You might get a lot out of Nir Eyal's book, Hooked: How to build habit forming products[1]. It would be interesting to see how the lessons there apply to physical products like yours.

>The Chinese value the appearance of working hard, not actual hard work.

It's very interesting how deep this type of behavior is ingrained in their culture.

For example, western cultures have Aesop fables (e.g. Tortoise and the Hare) which tend to celebrate hard work and punish laziness. Eastern cultures have fables that tend to celebrate being clever or manipulative (e.g. The lion and The Rabbit).

It's also interesting to see how this plays out today. The Chinese Happy Farm (original Farmville) was a huge success in part because it allowed users to steal crops from their neighbors. This type of behavior is considered okay as long as you are clever enough not to be caught.
Looks like someone things "dangerous" and "useful" are mutually exclusive. See also electricity, automobiles, consuming food, etc. No one is saying "don't use abstraction ever."

Maybe this metaphor will help:

"Using other people’s code is like surfing. You control and surrender. You’ve got to trust the wave to carry you, but stop paying attention, and the first abstraction leak will throw you under the water."

https://medium.com/@dan_abramov/youre-missing-the-point-of-r...

Sure, you could say "bad abstractions are bad." And it's true there's a spectrum. Some are much less leaky than others, of course, some have the boundaries of what they do and their interface outside more elegantly shaped than others. But saying "well, we just don't want bad abstractions" doesn't capture well the fact that all abstractions either leak to some degree or are awkward coverings for some problem domains.

Nor does it really get us where we want to go in terms of "exactly what abstractions we want." We want useful ones. We want minimally dangerous ones. And the way you get the latter is to understand how abstractions are dangerous.
It is certainly interesting that the "National Assessment of Adult Literacy" report indicates that only 13% of adults can perform that sample task of "computing and comparing the cost per ounce of food items".
> And even the dictator himself didn't help matters

An even better example would be the ongoing investment in prestige battleships when it was the U-boat fleet that brought Britain to within a fortnight of surrender.
> There's elegance and quite likely reduced computational load in a functional approach that can give the wave height value with only the inputs of the coordinates and time.

Sure, except there isn't any known closed-form expression that can model water waves in cases like the author is aiming for. (In the steady state water waves are roughly trochoidal, not sinusoidal, if you're interested.)

What happened in this article was that the author started with a mental image of what a water drop looks like, then hammered on a sin function until there was a resemblance. That's fine in and of itself, but he might as well have drawn a picture! Whatever resemblance he did or didn't achieve to actual water was a function of how good his mental image was and how long he spent working on the similarity, not a byproduct of the math involved.

What's nice about my awful stateful approach is that the physicality arises unbidden. If you code it up it will behave like water all on its own - you won't have to randomly fiddle with it like the article's author.

Also, with my version you don't have to start out knowing what water waves look like. It will show you. ;)
I know the Tuskegee Institute (as well as the NAACP) classified Till's murder as a lynching, but the Equal Justice Initiative's methodology required that three or more people participate in the lynching, which would disqualify Till from being counted in their report.
Hey Dan, thanks for responding.

I can't address your first point because I agree with it - part of the reason I'm pessimistic is because there isn't a strong business model.

However, I think that it's hard to know who to partner with. For all the organizations that you can partner with to produce fruitful research, you have many who are trying to make a quick buck on the trendiness of security. We don't have a lot of Mayhems. We have a lot of Acunetixes.

I agree that the methodologies and tools required to write secure code already exist. However, I don't think it's fair to place all the onus on software developers. Even if they avoid C/C++, they still have modern pitfalls in just about any language.

I think more research should be done on security software of course, which is why I wrote this blog post. What my post doesn't address however is that I also believe more research should be done in educating developers. It doesn't matter if all the tools to help them exist if few of them bother to look for them. Research could help in this regard - education.

Finally, I think you're much more familiar with Mayhem than I am, but I call into question the bugs Mayhem found. How many were high severity and/or actually exploitable? (I'm actually asking because I've seen conflicting reports from both Mayhem and Michal Zalewski on the matter).

When I say being used in the open, I mean in a similar way to Project Zero's activities. Mayhem was used once on Debian as far as I'm aware, and to my mind it looks more like publicity than an ongoing effort to find bugs.
I'm not sure why that article exists given it's content can fit in a single tweet. It's 90% finger wagging "you don't know what I know" and 1 sentence of the point.

Anyways, this sentiment has become popular recently for some bizarre reason. All of the things that are the "real strengths" are in fact only possible because of virtual dom. So in my eyes the virtual dom is the important part, as the enabler.
I don't understand the reasoning here; how could launching today with a guaranteed failure to recover possibly be more valuable than delaying another day or two with a shot at recovery? The only way it makes sense to me is if sea heights are predicted to remain unmanageably high for unacceptably long, or the chance of recovery was very low to begin with.
Never replace Helvetica with Arial: http://hipsterhitler.com/typewriter
Not only that, but in fact the kinds of things that are meaningful and valuable to people are often shared with other people, which then provides us with the additional meaning kick of sharing, which, I am told, is caring.
Numbering is the biggest problem with legal documents -- cross-referencing "section 1, paragraph 3" type stuff.

