I guess the tldr to your response is: "I'm actually doing nothing."
A lot of people get this idea of "poison, therefore avoid at all costs" in their head about a lot of things. For instance, my local makerspace does a "teach people to solder" table at public events to get folks into making things. So many parents upon learning that solder has lead, decide to take their kids away, because lead will probably kill them right now. Several times they have tried to get us shut down because we have lead.

It doesn't make it ok, just how some people seem to think.

Why do I keep seeing Heartbleed and Shellshock mentioned in articles specifically about Linux security? Those two vulnerabilities had nothing to do with Linux.

Software using OpenSSL or bash on any platform were vulnerable. That includes Macs and Windows.

Linux is extremely popular for servers and embedded systems where OpenSSL and bash are common but bringing them up every time "security + Linux" are discussed is a bit like talking about tires that blow out whenever the topic of logistics comes up.
All anonymity is not created equal: you're better off if we can only figure out that one out of 6 billion people bought a Nickelback album, then if we know it was either you or one guy in Tristan da Cunha. The size of you're anonymity set matters and Cryptonote provides a rather small one in comparison to Zerocash. This is not to say Cryptonote is worthless, there are tradeoffs between the two, but Zerocash has a distinct advantage in terms of anonymity and I think it matters.

Cryptonote's ring signatures scale linearly in the number of people your transactions are mixed with. As a result, you can't mix an individual transaction with that many people without it getting too big and too computationally costly(chaining transactions doesn't solve this). In contrast, Zerocash mixes every transaction with every other transaction ever[1].

If you are worried about maintaining privacy given repeated interactions with merchants or others who already have some partial information about you, the size of the anonymity set matters considerably. Longterm intersectional attacks are a major problem with anonymity systems. The smaller the set you mix with on any given transaction, the easier it is for some third party to use outside information to eliminate everyone else in the mixing set (e.g because she knows no one else in the set was online at the time of the transaction or was in your approximate geographic area), and determine the true spender. One of the few effective defenses we have for this is to simply include as many people as possible in the anonymity set. If you want to avoid companies building financial profiles of users from the blockchain, this is precisely the type of attack you need to thwart.

[1] Technically, up to 2^64 transactions and the networks ability to handle the spent serial number list. So there is a limit, but it's rather large.
That is arguably (by at least one Johns Hopkins professor [1]) a purely psychological response. Anything can become psychologically addictive with habitual use, but that doesn't make it a substantively addictive substance. You could practically equate it to "porn addiction" in that sense.

I up-voted you because it's a fair question, but the grand-parent is absolutely right: there are plenty of cases where opioids are marginally effective. The management of chronic pain in particular is problematic because opioid tolerance can develop in as little as two weeks. In addition, some people have paradoxical reactions to opioids, i.e. increased pain (http://www.ncbi.nlm.nih.gov/pubmed/21412369). Finally, the side effects of high-dose opioids are no joke.

The Soviets liked to do this sort of thing too. They'd have a groups of bombers fly past during demonstrations. Except instead of many groups of bombers, it was one group of bombers that would fly off, make a circle out of sight, then make another flyby.

This let the US to greatly overestimate Soviet production, and produce huge numbers of their own weapons to "match" the Soviets. So it all sort of backfired on the Soviets, since they mostly just convinced the other side to put their much greater productive capacity to use.

It is not just headphones that are the problem, it is the speakers.

People today are often amazed when they listen to CD or turntable content through 70's era crossover speakers. Back in the 70's you'd have a stereo with 2 "speakers" that each had 3 subspeakers for a total of six speakers. The fad today is to have 5.1 sound with a single driver in each satellite, also a total of six speakers. The spatial resolution increase is good for movies, games and TV but surround sound in music is marginal. An amazing number of old "classic rock" recordings were done in quad and anything by Donald Fagan will sound pretty good w/ Dolby Pro Logic, there are some more recent Bjork recordings, but almost everything is mixed for stereo and what you loose in frequency response is not compensated by anything, except perhaps the ability to produce more volume with more speakers.
I'm truly curious how having good isolation would help your hearing? Is the room noise a large additive?
It should also be noted that there was not one "Tank" SN used, as each component had its own set of serial numbers to be analyzed. In this specific example they used gearbox SN's along with chassis and engine SN to provide the estimate.

