I'm a big fan of both homoiconic languages and functional languages, but I don't like Scheme.

It's only a matter of time until some non-English speaking Asians take your IT job.

Given this code and my lack of method knowledge, could I summarize these lines as such:

Stopwatch watch = new Stopwatch();
//assigns the Stopwatch class to the variable "watch" and let's us actually access the Stopwatch class
And of course now that "watch" exists, watch.Start/Stop(); refers to the respective code contained in public void Start/Stop();

I'm on my third and final year of CS and I'm starting to feel anxious about my capabilities. I may have a 4.0GPA, I still feel like I know jack shit about anything, almost all the projects we've done so far are standalone cute sub-1000 lines of code programs, with one exception for our web class where we had to interface with some apis.

For example, I'm a huge retard when it comes to spelling, so I'd like to integrate a spell-checker into Steam's chat. I know it's possible, there's some dude who made a 10 seconds video showcasing it working, but fuck if I know how the hell he did it, and I don't even know where I'd start. How the fuck am I supposed to be employable before the end of the year?

Firefox 60 changelog:
- [FIX] We rewrote the browser using Electron
- [FEATURE] Removed all backwards compatability
- [BREAKING CHANGE] Ran rm -rf * in the git repo. Off to a fresh start!
- [IMPORTANT] This is only part 6 in our long-term plan to deprecate Classic Firefox in favor of Chrome(Firefox). To read more about this venture, see below:

Long-term plan:
Announcing Chrome(Firefox), a brand new browser based on Chrome written in Electron. We plan to maintain 100% compatability with the latest releases of Chrome, while dropping the previous freedom of the Classic Firefox project. This new project will be a perfect clone of Chrome written by the developers of Firefox. While some have voiced concerns over why this project would be useful, Chrome(Firefox) stands out from other browsers because it is built with L:heart:VE (and white male tears). Although performance may decrease with the release of Chrome(Firefox), the project is 10x more friendly to PoC, WoC, Womyn, non-binary, and other minority contributors. As an added bonus, this new project blocks all hate speech from reaching you, the user!

Then what makes you think I need to make a proper argument to dismiss your non-argument?

>>63211611
Because it's obvious and most people already know that Electron is a horrible idea.
You're the one claiming that it's reasonable, so you must prove it.

I've already given my reasons: Electron is just a browser and a javascript engine packaged with your web app, and this means that for every Electron app on your machine, there is a corresponding redundant installation of chromium on your machine.
If you don't see how this is batshit insane, then you're in the wrong thread.

>>63211719
>Because it's obvious
Nice argument.

>you're the one claiming that it's reasonable
The only thing I claimed was that users don't care that it's really running inside a camouflaged, stripped down browser. Whether it's "reasonable" or not doesn't depend on that factor.

>If you don't see that my opinion is correct, you should leave and stop triggering me
Nice argument.

OK, in C++ I have to check if vector has any element but 0 and 1.
For example, if vector is filled with 111000, return false, if 110221, return true.
Fuck, I can't do this shit and I should feel bad.
Just take a vector as argument, iterate through it and check if iterator equals 0 or 1, if not, GTFO.

Am I right or there is more efficient thing?

>>63211759
Yes it's fine. Or you could do it idiomatically using std::find_if and predicate. It doesn't make much difference.

>>63211759
The only thing that can be more efficient is to make sure nothing besides 1s and 0s gets into the vector in the first place.

>>63207581
So I was late to the punch and probably won't get any internships this summer. When should I start applying for next summer? It'll be my senior year so I really need to be proactive about getting experience.

>>63207638
I think it's more about being lightweight, plus if you're forced to deal with the stuff that IDE's take care of for you all the time it'll help you become a better programmer.

Trying to get my head around blockchains.

At the simplest, it's just a bunch of blocks containing (previous_hash, application_data), and a hash over those items? And then that's passed around and more blocks are made using that block's hash as previous_hash?

>>63211759
std::find_if is your friend. Also don't take std::Vector directly, take vec.begin() and vec.end()

>>63211993
Just apply to full time jobs at this point.

>>63212054
Wouldn't I be more likely to land an internship than a job after I graduate?

I have also read that lisp is a good language for this. Is it so? I'd like to learn lisp

Is «Paradigms of Artificial Intelligence Programming: Case Studies in Common Lisp» a good book?

