Ugh. Be very precise and tell me, what does it matter? What about the story would change if he'd used super extremely precise numbers? How would the conclusion change, exactly?

Does the correct number for solar power during totality explain why it gets cold before it gets dark?

The article was not wrong, it was an approximation, which he stated clearly. Did you perhaps not understand this sentence: "Anyway, there is never really "zero" radiant energy to detect. In reality there's always some kind of background noise, maybe at -90 dB or so."?

If he had used the correct number, you would see that it is approximately 0% power. Again, and I'll state it as fact now rather than rhetorical question, the article was accurate to more than 3 significant figures.

BTW, the discrepancy between night time levels and the darkness of totality is due in part to atmospheric scattering during the eclipse, so you're introducing a red herring.

> he could have definitely plotted that

Given that the heat plot goes from 0% to 100%, and that the brightness plot goes from -70dB to 0dB, will you estimate for me how many pixels in both plots would be different if he used really precise numbers for solar power during totality? My current estimate is 0 pixels would change across both plots. Do you think the number is higher? If so, why?
It demonstrated clearly that Kim can hit any town in Japan and surrounding territories if he so chooses. The Japanese government went to some trouble to disseminate that information via SMS. If they could shoot down that missile and not terrify their own population they would have done so.
It's not against the law to have a monopoly - it's against the law to exploit having a monopoly to enter another market.

Microsoft was seen to be exploiting it's consumer OS market share to gain a monopoly in the browser market and the productivity software market, AIUI.
Yeah but, hydrologists have a joke: What's the first law of hydrology? Water runs downhill. Which is funny when you're a PhD accustomed to wrangling ridiculously complex multidimensional partial differential equations from fluid dynamics, to say the same thing.

But I suppose what ruins any ability to rely on "the first law of hydrology" here is the fact that the whole area is so flat, and so low, and so paved.

Data science on a chromebook
Will these type of devices ever offer any sort of surround-sound functionality, for watching movies/TV? Even the Apple HomePod, which is a high-end speaker, doesn't seem to be pitched this way. Apple touted the ability to pair two of these together, but two speakers (at least conventional ones) don't offer surround sound.

And they're so expensive that most people wouldn't want to buy four of them. Amazon Echos, on the other hand, are cheap enough that buying four of them could be lower-cost than buying/wiring conventional surround speakers. But is surround sound in the offing for the Echo?
This is already happening. Why else would the SEC issue something about it this early into its course?
One of the reasons people have shifted away from MNIST is that it's simply too easy. Single channel, small image size, few classes, etc. Unfortunately, this does not address any of these concerns.

There are many types of databases and MongoDB remains one of the top choices for document-stores. "NoSQL" is a meaningless term and is yet another point underscoring how better marketing always wins.

The last theory I heard was that fish developed calcium deposits in order to move up river deltas into fresh water. Calcium is important for muscle function and you would have to bring a stable supply with you to survive.

The fact that mammals still cycle calcium in and out of their bones to manage blood chemistry was as I recall used to support that theory.
It would be helpful if you defined "distribution of minimal depth", described how to interpret those statistics, and why we should care about them. I tried Googling the term to find out more, but to no avail. As a result, I couldn't follow the rest of the vignette.

I get that these kind of posts can seem interesting to the software engineers that are predominant on HN, but these kind of articles are ultimately "popular science" articles. They only give the illusion of understanding.

I'm tired of people trying to find or make shortcuts to advanced topics. If you want to truly understanding something, put in the work. Shor's actual paper for this is only 25 pages. You need a strong background in advanced linear algebra and quantum theory to understand it. If you don't know quantum theory and linear algebra, you are fundamentally incapable of understanding Shor's algorithm. It's like trying to understand how compound interest works in finance without understanding what multiplication is. There's no point, you shouldn't even try. It's wasted time, and anyone who says otherwise is missing the point.

If you're serious about wanting to understand advanced topics, put in the damn work. Stop trying to find or make shortcuts. Shortcuts only produce a bunch of know-it-all armchair scientists that think they understand something just because they read a blog post about it. People spend their entire lives studying these topics. Are you so presumptuous?

Don't get me wrong, analogies and novel perspectives can be invaluable learning tools. But they can never be a substitute for the fundamentals, only supplement them.

Anyway, I apologize for the rant. The author is clearly interested in QI and has put a lot of effort into his articles. That is to be applauded. But I caution anyone reading this, or any other article on QI, to be aware of the fact that he or she is reading a shortcut and should not believe that he or she has actually understood Shor's algorithm.
Reminder: they shipped with the defaults which basically would throw the data over the wall and never acknowledge it back to the user (because speed and such). Interestingly enough it still called itself a database, and that right there is the power of marketing.
The Crowd Has Spoken
It's way too easy to binge on carbs and it's really really hard to eat too much fat. I've guzzled 6 packs of beer and eaten entire pizzas in a sitting more times than I care to admit. (Also because I lost count after the first dozen times or so).