These statistical estimations were cross-checked with a broad range of other sources, in an attempt to gather data on everything from the number of tanks produced, to the number of factories in use and a variety of supply chain factors.
Intermodulation creates both sum and difference frequencies, the latter can certainly fall into the audible spectrum, assuming the ultrasonic frequencies are within the passband of your recording medium. The sum component can also alias back into the passband as well...

> Given the choice between a cheaper flight that's less comfortable, or one that's $5 more and has more room, people will choose the former.

This is interesting, I travel on a lot of different airlines, and I always go with the lowest-priced feasible option. However, I don't really see it as much of a choice between quality and price.

Why? Because I don't feel like I have any information about the quality of the service or level of comfort before the flight. A lot of the cheaper and mid-range budget airlines are pretty much like-for-like in terms of experience, reviews are always skewed towards the negative and therefore don't contain too much useful information (people very rarely go online to write a good review after a comfortable flight with a cheap airline, but they absolutely do go online to complain and vent when it's uncomfortable) and anyway I don't feel like it's worth the time and effort to dig through reviews and try to find out what exactly my experience will be like on one 3 hour budget flight vs another, considering the amounts involved are not massive. Obviously I do go off my own experience, but even this varies from flight to flight with the same airline.

There's a lot of noise, therefore usually the easiest way to feel like you're getting the best value is simply to spend the lowest amount possible, assuming the experience will not be different enough to make you wish you'd spent more. To be honest, I think this is a decent strategy. It's very rare I've taken a flight and wished I'd spent $20 more on another airline to get a better cheese and crackers and coffee or a slightly more comfortable seat. These aren't differences which really matter in the budget short flights market.
As a dude, I am a fan of urinal dividers, but they are kinda uncommon, at least in the US.
Oh absolutely!

But that's not really constructive because you could say the same about 99% of social-network businesses, no?

You could also say: "It's not always the physical structure of a country that makes it great but its people (culture, history, how it started, so on) " and that would be true too. The fact that different websites have different 'cultures' make all the difference, right?

I like the artificial 140-char limitation though, but it would be comically easy to enforce it anywhere else.
What is the correct pronunciation of "brotli"? :)
> Perhaps Boeing and Airbus are overengineering their aircraft and baking in economic rent to a degree that makes the airlines fundamentally incapable of sustaining a profitable business model. Perhaps this industry can't actually survive with current technology and design methods absent some sort of government backstop or subsidy. Not sure. But the supply-side theory of this business seems like the most compelling (if not wholly complete) theory I've heard.

It sounds like you were never in enigneering. You never had to deal with building reliable system in regards of safety and high availability. And you even don't know what is really happening in that industry.

Just a small example Rollce Royce revolutionized that business years before IT invented the Cloud and XaaS (X as a service). RR is proving flying as a service since years. As an airline, you don't buy an airplane with engines. You as an airline decide and tell either Airbus or Boing what engines you like. Then RR (and others these days) don't sell you the engine. They sell you flight time. So RR is reponsible that the engines runs without downtimes. RR provide service staff at all major and many minor airports to be able to provide service. RR inventend the Internet of Things way before IT came even close to those ideas. Because to be able to sell airtime, RR needs to know about the status and diagnostics of those engines. Competitors to RR are doing the same since years.

Then, a modern aircraft is stuffed with electronics to replace mechanics, like your car. Because mechanics are wheigt. With electronics this weight can be reduced. It also allowed "services" like autonomous flying. Different to the car industry, almost any modern airplane from Airbus and Boing is able to completely fly on its own inclusive take-off and landing. Only taxiing is not possible.

