a_d··on The US is the most expensive nation in which to have a baby
In India, there are small boutique hospitals that solve this very problem (e.g. https://www.cloudninecare.com/; https://www.motherhoodindia.com/; http://ovumhospitals.com/ and hundreds more in every city). I have always been so surprised by how "broken" maternity is in the U.S. and just how overtly "scammy" some of the things are e.g. if one needed breast-pumps, there is a 'company representative' that would deliver it to your hospital room and you get charged separately - by the company - and nurses get a kick-back; There is a nexus of private practitioners roaming the hospital wards helping mom's with early care - most of them looking for 'repeat business', after one is discharged. This is from experience in San Francisco. Not to mention the 'baby-product-industrial-complex' where one is convinced that highly special, safe and pink or blue colored equipment is needed for baby care. So there is a LOT of money made in the U.S. from every birth by a vast nexus of companies. Just the product choices one is forced to make drives millions of panicked google searches a year (with 'listicle-focused-SEO-hog-blogs' feeding off of this) -- just to search for the "right" equipment. Why can't just one company consolidate this -- and offer a one-stop-solution? Naked Capitalism is on its full-show during the birth process in America. It is indeed very strange.

Finland has 'baby boxes' delivered by the govt: http://www.bbc.com/news/magazine-22751415

Sweden has a govt sponsored program for end-to-end support for new parents: https://sweden.se/society/10-things-that-make-sweden-family-...

The reason for this comment is that HN has a 'startup' bent to it, so I hope some entrepreneur just Warby-Parkers (is it a verb?) the baby birth process. There is definitely room for massive simplification. Make each decision simple -- that alone is a giant opportunity.

a_d··on Don't get caught up in blockchain hype
So, umm, what is blockchain really useful for? The basic thing blockchain helps with is: it provides a way to verify the order in which entries are made to a ledger.

Genuine question: What applications/problems it is useful for? Have you seen a good application yet (other than currencies)?

Would love to learn about the positives, from this community.

a_d··on Investing in ICOs May Be Even Riskier Than You Realize
There are so many articles about ICOs that don't offer any new thinking. This one covers:

1. Lots of ICOs happening (crossed $3B in money raised).

2. ICOs are risky.

3. SEC will likely use the Howey test to determine which ones are securities (and therefore need to comply with securities law)

4. Startups may be able to protect themselves by limiting token sales to accredited investors and providing more disclosures in their white papers. (a hack that most people now are well aware of -- i.e. the utility token + SAFT route)

5. When you invest in an ICO, you not just take financial risk, but also may inadvertently be breaking a law (basically, ICOs are fraught with uncertainty)

I wish we heard something new. Clearly, there is something interesting happening - a new way to raise money, or perhaps a new way to launch products. In the long run, it is exciting because it will help launch useful products and services. But many articles often just regurgitate what most people already know, and don't offer anything new.

I suppose regulatory authorities at some point will offer a way forward (by regulating this space -- which I think would be a good thing!). Until that happens, we just hear a lot of armchair thinkers and potential practitioners just conjecture endlessly.

a_d··on Google just released its internal tool to collaborate on AI
Questionable usefulness aside, technically, I think it is a very cool feature! :)

(Roughly speaking: IPython + Gdrive = Colaboratory)

a_d··on “One Damn Slide After Another”: PowerPoint at Every Occasion for Speech (2016)
I am surprised there isn’t more on this in this thread:

Persuasion is the center-piece of business activity.

One of the most powerful ways to persuade is through storytelling. Well storytelling is central to our social and cultural experience. No wonder that it finds its way in our work — esp work at big companies (more humans = more social, cultural). Most presentations, discussions or meetings are exercises in persuasion via storytelling.

For years stories are told with theatrics or embellishment. That’s PowerPoint.

In the hands of a good storyteller — someone who has something to say and a compelling way to say it — PowerPoint will seem like a great tool. Conversely, the tool will suck (in the same way a guitar sucks when i play it, but becomes magical in the hands of jimmy page :))

Now, as a storytelling tool — just the fact that PowerPoint has found its way into a Billion computers — is astounding. Probably makes it one of the most useful tools invented!

a_d··on Ask HN: What are top promising technologies of tomorrow must get involved today?
Robotics, but more specifically Tele operated robots. Remotely driven vehicles and remotely controlled robots.

