##How to check file integrity with shasum

For verifying the integrity (but not authenticity of data, i.e., who authored it or the origin of the file) of a file, it is necessary to run a checksum function on the file which will output a value and compare it to a previously stored checksum value; if it matches we can be relatively confident that the file hasn't been tampered with or altered.

You might be asked to verify a file's sha1sum or sha2sum–all this means is calculating and verifying the cryptographic sha1 or sha2 hash value or digest included in the file.

###Various commands and methods for verifying shasum 1 or 2:

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

	================================
	# Aggregating up requests per second that has a path label:
	- record: instance_path:requests:rate5m
	expr: rate(requests_total{job="myjob"}[5m])

	- record: path:requests:rate5m
	expr: sum without (instance)(instance_path:requests:rate5m{job="myjob"})
