Do you need to learn Java before learning Scala?

>>60269008
From that family, C++ is a far better match with all the inconsistent, poorly thought out crap it has bolted onto it.

Java langs are a complex hierarchy.

You need to start Javascript so you can understand the foundations of Java. Then Java. From there you need to learn Clojure so that when you dive in to Scala you understand its scopes and methods.

>>60269033
It would be a good idea, in case you want to interact with or utilize java components in your application.

There's a lot of well tested solutions and java libraries out there, so it's worth reducing any language friction up front.

I feel like there's some way to optimize that snippet on OP's pic.

Oh you silly Billy.

>>60269041

>>60269055

>>60269008
C is an objectively decent languages for its domain.

I like R because I can quickly analyze massive data sets I work with, but it takes me like fucking 10 minutes to upload like 3.5gb of data, so I think I am going to start full time using python....but ggplot2 is amazing for presenting data and at the office im "that guy who makes amazing pitchbooks/graphs" so idk, fuck


Also when I run monte carlo sims I have to leave programs running overnight just to get enough data to be able to meaningfully analyze a hypothesis

I KNOW it can be done faster in "lower level" languages, but I never learned comp sci (math major) so I cant just pick up C and write what I am doing in it

Error codes are great. If your language has features to make it easy to handle them, like Rust's try! or Haskell's Either (or MonadError, or whatever).

How much code does Reddit keep private from the public Github repo?

I've been looking through the code to see if there are any methods for checking one user using multiple accounts to vote on posts and don't see any methods for accomplishing that info directly.

There's some stuff for checking what IPs are accessing accounts with a comment about "send this info so we can investigate". They can't be doing vote manipulation checking by hand? Or do they keep their vote manipulation checks private

You can learn Python and then use C and C++ binding for the parts where you require speed.

>>60269503
Wanting to learn python is like wanting to learn how to read. There are resources everywhere. Because of how easy the language is, every resource is technically good enough.

I've been going to Uni for a couple months now, hide all prior knowledge!

It's taken me a while to grasp but 99% off the people in CompSci come in with no prior knowledge, they just expect to learn all this stuff when they get there.
I've finally managed to make some good mates but they get quite and defensive whenever I whip out previous projects. They will be thankful when they realise they can come to you for help with their work though.

Also the professors there are pretty thick, most of them are working with severely outdated limited knowledge, they do not care about their fields 90% of the time, I know it's a """place of learning""" so you'd expect them to care but they don't.

Don't make the same mistakes I did, these people are massive casuals in disguise!

You can string a bunch of single-letter arguments together like so:

C makes no guarantees for TCO, but every decent C compiler implements it anyways. Incidentally, clang and rust use the same code generator (LLVM), so Rust gets TCO wherever the equivalent code in C would when using Clang.

i'm almost finished this assignment for my c++ course, but the very last part is triggering me

i have a function that takes in a string like "1+2*(5/3) + 5" and i need to tokenize it and return it as a vector of strings

stackoverflow is giving me lots of useful suggestions but they all use a whitespace delimiter, which my string may or may not have

my current plan is to just read in the string by index and seperate every character with a whitespace and then tokenize it with a str stream, but that sounds like a completely retarded way of doing it

any suggestions?

if you're a math major have you thought of trying a lisp language? i've tried a lot of different languages but among them it's pretty unique and was designed with math theory(lambda calculus) in mind, so if you find something like c difficult it might be worth a shot. it's pretty freely expressive with lots of room for abstraction, instead of having to deal with someone's arbitrary typing and/or syntax rules and whatnot.

>>60269503

There are certain properties that your PDF must have to guarantee good convergence. Also depending on the problem you're looking at you could make up weighting functions that pick out MC samples that best suit the purpose. For example if I want to calculate expectation values of a many-body quantum system I could use DMRG to truncate the Hilbert space so that I don't need to integrate over such a large parameter space with QMC.

bool getConfirmed()
{
  try {
    return confirmed;
  } finally {
    if(confirmed) confirmed = false;
  }
}

for all i can tell java and c# are so similar(not considering libraries, which should probably be the key factor in your decision) it almost doesn't matter. just learn both, or use whichever one you need. for what it's worth, at the moment java is more taught in schools and probably more used in businesses.

if you're into games and stuff you might consider prioritizing c# though, for example if you've ever considered getting into something like unity development then c# is the obvious choice.

that being said i hate c# and java, and wouldn't use them if i didn't have to myself.

>>60269403
That's the difference between error code and error types: error types are cleanly handled via e.g. rust's ? or pattern matching, etc. Error codes cannot be: they imply that you have a separate channel for the return value and for the error code and the error code is almost always ignored because it's too much trouble to actually deal with it correctly.

How difficult would it be to create a red button that when pressed, starts a song. So far I know javaScript and HTML. Would CSS be necessary? This would be my first actual project.

>doesn't know CSS
If you're learning HTML, you pretty much need to know CSS. CSS contains all the formatting rules for how your HTML is displayed. HTML is the arrangement of pots and plates on your shelves, CSS is the collection of aspects of said objects and shelves like the color and size.

>how difficult would it be to create a red button when pressed, starts a song
Uh, really fucking easy. Like maybe 6 lines of jquery code and an html button.

No dumb cunt, there will also be people there who make you look like a kid.

I came into first year at 18 years old, having completed 2 units alongside HS through some Ausfag meme with 2 near perfect internal study scores (99), I was in the process of writing a GBC emulator and had about 10 languages confidently under my belt as well as a phat portfolio of hardware and software projects I'd built over my limited life. I thought I was top shit.

