A Big LITTLE Problem: A Tale of Big.LITTLE Gone Wrong
Ask HN: How much did your startup gross last year?
Seeing the interest generated from the salary progression thread, I was wondering if startup revenue would be an interesting topic to share.

I'm kind of thinking both the US and now China got there because of economics. At the end of WW2 US GDP was something like 50% of the entire world GDP. Most nations would be happy to do whatever they even thought the US wanted to have a good trade relationship and/or the aid that the US was passing around. And of course now China is the world's factory and more.

Personally, I think once the US is gone and whatever happens afterwards happens, if history somehow remains accurate, I think people will see the last 75 years as a world-wide Pax America with the most benevolent world leadership that has ever existed. I'm sure I'll get downvoted to oblivion for this statement, but, big picture, the US has done more to provide peace and prosperity (and even freedom and justice) for a greater percentage of humanity than any other nation ever.

If you look over human history, the natural human state is generally oppression, warfare, starvation, and disease. We just might be reverting back to the mean.
> If a given place has a higher level of homicide, doesn’t it logically follow that more people there resort to violence as a means to solve problems?

Correlation is not causation, and definitely not logic. A high homicide rate is not indicative of a trend in problem solving, it is indicative of a safety issue.

Specially, a high homicide rate is often the result of warfare. In the absence of conflict with a different nation, usually this means gang warfare. In that case, homicide is sometimes a business tactic, and sometimes tribal.

In some societies, human life isn't as valuable, or there is a precedent for settling disputes with violence, or insignificant problems are dealt with harshly, and so homicide sometimes is a problem solving tool. But it's also sometimes a cultural quirk.

My example is Baltimore, Maryland. Often the city with the highest murder rate, this is a result of gang disputes and the drug trade. The people are friendly and neighborly, and it's got a similar culture to a liberal Southern city.
Thank you for the feedback!

> First were the two images of a list of hyperlinks that look clickable. I tried clicking on the links to no avail thinking they were broken, only to realise I was clicking on an image. The two images in particular are the News Sections and Newsmakers images on the homepage.

We heard this privately from a couple of other people as well. We'll definitely look into making the Features section a lot less ambiguous.

> The second point was that I initially couldn't figure out how to access the service.

Yes, I agree that we haven't made it very prominent that the U.S. edition news is at https://www.newshound.co/editions/en-us/.

> I was trying to find the rest the news, not just the U.S. edition.

The U.S. edition actually has a World news section that has a comprehensive collection of global news stories. https://www.newshound.co/editions/en-us/#news-section-world

> I am not a U.S. citizen, so I might not be your current target audience right now.

We're looking for feedback from non-U.S. citizens on which other news editions they would like to see. For example, we've come up with Canada, UK, Europe, Africa, India and Japan as geographical areas that could have news editions but we'd rather work on what our readers want than what we think they want.

Uber still can’t get consumer Eats right. My last order roamed the city for 30 minutes before arriving cold. The order before that was stolen by the driver. They picked it up and left San Francisco.

Good luck getting an Uber driver to carry up 5 catering trays plus utensils and sides for your office. Maybe there’s a chance if Uber gives every driver a foldable cart that fits in the trunk without taking up luggage space for airport Uber rides.
Via open APIs? I like the idea. But then it puts the burden of development/cost on the bigger existing network. If you want to go this way then we should force APIs for all web services, not just social networks.
One of the most interesting part of the paper is how RL is used - especially here for Horizon where one of the goal seems to be problems where simulation isn't available. One such problem is push notifications:

Historically, we have used supervised learning models
for predicting click through rate (CTR) and likelihood
that the notification leads to meaningful interactions.

We introduced a new policy that uses Horizon to train a
Discrete-Action DQN model for sending push notifications
to address the problems above. The Markov Decision Process
(MDP) is based on a sequence of notification candidates
for a particular person. The actions here are sending and
dropping the notification, and the state describes a set of features about the person and the notification candidate. There
are rewards for interactions and activity on Facebook, with
a penalty for sending the notification to control the volume
of notifications sent. The policy optimizes for the long term
value and is able to capture incremental effects of sending
the notification by comparing the Q-values of the send and
don’t send action.
I don't disagree at all! I just understand why someone might be surprised at seeing the proper usage.
we're also hiring many other kinds of developers (from NOC to web to devops to Kotlin).
Yeah; low cost carriers are like IKEA or Walmart or (old) Amazon strategically, they deliver a known quantity at a competitive price and shave their margin out of the cost side rather than growing it on the revenue side. But they are also often low-cost for the customers, particularly the more notorious examples (e.g. Ryanair). Companies whose profitability comes from penny-pinching usually fit best with customers who are themselves penny-pinching.

