yes, when I got my job at google I had basically memorized CLR (I was a biologist, not a computer scientist, so I had to do a bunch of extra reading).

Yes, that is also correct. Toxic behavior is present for a variety of unrelated reasons of which many can be cured with a humble dose of self-reflection. Sometimes that lack of self-awareness becomes catastrophic in extreme cases like Bathsheba Syndrome.

People occupying positions of management are more capable of seeing trust issues simply because they have the responsibility to talk with subordinates of their own and reason upon the effectiveness of that dialogue. People without managerial experience generally lack the tools to perceive the behaviors driving the decisions thrust upon them. People outside of management also tend to lack the necessary exposure to situations where these behaviors are present.

There is also the power dynamic. A boss can more easily terminate a toxic employee than an employee can terminate a toxic boss. This power distance prevents many toxic employees from establish trust issues against a superior until there exists a pattern of identifiable behavior beyond a single employee.
Bright idea: instead of letting kids vape (harm profile: uncertain, could be low), let's hook them to drugs like Varenicline (Champix) which are known to cause thing like cardiovascular diseases and suicide ideation.

(Actually, it's a bright idea for all the parties involved, because "think of the kids" brings positive karma points, and parents and insurance plan will cough up the money)
this article is all over the place...

- spent $100.000 on personal branding, but what was spent on building the instagram following and what was the ROI on that part?

- "If you wanna know how to get to a million followers, it’s not complicated." so why does he only has 118.000 followers? did he give up before reaching his goal?

- "And guess what? Thanks to that exclusivity, he’s the most searched-for term. If you type “Seth” into Google, “Seth Godin” is the first search result. " first of all no he's not and second of all he's not in the suggestion list because he doesn't broadcast his mailing list. would have been nice to see some reasoning behind that statement.

- "It cost me $1,000 to speak at All Thing Social Media Event or at Soho House on growth hacking. I was able to generate at least $10,000, in some cases even 100X on my spend." is part of the sentence is missing? how do you get 1000% ROI from such gigs?

Could I sign up 10 times and use statistical regression to get very accurate results?
I was on a nuclear sub from 1996-1999, so it's possible that my observations are no longer valid or don't apply to surface ships. But I suspect that my assessment would be the same even today. I worked with enough surface sailors to see that the amount of bullshit work they did was comparable to ours, and they didn't have nearly the physical space limitations that a submarine does.

It's not so much that we were doing "unnecessary" work, but rather that many tasks which required a dedicated person were so trivial that any reasonably competent sailor could easily handle two or three of them at once, or the task could be even more reliably automated.

One quick example is the fathometer operator: When we were sailing in shallow or uncharted waters, a sailor had to spend hours doing absolutely nothing but watching the depth gauge so he could give a verbal warning if we were in danger of running aground. This is not a job that requires a person's full attention even in the most challenging undersea terrain.

To some extent it's necessary to break jobs down into simple repetitive tasks so that they can reliably be done in a high-stress environment, but the navy really took it to an extreme. The end result was the overwork and fatigue that others are referring to.
That's called a cartel.

CNBC is a major news organization, so they generally should be using English correctly. I think a blog post can have technical errors here and there, but the standards for a proper news article are higher.
Here's Arnie's bio:

Arnie Gundersen has more than 45-years of nuclear power engineering experience. He attended Rensselaer Polytechnic Institute (RPI) where he earned his Bachelor Degree cum laude while also becoming the recipient of a prestigious Atomic Energy Commission Fellowship for his Master Degree in nuclear engineering. Arnie holds a nuclear safety patent, was a licensed reactor operator, and is a former nuclear industry senior vice president. During his nuclear power industry career, Arnie also managed and coordinated projects at 70-nuclear power plants in the US.

I think we could safely say he's a whistleblower and exactly the right kind of person to be commenting on nuclear power.
I don't know about math, but in CS, a lot of funding comes from specific grants, so you'll be working on something related to what your advisor got grant funding for.

Let me defend the philly suburbs for a second here:

The actual philly grid extends _quite_ far out, ~hour drive outside city center. On top of that, the light rail goes WAY outside in a bunch of key directions, with rather impressive bus connections.

