    First job as a front-end junior!!

    Posted: 30 Jul 2019 09:13 AM PDT

    Hi all, got my first job offer today for a front end junior role! So please as it's exactly what I've been looking and working for and its paid off.

    Plenty more hard work and learning from here on!

    Edit: I studied for about 2-3 hours a day for 7-8 months. I was quite lucky as I was travelling Australia whilst learning it so have fun at the same time. I didn't have a study schedule I just did it 5 days a week as I burned out doing it 7 days.

    Update: Real Fake Startup

    Posted: 30 Jul 2019 07:17 PM PDT

    I promised everyone I would post an update so here it goes.

    The other day during a period of fatigue induced confusion I posted an offer to mentor group projects for people trying to get real-world experience in a mock business scenario.

    Original Post: https://www.reddit.com/r/learnprogramming/comments/chigg1/offering_realworld_experience_for_beginners/

    I underestimated the reach of this sub and there are now close to 500 responses. Obviously it is not going to be effective for me to mentor all those people at once, so I have set up a queue.

    Working in batches of 25, for a period of 4-6 weeks I intend to work through the list. I have recruited a mock COO and I am also been helped by my Assistant to the Regional Manager, another volunteer.

    Currently we have on-boarded the first group and are going through ideation and group forming then we will move on to the design and build phase.

    If people can wait, you will get an opportunity.

    In the mean time I have set up this app for people to continue to apply and to check their status in the queue.

    https://real-fake-startup.herokuapp.com/

    Note: If you have not entered your full Discord name, go ahead and resubmit, I will use the EARLIEST contact to determine your position in the queue.

    Second note: If you are a Senior or Architect Level developer and would like to help please note that on the "Why are you interested?" section of the sign up form.

    Freely available practical math books for programmers?

    Posted: 30 Jul 2019 11:37 AM PDT

    So, inspired by a post I saw yesterday on this sub, I realized that there are soo many things I cannot do as a programmer right now because I do not have a good math foundation. I cannot truly get into game dev, vr/at, ML etc.. because I do not have the required background. I have tried to copy some of the formulas for ML and realized that the symbols used are foreign to me.

    So, I want to know if there are books available online from programmer perspectives that can form a good foundation on which I can build upon

    Can you add an additional “process” or customize the default ASP.NET Core Registration feature to first authenticate credentials via login from a different project before saving other details to db?

    Posted: 31 Jul 2019 12:15 AM PDT

    To start things off, I'm not the Initial developer of this project, and I'm almost completely new to asp.net core and entity framework (Java and Spring before).

    Situation

    So my teammate created a project mostly based on this guide by microsoft. It's as simple as using the default AspNetUser Identity System. So from what I understand, no need to create an endpoint for Registration and get the registration details and save them somewhere - AspNet handles it all.

    But the problem is now we have an additional "demand" for our project.

    There's this "parent" project that another team is working on. It has it's own User system. Now what we're asked to do is:

    1. When registering for child project, provide username and password credentials that you also use for parent project login.
    2. Only Register the user IF the username and password exists.
    3. If the user exists, also save the employeeId provided by the parent project into a column in table AspNetUser.
    4. When logging in child project, authenticate via the parent project instead. If user exists, it will return a token that we'll be using for requests. We'll be saving the token somewhere else (Planning to create a custom claims http filter thing)

    Is there anyway AspNetCore provides to allow adding additional steps/processes in registration that'd allow us to first verify the user via the parent project login? Or are we better off just creating our own user system without using the default one provided by AspNetCore (yeah security concerns etc.)

    How do I set up a web server to handle HTTP POST requests

    Posted: 31 Jul 2019 12:04 AM PDT

    A third-party voice API provider requires that I set up a callback url to respond to http post requests. I'm confused as to how this works.

    I assume I'm supposed to set up a web server (any suggestions which one?). Once I have a web server set up, say Apache, will I then configure Apache to respond to the http post requests? Or will this be done by a separate application running on the web server. Please help me understand how this works or what I need to read up on.

    Choosing a bootcamp Style online course

    Posted: 30 Jul 2019 08:07 PM PDT

    Hi LearnProgramming,

    Mainly due to VISA rules I will have 1½ year where I am unable to work. Perfect time to start a new-ish career.

    I want to learn to be a programmer. Full Stack. Not front end or backend only.

    I am limited by price though, and want to stick within 300-400 USD /Month.

    I am currently between OpenClassroom and Udacity Nanodegree

    OpenClassroom:

    https://openclassrooms.com/en/paths/104-full-stack-developer

    300USD / month

    Bachelor Degree

    12 months:

    Udacity Nanodegree

    https://www.udacity.com/course/full-stack-web-developer-nanodegree--nd004

    400USD/Month

    Diploma, but backed by Google

    6 months

    My end goal is to be a programmer. Not someone who totally knows React, or CSS..or Ruby on Rails ...a programmer. I want to learn enough so that if I need to pick up another language, I know enough to be able to do that. I want to learn to plan a program - write good code- write unitTests, keep SOLID and DRY and other cool acronyms.

