You would stop wearing a bike helmet if:

- It made you top heavy and more likely to crash
- It reduced your speed in half

The tacit implication (or elephant in the room) when someone argues for types and the presumed safety they bring is the severe cost they impose. Now they save some costs too, for sure. But the balance that I see is far, far in the direction that they save much less than they cost. (When applied universally as they almost always are when applied.)
If you can get your hands on the HBS case study of TPS it's a great read. Details how much emphasis is put on blaming any/all issues on process, rather than people. To the extent that if a clumsy worker drops a wrench, it is assumed to be a problem with process, not that worker, and addressed immediately. The case study also describes a couple of examples of assembly line workers pulling the stop levers and how management runs over asap (every minute of stoppage is much money lost) to ask the question "why" five times in order to understand the root issue of the process breakdown.
I've found that one to have a useful purpose in a very specific situation, ie. an endpoint merged with another one and the behavior is sufficiently different that the service replying to the request is not what the requester had in mind. Yes versioning would have prevented that but in our setup, it was not possible.
In high school and middle school you also have a lot more flexibility to devote a substantial amount of time to this type of stuff. You are right, it can result in really technically literate individuals.
They're simply calculating expectation incorrectly. Expectation is a probability-weighted sum over every attempt. While the game of 50/40 is based on a probability-weighted product over every attempt.

Basically "average expectation" for that game is 0.95 (and they give a false name to it).

Tl;dr: it's got nothing to do with ergodicity.

More importantly, they quote "Peters coin game" which has no results in Google whatsoever.
An absurd suggestion because it assumes software developers know how to use computers.

There are ARIA attributes which let you customize the advertised meaning/intent of an element, but there is nothing to, say, mark that a particular location on the page should be considered a button. As far as I'm aware, this matches how Android, Windows, iOS, etc work.

There are so many parts that go into the accessibility of an element, handling tab index, handling keyboard input, handling screenreaders, spoken voice prompting, etc, that a custom solution usually ends up being detrimental to the user's experience.

The shareholder letter from IB CEO Thomas Petterfly regarding the risks of HFT is quite interesting. (Page 14 https://investors.interactivebrokers.com/download/2018-IBG-A...) and copied partially below:

Trading against HFTs and institutions taking liquidity is generally not profitable, at least in the short run. As a consequence,
market participants are reluctant to place limit orders and the NBBO (the National Best Bid or Offer, or the highest limit
order to buy and the lowest limit order to sell) becomes wider.

HFTs are obligated to fill the orders they buy inside the NBBO to the extent of the size displayed. The wider the NBBO
becomes, the more discretion an HFT has as to the price at which it fills the order and, therefore, the more profit it makes
and the more it can then afford to pay for these orders.

The more HFTs pay for retail orders, the more brokers will sell their orders to HFTs and, consequently, even fewer orders
will trade at the exchanges in a competitive market. Also, the more payment the brokers receive for their customers' orders,
the more they can discount the commissions they charge their customers. Hence the newly emerging zero commission
brokers. However, the customer is likely to lose more on the execution price than she saves on the commission.

This is a self-reinforcing feedback loop in which wider markets cause even wider markets, increasing payment for orders,
moving more volume off the exchanges. Indeed, while in 2008 26.6% of the listed stock volume traded off the exchanges,
by 2018 36.3% of the volume traded off exchange.

What is the predictable consequence?

Liquidity vanishes.

Momentum traders drive the markets to more extreme highs and extreme lows in shorter periods of time.

Investors holding margin accounts become less able to liquidate, adding to the price swings.

This is a disaster waiting to happen.

While all of us in the trading and investment community have in one way or another adapted, and would prefer to let things
continue along the status quo, we cannot pretend that all is well the way it is.

We must implement structural changes to the markets before it is too late.
I found these parts of the book completely fascinating, but also the most "scientifically hand-waved" stuff in the whole series. I've never been a big stickler for "hardness" in my sci-fi, but I'd have liked to see the ideas expanded on more. Death's End is a hell of a book, really goes places.

Google makes around 30 billion/quarter on ads. Assuming most of that comes from 200 million users (they have more than that but I assume a lot are not worth very much to advertisers), and their ad revenue comes from a 50% cut of the total ad payments, that comes out to around $300/quarter or $75 a month. I'd pay it, but I think most wouldn't.
Just to play devil's advocate, we don't know how many crimes have been stopped with these systems in place. It's entirely possible that it has foiled terrorist attacks in the past. Making it public (supposedly) would allow other people to figure out how to avoid it and reduce its effectiveness.

Of course the alternative theory that it's there for control and manipulation is more likely.
What we need, in my opinion, is a new protocol. Leave http(s) for documents and make a new protocol designed from the ground up for interactive applications. That solves the problem of trying to shove an application into a document viewing sub-system and should allow for more creativity and efficiency, depending on what this new protocol turns out to be.

