Ask HN: So what's going on with Drake content at Spotify?
Drake has dominated much of the algorithmically generated content on Spotify, to an extreme degree, leading to widespread complaints on social media.

I suspect this is a combination of:
1. Poor executions of algorithms, where the output is running unchecked
2. Legal and licensing agreements with the artist which prevent Spotify manually tipping the algorithms

Interesting implications:
- Spotify's stock price: it's these algorithms and content that purportedly make Spotify so good

- As someone working in the space of ML, I grudge this misuse of algos. There's a real chance an incident like this will precipitate another "AI winter"

Thoughts?
These are more interesting graphs.

Healthcare, education, and housing have all doubled since the turn of the century compared to median incomes. There are a few sectors of the economy that are absolutely crushing people who make a median wage.
> Even to just crack open that package we require massive machines like the LHC.

as a small correction, this is not true. what you probably really mean is massive amounts of energy, but large machines are not the requirement because RF-based acceleration is not the end solution. see laser-based plasma accelerators.

I haven't read the opinion of Alice directly, and it's been a long time since I read Bilski, but my recollection is that both of them turn on "it's long held that some things can't be patented as a matter of nature, and this patent is an example of something that falls into that category." There are things that Congress can't do, and given that SCOTUS is very likely to have an originalist rather than a legislative intent majority, the framework for analysis is very likely to be "what would an 18th century lawyer say about this?" rather than any amount of exhortation about how this is necessary to promote the progress of science and useful arts.

I'm not sure about the exact interplay of different kinds of law here, and I'm certainly not an expert in any variant of law. That's why I pointed out that the legislation might not have any actual effect as opposed to saying that the legislation will not have an effect.
If only that was all that stood in her way.

It's amazing how so many in our society wonder why kids naturally don't want to be forced to sit down, shut up, and passively consume arbitrary, impractical, and obsolete information. Our teaching and testing methods are stuck in the 19th century. Children who don't fit the mold of a cog in the industrial machine are drugged into submission.

>We must do away with the absolutely specious notion that everybody has to earn a living. It is a fact today that one in ten thousand of us can make a technological breakthrough capable of supporting all the rest. The youth of today are absolutely right in recognizing this nonsense of earning a living. We keep inventing jobs because of this false idea that everybody has to be employed at some kind of drudgery because, according to Malthusian-Darwinian theory, he must justify his right to exist. So we have inspectors of inspectors and people making instruments for inspectors to inspect inspectors. The true business of people should be to go back to school and think about whatever it was they were thinking about before somebody came along and told them they had to earn a living.

I read this blog post while simultaneously entering stories into our Pivotal Tracker (PT) sprint backlog.

There is certainly market demand for good, agile PM tools. Hope this Founder does a reboot after retrospective.
I think you could account for hold-out by having the resolve window be longer than the trade-insert window, at least to an extent.

The trade-insert window can't be too long, or it would leave lots of room for regret, like people who voted by mail for a candidate caught in a scandal two days before an election.
This is a cynical take, but, roughly speaking, in Europe, there are workers rights, and in the US, employment is at-will.

The US systems tilts the scales toward stronger employees. So, the more marketable your skills are, the more incentive you have to move to SV.

A slightly less offensive take on the situation is that, if you stay in Europe, you won’t be destitute, but you won’t get rich either.

However, note that there are many articles on HN that attempt to quantify this effect by looking at economic mobility. The consensus is that Europe is becoming more of a meritocracy and in the US, economic status is increasingly determined at birth.
Ask HN: Ethics of running a ML/AI product by hand
I have an idea for an ML/AI product. Though creating a model and building a prototype would be very expensive and time consuming. I am fine putting in the work to build it, though I would like to know that the idea has some sort of market appeal before starting. I can create a landing page and a (non user specific) demo of the product, though it would just have to be done by hand until I build the prototype. I have never done a startup/small business before so I am not sure if this is ethical/moral. Thanks.
I'd probably be willing to pay more than 41% (the 16%/year discount taken from your article, compounded for 6 years) but less than 100%, which implies that your conclusion overstates the value (to me in particular) of quality improvements during that time.

Of course, I don't actually have the option to get the same experience from an iPhone 5 today that I could have 6 years ago. As an alternative, consider a budget Android smartphone manufactured today. It's possible to spend significantly less than 41% of the price of an iPhone X (or an iPhone 8, for that matter) for a device whose quality is, I suspect, better in every way than an iPhone 5. If 16%/year is taken as the true rate of quality improvement, doesn't that imply that the fashion effect has an impact on consumers who continue to purchase iPhones?
I hope you get down voted not for taking a contrarian position but just because your comment does barely support the argument. Maybe anecdotes would help to illustrate your point?
This used to be true. Small HFT firms can find a niche thats profitable, but thats because there isnt enough money to be made by the big firms in those niches.

