What a terrible advice (sorry). Great comments are not about "what does this code do?". They are about "why does it do it?". In some domains like scientific or high performance computing they are absolutely necessary to

As a user of a product, I do not want to be a community of random people and flooded with unproductive discussions. I do not want to be refreshing mostly-synchronous chats and if missing a day, missing important information. I want compan

Even "compiled" JAX or PyTorch can leave some performance even if you hit the common path (It's also "praying" that the compiler actually works if you do anything non-standard). But memory wise, there is almost no o

There are two main paths to promotion and salary increase: - Becoming a super expert in one domain, or an expert in many. Rare, irreplaceable skillset that is recognized and valuable for the business. Yes, this is vague, but there are tons

This is kind of amazing given that obviously, GPT-4 never contained such tasks and data. I think it puts an end to the claim that "language models are only stochastic parrots and cannot do any reasoning". No, this is 100% a form

Spinning up the Uber App is most likely trivial. Spinning up the legal structure, figuring out all the local regulations and getting permits (it's not 2010 anymore! Many countries and cities regulate ride sharing pretty heavily) in a s

Furthermore, Jeff is not a great (or even good...) manager/director/leader. There were a lot of internal and external dramas because of his leadership, that he failed to address. How often you hear about dramas about other Chef Sc

As someone who's been at Google Research ~5y, this nails is it 100%. I was at the non-Brain part of Research and it was seen as Google Brain is the "cool", pure research one, dealing with some future abstract AI and not carin

That's a super interesting idea and I think should work very well. If it was combined with the use of camera (for tracking the distance away from the monitor / screen) I think it could work very well; especially that noise /

I think it might be the classic distinction between "simple" and "easy". I do believe that most of those problems are "simple" - typically when you read solutions, it's under 20 Python lines of code; and n

I don't know if this translates to other FAANG companies as well, but "washed out too early" doesn't happen at Google. It's very very hard to get fired. You know all the stories of people just "resting and vest

Typically it's based on self reported domain expertise and general hiring interests that you express to the recruiter - to check your competence in what you claim your competence is. But overall the hiring process is slowly changing an

Thank you! :) Yes, I spent quite some time preparing for that post. If you disagree with some of the guidance, I'm happy to discuss (and/or revisit some of the advice)!

My point of reference is very European. In most of Europe you get very distinctive four seasons - cold, sometimes snowy, almost always frosty and depressing winter, fresh and optimistic spring bringing some change, muggy and sweaty, but exc

OP here. I loved most of those, I'd add DNA Lounge (though it seems based on the selection you're not into electronic music :) ). All of those are fond memories of some nice shows. Still was hard to justify a 1h (one way!) drive.

To be honest, all your points sound scary/depressing/unappealing to me. Like the last point - helicopter parenting - kind of creepy to be honest, yikes. But this might be a difference in our cultural backgrounds and how we grew up

Hey, it's the OP here - I explicitly mention in my post issues with having kids in the SFBA / SV (competition, high suicide rates) and being a teenager in the suburbs (I grew up in the city center until moving to suburbs as a ~14y

Hey, I'm the author of the post and I wish I could simply write I disagree with you and how - but you haven't explained how the integer coordinates help aligning the grids, so hard for me to disagree with any specifics. I show how

In image processing we often call those "binomial filters" due to this binomial distribution / Pascal triangle connection. Cool thing is that they both a) sum up to powers of 2, making the normalization divisions in fixed poi

The whole point of my post was trying to answer why such approaches won't dominate (at least short and mid term, who knows long term!). :) We know "costs" of such a change - rewriting every single existing system, tool, offl

My path to research is very uncommon - at least in the US. Being honest it was very disappointing when I tried to switch the industries. Getting a SWE position was very easy (and many ex-gamedevs do it and are very successful at FAANG; many

You are right that "off-the-shelf" engines have tooling and features rich enough that even a single person can make a pretty and fun game. But I disagree with the higher level idea - that this means that things become simple. It&#
