    Do you enjoy your life as a Software Developer? learn programming


    Do you enjoy your life as a Software Developer?

    Posted: 11 Oct 2019 06:41 PM PDT

    I am currently a senior in high school and I will soon begin a university degree in SoftDev, and I am starting to get nervous about what it will be like to work full time as a developer. I don't think I can stand looking at a screen 8 hours a day for the next forty years of the rest of my life. Is that what I should do? I do not plan to work in any large software company. Honestly, I simply enjoy technology and want decent decent work that is quite comfortable. Actually, I love programming, what I enjoy most is the freedom to solve problems according to my convenience, more or less the same freedom you feel when someone gives you an almost unlimited amount of LEGO blocks: "I CAN DO ANYTHING!". I love solving problems on my own, without having to force myself to follow other rules imposed by the syntax of the language I chose. I love mixing things, exploring different things, like when I learned function pointers in C, oh... I started doing "Object Oriented" programming in C just because I could. Now I plan to introduce myself in Java/Kotlin to develop mobile applications.

    But... I am very afraid of living a miserable life in a few years because all I do is look at a screen. Is software development like this? If so, are there better options for specialization if I finish my career such as Robotics, Artificial Intelligence, Smart Cars? I would appreciate any wisdom, thanks.

    “Learn Python the Hard Way”: a Detailed Book Review

    Posted: 11 Oct 2019 06:49 AM PDT

    Hey guys. As years pass by, "Learn Python the Hard Way" is gradually going out of favor among beginner Python programmers. When it does get recommended, however, people are often quick to bash it without actually explaining its problems.

    In this review, I attempted to outline LPTHW's issues more thoroughly -- but I'm also avoiding extreme statements like "This book is absolutely, objectively bad" because it does have some strong points.

    What is GitHub and why is it useful?

    Posted: 11 Oct 2019 08:27 PM PDT

    This is a topic that I feel like doesn't get covered nearly enough with those learning to become software developers. The concept of GitHub can seem rather abstract and out-of-reach when you're first starting to code, but it's definitely important to know!

    I wrote a whole blog post about it -- here's an excerpt:

    What is GitHub?

    GitHub.com is a website that is used to allow developers to collaborate on projects. It is widely used by companies for version control. In a nutshell, version control means that if something in the code breaks the product, the company can revert back to an earlier version that is still working correctly. Then, they can use GitHub to go through an organized timeline to find out what went wrong, fix it, and get everything back up and running. With GitHub, every code contribution is stamped with the software developer's name, the time it was committed, and what that piece of code was for.

    How can I add a currency exchange rate converter to the android app that I am developing if almost all the available online APIs require an access token and have limited number of access per day/month?

    Posted: 11 Oct 2019 07:52 PM PDT

    I am writing a small android application which has a feature of fetching currencies exchange rates from the internet. I have the code and I know how to do the remote calls. My question however is how to handle the case of the limited number of accesses in some period and requiring an acceas token for the API? I am doimg this project for fun amd I still want to publish it but I cannot leave my access token in the app and for sure I will run out of allowed access to the server when users number increase. I prefer not to pay for those servicessince the app itself won't get me revenue and I don't want to put ads in it. How do developers do this? Thanks in advance.

    I have barely been paying attention in computer organization and my teacher is poor. How do I learn this stuff on my own?

    Posted: 11 Oct 2019 11:18 PM PDT

    This class is basically setup not to learn anything in my opinion.

    Boring slides that don't really go into detail. She doesn't record the sessions, instructor is not inspirational, she doesn't post the slides. Doesn't explain stuff as well as she should.

    She's also kind of annoying about going back on slides. I notice everyone in class just rushing jotting down notes because she moves slides so fast. It's impossible.

    I can't... I mean I can't learn anything from lecture. Lecture has always been a huge waste of time for me. I can't learn from hearing like that. I need to be able to watch a video in front of me and write notes or I need to read a book and then take notes.

    The problem is, we have a book.

    Computer Organization and design by David Patterson

    It's un-usable though because she does not follow the book. It's like... one day of the week were on chapter 2, the other day were on material from chapter 5 then the next day chapter 3. It's not consistent.

    sorry for that tangent, this class is probably important yet extremely frustrating because I feel like I'm being cheated with my money here.

    Does anyone have a course where I can learn this all in like 5-10 hours? I watched some videos on youtube where I learned more in a 10-20 minutes worth of videos then we did the whole 150 minutes of weekly lecture.

    HTML/CSS: will using label{...} target something within a section class? Seems like it doesn't but why?

