>You would want Rust traits Go generics does have this feature. You can require a generic type to implement an interface.

by foldr 2mo ago
Type classes are nice, yes, but SML doesn’t have them, or anything that can really stand in for Go’s interfaces.

Like this, you mean? https://haskellforall.com/2012/05/scrap-your-type-classes Fine in principle, but AFAIK it never really caught on because the ergonomics suck. Interfaces/traits/type classes do seem t

Go lets you constrain type parameters with interfaces. To do anything analagous in SML you have to use functors, which is substantially less convenient. I think people who refer to ML's parametric polymorphism in this context must real

HN threads on Go are boring because they always get derailed by someone grousing about the fact that it took a long time to add generics. The history of this has been gone over a thousand times already and it’s really quite undramatic. The

The generic methods that have been added are essentially just syntax sugar. You can now use method syntax in cases where you could equivalently define a function. They’re not the fundamental extension to the type system that some people hav

Right, that was my understanding, but it seems inconsistent with what I quoted from the review.

It’s the same principle as accessibility. We are all poor programmers sometimes, just as we are all impaired in various ways at times even if we don’t have a disability.

You can easily use arena allocation in a GCed language. With modern GCs there's not usually much performance benefit, so it tends to be limited to hot paths.

You're right that I haven't spent much time thinking about why a project that I'm not involved with, and that is of only moderate general importance, has decided to switch from one programming language to another. Anyone who&

The simplest explanation is that the Bun team decided to try rewriting Bun in Rust because they had some frustrations with Zig. I haven't seen any evidence that there's more to it than that. It's easy to get sucked into all t

Is anyone else failing to understand all the internet drama surrounding this? The rewrite may work out on a technical level or it may not. Let's wait and see. The Bun project did not swear a blood oath to use Zig forever, and it's

Even in Freedomland most people don't carry firearms. What else are you realistically going to do if someone has a gun except run or hide? This seems like a total non-story. Especially in a country with ~30 firearms homicides per year

That’s interesting, thanks. I agree that with all those extra protections enabled, there is no security issue.

Will it not need unsafe-eval, though? It still creates the potential for HTML injection to lead to execution of untrusted code. Execution of untrusted code is the real issue, regardless of exactly how that code ends up being evaluated and e

This is a pretty good argument in the case of software written by a small team of experienced engineers. In that scenario, if the engineers don't have the nous to avoid the kinds of HTML injection vulnerabilities that might allow an at

It means that you have to use a less strict Content-Security-Policy, which increases your vulnerability to various client-side JS attacks.

He can make that case to the investigating committee. If Farage finds that inconvenient then, well, the easiest way for him to avoid such scrutiny in future is to declare any large amounts of money he receives. Not that difficult, and sure

Investigating Farage for failing to declare donations and gifts is neither “lawfare” nor a plausible means of removing him as an MP. It’s just the Parliamentary Standards Comittee doing its job. No legal penalty is on the cards. The worst t

I agree. However, as it's clear that OP is not an AAVE speaker writing a comment in AAVE ( https://news.ycombinator.com/item?id=48880115 ), I thought you were being somewhat facetious.

The system has proved to be quite dynamic, really. The electorate have had real choices over the past 10-15 years. Stay in the EU or don’t. Elect a genuine socialist or a centre-right conservative as Prime Minister. And unpopular or incompe

A does unethical things to B, therefore I can do unethical things to A. This clearly doesn't work as an argument if A and B are people. Seems like classic 'two wrongs make a right' reasoning.

This is obviously true to a large extent, but it is also weirdly necessary to explain basic ethical precepts to a surprisingly large number of otherwise well-educated people. Believe it or not, a significant number of people simple don’t kn

I think the point is that preventative action against crime is unquestionably good to about the same extent that enforcing the law is unquestionably good. In both cases there are exceptions, but few would question that it’s a good thing to
