> Drug users on the other hand will tell you that it not as bad as alcohol/tobacco/coffee/... that concerns are unfounded, that police is the only risk, etc...

Sure, some ("plenty", in absolute numbers) will tell you this, but I don't recall being in many forums where that attitude doesn't get significant pushback (as opposed to the anti-drug community). The modern "pro drug" community has a fairly significant culture of safety within it, unlike back in the sixties.

> The truth is almost impossible to find.

There is plentiful anecdotal evidence online. Any clinical evidence, if they ever get around to doing it in any significant volumes, will be utterly miniscule (and I highly doubt more trustworthy, considering what you're working with, and the size of the tests that will be done) to the massive volume of trip reports and Q&A available online, much from people who know very well what they're talking about, not unlike enthusiasts in any domain.

> Now from what I gathered about LSD (and psychedelics in general): these are very random.

Depends on one's definition of random.

> If you take a reasonable dose, you are most likely going to have a nice, fun trip and nothing more.

Effects vary by dose of course, but I've seen little anecdotal evidence that suggest high doses have a different outcome, and plenty that suggests the opposite.

I believe this to be true, but don't forget the fallacy noted above.

That said, these things are not toys - extreme caution is warranted.
I find the time constraint to be a strength (used to do these in college - won some prizes, sometimes didn’t finish in time). It’s a beautiful thing to work on an ambitious thing against a clock, knowing that if you fail you can walk away. The ticking clock forces you to put your ego and perfectionism aside and ask questions of the interesting people around you.
I'm convinced that prototype object systems represent a poor set of requirements.

Those requirements are chosen because they lead to ease of implementation: prototype objects are the quickest and dirtiest way to enhance an interpreter such that programs can be written in it that are discernibly OOP-ish.

They don't represent a set of requirements that amount to a good OOP system.

Javascript code doesn't just stop executing for no reason, if the callback needs to stop executing, it should reject the promise or throw an error. Or resolve with an error value. That's like saying "in sync programming, if you don't check for error conditions, your code continues humming along happily just the same".

If there is an error when reading a file or accessing a database, unless the file or database API is horrendously designed, it will reject the promise or throw.

I mean they'll have one App and UI toolkit (probably based off ios) which handles both desktop and ios, simplifying development, making cross platform apps easier, and dramatically cutting support costs for Apple.

At the moment the base OS is the same but the huge SDK used to create apps has two parallel tracks without a huge amount of overlap (though they are increasing the overlap, and encouraging things like porting from ios to Mac OS). Each SDK takes a lot of resources to maintain and support.
You can get 'spirit' through art in the form of books, pictures and music. It's a lot more potent and designed for the purpose rather than just having that purpose tacked on to sell a product.

RE: Convolution

I think this was a pretty neat explanation:

https://sites.google.com/site/butwhymath/m/convolution

The problem with convolutions, like many things in science, is that how you learn it, depends on what you're studying. Same theory, but with N different explanations, which can cause confusion if some of them are very different and tough to connect (i.e learning convolutions in a physics class vs leaning one in a statistics class)
Oddly enough the Ukraine metaphor is pretty apt when comparing English to Russian, considering that Eastern Slavic languages came out of Kyiv / Kievan Rus civilization, just as American English originated in England.
Consider the vectors of the four forces (thrust, drag, lift, weight). The thrust only needs to equal the drag at a given airspeed, not the weight of the vehicle. (Unless it's climbing vertically.) The weight is countered by the lift generated by the wings, which, given the efficiency of airfoils, is very more or less why it all works: they produce a positive lift-to-drag ratio.

Put another way, weight pulls it down, thrust moves it forward, the resultant lift keeps it up, and drag limits its speed. Only rocketeers and fighter/aerobatic pilots need to really worry about the thrust to weight ratio as a constraining factor, because the vertical flight regime matters to them. From your average bugsmasher to your commercial airliner, it's not a factor (to the disappointment of pilots everywhere).

Consider that a Cessna 172 has a glide ratio of about 9:1, so it can go 9 units forward for every 9 of altitude it gives up. If that's hard to intuitively grasp, consider that it's traveling through a fluid. Surfing, even. The interaction with that fluid is why it works.

That any more satisfying?

Twitter is a platform for out-of-context, extremely condensed texts. Both together is very difficult to handle. And many people just use Twitter when they feel they have a stupid idea, kind of a platform competing for stupid jokes.

Also, if you hear some comment like this in real life, do you set on a quest to destroy that person's life? No, you got your own things to deal with.

In my perception, the US are very hype-driven. Someone from somewhere said something. Everywhere: nothing. US: Media coverage. We have a president that constantly tweets things way worse. Why worse? Because these words matter! The author's "most damaging tweet ever" should not have mattered, to nobody. The most severe consequence should have been the lack of likes.

Domestic use of US soldiers, even with a state request, is not a simple matter. Trump wanted to deploy troops along boarder --> no go. Federal troops cannot be used to implement domestic policy. New York probably couldn't get troops if it asked.

