As I understand (or maybe I should say "in my opinion") the magic of the gaussian distribution lies in the two assumptions you make. You have a rotational invariant answer (X and Y are related) but you are assuming the distribution in X and Y are independent. And these are valid things to assume.

The gaussian distribution is not a particularly good representation of most real problems in the sense that the probability for large errors decreases far too rapidly. Maybe there are ideal cases you can say are gaussian, but in any real problem there are some kind of outliers. We go in to a calculation assuming we have gaussian noise but really we don't. And, we have to add additional logic to handle these "outlier" cases.

The thing that is magic is that the gaussian distribution factorizes. If we are evolving the state of a system after taking a measurement, as long as the system had gaussian errors and the measurement has a gaussian error, the system after the measurement will still be gaussian. We can paramterize our errors with two numbers, the center and the spread.

If we didn't have this factorization, the distribution would change shape after the measurement. We would have to keep a ton more information, the amount of which grows geometrically with the number of variables we have. It is just intractable.

So as I see it at least, we use this distribution because we can, more so than because it is the correct one. (But, of course, it also still does work pretty well!)
> I am not an expert on this subject matter but I suspect much of the required structure for younger kids is only a necessity due to constant restrictions and monitoring that's been put in place by modern society. In other words, we are not giving enough space to develop on their own terms and explore their surroundings.

It's mentioned by Piaget that kids are inherently ego-centric at that level, and likely won't share. It think it's a generally relative thing for them to be very self-centered at that age.
Make sure you spend enough time outdoor too, especially during sunny hours. I recommend hiking and nordic walking. Once started, I forgot SAD.

Scandinavians say "there's no bad weather, just bad clothing".

Invest in some good termoactive clothing, avoid cotton underwear. Always take some warm drinks and extra cloth for remote trips. Enjoy the season!
It does. A few years ago, I decided to chase down what Windows Update does, so I ran regmon to see what configuration keys it builds in for tracing. Turns out it has a LOT of trace parameters in Windows 7 (and I assume for Windows 10 as well). It basically has tracing for each component.[1] But one component in particular takes a long time - and that component seems to be the one that determines the package dependencies.

Honestly, if Microsoft would fix this one thing, I suspect they could speed up their update process by a factor of 2 or 3, possibly higher.

As an aside, the Windows Update datastore and the Windows AD datastore must be seriously some of the very last things to use the ESENT. Dunno if Exchange still uses it. Awful way of doing things though.

Windows Update is overly complicated and utterly unweildy. My perspective is that it was rather bolted together in the years when Microsoft decided to make the filesystem a database. They now have an inelegant mess that they cannot easily get rid of. I would hate to be someone who had to work on Windows Update code!

Damn, that was harsh on Google Keep. It was basically written by and operated by a single person in his spare time.
One of the challenges I’ve found with OOP is that’s really easy (encouraged!) to use a lot of “anti-functional” patterns.

A functional style is not the only way to write programs, but it’s often much easier to reason about behavior when you’re not chasing side effects.

And OO implementations often have a LOT of side effects.
I grew up in a suburb of Detroit, and came of age in the early 80s. Every time a "business cycle" came along, the leaders of Michigan swore that Detroit needed to diversify into something other than cars. Then, when things picked up, all was forgiven and we started making those cars again. Rinse and repeat.

"Detroit" meant all of the Midwest, since every town had a plant, small or large, doing something for the auto industry.

I hope it sticks, this time.
PFS is not magic, it depends on exactly the same type of trapdoor algorithm as other asymmetric cryptography but using randomly chosen keys which are then forgotten. Forgetting the keys + Breaking them being too hard = Forward Secrecy. If someone finds out the key later, they can decrypt the messages, just as if they'd been told it at the time.

A Quantum Computer that breaks say, 2048-bit RSA also breaks the PFS-enabled Diffie-Hellman style key exchanges, it's almost exactly the same trick, a variant of the Discrete Logarithm Problem.
Me too, I've experienced that before, and I see signs of it online today by post-college aged people. I'm just trying to sort out the difference between being too uptight and pointing out what their jokes are really implying. It's like "Okay, you're making fun of me for worrying about something you think is silly. That's fine. But what exactly are you saying in response? You _don't care at all_? Are you telling me that you're a sociopath?" It's the particular formulation of _some_ of these jabs that get me.

