    Is it possible to get a remote programmer job from another country?

    Posted: 26 Nov 2020 10:57 AM PST

    I'm from Hungary but I would like to get a remote job from another country if it's possible. Is this a thing or we are still not there yet? Do you have any experience with it? How would the taxation process look like.

    Thank you all in advance.

    First time building an enterprise application for a client, need help with choosing the database!

    Posted: 26 Nov 2020 01:05 PM PST

    Hey guys, thank you for taking yoour time to help me.

    First of all, some backstory, I am a 2 year old experienced python desktop application developer, started with tkinter, made money on the side freelancing. A few weeks ago I switched to PySide2 and it is better over miles, I love it!

    Now the client wants to access data that is generated by the application on any computer.
    My guess would be I need a server host + a database running on that server host? I was thinking of MySQL, is that the right path?

    Do you guys know a good and secure server hoster or a better SQL language?

    Thank you for your help.

    Guys, please help. Iam sort of new to c, and have not been able to set the debugger in vscode for the life of me.

    Posted: 26 Nov 2020 06:04 AM PST

    Iam using cygwin. I can debug in the console, but for some reason debugging through vs code does nothing. I would upload pictures, but that is not allowed here. I have the c plugin installed of course. I also tried following like 3 or 4 different tutorials, but to no avail.

    Bass Transducer/Music-Response Haptic App?

    Posted: 26 Nov 2020 09:54 PM PST

    Hi. The basslet seems dead and some wearables seem too expensive to just 'try out'. I'm wondering why there are no music-responsive haptic/tactile transduction apps for mobile - particularly watchOS. I ignorantly assume this is a market void. Maybe it's not possible? There can't be zero demand.

    Please forgive if wrong sub.

    Thanks.

    Approaches to representing an chopping up array of arrays or matrices?

    Posted: 26 Nov 2020 05:44 PM PST

    Visual

    Say you have a 5 x 5 array. Represented as:

    [a,1,0,0,0]

    [b,2,0,0,0]

    [c,3,0,0,0]

    [d,4,0,0,0]

    [e,5,0,0,0]

    Note the contents are random, just wanted a way to distinguish.

    Say that I want to chop it up sequentially left to right, top to bottom in 4s.

    So then you'd have groups like:

    [a, 1]

    [b, 2]

    and

    [1, 0]

    [2, 0]

    My solution for this would be to have two loops and go with offsets. But wondering is there another way that makes more sense? The languages I would perform this in would be JavaScript and Python.

    HTML - How to force a %age width DIV not to shrink down smaller than its contents?

    Posted: 26 Nov 2020 12:40 PM PST

    https://jsfiddle.net/jmu0b9f7/1/

    If you shrink the window, you'll see that eventually the box of the div will shrink below the width of the text, and the text will overflow the edge of the div.

    Is there a way, just with CSS, to force the DIV to stop shrinking (but otherwise still be 50% of the page width) once it reaches the width of the content?

    3D Connect-4 AI Project: Need help handling explosive search tree!

    Posted: 26 Nov 2020 05:39 PM PST

    Hello!

    I'm currently working on a project for school. I wanted to make my project game related, so I decided to create an AI that is an expert at connect-4. My professor suggested expanding the project to be a 3D version of it, and I'm currently trying to figure out how to make this efficient enough to work.

    My plan was to create a 3D (4x4x4) array to represent the game state, where the player and AI can place any piece (X/O) on any tile they want. They have to connect-4 pieces in any way possible, which could be through multiple layers since it is now 3D. In order to plan the AI's moves, I want to use the minimax algorithm, with Alpha/Beta pruning to help cut down the tree size.

    My huge concern is the fact that we now have up to 64 potential moves instead of just 7 moves in the original 2D version... When using a minimax algorithm, combined with the now 3D array, this can be very problematic as the tree will grow at an explosive rate, creating 64 child nodes for every node evaluated (at the beginning of the game).

    What can I do besides minimax + alpha/beta pruning to help solve this problem? I'm worried that it will only be feasible for the AI to look ahead a few turns due to the complexity of having a branching factor up to 64, while also using a 3D array (which adds to the space being used). In this case, the AI would be pretty much useless until the end of the game when the amount of available moves is reduced drastically.

