It'd be nice if we could move the conversation about Mental Models into "how to evaluate such a model for quality" as soon as possible.

Otherwise the novelty of the most recent proliferation of the term is pushing critics to decide "good or bad" regarding _mental models in general_, which is, to be frank, pretty dumb. Certainly such a dichotomy is much worse by itself than a broad field in which some poor models, applied poorly, are mixed in with a lot of really great examples.

And I guess this doesn't even get into the value proposition of a task like cataloging mental models and/or quantifying them via simple lists...mental models are a core aspect of human psychology and there's really an impressive amount of depth to the topic. Ramming a bunch of them together for quantity seems like a good way to make readers feel either over-confident or overwhelmed.
This sounds absolutely fascinating.

Do you have a diagnosis or have anyone in you family with this debilitating disease? Where do you find the nerve to post such misinformation as this? From personal experience, my family member who suffers from this condition has been hospitalized several times in psychosis and every time he comes out he is glad and happy that it's over and he is back to his normal self. The pharmacological therapy has horrible side effects but spreading FUD like this is way over the line. You also only list the older generation of medication, there are many new ones with less side-effects. Learn a bit a about the alternatives, the neurotoxic degenerative effects of the disease and the prognosis without treatment. With every new psychotic event there is less chance of getting the person back. And, yes they do MRIs and there are visible changes in the structure.
Not to dismiss your work, but do you think the best investment of your time is to write another textbook (assuming this is an undergraduate level book in a relatively well-explored field), or in adding detail/great illustrations/great interactive charts to an existing work?

I know (really, like, I know) how detrimental this would be to anyone's career, and I'm not saying this as a moral condemnation of what you're doing - just curious, as I've found myself that there are many cases in these circumstances where the interests of the author do not align with those of the audience. Just wondering if you feel the same way.

I'm very disappointed with how Quora turned out. It seemed to be on a strong trajectory a few years ago, but has now devolved into Yahoo Answers 2.0. There are still good answers here and there.

How was it key to his success? Is it because Tencent bought a minority share in the company after the company was already successful? Is any Chinese company just called "the Chinese government" now?

Assuming he isn't the only shareholder and some of the others wanted out, would it have been much better to sell a minority share to venture capitalists instead of a Chinese gaming company (presumably for a worse price)? For a non-controlling interest why does it matter?

Assuming investors in these ISAs are rational/smart, they'll take into account the likely outcomes before deciding how much they're willing to pay.

So, even if Lambda sells each ISA the moment it's signed, they're still just as incentivised to do a good job. Because the sale price will be determined by the expected cash flows which, in turn, are affected by how good a job Lambda school does.

It seems just like any other form of factoring: you've got receivables which are due in the future, and you're willing to take a haircut to get paid sooner.

I don't know whether Lambda school provides a good service and/or whether the ISAs they offer are a good deal for the students.

But the point of the article is that selling the ISAs or pools of ISAs weakens incentives. I don't see how that follows. If anything, it makes incentives stronger: if Lambda does a bad job, this will affect the money they receive today (via sale of ISAs) rather than money they'll receive over time (from student incomes).

>I do not understand why GitHub Issues aren't git repos, like most other GitHub collections.
They are probably deliberately avoiding making Github issues available as git repos because they suspect their competitors would copy the format and reduce the effort required to migrate to a different service.
If you use gnome3, learn how. Learn the workflows. Find some youtube demos or something. It is different to what you are used to. I find it very much faster and more efficient to the point that I don't think about it. You basically never touch the mouse, so yeah, it's different.

I used gnome 2 for many years. It's great. Loved it. No desire to go back at all. Did not find Sun moving the main menu item to the bottom left and calling it start a breakthrough in usability at all. I use osx semi-regularly. Not a pleasant change when I do. I use windows almost never and when I do my god the awful.

Try and use any desktop the same way you would use something different and it will be inferior to something different. Good luck.

Resort fees currently enable hotels to charge more than their advertised room rates. It simultaneously gets customers to pay more and reduces travel agency commissions, which are based on the lower advertised rate rather than the actual rate.

