Ask HN: (yet again): What is the best affordable programmable drone?
As the field seems to move quick, let's ask this again.

Previous threads:

- 2015: https://news.ycombinator.com/item?id=8989411

- 2016: https://news.ycombinator.com/item?id=10872233

- 2017: https://news.ycombinator.com/item?id=14201207

I wouldn't focus solely on the lowest cost range, as the other threads did. What are the best programmable drones, let's say, <$250, <$500 or <$1000?
This line would make a great square for "Hacker News bingo."

One big one is air pollution. It is huge in terms of health affects on the population but we ignore it because of the feeling that it cannot be helped. When we finally clean our air it is going to seem ridiculous that we accepted our faith to live our whole lives in toxic fumes for two whole centuries.

Ask HN: Can AGI Be Achieved Through Modular Neural Networks?
Neural architecture is largely modular in many higher order organisms, like most mammals. I think Modular Neural nets, https://en.wikipedia.org/wiki/Modular_neural_network, with some sort of dynamic topological intermediary will probably be a better approach to more complex, hierarchical problems, and might be a decent shot at AGI, what do you think? Does anyone have further reading about this? I also read Professor Hinton's work about Capsnets and neural module nets, which are somewhat related.

I'm working on using them for disease outbreak forecasting.
If you do it knowingly yes...you have the ability to say no. Do you think you are not a victim, or are you just complacent enough that as long as you have X you are fine and I can going knowing I was a good person. You dont have to create victims you do have an obligation to prevent them.
The praries are cold, flat, and devoid of any cities of interest (in the sense that people visit to see the cities).

People do live in cities in alberta, but the cities are mostly car oriented. If you want to live in a walkable area you're mostly out of luck in the part of Canada between Toronto and Vancouver.

There are reasons people really enjoy being in the praries of course, but it really is a serious lifestyle choice you have to make.
Thankyou! Gave you an entry here https://www.kickscondor.com/hrefhunt/
The idea at work here is Alan Kay's, to bring the spec into the language as code somehow. Prolog is better suited to this than many other languages, simply because it is so easy to reuse existing operators and structures but overlay them with new semantics, as well as adding your own operators. But I think you can do that same fundamental idea in any language. The ROI will often be lower though, if you tried to do what I did in Java, for instance. In this case the core is very procedural. That was kind of fun to do, just as a reminder that Prolog can do that without it being onerous. But the ROI would have been even higher if the core problem involved nondeterminism, constraints or deduction in some unavoidable way.

A lot of the code I write in Prolog is written to demonstrate you can do practical things in Prolog without it turning into C or Pascal. I feel that Lisp managed to shed the "this is only for AI" stigma, thanks to books like Practical Common Lisp and partly thanks to Emacs itself. But Prolog is still sort of thought of as this freak language only really useful for solving Einstein puzzles and sudoku.

Prolog is not my strongest language, and I am far from an expert in it. But, I don't think you have to be an expert in it to use it productively and enjoy it. If I had tried to do this problem in Haskell or Python or Java, I would probably have solved it in a completely different way.

I don't know if this addresses your questions or not, but I'm glad to talk more.
From one friend which is working in agriculture, glyphosate was used before planting the crops, to remove invasive species. But it does not change the fact that it's toxic to humans.

VLA Detects Possible Extrasolar Planetary-Mass Magnetic Powerhouse
I was making a slightly different distinction; between taking a copy of something which is available to buy/rent publicly, and taking a copy of something which is a “trade secret” as in the secret sauce or secret recipe which makes your product special.

Taking a copy of something which is available to buy without paying is perhaps depriving the company of one sale, or not if you weren’t going to buy it but would happen to look at it for free. In some cases this free copy can even have positive net expected value, e.g. in the case where you read a book or watch a movie without paying for it and then tell people how great it is.

However in the case of stealing trade secrets it directly undercuts the entire value proposotion of the company, particularly since trade secrets are not patented so anyone is free to replicate the result and sell it in the marketplace, presuming that they independently invented the same process.

So taking a copy of a trade secret is considered espionage or corporate warfare and is a direct attack on a company in a way that personally ripping a copy of DVD doesn’t come close.
It's also more complex than simply measuring how much of the securities lending revenue ends up back in the fund.

Most of that 60% for Fidelity's funds don't end up back in Fidelity's pockets either, but instead in the pockets of the people who borrowed stock from Fidelity investors in the form of rebates. You can understand this like: the borrower puts up 100-105% of the collateral and so should get some portion of the short-term rate on that cash. It's not clear why the disparity exists between Vanguard and Fidelity though.

iShares is truly different where they actually take 15-30% of profits for themselves.
A point that I've read in N.N. Taleb's incerto series is that it is a matter of scale. A small artisan who puts their name on their product is less likely to poison you and fuck your life up. Megacorps though operate with a very different risk profile and can take pretty antisocial decisions.

Regulation must keep a watchful eye on the megacorp - a small fishing operation is a net positive for society but a fisheries giant can drive entire species to extinction and threaten food supplies.

How many people know that a third party can for instance give Facebook a list of emails then FB matches that list up to thier subscribers for ads? How many people know that Google records every time you open any app on Android and logs the activity? I found out when I logged into my dad’s account.

