Should My Software Developer Be Liable for Bugs That Cost me Thousands of $?

Posted: 18 Oct 2018 08:40 AM PDT

I have an online site, and I hired a PHP developer that was supposed to be trusted. However, him and my parthner began talking and when the update was done for my site, there was a bug that allowed users to create fake orders by switching unpaid orders status to a paid status when it was not paid for. About $3000-4000 in unpaid orders were given because of the bug. Now my developer and my business partner are working on a new business together, so I am assuming that they worked together to steal money to open a seperate business and when I confront them they say they aren't allowed to speak of their seperate business. Is there anything I can do against my developer for glitches I think he intentionally implemented if i don't have much evidence? it seems pretty bogus how fake orders could just magically happen like that.

Why is asking on stackoverflow so horrible?

Posted: 18 Oct 2018 08:59 PM PDT

This is a bit of a rant, with a throwaway. Sorry in advance.

I go on SO to ask a technical technical code-related question, expecting one of the two outcomes: an answer, or silence.

*That's* my mistake. In return for my technical question, I get what amounts to a colonoscopy, by what appear to be 14 year old "engineers", who racked up internet points asserting wrong information with brazen confidence.

Why is everyone responding in underhanded, condescending tone, under a thin veil of technical clarification?

Why is it that people who don't know the answer, nor care to even understand the question, need to comment, then upvote their incorrect comments, all meanwhile downvoting my question?

I feel as if asking a question on SO is equivalent to giving up whatever dignity you have, or be downvoted for *no logical reason*. I don't carry a big ego, and like all engineers - I make errors, but when I go on SO - I have to really go out of my way to keep composure.

Once, every few years, I might be in the zone and suddenly think myself into a corner; or start thinking in circles - and I want to ping another human, a coworker, or someone who can write code - and bounce a question off of them. I code on my own, and SO seems like a good place to do that. But now that it's a polluted cesspool of elitist children - I don't want to use it. It feels as if it brings no value to asking questions.

Does anyone feel the same? Here's a link to my most recent question:https://stackoverflow.com/questions/52867773/check-for-inheritance-at-runtime-having-only-one-of-the-types-and-void/52869489#52869489

I'm not asking anyone here to judge my own answer to my own question (it was done late last evening, and I wanted a place to jot it down), I'm still yet to refine it. I just want to know if you had a similar shit experience on SO.

Also, if you notice something terrible in my question - I welcome feedback, I'd really like to rationalize what happened here.

Thanks in advance

Is it normal to question the spelling of a word (like in a variable) after you read it like 100 times while coding?

Posted: 18 Oct 2018 03:35 PM PDT

You know how if you say the same word again and again and again you stop being able to pronounce it?

I'm experiencing the same thing but with reading. For instance, I have a variable called 'year' in my program, and I've read it so many times that I'm like, "What... Y-E-A-R is that really how you spell year? That looks so wrong..."

Is this normal with programming or am I just crazy?

How would you create an algorithm that creates sudokus?

Posted: 18 Oct 2018 08:14 AM PDT

The idea is to create an algorithm that fills a 9x9 grid with numbers from 1 to 9 and with the rules of the sudokus. Any ideas? (The programming language is indiferent)

How many modern mobile devices would it take to meet the computational ability of a supercomputer?

Posted: 18 Oct 2018 11:34 AM PDT

Are we talking about a 1000:1 scale? 100,000:1? Sounds pretty vague, I know. But I'm fine with guestimate/vague answers. Just trying to get a general understanding.

Bonus question: Are there many use cases in which a single task can be distributed across multiple devices without shared memory?

Knights Tour Backtracking

Posted: 18 Oct 2018 05:24 PM PDT

I am trying to code the solution myself for an 8 x 8 chess Board. And pretty new with backtracking problems and I am really not sure where i am getting this wrong.

