I might have missed it, but doesn't look like ketone levels was one of the factors being measured. You can actually buy ketone pee strips at any drugstore for cheap. Would have been an interesting thing to track, since conventional wisdom says that ketosis is binary, you're in it or your not, and the actual ketone level doesn't affect the weight loss. I'm sure this has been put to the test in some experiments already, but maybe applying learning could teach us more and validate/invalidate this hypothesis

You learn the controls in about 11s after buying it, there's only about 8 of them. As for the rest, the guy in the video just gets it all wrong. Getting in with dead battery is explained in handbook btw. etc etc.

The bonnet was split as the bolted down one was only lifted for service - all fluids, day to day maintenance could be done via the little one. Silly idea I agree though - everyone who buys one wants to look at the nice 4l straight six that makes the nice noises!

I might suggest that Wave and Vista are obvious projects Google and Microsoft wrote and below a standard of quality, and akin to a bad movie from WB. Google+ and Windows 8 could be considered bad sequels.
No one's arguing that they shouldn't have that leeway and ability.

They're saying it's shitty that people on the bottom get punished as a result of risks taken because of that leeway.
Many die. Are you surprised from watching the videos that it's dangerous?

One of my favorite climbers and free soloists, Dan Osman, also died in an accident but not while free soloing. He was doing a 1000 ft rope jump (jumping from a cliff while connected to a climbing rope and catching oneself while trying not to slam back into the cliff face) when his rope snapped.

Here's two videos of him doing a rope jump and of him free soloing:

Fuck around or fuck up, and your compensation is only hit with a pillow. And people make excuses for how you failed at your responsibilities. Sounds nice.

If CEOs are afraid to take necessary risks because of consequences, they suck at their jobs as leaders and should be fired. CEOs need to know what they're doing, they shouldn't be given a lower bar to clear than everyone else. That they do is mindboggling.
I understand that much, but, as I said in my comment, that would only work if the partial match were informative about the full match. A partial password match is informative of what the full password is, but a partial hash collision is not informative about the full collision. By design, learning about one hash preimage tells you nothing about other hash preimages.

By contrast, if you were comparing my submitted password to a stored password, I could use your response time to know that I got the first n characters right. Since n is a prefix of the password, I've learned something about the password, I can lock down those characters, and then guess more, etc. That much I understand.

But the case you're talking about is a comparison of hashes. In that case, timing attacks can tell me that my guess's hash's first n characters match the password's hash's first n characters. So now what? How do I adapt future guesses to learn more characters? What have I learned about (a preimage of the hash of) the password?

If partial hash collisions were, in any way, helpful in guessing the full collision, Bitcoin mining algorithms would adaptively change their guesses as they discovered that their nonces only led to a partial match.
Anonymity for free expression is the only solution to prevent any of these social 'big data' problems. Tieing real ID to human data is not just bad for people. It is bad for business. Ad tech relies on a user base that doesn't filter themselves or find means to circumvent tracking.
I was in Ketosis for 12 months, and the last 6 months was training for my first Ironman (age 37).

I would say most of the benefit from Ketosis while training is the recovery. I had plenty of energy for my long rides, but the lower inflammation was making recovery quicker.

My race was cancelled (Tahoe) and I went to Spain two weeks later and did Barcelona instead.. 10h and 3 minutes. Pretty happy with sub-5h for the bike leg!
But what's interesting is that TV is having such a different trajectory (TV as in video packaged as episodes, the lines have blurred). Netflix and the like.

I often wonder if TV is winning because it has built-in sequels. If a series doesn't stick, whatever, money lost. If a new series does well, you can milk it for many many more seasons. TV vs Movies, the risk in cost is the same but the upside is much higher for TV.
Do you have a name/link for the "reputable" vendor? Just curious
My issue with places like Yelp is that people could post a negative review for the silliest of reasons and it can be hard to tell if the restaurant actually messed up or the person had different tastes than me, crazy expectations, or caused the problems themselves. I just don't trust them. If I had, I would never have discovered and repeatedly enjoyed some of my favourite restaurants.