How many people knew that third parties can get information about you if your friends sign up to something?

>the worst clients get the best pricing

That's how it always is, in every market. Fact of business. Your worst customers are the most price-sensitive and the least loyal - but you can't turn them into better customers by making them pay more in a tiered loyalty structure, that's not how it works. They'll go to a competitor.

Your best (meaning worth investing in) customers on the other hand, WILL pay more. That's not a bad thing. They're happy to do so.
Um... That's not true.

My spouse and I could spend whatever we wanted (your 20k or whatever) on flights to Europe from the US in business class; we could pay in cash tomorrow and not really have to worry. But we don't, because that would be stupid.

Flying business class to Europe for 10k each is not something we value.

Similarly, we don't buy steak when we go out to eat. My spouse can cook a steak from our local farmer better than any steak I've paid $45+ for. We don't feel restaurant steak is a good value. Seafood? Yeah, we'll pay for that -- don't know how to cook it well, so it's a good value for us.

There is a significant difference between price and value. Coach is a fine value for me. I'm short, and I want to give my money to restaurateurs in Portugal, not American Airlines. The pleasure per dollar is a much better ratio. (BTW, Portugal is a great value :) )
There are people doing vegan keto. It is theoretically possible.

I imagine it is the most boring diet in the world though. :)

From what I've heard vegetarian Keto isn't too bad.

I'd worry about getting healthy oils on a vegan keto diet, healthy vegetable oils get expensive very fast. Most keto diets don't pay much attention to fat sources, but while lots of canola oil technically meets the macros, it'd not be healthy at all...
How much power have companies like vanguard exercised in this situation? I thought the problem with vanguard was that they didn't care about the outcome of individual companies and so would vote for maintaining the status quo.

> Megacompany sounds intimidating, but I perceive Apple to be quite tame. They mostly just make hardware.

They cause enough damage to the industry by being crazy bent on lock-in. They are even worse than MS in this. And with more money, that damage will be only worse.
Apple Maps used to do this too. They took it away a few versions ago for reasons I don’t quite understand. I really liked the “Pale Blue Dot”-like overview of the Earth when zoomed out all the way.
Now you're conflating two different notions. You're (and your quotes) are talking about the first bullet point from the article. In turn, when taking about the last one, the one chosen by article author, from my experience, I'd say that it's beneficial not to even consider it in time, i.e. don't think about it as process, don't think of it as something completed. There's no completion, since there was no process to begin with. The object just is, and we can manipulate it according to the rules.
There are many grey areas when not using a 'formal' rating system (eg: college degree). But the formal system is rigged in that it isn't available to everyone - and is heavily biased towards those with the right pedigree or luck. Not to say nobody gets into college through hard work, just that it's skewed.

I feel most people are able to identify a good guitarist whether or not they like the music the guitarist plays. Even when the guitarist only plays with 1 string [0].

>For the first day of class, I sent around a questionnaire, asking students to rate themselves as beginning, intermediate, or advanced.

I blame your questionnaire for not defining the levels of play or being granular enough (1-10 scale). With those options I would assume "beginner" means "doesn't know how a knight can move across the board or the difference between a rook and a bishop", a 1 on a 10 scale. For example, I'm a "novice" chess player for sure - but not a "beginner" (some people may use these terms interchangeably), a 2 or 3 on a 10 scale. Assuming the students in the club knew the rules of Chess - it's not a surprise nobody answered "beginner"!

Assuming the system is put together correctly, all inputs certainly ought to be correct, because whatever component is producing the corresponding output simply wouldn't have compiled if they weren't...

Interesting point re: Einstein. However, I think what he did was literally to ensure that the US won the war, not disclose a societal consequence. Since that was an existential threat, it falls under different rules. Object detection is not an immediatel existential threat.

Also, I kind think the secrecy of the manhattan project was essential, and after carefully reading multiple histories, I am convinced that Leslie Groves was a genius who did more than a good job managing the project. If you look at how he declassified the project, they did everything right. THey had a historian with access to all the data. And scientists who understood the context. And they worked together to release as much information as they possibly could, and even helped make the case for transitioning control of weapons to civilians.
> They will maintain their poison-happy monopolies.

They will because people will still buy their crap. There are plenty of lazy, misinformed, ignorant people who would do anything to keep happy-poisoning themselves, including fighting legislation meant to protect them.
More downvotes. /shrug so much for discussing dissenting opinions.

My point is that it is unfair to the productive to take by force the product of their labor and give it to those who are unproductive.

If you doubt this and you have children, try an experiment. Children have a good sense of fairness (it's inborn). Take (without their consent) something they earned (and value) and donate it to Goodwill. Afterwards, when you tell them what you did, you can explain to them it's for the good of society if you want. See how they react.
My preferred shop for photo stuff has been B&H for the last couple of decades. I got my D850 from them, they’re usually well supplied with Nikon stuff. No. 2 is Freestyle, but that’s mainly for darkroom stuff, and you probably don’t care about that.

