The set of all &T is larger than the set of T.

Let’s consider the case where T is u8. There are 256 inhabitants of the u8 type (0u8-255u8).

Now consider &u8. Each u8 referent is still some value between 0 and 255, but the number of references you could have is dependent on the pointer width of your target system — let’s say 64 bits. So that’s 2^8 possible u8 values times 2^64 possible references, or 2^72 inhabitants. Well, minus one to account for null, and I’m probably missing other details, but you get the idea.

So going from T to &T introduces structure in the same sense that going from T to (T, U) does; and going from &T to T destructures in the same sense that going from (T, U) to T does. That structure may not be directly observable (as in the case of a reference: you’d have to go out of your way to observe the underlying address), but conceptually the structure is there nonetheless.

Edit:

Another way to look at it is this:

Consider a Rust “newtype”, like struct Days(u8).

If you pattern match on that to obtain the inner u8, we call that destructuring. Destructuring is to reduce or break down the structure of a thing, so the opposite must be building up structure, or “restructuring”. Therefore going in the opposite direction — stuffing a u8 value in a Days - must be restructuring. In this case both types have the same number of inhabitants (256); regardless, one direction is destructuring and the other direction is restructuring.
> on top of this is the accent discrimination

This is already illegal in any decent country. It's certainly illegal in at least the US, Canada, UK, and Germany. Assuming the person can actually communicate well enough for the job, discriminating on the basis of their accent or how they talk amounts to discrimination on the basis of racial, ethnic, or national origin.

It's often one of the textbook examples of what not to do.

> sometime just not having the same “local culture” is enough to be subject to that [...] other type of discrimination is political one

People can, and do, choose their politics. And a person's political opinions can say a great deal about their character. If someone believes some particularly evil or regressive thing, I don't want to employ them or work with them. Yes, it's discriminatory. But not all discrimination is necessarily wrong.

With a lot more caveats (since "poor cultural fit" is often code for "not the right race") the same thing can even apply to culture. I'd like to think I'm pretty open-minded, but if you employed someone from a completely different culture, with no previous experience in the culture of their new workplace, and no willingness to try to learn and adopt to local norms, it's just going to be an ongoing mess of confusion and misunderstanding for everyone involved.
Check your perspective. Taiwan, Hong Kong, Singapore, Japan, Korea all industrialized faster and have a higher standard of living than China.

It's less idiotic if you assume the bias goes the other way. People who stick with online poker had better cards in the beginning leading to them early winning and continuing to play. They then experience a reversion to the mean. Those who lose too often too early lose interest and sign off.

They say the worst result to get on your first roulette spin is to hit your number.

Obviously, these are just trends among people. Some gambling addicts never won and skilled poker players won't go on tilt after 20 bad hands.

It's an unpopular take, but I think Debian is less than ideal with how they secure packages. Per-package signing is not the expectation in Debian-land, and the two main ways of signing packages aren't supported by the main repos. They strip the code-signatures even if you submit a package with them. The usual response I receive is "the package hashes list is signed so it gets security by proxy". What about software obtained off-repo? How do I know that the code the developer wrote is what I am running? Package signatures give us that ability. RPM has adopted per-package signing as the default years ago, why doesn't Debian?
You need text to scale and reflow to device width if you want text to be readable. This is one of the main reasons for mobile web design. Else you're stuck panning around the screen to read the text zoomed in.

Once you decide to scale text to device size so that it's readable, you are stuck doing the rest of mobile web design (fluid layout).

Because God forbid first class people have to walk extra long!

Here's an unethical life pro tip. When I fly for business, I intentionally wait until the final boarding call to get on.

Why?

Because then I would sit where ever I felt like on the plane! Extra leg room aisle rows? You betcha! Since I fly red eyes often, this would sometimes get me 3 seat rows to myself.

One time I got extra bold and just sat in an open first class seat. Managed to go half way before the stewardess said I shouldn't be in first class. She didn't make me leave however and I wasn't drinking their booze.
If this question interests you, doing a search for "airline turn around time statistics" is likely to take you to lots of interesting discoveries.

As is commonly the case when one looks at a giant industry and says "I could do this way better having thought about it for 30 seconds" this is a far more difficult problem to optimize than it appears on first glance.
I haven't seen that in years. I think it was 727s used to do that pre-jet bridges. But I guess some models in some airports can still do that.
Ha ha ha, coincidentally I just explained this to my son on a recent trip. There are seven levels of boarding classes for Alaska Airlines. Seven.

Seems simple if one cares to admit it: Status.

No judgment here, even though we were in fact in the last category of seven. Not needing extra time for kids/elderly, not premier, not business, not military, not strata du jour...so yes, our category boarded from the back to front! Sort of... :-)
PepsiCo Unveils Fleet of 18 Tesla Semi in Sacramento
I was co-founder at an ecommerce site, Ruby Lane. We initially launched with a commission model also, but after a few years of pathetic income with hundreds of dealers, switched to a monthly listing-fee model. We lost many dealers from this, but it put us on a path to profitability within a couple of years.

The advantage of a listing-fee model is that your site is paid for displaying and managing the online product listings - not for selling them. If your listing fee is reasonable (ours was a quarter a month), sellers with high-quality items at reasonable prices will do well and will make more money than they can on a commission site. You can let dealers and users talk with each other however they want, going so far as to publish dealers' email address if they choose.

Commission-only sites tend to have lots more listings, but they also tend to have higher prices and junkier items, because there is no disincentive against these; listing fees are that disincentive.

As you have success with this pricing model, you can modify it down the road. For example, for example, charging higher listing fees for more expensive items.

Good luck!
Information is an illusion. What are you going to do with pure information? Nothing.

For information to be worthwhile it must be actualized into physical reality.

There is huge practical evidence for this. China. The technological rise of China is unlike anything ever before seen in history. The reason why china rose is because of the massive transfer of industrial knowhow of manufacturing aka the actualizing information. We gave them the means of becoming powerful while we ourselves moved higher up the stack.

> The Javascript issue never made sense to me. [...] Even releasing the spying software under GPL wouldn't stop it from spying on you.

Exactly.
The licence is not the only problem with javascript on the web because you can't use your freedoms in practice anyway since the code is automatically downloaded and executed when you load the page in a common web browser.

What we need is something that allows people to choose what code to run, similarly to how software traditionally is downloaded and executed in two separate steps.
We need to get away from the assumption that people will run all code you throw at them when they visit your site.
Then maybe licences on javascript can start to make more sense.

Yeah I agree. Macros can be used to avoid some of the typing in defining the interface when the implementation really is common, but unfortunately that makes it harder to document the generated interface. I wish doxygen had some way of supporting comments for macro-generated interfaces.

In defining the implementation, it's easy enough to do something like this (if the implementation really is common):

static int pdf_ll_foo_impl(pdf_ll_ctx_t c, pdf_ll_type_t t, ...)
{
//real implementation goes here, perhaps switching on t
}

int pdf_page_foo(pdf_page_ctx_t c, ..) { pdf_ll_foo_impl((pdf_ll_ctx_t) c, PDF_PAGE_TYPE, ..); }
int pdf_pattern_foo (pdf_pattern_ctx_t c, ..) { pdf_ll_foo_impl(pdf_ll_ctx_t) c, PDF_PATTERN_TYPE, ..); }

which you can also use macros to help generate if you want to.

Personally I don't find it odd that someone might reject "mainstream reality" as not credible. But what is odd are the things they often choose to replace it. E.g. 4chan ramblings or general internet randomness. It's like, be super skeptical, fine, but you don't get to be selective.

I guess let’s see how this ages but I can’t think of any sober analysis that would lead me to that conclusion. Who’s leaving, with such desire and the means to do so? Who’s desirous of coming in? What’s the strength of motivation in first group vs second (how much gain vs loss do each have at stake)? The numbers seem severely lopsided.

It's not that women are "ok" about being called "latinos". In their language, this word refers to all people, irrespective of gender.

In a sense, women have their own specific word "latinas". Men don't have a word specific for them.

There's Google Play Pass.
I hope it goes well, but I'm concerned that they've never done a test flight or a full-duration 33 engine static fire on the first stage booster. SpaceX has always been about real-world testing and rapid iteration based on the (often catastrophic) results of that testing. I worry that the lack of testing is due to a business desire to avoid the (stunning) cost of building and losing 33 Raptor engines on each failed test article, rather than an engineering judgement that such tests are not needed.

> America operates on the principal that it is better to fail quickly and rebuild than it is to defend what’s not working to preserve the status quo for as long as possible. In a century marked by rapid technological change, it is probably better to hybridize the American and European approaches, allowing faster bankruptcies and more flexible job termination in Europe while also providing a more generous safety net in the US.

So you want to ban carry-on luggage so you can get seated 10 minutes faster - guaranteeing that every traveler needs to spend another 10 minutes at their destination waiting for their checked bag to show up at the baggage claim. How does that make sense?
Oh hell no, not when airlines charge huge fees for checked bags. If I’m away for less than a week I move heaven and earth to get everything into a carryon, and most people seem to do the same. You can’t blame us for responding to incentives.
What I don't get about all of this is that the hard, expensive part of nuclear power is building + certifying the plants. Once they're up and running, they produce essentially free, zero-carbon electricity, safely and reliably.

So why turn off the working ones if you're anti-nuke? Why not just stop new construction? They're going to burn coal instead, which releases vastly more radioactive material.
And the countless grifters on youtube DEBUNKING and SLAMMING starship. I think there's a channel that is basically just living off debunking spacex at this point. It's a really weird phenomenon.
Not only the fees, but also the wait at baggage claim for a bag that never comes...

What I do not like in these discussions is that there are always a bunch of fellow Europeans, trying to link economic success to economic inequality.

1. Nothing says it has to be this way, and taking the big picture of history in perspective, it definitely is not that way.

2. Inequality comes in many forms. Corporate and financial culture in Europe pretty much says that you are only allowed to be an entrepreneur if you are born in the right (i.e. rich) family. It is a much smaller club. The European corporate culture is also one with a much stronger hierarchy between the workers, the managers and the executives. In Europe, university degrees and other forms of bureaucracy further inhibit career progress. Glass ceilings are much, more prevalent everywhere, many of which would be illegal in the US. The salaries are lower and the taxes much higher. All of these are also forms of inequality. This talk that compares the beggar on the streets with Elon Musk is a bit myopic.

Whenever I've checked my luggage, it has more often than not been at least temporarily misplaced, if not permanently lost. I mean this literally -- more than 50% of the time, something has gone wrong.

I know that I'm a data point of one and am really just unlucky, but regardless, I am quite simply never checking my luggage ever again.

I have to imagine that if carry-ons were banned, and thus the amount of checked baggage increased, more luggage would be lost. Also, more time would presumably be spent waiting on the tarmac while the luggage is loaded, so all this "saved" time would really just amount to more time spent sitting there doing nothing.

So yeah, this suggestion is a hard pass from me.
