One of the big questions is whether we can extract these minerals from existing devices that are out of use/have been disposed of. Ideally, that means that we are designing new devices with disassembly in mind. Everyone from Apple to Huawei is talking about doing this, but the proof will be in the pudding.

Some of the comments are slightly inaccurate. We actually don't know where all the deposits are, and there was just a large discovery of rare earth elements off the coast of Japan. Much rare earth extraction has been happening in China because of relatively lax environmental standards that have reached back decades, so the US, Australia, and many other countries with deposits can't compete due to the costs of labor and complying with environmental standards and regulations. Mountain pass is one of a few deposits in the US, and happens to be one of the larger ones that is sitting idle. There are lots of mines globally and could be more, but economically they need to be attractive.

Copper is another interesting element. It is exceedingly hard to extract from existing devices because it is buried inside the chips, boards, etc. You can recover about 25% of the copper in a device, or about 3% of the total mineral content of a device when you extract copper. Widespread copper mining has destroyed parts of the Atacama desert in Chile and is a really nasty process.

Finally, work has been going on for a long time to replace rare earth elements or dramatically reduce how much is used. In some cases, you need small amounts because you need those f-orbital electrons but you can get away with using creative coatings instead of large volumes of materials. In other cases, you can replace them by multi-layering other materials to approximate their performance. There are huge opportunities here, but we are a couple decades away from seeing any real sea change in what our devices are made of.
I’ve worked with a GA implementation before which I don’t recommend if you want to own your data or if you want unsampled, detailed logs. I’ve also seen a full end to end implementation that uses server log shipping to s3, log parsing and complicated ETL processes which I also don’t recommend due to the sheer effort it would take to build.

I’d say go with something like Matomo (formerly Piwik) https://matomo.org. If you wanted to build your own, I’d suggest keeping it simple. Look at Matomo’s architecture and replicate https://github.com/matomo-org/matomo.
Looks cool, but the problem I keep coming back to everytime I switch to Linux is... Why? Windows works just fine for me. I use my computer for a browser, video games, .NET development, and web development.

I've spent many, many hours over the years using and configuring Linux, and I keep coming back to the same conclusion.

Yes, Linux has much better privacy than Windows, but for many people, that's not a strong enough reason.

The reason it's showing those interesting paths is because it's plotting the relative motion of the planets with respect to the Earth.

So visualize the moving Earth in the center of each image with the other respective planet moving relative to the Earth. Since both are moving and rotating about the Sun we get these interesting motions with a lot of structure.

This is the theory of epicycles which was the main theory of the motion of the planets before the heliocentric view became prominent.
Stem and Engineering – All the Answers
I am one of those people who is opposed to the death penalty but in favor of life in prison without parole. In my thinking this punishment is/should be reserved for the worst and most heinous crimes against other people, whether that is murder of or violence against another individual or perhaps also white collar crimes of sufficient scale. I see nothing wrong with depriving a criminal of their own life and freedom if they consciously did the same to others. They also don't have a potentially limited period for exculpatory evidence to arise like with the death penalty.
>>What I don't understand is how people can be against the death penalty but yet be totally OK with locking people up for the rest of their lives.

So I'm one of those people. It's simple really - death penalty is permanent, while life imprisonment isn't. Yes it sucks that sometimes we might have to release someone who spent 30 years falsely imprisoned - but it's sure a hell lot better than finding out that there is no one to release because the person was executed a decade ago. And secondly, I just don't see any need to execute people, the risk vs reward is not worth it.
In Uyghur territories yes but you don't tend to "hear" about this happening elsewhere. All that's missing at this point is people being put into black bags never to be seen again. The legislation around extradition to China will address that.
> This is the correct way of thinking to move forward.

I guess it depends. In case of rare earth elements supply problems we will just skip the next iPhone upgrade cycle, wait until supply chain readjusts and buy the next iPhone version a couple of years later. No big deal. This cannot be said about all (eco)systems.

Just to take a random example - Aral Sea [0].

"The Aral Sea is considered an example of ecosystem collapse."

"...As a result, the land around the Aral Sea is heavily polluted, and the people living in the area are suffering from a lack of fresh water and health problems, including high rates of certain forms of cancer and lung diseases. Respiratory illnesses, including tuberculosis (most of which is drug resistant) and cancer, digestive disorders, anaemia, and infectious diseases are common ailments in the region. Liver, kidney, and eye problems can also be attributed to the toxic dust storms. All of this has resulted in an unusually high fatality rate among vulnerable parts of the population: the child mortality rate is 75 in every 1,000 newborns, and maternity death is 12 in every 1,000 women."