In the last few years there has been massive consolidation of the smaller HFT players, the space is commoditized and controlled by a few firms.
First step to creating conditions for 7 or 8 billion people to have good lives is to massively grow the economy.
Writing from Oakland, where I have a suspicion that many of the scooters taken off San Francisco streets for their permit monitoriom have ended up.

Point being that there’s a LOT of these scooters around. I think they’re great. I keep wondering where the people complaining about the carelessly left scooters are living, because the majority of the scooters in town are dropped off considerately, and don’t take up more space than bikes.

I think the backlash against the scooters is driven by people who don’t like tech, and by people who believe transit solutions should be driven (and owned) by the government. The scooters solve a problem, are dirt cheap to use, are available to anyone with a phone, and are environmentally friendly. The externalities are nonzero but not larger than bikes. There’s a lot to like.
That's impressive. I've read a great many analyses stating Musk'll never succeed in his model 3 ramp up. Let's hope he keeps this up in the coming months. It's a long way to 450.000 vehicles...

Nice to see a good reading of Nietzsche, which is super hard given his style and your own bias.

I agree with this, and it really puts the focus on why it is rewarding reading Nietzsche today.

The only thing I miss is the implicit and hidden Spinozism in Nietzsche.
Why it matters? - Spinoza can really help with the political aspect. Goal of true democracy and maximum freedom.

Such a reading will see The will to Power as the Spinozian conatus/desire. As for Power, not opressive power of rulers, but the power to live and act. The affirmation as Spinozian affirmation of joy (ie affirmate what makes you grow in such power)

If you make a strong enough mix, you'll just replicate the existing problems with OPC. But generally, you can DIY a cement with roughly 1/3 hydrated lime and the rest graded dust-3/4" pozzolonic stone. Let me know the impact of acquiring that if you aren't in Italy or, apparently, southern Idaho.

You can do it with non-pozzolonic stone but using ~2:1 lime:crushed terracotta, but it won't have the magic healing properties of the original.

(Note, going off memory on the ratios; they're probably somewhat off).
Yes, consolidation and layoffs. Go see how many KCG guys were kept by Virtu. If anything the industry has gotten smaller. People are just buying up flow now. There are no "big" HFT firms when compared to proper buy side.

> the space is commoditized and controlled by a few firms

Few firms != big firms
Of these 5 criticisms of contemporary theory, all of them except dark matter seem to stem from a suspicion about the eventual result through the lens of beauty, unification, etc.

I don't think it is really justified to label it this way. We know that quantum field theory is not the correct final theory because it breaks down at short lengths and high energies. It is in some sense most likely even the completely wrong way for looking at the problem. Quantum field theories are mathematical tools to deal with many particle systems and they have some nice properties like making locality manifest, they however also force things onto us that are non-physical or hard to work with, for example gauge symmetries and virtual particles. So even if there were no four different forces that could maybe be unified into one, there would still be a lot of issues with quantum field theory.

However, the dark matter problem stands out as one where measurements do not line up with theory, and seems more of a classic example of how we've typically "turned the crank" on making progress in the past.

It is of course true that dark matter is in a certain sense a more tangible problem, but on the other hand there is the problem that there are so many different suggested resolutions. Astronomical and cosmological observations may be the way to go for modified gravity or small black holes, particle detector experiments may be the way for weakly interacting massive particles, and each other resolution requires probably its own set of experiments. So that problem seems not so much that nobody is investing the effort but that we are not really sure where to look and for what. And in case of things like weakly interacting massive particles we somewhat come back to extending the standard model because such extensions may better inform us where to look.

Here's a spec from 2015:

https://github.com/ethereum/wiki/blob/c02254611f218f43cbb075...

From the block validation section: "Is block.timestamp <= now + 900 and is block.timestamp >= parent.timestamp?"

(In Solidity, block.timestamp is in seconds, and I think that's a direct translation from the underlying opcode, so I assume it's 900 seconds here.)
Yeah its funny, I still read outrage about those greedy "HFT players", as if HFT was still highly relevant. It was a blip in time of the financial markets when no one had high speed trading but a few. The alpha has been washed away.

>There are probably $100 million in profits in New York and San Francisco alone.

If we extend "San Francisco" to mean "Bay Area" and estimate that New York + Bay Area have a population of about 16M then if the company manages to get 5% of locals to become regular riders, $100M in annual profit is over $10 per regular rider per month. Assuming sufficient demand is there, consider the number of scooters that would need to be deployed and maintained to provided sufficient density to service this adoption level. Does that $100M in profit still seem probable in these two metros?
That's also what killed Rosendale cement. ~1 month cures as opposed to putting a structure on the slab as little as ~1 day after pour.
Yes, but "n homes for one month" is not home/month; it's home*month.
So it comes down to the choice of the kids. Apparently, making an origami jumping mouse is interesting for mayan kids, but not for american ones. The article doesn't even try to convince me that autonomy is the critical factor.