    Which option will help me get there (or get far)

    Have I missed a good option ?

    TL:DR:

    OpenClassroom or Udacity ?

    I want to learn everything at the same time; I don’t know what to do next.

    Posted: 30 Jul 2019 05:06 PM PDT

    Hey, I hope you're doing well

    Just finished CS50: Intro to CS and it was an awesome course! Now I don't know what to do next.

    There are so many job titles and so many paths that I'm confused. And everything seems Web Dev related! I'm scared I will have to resort to FCC and The Odin Project because I truly hate anything related to designing and HTML and CSS.

    What's the difference between DevOps, Software Engineer, Software Developer, etc? They also have to do stuff related with web development?

    My goal is to create software and mobile applications, and maybe game development as a hobby. I have so many ideas for apps I want to develop for fun such as a Reddit client, Instagram clone, etc. that could help my portfolio. (And I don't mind porting those apps to a web version, I actually want to do that, but is designing a must?)

    Thing is, should I learn more about CS with MIT courses and OSSU, or I can start getting more high level and creating useful applications right now? (Keeping in mind I pretend to apply for jobs in approx. 2 years)

    Thanks and sorry for the long post, have a good day

    What steps should I take as a junior in high school to be better prepared for a career as a software engineer/developer?

    Posted: 30 Jul 2019 07:11 PM PDT

    I started the process of learning Java with a computer science Pre-AP course in my freshman year. We ended on constructors (I think that's what it's called) and using methods from different classes.

    Anyways, school is starting again in a couple weeks and I wanted to know if there was more that I should be doing. I have AP Computer Science in my schedule (and I know we are learning java again)

    Should I learn Java outside of school? Are there other languages I should be focusing on?

    (Sorry if this breaks the rules I didn't know where else to post this)

    I'd like to build a tool that can trace the camera motion in a video game, specifically Counter Strike, in order to hopefully build an aimbot auditing tool. How do I go about that?

    Posted: 30 Jul 2019 04:52 PM PDT

    In my day job I am a SWE. My question isn't so much about coding but rather about how to design this system.

    I'd like to build a system that can analyze replays, ideally on twitch, that can trace a player's camera movement while they play csgo. I'm interested in seeing what their aim looks like. Specifically, how quickly do they snap to? How straight is their aim? How abrupt is their acceleration and deceleration?

    Hopefully this data would let someone audit a replay and help determine if a player was using an aim bot or aim key.

    How can I build a system that will be able to extract camera movements like that?

    I flunked a job question in a job interview, asked to write a short function/algorithm. What is the solution I missed?

    Posted: 30 Jul 2019 11:26 AM PDT

    I had an interview where they asked me to whiteboard what sounded like a fairly simple program - but i totally came stuck on it.

    Picture an old mobile phone, where each number key has letters assigned to it: 1=ABC, 2=DEF, 3=GHI 4=JKL 5=MNO 6=PQR 7=STU 8=VWX 9=YZ 0=space

    And you are given a dictionry of words, example [] = { bat, cat, ball, catologue },

    So you can type a word by keying in 1 number to represent a letter. The program should read the dictionary of words and return the matches

    So you key in 1,1,7 as an example, it should return bat, cat (exact matches) and catalogue (first 3 characters match).

    I kind of came up with a solution by just looping through and creating every possible string from the combination of numbers (27 i guess, for a 3 digit number, 81 for a 4-digit, increasing fast) but it was pretty horrible.

    What's a better way of going about it?

    I'm sure there is an efficient way using graphs or trees, but i've just never really worked with many non-linear data structures before so I had no idea how to go about modelling it.

    I've been programming professionally for years but almost never have to do something akin to this.

    string[] GetWords(string[] wordDictionary, int[] numbersKeyed) { //crashed }

    Tips for a semi-beginner programming student

    Posted: 30 Jul 2019 06:52 PM PDT

    Hey there Redditors, as the post title suggests I'm an beginner at programming and want to better myself by learning some theory and doing some projects as well. Some background info, I've taken high school comp sci and learned some java[learned up till time complexitys and making programs efficient by space reduction and looking for smaller time complexity solutions]. I've learned a couple of algorithms such as bubble sort, linear search, merge sort and etc.

    All I want is advice to further my learning and become a better programmer in the near future.

    Thanks for reading and have a nice day!

    Coach me in a simple C++ program?

    Posted: 30 Jul 2019 06:13 PM PDT

    I have a bit of experience already, but I'm a carpenter by trade and I'm looking to make an extremely simple text based program to figure out certain measurements. The problem I'm not good at solving on my own is doing math with fractions and having the answers be fractions. If someone is interested in walking me through a few steps, please just send a pm. I'm able to chat through Reddit or discord.

    Do you have to explicitly write a destructor in your class? Or is it automatically/implicitly called?

    Posted: 30 Jul 2019 09:55 PM PDT

    Creating some basic classes for fun right now and am not sure if I should bother creating a destructor since I'm not using any dynamic memory or anything similar of the sort.

