It is understandable that my ethos is not on par with Dr. Walker's, and that my anecdote would indeed make me an outlier.

With that being said, I am legitimately unable to find any conclusive research that says there are effectively three "cronotype" bands, and 100% of the population falls into one of these three bands, and that these bands are completely DNA-driven and non-dynamic. Every source of this information seems to be behind a "buy my book" paywall from some inspirational speaker like Daniel Pink.

The article says:
"For further proof, researchers at Rockefeller University last year announced the discovery of a gene mutation that apparently accounts for D.S.P.S."

In that study, the author says, " According to the new research, the mutation may be present in as many as one in 75 people in some populations." While there might be more genes which lend themselves to DSPS, the numbers from the study don't exactly lend extra credibility to the argument.

Can you help me to understand where it has been statistically proven that 100% of humans fall into roughly three equal bands of morning/evening/between, and that this has been solidly linked to genetics rather than environmental/habits or a combination of both? Most studies on humans don't make such bold claims because genetics are so diverse across populations that the study population itself would need to be enormous.
I agree, and I see this same effect of dismissing an entire specialty based primarily on experience as "easy" even within tech, such as what some programmers (Devs) think of sysadmins (Ops). I also agree that us-vs-them is harmful, and, in the context of my example, it's what DevOps (the original cultural movement, not the current job title) was primarily fighting against.

However, I do think there's some validity to the complaint, hidden in nuance, and dismissing it outright with even the implication that everyone has equal(ish) value, serves to foster hidden resentment.

The allegation seems to be that any accomplished programmer could become accomplished in sales, merely with effort, because the skill/difficulty required by the latter is much less than the former, while the reverse isn't true.

Even if that allegation holds, a question that remains generally undiscussed is, would that programmer-turned-salesperson still be a competent programmer at the end of such a process? Perhaps more importantly, would such a person be a more valuable as salesperson than as a programmer? The question of if such a salesperson is more valuable than a salesperson-from-the-getgo seems to be implicitly answered "yes" in these discussions, but that kind of diversity of experience bringing additional value tends to be uncontroversial.
Does the Audi system work safely in severe weather?
Yeah, it also crossed my mind that once the basic stuff is in place, it frees us up to add more of the niche interest stuff.
Why the throwaway?
Purely from a financial perspective, I think Uber can't possibly admit that. They are gunning for an IPO at a valuation where they are most definitely selling the dream. That dream has to include autonomous vehicles.

I think it's not nearly as exciting a dream if they're just buying the tech like everybody else. Aside from a strong brand and a lot of customer relationships, Uber doesn't have much in the way of assets. Google's got a stronger brand [1] and a lot more customer relationships, as do many others. If Uber is just one of many companies slapping labels on other people's tech, I'm not sure what makes it worth $75-100bn.

This reminds me of the SEC filing for Toyota which I had to pull up earlier out of curiosity

https://www.sec.gov/Archives/edgar/data/1094517/000119312518...

> As filed with the U.S. Securities and Exchange Commission on June 25, 2018

> Toyota and Uber Technologies, Inc. have entered into a memorandum of understanding to explore collaboration with respect to ridesharing. As part of the partnership, the companies created new leasing options in which car purchasers can lease vehicles with connected terminals from Toyota Financial Services and cover their payments through earnings generated as Uber drivers

So not their first rodeo, Toyota sells cars after all

Also Toyota Connected is making quite a big splash in Europe at the moment with a London office having been established March 2018 to soak up local talent.
​Zowe Bringing the mainframe to the open-source world
The car didn't do anything wrong, emergency braking was disabled and relied on human intervention.

Now why it was disabled is another question. Most likely because their system isn't anywhere near ready.

The only value I see from the whole of Uber is know how and practical examples of how not do solve this. The fatality didn't change anything, it is (and was) painfully apparent that it was only a matter of time.
To be clear, we don't ask candidates 'what is a relational database', and I'm totally in agreement that that's a weak interview question.

The other reason specificity is a legal issue is that it provides data that can be disputed. For example, if you reject someone black and say the reason they were rejected because hey didn’t get far enough in the coding test — you’d better not hire the white guy who only got just as far (which might happen for a variety of reasons).

