Dr_tldr··on Ask HN: How much do you make at Amazon? Here is how much I make at Amazon
Your experience with small to mid-sized firms does sound depressingly typical and I've experienced it too, but I think it's worth mentioning that Amazon specifically won't reject you for not saying a number.
Dr_tldr··on Ask HN: How much do you make at Amazon? Here is how much I make at Amazon
The OP is being kind of cagey about what their role is. Nearly everyone at Amazon who does what we would generally be considered a primarily dev role is either an SDE (Software Development Engineer) or a WDE (Web Development Engineer). Are you a support engineer, by chance?

As for salary negotiations, the best piece of advice I got was to never say a number. You really don't have to, you can just keep saying some variation of "industry standard", their median salary numbers on Glassdoor, etc.

This is true for Amazon specifically: I never told them a number despite being asked by several different recruiters, and the offer I ended getting was slightly above their average. If you want more than that there may be some other technique involved, but if you're more concerned about being undercompensated, definitely don't get tied to any number.

Dr_tldr··on Study: Immigrants Founded 51% of U.S. Billion-Dollar Startups
It's no secret that the continuing economic dominance of the US is not due to a post-WW2 windfall or the unique capabilities of Americans, but more to the ability of the US to attract and retain the very best, and then subsequently give them unique opportunities.

Few nativists are opposed to the best and the brightest (and the already-wealthy) coming to the US in very, very small numbers, but what they don't realize is that it's pretty much impossible to tell in advance who's going to be a winning lottery ticket.

Dr_tldr··on Evidence that Alzheimer’s ‘lost memories’ may one day be recoverable
I did some digging into Dr. Bredesen's work and the study you mentioned didn't have a control group. If you don't have a control group and you're changing dozens of variables simultaneously, you're not doing science.

This is not to say that his patients don't enjoy some subjective benefits, or that diet and exercise and mental stimulation aren't helpful, but Dr. Bredesen cannot have any scientific insight into Alzheimer's until he does an actual study.

Dr_tldr··on Not a Black Chair: racism, sexism, and discrimination at Squarespace
You're comparing a child to an adult as if they're the same. That's a pretty leaky abstraction and somewhat disturbing if you can't see the critical distinction.

This is the kind of self-indulgent thinking that tries certain (usually poor or minority) 12 year olds as adults, while treating certain (usually wealthy and white) adults as children who should be forgiven for "youthful indiscretions." Similarly, it focuses on the comparatively well-off but unhappy while completely effacing the experiences of the genuinely exploited.

Dr_tldr··on Not a Black Chair: racism, sexism, and discrimination at Squarespace
Saying your company is at fault for how you feel is the exact same reasoning as "You made me do it", ie, not assuming any agency at all. Same thing with "toxic culture of abuse."

People who are being sexually trafficked and child soldiers are in a toxic culture of abuse that they can't escape from. We're talking about an adult with a lower management job at a tech company, not the wretched of the earth.

Dr_tldr··on Not a Black Chair: racism, sexism, and discrimination at Squarespace
Squarespace really sounds like a nightmare, and also very rough on people who work a support/call center role rather than a dev role. I say this having experience with both, as only the call center involved handling tickets as a primary activity, and having a regular night shift (rather than being on-call every few months).

On the other hand, this sounds pretty grandiose to the point of being delusional:

"Squarespace, you hoped I’d be another black woman in the tech industry who would quietly watch as you grow in power while I wither away. You are mistaken."

Squarespace: a company actively dedicated to the withering of black women in tech. That's a pretty extraordinary claim, so it needs some pretty extraordinary (ie, non-anecdotal, verifiable) evidence. The adjectives used to describe literally every other person in the story are mostly if not completely negative, and this ultimately weakens the writer's claims.

Dr_tldr··on Study Finds No Gender Gap in Tech Salaries
>"Why is "trend" relevant? Your clarified statement is that modern wage disparity is not due to discrimination. That means that even a handful of counter-examples would suffice to show that that statement is incorrect."

That does not logically follow. If you're offering an explanation for a large dataset which is depicting a trend, the value of that explanation is not undermined by a handful of statistical outliers. If we say that the explanation for women living longer than men is a mixture of biology and cultural factors, a single story about a woman murdering her husband does not speak to the accuracy of a broader explanation at all.

You would need to demonstrate that the counter-examples and the counter-explanation they suggest are statistically significant.