But electronics have to problem of requiring redundancy to build highly available systems and all that with limited ressources. All way before IT has their 99.999 SAL and with much higher rates. We talk in these industries with undetected errors with a probability of 10^-15 and less.

>I realize that formal review of drug delivery products are important for safety

Can we be certain of that? How do we define safety? The FDA focuses on ensuring that no one is harmed by the use of a product, but they pay very little attention to those who are harmed by the lack of access to a product. The institutional incentives that exist encourage this conservative approach to drug access.

There are also many forms of regulation outside of governmental regulation. No bureau is needed to verify the quality of my Uber driver, but they still tend to be better than most taxis I've ever taken. 10 years ago you could have said "formal review of taxi drivers is important for safety" and most people would have agreed with you, but fortunately some entrepreneurs realized there was a better form of regulating driver quality.
Mastering for vinyl is very common in the industry. I don't have time to dig up a reference right now, but the medium has different constraints than digital so is usually mastered separately, especially for big budget stuff. The differing constraints are mainly that while CD has a hard amplitude limit (hence brickwall limiting), the constraint on vinyl is not hard in the same way -- it mostly has to do with amplitude of low frequencies and skipping grooves.
Japan had a financial crash in 1989. when their real estate bubble popped. Japan never fully came back from that.[1] Before the crash, Sony had their Aibo robot, and Honda had their Asimo. Sony had a small humanoid toy-sized robot in prototype, but never shipped it. Asimo work stalled; it's still around, and there's been some progress, but not much.

Robotics in the US has been heavily financed by the military. It took about $120 million to get Boston Dynamics to Big Dog.

It's not clear at all what Google is doing. Google bought all those robotics companies, but nothing has come out yet. Boston Dynamics, which Google bought, stopped updating their web site two years ago. They've demoed the old Boston Dynamics Atlas running in woods. That's about it. Google also bought Schaft, the Tokyo University spinoff, which had a very nice humanoid robot. (All-electric with liquid cooling, unlike Boston Dynamics' Atlas, which is hydraulic and far too heavy.) Schaft hasn't been heard from since. The question is whether Google's robotics groups are doing something really good, or getting nowhere, or the smart people have moved into some part of Google that makes money.

I don't know about music and audio, but your photography comparison is incorrect for two reasons.

First, as msandford pointed out, the human eye has significantly better dynamic range than image sensors. Technically, our eyes have a lower range at any specific instant, but due to the way our eyes work we effectively see upwards of 20 stops of dynamic range. The best sensors available (in medium format cameras, pro-DSLRs, etc) can only capture 14-15 stops.

Second, some black and white films have a better dynamic range than digital sensors, so it's also not the case that digital is strictly better. 18-20 stops isn't unheard of for some types of film.
The advice to use specific times to encourage punctuality has been going around for decades, if not longer. I recall reading this advice in the 1970s.

I don't know if there's any basis for this practice in fact, but I know of at least one second-order effect: When someone invites me to a meeting at an odd time, I always presume they are making an effort to get everyone to show up on time, and that motivates me to make sure I'm not the straggler!

I wanted to share this video about similar topic: https://www.youtube.com/watch?v=EYAcLudBbhg

This is about speaker in so called Islamic conference asking questions from the audience.

He first asks the audience if they feel they are extremists or they call themselves normal Muslims.

The he goes on to ask the audience to rise hands if they are proponents of stoning.

What we see is almost all the audience (including very young boys) except one man (perhaps few more) raising their hands in support.

You will see that these are not some crazy people in distant Afghanistan village - these are people living along with us in our society.