    Posted: 11 Oct 2019 07:25 PM PDT

    I have the following html snippet:

     <legend>Some Post Data:</legend> <label>Text here: <input type="text" name="text_input" size="30" maxlength = "100"> </label> </br> <label>Number here: <input type="number" name="numerical_input" size="30" maxlength = "11"> </label> </br> <label>Password here: <input type="password" name="password_input" size="30" maxlength="30"> </label> </br> <section class= "radio"> <p>Select between: </br> </br> <label> <input type="radio" name="candy" value="Snickers" />Snickers</label> </br> <label> <input type="radio" name="candy" value="Skittles" />Skittles</label> </br> <label> <input type="radio" name="candy" value="Mentos" />Mentos</label> </br> 

    I have the following CSS:

    label{ margin: auto; padding: 2.5px; display: block; border: 1px solid black; } 

    When I run this, only the labels before <section class = "radio"> is changed.

    The labels within the section class are not bordered.

    Is it because my CSS can't reach within the section class = "radio"? Bit confused.

    Beginner JavaScript project?

    Posted: 11 Oct 2019 05:44 PM PDT

    What is a good beginner JavaScript project I can show to employers? I'm graduating soon and want to add more projects to show once I start applying. I have more experience with java and sql but I want to get exposed to other languages as well. Looking for something I can do in a few weeks/1-2 months. I appreciate any input

    Video resources from the 2000s and earlier

    Posted: 11 Oct 2019 09:50 PM PDT

    Serious question, after watching brilliant videos on freeCodeCamp that are easily better than most lectures and other junk on YT and seeing that they're somewhat recent (some of their best content was released last year); what were decent video / code-a-long resources from the 2000s and / or earlier? I started searching for programming DVDs on Amazon and a lot of the DVDs are quite recent.

    A lot of people prefer visual learning over reading textbooks. I'm sure there had to be decent DVDs teaching / focusing on one language from last decade or earlier. Currently, I can't find old DVDs of such things on Amazon, but I'm sure they existed. Anybody know of any and / or other visual resources to learn to program from last decade and earlier?

    I know this had to be a thing. I've found DVDs teaching calculus I, II, III and so on from around these times.

    Learning two languages at once as a beginner? Java in school and Swift on my own for fun.

    Posted: 11 Oct 2019 11:08 PM PDT

    I've looked around and most people say stick to one language until you get good at it then move on to another. I've been doing that with Java since I need to learn it for school. My computer science major is going to be mainly using Java, but lately I've been wanting to make iOS apps so I want to learn Swift. I've only been studying Java intensely for the past 3 months and understand a lot of the basic programming concepts that can translate to other languages. My biggest worry is mixing up syntax between the two since I'll be learning Java in class and Swift on my own if I do this.

    Should I learn Swift on the side? Or just stick with Java for school? I want to eventually be able to make iOS apps but I don't know if I should wait until I learn more programming concepts through my computer science program at school

    Any advice would be appreciated! Thanks!

    Runtime tests for ArrayBasedList and LinkList?

    Posted: 11 Oct 2019 11:03 PM PDT

    I don't find efficient information about this one's being applied together. It consists in running a series of certain test (let's say 5) and then prints the seconds. Is there any example or reference that I can find online?

    Thanks in advance

    How to handle negative reviews

    Posted: 11 Oct 2019 05:47 AM PDT

    Hi,

    Couple of months ago I've uploaded my first app on Play Store. My plan was never to make money out of it nor to advertise my app so people can download it, it's just for my portfolio. It's really niche app only in one language available, but it got some 50+ downloads and most of the reviews were 5 stars, but also a few negative reviews, for no reason.

    It's really bummer and I can't seem to handle bad reviews, I don't even know what is wrong so I can try to fix it. I've been working on my second app, which is much bigger code base, also for my portfolio before starting to apply for internships or jobs, but I'm getting feeling I'm not suited for app development because of this, but programming's really fun again for me because I was getting tired of web dev.

    Having trouble with comparing strings from 2 different files and getting an Infinite loop <JAVA>

    Posted: 11 Oct 2019 09:41 PM PDT

    Hello! I'm currently working on an assignment for my Fundamentals of Programming class! Here is the question that I'm tasked with completing:

    Determine if a word entered by the user is spelled correctly. A word is considered correct if it's found in dictionary.txt (see required output to get file).

    Problem: So far every time I input a word that's in the dictionary.txt it infinitely loops saying that that the entry is spelt incorrect even though it isn't. Any help is appreciated!

    Here is my code:

    import java.io.*; import java.util.Scanner; public class LOOPS2Q5 { public static void main (String[] args) throws IOException { Scanner keyboard = new Scanner(System.in); String wordToCheck; do{ System.out.println("Enter word to spellcheck (or exit to end)"); wordToCheck = keyboard.nextLine(); if (wordToCheck.equalsIgnoreCase("exit")) { System.out.println("Ending program..."); System.exit(0); }else{ File file = new File ("dictionary.txt"); Scanner inputFile = new Scanner(file); String line = inputFile.nextLine(); while (inputFile.hasNext()){ if (line.equals(wordToCheck)){ System.out.println(wordToCheck+" is spelled correctly."); }else{ System.out.println(wordToCheck+" is not spelled correctly."); } }inputFile.close(); } } while (!wordToCheck.equalsIgnoreCase("exit")); } }

    Need help figuring out this assignment.

