I'm sorry you feel that way but I think you're being too negative when you say "nothing productive" has been done or that pilots were a miserable failure.

Yes, things failed but at least you know more about the market, how to (not) build things, etc.

Consider pivoting into a similar area using your newly gained skills instead of shutting down. Also, if investors feel like the money should continue to be spent, that's a business decision and you shouldn't feel bad about it (unless they are super ignorant of business and invested for emotional reasons. If so, then educate them and it's their decision in the end).

Best of luck!
It's my understanding that a lot of self driving cars use LIDAR to localize themselves in a 3D map, so a 2D representation wouldn't work. Then there's bridges, tunnels, and so on. Maybe a better example is flying drones, there are consumer drones available that keeps track of the surrounding and the user. In this video[0] it looks like they use a sparse grid of some kind, but wouldn't that be a tree?

The problem with a grid is as you mention the cell size. If instead of cars we use a different example, like large scale photogrammetry, a small cell size is desirable, because you want as much detail as possible, but you might reconstruct a small city. With some tall houses you need a large grid in the z-direction, even if most of the volume will be empty, suggesting that a tree would be the better solution.

Are there any real life examples of how this problem has been solved? As far as I can tell, this project supports point clouds and mesh as the main data storage, and KD-trees from point clouds to do operations on it. I've found, but never used, Voxblox[1] and OpenVDB[2] that looks promising. Voxblox is made for robots but looks like it might use a lot of RAM for larger spaces, OpenVDB is made for visualization but maybe works for other things too? I don't really understand how it works though.

My proposal stems very much from nearly identical thoughts that you just described!

Just posting to say I have read your comment, and will most certainly edit this comment to reply tomorrow!

I will probably also want to be able to contact you (by some method acceptable for us both, email? IRC?) if I ever rewrite this in a more accessible format, or perhaps to collaborate on this subject?
It sounds like they literally took the brains from slaughtered pigs. I don't know why they wouldn't have processed the meat as normal.

> Brains rescued from a slaughterhouse had their circulation restored with a system of pumps, heaters and artificial blood.
>What the is that "people of color" thing has to be mentioned here

Probably because marijuana laws overwhelmingly punish minorities over white people. Just a quick Google search shows some numbers for New York, where 80+% of marijuana arrests in 2017 were people of color, and less than 10% were white.

You’re ignoring the method of killing the animal for food. It’s not just “killing them for food”. It’s the entire industrial process of slaughter at scale. Look into it sometime.

I mean building up geometry from scratch using different kinds of depth sensors in an expanding environment of unknown size. The data is probably in the form of point clouds to start with, but you can't really store them sequentially if you want to do any operations on it, like loop closure or rendering.
That level of inhumanity generally _is_ accompanied by "blood on the streets", as you put it in your original comment.
CloudFormation supports YAML templates out of the box: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGui...

It's way nicer than JSON, especially w.r.t. functions. It's also compatible, so you can load JSON templates into e.g. a Python script and serialize them to YAML. I did this to all our templates pretty much as soon as it came out.

I have used cfndsl and loath it. If I need more complex variables than CloudFormation supports, I rather use a simple templating engine like Jinja2 or ERB than a Ruby-based DSL.

There are a couple of ways to cut it up, for instance you could segment by:
Mood

Form

Period

Instrument

For me, I started with solo piano mainly, and some light chamber music and worked through periods (at a natural rate rather than any rigorous scheme). I found solo piano somewhat easier to analyze by ear and deliberately stayed away from things like symphonies as they were way too complex to appreciate to a depth that I am personally inclined.

Once I developed an ear for periodic styles and musicianship, it became natural to branch out into orchestration and more composers.

In terms of solo piano works that are famous:

Bach Goldberg variations/preludes and fugues/english and French suites

Mozart piano sonatas k310-333 are decent.

Beethoven piano sonatas pathetique, moonlight, les adieux, appassionata, waldstein (maybe also hammerklavier)

Chopin nocturnes, waltzes, preludes and sonata 2

Debussy - arabesques, suite bergamasque, piano pieces, preludes

That would be a starter :)

Space Decentral: Using Blockchain Tech to Democratize Space
There is a lot in this essay that is problematic. I'll offer just two examples:

"What exactly does science tell us about the idea of a human nature?"

Science can't tell you anything until you have a philosophy of knowledge which defines a thing called "science". So the argument becomes a bit circular here.

This is worse:

"If we take evolutionary biology seriously, then we certainly should reject any essentialist conception of it, such as Aristotle’s."

That is a large if. Here are some unsolved problems in evolutionary biology:

1. Why do people become gay?

2. Why do people adopt children who are unrelated to them?

3. Why does such a large percentage of the population suffer mental illness?

4. Why do people engage in acts of altruism, helping those they are not related to?

5. Why do people believe in gods, and why do they make sacrifices to these gods?

A famous argument against evolutionary biology was made by Richard Dawkins back in 1976, in his book The Selfish Gene. As Dawkins says in that book: "We can rise above our genes; indeed, we do every time we use contraceptives."

Before we "take evolutionary biology seriously" we need to carefully consider all of the arguments against it. And since so much of this article depends on "take evolutionary biology seriously", the whole article is weak.

Mind you, I believe a strong case can be made for a human nature. But I wouldn't build that case on evolutionary biology, without first addressing the known limits of evolutionary biology. A stronger case could be built if one first argued for independent agency in the processes arising from genes. This is the "ghost in the machine" argument. But that argument would have something in common with the philosophers who are being criticized in this article.
"How about people who know a field and are in the field are more likely to commit a crime in it? I am sure the number of blue collar embezzlement is dominated by plumbers/electricians etc."

I think you entirely missed what the article said. The claim was not that most white-collar crime is committed by managers, but that the individuals most likely to commit a crime were either b-school grads or veterans. In your example, this would be like union electricians committing more fraud than their non-union counterparts.
Maybe respond to an actual person saying a specific thing, or state your own opinion, but thoughts about some mish-mash person that doesn't exist aren't even odd, they're just nothing.
How do you define consciousness such that pigs have actual consciousness on their own (without having spent some significant amount of time with humans)?
Sort of - there's a jQuery API that does content sniffing called .data(), it's for storing and retrieving arbitrary data on elements. The problem was that they used this API to read from an element where they should have used .attr(), which returns a string.
> Hindley-Milner has problems with inferring types in the presence of polymorphic recursion, and a user provided type annotation is usually necessary.

Strictly speaking Hindley-Milner never requires type annotations. It can infer the type of any well-formed expression. You must be thinking of some extension of HM (of which there are many).
What you described sounds exactly like the arc of Facebook, only forced to its natural conclusion at a much faster pace.

FB started as a network for college students. Then once it expanded to the general public it turned into a gold rush of businesses trying to grab attention. FB slowly turned into the AOL of its day--a captive portal where people largely ignored the rest of the web. Why check the news on a publisher's site when I can just scan headlines while waiting for my friends' updates?

I remember a time before every website decided they needed a Twitter/Facebook button, before coffee cups were plastered with those app icons next to the store's brand. The whole thing seemed strange and desperate as it was happening.

Now the lag between "cool new social medium" to "spam/meme repository" is fast enough that I don't even have to bother. Anything fun and user-focused on the web ends up getting bought and repurposed to serve ads.

Wren is a gorgeous accomplishment. The speed gains are thanks to careful design, such as emphasizing static definitions of classes, private functions, constant slots, and computed jumps.

If anyone asks you "what does good code look like", Wren is a great example of thoughtful tradeoffs and excellent explanations.
You can definitely do this.
Start with Mozart, move to Beethoven. Wrapping your head around classical styles is easier when you directly compare the Classical and Romantic styles since they are quite different. That gives you a foundation to understand other forms.
The problem with that is that most of the CO2 emissions we depend on as individuals are beyond our control. Things like the emissions generated in growing, processing, packaging and transporting the goods we buy, our food and clothing, our mail, the utility resources we consume, the services we depend on, public transport. Yes we can do thing in our daily lives but in reality it’s a tiny fraction of our actual CO2 footprint. That’s why societal and industrial level action, and therefor public policy is so important.

The biggest environmental issue we can affect in our daily lifestyle is recycling and reducing household rubbish. It’s another important issue and one where we really can make a difference in our everyday behaviour.
Hmm, but killing plants and fungi is totally OK then, yes?
But obviously that isn’t in any country’s interest
That situation isn't actual harassment, at least not in the legal definition of the term as long as you are talking about an out of work context and these guys just approached you once.

Is being approached by a beggar harassment? Is it these individual guys fault that many little annoyances add up to be a big headache/borderline harassment? It's not like clairvoyance is an actual thing, so what are you actually blaming them individually for? And what could they, individually, ever do to prevent that situation?

The expectation you are having here is that all males should instead always be passive and never approach a female of interest because she might or might not have been approached before and thus feel harassed. Doing this "equal" would mean females should also never approach males, where would that leave us?

Tbh there is no easy solution to this because there are issues for both sides: Females getting dogpiled and males usually getting nowhere without taking opportunities leading to said dogpiling.

On a more practical note: There are subtle ways to prevent at least some approaches from happening and deflecting them somewhat effectively. Like wearing visible headphones when in public, instantly, but politely, declining the approach with body language by keeping a steady pace of urgency and slightly shaking the head.

With time this is bound to get better, at least if eroding of societal role expectations happens equally for all genders and females actively approaching males becomes something that isn't considered "out of the ordinary" due to its sheer rarity of happening. Imho that's something that very likely will require a multigenerational effort.

It’s been in my head for a while - finding an area with good weather and a farm landowner willing to sell. I would love to find a developer with core competencies - we used to build cities because of common interest. Why can’t we do it today?
I hadn't even heard of MoviePass until seeing this posting at HN. I don't watch movies, and MoviePass sounds ridiculous.

I was critiquing your comment because it had no substance and seemed anti-intellectual. It actually sounded like what you see people write to defend bull-crap like MoviePass, as in "Don't like Facebook's terrible actions? You don't have to use it…" used as an argument against people complaining (as opposed to an argument that people should leave Facebook because the complaints are legitimate).

Maybe it was just a misunderstanding. Seems you didn't do a good job of making your initial point, and I replied to the words I read.

Look at total tax bite and I think you'll generally find that taxes in cities are higher than in suburbs. I've lived in lots of cities and suburbs. I always get more for my dollar in suburbs. In cities, there are more legacy costs in pensions and there is more corruption.
This is a significant part of what attracted us to Fort Collins, Colorado. It's not as small as you're describing, but much of the city is walkable, including the downtown area and dozens of surrounding blocks, along with multiple paved bike paths, etc. It feels more like a city built for humans than most of its size in the states.

> Generally everything you're saying about Linux package management vs Homebrew is the opposite of my experience. A coworker uses Linux for his machine and apt's packages always seem out of date or he has problems installing things, whereas Homebrew always just works.

A TALE OF TWO HOMEBREWS: the collection of build recipes (a.k.a the repos)

The second piece of Homebrew, which deserves to be compared to _distinct_ counterparts in the Linux world, is the ecosystem of homebrew-core, the taps provided by the community, and so on. In these respects, Homebrew is more comparable to a distribution's repositories than its package management tooling. Some Linux distributions are based on very up-to-date upstream sources, much like Homebrew. Nixpkgs, which is a collection of packages for the Nix package manager (usable on NixOS, GNU+Linux distros, and macOS) tends to have the same versions of packages as homebrew-core does— it's very up to date. But many Linux distros and users prefer to use older versions of software (which still receive security updates!) so that other users can suffer all the usual pains of early adoption, and work out some of the kinks for them. Some users just don't like dealing with frequent updates. Ubuntu is often used this way, with users recommending and installing the ‘long term service’ releases, which receive infrequent feature updates, but regular security updates. One unfortunate consequence of this strategy for gaining stability is that it can significantly complicate installing the latest releases of software, and that's what I suspect your friend has run up against.

Here, Homebrew is very similar to the repositories of many Linux distributions (like Arch, Gentoo, or perhaps even Debian Sid), and very dissimilar to others (CentOS, Red Hat Enterprise Linux, SUSE Linux Enterprise, Linux Mint, Ubuntu LTS releases), and I don't feel that there's a fact of the matter about which way of doing things is ‘better’. I will say, however, that Homebrew has a thriving, active, and friendly developer community who are constantly adding new packages, updating existing ones, and working to improve the quality of the packages in their repositories. Homebrew contributors and users should take pride in that.
So what's your proposed solution? "The War on Drugs" is actually a "War on poor people and minorities". Far more harm has come from locking people up for non violent crimes that disrupts families, gives police more power, and makes it almost impossible to find meaningful employment after being released.

There have been plenty of studies showing poor and minorities get treated much harsher by the "justice" system.

It's not really that.

Legalizing drug use and abuse reduces overall crime, drug usage, and damage done by drugs through more help, less stigmatization, clean tools, clean drugs.

It's literally the dream solution, however, politicians are too dumb to understand that.

It's proven scientific evidence, see Portugal.
They aren’t? In Chicago at least the opposite is mostly true.
Well that explains wide variety of friendly spiders that exist in Australia to this very day. :)
Yes. There’s a huge difference between a sentient being and a plant. I don’t think anyone seriously believes that these are morally equivalent.
I don't feel like I fully understand it.
The crimes there aren’t taking the drugs, they’re the actions which harm and endanger others. Focusing on those crimes makes most sense. Under the current system, we prosecute drug use, distribution and sales way more than we prosecute the actual crimes that harm others.

It’s completely backwards. You should be free to alter your cognition, but also held responsible for your actions.

Orthogonally, there are also many other mental health and non-mental health related public health issues we should continue to pursue, regardless of the current state of substance legalization.

Car density plays into this a bit.

It’s not really possible to separate the egg and dairy industries from the meat industry. What do you think happens to chickens or cows when their production levels start falling?
Have you ever been on or near a farm ever, or even talked to (not shout at) a farmer? Pigs squeal for no reason and they squeal all the time I'm sure non-farmers assume squealing means pain.

I live in a rural area with lots of farming. A few people I know come from families that raise pigs and no they do not torture them. Even to the point of having a controlled access entry to the barn to prevent disease coming in from the outside (disinfectant tray for shoes).

It's hard work to maintain and raise animals for food farmers aren't going to spend time and effort torturing pigs which are their income. No business person is going to damage their product for kicks. A wheat farmer doesn't drive over his crop and flatten it. Fishermen don't throw dynamite into the water for fun.
