| Posted: 09 Jun 2019 05:32 PM PDT Hello everyone, Kyle here. My friend and I have been working on Hypevertise | Free Instagram Auditor, our first big side project, for the past couple of months and we just launched it last week. The craziest part is that we didn't even know how to write code 1 year ago. While we're definitely not experts, I think there are a few pieces of advice I can pass down to everyone on their learning journey, hopefully you can find some motivation out of this post as well. Quick Background My friend and I are fortunate enough to go to school to learn programming, but there was still a lot of self-learning required to complete this project, about 90% of the technologies used in our project weren't even mentioned in school. I think anyone learning to program, whether in school or alone, will find the following advice useful. So, here are the main pieces of advice I'd like to give someone hoping to launch their own side project some day: Persistance Persistence. It sounds corny but there's a reason I put it first, without persistence you'll never finish any task you set out to do. In the world of programming, persistence is key, you need to be absolutely relentless on breaking through any barrier that gets in your way when it comes to writing code. When you run into a problem, be sure to exhaust all of your resources, I'm certain someone will be able to help you. Here are some good places to look for help when you feel stuck:
There are far too many barriers when programming, so if you're not persistent you will never see a task through to the end. Break big problems into smaller sub problems, research the sub problems and piece together the puzzle, by using this approach you will not only be able to solve your problem, but you'll also leave with an in depth understanding of the problem so when it happens again you know what to do. Limiting Mindset Stop putting a mental ceiling on yourself, a lot of people stop before they even start. When you have an idea for a side project, instead of convincing yourself that the idea is above your skillset, approach the problem systematically and just worry about one feature at a time. By focusing on one small feature at a time you will be able to actually begin your project and slowly build on top of your code feature-by-feature. Just because your teacher at school didn't teach a specific concept or technology does not mean you cannot use it. When working with a new technology a good approach would be to google, copy code, study the code, modify the code and move on to the next feature, eventually all the moving parts will make sense. Limiting yourself to what was taught in the curriculum will only leave you being just as good as the next guy. Organization/Planning a Project This seems like a big deal, but it's really not. Don't spend months planning your project, how it's going to make you money, etc… Just figure out what you want as a minimum viable product (MVP) and roadmap the rest of the features for future implementation. This will allow you to start building right away, because no matter how much planning you end up doing, you're still going to run into roadblocks. Spend some time on figuring out which technologies you will need in order to get started and just start building, chances are you will start replacing code and optimizing your early work as you continue with the project. Also, don't worry about using the newest bleeding edge technologies, just build with what you can and learn as you go. Networking A lot of people think that networking is something you only need to do when looking for a job, but the truth is you should be doing this every day. By networking with people in the industry you're going to find people that are more experienced, this will allow you to build a circle of people that you can reach out to whenever you need technical advice or help. Networking doesn't have to be in person, meet people online, at local meetups, etc… This will be an invaluable resource as a lot of these people have probably encountered technical challenges that you will encounter along the way as well. Now you have a circle of people you can reach out to when you're stuck. Conclusion I wanted to keep this post non-technical for the most part as there is already tons of solid technical advice on this subreddit already. Programming is a very mental game, and I think applying the advice above should get you in a good position to accelerate your learning process. Like I said above, I'm not claiming to be an expert and I'm sure there is a lot more that can be added to this but these are just a couple things that myself and my friend have learned throughout the process of building our first real-world project. If you made it this far, thanks for reading, and feel free to add your advice/suggestions below! [link] [comments]  | ||||||||||||||||||||||||
