I can think of a REPL use case I don't know how to do easily in another language. Doable yes, but easily and conveniently, no.

I want to build a little tool for the command line: meaning it should be runnable at any time I pull down my terminal, easily started and stopped. In it, I want to listen to a Telegram room. Basically the idea is, in this Telegram room, things are announced, and I want to look up some of them. It could be anything: sneakers, toys, concert tickets. But let's say crypto projects, as there is a running stream of them all day. (Doesn't have to be if you don't like crypto but let's go with it for now).

So I'm printing this list of crypto projects to the screen. Every so often I want to hover over one and get more information about it. For example, pretend there's a project called PGPalooza, one of many that's being printed in this list that's spilling out in real time on my terminal screen. I scroll up to PGPalooza and run a command on it, and then it runs some commands and opens up a few browser windows that I can look at to learn more about it.

This is easy to do in Lisp, in an intuitive natural way, that I don't think I could do with the same ease in other languages. You could think of this as demonstrating the benefits of interactivity in action. I can scroll up and modify the PGPalooza text to read lookup("PGPalooza") and then press Ctrl-E at the end to return one type of data, and financials("PGPalooza") to see another. It's also very easy to modularly add commands to it too, to expand on this.
I live on a large property in a very rural mountain area in the US. My property abuts state land on 2 sides but we've never really had any issues with trespassers, likely because of the first sentence of SoftTalker's comment. Our area is one of the most popular mule deer hunting spots in the Northwest which seems like it could be problematic, but in my experience the hunters are extremely respectful of private property. It's also nice to be able to hunt mulies on my own property and not worry about errant bullets. It is a but unsettling in the last 2 weeks of October (regular rifle deer season) when the local grocery store literally fills the aisles with pallets of Busch Light and Fireball.
There is nothing to agree on. You make measurements, see what model fits best, and then ask the model what will happen as time goes to infinity.

And we did have a consensus: the standard model of cosmology. It fits the data best, that's how it became the standard model. Many cosmologists don't like the standard model, because it has some theoretical deficiencies. One example: The value of the dark energy density seems highly tuned. Its value is unnatural and there is no known mechanism that could produce such a finely tuned parameter. But what can you do if all observations agree with the standard model?

I've been in cosmology grad school ten years ago and would listen to a visiting scientist presenting a novel model that might explain the standard model's shortcomings practically once a week. There is no shortage of speculative models. And as I said, science doesn't work by finding an agreement. You devise experiments that can show that your model explains more than the standard model and let nature find the agreement for you. If there are a few stubborn scientists left that cling to ruled out ideas (Fred Hoyle comes to mind), experience shows that they will die out over time.

Euclid is one such experiment my group studied a lot, and it's finally collecting data. Hopefully it helps us find a better model than the standard model, and with all the news in the past few years, it's looking good.
There are more third spaces in North America today than have ever existed in the history of humanity, both commercial and non-commercial.

Every time someone claims otherwise I ask for evidence but have never received any. (except for the decrease in the number of bowling alleys, ok you got me there that's ONE)

In support of my assertion, I give evidence of the constantly increasing number of public parks, public libraries, and places of amusement like maker spaces, restaurants, and the like.

For example, in the US there are approximately 500 more libraries today than there were 20 years ago. There are, depending on how you count, 100 more public parks.

It is easier and more engaging to be a pessimist though.

It's like how decrepitly old ham radio operators constantly complain about how the hobby is dying despite there being more licensees and a wider variety of projects being undertaken as part of the hobby than ever.

There are things to do and people to meet everywhere, on every street of every city, EVEN IN THE SUBURBS YOU PRETEND TO DESPISE, and people are too busy bitching on the internet about how there aren't to realize it.
If GET requests increase my AWS bill, does that make them not idempotent any more?
It's not really a good alibi; someone putting bear traps on a human path is going to have a very hard time arguing they were trying to catch bears. Someone putting out bear traps without signage is clearly doing something funky; would you put bear traps out in the woods and then try to collect them without signage?

More generally, many states ban the use of steel leg traps by civilians already. They're dangerous to humans (often including the owner), they're cruel to the animal, it lacks any of the "sport" attributed to normal hunting, and they can't differentiate between a bear and an endangered kind of deer or whatever.

They're gonna get weird looks, though. I've spent some time in bear country and I don't think I've heard of anyone trapping them; I don't even think the wildlife service around there does it. They generally prefer to shoot or tranquilize them if need be, because trapped bears are pissed off and you do not want to be in eyesight of a pissed off bear. I wouldn't take any bets about what a pissed off bear is capable of, especially in the ability of a trap to immobilize it.
What most answers here are missing is pointing out the unique difference between a LISP REPL and an interpreter console/shell kind of thing, which is that it fits seamlessly into the languages design. I often see Javascript devs quite unimpressed by a REPL - "I have a console, too". And while Javascript admittedly comes close, its just not the same.

What makes LISP REPLS special is precisely that there is nothing special about them.

There are no extra ceremonies, caveats, or layers that turn a LISP into a REPL. Its conceptually a fourliner, merely replacing the compilers input of parsing text files with reading user input, while providing access to a modified environment after each step. This is possible not because of the REPL, but because of how LISP is designed. It understands going into packages, importing stuff, inspecting values all naturally, not via some "interactive" mode / layer. You are speaking to the compiler directly and it understands your language. For this reason it is much more reliable and natural to embed a REPL in your development process in LISP, than in other languages.
It's perfectly reasonable for me to make a determination and offer my first hand experience about Autopilot's capabilities relative to that of my own and that of other drivers I see on the road.

Accidents might be long-tail phenomenon but driving habits are observable. Autopilot has a consistent, safe, alert demeanor on the road. It reacts to vehicles I as a driver can't as quickly see, changing situations that it would take me an extra half second or more to react to.

Compare that to the average human driver on the road - a third or more of whom you can expect to see holding a phone - and I think it's a reasonable conclusion to say it's already at least marginally better. And if we are talking about accidents, you can't deny that people are generally terrible at choosing the best possible reaction to an emergency situation that happens in the space of a few seconds.
1) Did you mean "Why is UX research not important?", a question, or "Why UX research is not important.", a statement? The word order is different between questions and statements in English.

2) Then again, doesn't matter -- the title should be "UX Research Guide 2024: Stop guessing how your customers are using your product.", like the page it links to (but probably shortened down to fit under HN's max length).
I've done (some? a lot?) of bash scripting and failing correctly in the absence of dependencies is really important. And once you've incorporated them you've destroyed what was good about targeting bash in the first place, because you're back to giving the user a configuration management problem, and if you were going to do them, you might as well have them install $better_language anyway.
> I'm just highlighting how ridiculous the GP comment is,

The one that I specifically described as a meme comment? You're saying it's technically inaccurate? Thanks, criticism noted.
Dane here: Left Denmark (DK) though. It is true that social security in DK is world best. And salaries are high compared to EU standards. Also that leaving babys on the street is probably safe. However the article seems to paint a rather rosy picture. DK has a dark side that no one talks about like "Jante Law", extremely feminine values (good if you like that - very bad if you dont), exclusive culture, very bad climate! Great place to work and have kids - if you stay inside and "play along".
Your bar is much lower than mine, so we won't agree on this.
The crossover point depends on how the weight is distributed between the radioactive material, the shielding, and the radiators.

Collections aren't strictly reference types and with ref structs in generics feature you will be able to write a LINQ-style abstraction on top of Span<T> (though lifetime restriction still apply).

(you could already do so provided it specialized on accepting spans only with element type being a generic argument, with a new feature you could have Span<T> implement e.g. IList<T> and be passed to e.g. Reduce<T, U> where T : Span<U>, and regular struct generics existed for a very long time)
You could level some pretty damning claims against hard science as well due to the ongoing reproducibility crises in academia (LK99, the "faster than light" accidents that have been reported,the "EM Drive"), or the enormous amount of money (and people's brains) sunk into string theory. Somehow those are/were considered science even though there is no evidence.

I continue to believe that the essential challenge in AI is trust, not just capability.

Obviously if you can give an AI system lots of data about your life, it can learn ways to automate and improve it. But do we trust AI companies with that data? Not really, not now anyway.

Ultimately there may be a technical solution to this challenge, kind of like how E2E encryption addresses many trust concerns around messaging.

But if companies pursue capability without addressing trust, they might find a harder time in the marketplace than they expect.
if you consider tax of 45% "zero cost" yes...
In the "you pay your own cost" system of the US, only the rich can afford to bring a case as well. And we have the added downside that only the rich can afford to defend themselves. I would much rather have the loser pays system, even though it isn't perfect.
Fond memories of being mocked for wearing the same clothes I wore the previous year or two. Wait no, not fond.

The clothes were fine: good condition, clean, etc. Just old from the perspective of kids who didn't understand they came from money or that their parents were bad with money and headed toward disaster.

/u/raisedbyninjas was hopefully kinder than those kids even though it sounds like they were in the same cohort by how small $20/month sounds to them.
Any Brits here that can help me understand what the benefit of calling an election before it is absolutely mandated is?

Really interesting co-founder. Claims he made the iPhone? (https://x.com/imranchaudhri) and has a bunch of patents (http://imranchaudhri.com/) apparently made on behalf of Apple along with his colleuges covering things like widgets (https://patents.google.com/patent/US7752556)
This stands out like some of the same things faced in natural science where you don't have to be an entomologist for the primary goal to be to elucidate the complex variety of creepy irregularities thrown at you by nature, whether unexpected or not. Or whether there will ever be a solution/progress or not.

It's a good writeup overall, but it's amazing how this bit applies to challenging scientific problems that have nothing to do with code, so try to read it from that point of view:

>One of the highest-productivity things your team can do is not have any “mysterious” bugs, so any new symptom that appears will instantly stand out. That way, it can be investigated while the code changes that produced it are still fresh in your mind.

>A rare, stochastic, poorly understood machine crash would completely poison our efforts to eradicate mysterious bugs. Any time a machine crashed, we would be tempted to dismiss it with, “Oh, it’s probably that weird rare issue again.” We decided that with this bug in the background, it would be impossible to maintain the discipline of digging into every machine failure and thoroughly characterizing it. Then more and more such issues would creep into our work, slowly degrading the quality of our systems.

>There are many people who say that a “zero bugs” mindset is excessive because, for rare bugs, the cost of fixing them exceeds the cost of living with them. But I find these people are rarely considering the indirect costs of rare bugs – on team velocity, discipline, and culture.

Some industries are so risky that the "zero defects" approach goes back way before there was software involved, that attitude can be practiced on other things besides code, and can definitely be applied to an advantage when coding.

In things like experimental chemistry with a growing layer of electronics, computers, and software on top of it, and where one of the main ideas can be to strive for more "9's", this is another wide opportunity for discrepancy.

Bugs propagate even worse in nature.
50M as a generous acqui-hire maybe.
One commonly overlooked facet of Cannabis is the big difference between indica and sativa. The cannabinoids, and ratios of them, can be vastly different which leads indica to be a ‘downer’ and sativa to be an ‘upper.’

An indica can put me into a lethargic state while a good sativa gives me as much energy as a cup of coffee but provides 2-4x the head rush.

I will frequently hit a sativa vape before going on a run or doing chores because it makes it a more pleasant experience with no downsides. If I were to swap to an indica it would not be enjoyable whatsoever.
Yeah that's not an unusual learning style. No one can learn without struggle. There has to be some reason for your brain to remember something. If the AI is right there ready to do it for you, then why would you remember anything?
We’ve got horses and alpacas on our farm in Ontario, it’s super common for tourists with their hiking poles and huge cameras to venture off the Bruce Trail and onto our land to take photos with our animals.

Obviously they don’t mean any harm, but horses can be super dangerous and a kick to the head is fatal for humans. What separates places like Canada or USA from Western Europe is that here there’s an entire industry of litigators chomping at the bit for a case like that, regardless of how much of an idiot you think that person is. I’m not happy with the system either, but it’s a reality here.

Speedrun hacking.

Very impressive! (the method used in that article's case, that is).
Historically, Maine had excellent recreation policies in cooperation with the private paper companies that owned the majority of land in the northern part of the state: areas not actively being logged were available for recreation access, as were vehicles on logging roads (though you best yield to the logging trucks that drive down the middle of the roads, even if it means you need to dive into the ditch). State recreation fees for snowmobiles, fishing, etc. would cover things like insuring the private landowners against liability.

However, starting in the mid/late 90's, much of the paper company land was divested and sold to private equity land holders (yay modern finance!) and those previous open access policies have been very much curtailed. It's a big loss to the community, but it sure must be making some money for shareholders somewhere...
It is is inversely up to each individual decide if they will abide with their neighbors democratic decision.

The 2FA Game
The existing Conservative government are a shambles at the moment, with a whole series of defections and by-elections. The longer the stay in power, the more it damages their brand. They're expecting to lose this election, and bounce back in the next.

Also, old people are the Conservative government's key constituency. Old people vote more in the warmer, dryer summer months, than if the government waits until winter.
I find all the "Why should I use this when X exist" nonsensical. If you can't see any use for it then it's not for you. There are a whole lot of people who will find this more attractive than Perl.
> (Not coincidentally home schoolers have about one standard deviation of advantage).

Citation required as this is heavily dependent upon the purpose of the home schooling and the resources of the parents.

Anecdata: My cousin was not doing well in 4th grade. So, they pulled her out and her grandmother taught her for 8 hours a day, 5 days a week, every single day.

By the time she came back to school in 5th grade she was doing extremely well and hyper motivated to never go through that experience again. :)

She was, however, the exception, not the rule. So much so that a lot of teachers complimented her and her family on the outcome. Her family had no agenda other than "fix her education". Most homeschoolers do not bring to bear that amount of resource and attention, and they have quite a bit poorer results.
There's certainly a responsibility to follow other applicable laws. You aren't allowed to litter or murder your hiking buddy on private property even if you're allowed to be on it.
I mean charging the laptop does increase electricity consumption. As well as flushing toilets, using soap and towels, and wear on plumbing — and maybe frequent cleaning, depending on the restroom habits compared to transit visitors
Those are useful but they lack the ability to have profile-specific history and bookmarks. I have a completely different set of bookmarks for Home and Work use and would never dream of mixing the two. Profiles are the only way to deal with that, but profiles are themselves difficult to work with.
> lacking motivation

Isn't this for lack of tutors, which AI solves?

With teaching now (even via videos), there's no way to present material for 30 students when they vary widely in background understanding and attention span, so only the high middle gets targeted. This creates a vicious cycle where the spread only gets larger as students age.

If slow kids can be tutored to catch up, they'll be much more motivated as part of the class, instead of the losers. If fast kids are given a taste of how ignorant they remain, they might have more sympathy for others, and might try to help instead of compete.
Right it is good as a “regression” test framework. AI isn’t needed for this and there are things like pyarttest that give you the same regression benefit. - they don’t validate that the initial code was correct.
Any details on this number? I wonder if it accounts for the contributions from the decay products of Pu-238. Would the decay products even matter much?
Having travelled extensively, I've observed that Americans, in general, whether themselves travellers, or living in the US, are significantly less aware of other countries and cultures than any other major country. Absurdly so.

Further, those that have some awareness, or what I'd deem is an ordinary level of awareness, are very typically from either the East or West coasts.

I've reasoned this makes sense, as those living on the coast are more likely to encounter foreigners, or travel themselves.

In Europe, or for example most of Asia, by contrast, awareness is significantly higher, across the board. And when it isn't, the attitude is so different;
much more curiosity and tolerance, less superiority or arrogance, if any.

This only makes sense to me, given other geography's versus the US, which is somewhat in its own kind of geographic bubble, and a pervasive culture which, extremely arrogantly, believes the country is "the greatest on earth".

If the US people didn't also continually support ongoing violent conflicts in parts of the world they have no business involving themselves in, I'd regard this myopia as largely benign.

But that's not the case. This aspect of the American psyche, and the votes it directs, remains a significant concern to the rest of the world - and I will continue to call it out as such.

It can get tedious and annoying, but I don't think it actually affects the likelihood that you'll implement something wrong. The RFCs link to each other when needed. Also groups of RFCs often get combined and edited into a single revised RFC for simplicity.

This makes me wonder: How could the IETF's approach to standardisation be improved? I'm not sure how to fix this problem without overhauling everything.
You can time the election for when you think it would be optimal for you. (e.g. a summer month will mean students will be at their parents which swings university cities more conservative)
