Building Bazel for aarch64

I am building bazel for aarch64 on Amazon A1 platform. This flow is pretty nice and much easier than the QEMU flow which is prone to QEMU bugs.

Requirement

• An Amazon A1 platform running Ubuntu 18.04.

# Example uses GDELT dataset found here: https://aws.amazon.com/public-datasets/gdelt/
# Column headers found here: http://gdeltproject.org/data/lookups/CSV.header.dailyupdates.txt

# Load RDD
lines = sc.textFile("s3://gdelt-open-data/events/2016*") # Loads 73,385,698 records from 2016
# Split lines into columns; change split() argument depending on deliminiter e.g. '\t'
parts = lines.map(lambda l: l.split('\t'))
# Convert RDD into DataFrame
from urllib import urlopen
html = urlopen("http://gdeltproject.org/data/lookups/CSV.header.dailyupdates.txt").read().rstrip()

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

What's an Effective Engineer?

wojteklu

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.

Design rules
