Excerpt from Wikipedia: Pi-hole is a Linux network-level advertisement and Internet tracker blocking application which acts as a DNS sinkhole and optionally a DHCP server, intended for use on a private network. It is designed for use on embedded devices with network capability, such as the Raspberry Pi, but it can be used on other machines running Linux, including cloud implementations.
Excerpt: The Linux vanilla kernel repositories for Fedora offer RPM packages containing vanilla builds of different Linux kernel version lines. These packages are meant for Fedora users that want to access the latest Linux kernels quickly and comfortably; either the latest mainline kernel, the latest stable kernel or a vanilla variant of the Linux kernel version line Fedora uses currently.
Excerpt from man: Snapper is a command-line program for filesystem snapshot management. It can create, delete and compare snapshots and undo changes done between snapshots.
Snapper never modifies the content of snapshots. Thus snapper creates read-only snapshots if supported by the kernel. Supported filesystems are btrfs as well as snapshots of LVM logical volumes with thin-provisioning.

From Wikipedia: Origami (折り紙, Japanese pronunciation: [oɾiɡami] or [oɾiꜜɡami], from ori meaning “folding”, and kami meaning “paper” (kami changes to gami due to rendaku)) is the art of paper folding, which is often associated with Japanese culture. In modern usage, the word “origami” is used as an inclusive term for all folding practices, regardless of their culture of origin.
Excerpt from man intel, option “TearFree”: Disable or enable TearFree updates. This option forces X to perform all rendering to a backbuffer prior to updating the actual display. It requires an extra memory allocation the same size as a framebuffer, the occasional extra copy, and requires Damage tracking. Thus enabling TearFree requires more memory and is slower (reduced throughput) and introduces a small amount of output latency, but it should not impact input latency.
This is a copy from the ZXing repo wiki pages at commit hash 3110236. ZXing is an open-source, multi-format 1D/2D barcode image processing library implemented in Java, with ports to other languages.
Much has been said about 2D barcodes, and the discussion has focused on the format of the 2D barcode itself – QR Code, Data Matrix, and so on.