#include <bits/stdc++.h>

using namespace std;

void printSolution(int** arr, int n){

for(int i = 0; i<n; i++){ for(int j = 0; j<n; j++){ cout << arr\[i\]\[j\] << " "; } cout << endl; } cout << endl;

}

bool isSafe(int **board, int x, int y){

if(x>=8 || y>=8 || x<0 || y<0 || board\[x\]\[y\] != -1){ return false; } return true;

}

void knightsTourHelper(int **board, int x, int y, int n,int xMoves[], int yMoves[]){

if(n == 63){ board\[x\]\[y\] = 63; printSolution(board, 8); return; }

int xNext, yNext; for(int i = 0; i < 8; i++){ cout << n << endl; xNext = x+xMoves\[i\]; yNext = y+yMoves\[i\]; if(isSafe(board, xNext, yNext)){ board\[xNext\]\[yNext\] = n; knightsTourHelper(board, xNext, yNext, n+1, xMoves, yMoves); } }

board[x][y] = -1;

return;

}

void knightsTour(int n){

int \*\*board = new int\*\[n\]; for(int i = 0; i < n; i++){ board\[i\] = new int\[n\];

for(int i = 0; i < n; i++){ for(int j = 0; j < n; j++){ board\[i\]\[j\] = -1; } }

int xMoves\[\] = {2, 2, -2, -2, 1, 1, -1, -1}; int yMoves\[\] = {1, -1, 1, -1, 2, -2, -2, 2}; board\[0\]\[0\]=0;

knightsTourHelper(board, 0, 0, 1, xMoves, yMoves);

for(int i = 0 ; i < 8 ; i++){ delete\[\] board\[i\]; }

delete\[\] board;

}

using namespace std;

int main(){

knightsTour(8); return 0;

}

Which programing language should I learn next, that complements what I already know?

Posted: 18 Oct 2018 05:20 PM PDT

When I was in classes, in 2017, I had learned C++, Visual Basic, MySQL, HTML, CSS, and JavaScript. I recently tried to teach myself PHP, to have something more in my job hunt. Though I haven't worked with PHP hands-on, just lessons and tutorials on the website. So if I got a job with it, I think I'd need to have the website open while programming, but I think I could do it, knowing the concepts, basics, and some more in-depth stuff. Though I'm a bit off topic here. What I wanna know, what, if any, programming language should I try to learn next? Preferably one that can work within one of the languages I already know.

Thanks for any help.

difference between prime numbers

Posted: 18 Oct 2018 04:46 PM PDT

I am trying to write a program that takes an input and finds the first prime above the input and then checks if the input itself is prime if not it takes 1 away and checks that number until it finds the first prime on the input or below it. The program then prints the difference between the two primes.Sorry if Im doing something really dumb Im pretty tired its for upcoming lab question and the input has to be a number in an array from 2-1000

import java.util.Scanner; public class arrays{ public static void main(String [] args){ Scanner scan=new Scanner(System.in); int p1=0; int p2=0; int [] myArray=new int[1001]; for(int i=0;i<myArray.length;i++){ myArray[i]=i; } int num=scan.nextInt(); for(int i=num;i>=2;i--){ boolean isprime=true; //System.out.println(i); for(int div=2;div<=myArray[i]/2;div++){ if(myArray[i]%div==0){ isprime=false; } } if(isprime==true){ p1=myArray[i]; i=1; } } for (int i=num+1;i<1001;i++){ boolean isprime2=true; System.out.println(myArray[i]); for(int div=2;div<=myArray[i]/2;div++){ if(myArray[i]%div==0){ isprime2=false; } if(isprime2==true){ p2=myArray[i]; i=1001; } } } int diff=p2-p1; //System.out.println(diff); } }

First year Coding problem? easy question

Posted: 18 Oct 2018 04:41 PM PDT

Alright so im in a first year CSC course for non CSC majors so please keep it simple.

im simply trying to add a facebook "like" button into my website. i successfully added one to a much simpler website (pretty much just the like button and a paragraph) but now im trying to add it to a website with more stuff going on and when i load the page (that works completely fine without the "like" button code) it says:

XML Parsing Error: not well-formed Location: file:///C:/Users/Jon/Desktop/CSC101/lab/lab/vacation.xhtml Line Number 64, Column 130:

for reference this is the line of code im trying to put in

which works perfectly fine in my other website, and is literally the exact line of code our professor gave us... any help?

Finding keywords in XML documents

Posted: 18 Oct 2018 12:35 PM PDT

I've been at a loss trying to do this so any help is beyond appreciated. I have a folder with thousands of XML files. I need to locate keywords (about 12 in total) scattered throughout those files. I'd like a script that will print out (to one massive CSV) information on where each keyword is found. This includes: the file name, line number, and the preceding parent elements. I'm not a programmer, so I really have no idea where to begin. I'm sure a script already exists that does this.