Even if they say something like "the cow was stupid anyway om nom nom" _that's different_ because at least they're not necessarily in favor of torturing the thing, and they give a reason why killing it humanely is different from killing a human humanely.
Yep, unrolled AES instructions are the way to go if you need to hash gigs of stuff and you're on a CPU that supports them.

I was a founder and operator of the Los Angeles free co-working space DropLabs. We lasted for 3 years before closing out of lack of interest. We never intended anything other than a free place for geeks to collect and work. We had events in the evenings, which were fairly popular. Having multiple partners with graduate business degrees, we chose not to incorporate, we just rented a space and called it "Droplabs" (why invite the taxman?)

However, our location was near downtown, and the 20-something geeks were both afraid of downtown and would rather pay $40-$60+ per day to have a chair in a WeWork space in Hollywood or Santa Monica. It did not make sense, so I tried spending a week at each of the more popular co-working spaces, and learned they were not occupied by geeks or "real" startup people, but wealthy 20-somethings playing a startup game, dating one another, and with zero serious intent other than wasting their parent's money.

I learned to be a success as a co-working space, one needed to create a "dating safe play pit" for white wealthy 20-somethings. I have zero interest in that.
I am looking forward to the day we have high quality artificial meat, but how many jobs will that cost? Most farms (even not meat farms will produce feed for other animals), a big part of shipping and mostly everybody who works in meat packaging.

With automatic cars and factory meat, that will do a huge number on non coastal areas of the US. We need to take that into account for the planning process as well.
Exactly, many of the new trendy languages have a corporation behind that can with money and by association get the language known.
The cost of the second kernel trip (on the first page fault) is often mitigated by speculative read-ahead, or the fact that a given page is often in the UBC already. And file-backed memory doesn't contribute to dirty memory. And mmap() makes it easy to use read-only memory, which catches memory corruption bugs. Plus it's easier to use huge pages, which reduces TLB pressure.

I have like 4 windows PCs, three laptops and a 5-6 year old desktop. Never an issue, ever.
The only sensible way to update Windows is in a virtual machine hosted by another operating system, so the block caches don't get dropped by the reboots. When operated in this manner you an actually blow through a huge backlog of updates in no time.
Thanks, ~170W is better but still far off from 95W.
Unfortunately, no.

That is the case with GCCs __builtin functions. With a few exceptions, intrinsics are basically macros for inline asm that the compiler can reason about.

If on x86-64 you use a _mm256* intrinsic and compile without AVX support you just get a compile error, not a pair of equivalent SSE instructions.
I wonder why they choose Obama and Hillary as examples for being deepfaked. Aren't they basically retired now?
Yeah, I would love that. Don't think that will happen any time soon unless legally obliged to.
xoa, I think you've gotten lost in your own argumentation: besides saying that paid upgrades were not a scam, you were also trying to convince newtacamp that charging money for the OmniFocus v2 to v3 upgrade is perfectly reasonable, if you remember...

You claimed that "developing major new versions costs money" and that "it's normal that all minor updates are free".

So far, so good, but the fact whether v3 is a major new version in anything but name seems to be critical to the soundness of your argument. I have v2 and the v3 trial on my device, and unless changing the icons and moving or adding a few buttons counts nowadays as a "major new UI rework" this app did not in fact go through a major UI rework. Neither does it have any groundbreaking new features, rather it's playing catch-up to Things v3 from more than one year ago.

OF v3 is not worth the 20-30 EUR IMO. I do have Things 3. These guys did do a major UI upgrade when they launched it and still managed to charge one third of the OmniFocus upgrade price for the new app.

AppStore upgrade pricing is not a scam, but it's still complicated to get right and can alienate users. I've given two reasons why in this thread: family sharing for IAPs and features / upgrade price ratio.
Socialized Medicine and Education are often discussed in this context. However, if we look at Europe where student debt is minimal, and medicine is provided by the state fertility rates are even lower.
Exactly this; frankly, I think it's amazing that Haxe is as relatively well known as it is given it's humble origins at a once obscure* French game development studio.

It's not a surprise at all that the likes of Microsoft and Google and Mozilla are able to promote and push new languages to significant widespread adoption.

