Basic collision detection via ray casting in Unity.
public class BasicEntityCollision : IEntityCollision {
private Vector3 size;
private Vector3 center;
// Give a bit of space between the raycast and boxCollider to prevent ray going through collision layer.
private float skin = .005f;
private LayerMask collisionMask;
private LayerMask playerMask;
public bool OnGround { get; set; }

My largest Sidekiq application had a memory leak and I was able to find and fix it in just few hours spent on analyzing Ruby's heap. In this post I'll show my profiling setup.

As you might know Ruby 2.1 introduced a few great changes to ObjectSpace, so now it's much easier to find a line of code that is allocating too many objects. Here is great post explaining how it's working.

I was too lazy to set up some seeding and run it locally, so I checked that test suite passes when profiling is enabled and pushed debugging to production. Production environment also suited me better since my jobs data can't be fully random generated.

So, in order to profile your worker, add this to your Sidekiq configuration:

import tensorflow as tf
import numpy as np
import matplotlib.pyplot as plt
import pandas as p
