    I feel like everything is easier since I started learning basic Python/CS learn programming

    I feel like everything is easier since I started learning basic Python/CS

    Posted: 12 Apr 2021 02:38 PM PDT

    I've been doing MIT's Edx Python courses (finished the first one, just started the second) and in just two months I feel like a completely different person. The first 4 weeks took me like 6-8 hours/day of studying, and I was mentally exhausted afterward with no energy for other things. It took me a while to grasp new concepts. I've always been a painfully slow reader/learner.

    Fast forward a couple months, and I think all that mental effort has re-wired my brain. I picked up a couple hobbies easily that I couldn't grasp before. Maybe it's because my focus is better; I can focus for a few hours instead of just 15 minutes like before. I can learn something new (ex. knitting techniques) on the first or second try, where it used to be difficult to get right with my best effort.

    I get now why they encourage learning something mentally stimulating like music or basic programming as a gen ed. I feel much more capable of everything than I did a couple months ago. At this point, I wanna keep up the work for the other benefits, in addition to the actual programming itself. :)

    I quit my job for a Coding Bootcamp :D

    Posted: 12 Apr 2021 11:55 AM PDT

    Hi guys!

    I was a pediatric home care nurse, but I recently resigned to join Coding Dojo.

    I know I see a lot of negative comments on bootcamps, but I'm really the type of person that needs guidance and a schedule to study and practice. And self studying was very inconsistent for me.

    I start April 19th. I'll update you guys how it's going!

    If anyone else is in this cohort, or if you have any advice, please let me know! I'm excited and scared at the same time lol.

    Edit- Thank you guys for the support and advice. Sorry if I wasn't able to reply back, but I really appreciate you guys being a supportive community.

    Be wary of Udacity - opt for books and cheaper sites like Udemy

    Posted: 12 Apr 2021 06:49 PM PDT

    Hey folks,

    I wanted to post a PSA about Udacity. This is just my personal opinion but hopefully it helps people trying to pick up a new tech stack.

    I've signed up for several Udacity courses in the past. I haven't completed a single one. I say this as someone who has been working as a developer for 3+ years now and who regularly gets through books and similar courses without issue. My biggest complaint? Their code quickly becomes outdated and broken, and if you're just beginning as a programmer, this is going to frustrate and stymy you more than help you.

    Will you run into a lot of errors as a developer that you need to research and google? Yes. But if you're just starting out, that's the last thing you want. In my opinion, you need to have at least a basic foundation in programming to gain anything from struggling through cryptic error messages on your own.

    As an example, I started Udacity's Blockchain developer nanodegree (again) today. I had started it 2 years back and decided to cancel, but I figured I'd give it another shot. When I went to work on the first project, I downloaded the boilerplate code and ran `npm install` - immediately got a deluge of error messages. THIS IS NOT OK. Boilerplate code that has had no modification should not immediately break. I double-checked that I was running the right version of node and npm. Incidentally, this is the same thing that happened 2 years ago, and it discouraged me from continuing with their program; it is also not unique to this particular nanodegree.

    I've worked on Gatsby sites and Node applications. I'm familiar enough with the node/npm ecosystem to dig through errors and get dependencies up and running. But most people early in their careers or learning are not gonna have a good time dealing with these types of errors, and many won't be able to get past it all. The fact that the very first project they give you can't even be installed because running `npm install` doesn't build the CODE THEY GIVE YOU is a clear sign of how outdated and broken the code they give you is. And as a beginner, you're going to have a very hard time figuring out whether it's something you did wrong, or something they did, or both.

    My recommendation? Spend $60-$100 on the topic you want to learn - this should be enough for 2-3 books and 2-3 Udemy courses. There will be a lot of overlap, but that's good for reinforcing what you're learning, and when you're bored with one (or want to see how another resource explains a similar topic, or you simply want to be exposed to a different teaching style) you can switch to another, and you'll get through most of them in a couple of months. You'll get far more for far less than with Udacity's tracks.

    TLDR; Udacity's business model has them juggling too many balls in the air and their content is often outdated and buggy, which will considerably increase your frustration as a new learner and programmer. Stick to highly-rated foundational books and highly-rated courses on Udemy.

    [Java] JUnit tests fail to run when including certain dependencies using Maven

    Posted: 12 Apr 2021 09:01 PM PDT

    Hello, I am making a Java 11 project that uses another dependency. When I try to write JUnit 5 tests for the project, the tests fail to run due to this error:

    org.junit.platform.commons.JUnitException: TestEngine with ID 'junit-vintage' failed to discover tests ... Caused by: org.junit.platform.commons.JUnitException: Unsupported version of junit:junit: 3.8.2. Please upgrade to version 4.12 or later.

