Manually (as in manus, the hand) measuring your pulse while not at rest (sitting down, in a calm environment) is so error prone, it's almost useless.

The only proper comparison would be with a chest strep, which are much more accurate.

Also, it really differs per person and how you wear the watch. Just wearing it a bit differently can change the results significantly.

Sweat also gets them messed up easily.

All reasons why, if you want accurate data for workouts, you should always use a chest strep. Even if they are much more awkward.
It's true that these companies are not offering "sequencing" per se but rather are genotyping commonly polymorphic SNPs using an array or other genotyping method.

These SNP arrays, however, are exceedingly accurate and reproducible in their calls. A common medium-density SNP array used for human genetics is the Illumina CytoSNP-850K [1], which routinely gets >99.5% accuracy on calls. This is at least as good, or better than, whole genome sequencing.

The challenge in ancestry assignment is not determining what is in the sample, but rather in the interpretation and assignment of ancestral haplotypes.

Unfortunate news; though most won't miss it, I will. It was the last smartphone option that avoided both the Scylla of Google's data vacuuming and the Charybdis of Apple's pricey walled garden and their "my way or the highway" design philosophy. Plus, the live tiles are actually useful in a smartphone context.

Microsoft (and by that I mean both Arbogast and Myerson) was just plain stupid to break app compatibility multiple times between Windows Mobile 6.x and Windows Phone 10. What exactly did they think was going to happen to their app count after pissing off their developer base?

"...greater use of effective strategies did not explain the persistence of the grittier types"

"however...the greater use of these two effective strategies did not explain why these high trait self-control individuals tended to enjoy greater success at aversive challenges"

So, in fact, this study identified which strategies were effective in people who were (self-reportedly) already effective at handling aversive tasks.
I started doing this, and the first stumbling block I hit was simply assessing at what level my math education falls apart and figuring out what courses I needed to refresh with, what materials I needed etc.

There's a market opportunity for building a math placement test product, or even better a fully automated math education platform with examinations at each stage, that takes you from K-12 refreshers all the way up to grad school. Something a bit more advanced than the existing online learning programs that are still very much based on the college lecture model.

There's a lot of products out there that do this for software development, but not for other subjects. I have noticed there are bits and pieces I can download as mobile apps, but they are designed to be supplements to certain college curriculum rather than an end-to-end education.

Obviously math is a subject where software is an optimal instructional tool, so much more could be done here
As I understand it, some small Indian tribes already have something very much like guaranteed income for their members, funded from casino profits. Anecdotally, the outcomes seem to mildly positive - worth noting, but not that dramatic; the social issues in Indian country are quite simply huge, and it's not quite clear that even a guaranteed income is enough to make a dent. I'm not aware of any formal academic paper analyzing these outcomes, however.
Not sure if you're just trolling or not, but I'm genuinely interested in understanding your perspective more. Although I don't expect you to take my word for it, I'm very open minded on this subject. I went vegan at one point.

However, is it really less ethical to raise animals (in humane circumstances, open pasture, etc) and butcher them quickly than to either:

a. Cause them to never exist and never experience life at all (presupposes that one places higher value on existence than non-existence, which is philosophically debatable of course)

b. Cause them to die a natural death at the hands of either predators that will mangle and mutilate them, or to disease which is a slow and terrible way to go?

I've never seen such cruelty as is found in nature. Even just seeing what the neighborhood cats do to the birds makes my stomach turn. I think if I were mangled and blinded, I'd be begging for somebody to kill me quickly.
If you have AT&T they have an app called AT&T Call Protect which is pretty good at blocking fraud/spam calls. Free version is fine, haven't used the paid version.
Think of a genome as 3 billion character sequence. "Sequencing" a genome gives you the actual content of the sequence. Think: "....GAAAAGATACCCACAGAGATTACAAAAC...." (I'll call this string FOO)
Until recently, sequencing an entire genome was really, really expensive. I'm not sure what the price is now, but I know that it has dropped considerably.

When you sample a genome, you're checking for one specific string. Traditionally this is done by mixing a sample of the DNA with an enzyme that breaks apart a specific DNA sequence and then measuring whether the size of the DNA molecules have changed. Take the string that I mentioned above (FOO). Suppose that I mix it with an enzyme that cleaves along "GATTACA" such that "GATTACA" becomes "GAT| |TACA". If I mix a DNA sample containing the string FOO with the enzyme I just mentioned, then the molecule would be split into:
"....GAAAAGATACCCACAGAGAT| |TACAAAAC...."
If I mix a DNA sample that does _not_ contain FOO with the enzyme, no change occurs.