It’s almost the same reason you stay quiet when held by police. Even something seemingly innocuous may end being used against you in the future.
I don't blame Epic at all for avoiding the Play store. I find it patently unacceptable that two large tech companies now act as gatekeepers for software releases.

More like 5 - Nintendo, Microsoft, and Sony all control what software goes on their platform either digitally through their console app stores or physically since all media has to have keys from the console makers to run.

Sure, it provides extra security, but at a heavy cost.

Seeing how the last 30+ years of personal computer use has played out, the vast majoriyy of users should probably be using locked down devices.

And Epic provided the perfect example of why app developers should be forced into a strict sandbox. I need my phone to always work it’s much easier for me (but not most people) to recover from a virus/malware/ransomware on my computer than a hypothetical one on my phone.
You ever been to a beach?
If you/your company doesn't have a policy of sending personal feedback please consider doing this at least for junior people. Volunteer your after work time if needed.

Trying to find the first job is extremely stressful process. A junior person has no notion of his worth on the market. Each rejection even if only by a lack of any response ("I'm sorry, I'm afraid we are looking for a bit more experienced person" would suffice) can be like a kick on the face when you're just barely learning to walk and most likely is a burned bridge.

I've mentored my girlfriend for 3 years from almost 0 to getting her first job in a company run by a React Native core developer. She had the skill, great attitude, really solid work ethic and very analytical thinking. It'd trust her more with any task than significant number of my past and current senior coworkers. It's hard to prove and no one expects that so naturally her applications had been ignored or rejected. With each one I saw her confidence, self-esteem and enthusiasm crumb. With each positive reply/invitation she was invigorated until the next step came. I'm pretty sure for some the roller-coaster or even worse, being rejected over and over again can be a life defining experience.

Any reply is great, personal is even better. If you spend time describing what was missing from the expectations of your company (don't say "You don't know enough", say "We need someone with more knowledge") and sincerely wish the person well you can be sure they'll be grateful, remember you, work on the gaps and who knows... maybe some day become part of your team.

Please feel free to reach out if you want some example for inspiration.

Edit: Please don't do that against the policy of your company. But if there are no reasons against just ask if you could provide some feedback and resources for the rejection letter.
A good example is 'multi-patterning.' With >16nm processes, a single mask layer had minimum pitch/width requirements you had to follow (i.e. wires must be at least this thick, and spaced at least this far apart). Now, multiple masks using horrendously complicated interference patterns are required to make the smallest layers (I think 7nm might use quad patterning, so 4 masks per layer at the finest pitch), so your mask costs just went up 4X, and your yield got worse. But that's not all! Now you need to think about which wires in that layer are part of which of the 4 masks (typically called the 'color' of the wires), so there are additional weird rules about the pitch between wires of a given color, all of which means it's just harder to design with, and it's harder to actually 'use' the increased density of the smaller features.
Amazon warehouse envoys rally to tweet upbeat comments
"Poisoning pigeons in the park" by Tom Lehrer

Spring is here
A-suh-puh-ring is here
Life is skittles and life is beer
I think the loveliest time
Of the year is the spring
I do, don't you? 'Course you do
But there's one thing
That makes spring complete for me
And makes every Sunday
A treat for me

All the world seems in tune
On a spring afternoon
When we're poisoning pigeons in the park
Every Sunday you'll see
My sweetheart and me
As we poison the pigeons in the park
When they see us coming
The birdies all try an' hide
But they still go for peanuts
When coated with cyanide

The sun's shining bright
Everything seems all right
When we're poisoning pigeons in the park
We've gained notoriety
And caused much anxiety
In the Audubon Society
With our games
They call it impiety
And lack of propriety
And quite a variety
Of unpleasant names
But it's not against any religion
To want to dispose of a pigeon

So if Sunday you're free
Why don't you come with me
And we'll poison the pigeons in the park
And maybe we'll do
In a squirrel or two
While we're poisoning pigeons in the park
We'll murder them all
Amid laughter and merriment
Except for the few
We take home to experiment

My pulse will be quickenin'
With each drop of strych'nine
We feed to a pigeon
(It just takes a smidgin!)
To poison a pigeon in the park

Ask HN: Why is Docker useful?
I have several Python web apps hosted on Heroku (Flask & Django). After hearing a lot about Docker, Kubernetes and containers in general, I began to wonder whether I need them or not. Can you please explain what is the perfect use case for Docker is (or other container tech for that matter)? What is the utility of using it? Does it worth the additional complexity? Thanks!
Dissenting opinion: I dont think net neutrality is a good policy. Very light users(news) are effectively subsidizing super heavy users(netflix). NN is just popular because it was removed not because it's a good policy.

