Assuming your goal is to be a better chess player (reaching expert/master level or up), the answer is no. Grandmasters typically charge exorbitant price (at least $50/hour, I recall that Lev can charge $300/hour), but the main problem is that unless they have so much experience teaching chess, they won't understand why amateurs struggle at certain positions (since they get such idea effortlessly). The rule of thumb for choosing a coach is picking someone about 400 points higher than you (either USCF or FIDE works), who has gone through similar struggles and practices to get to that level. Honestly, getting GM coach only worths the money when you are 2200 and up.

Disclaimer: never have a personal coach before. Did play for a while in a chess club where the team leader is about 2200 FIDE.
What is Village Capital? Is this another bootcamp? Seems like quite a few have gone under recently.
There is a limited supply of U.S. dollars in a country like Vietnam, which naturally limits its use in illicit trade. Both paper money and cryptocurrencies have to be converted into "clean" money that can be deposited into banks to pay taxes and expenses. While paper money requires expensive and potentially dangerous laundering operations lest you end up with warehouses full of bills, you can hold crypocurrencies in a wallet for no cost until its needed to be laundered and exchanged for real income.
While the idea that "polynomial time is fast and exponential time is slow" is quite popular, it's important to realize that those are descriptions of the growth in computation time for ever larger input sizes.

In practice, you are usually only interested in a limited range of inputs, for which an exponential time algorithm may turn out to be faster. If you really want the fastest algorithm, you need to actually measure the runtime on realistic data.
My question is more of how many shallow neural networks are still in use. The deep in deep learning is typically much greater than three.

Right. There absolutely is a bubble in tech right now, but it's a much much smaller part of the total tech industry than it was in 2000. Legitimate valuation of tech is now in the trillions, and well earned. Tech will never crash to the degree that it did in 2000. A lot of people might end up without jobs, but it's not going to cause a huge recession the way the dot com bust did.

Well, you can just as well be best friends, even if you're wanting to mold each other. Both parties just have to be open-minded about it.

You might even see it as positive to be challenged in your ways, as it helps you to move yourself forward. For example, if you're a couch potato, you might actively look for a sporty partner in hope of being motivated to do sports.

Your point isn't without merit but a little overstated. A couple of points:

> Microsoft was sporting a ~50-65 PE ratio in 1999/2000.

Today's PEs:

MSFT: 28.35
GOOG: 34.74
AAPL: 18.55
FB: 38.64
CSCO: 18.08
ORCL: 22.18
T: 16.33
VZ: 12.54
CMCSA: 17.56
INTC: 15.56

As you say there are some outliers too:

NVDA: 57.80
TSLA: --
AMZN: 277.89
NFLX: 201.87

Now I went through a list of the largest tech companies to produce the above list. What this seems to show is that the sector as a whole isn't overvaluaed, at least in terms of earnings.

As for the outliers, they're all pretty much examples of large bets on the future of the various companies:

- Nvidia seems to be well placed for GPU driven ML

- Tesla is a bet on battery tech and self-driving cars

- Netflix is a bet on Netflix dominated global on-demand entertainment and distribution (they're now in all but 4 countries)

- Amazon is of course a bet on owning the online retail sector

Like any bet some will pay off and some won't.

> This list only keeps going.

See now that's a bit of a stretch.
The argument falls flat for me due to the assumption that one only participates in the "marriage market" OR the "sex market".

Seems a false dichotomy, not backed by data,and the rest of the argument depends on it.
While you're right that if they had built something with "high utility value", they could have succeeded despite these points, for a pure gimmick that anyone would have only bought ought of curiosity, they failed to capitalise on the sales they could have made in the early period of significant media attention they got.
Gimmicks like that (tamagotchi, fidget spinner, yoyo) have a limited shelf life. That's kind of the genius of many Kickstarters... Gimmicks that noone would buy after careful consideration can sell a decent number of units at "peak hype".
My general theory is that:

P(Success) is highly correlated with (Marginal Value / Marginal Cost)

The original Snapchat app succeeded because the marginal cost is low (everyone already has a smartphone) and it provides a good marginal value to a subset of population (over other social networks).

Spectacles carry higher monetary and more importantly convenience and social costs to use and add little extra value beyond existing solutions.

The same framework could be applied to Uber, AirBnb, ... as well as many startup failures. Note that P(Success) or probability of success implies that there are factors other than those included in the model.

I’d love to have refinements or counterexamples to the model if anyone is interested.
Am I the only one that thinks that a) it's obvious that these sorts of devices (face wearables) aren't led by people who have worn glasses their whole life and b) if you haven't lived that, you shouldn't try to build devices for people's faces?

I say it's obvious because neither Glass nor Spectacles were wearable by people who need corrective lenses AS corrective eyewear.

None of the leadership had any idea what it meant to have a large piece of hardware on your face all day every day. Nor, importantly, how to convince someone to put a large piece of hardware in their face every day all day.

