How to setup a practically free CDN using Backblaze B2 and Cloudflare

⚠️ Note 2023-01-21
Some things have changed since I originally wrote this in 2016. I have updated a few minor details, and the advice is still broadly the same, but there are some new Cloudflare features you can (and should) take advantage of. In particular, pay attention to Trevor Stevens' comment here from 22 January 2022, and Matt Stenson's useful caching advice. In addition, Backblaze, with whom Cloudflare are a Bandwidth Alliance partner, have published their own guide detailing how to use Cloudflare's Web Workers to cache content from B2 private buckets. That is worth reading,

FASTBuild is an open-source distributed build system, which could be a free alternative to Incredibuild. Unreal Engine 4 (UE4) does not support FASTBuild natively, however it's not hard to integrate it manually.

Integrate FASTBuild with UE4

Install FASTBuild

We assume you already have the full UE4 source code. First you'll need to grab the latest FASTBuild tools from here. We use v0.93 Windows x64 version in this tutorial. Download it and extract all the files. Here you have several choices:

Place the files under any folder which could be found with your system's PATH environment variable. To see where these folders are, run the PATH command in a command prompt window;
Place the files under the Engine\Binaries\ThirdParty\FASTBuild folder of your engine. This is the recommended place;
Place the files anywhere you like. This is not recommended because you'll have to hard-code the path later.

	Resigning an iOS ipa for the app store

	Introduction

	Friday, October 18, 2019

	For the release of company iOS applications to the Apple app store we need to resign those apps with our appropriate distribution certificate. This is the process you need to follow, as-of-this-writing, to properly re-sign an foo.ipa to upload to Apple using the Application Loader.

	This writing is making the assumption that the foo.ipa bundle that you has been created appropriately and that is only needs to be resigned.

	import groovy.transform.Field

	// we want this to be global so that we can consistently
	// sync the same changelist over the course of our pipeline
	@Field currentChangelist = ''


	def riotP4Sync(Map config = [:]) {
	def humanReadableName = safePath("${JOB_NAME}-${STAGE_NAME}")
	def jenkinsWorkspaceName = safePath("${JOB_NAME}-") + workspaceShortname(env.STAGE_NAME)

	#!/bin/bash

	# This assumes that the ~6GB mojave installer is in the /Applications folder.
	# If it's not, just open the App Store, search Mojave, and you can download the installer file from there.

	hdiutil create -o /tmp/mojave.cdr -size 6g -layout SPUD -fs HFS+J
	hdiutil attach /tmp/mojave.cdr.dmg -noverify -mountpoint /Volumes/install_mojave
	sudo /Applications/Install\ macOS\ mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/install_mojave
	mv /tmp/mojave.cdr.dmg ~/Desktop/InstallSystem.dmg
	hdiutil detach /Volumes/Install\ macOS\ mojave
