You may want to keep track of the line number and check if it's odd or even. If it's even, then you have a grade and you can do something likedouble average;
average << atoi(line.c_str());

Fizzbuzz part 2:
From 1 to 100:
If a number is evenly divisible by 3, print Fizz.
If a number is evenly divisible by 5, print Buzz.
If a number is evenly divisible by 7, print Baz.
If a number is evenly divisible by 8, print Norf.
If a number satisfies more than 1 of these rules, concatenate them
i.e. 15 says FizzBuzz, 24 says FizzNorf

I understand SQLite being slow, but I didn't think it would be that slow. Apparently there are some tricks to really speed that shit up: http://stackoverflow.com/questions/1711631/improve-insert-per-second-performance-of-sqlite. I'll look into that when all the must haves have been implemented.
I'm not really into databases, but AFAIK PostgreSQL performs better than MariaDB/MySQL. The only reason MySQL is so popular, is because of muh LAMP stack.

>>53645144
this still uses a 5th comparison, any way to do this with only 4 comparisons AND string concatenation ?
>>53644846
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?
Actually benefits. No academic reasoning. Immutability implies a need for more memory, and "easier to reason about" still means absolutely fuck all, when you're trying to find an argument error in a 8+ function callstack.

>>53645297
>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The way people talked about OOP in the early 90s, functional programming was an outdated and failed meme.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

>>53646281
>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
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.
>>53646337
I don't know about that.

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. I'm also trying to work on a command line email client, but that's not going very well either. I'm having a hard time getting into the GMail API (I need to figure out how to "agnostically" access it, like with just OAuth and the standard Python imap/smtp libraries).
My life is hell.
>>53646430
Yes, but you need some way to know that the storage is safe to reclaim in the first place. God forbid you suggest using a garbage collector for that.
>>53646440
>I spent two days getting reddit set up on a server
That's definitely a bad sign. It should take an hour tops. (unless it has changed dramatically since the last time I contributed.)

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

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.

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';

>you'd still have to remove the vowels somehow
remove them normally?
>for i in string
the string is a reference to data that is kept immutable during the for operation.
>string.remove
you are updating the reference string to point to new data that is the previous data updated.
At the end of the operation the 'string' data used in the for loop is not referenced by any variable and it collected.
Additionally, you can make string.removes mutable if there is only one reference to the data pointed to by 'string'.
Immutability is possible and unless you do something particularly stupid, not a performance drain in a well designed language.

Basically I have another program feeding this program various input cases, and it calls my program to do the computation with those inputs and test for correctness on the output (thats how they test if our code works correctly).
Whenever I delete lines 2-4 it gives me an error saying I need a mainpublic class AccessList {
public static String access(int[] rights, int minPermission){
String s = "";
if (rights.length == 0){
return s;
} else if (rights.length > 0) {
for (int i=0; i<rights.length; i++){
if(rights[i]<minPermission){
s= s+"D";
} else {
s=s+"A";
}
}
}
return s;
}
}
I can't get this fucking shit to compile

if you're trying to run AccessList.java you need a main
if you're running SomethingElse.java which uses AccessList you need a main in SomethingElse.java but not in AccessList.java
i'm looking at this and i'm a little confused. is it assuming that the solution for every length is already solved before you do anything?
package DynamicProgramming;
public class RodCutting {
public static int profitDP(int[] value, int length) {
int[] solution = new int[length + 1];
solution[0] = 0;
for (int i = 1; i <= length; i++) {
int max = -1;
for (int j = 0; j < i; j++) {
max = Math.max(max, value[j] + solution[i - (j + 1)]);
solution[i] = max;
}
}
return solution[length];
}
public static void main(String[] args) {
int[] value = { 2, 3, 7, 8, 9 };
int len = 5;
System.out.println("Max profit for length is " + len + ":"
+ profitDP(value, len));
}
}
>>53648905
Oh - you're trying to call it from another process?
I think I understand now. Put those lines back in. You will need to get the input parameters from the args variable, which is an array of the strings passed to the program on the command line.
For example, if you runjava AccessList a b c
Then args will contain "a", "b", and "c".
>>53644412
This is a fucking good book
>>53644813
Should be called the right way.
>>53648969
Okay, I need a main. How do I correct the code to take any input and then produce the output? What I have now is testing a specific parameter.
This shit compiles but it's on a specific input.public class AccessList {
public static void main(String[] args){
System.out.println(mayAccess(new int[] {},20));
}
public static String mayAccess(int[] rights, int minPermission){
String s = "";
if (rights.length == 0){
return s;
} else if (rights.length > 0) {
for (int i=0; i<rights.length; i++){
if(rights[i]<minPermission){
s= s+"D";
} else {
s=s+"A";
}
}
}
return s;
}
}
I want something more general to allow the tester to feed it input.
something likepublic class AccessList {
public String mayAccess(int[] rights, int minPermission) {
// fill in code here
}
}
But I don't know what to do and it's pissing me off. This is one of my first java programs.
>>53648984
No, it's shit.
>>53648969
Actually I don't think I need a main here. So how do I re-write the code?

Kill yourself. C99 and C11 (especially C99) add shitloads of nice features that makes the language MUCH nicer to write in, while still being true to the "C spirit".#include <stdio.h>
int main()
{
int a;
puts("Hello World!");
int b;
}
>That code is invalid C89
>>53649078
Either they're just placeholders for angles like the thetas/phis or they're defined elsewhere in the paper. Omega looks to be the incoming/outgoing light directions.
>>53649111
so what's actually inside the solution array? is it just the value of the maximum profit for a given length of rod, or does it actually tell you how to chop it up? the website i got this from doesn't say http://algorithms.tutorialhorizon.com/dynamic-programming-rod-cutting-problem/
>>53649130
seriously?? since when
>>53649168
This week, don't know which day exactly.
>>53649160
Moreover, they add restricted pointers which helping compilers with vectorization. Although C99 adds it, I think C11 makes it standard
>>53649162
i figured out what they meant. instead of using dot(N,V) and dot(N,L) they use H=normalize(V+L) and dot(N,H)
this is some pretty deep shit if you're no good at math but i find it interesting and useful
>>53649160
What exactly is invalid about this?
>>53649234
All declarations MUST appear at the top of a block in C89.
>>53649130
>>53649198
https://api.4chan.org/boards.json suggests otherwise
>>53649275
well we're only on page 4 at 330, page 2 at 320
>>53649275
Clear your cache.
>>53649249
well yeah, why would you declare a variable without using it?
>>53649295
So? /g/ isn't ridiculously fast, so threads won't be pushed down the board that quickly.
>>53649320
My example was contrived. There are lots of situations where you want to declare variables after you've already run some code. Also, it makes sense to declare variables where they're needed, not front-loading all of it.

So I had a workmate that use to write the worse code that I and my other workmates ever seen. He had no ideia about what he was doing. But he thought he knows more than anyone.
If you are going to learn by yourself, please learn the base. Don't just get some way to get it done. Learn and understand what you are doing.

It's alright, I think it helped me understand the basics in the first 7 chapters but after that you kind of need to start reaching out on your own and supplementing. If anything the programming questions always give me something to do, my biggest issue was finding some work I could do to implement what I'm learning and this book does that.

I suggest you to keep yourself more about to deep learn OOP than Java.
Java is a great language to program OOP.
But if you don't really understand it, you might end making a shit code.

Any book recommendations for this? I am sticking to Java since I probably know it the most out of any other language.
