| Posted: 16 Mar 2019 06:40 PM PDT So, I'm currently working on an online game and have come up to a dilemma. Do I save player character data to a database, or to an XML file? I was originally going to save to an SQL database, but now that I've reached the point of implementation I've started to wonder what would be best. I'm not going to need access to character data without the main server, so being able to query off-site and independently isn't necessary. Plus, being able to directly load into object seems as though it would be easier. I can't find any information on peoples' opinions on this or industry standards. So, to elaborate on my question; [link] [comments]  |

| do Something if condition is met VS do nothing if condition is not met Posted: 16 Mar 2019 09:21 PM PDT I'm currently working on a java project, where a user is asked if he wants to save an image and if he wants to override it, if the file already exists. Now i've got a couple of approaches and dont know which one to use. Approach 1 (save Image when conditions are met):probbaly the easiest one to read, but: I'm calling saveImage() twice and if i would add more conditions, it would become very nested Approach 2 (stop if any conddition isnt met; saveImage at the end):looks less bulky, but worse readability using return statements in my opinion Approach 3 (saveImage is part else-block [when user wants to save the Image]): additional else makes it more clear that saveImage is only called when the first dialog is corfirmed Approach 4 (Mixture/best of both worlds?)has the benefit of approach 3 while loking less bulky I would probably use approach 2 or 4. what do you think is the best approach in this situation and why? in which situations would you do itdifferently and why?

| Question about programing an app that use NFC feature Posted: 16 Mar 2019 06:46 PM PDT Hello reddit, I am currently trying to develop an app that use the NFC technologie. Basicly, the app will receive an excel file via the NFC feature. The app will use the data in the file so the user will be able to filter the data and keep a track on it. I am trying to develop this app by myself. I have basic knowledge with C language. I need you guys to advise me on how I can make this project possible. What kind of software can I use for the programation? What steps do I need to follow to make it work? Thank you (Sorry for my poor english. It's my third language) [link] [comments]  |
| Help with Strand Sort algorithm in C++ Posted: 16 Mar 2019 05:21 PM PDT I have to implement Strand Sort in C++. But the caveat here is, that I MUST use arrays. No lists, linked lists, vectors, etc. allowed. Can anyone please help me out? I'm starting to lose my mind because I don't know how to implement this whole thing. Thanks in advance.

| Help needed with 32 bit to decimal converter in Python Posted: 16 Mar 2019 02:14 PM PDT I'm very new to programming and was recently assigned to create a python program that takes a raw 32 bit input from the user and returns a dotted decimal equivalent. I've attempted to ask for help from my peers and instructor but my peers haven't been able to explain the process to me simply enough while my instructor isn't even sure how to accomplish the task himself! (The school has had some budget cuts). The instructions for the assignment are as follows: Write a program in Python to read a 32-bit integer and output its corresponding value in dotted decimal notation. For example the number 10000000111111110000001100001111 would become 128.255.3.15. If this is the wrong place to be asking for this sort of help I apologize. I'm pressed for resources and time so any help would be amazing! [link] [comments]  |
| Looking for advice on how to construct something on a website Posted: 16 Mar 2019 10:06 AM PDT I'd like to build a similar website to https://jscompress.com However, the function will be completely different. All It does is to allow the user to uploads text files, and the program compiles all the text files into a single text file, which the user can download. How should I go about doing this?

| Use AWS Cognito to Sign In User - Xamarin Cross Platform Posted: 16 Mar 2019 12:20 PM PDT Hello folk, I have implemented this code to register an user to my AWS Cognito Pool Sign Up Code and it runs ok. But when trying to log in the user with Sign In Code it crashes my app when using a correct user ( usuario) /password (senha) combo. If I let the password field blank it returns me an error with the try/catch ~thing~. Is there anything that I`m missing here? [link] [comments]  |
| Question about Binary Search (i am using python) Posted: 16 Mar 2019 08:29 AM PDT Okay, so this is more an algorithmic question than a programming question per se, i think i understand how a binary search works. However, i am doing a problem set from Rosalind.info and the question says ProblemThe problem is to find a given set of keys in a given array. Given: Two positive integers n≤10^5n≤10^5 and m≤10^5m≤10^5, a sorted array A[1..n]A[1..n] of integers from −10^5 to 10^5 and a list of m integers −10^5≤k1,k2,…,km≤10^5−10^5≤k1,k2,…,km≤10^5. Return: For each kiki, output an index 1≤j≤n1≤j≤n s.t. A[j]=kiA[j]=ki or "-1" if there is no such index. Sample Dataset5 6 10 20 30 40 50 40 10 35 15 40 20 Sample Output4 1 -1 -1 4 2 I understand that a binary search basically will take the list A[1...n] and a value to search for k. it will take A[n/2] and check it against k, if it is bigger than k it will recurse the upper half of the list, if it is lower than k it will recurse the bottom half and will keep doing this until it finds the value in the list. From looking at the sample dataset, i understand that the bottom list 'm' is being compared to the top list and returning the index location. what i dont understand is what the purpose of the 5 and 6 are. They seem to be the length of the two lists, but is that necessary in the code? I really appreciate any help. I would have post this on Stackoverflow but i am trying to get to 15 rep and this seems like a question that the group would downvote to hell, considering they did one of my questions that i posted asking about why my output on a program i wrote was wrong.

| Download modpack for game using WebClient C# Posted: 16 Mar 2019 04:21 AM PDT Hello out there. I'm currently attempting to create a launcher that allows to download a modpack using the WebClient. However I have a problem in regards to check if the user is missing specific files, have been updated since or been delete since last check. What would be the easiest way for me to accomplish this? Perhaps I should use something else than WebClient? [link] [comments]  |
| Windows filesystem manipulator Posted: 16 Mar 2019 08:25 AM PDT I want to write a program that lists out all the subdirectories of a folder and when I press a button on one of those list items, it copies the files inside to another directory (overwriting what's already there). I also want to keep track of some data related to each subdirectory in the list (like in an excel format) which is simple text that I will manually be adding/changing. My question is which programming language would be best to accomplish this? Platform: Windows Research: I think this would be possible with excel and VB but not sure if it is or if it's the best [link] [comments]  |

I want to know, in this code, do i need to set class method that append all of this divs like i wrote, or there is a better way? [link] [comments]  |
| How do you increase the step count for a constexpr function? Posted: 16 Mar 2019 03:57 AM PDT I have a mapping function I have a function, I have tested this for all
Is there a way to change the compiler step size in Xcode? I want to add that I have simplified this in that there are actually 128 magic numbers for 128 hashtables. The compiler is happy to produce 49 of these before it gives up. [link] [comments]  |

| Attach external debug console to JavaWS applciation Posted: 16 Mar 2019 06:33 AM PDT I've got a JavaWS application for which I don't have ready access to the original source code (aside from decompiling). I'm looking to add some debugging functionality. Ideally this will be in the form of a console window which outputs where the code currently is (class and method name) as a user navigates through and interacts with the application's GUI. I'd need to be able to isolate this to a specific package so as to avoid spam of native java output. My main question is, is this possible? My understanding is the JVM is closed off but there are ways to interact with it by attaching things such as additional .jar files to it via command line arguments. This could contain an application that monitors for certain things and could provide output? I've also found stuff about the JNI however I'm still trying to get my head around how that works and whether or not it is appropriate for what I'm trying to achieve. [link] [comments]  |