> VTSAX would show better performance because it includes money made from lending out securities

Correct, VTSAX would probably perform better by a small margin, but it's also hard to compare given that everyone rolls their own "Total Market Index" with slightly different stock composition. At the very least, you're getting more of your money back to you.

> how do these funds decide what percentage to return back to the fund vs keep?

Depending on how much money they want to make :)

vanguard is actually a mutually owned firmed, the only one. So they have little incentive to tax themselves. When you buy vanguard funds, you are also buying ownership of vanguard.

> Why wouldn't Fidelity keep 100% of these fees, and then charge a negative fee?

Because people have no idea how any of this works and "0% expense" rings out. They can make more money this way.
I see multiple top level comments spouting righteous indignation about this being patronizing to engineers/programmers, expecting too much of them, 1st order -vs- 2nd order effects, etc.

Firstly, this is for researchers/academics who are publishing in journals, disseminating ideas for new technology.

Secondly, the suggestion also clearly states that the work will be reviewed NOT by judging the utility in the possible consequences, but for the thoroughness of the analysis. In practice, that means that the paper's authors can not be more sloppy than the reviewer (a peer in the field who can be assumed to have a roughly similar understanding of the technology). Reviewer feedback can point out any blind spots of the paper. That strikes me as a reasonable and concrete setup unlike the FUD in these discussions.

Nobody is being asked to balance the positives against the negatives. They are simply requested to initiate a conversation about the possible negatives so that other researchers building on the idea can work towards improving those aspects!

(EDIT: Most papers/presentations already talk about the possible positive impacts -- nobody holds back on that for lack of expertise. It is only fair to ask authors to be less partisan and more thorough, as responsible researchers.)

Whether all engineers/programmers should take analogous responsibility in trying to anticipate the consequences of their work is a related, but different question, with different trade-offs involved -- because engineers are concerned more with building things and delivering practical benefits, while research (and academic scholarship) is typically more interested in a longer term view of things. Both are important but distinct questions. Please don't conflate the two points in this discussion.
Apple offers repair programs back to the 4s

This argument is a red herring. People like new things. People like things that work all the time without modification. Almost no one actually wants a phone or computer that lasts twice as long but is bulky and requires maintenance.

The disposable / non disposable distinction doesn’t really make sense. On a long enough time horizon, everything is disposable. And it’s not like you can’t replace anything on an iPhone or Mac - you can replace things like screens, storage, memory, keyboards and so on.
>> have good explanations for their underlying business models

Where could I find this? I havent seen it anywhere and have been half-worried they will either jack up prices or sell-out customers hanging like CapitalOne/ShareBuilder did. What is their short term and long term revenue model that would make their [awesome] product sustainable?

Aside: I love M1, especially after CapitalOne/ShareBuilder left their customers hanging.
This might be a bit of an insensitive comment, but alas so be it (not living up to my nickname unfortunately). I'm too used to this discussion in my own country and have little sympathy for the other side because in The Netherlands they have been wrong for 70 years now. The "we are getting too full comments" come from emotions, not from facts and I have the prejudiced feeling that in Australia it isn't any different.

Australian planologists should talk to Dutch planologists, and it'll be fine. I am culturally biased but I think it will become a problem once they reach about 200 to 250 million. The Netherlands as well: it can still grow a huge bit before it will hit a ceiling. Yes, it'll get more crammed, it just means you have to organize yourself better as a nation. But my point: if the Dutch can live in a crammed space, so can the Australians.
No for the moment for biking and soon walking altitudes are not include. But I have to figure a way to take it into account.
> Why couldn't the SD card come in a small dime bag in an envelope?

Making the packaging bigger makes it difficult for someone to steal it. If you were to put the card in a small envelope, you would have to store the card in a locked cabinet and call for an employee to unlock and hand it to you. Multiply that by hundreds/thousands of small products and employee costs would outstrip your savings for a cheaper SD card.

Do you have any recommendations on where we could read more about the hidden history of PFOAs and teflon? These days all the nonstick pans say PFOA-free, but if they were never present in the actual pan, is it just a marketing gimmick? Like putting gluten-free on old foods that never contained gluten, or bpa-free on things that historically didn't use bpa?
The issue is energy. Energy to build the robots, energy to power their efforts. Both the power and the plastics come from the same finite fossil fuel resources and will get ever more expensive as extracting that resource gets more expensive. To tackle the recycling problem we have to tackle the energy problem or we'll make no progress addressing the essential cost. The only viable thing to do otherwise is reduce plastic production and use.
HN is quite open intellectually and it's probably the only large online community I know where unpopular opinions will mostly not be buried in downvotes on sight, at least as long as they're well argued. I value that dearly. That being said it's also rather obvious that all these years later it's still more "startup news" than "hacker news", I find that there's rather strong USA-style libertarian dogma expressing itself in many discussions and shortcuts like "regulations = bad" that are meant to be self-evident and therefore not argued are annoyingly common. It's not the fact that I disagree with the point of view that annoys me, it's the somewhat condescending tone and lack of argumentation that accompanies it that's rather frustrating.

Interestingly that whole cryptocurrency epic we're witnessing is quite educative from that point of view, it makes the dogmatic "government = bad" position rather precarious and forces a more nuanced approach from either side.
