Build libcurl for android NDK

Libcurl requires openssl and zlib to be fully operationnal

Step 1 : cross compile zlib
Step 2 : cross compile openssl
Step 3 : cross compile curl with zlib/openssl external link

Prerequisites :

In this gist I would like to describe an idea for GraphQL subscriptions. It was inspired by conversations about subscriptions in the GraphQL slack channel and different GH issues, like #89 and #411.

Conceptual Model

At the moment GraphQL allows 2 types of queries:

query
mutation

Reference implementation also adds the third type: subscription. It does not have any semantics yet, so here I would like to propose one possible semantics interpretation and the reasoning behind it.

Docker Machine and VMware vSphere

Install govc go get github.com/vmware/govmomi/govc and go install github.com/vmware/govmomi/govc
export GOVC_URL='https://[USERNAME]:[PASSWORD]@[ESXI-OR-VCENTER-HOSTNAME-OR-IP]/sdk' and export GOVC_INSECURE=1 from govmomi (vSphere SDK for Go), govc CLI & Kubernetes on vSphere

# Key considerations for algorithm "RSA" ≥ 2048-bit

	# create an UDP server using nc on port 11090
	nc -ul 11090

	# check whether an UDP server is listening on 11190
	nc -vz -u <hostname> 11090

	# send a packet to the UDP server
	echo -n "hello" \| nc -4u -w1 <hostname> 1118

	package main

	type SomethingInterface interface {

	# post_loc.txt contains the json you want to post
	# -p means to POST it
	# -H adds an Auth header (could be Basic or Token)
	# -T sets the Content-Type
	# -c is concurrent clients
	# -n is the number of requests to run in the test

	ab -p post_loc.txt -T application/json -H 'Authorization: Token abcd1234' -c 10 -n 2000 http://example.com/api/v1/locations/

	To do so on terminal:

	gksu gedit /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla

	Replace gedit with your favorite editor’s command. This command will open a blank file. Copy and paste these lines:

	[Enable Hibernate]
	Identity=unix-user:*
	Action=org.freedesktop.upower.hibernate
	ResultActive=yes

	#!/bin/sh

	curl -XPOST -H "content-type:application/json" -d '{"hoge": 1, "fuga": [2,3,4,5]}' localhost:1323