| The need for a physical "duck" when Rubber Duck Debugging Posted: 09 Jun 2019 12:10 PM PDT I'm curious, out of the people here who practice Rubber Duck Debugging, how many people actually use a physical object/duck for the process? I practice the technique, but I have it as a "conversation with myself" in my head instead. I've never been inclined to include an inanimate object in the process. What do other people do? Has anyone found any benefits to actually using a physical duck/stand-in? Or is this just a matter of how you focus? [link] [comments]  | ||||||||||||||||||||||||
| Posted: 09 Jun 2019 04:51 AM PDT I'm looking for good resources to learn C# if your a noob at programming and the C# language. I've read through the general FAQ on this subreddit, but unfortunatly there aren't any suggestions like for C++ as an example. If I search Google there are plenty of results. Free stuff from Microsoft (which is kinda short) and paid courses like Udemy. It's hard to judge which is a good place to start. I would prefer a resource that uses Visual Studio as IDE because I have some experience with that IDE. [link] [comments]  | ||||||||||||||||||||||||
| How do I raise a number to a power that is between 0 and 1 in c++? Posted: 09 Jun 2019 04:36 AM PDT So for example, if I want 30.76, or 0.240.33, or 4.320.041 Is this possible to do in C++? [link] [comments]  | ||||||||||||||||||||||||
| Posted: 09 Jun 2019 07:14 AM PDT So I finally started learning web development via this tutorial on geeksforgeeks. I was using Firefox to test everything, but just randomly checked the file on other browsers and it's totally different. Check the screenshots below: https://postimg.cc/gallery/hsdmdd1k/ This is the source code if anyone is interested: https://gist.github.com/parvinderandroid/a751bce521c3a4aed6ff26f2272838f5 [link] [comments]  | ||||||||||||||||||||||||
| Interview question: How do you know when testing is sufficient? Posted: 09 Jun 2019 08:03 AM PDT TL;DR: Experts or interviewers of software development teams, what's an acceptable answer to the above question? On an interview a while ago and I was asked this question. Rest of the interview went pretty well (still got the job so hoorah), but I've always felt like an idiot in my attempt to answer this one. I was still an undergrad CS major during the time, and this is my first real software job so I have basically zero background in formally testing my code. I started going on about what I knew about unit testing, importance of identifying edge cases, automated scripts to test large sets of inputs, yada yada. After I finished my spiel, the interviewer simply hits me with "So how do you know when it's sufficient?" At this point I realized I didn't actually answer the question at all. After a few moments of silence, I attempted again by saying it depends largely on the nature of the project. I'd feel more comfortable with a prototyped release of non-critical software with relative minimal amounts of testing compared to a system that needs absolute assurance of reliability if it's a production ready release of life-critical software (which this company does work on). Shot myself in the foot on that term "absolute assurance", because then the interviewer asked the obvious question
At this point, I'm feeling like I dug myself into a hole. After a longer silence, I tried to save some face by saying there are languages such as Frama C that provide frameworks to essentially "prove" your program correct. I'm personally not too familiar with that however, and I'm sure it has flaws itself. And beyond that, as a software developer, you can never be totally certain your program works the exact way you'd expect. Finally the interviewer relented on that question, and we got to move on to the rest of the interview. I know interviewers often just like to see your thought process and what you consider, but even with more research I've still yet to think of a good answer to this question and it's been driving me up a wall. What's the community's thought on this question? Interviewers, what are you looking for in the answer? [link] [comments]  | ||||||||||||||||||||||||
| Fastest way to know if you love or hate coding? Posted: 09 Jun 2019 06:52 PM PDT I have started learning to code several times and never managed to reach intermediate nor advanced levels. Java when I was a teenager. C in college as a mandatory module. Crash course in C++ a few years after grad. Lesson 3 of CS50 Each time I manage to complete and pass the tests but always going through full time school/work in another field. It never appeared that I would have a use for it, unlike say Japanese which is great for holidays and anime. I'm now thinking of switching careers into tech or data science, but before I invest too much I'd like to spend a few months intensively studying so I don't make a mistake.