    Feeling overwhelmed by the code in open source projects

    Posted: 30 Jul 2019 09:41 PM PDT

    I am working as software developer since last 4 years and I can code in well in C and have intermediate knowledge in python.

    I wanted to participate/contribute in open source projects to learn / improve my coding. After hours of searching for active open source projects which is in C / Python , which is not a huge code base and has decent amount of open issues , I feel overwhelmed by amount of code

    Sorry if it sounds lazy on my part but I do put in a lot of effort and time when it comes to work but unable to find same level of motivation with learning something that is entirely new using open source projects, where I have to read huge code but there are no issues .

    So just looking for suggestions on which projects I can start on, projects which are not big, where I can contribute a decent amount and possibly learn something. I find it hard to read code when I am not looking for an issue . Any other methods to improve coding are also welcome.

    Programming Help in R

    Posted: 30 Jul 2019 05:48 PM PDT

    I have a list of accounts that I'm consolidating, I have a few examples similar to below:

    Menelo corporation, Blue steel industry, rock balboa corporation, black rock industry.

    I want to change all the names that have the word corporation or industry and modify to the below:

    Corporation, Industry, Corporation,Industry. I wrote a function that does just that but it's not saving the value when i recall the data field.

    replace_values <- function(data, column) value.location <- grep(data, pattern = column,ignore.case = T) unique.name <- unique(data[value.location]) before <- paste0('There are ', length(unique.name), ' unique ' , column, ' names ') print(before) for ( value in unique.name) { data[data %in% value] <- column } after <- paste0('Reduce unique ', column,' names to ', length(unique(data[demo.location]))) print(after) } 

    given that i wrote this function

     data[data %in% value] <- column 

    the data values should have changed in my global environment but it remained stagnant. I have also tried str_replace and it didn't wok either.

    The end goal is to pass the function to a for loop and modify a list.

    Is c++ trolling me or am i just stupid?

    Posted: 30 Jul 2019 08:21 AM PDT

    Im currently learning c++ and working on a small project where i need a random number. I need this number somewhere between 0 and 48 so im using rand() % 49 to achieve this.

    The problem: this calculation always returns 13. ALWAYS.

    It works with every other number i tried perfectly fine. Always a random number in that range i define.

    Except if i use % 49..

    int main(){

    srand(time(NULL));

    int a = rand();

    std::cout << a << '\t' << a%48 << '\t' << a%49 << '\t' << a%50 <<std::endl;

    return 0;

    }

    This is what im currently use to test it. It gives me the random number and three outputs for the % calculation.

    Here´s an example:

    757843715 35 13 15

    757877329 1 13 29

    757894136 8 13 36

    757910943 15 13 43

    757927750 22 13 0

    757978171 43 13 21

    Can someone explain why this happens?

    Im completely lost.

    QR based tracking system

    Hi all, i wanna build a tracking system using QR code, i need to build a data base that holds the information about the items i'm tracking, a phone app that reads/writes from and to the database, and an app that prints the codes to he sticked on the items.

    I also need to assign users to the phone app and the database interface each with thier own functionality.

    Where do i need to start, what do i need to learn, and do you recommend any courses? I have a vague idea of what i need but i thought it would be better to ask so i don't get lost.

    I know a little bit of python and HTML.

    Recursion vs Iteration - which is more buggy?

    Do you think recursive is easy to maintain/refactor, or is it buggier than iterative software, or the other way around?

    I'm honestly a bit stumped here. I've been working on something with RPG Maker XP and have found myself using something called Ruby Game Scripting System but I was wondering if there was any differences between it and regular Ruby so I don't end up learning the wrong language again.

    foreign exchange rate monitor/notifier help

    Posted: 30 Jul 2019 07:14 PM PDT

    I'm trying to create a service that can monitor foreign exchange rates and send me a notification either through an email or sms (whichever is easier/cheaper) when a rate I specify is available between 2 currencies using python.

    I've had a tiny bit of experience using APIs and I'm planning to use fixer.io to parse some JSON data to check for my specified rate.

    Since it's supposed to monitor the exchange rates, I'll have to find a way to automate the process so that it checks approximately once an hour, or every two hours (fixer API limits 1000 calls a month for their free plan) and sends out a message if the desired rate is seen. This will mainly be for personal use. I've read a bit about script automation, would that be the case here?

    What I've done so far is use the smtplib python library to try and learn how to send emails using python. I have no idea how to automate this process, or whether that is the appropriate library to use for this type of task. I'm currently sending emails because I think there might be some associated fee with sending an sms, but I have no idea how that works.

    What I need to do is try and figure out a way to automate sending out messages, whether through email/sms using some form of script automation, as well as figure out if smtplib is the appropriate library for this task. I'll then need to figure out how to parse the data from the fixer API as well as get data from a user to specify a rate, a base currency and an exchange currency for a desirable exchange rate, figure out how to compare the current rate to the desired rate, and then send a message back to the user if the comparison is favorable for their specified rate. High frequency monitoring/notification isn't necessary, and I'm trying to keep costs really low since this is just a personal project.

    Any tips on how to tackle this are greatly appreciated
