If that were the case, then "everyone should learn to code" meme would actually be true.

>ADT

Expensive, I prefer compile time generics, which both C++ and D focuses on

Well, it isn't true. Most people don't have the talent to code. You can tell because they don't already know C.

Daily reminder that the final solution to politics, sociology, and economics is a non intelligent computer overlord.

The lead programmer has to be someone who almost everyone in the world can agree is a good person.

The software will have to be able to conduct international trade, regulate domestic trade, counter warfare, uphold law, quell and justly settle internal skirmishes, manage immigration and emigration, provide healthcare, and power itself using the mandatory but well compensated physical labor of the people. This will double as a way to make sure they exercise so that obesity doesn't arise as a problem. Because it's not intelligent and has no emergent properties, and functions entirely within predefined and unchanging bounds, it will be able to do all this with no ulterior motives or conflicts of interest, unlike a fallible human monarch.

It's going to have to have been tested REALLY thoroughly, because after it's deployed, no one will be allowed to modify it. If anyone had admin access to it, that would defeat the whole purpose. Supervised hardware maintenance will of course still be necessary.

Guy from the last thread, so, if I make my fib::Term::Text 'static, it should live throughout the main(), right? Obviously I don't want that.

See the Text should have the same lifetime as i, is it possible to destroy fib::nth(i)?

say i'm a telemarketer and i need to know what phone numbers are active

what is stopping me from going on whatsapp, programmatically adding every phone number and ordering by last active?

Also should I use std::borrow::Cow more often?

'static means the string you reference lives for the whole runtime of your program. That doesn't mean however that the instances of your enum live as long. They'll get destroyed directly after the call to println!()

AI doesn't have to be intelligent to fuck up real bad.

All software has bugs. And with this one, a bug can possibly result in lives, and not just credit card credentials, lost. People will never put up with this idea, simply because they find comfort in thinking that the one who governs them is a human being who understands their concerns, even if they do nothing to uphold them. Then there is the entire issue of how the thing is going to be programmed. The political and social beliefs of the programmer who writes it will influence the way it runs, simply because they will have to make decisions while writing code.

Yes, you got owned, now go back and learn ML or Haskell so you can understand what I mean. You obviously don't know what rank-n-types are so you don't understand the NECESSITY of runtime generics, you've no concept of compiler optimisation or of a separate template system for compilation, and you have no idea what convenient syntax is because you use trash like D

>I got owned and I got angry: the post
Runtime Generics are indefinately more expensive than Compile time Generics. No ammount of ``compiler optimizations" is going to fix it.
>Hasklel or ML
No wonder your ``compiler optimization" leaves you around 20 times slower than C++/D

I appreciate the fact that ActionScript and JavaScript look like sisters.

i program on linux only because of convenience it brings. if you haven't switched in a year, i can see two possible causes:
>you never really tried
or
>you like your windows environment more than linux (though it's hard for someone like me to see why that would be the case)
in either case, windows doesn't somehow "prevent" you from making good software. just learn at your own pace, linux is not necessary, just more convenient for most people.

The part of the filename that comes after the last dot. If there is no dot in the filename, the file has no extension.

I am irritated by your subhuman level of intellect and apparent incapacity of understanding the problem. Are you of African descent?

Can you do this in D? Put this function inside of a data structure.
id = ΛT. λx:T. x

Not a type application of this function, or a specific instance, I mean the
(parametric) polymorphic function itself.

Thank you for your kind rational response. I guess I am lazy to commit fully to it. I also had trouble resizing my ssd and just gave up in favour of the vm.
I really like codeblocks on linux for example. Its far superior to windows version.

this image made me laugh

>Can you do this in D?
The difference between your "argument" and my point is that D does not provide costly polymorphism
>id = ΛT. λx:T. x
Don't know the syntax and don't care. I only care about performance and performance only. I use D with -betterC flag.

How far below 100 is your IQ? 10? 20? 30? 40?

It's higher than you, stupid screeching faggot. English too hard for you?

Imagine having a language even less expressive than Java, and then defending it.

Define expressive

You can back up your work on your vm, delete the vm, your swap and hibernation file. Then just write the disk to a raw image and compress it for later. You can also allocate about 20GiB for linux. You don't need much. Just use arch. It might be intimidating at first, but you can just follow videos online. Keep in mind if you have a uefi system or not.

Able to do this.
interface Foo { T fun(T t); }

>Use modulo in operation cycle, measure full executable no internal language,no using JHM for java.

D literally supports OOP style inheritance too, so I've no clue what you're bitching about with runtime generics and performance, even ignoring the fact that it's not a fucking dichotomy.

how many layers of public static class { void public static main { is this?

>bashing C#
kek I'm probably making more money than all of your families

I don't use OOP, it's not allowed in betterC
Do you even read?

class Foo { template virtual T fun(T t) = 0; };
What's the problem?

:1:34: error: templates may not be 'virtual'

class Foo { template virtual T fun(T t) = 0; };

^~~~~~~

:1:55: error: templates may not be 'virtual'

class Foo { template virtual T fun(T t) = 0; };

>he doesnt live in the post file extension epoch

Interesting, I didn't know about this.

hello fellow c# coder

Attached: 1522981868742.png (1280x720, 602K)

Wrong, that's equivalent to interface Foo { T fun(T t); }
One specifies that a single method is available, the other specifies that a family of methods is available.

>can't even do this
T fun(T t) {
return new T();
}

you will defend this.

I want to be able to run several instances of my terminal emulator with a keyboard combination.
the sane method would be setting a keyboard shortcut in my desktop environment, but I want to do it myself.
would it be a good way to have a program that acts as a parentprocess to the instances of my terminal, or should I change the terminal code so it is one process where several instances run in their own thread? I would choose the former but I'd like to have some input from my fellow programming enthousiasts!