Don't get me wrong, as a now-seattlite I would be remiss to criticize robust road transportation (god knows ours isn't) but I think you're looking at Philly through the wrong lense. I never needed, wanted, or had any friends who wanted a car while living there (especially since more modern tooling like zipcar and now ridesharing), and I miss that greatly. I don't think I could manage the commute I did via public transit alone in many cities other than some of the NE hubs you mention. (I'd add boston in too, at least back when I was there the T+Bus connections were great)
I'm not a biologist so I'm basically making this up, but my guess is no. I think only false negative errors are possible because of the way they do their sampling.

If two samples had enough similarity to say someone is a child of someone else, my guess is that's pretty accurate.
Haha, very interesting. I've always wondered what would happen if I sent in a sample from my dog.
>Tesla starts building Gigafactory in China

Tesla didn't start to build anything. The Chinese government put them on notice because there was no work done. So, of course, Elon flies by himself to China to put on a grand opening show and says they'll start production in a year.

How is it this community, who prides itself on being so smart, can fall for this?

No car factory has ever been built that fast. How can it be in production in less than a year? Where is the money coming from? After the disastrous Model 3 launch, are there still people on the planet that think Musk knows more than the incumbents about building a factory? Remember 3D assembly lines and robots so fast you'll need a strobe light to see them?

It's astonishing that people are still buying into this story.
You do not offer any citation as to why this, the chip based genotyping, leads to misinterpretation and the article does not suggest this is the reason either. Without getting into it, the article says

>An entire DNA sample is made up of about three billion parts, but companies that provide ancestry tests look at about 700,000 of those to spot genetic differences.

>According to the raw data from 23andMe, 99.6 per cent of those parts were the same, which is why Gerstein and his team were so confused by the results. They concluded the raw data used by the other four companies was also statistically identical.

>Still, none of the five companies provided the same ancestry breakdown for the twins.
Disclaimed: I used to work in this field, but not on the Apple Watch.

The wearing a bunch of them at the same time is going to be wrong, yeah. Wrist mounted fitness devices are calibrated to read on the top side of the wrist. Even reading on the bottom side of the wrist would be a bit different, way up the arm? Very different.

It is possible to make accurate devices that read there, they just need to be constructed to do such!

Wearables are also meant to give an accurate rating over the long term. If you go running for 30 minutes, are the overall calorie burn, average HR, max HR, and min HR, all correct? Tracking in perfect sync with the heart is nice, and of course everyone tries to do that, but if the number is off for a second here or there, well so long as the overall result is the same the usefulness hasn't really changed.

Finally, due to the way optical HR works, random unexpected, movements are really hard to deal with. It can take some time for an HR sensor to lock on to the heart rate. This isn't too long (measured in seconds, and each generation of devices is getting better and better), but it relies on regular patterned movement, such as arms pumping while running or walking, the regular motion of a bench press, etc.

Stopping and checking the HR value every few seconds to see if it is correct is literally the worst case scenario for a lot of wrist mounted sensors!

Ground truth is strapping a heart rate strap to your chest, putting on the wearable, going for a run as you normally would, and comparing the two at the end.

Multiple sources have done this, and found the Apple Watch to be best in class when compared to directly measuring HR.

tl;dr: Stopping and checking wrist mounted devices can confuse them, Apple Watch, and everyone else in this field who is serious, are tested against HR straps and they come within spitting distance of accuracy.
I agree, I would not have survived math in school without being able to ask other people.

I learned programming on my own from books but I don't think I could do that with advanced math.

If this was some random person and not Feynman we wouldn't be having this discussion. It's hard to reconcile important people, good people, our heroes doing bad, despicable, evil things. But there's good and bad in all people. Good people sometimes do bad things and vice versa. People are complex and flawed. It would be easier if we could view everyone in black and white, but it's not realistic.

Just remember that Feynman's questionable, despicable behavior toward women doesn't invalidate his work in physics. Conversely, his important work in physics doesn't make up for his abuse of his wife.
> I'm not sure what being software developers has to do with it.

