    Shifting from windows to linux OS

    Posted: 06 Sep 2021 05:58 AM PDT

    Hi! I'm a python developer. I've used windows all my life for gaming, multimedia, programming and everything. But now I want to shift to linux OS. So basically I need help selecting an OS and need some resources that can help me become a "linux pro". Any advice would be greatly appreciated. Thanks.

    Free Programming Lessons

    Posted: 06 Sep 2021 07:44 AM PDT

    Hey everyone,

    I've been a software developer for about 6 years now and i love teaching. I have taught or rather coached programming to more than 100 hundred students over the last past few years.

    I moved to the States not so long ago and ever since i started my full time job here I've been thinking of teaching programming again. Ideally I'd like to teach beginners and intermediate folks separately - focusing on fundamentals for beginners while maybe building a full blown app with dev ops and what not for intermediates. Given the pandemic and delta variant I'd like to do it virtually but hit me up if you'd be interested.

    I've always seen programming as a welcoming discipline and this is my way if giving back!

    Cheers!

    PS: I'd like to use Golang as the language of choice!

    Update: I have created a discord server - everyone interested please join it. I will keep posting updates over here. I am fairly new to discord and don't completely understand how to use it. Any help is appreciated. See you guys there

    https://discord.gg/HaY9ttDX

    ​

    Update: Here's the first Lesson plan - it is incomplete but it should give you a brief idea of what I intend to cover. Please reach out if you have any questions. Thanks!

    Suggestions for how to make coding fun for new members of programming club

    Posted: 06 Sep 2021 09:13 PM PDT

    In a few weeks, a friend and I will be taking over our high school's programming club. Usually what happens is that a lot of people join, but then a good chunk of them leave out of disinterest, leaving only the more experienced programmers. This year, I want to change things up and I was hoping to get some tips on how to keep people interested. I feel like the main problem has been balancing getting people to learn to program while also keeping them engaged through projects and such.

    Any suggestions on how to make the club more engaging for new members would be much appreciated.

    Just finished a project that I was really struggling on. I feel excited to start the next one.

    Posted: 06 Sep 2021 11:27 PM PDT

    I made a post not too long about how I was struggling and how I felt lost when solving issues in a todo list. I finally found out how to solve the problem and everything started clicking. Thank you to everyone who replied to the last post with advice.

    I am learning C right now and wanted to know when I should make the transition to a higher level

    Posted: 06 Sep 2021 11:14 PM PDT

    I purchased one of the books (Head First C) shown under the basic section here https://stackoverflow.com/questions/562303/the-definitive-c-book-guide-and-list and wanted to know when I should make the jump to intermediate? Do you think just reading one book will be good enough or should I at least try to read one or two others to build up my fundamentals better?

    I want to help a beginner learn HTML/CSS/JS

    Posted: 06 Sep 2021 03:24 AM PDT

    Hey,

    I have someone mentoring me into advance concepts of JS and react and I thought I should try to help some beginners at the same time to give something back to the community, so if you're a beginner and want some help DM me with what you have already covered and what you want to learn and your time zone.

    Thanks :)

    Where to learn terminology and stay updated about tech

    Posted: 06 Sep 2021 06:45 PM PDT

    I've decided to take a year to learn how to program. I spend a couple hours a day working with python now. When I can't actually program, I like to browse subreddits like this to learn more or follow discussions even if they are way over my head.

    I've come to realize how big tech is and how easy it is to get lost. I kind of know the path I want to take: 1. Python to get my head around programming concepts and be able to automate tasks. 2. The Odin Project to delve into html, CSS, JavaScript, Git. 3. Learn some database, server side stuff as well so I am comfortable interacting with it. 4. Get comfortable with Linux and command line.

    My question is, where can I go to read about tech from a beginner level so I can discuss and think about it. Right now I'm just in my problem solving bubble trying to code, but that is pretty far removed from the big picture. Maybe some tech blogs or youtubers that break things down and talk about where things are headed?

    I'm working on a Twitter react clone and was getting a bit frustrated that the code wasn't doing what I told it to do. For an hour it wasn't loading anything. Eventually, I decided to back track to the working version and notice the problem. I reverted the code to the old state, yet never changed the main, App.js file, and it some how worked. That's when I noticed

    import Tweets from './Tweet'

    I was working on Tweet **S** .js and I never imported it.

    It helped that I took a mini break to come back to this code. I'm a bit tilted that I figured out the solution this late in the night.

    I just wanted to share this, since I have no else that I can say 'I fixed the problem I created.'

    React Hook useEffect has a missing dependency warning and how to deal with it

    Posted: 06 Sep 2021 11:47 PM PDT

    Hi everyone,

    I've noticed few warnings in my code because of missing dependencies in useEffect, but I do not need to run the function when those dependencies change (or they won't change). I do have quite a few useEffects with [] dependency, so it would only run on component load and that is fine with me.

    I do not want to lie to React and provide all non-braking dependencies which would not do any good. Or workaround in other cases.

    What is the right way to solve this problem? Would writing code to avoid these warnings would result in better code? Any good source regarding this?

    Thanks!

    Database as code or manual database migration files?

    Posted: 06 Sep 2021 11:45 PM PDT

    I'm starting a new project (web application with REST API) and am wondering what is a better way of managing my database. I have experience with EF Core which does the migrations from code but am wondering is there benefit of writing migration scripts manually (.sql files for both up and down migrations).

    What are the benefits of manually writing migration files? Is it worth doing or is database as code enough? The application will only have relationships such as many-to-many, etc.

