| Awesome cheat sheet for must know data structures and algorithms Posted: 30 Jan 2018 04:31 PM PST I was searching for materials to review for an upcoming interview and I found the Big-O Cheat Sheet. It's got Big-O information and quick links to all of your basic data structures and algorithms. This is a great resource to check when you're starting a new project or preparing for an interview.

| Posted: 30 Jan 2018 01:08 PM PST Edit: "if you have no idea what you want to do in life" I'm basically at a stage in life where I'm sad and frustrated about the fact that I have no prospects, no real skills, and hard to come by motivation. In all honesty I'm probably depressed, but I made the resolution this year that I would start doing something. Anything that might lead to a career. I always think about programming as a possible direction, and I've been trying (barely) to learn since I was 13. Made very little progress, but I know the basics of HTML/CSS/JS pretty well, done a bit of Python, a bit of Ruby, a bit of Swift/iOS, but nothing beyond basics really. Do you suppose it's possible for me to get a real sense of what a career in say, JavaScript development, will be like in 1 year, if I truly apply myself to learning? [link] [comments]  |
| Learn React by Building a Countdown Timer Posted: 30 Jan 2018 01:53 AM PST Hi! I am a 16 y.o that aspires to be a full-stack web developer. I have been learning Back-end and React/Redux for the past two months of holidays and decided to start my programming blog on web dev. My first post is a tutorial on React. All you need is basic HTML and DOM manipulation with React. Feedback is appreciated! [link] [comments]  |
| Posted: 30 Jan 2018 02:06 PM PST tl;dr: truly just a celebration post. Now back to work! If you think you may truly be passionate about programming sometime, never stop trying to learn. I have been having a lot of mental hurdles lately, getting down on myself. Not being able to truly understand how Bootstrap works was really frustrating for me and I thought I would never be able to get passed it. Then I found a resource on here called freecodecamp.org and I thought I would give it a shot. Started from scratch. Everything from colors to heading tags. Was very trivial in the beginning but I wasnt going to stop. I had a feeling. Got to the part on Bootstrap and everything started to click! I've got a whole new level of motivation now and I just thought I'd share. Remember, nobody is perfect at something the first time they try it. Everything takes time. Keep hustling fellow programmers! [link] [comments]  |
| After learning all the basics, how should i move on in my coding journey ? Posted: 30 Jan 2018 11:48 PM PST Hey everyone, I have inished learning python and after trying out my first problem on codechef i was not able to do it until i saw the answer. can anyone guide me through the steps i have to follow to become an expert in programming ? Thanks in advance. [link] [comments]  |
| Keep Java code running? (I need a server?) Posted: 30 Jan 2018 10:26 PM PST So I made a Twitter bot for a project I'm working on and it runs fine, but the problem is that I have no Idea how to keep the code running 24/7. I originally tried running it on a raspberry pi 24/7 but it gets pretty hot quick. I ported the code over to an Android app to keep the bot alive via service, but their's risk of connection drop, my phone dying, etc... So, (even though I have virtually no experience with servers) is there any way I can keep the code running via a server? Will I have to make my own? If so, what languages would I need to learn? Any help or links to helpful articles is greatly appreciated. [link] [comments]  |
| Any other moms learning to code? Posted: 30 Jan 2018 08:16 AM PST I'm hoping to find some other moms teaching themselves how to code! I have a 6 month old daughter and I've been teaching myself Python every night for the past few weeks. Would love to here how your learning is going also ! [link] [comments]  |
| Orange county/huntington beach/Irvine coders? Posted: 30 Jan 2018 11:06 PM PST I am a total newbie. I just turned 27 and want to begin programming. I have a good c++ book and I am doing harvard cs50 course. I live near orange county and I am wondering if there is anyone out there that would be a "mentor" so to speak? I am looking for meetups but I think that's too far past my reach right now. [link] [comments]  |
| What should I study to move away from being a beginner? Posted: 30 Jan 2018 02:30 PM PST I've been "studying" (i.e. fiddling with) programming since I was 14 and, being a logical thinker, I picked up most of the things about programming pretty quickly. However, because of never formally studying programming, many concepts, even some base ones, are completely foreign to me. Now I'm in university, studying something unrelated, but I love programming (solving problems, really), and I wanted to get deeper in it, actually understanding it, and graduating from being a "beginner" (hurts being one for 6 years, duh). I've read about lambdaschool recently, and I think their syllabus is something like what I'm looking for, though there's really no way for me to take that course due to time restraints. The idea would be having something that teaches you concepts, tests you on them and then lets you go forward, but focuses on the essentials. Where do you recommend I start? Is there any (free) good resource? [link] [comments]  |
| Posted: 30 Jan 2018 12:42 PM PST Planning on writing an application in c++. I work on Linux, specifically Ubuntu (pop os) so I use GNOME. The application has to be cross platform while still retaining the same theme across every desktop environment and platform. It should look like an application from 2018 as well, not like it's straight out of windows xp (don't mind it being bulky, but should not have its own classes for everything like QT). Any suggestions? [link] [comments]  |
| Interested in Data Structures / Algorithms? Don't know where to start? Posted: 30 Jan 2018 01:48 AM PST I'm writing a series of articles on the most essential Data Structures and Algorithms topics. The series is aimed at being able to teach the core of these topics to even those with just a few weeks of programming under their belt. If this is up your alley you can check it out the first post here. I'm very interested in hearing feedback, especially from beginning programmers. If anything was confusing or if you have any remaining questions, please leave it in a comment below and I'll try to respond and make the article better. [link] [comments]  |

