A civilization-ending meteor will probably never head toward the earth, but your ethical worldmodel should be able to handle this scenario without special exceptions, rather than just try to assure yourself that it can't happen so you don't have to think about it.
The idea that you cede the moral high ground when you use torture seems to have been forgotten.

I don't care if it works. I grew up believing that we were "The Good Guys" and under no circumstance is it ever acceptable for the good guys to torture people.

What made the Viet Cong so bad? They tortured people.
What made the Japanese so bad? They tortured people.
What made the Germans so bad? They tortured people.

We should never torture anyone.

Also, it is just Forbes' words that Didi "emulate Uber’s model whole cloth". Fortune has a different perspective "But Didi has some built-in competitive advantages, by virtue of the fact that it was in the market earlier and that it designed its business for the Chinese market, instead of trying to import a template perfected elsewhere." http://fortune.com/2015/09/30/will-china-be-ubers-waterloo/

The Fortune article gave more details about Didi's model.
Probably not much, but it's a silly comparison since newspaper classifieds do not work the same way: It surely helps that the newspaper is not managing the inventory, payment processing, photography, and customer relations on behalf of their sellers.

I think it's sufficient to love doing a good job, i.e., to take pride in your work. I doubt my dentist's staff is passionate about removing tartar from teeth, but I would guess they enjoy doing the work correctly.

And even if you're doing what you love, you won't necessarily love every moment. Nothing has the potential to rob something of its enjoyability quite like a bad boss or soulless company.

Further, "passion" isn't really applicable to wide swaths of jobs. And many people's passions have no chance to be profitable.

I think more practical advice is to do work that makes you happy.
Try to find a small, diesel pickup-truck in the USA. Before cars like the Fiat 500 hit our shores, I doubt we had any very small-engined (<1.5L), while Europe had many, some of them even being diesel.

I was a car enthusiast for a fews years, and you quickly notice that Europe has a MUCH better selection of very fuel-efficient vehicles. In the US, well... we popularized the muscle-car and the Escalade.
This is the whole point of the movie the Great Escape. The allied prisoners know they won't be tortured since they're in a Luftwaffe camp and not a Gestapo one. After the escape, the ones who are recaptured are handed over to the Gestapo and are executed. Even in a 1963 film set in a Nazi POW camp, it was understood that there were rules. Sic transit.

Good question :)

I needed a quick way to hack the output of 2D float data (pixel annotations to complement some image) into some legacy C without adding dependencies.

Thanks to CImg, I can read and display the PFM files in 10 lines of my own C++. I thought about just writing a width/height-annotated binary blob instead, but then realized that's really what PFM already is.

I have no idea if anything is really using PFM. I certainly have not found any "big" compatible programs.
Another interesting feature of dividing by 7 is that the decimal repeats as:

0.142857 = 1/7
0.285714 = 2/7
0.428571 = 3/7
0.571428 = 4/7
0.714285 = 5/7
0.857142 = 6/7

you can see the first digit after the decimal point increases in numerical order through the available numbers in the pattern, the proceeds to repeat in the same order

Some other prime denominators behave the same way. For example, 1/17th is 0.0588235294117647 and the first digit after the decimal point increases like 0,1,1,2,2,3,4,4,5,5,6,7,7,8,8,9 ... Where there are 2 of the same number in the sequence, the first time you encounter that number you start from it's first ocurrence so for example 3/17 is 0.2941176470588235

This makes for a pretty spooky party trick but I can tell you from experience it doesn't attract the opposite sex.
But the precise identity of these substances
is often unknown to researchers and printer
users because the printer manufacturers don’t
disclose this information.

That's not entirely honest. That statement conflates the idea that there is no information available to end users, detailing how 3D printing technology works, when the truth is that the information is out there, and most of the materials involved in consumer-grade plastic 3D printing kind of HAVE TO BE well-understood from a chemical perspective in order for the printers to be designed around them.

FormLabs does publish material safety data sheets:

http://cdn.shopify.com/s/files/1/0183/2285/files/MSDS_v7.pdf

So does Stratsys:

http://m.stratasys.com/ig8del/lnk000/=usglobalimages.stratas...

The larger companies DEFINITELY force you into using THEIR proprietary plastics, when open-source printers permit the use of commodity ABS or PLA.

