    Changing rendering library? Rewriting entire SAAS App?

    Posted: 21 Apr 2021 10:04 PM PDT

    I work for a SAAS company that has a product that has been having performance issues. They decided to rewrite the entire thing from using SVG to using a different fast 2D rendering library. I am not sure even what that means or what is involved here.

    Can someone explain what this generally means and involves? how can a project manager help with this process?

    Is there a ELIfreshman of why you use functional programming over OOP with some short poignant examples?

    Posted: 22 Apr 2021 01:19 AM PDT

    I am 12 years hobby programmer who can't even fathom how you would write code without thinking in OOP. I need like 1:1 examples problems and scenarios to understand. I think. Checked the FAQ and history too before anyone asks. I don't think anything specific with code just a bunch of ELI5 attempts to explain it.

    Suggest me to learn new technologies/ language

    Posted: 22 Apr 2021 01:17 AM PDT

    I am a fresher and joined very good company. Java is the main language used here. But it's been more than 6 months and I don't think I have had growth till now. Worked on some small enhancements and had trainings earlier and few when needed. Now I have been told to debug the applications to get the idea and flow since no other work is assigned. I am done with debugging and there is no other work. I have done a 1 year internship, worked on backend (Node.js) and have learnt a lot and was pretty confident, developed many important services . But now I am not in touch with node.

    As I am not feeling productive for a long time. Can you suggest some things which I can go on to learn. Or how can I start and what are the required skills and technologies in market which will be useful when I switch. What kind of project should I develop? I am eager to learn Full stack. Have no idea about front -end technologies and confused what to choose. Currently I know Java, Java EE and Node.js, Python (basics). Had done projects on Machine Learning. I love Node.js and Java not that much.

    It will be helpful if anyone of you will guide me.

    Learning JavaScript, threejs, and WebGL, where should I start?

    Posted: 22 Apr 2021 01:13 AM PDT

    I'm at the end of the accredited version of Harvard's CS50 course and I'm diving into JavaScript, HTML, and CSS for my final project. So I basically have as much knowledge as this course gives plus a little extra from some very basic research that I did on more compelling web graphics and interactions.

    I'm unsure yet if I'll take any of the extension school's web development courses yet but I definitely want to continue on this path on my own.

    What would be the best next-steps to take in order to head in the direction of WebGL and threejs kind of stuff? I have about three weeks to complete my final project, what is a resource or a course that I could start using now to aid in my project as well as my further education? Is SuperHi a good starting point? Or should I be looking at a course on udemy?

    Developing an app, but do not aspire to become an app developer.

    Posted: 21 Apr 2021 06:52 PM PDT

    I want to focus on becoming a software engineer in the future.

    Will developing an app help me develop my current skills (Currently learning data structures and algorithms) ? Or will it be a waste of time. This will be one of my first "big" (Only for the interest of my friend and I) projects , so I`m not sure.

    Any help will be appreciated. Thank you

    Text not perfectly centered with Flexbox

    Hi! I'm trying to center a title with FlexBox but it just seems to be a bit off.

    Here's my code:

    HTML ... <main> <div class="presentation"> <h1 class="main-name">Name</h1> </div> </main> CSS: ... .presentation{ display: flex; width: 90%; height: 90vh; justify-content: center; align-items: center; } .main-name{ text-align: center; }

    Struggling to Output Columns

    Posted: 21 Apr 2021 08:46 PM PDT

    I'm trying to output the ID, name, major, and GPA all on one line. I can output the ID and name or the major and GPA but not all of them together. This is the code I have currently:

    ostream & operator << (ostream & out, const Student & data) { out << setw(5) << left << data.id << setw(1) << data.name << setw(6) << data.major << setw(4) << data.gpa << endl; return out; } 

    This results in output that skips the ID and name and looks like this:

    PSYC1.85

    GREE3.25

    PHIL3.1

    GEOG3.37

    This overloaded << operator returns the output to a function that outputs the data from a Doubly Linked List. I believe the problem lies within the overloaded operator, but I will attach that function as well.

    template<typename TYPE> void DLList<TYPE> :: display() const { Node<TYPE> * pTemp = front; while(pTemp) { cout << pTemp -> data; pTemp = pTemp -> next; } } 

    From what I have seen online, the problem probably has something to do with the buffer, but flush doesn't work. Adding endl every time I output data works, but I need them to be on the same line.