There is a chance that all factory work becomes like a video game.

Tele-ops robotics would lead to:

- large-scale redistribution of physical/blue-collar jobs (bigger than "software" over last 20 years)

- allow new business models that were never possible in manufacturing (e.g. robots for "rent" - subscription model, gamification, flex-work like Uber for tele-operated robots in manufacturing; low-volume sales)

- order of magnitude better physical health of workers (lower injuries, more fun)

- savings for manufacturers (not just on labor, but lower insurance etc.)

- a 20 to 30 year hedge against the invention of general AI that seems far away and what other roboticists are chasing.

There is a potential to release huge latent wealth by creating a new industry (potentially trillions in value could be released over the next 10 years - no single company would capture it, but it would create something at least as big as "software").

Tele-ops is already successful for surgeries and dangerous situations. But it should be it’s own “field”

a_d··on Joseph Campbell’s daily routine for “the most important period of my study”
Sounds interesting. How would one build it for 'influence'? E.g. I would imagine it to be vast and utterly fascinating to map the influence graph of Tarantino :)
a_d··on Joseph Campbell’s daily routine for “the most important period of my study”
My first impression of Taste.io is very positive. Good recommendation! Thanks.
a_d··on Joseph Campbell’s daily routine for “the most important period of my study”
Key passage: "When you find a writer who really is saying something to you, read everything that writer has written and you will get more education and depth of understanding out of that than reading a scrap here and a scrap there and elsewhere. Then go to people who influenced that writer, or those who were related to him, and your world builds together in an organic way that is really marvelous. Whereas the way these things are taught normally in college and school is a sampler of what this one wrote and that one wrote and you’re asked to be more interested in the date of the publication of Keat’s sonnets than in what’s in them.”

I think many of us have deployed this graph in our own lives. I watch movies this way - watch more movies made by a director I like. Then watch movies by the people this director likes. Its a wonderful exploration.

I wish there was a version of IMDB that allowed this meta exploration of movies - i.e. exploring the influence-graph for movies (or any art as a matter of fact).

There is a wonderful documentary called Connections [1] that explores this in the world of science, technology and engineering -- it traces the sequence of inventions and inventors that had influenced each other. I strongly recommend viewing it. You may find it very inspiring!

a_d··on TransferWise announces $280M investment
I used to study remittance flows for a living. This was a problem that was (is?) begging to be solved. Incumbents like Western Union have always been very expensive and borderline evil. There are well known “corridors” of remittance flows that are still yet to be captured - like Kerala (India) <> Saudi Arabia (Middle-east more generally); Mexico <> US; US <> LatAm etc.

My guess is TransferWise captured the UK<> Poland corridor and expanded from there.

This problem is a great one to solve because the customers have a real pain and one can be very targeted about capturing high-value corridors.

I wish TW the best. Lower fee, Lower friction, Lesser time == Great for customers!

Anyone looking to build a startup in this domain should start here: http://www.worldbank.org/en/topic/migrationremittancesdiaspo...

(This data is useful to understand origin<>destination of remittance flows; Its a greater than $150B market and a lot of untapped/Uncaptured areas; lots still left to do!)

a_d··on Ask HN: We have a great team and capital but can't find a good idea
1. The most obvious advice in your case is to revise the heuristic you are using to rule out your ideas. My guess is that you are looking at 'who else is doing this' or some other question that leads to ruling out what you work on. Thinking hard about just that might yield a better result.

2. Instead of looking for problems, I think more about how is the world changing and what can I do about it. I would advise you to do the same. Sometimes something big changes and most people aren't paying attention. For example, Trump's recent XO on healthcare allows businesses to form "associations" (small companies can pool together to get large company rates). In the recent Berkshire meeting, Buffett said that American businesses are going to be increasingly uncompetitive (at the global stage) if healthcare costs keep rising. These are things that are connected - if one is paying attention. The uber thought is from Peter Thiel [1]

3. Instead of thinking about a startup, start an industry [2]. I think Alan Kay's talks are inspiring - but also give a good framework to think about projects.