(Oddly, it occurs to me that European companies do a really good job of settling in the niche of "penny-pinching to the point of being kind of terrible, but such an amazing bargain you can't complain"--IKEA, Ryanair, Aldi, Lidl. Walmart felt bad about being terrible and tried to get a little nicer to compete with Target; Amazon felt bad about being cheap and terrible and decided to chase a membership model and set up a cloud computing business on the side. Maybe it's because America has a deep inborn cultural fiction of not having social classes and companies feel embarrassed about obviously not catering to the quintessential middle class American family?)

This piece from 2012 (posted now why?) loses all credibility in the section called "2. Misleading results":

It is tempting to think that the 60% figure that’s being thrown around in media reports is just too large a percentage to ignore–even if the studies had some flaws. But do you know what the “60%” statistic is actually referring to? Boyle and Hill explain: What does the frequently cited “60% relative reduction” in HIV infections actually mean? Across all three female-to-male trials, of the 5,411 men subjected to male circumcision, 64 (1.18%) became HIV-positive. Among the 5,497 controls, 137 (2.49%) became HIV-positive, so the absolute decrease in HIV infection was only 1.31%.

That’s right: 60% is the relative reduction in infection rates, comparing two very small percentages

I don't even know where to begin. What does he think people will interpret it to mean? His entire point here is made in bad faith. What he's saying basically comes down to "the infection rate in this trial was low to begin with, therefore there's no point trying to make it lower," which is preposterous. The authors claim a reduction, which any speaker of the English language should know how to interpret.

I think it's entirely valid to argue the validity of the study and the blowback issue, but his sloppy argumentation throughout the article is underscored here.

No, just some things that you want to think about before you drive on the Trans-Canada in the middle of January.

I mean, you don't need to think about them for very long, but you do want to have a plan for being stuck for hours, or having to turn around in the middle of Nowhere, BC.
And your comment brought back memories for me, too. For various reasons when I was young I had to fly internationally a lot, and I have memories of endless hours sitting in dark cabins listening to the CDs I'd bought in the previous country, checking my precious supply of AAs and drinking every coke in the plane. Or the hours spent waiting for connecting flights in dim airports, again with nothing but my trusty discman for company. Damn I loved that discman!

I think it was the nostalgia for endless travel that led me to book a 7-day rail pass in Japan a few years ago, and spend the entire week just catching trains to nowhere, staying a few hours, and catching them back - spending the entire trip just staring out the window as the countryside flew past at 300kph. In many ways I can't remember ever feeling more relaxed.
This stuff is still so expensive that it mostly only happens for Presidential campaigns, but this was a huge part of Obama's campaigns and I think all four of the last general election campaigns used those techniques. (Obviously these techniques weren't perfect, given that both 2016 campaigns were very surprised at the result.)
I find vegetation massively helpful, because I have a pretty good idea of the shape of the forest areas around my city (both from driving around and also from looking at satellite/aerial photos). I can actually find a lot of places faster looking at the shape of the forest, parks, etc. than by either looking at the streets or even searching!

It's just making the map data match the real world better, and making it useful for more than just driving.

I wouldn't mind having things be created through autowiring and the like, if it didn't make it harder to make the things explicitly, without autowiring.

Ideally, making something automated should not make it harder to do the same thing manually.

“Make your boss a hero” is one of the most deranged things I hear managers say. At my first job out of university, my manager told me my job was to make him look good. I instantly wrote him off as a moron. We worked for a publicly traded company. Nobody cares about how you look or your little empire. This isn’t your money. You are hired to manage it for the shareholders, not to look cool or be a little rentseeker
Wayland future and legacy
In my opinion, the little nugget of truth here is that the focus of the Chinese government has almost always been inward, and not outward, and definitely has been for the last several generations. Their greatest threat is not the US or anyone else, it is and always has been (and will be) their own people.

