The difference between old school billionaires/big industrialists is PR.

In the old days, it was less of a science and was all about "big". Milk Bone dog biscuit ads 100 years ago featured a big picture of the factory.

Now, it's all about a carefully crafted image. There's a team of people making sure that only that crafted image, which is boring, appears in public. Some people like Elon Musk or Richard Branson are all about the personal brand show/cult of personality. Most people wouldn't recognize Sergey Brin.

>When the brain is damaged or undergoes chemical changes, we know that consciousness seems to disappear. There is no strong evidence to think this is different upon the death of any organism.

People often have dreams under such circumstances, and there are many who have died and been resusitated that report having wild experiences inbetween.

>we fear our eternal end WHILE we are alive

Again, you're mythologizing/hypothesizing here with your use of the word "eternal".

But yes, when confronted with immediate life threatening situations, all animals including humans have a natural fight or flight instinct. However, not all humans (and seemingly no animals) have such existential dread like you do of a future of eternal nonexistence. Your fear is a result of your materialist reductionist mythology.

The simple fact of this discussion is: no one knows what death is truly like, so we can only extrapolate, hypothesize, and mythologize.

Personally I think it is in everyone's interest to try it at least once.

Of course people are depressed. Most people's lives are about work that is not enjoyable, in order to get money to live somewhere.

I think it would be super weird if most people were happy. I don't mean us, the IT crowd, with tons of money and a job we mostly enjoy. We are living luxary lives, most of us.

But the others, with low paying jobs, they have no interest in? Of course a lot of them are depressed. It's a consequence of our societies and how we live.

5 yrs ago (mostly for fun) I tried out the 'state-of-the-art' - at the time - NLTK sentiment analyzer to correlate stock market changes with a variety of news/info sources.

I put it on the shelf because the sentiment analysis just wasn't up to snuf (i.e. the bias differentiation was too weak).

Might be time to try again!
Ask HN: How to build a offline first app with mysql as back end database?
We trying to build a mobile (android only) app and python3 pyqt5 based desktop app with a php mysql/mariadb based backend hosted on a low end shared host. Mobile and desktop clients with a php web based admin panel on web. We want our mobile and desktop clients to offline capable and sync their data once they have internet connectivity with the central mysql/mariadb database which is adminestered from the php web based admin panel. We are on low budget, cannot afford a dedicated server as it is a community (blood doners) communication app. Please, guide us.
Race is often shorthand for ethnicity, and it's true that to a certain extent different ethnic groups have genetic differences of medical relevance. While variation within groups is generally larger than that between groups, that doesn't mean ethnicity is medically useless as data point. Classic examples are among those the OP listed. The most visible are probably lactose tolerance (significantly more common in Europe and cattle-herding populations) and alcohol dehydrogenase (also know as Alcohol Flush Reaction). There are many others and we're likely to find many more.

Medically important genetic differences between ethnicities exist, but it's important to note the limits of this analysis. Usually these are fairly low-level traits, i.e. different enzyme activity, and it's critical not not over-extend the logic to more complex emergent traits such as intelligence or others where clean biochemical links are suspect. Saying a certain set of constraints changed the way certain enzymes work in a given population is not the same as saying this group is better than another group.

I like this. At University of Florida we had 1 class. It was...alright, better than none. Everyone graduating through the college of engineering had to take it. But to have it mentioned in every single class and the relevance would be better!

Someone earlier in this thread is confusing "professional" and "engineer".
In addition, I think it's much easier to go back into the field and examine a bridge to ensure that something important was constructed to the specifications that you required. This is not the case with most of the software people write, certainly in this case it's pretty difficult for a developer to pull a car of the production line and verify that the code they wrote made it into the car without any changes.

I was considering ASM's for it:

http://pages.di.unipi.it/boerger/Papers/Methodology/BcsFacs0...

My thinking was like this. The complexity of software is synonmyous with us saying we don't know what it will do on given inputs. As complexity goes up, it gets more unpredictable. That's because of the input ranges, branching, feedback loops, etc. So, a decent measure of complexity might be simplifying all that down to purest form that we can still measure.

The ASM's are a fundamental model of computation basically representing states, transitions, and conditionals making them happen. So, those numbers for individual ASM's and combinations of them might be good indicator of complexity of an algorithm. And note that they can do imperative and functional programming.

What you think of that idea?
Bose allegedly collected and shared listening habits of its customers, too.

True.

The problem is always, how to get enough correctness that your customers are happy, but don't spent too much time on it so that rivals won't overtake you.
Ethics/Implication question: How much time is left until video/photographic evidence ceases to be a reliable factor in courts? I know that while projects like this are happening, so are projects that work to identify fakes. If the former manages to outpace the latter, this could become a real problem. My mind tends to think of a dystopian extension of cops planting drugs on suspects, where they could literally invent photographic evidence.