Canadian troops, if asked by any level of government, can deploy domestically and do so regularly. That's the advantage of a single sovereign authority (the crown). Everyone is literally on the same team.

The US fed exercises its health power indirectly, through spending. It can demand that certain hospitals, those that receive federal funds, act in certain ways. But it cannot dictate treatment regimes. (This fed-state split on health has been heavily influenced/reinforced by the abortion debate.)

It doesn't, it's just a lot denser. A star has a lot of inner pressure from the ongoing fusions inside of it. When these stop or reduce, the star collapses from its own gravity, as soon as its radius is smaller than the event horizon (i.e. the radius at which the escape velocity exceeds the speed of light) you have a black hole.
DP3T is exploring various options for this, smallest daily proposal currently being 5MB, bigger picture download around 100MB. Worst case mobile providers could always be compelled to exempt this from data usage. That aspect seems pretty solved.
Yes, as they eventually did with the OS X transition, the 64bit transition etc

They'll support older apps for a long time though, it just won't be the preferred sdk and will gradually be phased out.

The situation they have right now is madness - two parallel slightly different UI toolkits and SDKs, one of which makes vastly more money.
This would be so cool.
I would still limit it somehow, tho, like at 5000 characters, to force everyone to brevity in line with twitter micromessaging branding.
Honestly, also think of the amount of subtle, non invasive and highly targeted advertising space they’d just spawn out of thin air...
World Models (the long version)
I don't know if "screw everyone else" is fair. It's the idea that living freely is a sacred value; that we won't and shouldn't take the path of the fewest deaths, if that path leads to a society we don't want to live in.

That's not to defend people who actually have the virus breaking quarantine. Limited quarantines have always been compatible with freedom, that's just dumb selfishness. But if the proposal is that the 30k new infectees a day* and all their close contacts should be forced out of their homes into quarantine camps, yeah, that's not going to work here.

* I know the real number is likely much higher than this.

I don't remember who but someone (Naval?) had this quote that generations 100 years from now will think of us as utterly barbaric for eating animals. When I look around how we treat animals as if they were just sacs of meat, its amazingly heart wrenching. In Alaska I saw a casual 4th of July competitions where you throw dead fish and other person catches it. Sometime fish fall apart and all its guts spread out during these games while audience literally laugh at that scene. I wonder how people get so heartlessly cruel that not only they are killing animals for entertainment but also enjoy when their bodies fall apart? What is their internal justification system? A devout Christian explained to me that its their God given right to be superior to animals and God has instructed them to consume these animals. In a Chinese restaurant I had hard time explaining someone that fish is not really a plant. It seems minds can be programmed to shield away from any cruelty. Perhaps that's how people working in Nazi camps justified cruelty towards Jews: they aren't really living beings like rest of us, they are something else quite lower so no need to take all these to heart.
What teachers tell you in school is that as you get close to a uniform sphere the gravitational force increases with the square of the distance to the center of such sphere.

What they don't tell is that once inside the sphere the force decreases linearly, because the planetary mass ahead of you is partially balanced by the mass behind you.

With this you can see that the gravitational pull of a planet/start/spheroid is largest at its surface. So, if something happens to make a start shrink by some factor, the gravity pull at its surface is increased by the square of this factor, even if the mass of the star remains the same.

Actually I believe starts eject a lot of mass when they become black holes, and this is just a Newtonian argument for a phenomenon intrinsically relativistic, but I hope you get the gist of it.
The problem here is that this conversation is made complicated by the fact that plain objects in JavaScript are not what is really being talked about when people say the term OOP. So to clarify, stateful classes would be what I am talking about when I use that term. The foundation of OOP is based on tying state with functions in what are deemed "Objects". This implicitly makes all methods in an Object that depend on or modify an Object's internal state impure functions. And the purpose of most Objects methods are for the purposes of doing those things. Basically if you use stateful classes that encapsulate state and modify their own internal state with functions you are not doing functional programming. These two paradigms are in fact at odds and not compatible.
What is it about a wing that can take 100 pounds of "thrust" (and I may not know exactly what "thrust" is), and use it to keep a 1,000 pound aircraft in the air?

I want to go up. I want to use the thrust I have available to achieve that. Would not the most efficient use of the thrust available be the direct and naive approach, of pointing the engine straight up/down? Nope.

Instead, we point the engine horizontally; literally orthogonal to our desired goal. Then we use these "wing" things - they're not complicated, they're just rigid bodies with a shape, which honestly isn't even that unusual of a shape. Now we're not only able to go up (we finally achieve our goal), but we get to go fast in some horizontal direction as well.

I haven't found an explanation for this that feels satisfying to me.
There's been a long, long tradition of software verification at Microsoft; look for SLAM (the original research backing the Static Driver Verifier), Yogi (SDV backend V2), Slayer (generic memory safety) and Terminator (termination of system code). All of the research is out in the open, often with reference implementations.

The problem with all of these things (as with FramaC) is that they only work if you restrict the fragment of programs that you're looking at. Kernel modules work out surprisingly well, because they are not allowed to do a whole lot by convention.