And these people cannot just "adapt to changes" and move to new territories, because somebody is standing on the border with a gun. Tell them that "economic" thinking is the way "to move forward".

All I am trying to say it's not so black and white.

I'd argue against this solely based on the deflationary costs within computing. Factor that in, and the outlook for twitch looks great.

Article readers -> Video consumers(YouTube, Facebook etc)-> livestream (initially games and now anything)

Streaming games might be the first high value use case but I can def. see twitch gain traction in other niches.

I don't know how expensive it is with Google/AWS, but I'm paying about $1.50 per TB at my non-cloud-host (vs their $12500/TB), so if it comes down to it, they need to outspend me by multiple magnitudes. Sucks, but still cheaper than losing customers due to hyper-annoying Recaptchas, and I doubt that somebody is willing to stomach $12500 cost to make me suffer $1.50 ... I'm sure there would be more efficient attacks ;)
Awesome to hear that! Thank you so much for your work!
The angst usually centers around management being paid enough to hold on to the laid off people so they can develop their skills and work on 20% type projects. As things are, they leave the industry after a few rounds of it.

It's shortsighted. They let many of the people responsible for that wealth float off to more stable industries so a few people can get rich far beyond their contribution.

On another level, why should the state have a list of my accounts at all? It already sees all the accounts at banks within their territory. They don't need to concern themselves with accounts outside their jurisdiction.

In the context of income taxes, it should be enough to report total earnings, regardless of which specific account holds them.

Besides markets adapting and finding new equilibriums, there may still be ressources that run out and ultimately can't be replaced, similarly how the Easter Islands were deforested and life got permanently worse [1].

Maybe rare earths can be substituted in phones, and other technological progress makes up for the loss. Either way, the same market forces itself do nothing to stop the coming climate catastrophy and would happily find a new equilibrium with large parts of the planet not being livable. That's why "ecological thinking" is important.

The quickest and easiest thing to do would be to hook up Segment or a similar system (heap analytics, google analytics, etc). I would stay away from GA given my own choice though. It’s free but google won’t give your own data back to you without an enterprise agreement which runs 6 figures minimum. For open source there’s snowplow, which I haven’t used but many in the data community do.
There is nothing unknown in the article. You can do this at home as well. Is very well explained how it works. For start I would suggest you get technical of how Yagi antennas work, it's the same principle coupled with cavity resonator + membrane movement used in a microphone. In the end you get your high frequency beamed back modulated by the sound. And is not AM modulation, is FM modulation. But what article indeed lacks is the power required to get the device working properly. In my experience I would guess at least 1KW would've been beamed directly at the embassy walls when Soviets were doing their surveillance using this device.

> I would guess that those who have learned the language have a more logical, grammar based structure and write more deliberately.

We have our own native languages with their own idiosyncrasies and we don't make mistakes like "could of" or "you're/your" in those languages. There's just no excuse for those simple mistakes...

Greek has 5 very common and 1/2 rare spellings for the sound 'i' (as in 'kit'): ι, υ, η, οι, ει /υι,ηι

Imagine if people who can't tell you're/your and write 'could of' had to face this reality...
They are lazy ignorant people and the other native speakers need to stop enabling them and making excuses.

<edit>

I'm not actually sure if 'ηι' exists, google is showering me with irrelevant results.. in any case, furthermore, there's

two ways to spell 'e' (as in bed): ε, αι

two ways to spell o: ο,ω

two ways to spell the av/ev sound: αβ/αυ , εβ/ευ

two ways to spell the af/ef sound: αφ/αυ , εφ/ευ

and more. Maybe the difference is that all this crap makes you actually pay some attention to the language if you don't want to embarrass yourself
C compatibility is one of the original design goals for Swift and is used extensively for the Linux version, for making Swift wrappers around existing libraries, and the Objective-C bridge on macOS. If using Xcode, one would use a bridging header; otherwise, one can use Swift Package Manager to wrap C libraries for use in Swift projects.

Swift recently gained the features needed to call Python code. You can either use the Python module from Swift for Tensorflow or the PythonKit library, both of which allow calling Python code from within Swift.

