But if the value is determined by a single centralized entity, what is the value that crypto tokens bring?

For example, if WOW currency were to become decentralized overnight -- what would practically change? Either way Blizzard can take them away. Either way value of token will drop if Blizzard does this a lot.
Seems like a nice approach. I've been through similar setups and I think there are still tradeoffs though. Step #3 is tricky as you need a task complex enough for the candidate to show their skills, but it has to fit within a few hours. Unrelated to interviewing, I routinely under or overestimate task size, so carving out just the right task can be difficult. New features and bugs often have unknown unknowns.

The "contrived" puzzles approach has the advantage that each candidate can be given (and thus evaluated on) the same task. The size and perquisite knowledge for the task can be well controlled and since the problem is not new to the interviewers, we know how to present it in an easily understandable way and help them if they get stuck.

I think another reason why the "general cognitive ability" approaches are popular is because employees (especially at small companies) need to be good at such a wide range of tasks that it is not realistic to evaluate even a fraction of them in the span of a few hours.

I was curious why you would return a value and not just make the main function return void (in the interests of simplicity and maintainability, and assuming you're using C not C++). So I wrote my own such program, and discovered that void main(void) returns 3 to the OS. Any ideas why?
There's an element of Nissan Taleb's "Dictatorship of the Small Minority"[1] at work here.

If you bring together a random group of C++ programmers, some of them will approve of exceptions and some of them will see exceptions as an abomination. The former group will grudgingly write non-exceptional code; the latter group will not write exceptional code (at least in C++). Consequently, the codebase ends up banning exceptions, the fact of which the anti-exception people use as evidence for more exception bans in other projects.

This dynamic doesn't speak to the validity of the argument against exceptions. It just indicates that it's usually easiest, socially, to just appease the anti-exception people.

Ask HN: Points or hours for time tracking and estimation?
I've been meaning to try and get better at estimating my work, but I figured I'd start tracking to figure out exactly how long I take on things to begin with. I've been on the fence of whether to track by time or hours so figured I'd reach out to the community to see what people feel as a good pick now? Whether it be on a team, individual, or what have you. How do you track progress? What do you like or dislike? And what kind of software (or nontechnical system) do you help manage the data?
Many I'm in the minority but if I need one small item I'll write pure javascript if I need a little more I'll use jquery, if I need an spa I'll use react or vue if I need an site/app I'll use the ionic or quasar framework.

Use what you need.

On a side note, it's a legal requirement in some countries to having a working CO detector in the home, certainly for rented properties in the UK. Also in some (30+) states by the looks of it [1]. A $10 detector would have probably saved the gentleman's life.

A flat earth can also spin.
This would never happen in the UK or Norway as petrol costs too much and people just would not have a house big enough that they would not notice an automobile engine chugging away right next to them.

Cheap petrol in the USA means that people are in the habit of doing things like starting their car remotely to 'warm up' or 'cool down' before they then have a shower, brekkie and what not before finally getting in their car. Usually the car is on the driveway and not the garage in these scenarios, however, that is something that would not happen in the rest of the world, where petrol costs real money in part because a U.S. dollar has to be bought in order to buy the oil that is always priced in petro-dollars.

Given that people do suicide themselves by connecting some hosepipe from the exhaust to the interior of a car I am actually surprised that there are not rules regarding CO detectors already. CO can not just kill the occupants, you could have a big pile-up on a motorway due to CO poisoning. This happened a few times with police cars last year and 3/4 of all CO deaths are due to vehicles, not central heating or other sources.
I would bet that collectively the time wasted due to mishaps exceeds time saved by this feature. For me personally, I don’t think I will ever make the time up in my lifetime - I have accidentally killed a battery once because the car was in ACC mode and I didn’t realize it, and another time I drove away without the key because I was dropping the owner of the car off at the airport.

> On average, that's two deaths a year in a country of more than 260 million passenger vehicles.[1] These accidental deaths are tragic, but it's actually impressive how infrequently they occur.

