so unstable that you basically can’t reboot them and expect

I think this is a great interview. I do something similar. I’ve done most of my interviewing in finance where: 1. The engineers are mostly really good 2. They almost never have side projects, and everything they have ever done is super sec

It’s a shame that Domain Driven Design and Data Driven Design have the same acronym, while being basically polar opposites (some people call the latter Data Oriented Design for this reason). To me, Domain-Driven is sort of an extension of O

This doesn’t really answer your question, but gleaning it from job descriptions is one way I do it. If I’m curious how a company did something, searching for their job descriptions can turn up interesting stuff like what languages and frame