The features used to allow calling Python from Swift can also be used for other dynamic languages, so there may be the ability to call Ruby and other languages' libraries in future as well.
STDP based SNNs don't take much secret sauce to function reasonably well for basic tasks[1]. Some people have even started to apply reward modulated STDP to the problem which is nice to see since it's a more complete version of STDP[2]. Even so, the amount of research in the area is tiny. I agree that you need to figure out the whole working algorithm before trying to scale things up but to do that you need a research base and currently that is difficult because running large SNNs is very slow for an average researcher without access to specialized hardware. The primary factor which kicked off the deep learning revolution was the idea that suddenly you could train a DNN 10x faster using a GPU rather than a CPU. Without this revelation, most researchers just wouldn't bother because DL research took too long. GPUs are common and lots of people had access to them. SNNs obviously can be simulated on any CPU but for large models it's incredibly slow. SNNs have an incredible amount of potential paralellizeability but all of it is in the form of a massively asynchronous system where the order of events is critically important. CPUs and GPUs are unable to take advantage of most of the potential speedups inherent to this structure outside of specific cases where you have groups of non-interacting neurons. Due to the event based rather than signal based nature of SNNs, batched training also seems to be substantially less effective than in ANNs further complicating training.

Capitalism works, because democracy makes it palatable. Without democracy, capitalism would surely have collapsed before us. It's how some socialists consider social democrats their true enemy, as they have prolonged the existence of capitalism, through incremental change making it more palatable.

In essence, in the immediate aftermath of the bourgeois revolutions of England and France, lord and serf were simply replaced by capitalist and labourer. Often to a point where they became indistinguishable. Sure, in a capitalist society, compared to a feudal society, your ownership of production matter more to circumstance than to nobility.

Or at least, that's the sales pitch.

So if democracy keeps capitalism artificially alive, is capitalism doing the same to democracy? That's harder to answer. But if capitalists keep on automating their production to the point where there are no labourers left, then who is to pay for the products they produce?

Marx and Engel may believe that capitalists were creating the very force to bring them down, but they may not be the labourers, but rather the robots with which they replaced the labourers.
I love glitch. I use it for lots of glue pieces in personal applications that I'm just playing around with. I'd say that every piece of code in the past 2 years that isn't related to work has been somehow connected to a glitch project/deployment.

The US-Saudi relationship is a strategic alliance. In this complex world there are few chances to ally with, support, trade with, or align with ONLY free and democratic countries.

The US is aligned with the most free and democratic state in the Middle East (Israel) as well as one of the least free (KSA). [0] The NATO alliance sees the US formally aligned with one of the world's most free democracies (Norway) and a country that is judged as not-free at all (Turkey)[0].

Unless the US sticks to supporting - in words, with trade, and in security terms - the very small handful of countries that can claim to be entirely free and democratic it's going to get its hands dirty siding with people and states that it would, in a perfect world, prefer not to.

The hourglass had been irrelevant for quite a while when it was (successfully) employed as a UI metaphore. I wouldn't assume pens to become obsolete any time soon, either.

And whereas filing cabinets do fall out of fashion, the metaphore is deeper here - we will always arrange our possessions in some sort of hierarchical structures. Whether it's a filing cabinet at your office, or drawers and cupboards in your kitchen.

This concept is guaranteed to have underlying physical representations, even if some particular use cases will come and go. Not quite so with tagging (suggested by the author as an alternative for folders).

Tags are inherently more abstract. I don't really have a clear-cut, real-life way of associating my possessions with a tag cloud, whereby I could plausibly filter out all the #electric stuff I own, or #healthcare stuff, or both at once etc.

Thy're not stable over time, and so would be unable to maintain a coherent sequence of behaviour or 'thought'. Human brains are the most heavily armoured and environmentally controlled part of our bodies because complex behaviours are incredibly sensitive to environmental interference. Something as totally open and exposed as a bare sludge or ocean currents couldn't maintain sufficient coherence.
That's true for books (and public libraries, a status which the Internet Archive holds in the US, if I'm not mistaken; that doesn't change their status w.r.t. the rest of the world, however), but I don't believe you can directly transfer rules regarding books to websites.

The Internet Archive publishes the content, they don't use a robots.txt, canonical-tag (they do set a link-header) or robots meta-tag asking search engines not to index their version. For all intents and purposes, it's just a copy of your content published on their website.

I understand their goal, I'm not opposed to it on a fundamental level, but I do believe that the choice of participation should rest with the content creator.

Yes, I think 300 is an estimate of the number of cycles for a load from RAM: 192 ops / 300 cycles == .64 ops / cycle.

I'm not sure whether the calculation is true, though. Why can't the post-load µops be executed and retired, and the ROB refilled, and then more µops executed? I'd think the calculation would only apply if everything was somehow speculative and thus nothing could be retired, but I don't see this being a common occurrence.
