| CS/Programming books for some light reading? Posted: 21 Jun 2019 08:00 PM PDT So this might be a bit of a paradoxical question, but I'm wondering if you guys have any recommendations for a CS/Programming book that might be a bit more fun to read and doesn't require heavy analysis. Just something to enjoy while relaxing. [link] [comments]  |
| [C++] Just learned how to use pointers. But why use pointers in the first place? What's the point? Posted: 21 Jun 2019 11:30 PM PDT What's the practical usage for pointers in the first place? It seems I can write any kind of program just fine without having to resort to pointers. So what if a pointer variable can store the address of something? Why would I practically need that?

| if/else/else if error : expected a statement Posted: 21 Jun 2019 10:48 PM PDT #include <stdio.h> int main(void) { sum = sum + 4; sum = sum + 3.7; sum = sum + 3.3; sum = sum + 3.0; sum = sum + 2.7; } The last 6 else if and else made an error What is WRONG? [link] [comments]  |
| Finding CS50 very difficult..other resources? Posted: 21 Jun 2019 04:37 PM PDT I generally consider myself fairly intelligent but I'm on week 2 of CS50 and I've listened to the lectures and short vids multiple times. I've googled a lot and still have difficulty with the problem sets. I am very determined to learn this stuff. But would it be detrimental to just continue the course even though I don't fully understand enough to complete the problem sets? I imagine the content builds on prior material so moving forward may make me even more lost? What other online resources can you recommend to supplement the course material to help me get through the problem sets without too much frustration? [link] [comments]  |
| What is the best music to code to? Posted: 21 Jun 2019 06:50 PM PDT I usually try listen to mellow instrumental stuff like Emancipator but I'd like to get more variety. [link] [comments]  |
| Posted: 21 Jun 2019 04:26 PM PDT I come from a non-coding background. I joined a computational lab to gain some experience related to my subject matter (science related). It started off great, but as I started to provide more results, the tasks and objectives set out for me became harder. Since I really don't know a thing about coding, I was trying to catch up on the basics, but ultimately I had to rely on stack overflow and borrowing other people's code to implement what I needed to do due to time constraints. Now I'm at a level that Google and Stack overflow won't cut it. Even when there is a related article that provides the code, the code is pages long and I don't have the faintest clue what it means (and they never define their variables!). I end up spending all day looking up packages, commands, terminology, dependencies, and etc for a piece of code online only to eventually give up or find out that an important function is deprecated. At this point, it's been months of me sitting in front of a computer feeling like I'm completely useless. I literally have accomplished next to nothing these past few months. I was learning so much at first, but now I'm leaving each day so frustrated at my complete inability to figure anything out. It's not just that I'm not producing results, it's that I'm literally learning nothing as I sit here hopelessly google, hoping that someone has an answer. I have guidance, but it's more guidance telling me what to, not how to do it. I'm really frustrated guys. I've been going home for months every night feeling like I'm a complete idiot. Is there any advice on how to deal with this frustration and any advice on how to figure problems out that's not just googling stack overflow and crossing my fingers? At this point, I will spend hours upon hours everyday working on a problem and accomplish absolutely nothing. [link] [comments]  |
| How do people learn to write elegant code? Posted: 21 Jun 2019 02:45 PM PDT I've been learning to program for a few months, and I'm kind of getting bogged down with a problem here. I feel that it's valuable to write elegant and concise code. To use fewer variables, write fewer lines, use fewer functions. Sometimes I end up checking a variable in a loop statement, then in an if statement in the loop for the same thing, then in a return statement too. I don't want to write code like that. But I don't know how people get to that point, though. Do I slow down my programming output and spend extra time trying to make each program as concise as possible--is this like a relatively finite skill where you learn a few patterns for writing more concise code that will repeat themselves through many different programs? Or do I just write "free form", write the first thing that makes sense without trying to simplify it and through a larger coding output I'll just kind of pick up best practices and my code will start getting more elegant without me having to specifically focus on it?

