dev-opus / script.py

Created December 9, 2022 07:52

This Gist holds a Python script that was used in computing the Mass Attenuation Coefficient of samples used for my final year project work.

	import statistics as stat
	import math


	def computeIntensity(list):
	readings = [x * 1000 for x in list]
	intensity = stat.mean(readings) - bg_intensity
	return intensity

better error handling method for asynchronous javascript programming

	/*

	so uhm, up until about a week ago, my
	defacto method for handling errors in an
	async/await program-flow was to wrap my
	entire code-block in a try/catch; performing
	the operations in the `try {}` block and
	handling any errors in the `catch(err) {}` block.

	it worked well, but it didn't sit well with me