Also see my comment below.
Or, female CEO's are a more risky prospect than male CEO's and companies have different risk/reward motivations based on their situations. If a company's facing a tough grind for a few years they may be risk averse and stick with "safe bets" wherever they can.

Or, years of fighting "the patriarchy" has left females uniquely qualified to lead companies in the fight against changing market conditions.

Or, prospective female executives are probably very aware of the social and political climate we live in and that may make them more risk averse in regards to accepting positions, they may place a higher value on taking positions at companies on the upswing.

We can do this all day but I doubt the data's going to give a clear answer, we'll all see what we want to.

You're probably already aware of it, but Martin Thompson of LMAX has done a lot of great work on HFT systems and his blog "Mechanical Sympathy" is excellent:

Although a lot of people think HFT is just a race to the bottom (and they are probably right) it's still great fun to try and wring every last nanosecond of performance out of your code.

China's economy crashed big time in fact. They took on upwards of $30+ trillion in new debt in just six or seven years to continue faking the old levels of growth, trying to buy time. They pulled a Japan, at warp speed.

In other words, China took on nearly twice as much debt as they gained in GDP expansion over that time. Since the later part of the previous decade China has seen a plunge in the return on invested capital when it comes to GDP growth - the situation is so dire now, they have to add over $1 of new debt per $1 of new GDP they get out of it. The party is over. China is already the most indebted country on earth (while half a billion of their people live on $2 per day), and their pace of debt accumulation isn't slowing down. The outcome of that financially toxic situation is obvious.

To keep faking 7% growth, China has to take on $20 to $30 trillion in new debt in just the next five or six years. It's a scale of debt the world simply has never seen before.
You tend to get legal "assistants" that end up taking multiple documents from different people and manually consolidating changes.

Terrible state of affairs!
Togetherness: Building community and beating loneliness in a digital world
That'd also be an interesting thought experiment. The modern nation-state as a concept is barely a century old; before WW1, a number of prominent countries (Russia, China, Austria-Hungary, much of Africa) thought of themselves as empires or kingdoms, and people's daily allegiance was more toward local municipalities and neighborhoods than the abstract concept of a nation.

I wonder if at some point in the future we'll see pseudo-corporatism as a social organizing principle, much like in Neal Stephenson's books.

The shuttle is a great example of that relative trend. 2 accidents over 537,114,016 miles vs 2 accidents per 134 flights. Though commercial airplanes are fairly safe private planes are little better than cars.

The customer comes first.
We didn't end up with what "we" want, we ended up with what Moloch[0] wants. Its an important distinction. Market economy and other feedback loops we run on produces results that are only partially aligned with human needs. There can be literally solutions that no one on Earth wants or needs, and yet they get created because they're local optimas. People have every right to reject and fight results they didn't want. It's how we keep the system aligned with human goals.

That gets into the societal aspects - after working for their basic subsistence, how much time in the day is left for working on other things that they could sell. In the US, the creation of industrial-scale farming meant that food became plentiful and cheap enough so that there was capacity & time left over for work that could then be used to create a profit.

There are other factors at play of course. India has an enormous bureaucracy that soaks up much of their excess capacity and stifles innovation. The remains of the caste system also means that some of their most productive people aren't working effectively. Nigeria is doing much better these days, but still suffers with a large amount of corruption. Pakistan & Brazil - I don't know enough to comment - perhaps you can fill in why they aren't growing as fast as they might.
That's why I am so interested. I could see how getting blind drunk once a week might actually reduce total mortality. Perhaps those who get blind drunk only occasionally under planned conditions have fewer accidents than those who drink regularly and therefore spend more time under the influence.

I agree that a measurement protocol would be difficult. But the OP was based on self-reporting. They could ask "Have you, in the last week, ever been above the legal driving limit?" or "What is the most you consumed in a single sitting this week?"
You could try, and Engadget would probably not, if they hire a good law firm, use copyright to try to stop you. They could however potentially use other parts of the law including, depending on the jurisdiction, rules on unfair competition, passing off etc.
Big Bang may have never happened

Reading the BBC article reminded me of all the fines also. People are paying extra because drug companies push off-label uses on consumers and then get fined for it. It's not like the company really pays, they just up their prices a bit and push it onto the consumer. That sort of off-label usage doesn't happen in the UK so much, because doctors don't have any incentive to prescribe anything other than the NHS approved drug for a condition.
Hm, use Tumblr with a domain name and you're all set.
I think you're conflating people, if that was in reply to my immediately previous post.
Why would a company make them launch without recovery? SpaceX has always focused on the paid mission first and runs tests as a secondary task if there is sufficient resources available after successful payload delivery. Also, the cost is expected to drop by a factor of 10. Launches are ~60mil USD (can fluctuate based on specs). Even conservatively, the company would likely pay a 40 million dollar penalty if the whole rocket had to be jettisoned. Some missions with higher payloads will ideally be serviced when the Falcon Heavy comes on line.