What's happening now is like trying to force ftp to show documents, with markup, and forms, and so forth when it's just supposed to transfer data.
Like South Africa in the 1980s or whenever they had nukes? Or possibly North Korea now?

Just because you could wreck the world doesn't really mean that you can get anyone else to do what you want.
> For "vortex" to actually be fitting I'd expect some kind of circular process: perhaps a feedback loop, wherein some process is causing extinction which increasingly leads to more extinction.

That is indeed what it means. Per Wikipedia: "[The extinction vortex model] shows the events that ultimately lead small populations to become increasingly more vulnerable as they spiral toward extinction."

As mentioned there are dozens, and Wikipedia will show you[0]. Since CRMs can be bolted onto just about every business, use cases vary extremely. If I'm being honest, every sales manager starts with an internet search to find the latest rundown [1].

My recommendation is to set aside time to play with a lightweight (pipedrive) + heavyweight (Salesforce) options to see how you might use them one day. I would treat CRMs like a regular piece of software. Many offer totally free trials for 1-3 users. So I would bet they agree with this approach :)

Epistimology is a real pain - unless you can see the future you cannot know except in retrospect. Even the "safe" old option may turn out to not be so with increased understanding so caution in all approaches is advised. We treat cancer with known carcinogens for one.

A friend and I once tried this at a hackathon. If you do it naively like we did, frame-by-frame, you will find that the optimal seam to carve shifts around a lot as the lighting changes subtly.

This results in characters in frame apparently moonwalking around. It's a really cool effect, but not good for actually resizing a film. Might make for a cool bit of a music video.
+1 In a way Trump really is a political genius. He cleared the republican opposition away like so much moldering dust on a piano and then played the damned thing so powerfully he defeated the Clinton machine when nearly every intelligent observer, political scientist and pollster thought his impending loss was a sure thing.

The only other unexpected, unseasoned political opponent to defeat the Clinton machine was another political genius named Barack Obama.

Simply by winning the presidency both of these guys have demonstrated a political genius rarely seen in US politics.
Sure, but the bodies that would attempt to push back against this form of attack sit within the nation-state, not the EU.

"Extinction vortex" and "polar vortex" are both well-defined scientific terms. The media could stand to define them better, but they're generally used correctly.
It's not 50% unless you live in a tight-knit ricer neighborhood. It's not a trivial option to customize a car to make it louder; it takes a bit of effort.

What is true that we tend to notice annoyances more than non-annoyances, and that the car may be louder because the driver want to accelerate or velocitate more than they should, and noise is a side effect. Or the stereo is louder than it should be, not because they want you to hear it, but because they want to hear it and they don't care about you.
Programmers have some say but ultimately it comes from above. The truth is, most programmer would rather add this feature and collect their high salary than rock the boat.

Yes! Instagram has the appearance of a OC/creation platform, but, typically of such platforms (such as twitter/fb) the "content" is low-effort "convenient" opportunistic trivia, and the product consumed is likes, followers, etc.

I couldn't agree more. HTML is so basic that you have no excuse to not do it in the ballpark of right (accessibility can be tricky and right is not always completely clear, but in 90% of cases you should have a good idea). Using a solid css reset solves most of your visual issues with using semantic elements/structuring following proper standards. Use the reset and then write css however you want to. The current state of the web (being nothing but an advertising platform for the most part) is what is driving a lot of people to other protocols. A return to sanely structured CONTENT over pretty/fancy/neat/whatever looking would be, in this writers opinion, a wonderful thing. I know in a perfect world we'd have both, but that is not how things have played out for the most part. Maybe the next thing, that replaces the web eventually, will get it right. :-/
I think spam/scam is reaching a crisis level and it is impacting everyone who tries to communicate with the public.

When Hillary Clinton kicked off her 2016 campaign she wrote an article on LinkedIn proposing that we cut the interest rate for student loans.

At the time I was getting two or three calls a day from "card services" which offered to "cut my interest rate"; these calls often had spoofed caller id. (I think
everybody else was getting these calls.)

Clinton didn't answer her own phone, so she didn't know this, and didn't realize that her message sounded spammy and scammy because people were being saturated with similar messages.

(Lately Ithaca phone numbers, but not surrounding rural areas, have been saturated with calls in Mandarin Chinese. My aspie-linguist friend tells me that the calls claim to be from the Chinese Embassy -- it seems to be some kind of effort to shake down Chinese students.)

For a long time the people I did marketing work with insisted that every web page end with a "call to action" but I think now that is a sure way to come across as inauthentic because I get pushback from readers.

The copy on https://comma.ai/ has certainly changed tone from what it once was.

Now it is clearing pushing a driver-assist angle ("improves your stock ACC and LKAS," "copilot," "augment"). No mention of "self-driving," "autonomous," or the like.

Previously, it was clearly marketing a full-self-driving, no human involved system: "ghostriding for the masses," "software to make your car self driving."

> why was euclidean geometry developed more than a thousand years earlier than the non-euclidean ones?