It's like they didn't even BOTHER to call the guys at warby Parker, or zenni, or even the anti-christ Luxotica

Glasses are SO much more personal than a computer or a phone, or even a shirt or other clothing. They are your face. Your literal identity.

It's so tone deaf of both teams (and everyone in the AR/VR community that thinks some manner of out-in-public eyewear is "close) to not deal with that need for customization at minimum.

Sorry had to rant about that. M sure all those people are actually pretty sharp, and I'm just being grumpy.
After some digging, it is "Mathematical Recreations: A Subway Named Turing", Scientific American (September): 104,106-107 by Ian Steward which can be read at http://dev.whydomath.org/Reading_Room_Material/ian_stewart/C... (the key memory points that confirms it is the conversational mode and the passage "And I swear there's a sign just along the tunnel that reads 'flip-flop 7743A/91.'"

Though A.K. Dewdney did write on a similar topic - Dewdney, A. K. 1987. Algopuzzles: wherein trains of thought follow algorithmic tracks to solutions. Scientific American 256(6):128–130.

> In Sweden this is effectively the only way you can make the "stack ranking": you move a bunch of workers to a special branch or factory.

Stack ranking is one of the worst ideas to ever hit the corporate world, and is, in general, a sign that I probably don't want to work (as an employee, at any rate) for that organization.

Collaboration is so fundamental to software development, or any creative endeavor.

Stack ranking, however, encourages heavy amounts of back-stabbing political competition.

Even if the team performs well ahead of expectations, the bottom 20% of the team will still face consequences for the "underperformance".

This is the same sort of bullshit that killed Sears.
How would that help in this situation? The attacker had a database of user/password pairs they were trying; they weren't trying to brute-force a particular account.

This is sound advice. I did have chess coaches when younger. I reached 2100 at 17 but stopped playing shortly after to focus on school and other things (competitive chess play and study is extremely time consuming). Even when I was 1900ish my coach was only about 100-200 points stronger than me, but it worked out great. It's all about getting you yourself to put in the work. To identify your weaknesses and shore them up. Think of it like a personal trainer. Getting an old GM as a coach would be like getting Arnold Swarzenegger as your person trainer.

> we believe will force anyone trying to block our traffic to end up blocking large areas of the internet--such as every server being hosted on Amazon Web Services--which would cause a serious problem for Chinese business people, deeply affecting commerce, as well as quality of life for the average Chinese citizen.

Not really. China has several replacement solutions for AWS. Ali Cloud, Baidu Cloud, etc.

It would just mean blocking a few more websites hosted on AWS and used by Chinese people, GitHub maybe? Then again, it is easy to build a GitHub clone within China with the decentralized (irony much?) git protocol.
It's not a stretch, the list of companies whose valuations have dramatically increased with between zero and very little growth, is a long one.

That's the part where the market has kicked into bubble valuation territory, when you're primarily seeing multiple expansion driving 40% or 100% type gains.

Microsoft hasn't been able to grow earnings for years. Why do they have a 30 style PE ratio? Why did their stock triple on zero earnings growth? Comparing their growth today versus the multiple, against 2000's valuation, today's value proposition is drastically worse. Or spread it out, compare 1995-2000 MSFT growth, with the multiple they had at the end of that five years, versus 2012-2017 growth and the multiple they have now.
Testing before release is too late. They need to create a dummy mock-up and try it out while they are still brainstorming. If they did that, and were thinking clearly, I expect they would be able to think of a lot of the problems in this thread.

I get that, but in that case you could lay the blame with apple's security policy. Why did they allow a non employee in with a smartphone and tempt fate?!
> So you do like “obscure statistics” after all! Good!

No, I just don't like people claiming a bunch of truths, with no data to back it up.

Also, don't dump a bunch of propaganda on me and expect me to dig through it looking to verify your claims.

Show me where in that does it say that the average smoker is "impoverished". Or that a majority of smokers around the world don't like to smoke, and are doing it simply because they are addicted.
Net migration means people moving back are offset. Yes, the rate is not insane and it's not simply based on IQ or anything, but it's also not a random process. Presumably, the people with the best US prospects are more likely to stay.

As to 10% figure, I am simply making the point that each year adds up. 75k per year might not seem huge, but you hit 1.5 million in 20 years. And again that's just the US, the brain drain is cumulative across all countries people are migrating to.
Cleansing of the Temple – “within a week of this incident, Jesus is dead”
We have not added support for this yet but there is no reason why it shouldn't be possible. Generally, the serialized objects can be synchronized into the browser's indexdb (we use pouchdb in the background so this is pretty straightforward) and together with a service worker and some caching this is doable.
Corporate lobbying is more than just organizing to 'be heard'.

It's a sophisticated and entrenched patronage system that involves party donations, individual donations, favours, junkets, nepotism, revolving doors and more.

