Or Myers–Briggs, which is a lot older.

The main useful thing about this sort of thing, including the more modern Tilt 365 for example, is that it can be a useful exercise in helping people understand that the way they think about and approach the world differs from how others do.

Years ago, I remember a book (Tog on Interface) that had a chapter which discussed how Apple engineers tested on MBTI versus the general population. He went to discuss implications for how it was easier for engineers to have mental models for how systems operated than users. Was this a correct explanation based on MBTI? Who knows. But it was a useful reminder in this case that your users may not be like you.

De gustibus non est disputandum, I suppose. Faking crocodile tears over a family member's recent death is well over the psycho line for me, and "but he had to if he wanted to get money!" is not an especially convincing rebuttal.
Old articles are allowed. They should be titled with the year though.
Fair point. I was specifically comparing "regular" stream calculus vs a special "gifted" class (in the elitist, "my parents have more money" sense) ; I see now you were thinking more of "a subsidized opportunity for people in disadvantaged situations to be exposed to higher level mathematics", in which case, I agree with you.

I'm not saying things couldn't work differently, only that the incentives don't align to make that very easy to accomplish. Tesla did it because they had the advantage of looking at the current status quo and saying "Yeah, no thanks, we'll retain control of whole process."

I get what you mean about certain aspects, but I would not describe the process of buying a car in that way.

I don't know what you mean. I don't think I said much about the hassle of buying a car: I agree with you on that. When I say "service is the key" I mean mechanically servicing the car, not customer service.

I also wouldn't contradict you on the test drive idea, but that's almost exactly how dealerships do it already. Unless you really insist on driving the exact car you're buying, they are going to direct you towards the demo car reserved for that purpose.

Repair shops: Yes they can exist outside of dealerships, but manufacturers can't build their own service centers without bankrupting the dealerships, which is how they get sales in the first place. Dealerships do occasionally flip to another manufacturer if the local market for their cars is bad, and they would do that in a heart beat if the manufacturer opened its own independent service center nearby.

I completely agree that better models for all of this could exist, but, as you said, the intertwining factors are a real rats nest. This is why I'm extremely skeptical when someone claims everything will be different in 20 years. Breaking this rats nest requires some type of black swan event. By definition those are mostly unforeseeable, and I don't see anything right now to change things. Carvana and those like it focus on used cars, which have always been much more decoupled from the manufacturer/dealership relationship already.

As a final side note, you can avoid the 4-hour dealership visit pretty easily these days: My wife just needed a new car, and we worked with their online sales person via email, casually going back & forth 2 or 3 times over the course of a discussing options and hammering out the details. Trade-in value was determined by giving them the VIN # and pictures of the car. When we went in to pick up the car, all we had to do was review the details. There was a little bit of wait for the insurance company to put the car on our policy (they can't do that until the transaction is official) and for the finance officer to be available, after which we reviewed the paper work, signed, and were done. The whole process took under an hour.
>It seems to me that most LEDs dim gradually over time.

Of course, esp. the warm white ones (they got more phosphor). For 50k hours, the LEDs are likely to drop to 70ish% of their original brightness, provided they stay below 50C[0] - lumen maintenance. That would depend on the spec. of the LEDs but it should be a ballpark number.

While this is true for a lot of common psychological constructs, the Big Five were not defined according to agreement or consensus. The definitions were driven by the lexical hypothesis whereby the wide variety of personality descriptive adjectives in human language were factor analyzed and found to cluster into 5 distinct factors.

So this isn't tautological in the way that you've described, though it is certainly related to the way human beings describe each other and the way that instantiates in human language.

"Suspend Tab" for not loading inactive tabs is also important. I typically run about 50/50 in my active sessions in terms of active vs suspended tabs. "Search Tabs" and "Tab Mix Plus" are also very helpful. "Decentraleyes" also helps (mostly latency and privacy) by providing most not-bleeding-edge JS libs, fonts, etc locally only once.

