Using SSH keys for Password-less Logins Most people start using SSH by logging in with a password, but re-entering your password for every SSH connection quickly becomes tedious. A better way is to set up a public/private key pair - you unlock your key once and then reuse it to make connections without entering your password. It may sound a bit complicated but you can set it up with two simple commands* ssh-keygen ssh-copy-id hostname You run the first command once to set up your public/private key pair and then you run the second command once for each host you want to connect to. These steps are spelled out in more detail below, but those two commands are all you need to get going.

60 Excellent Free 3D Model Websites 3D models represent a 3D object using a collection of points in 3D space, connected by various geometric entities. A free 3D model definitely can save your budget and deadline. On average, a modeler saves over 2 hours of modeling time when they could get a free 3D model. Today, 3D models are used in a wide variety of industries. The movie industry uses them as characters and objects for animated and real-life motion pictures.

Adblock Everywhere: The Raspberry Pi-Hole Way Turn a cheap Raspberry Pi into a network-wide ad blocker. If you’re tired of AdBlock Plus slowing your browser down, this DNS-based option is a great alternative that works on any device. Unlike other solutions, this filters the web before it gets to your device, meaning you can block ads on your iPad or Android without the need for jailbreaking or rooting. A company called AdTrap sells a little white box that blocks ads for $129, but you shouldn’t buy it – a $35 Raspberry Pi and an SD card are all you need to make your own hardware ad blocker for every device on your network. Here’s why Pi-Hole is a better idea than browser extensions, and how to set it up.

Just when you thought you can no longer squeeze anything else into the tiny Raspberry Pi computer, think again: the puny device is getting a video camera. A report on PC World said developers expect to make the HD camera available by early spring, though the camera's specifications have yet to be finalized. "The first cameras are expected to come with a 15-centimeter (just under 6 inches) flat cable and sell for around $25. The lens on the camera is similar to those found on many camera phones and is expected to provide 5 megapixels," PC World said.

What Is Btrfs Filesystem (and Why Is It Better Than Ext4)? There is more to a hard drive than its size. While the amount of disk space is all you see marketed about a hard drive on a sales page, there is actually an extensive amount of coding that goes into making a hard drive capable of handling your applications and data in the first place. Most Linux distributions currently default to using the ext4 file system, but the future for many of them lies with the B-tree file system, better known as Btrfs.
