Okay, made it different now:
package QaE_Objects;public class SomethingIsWrong {
public static void main(String[] args) {
Rectangle myRect = new Rectangle(40,50);
myRect.getWidth();
myRect.getHeight();
System.out.println("my Rect's area is: " +
myRect.area());
}
}package QaE_Objects;
public class Rectangle {
private int height;
private int width;
public Rectangle(int h, int w){
h= this.height;
w= this.width;
}
public int getHeight(){
return height;
}
public int getWidth() {
return width;
}
public int area(){
return this.height * this.width;
}
}
but a question I do still have:
How could I have made the Rectangle class to fit the SomethingIsNotRight main class?
And why do I not need setters here?
Anything I can do better, more secure?
I also think about working on Haskell in the summer

Ive been using Vim and looking for ways to use it better. Watching youtube video about python in vim and pair programming tmux stuff like that.
This guy builds his vim for python somehow. Where I have just been installing the vim from the repo on ubuntu.
What is there to gain through that? I know stuff that used to work like powerline no long works as a plugin and more of a mod to the program itself.
How do I learn about that shit? Modifications to vim that are not addons but actual mods tot he source?

Take a look at WOOT (Without Operational Transformations) which is an alternative to operational transformation for doing collaborative realtime text editing.
You could try implementing a WOOT library in Clojure and do a small web backend that can synchronize the text and store it in a database as JSON or something.
There is an example implementation in Haskell here https://hackage.haskell.org/package/woot

>>54322643
nigger, one of this first shit I uploaded to the internet and the google play store was basically an original take on breakout.
And it was something polished.
no excuses nigga.
I'm doing a couple things for work. One is a JSF (Java ServerFaces) application. JSF sucks. It uses this stupid "component based" model for trying to write web applications and it's terrible. Not only is it fundamentally bad, but it's also incredibly buggy. I spend almost every day having some issue only to find a Stack Overflow page describing how it's actually a bug in the implementation.
The other project is a replacement for some database export code. The original developer is one of these "geniuses" who sits on a high horse of complex design patterns. He's the kind of person who would write Enterprise Fizzbuzz without any sort of irony. The utility to export some database tables is so horrifically complex and over designed. Everything is a fucking abstract class like AbstractOracleTable or AbstractIntegerField with an inheritance hierarchy longer than his virginity streak. It's thousands of lines of code and reinvents the wheel for god damn everything. I was able to rewrite it in about an hour. The hard part is convincing this other team to actual use it. I keep telling them that I'm no longer supporting the old tool so if they have issues then they're up shit creek. They're still resisting and of course they are falling behind schedule because they have to stop everything they're doing every couple days to figure out why the old application is broken again.
Even when this export utility "works" (doesn't crash), it still produces bad output. So even in the best case scenario, we still have to run the export files through a custom parser we wrote to get the exported data back into the correct format.
>>54322688

>>54322667
I'm working on some collaborative editing and I'm curious if anybody could tell me if it's recommended to create a lot of tables?
I want to create a table for each project. Each project contains a lot of documents.

This.
Compared to the garbage that gets on phones and greenlight, the crap I throw in the trash for being too broken, simple or ill-thought-out are AAA masterpieces.
Hell, the text adventure I made in qbasic when I was 8 is objectively a significantly better game than crap like gone homo and whatnot, yet it was quite short and purely text-based (with colors, music, player stats and skills, etc.) so I never dared show it to anybody.
>>54322767
It's fine, but the syntax is pretty shitty and the ownership system gets in your way too much.
Just benchmark my shit up senpai.from random import random

for language in languages:
print language+':', random()*100
Is there an algorithm to shuffle an array but to keep each element within a certain distance from its original position? I was thinking of splitting the array into distinct subgroups and shuffling each. Is there a better way?
>>54322810
The syntax is comfortably C-like for the pajeet while also offering high-level constructs for people who know what they're doing, all the while retaining consistency compared to the likes of C++ which require intensely complex backtracking parsers to parse.
The ownership system is the best way to ensure memory-safety, and the easy way out is just an @ away if performance doesn't matter.
>>54322834
Start at the first item. Pick a random item at most K units forward. Swap them. Register both of them. Go to the next unswapped element.
>>54322851
>The syntax is comfortably C-like for the pajeet
were pointers too hard for ya, buddy?
>>54322834
It's not an algorithm if it produces a random result.

