All available data so far has not shown what you claim, except I believe for the borough of Manhattan (not even all of NYC), and even that is questionable because of all the widely reported accounting shenanigans Uber has pulled with including full prices in their revenue numbers instead of subtracting out large fare discounts or government fares, etc., from top line revenue.

But regardless, nobody would question if a taxi operation is profitable in a small region with correctly calibrated ride supply in outlying areas.

Even if a single company banded together a few such profitable regions around the world, it wouldn’t be surprising.

However, it would be surprising if you claimed that company had a valuation of tens of billions of dollars while operating on annual losses of ~7 billion dollars.

That would make no sense at all.
There are far more people in cars.

Wouldn't the return value of the previous function in the chain make it obvious?

E.g. in Python you can have

def foo() -> Generator

def bar(x: Iterable) -> Sequence

def baz(y: Sequence) -> List

lst = baz(bar(foo()))

It's obvious to an experienced Python user (and to a static type checker) what is lazy here. All you need now is a compiler to enforce it.
the nash equilibrium is weird.

Customers are incentivized to carry credit cards because of cash back rewards, need for a short term loan, convenience of not having to carry cash, and fraud protection.

Merchants are incentivized to accept credit cards because many potential customers carry little cash because it is inconvenient.

And in all this, we are implicitly paying a 2-3% tax for everything we buy that goes straight to the credit card companies.
No individual tax is necessary, but if you agree that government funding is needed then it’s just a question of what you tax. I don’t see why property tax should be singled out as being particularly bad, and the argument you’re making seems to be more like “I don’t want to pay so much” rather than “property taxes are worse than these other taxes.”

Note than land value taxes, a special case of property taxes, are widely considered to be the most efficient means of taxation among economists.

> but the irony or humor or hurt or whatever we are feeling that people might miss in text is somewhat more noticed in person via tone of voice et al

My point is just that, not everyone is good at processing this kind of information. I tend to learn people's vocal intonations as I retain relationships with them. They don't map from person to person for me, specifically. They are unique and individual. It's a magical thing I can manage to understand comedians, but humor has always been much more of an intellectual thing for me, as are most emotions. I can see an emotion on a face, body language, but that data must be aggregated with listening to a person, and not trying to predict how that person feels dependent on previous interactions with different people.

When people are socialized in relatively 'static' environments, it is easy to take all of this stuff for granted because people tend to develop habits that are reflective and resonate of another - thus perpetually reinforcing, convergent - the appearance of 'known constants'. If you've grown up with and have lived a lifestyle where you are constantly moving, interacting with different people, always in different places, always open to what is new - then these things are much more variant. But that also has to map back to some base foundation of socialization you have, because that's where you get the 'reflection' of understanding that continues to enforce a sense of consistency and stability.

I look at all components of a social system to be aware of this, coupled with the modular/analytical/functional mentality of a computer scientist. I'd rather people call it aspergers than anything else, I personally have had far too many labels applied to me in the past, labels that continue to be heavily stigmatized.

Invisible pain, humor, irony...
It only happens if there is no deal.

Unfortunately, “no deal” is looking increasingly likely. While UK rhetoric appears to still be “[The EU] needs us more than we need them”, the EU’s responses have consistently been otherwise.

This may be related to the observation that the UK’s goals and red-lines (when taken together rather than separately) are incompatible with WTO rules.
Thank you, I had the exact same thought.
The New York system was never really "private." The IRT and BMT were designed by the city, mostly built by the city, and were leased to the private operators. The IND was always municipally owned and operated. The city bought all of the systems in 1940, about 35 years after the first one was built.

That is not to say you can't have private systems that work (Tokyo, Hong Kong). New York just isn't a particularly good example.

I realized in responding to someone else that I typically employ a strategy pretty similar to yours. That is, going module by module, decoupling, fixing one compartment at a time, and leaving it better tested (including time constraints) for the next go round and to reduce performance regressions. On a smallish team this works amazingly well.

Haven’t had as much luck with larger teams. Too many chefs and more churn to deal with.

This reads like the lecture notes for a 100 level food science class.