The deaths and injuries are utterly avoidable with decent design. Also, this is a feature that isn't prominent yet. The number of deaths is only going to get higher until the cars are built to turn the engine off under the right conditions.

These problems are not as bad with an electric car like a Tesla. I have left AC on but the battery was fine. I have been dropped off while the driver had no key, and it posed a slight issue once they stopped the car and got off the seat. Obviously, no CO poisoning.

From Scheme to Dependent Types in 100 Lines
I had a pretty scary run in with CO from my car once and it had nothing to do with the keyless fob. My car with gasoline direct injection had two bad injectors fail while I was driving home. It went into limp mode. When I got home I inserted the OBD2 scanner to diagnose the issue in the garage. Because it was in limp mode, the engine was running rich and I guess producing a lot of CO in my garage. In the roughly 5 minutes it took me to start the car, get the code, and shut it off, it had produced a dangerous level of CO. I left the garage and went inside. About 30 minutes later while I was in bed my Nest smoke/CO detectors alerted me to CO in the hallway connecting my house to the garage. I ventilated the entire house and garage and the alarm stopped. I did get a light headache from the short exposure.

Moral of the story, never run a car inside the garage with the door closed and always have CO detectors throughout the house. Nest probably saved my life that night from my own mistake.

If we want a more general solution, we should look beyond the keyless fob and just make CO detectors a requirement. You don’t need fancy ones like Nest. Cheaper ones that cost 20 dollars still works.
Any of those you want to describe in detail? Reading Kurzweil’d actual books felt rather like finding out the emperor has no clothes, to me: he made a lot of false analogies, conflated massively different things so he could argue for exponential growth, and made predictions so vague that he resembled a fortune teller more than a technologist.

The validity of arguments for/against the singularity are distinct from whether Kurzweil is a bullshit artist, of course.
> which might even be useful for real work

In my experience, this is where the house of cards collapses. For most programming jobs, none of that will ever be useful. And on the rare occasion that it is, you'll have gotten by without needing it for so long that you'll have to look it up and more or less learn it again from scratch anyway.

I find these sorts of things to give far too little useful information during a developer interview.
Yeah, that's fair. I drive a manual car, which makes it very hard to absent-mindedly leave your car running (at least if you park it in gear, but I think most people do).
I wonder if it wouldn't be possible to have 'heisenberg exceptions': if an exception is caught, it's just a normal exception, but if it isn't caught then there is a core dump which means you get all the data you need to debug the issue.
Keyless cars are a tiny fraction of overall vehicles.

The net befit is also minimal, so if they became popular you would expect a ~hundred deaths per year for what? Do save 20$ per car because they lack CO detectors?
Exactly. The actual point of most advertising is to manipulate people into doing what the advertiser wants. Coca Cola doesn't spend billions on advertising because somebody out there isn't aware of Coke.

Even if I never fall for it, the stuff that's most "relevant" from the advertiser perspective is to me the stuff I have to do the most mental work to ignore. The more irrelevant it is, the less I notice it at all.
Possible? Trivially. Doable? Not really, because cost margins are tight on cars. Remember, you're talking about the industry that once viewed it as cheaper to pay out lawsuits than to fix a dangerous fuel tank.

There are certainly a large list of reasons a car should be automatically shutting off without the keys present, but I feel it's also important to put the article and the figures they use into perspective.

Check out the GM Ignition issues where the cars lose electrical power because the key ignition moves out of the "on" position. The owners own key ring adding additional weight increasing the chance of this happening. This literally created the opposite problem... Keyed ignitions causing accidents.

We are so used to vehicles that it's so easy to forget that they are large and heavy machines. Just driving the car to work every day puts you at risk.

The article reads like... complaining about the rain while a tornado is heading your way.

Anyhow. Don't get me wrong... getting out of your car with your keys should certainly make the car yell at you and then automatically shut itself off after a period of time. With the option for the user to manually turn these things off of course. (I am a firm believer that one should be allowed to shoot themselves in the foot if they explicitly go out of their way to make it possible). I am just a bit irritated at the article. :)

I learned to drive in a manual transmission truck made in 1987, with a clutch interlock. But I bought an '87 car with a manual transmission last year, and to my surprise, it doesn't have a clutch interlock. So I have inadvertently started it in gear once or twice.