    Posted: 11 Oct 2019 08:58 PM PDT

    This is the assignment outline.

    https://privatebin.net/?e9364c19893b04d5#AZTc6936kNCb8wdbgZf799ujBVnRudf7j4iudQUTWvoa

    This is what i have so far:

    https://privatebin.net/?05bd6acda36625ee#7oCSNoM4BGemiCs56MomJ9qUhtLWtZSFBD6kKDELDpZ4

    So far ( to my nooby knowledge), ive successfully gotten to the "what would you like to drink section" but am confused on how to store the user input and print it out (with the correct math for upgraded items) at the end. Is any of my code correct? Am i doing this whole thing wrong? If its right, where do i go from here?

    Note from my prof:" Looks like you have a bunch of nested functions inside of your main function. Instead your main should look something like this:

    def main():

    SelectedCombo = getCombo()

    Size = getSizeFromUser()
    SelectedCombo.setsize(Size)

    #same deal for drink

    SelectedCombo.displayCompleteOrder()

    return 0 "

    this also confuses me, not quite sure what to do with it.

    Best educational option for successful web development career?

    Posted: 11 Oct 2019 08:51 PM PDT

    Hi everyone, I'm thinking of pursuing a web development career. But, there are a few avenues I have available near me to tackle this career option. (I already have a bachelor's in psych and want a career change.) I'm based in NC if that helps...Thanks!

    Which of these options would be the best for employability?

    1. A certificate program at a local community college for web development (1 semester) ;
    2. An online web development post-Bachelor's certificate from a state university (2 semesters) ;

    3, Comp sci as a second Bachelor's (2 years +) or

    1. Associate's in an IT subject (2 years)

    Best way to learn how to type?

    Posted: 11 Oct 2019 08:47 PM PDT

    Hello. I'm a very unique programmer: I can't type without looking at the keyboard. When my eyes are focused on my screen, I just cant type. I forget where all the keys are. But when I look at the keyboard, even if I just stare at one key and don't look at any others, I can crank out line after line like a machine. It's the strangest thing.

    I'm a third year in college, so I'm starting to look for a co-op, and I feel like most employers want their employees to be looking at their screen and know how to type, even if they are just as effective when looking at the keyboard. And even if employers dont mind as long as I'm just as effective as someone who can type, I would still like to be able to see my screen as I'm typing. I feel like it would help me code even MORE.

    My question is: what do you think would be the best way for me to learn how to type? I've tried like simple online ones for kids, but it just doesnt work for me and I end up reverting back to looking at my keyboard.

    Thank You!!

    How to Create a Program that Confirms whether or Not the Inputted Word is in Another Text File?

    Posted: 11 Oct 2019 08:04 PM PDT

    The other file's name is "dictionary.txt", and it is in the same src file as this program, but yet my program can't seem to locate it.

    Here's my code:

    import java.io.IOException;

    import java.util.Scanner;

    import java.io.FileReader;

    import java.io.BufferedReader;

    import java.io.File;

    public class Dictionary

    {

    public static void main (String[] args) throws IOException {

    File a=new File("dictionary.txt");

    String[] words=null;

    FileReader reader=new FileReader(a);

    BufferedReader c= new BufferedReader(reader);

    String d;

    Scanner keyboard=new Scanner (System.in);

    System.out.println("Enter word to spellcheck (or exit to end)");

    String input=keyboard.nextLine();

    int count=0;

    if (input.equals("exit")){

    System.out.println("Ending program..."); 

    }else{

    while((d=c.readLine())!=null){ words=d.split(" "); for (String word:words){ if (word.equals(input)){ count++; } } }if (count!=0){ System.out.println(input+" is spelled correctly."); }else{ System.out.println(input+" is not spelled correctly."); } }reader.close(); 

    }

    }

    And, here's my errors:

    Exception in thread "main" java.io.FileNotFoundException: dictionary.txt (The system cannot find the file specified)

    at java.base/java.io.FileInputStream.open0(Native Method)

    How do I get into data visualization and/or data modelling?

    Posted: 11 Oct 2019 06:55 PM PDT

    I have a running knowledge of HTML, JS, and React Native. Web and mobile development languages which. while fun, really imo don't have much place in the workplace if you're not at a coding firm. As someone who would like to meld my love of politics and coding, what languages or tools could I possibly pick up to create models similar to the CSIS Guanxi Map (which I swear exists.. It's an interactive clickable map showing relationships of different CCP members) or the various Belt and Road Initiative maps that outline how much money is being spent in which countries on which projects. How are these things generally produced, and is there a proper name outside of "data visualization" for these kinds of projects?
