When I use it for boxing, the calorie burn graph seems to very closely follow the heart rate graph. But only if the tracker was in exercise mode (longpress the button).

As for the article about inaccuracies. Their manual clearly states that during exercises that involve a lot of forearm flexing and vigorous arm movements the tracker will be inaccurate.

And I am sceptical that people wouldn't be able to tell from how they're feeling that they are at a dangerously high heart rate. But I guess it's possible.

The highest number my fitbit ever reported was about 170 (sprinting) so it's definitely cspable of measuring high heart rates.

"Software development is hard. Adobe's software is incredibly complex. Sure this sucks, but it's worth keeping that in mind before blasting Adobe."

The sentiment is solid, but this is a major software company dropping an update that fails to do BASIC checks (like "is the target directory named what I expect?") before permanently deleting data. Blasting is entirely appropriate.
I once received feedback after being rejected for a position. In this particular case I knew full well why I hadn't been given me the job, but nonetheless their willingness to open up about their decision making process made a big and lasting impression on me.

Of course, it was a startup. No company with more than 20 employees would probably even consider doing something like this, and unfortunately I doubt that will change anytime soon. However - if you're ever in a position to safely communicate with a rejected candidate, I would suggest you at least consider it. They may not be suitable now, but things do change.

At the other end of the spectrum are companies or teams that don't even bother notifying candidates they've been rejected. I'm sure they have good reasons, but to me that sends a negative signal.
Voxy Is Hiring a Project Manager (NYC, Sao Paulo)
Yes, you can very much look at this as the owners of the tech company taking money out of it and doing something else with it. Google the tech company is hugely profitable, this is not a weird thing for them to do.
Google Fit tracks the repetitive movements of gym exercises as steps. Maybe Fitbit does the same.

Probably they would also track sex as steps. Now I want to see somebody reach 10.000 steps!
I get it, lawsuits. There's very little upside for the employer, the benefit would go to the candidate, and the liability is on the employer. I suppose one benefit for the employer might be that the candidate could improve, should there be an opportunity to interview again later.

It's a problem, though. I once did a 7 hour take home exam, didn't hear back for a month, and finally got the one line rejection listed in this article "we've decided not to move forward…" A month is too long to make someone wait regardless, but I really would have appreciated some technical feedback, because all I could do is wonder. The test was in Java, and I did use what I believe is a somewhat outdated way of using threads, but that's just a guess… I also interviewed at Google, and I understand that this "exam" (I think we should start calling it an entrance exam rather than an interviews) does result in actual, numerical scores that are currently sitting in a database somewhere at google, but I'm not allowed to know what they are. Again, I'd really like to know. Was I way off, or close? No idea.

I think this becomes especially toxic in the context of tech interviews, because they really do often amount to exams. I've spent some time reflecting on this, and I believe that exams usually come with a bill of rights for the examinee (or student). It's very unusual to take an entrance exam with no idea who will evaluate it, how it will evaluated, how you did, and why you did (or didn't) pass.

This "bill or rights" isn't an accident, it evolved, I believe, to counter balance what we demand of a student, and to provide safeguards against abusive and capricious behavior from institutions that act as gatekeepers, whether it's the bar, the medical or nursing boards, a committee deciding whether to award a masters degree, and so forth.

I understand why liability terrifies employers, and that there is no real benefit for them. But unfortunately, you do need to look at this from the perspective of the people who take the exam. We get all the negatives of high stakes and stressful exams, but without the considerations that offset the stress and safeguard against abuse. There may be reasons for it, but developers are the ones who don't really know why their performance at the whiteboard wasn't acceptable enough for a job offer, or what happened after they sent their take home exam to a recruiter where supposedly it was evaluated by a tech team.

In short, just because there are good reasons an employer wouldn't want to do this doesn't make it acceptable from the perspective of an applicant who has to essentially sit for these exams.

I consider this a very serious problem in the high tech industry, and is certainly something that deters talented people from entering or remaining in the field.
This was my experience as well. It was refreshing.

Is resting heart rate a good indicator either? Mine is typically 55-58bpm but I do no organized exercise and am sitting for much of the day (I do try to walk quick and run up stairs to make up for it, so while I'm not "fit", I don't feel unfit per se).

I am free from cardiac related symptoms, so does this mean I am "naturally" fit without really trying? (A bit like people who don't focus on their diet but are slim.) Or, as I suspect, is resting heart rate not a very useful indicator of fitness at all?
Bang on! At least if you made a reasonable wage it would be worth it, but everyone in Vancouver, including NHL superstars like the (Sedin) twins take a pay cut because they claim to love the opportunity to stay there. Every Vancouver employer I ever had gave me that line. "Sorry we can't pay you more, but you know, the rents! This is a great opportunity for you though". Later I found out that I made about 25-50% more than my colleagues, and I was vastly underpaid. It is a horrible work culture.
The problem is staying becomes increasing attractive over time. Retired people save money by staying put, young workers can't afford to move in. This breaks the housing market.

