    Free web development bootcamp: Starting Aug 23rd

    Posted: 05 Aug 2021 01:39 AM PDT

    I hope this is ok to put here, I fear it may brush against rules on shameless self promotion, as I'm shameless and this is promoting something I'm silly proud of.

    👋I'm Jess! I'm a former teacher who has worked in tech for a million years and I hate exploitative, high cost programming bootcamps so much. I got so annoyed at them that I made a free web development bootcamp based on freeCodeCamp's Responsive Web Design curriculum (with their permission) and MOOC principles.

    We're starting on Aug 23rd and covering HTML, CSS, CSS Grid, CSS Flexbox, visual design, accessibility and responsive web design principles over the course of 3 months. We're not covering JavaScript in this cohort, but will look to add another cohort if there's demand from learners.

    I expected maybe 50 or 100 learners would want to join me for this course but have had 1700 sign up this week, so I'm going to work on this project full time for the next few months to support as many learners as responsibly as possible. This is completely free, there's no stealth upsell (really, there's nothing to sell, there's literally no way to pay us) and we're measuring our program's success in how many folks we can keep from needing to pay for expensive bootcamps.

    If you wanted to read more or sign up, here's the link. But if any of you have any feedback or suggestions about what more we can do for learners on our course, I would consider it a gift!

    Edit: Y'all, don't give me awards! Save your money and spend it on books or snacks or books about snacks <3

    Is it legal to web scrape from yahoo finance ?

    Posted: 05 Aug 2021 06:31 PM PDT

    I implemented web scraping to get conversion rates between different currencies from yahoo finance in my android application. I strictly use yahoo finance to get conversion rates to convert from CAD to another currency. Also, I do not store the rates anywhere. Is there any implications of doing this ?

    Is it possible to avoid web dev?

    Posted: 05 Aug 2021 10:37 PM PDT

    Every time I look for anything software engineering all I see is web dev stuff. Same goes for resumes, I'm not interested in being a full stack engineer, let alone front end. I know c++ and python, is there any careers that involve these two, maybe even Java? I know data science is a subject but that too doesn't peek my interest. I'm at the point where I need to start preparing for interviews but I really want to avoid doing anything web dev. I'm not that creative and I also don't want to learn HTML & CSS. There's already plenty of amazing front end / full stack engineers out there and I don't want to be another one at the bottom of the pile.

    Do i need to create an API in Nodejs for React to be able to use data from my database?

    Posted: 05 Aug 2021 12:20 PM PDT

    I have only ever done front end development and the youtube videos and tutorials differ on their approaches. Besides creating my server with express and connecting to my database, do i still need to create functions for retrieval and post in the backend, the reason i ask is that in the tutorials i watch those are referred to as API calls.

    ​

    This is very annoying as i am having trouble trying to figure out a way to connect my backend to my frontend.

    ​

    edit. Not sure if this matters, but i am using mongodb

    Friendly feed back

    Posted: 05 Aug 2021 10:41 PM PDT

    Hello Reddit friends,

    Im about to start my first year in college in September as a cs major.. im very passionate about it but I haven't started bcuz i figured i would just start when school starts, which looking back at it now i regret not starting to learn some type of language before school started just to know a little criteria. Im writing this to get some input.. would it be harder because I didn't learn a language before entering or will i be okay? Im fully committing myself for these next couple years to learn and understand how to code. I would love your feed back, thank you.

    Struggling with a react-window rendering challenge

    Posted: 05 Aug 2021 10:05 PM PDT

    I'm trying to build an app where users can swipe up and down to scroll through different YouTube videos. I'm using react-window and react-player and the intersection Observer API for this. I'm using react window because I don't want to have a huge list of YouTube Iframe embeds loading every time (slowing things down) I only want to load one or two in the browser (using windowing) so that the list works quickly.

    I'm finding that I can't get my list of videos to render beyond the first three videos. It just sort of goes white or blank. I also struggle to get the same video to render twice. Not sure what I'm doing wrong here in the setup of the list with react-window.

