Personally, I have not.

I saw the use of blockchain as wildly inefficient, and now that bitcoin processing is using up more energy than some countries, I think that has born out.

And I still don't see the inherent value of bitcoin. People like to rail against "fiat currency," but bitcoin is also fiat currency; its value simply comes from the decree of a different group of people. I trust the full faith and credit of the US government more than I trust the folks on /r/crypto.
I find that OOP languages (as long as they support FP and immutability) have the benefit of using classes as nothing more that first-class parameterised modules (without any mutable state) so I don't have to repeatedly pass arguments from one function to the next but can look them up from a shared context. Haskell doesn't really have that option, although people have told me that OCaml can do that.
> Zombie businesses required to pay more for labour go bust.

They may survive for a long period of time in a perma low interest rate environment where debt has become cheap and stocks are highly inflated. Low interest rates, as well as enabling debt accumulation, also float the stock market, which provides shareholder dilution-based funding to businesses that otherwise would have far more severe problems.

Uber is an ongoing example of that. Previously they abused venture capitalist institutional money to get by, now they're living as a parasite on shareholders (who are hoping that something changes about the financials in their business, some day, some how).

Tech hasn't had a good 'ol brush fire clean out of garbage in a long time now.

Companies like Snowflake that are bleeding enormous sums of money, would collapse in a traditional 1990-1991 or 2001-2002 style recession. Snowflake is similar to any number of supposedly fast growing, huge loss-making companies like Exodus Communications from the dotcom era, that imploded when the music stopped (and so many of their business clients pulled back on spending). Snowflake's sales over the last four quarters: $851 million, their operating loss over that time: $775 million. They would instantly shatter if a real recession hit, the stock would drop by 95% rapidly. There is a lot of that garbage floating around the tech space these days, because we haven't had any good clearing fires in a long, long time.

Non-Americans would argue that Celsius is superior in every way. What you grew up with will always seem better and more intuitive.

My parents grew up with Fahrenheit. It feels more "natural" and "better" to them.

I grew up with both. Both work fine for me.

The next generation after me grew up with Celsius, which feels more "natural" and "better" to them.

What actually matters in the end is a common standard. And since America is the outlier, they are the ones who must conform.
The compiler doesn't know if the program contains UB or not. How could it? Sure it can have warnings for some well know UB patterns but it can't catch them all. There are dedicated tools designed to detect UB which are not only very slow but fail to be totally effective (they have both false positive and negatives).

So the compiler simply ignores this possibility and optimizes assuming the input is a valid C program.
I agree that we need to hold ourselves responsible for our actions. If it's not going to be facebook capitalizing on our behavior, it will be some other company. From the article it seems that most teens are aware that they have an unhealthy relationship with instagram. Tackling this issue in a sustainable way is something I believe most teens are capable of this with the right guidance.

> Wealth is a false proxy for social status anyway

Wealth is just the current proxy. I suspect you'll never be able to fully eliminate a social hierarchy. Many animals compete physically, humans compete socially, and without money we'll find new ways to socially standout. The game just changes, it's not going to go away.
Yes I think the "social platforms in general" part is key. It's hard to imagine what a social platform would look like that wasn't harmful in this way. Maybe chat apps I suppose, since 1-on-1 interaction is less of a popularity contest.

But anyway, I think the reason that facebook is aware of the problem but doing nothing is not that they are cynically exploiting people, and it's rather that they don't know how to solve it.

"Why," they asked, "should we pay the same amount for a third of a pound of meat as we do for a quarter-pound of meat at McDonald's? You're overcharging us." Honestly. People thought a third of a pound was less than a quarter of a pound. After all, three is less than four!

Why not create a fifth pounder then?

Actually they are relatively cheap to purchase. It’s been a while since I saw numbers, but googling around seems like 25-50.

I also remember something about bulk sales.

If you never intend to capitalize on the gains other then an attack vector it would minimize the risk.

So eliminating someone’s business is 2% revenue * 25$ usd optimally.

Surely we can build a better service to get these costs down.
The Perils of Using Technology to Solve Other People's Problems (2016)
Python and Scheme are the two classic examples of non-declarative functional languages; they are both instructing low-level VMs to mutate machine state, but also both have functional-programming tools and first-class functions. The Scheme (set!) form is a great example of imperative mutation within a functional paradigm.
Yeah not to discourage further discussion but it would be good if admins could add a date to the title.

The actual decision was in April, this is the megathread: https://news.ycombinator.com/item?id=26699106
I'm very skeptical of the technical challenges associated with this problem (business model and financing aside). The amount of delta-v required to perform maneuvers to repeatedly "dock" with different pieces of space junk, and then again to de-orbit is very high. You MIGHT be able to de-orbit on the order of magnitude of ~10 pieces of low-earth orbit debris per mission. Maybe. If you're really good. And low-earth orbit junk isn't the major issue since it will de-orbit naturally in a reasonable time-frame. Higher orbit junk is what really matters, and will require much more delta-v to reach, and then again to de-orbit after "docking".

Allow me to blindly speculate here: a space-junk company is going to take one of the two following paths:

1) Perform low-earth orbit missions to de-orbit a few pieces here and then there, use the good PR to drive funding (let's just assume they can make the finances work via getting governments to pay for it or something). It will technically work, but it will only deorbit pieces that would naturally decay anyways at a meaninglessly low-volume. But the PR will be good and regulatory capture will ensure their investors get paid. The real problem will remain.

2) Go after the really big pieces in higher orbits. These pieces tend to be well-tracked and aren't really a large problem, but all the same outcomes in option 1 will occur. Investors will get paid, and of course, the real problem won't be solved.

Maybe I'm being pessimistic, but I see space-junk removal companies largely relying on the general public's lack of knowledge on how orbits work to drive PR. Maybe Kerbal Space Program 2 will go viral enough to fix that problem? We can only hope
Which would discourage manufacturers from developing a reputation for undercutting their own dealers.

I have tried buying microsoft arm computers since the last two gens now both the surface prox x with qualcomm sq1 and sq2 as well as another yoga book 5g.

Windows performance on these platforms is so trash, you feel like going back ten years on ultrabooks. Even their own apps are not optimized or some like visual studio didnt even run.

Compare that to x86 builtin emulation on apple m1, it performs so close to native performance on a 1000 bucks macbook air.

Microsoft has definitely different priorities like how to chnange settings for a user without their permissions or how to hide settings so users have less choice. windows experience has been so downhill since win7.

Do you have kids? They're ... pretty good at getting germs, masks/social distancing or not. When they get exposed to a pathogen is largely luck anyway.

Nobody's in a sterile environment here. These kids are touching/licking stuff, picking noses, rubbing eyes, you name it.

I'd warm up to that concept if the article was: "We don't know what in the hell is going on here. Here's our source code and data set of x-rays and race. What do you think?"

It could be that in the realm of machine learning, most of what is going on is people turning random knobs on a big machine and getting mysterious results. It's the birth of science without understanding.
This is a difficult variable to control for - especially as it is an open source solution. My hunch would be that many scam sites will use some straight out-of-the-box setups instead of more sophisticated tools like Medusa. But we would definitely address it should this become a problem in the future
It bounces around, thus not travelling in a straight line, thus covering more distance whilst still moving at c.
I asked the authors if they had compared the results with the participant's skin color. They had not. The hypothesis would be that melanin is interacting with X-rays and would explain how the system can classify "race" even at extremely degraded resolutions.

> Israel's real selling point to the US is that it's a low-maintenance ally.

Hm, that's interesting. Israel seems to be the highest-maintenance ally the US has. Other than, perhaps, Pakistan.

I would say that Israel is politically necessary in the US, but they are expensive and prickly.

And I don't think I've ever seen the "closest ally" quote.

We surely inhabit different media worlds, but FWIW that's the perspective from this side. No arguments intended.
You are making a very valid point. For a good amount of time China was not just tolerated, but supported by US business in general. In a sense, Lenin was right about the rope. The trope about prosperity bringing democracy was wrong.

At first, I didn't like bitcoin because of its energy use and lack of regulation (which protects end users, believe it or not).

Rust handles this quite nicely, with the `?` operator, which someone already mentioned in the comments. It's still as explicit as you want it to be, but made real easy by that small amount of syntactic sugar. Maybe Go should adopt something similar.
Yeah you sure would be screwed if that did happen.

But did it ever actually happen before those laws were put into place? Or was it simply the justification of the richest man in town creating a monopoly for himself?

I've always thought that Ruby and Go are on the opposite ends of the spectrum when it comes to design. Ruby barely has a spec; Go specs first. You learn Ruby by experiencing it; you learn Go by reading the spec (or similar) and package documentation. Ruby is interpreted; Go is compiled.

Yes, there are quirks in the Go language but you have to make design decisions.

Yes. People who write in Go value these things. I don't value what Ruby values. And that's okay. My Go programs will require fewer tests and run faster and still compile years later.

It requires a paradigm shift. Automated escrow services could handle almost every dispute where both parties are honest, APIs for validating shipping and handling of goods/egoods could handle another large chunk, and human dispute resolution could handle the remainder.

Such a service could be offered by the legacy payment providers.

I’m surprised to see people disparaging natural immunity. This news about the rhinovirus is great. We should not turn our backs on any method of reaching herd immunity. There was previous news that one of the coronavirus cold strains also provided good immune response to sars-cov2. And of course cov2 itself has proven to produce a very effective antibody response such that those for whom it is less dangerous than flu might consider trying to get infected (don’t take my words as medical advice; talk to your doctor!). I’d consider bringing my young kids to a ‘pox party’ to help get things under control, given the latest evidence. The only reason I don’t still is social pressure, but the science is getting pretty clear that this virus is more like chicken pox than we thought, including it’s age dependent effect curve.

Especially now that we’re seeing that the effect of current vaccines is waining over 6-12 months, it’s time to start thinking more widely as the first people with the vaccine are coming back into risk. Animal reservoir data suggests this choice might be forced anyway - we can’t go vaccinating all the bats.
There's plentiful space all over the universe if you're a multiplanetary species.
The more I've used golang, the more I've had a creeping suspicion that 'the emperor has no clothes'.

Go plays at being a system programming language, but it's really not. It's peers and competitors are languages like java and c#, not rust or c++. When you look at it from that lens, it fares badly. There's just a clunky feel that permeates the entire language, and it's creators seem to have no interest in addressing it.

I've said it before, and I'll say it again. Golang is popular because it was written by Thompson, and embraced by google. You have a whole load of devs that will simply embrace anything with such a pedigree because it 'must be state of the art'
"Euphemism treadmill" [1] is a real problem when medical terminology enters common circulation. Various medical terms have shifted into insult or slur territory over the years - a risky example being "mentally retarded". Note it started as a polite expression used in stead of earlier expressions that already fell victim to euphemism treadmill - and now is understood as an insult. "Handicapped" is an example that went from polite ersatz word to bordering on insulting in our lifetimes.

Not sure if price reduction will do the trick. Intel is behind on the product side.
> Does the ? operator add some kind of stack trace

It depends. `?` will convert the inner error type (the value from the function to its left) to the outer error type (the return type of the function containing this line). That conversion function can be defined by the inner error type. If the conversion generates a stack trace (or adds to an existing one), then there will be one.

Therefore, "Is there always a stack trace available?" is a tricky question-- it was seen as unimportant during the 1.0 days because they wanted to be able to accommodate low-resource environments.

Today, there's third party error handling libraries that cut out error creation / manipulation boilerplate, that might create stack traces for you, and there's efforts ongoing to see how it might be added to the stdlib.
> Wait how many companies are actually using R in the wild? As I understand it, R is born of academia, great for statistics/analysis but breaks down on data manipulation and isn't used in production/data engineering.

It depends, I've worked in some places where R was the core part of their data infrastructure. Data manipulation (of non text) is far, far better in R.

Integrating with other systems can be tricky though, and you don't have the wide variety of Python libraries available for core SE tasks, so it can often make sense to use Python even though it's not as good for a lot of the core work.

Additionally, R is a very, very flexible language (like Python), but without strong community lead norms (unlike Python) so it's pretty easy to make a mess with it.

Finally, when you need to hand over stuff to software engineers, they vastly tend to prefer Python, so it often ends up being used to make this stuff easier.

Like, in R there's a core tool called broom which will pull out the important features of a model and make it really easy to examine them with your data. There's nothing comparable in Python, and I miss it so so much when I use Python.

That being said, working with strings is much much nicer in Python, and pytest is the bomb, so there's tradeoffs everywhere.

No. The reason why insulin is expensive is because the USA has a free market for pharmaceuticals and allows manufacturers to set high prices. The reason why there are hundreds of thousands of homeless is because the USA has a free market for housing and allows homeowners to set high prices.
I don't mean to disparage pandas, which is a library that does a lot of things fairly well. But as an API for data manipulation I find it very verbose and it doesn't mesh with a "functional" way of thinking about applying transformations.

Generally, I've even preferred Spark to pandas, though it's hardly less verbose. Coming from R, it's much slower than data.table and nowhere near as slick and discoverable as dplyr. Its system of indices is a pain that I'd rather not deal with at all (and, indeed, I can't think of another data frame library that relies on them). I hate finding CSVs that other data scientists have created from pandas, because they invariably include the index ...

Handles time series really well, though.

Recently I've been using polars (https://github.com/pola-rs/polars). As an API I much, much prefer it to pandas, and it's a lot faster. Comes at the cost of not using numpy under the hood, so you can't just toss a polars data frame into a sklearn model.