Because euclidean geometry is the geometry we experience at a human scale.

> Why do we define multiplication this way?

It's not actually multiplication though, it's just a convenient representation of the repetitive addition that is actually multiplication. It's a clear way to show to children that we've taking 9 dots 3 times to get 27. It's a tool to teach and interface to a mathematical concept.

Much the same as why we use rectangular screens instead of hexagons or anything else. It's the most convenient to manufacture and address because of how repetitive and similar each row is when you think about the arrays of pixels that make up the screen. Desks are mostly rectangles because it's easy to cut straight lines and they match well. Then when you have a lot of rectangular items it makes sense for the containers of those items (ie buildings) to be rectangular too so they fit and pack well without any weird gaps and wasted space.

Also I'm not sure where you're coming from with the "bias in our mathematics" most higher level math (as early as Calc3 when you start dealing with multivariate integrals one of the most important skills is converting from cartesian coordinates to spherical or cylindrical because it often drastically simplifies the problem) includes a lot of different coordinate switching to simplify representations to simplify the math of solving a particular equation or reasoning about a system.

This is bit nit-picky of me, but it's a thread I've been noticing lately in some international news, so I'd like to know if anyone has observations or thoughts.

In South Korea, China, and Japan (to the extent of my observations), it seems when some culturally significant norm, craft, or product begins to lose said status, partit chalked up to a result of (what tone usually conveys as destructive) "Westernization". But a significant amount of the advances (i.e., emergent products or norms that have supplanted the ones in question) themselves tend to be celebrated and attributed to the progressive trajectory of their culture & state. It's just an odd bit of nationalistic hypocrisy that gives me an itch.

Of course, I do not think for a moment this is the case for everything, or that their peoples even embrace this view (as I believe to have been conveyed by the media). And I'm sure the West has behaved or.continues to behave in a similar manner, either now or (surely) in the past.

Perhaps I'm completely amiss, which, in that case, all the better.

Yeah right. Big business has done an excellent job of systematically destroying trust in the customer at every step of every process.

> It’s all about what gets consumed by the consumer.

It's not about the what. It's about how it's delivered and consumed.

One could provide a web-like experience using any number of proprietary technologies. It's only "The Web" when you deliver that experience in an open and standards-based way, and consumers consume it using their standards-supporting client of choice.

Podcasts are another great example of "The Web". What makes a podcast a podcast isn't what gets consumed, but how it's delivered and consumed. You can post an audio show on proprietary platforms that require proprietary clients, but those aren't podcasts any more than a web page saved as PDF is still a web page. If you can't play it in a podcast app, it's not a podcast.
I subscribe to the NY Times (and the print edition, anachronistically), as well as a few other outlets. Good journalism costs a lot of money.
> How is the domination of a large agricultural class by a much smaller military class (who were prepared to perpetuate that domination by violence, and did so) compatible with the assertion that before the advent of the nation-state, governments left people alone "so they could pursue their well-being in a bottom-up fashion via social interactions in their local area"?

Because such classes did not develop in every area where humans passed through this keyhole?

> we're talking about the specific concept of the nation-state.

I think the author is using this term in a very broad and perhaps imprecise context compared to you, who appear to be locking it down to a very specific geographical and chronological region.

>The way the stock market is designed (and the fact that stockholders often get to appoint the board who gets to appoint the CEO) means they're going to put short term profits over long term viability. Many companies have been ruined and continue to be ruined by this short-term-ism chase for quarterly and yearly profits.

Short term stock prices aren't entirely controlled by short term results. Just look at PE ratios for growth companies. Short term results often change the price a lot because its an indicator for future results. Stuff like one time write offs don't really affect the price.
Active shareholders are happy to see their stock value rise to unsustainable levels and then selling them to the next suckers.

Yes! This is so awesome to see! And it has nothing to do with the researcher being 13. We are constantly bombarded with loud noises (don't get me started on motorcycles and construction noise) that do long-term damage to our ears. I hope that one day we can regulate these noises in public spaces. Today it starts with study.
If "2 rooms left" isn't true, it's not a nudge -- it's fraud. (The author is misusing the industry term "nudge" in UX, which is about which default option is selected, or which option you're guided towards most easily.)

Honestly I always assumed that on large booking websites, "2 rooms left" would be at least "legally" accurate somehow (like there are 12 rooms left, but only 2 of that exact arbitrary configuration of precisely 198 square feet).

Because if not, wouldn't they be opening themselves to a class-action suit some smart lawyers would be taking advantage of? Isn't that why we have class-action suits in the first place? (Whereas an individual property site, I'm less likely to trust because who's going to bother suing.)

If it's a lie, how are Expedia, Priceline etc. not being sued?
Arguably, it is the best option if you have enough security through insurance; put all your extra cash into some kind of investment.

This is a horribly misinformed article, and is incorrect about the most fundamental arguments it is making. E.g. Among many other issues, it implies that a compromised CA would allow passive MitM.