| Is there a resource for finding programming jobs / languages per city? Posted: 09 Jun 2019 09:09 PM PDT I live in Columbus, Ohio and I'm trying to figure out what needs companies in the city have so I can focus my efforts on a language that might net me a job here. Is there a good place to look up programming jobs per city? [link] [comments]  | ||||||||||||||||||||||||
| Posted: 09 Jun 2019 06:32 PM PDT So according to my university program I already know OOP, Data Structures, Data mining and other things, but the teachers and assignments are really really bad, and it's not just me to think that, also many of my classmates, so now that I'm trying to get into data science with python I find myself knowing nothing about data structures beyond going through an array with a for and nothing much more complicated Is there any suggestion you have so that I would feel more comfortable with those topics? I had thought about a 2D game for data structures and then some kind of web project to later move to something more science data related. Thanks! [link] [comments]  | ||||||||||||||||||||||||

| What are various architectures available for web application? Posted: 09 Jun 2019 11:04 PM PDT I already know about client server and p2p model. Are there any other architectures/models available to use? I am looking to build the service in python [link] [comments]  | ||||||||||||||||||||||||
| In Python, how do I re-order a cross tab? Posted: 09 Jun 2019 05:01 PM PDT It looks like it prints it out in alphabetical order. So I've got simply: pd.crosstab(data_2019.HOUR, data_2019.DAY_OF_WEEK) and it gives me:
I would like to make the days be in order i.e. Monday, Tuesday, ... , Sunday [link] [comments]  | ||||||||||||||||||||||||
| Reverse engineering an old MMO bot Posted: 09 Jun 2019 10:54 PM PDT This is just for fun. I am not very well versed in programming. I started as a CS major and ended up majoring in something else so I have taken some classes but never anything advanced. I have played this old MMO that came out in 1998 for about 18 years now. It has a very small community now and is really not getting updates or anything. Despite, or perhaps because of that, the community has created bots for it. Basically all of the iterations of the current bot came from one player's code a long time ago. I spoke with him before he stopped playing and basically all I know about it is that it was written in C#. (I say he "stopped" playing but I imagine it is pretty hard for him to play in an orange jump suit!) I'll explain how the bot works as best as I understand it: The bot creates a client window and by doing that it can monitor the packets (I guess?) that are coming in from the server. Things like creature spells/attacks used, creature profiles, map positions, character/monster status (debuffs, buffs, hp/mp, etc.), and other stuff like that. It then interprets them and responds in kind by removing debuffs from your character, healing, casting offensive spells, etc. My point is, it is not just an autoit script that hits a creature, picks up gold, moves to next creature, rinse and repeat. Instead, it is pretty "advanced" for a bot created for such an old game. I would like to reverse engineer it because I think it would be fun and the creator left without leaving any source code. Particularly because when a new spell, skill, item, etc comes out (once in a blue moon), there is no way for the program to know what they are and therefor cannot use them. I imagine that this means that these things are hard coded and must be added to the program and recompiled as a new version for them to work. I know that it is damn near impossible to extract source code from a .exe but I just want to tinker anyway. I opened it up into dotPeek foolishly thinking that I could just get the source code that way. Needless to say, I couldn't, but I can see a whole lot of code that makes a lot of sense to me leading me to believe that I am just missing a little bit of code or perhaps a little bit of knowledge (ok maybe a lot). I also heard about ghidra recently but that seems too advanced for me. I am kind of just poking around in the dark hoping to find something interesting. Ok so my questions. For what it is, this bot is pretty advanced stuff, at least for the likes of me, so I really want to learn from it. Am I going about this the right way? How can I use what dotPeek is showing me to learn what each line of code does? Finally, what am I missing that is keeping me from just taking the code I can see and recompiling it into a working program again (does that make sense)? Any and all discussion is welcome. Like I said, just poking around in the dark. [link] [comments]  | ||||||||||||||||||||||||
| Posted: 09 Jun 2019 02:03 PM PDT Hello, i just started learning to code and ive heard its very common for programmers to "dream in code". As someone who practices lucid dreaming I'm very curious as to what this means. Do you dream about coding on your computer or is it like that scene in the matrix where code is lining kn the walls? Id like a more specific description of what dreaming in code means [link] [comments]  | ||||||||||||||||||||||||
| How should I go about building this web app? Posted: 09 Jun 2019 03:12 PM PDT Disclaimer: I don't know jack shit about web development. I have an idea of what I want to do, and I just want to make sure I shoot in the right direction here when I start this project. This website is a really good example of basically what i'm trying to build. In writing, here's what I'm trying to do: I have a database full of security cameras and their IP addresses. These security cameras belong to a more general location (let's say there's 5 cameras in Chicago and 3 cameras in LA).
Here is what I have in mind: Create a web-app using python and Django. This will let me set up a lot of the ground work without doing much. Then I can create a camera table and a location table in the database. Next I would have to drop in a couple HTML, CSS, and JS files to get the front end. A couple of questions:

| Do trailing empty lines annoy programmers? Posted: 09 Jun 2019 10:42 PM PDT I add tons of new lines for easy clickability, it's habit now. Node design standards suggest erasing them.

| What resources do you use to code? Posted: 09 Jun 2019 12:04 PM PDT I am coding on a MacBook, trying to create some kind of window that will show a 3d render, something like minecraft. How do I get things like that started? I have made an android app before, but is this similar? What resources are recommended? how would I create a window to open up a game? What are different libraries and frameworks I could use? I am using Xcode to do my coding using c++. [link] [comments]  | ||||||||||||||||||||||||

| Posted: 09 Jun 2019 08:55 PM PDT I'm terrible at maths. I've been working on an IK solution to try and get more comfortable with using maths/angles in Unity. I've been able to made a CCD solution which works like this: https://www.youtube.com/watch?v=tZvdZGUxbbc But when I try to put angle constraints on the joints, I get some weird behaviour - shown here: https://www.youtube.com/watch?v=k1YY9KqqaYY I'm unsure why my constraints do not behave as intended and cause the rapid snapping seen. They also cause the solution to be innacurate (the heel no longer perfectly positions at the target). Here is my angle constraint code, scraped together from bits of advice etc: //clamp current joint rotation within set limits Vector3 currentJointEulerAngles = joints[i].joint.transform.localRotation.eulerAngles; if (currentJointEulerAngles.x > 180f) currentJointEulerAngles.x -= 360f; currentJointEulerAngles.x = Mathf.Clamp(currentJointEulerAngles.x, joints[i].XaxisMin, joints[i].XaxisMax); if (currentJointEulerAngles.x > 180f) currentJointEulerAngles.x -= 360f; currentJointEulerAngles.y = Mathf.Clamp(currentJointEulerAngles.y, joints[i].YaxisMin, joints[i].YaxisMax); if (currentJointEulerAngles.x > 180f) currentJointEulerAngles.x -= 360f; currentJointEulerAngles.z = Mathf.Clamp(currentJointEulerAngles.z, joints[i].ZaxisMin, joints[i].ZaxisMax); joints[i].joint.transform.localEulerAngles = currentJointEulerAngles; If anyone can explain/help me out here I would really appreciate it. Have been pulling my hair out for a full day now. If you need any more information I'll add it asap. Thanks everyone. [link] [comments]  | ||||||||||||||||||||||||
| Posted: 09 Jun 2019 01:20 PM PDT I have to make advising sheets editable in Excel(requiring the creation of drop-down menus, limiting errors and removing duplicate responses).
