> To be useful for discriminating between competent candidates,

I helped redesign the code challenge at one of the companies I worked for. We (the people across the different technical disciplines we hired for) put a lot of effort into ensuring that:

* the challenge could be completed in 4 hours
* the challenge resembled the sort of work people would do on the job
* the goal of the challenge was to inform a follow up interview, not punish people
* candidates were explicitly told that they were not being timed, but that we expected the challenge should take them up to 4 hours to give an idea of the upper-bound level of effort expected

The single biggest challenge was balancing "what do we need to know" versus "what would we like to know" versus the amount of time we were asking of our candidates.

We didn't hard-fail anyone unless they were blatantly not a good fit from their submission, and I habitually wrote multiple pages of feedback for them so they at least got something for their time if they didn't get a follow up interview.

Again, the purpose of the challenge was not a screen, so much as it was to help guide the in-person interview and so we had something concrete that we could discuss.

Follow up edit:
Designing code challenges is hard. You have to avoid something so objective it can be copy-pasted from stack overflow, but objective enough that it can be graded free from personal bias (as much as possible anyway). On top of that, you can't test for MVC+CQRS+FP+SOLID+every-other-possible-thing under the sun, because you have to be respectful of candidate's times.

The previous code challenge (the one I replaced) would frequently take people 8-20 hours to complete, and it was actually pretty simple. As you rightly pointed out though, candidates often read far more into the requirements than were actually there, and would often over-achieve in an effort to stand out. Not only would those submissions waste their time, it wasted ours as well as they took longer to develop feedback from.

Maybe that is a legitimate concern for flight attendants, but I totally reject there being any measurable impact on my hearing from riding in a 737 a few times a year. Particularly when I also do other activities like walking down sidewalks next to traffic, which is typically louder and very often MUCH louder (every time an emergency response vehicle drives by blaring a siren which incidentally incorporates white noise.)

Headphones and earplugs are uncomfortable when worn for several hours in a row, either because they are inside my ears, or because they are bulky. This is a matter of comfort, particularly since I try to pass time on planes by sleeping. A noisier commercial airliner, all else being equal, simply is more comfortable than a quiet one.

(I dare say sleep loss and jet lag have a more measurable impact on my health than whatever hearing loss is induced by a typical commercial airliner.)

Tech has also given us freedoms. It's just what people do with it. This world would be so easy if nobody was cheating or aggressing on anyone else. And it's not lile that because people are terrible. Most people in this world are immoral and/or idiotic. The average person is not enlightened, nor even genuinely motivated to helping their fellow if they gets nothing in return.

Now you are asking for not just good nature or enlightenment, but for something more... moral courage.

The sad part is the people who are will be lost forever as we march this ugly walk into the Grest Filters which consciousness seems to tend to do to itself.

The only way to get something like moral courage from the masses is to spread ideas into people's minds the same way religious leaders or propagandists do. People love crusaded and want to be important so will become a part of them.
Yes, that fits with my own experience. I've not used Typed Racket itself, but I've used contracts in untyped Racket. I found them so slow that I ended up using a macro which discarded them unless it was a run of the test suite.

Figure 3 in that paper is enlightening: the fully typed version takes 0.7x as long as the untyped version, so Typed Racket is slightly faster than normal Racket. Most of the partially-typed versions take 50x to 100x as long, as you say, showing that it is indeed the contracts that slow everything down.

As the saying goes, the markets can stay irrational longer than you can stay solvent. Even if someone can correctly predict a market crash, correctly timing it to make money is extremely difficult. You could go all in on far out of the money January 2020 puts only for the market to continue climbing and then crash hard in February 2020.
Somewhere there was a quote; Paying minimum wage is like saying: "I would like to pay you less, but it is illegal to do so."
They already agreed lots of copyright laws and the like, be kinda ironic to use those laws for civil justice.
But that's only one of the possible scenarios.

A different one is that employees leave Employer B for Employer A (or others). So Employer B makes more money per employee, but he has less of them now.

