They did not report their methods for the ecig sample acquisition. It's quite possible that they were not using the vaporizer under the normal conditions. There was a previous study where they were running the device at excessive voltages over tens of seconds, causing pyrolysis which would never happen under normal usage. Simply because it would taste awful and make the user cough a lot.

I would have liked to see control experiments: analyse the e-liquid without vaporization, and analyse pure glycerol/propylene glycol. The former may show a response, but the latter should not show any at all.
Not just in Canada. I'm about to graduate in the third largest city in my state, and I can only find jobs that pay around $35k/yr. The fact is that most new or good paying jobs are being concentrated to only a few areas of the country. They form economic bubbles that are insulated from the fact that most of the country is seeing a decline in quality of life due to lower wages, higher costs, and less worker leverage. This economic ignorance is a big reason why big cities don't understand the rise of Trump.
In what way is electronic music meaningfully cheaper to make? You still need to book a studio unless you're going pure instrumental, and that's where the cost is. I guess you get to cut out a dependency on studio musicians, but I don't think studio musicians actually get paid that much.
TL;DR: The author writes a snippet of C++ code where he declares variable but not initializes them. Of course any programmer that has started in C knows that such variables will then have unexpected values.

The author recommends us: "initialize your variables."

Then follows a interesting and fun, but not really important, review of the different ways if initialization in C++. And they are bonkers.
"can NN be applied to X class of problems with no human-added domain specific knowledge"

Universal approximation theory suggest that for a significant class of problems, the answer to this is "obviously" [1]. The problem that remains is how effective is the learning.

I'm not convinced applying them to areas like this one where the are clearly much better approaches teaches us anything useful for more interesting cases, but maybe it does.

I was one of those people who was pretty well convinced that e-cigarettes and cigarettes were both about equal as far as danger due to the nicotine. E-cigarettes delivering on average throughout the day more nicotine than cigarettes. And cigarettes, delivering ash.

A few years ago I read a convincing article to the contrary from the NHS. Detailing how the most dangerous carcinogens came from combustion of tobacco.

Smoking related signalling has been a train wreck for a decade or more now, so of course after this article came out the very same NHS started talking about banning certain types of e-cigarettes. I don't know what's going on anymore. It doesn't help that there are zealots that spam information about e-cigarettes being perfectly safe, and charities that spam information about cigarettes killing you and everyone around you so donate right away.

The internet has utterly failed us on data about smoking. If anyone knows what's actually going on, then they are lost in a sea of other people that are doing their best to shout over one another.

> Denmark is one of the very few countries (two if I'm not mistaken) that takes cycling seriously

Considering the cars have a 180% import tax, a big percentage of the population couldn't afford a car even if they wanted to. So I'd hope they take it seriously.

> They also have good public transport compared to many other countries.

Given that this portion wouldn't have a way to get around without it, this seems like an absolute necessity which isn't necessarily the case in other cities. Poor people need to get to work somehow and reach shopping centers and family/friends outside of walking/biking distance.

That said I'm fully in support buses/trains and biking. I bike everywhere and live in a city but still own a cheap car, which I still get a great amount of value out of and find indispensable. It is also important for my partners work who occasionally needs to drive to surrounding areas.
YMMV but in my experience the most challenging projects were personal ones. Why not in the job? Because all the stake holders are interested in making the projects not too difficult or experiment, so they get realized. For my own projects I can make them as unrealistic as I wish. So of course the failure rate is also much higher than for my professional work. That way I got unusually proficient in certain technologies.

Publishing on the App Store is not really relevant. I can experiment, write code, and publish that code without Apple's blessing.

Any curated stores (stores for web apps are no exception — like the Chrome store) are going to put limits on what can be published. That is where their value lies.

Here's the dilemma: To have a degree of openness and accessibility for developers while also maintaining convenience for end-users, you have to accept the submissions of new developers that meet a certain (in practical terms, low) bar of standards. So to curate such an ecosystem, while being relatively open to new developers and users at the same time, the below-par apps have to be punished through discover-ability. This is what Apple has done, and it explains why their ecosystem is painful in exactly the ways it it painful. (It's not as painful if you are working at a good company with sharp marketers, or if you have an in with a community that exists outside the app store.)

The web simply has its 'knobs' set differently to mediate the curation/openness dilemma. Discover-ability is better. Curation is DIY/free-market. Caveat emptor.
It would be interesting to quantify this.

> discouraging non-smokers is a great idea
Thank you, I hadn't thought about that before and you're completely right.

If the risk profile for cigarettes is just barely too high for a non-smoker then e-cigarettes may be the last 'push' Although this does require some assumptions about why individuals start smoking cigarettes in the first place.

I think you're right as well. A lot of the distinctiveness of sounds in popular music were driven by improvements in technology in the 60s through the 80s or 90s, but that's no longer the case. The same can be said about movies up to the last several years.

With the exception of (the scourge of) Autotune, has any technology really changed how music sounds since the tidal wave of digital sampling in the early to mid 80s?

Similarly, the massive advances in computer graphics have radically altered movie making in the 80s through 2010 or so, but those advances are becoming much less noticeable from year to year.

My issue with non-competes is that the vast majority of people who sign them don't understand what they are signing, nor do they negotiate the terms. They feel that they are in a weak position; it's the first day of a job and if they don't sign they'll be unemployed. What's worse is that you are generally presented with a stack of paperwork to sign and told it's just a formality.