4. If I could just give you one advice, it would be: Pay attention. Very few people are paying attention to the whats happening.

5. One of the biggest disadvantages that you have is that you already have a team and money. This puts enormous pressure to do something "Big". No good idea is going to survive this test - obvious "Big" ideas are taken (not that you still can't work on them). So when PG says, works on "projects" and don't think about starting companies - he means, just do stuff that you find fun. This is very hard to do in your case.

I have helped several companies when they found themselves in the same predicament as you did. If you think it would be helpful, I would be happy to talk: ad@42.life

Best wishes and Good luck!

To end with a cliche: Stay hungry, Stay foolish

a_d··on Ask HN: What essay/blogpost do you keep going back to reread?
http://www.paulgraham.com/startupideas.html

"The way to get startup ideas is not to try to think of startup ideas. It's to look for problems."

I personally think this is an profoundly important piece of writing.

a_d··on Ray Dillinger: If I'd Known What We Were Starting
"What else ticks me off about this, is that there is absolutely nothing wrong with issuing stock in your company as tokens on a block chain instead of through brokers on a standard exchange. Just do it legally, for Pete's sake! Go to the SEC, or whoever the appropriate regulatory authority in your jurisdiction is, and get authorization to issue stock! Hire somebody to implement shareholder voting as block chain transactions. If the law in your area doesn't allow anonymous stockholders, then you need identified participants (and, inevitably, a Trusted system to assign or match IDs). It can work. It has advantages even. But after the meltdown that the scammers are bringing down on this whole form, it's going to be anathema, or even illegal."

Ironically, the first "ICO" to do it with full compliance, useful tech and good business model, will be huge. There is demand for it.

The other big opportunity is to come up with a framework that everyone can use to be compliant (e.g. An Ethereum with "compliance" mechanisms built into it will be a big "general-purpose" blockchain).

It's hard to understand why ignore compliance, when being compliant is quite simply going to be much bigger, sustainable and "good business" than all scammers put together.

a_d··on Tell me what your company does
There are possibly a few things happening that explain this:

1. Fear of not communicating "everything" that you do. The fear is of being perceived as a very narrow solution when it does a lot more.

2. Advice that says "communicate the benefits" not "what you do". This advice could manifest itself in the wrong kind of (flowery) language. So instead of saying "export payroll reports for QuickBooks automatically" websites say "free up for time" [made up example]

3. Internal decision-making by committee.

4. Copying some website that you like - instead of thinking and reasoning from ground-up about 'what is it that I really want to say'.

5. Pretending to be a big/legit company when you are small

6. Big company with so many features that it would rather just show you the entire sales deck - the website is just there because it needs to be, but plays a tiny role in conversions. [why focus on something that doesn't add value - in this case, the website e.g. SAP.com]

This is a good article. Everyone who is running an online would benefit from thinking hard about this.

a_d··on Digital coins may be on the verge of going mainstream
Projects are issuing tokens to raise funds (ICO ~= IPO). They are of two types:

1) Protocol coins (coins that have some value within the project / product) and

2) Asset coins (coins that can be thought of as shares in a company).

Protocol coins are being positioned as presold revenue and need not necessarily conform with securities laws. Most ICOs are trying to position their coins as kickstarter-type "token gifts" (e.g. T-shirts)

Asset coins on the other hand, come under the purview of securities laws and act

People are buying these coins because of FOMO. Large majority of these projects having ICOs are scams - not too different from the dot-com bubble. Eventually, some good ideas are going to come out of these projects.

a_d··on Explaining Programming to Six-Year-Olds
Which school is this? (We are looking for a school for our kids - that's why I am curious)
a_d··on Pittsburgh Gets a Tech Makeover
PG, who grew up in Pittsburgh, gave a nice talk about how to make Pittsburgh a startup hub: https://youtu.be/CpfdtgW6_oI
a_d··on Tiny satellites ushering in a new space revolution
Unrelated and probably a stupid question -- but I am curious. What would these satellites see if they looked the other way - i.e. Outwards towards space. Would they see just darkness? Some stars? Lots of stars? Would you know?
a_d··on Ask HN: What are the best resources to learn computer vision?
Is OpenCV (traditional CV technique) better to use or Deep Learning based approach? Has anyone done a comparison of the two approaches? The obvious flaw with deep learning is that it requires large labeled data sets - but assuming that is available, which one is more accurate at object detection (hotdog or not), detecting features on an image (faces, manufacturing defects)?
a_d··on The crossover between car simulations and autonomous vehicles
What are some other use cases where simulations can help agents learn faster?
a_d··on Which GPU(s) to Get for Deep Learning
Another option is to consider something that is even more abstracted from Google Cloud, AWS or Microsoft - such as, https://www.floydhub.com/ (Heroku for Deep learning). Ultimately, someone like them may be quicker to switch between different providers than individual companies.