*Not so obscure anymore; Motion-Twin is well known for the hit game Dead Cells, and their former employee, Nicolas Cannasse, who is credited with inventing Haxe, went on to found his own studio with its own successful games (Northgard especially)

Although social media might be the wrong thing to take aim at, I would argue that rising expectations for standard of living definitely have helped to reduce the amount of (relatively, but not ridiculously, wealthy) couples who wish to have kids. Narcissism tends to drive the expected standard of living, whether exploited through advertisements or broadcast through social media itself.
Heavens, I thought the fire was an allegory or a worst case scenario. Looking at the artsy enterior I feel an existential dread thinking about being trapped in that place with flames around.
This is probably part of the reason that the payment popup became much more obtrusive (and incidentally nicer) in iOS 11. It doesn't look like a normal alert anymore.
Homelessness is an incredibly simple problem with an incredibly simple solution: build more housing. Since this is not a step in that direction, it does not seem like a "step forward" to me. If anything, all these "occupods" do is widen the social divide between homeless and housed people..... While poisoning the homeless with chemicals from the wood pallets. LMAO at this misguided attempt to do good that actually does harm.
I didn't find a reply yet, but I did find a screed demanding "Bring Back Meldrim Thomson's New Hampshire".

http://valleypatriot.com/bring-back-meldrim-thomsons-new-ham...

He was an interesting character, according to his Wikipedia page.

"During his governorship, and thereafter, Thomson was criticized for a number of controversial actions:

in 1976 and 1977 he ordered the flag at the statehouse to flown at half-staff on Good Friday to "memorialise the death of Christ on the Cross." [1]

having an aide examine his political opponents' tax records, a move later invalidated by the New Hampshire Supreme Court

suggesting nuclear weapons for the state National Guard.[10]

during the 1977 anti-nuclear demonstrations in Seabrook, he dressed in military fatigues and was brought in by helicopter to order in person the arrest of 1,400 protesters.[11]

personally arresting speeders from his official car.[12]

visiting South Africa in 1978 and then praising the government and its apartheid policy.[13]

threatening to veto all funding for the University of New Hampshire in 1974 after the Gay Students Organization held a dance and performed a play on campus.[14]

sending out a press release in 1977 saying that he wanted journalists to keep the "Christ" in Christmas and not call it Xmas, which, he asserted, was a pagan spelling of Christmas, despite being a representation by the Greek letter chi.[15]

petitioning unsuccessfully, in 1990, that candidate Dick Swett (for New Hampshire's 2nd congressional district) be listed on the ballot as Lantos-Swett, the name he had used in the telephone book, voter registration, buying real estate, and business.[16]"
Saying there's a lot of work to do and it's unclear whether there will be a practical solution in our lifetimes is very different from calling it a hoax. Comment even makes an absurd appeal to authority. It's intellectually dishonest and doesn't belong here

While this may be true, it's not that much of an exaggeration to say that capitalism is a Ponzi scheme. At the very least our current economic system is dependent on continuous growth, including population growth, and when that ends there will be a world of hurt.
This is such a common comment on HN that it makes me believe that a small portion of the population doesn't realize that "hey, that word can mean multiple things" is a thought everyone has all the time without considering it particularly noteworthy.

Of course, it's really just an opportunity for some weak posturing like "heh, I thought you meant floppy as in the floppy disk, something us grey beards had back in our day ;)."

I think i see the confusion:

1% vacancy

5% unoccupied but not open to rent

So of the houses that are unoccupied, only 20% are vacant?

(I actually read it as 1/6th but the point is where the confusion may have come from)

Mac OS means buying unaffordable or underpowered hardware. And being ok with living within the constraints allowed by Apple (on the hardware side).

Linux is not a consumer option. Ubuntu, for all its flaws, was the first distro that could actually be considered consumer grade, and that’s why pretty much any mainstream PC maker offering a Linux option offered Ubuntu. But as you can tell by just glancing at the comments on the release for Ubuntu 18.10, even they have seemingly abandoned the desktop market in favor of servers and IOT, etc. And that’s before you get to Linux’s Applications problem.

Windows is a fairly solid OS with a few remaining warts which MS stubbornly refuses to address. One of the issues was the years they spent trying to convert it into a Mobile first OS. That was such a waste of resources.
Oh, I missed this response (still a little overwhelmed). I'm so glad I checked again because there is some precious wisdom in there. Thank you for taking the time to write it down. And it indeed seems like I was misusing mmap...well, next time I'll know better!
Apps don't have access to the actual fingerprint data, though. Presumably they were just using it as a login guard?
I don't really disagree with any of that. Even if you don't think that vehicle sales will fall off a cliff and even if you have confidence that the big automakers and their suppliers can get to self-driving and electric by the time there's a sizable market for them, it's hard to see a scenario where the market for consumer vehicles increases or even stays flat.