When a professor starts a sentence with "It may be the case that" it is clearly just personal opinion and not published scientific fact. The professor intentionally makes the disclaimer that she has no proof for the hypothesis.
I would second this. Enabling your child's interests takes observation and work.

One of the more surprising things I've discovered as a recent parent is how prominent tablets are as a distraction or learning tool.

I'm no exception. We bought our son a cheap, bulletproof Amazon Fire tablet, ratcheted the parental controls to the roof, and let him watch videos or play with it when he requests it (and use it as a helpful distraction when he gets bored in restaurants.)

I'm split on how to approach this. On one hand, I would have done anything to have this magical infinite learning device when I found myself bored as a child, but I also recognize that the content on it is more often than not designed for addiction. Our son is not yet old enough to understand even rough warnings of addictive behaviors, so we're kind of watch-and-waiting. We limit screen time per day, but as he gets older, and gets access to a web browser, I'm not sure how I feel about those limits in relation to traditional information sources.

The scrutiny is incredible. 'nuff said
Real compensation has become disconnected from wages mostly due to 2 factors [1]:

- Wage inequality (the average wage is growing faster than the median wage)

- Growth in benefits like pensions and health insurance which are not part of wages but are part of compensation

The inequality and benefits effects are about equally strong. Once you control for these 2 factors, compensation has risen at almost exactly the same rate as productivity growth, which is what you would expect of the economy in long run equilibrium.

Using a naturally hydraulic lime is important for creating weaker joints, but it doesn't save that much CO2. You only heat the limestone a few hundred degrees cooler (though for longer) and you don't pulverize it as much, but hydraulic lime is using the minerals mixed with it to harden just like OPC (which is why it can harden in such thick pieces like the base of the Pantheon), not pull CO2 from the atmosphere like a non-hydraulic lime.
Measurements aren't a concern, but what's "behind" them is unknown.
Submodular maximization is indeed NP-complete, but we can find approximate solutions in polynomial time. This paper speeds up the parallel running time of the approximation from O(n) to O(log n), meaning that they've found a way to make the algorithm more parallelizable, though you still have to do the same amount of work.
I’m from Levels.fyi and one thing we’ve found (seemingly obvious) is how specific skill sets can dramatically affect comp numbers. Ex. AI / ML is the hot stuff these days.

Finally got to drive Model 3 yesterday. A friend received his car a few days ago and let me try it on some suburban streets. Nothing fancy. But I did take it for a mini "drag race" against another buddy's Porsche 911. Again this was on a residential tree-lined street with kids playing outside. Not exactly fast and furious. But it definitely kept pace that first eighth of a mile ;)

In my humble opinion it outclasses all similar rides: Audi A4, Mercedes C Class, BMW 325, etc. And with charging stations popping up in every supermarket, office park, highway rest area, etc. It may rapidly become the brand of choice for young, urban commuting professionals.

From day one, HomeKit had hardware PKI (and strong crypto with a hardware security module on all their devices). All their authentication and messaging was fully end-to-end encrypted, but again, all _in hardware_. [1]

But the beauty of it was, you never felt that complexity in software as a customer. It's the proverbial Apple product. The tradeoff is, because you need this special hardware HomeKit chip, the ecosystem is pretty dull, or too expensive. And that's held back HomeKit adoption.

After playing chicken with the industry for years, Apple finally gave in and is allowing software HomeKit devices to get certified now. That actually does away with some of the security IMO. But that's ok, it bothers me slightly less to have HomeKit software based lights. Whereas, I wouldn't compromise on that when it comes to security (like locks on my doors, or the garage door).

Hope that helps.

While I've had aspirations to get more into home automation from the business side, most of my experience is as a consumer, so weigh my input that way. :-)

I have so many problems with these kind of articles / studies. For starters, does any of this matter? There seems to be a moral assumption that more motivated kids are somehow better.

I also dislike the ‘more autonomy’ argument - somewhere in the article it says something like ‘ we can’t give kids that much autonomy because it would be dangerous’. So it’s setting up a morally superior scenario and parenting approach and then discounting it as inapplicable in the modern context. What does that tell you about kids? Nothing. But it tells you a lot about society’s priorities.

I’ve got a counter conclusion; the American kids have seen the toys before and they’re just not that interesting. The Mayan kids have fewer toys so are interested in playing with them.

It's important to not confused the distribution of income between labour and capital with the rates of return on labour and capital.

Right now we have an unprecedented amount of capital sloshing around. When you increase the supply of capital, two things happen: The total income returned to capital goes up, and the rate of return goes down.

If you care about wage growth, look at wage growth. Looking at labour's share of GDP is going to give you a wildly misleading view in the context of large capital flows.
A company's value is still the present value of expected future cash flows to investors, right? For 2 billion and 15 yrs horizon, that's about 130 million in dividends a year. Profits still a bit higher to account for capital needs of the firm. That's quite the trajectory.

Another thought: are VCs and funds transparent about in what round they invest their own and the funds money? Can they sell their own series A investment in subsequent rounds with / without disclosure?