ABS - https://en.wikipedia.org/wiki/Acrylonitrile_butadiene_styren...

PLA - https://en.m.wikipedia.org/wiki/Polylactic_acid

But, realistically speaking, just based on the fact that it's possible to cobble together open-source 3D printers from commodity parts and commodity expendable plastic, should inform the reader that the materials used by 3D printers are not so mysterious. In most cases the materials are acrylic/styrene based polymers, and not so exotic that they haven't been used for decades. Whether they've EVER been safe is another question altogether.

The article neglects and glosses over these details.
Uber drivers get paid an amount based on a subsidy multiplier of the ride value, and they are highly sensitive to these multipliers. According to a driver I talked with recently, Uber takes 20% of the fare, but is currently giving drivers a bonus of about 2.5x. So if a fare is 10 rmb, Uber takes 2 rmb, then pays out 8 * 2.5 = 20rmb. Driving costs these drivers roughly 1-2 rmb/km, and if the subsidy ever fell below 1.3x, the drivers would lose money (these are for People's Uber level of cars, which is the lowest level). Unless the subsidy can ever drop below 1.25x, Uber will be paying for every ride. And if it does, drivers will be parking their cars or switching to another service.

Uber also lost a lot of money through a couple of vulnerabilities that have since been, I believe, patched. Some people were able to figure a way to create fake rides through the app, allowing drivers to get paid without ever driving anyone. They previously also allowed riders to link up Alipay accounts to their Uber accounts, but Uber had no way to ensure the Alipay accounts had funds. So people would take Uber with an empty account, and Uber would have to pay drivers without receiving any money from the riders.

Another side note: there was recently a publicity campaign with some well-known celebrities that had very explicit nationalistic messages encouraging Chinese citizens to use their local service and not the services of an outsider.

Uber will be burning a lot of money in China.

Not necessarily; you could torture someone for something like a key to an encrypted file. This is something difficult to guess, but easy to verify the correctness of. I am not saying that torture is justified in this scenario, but only that it is not true that "to verify outside of checking is to continue torturing which defeats the reasons for the person surrendering the information in the first place".
First to market in the US. This Fortune article http://fortune.com/2015/09/30/will-china-be-ubers-waterloo/ says Didi was in the market earlier in China.

Any thoughts on lowRISC?

http://www.lowrisc.org/
For an interesting example of that, check out Antoine Lavoisier https://en.wikipedia.org/wiki/Antoine_Lavoisier, executed during the French revolution.
If the argument is that _everything_ is inherently caveat emptor and that in many jurisdictions there are no / inefficient regulations and yet people seem to get along "fine" then why regulate anything at all? Open slather! Everything's "at your own risk".

If so, we should all get used to conducting our own safety tests on everything we buy and everywhere we stay? Although, that would be pretty damn inconvenient, wouldn't it? Day-in, day-out, inspecting everywhere we stay, every vehicle we ride in, all the food we eat... and the restaurants we eat them in...

Maybe there's a solution. Perhaps we could hire people to do those inspections for us, and since those inspections would inform everyone, we can communally pay for it with taxes? These people would certify whether something was safe, and ensure everything that was for sale / rent was certified to meet some minimum standard (because of course, otherwise some unscrupulous people might be inclined to lie about being certified.)

Problem solved! I'm a genius. Oh, wait a minute...

I think criminals need to be prosecuted (e.g. the atrociously blatant Bleen project: https://www.indiegogo.com/projects/bleen-3d-without-glasses#...). Nay, I think criminals need to have their hands cut off in town square.

But incompetence is a risk when you throw money into a Kickstarter/Indiegogo-shaped hole that smells like interesting technology. If it's obsequious and insidious incompetence, lump them in with the hand-less criminals. If they gave it a good long try, had consistent updates, release project IP and open source software, well... That's what we're here for. To try and get ideas off the ground. You're going to lose money at some point in the process. I regularly throw money into all kinds of electronics-shaped holes on Kickstarter and Indiegogo. It happens when the stars don't align that I lose my money. But if they aren't criminals about it, well, shit happens.
> If further exposure to UV reduces toxicity, the 3D printing process isn't finishing the curing process.

Then that seems super solvable. There just needs to be an end curing phase added where the final object is exposed to UV for a little while.