As it happens, I also have a 2016 car with a manual transmission and it is keyless - I haven't had any problems with it.

> Because they believe that they have arrived at their beliefs scientifically, anyone who disputes their ludicrous conclusions must be irrational.

So they don't understand science at all but claim to use it. Typical. Singularitarians are a new version of scientologists which are a new version of mormons which are a new version of protestants or siekhs which are a new version of ... You get the point. Different details, same dumb stupidity and desire to control, use, and take advantage of others. It's just interesting to see such groups at different stages of their development and how the wider society around them responds. Typically there seems to be more acceptance as these religions get older, which is hardly surprising given humans' proclivity towards blind tradition following even when such blind following is dangerous. Humans have a hard time being skeptical of even the dumbest ideas if they are codified in tradition and this is something that such religions rely on to become established over time. Such religions usually survive in the long term if they can make it past a generation or a few decades and establish themselves as tradition, something singularitarianism is struggling heavily with currently. Fascinating to see how illogical ideas and systems of control like these religions come about.

For example "irrevocability of transactions" is fixable by introducing arbitrators. This has the huge benefit of making the trade off explicit and still allowing for irrevocable transactions. With 2-of-3 multi-sig escrow services can be implemented in a decentralized and trust less way (if both parties agree no escrow agent has to be involved).

Handling private keys has also become much simpler in the past years due to hardware wallets and hierarchical deterministic keys. But I can see why someone could not want to be responsible for the safekeeping of their savings.
This was my problem when I rented a keyless car for the first time last year. To preface, it was a v6 mustang which I wasn't actually expecting to be quiet, but in comparison to what I'm used to it was practically silent.

Consider that cars have three usual running states: off, electrics on/engine off, everything on. How do you tell, quickly and conveniently, which state the car is in? With a key you can reach under the wheel and verify what state the car's in, in under a second. I haven't seen a keyless car system that was anywhere near that intuitive. Engine noise is usually the best indicator but as you've mentioned, cars are quiet now.

With the rental car it took me a good half hour to figure out all the nuances of the keyless ignition. Compare that to seconds, occasionally minutes, of getting used to "normal" cars with keys/fobs.
I actually think that the “singularity” in the broad sense that there will come a time in the next century or so where technology will develop too fast for human beings to keep up with it without radical changes to our way of life is almost a foregone conclusion, I don’t see how you can look at the past century and not think there will be radical changes ahead of us. It’s the idea that these changes will be necessarily positive, or that they will lead to the benefits that Kurzweil et al so desperately want, that is largely wishful thinking. The future will be beautiful and horrible in equal measure, and expect that while some things will get better, some things will get much, much worse.
>A $10 detector would have probably saved the gentleman's life.

True, but making the Federal Motor Vehicle Safety Standards requiring the $5 sensor in that $10 detector in every vehicle equipped with keyless start (or perhaps, every vehicle) would lead to nearly 100% deployment as the vehicle fleet is replaced.

By comparison, despite decades of passing laws and funding public education campaigns, only 33% of households ("occupied units") having a working CO detectors[1], and 40% of "working" detectors failed to alarm in hazardous levels[2]. So overall, just 20% of households have adequate CO protection.

FTA:

> From news reports, lawsuits, police and fire records and incidents tracked by advocacy groups, The Times has identified 28 deaths and 45 injuries since 2006, but the figures could be higher.

Let's estimate they found 1/3 of all cases, for a total of 56 deaths and 135 injuries. Estimating $6m per statistical life and $3m per injury (some injuries, like brain injuries, can be more than $6m for lifetime medical care and lost productivity, but this estimate is intentionally conservative). That's $61.75m annually, compared to the average of 13,532,750 annual vehicles sold in that time period[3], so about $4.5 of harm reduced per vehicle.

So economically it seems like a wash, and it prevents awful tragedies. Sounds like a good idea to me.