The question is - how should we deal with these people.
How does it differ? Well, for one thing you're not specifically repeatedly drawing the vapor from your cooking pan into your lungs; one hopes. For another the oil itself is not generally consumed but left behind after the cooking is done. Or so I gather, i'm no cook, but if oil cooking is done correctly hardly any of the oil remains on the food. Then there are some notable differences between a bit of food which is able to boil off its water content (keeping its own mass from getting to any ionization point) versus a tiny air-borne droplet of glycol or whatever. Anyway, i'd tend to wait at least a decade or so before the research was in. Just think how many years of tobacco smoking was going on before publicly declared a health hazard.
I agree with this article whole heartedly. It made science accessible to the general public.
Yes, but obviously they don't work if your signal is already aliased. The most common example would be when decimating a signal, e.g using a digital filter with a cutoff at 22khz before down sampling from 192kHz to 44.1kHz. This is often realized in a single step... Check out polyphase interpolation/decimation if you're interested in learning more
Sure you can modify it, but only trivial things like scaling, chopping of a part, and if you are lucky, meshing it with some other part, will be easy.

Say for instance you want to do something simple, like use another sized tuning pegs for this violin. That means changing the diameter (and possibly depth) of the holes they go into.
In any reasonable parametric CAD software model (as Fusion 360 enourages), this is merely finding the sub-part that represents the peg or peghole, and entering in a new value for the diameter - every affected area of the model will be updated, correct & still manifold (watertight).
With an .STL you will need to find & select all the relevant edges/vertices for each hole, and nudge them around until they (hopefully) fit.
This is a trivial example, it becomes more interesting (more painful) if the feature at hand is more complex. Say if there was a trapped nut.

In an STL, all the humanly meaningful parts of why the model is the way it is, how it is built, is gone.

You can dissassemble some executable you get too, and muck around with the code to do modifications - but its hardly how one should do open source.
Well, the entire point of Math is that you don't need to learn history to use and improve it. Yes, you can learn a bit from history, but it's very limited, and too specific to help in most situations.

And before you ask, I've read Shannon, and Hamming. Didn't read CS Turing papers (did read some others), and I guess there's no further information there that I don't know already. I've also read about the first crypto wars, and quite a lot about economics - enough to know this article is complete bullshit; the author complains that developers don't practice the most damaging practices of economists. Besides, get me a keynesianist that has read Keynes.

If you came complaining that people mostly lack basic mathematical knowledge about crypto, and don't know the best practices about software architecture, I'd completely agree. I'll also agree that history is a great tool for making the mathematical and anedonctal knowledge easier to digest. But no, it's not very valuable by itself.

Marginally effective because it creates a dependence that ceases to become as effective as the onset and you merely end up with an addiction.

Marijuana, on the other hand, produces consistent highs and its effects reach deeper than mere pain relief though it's good for that too. Pot does seem to dull intelligence because it slows people down. This is not a sign of loss of intelligence however. In fact, the real culprit behind dulling of intelligence is alcohol.

----

In terms of marijuana and its effects on brain cells, or neurons, there is little evidence to suggest that any of the active ingredients in the marijuana plant administered at doses appropriate for human consumption have neurotoxic effects.

This is in direct contrast to alcohol, where the body’s digestive process creates metabolites such as acetaldehyde and other “reactive oxygen species” which are toxic to the brain and other cells in the body. This is why you have a hangover, after drinking large quantities of alcohol.

Did your return key break..? ;-)
There are big problems with addiction studies in general - in this case because needing a cup of coffee to start your day is considered just fine, whereas needing a drink to start your day is considered pathological.

Being grumpy because of lack of coffee is generally understood and sympathized with. Being grumpy because you haven't had a bump today is considered a cocaine problem and compulsive behavior.

There is so much socialization and stigma around various substances, that terms like compulsive and pathological are hard to use objectively.

Is there a difference? Audio is one-dimensional, frequency is just the derivative of amplitude. An arbitrarily high frequency sound wave becoming louder and softer 440 times per second is just as much an A as a 440 Hz sound wave at constant volume. A lot of cheap audio gear even uses a "1-bit DAC" that is just very high frequency PWM.
