Anyone who uses Uber knows the chance of this having to do with discrimination is bonkers. I've closed out Uber and reopened it (usually at the airport) and the price changes rapidly. Has to do with very changing surge pricing than skin tone.

I feel like you can critique that from a consumer POV but pretty dumb for them to write this article + headline unchallenged - when any user of the app knows that identical rides called 30 seconds apart are never going to be the same price.
I’m just getting started with Nix, as it seems more mature than Guix. The argument the article makes is that using a real language (Guile Scheme) over a proprietary DSL (Nix Language) is a better proposition. Can anyone offer any anecdata on that, having used both or either? Does Nix’s inertia overcome its DSL which, while I find a bit ugly, doesn’t strike me as hard to work with?
>To over simplify

What you've described is nothing like a real market. Where are the people in your model who are happy to pay $110? $120? If there are 10 who'd buy it at $200, and 100 who'd buy it at $100, surely there'd be 50 who'd buy it at $130 or so.

That ignores the social aspect entirely, too. How many who were originally willing to pay $100 will later pay $200 when they see others pay that amount for the item and it becomes scarce?
In Settings | General, there is an option, "Ask before displaying external images - This option also disables dynamic email." AFAIK this doesn't pertain to links, just images.

Regarding hooks, at my company we use them to ensure that our commit messages contain our ticket items so work is always linked to our project management tool. I've seen hooks used for running code static analysis to meet project guidelines and generate ctags.

The article is citing a couple dozen studies. Which one is cherry picking?

I wonder how Apple's shareholders would react if the company threw away a market that was worth $1.8bn in revenue in 2020.

Then there's China; 17% of Apple's global revenue, $43.7bn. I don't think shareholders would much appreciate that.

> the public in India would either put pressure on their government or buy iPhones via import websites

The iPhone had 2.97% market share in India in April 2021, down from a high of 3.54% in June 2020. I don't think the people who wanted to buy iPhones but couldn't would be able toput any significant amount of political pressure on politicians.

Rich people would just import them from somewhere else like they always have before, and everyone else would switch to some available Android phone that had the modifications that the government wanted.

You think every email provider crawls links in your email and the inspects the destinations to protect you from spam?

That is patently not true, otherwise you would be dealing with utter chaos as you interacted with the internet. If, as the OP claims, Gmail actually _is_ doing this, then that is worrying but it's not the general case.

Google pre-loads and caches images, which many people consider problematic, but they're not pre-fetching URLs.

You believe the long lasting consequences of doing porn and being a waitress are exactly the same? You've never been involved or talked to a porn performer. Suicide rates for the latter don't lie.
One of my favourite books of the last decade must be The First Fifteen Lives of Harry August by Claire North.

I'll pushback against this point. I noticed that the popular discourse was all about unemployment benefits being the root cause of the labor shortage, when in reality the statistics said differently (i.e., stats from states which had ended unemployment). So I did research to find the true root causes, while I still fleshed out the counter-argument on unemployment.

Hacker News [keybase] proof just broke
Checked a few other users with proofs on their accounts e.g:

* Stavros (https://news.ycombinator.com/user?id=stavros),

* Janisz (https://news.ycombinator.com/user?id=janisz),

* Simonebrunozzi (https://news.ycombinator.com/user?id=simonebrunozzi),

* divbzero (https://news.ycombinator.com/user?id=divbzero),

* as well as my own,

and all of our HN proofs seem to have broken with no profile edits or account changes of our own, and reverifying the proofs isn't proving to be successful in my case. However, it seems to be inconsistent, with users like

* Woodruffw (https://news.ycombinator.com/user?id=woodruffw) and

* axiomdata316 (https://news.ycombinator.com/user?id=axiomdata316)

continuing to have valid HN proofs.

Can anyone else with an existing proof verify or refute this? And does anyone have insight into what might've broken? Comparing working proofs against nonworking proofs isn't yielding any syntactical differences... or really any differences or irregularities at all that could hint at what might be breaking.
That only works if they wouldn't stop if someone were close behind. Sometimes you need to decide which is the worse outcome.
Nix's DSL is just that - domain-specific.

Its laziness + it's record system and all the sugar around it are perfect for a package manager config language.

I love Nix-the-language even as someone who loves Scheme.

Now if Nix-the-language had an s-expression frontend..I would always prefer that. But the core language is great.

I was the conference chair (selected keynotes, MCed). When his talk finished I shook his hand, looked at him and asked something like "did you just resign from the stage?" because I couldn't believe what I'd just heard. And he said "yes", and it looked like it was only just sinking in.

Amazingly powerful moment because everyone there empathised with the experience of being on the right technical track to do something amazing but management not getting it. His frustration was under control, but palpable. And ("anticlimactic" reply in this thread notwithstanding) it was clear we were witnessing something we weren't going to see again.

Hi, I've written recursive descent in JS similar to Brandon's examples. Do you have any examples of what usage of this library (or parser combinators in general) would look like?

Or, an angry parent can call the police and let them know that a 16 year old possesses nose pictures of their 15 year old girlfriend.

Indeed; from what I’ve played with it, it does everything it needs to. I’m a big Scheme fan too, but if Nix does the job, then why overcomplicate it?

> 2) Which raises the question about why the banks aren't blocking IP addresses that Wise uses to log into bank accounts, or at least making a complaint to Wise.

People doing screen-scraping like Plaid will seek out IPs that look innocuous. One place I heard of had bank of mobile phones all with cellular data plans hooked up to some UI automation. This lets them run screen scraping from a real phone on a real cellular network.

Also look at the company Luminati Networks/Bright Data: https://brightdata.com/proxy-types/mobile-residential-ips

They pay app developers to install an SDK on their popular mobile apps, then sell the right to run network requests through users devices. Perfect if you want to do some sketchy screen scraping and need access to a lot of innocent looking IP addresses.
> * Malicious Compliance

I have no problem with the other bullets but this one I disagree with. The fact that you don't have any better choices doesn't justify acting maliciously, even in "compliance," lacking some extreme justifiable revenge scenario. There's a duty to your coworkers and the people paying your wage to at least not purposely act against their interests. If you can't go along with the rest of your rowboat, better to take a long swim to shore before poking holes in the hull.
Creativity generally doesn’t bloom without constraints. If you know you can’t afford to build something bespoke yourself, you have to find a set of tools and needs that are complementary to each other. You have to do it right, because there’s no other option.
If you never reuse an address that makes it easy to ignore those right? I'm not sure how it helps.
Subsidies in theory can work for some problems. My argument is that the US government is not capable of executing them in a competent manner. The collapse of family-run farms is a "downside of abundance" in the same way drowning is a downside of abundance of water.

> Beyond that, it doesn't seem to be in apple's interest to be conservative in flagging. An employee reviewer's best interest is to minimize false negatives not false positives.

I would have thought the opposite. If there is a false positive that leads to an arrest and ruins someone's life, but the public sees that it is a false positive, then Apple will take an enormous hit in the marketplace. Nobody will want to take on the demonstrated real risk being falsely accused of possessing CSAM.

If they have a false negative, it is unclear to me what negative effects Apple would suffer. As far as I know, nobody would know about it outside of Apple.
It is not vfork, it is similar to rfork in FreeBSD but note that fork(), vfork(), and __clone() all invoke clone() in Linux post 2.4. The costs of copying the parent tables and creating the task is the only additional cost for fork(), which is very different than the didactic explanation of fork()+exec().

https://man7.org/linux/man-pages/man2/fork.2.html

"C library/kernel differences
Since version 2.3.3, rather than invoking the kernel's fork() system call, the glibc fork() wrapper that is provided as part of the NPTL threading implementation invokes clone(2) with flags that provide the same effect as the traditional system call. (A call to fork() is equivalent to a call to clone(2) specifying flags as just SIGCHLD.) The glibc wrapper invokes any fork handlers that have been established using pthread_atfork(3)."

This attack does seem easily defeated, even naively, by downscaling by three different means (bicubic, nearest neighbor, Lanczos, etc.) and rejecting the downscale that most differs from the other two, since the attack is tailored to a specific downscaling algorithm -- the attack seems to only be effective against systems that make no effort at all to safeguard against it.

Granted, Apple makes no mention of any safeguard, but it would be trivial in principle to protect against, and is not an unavoidable failing.

Sure, that's easy enough to do: your ship consists of solar sails orbiting the black hole that spread out when they're on the nose side of the black hole, forming an opaque sphere that's incandescent on the inside, and fold when they're on the tail side, letting both the Hawking radiation and the incandescence shine past them. But being able to convert arbitrary matter to useful energy at 100% efficiency would be a pretty useful thing when you're not just beaming it into space, too. For example, it would make it straightforward to power your black-hole-building machine.

However, the trouble with larger black holes like the 2.4-femtometer example is not primarily that they require a lot of mass-energy to produce, but that they last a long time. According to the calculator linked above, it is indeed radiating 545.6 megawatts, which sounds like a lot. But compared to the 808 million tonnes you put into it, it's not very much; it will take you 4.2 trillion years to get back the energy you put in, about 250 times the current age of the universe. (The lifetime calculation on that page is shorter, only 777 billion years, because it's assuming you're allowing the black hole to evaporate rather than feeding it to keep it the same size.)

(BTW, actually that was all for a 2.4-femtometer-radius black hole, not a 2.4-femtometer-diameter one.)

This is really shitty energy-efficiency from a time-discounted perspective. If you use a conservative 3% yearly discount rate, the time-discounted earnings from your power plant over those 777 billion or 4.2 trillion years are equal to their non-time-discounted earnings over only the next 33.3 years. So from an economic point of view your efficiency is not 100%; it's 7.9e-10%, 0.000000000786% efficient. And that's not even taking into account the costs of building the giant gamma-ray laser.

So, for reasonable economic efficiency, you really need to build a black hole with a lifetime of 100 years or less. That means 400,000 tonnes or less, radius of 6.1e-10 nanometers (0.61 attometers) or less, 300 trillion kelvin or more, 102 GeV or more, 2.1 petawatts or more. In nuclear-bomb terms, that's 0.5 megatons per second (still very small compared to the sun's 390 yottawatts or 85 petatons per second), except that it's coming out in 102 GeV photons. That's about the mass of a silver atom, though still very small compared to the Oh-My-God Particle.

As skykooler points out, this could complicate the task of feeding the monster. Maybe you could set it to orbiting at a few kilometers per second inside a solid object such as Ceres, so that it occasionally gulps a proton on its way through the body, leaving a trail of rapidly cooling subterranean plasma in its wake.

Of course, if all the energy that's coming out has to go in through a nuclear gamma-ray laser, it's not really a power source, just a battery that's conveniently portable and has a built-in rocket engine.

Fair point. This housing boom is largely caused by wealthy investors bidding up the price of single family homes, with AirBnb completely unrelated. There are also some urban-suburban migration dynamics at play. I mentioned AirBnb to point out that this isn't just a new issue. And while vacation rentals have always been a thing, they were formerly centered around vacation destinations. Now, they can be anywhere, and the internet makes it possible to browse and compare prices anywhere in the world. It is now economically feasible to own several vacation rental properties in small cities, which creates a pressure on supply for housing locals. And if you can earn a month's worth of rent in two weeks of AirBnb renting, the price of rent for long-term tenants is either going to go up or you are going to switch to AirBnb.
