I hate reading comments like this. They’re intellectually lazy and overly cynical. The industry is not a fraud. Yes, shady things happen. But there’s a lot of legitimate research done by capable people. I used to do research in this industr

I can also confirm this. I used to curate data and develop equities forecasts professionally for about 30 or so funds, including Citadel and Two Sigma. It’s getting harder to build a successful trading strategy based on “quantamental” analy

That still seems a little too simple. How are they controlling for multiple people in a household from the same IP address? How are they capable of telling the same person watching TV is performing the activity on the smartphone?

How does Nielsen know 88% of Americans are using a second device while watching TV? How is that data gathered, and how is the research conducted?

It doesn't really function without JavaScript enabled, either. The page loads, but the article is cut off, and graphics/logos don't seem to load completely. There is evidently a lot of JavaScript doing the heavy lifting to di

Yes, and yes. P != NP could be independent from Peano Arithmetic (PA) or the Zermelo-Fraenkel set theory with Axiom of Choice (ZFC) models. That is a separate conjecture which is also presently open.

Security is distinct from privacy. The four mainstream browsers - Chrome, Firefox, Edge and Safari - have the most secure software, regardless of their producers' business models and data hygiene.

I have to imagine you know this if you're reading a book like that; but for anyone else reading this comment: I recommend you don't read Measure, Integration and Real Analysis for a first introduction to real analysis. It's

That was phenomenal, beautiful and intense. Wow. I hope we get more writing like that here on HN. I feel like I've been drinking the author's life from a cup. Spectating his memories right alongside him. What an engaging style of

I can't believe I have to say this, but no, it's not related.

Information theoretically speaking, how do you generate a "synthetic" dataset (as the article calls it) with the same fidelity as an original dataset without having access to a critical basis set of the original? What would you do

I guess this will probably be unpopular on HN, but... I still use Chrome. I don't feel the need to "justify" my use of Chrome. I like Chrome. I care about internet privacy - I use ublock origin and have JavaScript disabled by

Actually, that's exceptionally good performance. You'd be surprised how hard it is to profit consistently even when you have advance knowledge of material earnings results. The market is fickle and lossy, and fundamental analysis

No, my stipulations don't prove OP's point, and it's concerning to me that so many people think they do. Believe it or not, there is a vast underclass of people who live and work in San Francisco who are actually struggling

Can we please stop with the hyperbole? $200k in the bay area is emphatically not scraping by. You can live on your own, without roommates, save money and have a social life if you have a $200k income in SFBA. What people (especially on

I haven't heard anyone say that, but after thinking about it for a second I sure as hell would. A table saw is a lot easier to use than git.

Why not just go to /r/mechanicalkeyboards? There's a big community there already, and if they don't already have a Slack or IRC channel you could create it with them.

Thanks, this is a great comment! You've cleared things up for me a lot.

Thank you, but your last sentence is not really correct. The concept of cardinality captures different sizes of infinity. This is why I mentioned countable and uncountable infinites upfront: a countably infinite set and an uncountably infin

I don't like the phrasing the article used. The domain of the Collatz function is the set of positive natural numbers, which is countably infinite. Unless I'm misunderstanding the quote, it doesn't make sense to refer to perc

As a counterpoint that would imply wolves, coyote and dogs, donkeys and horses, lions and tigers, house cats and bobcats, grizzly bears and polar bears, etc. are all the same species, because they are all capable of interbreeding with viabl

No, neanderthals are scientifically considered a different species from homo sapiens. It's not uncommon for two related but different species to be capable of interbreeding with viable offspring. That doesn't detract from distinct

To be more charitable to the commenter's point, that's not what's being asserted as discriminatory. They're making the claim that it's implicitly discriminatory to penalize people who don't spend time on progra

That's the essence of a DNS rebinding attack, which can be used to bypass server-side request forgery vulnerability mitigations.
