If you can't be as productive in a memory safe language you're bad at what you do

Use Rust. Package management is awesome

Pick some set of university compiler class assignments.
Or apply for a job at Jane Street I guess

Good luck trying to use C++ symbols from another language.

what C++ symbols

>If you can't be as productive in a memory safe language you're bad at what you do
It's about the design philosophy, the developer is always right.
Even when what they're trying to do is shoot themselves in the head.
Some fucktarded borrow checker should have zero authority.

God i fucking hope you will never code airplane shit

If you're doing anything with that kind of reliability guarantee you're using MISRA C or SPARK not fucking Rust.

>Not fucking Rust
...yet

Basically, C++ is significantly harder to use from other languages compared to C.
What are you even trying to do?

>C++ is significantly harder to use from other languages compared to C
There are like a billion ways to call c++ to Python (as he wants Python). some piss easy like ctypes or pybind11. its really not that hard

No, Rust will always be inadequate for these purposes. It's simply too complex, too complex for program verification and too complex for the compiler itself to be verified. Whatever the merits of Rust may be, this is not one.

Ahhh... Maki....

>ctypes
Doesn't demangle names.
>pybind11
I'm only seeing support for a single version of the language. C++11 is very clearly pointed out, but C++14, C++17, and C++98 aren't mentioned.

Yes pybind11 works with newer C++ versions

extern "C"

Have you ever worked in a team with other people?

Holy fuck that's autistic

>The constructs that formally verify safety are too complicated
>Let's use some empirical rule of thumb from 90s
Basic Rust isn't too hard. When it starts to stabilize we will see other compilers and lingers and the like. Also you can probably convert a lot of MISRA over to Rust and not use other constructs it provides and be just fine if you truly believe it does too much

We conjure the spirits of the computer with our spells.

Pybind11 supports C++11 and newer. C++98 is explicitly not supported. It's fantastic by the way, I use it very often at work.

You can shoot yourself in the foot of you want to in Rust, just use unsafe

That's like saying C is a genie and takes the worst interpretation of what you wished for

Normally I'm cool with C on small projects, but everything I'm working on now is large enough that there is no tolerance for error (backend for a startup, so failure to keep the books and track payments could land me in legal issues, more issues but domain specific enough that I won't doxx myself)

Is it possible to activate the autocomplete feature in dr racket everytime you type something, like in the jetbrain IDE's ?

ok?

>While a more modern slimlined take on C++ would be interesting, rust isn't it.
Why would that be interesting? Why not just use the features you'd like in C++ and not other parts?

A barebones text editor for the 3ds
There's already Notepad3DS but I'm sick and tired of having know by heart and type the exact path of the file I want to open, simply because the dev didn't even took the time to implement a file selector
I'm an absolute shitter but I still managed to do it, why couldn't they?

those features could be cleaned up significantly

>Compiler should be formally verified for correctness
>Compiler shouldn't formally verify what it's compiling for correctness
Hmm

A tomato!!! So cute!!!!!!

Cleaned up how? Do you want shorter types or a cleaner interface?

Some features in C++ are poorly designed, either because they happened by accident, or because the committee has to worry about backwards compatibility.
Personally, I'd like less hacky more powerful and terse metaprogramming.
You shouldn't ever have to write boilerplate.

There's other problems too, like the lack of a standard integrated ABI.
Starting from scratch, while for the most part unfeasible, solves a lot of issues.

fft wont fucking work

Sounds pretty neat, you should check out Rusts macro system if you haven't, pretty good about reducing boiler plate IME

What language? Are you doing it from scratch?

caml.inria.fr/pub/docs/oreilly-book/html/index.html

A program is always correct until you specify the expected behavior.

I've seen some.
I was looking for COM examples and came across a rust COM library.
I will admit rust's macros are neat and make me somewhat jealous.

im learning Laravel
give me your worst insults

codingame.com supports OCaml.

ASP.NET Core is objectively superior

Is there a good chance to receive an internship referral if I've been contributing to a company's open source for a couple of months? Who should I contact in that case?

Are you only a programmer if you are paid to do it/have a contract with someone to pay you?

Sure. Most companies have a career page, just toss your resume on there and say you've been contributing

What are you talking about nigger

Laravel is fine, it's the reason why PHP is usable at all.

yes
>dude are you getting paid to work on these libraries?
>nah, but I'm really interested in them

>fix a bug in a open source library you're using

if everyone thought like you, open source wouldn't exist

genius move, to be honest

>muh open sores

>muh closed sores

proprietary software makes way more $$ than open sores

stay mad

they had to get someone to write their documentation, i mean have you seen msdn?
open sourcing it at least barely improved it

learn metaeconomics
money is just a shit abstraction over power
people being dependent on you, on the other hand, is power itself, and not an abstraction of it
open source software is inherently more powerful than proprietary software

you were already in the red when you finished the first version. Python isn't any easier than these other languages!

agreed

jesus christ there shitton of theory about design principles and patterns when writing your program
what the fuck do you guys follow any of those?
i kind a just separate my program by files and thats it

>open source software is inherently more powerful than proprietary software
that depends on how many people are using your open source stuff to even be dependent on you
protip : way less than they use the proprietary software wich makes it more powerful than open source

Pay Attention and Avoid RSI Design Principles
>do a thing
>it kinda sucks

seriously why the fuck don't more people use lua(JIT)
it infuriates me
lua was literally designed to be an easy language to learn
it's also a good language (bar arrays starting at one)
with enough advanced constructs to make development quick and easy
it has everything going for it but almost no one uses it

why the fuck did python even get popular
python wasn't even designed as a programming language in the first place

I worked with someone who exported all data in char arrays and xorred ints with enums

In C#

can someone explain to me why is python and javascript the most popular and fastest growing languages? what the shit even javascript is going down but python is trhough the roof

Attached: stopit.png (965x445, 119K)

Why is Nim so based bros?

javascript is too integrated into the modern internet to ever die
it's a cancer so much worse than the things it replaced

python is popular because it has a shitload of libraries that solve ever problem ever and a language integrated package manager
no idea how it got popular enough to get all those libraries in the first place though
so fucking bad

How the hell do people seriously code in Vim? I couldn't even save and quit

JS not cancer. It's a really nice language.

Obviously not a reply, just forgot to type in 'delete'

Python is only popular because it is so easy to steal other people's code
The language itself is horrendous

my guess is that Python isn't popular as a general language, but that machine learning is popular and if you want machine learning people you ask for Python experience.
in the sysadmin world Python is "like Perl, but with a future" and Lua could be used but its regex alternative has terrible performance and the default binary can't be used for setuid scripts (it has a "run whatever this environment variable says" backdoor), and even if I'm making stuff only for root that concerns me, because someone might take a script and make it setuid without realizing the danger.

is that why there are so many languages that were designed to compile to javascript
people avoid writing it at all costs so they don't have to deal with how nice it is

Im starting a class to learn front end web development and then into some Java.

>compile
transpile

if you think about the logic of it, arrays should start at one because that is the first element of the array. C just used 0 because that first element is at an offset of 0 from the beginning.
When you are talking about offsets, start at 0.
When you are talking about items/indexes/buckets start at 0.

Personally I just always use 0 because otherwise it would just cause confusion with other programmers, and I cannot change how most languages start their indexes.

are you retarded?
