When hacking with a Raspberry Pi Zero (or similar device), many makers use the General Purpose Input / Output (GPIO) pins. These pins are used to attach and control a wide range of devices such as LEDs or sensors to measure temperature, light, or humidity.

At Red Hat we like to say, "Containers are Linux—Linux is Containers." Here is what this means. Traditional containers are processes on a system that usually have the following three characteristics: 1. Resource constraints When you run lots of containers on a system, you do not want to have any container monopolize the operating system, so we use resource constraints to control things like CPU, memory, network bandwidth, etc. The Linux kernel provides the cgroups feature, which can be configured to control the container process resources.

DomTerm is a modern terminal emulator that uses a browser engine as a "GUI toolkit." This enables some neat features, such as embeddable graphics and links, HTML rich text, and foldable (show/hide) commands.
