What are you working on, /g/?
a=1 b=2 c=3 d=sentence with spaces
Trying to create a regular expression that can parse that.
The keys never have spaces, but the values might.
I didn't think it would be that hard to make an expression that worked, since it boils down to:
>get the word before the =, and get everything after up to and not including a word proceeded by an =
but I can get anything that comes even close to doing that
>>53966582([^=]+)=([^=]+)
Or similar.
>>53966688
Oh fuck. Just woke up. That's not gonna work.
>>53966582
Regexp is greedy, you can't program "just leave out one". You'll need to you a more general parsing algorithm like PEG or just fix up the output to what I wrote.
>Tfw no gf who programs exclusively in Java
>>53966582
write a tokenizer instead

defaultBackgroundColor = "#FFFFF2";
}
Is this bad design?
When you're choosing a high level language, why would you choose Python if it's so slow?
>>53966760
Duh?
>>53966582
>a=1 b=2 c=3 d=sentence with spaces
Couldn't you simplify by requiring sentences with spaces to be enclosed in quotation marks? That would make a pretty easy regex.
I've never seen that not being a requirement (except possibly if it is the last argument)
>>53966760
Why are you surrounding the assignment in a static block?
>>53966773
Java doesn't have the abstraction of Python and if I decide Python is sufficient it's because the speed of the program doesn't matter. There's no reason to write scripts in Java.

Depends what you want to do really.
Python has many great applications.
How do I figure out if a point lies on a polygon's edge.
I can figure out if it's inside or outside of the polygon but not if it's on the edge.
Everything is in integer coordinate so I'm finding it hard to figure out.
I implemeneted the polygon as a list of 2D vertices and a list of edges.
The edge object has it's starting point, ending point, and the a, b, c parameters that define the line it lies on.class Edge
{
int a, b, c;
Vertex start;
Vertex end;
}
My first idea was to just check if for the vertex it holds true thata*v.X + b*v.Y + c = 0
for some edge and that vertex lies within the polygon
But it doesn't really work.
>>53966779
Not my standard that I have to parse, it's from a yEnc encoded output.
I'm not sure why quotations aren't part of the standard, but you're right, it's only spaced if it's the last argument.
In c++ if there are 2 libraries with same macro that causes error in when compiling how should I go on about getting around it?
Is it even possible?

>>53967735
I implemented the distance check the anon posted (the squared one)
It works but only for straight edges (lines parallell with x or y axis)
It might be because i'm doing this interactively.
The user draws a polygon then clicks around and every point that is clicked is checked to see where it lies.
Maybe this is hard because it's pretty tough to pinpoint the exact pixel of the line and it's even harder when the lines are slanted because bresenham's algorithm does some inherent rounding.
What is the most "fun" programming language?

>>53967802
integer coordinates will fail unless coordinates are exactly integer and on the line, which will be false for most of the time.
>>53967833
Yeah thought as much. That's probably why all the algorithms I searched for online only make calculations if the point is within or outside the polygon.
I guess I could add some kind of buffer zone, if it's like... within 3 pixel distance of the edge and qualifies as within the polygon then the point is close enough to the edge to be qualified as on th edge.

>mfw I was accidentally setting up identical vertex attribute streams almost 400 times per frame
>>53967938
>a better/easier way would be just marking edge points while drawing the polygon
The edges are marked it's just that drawing the edges relies on bresenham's line algorithm and that algorithm does some inherent rounding, it colors points that mathematically should not be on the line if the line isn't vertical or horizontal.
>>53966773
Because writing stuff in python is easier and faster when you can just stuff objects inside tuples and lists and do all sorts of shit with that.
What do you do in Java when you want to return two objects of different types at once? You gotta waste time writing a wrapper class.
If your goal is top performance you should probably use C++.
>>53968006
you could store the pixels and just look up the color of the pixel that corresponds to the point. but that could take too much memory if you need to keep track of many lines individually

This is just awesome. You don't need to make a million small programs to offline shit anymore. You can just put it in there.

>>53968091
Yeah but theoretically if the polygon has a million edges then you have to make a million calls to check on which edge the point lies in the worst case scenario.
But yeah I left it in because it's really short and simple to understand but I still have the issue of it not working for slanted lines.
I don't give a shit at this point, the use case for this is practically non existant anway.

>>53968798
Yes, that's the basic principle. But in practice you'll need more complicated tests to catch memory errors. Simply storing an increasing integer isn't enough. You need all sorts of patterns (101010..., 11001100, etc.) that you roll, invert, shift, etc. in various ways and compare the results.

dude you might pull it off but you have a serious risk of getting blacklisted if you apply to companies without knowing fuck all
>>53969217
Because an increasing integer won't test all possible bit patterns. You have to systematically test them all (or nearly all) to catch errors.
I'm no hardware expert, but I'd imagine some errors prop up only when adjacent cells store certain patterns, so an integer that only uses 8 bits isn't enough, you need a "bigger" pattern to test cells from a wider area.

I had no sex drive before taking hormones but now it's impossible to focus on programming for long periods of time without wanting to masturbate. not having a refractory period doesn't help either...