>>63212414
> Is «Paradigms of Artificial Intelligence Programming: Case Studies in Common Lisp» a good book?
Isn't it from the early 90s? It's desperately outdated for such a fast-moving field.
> I'd like to learn lisp
Why? Lisp has nothing to do with AI for at least 20 years or so.

>>63212233
Just do it at the type level.
(make-array 4 :element-type '(integer 0 1) :initial-contents '(1 2 0 1))
If you get a type error, it's true, otherwise it's false! Make sure to document this in the spec.

>>63212451
>being mentally impaired to the point where you actually make that post
Never change, /g/.

>>63212414
The absolute best AI book is Artificial Intelligence by Russell and Norvig of Google fame.

http://web.cecs.pdx.edu/~mperkows/CLASS_479/2017_ZZ_00/02__GOOD_Russel=Norvig=Artificial%20Intelligence%20A%20Modern%20Approach%20(3rd%20Edition).pdf

I'd recommend a physical copy though because it's a nice book to flick through.

>>63212467
'bit is synonym for '(integer 0 1)

>>63212373
You don't need for loops:
new Array(prompt()-0).join().split(',').reduce((a, b, c)=>{ return a + (c+1) }, 0);

>>63212459
> Why?
Those are separate wishes. Learning AI and learning lisp. The question was more like «Is it a good idea to combine them»

>>63212485
Thank you

>>63212508
Yeah, brainfart on my part. Thanks.

Don't be so attached to your code and submit it.

Just look for accepted PRs to see what the maintainer expects, or create an issue to discuss your fix before creating a PR if it's big.

The sad part is, I'm not sure if he's baiting or not. That's how low /g/'s standard is.

>>63207581
The only programming language worth using is Lisp.

>>63212875

And yet, even /g/ can see Rust for what it is.

The first snippet may or may not be correct depending on the context. The second one is incorrect. Why do rustlets always conflate correctness with compiler errors?

How long would it take me to go from "I can make games with an engine and a scripting language" to being able to program well enough to make my own RSS feed reader/Podcatcher? I'm not satisfied with what exists. Don't intend to go pro as a programmer or anything.

It's a valid C++ program, which is incorrect. Same thing goes about JavaScript. Most, if not all Rust programs are valid AND correct.

>>63213017
Where can I learn, then? (I want to use Rust because I like the name and also it apparently pisses off /g/ for some reason.)

The infinite majority or valid Rust programs are incorrect, and the infinite majority of correct programs are not valid Rust. You are simply too mentally deficient to understand this fact.

Why are white people so obsessed with coffees and its 100's of distros?

In c++ say I have two classes. One simple class with a few attributes. Say it's called smartphone with an int for weight, string for name, string for CPU. Another class being an aggregate class of "smartphone" called say motorola.
Inside of Motorola I want to have a vector that houses instances of smartphone. Not just the name but the whole instance.
I can't figure out how to make the vector and how to add smartphone instances to it.
I'd like to output a list of instances of a class and ask which instances the user wants to add to each instance of the smartphone brand.
What should I read to learn how to do this?

>>63213094
>lacking basic understanding of computer science

You literally don't understand what correctness means. Why do you keep using this term?

ppx is actually very nice. It is of course not as good as the macro system of lisps (especially racket), but it is still a very nice asset to have, and the API is very straightforward. I wouldn't call it a hack.

>>63213211
The size is known to the compiler. It's part of the type. The pointer decay only means there exist implicit conversions from array to pointer.

In C, does opening a file with mode wb+ automatically delete all its contents? I don't get it

>>63213308
Yes this mode truncates the file

>>63213322
what can I use if I don't want it to get truncated?

>>63213335
a is for append

>>63213202
how so?

>>63213335
That's r+ I guess however I'm not sure whether it creates the file when it does not exist

Holy shit I never knew even a language can be a botnet. I feel like I dodged a bullet.

I'm looking for some syntactically nice, compiled language. Like crystal, but with a good REPL. Maturity, libraries etc do not matter.
What would you recommend?

What would be the shortest version of FizzBuzz in python? I came up with the basic version
def main():
for i in range(1,101):
if i % 3 == 0 and i % 5 == 0:
print("FizzBuzz")
elif i % 3 == 0:
print("Fizz")
elif i % 5 == 0:
print("Buzz")
else:
print(i)


I feel like I should be able to write this in less lines.