I think internet should be sold per GB, at different tiers of speed/uptime/ping. This gives an incentive to companies to give you faster speed and provide levels of speed/ping that people would be willing to pay extra for.

Something like:
Browsing tier: .1c/GB 1mb/s 500ms ping guaranteed
Video tier: .3c/GB 100 mb/s 100ms ping, 99.9% packet delivery
Video conferencing tier: 100 mb/s 50ms ping, no packet loss

etc... Don't focus on numbers but rather the idea.

A 15km underwater line is not a problem.
Why isn't Epic at fault for dishing out insecurity on a platform that contain's a user's everything? If instead it Google wasn't in the picture at all, but an unknown hacker who disclosed vulnerability, would it still make sense to divert blame from Epic? I personally would still blame Epic.

Similarly, I also wouldn't care if a random hacker or reputable firm disclosed Target's vulnerabilities when they put millions of customers at risk. I'd blame Target by a big margin.

Sure, people don't need to explain RDBMS frequently, but that code you wrote last week? Or that reason you can't do exactly what the PM wants? YMMV but I spend a LOT of time communicating difficult concepts to other engineers (not only mentoring juniors, but also just doing hand-offs and stuff to others), to product managers, sales people etc.

Some engineers really do sit in a quiet room all day writing code, but my experience has been that it is an extremely communication-centric job.

Either way: if you do work in the kind of environment where you need to work with other engs and teams frequently you do need to test communication skills, and simply coding is not always sufficient.

AFAIK Audi's driver is legally allowed to keep hands off the wheel in specific circumstances. Meanwhile Tesla's driver is theoretically driving even when "autopilot" is engaged.
I am actually stunned how there was no displacement of the current input devices.

We fitted keyboard onto our screens, AR devices normally come with a joystick or something.

I have high hopes for similar projects to Tap Keyboard or the Myo armband, that continue to evolve on something that IMO has large implications on how we can evolve as a society the same way smartphones did. A wearable input device that was _good_ (defined by not being cumbersome, probably even fashionable and functional, as should match current input) would be for me the extra step .

If they send feedback which tells candidates, truthfully, that they were rejected because they didn’t get very far on the coding project, then if anything a company reduces their legal risk: they have a transparent track record of evaluating candidates based only on their skills

I think the problem comes when he talks to his friend of another race/gender and that friend said "Yeah, I couldn't finish that either, but they still hired me". The company may have had a legit reason to overlook the coding project (like the second candidate had experience in some other technology), but when you tell candidate X that they didn't get the job because they didn't complete the coding exercise, but then you hire candidate Y despite him not completing it, it provides candidate X with some concrete evidence of discrimination.
Off shore drilling rigs aren’t anchored to he floor, but the pipe could literally snap if the rig floats away.

They are kept in place solely by GPS and thrust vectoring.

The Ruskies are going to use the same technology here, known for decades, and probably safer than oil rigs since there nothing to snap and a small volume to protect if the whole thing sinks.

All the ways I discussed in the article - more nuanced, more thorough, more detailed, more focused on constructive advice you can take to your next interview. Plus, we've just improved our process in general so you aren't tested on skills you don't need. It's easier to give constructive feedback about an interview process you have a lot of confidence in, and much of the work we've put in as a company over the last few years has been designing an interview we think really works.
> - "Rosatom, in a statement, insisted its plant was 'invulnerable to tsunamis.'"
> Really ?? why are they trying to sell dumb electricity when they have the much more valuable technology of invincible ships. How many tsunamis has one of their ships survived exactly ?

A 10' dinghy in deep water is pretty well invulnerable to tsunamis. Invulnerability to hurricanes would be an entirely different proposition.
That's quite a claim without numbers.

