Introduction Want to access the Internet safely and securely from your smartphone or laptop when connected to an untrusted network such as the WiFi of a hotel or coffee shop? A Virtual Private Network (VPN) allows you to traverse untrusted networks privately and securely as if you were on a private network. The traffic emerges from the VPN server and continues its journey to the destination. When combined with HTTPS connections , this setup allows you to secure your wireless logins and transactions. You can circumvent geographical restrictions and censorship, and shield your location and any unencrypted HTTP traffic from the untrusted network. OpenVPN is a full-featured open source Secure Socket Layer (SSL) VPN solution that accommodates a wide range of configurations. In this tutorial, we'll set up an OpenVPN server on a Droplet and then configure access to it from Windows, OS X, iOS and Android. This tutorial will keep the installation and configuration...

NASA Climate Change Letter Belongs To Long Tradition Of Fake Expertise WASHINGTON -- When former NASA administrators, astronauts and engineers released a letter earlier this week attacking the science of climate change, its veneer of legitimacy kicked off a media blitz. Yet none of the letter's 49 signatories are climate scientists, and with more than 18,000 people currently working for NASA, to say nothing of the tens of thousands more who are retired, the letter seems more than anything like an empty publicity stunt, and one for which there's considerable precedent. "When you have an area of the science where there is a consensus like in climate change, where the problem is real and the scientific implications are on a collision course with vested interests like the fossil fuel industry, you often see this," said Michael Mann, a well-known climate scientist and Penn State professor. NASA has been clear that it firmly accepts the reality of the science...