Edit: I'm not engaging in an ad hominem attack here, but I would like to draw attention to previous comments made by this poster to indicate that this is not the first time they've had difficulty parsing how statistics are generally understood to work: https://news.ycombinator.com/threads?id=dalke

Dr_tldr··on The Sign Up with Google Mistake You Can't Fix
The solution you're looking for is OAuth. It's in fact never been "all or nothing", its' always been a choice by each app and service. The reason most apps ask for everything is because 99% of users don't understand or care, and if you try to explain it to them, they'll get confused, bored, or nervous, and not use your app.

"What's nice about OAuth is that it allows the end user to control access to information and revoke access as needed."

Users are free to revoke their their permissions at any time, but they won't be able to use an app without the permissions. You could very easily build a UI with user-variable permission scopes on account creation/management with OAuth, but no one bothers, because it would be a pain to manage on the backend for zero economic gain.

Dr_tldr··on Free React.js Fundamentals Course
I don't know how much the course goes into this, but it might help you get started to keep in mind that it's not HTML in JS, it's xml-like JSX syntax as syntactic sugar for regular JS function calls.

It's no more "embedded HTML" than something like $("<p>").text("lolwut").appendTo("body"), just written with a different syntax. Good luck!

Dr_tldr··on React Armor: Protect your DOM from third-party tampering
Yeah, I genuinely don't understand what they're going for here. Anything that happens client-side can be modified by the client. Because, you know... it's on their side. Front-end validation and stuff is nice for UI/UX, but nothing that comes from the client should ever be trusted just because you put an obfuscated property on an input or something.

At the end of the day, it all has to be valid HTML tags and javascript that runs without crashing. In terms of security, nothing on the front end even registers on the scale. Absolute worst case scenario, it's like solving a Wheel Of Fortune where I have most but not all of the the letters.

I'm pretty uncomfortable with the description of a user on their own machine, running their own browser running plugins they chose and installed as a "third party" that's engaging in "tampering."

Dr_tldr··on Is Blind Hiring the Best Hiring?
It really, really depends. If you've got a large team and a mature codebase, a rockstar programmer who's a douche is usually worse than useless.

But if you've got a small team and are making major architecting decisions, the competent, meticulous, anal-retentive jerk can be perfect. A good manager knows how to get the best work out of everyone, and managing different/difficult personalities is an important skill.

Dr_tldr··on How to Make Users Think Your App Loads Faster
Pretty much all the usability testing that's ever been done would disagree with you. Do you have a good reason for feeling like your opinion is representative of broader demographics?
Dr_tldr··on Why Are Ultrasound Machines So Expensive?
"And if there are indeed windfall profits to be made what is preventing smart-ass entrepreneurs from jumping in and making those profits?"

Incredibly high barriers to entry and very large established players who have already cornered the market? Following your logic, oil companies must not be very profitable since there aren't very many entrepreneurs buying their own offshore drilling platforms.

"They aren't profitable the way people make them out to be."

Who are these people? What is this way?

What concrete assertion are you refuting? How do you explain the P/E ratios of the biggest medical device companies?

If the cost of regulation is such a drag on profits and innovation, why are medical supply companies that primarily serve the US market so much more profitable in the long term than their counterparts in other countries?

Are you alleging that there's a bubble, or that they're cooking their books, or that they're not one of the most consistently profitable industries?

Notice the comments on the article that are over a thousand days old? Please don't inaccurately title submissions "2016" when you're uncertain (and in this case, very wrong) about the date.
Dr_tldr··on Why Are Ultrasound Machines So Expensive?
My portfolio is about 50% medical supply and machinery manufacturers, and they're incredibly steady investments which pay strong dividends even and especially when the stock price is down. Furthermore, they're often able to make biotech plays and their guaranteed revenue means they're strong candidates for acquisition: http://www.bloomberg.com/quote/HSP:US

Do you have any sources for your claim that regulatory compliance is hurting profits beyond a one-off anecdote? Because my experience has been that it's an industry rife with windfall profits.

Also, what's the name of this Indian company, and what's the brand name for the device? If it does what you say it does, you would be pretty foolish not to invest.

Dr_tldr··on Spotify moves its back end to Google Cloud
It may have started as an ass-covering move, but I also think of it as a common courtesy for letting people know that you're offering non-specialist advice and to take it with a grain of salt.

I kind of wish people did that for more things: "I am not theologian/windows user/empathetic person, but..."

Dr_tldr··on Technical interview performance is kind of arbitrary
That doesn't seem to correspond to the attitudes of salesmen vs engineers. I'm not sure what salesmen you're thinking of, but few of the people in sales I've talked to can have an in-depth discussion about how React.createClass vs Class ___ extends React.component will effect "this" context, and how super(props) pattern works in the latter. Furthermore, lots of engineers who work with any given language/framework can't explain it either, and many of them have basically been copy-pasting until stuff worked their whole career.