    If anybody can help id be very grateful!

    EDIT: I've just realized that it will not output all of the data even without the setw. Still looking for a solution.

    Virtual Reality development | UNITY

    Posted: 22 Apr 2021 12:27 AM PDT

    Before you scroll and write me off like everyone does, hear me out. I'm specifically here to both inquire and advise others. For we who are completely new to coding, but want to jump into VR development directly, what are the best resources to get going NOW? No more tomorrows, no more maybe laters. Just strictly diving in NOW, and powering through all the way to a completes app or game that I can publish and have released into the Oculus Quest 2 store.

    Note: I am already a developer via Oculus account. I already have Unity installed and setup properly. I know about Unity Assets and importing them.

    I have never typed a line of code in my life. I have no knowledge of animations nor 3D modeling.

    Anyone else at this point too?💯🔥👽👌

    what is the most efficient way of finding the value of sub array element corresponding to the key of an object?

    Posted: 22 Apr 2021 12:08 AM PDT

    Hello,

    Considering this problem:

    const arr = [[a, b, c], [a, b, c, d],[b, d]] const obj= { a: 1, b: 2, c: 42, d: 13, ... } 

    what is the fastest/most efficient way of determining the value of each element in array that corresponds to the key name in object? I'm most familiar with js but i guess it would apply in most of the programming languages.

    How can I learn to improve my problem solving skills and understand coding better

    Posted: 21 Apr 2021 03:20 PM PDT

    I am interested in learning about programming so I have been thinking about some problems that I can solve on codewars and other coding websites. The problem with that is that I do struggle at times trying to translate the pseudocode into regular code. I just struggle with trying to make the algorithm into a way that the computer can understand it. I just need help trying to break down the problem and to solve it into the small basic steps that are important enough. Does anyone have any tips and advice on how to do this??

    What to do every single day to become a better programmer than the previous day?

    Posted: 21 Apr 2021 11:17 AM PDT

    Hi everyone, I am new to this community so forgive me if my question is not up to the mark.

    So I have been coding for past 3 years now. I have built projects and also solve data structures and algorithm problems. Now the problem I am facing is that my growth has been very slow over these years. What I mean by that is, I don't have a very deep understanding of how to write server code that is scalable, or what modern practices to follow, etc.

    Basically, the projects I have built have a simple architecture, like simple web apps, even though they all are different from each other, meaning they are all unique. I don't know much about how to improve the code to incorporate better tools and libraries.

    A more concrete example is dogehouse by Ben Awad. I have experience with React programming, but when I saw his repo on Github, I could barely understand the architecture. It was using so many different tools, components and libraries. How do I familiarize myself with such knowledge so I could write more complex and better solutions?

    I have the advice that one should learn by building projects. But how does one know if the project he/she has built could be improved? How to achieve deliberate practice?

    Finally, what can be done every single day to become a bit better?

    Edit: This was my first post here. I have recently started exploring communities on reddit. I am overwhelmed by the amazing response everyone has provided to this post. I really wish I could upvote every answer more than once!! Thanks a lot everyone.

    I have decided to build a project. It will be more like a proof of concept rather than a fully polished product. I will ask for feedback from you people here, on what can be improved in terms of architecture, code, tools, features etc. Then I will incorporate those and improve the app. I guess it could be a nice way for deliberate practice!

    I need a small program, but I haven't coded in 10 years. Just for quick reference comparison to help in musical key modulation.

    Posted: 21 Apr 2021 11:36 PM PDT

    Hello, I studied programming about 10 years ago before I quit. It wasn't that hard for me, but I didn't like many things about it, no point in getting into that now. For a while Ive been planning on doing a reference guide for, basically, comparing properties of classes, more specifically, comparing musical keys for modulation compatibility. The idea of making a program to do this for me almost always came with the original idea of writing out a guide. Well today I took to writing it out by hand and, it wont take THAT long, but I might as well just program it. It shouldn't be that hard.

    I learned Java, C, some C++, assembly, when I was studying this. What language would you recommend for something this seemingly basic? I am open to learning a new one if it isn't difficult or to far from these.

    I would prefer a very simple user interface as well. Classes seem like a natural thing to make this easier.

