boto3 quick hands-on

This documentation aims at being a quick-straight-to-the-point-hands-on AWS resources manipulation with [boto3][0].

First of all, you'll need to install [boto3][0]. Installing it along with [awscli][1] is probably a good idea as

[awscli][1] is boto-based
[awscli][1] usage is really close to boto's

Simple, semi-anonymous backups with S3 and curl

Backing stuff up is a bit of a hassle, to set up and to maintain. While full-blown backup suites such as duplicity or CrashPlan will do all kinds of clever things for you (and I'd recommend either for more complex setups), sometimes you just want to put that daily database dump somewhere off-site and be done with it. This is what I've done, with an Amazon S3 bucket and curl. Hold onto your hats, there's some Bucket Policy acrobatics ahead.

There's also a tl;dr at the very end if you just want the delicious copy-pasta.

Steps to migrate from SVN to GitLab

This process worked for me. I take no responsibility for any damage or loss incurred as a result of following or not following these steps or, for that matter, anything else you might do or not do.

Setup

SVN is hosted at svn.domain.com.au.
SVN is accessible via http (other protocols should work).
GitLab is hosted at git.domain.com.au and:

This script is NOT MAINTAINED

This snippet of code was posted in 2014 and slightly revised in 2016 and 2017. It was more of a quick'n'dirty script than a polished tool. It is made only for Linux and in Python 2, which has since become outdated.

I currently do not use it, and I suggest you avoid it as well. Please do not expect support for using this script.

🔥 If you need an alternative, @glaucocustodio has kindly suggested EasyVPN in this comment.

The rest of the README is left for historical purposed.

The introduction to Reactive Programming you've been missing

(by @andrestaltz)

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

ANNOUNCEMENT

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

	# Simple [boto3](https://github.com/boto/boto3) based EC2 manipulation tool
	#
	# To start an instance, create a yaml file with the following format:
	#
	# frankfurt:
	# - subnet-azb:
	# - type: t2.micro
	# image: image-tagname

	import Data.List
	import Data.Function
	import Control.Monad

	groupOn f = groupBy ((==) `on` f) . sortBy (compare `on` f)
	uniq = map (!! 0) . groupOn id

	-- 场景：假设a得到了数字x，b得到了数字y
	-- 可看做二分图，其中possibleX，possibleY是顶点，possible是边，(aGuessY x)和(bGuessX y)分别表达x点和y点的邻接点集
	possibleX = [4..198]

	### AWS scripts
	These look trivial

	### Diamond
	Diamond is fairly popular and it looks like there's a built in way for Diamond to send metrics to AWS CloudWatch so maybe this is fairly easy