For something like a contractor working on your house, yea it's important to see those reviews. For a meal? I'd rather just take a chance based on a lot of people saying they had a good time. It's what you do anyway when you check out a new restaurant based on a friend's recommendation or just on a whim.

And the whole point is not to have any star system, you either liked it or loved it and that's it. No opportunity for commentary so if you want to complain, go elsewhere. The tagline I dreamed up was "Haters gonna hate, eaters gonna eat."
The rate of glycogen synthesis is directly mediated by glucose availability, and the glycogen synthase enzyme is also activated by an insulin induced signalling cascade. Glycogen replenishment still occurs on a low carb diet, it just takes longer.

If you only do crossfit every 2-3 days, and rotate the exercises you do somewhat (as is typical at most boxes) you might not notice a big difference between a low carb and higher carb diet. If you train daily and you're doing similar movements every day, you will definitely notice a difference. Since that is pretty much the modus operandi of serious athletes, that is where the whole "athletes don't do well on keto" idea comes from; it definitely doesn't apply to your garden variety recreational athlete though.
Your link (3) is deeply troubling. It claims to be "synthetic emerald spinel". Emerald is beryl, not spinel. It claims to have a hardness of 9. That would make it corundum; neither beryl nor spinel is that hard. I'd really rather buy gems from a source that can describe them without contradicting itself in multiple different ways.
> Without a thick atmosphere, any burgeoning life would have to deal with random bursts of energy that could cause damage to that lifes equivalent of genetic coding.

Is having a thick atmosphere a necessary condition for life?

Is it not possible for a mutation to result in a 'thick skinned' life form - one that relies on its exo-skeleton/skin to withstand the drastic changes? Or a color-changing 'plant' that evolved to do ultra-fast-photo synthesis when needed and move into a dormant mode, when not?

Such a thing would allow such plants and animals to move out of the seas and go onto dominate the land.
(Assuming, of course that there is life underwater)

Diamond (the material) has lots of uses. As Neal Stephenson points out in "The Diamond Age," if you can make diamond cheaply, you can make large thin-shelled dirigibles out of it that become lighter than air when you evacuate a little air out of them. Diamond is the only material strong enough to make this possible.

I'll take that as a no. Your title claims "All of Andrew Ng's machine learning class in Python." I think you've sufficiently admitted this is the course work, and I need to point no further than that. Now you also fall back and say, "Well, other people are doing it too!!" which is itself an admission of guilt in my mind.

The way I see it, Andrew Ng is an entrepreneur co-founder with a startup called Coursera. He makes his courses free, because he's a good guy, and free attracts the audience that makes his platform worth something. By reproducing one of his most popular courses in python, you dilute his brand and try to snatch part of his audience.

It's not any different than if you copied Harry Potter wholesale, but translated it to French. You're infringing on a work a person with noble goals produced, and who is head and shoulders above you as an authority on the course material. It's fine to be excited about what he taught you, but you should make your own course instead of gimping his.

Don't be the reason we can't have nice things.

Huh. So banks really couldn't use event sourcing could they? Oh maybe they could so long as every failure was a new event.
Thanks so much for all the excellent comments. There was definitely an over-fit with 4-passes.

No more. I've updated the Makefile to run only one pass, changed the options so it runs with older-version vw, Fixed misspellings of 'gioza', removed 'mayo' which found itself on the wrong side because it appeared only twice and always alongside the bun and regenerated the chart.

All the main conclusions remain intact.

In the end, I urge everyone to use their own data, that was the main purpose of sharing this code. My data-set is small, awfully noisy and insufficient. There are no p-values and no rigorous statistics, so please don't read too much into the minute details. It is the discovery journey into the top factors that is the important part, in my view. The ML was just one aid in this discovery process. The proof for me was my actual, and sustainable, weight loss that came after (very slowly) realizing the top factors that eventually worked for me. Thanks again.
I am very interested as well and hope there is a response. Since he was working with an MD, my guess is as follows: insulin is the devil.