There's also the misunderstanding that everything you sign is binding, it's not uncommon in CA for employees to sign what looks like a non-compete, and then believe that it is enforceable. Very few people have a lawyer, or can afford to pay a lawyer to review these agreements. Even fewer are brave enough not to sign them then and there.

I've seen some very egregious language before, one of my favorites was one that restricted the employee from working for any past, present, or future (defined as one year) customers of the employer--and their future employers from the same! I've got no idea how this was supposed to be enforced, but it caused the signee to be in fear of being sued.
Oh okay thanks for clarifying.

But how can insurance not be perverse? If it is not nationalized then it is a private company that needs to make profits. And when you have that incentive, it is all about stats and risk. I find it a difficult problem to mix with capitalism. I have been raised in Europe and for me it is natural that one can go to the doctor 'for free' (if you cannot pay for it); I am trying to reason how insurance would ever work unless (like in NL) insurers must accept everyone no matter what happened before. How would that work? Is it not better for the insurance company to have people without money die? How can that fit?

It's sort of like the classic market segmentation problem. Ideally you want to charge each customer the maximum price they're willing to pay, but it's hard to give different prices to different people. Likewise, you want to push each person towards the least harmful version of smoking or non-smoking they'll accept, but you can't tailor general advice like that.

In any case, it seems like much of the e-cig debate comes down to this. Those in favor see it as an alternative to cigarettes for smokers. Those against see it as a way to get non-smokers to consume tobacco.

Anecdotally: my mother frequently smokes regular cigarettes, she'll light one for a few 'puffs' then put it out.

To combat this, tobacco companies put some sugar on the filter tip and I believe better tobacco in the very tip of the cigarette, this way the first hit is better than all of the others.
So by forcing everyone to work strict 9-5 schedules you can create diversity. Ok.

Hmmmm... I agree at least in principle that one shouldn't be required to always hangout late nights after work. However, admittedly occasionally I think it's useful and it's helpful to understand your co-worker's motivations and spending a bit more time with co-workers sometimes is certainly reasonable and helps to build trust and respect amongst other co-workers.

Maybe people should be working only 30 hours a week and spending the other 10 hours just on team building.

I also think its useful to understand the social aspect of things because understanding motivations can help the team solve problems in a way that everyone will agree to.

I smoked cigarettes in the past and used ecigs to make cessation easier. When I switched, I used the vape more than cigarettes, but I also had a lot easier of a time quitting the vape(due to the lack of MAOI I believe). Even if people vape more than smoke, it may be worth it if they​ use it to successfully quit smoking altogether.
If i consume 100 smokes vs 100 vapes equivalent then what will be the total damage done to the enviornment in each case,starting from the production to disposal?
I really don't agree. I'm pretty confident in my ability to do what I do, but having a cofounder has given me a useful critic (amongst other things). Having gone through this stuff, I would have wanted to have done it on my own. *

> just relaying the advice of a somewhat successful man

This is a fallacy. Unless it's backed up by really good reasoning, I wouldn't take someone's advice seriously _simply because_ s/he has been successful at _something_. There are too many factors at play and way too much context to make it meaningful unless it obviously translates to the situation at hand. I can't think of a plausible reason why having a business partner is, 100% of the time, a bad thing (which is what is suggested in this anecdote).

* caveats: "having a cofounder" is obviously not a panacea, and may not be a good thing if you don't have the right relationship (which seems fairly clear from the OP)

Yes, I spend an inordinate amount of time working on my skills, but I'm under no delusion that it's just those skills per se that have gotten me where I am. In many places in the world, tech jobs are not paid that much more. I simply don't see how the IT world is a meritocracy. I do see how it appears to be one, however. It's not.

Sorry if I was unclear. I was trying to understand and respond to your comment that it's not immoral to let a human being die when their organs fail. I argue that the moral worth of a specimen of homo sapiens is not in the function of their organs, which would lose that value when the organs cease to function, but in the function of their mind. Because that value could be preserved through donation of a kidney, policy which prevents that from happening is an immoral act.

> What happens when the remaining kidney of a poor donor fails? But you hand waves it by saying it is not a problem if they can afford it, when the whole reason they sold the kidney was they were poor!

Kidney transplants for both rich and poor are, and will be, covered by medical insurance or universal health care. Whether you ever need one or not, on average, you will pay your share of approximately 1/350th the cost of a kidney replacement as a member of modern society. In today's market, with expensive dialysis frequently used in place of unavailable kidneys, that results in about 6% of the Medicaid budget going to treatment for kidney failure. I expect that this cost would be reduced if kidneys were more available.

> Now the rich wants to "help" the poor by enabling them to sell their kidneys!! Oh the hypocrisy!

This is not hypocrisy in the slightest. The rich and the poor want to help the rich and the poor by making everyone's kidneys available to everyone that needs them. I'm both healthier and wealthier than the general population, and would welcome the opportunity to donate a kidney, similar to the fashion in which I donate blood on a regular basis. But my current medical insurance will not pay for a living donation to anyone who is not a family member or friend, and I could have higher insurance costs in the future if I volunteered to give one of mine away, to say nothing of the small risk I would incur. I am wealthy, but not so wealthy that I can afford to donate my kidney, donate the cost of the procedure, and donate the cost of future insurance. I'm not suggesting the donation should make people rich, but rather that it would let them break even.
