    Study Group for Web Dev

    Posted: 29 Oct 2020 04:27 PM PDT

    Hello.

    I am studying to be a software engineer. I am looking to form a study group of people who are also looking to become software engineers. I figured we could treat it a bit like a study hall and all be working on our own things, but we talk to each other when we get stuck?

    I'd be willing to go in on a Zoom plan if we get enough regular participants. :)

    DM if you want. Comment. Whatevs. Just looking to form a group so we're all better at staying accountable for ourselves! :)

    Little bit about me: I'm like intermediate level I think. I haven't really worked on fullstack projects yet, but I'm okay at front end. I have experience with JS, React, CSS, HTML, Bootstrap, jQuery, Ajax.

    I'm open to whatever :)

    Want to make an app, don't know where to start

    Posted: 29 Oct 2020 07:15 PM PDT

    Lately ive been getting kinda frustrated with keeping inventory in my Dungeons and Dragons games. Ive been trying to learn programming off and on for the past few years but could never figure out what to make until now. I would "like" to create some sort of inventory app for my phone that lets me input my strength, select what encumbrance ruleset, then finally add whatever items and calculate my weight and maybe even save it to a file/character. My issue is that I have no idea what engines to have my app run on (if at all) and every time I try googling and try figuring this out on my own but I always come across engines for gaming which is not necessarily what im looking for. I even tried out unity but I feel like im getting nowhere with that. If it helps at all Ive got the basics of python and c++ down. Any help here would be SUPER appreciated!

    Best way to "get back into" advanced SQL

    Posted: 29 Oct 2020 08:47 PM PDT

    Hey everyone!

    I'm starting a new position in a few weeks that requires some rigorous SQL to keep myself afloat. Unfortunately, I've been in a position the last few years where all the data pulls were out of my hand, so I've written next to none in that time. So to get to the point: I once was deeper into SQL in my old-old programmer job, but now I got a few weeks to ramp back up into this rusted skill and I'd like some guidance! Where would you recommend I look/read/practice to kind of prep myself back up for intensive day-to-day SQL, as someone who has a background in it?

    How to study and learn coding effectively?

    Posted: 29 Oct 2020 07:38 PM PDT

    How to study and resolve coding issues as a mom?

    I have a full-time job, a toddler who is very very demanding and I do all the chores at home. I took a break from my masters since this pandemic and my mom in law passed (she helped me with taking care of my kid so :( it's sad that she is not around anymore). I badly wanted to study and write code again, but I am having a hard time answering maybe leetcode or hackerrank questions because I feel lost and I don't know how to proceed.
    My questions are:

    1. Are there any tips on how to develop algorithmic thinking to solve programming problems?
    2. I do know basic data structures/control/decision flows, syntaxes, etc.. but for some reason, I am having a hard time applying them to programming problems.
    3. How to organize my time as a mother, a wife, and an employee? I am currently a software QA

    Thanks, everyone in advance :)

    Why am is my 'document.getElementById' still returning 'null'?

    Posted: 29 Oct 2020 07:39 PM PDT

    Hello,

    I've gone through the process of debugging my code multiple times, but yet, I still get a TypeError: Cannot set property 'innerHTML' of null error.

    I'm making a simple clicker game, simply to test my ability to do so. I've made a post about this same project just a few days before this, but now I've run into another problem which I cannot find an answer to. I've looked up many things, and I've read many different StackOverflow posts and articles from all over the internet, but none of them seem to point out my problem.

    My problem is this: I have a program of a game, written in Javascript, HTML, and CSS. I am just getting to the "upgrades" part of the standard "clicker game". I've made a class for all of my upgrades to fit into, and I'm immediately running into my first problem(s). The HTML button element that seems to be causing the problem is shown below:

    <button onclick="upgrade1.buy()">(100c) kilo-clicker | <span id="upgrade1">0</span></button>;

    This is paired with the following Javascript statement that returns null:

    console.log(document.getElementById("upgrade1")); //Output 'null'

    Would anybody know why this may be?


    If anymore information is needed, you can find the rest of the code on Repl.it here. Thanks a ton! :)

    2nd year CS help

    Posted: 29 Oct 2020 09:54 PM PDT

    One month in to my second year of my CS course, ans the difficulty has skyrocketed. Went from coding a terminal program to book flights to reimplementing malloc. (Doesn't help when my lecturer isn't giving any lectures or guides). My programming skills are obviously far behind but having courseworks due one after another isn't giving me a lot of free time to practice. I'm so incredibly lost and hopeless and feel like there's a part of my course that I've somehow completely missed. Any tips on what I can do?

    Patterns for error handling?

    Posted: 29 Oct 2020 07:37 PM PDT

    Is there a resource for popular patterns for handling coding related errors (ie. not related to communication protocols, APIs, etc.). For example, if a function fails, receives bad input, can't return expected output or has other issues, should it return an error status, have an optional value or throw an exception?

    Fellow noobs: How is learning your first language going?

    Posted: 29 Oct 2020 06:45 PM PDT

    I've been studying C++ online for the past two months so Hello World is pretty fresh in my mind but I feel good about the progress I'm making (I wish functions were clicking more than they are but I'm getting there). To those diving in without past experience, how's it going for you? To those with experience, how did you feel early on? Any words of encouragement or advice?

    Company is offering reimbursed training/courses. Which do I take? (SQL, Python)

    Posted: 29 Oct 2020 09:37 PM PDT

    My company is offering to pay for training or programming courses. I am 25, I've used python in a beginner programming college course and haven't used it since. I currently work with NetSuite which uses some SQL. I would like to learn more python so I can get a better job eventually but I also want to learn more SQL to help me in my current job. I'm leaning more toward python but want to take advantage of a free course/training.

    Do you recommend any one online training/certification/course for python or SQL?

