| Posted: 17 Jan 2021 09:43 AM PST I feel like I've been very reliant on the tutorials and now I want to actually start learning and practicing doing things on my own. I'm leaning towards progressing through codewars but even the easy problems are too much for me. Where should I start at this point? I kinda feel like I've been a phony this last few months. Edit: I'm going to try to reply to everyone but in case I miss you. Thanks everyone for the words of encouragement and advice. I think I need to just view these DS&A skills and web dev skills as parallel tracks that I need to practice separately. I feel pretty okay about actually using JavaScript but I'm realizing I was just never taught these DS&A concepts. I'm going to start splitting my time into learning them specifically, thanks everyone! [link] [comments]  |
| Posted: 17 Jan 2021 11:31 PM PST I'm a 2nd year College studying Computer Science, like I said I am stuck at the fundamentals, I can't even fully understand the For loops even though I watched many tutorials videos on it and explanation of it. What do you think I should do to advance my learning. I love programming and I don't wanna stop here HELP [link] [comments]  |
| trying to add/subtract values in an array, returning NaN Posted: 17 Jan 2021 10:37 PM PST beginner javascripter, working on some challenges i found online, and im running into a wall on this one. code looks sound but im returning NaN on each test run. heres the code var number = function(busStops){ var tally=0; var i, j; for(i=0; i<busStops.length; i++){ return tally; } my instructions: You are provided with a list (or array) of integer arrays. Each integer array has two items which represent number of people get into bus (The first item) and number of people get off the bus (The second item) in a bus stop. Your task is to return number of people who are still in the bus after the last bus station (after the last array). [ [10,0][3,5][5,8] ] are being injected into busStops with the expected return value of 5 (+10 - 0 + 3 -5 + 5 -8) my code looks pretty solid to me to run, but tally returns NaN. any ideas? TIA. edit: figured it out thanks to the replies. i had to modify the tally line to reflect tally+== busstops[i][0] - busstops[i][j] and it worked. [link] [comments]  |
| Posted: 17 Jan 2021 05:04 PM PST Currently work as a 3d artist in a construction and design company. I've been wanting to be a game developer, but I have zero knowledge in programming. I'm confused which programming language I should learn first? And if it's even worth it. How many years will it take? Will I get a job within a year if I spent 6hrs every day learning? Kind of worried because I'm already 29. [link] [comments]  |
| Best way to store hundreds of custom entries locally Posted: 18 Jan 2021 01:00 AM PST I'm making an app to store and visualize data about boardgame plays. The problem I quickly ran into is how to store each individual play. Depending on the game the fields that each play should store may vary, for example, some require to store game score, while others only boolean state "win/lose" and some of them need both. In my previous projects, I used JSON to store data but considering that now I need to store hundreds of entries it doesn't seem very efficient. What would be a better way to store a lot of entries that may contain different data but generally follow some template (defined by each boardgame in this case)? Currently, I plan on storing all of the data locally and I use C# if that matters but am willing to look into something else. [link] [comments]  |
| Which IDE are programs made by Apple developed in? Posted: 17 Jan 2021 08:57 AM PST I don't mean made for Apple, but by Apple:iOS, iTunes etc. Do they use XCode? Because I heard from a Microsoft developer online that all of the Microsoft programs, including Windows itself, are developed in Visual Studio. Does the Apple use their own IDE for that as well?

| Need ideas on final year projects Posted: 17 Jan 2021 11:16 PM PST My initial idea was to make a Pi temperature sensor along with an interface(or app) but the supervisor said it was too simple, he wanted me to focus more on the programming part. [link] [comments]  |
| First developer interview tomorrow. Any advice? Posted: 17 Jan 2021 08:32 AM PST I have my first interview tomorrow. I have been self learning for about a year now and have an interview with a company for the role of Java Developer. I will be interviewing with the team lead who knows I'm self taught. It will be my first development interview and I am terrified. Most of my learning has been in web dev so I feel extra nervous as I have only taken one course on Java specifically. It is only a 30 minute interview, what questions should I expect? Will there be technical questions for such a short interview? Any last minute prep that would be a good idea? Any advice at all will be appreciated. [link] [comments]  |

| Anyone struggling to pay for courses due to stinginess? Posted: 17 Jan 2021 07:21 AM PST I always use inferior free courses offered by my company or those publicly free even when I see great reviews for paid courses. My friend ended up sharing one of his paid courses that had high reviews and it was so much better than what I was using. I was able to learn much faster and practice more. This saved time could be used to earn money from side gigs that could more than pay off the amount spent on a course. This would indicate spending money on a high quality course has a good roi and is a rational decision. The problem is that I have a hard time actually getting myself to pay for courses since I hate paying for anything other than living essentials. I wonder if anyone else has this problem and how they overcome it? Edit: I'm a full time software engineer with a Bachelors in computer science with a reverse spending problem. [link] [comments]  |

| How do I get my code to run in visual studios 2019? Posted: 17 Jan 2021 11:01 PM PST Hey all, I just recently signed up for a C++ course as a tech elective through my college. I was planning on running with microsoft visual studios 2019 for assignments and whatnot, but I cant get my code to run. Im just trying to do a basic hello world program following the program my instructor laid out and while I can build it with no errors nothing comes up where I can see that it is in fact printing hello world. Any help understanding what is going on and how to actually run it would be much appreciated. [link] [comments]  |

| Struggling with leetcode? That's normal. It's NOT for beginners - do this! Posted: 17 Jan 2021 01:56 PM PST I see beginners that get stuck with Leetcode and get disheartened but they don't realise that Leetcode is for Developers who are more so intermediate/advanced. I have done several junior developer technical interviews and not seen one question that is harder than the easiest question on Leetcode. 6 months ago I couldn't do a single leetcode until I found code wars. Codewars is way way better for beginners and helps you build the skills required to solve those leetcode problems: Step 1: sort Codewars challenges by MOST COMPLETED Step 2: Do them! Step 3: Can't do them? Check the solution and try to do it again, maybe another way. Step 4: Remember the type of solution you had to come up with because you will probably need it again. These algorithm challenges are all about patterns, tricks and things with the languages you learn from practice. Here is the link to the challenges: https://www.codewars.com/kata/search/my-languages?q=&&beta=false&order_by=total_completed%20desc It starts with simply adding to numbers or multiplying numbers, reversing strings and then more difficult from there. A much more reasonable starting point than leetcode. Source: I started learning in March 2020 and with no idea of programming and now I start a job as a Junior Developer. It's not because I'm talented, its because I kept practicing these things. Looking at solutions, understanding solutions and trying to solve problems on my own. [link] [comments]  |
| Posted: 17 Jan 2021 09:26 PM PST Hello everyone. I have been assigned a task to build turtle graphics on my own. Using array floor[50][50]. Then printing a sketch pad. Initially all the array elements should be 0 and those should be assigned 1 which the user asks. That is he uses pen down pen up turn right left, and the numbers of spaces he tells us. The program should print any symbol of our choice from the arrays that have been initialized to 1 through the user's instructions. I only want someone to explain me the problem and the approach I should take. I DON'T WANT ANY SOURCE CODE. SO FAR I HAVE PRINTED THE FLOOR[50][50] SKETCH PAD AND I AM HAVING PROBLEMS IN GENERALIZING THE COMMANDS. [link] [comments]  |