Hi,

We’re building a tool to help automate and optimise data science work to help data science teams become more productive. Given your expertise, I would love to get your thoughts so we build something useful.

Please let me know if you can spare 10 minutes to help a fellow HN-we out.

Thanks in advance
Ethics has its own vocabulary, history, and arguments in ethics are common and often don't have a resolution other than compromise. It's predicated on making logical arguments and has ties to epistemology: how do we know what we know?

So saying you don't understand the point of ethics classes, as if people are ethical or are unethical, is like saying you don't understand the point of teaching logic or debate as if people either pop out of childhood with an innate conformance or resistance to one kind of logic or debate, no other kinds exist and there are no arguments.

If you took an ethics class and don't understand the point of it, then I'd argue it wasn't a good ethics class.

> "the majority of hiring managers say they make no distinction between bootcamp vs. college graduates"

Since the industry norm is "You're all equally worthless until proven otherwise" I don't find it all that surprising. They'll take in your resume and toss you into the pipeline / grinder and if make it through the crucible unscathed, well, congrats you'll get a job offer!

Being neither a college nor a bootcamp graduate, I've found very few places give a damn what you've got framed on your wall at home. What matters is if you can hack it in the real world. The only time I've been turned away for lack of credential was Booz Allen Hamilton, and they exist to arbitrage you to the government which still seems to care about proper documents.

> considering that the article goes to say that "48 percent have not filled any positions with a bootcamp graduate"...

Well, that would mean 52% surveyed have hired a bootcamp graduate which is pretty surprising to me, personally, since the camp(s) in my metro seem to produce about two good candidates per cycle.
GP didn't say that law is not a profession, but rather that computer programming is not a profession. This is obviously the case, since there are neither educational requirements nor state-approved certifications for this work. There are ethical expectations, only because all humans have ethical expectations.

IANAL but one could certainly imagine 1A challenges to any attempt to enlist the state in the enforcement of a cartel like that of the lawyers or the physicians. In that sense it's no more likely that programming would ever become a profession than e.g. that writing would become a profession.
> For instance my Australian shepherd might not be able to bring me the newspaper; but if I really wanted her to do that task, I could slowly get her to approximate that behavior, and it would probably be satisfying to see progress in performance.

Given she's an Australian shepherd, it would probably be only a bit startling to subsequently come home and see her analyzing the finance section of the paper. :)

This is, I think, one of the failings of human ToM. We tend to underestimate entities which are different from us. The differences are not only of capacity and of information. They are differences of worldview, values, and biases that are very hard to capture, even between adult humans of different cultures. It's easy to imagine people as a less intelligent and less experienced versions of yourself, but that is not an accurate theory of their mind.

The same differences, only more so, are present between humans and dogs or humans and Siri. Given that the most empathetic and social people (with, I assume, a better theory of mind) are generally not found in technical roles, I wonder if they might find it easier to make that stretch and effectively use Siri or Alexa?
Indeed - for example, you can make things look simple by leaving necessary parts out.

I think, however, that the more important part of this quote are the words 'problem' and 'solution'. Until you have an understanding of the problem that is correct, it is unlikely that you will come to a solution at all. Avoiding the introduction of gratuitous complexity is not necessary to reaching that understanding, but it sure helps.

More generally: when you detach the consequences from the causes, everybody misbehaves.

We will see. Been "workating" with my family in LA for a few weeks and we ended up using Bird much more especially because it looks like Lime require you to pay in bundles (10usd) and there are just way more Birds available than Limes. It might change now that Uber is involved but they would have to increase their scooters fleet quite a lot I think.

Been interesting because in New York Bird isn't something people talk about where as here it was everywhere (didn't hurt we lived at Venice beach either).

One thing I realized is how much the ability to just leave your bird/lime anywhere and just pick it up where it is, affects your desire to use it.

We will see the same uptick in bicycles in NY I think once you are not required to park them at specific places.

It's a little bit of a mess though especially down on the beach promenae but I think there are plenty of ways to encourage good behavior.
I'm sure there is a practical reason why companies do this, but it drives me crazy and makes me want to ignore what could potentially be a really cool idea. Please make the pricing transparent and viewable without a registration.

"A program that produces incorrect results twice as fast is infinitely slower."

Well, I didn't mean to be an elitist. My point was that ethics is an important "skill" for engineers and you can train this skill by other means such as reading books. There are tons of books about theoretical ethics, scientific ethics, engineering ethics, bioethics etc. Even reading something as basic as Stallman can be very helpful for software engineers. I'm just pointing out that engineers should think more about ethics.

My turn to be a skeptic, looking for a response :)

We already have barcodes to track the source, this is already done outside blockchain.

Maybe its more immediate after a problem happens, but what is the cost to:

>Blockchain soil ph

>Blockchain fertilizer

>Blockchain water schedule

>Blockchain that workers washed their hands

>Blockchain the weight of the product

>Blockchain the date picked, shipped, etc........