    I was able to isolate the problem in the pom.xml file I'm using (this is a Maven project being written on IntelliJ IDEA 2021.1). Here is a link to the pom.xml file. The problem lies in the com.googlecode.soundlibs dependency. If I include it, JUnit cannot find my tests and runs into the error. If I comment it out, JUnit runs its tests. I used these two files to isolate the problem:

    src/main/java/com/example/project/Calculator.java

    package com.example.project; public class Calculator { public int add(int a, int b) { return a + b; } }

    And src/test/java/com/example/project/CalculatorTests.java linked here. Does anyone know of a solution to this problem?

    Does anybody else get tired when studying?

    Posted: 12 Apr 2021 11:37 AM PDT

    I'm going through python crash course right now. I get really exhausted and feel like I need a nap after every chapter. I want to study more but I'm just tired. Just been doing one chapter a day for now, would like to do more

    Edit cus I didn't just make this post to be a crybaby, what can I do besides caffeine to help with this? I'm brand new. Does this go away with time?

    Any good resources on the history of programming?

    Posted: 12 Apr 2021 06:15 PM PDT

    I'm looking for books or videos that explain of how programming and computation were developed in a reader-friendly way. I know people usually prefer to focus on the technical aspects, but I also need to know how things came to be the way they are today to be able to grasp them. I've already read Code by Charles Petzold (which I highly recommend) and watched the Crash Course Computer Science (both suggestions were made in this subreddit some months ago btw, and I'm very grateful) and want something that goes a little more in depth, specially materials that deal with the history of OS's. Thanks in advance.

    Dreaming about programming

    Posted: 12 Apr 2021 02:42 PM PDT

    Random, but is it normal to dream about coding or tech concepts in general? This happens from time to time especially during a project I have a hard time figuring out or just randomly

    Like just now, I'm trying to understand socket programming and I don't know if this is normal to dream about it

    Advice for my daughter

    Posted: 12 Apr 2021 05:09 AM PDT

    Hi,

    I'm a developer but when it comes to teaching I suck so hard. Recently I bought a pc for my 6 years old daughter for programming or at least wanted to make a start somewhere. What websites or application you would recommend to use during this beginning process ?

    I tried scratch 3 but it's not enough alone. I want to make this learning process a bit more fun than I could.

    Thanks

    EDIT: I had to make an edit. No I'm not forcing her, in fact she is really into it, always watches me when coding and asking questions. Thank you very much for all the answers, I really appreciate it and it helped me a lot.

    What could I develop together with my 3d artist friend?

    Posted: 12 Apr 2021 09:01 PM PDT

    I'm mostly looking for insight here, a good friend of mine is pursuing the career of 3d modeling and I'm pursuing the pure programmer career. It'd be really cool if we could team up to develop some project together,something that one day could become professional, however I can't think of anything other than I developing a 3d software and him testing it, so I'm looking for some different ideas maybe.

    Thanks in advance.

    My rock paper scissors script keeps returning a tie (Javascript)

    Posted: 13 Apr 2021 12:14 AM PDT

    Hello,

    I recently started working through the Odin project, and I'm at the first assignment where I have to create a simple rock paper scissors game in Javascript. I'm trying to put down the basics first before expanding on this, and I know it's probably nothing much, but I've gotten a bit stuck--This code only keeps on returning "tie"--Can someone point me in the right direction?

    function computerPlay() { const options = ["rock", "paper", "scissors"] const choice = options[Math.floor(Math.random() * options.length)]; return choice; } let playerSelection = 'rock'; let computerSelection = computerPlay(); function playRound(computerSelection, playerSelection) { if ((playerSelection == 'rock' && computerSelection == 'scissors') || (playerSelection == 'scissors' && computerSelection == 'paper') || (playerSelection == 'paper' && computerSelection == 'rock')) { return 'you win!'; } else if (playerSelection == computerSelection) { return 'tie!'; } else { return 'computer wins!'; } } console.log(playRound()); console.log(playRound()); console.log(playRound());

    Am I supposed to be overwhelmed at my coding bootcamp?

    Posted: 12 Apr 2021 08:20 PM PDT

    I'm part of a five month part-time full-stack coding bootcamp (Zuitt, for those from the Philippines) that I do after work. I was able to keep up at first for CSS and HTML but once we got to Javascript I got overwhelmed at I'm barely processing it as we moved onto MongoDB, Express, React and NextJS.

    I find myself being able to do simple things that I learned but I'm completely lost at the more complex things especially pathing in Back-End.

    Are bootcamps made to make you feel overwhelmed and clueless? Or am I just not handling it well/not predisposed to coding?

    How to structure a new project?