All those Walmart store managers make 6 figures as you say, some as much as $250k, but the one thing they can always fall back on is they all started out as a low paid Walmart employee as well.

It doesn’t change the inequality dynamics but it’s better than something like this story of the healthcare execs making $300k+ bonuses compared to their minimum wage coworkers, where the execs never started out making min wage with the company...or consider the horror story’s of those certain tech companies who don’t even treat low wage employees as regular workers and encourage regular high wage workers not to socialize with the low wage workers.

This seems like the equivalent of a man walking up to a homeless person, kneeling and handing the man $5 while his wife takes a picture of the action... Oh! You have an ounce of humanity left in your slowly freezing heart, you want a cookie jackass? Had the top 5% cut their salaries in half and disbursed it equally to the bottom 5% then I might have been impressed but anything short of that and you aren't going to get me to bat an eye.

I may eat some downvotes for this but I really need to say it. It's a bit off-topic, too.

Please, do not start believing you will be making a difference through charity.

I observed rich people in the past that out of some half-conscious guilt started thinking they need to give back in some way. But they don't want to be inconvenienced by doing it personally or by evaluating which people deserve a donation or have an important material problem solved, by themselves. They prefer to unload their guilt -- or the need to feel good about themselves -- through a 3rd party. Basically, buying goodwill and good conscience with money.

That's not giving back.

I have known several rich people and they go through a very similar process. It's very saddening to observe.

If you want to make a difference with money -- go out there. Physically! Meet people with less. Talk to them. Ask them what is the hardest thing in their lives at the moment. Ask them what's a regular concern for them. Do that 100 times, or 500 times. Understand their struggle. Many would just squander the money in a week, even if you gave them a bag of it. Try and aim your efforts and money where it will truly count.

It's not an easy thing to do. But it's a worthy cause to pursue, much more worthy that a random charity.

Apologies for off-topic.
I can never wrap my head around the thought process. Kill innocents and somebody else will be impressed with Anarchism somehow?
The 'cost' of labour is the income required for such labor to maintain itself.

I.e. living costs + healthcare costs + groceries & other expenses + a little saving.

This is the base cost of a person, and thus the base cost of labour.

These stories are so misleading. Up only means something in relation to when you bought. Everyone bought at different prices and some people are very "up" while others are decidedly down.

If I've learned anything about the stock market, it's that no one knows what it's going to do. The only good plan is to make sure that you're going to be able to stay afloat if the market tanks tomorrow.
I think TV has created an image where young people can get really aggressive or even physical with police, doctor/nurses etc. The receiving side of this aggression are quite understanding people who'd say 'oh this guy is just emotionally hurt and it should be fine'.
Had one with Deliveroo. They responded, but they were declining me because I didn't do what they explicitly told me not to do in the instructions. They wanted people who "went above and beyond".
In a propeller aircraft, basically you waste the energy left in your exhaust gas. But in a turbojet you make some use of it.

Also there is the distinction between just propeller, a turboprop, a turbojet and a turbofan. What we call jet airliners are typically high bypass turbofans. Turbojets (without bypass) have low efficiency at subsonic speeds, but they were used on Concorde and on fighter aircraft.
That was in 1999.
Hmm, it's not like they go "positive match, right bake 'em away toys". The officer will analyse the match and on their confirmation that match means there's reasonable cause to question you, ask for ID, or whatever.
It's extremely normal to travel without any kind of ID, especially photo id. The main thing a lot of people carry is their driver's license, but if you don't have one of those you might very legitimately have none.

Given some of the responses to the Reddit and Slashdot redesigns...
First place is home, second place is work, third place is communal areas - sometimes the media is referred to as a fourth place.

He's saying that homes are built/valued almost entirely with access to jobs in mind and not communal spaces, and that this has not been helped by zoning laws that enforce this problem, nor by a lack of political will to tackle either this issue or any other deep-seated causes of the problem - things like housing costs for instance, which is part of a wider issue of increasing wealth disparity across the US.