Generally the first 1/3 of my tabs are long term tab groups I keep going back to for reference. These are almost all suspended most of the time they rarely change over the course of a single year. The second third is medium term tabs from projects I worked on but moved on from. I go through every month or two and bookmark projects I won't continue while closing the tabs. The last third is active tabs and changes day to day and week to week. I generally know the positions and relative groupings of all the tabs in the first 2/3 by heart. http://erewhon.superkuh.com/number-of-tabs-vs-date-2017.png http://erewhon.superkuh.com/whathappenedin2016accordingtotab...
I mean, obviously you're right. I guess I just meant that it's good enough for what I'm doing in Python. People don't write verified provers for deep numerical projects in Python, they'd use Ocaml. For digging through a little sqlite collection, parsing through csv files and correlating a few simple features in dataframes, python works fine and the pattern matching that we'll be getting will make it easier to write THAT sort of code.

I don't see Python growing very much more functionally. There's two decades of resisting FP with much vigor, and I expect another two decades of fighting about what little FP has grown into Python thus far.

I'd love to see your transpiler work! It sounds pretty cool.

Compatibility is a double-edged sword, as I'm sure you realize.
Absolutely. To take Ford as an example, It’s not that huge an exaggeration to suggest Ford manufactured cars with virtually no profit margin to help sell profitable loans via its Ford Credit arm at various times in its recent history, rather than providing loans to help sell the cars at profit. Ford Credit is a huge part of Ford’ overall business.
Indeed. SAT is basically "how good are you at cramming a bunch of relatively arbitrary information into your brain and regurgitating it in a high pressure, timed scenario". That is a kind of intelligence, but there are very few occupations where that kind of intelligence is useful. Lawyers and doctors.

Both the "intensely study something rather uninteresting" and "perform under high stress and time demand" are specific kinds of intelligence, and I happen to know many intelligent folks who are expressly bad at it. They don't "test well". Anecdotally, diligent study and fast-testing are anti-correlated in many of these smart folks.

I think the issue is if an article doesn't get enough attention, it's easy for people to slip in blatantly false or misleading information for self interested reasons. I imagine this is worse on non-english wikipedia but it does also happen on English.

So on Wikipedia, you need to always be thinking about whether anyone has a motivation to manipulate the article and checking to see whether they in fact have. You could argue that this is true of everything though, and at least on Wikipedia people are usually pretty clumsy about revealing their biases.

Right, i see two different problems here: json lib apparently leaking, and deciding best format for info transfer.

For the first one: look in specific json lib forums, ask there, check open issues, open issue. (all those stackoverflow questions/answers are really confusers, not helpers).

For the second one: so it's text, i'd transfer text then. It's too much text? Process it in chunks. Your final format is json? Encapsulate your text as json at the last final step.

I feel similarly ripped off by expensive laptops with small hard drives. It would have been $800 more for a 1TB 15" Surface Book 2 than a 256GB 15" Surface Book 2 with otherwise identical specs. A 1TB hard drive is like $100. But you can't really swap the hard drive without peeling the screen off.

This is, in broad strokes, right, but it is hugely reductionist. It is always worth remembering that we're not always in the right circumstances to allow good decisions, and we should probably not judge.

> There is clearly something different about humans.

That's not what this debate is really about. The proponents of "humans are different" are actually thinking "humans are superior". They can make a case for that, but only in terms that confer advantages and entitlement to humans.

Take this example:

> Are aware of the existence of good and evil and have the capacity for moral reasoning

and apply it to an encounter in the forest between a human and a venomous snake.

Imagine one kills the other without provocation.

Which animal was good, and which one was evil?

Let's try that exercise again three more times. I'll give you more information for each case:

1. The human was your pregnant wife.

2. The human was the mass murderer, Adolf X.

3. The snake was hungry and scared, and had a family to care for.
> Incognito is very clear about what it is doing

I don't think so. That label was very intentionally chosen to give off a first impression different from reality, to make it more likely the user intuitively makes incorrect assumptions.