    My goal would be to have a drop down menu of what you want your first key to be. That would be A through G, then select the quality of the key, Mayor, Minor, or any other would be easy to add at this point (preferably with some way to limit what quality of chords to include in the 'search' results).

    Then, you would preferably get a list of keys ordered by the number of chords that are similar to the original, clarifying the degree of the chord in the original and destination key that are similar. For example: From A minor to E minor: 5(1), 7(3), 1(4), 3(6).

    The goal of this is that usually key modulations are explained reasonably well in theory, but then, all that is famous is the circle of fifths, a tool explaining that modulating to the fifth degree, like explained in the example. It is a strong idea, but you can do much more, hence my idea for this little tool, since the combination can be a ton.

    Any help in regards to this would be deeply appreciated.

    Today interview question at Google Singapore: Subarray Sum Equals K (Leetcode)

    Posted: 21 Apr 2021 11:36 PM PDT

    If you like, please give me stars at: https://github.com/leduckhai/Awesome-Competitive-Programming

    Problem description

    Given an array of integers nums and an integer k, return the total number of continuous subarrays whose sum equals to k.

    Example 1: Input: nums = [1,1,1], k = 2 Output: 2

    Example 2: Input: nums = [1,2,3], k = 3 Output: 2

    Solution

    ``` Function to find the number of continuous subarrays of an array whose sum equals to k. Time complexity = O(n)

    Parameters:


    nums: list The input array k : int Given sum of subarrays 

    Returns:


    count: int The number of subarrays 

    Examples:


    Given an array [3,4,7,2,-3,1,7] with given sum k = 7. Subarrays that have sum = 7 are: [3,4], [7], [7,2,-3,1], [2,-3,1,7], [7]. How the algorithm works? The array of cumulative sum is [0,3,7,14,16,13,14,21]. In the algorithm, turn the array into dictionary of cumulative sum and its frequency: memo = {0: 1, 3: 1, 7: 1, 14: 2, 16: 1, 13: 1, 21: 1} For every cumulative sum (called current sum), if (current sum - k) is in memo, then we found subarray(s) having sum = k from index of the sum = current sum - k to index of the current sum. The number of subarray(s) found is the frequency of the sum = current sum - k. i = 3 -> currSum = 3 -> currSum - k = -4 not in memo -> ignore i = 4 -> currSum = 7 -> currSum - k = 0 in memo -> count = 1, found [3,4] i = 7 -> currSum = 14 -> currSum - k = 7 in memo -> count = 2, found [7] i = 2 -> currSum = 16 -> currSum - k = 9 not in memo -> ignore i = -3 -> currSum = 13 -> currSum - k = 6 not in memo -> ignore i = 1 -> currSum = 14 -> currSum - k = 7 in memo -> count = 3, found [7,2,-3,1] i = 7 -> currSum = 21 -> currSum - k = 14 in memo -> count = 5, found [2,-3,1,7], [7]. >>> nums = [3,4,7,2,-3,1,7] >>> k = 7 >>> print(SubarraySum_EqualsK(nums, k)) 5 

    References: https://leetcode.com/problems/subarray-sum-equals-k/solution/ ```

    ``` def SubarraySum_EqualsK(nums, k): from collections import defaultdict

    memo = defaultdict(int) # Memoization as: Cumulative sum -> Frequency memo[0] = 1

    currSum = 0 # Current cumulative sum count = 0 # Number of continuous subarrays whose sum = k

    for i in nums: currSum += i

    # If (current sum - k) is in memo, then we found subarray(s) having sum = k # from index of the sum = current sum - k to index of the current sum. # The number of subarray(s) found is the frequency of the sum = current sum - k. if currSum - k in memo: count += memo[currSum-k] memo[currSum] += 1 

    return count ```

    API is incredibly slow to update information

    Posted: 21 Apr 2021 06:44 PM PDT

    I recently started hosting a website with an API. The api worked great when i ran it locally. While hosting it the POST requests are lightning quick at inserting data into my database. However the GET requests will usually just retrieve data that is 5 minutes old (I.e. there is a 5 minute delay between posting data and seeing the API retrieve it). The problem is not that the GET requests are taking 5 minutes, the GET requests run quickly it just takes them 5 minutes to realize new data has been added to the database. Any idea why this is happening?

    Edit: Issue has been solved, caching was enabled in my browser which caused the GET request to not check the updated database
