Unary operators

(and the oddities of number evaluation in JavaScript)

Type conversion, typecasting, and coercion are different ways of, implicitly or explicitly, changing an entity of one data type into another. [--wikipedia][wikipedia]

Unary operators, or "typeof +'foo' === huh?"

Cryptographic Best Practices

Putting cryptographic primitives together is a lot like putting a jigsaw puzzle together, where all the pieces are cut exactly the same way, but there is only one correct solution. Thankfully, there are some projects out there that are working hard to make sure developers are getting it right.

The following advice comes from years of research from leading security researchers, developers, and cryptographers. This Gist was [forked from Thomas Ptacek's Gist][1] to be more readable. Additions have been added from

Utiliser un SSD MVNe dans un NAS Synology en tant que volume et pas en tant que cache

Objectif final :
Déplacer le dossier docker, et le paquet Docker sur le volume SSD NVMe pour gagner en fluidité. Voir §-III. à la fin de ce GIST.

Note :
Les commandes suivantes sont pour la plupart à lancer en root dans un terminal, pensez à faire un : sudo -i

	# Haproxy configuration for SSL request passthrough to different backend based on SNI read from Handshaking stage
	# The Loadbalance will not decode the encrpted data but transparently transfer to the backend server in Private subnet.
	# With such configuration, you can install multiply services with its own SSL certificate in backend in different EC2 instance, but only explosure to public internet with one Loadbalance IP. There is no need to install SSL certificate in Loadbalancer level.