    My main List component looks like this

    import React, { useState, useEffect } from "react"; import Video from "./Video"; import "./App.css"; import { CircularProgress, Grid, Box, Divider, Grow, ListItem, ListItemIcon, ListItemText, ListSubheader, Typography } from "@material-ui/core"; import { FixedSizeList as List } from "react-window"; import useWindowDimensions from "./useWindowDimensions"; function App() { const [videos, setVideos] = useState([]); const [isLoading, setIsLoading] = useState(true); const { height, width } = useWindowDimensions(); useEffect(() => { fetch(`https://sheets.googleapis.com/v4/spreadsheets/1Ykwd4zmQsPWxwQ7UaSGpkLKLaSE1By5e_WfhQgR7vXM/values:batchGet?ranges=export2&majorDimension=ROWS&key=AIzaSyC1XWLfbg_9cbaq6dw-eFROFVDpfp2XhxE`, { method: "GET", headers: { Accept: "application/json", }, }) .then((resp) => resp.json()) .then((data) => reformatRows(data.valueRanges[0].values)); }, []); function reformatRows(data) { let rows = []; for (var i = 1; i < data.length; i++) { var rowObject = {}; for (var j = 0; j < data[i].length; j++) { rowObject[data[0][j]] = data[i][j]; } rows.push(rowObject); } // console.log(rows) setVideos(rows); setIsLoading(false); } const renderRow = ({ data, index, style }) => { const { url, channel, description, song, likes, messages, shares } = data[index]; return <Video url={url} channel={channel} song={song} likes={likes} messages={messages} description={description} shares={shares} height={height} width={width} />; }; // this works without react-window but is very slow // return ( // <div className="app"> // <div className="app__videos" style={{height:height, width:width}}> // {videos.map( // ({ url, channel, description, song, likes, messages, shares }) => ( // <Video // url={url} // height={height} // width={width} // channel={channel} // song={song} // likes={likes} // messages={messages} // description={description} // shares={shares} // /> // ) // )} // </div> // </div> // ); // this loads but doesn't work if (isLoading) { return <CircularProgress style={{ margin: "0 auto" }} />; } else { return ( <div className='app'> <List height={height} width={width} itemSize={height} itemData={videos} itemCount={videos.length + 1} className='app__videos'> {renderRow} </List> </div> ); } } export default App;

    The code can be found in this sandbox (https://codesandbox.io/s/inspiring-forest-hu1oj?file=/src/App.js:0-2707&resolutionWidth=454&resolutionHeight=675) and the application demo can be found in this URL (https://csb-hu1oj.netlify.app/). To demo the app you need to use the responsive simulator within Chrome or Firefox in order to make it seem like mobile and have the swiping action work.

    Help understanding how to go about game idea

    Posted: 06 Aug 2021 12:37 AM PDT

    Hey all,

    I've been through a coding bootcamp, and taken numerous online courses on programming. I probably know swift the best but I've been dabbling in c# and unity lately. While I was at the coding bootcamp, I had an idea for a kind of RTS game that might work on mobile but I can't wrap my head around how to program a single core concept of it.

    The idea was that the world would be generated as a series of layered flat planes where the middle layer of the world part is literally like if you took a color gradient layer. The top starting layer would all be white and the bottom layer would all be black. The resources of the game are the colors you "dig up" as you dig downwards. So maybe in one base it starts out white and as you dig down, it slowly changes through green to black but in the other players base it would go through red to black. But if you removed the top layers 1 at a time, the whole map would shift from white through a vibrant multicolored gradient and down to black. The question is, how would I go about generating a playable world like this? I could just generate a color gradient then copy that layer and slowly change the brightness of it in either direction and layer maybe 1023 different layers but if a player starts digging, then holes would begin to appear in the different gradient layers and that would make it very complicated.

    Having written this out, it probably isn't a great explanation of the idea, but I hope it gets across what I'm wanting to attempt to do.

    Thank you kindly

    Fullstack Development vs Data Engineering

    Posted: 06 Aug 2021 12:29 AM PDT

    I joined a company as a Javascript React/Node Developer. I spent the last year studying these technologies to be able to get a job in the industry and I finally made it to a Junior/Mid position. I was hired for a Data Department where they had the idea of building an internal tool with Node and React, and now the project is paused because our Senior Dev is gone. Since then, I've been working with the Data Engineers in different tasks that were not in my scope before: Data processing, data pipelines, python, etc. It is something i find interesting and I also have very good mentors in the team who are teaching me a lot of stuff, so now I have this question: - Having spent a good amount of time in learning JS/React/Node, would it make sense to switch now to Data Engineering? - Considering that I like both fields, which of them might have better opportunities in the market? - Is there a field that combines these two skillsets that I might want to explore? Thanks for your opinions! Cheers

    Is there any platform to watch people programming live?

    Posted: 05 Aug 2021 09:41 AM PDT

    twitch has really few streams and not configured for programming and replit has nothing like table that show who are live and streaming now(you can just open room and share its link).

    So I couldn't find any platform like I want(Configured for programming, have public streams).

    Some questions for blockchain programmers

    Posted: 05 Aug 2021 08:04 PM PDT

    Hey guys, I've been following blockchain projects for years now, and in the last years studied them to a deeper level..

    Recently I decided I want to peruse a career in this field as a developer, but im having some hard times finding anyone in the same field.

    I watched videos and read articles on the subject and manage to collect some questions I would love an answer on.

    -How important web development skills are, should I put some time and effort into becoming a fullstack before learning solidity? Or the fundamentals of web enough?

    -besides solidity are there any other popular languages I need to consider?

    -if my end goal is to develop/work on a block chain rather than developing dapps, do I need to do anything in particular/learn anything/aim for a specific job etc.