| Wanting to get back into game dev Posted: 30 Jan 2018 03:30 PM PST Hello all, So there was a period of time where I was really into it but I realised I wasn't really learning and none of the code was getting stuck in my head. I have and want to learn C# for Unity game development. I made some simple games following YouTube guides, but the things I was doing wasn't sticking in my head. So I just slowly got burnt out of it. Game Dev is something I really am interested in and want to do but I don't feel any sort of progression or learning whilst I'm doing all these things. Has anyone got any advice, tips, things to follow etc for me? Thank you very much in advance :) [link] [comments]  |
| Posted: 30 Jan 2018 05:38 PM PST I have read this several times, and yet I am unable to grasp the beauty of the concept of OOP. I work with a software that is written in Java, and I use its API, and frequently write code in it. Code that will allow me to find relationship between things, to run queries, to store or delete things, to fetch attributes. In some sense maybe I am using OOP, but I don't know the difference between Private and Public. Never needed to. I don't write multiple classes, in several packages. I use design patters, but never really grasped that either, because I never had to create one. When someone talks about polymorphism, I understand what the book is saying, I don't understand how it helps in real world program. I studied C in school, and I could grasp all its concepts. I understood flow, control, pointers, data structures, everything. When I studied Java, I did not get it. How is a class an improvement over struct? [link] [comments]  |

| Replacing characters on standard out. C Posted: 31 Jan 2018 12:11 AM PST So I am writing a program in C that takes in a few command-line arguments and also reads a file and prints it to standard out. This is my code thus far (I have indicated at the very bottom of the code in a comment where my problem is): What I'm trying to do now is modify the script that is printed on standard out. Specifically, wherever there is a "#A#" or "#B#" character in the file, I want to replace it with the float values of a and b respectively that I have implemented at the beginning of the program. These float values should be up to 6 decimal places long but I don't really believe that is my problem. I am more concerned about how exactly I would replace the above characters with the float values. Are there any functions in C that can do this? I have googled for functions that can replace characters but to no avail thus far. Any help would be highly appreciated! [link] [comments]  |
| Help with making a text based game with UI Posted: 31 Jan 2018 12:08 AM PST Hi, I've been wanting to make a text based game for quite a while. I'm decent at java, and managed to make a nice roguelike game in terminal with Trystan's RL tutorial. Anyway I've played about with libgdx for a bit, but it seems very complicated for what I want to do, particularly with the handling of large amounts of text. Here is a quick mock up I did of what I'd like the UI to be like. Can anyone point me towards some resources to get started? Most of the libgdx tutorials are for more actiony games, so would I be better off using something else? Ideally java based as that's what I'm familiar with. Any help is appreciated.

