pedrosorio··on Homebuyers must ‘learn to live’ with near-7% mortgage rates says RE/MAX chairman
If you’re curious (many HN readers are) and have basic math literacy (ditto) once you come across the concept, grokking interest rate risk takes about an hour at most.

pedrosorio··on Homebuyers must ‘learn to live’ with near-7% mortgage rates says RE/MAX chairman
Doesn’t the bank have the right to refuse to grant a mortgage in the first place, depending on the asset? It’s not like you tell them you’re buying a house worth x and they give you a mortgage for 0.8x, right?

> But what is really unacceptable to me is how you dismiss their viewpoint because they are a 2nd-year CS student!

> Saying that an author lacks the authority to write about a topic is a variant of ad hominem

This is not really about authority. An outsider can have good ideas. A person who has no experience and no knowledge of the subject will usually spout nonsense as seen on this thread.

If someone was talking about how child birth doesn't need any sort of pain medication because the experience isn't that painful, wouldn't you want to know if they had actually given birth at least once?

Concretely, reading what a person who has never worked a full time job (much less had to juggle having a family and a full time job), has to say about work-life balance is pointless.

Reading their thoughts on how not working overtime precludes raises and promotions is a waste of time.

Watching as they finish their rant by appealing to a sense of duty that every software engineer must have because "if Google or AWS goes down, it breaks everything" when the people responsible for these systems are a tiny minority of all software engineers...

Come on. If OP was not a 2nd year CS student, I would have been surprised.

> I don't think making humans comfortable is the goal with respect to AI

According to whom?

AI in games, has historically been all about human comfort/enjoyment. Extremely good AI that seems "unnatural" to humans is usually not the goal.

> half way through elements of statistical learning

If you're able to make it that far on ESL, mathematical background certainly won't hold you back when learning anything "neural networks" related. Specially not a spelled-out practical intro.

> I know basic python (read python for data analysis)

You may want to get more comfortable with programming in general (outside of the data analysis realm), but you can learn everything you're missing while watching Karpathy's series (and referencing the python docs).

pedrosorio··on Once hailed for decriminalizing drugs, Portugal is now having doubts
> I think it's fair to say that alcohol does far more harm to the user than psychedelics

I agree but also think that’s a very different statement from “alcohol is a much more dangerous drug than most”

pedrosorio··on Once hailed for decriminalizing drugs, Portugal is now having doubts
What does Portland (Oregon?) have to do with Portugal?

> Crime — including robbery in public spaces — spiked 14 percent from 2021 to 2022

I wonder what else changed between 2021 and 2022 that could have caused robbery in public spaces to spike.

So many things have changed in Portugal over the last decade, Lisbon and Porto in particular, that looking just at drug policy is insufficient. In particular, cost of living and immigration from poorer countries (both correlated with “number of desperate people”) have risen significantly.

> alcohol, a much more dangerous drug than most

The overall impact of alcohol on society is not because it is “much more dangerous than most”, but because it is consumed (and abused) by orders of magnitude more people than almost every other drug.

pedrosorio··on Learn how to design systems at scale and prepare for system design interviews
> but it empirically performs the worst with a roughly 50% correlation to on-the-job performance. You’re better off flipping a coin because at least then you’re not biased.

I was going to point out that a correlation of 50% is pretty good (specially for predicting job performance from a single interview), whereas flipping a coin has 0% correlation with anything that is independent of the coin flip (such as job performance).

You probably meant to say the probability you rank job-performance of two random candidates correctly based on an interview is about 50% (what your source calls "percent concordant"), a correlation of 0%.

Out of curiosity: do you remember which section of the book looks at "chat about tech" interviews compared to other kinds of tech interviews in regards to their job performance prediction capabilities?

pedrosorio··on Top Talent, Elite Colleges, and Migration: The IITs
Yep, in many situations intelligence beyond a certain threshold isn't the limiting factor. That's the qualifier missing from the first comment that I addressed. In some situations (that HN members may be disproportionately interested in), it is and it matters.
pedrosorio··on Top Talent, Elite Colleges, and Migration: The IITs
Perhaps I shouldn't have mentioned a specific name. The point is, some things are impossible to do unless you are extremely smart.

So, in response to your first comment, "it doesn't even matter how smart you are" is not accurate unless you specify the context you're referring to.

pedrosorio··on Top Talent, Elite Colleges, and Migration: The IITs
> it doesn’t even matter how smart you are

If you care about being "happy"? Sure.

But plenty of things require a bit more than "a surprisingly low threshold". You're not going to be Jeff Dean (for example) if you're just "smart".

> one in a thousand

That's probably way too high of a threshold. Many standardized tests lump everyone who is in the top 5-10% of ability, as long as they prepare sufficiently well.

That being said, addiction is not easily cured with or without free housing, if the substance of addiction is easily available nearby (alcohol, drugs, casinos) without additional support systems.

pedrosorio··on Japanese police make first YouTuber arrest for uploading video game gameplay
Yeah, I am aware of Nintendo's fame of not being particularly friendly to fans and defending their IP in ways that seem excessive.

But to be clear, the statement in your original comment that I quoted

> you can just look at Nintendo who to this day still goes hard after Youtubers who just cover their games

(emphasis mine)

is false, right?

If that's the case. What are all of these gameplay videos of their most recent release doing on youtube (all of them uploaded by foreigners afaict)?