You know when you watch CSI shows* and the DNA evidence is presented as a bunch of light and dark bands? Those are produced by mixing the suspect's DNA sample with a standard cocktail of enzymes, treating them so that the DNA molecules are electrically charged (DNA might already have a charge, not sure), placing them at one end of a container of a standard gelatin with known pore size, and applying an electric field for a standard amount of time. The cocktail of enzymes cleaves the DNA at multiple different substrings and breaks down the DNA strands into multiple smaller substrings. Different size molecules will progress through the gelatin at different rates, so you can effectively compare two people's DNA to see whether the substrings match. You _don't_ know the person's genetic sequence, just whether or not his or her's DNA contains the same substrings as the DNA of the person that you're comparing it to.

* I'm assuming those TV shows present the DNA evidence this way. I don't watch them.

>It's not even like it's not been tried before - TFA posits that marginal tax was 90% in the 60s yet I'm pretty sure that life is better now than it was then.

To nitpick here a bit, it's funny that you call out his argument as being blatantly incorrect while making a blatantly incorrect one yourself.

There are many things that have contributed to the reasons why overall QoL has gone up and trying to correlate lower taxes to better QoL is absurd, considering we've seen the improvements globally in places with both high and low tax rates.
Even if the tech was the same, couldn't they just run the less accurate test several times to increase the confidence?

If the CO and XO are so critical that the ship needs one of them during normal operations I think there is a bigger problem.

What happens if one of them is incapacitated? The ship is ineffective for half of every day?

This is always true for complicated technical things. How many people can really accurately explain what “The Cloud” is? Wouldn’t you say the mainstream public is aware of “the cloud”.

I guess my original post doesn’t really discredit the main point being made which is that people aren’t aware of Butcoin’s scaling issues. I agree with that.

I do think it’s interesting that the bubble crashed once Bitcoin as a general concept was no longer really new for anyone.
Why would you plan to continuously use band-aids when you could prevent getting cuts in the first place?

It seems more important to address the source of the issue to prevent it from continuing to occur rather than only treating the symptoms. (Fixing the current is still important, but seems secondary to me)
That is some impressively hand-wavy equivalency. Plato predicted something pretty much entirely wrong and you're pretending he was generally correct. Plato believed, without evidence, that there were some indivisible units of matter. That's all he got right (and even that was arguably incorrect given subatomic particles).
I've long wished for a series of interactive ebooks or websites based on that type of approach. Each would be devoted to one great theorem or problem.

Each would start with a presentation of the theorem and proof, presented how it would be presented today if it were a newly discovered research result being presented by professionals to professionals in the field.

At each step of the presentation, there would be two expansion options. One is to ask for filling in the details. A detail expansion keeps the presentation at about the same level of required knowledge, but takes smaller steps. You use a detail expansion when you understand where a step starts and end, but you just don't quite see how it made the connection.

The other expansion option is to ask for background or prerequisites. A background expansion is for when you don't have the background to even understand the start and end points of a step. It opens up material to teach you the background necessary to understand what is going on.

A key aspect is that this would all be recursive. You could do a background expansion on a background expansion, and so on, all the way back to common high school math.

The background expansions would just teach enough of their subject to support the step above. So, for example, if you used one of these interactive books to learn an analytic proof of the prime number theorem, and you started knowing nothing beyond high school algebra, you would end up learning all the calculus and complex analysis needed to prove PNT, but only such calculus and complex analysis as are needed.

What I wonder is if you could pick a set of theorems and problems for such books such that (1) someone could go through them all in about the same time as a conventional math degree takes, and (2) combined, the background expansions would have covered as much as a conventional degree.

If so, that could be an interesting way to keep motivation high because everything you are learning has a direct, visible, connection to advancing the proof of the interesting theorem at the top.
Shouldn't this involve lots of penalties? This has the potential to change/ruin lives drastically. A prudent consumer never trusts what the companies say nowadays. However, that shouldn't absolve the company of falsely claiming private product when it isn't so.
Why should that be disturbing to some people? I think the vast majority of people, at least in America, have no idea where their ancestors came from. Is the usual "I'm part Irish part German part Cherokee" meaningfully more satisfying than "I'm west African?"

I don't think it's a good thing for people to attempt to derive any aspect of their identity from their genealogical ancestry, it has no bearing on who you are as a person, and has the potential for great harm. I've seen it used to give people a false sense of culture and belonging to a community that they previously had nothing to do with. If you felt a connection to a particular culture or identity, should we really be telling people that their genome is responsible for determining whether or not they can associate parts of those cultures with themselves?

Racism results from a failure to separate identity from genome. If you listen to the dogma of a white supremacist, it's heavily predicated on associating the accomplishments of their "European" forefathers with themselves. If you listen to the dogma of a black supremacist, it's heavily predicated on assuming the identity of the Egyptians or Israelites and associating their accomplishments with themselves.

I really think that if an individual is truly "disturbed" by not knowing the precise nature of their lineage, that is an individual in search of an identity on a plate, and therefore highly corruptible. The motivation to learn more about one's ancestry should ideally not surpass the level of an intellectual curiosity.
Comparing two DNA samples for identification of a culprit is totally different from determining the percentage of differing heritages that make up your DNA.