| When should I start using unit tests for my program? Posted: 30 Jan 2018 11:48 PM PST Hi, I just learned about unit tests and some benefits that they have. Up till now, I have been writing some small apps but never wrote tests for them. I simply coded the program and checked for bugs myself and if there were any I tried to fix them. I can imagine that for bigger programs, tests might be useful, but how do you know when you should be writing tests? I have always been fine with not writing them.. Any advice? [link] [comments]  |
| My coding project: Munging my Chrome Bookmarks - need JSON schema for the Chrome Bookmarks file Posted: 30 Jan 2018 04:14 PM PST I am looking to re-gain my chops with a little programming project, and I'm looking for the schema for the Chrome bookmarks JSON file. I'm starting my return to programming journey by scratching an itch - munging a collection of bookmarks curated over 15+ years (over 3000). (NOTE: This is not about whether these bookmarks are still relevant - it's about using this as a frame for a programming exercise) I have a couple of Chrome profiles (let's call them Profile 1 and Profile 2) where I synced a large set of bookmarks from Profile 1 to Profile 2 at some point. I stupidly made updates to each Profile's bookmarks after the sync, so they each have the same starting base, but also now have unique new bookmarks and folders. The programming exercise I put to myself is: Read in both sets of bookmarks from the local Chrome Bookmarks file, and 1) Check each link to see if it's dead. If so, move it to the Dead Folder 2) Of the remaining live bookmarks, merge them into a single Bookmarks file. What I'm missing is a definitive schema for how Chrome formats the Bookmarks JSON file, so I can use that to write the code that interprets, stores and re-writes the file. Anyone found this info? Anyone tried this exercise before? Thanks, [link] [comments]  |
| Posted: 30 Jan 2018 07:10 PM PST Does anyone here have a strong preference for documentation (as in the stuff provided by the foundation or company that develops a language) vs. multimedia tutorials for learning programming languages? I'm relatively new to actual programming but pretty experienced at HTML and CSS, and I noticed that my big breakthrough with Bootstrap came when I abandoned video tutorials altogether and just started reading the documentation on getbootstrap.com I'm wondering if the same thing will serve me for learning PHP and JS? I just finished going through a really long video course on PHP on udemy and I can't help feeling I'd be further along now if I'd just read the php.net docs and built things, instead of painstakingly typing out so many lines of code to learn how to make a site that includes form validation. That said, I'm open minded. There are some video tutorials I have enjoyed, I remember watching one on Ruby on Youtube that was good, I think what I liked about it was that he didn't hold your hand through a project just explained how to do individual things in the language.

| Why is the brute force method of calculating x^y O(2^n)? Posted: 30 Jan 2018 06:58 PM PST So multiplication is O(n2) right? So if you multiply x y times, how come the time isn't O(y*n2)? By brute force method I mean calculating let's say 55 by doing 5 x 5 x 5 x 5 x 5. Also, the 'n' in '2n' refers to the number of bits. Thanks! [link] [comments]  |
| Need recommendation for paid online courses with mentoring. Posted: 30 Jan 2018 09:14 AM PST I'm a Graphic Designer, but I mess with HTML and CSS since I was 15 years old (I'm 27 now). I'm fairly confident with those 2 languages, and I can design and code a static website in a reasonable time. I use templating engines sometimes and Sass is crucial. 8 months ago I managed to get a job in a tech company as a Junior Front-End Developer. My main activity consists of maintaining several websites that belong to the company... make a hot website now an then, design and code a new page/section for existing website and etc. I don't have much contact with JavaScript/jQuery since I don't know much about it and most of what I do, doesn't require it. About 2-3 months ago I've started taking some free courses that focuses on JavaScript but I feel stuck and I can't see much progress... I try to compose well formulated questions and I ask around on Stackoverflow/other communities but most responses aren't helpful. I need a professor/mentor. Someone that I can consult on even with the stupidest of questions. I understand the syntax and the basics, but my problem solving skills/logic is not that great. Recently I've been asked (more like imposed) to manage a ecommerce, and the platform that they use depends heavily on their APIs and a lot of JavaScript hackery... the platform feels very archaic, but they are about to release a brand new version using React. Anyways, they know that I'm not good with JS and are willing to invest in my education. So, I come to you guys to ask for advice on good paid online courses that have mentoring. What paid online courses have you guys taken? What was your experience like? My main focus is to learn JavaScript, React, APIs and maybe Python/Ruby? Any input would be greatly appreciated.

| Which back end language should I learn first PHP or NodeJs ? Posted: 30 Jan 2018 06:11 PM PST I want to make a website for my assignment project. I've already learnt HTML, CSS, JS and jQuery. Now I want to move to the back end part, but I'm not sure what to choose PHP or NodeJS. I'll learn both eventually but no sure which should I learn first. P/S: I have 3 months deadline for this assignment. [link] [comments]  |
