Heh, it links to Inkstone talking about how LinkedIn has totally sucked up to China, but even Inkstone refers to the Tiananmen "crackdown", not the "massacre". So it's working, even in places it is supposed not to.

In the US, police have to murder black people in ones and twos, building up numbers slowly so as not to attract too much attention. In China they get to murder people wholesale. It makes them sloppy.

It seems strange how those who have chosen to participate in law enforcement are so resistant to the idea of not routinely murdering people. Not even just as a matter of, say, setting a good example.

The basic experiment can be varied to allow for that.

Specify a set of zones. Target different levels of advertising at these. Look at sales trends. Rinse, wash, repeat.

Note that major corporations often designate specific areas for product testing. The Chicago area, and Australia, see trial runs of McDonalds products and store concepts, as an example.

The fundamental concept of testing advertising effectiveness is not new. Here's an account from 1909 (from one of my faviourite sources on advertising and media, Hamilton Holt's Commercialism and Journalism):

That was when Steve and the CEO before Bob didn't get together... Steve did sell Pixar to Disney after all.

This really distills the message down to its essence. Though worth pointing out that this advertisement doesn't have to be seen as spam. Rather it can be just the right channel at the right moment for some people.

It could be. Imagine a world where movies don't cost millions of dollars to make.

> You need an experiment to prove that ad spending scales with ROI, as ad agencies claim

There is a limited audience that can be influenced. Just like house ads on a site (where you advertise to sell your own goods on your own site), there's only so much that is affected because you have finite traffic. There is a curve for every permutation of context (demographic, geographic, etc).
The interest is more on markets than individuals, in general, so what you're measuring is market response given advertising exposure, or more critically, ROI given spend.

The fact that Web and AdTech allow the appearance of individual-level targeting does not necessarily make that a Good Thing.
I guess I’m not sure how that is relative. Israel also spies on the US. My point is the asymmetry here in job opportunities between countries who are our, at least ostensible, geopolitical adversaries.
While lots of listings have minor discrepancies, I'm sure outright scams (like the ones described in the recent article) are pretty rare. I doubt doing random audits is going to have a significant enough success rate in finding them to make a difference.
There are a lot of people who are programmers but aren't "software developers", particularly not "full stack" buzzword enabled types. If you've been programming for a decade or two, and haven't had that title, you're likely not going to get that $70K that fresh grads will. Likely not even hired, for "cultural fit".

Hope you don't fall off the treadmill, because if you do, you'll find out there is no way back and no pity.

Income inequality is a sign that an economy is functioning properly. For people vary greatly in their talents, ambition, tolerance for risk, vision. Some can lead, delegate and inspire, while others cannot.

Some are great at collaboration, others love confronting difficult challenges. Some are great at squeezing suppliers and others good at pushing people to adopt the next wave of technology. Some know exactly what people want and others are incredibly creative. Some never stop learning.

Some do none of the above and only want everything defined for them with no risks or growth required.

How could anyone analyze all of this incredible variability and decide whether people get too much money for their contributions?

Income inequality rewards the development of all of those qualities.

Increasingly many do. Generally, the more anonymous the survey, the larger the proportion is. Apparently there is still official pressure there to pretend to recognize it as a legitimate government in exile.
I appreciate the sentiment and agree on an individual level but it’s not reproducible across the entire workforce. There is a certain degree of privilege required to even feel comfortable adopting this policy. As software engineers some of us have that privilege but few other workers do.

We arrived for a conference to an AirBnB and discovered when arriving at 10pm that it was likely illegal. ie got warnings about making noise and multiple people coming in simultaneously with suitcases, etc.

But your choices are either:

1 - pick a fight at 10pm, probably fuck around with AirBnB's shit customer support, maybe if lucky get to sleep at an alternate place by 1 or 2 am, then feel like utter garbage for the next 3 days;

2 - deal (with the implied: no more airbnb on business trips...)

This analogy does a surprisingly good job of highlighting what is wrong with robotics right now as well. Robots are hard to control at a low level, and typically you don’t want to. But sometimes you have to. We don’t have very good ways of specifying tasks or behaviors at different levels of granularity and having the robot figure out the right affordances to that tasking.

Huh. I may have just figured out my next research proposal.

Technically the fifth precept is about alcohol: Surāmerayamajjapamādaṭṭhānā veramaṇī sikkhāpadaṃ samādiyāmi -> I undertake the precept to refrain from fermented drink which lead to heedlessness. However, the hermeneutical understanding of that precept is it applies to any mind-altering substance. Why? Because losing control of yourself can trigger violating other precepts. For example intoxicants could lead to sexual misconduct which can lead to lying, and so on.

The GDP would be 10 times higher. It wouldn't be a lie. If the government wasn't completely blatant about it maybe store owners would only raise their prices by 9.95x and there might be a real GDP boost as well.

Is it stupid? Yes. Is it a straw man? Not so much compared to what is done in practice. When people seriously say that the policy is to "stimulate the economy" they mean incentivising people to consume rather than save. This has a positive effect on the economic figures but it is madness to believe it is setting up a better future; because setting up for a better future generally involves saving in the present.

> And since no one is suggesting that...

I haven't seen anyone propose a plan to tackle wealth inequality that doesn't involve confiscation and redistribution of some form or another. The argument is over whether that is appropriate or not.

As for GDP it is generally accepted that setting up a free market and leaving it alone maximises the GDP. There is lively debate about whether than is the best outcome. There is a serious argument that lower-than-maximum GDP with resource redistribution to the poor is better - which is what happens in practice.

