EC2 Instance Connect meets AWS Session Manager via SSH

Both things have been introduced recently, and let you access even private ec2 instances

Without VPN
No open SSH port
Authentication / Authorization is fully delegated to IAM

# Assumes valid AWS Credentials in ENV

This gist lists challenges you run into when building offline-first applications based on IndexedDB, including open-source libraries like Firebase, pouchdb and AWS amplify (more).

Note that some of the following issues affect only Safari. Out of the major browsers, Chrome's IndexedDB implementation is the best.

Backing file on disk (WAL file) keeps growing (Safari)

When this bug occurs, every time you use the indexeddb, the WAL file grows. Garbage collection doesn't seem to be working, so after a while, you end up with gigabytes of data.

Random exceptions when working with a large number of indexeddb databases (Safari)

	Introduction
	============

	Futoshiki (不等式, meaning “inequality”) is a Japanese logic puzzle similar to
	Sudoku and the like. Numbers from 1 to n must be placed on an n-by-n grid
	(which usually already contains some values) such that each row and each column
	is a permutation of `[1..n]`. Additionally, less-than or greater-than signs are
	placed between cells, constraining their mutual ordering.

	An example puzzle looks like this:

	# install pip & virtualenv
	# create a virtual environment for your webapp
	# install django in the new virtualenv

	cd ~/tmp
	PYVE=2.7
	PYVER=2.7.3
	STVER=0.6c11
	# go directly to the source to get the latest and greatest
	wget http://pypi.python.org/packages/$PYVE/s/setuptools/setuptools-$STVER-py$PYVE.egg#md5=fe1f997bc722265116870bc7919059ea

	# Install python and some binary-dependencies from source in the user directory
	# useful for Django webapps on shared hosts like Dreamhost

	# BerkelyDB v 4.8 is supported by python 2.7 but not 5.3
	# In addition, the bsddb module was deprecated in Python 2.6 and will be removed in 3.0
	# So all this BDB stuff isn't useful, but does no harm
	# linuxfromscratch.com has patch that can make python 2.7 work with BerkelyDB, if you need it
	BDBVER=5.3.21
	BDBVE=5.3
