I've come up with the following pattern that I would like to use within my domain. My question is more opinion then a single answer.
Use case.
Each domain service does one action called submit, a submit takes a Request, it uses the Requirements (validation and getting data) and then gives you ...
I am trying to learn Elixir, so I decided to write a port of Ruby's Parslet library.
I want to define a DSL that let's you define your grammar and given a string can parse it into an AST.
I wrote something... but it's not very Idiomatic. I'd love some pointers.
Also... I wanted to be able to...
How to run function and if result is not false push it to array?
I can think of:

var temp = getData();
if (temp) response.push(temp)
and

if (getData()) response.push(getData())
How to rewrite this to avoid temp creation or double function c...

I am developing a C++ kernel, and I've got the need for manipulating huge data structures before the task-scheduler runs - it means in non-preemptive environment. For this, I have developed a read-write serializer struct.
Its job is to allow readers to concurrently access the data. But any write...
I have been working on a project that uses python to access and fetch information from Jira. My question is is there a better way to implement this part which aims to fetch all the issues ?

In the following example, both the fp_t and the fn_t typedefs do their job just fine. The former defines a pointer to a function, the latter is a reference to a function. And both can be used to create a dispatch table, as shown.
Is there an argument for using one over the other?

I'm trying to find a more effective way to access variables within for loops, i felt that my attempt which works is not an effective way to access variables that are within for loops.

Goals:
So the plan was simple: Provide a factory to instantiate implementations of a certain interface (ModelConverter<T>), depending on what model-class you want to convert.
The approach is relatively straightforward:
statically map model-classes to ModelConverter implementations

I have the following JSON list of objects, and I'm able to find the required object, and pass it back to the caller, given the id. Everything works fine, I'm just wondering if there's a better (more efficient) way to return the node. I'm open to using a 3rd party tool like lodash.

A similar thread already exists (Custom maximumBy and minimumBy in Haskell), but in the Haskell Book exercises it also brings special cases that the custom maximumBy needs to satisfy:

Prelude> myMaximumBy (\_ _ -> LT) [1..10]

I added upon the Socket.IO tutorial, and wanted to know how I could improve my code. I have some questions about how it's built at the moment, especially when a client or the server should handle a task.
The app has the following features:

In this exercise, am trying to get an approach to think of a solution, for below question:
def twenty_eighteen():
"""Come up with the most creative expression that evaluates to 2018,
using only numbers and the +, *, and - operators.

2018

return ...
What I tried to do is compare arbitrary structures independent of the '==' operator implementation.
template<typename T>
bool bitWiseCompare(T a, T b)
{
size_t size = sizeof(T) / sizeof(char);
char* array_a = (char*)(&a);
char* array_b = (char*)(&b);

Say I want to write a multiplayer python game. I want to connect two computers that are in the same local network. I've succeeded using TCP/UDP connection and python sockets. Similar to python socket library example:
