    Why don't non-compsci posts get removed?

    Posted: 20 Sep 2020 02:09 AM PDT

    I don't want to sound unappreciative, but I believe this sub is a disappointment for computer science enthusiasts and researchers. There's a lot of spam about cloud computing, devops, various libraries and frameworks, etc. by users like u/Techbiason, u/itbloggy, and others. Can we ban them? There is also a high volume of posts about programming or software engineering topics that are largely irrelevant to computer science. What's up with the low signal-to-noise in this sub? Are the mods stretched too thin?

    Obviously people can have differing opinions on what constitutes "computer science", but I wouldn't include things like "Review[ing] client's brand standards". Other subs seem to be more strict about only allowing appropriate content that adheres to the relevant standards. Is there anything we can do to make the content here more relevant to the name of this sub? Or are there so many members (1.1m!) that it's too hard to curate everything?

    I recognize that I have biases regarding what I consider to be "relevant", and I don't want to give off gatekeeper vibes. But surely I'm not the only one who thinks this sub could be improved by changing our posture on moderation.

    An Open Source Physics Simulations Project

    Posted: 20 Sep 2020 04:03 AM PDT

    I have assembled a team of physics students from Reddit two months ago and we have created an open source physics simulations project that aims to deliver clear and understandable simulations free for everyone. Please check out our project website here: https://physicshub.herokuapp.com/

    ​

    Also we have created some issues on our Github repository. If you want to contribute by coding simulations or writing theory sections, you can check out our Github repository here: https://github.com/ThePhysHub/ThePhysicsHub

    ​

    We have a Discord server for the people that are interested. You can join the server here : https://discord.gg/z4pPVKd

    ​

    Please take your time to create issues about your thoughts and suggestions about the project on Github.

    ​

    Thank you all for your interest!

    What is your opinion on domain vs business type structures?

    Posted: 20 Sep 2020 04:32 AM PDT

    I might be confusing the terminology, but it's basically:

    Controllers: 1,2,3
    Repositories: 1,2,3
    etc.

    vs

    1: controllers, repositories,...
    2: controllers, repositories,...
    3: controllers, repositories,...

    Is it dependant on the project? To me it make more sense to group parts of a unit together, than separate them based on type.

    How is OS thread different from hardware thread?

    Posted: 20 Sep 2020 03:47 AM PDT

    Let I have a 2 thread per core CPU with 4 cores. And I run my program is multi-threaded (let I have 16 different threads in my program). How will the program be executed? How much different will that be from a CPU which is just multi-cored and not have hyperthreading/multiple threads.

    Why not index instead of q.top()? (why not choose the matched ‘(‘ but the previous one?) [leetcode 32][dynamic programming]

    Posted: 19 Sep 2020 11:06 PM PDT

    Leetcode 32

    class Solution { public: int longestValidParentheses(string s) { stack<int> q; //LIFO int start = 0; int ans = 0; for (int i = 0;i < s.length(); i++) { if(s[i] == '(') { q.push(i); } else { if (q.empty()) { start = i + 1; } else { int index = q.top(); q.pop(); ans = max(ans, q.empty() ? i - start + 1 : i - q.top()); } } } return ans; } };

    if don't need index, why declare it?