In terms of weather, I reckon they could have a secondary site to land if weather prevented it in the primary zone. If you mean in the interim before approval of domestic landings on or near launch sites, spaceX probably has pre-existing contracts to do launches. Maybe they would discount them a bit for a better window, prior to Air Force/Regulatory approval.
This feels pretty high level. Knowing that we want to build the most profound feature for the most number of users is not very controversial. But there are many ambiguities about how you measure profoundness. There are many things that I could fill up my time working on each day all in the name of building profound things - e.g. do I build this feature, do I refactor, do I do customer interviews etc.

In my experience, teams always struggle with that level of decision making, and the problems stem from optimizing for the wrong tasks, even if someone is overall agreed on what the "most important" metric is.
Wow, this is fantastic. Thanks for the link. I'll be reading up on this now.

How to become a rock star with $290 and an iPhone
The work going into whitebox switching and routing is super exciting. I really dig this stuff.
> No, as I said, I met an overweight person who consistently ate well and exercised (a college roommate). I have no idea how many calories they burned.
By comparison, I ate much more and exercised much less and had very low body fat. Again, I have no idea how many calories I burned.

Typically when I'm told this either by people wanting to lose or people wanting to gain I just ask them to write down everything they eat for week. Guess what we learn at the end of the week? They really had no clue what they were eating. The skinny people were barely crossing 1500 cals and the overweight people were 2500-3000 and had zero idea. The other fun fact here is that food wise both of those are not very far away. A couple sweets or sugary sodas each day and you can easily cross over.

While there are likely exceptions and extremes (thyroid issues), the vast majority have zero clue about how much they really eat. This is why things like Weight Watchers work so well for many people. You get X points/day. Foods are worth differing amounts of points and when you hit zero stop. People quickly learn what foods are 'free' (veggies, most fruit) and load up on those and then plan the non-free foods to maximize taste/fullness/whatever.
Also Open Sourcing something without a license is very pragmatic too :). When did "open source" became a term for "we're nice giving you stuff for free".

I think the word you're looking for is "convenient" it's easier to just upload the .doc they're using and write a blog post than create a Github repository with a readme, and review pull requests of people correcting spelling / grammar mistakes and such and such.

Props to YC to give this away for free, I read it, looks good, but don't try to excuse them for their laziness by calling it "pragmatism" just because it's YC and we're writing on their forums, great content but they shoulda been more professional before using the words "open source".

This is a LEGAL agreement, that says in the announcement is OPEN SOURCE and doesn't have a license attached to it... Think about it.
great blog post!
DARPA: No One's Safe on the Internet
I concur. In private practice I have negotiated, drafted, and revised hundreds of industry agreements and a redllined MSWord .doc is what I create and expect from other attorneys. There is still a percentage (I personally find as much as 20%) of more seasoned attorneys that use WordPerfect. I can only describe their unreasonableness about it as being brainwashed to believe using anything but WordPerfect would somehow be a negative reflection on the firm/lawyer and that Perfect has some functions Word does not that are specific to the legal field and yet can never actually be named. Long story short, the formatting between the two programs is the worst.

Isn't this more like "Lego" for hardware?

In MacPaint I can paint anything. In your toolbox I can only assemble something with the parts that you give me.

The MacPaint analogy would hold water if you'd let me draw any shape that I want (to be 3d printed), and merely assist by enforcing the basic constraints required for my device to be manufactured and functional (e.g. enough space to put the electronics in, etc.).
I partly agree with this. Although I'm convinced there are actually people who CAN do a lot of "this stuff" quite good; I'm convinced that most of us mere mortals would be moderate in some of these at best while struggling with the rest.
A Robot Friend to Assist the Elderly
So why is node, with it's callback hell and single thread, worse? Is it syntax? That single thread assumption can free you from some significant problems, you know. golang's own http lib is event driven and uses callbacks, but perhaps less hellishly. I agree it is hard to push go if you don't properly understand it.
Why is something overly broad stereotyping?

People don't treat populations and individuals as the same thing; the population is its own entity with its unique properties, and, obviously differences. The question is whether those differences are sufficiently exploitable. This is how policy works. If you are saying that you can't generalize over a population, you're saying that there are roughly zero between-population differences that are exploitable for strategic policy. Random things are unstrategizable.

I think that the Chinese and Japanese value hard work more than Americans and Canadians, and I think so because Americans and Canadians have an unfortunately true belief that intelligence is highly predictive of performance, and also that intelligence is not meaningfully improvable. On the other hand, I think that Chinese and Japanese people have the belief that effort is a far better explanation to performance.

The problem is that performance must surely be at least a combination of effort and ability; a depressed person may have the bodily ability to pick up the phone for their friends, but they might not care anymore.

I thus say this: if you go looking for studies on cross-cultural pedagogy, I claim that you're going to find that American and Canadian students are significantly more likely than Chinese and Japanese students to avoid harder challenges, to pursue easier challenges, to practice mastered over unmastered material, and to avoid a problem after poor marks. Does this speak to all work? Of course not. But it's a window into culture, rather than just comparing mean hours studied or worked between populations.
