Took me a second to work out what the fuck you meant by evenly divisible (could have meant is the result of division even).
>>53645070
The only advantage to using a switch is if you want to drop down into other cases without breaking, but there's no point because you'd need to check conditions again anyway.
Given the number of permutations, it's most efficient to just check each of the 4 modulo results.
What are the benefits of functional programming?

>but is it really more efficient than something as simple as >>53645144
no
>>53645194
Absolutely none. Mainstream functional languages (like Haskell) tend to use less code for certain tasks than mainstream OOP languages (like Java). That's about it.
They're not comparing the functional paradigm, just the implementations of certain languages.
The way people talked about OOP in the early 90s, functional programming was an outdated and failed meme. OOP subsumed functional programming: pure functions are just one kind of object. Then Java came along and the functional programming community pretended it's the epitome of OOP. Java explicitly avoided things like multiple inheritance. How can it be the epitome of OOP if some things aren't even objects?
In the past, they would compare their language to C. Not even C++ or Ada, plain C (before C89, too). Some parts of their language are worse than a language that was called "portable assembly" since the 70s. What an accomplishment!

Functional programming is pretty shit for systems programming (where verification is actually really useful) without linear types, I'll concede that much. And given that there's only a few properly linearly-typed languages out there, and they're all academic wankery, it probably looks pretty bad to anyone who isn't more interested in the development of languages rather than the usage of languages.
>>53645973
I am, I try to be!
>>53645986
Systems programming is all about access to particular memory addresses for memory management and hardware devices. The important part is the specific addresses, not the fact that they are accessed once (presumably to remove the need for GC). There's no reason why an operating system can't have a GC once the memory management parts are implemented. There were OSes with GC in the 70s and some OSes like Singularity depend on GC for all programs as part of the security model.
>>53645986
>linearly-typed languages
What's that?
>>53644846
I know, I've "optimized" the string concatenation but not the amount of checks, it's very clean like this though.
I've been posting my progress on a spacey crafting game. I'm using webgl which g seems to have a bit of apprehension for. Anyway, I'm working on some positional lighting code which I don't understand very well, so I'm creating some tools to help me debug the situation. I've made the classic mistake of copy and pasting code but not actually making sure I completely understand it, so I'm going through it all line by line to learn exactly what everything is for. The attached video is a basic cube with axis placeholders so I can still see my objects positions if my lighting code blows prick. This is just test code, so now I have to go back into my engine and create a shader manager so I can switch shaders from the ones that draw those simple lines to the dysfunctional lighting shader.
If you think you can't do much with webgl check out this site:
http://goocreate.com/gallery
That site has a lot of interesting programs people have made from the goo webgl engine. My guess is a lot of you haven't looked at webgl since the early days and imHo you should take another look at it. If you have the time, sign up and create a new project out of the spaceship demo.
To be honest, whether the opengl "window" is attached to your browser or a gui window shouldn't really matter, and I know the real issue is that the code is running in the browser which is going to be much slower than native code, but I still think it's neat.
If you guys want me to post my code somewhere let me know. Does github offer free public repos?
>>53646150
Linearity with regard to memory management doesn't mean you only get to access memory once and then it's thrown away (although that could be the semantics if you really wanted...), it's that you can make types that ensure that there's exactly one point at any given time where a piece of memory can be mutated OR many points where it can only be read.
And I understand that certain forms of garbage collection like regions can be faster than allocating and freeing everything individually, but they're not suitable for all use cases. And even if an OS has a GC available for software to use, it's not part of the language used to write it. To write an OS you need something with little to no runtime - something with a good GC built in won't fit the bill. And of course for real-time software you don't want a built in GC either.
>>53646215
If a variable has a linear type, it must be used exactly once. Kind of like noncopyable objects in C++ or Rust, but those are uniqueness (affine) types which means that they can be used 0 or 1 times. Linearity is good for modeling effects and especially for memory management, like monads, but it's more primitive and generally more flexible.
This is a good paper on the subject:
http://homepages.inf.ed.ac.uk/wadler/papers/linear/linear.ps.gz

Those are useless when writing an OS.
>>53646307
Yes, I did, but I didn't really understand it, I had just copied the code.
>>53646336
Yeah, uniqueness types are a bit weaker though because you can implicitly "drop" a unique variable.

