Raspberry Pi-rsync and Raspberry Pi rsyncYou can use rsync to synchronize folders between different computers. You may want to transfer a file from your desktop computer or laptop to your Raspberry Pi and keep the file updated. Or
In my previous article, I talked about how to build a high-availability system: Two Raspberry Pi deploy the GlusterFS cluster file system, and it becomes a fault-tolerant file server. In this article, we will build another Fault-Tolerant Service Based on this high-availability system: Build a simple Web server cluster.

next step is to use some time to generate the Diffie-hellman key required by the OpenVPN server. This step will take a few minutes on a typical desktop-level CPU, but on an ARM-architected Raspberry Pi, it will be a super-long time. Be patient, as long as the points on the terminal are still jumping, then everything is running in step-by-step (The following example omits a few points):[Email protected]:/et
continue to run the START process.
In addition, make sure that the file name uses an absolute path instead of a relative path relative to your home directory. For example/Home/pi/myscript. pyInstead of usingMyscript. py.

Select a title for your time. We recommend that you do not add any spaces to the event name. I am using "DoorAlert"
You need to add at least one tracker. This is basically a variable used in push notifications. I name it "message"
Finally, enter the message content you want to push. My Python code sends the variable {message} to the Instapush service. Therefore, I suggest you only add {message} to the Message field. Click Add event

The Internet of Things (IoT) era is approaching. Soon, in a few years, we will ask ourselves how we were able to survive without the Internet of Things, just as we now suspect that there was no mobile phone in the past. Canonical is a fast-growing but open-market competitor of Iot. The company claims to place its bet on IoT, just as they have done on the cloud