    I really hope some of you could give me some answers or in genera share with me your experiences with blockchain, I'm really enthusiastic :)

    Generating new pages upon user data input

    Posted: 05 Aug 2021 11:41 PM PDT

    I'm doing a project as a frontend where I'm making some sort of platform where people can create a notice page (which will be added to the notice board).

    I'll create an html page for the notice board where all the notices registered by users will be listed. But how am I supposed to make each notice page that a user uploads? I'm thinking after the user's input data (ex: title, details, etc.) are sent to the server, a new notice page with that data should be generated and uploaded. Also, if the list of notices on the notice board are each an anchor tag, how would I link the href?

    I'm using HTML, CSS, Vanilla JS. And the backend developer is using Java (Spring Boot).

    I've been told I should use a template engine and that this all needs to happen on the server. But can someone explain to me in more detail?

    I need help wrapping my head around this concept.

    Where and how to learn ONLY for competitive programming?

    Posted: 05 Aug 2021 11:24 PM PDT

    Hello! I am looking to take a competition in computing in half a year but I have very limited understanding in programming. Theres A LOT of online resources out there but I was wondering if there is any ONLY dedicated to the stuff needed for competitive programming, which would excludes stuff like GUI since im limited on time. specifically, I am planning to learning python since I already have some basic understandings of it (i could switch to c++ tbh since i heard that was easier)

    the competition is high school level and contains at hardest ioi level questions so if anyone could point out what specifically I need to learn before jumping into doing contest questions that would be great
    edit: sorry if post is a bit close to faq, i couldnt find info on this topic :(

    Youtube videos

    Posted: 05 Aug 2021 07:25 PM PDT

    To anyone starting out this journey, you will see a lot of YouTube videos saying "Learn (language) in X amount of time". Understand that this is not so much a learning video and rather a "know about" video.

    You can't learn a language in 1 or 2 or 3 or 4 or even 20 hours. It's merely a long ass info session about the topic.

    I'm writing this post because a lot of people believe they will actually learn a language in the said amount of time and know how to solve leetcode problems or build a project which can lead to disappointment because you should have "learnt" it.

    You learn when you are doing tasks they give you or projects by using Google and other materials. You won't retain 95% of the information from a video.

    So don't stress and understand that it is just a "know about" video. Take your time, grasp concepts by doing and not just videos or reading.

    If you have a large number of users is it better to split them into different databases to query?

    Posted: 05 Aug 2021 11:04 PM PDT

    If you have a really high number of users would it be better to have for example 5 different databases or collections that hold the data for 10 million users each. I.e. 50 million total. And then an intermediary determines which database to query. Or is it okay to just hold it all in one collection/db.

    I feel like I am wasting my time learning CSS

    Posted: 05 Aug 2021 04:47 AM PDT

    Hi guys,

    I have been learning front end stuff for about 6 months. I finished the javscript.info course and I think I have gotten fairly good with this language. I also know VUE , however there is still a lot to practice with both. The thing I am mainly concerned about is, that I spend the most time playing with CSS. For some reason I really like it, and I understand most of the important stuff like boxmodel, grid, flexbox, positioning etc. as well as preprocessors. I kind of struggled with structuring so I did some research regarding object oriented CSS, BEM, SMACSS etc. and kind realized that there is atomic css and things like Tailwind which turn the whole thing around. Also read some reddit posts which kind of said that today, it is all about frameworks, and things like VUE are pushing the core CSS out. I would like to be job ready in a few months, whoever I am also a college student of economics and sometimes struggle with anxiety, so I not always have so much time to invest and when I do I am afraid I am just wasting time with css (or I should say SCSS because that is the preprocessor I use daily and understand well). I would like to hear your opinions thanks.

    Which Udemy MERN stack course is the best?

    Posted: 05 Aug 2021 01:10 PM PDT

    I own the course for React from Max Sch. and the Node course from Andrew Mead, but I'm looking for a complete MERN course, now.

    My goal is to build more projects to add to my portfolio.

    I like Andrew's delivery, and I kind of struggle to pay attention to Max.

    I thought his React course was too basic beacuse, by the end of the app, you could only build a hamburger. I mean literally, a visual representation of a hamburger.

    Colt Steele = the best for delivery, but he doesn't teach/know MERN as far as I know.

    Iv'e heard good things about Brad Traversy.

    Bulk import XML documents in the Microsoft Office schema to Excel

    Posted: 05 Aug 2021 09:36 PM PDT

    I'm tryng to import log files which are in the MS Office XML schema so that I can convert them to CSV (BrightSign player logs specifically, if anyone is familiar with those). This is easily done one-by-one, but every time I try to import multiple XML files it opens as separate workbooks. Is there a way to bulk import all the files into one sheet, under one header (header and schema is identical for all files) so that I can export a single CSV?

    My apologies if this is not appropriate for this sub.