You don't use it and it's destructed. Fine in most cases for issues of memory management and ownership, but certainly not for modeling effects (you don't want to drop the world!) or what are called "borrowed references" in Rust (they're truly linear while objects are only affine).
>>53646367
>I don't know about that.
>In the linear system, each operation that introduces (and allocates) a value is paired with exactly one operation that eliminates (and deallocates) that value.
>Hence, after an application the storage occupied by the function may be reclaimed, and after a case analysis the storage occupied by the node analysed may be reclaimed. No reference counting or garbage collection is required.
There is no storage to be "reclaimed" in an OS. There are just addresses in a finite state machine. All of the storage already exists.
I spent two days getting reddit set up on a server (it would've been way easier if I wasn't such a retard), thinking I could jump into the source code, make a bunch of contributions and become a super programmer, but now that I have it working, I'm stuck. My laziness is kicking in again, and I'm not quite sure what the fuck to do.
I want to be able to get a programming job by the middle of the year, but I'm stuck in this mediocre gross NEET purgatory.

Do any of you guys code for a living without a degree? Just wondering if it's possible. I don't care if I won't get paid much--I just want to get a foot in the door and earn a livable wage and go to school later on.

No, but I had an internship at a coding company a while ago and I can confirm that you don't necessarily need a degree if you're good. Met quite a few people who didn't have one.
greetings senpaitachi, I was logged into the ol' 4chan yesterday and I posted some code and asked for a critique and some nice anon posted his superior implementation.
Prompt:You are given a string s composed of letters and numbers, which was compressed with some algorithm. Every letter in s is followed by a number (possibly with leading zeros), which represents the number of times this letter occurs consecutively. For example, "aaaaaaaabbbbbbcc" would be given as "a8b6c2".
Decompress s, sort its letters and return the kth (1-based) letter of the obtained string.
Here's my code:def Expand_It(s, k):
import re
length = 0
count = 0
s = filter(None, (re.split('(\d+)', s))) # parse s, store as list, remove empty strings with filter
t = {}
for i in range(0, len(s), 2): # consolidate s into dict, {letter:count}
if s[i] not in t:
t[s[i]] = int(s[i+1])
else:
t[s[i]] += int(s[i+1])
for key in sorted(t):
length += t[key] # calculate total decompressed length
if count < k:
count += int(t[key])
letter = key # keep track of letter at position 'k'
else:
break
if k > length:
return -1
else:
return letter
Here's his implementation:import re
from collections import defaultdict
def decompress(s, k):
partsList = re.split('(\d+)', s)
#print partsList
letters = defaultdict(int)
for letter, number in zip(partsList[::2], partsList[1::2]):
letters[letter] += int(number)
result = ''
for letter in sorted(letters.keys()):
result += letter * letters[letter]
#print result
return result[k-1]
basically, I wrote my implementation the way that I did because that is the limit of my knowledge right now. Can anyone explain what's going on in anon's implementation for me, tell me what I should look up/learn, etc.? I'd appreciate it

Other day I was trying to finding a software for joining images so I could post a series of screenshots as only one image, but I couldn't find any. Then, I making my own. Is there demand for that or it's something seldom people use? If there is, I could post it on the store.

Come on, Anon. I can keep a secret. You don't need to go into detail.
>>53646660import re #import regex
s = "a2b3c2a1" #here be a string
r = "" #holder thing
i = 6 #Target index
l = re.split('(\d+)', s) #split string into list
l.pop() #there'll be a blank at the end, remove that
for i in range(0, len(l), 2): #increment by 2
for j in range(0, int(l[i+1])): #Repeat operation by number of times specified in string
r += l[i] #add letters to result
r = ''.join(sorted(r)) #Sort that shit and smash it all together
print(r[i-1]) #print result
This is a similar version with comments. In his version anon is basically using a dict instead of sorting.

I think garbage collection in OSes is the future. Desktop OSes already have enough things that aren't real-time that they might as well have GC.
Intel, Xerox, Symbolics, Bell Labs, and Microsoft (still experimental) have all built computers or OSes that use a GC, and garbage collected languages like Smalltalk, Java, Haskell, Oberon, Cedar, Algol 68, and Lisp each had at least a couple OSes.