Frankly I am skeptical that they could even ascertain any semblance of your heritage but I'm definitely a layperson.

There may be a tiny minority of farms in pristine locations that will eventually get pushed off their land, but I suspect the vast majority are in areas where the land is absolutely undesirable for anything besides farming.

Note that you can combine the two approaches: Small charges for unverified calls and zero charge for verified ones. This seems to get the best of both worlds.

The US Navy doesn't own any battleships. After fleet carriers, the next level is going to be destroyers and missile cruisers.

According to Wikipedia, the US decommissioned its last battleship in 1992. Even then, the US Navy largely forswore battlehsips after WWII, and battleships were decommissioned and recommissioned twice during the Cold War. The last time two battleships ever fired at one another was the Battle of Surigao Strait 74 years ago.

"recreational scientific activity"
Sure, in the same way that when I trust my kid to a daycare, I have to accept that there are risks that my kid may die horribly.

But the same is true when I trust my kid to myself; its a fact of life. Things can happen. It’s not like I can stop a car from running my kid down in every possible scenario, even if I’m naturally more careful and self-sacrificing than a paid stranger would be.

But that’s not a particularly insightful fact, and that certainly doesn’t excuse fault/misbehavior.

It’s not a useful sentiment to express in general, and unless you’re trying to argue for not trusting in strangers at all, I’m not sure what useful conclusion you’re trying to reach.
It's absurd that there aren't more steps being taken.

Just this morning I had 4 calls between 5 and 8:00, and I can't turn my phone off. (On-call for work.)

Our government is busy shutting itself down over nonsense, yet pathological problems that are meaningfully impacting citizens are going entirely unmanaged for years. (To the FCC's credit, STIR/SHAKEN is a good step but I think it's very much a too-little-too-late situation; I haven't been able to empty my voicemail box in years lest it get filled up again within a day by spam.)

To make this not just be a rant (and since I see others who are concretely affected in similar ways) Shouldn't we be pursuing our govts/reps to be more aggressive in everything from investigating and prosecuting violations (spammers) to ensuring proper incentives for carriers to help defend against this? Is there anyone who has been a champion for this in the past?

It's not just that, it's also pharmaceutical drugs. As far as I know, I'm the only one to ever try to come up for an estimate of total deaths from all drugs, and people (including on HN) complained quite a lot about it.
The drug approach is pushed by the pharma industry of course, exploiting the natural appeal of the idea that one can just take a pill to fix a problem that is as complicated as addiction.

Doctors prescribe these because they (probably rightly) believe not that the drugs are harmless, but that the side effects of the drug are less harmful than the direct effects of continuing to smoke.

Really quitting takes either a major motivating scare like a cancer diagnosis (for some people even that isn't enough) or a very determined decision to stop.
Although the new ad campaign may not make good business sense (if you want to continue selling to all people, assholes included) it doesn't make the message any less poignant.

In my experience, most men don't truly understand the meaning of the phrase "boys will be boys", which appears to be central in most people's criticism of the ad. (I certainly didn't understand its meaning for a long time as it's cleverly phrased to seem like a truism.) It should be taken as an insulting excuse, rather than something that should be upheld. It's saying that when a man does something gross, immature, disgusting, insulting, etc. like objectifying women or physically fighting to solve their differences or bullying those who are different than themselves, that's just the way men are and there's nothing that can be done about it. All men act like barbarians. That's what "boys will be boys" means. It's saying that no man is able to control or overcome their basest instincts.

I can't speak for anyone else, but I find "boys will be boys" to be undefendable.
Or you could have a friend buy it then reimburse them. Or buy and swap a few times to see if it affects the results. Would be easier to test the theory if it wasn’t so expensive.

These tests aren't a measure of ancestors, it's a measure of a person's DNA and where that DNA possibly comes from.

Theoretically, they are similar, but since you inherit a random 50% of DNA from both parents, on an individual scale, you might inherit a misleading percent from your ancestors.

Let's say 3 of your grandparents are all full-blooded Italian. Like, their families have been in the same village for centuries. And one of your grandparents is from England (and is similarly from an old family in a small village).

So, theoretically your DNA results should 75% from that region of Italy and 25% from English region.

However, lets say from your mom, the parent who is 50% English and 50% Italian, you only inherit a mix of 15% Italian and 35% English (15% + 35% = 50% mom's DNA). It's random, so this is possible, especially on a small sample of ONE person.

And from your Dad, who is 100% Italian, you obviously inherit 50% of your DNA as from that Italian region.

Now, you theoretically should be 75% Italian and 25% English, but since it's random, your true DNA reads as only 65% Italian and 35% English.

This is why it's mostly bullshit to me. It's impossible to know what percents your DNA randomly passed on to your ancestors.

Sure, in our example, the two places where correct, Italy and England, but the percents are way off.

And that's honestly WHY we get these tests. We generally know where our families come from, we just have no idea what the percents are.

So, the whole point of the service is stupid since they equate DNA with ancestry.