Comcast, Mylan, Oxycontin, Monsanto, the current FCC chair just a few egregious recent examples, taking decisions against public interest even in the face of strong vocal resistance from the public so calling won't help. Lobbyists are a major portion of the Washington political establishment.
This problem has been on my mind for some time now.

Requiring some kind of unique identifier seems like a difficult thing to sell to users, but otherwise we may be at the mercy of bots.

And it's not the scammers and normal spammers using bots that worries me. It's the potential to shepherd public opinion on social networks.

I'd really like to see a comparison to TOR. Because honestly, from randomly clicking through the website I don't see why you're better than TOR and why I should use ORCHID.

I cannot (easily) find answers to pretty much every question I have, and sorry, I'm not going to read through a 50 page whitepaper before I decide if it's worth it.

What is it, onion routing? There's some talk of ethereum, so presumably you can get eth for spending traffic? Exit nodes? hidden services? (I'm not going to run an exit node for obvious reasons)

Sure. That's exactly what's happening right now (in the Fox News/Breitbart/The_Donald parallel universe)
On the viability of consumer SaaS
Dear HN,

I have read many people strongly advice against working on consumer SaaS e.g. patio11. The main argument seems to be that companies are way more likely to open up their wallets than consumers. The other argument is that it is easier to get companies to pay up big amounts of money, so that you can get more profit from each customer. That makes marketing easier, because you need less people going through your funnel to get a reasonable amount of income. Finally, companies are less prone to churn. In spite of all of these issues, I am working away very hard at a consumer SaaS app.

Why I am working on a consumer SaaS app?

- I am building a product I want/need for myself, which turns out to be for consumers.

- I am very passionate about my product idea/industry. I could see myself dedicating the next decade or longer on working on this field/idea.

- I think know my market very well.

- I believe I have some good ideas to overcome the marketing hurdle.

What is my project/idea?

I am developing Koipun Reader (koipun.com). Koipun Reader guides you through consuming native materials in steps so that you can reach advanced Japanese.

My goal is to make a 100k a year salary for myself and work on an idea I love.

I dedicate around 50% of my time to Koipun, the rest of the time going to a project that actually pays the bills. Am I stupid to invest a massive time amount of time and energy on a consumer SaaS product? Should I instead work on some B2B idea? Is consumer SaaS viable? Any advice for me?

I am 29 years old and I am dedicating my heart and soul to this project. Above all, I want to be independent while working on something I love. I can not bear the thought of not being my own boss and getting the freedom that comes with being an entrepreneur.

> As such, Bitcoin and other similar virtual currencies are not legal means of payment in Vietnam.

How can you make a means of payment illegal? Is bartering illegal, or do I have to use cash or checks? I don't understand how you can legally block the use of a cryptocurrency without ruling these out.
> HN/Reddit being aggregators isn't relevant to my point - I derive value from these sites and browse to them directly. If your site was that valuable, people would do the same. Besides, much news in newspapers is also just aggregations of AP/Reuters stories.

It is exactly relevant to your point. You don't derive value from those sites, you derive value from the content those sites link to.

AP/Reuters are also aggregators, they pull stories written elsewhere into a feed that publishers can use.

At some point, somewhere underneath this pile of aggregation, someone needs to actually do some journalism. And get paid for it.

@averagewall already explained what depth 3 is.

The explanation of poly time is a little bit lengthier. Let me briefly explain the PAC learning paradigm in the context of this paper.

Consider the set of all depth 3 neural networks with n dimensional input and k dimensional hidden layer whose weights have total norm 1. Let this set be called H. Note that this is a well defined set, parameterized by the weights of the neural networks.

Let ∊ be an arbitrary positive error value and let δ be an arbitrary prob value. We are interested in ∊ ≈ 0 and δ ≈ 0. The solution of the PAC learning problem is an algorithm, say A, which takes a dataset D as input, generated from a dsitribution Π, and which runs in time that is polynomial in the size of D, and spits out a specific neural network h that lies in H. Furthermore, no matter what Π was, the probability that the neural net h, that A produced, has error that is at max ∊ above the optimal error achievable by any member of H, should be more than 1-δ. This is the PAC learning paradigm.

The paper assumes that Π is a distribution over the n-dimensional unit sphere, so all examples have the same euclidean norm and constrains the weight vectors to have unit norm, AND WITH THESE ASSUMPTIONS, it gives a algorithm that requires |D| = poly(n, k, 1/∊) and runs in time poly(D).

Something that is not to underestimate is the amount of work it takes to support various kinds of content and programming languages nicely in this form. To get the most from it you want some kind of runtime integration to get feedback (errors completion) or at least good type system support integrated. It's interesting to watch a project like Atom grow – the plugin system they have is nice but ultimately the kinds of interaction they support with it are only text based. I think, in order to have a Smalltalk-like IDE take off, one needs to have similar support for extensions while allowing those to be easily integrated with richer tools like inspectors and debuggers.