This is pop science, but I think it's the good kind. It's the kind that teaches people, rather than sensationalized headlines about new discoveries or experiments.

We should endeavor to get more people reading these kinds of things. We could make a magazine called Popular Science. Humor aside, I really don't know why this is on arXiv.
I confess to having read the Popehat link quickly (I do not have audio right now to be able to listen to the podcast) and it is possible I missed some subtext, but the link seems more to speak to that the quote was made in a context many today would find disagreeable as part of a series of bad rulings, and that it has subsequently often been invoked to support restrictions on speech as though the existence of some restriction on speech automatically justifies others. Both points are well taken.

But this is quite literally a situation where a person shouts about a fake threat so as to cause alarm in a crowded fora -- the article does not seem to argue that doing so would be legal or that it would not be a permissible restriction on speech.

So I defer to anyone who knows more than I do about speech law -- to be clear, it is still impermissible to (falsely) shout fire in a crowded theater, right?

How Do You Know That Zero Hedge Is a Russian Information Operation? Here’s How
On my first C++ project we enthusiastically implemented customized versions of operators like '+' on new types. It turned out to be really confusing for exactly the reasons you mention.

Operator overloading in general only seems to be practical for mathematical types like sets or sequences where the rules are well-defined thanks to generations of people thinking about them. Yet, even the set case works poorly for C++ because in addition to associativity new operators also inherit the built-in operator precedence rules. For example should * take precedence over + in set operations? (Assuming you implement * for cartesian product and + for union.)

Maybe C++ has changed since I used it but this sort of thing really gets in the way of writing correct code.

I agree with both of you, but I'm not sure if the plants don't want the insect, since this could be a symbiotic relationship and there's some benefit to the plant.

Those who slam spaghetti code. Posit: Lasagna is just spaghetti flavored cake. Too many abstracted layers to fulfill a request. Down the layers, & back up, just to fulfill a simple request.

Autoloading can be expensive as well for I/O until cache is involved, especially with large code pools. Caching isn't optimization.

Trim the fat, reduce layers, use leaner pasta & or less special sauce.

If you've started tweaking costs/time from the ingredients & cooking process (lower level, OS, daemons, etc.) to start then move onto frameworks/libraries; it's less to consume & healthier. Ie., cache invalidation is much faster which should be at the end of your optimization journey.

Fundamentals are being abstracted away daily, while it's great for rapid prototyping & easier maintenance of code. It's imperative to understand problem spaces before delivering a solution.

A very highly recommended book is:

The Elements of Computing Systems: Building a Modern Computer from First Principles

https://www.amazon.com/dp/B004HHORGA/ref=cm_sw_r_cp_awdb_t1_...

The demo scene is a very good example to attempt to mimic with the culture of optimization. It's been bragging rights way early on. https://www.pouet.net/ granted hardware is much faster than it was back in the olden days. But a quick note from admiring their creations you get a taste for older hardware & milking every cycle you can. Maybe forcing younger up & coming devs to use older hardware means they'll appreciate it more & you'll know on current hardware it'll fly.

Another thing to think of is the von Neumann bottleneck & how it was solved (partially) with cache levels or Harvard architecture. I/O is a basis for optimization.

I live in Seattle. I bring cash for cash-only businesses.

In my experience, cash-only stores still exist. Stores that like cash are very frequent.

There's a lot of hand writing about cash users being subsidized by other customers. If it were that significant, we'd expect to see a lot of stores only accept credit card and compete with other stores. They would just be losing a few percentage points of revenue from transaction fees...
One hope I have for the Bitcoin mining bubble is that it will indirectly subsidize improved information systems infrastructure in many remote places as well as improved on-demand chip fabrication services. Once the bubble is gone those things will go to more productive use.

You haven't really provided any data. A few random tweets about incidents, only one about the countdown clocks where the next response offers a probable explanation.

You're trying to sell me on a different version of reality, here. You're telling me a system I rely on every single day is completely unreliable.

Do you live in NYC? Do you take the trains? Go put your theory to the test. Go sit at at a busy train station for 20m and watch the countdown clocks tick down until the train comes. I promise you'll be pleasantly surprised. The countdown clocks are just about the only part of the MTA system that works.

They eliminate all visual distractions, provide privacy, block some noise, prevent others from talking to you directly, and force others to move discussions to a more appropriate place. And they have an advantage over a private office - others don't knock on your door to see if you're available.

I'm pretty sure the opposite is true for credit card companies. The wealthy tend to pay down the balance before interest is even charged, while the poor tend to carry balances forever paying mostly interest while getting hit with other fees.

It is true, however, that wealthy people carry much less risk for them so they may have similar expected values (this is just a guess)

The Workers runtime itself is implemented in (modern) C++, not JavaScript. So, there's no need for a separate isolate -- API objects are implemented directly in C++.

In C++, memory and I/O resources are both managed through RAII. Of course, when binding to JavaScript, we often end up at the mercy of the JavaScript GC to let us know when an object is no longer reachable from JS, and the GC makes no promises as to how promptly it will notice this (maybe never). That's fine for memory (it amortizes out) but not for I/O resources. So we're back at the original problem.

Luckily, in the CF Workers environment, it turns out that all I/O objects are request-scoped. So, once a request/response completes, we can proactively release all I/O object handles bound into JS during that request/response. If JS is still holding on to those handles and calls them later, it gets an exception.

The Shavian alphabet and the book published using it both occurred after Shaw died. His estate funded a trust to accomplish those things; Shaw never saw either.
mikeash makes a different point, one I often make: accepting cash is not free. It's a physical item that can get lost or stolen, which means it needs significant physical security when storing or transporting. There are card-only stores, and I imagine the reason is how much is simplifies their physical logistics. (No need for cashing out drawers at the end of shifts, no need for safes on site, no need to pay a company to transport cash to the bank.)

How much does that cost the consumer? Is it less or more than the "tax" what we pay to the credit card companies?

I did take calculus in high school, but I barely remember it. So I don't understand your notation, if you could explain in a bit more layman terms it would be great. As I understand it, the chance for birth defects goes from around 1% to 3-4%, about the same as a woman in her late 30s/early 40s having a child. I'm not sure if this would compound over generations though, it seems like it would.

I don't really think that my comment was "racist". Just talking about how culture affects genes and vice versa. Was it not bad that the old European nobles were inbred as well?
>Back in 2005 I was at school when a local radio station had a water drinking contest. A woman died.

You're really oversimplifying this, the contest was to drink as much water without peeing so you could win a Nintendo Wii ("Don't pee for a wii"). If you don't pee you offset your body's electrolyte balance and can die. It's not reasonable to expect most people would know this, and the woman that died obviously did not.
This presumed that cash handling is cheaper than merchant fees. Not true for many businesses.
There has been a resurgence in analog and analog-style synths since the 80's but overall I think synth UX has gotten even worse with the rise of software synths.

People often miss the point on why tracking is dangerous, the two comments below included.

The point isn't if the companies behave responsibly or not. Google for example has behaved responsibly with user data, exemplary in fact and I'm sure they'll continue to do so. Yet companies like Google are and will continue to be a danger for everything you know and love.

It's not how you use the data that's problematic, although companies like Facebook should suffer for their blunders, but rather that the data exists in the first place.

Are you part of a minority? Do you have some weird sexual preference or an affair? Are you a woman or gay? Are your religious views mainstream? Have you ever traveled to an Arab country or to Israel? All of these, in the right context, can put your life at risk. It's all an issue of place and timing.

You can also imagine more benign usage, like insurance companies raising their rates or banks calculating your credit score based on where you travel or your movie preferences. Heck, that's already happening.

Yes, many companies can behave responsibly. They can do so today, but what happens tomorrow, or how about in 10 years from now? What happens when those companies are being bought by bigger, less responsible ones. It happened before and it will keep happening ;-)

I think this makes sense. My mental model would have been viewing this as a sharding style concern. Where different sized and topic items would be to effectively different caches. With hit rates determining the size of each cache.

That said, I think I see where I was mistaken in thinking that was an odd example. It was literally the example. Not just a random pedagogical one.

To that end, thanks for sharing! Cool stuff.