Linear types enable the guarantees of GC without the overhead.
The core problem is: how do we prevent unreachable leaked memory, and how do we prevent dangling pointers from being used?
A GC modifies the run time semantics to make the concept of a dangling pointer or truly unreachable (from the GC's perspective) memory absurdity.
Linear types modify the type checker to make the program not compile if it's not provably respecting these laws.
I don't know about you, but I'd rather my OS doesn't fritter away all of my hardware resources.

std::thread is typically using pthreads under the hood. Even on Windows with MinGW-w64, winpthreads is used.
In python 3 how do I check for duplicates?

there are two distributions of MinGW-w64, one that uses pthread and one that uses winapi.
>>53647675
you could automatically avoid duplicates by using a set objectIn [1]: set([1, 1, 2, 1, 3, 2, 3, 4, 4])
Out[1]: {1, 2, 3, 4}
>>53647936
I'm seriously depressed every single time I see you post because I realize you still haven't offed yourself. My birthday is coming up in August, do me this solid.
>>53647936
And I'm pretty sure winpthreads is using the WinAPI behind the scenes.
>>53647936
For my program I need to have the user enter a list, then the program has to spit back the list with all the duplicates removed. When I use set it gives everything in a jumbled order
>>53647884
Turns out the sequence I was studying he had already characterized.
>>53647936
>you could automatically avoid duplicates by using a set object
>>53647675
Alternatively, if you simply want to detect them:
all(map(lambda x: x > 1, collections.Counter(seq).values()))
>>53647983set(list).sort()
>>53647986
hurrrrr, I'm dumbmax(Counter(seq).values()) > 1
>>53648002
He probably means he wants to remove duplicates, and preserve order. Probably remove all but the first occurence.
>>53648044
yeah that's what I mean

sorry bud, using prefab libraries and built in meme functions is all python ""should"" be used for
>>53647675import doyourownhomeworkfag
>>53648055
Well think about it. Iterate through the list and if a value has been encountered before, remove it. Or doesn't that make sense?
>>53644961
None. Always use versioned python command, so either python2 or python3. Don't assume that default python implementation on any computer is the same you use.

yes, you can't bypass winapi on windows since microsoft never documented the system calls.
>>53647983
>>53648044
set(list) preserves the order and a set object doesn't have a sorting operation. if you want a sorted set, you must pass a already sorted list.l.sort() # in place
foo = set(l)

Trying to make a REST API in node.js using express and mongodb (mongoose ORM), to make a task planner. After that, use React to create a front-end for it and maybe react native to make an Android app.
It was tough making the switch from PHP, but I'm glad I did it. PHP feels very oldschool now.
Does anyone have a good tutorial on how to use React? Preferably how to integrate it with a REST interface.

Can someone help me get my code to compile whenever I delete System.out.println(....) in the below code?
public class AccessList {
public static void main(String[] args) {
System.out.println(access(new int[] {},20));
}
public static String access(int[] rights, int minPermission){
String s = "";
if (rights.length == 0){

if(rights[i]<minPermission){
s= s+"D";
} else {
s=s+"A";
}
}
}
return s;
}
}
That compiles ^ but whenever I try to remove system.out.println it gets fuzzy and I have no idea what to do.
I want to get this code to compile:
public class AccessList {

} else if (rights.length > 0) {
for (int i=0; i<rights.length; i++){

} else {
s=s+"A";

Seems that the situation is more of an issue of mutable objects being shitty instead of Python's for being a bad idea.
If someone could make Python, that isn't slow as shit, with immutable objects, stackful generators and a nice (dynamic) type system it would be one of the most perfect languages to work in.

Kik told him to rename his package. He said no.
They went to NPM. NPM then took ownership of the package and renamed it.
The developer was rightly pissed, and pulled all his packages from NPM. Then NPM decided to put them back because he'd pulled their pants down.
Basically NPM are corporate dick suckers. Also Kik is fucking shit and has ruined Omegle.
I'm trying to make a program in C that will run through a text file and copy each word and and a "1" to the end of it. There's only one word per line, this is for editing a word-list. I could use the sed command, but i'd like to do it using C. I think I'm close because the code I have reads the first word in the file then adds a "1" to the end and quits after that, and I cannot figure out why. Can anyone help point me in the right direction? Below is the code for what I've got so far... It's supposed to read until the end of the file, but stops after the first newline (10).#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main() {
FILE *fHandle;
char filename[64];
char newString[64];
int ch;
printf("Enter file name: ");
scanf("%s", filename);
fHandle = fopen(filename, "a+");
if(!fHandle) {
printf("Failed to open < %s >!\n", filename);
exit(0);
}
while((ch = fgetc(fHandle)) != EOF) {
if(ch != 10) {
newString[x] = ch;
x++;
} else {
newString[x] = '1';
newString[x + 1] = '\0';
fprintf(fHandle,"%s\n", newString);
x = 0;
}
}
fclose(fHandle);
puts("Operation Complete");
return(0);
}
