I have polylines in a GIS database. The polylines are stored using a user-defined type called ST_GEOMETRY.
ST_GEOMETRY has lots of spatial functions. However, it does not have a polyline midpoint function.
Therefore, I have written a custom PL/SQL midpoint function.
As a novice programmer, I...
Was working on this problem and made some code that got the answer in 11 seconds average. How can I optimize this code to maybe work in under 5 seconds?

return int(n*(3*n - 1) / 2)

I'm working on a simple 2D tile editor in Angular 8 like this:
The tiles are represented as objects in an array.
Clicking on a tile should update/replace the tile with a previously selected one.

Let d(n) be defined as the sum of proper divisors of n (numbers less than n which divide evenly into n).
If d(a) = b and d(b) = a, where a ≠ b, then a and b are an amicable pair and each of a and b are called amicable numbers.
For example, the proper divisors of 220 are 1, 2, 4, 5, 10, ...

I have modelled a series of school classes as follows.
The part I am not sure about is having a separate table for cancellations and substitute instructors.
With this setup every time you looked up the class schedule for a given week you would have to search the class_exceptions table in order ...

This code will generate a pseudorandom alphanumeric string of given length.
I would welcome suggestions on how to make it more random. Beyond that, have I made any convention violations, Exception cases, and the like?
Also, is there any way to make it faster?

I've written a lock-free state machine in go and I would love to receive some feedback on it.
Writing this library my main concerns are keeping it lock-free and very light-weight (no bells and whistles like hooks and such).
Because this is lock-free I had to use atomic.CompareAndSwap which mean...I'd like to know there's a better code than I did.

itemId: string;

I need to implement Dijkstra's algorithm on ROS.
(You can ignore the ROS part, that is not important as this moment.)
So, I have a map of 1000x1000 pixels which I have converted into a row-dominant matrix for this problem.
We start off by creating a structure node for the priority queue which I...

Python's Abstract Base Classes in the collections.abc module work as mixins and also define abstract interfaces that invoke common functionality in Python's objects.
While reading the actual source is quite enlightening, viewing the hierarchy as a graph would be a useful thing for Py...
Somewhat simplified task is to efficiently extract about a 250,000 user records from a mariadb and do some string munging and then find the "TopN" (eg most common firstnames, etc) for 3 fields.
Focus is on performance (real life case is bigger). Focus is firstly on algorithm: I think the unorde...
