the 'post 2017' bubble truth of the answer is this:

any successful network running proof of work will become a massive supercomputing cloud where only commercially centralized entities , including mining farms, and successful mining POOLS , are able to participate in a vast network which becomes dominated by a cartel of players who can bring the COST OF WORK DOWN AT SCALE. this doesn't necessarily mean the network dynamic leads to LESS decentralizatin over time, but it sort of means it does at the 'non-commercial' level of doing work. this is WORK WORK at the industrial scale.

proof of stake is everything else, where network participation doesn't require WORK as the core of ensuring a cryptophraphic signing system for a bunch of data.

in the modern sense, work is electricity or some proxy for electricity ( proof of compute cycles in the case of 'compute' coins like golem )

Ask HN: How can I overcome my frugality and understand consumption?
I'm what would typically be called a tightwad. I'm an engineer who rarely ever has the need to pay for software.

The trouble is, when I build products, I'm unable to fathom why anyone would ever pay me for them rather than find some way, any way, to get by without them. Thanks.
As i understand it, there are new intensive organic farming techniques that are practically unknown to big ag and which produce similar yields with higher quality (by not destroying soil and ecosystems every year). I'd counter that the final death toll of Roundup and similar chemicals could be much higher any potential famine caused by abrupt cessation of pesticide treatments. Destruction of ecosystems is an externality which has never been accounted for, and sooner or later someone will pay that bill.
It very well may have been conservatory size. I've definitely run into baby grands that were much smaller.
Show HN: Empirical Eye – Data Collection and Streaming Device for ML+AI
Hey guys,

Our company has just released a sensor + computer module called the Empirical Eye. It's basically a stereo vision system + on-board embedded CPU+GPU + WiFi (plus some mounting straps).

It's meant to be easily attached to physical machines, to collect and stream data, and enable novel machine learning applications (and one day: control those machines!).

The goal with this device is to bring ML/AI to the physical world. We've made our own "visual quality control" software with the device.

We're doing a device giveaway to developers for feedback and troubleshooting, which will help us refine it. We'd love to send some out to the HN crowd (quantities limited to about 75), and get your feedback and see what you build!

We want to make life easier for running ML experiments and developing new applications. The primary motivation has been the field of robotics, but we see it as a flexible module that can be attached to any number of devices or machines, so feel free to be creative :)

We're looking to do another production run in a month or so, with a cleaner industrial design that'll look a bit more professional. Upon delivery you'll get the device's software API. It's a Linux OS not that different from a Raspberry Pi OS, and we have basic data collection + streaming scripts written in Python for your convenience.

If you're interested, definitely check out the site and sign up for a free device. Let us know what you want to develop, and ideally a quick one-liner describing your background experience.

Not if it's behind a CDN, if you were to host a website that someone might consider a DDoS target (frankly anything can be these days), then it can be wise to keep the host's true IP off the record
If you think the US government borrows money, look at the total amount and ask: who had that much money to loan? That much money did not exist to be borrowed.

> Cities like Winston-Salem, NC (the one I'm most familiar with) that were wastelands in the early 2000's but are amazing places to hang out (and shop!) now.

That specific example is an especially good one. I worked downtown in '99 - '01, and the only reason we'd ever spend time downtown outside work hours were the occasional free concerts in the summer. Apart from offices, it felt like a ghost town. Now, when I get back there to visit friends/family, downtown is a real destination. People live there. There are galleries, concerts, good restaurants, breweries, a distillery, theaters... it feels like a really nice small city. At least in the general neighborhood of the Stevens Center.
I still have no idea where this link is going to take me.

Physical activity. I.e., start going for a run 3-4 times a week. It's a great way to get your mind off of your troubles.
Self hosted email, chat, messaging, calls is the future. Individuals will own host and run their own services for these on public clouds. There is no reason for giant corporations to own these services.
Originally, it was to put regional routes in the regional airport, and long-distance routes in the long-distance airport. (As told to me by an urban studies professor I picked up at Dulles when I was a chauffeur in college.)

Similar to how in New York, LaGuardia was supposed to be for domestic flights, Kennedy for international flights, and Newark for freight. But that didn't fully work out. (Same source.)
> Why does the DoD care where the headquarters of the parent company of their contractor is located? Are they gonna pop in and ask questions about the Amazon retail site?

Don't underestimate how much of a difference-maker face-to-face is.

I've called and emailed people and the one thing that actually got things moving was just going to their dang office and seeing them in person. I don't think it matters how good the technology gets and how many VR-facetime conference call services develop, there's always going to be something irreplaceable about meeting in person. If there's not much of a significant difference on paper between you and the competition, it really does put you ahead of the competition if those meetings go well and the competition isn't doing it. Same for hosting dinners, etc.
> "Communities can elect and impeach their own mods by voting. If a mod behaves inappropriately, users can disable that mod locally as well."

This sounds like it's definitely vulnerable to abuse. Democracy is nice, but I'm not sure it's a great idea in a situation like this where it's online with total anonymity and easy to vote fraudulently.

> "Aether keeps a 6 months of content by default. It's gone after."

I often want to search for stuff that seemed unimportant at the time a year or more later. We should focus on changing society so it's not so critical of statements people made years ago when they changed as a person, this is a better solution.

Skeptical of the value of community-building that Aether can provide, it seems like a novelty product to me. What is wrong with pseudononymous communities like Reddit & HN?
"I expect the Chinese are less exploitative in their investment approach than the Europeans that acted in Africa (slavery and just outright theft was the modus operandi for centuries), yes."

This is an absurd comparison. A normal comparison of hypotheticals would be Europeans today vs. Chinese investments today.

"China has 10,000 years of documented history"

That's an even more absurd claim, wow! Actually it's LESS than half of your claimed period.

"and this is a long game, they don't seem as interested in get rich quick schemes as some other civilizations."

We're not discussing "civilizations" here, but governments. More specifically, the government of a dictatorship.
Sweden has recently cancelled all Elsevier subscriptions, so we can’t access the journals anyway (except Open Access papers)
From what I remember it was the NSA that hacked Huawei, the problem they had was that there were routers on the market that they could not backdoor as easily as products from Cisco and other Western vendors that were amenable to their requirements.

It may not be xenophobia, it might just be plain paranoia, either way there is some public diplomacy going on that is carefully crafted to get people to fear the 'enemy' hacking everything. Why attribute everything to malice? Ultimately there is good money to be made in selling routers particularly if you can get a municipality to spend proper money on providing connectivity for a city sized area. Huawei might not be a front for the Chinese army, they could be wanting to make profit from a legitimate product. They know full too well that any backdoor specials could compromise their entire business model to lose all of their contracts to put themselves out of business. Why would they run that risk?

Cui bono applies, by making accusations NSA/GCHQ can get them out of the market so that the only option for customers is to buy equipment that is hackable by them.
Denver still makes the most sense to me. Single hop to Beijing & Shanghai

Why would Amazon need a single (longer) hop to Asia, when it can already get there from Seattle?

Going to DC/VA gives it better access to EMEA.

Wow, that's... fantastic and generous, I wasn't expecting this response. The change makes this framework so much more inviting to use.

I'll note that this is very much pre-Amazon:

"In the early 1990s, the rise of the grunge alternative rock music and subculture in Seattle brought media attention to the use of heroin by prominent grunge artists. In the 1990s, the media focused on the use of heroin by musicians in the Seattle grunge scene, with a 1992 New York Times article listing the city's "three principal drugs" as "espresso, beer and heroin" [4] and a 1996 article calling Seattle's grunge scene the "...subculture that has most strongly embraced heroin".[5] Tim Jonze from The Guardian states that "...heroin had blighted the [grunge] scene ever since its inception in the mid-80s" and he argues that the "...involvement of heroin mirrors the self-hating, nihilistic aspect to the music"; in addition to the heroin deaths, Jonze points out that Stone Temple Pilots' Scott Weiland, as well as Courtney Love, Mark Lanegan and Evan Dando "...all had their run-ins with the drug, but lived to tell the tale."[6] A 2014 book stated that whereas in the 1980s, people used the "stimulant" cocaine to socialize and "...celebrate good times", in the 1990s grunge scene, the "depressant" heroin was used to "retreat" into a "cocoon" and be "...sheltered from a harsh and unforgiving world which offered...few prospects for...change or hope."[7]

Leading grunge band Alice in Chains had a song "God Smack", which included the line "stick your arm for some real fun", a reference to injecting heroin.[5] Seattle grunge musicians known to use heroin included Kurt Cobain, who was using "heroin when he shot himself in the head"; "Andrew Wood of Mother Love Bone [, who] overdosed on heroin in 1990"; "Stefanie Sargent of 7 Year Bitch[, who] died of an overdose of the same opiate in 1992...[and] Layne Staley of Alice in Chains [who] publicly detailed his battles with heroin...".[8] Mike Starr of Alice in Chains [7] and Jonathan Melvoin from The Smashing Pumpkins also died from heroin. After Cobain's death, his "...widow, singer Courtney Love, characterized Seattle as a drug mecca, where heroin is easier to get than in San Francisco or Los Angeles."[8]"

I admire your enthusiasm, but most users don’t want to think about or manage these things. Convenience and consistency of experience is the reason for giant corporations to own these services, and unless there is a compelling shift in consumer preferences, that seems unlikely to change.
I like to think about my deathbed. We can't take money with us when we die, so what's money for except to live the life we want?

So what do you want out of life? What would you do if you had a billion dollars? What would you do if money weren't a thing at all, and we all got to do whatever we want?

I would still create things. I'd write code. I'd design 3d models. I'd write. I'd climb mountains, and run on trails. I'd spend time with my family. I'd watch movies. I'd read books.

What would you do? Are you doing any of these things now? If you can identify these kinds of things, and let yourself enjoy them in the moment, you might find yourself not thinking about money for a little while each day.
I got rid of an entire large sofa buy dismantling/cutting it up into small pieces and disposing of them with my household rubbish. A circular saw would make light work of a desk like that, but a handsaw would work fine too.
What is it about the millionaires that makes you want to be one?

Freedom from having a boss? Not having to work? Fast cars? Flash apartments in trendy locations? Bragging rights? Feeling of "winning the game".

Ask yourself honestly will you still have some kind of obsession even if you made millions. Its a cliche the 70 year old billionaire businessperson still working their ass off.

In a nutshell get to know yourself and your motivations. Reflect.
Short answer: Yes, but it depends.

Yes: I believe everyone would benefit from leaving their comfort zone and venture into more DS to expose themselves to some non-trivial work. Don't get me wrong, there are plenty of challenges on writing a working CRUD system from the bottom up but facing scalability, consistency and fault tolerance issues is a different word, and most software developers don't give a damn about performance. That's usually what happens at startups or small companies(I've been there several times). A small and focused team builds a working product, and suddenly they need to bring more experienced engineers to help then scale it once the cooking recipes from the internet aren't serving them well or because the leadership won't let the team engage these challenges. So my first advice goes here if your company has such problems try to expose yourself to them.

Practice and theory should walk side-by-side, you can read the entire library on distributed systems but still be mediocre when facing real problems because you've never encountered those problems in practice. Use the books and papers to give you a direction to where you should point and do your homework. Consistently paced challenges and exercises gives you volume(consistency) and helps you build experience. Build your glossary of concepts, nail your difficulties and once you understand the basics, go read and implement CRDTs in Rust by yourself :) - I'd also suggest you to try following a book on your own pace first before committing to any formal education. Try to find a mentor within your friends who can give you more advice's and peer review your work.

Now the sad part: Unfortunately when shifting expertise even within the same career, you give up on several years of your experience. You will look less appealing to recruiters and companies because you just turned yourself into a JR. Distributed systems engineer w/o previous experience, and those are pretty hard to find out there. If you can live with that(both checking our ego and financially) and be humble enough to accept your new position - I'd recommend you to embrace it.
Why? Easy, people kept figuring out attacks so they kept working on better designs. Figuring out a solid PoS protocol is nontrivial.

A few days ago Vitalik went through the history of Ethereum's proof of stake research at the annual Devcon, if anyone's interested: https://www.youtube.com/watch?v=Km9BaxRm1wA

At this point they're pretty happy with the protocol, the spec is mostly written, and eight teams are working on clients. The new design includes blockchain sharding for about 1000X better scaling.

Regarding your analogy, regardless of protocol you have a certain amount of "weak subjectivity," in that you at least have to know what client software to run. Otherwise you might be accepting invalid blocks.

The attacks you mention can be handled by requiring stake to be locked up for several months, and slightly broadening the subjectivity you accept to include a periodic known blockhash. You have to use off-chain social means to find out the correct recent hash, but you have to do the same to find out the correct software to run. https://blog.ethereum.org/2014/11/25/proof-stake-learned-lov...
Given that this training data basically gets loaded into neural nets, etc., can it be said that in some indirect sense these data labelers are actually driving these cars? Are we still just building the mechanical turk?

To be it shows how far we still are from biological intelligent systems. I don't recall having to point out what an apple is to my daughter more than a few times. Watching children learn is breathtaking. Even much simpler brains like those of rodents or cats are far beyond anything built so far in silico.
Do SoC's even matter that much anymore. The article is full or nice graphs and numbers, but at the end of the day, we're at a point where everything is fast. These days, the improvement in processing and memory are negligible. What matters much more to me is things like battery life, computational photography and new features that actually make a difference in my everyday use.

For example, with night sight, I actually took a bunch of pictures during Halloween, whereas otherwise I wouldn't even have tried. With call screening, I actually get to check all those scam calls I get every day. Wireless charging is also a pretty nice feature to have.

Things like that are much more impactful in my everyday use of a phone than having a 5% faster CPU.
Credit has been nearly free for a long time. Cheap money increases buyer leverage, which translates into higher prices. Plus large numbers of immigrants in big cities a big factor. Buying a home is generally #1 focus of new Canadians, They’re a big enough block of market participants to move prices.

Lots of other factors of course. I imagine since R/E market is hyper local, country-wide stats won’t really give an accurate picture postal code to postal code.
Chicago's preferred Amazon location is Goose Island, part of the newly expanded downtown skyscraper district.[1]

The city recently approved 18 new skyscrapers for downtown, including 12 for the proposed Amazon site, with an included professional soccer stadium.[2]

I don't follow the "very positive cascading effects" line. How is low fertility rate and women being free to do other things a positive cascading effect? Historically, it makes families more unstable.

Edit: I'm not saying women working is a bad thing. It's good on many fronts. But I feel the ripple effects are not positive.
Just get your shit together
Sorry, I didn't mean to imply that. My point is that these companies ought to be able to sell 'voting machines' that suck, and we ought to be free to not buy them. They should not be free to make false claims about them.
Being a sovereign user of your own currency is pretty great.
If I was in your situation I would start thinking along the following lines.

1. Tell yourself that it is okay to feel uncomfortable. This is uncomfortable feeling that you're not in control, that you're not making enough, that you're going to miss your one shot. This is the first step at reducing the anxiety of it.

2. Start to remove distracting consumptions. Social media, articles, news, etc. Spend time just being with yourself and appreciate the quiet. Put your phone on flight mode at night and charge it in a different room, get enough sleep.

3. Expose yourself to new perspectives. I have found the following audio books to be instrumental is figuring out how to be happier without greed:

a) A Guide to the Good Life: The Ancient Art of Stoic Joy

b) Man's Search for Meaning

c) The Power of Now (I'm only about 1 hour into this one, but it's made me think)

4. Start a new routine to break the habit of your current ways of thinking.

5. Meditate to help you regain control of your reactions - become reaction aware.

6. Don't look for whole solutions, progress happens in tiny steps and just keep exploring new ways to approach how you feel, how you motivate, how you enjoy the today. Sometimes it's the smaller things that have more profound effects.

7. Start measuring your progress in years, derived by small daily improvements.

I appreciate the above advice might not be for everyone, but it's something I'm going down and enjoying it very much. You already reached a fundamental point, to bring out of your subconscious how you really feel. Now you can consciously reprogram how you want to feel. Well done!
When groups of atoms are cooled to such unfathomably low temperatures, they stop moving as individuals and meld into one big "super atom." Tens of thousands of atoms suddenly become indistinguishable from one another, slowly vibrating on a uniform wavelength that can, theoretically, pick up the tiniest gravitational disturbances around them.

Why should this be called "super atom", just because all atoms behave the same? If I have a bag of indistinguishable rice corns, they don't suddenly become a single "super rice corn".
Roads to transport it faster out of the country, airports that aren't used, Chinese labor funded with domestic debts, lended by the Chinese bank.

Here's the Wikipedia article on laser cooling: https://en.wikipedia.org/wiki/Laser_cooling

Its explanation is a bit too surface level for me. Anyone have more details on the mechanism used for this experiment? Would they have used Doppler cooling like is sometimes done on Rb-85?
Actually there are formal proofs for the properties of various PoS designs, both in the Ethereum research community and outside it with academic projects. It's a fairly active area of research.
Yes, because I want my grandmother to self host her email on a server. Sure I could do it for her, but what if I died first? It’s not as cut dry as you make it out to be.

EDIT: I get some grandmothers/fathers could be proficient in this, and power to them for being so. Mine are not, and I’m not going to waste their time teaching them when they’re mostly concerned with living out the remainder of the lives with family, etc.
You had my hopes up for a minute there, until I checked portability…

malloc_usable_size() is a GNU extension, so usable on Linux. MacOS has malloc_size().

One web page [1] says the GNU one is about 10 cpu cycles and the MacOS one is about 50 cpu cycles, so not the end of the world, but maybe a little long for string length checking.

I didn’t check any BSDs and I have to wonder what the effect of changing allocators in Linux has. Certainly they could have a performance impact and possible a ‘does not implement’ problem.

Why is this near the bottom of the page? Seriously.
Except for the weather, Chicago isn't a terrible choice. The problem is that no matter how great the city makes itself, it's still in "flyover" country. That's a difficult stereotype to break.

Chicago and its mayor worry too much about being a "world class" city. You know what world class cities don't worry about? Whether they're a world class city or not.