Whereas if you look at the old FDA food pyramid and the new food plate, carbs/sugars/fruits take up a significant percentage of the recommended daily diet. Take fruit for example, prevailing norm would be fruit is healthy (especially in its natural state where it is accompanied by fiber), fruit aside most people would believe carbs (especially in whole grain form) are perfectly fine in moderation. My big guess is that an M.D. recognizes any amount of carb (fruit or whole grain being no different that high fructose corn syrup) triggers the bodies production of insulin. More and more, I think M.D.'s will have negative perspective on any/all insulin production if it can be avoided. I have more thoughts on the impacts of insulin on the body, but I hope OP will chime in with a response to see if my instincts are on point.
It all depends on whether investors or Google executives are better allocators of capital.

You seem like you might be knowledgable here, so I'll ask this one here.

Is Arxiv considered a Peer Reviewed Journal or is it Cornell's submission database?

Their site really doesn't allude one way or the other so it makes me think its just a database.
yeah, all of those buts and ifs make the analysis not statistically significant. It's not a random sample and asking people whether they are depressed is not meaningul, Depression is a disease that is quite distinct from simply being sad or in a melancholic mood.

I worked at a telecom company in Afghanistan a few years ago when the country was relatively safe. I'd like to leave HNer's with some statistics that are not included in the NYTimes article that might explain why it is so vital to move any part of the agricultural crop away from opium:

Afghanistan's opium production currently goes into more than 90% of heroin worldwide.

According to a UN doc cited on wikipedia, production reached a peak in 1999 with a bumper crop of 4,500 metric tons. [1] Shortly afterwards in 2000, 99% of poppy cultivation in Afghanistan was wiped out by the Taliban, who controlled Afghanistan with an iron fist and declared the cultivation of poppy "un-islamic". This amounted to a 75% reduction in the world supply of opium. So total world production was ~6,000 metric tons in 1999.

According to this 2014 UN report [2] the total area of opium poppy cultivation in Afghanistan was estimated at 224,000 hectares with an average yield of 28.7kg/hectare. Converting this to metric tons: 224,000 * 28.7 / 1,000 = 6,429 metric tons of opium produced. Report cites a possible range from 5,100-7,800 metric tons produced.

So not only is Afghanistan back to pre-Taliban production levels, it is producing more than the entire world production of opium in 1999. This is just 15 years after a 99% eradication of the crop in the region. Ironically, opium production has ramped up massively since 2002, under US/Karzai governance.

The farm gate value of this opium is only $850m. Using an average of the conversion ratios cited in the report (18.5:1 for pure heroin, 9.6:1 for export-grade heroin) and a price of $60,000USD/kg of heroin [3] we get a total processed value of $27.4bn. That's a crazy amount of value locked into processing and distribution.

Any amount of possible change towards other crops will be hugely beneficial for smaller-scale farmers who do not wish (or do not have the connections) to sell into the drug trade, and who only see 1/30th of the processed value of their crop. Not to mention it will be putting a dent in the world supply of heroin.

This is an ambitious and well-intentioned project. I'm glad to see HN sponsoring these types of ventures, especially as it falls outside the scope of the tech world and does not have the TAM/SAM/SOM projections that I'm sure VCs dream about. Good luck to the founding team, and stay safe.

You will see greater endurance adaptations in response to exercise in the short term on a ketogenic diet, though this effect decreases the longer you maintain the diet. The downside to a ketogenic diet is your total training volume for work above the lactate threshold is more limited.

As a result, high level athletes tend to spend the majority of their time consuming a carb-rich diet, then switch to a ketogenic diet for 2-3 weeks prior to competition. During this low carb period, they just focus on a very high volume of low/moderate intensity work. Finally, 2-3 days before competition, they will carb-load to glycogen super-compensate, getting the best of both worlds.
To put it in perspective, a recent research study[1] conducted by a team of elite PhD economics researchers discovered the astonishing fact that people who face a sudden unexpected financial crisis (such as medical bills, car breakdown, job loss) are surprisingly less likely to become homeless if they can pay their rent/mortgage, while those who cannot pay for their home are more likely to become homeless.

(In truth, they went in-depth in calculating percentages and timelines and cost-benefits, etc. That summary trivializes their work.) But the basics of this discovery made by this elite team of academic researchers is something that every single working-class person in the country, even high school dropouts, knows as a simple basic fact of everyday daily life.