Scheduling Volunteers based on their Availability

Posted: 18 Oct 2018 03:37 PM PDT

Language: probably MATLAB

I'm looking to write a program that optimally schedules volunteers based on their availability.

There are two shifts every day the volunteers can sign up for. Each shift takes a maximum of four people. Each week, a Google Form is sent out where the volunteers mark for each time slot whether they are available or unavailable. Each volunteer is then assigned one time slot to work for the week (unless they specify on the form they want two time slots).

I'd like to write a program that places the volunteers so that the maximum number of time slots are filled.

I can see how to do this by starting with the volunteer with the least availability, assigning them to a random one slot where they are available, and then moving to the next least available volunteer.

But I'd like to know if anyone knows of any resources or other code people have written that covers this or a similar problem (in a more efficient/optimized way). I've tried Googling for some of this stuff, but I haven't been successful at wording this problem in a way where Google gives pertinent results.

Tips to catch cheating?

Posted: 18 Oct 2018 02:47 PM PDT

I'm very new to teaching programming (also teaching in general).

I gave an assignment which is very easily google-able (the professor I'm teaching for has used this assignment for many years), and I provided very basic pseudocode for how to implement the functions, so I expect that there will be several similarities among the codes I receive, at least among the students who follow the pseudocode, which I assume will be everyone.

What are your tips for catching cheating in this regard? I can tell very obvious cheating, such as when code is literally copy/paste of someone else's code, but, idk. I imagine this is something I will get better at as time goes on. How do you approach this?

Why do C and C++ compilers (gcc, clang) and rust compiler take so long to build? Does it have to be that way?

Posted: 18 Oct 2018 02:44 PM PDT

I'm talking about building the C compiler.

gcc and clang take about half an hour to build. The rust compiler takes a long time to build too.

Does it really have to take that long? Would it be possible for someone to make a decent C or C++ compiler that builds in a fraction of the time? Or is there a fundamental reason that it has to take such a long time.

I know that tcc builds very fast (and it's a "real" compiler because it can build gcc and linux), but I think it's missing a lot of the optimizations that the others do - so maybe the optimizations take all the work?

I was also thinking about how interpreted languages can start running the program straight away at the cost of running a bit little slower. Since they can run with 0 compiling time, it seems crazy to wait an hour for gcc to build. Any thoughts?

Why is my typescript for loop not executing the code inside it during the last iteration?

Posted: 18 Oct 2018 08:24 AM PDT

I have a simple for loop with console logs to try and debug

 for (var i=0; i < this.balances.length ; i++ ){ console.log(this.balances.length); this.totalBal += parseFloat(this.balances[i].balance); console.log(this.totalBal) i++; }

the output to the console is

16:19:39.869 app.component.ts:47 3 16:19:39.870 app.component.ts:49 9751.5 16:19:39.873 app.component.ts:47 3 16:19:39.874 app.component.ts:49 19670.5

As you can see the this.balances array has 3 elements, but the code inside the loop is only getting executed twice.

I know this is the most basic thing in programming but I'm stumped as to why it is not executing the 3rd time.

Can anyone help?

Thanks.

Need some help in determining string length C

Posted: 18 Oct 2018 08:07 AM PDT

Okay, an assignment I'm working on has the user input a mix of an X amount of uppercase and lowercase letters. It wants me to print out a new string where the casing of the letters is switched. The latter doesn't seem too difficult, but it's the former I need help with.

If I don't know how many characters my user is going to put in, how do I know if I will make my string big enough?

Here are some of the instructions

Headless Safari available?

Posted: 18 Oct 2018 08:05 AM PDT

I've build a crawler with Headless Chrome + Nodejs + Puppeteer because I need Javascript and detailed API access like filtering every single request for a string and then getting parameters out of that string.

Any lib outside of Puppeteer failed to deliver that API level for Headless Chrome.

But now I need to test sites for ITP impact from Safari 12, so I would need a Headless Safari - is this possible? I don't own a Mac but would get access to one from my employer if necessary.

I hate pointless paperwork. Even documentation, I don't like doing more than documenting in source and using some tool to do the functions. Documentation makes me want to switch fields even. Why is this part of the industry still not automated fully?