You can call it ignorance, I call it a comprehensive dark pattern. Google aimed to give users the wrong impression. And your cited list is neat but many users have no idea Google, Facebook etc. track users across different websites, and for those it's absolutely not clear what actually happens.

> obfuscating the real concern of targeted behavioral advertising behind an altogether different one.

I don't think this is accurate. I think for a lot of people the privacy issue really is about concern that their behavioral information would be sold and disseminated, and that it is a genuine attempt to address these concerned that Google and other sites are responding to when they say they don't sell private information. Certainly the laws that politicians are crafting (e.g. GDPR and the California privacy law) center the privacy interpretation of people's concerns. If most people were more concerned about behavioral tracking and targeting, I believe that politicians would be passing laws to ban that instead.

I agree that for many commenters on this site, the concern has morphed into a concern about behavioral tracking, but my recollection is that this has not always been the case. I don't think Google intends to address that concern with its statements about not selling private information. But, to address the behavioral tracking concern, Google does have a setting that disables ad personalization: https://adssettings.google.com/.
Selegiline/BPAP decrease ageing by multiple mechanisms:

1) at non-low doses it increase dopamine level/synthesis, dopamine reduce with aging (15% less at 40, 45% less at 70) and this accelerate ageing (can be said of many things, and it also a strong reason for testosterone replacement therapy)

2) it is a potent antioxydant and is pro apoptotic at the mytochondrial level.
This massively reduce accumulation of ROS and is shown to be highly beneficial in many conditions (such as myopathies, and neurodegenerations)

3) there is a third mechanism (effective at low dose)
That is apparently more important than the 2 first mechanisms (at least in rats) and show extreme results such as X2 lifespan in rats and X3-4 learning ability

> I think the flaw here is that HTML is a Chomsky Type 2 grammar (context free grammar) and a regular expression is a Chomsky Type 3 grammar (regular grammar).

Note that regarding formal language and complexity theory, while it is correct that in general, arbitrary nested structures require a context free grammar (type 2 in the Chomsky hierarchy) and are thus beyond regular (type 3) [1], this statement is NOT true _if_ you limit the nesting depth with a finite constant k.

For example, if you agree to an HTML tag maximum nesting depth of, say, 100, then it can be modeled with a regular (type 3) grammar, including correct required matching of opening and closing tags, and hence you can write a regular expression that matches it as well.

This debate is well-documented in the theoretical linguistics literature, where some say human languages are not regular because you can always embed yet another additional relative clause in any sentence in principle without adversely affecting grammaticality, whereas others say while you could you won't find natural examples in human-written text documents where extreme nesting depth is actually found. At that point psycholinguists and theoretical linguists usually start a fight about whether memory limits are important or "just performance as opposed to competence".

(Goes to show how practical solid theory is.)

That's a good question, and your reaction to the Myers-Briggs is justified! It is not evidence-based and is roundly rejected by modern personality psychology. The work the author of this piece was describing on the other-hand is one of the most well-researched phenomena in the history of psychology.

It is based on a massive amount of research looking at clusters of personality adjectives found in dozens of languages that tend to cluster along five dimensions. And the same five clusters are found in virtually all languages (sometimes to include a 6th cluster often called "honesty/humility").

And to your point about types, this system doesn't assign types to people, but instead places them on a continuous dimension that is considered to be much more useful.

And to your point about complexity, the 5 dimensions are higher level structures. Within each dimension is a branching tree of complexity that is where the current work lies.

sorry for this daft question

I imagine a very very slow moving rock in space - going at 1 m/s (relative to earth) in a straight line, the earths mass causes spacetime to bend making the rock head towards earth, but then the rock starts to accelerate

the bit I don't understand is why does the rock accelerate towards mass? Why does the bending of spacetime make it not carry on at 1 m/s towards earth

and since this rock has increased its speed due to accelation, where has this extra energy come from?