For example by providing a safe way to whistle-blow. Or by making encrypted communication more accessible (Decades after PGP invention, e-mail crypto borders on unusability). Or by fighting against laws that mainly serve to introduce censorship. Or, by not helping governments censor or manipulate their populace (hello Cisco).

The biggest enemy for a corrupt government is journalism and whistle-blowing.
When capitalism is the problem...

It’s just like therapy now. Don’t get me wrong, therapy can be very good, but I feel like a lot of people are going to therapy because it’s the only way to get respite from their capitalistic hampster wheel.
Mine also changed after I complained that the results were obviously wrong. It indicated that several of my chromosome pairs came entirely from my father. Since that's generally impossible, it put the rest of the results in doubt.
I did this a few years ago, now doing an MS in math, after last formally studying math in high school, more than 20 years previously.

There is lots of advice in this thread, including long lists of books - at your level, I think that’s unhelpful. To get started with the foundations, I think it’s best to have one or two books at most, that you work through completely, then decide what to do next. Otherwise you can waste a lot of time time figuring out “what to do next” instead of actually doing math!

I would personally recommend “Engineering math” and “advanced engineering math” by Stroud. The first covers “foundation” topics like algebra, trigonometry etc, then covers the first year of math for a English engineering degree. The second book covers the second year.

Note that English engineering degrees are 3 years vs 4 in the US, but have no general education requirements, so the math covered in the two books is roughly equivalent to the 1st-3rd year of an engineering degree in the US. Both books are very much focused on calculations, not proofs, but will give you a fluency in handling mathematical calculation that is assumed when doing more proof-based courses later. And they are both designed for self-study, which is important.

The other book that I would get, and do in parallel once you have done the foundation part of the first stroud book, Chartrand, Mathematical proofs. This will teach you how to do proofs, using mainly (high school) algebra and basic number theory to start, but going on to cover some proof techniques in analysis, advanced algebra and others areas.

Once you have done those 3 books, you will have a solid basis for further study. I also agree with the comments about interacting with others studying the same material if possible.

> in a space they'd either like to be in as well

But that's exactly what monopoly means, i.e. you can't get in and compete with those players.

It sounds like you are justifying monopolized markets for whatever reason.
> have no proof, but I guess it allowed women to more accurately value themselves in the market, therefore helping them pair up with other high income men, and causing home prices to go up where dual high income households tend to congregate.

This makes sense to me. Even more so if we make the assumption that it's easier to be a married couple making $200K combined (e.g. 125K and 75K) vs one member of the marriage making $200K.
>Auto companies routinely let broad swaths of employees go

This is the second round of layoffs in less than a year. Growing companies with infinite demand don't need to lay people off.
In theory yes, in practice Amazon has a lot of catching up to do.

I don't know about the situation in the US, but by now every big food retailer in Germany has a delivery service, ALDI included.

These food retailers already have all the supply&logistics in place due to their physical stores, the delivery business is just an extension, all of it often heavily sourcing from local producers. In the long run, these companies can shift their main business to deliveries, turning their retail stores into mixtures of store and distribution center.

In that context, I don't see how Amazon will easily be in a position to get similar products, at similar prices, without having at least some physical retail presence. They got the logistics down, no doubt about that, but I think in terms of actually sourcing fresh, and local, produce the established food retailers have quite an edge on Amazon.
I think there's two reasons:

1. They're partially insulating themselves from price changes in the chicken market. By raising the chickens themselves, they can guarantee that they'll only pay a certain price for the chicken they raise.

2. Fewer intermediaries = lower prices since there's fewer companies that each need to make some money = higher profit
Depending on your background, you probably don't have enough information to pick a long-term goal anyway.

I am afraid that sounds curmudgeonly, but I have also seen students shoot themselves in the foot because they decided they didn't need a class for their not very well informed goals.
I pretty much believe this is how tech will evolve in general. A small group of big companies will completely dominate tech, consolidating talent, power, and money. They have so much cash that they will buy out, or copy and dismantle their competitors. Even in the valley, so called cradle for tech innovation, the way of thinking for a number of years has been to create tech and sell it to a big company. This is the end game for all capitalist societies in general, in every area, the consolidation of everything by the few over the many.
It would take so many errors adding up that I think it would be very impossible. Has anyone ever had a real sibling not come out as around 50% related?
I also went to high school in the United States 20 years ago, and have parsed my experience very differently than you. There were many morality and justice declarations about everyone but the United States, and then just...silence about the morality of US actions. They wouldn't say the US did wrong under any circumstances.

