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.

Getting Started

The following command will install the latest version of REX-Ray to /usr/bin/rexray on Linux systems:

$ sudo apt install s3fs
$ curl -sSL https://dl.bintray.com/emccode/rexray/install | sh

Depending on the Linux distribution REX-Ray will be registered as either a SystemD or SystemV service.

Configure

REX-Ray requires a configuration file for storing details used to communicate with storage providers. This can include authentication credentials and driver specific configuration options. After REX-Ray has been installed, copy and paste the contents below to a new file on the host at /etc/rexray/config.yml to configure s3fs storage driver.

Go (Golang) Standard Library Interfaces (Selected)

This is not an exhaustive list of all interfaces in Go's standard library. I only list those I think are important. Interfaces defined in frequently used packages (like io, fmt) are included. Interfaces that have significant importance are also included.

All of the following information is based on go version go1.8.3 darwin/amd64.

Building Tensorflow from source on Ubuntu 16.04LTS for maximum performance:

TensorFlow is now distributed under an Apache v2 open source license on GitHub.

On Ubuntu 16.04LTS+:

Step 1. Install NVIDIA CUDA:

To use TensorFlow with NVIDIA GPUs, the first step is to install the CUDA Toolkit as shown:

In this article, I will share some of my experience on installing NVIDIA driver and CUDA on Linux OS. Here I mainly use Ubuntu as example. Comments for CentOS/Fedora are also provided as much as I can.

	#!/usr/bin/env zx

	// Establish program arguments
	const input = argv.i;
	const output = argv.o;
	const fadeDuration = parseInt(argv.f);
	const useTransparency = argv.t;
	// Quality options
	const bitRate = argv.b;
	const constantRateFactor = argv.crf;

	#!/bin/bash
	[[ ! -n $3 ]] && { echo "Usage: crossfadevideo <input.mp4> <fade in seconds> <output.mp4> [looptimes]"; exit; }
	input="$1"
	fade="$2"
	duration="$(ffprobe -v error -select_streams v:0 -show_entries stream=duration -of default=noprint_wrappers=1:nokey=1 "$input")"
	duration=$(echo "$duration-($fade)" \| bc \| sed 's/\..*//g')
	[[ ${duration:0:1} == "." ]] && duration="0$duration"
	output="$3"
	[[ -n $4 ]] && loop=$4 && output="${output}.mkv"
	set -x
