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)

Prerequisites

This guide applies to UEFI systems with GPT drives. It was tested on Windows 10 April 2018 edition, but it should also work on Windows 8 and newer releases (maybe even 7).

The problem

Occurs after an original drive from which the system drive was cloned is connected to the system at boot.

Error code 0xc000000e with message The boot selection failed because a required device is inaccessible.

Indexing

By default, simply adding the call 'searchkick' to a model will do an unclever indexing of all fields (but not has_many or belongs_to attributes).

In practice, you'll need to customize what gets indexed. This is done by defining a method on your model called search_data

def search_data

How to upgrade to Purescript 0.12

Before we begin, the type search in Pursuit is a great way to search for the functions you need.

Reset your tooling by deleting the bower_components/, .psci_modules/, .pulp-cache/, .psc-package/ and output/ folders. Then run psc-package build --only-dependencies.

Import changes and effects

Using sed or your other favourite global replace tool to search and replace all occurences in the list

	//Add following lines of code to exclude the files & folders which aren't important for watchers to look for changes...
	{
	//exludes fies & folders in search indexing
	"search.exclude": {
	"**/node_modules": true,
	"**/bower_components": true,
	"**/env": true,
	"**/venv": true
	},
	//exludes fies & folders for watcher service

	I was drawn to programming, science, technology and science fiction
	ever since I was a little kid. I can't say it's because I wanted to
	make the world a better place. Not really. I was simply drawn to it
	because I was drawn to it. Writing programs was fun. Figuring out how
	nature works was fascinating. Science fiction felt like a grand
	adventure.

	Then I started a software company and poured every ounce of energy
	into it. It failed. That hurt, but that part is ok. I made a lot of
	mistakes and learned from them. This experience made me much, much

	#!/usr/bin/env python
	import sys, os, time
	import tweepy
	keys = dict(
	consumer_key='_YOUR_CONSUMER_KEY',
	consumer_secret='_YOUR_SECRET_KEY',
	access_token='_YOUR_ACCESS_TOKEN',
	access_token_secret='_YOUR_ACCESS_TOKEN_SECRET'
	)

	========================================================
	= BACKSTORY
	========================================================
	I got a new SSD for my windows 10 home desktop computer recently. I used macrium to clone the HDD -> SSD and changed bios to boot from SSD.
	But when I tried cleaning the HDD I somehow corrupted something in the windows boot process (no idea how it happened, I never even touched my SSD).

	When I start windows I get error code 0xc000000e (A required device isn't connected or can't be accessed), so I have to go into recovery mode.

	Most people online fix this by using bootrec, or worst case scenario bootsect. Nothing works for me.

	if (location.protocol === "http:") {
	location.replace(window.location.href.replace("http:", "https:"));