I didn't learn about the firebombing of Dresden from History class, I learned about it from Vonnegut. I may have learned about the bombing of civilians in Hiroshima and Nagasaki in my history class, but their moral dimension was summed up by "It made Japan surrender," which is ahistorical bullshit. I didn't learn about the Tuskegee syphilis experiment at all, nor much at all about the racial prejudice that dominated American culture for a hundred years after the civil war (and continues to have lasting effects today).

American History as taught in US high schools is hagiographic, make no mistake about it.

Okay, this is true. Using alloca directly is not a good alternative.
This is pretty interesting, and thanks for the link. This is now making me think how people with ADHD (like myself) can use this to understand how they think. I just read people with ADHD can start creating false memories with situations because they may not have been paying attention in that situation, but I don't want to go on too much of a tangent.

The original article is something really exciting to read, the more that we can understand about how we can navigate through our mental space would help so many people and it's really cool to think about.

Random thought is if you can apply network theory to the hexagonal array or the grid like pattern? If it can be, my first thought would be to apply Triac closure and other principles to see how memories are tied to one another and the connections between them.
Mitochondrial DNA chimeras?
Haha, man, would that be a terrible way for the human race to go. Driven to extinction just because a few men really only cared about their own lifetimes. It would be highly amusing.
No amount of schooling could have truly prepared you for precisely how similar twins' DNA would be. Shockingly similar.

"Mono" means ONE. Literally the number 1. Monopoly generally means ONE supplier that controls the entire marketplace.

There are other forms of market failure relating to a small group having too much power in the market: Monopoly, Cartel, Oligopoly, Monopsony, etc. etc.

Oligopoly or Cartel are far closer to what the article is describing. To use the word "Monopoly" here is simply incorrect English.

Good evidence? Elon himself said it.

And yet outsiders denied it then, and are still denying it. This company is in a cash-crunch.
> A single person can just sign up twice for these services and get different results

Do you have any personal experience with this? Or anything you can cite? I'd be interested.
Ok this is new to me.

So these people getting results and finding out they aren't related to their parents, are the results suspect?

Ditto the results about genes associated with dementia or heart disease?

I'm aware of the companies having disclaimers, I thought that was on the basis of them not really know what the genes did, not that the test itself was rubbish.
I think you are right on both points. There were more details and his answer was just a quick way to say:

He didn't care about the status of having a PhD

He didn't need a PhD to advance his career

He was having fun doing math stuff anyway
Regardless of grants, etc., your general area of work is going to be based on what the faculty members' focuses are. But in any case, you'll probably still be doing your own sub-piece of some larger effort. You wouldn't choose an advisor at random, so this isn't really relevant.

I mean, if you're interested in astrophysics, you shouldn't go to a school where the Physics department is focused on nuclear physics!

"Monopoly" literally means there is only one player in the market, or that one player has a hugely dominant position.

Sears would have probably died without Amazon's involvement. Its decline started a long time ago, when Amazon was a small fraction of retail sales.

Between that, and Lampert stealing every valuable bit of the company that wasn't nailed down, or could be pried off, while actively starving their core business - it never had a chance.

Polar is basically a personal knowledge repository.

The idea is that you use Polar for all of your education. Either official education or continued learning.

Every textbook or technical paper should go into Polar.

You can then annotate the textbooks directly including text highlights, comments, etc.

It supports spaced repetition systems like Anki so you can continually review what you've learned and NEVER forget anything.

It doesn't make sense to pursue a PhD or spend 6-12 months researching a topic to just forget 80% of it due to bit rot.

The reason I named it Polar is that it's meant to 'freeze' all of your knowledge so that you never forget it - ever.
As I understood it he expected the different results were due to contamination or other errors resulting in compromizing the raw data to some degree. The shocking part was that the raw data was ok while the results weren't ok to the same degree.