a_d··on Startup School 13: How to Find Product Market Fit – Peter Reinhardt [video]
Very important talk. Not sure when the phrase was popularized, but my introduction to it was in Marc Andreessen's blog post [1]. This entire series of posts in his blog are worth reading, by the way. Marc calls this "The only thing that matters", and it is definitely true.

I like this video because of the emphasis on the role our psychology plays in the search for product-market fit. Understanding people/users well - what they mean when they say "this is interesting" is really important. Systematic de-biasing of our own mind is an important idea in this talk.

Richard Feynman's famous conclusion to his report on the shuttle Challenger accident said "Nature cannot be fooled"-similarly, markets/users cannot be fooled. Either a product or service solves their problem or it doesn't. Anything in between needs to questioned carefully and observed (in an unbiased way) closely. Feynman also says "The first principle is that you must not fool yourself – and you are the easiest person to fool". Same idea as Peter's -- and a very important one!

I wish more founders talked about "what product-market fit feels like" (once they found it) - because only with enough samples, new startup founders can better understand whether they have achieved pm-fit. However, I wish video shouldn't be mistaken for thinking: "my Show HN post tanked, so I don't have pm-fit". I think it is worthwhile trying to understand what he means. It is quite clear when you really solve a problem that someone else has. It is also a great feeling.

One of the reasons why finding pm-fit is hard is because there are too many variables. Peter simplifies it to some extent when he says that while searching, one must be clear if you are changing the market or the product. This is correct, but in reality, these adjustments are quite subtle. So paying close attention to these constant/rapid adjustments (stepping back and thinking about them) is quite important.

I like the conclusion of his talk: you will know when you find it.

a_d··on The Boring Company FAQ
Maybe the explanation for glossing over some of the obvious hindrances (that you and several other commenters wisely point out) is that these projects are not conceived out of an organic need or to problem-solve issues - even though they are projected as such...but, these are projects that are born out of some (unpublished) masterplan/roadmap for learning to establish a colony on Mars.

Just learning how to build tunnels is interesting from that respect.

The reason that isn't stated is because Musk likes to create projects around a "purpose" and business plan for them to succeed (even if they are retro-fitted - that is, he decided first that it would be important to tunnel, and then arrived at the "why tunnels on earth").

edit: not a new thought. some other commenters already pointed this out. I read those after posting this.

a_d··on Robots that learn
Thanks for the explanation. Can you also explain the significance of "one-shot imitation learning" generally (beyond the context of this experiment)?
a_d··on Robots that learn
Is the vision network learning continuously or it has been trained with many configurations of the blocks and gives a continuous output?

The post says that the imitation network takes the input from the vision network and processes it to infer the intent of the task. Isn't the "intent" always "to stack"? Or can the imitation also be just re-arranging blocks in another configuration?

This part is interesting, if I understood it well.. > "But how does the imitation network know how to generalize? The network learns this from the distribution of training examples. It is trained on dozens of different tasks with thousands of demonstrations for each task. Each training example is a pair of demonstrations that perform the same task. The network is given the entirety of the first demonstration and a single observation from the second demonstration. We then use supervised learning to predict what action the demonstrator took at that observation. In order to predict the action effectively, the robot must learn how to infer the relevant portion of the task from the first demonstration."

Does this mean that the imitation network has been trained on stacking, un-stacking, throwing...and other such tasks, and then it identifies that "stacking" is what is being done in order to imitate it?