It looks like part of the point of this post is to illuminate/explore that hypothesis. Or, is that how you're interpreting his findings?
Several studies have been made on immigrants net contribution to the public sector. With the low immigrant unemployment rate and a smaller share of the total population, the studies concluded that immigrant net contribution to the public sector was either negligible, neutral or slightly positive up until the 1970s. With increasing unemployment rates and a larger share of the total population, this was shown no longer to be true in 1999 by Ekberg

>in the case of disaster, it can be dumped into the ocean, which is somewhat better than contaminating occupied land, but still isn't acceptable.

dumping the stuff into ocean results in spreading the stuff around the world. It is much more preferable to keep it contained - like in case of Chernobyl's 30km exclusion zone at least we have a chance 100years from now when technology allows to clean up the zone - no such luck if it happens in the open ocean. Fukushima is still fighting to contain the stuff on site and don't let it get out to avoid making the disaster into a global one.
If your devs are often explaining basic stuff like 'what is a relational database?', you need to hire someone specifically to do that. It's not a good use of time especially when they can go google/wikipedia those concepts and figure it out themselves.

If you can’t communicate ideas and basic concepts to non technical people, you will both limit your career opportunities and not be able to get your ideas implemented while someone with worse ideas will.

Developers underestimate the amount of influence you can have just by being able to communicate effectively.
I think what gets a lot of people too, in addition to this math, is that they think "Oh, 6 pints or less per week is safe? I'll have them all on Saturday then."

There really need to be a very clear outline on how much is safe to drink, by day, by week, by alcohol content per volume, etc. Just throw a explicitly detailed chart out there.
> I dont think net neutrality is a good policy.

I don't think you have a correct definition of what net neutrality, as a policy, is. See below.

> I think internet should be sold per GB, at different tiers of speed/uptime/ping.

This is perfectly consistent with net neutrality.

What is not consistent with net neutrality is pricing the same GB/speed/uptime/ping differently, depending on which endpoint the traffic is coming from/going to. That is what net neutrality regulation prevents, and all that it prevents.
Also, these are small plants; not the amount of power that would cripple a country.

Make its e-supply more reliable, yes. But not replace the bulk of the supply. For that Rosatom will sell you a few GW units on land
No.

This predicates meaningful access to the internet on your socioeconomic status, further entrenching extant divisions. Educational material is increasingly being delivered in video form. What happens, e.g., to poor families have to choose between paying the electric bill, or buying food, or buying enough download capacity that their kid can learn?

But that's not even the real issue. The big problem with a non-neutral internet is the barrier to entry imposed on non-incumbent players. Netflix has the money (and customer base) to absorb any "pay to play" costs imposed by the end-user's ISP.

Whiz-Bang Startup Streaming Service doesn't, unless they take more funding, meaning the people who created the thing own less of it, and all of that additional money goes to the incumbent ISPs.

I submit that this is an intentional outcome of the policy.
He named a specific person before the edit, which is a bit different. Nothing wrong with naming/shaming digg.com, though.
>I heard back from many of the engineers I write to, and often, they were furious

Bingo. I've opted to share specific team feedback via phone and although candidate feedback was generally positive and thankful, once in awhile the reaction would be extremely negative. I now opt for the much more (emotionally) safe route.

Triplebyte is more incented to provide candidate feedback because if the candidate improves, Triplebye may be more likely to place them in the future. With companies, this incentive is less apparent.
I think everyone can agree with you on the "per GB front". NN does nothing to prohibit data plans which cap at some GB limit. The issue is, the carrier shouldn't get to decide the weight of different GBs. It's about all bytes over the network being equal. If you use the internet mostly for news, you can always opt for a smaller data plan. I don't see how you get forced to pay for someone whose content is of different nature.
Ask HN: What is your favourite programming commmunity?
Is it irc? Online forum? Slack? Why it is your favourite?
You shouldn't trust any single study. Researchers are not perfect, reviewers are not perfect, the systems they observe are complex. Even in the "hard" sciences even if the experimental data itself is solid there can be confounders that were overlooked and will only be uncovered by follow-up studies, depending on importance of the result it might take years.

That's why have meta-analysis and systematic reviews and even those aren't exactly bullet-proof.
Hopefully we see a visit to Australia/New Zealand in the future.
Please elaborate. From where and how do you get the traffic data from, and is it sufficient?
Yes, the low quality and outcomes of public education are very bad, and a political system that insists on dooming a majority of kids to that hellhole is very bad.

The positive solution is not to seek to destroy what decent educational systems may still exist. Have you considered that it is public schools that need radical change, to be more like private schools? or even to become private schools?