| Posted: 21 Jun 2019 06:43 PM PDT Hey everyone, I am going to start an internship next week and they just emailed us about some of the tasks we will be doing, and the first one I am assigned is "Perl to .net migration" and I have spent some time learning Perl, and understanding the basics of .net framework but whenever I try to learn about how to go about migrating perl to .net all I find are results about people looking for automated tools and nobody really talks about how to go about doing it. So I was wondering if anyone knew of any resources that I could learn from, or even had any idea why we would be doing this task at a higher level so I can understand why it is important to be doing this migration in the first place. I know I can just ask my manager and they will teach us all this when we start, but knowing a bit before I start will make me feel more confident. Thanks to everyone who responds! tl;dr how do you do Perl to .Net migration and why is it useful? [link] [comments]  |
| Posted: 21 Jun 2019 04:15 PM PDT I've been slowly learning C# and made my way through this series recently. I was planning on subscribing to DevU as I really enjoyed this intro but it appears there was a recent change to Bob Tabor's videos and there's completely different content on his site linked here. Is anyone familiar with these new ones and think they're worth it for a beginner since his departure from the DevU branding? [link] [comments]  |
| What Text editor/ IDE do you use and what plugins/extensions Posted: 21 Jun 2019 10:07 PM PDT I use Sublime text for everything else and Intellij Idea for my java but I was wondering what others use to do their coding [link] [comments]  |
| Is Go really worth learning if my goal is job now? Posted: 21 Jun 2019 08:44 PM PDT I prefer C#, and feel that it's the best fit for me as a programmer, as I can do whichever kind of programming I want with it. That doesn't mean I'm completely married to it. I have seen a lot of gushing talk about Go, mostly from people who work with the language. So is it worth learning if my current goal is to get a programming job? I'm trying to find work in web development. [link] [comments]  |
| How to set TimePicker in Preference in Android Studio Posted: 21 Jun 2019 08:41 PM PDT Hi I am a beginner in Android Studios and am currently trying to make a settings page on my app using preferences. I have read some tutorials online such as this https://stackoverflow.com/questions/5533078/timepicker-in-preferencescreen which seems to be working. However, the documentation ( https://developer.android.com/reference/android/preference/DialogPreference ) states that the dialog preference class is deprecated. Should I still follow the tutorial I found that is using a deprecated dialog preference class? In addition, I would like the user to be able to see the time that was picked in the settings page. After picking the time, it will show the time picked in the circle drawn. https://imgur.com/a/eMYlnV4. Does anyone know how to do that? Thank you so much :))) [link] [comments]  |
| Posted: 21 Jun 2019 08:40 PM PDT Before I got a new PC, I had this handy program that would combine selected DLL, XML, + an EXE into a brand new, completely independent EXE. This made it really convenient for sharing, plus I liked the clean look of the folder. Does anyone know what this program is? It definitely had a GUI. [link] [comments]  |
| A bit confused on this section of Javascript on CodeAcademy. Posted: 21 Jun 2019 08:35 PM PDT Hey guys. So I've decided to try and learn code on my own and I started with Javascript on Codeacademy. I'm a couple of weeks in and I'm on the section dealing with Comparison Operators. The exercise is this: Using let, create a variable named hungerLevel and set it equal to 7. 2. Write an if...else statement using a comparison operator. The condition should check if hungerLevel is greater than 7. If so, the conditional statement should log, 'Time to eat!'. Otherwise, it should log 'We can eat later!'. After you press run, play around with the condition by tweaking the comparison of hungerLevel by using different operators such as <=, >=, >, and <. This is my code: let hungerLevel = 7 if (hungerLevel > 7) {console.log('Time to eat!');} else {console.log('We can eat later!');} However, when I run it, I'm supposed to get 'Time to eat!', right? But the else statement shows up instead. Also, I'm trying to play around with by setting hungerLevel >= 7 or < 7 on a new line, but it's not working with the if else statement. Not sure what's going on here. Any help? [link] [comments]  |

| How to program my house in vr?? Posted: 21 Jun 2019 06:59 PM PDT I don't even know if this is the right page to ask or if it's even possible but if anyone could help or point me in the right direction please? [link] [comments]  |
| How to write device drivers for Mac? Posted: 21 Jun 2019 06:46 PM PDT I recently purchased an Xbox One controller which came with the Xbox Wireless Adapter to connect multiple controllers wirelessly. Unfortunately it seems to only work on Windows. I'm interested in seeing if/how I could write a device drive for Mac to utilize this dongle. Any chance anyone has any resources for how to write device drivers for Mac? (Also open to info about Linux drivers, but that's not my primary focus here.) [link] [comments]  |
| Why is O(n^2) called quadratic and not exponential? Posted: 21 Jun 2019 10:57 AM PDT Learning about log base 2 of n and it's logarithmic and it seems to be the opposite of exponents, because it divides in half instead of expanding exponentially. To me O(n^2) would be exponential O(log n) is logarithmic [link] [comments]  |

| Thoughts on Berkeley CS 61A? Comparison to MIT 6.00.1? Posted: 21 Jun 2019 12:20 PM PDT I've been wanting to take a CS course for a while, and would like to pick up Python along the way (at work we are finally moving away from Excel as our main data analysis tool, and are moving towards more powerful tools like Power BI, which supports Python. Plus Python is just generally useful). Long term I would like go deeper into data analytics or move into web / native app development (react native / electron / whatever hot JS framework will be out when I get there) - kind of still undecided at this point. I'm considering going through CS 61A, but it doesn't seem to be discussed much. Usually I see MIT 6.00 (or CS 50) recommended, but never CS 61 -- not really sure why (maybe just because it's not on edX? Or is there something I'm overlooking ? Is 6.00 the better course?) Has anyone completed CS 61A and what were your thoughts? My impression is CS 61 goes a bit deeper into Python (even though it's not a Python course) than 6.00 and is more focused on design of large scale projects but not much on data science, while 6.00 doesn't go deep into Python but focuses more on data science and algorithms. Is that accurate? [link] [comments]  |