>Where is my mistake?
I do not understand what your intentions are with that code. You algorithm makes no sense when compared to the problem statement.
I can think of two obvious ways to do this. One is the naive method, in which you start with some number, check to see if the remainder for all numbers 1-20 is zero, and if it isn't, increment it and check again until you find a number that can be divided evenly for all numbers 1 through 20.
The other method is to factor all numbers, 1 - 20 down to primes, stack/sort out duplicates, and multiply to compute the number directly.

You should always mark variables volatile.
>>53970248
I was doing the 'naive way' except that I added always 20, because anything else would be dumb.
Found my mistake. If my number would have been divisible by 1 to 20 then 20 would get added up anyways at the end. So I just had to move the incrementation.#include <stdio.h>
const int div = 20;
int main() {
int isDivisible = 0;
int num = 20;
int i;
while(!isDivisible) {
for(i = div; i > 0; --i) {
if(num%i == 0) {
isDivisible = 1;
} else {
isDivisible = 0;
num += div;
break;
}
}
}
printf("num: %d\n", num);
}
>>53970360
No, you shouldn't, let the compiler optimized out variables you don't actually need. And I don't see why the compiler would optimize out that variable.
Why should I make it volatile?

>>53970417
Any more context?
I have a list of coordinates (x,y). I need to iterate it so that for every iteration I get to substract x(i+1) - x(i-1); so for 4 elements in the table the first one is x(2) - x(4). Problem is I don't know how many coordinates I'm going to have in the table.
So basically I need some list that loops around. I'm coding in Java. Is there a neat data structure that will let me do this?
>>53970406
Big deal. My school didn't offer CS or programming lessons either. I got into it because I was interested in it.

If n is the table size, i the index. Your 1..n index is weird, you should go from 0..n-1 but you can just adjust it by subtracting 1 from i then adding 1 after the mod.
So, i=1, n=4.
(i-1+1)%n+1 = i%n+1 = 2
(i-1-1)%n+1 = (i-2)%n+1 = 4

In conclusion, Google is right and my company's executives are wrong. The lack of women in the tech field is a pipeline problem, not a sexism problem. My company has most inclusive policies imaginable and when we finally get a qualified female engineer, she quits! We cant just magically hire 50 female engineers to balance the team out because there aren't 50 female applicants! There's nothing more we can possibly do and yet we still get a yearly lecture that white males are privileged for having jobs that we must have got though old-boy networks.
>>53970994
Nope, they are behave better than qt girls because they are self sufficient and less entitled
>>53971034
>>53971034
No disagreement from me that there are far fewer female applicants than male applicants for tech jobs. The problem starts earlier - at university my course was 90% men, and before that my A-level math class was about 80% boys.
As for racial diversity: there wasn't a single black person in either.
I can understand the choice of the designers of the ARM ISA to make the exclusive or instruction as EOR instead of XOR (Acorn was a British company, so they might as well not shit on their own language), but why is the inclusive or instruction ORR instead of just OR? For what reason is there an extra R? Just a need to make everything 3 letters?

>Just a need to make everything 3 letters?
Easier and faster interpretter if all the ops have the same length.
>>53971076
it's not sexism/racism, not at university either, it's just that some people are naturally more predisposed to be good at and interested in doing certain things. diversity is about recognizing the varying strengths and weaknesses of individuals, not about forcing everyone to fit the same cookie cutter template.

Any idea whydouble x1 = tblPunkt.get((i+1) % tblPunkt.size()).x;
System.out.println(x1);
double x2 = tblPunkt.get((i-1) % tblPunkt.size()).x;
System.out.println(x2);
it crashes (array index out of bounds) on the 'double x2 = ' line?
Any tips on how to approach problems that require a recursive function? First time I'm working with such problems and I feel like I'm losing my mind trying to come up with the right way for the algorithm to work. I start thinking I'm getting to a solution, then I hit a roadblock and I realize the entire function is wrong working that way, and I have to go back to square one.
>>53971194
Split it into the base case and the recursive step.

a number 1 or an empty array or an array of length 1

Imagine that you want to solve the problem of turning any number, like 4, into a string of numbers below that number down to zero, like "43210"
1. Solve, manually for a very simple case.def count(n):
if n == 0:
return "0"
2. Assume you've solved it for all cases up to, but not including n. Given the solution for (n-1), can you solve for n? In this case, if you have the string "3210", you can get the solution to 4 by appending "4" to the front of "3210", like so:def count(n):
if n == 0:
return "0"
return str(n) + count(n-1)
>>53971191
Oh right, java. % is the remainder, not modulo. So you're going out of bounds because it's returning a negative number.

It's an assembly mnemonic, not the opcode (all actual instructions are 32 bits). Making all mnemonics the same length isn't going to improve interpretation by anything, and it will only make assembling marginally faster (but running an assembler isn't that slow)

So just make a mod function and use that:int mod(int a, int b)
{
return (a % b + b) % b;
}
mod(i+1, tblPunkt.size())
mod(i-1, tblPunkt.size())

Also to illustrate the difference:-1 % 4 = -1
mod(-1, 4) = 3