> certainly not refuting, the elephant curve

There is nothing to refute. Inequality is not a problem - people can't even detect inequality! Nobody has a gut feel for it and the average level of mathematical intuition isn't high enough to understand the charts. Certainly people can't suffer because someone else has it really easy.

People suffer when their lifestyles deteriorate and we should be focused on preventing that. That is a completely different problem and one that actually deserves attention. The living standards of poor and middle class people is a real and ongoing issue that should be focused on. It does not matter if dealing with that makes the rich ricer. And in that context, the elephant curve can reasonably be interpreted as a massive success story that we can all be proud of as millions are lifted up to a better standard of living.
Why do they deserve permanently lower taxes?

That’s why I’d think of VR as a special case of AR. As you said, VR is in many ways is “easier”. So I’d think of VR as a special case of AR where the environment is also computer generated.

In other words, moving from VR to AR would require a ton of extra work to integrate the real world. But moving from AR to VR should be much more straightforward, albeit in many ways equally challenging because now you have to worry about two worlds - the normal overlay of AR and the environment from VR.

Now that I’ve said that, maybe I should think of them as more like related disciplines instead of special cases of each other...

Income inequality I'm totally in favor of as a reward for creating value. Outsized value, outsized reward. With that in mind, I have a few caveats. To function properly:

- Social mobility must exist: income inequality is available for everyone based on their merits, not coupled to things like circumstances at birth.

- Wealth inequality must only exist for the generation that earned it. Passing on your largesse to your children is just as bad as the plutocracies that the founding fathers tried to escape. They should be rewarded for the value they create, not the value I created.

- The bottom line is pulled up to the extent that you can live a comfortable life even if you fail.

Individually papers are generally not trusted which is why literature reviews are a thing. https://en.m.wikipedia.org/wiki/Literature_review

The issue is not on the science side, but how results are communicated to the general public. Administrators tend to add as much hype as possible, and reporters strip out all the important details.
Static is not a classification; in this case the classification was cycling between "unknown", "vehicle", and "bicycle", and each time the classification changed the history was reset. Then each detected object can be either static or be assigned a predicted path, but unknown objects without a history are always treated as static.

In any case, the history clearing seems to be a bug, they updated the software to keep the position history even when changing the classification.
My personal anecdotal belief is that it’s much, much harder for a robot to ride a bike than to drive a car. It requires human-level bodily/physical intuition that AI is nowhere near. We can barely program robots to walk normally, let alone ride a bike.
Very cool site, I have thought of making a CLI utility the same thing a few times but corporate computer limitations squashed that. I initially wanted to bring up bandwidth limitations but stopped myself as most people at work would not need to worry about that.
> Anyway, if the problem is relative deprivation we should focus on that, instead of focusing in inequality.

“Absolute deprivation” is having less access to material goods and services than some fixed standard.

“Relative deprivation” is having less access to material goods and services than others in one’s social milieu.

Relative deprivation is an inherent aspect of inequality; the two are inseparable.

> Is inequality the "cause" of relative deprivation?

No, it's not the cause in the same way that being a triangle isn't a cause of three-sidedness; it's more closely linked than causation.

> I believe there are more important causes, like corruption, for example.

Corruption can be a cause of (or mechanism of perpetuating) inequality, and thereby contribute to relative deprivation, but it's not a cause of relative deprivation independent of inequality.

Software engineers aren't special.

Please stop treating them as some enlightened class. They're not.

Software engineers face the same idiocy as everyone else. Every other industry has smart, creative, individuals willing to buck the system and try new things for an edge.

Horde is indeed a really interesting Elixir library. It's based on the CRDT library, DeltaCrdt [0], also by Derek Kraan. He discusses DeltaCrdt here [1] and Horde here [2].

BTW, Horde is a distributed supervisor, i.e. analogous to what regular Elixir OTP supervisors do, except that it can restart processes on different cluster nodes. It also provides a distributed process registry.

Daniel Azuma of Google gave a great 39 minute talk at ElixirConf 2018, "Docker and OTP: Friends or Foes?" [3], where he shows Horde (and DeltaCrdt) in action to keep a multi-player tank video game going while the Docker container it's running in gets killed and and the Elixir processes get respawned on another container. The state is persisted across Elixir nodes in other containers in an instance of DeltaCrdt.

(Again, the talk is really good -- if the above sounds interesting, you'll want to check it out [3]).

We'll have to develop AIs that are trained to detect if the essay was written by a human or by an AI.

I mean not a sad day for VR. Google is just being Google and thinking that XR is a tech problem. It’s not.

This aggravates me, because as a customer, I want the expert who charges the highest rate, but also does things really fast and correctly, because I know what a difference there is between competent and incompetent people. But other people don't think like that, and if I say I'm ok with a high hourly rate, they think I'm saying I want to be ripped off in terms of both rate and hours.
> The TAM wreck wouldn't have happened had the pilots flown the plane either.

Pilots were actively engaged, made a minor mistake by setting wrong thrust lever position on one engine, which caused the aircraft to disregard any other input and assume the aircraft to be airborne even when it was on the ground, spoilers and auto-braking armed, brakes manually slammed and one engine in reverse.

> That was quite a bit more than a bumpy landing.

I was referring to the 2018 incident. Pilots did everything by the book, yet lost elevator control.

> Don't forget that in some of these cases, the autopilot didn't disconnect because the autopilot couldn't determine that one of the RAs had failed.

Again, completely irrelevant as it did not prevent pilots from taking full control of the aircraft.

The rest of the examples you've thrown at me are also all malfunctions and have nothing to do with A320 incorrectly determining its state and overriding correct input from pilots.
> [...] because I know that bottled water is drawn from very different sources
