Alterantiva para quem usa o DNS da Google

A empresa gaúcha Cyberweb Networks, a mesma por trás da KingHost, lançou em 2009 o GigaDNS: a alternativa brasileira para o OpenDNS, o mundialmente famoso serviço de resolução de nomes de domínio, mas com a diferença de ter servidores localizados aqui no Brasil.
Com isso, o tempo de resposta fica bem menor e o acesso aos sites fica mais rápido. Um servidor DNS é o responsável por converter os domínios que costumamos acessar para algo que um computador possa compreender, o que no caso são os endereços IP. Você pode digitar google.com para fazer uma pesquisa, mas sem um servidor DNS isso não faria o menor sentido para uma máquina.

Como pegar a senha do Whatsapp de um Android ou Iphone

WhatsApp is a very popular SMS-like messenger for smartphones, but it’s unfortunately only available for smartphones right now. If you want to use other tools or write web applications that send or receive WhatsApp messages (e.g. WhatsAPI ), you have to find a way to sniff the WhatsApp password from your smartphone. Until recently, this password was just an MD5 hash of your IMEI (or MAC address), but that has changed when that was uncovered. Since then, the WhatsApp server assigns a password to each device/account when it first registers. This tutorial demonstrates how to capture the WhatsApp password of your WhatsApp account using the SSL/TLS proxy mitmproxy . Once you have this password, you can use it to communicate with the WhatsApp servers directly or via a framework. This is the first part of a two-part tutorial. The second part demonstrates how to send and receive WhatsApp messages via PHP . Contents Updates 1. Introduction 1.1. Please note:
