Learning the meanings of things without learning how to do them leaves you powerless to do anything with that knowledge. It's very easy to walk around saying "we could solve problem X with technique Y", but if you don't actually know how to do Y, then you're just conjecturing fruitlessly.

For instance, here you're talking about "memorizing how to manually integrate a 5th degree polynomial" as if that's something anyone who knows calculus actually does. What it really sounds like is that you don't want to put effort into things. Giving you easier classes isn't going to solve your problem.

Granted, you'll want a broader understanding of things, but the best way to get that is often to actually learn as many details as possible over the long term, not by watching teaser trailers and being told that's the whole plot.
What's so wrong about using the word 'universe' in that way?

You think the situation improved in recent years? Seriously? That aside, I happily muffle the discourse of anyone in favor of deplatforming, since I have seen that used against completely innocent people from some cliques that think they own the place. But don't mind me.
I agree. Similarly, I cannot be forced at gunpoint by the government to provide a cake for a gay wedding if I have a moral objection.
It would be nice to see the long term expected prices of EV's vs gasoline powered vehicles. Currently you can buy a cheap gasoline vehicle and years of gas for the cost of an equvilent EV.

Also i read all this gloom and doom about lithum reserves and how long they will last and how sustainable it is to the point i dont know what to believe. So are the batteries going to get more expensive as countries with lithium reserves realize what they have and start charging more?

I wish i could afford an EV or a hybrid, but they are out of my price range.
This comment keeps saying "[rigorous] formal notation" -- are you implying that new mathematicians might lack rigorous mathematical technique, or just that they won't be motivated to communicate their results in a formal way that other mathematicians will generally understand?

> What if it turns out that white supremacists primary wish is to have their arguments heard by society, but society has instead cast them out and refuses to let them post elsewhere so they can only post on 8chan, and that some of them, mentally unstable, react to being outcast in extreme ways?

The thing is, their argument is often not coherent or unfunded and once public, will be shown wrong pretty quickly (sadly not always with the right words or the right ways) and they'll feel attacked because of that.

On theses platforms, that doesn't happen, people are cheering them, they feel right, they feel it's the correct way of thinking. Thus they go there instead because it feel good.

The best example is r/the_donald banning any opposite way of thinking.

They are also slowly self-justifying isolating themselve from others, accusing others of manipulations, of fake news, using conspiration theories to ignore facts, accusing people of "concern trolling", etc...

That's sadly quite hard to fix and you'll need quite a b it of motivation and original thinking to be able to go beyond all theses walls they build arround themselves to protect their hatred and their little communities.

In my experience it's never "obvious" until it flies across the room :D
Considering how close Julia is to Lisp, it could be interesting to have an actual Lisp targeting the Julia compiler, for people who don't want to compromise on s-expr but would still want to have a performance oriented Lisp with access to a lot of scientific computation and ML libraries (and probably better interop compared to Clojure and Java for example). The only work I know for this is:

Also, there's the top notch animation support. When combined with tools like Flare, things are much more straight forward to create and they are cross-platform to boot.

The Book by Steve Klabnik looks fantastic for newer programmers, but as an experienced programmer I did find it difficult to get into. On the other hand, the O’Reilly book by Jim Blandy and Jason Orendorff is just amazing for experienced programmers (and would be unsuitable for new programmers). It’s the best programming language book I’ve ever read. It’s great that both books exist, filling those two niches.

I don't know why no one seems to think about symbolic programming which was the original killer feature of lisp, and one of the main reasons for doing macros.

In math oriented programming this should be one of the most powerful features and skills in order to simplify and modify calculations. Sure you can implement that with macros and AST but that is not at the level of S-Expressions.

Everything else is not more important as any other competition of DSLs.
It would be pretty interesting to imagine what daily life would look like with only the strong and weak forces, true.

Thanks for this - treating easily-debunked fakery as a boomer problem is absurd. Entire sites like Mic exist to convert shoddy n=8 studies or narrow statistical observations into grand narratives for 20-somethings to believe uncritically.

I've gotten really good at catching misleading statistics. In the areas where I have expertise I have a lot of practice with noticing reverse causation, un-normalized data, p-hacking, manipulated time windows, and so on. Every so often, I see someone cite evidence for a claim I strongly disbelieve that's really convincing, that looks clear and direct and immune to basically all the usual tricks. And it can take me an embarrassingly long time to remember that I should go and check the damn source. Because even in a world of fancy statistical tricks, there's nothing stopping people from making claims that simply don't appear in their source, or outright falsifying the claim. There's nothing quite as irritating as somebody claiming a "twenty year high" in something and citing a paper about a "twenty year low".

And I always wonder just how hopelessly screwed up my - and everyone else's - knowledge base is. If a "vaccines cause autism" claim gives me so much whiplash I check the source and find it's fake, how many plausible claims did I not run down? If I read a Vox article and barely catch a statistical mistake that invalidates the entire claim, how many stories have completely-invalidating flaws I don't catch?

Deepfakes might be important as a way to disrupt some of our strongest forms of proof. Something like an uncut high-fidelity video of a politician saying something atrocious is basically undeniable today. That can help convince people biased against believing the story, or let untrusted sources provide trustworthy contributions. But deepfakes are going to be a mere ripple on the total amount of bullshit; that's been high for decades, riding on totally disprovable claims.
Perl 6 is my go to scripting language. The concerns about code styles don't apply at that point because it's all me. And the multi paradigm nature of Perl 6 means I can solve any given algorithm using a style that fits how I'm feeling in that moment.

I wonder how that plays if the long rumored debt problems actually create some sort of financial crisis.

The US as a foil works, but Chinese internal propaganda also talks about their strength and independence... if there is a serious crisis that hits the general populations, it's going to naturally raise questions that "If Xi and Co. made us so strong ... how is it US sanctions alone are to blame for this?"

Obviously there are options there but just from the outside looking in there seems to be a lot of pseudo "trust in Xi, he makes us strong" propaganda that would suddenly become problematic.
Most beef cattle in the USA are raised on pasture from birth in the spring until autumn (7 to 9 months). Then for pasture-fed animals, grass is the forage that composes the great majority of their diet. Many cattle are then fattened before slaughter in feedlots and are fed small amounts of hay supplemented with grain, soy and other ingredients in order to increase the energy density of the diet (fattiness carcass weight, etc).

(And a lot of this cattle raising is done on huge tracts of land which used to be grazed by Bison, which we nearly eradicated, and replaced their biomass with cow biomass.)

I think its somewhat disingenuous to say the majority of the beef we eat does not come from grass fed cattle. But if you want more purely pasture raised animals, that is mostly an economic argument which is somewhat separate from what's best for the land, etc.

Common Lisp folks should really start designing a more modern version of CL.

I'm pretty sure some old Lispers would come and say, 'Common Lisp's stability is a great feature', 'There are lots of new dialects', and while they are right in some aspects, Common Lisp isn't appealing to anyone these days. (I mean, even C and C++ is improving. Why shouldn't CL?)

Even for people who 'get' the ideas of s-exps and macros, there are too many quirks in CL to appeal to people, and most go to Clojure (where the interactive experience is at best moderate, debbuging support/error handling is a mess, e.g.).

I believe the hypothetical CL++ should at least:

* Straight out incompatibilites between implementations, especially the numerous opinions to make an image or binary, and the FFI parts.

* Design a better CLOS system. CLOS feels like an object system thought after (well, after all it is a system thought after) and bolted on CL with duct tape. I would appreciate a CLOS-based type system (based on macros much like CLOS) that integrates well with CL.

* Remove unused functions, and fixing some inconsisties in the standard library

* Bigger, much much bigger standard library. Crucial, community-standard libraries like asdf & uiop, syntax-sugar like the arrow/diamond macros, and reader macros that allow infix syntax (this currently exists in the standard but nobody uses it partly because most Lisp users don't really care about infix, partly because it's extensiblity is bad) should be in the std.

* A compatibility layer. Providing a 'cl' and 'cl-user' package with the usual CL symbols will be sufficient.

to appeal to the users.

This really isn't sufficient for the hypothetical CL++ itself; there really should be beginner materials that isn't PCL; Lispers shouldn't hate infix reader macros or syntax-sugar like LOOP(IMHO these show the real power of macros, after all, macros are another tool to write readable code with great abstractions) and beginner materials should use, or at least introduce them(infix reader macros and other syntax sugar).

Just a rant about the language after reading the post and becoming sad.
I guess we already made the experiment what would happen if white supremacists would lead a country, so we can already tell that it's likely that "sending them back" isn't going to cut it, if "they" refuse to leave.

Working quickly helps you validate your idea fast and iterate.

Working quickly can also mean not putting enough thoughts into planning and researching, so you just waste your money, your time, or your credibility faster.

Working quickly can get you promoted.

It's not immoral. Belief in free speech includes the freedom to choose which speech you want to support with your private resources. If anything, it's immoral to force private citizens to carry messages they disagree with. If the owners of CF are ideologically opposed to the ideas that 8chan represent, they should not be forced to be a vehicle for those ideas. Of course, booting people from the platform is bad for businesses, so it is wise for them to be as neutral as possible, but they have no moral obligation to support ideas they view as reprehensible. In fact, complicating normal business operations to take a stand against reprehensible ideologies is the moral thing to do.
oh yep im sure cloudflare is under 10% market share and there are plenty of other competitors that are just biting at the chomp to host 8chan
I have written production apps in Flutter and RN. Honestly I like RN better for using native view components AND jsx. Dart code gets really cluttered with parenthesis and nesting and jsx is just cleaner to read me for me. I have also hit a lot of random flutter freeze up bugs (especially with the keyboard) that have been around and tracked for months.

Upgrading in RN really does suck so bad though.
The article mentions another interesting post on the site, which indicates that there is apparently a slight diurnal variation in background radiation levels: https://www.fourmilab.ch/documents/cosmic/

There is some good data, but no conclusion on why this would be the case. Anybody know of any followups that explain this effect?
nice :) any plans to add networking? (or did I miss this)
Does someone know what the state of the RN rearchitecture effort is? And is there likely going to be a smooth upgrade path forward without much breakage across the ecosystem?
As a technical point of fact, Americans can buy tanks, missiles, hand grenades, and most any other conventional weapon if they wish, there is no prohibition under Federal law and an existing process for doing so. In practice, it is a hassle and weapons are extremely expensive so only a handful of wealthy collectors ever dabble in it.

Out of curiosity, do blog owners expect retention from a popular article? I just don't consume content this way. Unless the article is covering a long-term project I might be interested in (following game development from inception to release, etc) or the article sells something to me and I convert to a client, why would I start visiting a blog on the off chance that the author strikes lightning again? I much prefer curation services like HN.
Crucially, if the so-called house of cards in China does crumble, we're likely to see residential and commercial real-estate suffer worldwide. This is the consequence of years of capital flight coming out of the country.

Not only that, but the parent comment wasn't suggesting restricting speech in any capacity, explicitly or implicitly.

Normally I'd ignore a one-off dishonest or misleading comment, but this post has many different comments by you that could be categorized as such.
I think you misunderstand the things I'm saying are talking points. The sad white boy having no place in the world and sexual rejection being a new and uniue problem that justifies disproportionate response, is what I'm talking about. That's the alt-right bogeyman. That's the fuel for a lot of this fire.

As far as I know, parts of the Julia parser is still written in a Lisp variant called Femtolisp.

Also one can run Femtolisp by executing:

julia --lisp
Not to take away anything from the project, but for my particular workflow, the way I get the built in find to work for me is by doing this in vim:

set errorformat+=%f,
command! -nargs=+ FindAll cgete system('find . ' .
\ join(ignored_dirs_find, ' ') . ' ' .
\ '-type f -iname \<args>\') | copen 9

I can then :FindAll some_pattern, with ignored_dirs_find being an array that gets populated somewhere else in my .vimrc with -not ( -path -prune ) flags. As I said this works for me, as I'm much more likely to be doing this kind of thing in vim rather directly in the shell, otherwise I do like to use find directly. I prefer doing this to using dedicated extra tools because I often find myself in a machine I haven't configured and I can just get going right away by either using find's flags or curling a .vimrc. No packages to mess with, no plugins to set up. I guess my point is, it's very handy to ignore lots of things when using find, something which fd and others like ripgrep does by default. I just like to be as portable as possible.

EDIT: Also to clarify the copen bit, this will populate a list of results in a seperate window, making it work by adding a simple %f to errorformat, so it knows just to display a list of file names, then you can either switch to that window or :cnf :cbf to switch between files without losing focus of your main editor window.
I'm always amazed at how right wingers are all "property rights, property rights". And when something like this happens, they quickly switch from demanding that the property rights of CloudFlare be observed, to "free speech, free speech" concerning the conservatives on 8chan.

Haiku Activity Report: Performance Edition
I am familiar with the "slippery slope to utter catastrophe" argument, but I don't really see it as applying here. Passing laws to give rivers corporate personhood won't automatically create rights for imaginary babies (which is how anti-abortion types typically perceive embryos). And patriarchal types are already working to subjugate women just fine without waiting for this.
Even if we aren't irrigating crops directly with seawater, we may have to engineer crops to thrive on high saline irrigation anyways, as there is seawater leeching into aquifers in many agricultural centers around the world, including coastal California. As sea levels rise, we should expect this to be a larger problem and plan for it.
Sure, and again I'm somewhat on the side of banning or very-heavily-regulating guns.

I think it's a little unfair to take the US as a whole for this; the population of the US is 5x the population of England, and it's not a big homogeneous blob. Mass shootings don't typically happen in places like NYC, because there are much stricter gun laws.
It depends on how you implement it. I tend to implement mine as part of a compiler/run time, so it’s just another stage for me.

But my point was that any of those editor parts aren’t really identifiable as it’s own thing outside of editing.
You say political agenda, but your own source lists the most recent vehicle attack as occurring last year, and no casualties occurred. Multiple mass shootings have claimed tens of lives in the past few days alone.
It’s so plainly exploiting massacre as a partisan tool.

The Dayton Ohio shooter, STEM school shooter, and Congressional baseball shooter were all active left-wing activists but there is no equivalent examination and hand-wringing in the media. The activity is clearly unnecessary and just fuels more indignation and division.
I guess this just goes to show further how the proper diet for a person is highly individual.