I actually dumped my auto stocks fairly recently. It's a lot easier to imagine downsides than upsides for the industry as a whole, much less individual companies that, as you say, don't have a great track record in recent decades.
So I decided to go on dictionary.com. Here's what I see on the front page:

-We asked "What is the state of the USA in five words? The responses are not what we imagined."

-Can you translate these famous quotes from emoji?

- How is pansexuality different from bisexuality?

- Epic Fail. (seriously, the article is titled this.)

- When a cat is so cute you want to bite its face? (sic) There's a word for that!

Those are some of the articles on the front page. Clickbait, on a dictionary. Then you start to wonder why you are trusting it when it needs to monetize with clickbait.
Moreso, it's a reminder that "training an ml model" isn't a controlled experiment. It's a process for constructing a tool.

You aren't hiding anything, training wasn't (and isn't ever really) rigorous. You're more than likely discovering issues in your data set. It's like polling. You don't cover up politically inconvenient polls, but there's often a level of post processing you need to do to account for biases in your sample.

Same with ml, except often times the first data set, or three, are useless because no one has ever analyzed them before and doesn't know how to post process correctly.
More importantly, how many _American_ cars will be put on the road by Uber and Lyft? I think I've taken my share of Uber rides and I can't recall any that were in a domestic car. The drivers are obviously very sensitive to the economics and they are all driving Toyotas.
I didn’t mean that they’re biased, just that being “black” correlates with “being poor”, which is not biased in any way but might still appear so based on superficial view(well, the data/AI isn’t biased, though the society might be but that’s not the bank’s problem...)

Edit: biased not busy.
You’re assuming that the person trying to expropriate wealth cares about being able to spend it themselves, rather than e.g. their family who already lives in Canada being able to spend it while they sit in jail.

Counter-example: Dart.

If corporate support is a definite factor, Dart would have taken off way earlier than now. A bigger factor in TypeScript's success would be the ability to gradually migrate the projects as it's a superset of JavaScript. How do you start migrating? Flip the file extensions from .js to .ts with loose compiler options, then gradually add typing as the options are tightened. It's factors like these that drive spread of language, not "huge corporation with infinite budget and a large full time team of contributors and evangelists." Dart had no short of those and still not much accepted.

FireEye does this well in their sales process. They make the organization invest time. I.e. You sign a contract to allow the trial tier only if it is installed on a number of systems in a given period of time, if that is not met, there is a consultancy fee. Once you invest time into the system, the organization is compelled to go forward with it.

I liked how the article presented a diverse set of political opinons; Left, Right, and Crazytown.

"Economist Lyman Stone has blamed the United States’ less-than-generous parental leave and pay policies. Human Life International, a missionary group, blames “pro-abortion population control groups like Planned Parenthood.” Tucker Carlson claims it has to do with immigration, arguing that immigrants drive wages down, which hurts the attractiveness of men as potential spouses — “thus reducing fertility.”"
That’s my point. The child rapist on parole scenario is a straw man. They don’t need breakable encryption to address that problem. Parole requires the parolee to sign a contract. Put a no smartphones clause in there and they’re done. Then they can rearrest on that basis alone if he has a smartphone, and let him serve the rest of his original sentence.
I don't even use Windows, yet I still notice them when being at a game jam or a similar event. There's always somebody who complains about his Windows that started updating, with the best case being a guy waiting for his turn to connect his laptop and give a presentation, only to notice that it started updating meanwhile :D

First world countries' with shrinking populations aren't falling apart. Sure places like Japan, Italy, and Spain have economic troubles associated with a growing retirement population, and shrinking workforce. But they're still pretty good places to live in.

While global growth would decline, I'm dubious of the claim that per-capita wealth would go down. With the same pool of resources spread across fewer people, the opposite seems likely. The labor force would reduce in size, too, so manufactured goods and services may not see their prices go down. But things that are zero-sum like natural resources, real-estate, etc. should drop in cost as fewer people are competing for them.