I think this is in reference to the past perfect tense specifically. So "I have gotten sick" vs "I have got sick". I don't know if the latter is actually used in British English, but it's my understanding that the former would never be used since it's grammatically incorrect in that dialect.
Well I’ve seen worse, but then on Twitter there are those who are extremely politically correct and just see jokes like this as an ‘attack’ or somewhat ‘offensive’ and there are those who see this as: Meh, another silly tweet, who cares.

This probably serves as the blueprint example for SJWs and the like on how to cancel and arrest someone on suspicion of wrong-think or jokes like this which I can imagine that it must be really exhausting and boring for them to do.
Well it also covers all of the sub-systems on the aircraft as well, from countermeasures to communications down to how to evacuate the aircraft toilet waste.

The information in that manual is probably spread over the domain of 100's of people all performing different roles. I don't think their is any expectation that one single human would read the entirety.

Kinda like your car manual or university textbook. I've never read mine from cover to cover, but it is a useful reference sometimes. Particularly in the case of Air Force One where I doubt an internet search covers most troubleshooting requirements.
Pakistan is a lot of human created issues though. They have the most fertile land in the subcontinent along the indus river. However they have had absolutely no population control measures unlike India and Bangladesh which are almost at replacement level fertility. Throw in a backward society, mismanagement, lack of democracy and you get this.

My point simply is that the hunger is not merely because of shortage of food.
You will be surprised to know what many poor countries would ban this chicken even if USA were to deliver it for free in their country. (To protect their local chicken industry jobs).

India theoretically could import wheat from USA and Sugar from Brazil and save millions of $$$ and billions of liters of water. However India puts import restrictions to "protect jobs". The poverty of many in these countries is not god designed by a a result of "my country first" policies that Trump champions.

1. I trust this government no more than Mr Turnbull was father of the internet in Australia because he was the legal counsel for Ozemail, or many other denial-of-service attacks & census design (IBM) failures they have presided over.

2. What was this App developed in? Is the user interface UX. Is the back-end Xmarin, C++, Java, Objective-C, Swift or what? What API/s &/or Pods were used to achieve encryption and bluetooth handshake?

3. Source code? Really? What do you expect to see. Most usage of APIs and Frameworks explicitly hides the implementation details from the App. These libraries of independently compiled software can be enormous. People are asking for specifics but will be delivered a haystack. Good luck with that.

4. The open source code will be ripped off and repurposed for school / work attendance rolls or dating App hook-ups. Surest way to expose software to malevolent hackers is to give them the source code.

5. Careful what you wish for.
> The entire point is that it doesn't motivate him or change his feelings, those are his to have on his own terms

But they are not on his own terms, as you admitted in your earlier post ("He buys the Nike’s because he wants to live the dream of athletic achievement that he saw in many Nike ads").

He wants Nikes because Nike ads told him he would feel victorious/cool/whatever by buying them. Nothing in the skateboarder's mind intrinsically wants to buy Nike over Adidas. Nike shoes have no meaningful difference in utility or material to give him different "cognitive spirits". The "athletic achievement" in the ads are not connected meaningfully to the shoes; they are intended to manipulate his thinking into buying the shoe or associating it with an abstract value that is not inherent to any single brand of shoe. The reason he wants Nikes is because of the ads; his desire for them is manufactured by the media he consumes.

I suppose I would reply with the question "is being the top rated Google answer for all sorts of questions enough?".

That is, I can't imagine anyone I know having deliberately visited Quora and used it as a networking site. But I can sure imagine most of the non-tech community searching for a random fact and clicking a Quora link. I'd have to wonder what that means for traffic/load. Certainly I'd expect you could cache a substantive portion of page hits.
Far be it from me to defend advertising, but that assumes a zero-sum economy with fixed productivity and fixed wealth. It also assumes a number of other things, including no economies of scale, no innovation to meet increased demand, etc. Consumer goods are in some ways about as inexpensive as they've ever been. Turnover can create a landscape conducive to innovation.

And all that aside, ads for fractional lending, for example, would theoretically generate capital, and not merely move it around.
So the 'glide ratio' is essentially a multiplier from 'thrust' to 'lift'?
The 10 pounds trust is used to overcome the airodynamic friction, when the plane is in high speed. Because the "way" around the wing is longer on one side compared to the other this create a lower pressure on one side, and higher on the other. This pressure both lift and push the plane up. If there was zero friction you would hold the plane up with zero thrust ;)

I build this at school, using the same principle:

Interesting perspective here. It definitely cuts both ways.

The converse is that if you're able to find product market fit in a down market, you'll have a lean and focused operation for the upswing to accelerate. For most companies that will mean a product people really want, and in the surviving case, probably profit and optionality.
Re: Ányos Istvan Jedlik, I've had a uni colleague and former friend of mine who shared a given name with this inventor and whose family name was 95% similar to his, and seeing as we both live and used to study in Romania (where even the ethnic Hungarians' family names don't generally sound like this) I was curious at first what nationality he was, he told me that he's not sure either, part-Hungarian, part-Slovak. Maybe a similar approach could have been used in this inventor's case (i.e. using the "part-" thing)