If you do every step along the way, the cost becomes enormous. I cant imagine the size of the hash either.

Not to mention the extreme problem of garbage in garbage out. Sure you have an expensive thermometer that writes to a blockchain, but what about when its time to weigh it? What if someone accidentally sweat and that drip added 1g to the weight of something that needs precision.

Then the entire chain becomes unreliable.
However, modern sat-solvers do both. That is, although they are called "sat-solvers", they can actually output both "sat" and "unsat". In software verification they are used for the "unsat" side: you produce a logical formula P stating that your software is correct, and then you ask the sat-solver about ¬P. Hopefully it returns "unsat", meaning that it has proved P is true; otherwise it will return a satisfying assignment, which is a counterexample to your proposed theorem.

So I guess you could say that a theorem prover for propositional logic, like Logic Theorist, is "half" of a modern solver like Z3, it can produce proofs but not counterexamples. :)

"A very fast, simple solution that is 2% correct is an unacceptable balance."

That begs the question (in the original sense) of "unacceptable". If I banged out that 2% solution in an hour, and it lacked other costs that outweighed the benefits, it may still be something we ship! It is unlikely that we'd stop there, just because the numbers as you've given are unlikely to favor it because something else substantial would have to overcome the small amount of the problem we've solved, but to be firmly confident it's "unacceptable" you'd have to define "acceptable" a lot more carefully.

I understand the deep temptation to turn to discussions of the virtues of letting bugs through or something, but the costs/benefits framework completely handles that already. If you ship a buggy piece of "incorrect" shit, well, you've incurred a ton of costs with no benefits. That's wrong, by whatever standards you are measuring costs and benefits by. There isn't a "what if your 98% solution actually has a massive bug in it because you were unconcerned about 'correctness'?" argument to be made, because if it does have a massive bug, it's not a 98% solution.
I recently got a better bicycle and it got easier and faster. Well lubricated bottom brackets and a new chain makes a massive difference in speed / resistance.
Yes, I understand why atheists are so fearful of death, but also see the illogical and impractical nature of it.

>death for atheists is the loss of everything

Atheist logic should lead to the realization that from an individual standpoint, there is no possibility for the experience of this feared loss, at all. Immediately before the moment of death, you still have it all. Immediately at the moment of death, you have no conscious ability to experience the loss. Therefore the fear is not logical, it's irrational because your "total loss" is something you can never experience.

https://weakdh.org/imperfect-forward-secrecy-ccs15.pdf

Basically, for about $100M per prime (probs cheaper now), you can pre compute a big table that you can use to decrypt the diffie hellman exchange. From there you have the negotiated private keys, and you're off to the races for a full, real time decrypt. Since before the Snowden leaks, there wasn't the public thought that the choice of primes for diffie hellman mattered really for it's security, most implementations hardcoded the prime. Something like 92% of the top 1 million https sites were using the same 2 primes, and similar numbers of VPN and SSH implementations were vulnerable too.

So for a one time cost of ~$200m the NSA was able to decrypt the vast majority of internet traffic as long as they caught the diffie hellman exchange at the beginning.
Considering that, in recent years, cars got larger, more powerful, have better mileage, and pollute less: I think the regulations are extremely realistic.

I often repurpose a famous quote from Mark Twain (about letter writing) for the topic of simplicity:

> I didn't have time to write a simple program, so I wrote a complicated program instead.

This is in my experience more than just a clever turn of phrase: the vast majority of software projects (or features etc.) move from _simplistic_ to complicated, and rarely from there toward simplicity. The end result is exactly what this author describes -- a complex mess that's difficult to reason about and rarely performant.

Few of us (usually myself included) are willing to devote the time and effort required to achieve true simplicity.
Not talking about politics here isn't the same thing as saying that this community should not talk politics.

But I also don't think anybody wants to spend all day dealing with doom and gloom and arguing about inane partisan bullshit. It would be nice to have some place as a refuge from that crap, where we can talk about "cool tech" and not have to deal with all the other stuff in that moment.

This isn't true for the SL500 at all, and I would venture to say not for performance cars in general. The SL500 is a pig at nearly 4,000lbs and has way too much torque and horsepower, and as a result, oversized parts which aren't made for normal driving. As the "performance" of the car ramps up, so does the difficulty of handling the car. A possible exception to this rule is AWD cars.

I would say the U.S. has become blase about corporations not having a social benefit component. They can do really vile things, far worse than a human, and get off with a fine that may or may not be meaningful in inhibiting such behavior in the future. I can't think of a single historical case, which I think would be notable, of a state rescinding the articles of incorporation of a company thereby destroying its shareholders - the corporate equivalent of capital punishment.

Some states do have "social benefit" corporations as a thing, where their charter expressly states how they are to benefit society not merely make profit. But no state makes this kind of incorporation mandatory.