    Clarification on recursion and python.

    Posted: 29 Oct 2020 07:40 PM PDT

    Code Block 1: u,d,l,r = search(up), search(down), search(left), search(right) return u or d or l or r Code Block 2: res = search(up) or search(d) or search(l) or search(r) return res 

    Hello World! In these 2 blocks, I was doing a problem where I used DFS to search and basically i just need one of these searches to return true so my question is would code block 2 run faster? I was thinking it would be faster because if search(up) evaluates to True then res will always be True.

    Another follow up question with this is when search(up) evaluates true then would it still evaluate the other recursive search calls?

    as appose to code block 1 where it has to recurse through each u,d,l,r searches maybe this code is taking longer to run?

    C++ Beginner Question

    Posted: 29 Oct 2020 10:50 PM PDT

    Hey guys, I'm learning C++ for the first time and I'm writing a program where I'm using Scanf to get a value from the user and then rejecting everything else that isn't what I want. I want the user to enter either 0, 1, or 2 and ask them for a value again if they put in something different. The issue is though that if they enter a word or character it seems to evaluate as 0 and keep going through the program. How can I make it so when they enter a word or char it treats it like an incorrect input?

    Example of what I'm doing.

    int input;

    printf("Please enter a value 0, 1, or 2");

    scanf("%d", %input);

    while(input < 0 || input > 2){

    ask them again}

    C# and connectinng to VPN ?

    Posted: 29 Oct 2020 08:27 PM PDT

    So I've been looking into how it would be possible to connect to a VPN by C# code, it seems like OpenVPN is the most common protocol VPN services use, but it's apparently not as easy to setup.. There are many different protocols like Ikev2, l2tp, etc. Hard thing is choosing some way of doing that, which would be compatible with as many VPN services as possible.

    Does anyone here know of some good C# API that would be suitable for this kind of task? I just need to be able to switch IPs on demand when a method in the GUI app is executed.

    Questions regarding github

    Posted: 29 Oct 2020 09:56 PM PDT

    So I am looking at using git for a school project with another team member and we are looking for functionality where we can edit the same files and add our changes.

    I have been reading into git and I am wondering, this specific case and how git handles it.

    So lets say person X and Y edit the same .cpp file at the same time, so they create a fork of the master branch and begin their edits. Person X and Y make unique edits to the .cpp, when they go to commit, how does git merge both their changes into one .cpp?

    If there are any guides I can read to learn this, all help would be much appreciated.

    I'm Getting Lag in Collaborative Drawing App

    Posted: 29 Oct 2020 08:39 PM PDT

    Hi guys! I'm really new to canvas and I'm using socket.io with it for real-time communication between two users.

    Right now I have two tabs open on localhost and when I'm drawing on one screen, and the same image is being drawn on the second screen. However, the image on the second screen is dotted instead of being a solid line. This only happens when I draw lines moving my mouse really quickly.

    Heres an image of the example: https://i.gyazo.com/4c913df9329ddc9d05c9fa6b0a9ac8e1.png

    Any ideas what might be going on? I've noticed that I'm having trouble just console.log()'ing all the pixels and if I move my mouse fast enough, it'll skip the console.log() on some pixels.

    I know it's possible as I found someone who did it, but can't seem to figure out how... Any help would be greatly appreciated thanks!

    This is the code for the canvas: https://github.com/jeffreycao1998/drawlab/blob/main/client/src/components/WhiteBoard.js

    Homework question about arrays

    Posted: 29 Oct 2020 08:05 PM PDT

    Q: Suppose that an instructor assigns different letter grades based on points earned on a 10-point quiz, and that all scores have been verified to be between 0 and 10 inclusive. Also suppose that four possible letter grades can be assigned and that 9 or 10 points is an A, 7 or 8 points is a B, 6 points is a C, and 5 or fewer points is an F. To assign letter grades, the most efficient numeric array containing point values would contain _________ elements.

    A.3

    B.4

    C.5

    D.10

    The answer was 3, but I don't really get why. Wouldn't your array have to have at least 4 elements, one for the A grade, one for the B grade, one for the C grade, and one for the F grade?

    Can someone please help me with an R^2 method using Numpy?

    Posted: 29 Oct 2020 07:19 PM PDT

    I'm trying to create a method R-squared to calculate the coefficient of determination. I'm aware that a method exists already in Python (in sklearn I believe) but I'm trying to make one from scratch.

    This is what I came up with it but it's not working:

    R_square_val = (np.corrcoef(y_true, y_pred)[0, 1])**2 return R_square_val 

    TIA!

    drag and drop doesnt work when redirected to a html with it

    Posted: 29 Oct 2020 10:39 PM PDT

    Im creating a simple app with login and a kanban board. When user logins site redirects him to kanban board. When I start html with kanban board (home.html) the drag and drop for list items works fine, but when I start try to first login and then access kanban board, kanban board is shown but drag and drop doesn't work. I am trying to drag and drop list-items from one list to another.when a user click login it redirects to /home which is kanban board. so far I've only written it for admin but it doesn't matter for now.

    here is my code:

    https://github.com/noob138138/kanbanBoard.git

    (home.html and homecontroller refers to kanban board)

    As i said, when i try to open home.html it works fine, but when i open index.html and login as username=admin and password=admin , drag and drop doesn't work. I assume it is because of setTimeouts in kanban.js cause probles when redirecting from login.html to home.html but I don't know how to fix this problem.

    Should I learn multiple things at once?

    Posted: 29 Oct 2020 09:48 PM PDT

    I currently know python and I am learning Django web development. I also want to learn C# as I also want to dive into game dev with Unity 3D. Should I learn Django and C# simultaneously? My college classes will also start soon, they will teach C, although I know C but I don't use it so it's fuzzy. That means I will have to learn C too.
