    Got my first interview in 6 days!!! learn programming


    Got my first interview in 6 days!!!

    Posted: 12 Mar 2020 11:37 AM PDT

    I WILL HAVE MY FIRST INTERVIEW IN 6 DAYS AND I AM SO EXCITED!!! I want to thank everyone, because really, without this subreddit I wouldn't have been this motivated as I am right now. I started from the freaking bottom, remembering when I had my first post here about how to get into the programming field, and now I am in the position of having my first interview. Damn, I can't believe it, it's been a long and nice road until I got here. I applied to multiple companies and got rejected by most of them, but finally, a company called me and told me I will have the interview in 6 days. So anyone who is struggling or is demotivated, just keep going, believe me. You will never regret if you listen to me. I believe in all of you!

    This may be a weird question, but do you guys ever get a rush out of getting something to work?

    Posted: 12 Mar 2020 09:14 PM PDT

    Sorry if this is off topic but I've noticed that I'll have these moments of frustration that feel like they'll never end when I'm getting errors or things aren't working right. But then when everything finally works it's almost euphoric and I get incredibly excited. I finally learned enough to solve my own syntax error and I felt like some sort of god just figuring out something on my own hahaha.

    I just wanted to see if anyone could relate. Does anyone else find the frustration/reward cycle kind of addicting to you?

    recursion

    Posted: 12 Mar 2020 05:46 AM PDT

    I am bad at recursion. I almost always prefer the iterative method. Is there a programming language that forces you to use recursion? I want to get good with it so only way is to force myself.

    How often do you create Custom functions in R

    Posted: 12 Mar 2020 09:32 PM PDT

    Hey everyone,

    I would like to hear from you veterans in R. How often do you create Custom functions while programming? Do you use 80%, 50% of the time?

    I have been learning R for a year now, and I'm interested in functional programming. Trying to understand the logic - for/while loop, if/else loops, and I would like to be proficient in it.

    Any books, course-related to functional programming?

    Thanks

    P.S: Currently learning from Functional Programming in R by Garett.G

    Are there any rules of thumb when writing basic algorithms that can help me figure out what direction I’m supposed to go in?

    Posted: 12 Mar 2020 09:59 PM PDT

    Im doing FCC and I'm on the "writing basic algorithms" section of the JavaScript course. I've finished the JS course here as well as on TeamTreehouse but each section when it asks me "make a function that takes a string as an argument and finds the longest word in that string, and returns the length" and I have no idea where to even start. How do I know when to use a for loop or an if statement or recursive etc. I always get stuck, look at the solution, and think to myself "I would've never thought that." Is there something I'm missing?

    Requesting Help: What math should I know if I want to understand more intermediate topics of programming?

    Posted: 12 Mar 2020 09:11 PM PDT

    I've recently finished my first Programming Language Course on Udemy (50 hr "masterclass" on Python) and I've fallen in love with the problem-solving part of programming.

    I've tried my hand at leetcode and even though I've been able to brute force my way through some 40 questions, it has been a humbling challenge.

    I'm thinking Data Structure and Algorithm classes should come next, but back during math class as a kid in high school I always loved understanding the underlying reasoning/logic behind the math "rules" I employed. Hence, I don't want to go into these classes with a sub-par understanding.

    Eventually, (way further down the road) I'm thinking/Hoping I'll be able to go into Machine Learning, but for now, I'm curious to know:

    TLDR; Which math topics/classes should I have a solid grasp on before diving into algorithms and more advanced programming concepts?

    PS: If you could answer with examples from Khan Academy's math site: https://www.khanacademy.org/math , that would be extra helpful, but any help would be much appreciated.

    Thanks in advance and I hope you're all doing okay, all things considered.

    PHP SCRIPT NOT SUBMITTING DETAILS TO DATABASE

    Posted: 13 Mar 2020 12:28 AM PDT

    The PHP script is not registering users to the database. I've used prepared statements to protect my database against SQL injection. There are no errors in the script and it is still not registering users to the database. I also haven't used PDOs. Can someone please help me?

    Shader question: what does function f'(x) mean?

    Posted: 13 Mar 2020 12:12 AM PDT

    I am asked to make a shader that fulfill the following criteria:

    f(0)=0

    f(1)=1

    f'(0)=dx0 on the right side of 0

    f'(1)=dx1 on the left side of 1

    f(x) is smooth for x in [0,1]

    f(x) = 0 for x < 0

    f(x) = 1 for x > 1

    With close to zero experience in shader programming I am at a loss to where to start. I know that f is the function name, but what about f' ? I have tried googling for it but all I get is how to write a function to calculate a derivative.

    Using other tools in addition to source material

    Posted: 13 Mar 2020 12:10 AM PDT

    Should I only use the source material to learn something or is it ok to use other tools? I'm learning how to use Flowgorithm to help me enhance some example code from a book.

    Alternatives to ModelSim?

    Posted: 12 Mar 2020 11:55 PM PDT

    Hi, I'm looking for a good alternative to the ModelSim software, and was hoping for some suggestions.

    Requirements for capabilities: code simulation, waveform viewing, project management, code editing

    Nice to have: Code synthesizing

    I'm hoping to find an open source software that works on all platforms (Windows, Mac, Linux), though that seems like a long shot.

    I'd appreciate any suggestions or advice, thank you!