Is there an ELI5 for what the 2 NNs are actually learning?

a_d··on Alan Kay at Startup School [video]
> like the philosophy of going out into the future and bringing it back into the present. I feel like a lot of startups are making an error in failing to do this. > For example, in the not-to-distant future, we won't need parking spaces. You'll just hail the self-driving car (or similar) using your phone. People won't own their own cars.

You are right about the philosophy. But a thought regarding your specific example: even if self-driving tech were to be available tomorrow, it will take many years for all the cars (the "fleet") to be self-driving. There are about 2B cars on the road, and every year about 100M new ones are made. It would take 20 years to replace the fleet. So the "parking problem" isn't made immediately redundant with the invention of self-driving tech. There is still room (and in my opinion) worthwhile for a startup to solve the parking problem (however they attempt to solve it). Just saying that I wouldn't discourage anyone from attempting this :)

a_d··on Alan Kay at Startup School [video]
6 powerful ideas that I took away from this:

1. Live in the future: If you live in the present your ideas are going to derived from the present, and therefore will be incremental. Paul graham points to a similar idea in his essay here http://paulgraham.com/startupideas.html

2. Learn the rules and break them like pro: An important idea that says learn deeply about a field (industry or language or medium - whatever) before you go about breaking its rules. This is something that should be discussed more. On one hand, this implies that rules need to be broken carefully by understanding something very well. On the other hand, a certain "naivete" also has been proven to be successful (As he himself says in another portion of this talk). Requires more thinking... I have to say that I have worked with two geniuses who changed industries (caused a "Disruption"), but while they were "outsiders" they understood the industry they were changing very deeply, and could point to very specific flaws in them (legacy rules) that were ready to be broken.

3. Scientists and engineers working together: I love this specific idea. He points to the Manhattan project and the Radar project as successful examples (and ofcourse, Xerox PARC itself). I also understand why OpenAI is organized the way it is -- they must have taken inspiration from Alan's ideas.

4. Progress is the only important thing: This is very similar to YC's idea of have a metric and grow it by X% week over week. One of the big things (IMHO) that YC cracked was to find way to fund hard tech problems, using this very specific idea that worked very well in software. Break a big problem into small parts and show progress on it every week/month/quarter etc. It is a simple and elegant way to think (and work).

5. Advance something very important: This idea is dedicating your life to an important goal / problem. This idea stirred me the most (for personal reasons). This especially rings true for me, esp when I meet someon who found "overnight success" after toiling aways at something for 10-15 years. This idea requires a lot of reflection. Alan says: "Fix big human problems"

6. Argue for clarity, not to win: An amazingly simple yet powerful message. So much of our interactions would be better if we (if I) did more of this.

3 Sidenotes:

a) I wish he had answered the question about "What caused the regression?" that someone asks (I think Sam) after watching a demo of an early "iPad" from the 1960s. It is really important to understand this. Elon Musk often says that tech advancements don't just happen automatically, some group of smart people need to work together to make it happen. I think something happens that governments, VCs, technologists stop working on advancing tech in some areas. Some of it is explained by lack of a "great adversary" (WW II, Cold War etc), but still it would be great to understand this very deeply. Thiel's famous book also talks about regression in tech, without fully explaining it. It is an important observation, that merits a deep discussion. I would be curious to hear what Alan says. Maybe @Sama can fill in (?)]

b) Special mentions to two ideas, not because of the ideas, but because how he puts them. a) "Fund people not projects" (basically how early stage funding works) - but Alan says, these are "artists are people who do their art because they must". And b) While talking about "build your own tools if you have the chops" he says "...Otherwise you are working the past on some vendor's bad idea of what computing is about". I love how he puts these thoughts across.

c) I recommend the video @_pius links to in the comments: it is called "the power of simplicity". One of the great Alan Kay talks.

Thank you for the answers.
a_d··on Startup School 8: Jan Koum of WhatsApp
You mentioned in one of your talks about a small loophole in the early days of the App Store where apps were showcased under "new and noteworthy" if one made an update to the app - Q1: is this true?

And Q2: when you say "took off on its own" does it mean folks learned about WhatsApp only from word of mouth with no effort from the WhatsApp team?

Q3: what impact did charging for the app have on the company finances and growth rate?

a_d··on Startup School 8: Jan Koum of WhatsApp
What did you do in the very early days to promote the app (apart from Flyertalk)?