One of the first dudes I met there was a 18 y/o second year who was already working at the Uni in their research department doing some shit with analysing pulsar data from space, with his entire CS degree under his belt through the same Ausfag meme I used, and was in the process of annihilating his math+physics double degree.

I got a rectangle to move across a window. I feel extremely accomplished right now.

>>60272112
>he doesn't post a webm of this momentous occasion
Seems like you don't feel accomplished enough.

So, i'm making a MIPS simulator on C (uni work, I know it's useless) and I'm having a bit of problem. While trying to load the following bin file:

0020 0820 2020 0920 0000 298d 0400 0224
2420 0420 0c00 0000 0900 2011 0100 0224
0000 048d 0c00 0000 0400 0224 4b20 0420
0c00 0000 0400 0821 ffff 2921 0600 0008
0a00 0224 0c00 0000 

I tried using fread (&mem[i], 4, 1, fprog); to read

where mem is a int32_t type, and fprog is the file pointer to the bin file. Thing is, it misreads it. By simply using a printf to see what's read, this is the result:

20082000
20092020
8d290000
24020004
20042024
c
11200009

8d040000
c

2004204b
c
21080004
2129ffff
8000006
2402000a
c
(and all else is zeroes)

I have no clue what I'm doing wrong. i tried changing mem to uint32_t instead, and the same shit still happens. Can anyone in here please shed a light on what I'm doing wrong? File is open as "rb" btw.

Well understood standards are usually better than rolling your own shit for a number of reasons.
You get more library support, time-tested techniques.
But maybe rolling your own is necessary if the system isn't powerful enough to support HTTP (which has a lot of bloat & metadata that might push shitty microcontrollers over the edge, but I don't work in medical engineering so I'm just guessing here)

It doesn't really matter all that much, to be honest. It's an annoyance if you're expecting it to be one way and it's another, but anyone with at least a double-digit IQ should be able to handle it just fine. There's no performance impact.
Also, Stroustrup literally wrote the language, so he kind of gets to set the rules.

so if you really need the 32 bits you should use long to be safe.

>>60274394
Not exactly.
usual int32 cover
-2147483648 to 2147483647
but the standard only state that long int cover
-2147483647 to 2147483647

You don't know if -2147483648 is a long int

>>60274479
>Not exactly.
No it does actually specify things in terms of bits.
However, it allows for sign & magnitude, ones compliment and twos compliment implementations to exist.

>>60274495
OK I get it, you and I were not talking about the same thing when saying 32 bits.

Sorry

How the hell does this work? REE, I have been failing to do SICP exercises 3.23 for hours because of stupid shit like this. The concept behind the question is easy (double sided queues).

(define x (cons 1 2))
(define r (cons 1 0))
(set-car! r x)
(set-cdr! r x)
r = ((1 . 2) 1 . 2)
(set! x 0)
r = ((1 . 2) 1 . 2)

I would have expected r = (0 0)

And also

(define x (cons 1 2))
(define r (cons 1 0))
(set-car! r x)
(set-cdr! r (car r))
r = ((1 . 2) 1 . 2)
(set! x 0)
r = ((1 . 2) 1 . 2)
(set-car! r 0)
r = (0 1 . 2)

I would have expected r = (0 0) when x changed to 0. And eve after that, I would have expected r = (0 0).

If you looked at the current standard, they have extra comments there.
They talk about bits directly in the section about <stdint.h>, although those obviously aren't the standard types.

What's the deal with this in scheme? Why does using set! on a null value bring an error while using set-car! doesn't?

(define x (cons '() 1))

(set! (car x) 2)

;Variable required in this context: (car x)

(set-car! x 2)
;Unspecified return value

x = (2 . 1)

>>60274576
Those one's complement minimum values of signed types are disgusting.

>>60274677
C supports ones complement systems though, so they kind of have to do that.

>>60274684
I know but it's still disgusting.

>>60274677
why?

>>60274732
because of the whole -0 bullshit one's compliment brings with it I presume.

>>60274753
there's only one value for 0, 0
127 is 127
128 is -127
129 is -126
255 is -1

>>60273545

In sepples you can do

Foo *bar, *baz;
bar == baz; // compare identity/location
*bar == *baz // compare equality/value

Overloading == in Java wouldn't be overloading, it would be overriding. It'd actually be pretty awful for readers, since they no longer know if they're comparing the references or the objects' logical values.

>>60274775
>128 is -127
it's -128

>>60268718
The function should be called getAndClearConfirmed

>>60274775
That's two's compliment anon.
Better read up on your basics :^)

>>60274753
C says that (for integers) the only way to make a negative zero (for implementations that support them) is to use bitwise operations or using another negative zero.

I'm working on implementing sorts, if I'm sorting a list in ascending order but I want all 0's to be placed at the end of the list how would I go about this?

>>60274970
Just have zero compare "greater than" everything in your sorting function, and they will turn up at the end.

I'm trying to cut out the individual panels of a comic strip, I've already detected the panels themselves using openCV but how do i go about cutting them out?

These people are overpaid to sit there and write basic functions, they aren't even good writers. Who else has seen this (and where?)

not him but like this? this is a bubble sort.

>>60275057
Pretty much.

>>60274559
>(se!t x 0)
The variable is a mutable cell in itself. You are making x point to 0, you aren't magically transforming the cons cell into an integer. That never happens in Scheme. Scrap your whole code off and try again.

>>60274582
Because set! doesn't support that. It's just for setting variables, nothing more.
