A regex cheatsheet 👩🏻‍💻 (by Catherine)
let regex;
/* matching a specific string */
regex = /hello/; // looks for the string between the forward slashes (case-sensitive)... matches "hello", "hello123", "123hello123", "123hello"; doesn't match for "hell0", "Hello"
regex = /hello/i; // looks for the string between the forward slashes (case-insensitive)... matches "hello", "HelLo", "123HelLO"
regex = /hello/g; // looks for multiple occurrences of string between the forward slashes...
/* wildcards */
regex = /h.llo/; // the "." matches any one character other than a new line character... matches "hello", "hallo" but not "h\nllo"
regex = /h.*llo/; // the "*" matches any character(s) zero or more times... matches "hello", "heeeeeello", "hllo", "hwarwareallo"

Example of Parallelized Multipart upload using boto
#!/usr/bin/env python
"""Split large file into multiple pieces for upload to S3.
S3 only supports 5Gb files for uploading directly, so for larger CloudBioLinux

This parallelizes the task over available cores using multiprocessing.
Usage:
s3_multipart_upload.py <file_to_transfer> <bucket_name> [<s3_key_name>]