Or perhaps more succinctly, the problem is a focus on fixing the surface problems of an increasingly well-off minority, instead of trying to tackle the underlying structural problems so as to benefit everybody.
Agreed. It's funny seeing replies here. Making people feel bad about themselves doesn't get very far in influencing their viewpoints. A lot of smart people disagree with higher minimum wage. You won't reach them by saying stuff like "it just takes a basic high school diploma..." "you're out of touch..." But you will get padded-on-the-back by others holding your beliefs.
Foster and Partners masterplans major mixed-use development in Santa Clara
I have to admit I'd give a pretty Machievellian answer as well, on the assumption the question includes having to keep the position. In harsher political climes, you can't afford to put "building a strong society" on the top of your priority list. One of the ways strong societies become strong societies and stay strong societies is to make it possible to play a lot of politics as much less of a bloodsport, so things like "building a strong society" may reach as high as priority 4 or 5 for our politicians. It isn't perfect, but it's a lot better.

Of course, the fact that I wouldn't do any of this in real life is also why I'm never going to face this hypothetical.

I'm going to guess "Abdicate power as thoroughly and comprehensively as possible to whoever seems most likely to be next in line, so that nobody is ever tempted to come after me or mine, because I am not suited for such a role and I deeply know it" would probably not be considered a viable answer by the questioner....
Ask HN: What can I do to be become better at thinking like a hacker?
My experience, at least, has been hacker mentality and that "quickness" that comes in being able to absorb new ideas, paradigms and become productive is a facet of many things. In particular, I find people around me exposed to programming at young ages and who have built things (little computers, emulators, Haskell programming etc) seem to be better at adapting and doing. For those that didn't do that growing up, apart from writing lots of code and learning, are there any other ways of getting better? I, for example, have found DNB very useful. What other ways are you guys hacking your brain?

> you'll see plenty of ... burqas

No, you won’t. The burqa is extremely rare in Western Europe. This is pointed out whenever political parties propose a burqa ban: a country would be banning something that isn’t even a significant thing there. IIRC, the total number of burqa wearers in all of France, for example, does not exceed 300.

As for niqabs, you do see one from time to time, but they certainly aren’t common against the total Muslim population, and when you do, it may be that the wearers are visitors from e.g. the Gulf states and not locals.
I don't know about that, but you do have a fundamentally different view of software requirements for interview tasks than me.
I'm afraid many people are just terrible at empathy, and imagining how it is to live a life very different from their own. As they say, the greatest privilege of them all is the ignorance of how privileged you are.

Such a thing does not exist. It is the study of exchange between individuals, any model that brings down morality to 0 will not be useful, practical or a applicable.

I can't tell you how many times I've never even gotten the courtesy of a response after interviews...even though I've checked in with them to find out where they were in their process.

The other thing that gets me, is not listing what the expected pay is upfront (and whether or not it's remote) on the job posting. We all work for pay and we all have a pretty good idea of what income it takes to live in your current (and future) circumstances. If your pay is nowhere near that expected range, why should I waste your time and why should you waste my time?

I got hit up on StackOverflow to apply for a company. After looking at their job listing, it said (limited remote with approval), making it sound like you had to negotiate for remote work. This is what I responded with, "I currently work remotely and have no intentions on moving. I have a proven track history of performance and productivity working remotely for over 7 years and it's not something I'm willing to give up or negotiate. So I can save us a lot of time by being upfront with you about that."

I didn't apply and didn't receive a response...

> The above is why there is a full-court press to ban guns in the USA

Our military has become extremely proficient in combating guerilla warfare. You're fooling yourself if you think that armed insurrection could happen in this country without the support of our armed forces. A civil war seems plausible, but the reason people are getting sick of guns in this country is the frequency of terrorists shooting up schools: the people willing to take up arms are predominantly children with extremist, hateful ideologies.
Full-court press?

Do you also believe that Christians are being persecuted in America?

