Securi-Pi: Uses Raspberry Pi as a stepping stone for securityGuideLike many readers of LinuxJournal, I have also lived a very common "technology nomadic" life today, from one access point to another between networks, we are in different places in the real world, but we are always connected to the Internet and other networks that are commonly used.

GuideLike many linuxjournal readers, I have also lived in today's very popular "tech nomads" life, between networks, from one access point to another, where we are in different parts of the real world and remain connected to the Internet and other networks we use on a daily basis. Recently I have found that more and more network environments are starting to block common ports such as SMTP (port), SSH (Port 22), and so on. When you walk into a café and want to SSH into one of your servers to do s
tutorial for driving relays is most helpful to me, the bus extender controls multiple solid state relays, which directly control the switch of the heating element through the brewing software.I first put all the parts into this circuit box because it would be a rolling trolley, I would make it easy to move, not fixed, if I had a store (like in a garage, a tool room, or a basement), I needed a bigger circuit box on the wall, And now I've found a waterproof engineering box of the right size that

Use Raspberry Pi to send push notifications to smartphones
This project explains how to send push notifications from Raspberry Pi to iOS and Android devices. You only need to use a free push app. The main idea here is to use an electromagnetic sensor door to trigger information push events. When the electromagnetic doo
prove that Snappy is a system for cloud computing, especially for Iot.
Snappy can also run on other clouds such as Amazon EC2, Microsoft Azure, and Google's Compute Engine. It can also be virtualized on KVM, Virtuabox, and vagrant. Canonical Ubuntu has embraced heavyweight players such as Microsoft, Google, Docker, and OpenStack, and has reached partnerships with small projects. In addition to some startups, such as Ninja Sphere and Erle Robotics, there are also some development
