Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

== Overview of Datasets ==

The examples in this book use the "Chimpmark" datasets: a set of freely-redistributable datasets, converted to simple standard formats, with traceable provenance and documented schema. They are the same datasets as used in the upcoming Chimpmark Challenge big-data benchmark. The datasets are:

Wikipedia English-language Article Corpus (wikipedia_corpus; 38 GB, 619 million records, 4 billion tokens): the full text of every English-language wikipedia article, in
Wikipedia Pagelink Graph (wikipedia_pagelinks; ) --
Wikipedia Pageview Stats (wikipedia_pageviews; 2.3 TB, about 250 billion records (FIXME: verify num records)) -- hour-by-hour pageview

There are many situations on the browser client when it would be desirable to make an AJAX call to a web-site or web service to fetch data. Many a time, the data source is on a different domain than the one from where the request is originating. These are called cross-domain requests. All browsers discourage scripts from making cross-domain requests as they are wary of the security implications in allowing arbitrary data requests across trust boundaries. At Scibler, the browser plugin that gets activated on the google mail domain needs to request data from Scibler servers to create an integrated experience for a user.

Partial mitigation of 2 important attacks is a reason why browsers advocate the Same Origin Policy (SOP) for data requests. One is called XSRF or CSRF (pronounced sea-surf) and the other XSS.

[XSRF] (http://en.wikipedia.org/wiki/Cross-site_request_forgery) stands for Cross-site Request Forgery, where in, trust on a user's browser that is providing a session with a particular site is hi

The introduction to Reactive Programming you've been missing

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.

Strictly Frameworks

Mobiledoc - github.com/bustle/mobiledoc-kit - framework to build editors with a standardized JSON structure
ShareDB - github.com/share/sharedb - framework to sync any JSON document using operational transforms, add real-time collaborative editing to anything else
Bangle.dev - github.com/bangle-io/bangle.dev - toolkit built for building editors, based on prosemirror

Abstracted Editors

These use separate document structures instead of HTML, some are more modular libraries than full editors

	#!/bin/sh

	cd ~/Downloads

	echo ":::::::::: WGET"
	# install wget, which is cleverer than curl
	curl -O http://ftp.gnu.org/gnu/wget/wget-1.11.tar.gz
	tar zxvf wget-1.11.tar.gz
	cd wget-1.11
	./configure --prefix=/usr/local