    Anxiety/ Imposter Syndrome

    Posted: 06 Sep 2021 06:18 PM PDT

    Im currently a student learning software development. I get strong anxiety before starting any of my projects thinking I don't know how to begin or how I will get this done. Although when I do start projects I feel a bit more calm and I start feeling like just maybe I can do it but there is always a time when Im stuck for hours and I feel like I'll never be good enough to get a job in this field. How do I overcome this chain holding me down? How have you guys overcome it?

    I need some guidance

    Posted: 06 Sep 2021 11:11 PM PDT

    I'm taking up learning programming for about the third or fourth time, but now I have a product that I'd like to create that is really fueling the fire and I would just like some guidance so that I'm not wasting my time digging into something that won't actually help.

    I would like to know which language would be best to build a web app, I've started learning HTML/CSS and starting to get fairly comfortable and most of the tutorials seem to point toward javascript. The app that I want to build will basically take a users information and send them either a text or email when certain weather-related phenomena happen in their area based on their location, so there will have to be some database in the backend I assume and some way to reference like a weather website.

    I would also like to potentially be able to transfer to an actual mobile app (apple and android) at some point (not sure this is possible) though I think a web app is the best MVP to get things moving and ensure everything can actually work.

    There are so many languages to choose from Javascript, Python, Java, C++, and i've also read that it may require learning multiple, so I'm just reaching out to get some guidance and thank you, anyone, for your reply I greatly appreciate it.

    Is there a way to get the geojson data for European municipalities (perhaps directly out of google maps)?

    Posted: 06 Sep 2021 10:59 PM PDT

    Hi all,

    so I am currently programming in Python and want to make a Choropleth map using folium (example instructions for this kind of map):

    https://towardsdatascience.com/choropleth-maps-with-folium-1a5b8bcdd392

    Now in order to make such a map I need a geojson file which applies a layer to my map so these layers can then be coloured. Now originally when I was testing this feature I found that this github repository had quite some resources I could make use of:

    https://github.com/codeforgermany/click_that_hood/tree/master/public/data

    But the problem is that there a lot of countries don't have a municipal split but rather a provincial which is a too high level split for me to make it useful. But now looking at google maps I see that the municipalities are already there (example of a random Belgian commune):

    https://imgur.com/jRgfKZz

    Is there perhaps a way to get this data directly out of google maps or alternatively is there a folium functionality or perhaps another add-on for Python that could give me this functionality?

    How to build a backend REST API that allows to be consumed only by my website?

    Posted: 06 Sep 2021 10:34 PM PDT

    I have a react app which is a website. I want to add some functionality to it so I decided I could build a node JS rest api that exposes the data I want. The thing is that I only want this data to be available to my website only, so no other client can consume my API.

    How can I do this?

    Edit: the website is public for everyone, not only in my localhost.

    How to design an API for updating a single field on an object?

    Posted: 06 Sep 2021 05:58 AM PDT

    What's the most RESTful way of updating a single field on a large object?

    So suppose I have a user object with a membershipType field. This field can have multiple values represented by an enum.

    Would this work?

    PATCH user/{userId}/membership-type body: new-value

    or would I put the new value in an object? If I do it this way do I have to create a load of DTOs for every possible field that can be updated (I'm using Spring Boot if it makes a difference)?

    PATCH user/{userId} body: { membershipType: "new-value" }

    Finished my first program with lists, how did I do?

    Posted: 06 Sep 2021 06:00 PM PDT

    Hey guys I just finished my first program involving lists. I wanted to see how I did. The program is a contact book that can save to CSV. I think it works well (although saving to CSV can be janky) but I wanted to hear some feedback from you guys. Well here you go:

    # This creates 3 empty lists that will be used, if a CSV file is imported these lists will be overwritten. This also imports CSV import csv import sys contact_names = ["","","","","","","","","","","","","","","","","","","",""] contact_numbers = ["","","","","","","","","","","","","","","","","","","",""] contact_email = ["","","","","","","","","","","","","","","","","","","",""] handler_list = ["","","","","","","","","","","","","","","","","","","",""] selection = "" selection2 = "" selection3 = "" # The 'main' function exists so other parts of the program can return to it so the user can make another selection, it has to be at the top to reduce errors def main(): global selection print ("Would you like to (V)iew contacts, (C)reate contacts, (D)elete contacts, (E)dit contacts, (I)mport CSV or (EX)it?") #This is a while loop that 'traps' the user until they make a valid selection (V, C, E, I or EX) while (selection != "V") and (selection != "C") and (selection != "E") and (selection != "EX") and (selection != "D") and (selection != "I"): selection = input() if (selection != "V") and (selection != "C") and (selection != "E") and (selection != "EX") and (selection != "D") and (selection != "I"): print ("Incorrect Entry!

    What do entry-level back-end programmers in your company do?

    Posted: 06 Sep 2021 02:13 PM PDT

    Hi guys, I'm starting my first job soon, and I'm probably going to be focusing on the back-end. The manager said he'll drop me in deep waters on my first day and I'm a bit worried, I have no idea what to expect, and I'm more on the anxious side of the spectrum... So I'd like to know, what do entry-level programmers in your company do in their first days? Thanks in advance :)

    C++ or JavaScript, which one to focus on first?, Positive and negative side of each.

    Posted: 06 Sep 2021 05:17 PM PDT

    I will start a course in my country and after the first semester it will use C/C++ as a language, I will need an internship, so I thought about JS, but I'm afraid of having difficulty understanding concepts like algorithms, memory, data structure since people say that C++ would be easier to understand these concepts.

    Should I focus on C++ for 6 months and then move to JS, HTML, CSS ?

    will it be easier with programming in general if I start with C++ or does it make no difference?