If you think about it like this it explains everything that the government has been doing for decades. They limit the population growth so that they can feed everyone and keep discontent down. They focus on the economy to keep discontent down. They build regional and world status to create pride in a greater, unified China. Even their tv shows and movies glorify themes which show a united China as one, and always the government are the good, humble servants. Military power, technological independence, even hostility towards other countries is mostly to build patriotism and unity among their own people.

And of course they restrict the internet, control the media, and limit what people can see and say.

Even when China was being successfully invaded by the Japanese, the existing government was more concerned with the Communist revolution. When they finally got desperate and banded together with the Communists to fight the Japanese, they lost ... to the Chinese Communists who took the opportunity to overthrow them.

So in that sense, it is helpful to understand the Chinese government and the things they are likely to do, and how to interpret them.
> if it's not convincing to another, this other person must not understand it properly and must just need to be educated on the subject. Or, more cynically, they aren't paying attention because they don't understand the importance of the work.

Here's a thumb rule I try to follow: Before having a strong opinion towards one side, one must be able to be articulate both (opposing) points of view. So, my goal in any discussion is to reach that stage -- mutually, if possible. After that point, I'm willing to trust reasonable people to exercise independent judgement. At least we can get a shared understanding of which differing assumptions lead us to different conclusions, and see whether there are any tests which will help us validate those assumptions.

> Almost everyone has some ego at stake.

Aye, we're all humans! All we can do is strive to be a little better each day :-)
The same with regards to listening to someone -- I try to listen carefully and respond sincerely with what puzzles me. It's up to them what they wish to do with that.

> It can be incredibly labor-intensive to delve deeply into a paper and determine how right or wrong it is. If it's wrong, it's even more work to understand precisely where and how it is wrong, and then give the kind of feedback a hypothetical egoless author genuinely interested solely in ideas would like. This can be a great deal to ask, unpaid, of people who have other things they would like to be doing.

Absolutely! I don't mean to imply that one should take every crackpot paper seriously. I guess each researcher has a circle of respected colleagues whom one can trust for a little bit of indulgence. Also, this is partly what professors are paid for -- so I would hope they're willing to spend some time with their maturing students, and their colleagues, who have proven track records as researchers.

An interesting related tidbit: Some of my physics professors were very sincere in asking eager grad students to have some humility and avoid spending much time on the murky swamp of quantum foundations (which has claimed many decades of smart researchers' lives)--and definitely not by ourselves, at least till we had a few manifestly productive years working on other things, and developed enough of a research sense to understand when to back away from unproductive lines of inquiry.
That description seems exaggerated. It implies they've got your full browsing and search history, which is a bit unlikely.

Honestly, if you're calling some support number they usually already have your name, home address, and so forth. There's plenty of information you can link to that.
> Sexual reproduction forms trees.

No it doesn't; it forms directed acyclic graphs. (Consider the fact that all humans share a common ancestor). There are probably parts of biology where reproduction does form a tree, but given the existence of horizontal gene transfer, I am not confident in speculating what they are.
What part of San Francisco with 1 story houses are you talking about? I lived there for 5 years and the only ones I remember were in the parks. Even the low density is almost all 2 story just to have a parking space.

No, I'm talking about the burbs where they've decided to put 5 story commercial next to city blocks of single family homes on quarter acre lots. 2 stories would be fine... 25% of the houses are anyway.

There's always going to be an edge to zoning, but going from 1 story to 5 is stupid. There's no parking, no transit, no shopping, just offices and houses. The commercial was single story and fit into the neighborhood, but now going 5 it's just going to cause problems.
I'd be really interested to know how you got to "$12/person/year".

I would be interested in the values for other platforms. I think it builds a more tangible argument when explaining the hidden costs of using various "free" products.
That’s quiet an escalation in both of mental ability to take a life and crime level. Armed robbery is lower than murder one. It’s also a jump to think that you’d go from relative coward to iron man murderer.

Uber betting on the notch removal next year I see.
My 9 year old car has this capability built in to the on-board nav system. It includes gas stations, restaurants, rest stops, etc. It also always shows cross and current street names and can seamlessly zoom out to the current continent and has a 3D terrain elevation mode. It was designed over a decade ago.

The difference is that it was designed as a premium option to solve a problem for a user. Modern smartphone apps appear to be more about gathering data and steering users to the platform owner's desired destinations.

In my opinion, yes. I chose the "distractions" with the thinking: "if I spent time on this for a year and looked back, would it have progressed me in any way?".