The idea that you would need to educate and train several people for many years, to the level of being professors at top colleges, then assemble a team and give them a grant to do a study to discover such a common part of daily life seems a bit ridiculous to non-academics.

To be fair, they're fake in one sense: very often they're sold as something else than their description suggests. In other words, the label usually says "diamonds from mine X".
ArXiv is certainly not a peer-reviewed journal. There is some basic review (https://arxiv.org/help/moderation) and an endorsement system (https://arxiv.org/help/endorsement), other than that you can freely submit content there.

That speaks to a lack of innovation though. Obviously Google shouldn't be trying to build a carbon copy—but they seem to be incapable of building anything besides that.

Plenty of startups have arisen to challenge Facebook (Instagram, Snapchat, WhatsApp). Why didn't Google build any of them? Especially when so many startups are founded by ex-Google engineers.
Woah!

I thought I might be over-doing it with 2 DXA scans :)

I should dig mine up, I got down to 10% body fat a few weeks before completing my first Ironman. I'm normally around 17-19% from memory.
A percentage of their pay? While people further down the line lose all of their pay without having significant say? Questionable.
I overheard someone talking about there being timed strings outputted to the serial lines on the badge (And the TX, RX and GRND pins were not together) but take that as conjecture and I was too shit/lazy to check while there, so unconfirmed here.

I'm surprised that solving the badge didn't utilise anything that was in the badge.
The road utilization has increased as well as the fuel usage for the driving between passenger drop offs and pickups. As well as the commute of the Lyft driver. That said, if it causes people to take the train the next 25 miles into the city as opposed to driving it could actually decrease.

The comment above, which you're referring to, starts with this:

> Source is a basic understanding of containers and a basic understanding of databases.
>
> a) Docker and other container systems are still very young. ...

So it's seems to be meant to be about container systems in general, although it then talks about Docker as if it was a representative example (which it isn't).

FWIW I see nothing wrong with using containers (even Docker) for databases. Of course, it depends on what you expect from that - it may for example make automated deployment much easier, etc.
It's more than just 'I have a hunch' - I'm sure there are studies that show depressed people prefer darker colors. For example I found this after a quick search for "colors and depression"[0] and there are many more like it. Why wouldn't that carry over to Instagram too?

Oh wait...
Have to disagree and vote for nuts and cheese.

I've never been really overweight, but still, even the slight problem I had is gone with the change of some eating habits. Mostly, a lot less carbs - I really don't need a bakery and I have to tell the Thai or Chinese waiter that I need only 10% of that huge load of rice (they always pack more rice than the rest - which already is a large amount).

Next to zero extra sugar (outside food items like fruit), no cake, no cookies. I don't need to, zero appetite for any of it. I don't even touch that honey jar in the corner any more. This is great for my teeth! (also according to the dentist, no sugar - no cavities, general rule). Always had trouble, now non, zero, with much less brushing.

I eat very high amounts of nut cream, which is just nuts but crushed to cream, expensive stuff but soooo tasty. A slice of toast, than add almost 1/3 jar of nut cream (mixed and/or cashew and/or almond white/brown and/or hazelnut) - so, really a lot - add quark (https://en.wikipedia.org/wiki/Quark_%28dairy_product%29) and some (not too much) fresh fruit and some non-crushed nuts from varieties that I don't have as cream, like walnuts.

No problem at all with my weight, unlike years ago when I really had to watch myself and did a lot of sports and running, so it's not like I can eat anything I want.

Same with cheese, but it's very little hard cheese, and all of it is high quality. A lot of my cheese is from sheep and goats.

Lots of veggies - but always with some meat. Can't eat as much as I used to any more though, my body has settled on wanting only a little bit of it.

Also, I found it important to NOT cut the (easy) carbs completely! Some white bread or rice etc. is absolutely necessary. It's just not very much, not even a full slice of white bread for the nut breakfast, for example. I think the diet that tries to brute force you into eating nothing at all of that kind of food is too extreme.

I can't eat a lot of whole nuts though, only the cream works. Which is just mechanically different, there are zero add-ons in my (organic) nut cream purchases.

Oh and I get plenty of sleep too, I don't use an alarm clock. Advantage of working from home.