Now that I'm on a low-carb high-fat diet, I find myself eating until I'm full, and at that point I simply have too much fat and protein in my stomach for my body to even want any more food, so I stop. Then I wake up the next morning to find yet another half-pound of body fat has mysteriously vanished and my clothes fit better.
Tango has technically been a failure in terms of the specific AR hardware. No adoption and no real software support.

Apple's purchase of MetaIO and its focus on just SLAM is really the right way to go. Maybe improve it a bit via specialized hardware when available (progressive enhancement in a way), but at least start with SLAM.

Google didn't have to be behind on AR at this point in time if they had ditched the focus on Tango hardware and instead focused on SLAM.

But that is water under the bridge, Google is now on the right track after being forced to do so by Apple.

Because people think fat in nutrition = fat in the body. And looking at the amount of low-fat products on the shelves, people just don't care enough to work out the difference themselves.
I bet it's also illegal to "tamper" with your own car in such a way as to stop this from happening, but clearly it's been decided the law is not important here.
Yes, everything you type is sent to their servers AFAIK.
It's worth remembering how Facebook got to the userbase that it currently has -- they didn't start out targeting "everyone on the planet", which is an almost impossibly hard challenge because of the network effects you note.

Instead, they started off providing closed social networks for existing groups of users -- colleges, starting with a small number of elite colleges and slowly broadening out from there -- until eventually it became a public social network and the de facto standard at least within the US.

The networks that have attempted from the start to get everyone to sign up have mostly failed. E.g. Google Plus, which had some feature advantages over FB at the time, started out much too ambitiously in my opinion and suffered from a "Potemkin village" issue where (unless you had a circle of friends who all joined it) it felt empty, and I suspect many users never used it more than a few times.

The only recent network I've seen to go the Facebook route is Nextdoor, which at least in my anecdotal experience seems to be becoming a thing. By providing a semi-closed social network based on physical proximity (neighborhoods), it provides immediate value to a new user. I'm not sure of the details of their rollout strategy, but at least at one point they insisted on mailing you a physical postcard in order to verify your address (much like FB's original validation on specific .edu email domains).

Anyway, if anyone out there is thinking of challenging Facebook on the social-network front, I would put some significant thought into the rollout strategy and aim not to compete with Facebook circa 2017, but instead to compete with Facebook circa 2004. As other networks have opened themselves up, there's a constant vacuum at the lower, more-specific, more-exclusive, closed end of the spectrum which provides a lower barrier to entry.
React-material-ui with a pure Java stack
While I too wish it was able to be disabled easily, I'm surprised the parent poster is getting down voted. Having worked for hardware companies, and chip companies in particular, I can very easily see the benign answer being that this isn't even on their radar as something to do. That they are providing the ME features because Sales Guys say that some big enterprise customers want them, and once it was designed in, there wasn't a convincing proposal to make it an optional / opt-in feature, because there simply isn't someone on the engineering team who is voicing the concerns of the "home PC user who cares about this-kind-of-thing."

And even if there is, the "non-evil" reason for keeping this as is might be that "enterprise customer doesn't want something that is easily disabled, and we can't justify cost of a separate design / fab run for a small minority of customers", vs. "Haha, now we have a backdoor into EVERYTHING!"

(Hell, even the proposals about disable via hardware switch, or having the ME on a separate component probably boil down to money. To an outsider, hardware companies are funny beasts in that they really start caring about things like counting pennies and minimizing BOM cost as much as possible. I've been in worried meetings where we were literally counting and debating pennies, and wondering how I got there, but it makes sense at a company level since those pennies add up when you are building thousands or millions of something! This may have boiled down to "motherboard manufacturer doesn't want to have to put another mechanical part on the board, and they are looking to buy a shitload of our parts, let's keep them happy")

Please note: I'm not saying, or even advocating, that this is a good thing, or results in ideal outcomes when I say "benign". I'm just using it in the sense that this likely wasn't a malicious decision, but probably one motivated by money at some point, by people who didn't necessarily see the harm in it.

Perfectionism has no place in a startup
I have to agree with this line from the report you linked: "However, it is a reasonable assumption
that adversaries will eventually devise targeting techniques, especially in the littoral areas adjacent to their homelands"

If China wanted to, they could develop the capability to track aircraft carriers -- especially within striking distance of the mainland.

But there's a much larger implicit assumption threaded throughout the report -- the assumption that our aircraft carriers will be cruising at full speed and on high alert in prepared and competent battle groups at time of attack. The assumptions of a maximally defensive posture and extreme competence are present in virtually every argument advanced by the report.

The most significant US naval defeat -- in which damn near the entire Pacific fleet was wiped out -- suggests that a full threat assessment should relax most or all of those assumptions.

Particularly given the article under discussion.
I'd go farther: I'm unsure that communication technologies past approximately the telegraph have actually improved quality of life more than they've harmed it. At least in developed countries (simply don't know enough about life in un-/under-developed countries to have an opinion).

Looking at the commits for GitLab CE, I can't really find a single recent contribution by someone not employed by GitLab. So I doubt it "gets fixed faster" than the enterprise version.
Censorship is fine. Use it as a tool to maintain social order.