No not all countries. Australia for example has no fuel emission standards. It's really only the EU that has been so far out front in this area.

Tesla is just clutching at straws here.
What you've said sounds like a reasonable argument why torture doesn't work in that case. My point wasn't that torture does work (I have no idea about that), just that the research outlined by O'Mara doesn't address situations like this (and so the research isn't enough to prove that "torture is ineffective" as is suggested).
Arsenic, cadmium, lead, polyvinyl fluoride, and probably more. There are indeed liquid based solar panels. The toxicity of solar panels both in their production and their usage has been reported on a great deal. Some companies are making changes to make them safer but I have no clue how far along those efforts are.

Solar farms are hurting the ecosystem when they break and leak out. Even if they aren't liquid based, solid state versions have thin films which contain some chemicals like cadmium and arsenic. Cadmium telluride has been introduced more recently has it is safer.
Weren't there even tax cuts provided to those who bought big SUVs?
Graphite is ugly. Graphite is hard to use beyond just clicking a few graphs. Graphite requires some hard work to extend. But I am still using Graphite because

1) it is simple to set up!

2) nice to have a fixed-size flat file as database, although performance degrades very quickly. Cache misses is too frequent.

3) over raw socket is also quite attractive

No other solution can compete with Graphite for its simplicity. But there is so much more than just sending data to graphite from collectd, or your custom Python program....

I don't think I've ever worked on a project that deserialized untrusted Java objects; where does this come up?

I suppose -- if you have a Java client for a (probably) EJB-based server; most of the cases where I imagine this sort of setup are with internal-only solutions, though, which mitigates the risk somewhat (but obv. it would still need to be corrected).

I've read about banks in some countries still commonly using Java applets for site access -- that could be a seriously-dangerous attack vector.

I agree, we can not trust Tesla or Musk any more than Toyota. I find Tesla Model S pretty third rate and over-hyped car and I find it despicable that rich people get $10K subsidy on each Tesla they buy while a lot of us drive 20 year old cars.

Keeping the motives aside I am unable to see how auto industry benefits by keeping fuel efficiency standards low. Fuel efficiency standards are more affected by competition than government regulation. However if government somehow sets unreasonable and achievable standards while keeping the cost of car low, losers such as Telsa might benefit.

The more important question to ask is whether American air is more cleaner than other parts of the world. Having traveled a bit I can say it is. Also comparison to any European country is completely meaningless, USA is a large country where people drive all sort of crazy vehicles for crazy purposes.

Way more likely that no inspection has ever been carried out.

But the freak-nature of this accident still stands. 100,000 people could go find their nearest (un-inspected) tire swing right now and have at it.

It seems to me that the author just don't feel comfortable with MWI. He feels threatened by it, in the same way people didn't feel comfortable with Copernic, and just decide that it has not to be right. Doesn't look like a good basis for doing science.

In David Deutsch's "The fabric of reality" there is a good philosophic defense of many worlds. At some point he says something along the lines of: "if in the double-slit experiment photons are interfering with ghost-photons, what it means to say that those particles doesn't exist 'in reality'? "

Part of the reason you get so many differences in opinion for these kinds of questions is it depends on the type of work and environment.

For example there are thousands of HN users who work in companies with <20 people. I personally have more than 5x that number of people on my floor.

There are companies where anything not directly work related is discouraged and then there are companies where having a 20min coffee break with co-workers, or having weekly team events, etc is encouraged. In the first kind of company it would be isolating to work in a private office, whereas in the second kind of company it could work well.

Etc, etc. Personally I hate open offices... but I work next to sales people and a few very loud co-workers.

I think this is a very one sided view of things (its NYTimes after all).

The purpose of arbitration is not to take away customer's right to seek justice. The purpose is to reduce costs of fighting a lawsuit in court which is far too expensive.

I do see the risk that arbitrators might favor the right of company more than the customer but such a company and arbitrator eventually lose credibility and market share.

Imagine we had to outlaw the whole arbitration process, what would happen that ? Courts will have more cases to address and both involved parties end up spending more money than usual which increases the cost of business for everyone.

I would rather opt in for arbitration and get my car for $500 less than see the arbitration process go away.

There probably are a few assholes who don't, but to take it seriously outside the realm of a purely philosophical discussion on formal logic is something that no sane human being should even consider.
