I'm developing a API server in Go. My route handlers are becoming excessively long, especially when the response needs a lot of information.
For the following response type:
// StateResponse is queried by the client to get the entire initial
// database state.
type StateResponse struct {

This is a programming challenge I set for myself a while back to create an AI that starts with no knowledge of anything whatsoever, and learns as you talk to it. (It can learn stuff like your name, how to say hello, goodbye, etc.)
I tried to use the least amount of hard-coded responses as possib...
I wanted to practice using templates since I have no experience with them, so I implemented these sorting algorithms.
Selection Sort:
template<typename Container>
void selectionSort(Container& numbers)
{
for (auto iter = std::begin(numbers), iterEnd = std::end(numbers); iter != iterEnd; ++...
I am trying to find all primes less than 2,000,000 and sum them together. My code currently takes 1'36" to run. Is there a faster way to get my solution?
The logic I am following in this code is make a list of all primes I have found. Then check that every odd number less than 2,000,000 is not d...
I have been learning data structures and dynamic memory allocation in C. As a learning experience, I have written this linked list implementation. I really appreciate the feedback I've received on the previous code I've posted here and would love to hear any suggestions you all have on improvemen...
I recently began learning C# and I picked up Head First C# as a starting point. One of the first projects they have you build, without the code provided, is a racetrack betting app. The project first gives you the requirements, as well as some suggested implementations. I did not follow the sugge...

My Java code is as below.

I am using .NET Core 2.2, EF Core and C#. I have created a web API project.
I was requested to do an Upsert (insert or update). The entities structure is:

In this code I have declared myPushData, myPushDataFilterd and myPushDataFilterd2 variables which are using in code. I am thinking this code could be more easy & short

var myPushDataFilterd2 = new List<push...
2019 is here! And with the new year, as usual, comes a new iteration of Community Promotion Ads! Let’s refresh these for the coming year :)

Community Promotion Ads are community-vetted advertisements that will show up on the main site, in the right sidebar. The...
I tried my hand at making a numbered line list.
I would like some feedback on my use of CSS and if this approach (using a numbered list) is considered a good solution.

width: 70em;

I have a function solving a differential equation system. I want to plot one of the result variables (theta_i) after the system is solved. This variable comes from the equation:
np.arctan2(g1,g2)
so its values suppose to be between -pi and pi. If I print theta_i right after its calculation (in...
I made this code because, I figured that it might be an interesting concept, and that it would be nice to see it work. It enables the toggling of strict mode in any string of code.
It even allows you to set a scope to run it through, although it does use eval.
Example:
toggleableStrict("var a...

I like to refactor my code base, especially the raw pointer implementation of a factory.
I found a lot of implementations of the factory pattern. Some of them still use raw or the deprecated auto_ptr. The implementation here is imho too complicated.
Are there any drawbacks in this implementat...
I'm just starting with QT and I'm a bit confused as to what would consist of a good SE practise. I have a simple widget which is structured like this:

I'm putting together an example for students where I would like to show how we can optimize even such basic algorithm like a binary search with respect to hardware. I do not consider threads. I wrote it in C++ and the whole example can be found here. I'm trying to show some examples of the prefet...
I use the following code to render non_form_errors and non_field_errors. It feels that this is repetitive and I wonder if you have any best-practices to write it better?

I'm confused about the following results about greedy and non-greedy regular expression in python:
The first case:

x = 'From stephen.marquard@uct.ac.za Sat Jan 5 09:14:16 2008'
y = re.findall('\S+@\S+', x)
print(y)
result is :

My brain is fried from looking from looking at this for so long. Is there a more efficient way to do this code block. We have the ability to use es6 code too if that helps.

Probably many people had to work with multithreaded applications with C++ and can understand how messy can be fine-grained locking of objects.
So once in a while I came to idea of implementing some proxy objects using a so-called "drill down" property of operator-> and RAII in mind.
Yes. There ...

Yes, they do. They will also delete likes, as well.
However, the comments quoted and the general complaints on that video about dislikes going away are based on the claim that Gillette is either paying YouTube to delete dislikes, or that Gillette is doing it, itself.
One reason why YouTube dele...