Don't be the guy that read 1984 and thinks all censorship is bad, and that the world is going to collapse because someone banned a neo-nazi forum. You don't have enough information to make that far-reaching slippery-slope conclusion, mostly because of the millions of other factors that you didn't consider in your model.

We need to encourage companies that engage in this behavior that censor violent people.

There will be a few different abstractions.

Google has already abstracted it to WebAR on both iOS (via ARKit) and Andriod (via ARCore) here:

And of course Unity and Unreal Engine will also act as abstraction engines for native as they tend to do.
What does a post-privacy world look like?
Data-gathering companies can and do co-operate, or someone wanting to learn something can just buy the data from several of them - price per bit of data should be the same. So breaking them up isn't really a solution to this problem.

As for why monopolies aren't getting broken up, I'd say a combination of increased corporate control of government, and global trade necessitating ever larger companies to compete, because tariffs are 'evil'.
I thought ARKit was derived from metaio's technology? https://techcrunch.com/2015/05/28/apple-metaio/

LOL no. 99% of it comes from actual, working DBAs and others with production responsibilities.
> "Immobilizers are most often seen in cases of sub-prime borrowers with questionable credit," he said. "The devices are very effective at keeping people on time with their payments."

John Oliver did a whole segment on these scummy dealerships, unloading shitty cars at massive markups deliberately (and not even hiding that they are) targeting borrowers who will probably default, so they can repo the car and resell it to some other poor person.

None of this is illegal (except in this case obviously) but it still feels like something that should be illegal, amazes me we're so poor at going after what's obviously a predatory business practice.
My advice is to go to meetup groups, conferences, and workshops where you can interact with others face-to-face. I just got back from React Rally in Salt Lake City, and I often attend Sacramento and SF Bay Area JS meetup groups. Find a group in your area, and you'll quickly pick up on current trends and recommendations.
He has a point though. Right now if you have an android smartphone, use gmail and google search you're telling google basically everything you do, where you are, what you have an interest in and the people you know.

Each of these services in isolation can know a great deal about you but being able to correlate the data makes it so much worse.

That's why I try to avoid putting all of my eggs in the same basket, I have an android phone but I use duckduckgo for search, my own server for email and firefox for browsing the web. If Mozilla, my server host or ddg decides to betray me (or gets hacked) at least they only have access to a slice of my life.

I wrote an article about how Microsoft thinks about mixed reality in our developer documentation: https://developer.microsoft.com/en-us/windows/mixed-reality/.... The term comes from a paper published in 1994 by Paul Milgram and Fumio Kishino. Our usage of the term mixed reality derives from the concepts they introduce their, in particular the virtuality continuum.

It is fair to say that the headsets being introduced this holiday target VR experiences. That said, we are building a platform that covers the entire spectrum of devices (from HoloLens to all the new headsets coming this holiday). The platform is consistent between all of the devices. In fact, we made very few additions to the API set from the original APIs introduced with HoloLens to support these new devices. Since the platform supports the broad spectrum of devices, and it's a single API set for all of them, it only makes sense to refer to this category as mixed reality.
Roll up the shades.
We simply need laws against data brokerage.

No, in that there is not a master clock, shutter, or anything like that that separates the visual input into discrete frames.

Yes, in that phototransduction is a sluggish chemical process. The impulse-response functions of photoreceptors are pretty well-known (e.g, Figure 1 here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1189952/?page=5). The tiny square wave at the bottom is the visual stimulation; the other traces are the responses of individual photoreceptors.

Figure 4 of the paper (p. 689) shows the response to a pair of flashes. In the bottom-most trace, you can see that the photoreceptor "misses" the second visual stimulus because the responses evoked by the first and second stimuli overlap in time and interfere.

I'd say that the visual system does get a continuous stream of inputs, but its output is low-pass filtered (and clipped, rectified, etc) so that faster inputs are not always reflected in its output.
It would be cool if you could

Could you consider a dedicated server instead of a VPS? Depending on how great your desire for larger storage is, one of Online.net [1], OVH [2] or Hetzner.de's serverbörse [3] might be a better fit.

It does, yes, but the CDD standards are much worse than a 2015/2016 iPhone, or a recent Google Nexus phone.

If "population density" was really the dominant reason, then New Jersey would have a public transportation system far better than most countries in Europe.
Yes I agree that watchers/readers are not always focused on the main question. In any moment you feel drawn in to a story you might be drawn along by a secondary or tertiary question. Storytellers weave them together into a tapestry of compelling viewing/reading. Think of a single joke you might hear in a show, 'Why did the chicken cross the road?', we immediately think, 'How is he going to try to make this old joke funny now?'. Once a story loses its questions for you, you lose interest in the story.

That the pH is lower has apparently been known for a while. What's not been clear is the cause of the lower pH and whether the low pH is causing the disorders or if it's just a side effect of an underlying cause or of the medications. This still isn't clear. It could even be a combination of factors, with low pH caused by lactate production stimulating the disorder which increases lactate production... etc.
Consider lobbying your government officials to improve regulations concerning this. Maybe get together with other people in your city who care about this particular issue.