    Any help would be appreciated! Thank you!

    Help needed on a Login and Register system (C++)

    Posted: 26 Nov 2020 04:43 PM PST

    Currently, in university, I have been assigned a project on making a login and register program, however, I have encountered a problem where the second set and onwards of username and password is not recognised by the program. From another post, I learnt that a while loop is required, and the code should look like this while(!read.eof()) and inside this loop I will check the username and password. But I am not really familiar with using fstream commands. Any help is appreciated. Here is the code, https://github.com/Byome303/Login-system-C-/blob/main/Source.cpp

    Does anyone know if there is an emoji string library for c++?

    Posted: 26 Nov 2020 03:33 AM PST

    I have been trying to find a way to compare to emojis

    eg 🙈== 🙈

    The current string standard library allows the comparisons of strings but out of the few compilers I have tried, most of them run into an error when trying to compare or it does something unexpected.

    ð\u009f\u0099\u0088

    this one emoji is technically 4 characters, I have no idea how that works, something to do with Unicode that I don't understand yet.

    Does anyone know if there is a library that I can run a function

    string a = "🙈🙈"

    eg is_emoji(a[0])

    and get back a Boolean? Or at least some sort of string library that allows emoji comparison?

    Got a little confused on a simple exercise at c#

    Posted: 26 Nov 2020 11:15 AM PST

    Hello everyone, I've got this exercise :

    Write a program that asks the user to enter integer numbers until either 10 numbers have been entered OR a non-integer value (which could be non-numeric) is entered. Then the numbers entered should be displayed in reverse order.

    The thing that confuses me is when I enter a non-integer value into my integers array, it crashes. What should I do to avoid that and just end the loop when a non-integer value is entered?

    code

    int[] x = new int[10];

    int i = 0;

    while (i < 10)

    {

    Console.WriteLine("Please enter the next number: ");

    x[i] = int.Parse(Console.ReadLine());

    i++;

    }

    int y = i-1;

    for (i=y; i >= 0; i--)

    {

    Console.Write (" "+x[i]);

    }

    Console.ReadKey();

    Linear Programming (Excel Solver) Problem..

    Posted: 26 Nov 2020 02:47 PM PST

    First of all, apologies if this is not the right place to ask for help with this.

    I have to use Excel solver for this problem, and while I think I understand what I am trying to work out, I'm just not sure how to do it. Here is the question, and the Excel file:

    DataCaseStudy2020 (1).xlsx

    There are currently 4 recycling facilities (A, B, C and D) that are operating in a city. In addition, the city council is considering 2 potential locations E and F to locate their recycling facilities. Facilities at these locations can be opened and operated at a cost of £80,000 per facility. This expansion is to support their burgeoning metropolitan city. They have divided the city into 12 zones. Each zone has a collection point where they collect recyclable waste from the residents of that zone. The expected amount of waste material collected in these 12 zones is given in the data file. The estimated recycling cost at a facility for the materials collected from a specific zone (per kg) is also provided in the file. This variation occurs because the recycling cost incorporates various components such as transportation cost, wages, grades of the recycling materials collected, etc. In addition, there is a restriction on how many kilograms of waste material that can be processed by a particular facility.

    The waste material that cannot be recycled has to be disposed at a cost of £17.75/kg. They are currently considering the following two options: a. Do not open any new facilities and use only current facilities. b. Open facilities in E and F in addition to current facilities.

    You need to prepare an Excel file with two sheets for two models. In addition to the Excel file, you need to send them a 1-page summary letter, where you explain them briefly your approach and recommendation.

    ​

    So this is my understanding, but I could be way off. I am to minimise cost for each model, one with the new Facilities and one without. My decision variables are how much waste from each Zone is going to each Facility. The restraints are the capacities of each Facility.

    I have no idea how to solve this in Excel Solver... Could anyone help with this? Or is there other examples I can look at that would give me a good idea? I just don't know what commands to use to find the optimal solution. I've never done a question like this before. I'd really appreciate any help with this.