How convenient that the author neglects to mention that facial recognition systems have also been shown to be biased against people of color.

Kudos to SF. More surveillance doesn't mean less crime; it means less freedom.
It's also crazy to me that the whole framing is around providing money for investment when any stimulus to the end consumer is going to inevitably end up at the top (it's not like money flows many other directions in the long run in our current system).
If you ignore taxes and say a raise of +7.50 an hour for a working week comes to around $14500 extra a year

For budgeting, you take the hourly x 2080, so $15,600 before taxes. I've filled out one too many government SF-424 forms back in the day.

I was told, when I was a contractor, to use 1920 x bill rate, so I had a realistic idea of the yearly with 4 weeks off.

If you want privacy, then don’t post online.
To add to this, there hasn't been any expectation of privacy beyond a reasonable amount out in public, in most places, for the longest time. Whether you think this is morally correct or not, it has been the norm for quite some time so this can't suddenly be surprising.
Considering there is new development happening all the time, clearly there must be some funds leftover.
ML can be used as an unbiased random number generator, unlike humans.
This is what I don't understand about the hard-line 2A advocates. They're so concerned with being able to "defend against the government" if needed but guns are no longer the government's biggest source of power over the people. Data and surveillance are far more powerful in 2019 than any weapon.

Full disclosure: I'm a gun owner. But I'd swap the second amendment for a data privacy amendment in a heartbeat.
Because all politically profitable strategies at increases taxes for the rich are always about giving a benefit to the most politically powerful group: the middle class.

A society where the top 90% pitches in to help the 10% in distress is very different to the one where the middle 50% takes from the top 25%, and leaves some scraps to the bottom 25%.

SpareBlox: New way to safely store files
Gauging interest for a thing I'm building that is basically SeqBox + PAR + local torrent. Data is broken up into self-describing 4K chunks and striped across as many drives as are available. Each block is hashed to enable data rot scrubs and small groups of blocks include redundant data to enable reconstruction. Files names and hashes are also protected with redundant data and hashes are consulted before making new blocks, to prevent dupes. Drives that go offline are tracked as offline and only get marked as failed when they fail a scheduled scrub or get marked as such. Data gets rebuilt on the fly when some of it is offline but there is still enough to rebuild. Right now I have a working demo that does most of this and I'm polishing up to do everything and be stable enough to start public testing. If there is enough interest, I'll know to prioritize this over my other projects. Let me know what you think!

> Sure, but that's all make-believe

Not from the perspective of many (but not all) monks. I think you're having a theory of mind failure here.
Yeah, the bottom of the page there also says they don't proselytize.
Square did this to me many years ago. It was galling and unprofessional.
> In the last few years there's been moves to increase that, but even moving from full time (which not everyone gets) at $10/hr to, say, $14/hr... That's $28k? Loaded cost with taxes and stuff might be ... $35k? $40k? Maybe? That's still a far cry from "we can't afford to pay everyone $100k".

Sure, but that's the point. Should the manager not get $100K just because there is no way the employees could? What if that's what it takes to get a good manager?

And even at the numbers you're suggesting, multiplied by hundreds of employees, turns into millions of dollars a year. That's more than the store's entire profit. And it's also still above the threshold where it becomes profitable to automate many of those jobs.

> Sure, you can't, but that doesn't explicitly justify paying most people $9/h part time when they want full time (and the store has a need for full time staff, they just don't want to have to provide X benefits that come with full time).

But whose fault is that? Employers generally shouldn't provide any "benefits" -- they originally came about as a tax dodge at a time when non-monetary benefits weren't considered taxable income to the employee, and that's still the primary reason they exist. Company cars disappeared when they became taxable income, employer-provided health insurance didn't because it's still a tax deduction. But in every case the employees would be better off with the equivalent in cash and the only reason they don't have it is dumb laws.

It's even worse for low income employees because the rules keep trying to "help them" by giving employers huge incentives to cut their hours.
I've never seen this. Thanks!