    Typescript error TS2322 (Angular)

    Posted: 12 Mar 2020 11:52 PM PDT

    Hi!

    I don't understand why I'm getting this error:

    ERROR in src/app/data.ts(17,12): error TS2322: Type '{ id: number; info: string; }' is not assignable to type 'Hobby'.

    Object literal may only specify known properties, but 'info' does not exist in type 'Hobby'. Did you mean to write 'infor'?

    This is the file it's throwing the error about:

    import { Mydata, Study, Hobby } from "./dataclasses"; const MYDATAS: Mydata[] = [ { id: 1, info: "Kulttuurin ja taiteiden kandidaatti" }, { id: 2, info: "Kotipaikka Jyväskylä" }, { id: 3, info: "Lempiruoat kasvipohjaisia" }, { id: 4, info: "Lempijuomat lukuisia" } ]; const STUDIES: Study[] = [ { id: 1, info: "Cygnaeus-lukio" }, { id: 2, info: "Jyväskylän ammattikorkeakoulu" }, { id: 3, info: "Web-suunnittelijan koulutus (JAMK)" } ]; const HOBBIES: Hobby[] = [ { id: 1, info: "Polkupyörien puunaaminen" }, { id: 2, info: "Graafinen suunnittelu" }, { id: 3, info: "Venyttely" } ]; export { MYDATAS, HOBBIES, STUDIES }; 

    As you can see, they are all pretty much the same (despite the contents) only difference is that I'm getting the error from the HOBBIES class.

    Practice for Java coding test?

    Posted: 12 Mar 2020 11:29 PM PDT

    Hey everyone!

    I got a call back yesterday for my first ever followup interview. I'm excited about it but also nervous as it will be my first coding interview.

    So, I have five days to study for it and I would love suggestions for how to prepare. The role is primarily Java based, and I'll be learning Spring for the role. If it helps, all the technical questions in the initial interview were usual suspects, e.g. what is an abstract class, polymorphism, difference between overloading & overriding.

    I appreciate any suggestions

    Cross platform development with java?

    Posted: 12 Mar 2020 10:31 PM PDT

    As of 2020 there are countless cross platform development tools out there. Since I want to keep my focus on developing in java, are there any that use java as their main programming language?

    I want to develop an application, that's able to run on android devices as well as ios. Web would also be nice but is not a must.

    A Bitwise Problem

    Posted: 12 Mar 2020 04:32 PM PDT

    Hey there! I'm a computer engineering student. And i didn't understand a single word about "bitwise". I've a homework can u help me?

    - Generate random 100 numbers. If numbers 5. bit is = 0, make 4. bit 1 and print numbers into "numbers0.txt" file. If 5. bit is =1, make 3.bit 0 and print them in "numbers1.txt"

    I should use "C". We've learned so less programming and only topics that i know are flows, functions, arrays, structs, and a bit of pointers.

    What are some interesting fields to consider as a fresh graduate?

    Posted: 12 Mar 2020 04:24 PM PDT

    I'm set to graduate in a few months and I'm not sure what I want to do. I currently specialize in web development, having worked as a full stack developer on the side while studying. That's given me valuable experience but it's also left me unsure if that's what I want to do with my career long-term. I feel like there must be more interesting and more satisfying fields to work in, but I'm not quite sure what I want. I'm interested in other people's experience in finding their programming niche.

    RPA - Security

    Posted: 12 Mar 2020 09:35 PM PDT

    Clients are skeptical about usage of RPA tools and basic question being asked is "Is it safe to store passwords and applications (Production apps) on a third party tool ? " .Especially those in the Financial sector there are N - number of compliance checks .To clear the air for many others having same question, all the RPA tools (Blueprism , AA and UiPAth) are compliant in all levels
    1).HIPAA & SOX compliant - Doesn't store any of the customer information.

    2).FIPS compliant - Doesn't store any of the system passwords .They use strong encryption algorithms like AES_CBC_256

    3).PCI-DSS - Doesn't store any of the financial cards information

    4).GDPR - European General Data Protection Regulation compliant .

    Above all these tools are developed to handle "OWASP Top 10 Web Application Security Risks"

    Need help learning to "save" data on Electron

    Posted: 12 Mar 2020 09:35 PM PDT

    Hello again,

    Overview: I'm a programming newb trying to make an app for a friend. It basically will have him input Pokemon names into a "database". It will give him simple stats like winrate and frequency of the pokemon that he encounters. Basically he battles online and I want to make an easy way for him to log what pokemon he encounters online.

    Goal: To allow the user to input data and have it be saved in a file somewhere where it can be loaded and used in the future.

    I am using electron so if you can point me to what methods I should look at for this that would be great!

    Currently making a web app, should I use jquery?

    Posted: 12 Mar 2020 09:24 PM PDT

    I've been lately making a calendar notification web app as a simple project. I used django and postgresql for backend and javascript and bootstrap for frontend. So... the probelm with javascript is that it kind of got clunky and became a cluster fuck of codes. I tried to organize the code as much as possible, but it just makes the code more worse. Like getting a state of the button toggled and changing it is so annoying with javascript. Then I saw jquery is a great library for these tasks. Should I try to swich it now? Then I have to rewrite all my javascript code to jquery? Or do you guys have any other suggestions?