I'm rather puzzled as to why FTC doesn't mandate that advertised room rates include all mandatory fees including resort fees.

Failing that, I wonder whether the FTC can place any limits on undisclosed, mandatory fees that businesses love to add to your bill.

I think being confident enough to publicize your cost structure might actually deter competitors. They'll look at it, realize they can't compete on cost and decide to pursue a different avenue.

>I do not understand why GitHub Issues aren't git repos, like most other GitHub collections.

Doing that would make their implementation trickier since they'd have to find a way to make issues play nicely with the git object system which may not be completely trivial. On top of that they have very little incentive to do that because having a custom API and custom tools to access it increases lock-in. If github issues were just git repositories you'd be able to migrate them very easily. I'm sure they very much don't want to decentralize this.

I agree with your general point though, I'm very much a shell power user but I seldom use these tools because they don't seem particularly more efficient than just using the web browser in my experience. As you point out the power of the shell is to combine commands. If I just want shortcuts to list various attributes of the project I can do that with bookmark keywords in firefox for instance.

And to add the icing to your cake, more often than not there are no consequences for those making these bad decisions.
Well, the "why" is certainly "because you use git from the command line; no context switch; CLI is always faster then GUI".

And of course these reasons are poor and hide the fact that with systems like Github (Gitlab and Bitbucket are the same), issue tracking and thelike are locked in. I only know the wiki which can be accessed as git repository (at least in Gitlab and Github). Which other Github "collections" are exposed as git repository?
IANAL, but that arbitration clause doesn't sound remotely enforceable to me. Regardless, that they put it in there is more than good enough reason to not use the site.

Interview with an engineer who worked at a SaaS graveyard
> Just as a matter of full disclosure, I feel that the absence of middle class families does not make an area any more unhealthy than the absence of, say, poor black families makes an area unhealthy. This is very much just a personal opinion here, but every demographic in a nation does not have to be proportionately represented in a community for that community to be "healthy".

I think for a community to be healthy, it must be designed to accommodate a normal person’s life cycle. For 90% of people, that means raising kids, and, eventually, grand kids. Current and future parents aren’t just any random demographic, they’re almost everybody. They’re up there with “people who use the bathroom at work.” A place that isn’t a good place for people to raise kids is literally unsustainable, and that’s not healthy.

The absence of middle class people in New York City, and the tendency of lower income families to leave when their incomes improve, is a strong signal that it’s not a good place for non-wealthy people to raise kids. I don’t think you can call a place that fails to accommodate such a basic life function “healthy.” New York City is literally unsustainable—it would cease to exist if it weren’t for continuous international immigration. Suburbia might be ugly and car dependent, but at least it’s a place where normal people can meet all of their life needs. (Note I’m not advocating for suburbia. I’m criticizing urbanists for failing to offer any solutions that speak to the 90% of people who have or want kids. They’re selling beautiful office buildings without bathrooms.)
Let's apply common sense.

0) First, would it be a good idea to announce your world's existence? Robotic explorers who might exist in your neighborhood might decide your world is worth harvesting or colonizing.

1) If yes, then wouldn't sending a high-power announcement signal need to be obviously unnatural, i.e., containing very little data? Short trains of pulses with pauses that count up in binary perhaps?

1.1) "Visible light" seems like an anthropocentric assumption because there's not necessarily a reason other entities couldn't sense microwaves, IR, UV or even possibly fissile radiation. Furthermore, cybernetic "evolution" seems like there would be many possibilities for different senses. Maybe there is something particular efficient about the visible spectrum, such as polarized laser light remaining distinguishable extreme distances?

2) If said entity wanted to send a little more data as well, wouldn't they use a slightly different carrier or modulation but it wouldn't necessarily reach as far? Or, send it, as mentioned, more slowly?

There is a qualitative difference from model to model. I have a collection of hundreds of my own models, some of which are short and elegant, while others would print out into books easily (if edited down).

It is rare indeed to find a non-obvious, useful mental model that can be boiled down to 5-10 words without losing significant leverage. However the _reason_ why they are boiled down to anything at all is due to a communications burden, such as that confronted while compiling mental models for publishing. That the author offers links to find out more is, I think, a reasonable effort at dealing with that problem.