This would be very good for parallelization so I guess it would be a good idea.

How well do you know Python?
Alright niggers, what's the good lisp. Something with a good standard library.
>>54322867
Rust essentially retains pointer syntax, but the semantics are different so as to prevent bugs by rejecting bad programs. This allows pajeet to work for you for pennies without making your program unpublishable, while also ensuring mission-critical programs worked on by the foremost experts in the field actually work and don't reproduce therac-25.
Understood, pajeet? This is good for you!
>>54322901
They all suck. Even the ones with the best standard libraries (racket and common lisp) are not good enough.

Thanks, but I don't have a strong background in maths so it probably won't help.
>>54322933
>Where are you getting that definition of algorithm?
I explained myself badly there. Yes an algorithm can create a randomized result but what I meant was that the algorithm he is looking for isn't an 'algorithm' since it doesn't have a deterministic time complexity.
>>54322911
Racket actually looks pretty good. Even the web stuff in the standard library looks pretty straightforward.
I might have to start tinkering with it.
>>54322926
Because that's not general programming. Carmack can afford to rewrite the entire standard library in an afternoon, you can't. Carmack et al. can produce 10 man-years' worth of work in a week, you can't. If you could, literally any language, no matter how niche, could be used for any task, no matter how common.

Isn't python a very self-explanatory language, how much is there to *know*?
I can do simple things like web scraping and bash-tier scripting

It's just that compared to python, C++ seems impossible
>>54322969
Try doing some OOP in Python before jumping to C++.
Or you might try C instead which doesn't make use of classes.
>>54322959
Then fuck is your requirements for a "good standard library" ? Racket has the most extensive one of any language, no doubts about it. lazy evaluation, continuation capture, hygienic macros, best module system, threading, and more, where else?

I know that /g/ loves Haskell so hopefully this is a good place to ask.
I've recently been learning a lot about functional programming concepts via work I've been doing with JavaScript and Scala.
>inb4 language flamewar
At this point I know "babby's first fp concepts" like streams, monads, higher order functions, currying, immutability etc. Now that I've got the basics, I want to pick up a "strict" functional language so that I can learn about what it means to build software completely in a functional style, rather than just using functional concepts within an imperative-style program. I've decided on Haskell.
I've worked through a good amount of "Learn You a Haskell for Great Good!" but I don't learn very well from books. I really need a project to work on where I'm forced to figure out how to use the language to achieve a desired result, rather than just following steps and trying to memorize what I'm shown.
So, does anyone have any good ideas for a reasonably complex "first project" in Haskell? I'm looking for something like the "ToDo App" that JS devs use to compare libraries and frameworks. I haven't really seen this kind of thing in the Haskell world. I want something complex enough that I'll have to really think about how to use the language, but not so complex that it'll take me more than 40-50 hours to complete.
Thanks in advance!

So I made this function that computes the logarithm using taylor sums. The problem is that it returns garbage values. I made it print the values of the sum and they are correct for ln(5), but it returns a bigass number.double ln(double x)
{
int i;
double sum;
if(x>0.5f)
{ return sum;
for(i=1; i<100;++i)
{
sum= sum+ pow((x-1)/x,i)/i;
}
}
else return -1;
}
What is wrong /dpt/? It only works for x>1/2 so -1 is the stupid user input number.
>>54323122
Maybe initialize sum to 0.
>>54323116
You can make the algorithm to be the compexity of n because permutation matrix are rare possed matrixex + then only have one 1 i each row and each column, and when you multiply them the you will get one big matrix and with it you can multiply the array you have and thats how you will get the shift you want ;)

for (int i=0;i<(sizeof(x)/sizeof(x[0]);i++)

something went wrong somewhere.
i think my function doesnt grab my char array. anyone has a clue?
>>54323082
search github for something along the lines oflanguage:Haskell stars:<50
stars limit is there to exclude most bigger projects that will be unfeasible to implement
you could also try repo size limit in kilobytes e.g.size:<100
Scroll through projects, see what you'd like to implement and as a bonus when you're finished you'll have a 'reference' implementation to compare with that probably doesn't suck massively (assuming repo has some stars/forks)