SF is not a housing market it's effectively a planned communist community with a few bribes on the open market.
In my case (not op) I don't belong to a traditional gym and go rock climbing several times a week. I don't really care to go for a run but I love climbing. Also my knees are in bad shape because I am both tall and heavy which means running/biking/anything where I regularly move my knees hurts. Climbing is nice because most of the time unless I am trying to dyno (jump) to a hold I only use my feet to keep myself against the wall or to statically take my weight while I move my hands.

The Fifth Amendment was intended to prevent torture and coerced confessions. It doesn't hide a general right to conceal evidence, which is itself a crime in many places in the US.
Just curious: do these folks have any id?

Some do, many don't. Either way doesn't say much about where they were living 2 or 20 years ago.

Could we perhaps google them vs housing records, property deeds, or other public information and determine if they used to own or rent in SF?

You "could" but it would be a pretty bad idea -- it's safe to assume most of these people weren't ever property owners, and (if they did rent) lived in regular privately-rented dwellings, i.e. with no public record.
I thought the GP's comment was on fleek!

Seriously, though, his use of the word hack was obviously intended to disarm the GGP's implied argument. It made me chuckle, and I think was a good word choice despite it's "tedious zeitgeistiness".
> There are a lot of ways to do that, and many of them involve the current team members being proactive about going out and trying to recruit someone to fill that role.

Orrrr the current team members can be proactive and do something that will reduce the number of bad bug reports they get.

I just recently read that BMI is turning out to be a not so great measure of things now.

I always make a point of trying to give unsuccessful candidates feedback - especially when it's "we love your enthusiasm, get some experience under your belt and let's talk again".

A candidate who didn't get hired and came back stronger is EXACTLY who I want working with me, and its shortsighted of companies to burn off a candidate as soon as they stumble on fizzbuzz or something equally bullshitty.
I say exactly the opposite: you can use taxing to make people buy more of something (some new tech you want to push) or less (e.g. cigarettes).

This is assuming that substitution effects invariably or above sufficient thresholds dominate over income effects, which in the case of addiction is a dubious proposition.

My students talk of a much greater "creep factor" in that they now assume everything done via facebook is being examined by men in black suits behind concrete walls, or fat men in basements wearing sweatpants. It's no longer considered an appropriate place for candid conversation.

Perhaps the owners are looking for a 'fountain of youth' for themselves, and simply directing some of Googles resources in that direction.
In practice you can't, but you can short the banks lending into this bubble. Also building companies can be shorted.

The problem with going short on something like housing is the market can stay irrational longer than you can stay solvent. This bubble is being pushed by buyers who are not looking to make money, but to get money out of certain countries and providing a safe haven to flee to. Unless this changes then things won't get more rational.

If you had enough money you could short the banks and then whip up a media campaign of anti-foreign investment and xenophobia. Scare the market enough and you might get it to crash.

Do you value "equality" at all? E.g. do you find huge inheritance unfair (because it's something you didn't produce) or not? How about "proportionate representation" (one person, one vote, as opposed to the current situation where rich have vastly more political power)?
How do I scroll through my entire photo collection in Lightroom with it keeping my folder tree in sync as I scroll and dividers by folder so I distinguish between groups of photos?

As far I can tell in Lightroom my old options are (1) show all photos from all folders in one giant grid so I can't tell where one folder starts and another ends nor can I tell which set of photos I'm currently looking at. Or (2) only view one folder at a time

Nothing unknown was said in this article.
I don't think that's an appropriate analogy. You may as well just say "In the 1700s, if you wrote an enciphered letter..." since cryptography isn't a new concept. Various schemes have been used to protect military and diplomatic communications for centuries. If you did so then or now, you wouldn't be under any obligation to reveal the contents, but you take on the additional burden of actually performing all of the necessary calculations, securely destroying the scratch paper you used in the process of encrypting the message, handling key management and distribution, securing the areas where the encrypting/decrypting is taking place (you wouldn't want the redcoats barging in the hour or so while you're in the middle of converting the plaintext to ciphertext), etc.

Nobody does that anymore. You're instead using a tool that someone else made, and either that tool or the other person is handling all of the hard work. Tools definitely can be regulated - I need a license to drive; I need to register my car; I need to go through a background check to own a gun; I can own a gun, but if I misuse it I go to jail; felons can't purchase guns legally; I can't buy a nuclear weapon or the fissile material needed to make own.

The questions that policymakers are fumbling through right now are things like "how (if at all) do we regulate tools and the companies that make/distribute them if those tools allow people evade law enforcement?"
Capitalism is an economic system first named and characterized by its critics for the way it favored holders of capital, not least of which the way its structure of property rights enabled and rewarded rent-seeking.

In this case, saying "this isn't capitalism, it's rent-seeking" is like saying, as you sail out of the Golden Gate, "this isn't the ocean, its salt water."