>>63213406
no idea what crystal is like but compiled languages with good repl are
common lisp, sml, maybe ocaml if you are gay

>>63213433
import fizzbuzz as fb

fb.fizz()
fb.buzz()


>>63213433

>>63213433

if you cant do it with just
i%3, i%5 and else
you're trashed

>>63213434
I like both CL and OCaml, but I'm looking for something small and cute like ruby. I'm not looking for some specific features, I just want to play with something warm and fuzzy instead of taming powerful monsters.

>>63213433

>>63213486
OCaml is small and cute. Use OCaml. It does everything, and more.

>>63213497
wat

I'm writing a compiler, and in my bison stage when a flag is set I'm meant to not create a parse tree and just match the input. I'm not sure how to do this nicely with #ifdef. I have tons of this sort of thing:

block : DECLARATIONS declaration_block CODE statement_list
{ $$ = createNode(NOTHING, BLOCK, $2, $4, NULL); }

| CODE statement_list
{ $$ = createNode(NOTHING, BLOCK, $2, NULL, NULL); }
;


Which needs to become:

block : DECLARATIONS declaration_block CODE statement_list
| CODE statement_list
;


But it looks like I can't put the #ifdef outside of the { } because it's in the bison section, not the C section. I tried redefining createNode to be a NOOP but it didn't like that

>>63213497
Holy shit that's nice. Though I'm too brainlet to understand what's happening.

>>63213517
ocaml is bloated as fuck.
>>63213486
sml and scheme are barebones and have no features

>>63213537
the trick is to get the correct slice in the string "FizzBuzz" and if the slice is "" then return a number

>>63213546
If OCaml is bloated, then your only option is to program in C or straight up assembly, and even then C and some ISAs are arguably more bloated than OCaml.

>>63213583

>>63213546
>language X is bloated
This is a paradox of paradigm language design; we desire simple languages, but the useful languages must necessarily have complication to allow the programs written in them to be simple. It's not necessarily a bad thing for a language to be complicated.

>>63213570
what's the deal with the double minus?

>>63213604
I don't work for Jane Street. I like many languages besides OCaml, but I recognise OCaml as being the best out there right now. I'm sorry if you're too much of a blub programmer to understand just how amazing OCaml is.

>>63213626
ocaml is blub language you fucking retard.

>>63213638
No it isn't, you inferior mind.

>>63213661
ocaml doesn't even support macros, you have to use external preprocessor for them.

Indeed, Lisp is the ultimate blub.

>>63213614
because of the modulo 5

8 is the length of "FizzBuzz"

8 - ((-i ** 4) % 5)

with, let's say, 14

8 - ((-14 ** 4) % 5)
8 - (-38416 % 5)
8 - 4
4

without the minus

8 - ((14 ** 4) % 5)
8 - (38416 % 5)
8 - 1
7 # bad length, it shall be a length of 4 (fizz or buzz), or a length of 8 (fizzbuzz) or length of 0 ("" -> return a number)

Serves you right.

Reminder that R5RS is 50 pages, the C11 standard is about 700 pages, and the C++17 standard is about 1600 pages.

>>63213969
>5RS is 50 pages, the C11 standard is about 700 pages, and the C++17 standard is about 1600 pages
The Brainfuck standard is less than one page, making it the superior language.

>>63213969
r5rs doesn't define working language.
The implementation still has to provide threading stuff, modules, sockets, directory and file handling...

>>63213969
Reminder that the Common Lisp standard from 1994 defines more symbols than C++14.

>>63213996
C++ does not have symbols it has keywords. The CL grammar uses 0 keywords.

I assume you're from a country where the right-wing is very liberal? In the United States, it would be the exact opposite.

I mean, both of the primary parties in the US are about the same, but generally speaking one party's voters are for free speech over the other.

>>63214047
It's another ~80 keywords in C++14: http://en.cppreference.com/w/cpp/keyword , still less than ~1000 symbols in CL.

I don't care to have these retarded dictionary arguments.

When self-proclaimed right-wingers talk about those things, they're talking about freedom from government meddling and from left-winger opinions being enforced on them.