Why sizeof(x[0])? Use the size of the unit (char). And you said in the for loop that i=0 and asked for a return value. When you return you quit that function. (You return to the other one)
Hello, /dpt/.
I would like to write a script that downloads all files from mega.co.nz links on a blog.
Can someone please point me in the right direction on how to start?
Feel free to send me to /sqt/ if stuff like this isn't usually discussed here.
>>54323246
wut?
return ends the function and returns to main() again, return i.
char is 1 bit.
sizeof("fuckyou") = 7.
sizeof(x[0])=1 cause 1 bit.
so 7/1 = 7, is quite redundant in terms of chars but useful in other primitive data types.
the mistake is somewhere else

>>54322614
Certain plugins depend on having language support compiled in. The plugin community is pretty against writing plugins in anything other than vimscript unless you've got a good reason, so most plugins don't need the language support.
There are a few notable exceptions, mostly depending on Python support and a couple needing Ruby. But most package managers have a few different versions of vim with different language support, so you won't need to compile your own. I think ubuntu's vim with the most language support is vim-nox if I remember correctly.

Most of those really don't matter. I'm sure you can find out, but you're going down a rathole with that, and won't come out with much to show.

no. any thread gallery mode would be handled in the thread preview window, but instead of a column it would be a grid. that's the best way to handle it.

I am designing a small weather station that has an ambient light sensor. It uses a 5 mm LED as a sensor and a transimpedance amplifier circuit. Its linear measurement range is approximately from 500 to 10 000 lux. Is this enough for outdoor measurements? Pic related..

>>54323879

>>54324471
Are you really using an LED as the sensor, or is it an LDR like a sensible person would use?
Also, the light sensor on my chinkphone can measure ambient light between 5 and 30,000 lux, so you probably need a larger range.
The lower end isn't quite so important if you're in a built-up area with enough light pollution that it never really gets properly dark, but will definitely make a difference in rural areas.
I'd suggest using a sensor with a usable range of at least 100 - 20,000 lux.

>>54324902
It gives a linear response to lux, but maybe consider whether that's actually a good thing or not.
The visible difference between 20,000 and 25,000 is much harder to detect by eye than the difference between 50 and 100 lux.
Either through additional circuitry or using a different component, you should be getting a logarithmic response back to make the data actually useful.

Some are retard easy because they just require some small modification to the algorithm/data structure just reviewed in the chapter and some are retard hard.

>>54325555
>A small handful of people who identify as libertarian are against the military, but the vast majority are in favour.
No they aren't, at least not in favor of what we have currently. Libertarians believe in a state, usually (that shouldn't be a surprise to you) and they think defense is one of the functions of the state.
I don't think the state has any legitimate functions.
>>54325521
>GPL: nobody can steal your shit and sell it as their own.
not 100% correct.
you can sell GPL shit made by someone else, you just have to give your customer the GPL and also the source code, in case they ask for it. sure the copyright is owned by the creator, but the software can be sold by someone else.
>>54325459

>Would you like some help moving those goalposts?
The goalposts haven't been moved. That's why I said "ancaps and serious libertarians". The things you are talking about (hating the state) are usually reserved for fringe elements of libertarian-minded people.
You conflated these fringe elements with the general group, and that was your undoing.

I can use Skype or Kik or whatever you want to talk over but it'd be really nice to have someone to talk to about stuff since I don't like anyone in my class.
>>54325459
It should be noted that Libertarians are not Anarchists like Jacob Spinney in that video I linked. What makes a Libertarian a Libertarian is the desire for a minimal state, not a non-existent one. An economically successful stateless system would inevitably be crushed by rival militaries. What keeps China and Russia playing nice instead of invading the US with their rather large militaries? A solid, unified military... with as many aircraft carriers as the rest of the world combined.
Clearly a state is necessary. What a Libertarian argues for is that we don't have the state intervening in business or in our daily lives.
>>54325555
Most Libertarians I've met are for a military, but against its use to police the fucking world. That said, I'm personally okay with sending our military out against ISIS, since they're a threat to more than just the region they're inhabiting.
>>54325521
Why do you believe that someone forking your program and using it in some proprietary code is "stealing"? No one is being denied the use of your code.
>>54325501
Well Clojure's a pretty cool Lisp if you're interested in going that way. It's like Scheme... with more sanely named builtin functions and keywords, and with a fairly large standard library depending on if you're targeting the JVM, the CLR, or JavaScript (and a sizable core standard library that's available on all platforms).
>>54325686
what's the issue? let someone pay you to make a specialised version of a GPL project. Then there's no issue.
Most people generally won't be happy about software they pay for being open source and freely distributed. Might as well just charge for custom software like most freelancers.