(That is, its wrong because the thing being described is both the thing it is denied to be and the thing it is proposed to be instead, and the latter is central characteristic of the former.)

The mutual fund itself is tax-exempt and passes profits and gains onto owners of the fund. Think about the alternative: you create a corporation to hold the assets of the fund. Dividends on those assets would be taxed when the corporation receives them before they are distributed to shareholders.

This seems far-fetched. Encryption has historically had zero effect on law enforcement, but collection of electronic evidence has made thousands of felony cases. Meanwhile, the issue isn't simply what criminals encrypt today, but the fact that everything they do will be encrypted in 15 years.

That's a good point and one that's starting to change a bit with the rise of integrated health systems (payor and provider integration). Intermountain Healthcare is one such organization.
I think this is more or less common knowledge that the higher the intensity of exercise the less time or "steps" in this case is needed to achieve the same goal.

There is a curve ball however that needs to be taken into the account - the question is what exactly your goal is?
For example, a sprinter and a long distance runner might be averaging the same BPM rate over the course of the week both resting and during their workouts, the end result is quite different however.

I myself have always been a proponent of high intensity training for everything - short and intense weight lifting workouts, sprinting etc. This changed when at one point in my athletic "career" I switched to boxing at a relatively young age (under 20 y.o.) and my shins/calves started getting sore to the point where it was difficult to walk.

The way to condition those for relatively low-intensity but long (2+ hour) workouts? Even longer and lower intensity workouts basically just walking around or light jogging for hours.
I've seen sex get recognized as "Sport" by the Fitbit "auto-detect" feature. Also does count steps.
One big advantage to composting is that little bits of food clinging to the container are a feature, not a bug.

So it saves a lot of water and (if hot water is needed) energy over washing and recycling paper or (with PLA and such) plastic.

The composting facilities I'm aware of are for-profit, but they typically get paid at both ends of the business (http://cedar-grove.com/about-us/faq/).

They absolutely can ban encryption if they want. Just like they can ban mathematics. What makes you think it's impossible?

It wouldn't immediately eliminate all encryption, but it'd be easy to go after any corporations operating in the US and either force them to follow the ban or throw their execs in jail. After that, they could put up a Great Firewall and block downloads from foreign servers. They can use the Great Firewall to snoop on internet traffic, doing deep packet inspection, and look for unrecognized traffic, VPNs, encrypted emails, any markers of common unauthorized encryption protocols, etc. They don't have to catch every single person, they just have to catch some and then make an example out of them.

You're probably thinking that this is just too extreme. Has everyone forgotten what life was like in East Germany under the Stasi? That lasted until the late 1980s!

Now of course, you can debate how unlikely this scenario is to play out, but I'm just pointing out that it isn't impossible, not at all, and we've seen a society much like this in the very recent past.
How come your graphs do not go below a resting heart rate of 70? If you look at http://www.cdc.gov/nchs/data/nhsr/nhsr041.pdf, about half the population should be below that.

The only explanations I can think of are either that Apple Watch owners are a non-representative sample (possibly true. But _that_ non-representative?) or that you do not manage to measure resting heart rate that well (how good is the Apple Watch at measuring heart rate?)
Never heard of that. Trippy. I always wanted to try the Crane and Piantanida experiment to see what those colors looked like. Was afraid it would screw up my brain haha.
You have a point there: pistol grips do have a small but useful function.

Now, change it to "bayonet mounts", which is another feature that was listed on the "Assault Weapons Ban" law. How does having a bayonet aid someone in a mass shooting? In fact, when has a mass shooter ever had a bayonet mounted on his rifle? I'm not even sure why they bother with them any more; I've never seen any pictures with US military servicemen in combat in the last 20 years with bayonets mounted in their M-16s or M-4s.

Another thing was flash suppressors. How is banning those going to prevent mass shootings? The whole point of a flash suppressor is so the enemy on a battlefield can't tell where gunfire is coming from exactly. Someone walking into a movie theater isn't all that worried about return fire, and in a room that size when he enters through the emergency-exit door, it's not like he's going to be well-hidden.

But seriously, the whole thing is pretty dumb IMO. They tried to ban very, very minor features (pistol grips, flash suppressors, barrel shrouds, etc.), but ignored the things that really made these weapons good at shooting lots of people, namely semiautomatic operation and easily-swapped magazines. If you want to make mass shootings hard, ban magazine-fed ammunition and semiautomatic operation. Of course, that'll bring you right back to Old West 6-shooters (well, modern .357 Magnum revolvers would still be legal too, but you could also ban that style of revolver where the cylinder is easily opened and reloaded with a speedloader; the Old West revolvers didn't have that, you had to reload them one at a time, very slowly). But of course they know that'll never work since people have had semiauto guns for a century or more now and aren't going to turn them all in, so they go for a feel-good measure that'll make ignorant anti-gun voters happy without actually changing anything substantive.
