I disagree, I think the fact Range is polymorphic is extremely useful. Perhaps if your only interaction with it is writing a range of usize's. The only real 'pain point' I've ever had to deal with is passing `&`, but

You don't need to know the rules though, it's impossible to get the rules wrong, the compiler will check for you.

While I don't think that whiteboarding aho-corasick from scratch is a good quality interview. I don't think algorithms and data structures are useless or impractical. IMO a basic understanding of the main data structures is import

This was a year or more ago, but this failed to install: https://aur.archlinux.org/packages/bs-platform/ It's pretty out of date here too. I can't remember if I tried to install with npm.

Just curious, have you seen amethyst? https://amethyst.rs/ I'm wondering what you find not well thought out about it.

Has it been confirmed that the servo team got fired? I read rumblings about this on twitter. If so, that is very sad.

by leshow 6y ago
Apparently they fired the servo devs so you may not be able to support them at mozilla anymore anyway.

Cool, I hope this does well. Last I looked at reason/bucklescript I really liked it, but found the barrier for entry pretty high. The bsc compiler wouldn't even install on arch.

You could just write your will and sign it with a known public key. I don't see any reason why you'd want to keep the will hidden, or require participation to read it

Mentions FP Complete, who worked on cardano I think. So is the accusation that cardano is running a shady exchange and stealing from people? I don't follow the crypto space, but it seems like we might actually want to know which compan

You lose the ability to make sure you've handled an error AOT, but sure, this feature is pretty much the same as a sum type except that it's structural. When I used to write typescript, there were plenty of times I was happy to ha

There is nothing stopping you from returning both an error and a value. Sure, you can just be diligent everywhere and not do that, we know how well that type of advice usually turns out.

You can get all these benefits and not have any of the downsides if you have something like Result or Either, which requires generics. You only really compare Go's solution against exceptions. That's not the only solution that exi

This site is amazing. I had a real problem with nerves during interviews, I did about half a dozen practice interviews on the site over about 2 or 3 months, while I was brushing up on algorithms and data structures in my spare time. It was

Big scare quotes there, you can't really 'prove' much in typescript. Don't get me wrong, it's a nice type system they've tacked on to JS, but it's far and away from proofs of correctness. At best, it'

The guide was pretty good as I remember, I ran Gentoo through most of university. It did take a while from a stage1 install though.

Oh please, maybe if all you're doing is reading hackernews articles. The language hasn't really changed that much in the last few years. The only major feature is async/await.

I gave up on Elm years ago. It's kind of funny, I paid for the Elm in Action book that was partially written like 6 or 7 years ago. I got an email last week that it's finally finished. It's hilarious that the book has taken t

You'll find examples on both sides. Rust is a great example of a successful language growing in the open.

IMO haskells way of defining type parameters with forall is the best option. It doesn't fit with C-style function definitions though. It's kind of a stupid thing to rant over. Whether a language uses <> or [] is the least in

It looks like this is really asking for DataKinds or something similar. Since it's required to lift the enum variant to the type level.

You obviously don't understand, unsafe isn't always optional. You literally can't do some things without it. If you tried to build a Vec from scratch without unsafe for example (or using code that uses unsafe) you would fail.
