In prior installments, we saw that systemd services can be started or stopped by hand or when certain conditions are met. Those conditions are not limited to when the OS reaches a certain state in the boot up or powerdown sequence but can also be when you plug in new hardware or when things change in the filesystem. You do that by combining a Udev rule with a systemd service.

Andiry Xu posted patches for a new filesystem called NOVA (NOn-Volatile memory Accelerated). Normal RAM chips are wiped every time you turn off your computer. Non-volatile RAM retains its data across reboots. Their project targeted byte-addressable non-volatile memory chips, such as Intel's 3DXpoint DIMMs.

If you search the internet for "unexpected API behavior," you'll soon discover that no one likes when an API doesn't work as anticipated. When you consider the increasing number of APIs, continuous development, and delivery of the services built on top of them, it's no surprise that APIs can diverge from their expected behavior. This is why API test coverage is critical for success. For years, we have created unit and functional tests for our APIs, but where do we go from there? read more

Open source has won. The fact that free software now dominates practically every sector of computing (with the main exception of the desktop) is proof of that... Open, collaborative development allows people to build on the work of others, instead of wastefully re-inventing the wheel, and it enables the best solutions to be chosen on technical, rather than commercial, grounds.

Creating and deleting partitions in Linux is a regular practice because storage devices (such as hard drives and USB drives) must be structured in some way before they can be used. In most cases, large storage devices are divided into separate sections called partitions. Partitioning also allows you to divide your hard drive into isolated sections, where each section behaves as its own hard drive. Partitioning is particularly useful if you run multiple operating systems. read more