Let's say your friend asks you to summarize the value of _Jane Austen's_ works while you drive them home from the bookstore. You have been asked by your friend to build a mental model. How much reduction of your experience with the books is reasonable, and where does it lose leverage as a result of the reduction? Yet you have an opportunity to help someone make a great new discovery. This process can be very frustrating for the builder of the model.

So while I appreciate a high-quality critique of a bad example of something, I have to say it seems like those examples are a bit reductionist and possibly unfair given the sheer number of mental models out there for examination, and the reasons for, or conditions under which they were selected for publishing or communication.
Surely there are some teams in the heavily-regulated aerospace and medical technology spaces as well. NASA would apply.
I agree with your criticism of hero worship, and the personal issues with the early pilots / astronauts, but modern space flight is nothing like that.

It's still dangerous, but our success rate with rockets is far, far better than it was in the 1960's. Complex systems, as Hadfield notes, succeed because of diligence and cooperation, not luck and cowboyism. Most astronauts in the 21st century don't have 1-in-4 of their colleagues killed on the job.
Where can I read about this speculation.
I’m curious, what was it that triggered your suspicions?
Reduce shouldn't be considered in the same category as nullish-coalescing. Reduce is on par with array.map. It's perfect for when you have an iterable and want to reduce it down, pair by pair, to one item. It should be used when that situation comes up, and it shouldn't be used outside of it. This is pretty cut and dried.
Yes, planning, lots of code reviews, lots of testing. Building your software so it can be tested. Its all doable but no one wants to spend the money - and if its not critical its good enough.

The pessimist in me would say that Github doesn't have issues as git repos because it makes migrations off of their platform more difficult. Hence making vendor lock-in stronger.

The optimist would say limiting contributions to issues on web platform made the formatting ( markdown ) consistent. So that linking back to issues and commits was more standard, and therefore made Github Issues a nice tool to use over the competition at the time.

You're beating around the bush. If you agree that hegemonic states engaging in imperialism isn't "special", why are you so resistant to the idea that China will behave that way once it has the opportunity? If you ask those in Tibet and Xinjiang they would argue that they already are.

You have some flexibility to take your hands off the wheel for a bit. It nags you after a little bit and then gives you some more time to hold the wheel. If you keep your hands off for too long it will disengage and you can’t put autopilot back on until you put the car in park. You can satisfy the sensors by softly resting one hand on the wheel.

I have a dumb question about this. Under the header 'Torque', where the wrench is introduced the first time, the length of vector F is non-linear with the position of the slider; in other words, the curve you see (that of the length of F) is not straight. Why is that? Torque is distance times force, where is the non-linear component? The article goes on to talk about the angle of the force, but that isn't relevant in that graph yet, is it? (meaning, that graphic seems to suggest we're talking only about a force perpendicular to the wrench?)

> How do I register a Handshake name?

> Handshake leverages a blockchain based on unspent transaction output (UTXO) and proof-of-work (PoW) similar to Bitcoin for naming capabilities. The naming system features an on-chain smart contract-like functionality called covenants which restrict the future use of outputs of a transaction. Because covenants are built in at the blockchain layer via the consensus protocol, the handshake system enables different types of smart contracts which is used to develop an auction system for individuals to bid on domain naming rights.

> What does the Handshake names auction process look like?

> Users can buy or register domains through a Vickrey auction using HNS coins. All possible names are released weekly over the first year after launch. Users may submit blinded bids on the Handshake blockchain anytime after a name is released for auction. Bidding is open to everyone for ~5 days after the reveal period, and have ~10 days to reveal their bid price. A winner is assigned the name and, as it is a Vickrey auction, pays the second highest bid at the end of the reveal period. The winning bid amount of HNS coins is burned and permanently removed from circulation. Losing bids are returned and not burned.

... and you've lost me, as well as 99.9% of the rest of domain name owners.

It seems anything that involves blockchains at all is built by people living in a bubble and completely oblivious to how the real world works.