I've found that most people who have poor communication skills are not good engineers either* and the two might actually be related.

*Except for substack

Dr_tldr··on JavaScript's popularity appears to have peaked
I have yet to meet a human being who has used Dart, or could identify its syntax.
Dr_tldr··on The Husband-And-Wife Team Behind the Web’s Most Infuriating Outdoor Retailer
And this is why Amazon or REI should remain the preferred option even if the price is higher or the selection isn't as specialized. It's really strange that people would think online shopping is now a universally safe and hassle-free activity just because some reputable merchants do exist.
Dr_tldr··on Too many people have peed in the pool
Blizzard gave us six inoffensive emotes, and we still find a way to engage in asshole behavior with them. It's kind of inspiring, actually.
Dr_tldr··on How Silicon Valley is dealing with mental illness
> Did you know that psychologists know how to cure insomnia in a single session?

I've spent quite a bit of time and money working with psychologists, psychiatrists, done sleep studies and kept up with the latest research, and there's nothing I'm aware of that would support your claim.

So, I have a few questions for you:

1) Peer-reviewed sources?

2) Are you concerned that making these kinds of claims non-anonymously without publishing any data to back it up could cause you to lose to your medical license?

I hope it's "doesn't waste time on clickbait."

Titles like this are against the HN Guidelines, last time I checked.

Dr_tldr··on Why the Assholes Are Winning: Money Trumps All
I'd agree, but a common doom-mongering narrative is "things are worse than they used to be and they're getting ever worse!"

Very few people say "the present has a number of trade-offs that's arguably not much better or about as bad as the past." That said, I think a lot of the gains are invisible to white professional class heterosexual secular/christian males, which is part of the problem.

As a pure issue of labor, the average work conditions are probably the same or worse than in 1970 and purchasing power is about the same. Both of those are bad things that need to change, but there are vast cultural and technological improvements that often get diminished, and I think the comment above is a pushback against that, which does advance their argument.

If you only identify with the historically most privileged group, a lot of the advantages like "not being provided with inferior safety equipment because of your race" or "living in constant fear of your career being destroyed because of your sexuality" don't seem very important. What seems "toxic" to the most privileged group can seem like "acceptable tradeoffs" to other groups, and this also speaks to the attitudes of many immigrants and H1-B employees.

Dr_tldr··on Xiaoice, a chatbot that may be the largest Turing test in history
I would like to see more granular numbers for how long people spend talking with chat bots, because that's a distinct possibility! I've seen numbers like "x thousand hours of conversation", but my impression is that it's tens of thousands of people messing around with it for 5-10 minutes rather than anyone (or no more than a few outliers) spending any significant amount of time with it.

As for the reddit irc bot, that's a genuinely cool and useful project, but that's querying a curated dataset rather than having a coherent conversation or identity, so I think the intentions are fairly different. On the other hand, if you had a bot that only queried the comments made by a longtime user, you could get a pretty life-like effect!

Dr_tldr··on Breeding back
More a novelty than an actual scientific undertaking, since most "breeding back" currently being undertaken is just selecting for a few of the most prominent physical features.

It's an interesting idea, but I would guess we'll have better luck with direct genetic manipulation of embryos and then using the existing species to birth them.

Dr_tldr··on Xiaoice, a chatbot that may be the largest Turing test in history
Isn't the biggest problem between a human and a bot is that they have nothing to talk about? The bot isn't from anywhere, it doesn't do anything, there's no reason for the conversation, and the bot isn't aware enough of context to speak about a topic in an intelligible way.

For my money, the most realistic chat bots will be the customer service ones: you have a reason to "talk" to them, they have a fixed identity, the context of your conversation is clear, and you share a common goal.

Dr_tldr··on Homejoy back as Homeaglow
Did they solve their untenable business model of assuming that cleaners are interchangeable service workers AND assuming that cleaners aren't smart enough to cut out the middle-man who literally does nothing after the initial introduction?
Dr_tldr··on Pitfalls of self-guided science (2004)
This really speaks to a lack of infrastructure for people who are interested in scientific topics beyond the generalist level provided for in US schools. If there had been a legitimate and clear pipeline for him as a teenager to be mentored by a nuclear engineer, none of this would've happened.

I had a friend with similar proclivities and eccentricities who was fortunate enough to have a father that worked at Oak Ridge National Laboratory. His studies were directed and safe, he was able to visit the lab on a regular basis, and he ended up going to MIT and becoming a nuclear engineer. It's entirely an issue of access, and a lot of times you literally have to be born into it, which seems like an inefficient system.