    Posted: 13 Apr 2021 12:04 AM PDT

    I want to begin on a Node.js project I've been planning for a month, but I keep getting stuck on structuring all the folders and files to begin with.

    What folders should I have and what files should I put in them?

    Should I save functions I use often in separate files?

    Please tell me how to get started with the project so that it is organised, structured and modular, I need help with it.

    Mechanical/Physics Major - Learn Julia or Python/C++ first?

    Posted: 12 Apr 2021 08:13 PM PDT

    Hi all,

    To expand on the title more, I "know" C and MatLab to a slight extent. My programming knowledge is just, "do this problem however, make it spit out the correct answer formatted correctly".

    So I don't actually know how to program "good" code, which is why I'm wondering what to focus my efforts even more to, I know writing good/efficient code is better for Julia considering that's how to eek out performance from Julia.

    It's looking more like I will join a research group that focuses in Computational Fluid Dynamics, which uses OpenFOAM (C++ toolbox).

    I'm not sure which one to learn how to code first, let alone how to make efficient code that performs well.

    So what do you all think I should learn first?

    I also already have all the resources to begin learning these, just don't know which one is a good language to get a good handle on.

    What is the best website to study programming FREE

    Posted: 12 Apr 2021 11:46 PM PDT

    One of the best reasons I want to study programming is because it is a creative and enjoyable problem-solving activity. Studying programming languages will help me be better at my job, make more money, and be a happier, more fulfilled, and more informed citizen.

    Any way to convert this animated wave to curves instead of lines (Javascript HTMLcanvas)?

    Posted: 12 Apr 2021 11:37 PM PDT

    const canvas = document.querySelector("#canvas") const ctx = canvas.getContext('2d') var height = canvas.height var width = canvas.width const Random = (low , high) => { return Math.random() * (high - low) + low } class Point { constructor (x, height) { this.height = Random(Math.floor(height / 2), height) this.min = Random(0, Math.floor(height / 2)) this.x = x this.y = Random(10, this.height) this.offset = 0.05 this.cur = this.y } update () { this.cur += this.offset this.y = this.min + Math.abs(Math.sin(this.cur) * (this.height - this.min)) } } const points = [] for (var i = 0; i <= 10; i++) { points.push(new Point(Math.floor(width * i / 10), height)) } const draw = () => { ctx.clearRect(0, 0, width, height); ctx.beginPath() ctx.moveTo(points[0].x, points[0].y) for (var i = 0; i < points.length - 1; i++) { ctx.lineTo(Math.floor(points[i].x), Math.floor(points[i].y), Math.floor(points[i + 1].x), Math.floor(points[i + 1].y)) } for (var i = 0; i < points.length; i++) { points[i].update() } ctx.lineTo(width, height) ctx.lineTo(0, height) ctx.fill() } const animate = () => { draw() window.requestAnimationFrame(animate) } animate()

    To run this a canvas with id "canvas" is needed.

    I need to convet these lines to smooth curves to create a wave like animation.

    I have tried to use ctx.quadraticCurveTo() by calculating the next control point to be on the line created by the current control point and the next anchor point for each curve. It makes a smooth curve but it looks stuttery. So, this code only includes the ctx.lineTo() version.

    Zero and negative Zero JAVA

    Hey guys i got a quick question, why does Java takes 0 and -0 as if it is the same number??

    I made an if statment, if the number was 0 print something else if number is -0 print something else, but Java takes 0 and -0 as the same number so it always returns the first statment

    Integrating my project to kiosk, is it possible?

    Posted: 12 Apr 2021 07:21 PM PDT

    My project is Barcode System with Facial Recognition using python language. The said project is for the record of the employee including the time-in and time-out. Basically, the ID's of the employees has their own barcode.

    This is how my projects works:

    So every time that they need to do their time-in or time-out, they will need to show first their face at the camera. After that, the system will analyze if that person is a legit employee of the company. If the person is confirmed, the system will say "Scan now" it means that the employee may scan their barcode in their IDs. The system will analyze now if that barcode is owned of that employee, it is for the employee to not be able to cheat.

    We want to do it at first in Raspberry Pi 3 model B, but I can't rid the lag there. Unlike in my laptop or pc, it don't have lag. So we want to do it now in kiosk. I'm not familiar with kiosk that is why I am here to ask, is it possible to integrate my project in kiosk?

    Before starting a big personal project, should I read Code a complete 2, and design patterns to make sure I am starting off on the right foot?

    Posted: 12 Apr 2021 04:53 PM PDT

    I have done a couple of small personal projects and have decided that it may be time to move onto something bigger. I realize how detrimental it can be to my future self to have a poorly put together project because I do not know good coding practices. Should I read some books before starting the project so that I can ensure I will not have to do as much refactoring later? Also, any other recommendations for books to read?
