Get CPU temperature on Linux
The ability to get the temperature of a key component such as a CPU is important, whether you are gaming, overclocking, or hosting intensive processes on a critical server for your company. The Linux kernel comes with modules built in that allow it to access onboard sensors within the CPU. In this tutorial, you will learn how to access these sensors and get the CPU temperature on a Linux system.
There is a program that will work in conjunction with the kernel modules mentioned above to display the readings of the CPU temperature in the userspace. The program is called lm_sensors. This software allows users to get a readout of the CPU temperature in the command line and interfaces with several graphical front ends that make displaying temperatures in real time automatic and easy.

The lost+found Directory in Linux and UNIX
The Linux fsck system utility is directly associated with the lost+found directory construct. Executing the fsck system utility will initiate a filesystem check and repair routine.
The result of using the fsck system utility might lead to the retrieval of data fragments, not ‘registered/referenced’ by the Linux filesystem.
For instance, fsck tends to highlight data that resembles a complete file but missing a name record on the Linux system. Therefore, such nameless data tend to use up system memory and remain mysterious since there are no conventional means of accessing it.
This article is here to unravel the mysteries behind the lost+found directory and its association with the Linux fsck utility.

Hibernation in Fedora Workstation - Fedora Magazine
Hibernation stores the current runtime state of your machine – effectively the contents of your RAM, onto disk and does a clean shutdown. Upon next boot this state is restored from disk to memory such that everything, including open programs, is how you left it.
Fedora Workstation uses ZRAM. This is a sophisticated approach to swap using compression inside a portion of your RAM to avoid the slower on-disk swap files. Unfortunately this means you don’t have persistent space to move your RAM upon hibernation when powering off your machine.

Create beautiful PDFs in LaTeX | Opensource.com
The LaTeX document preparation system has an interesting history. When programmer Don Knuth wrote his first book, The Art of Computer Programming, in 1968, it was produced using an old-style printing press method. When he published the second edition in 1976, the publisher had moved to modern phototypesetting.
Knuth was unhappy with how the new edition looked. Addressing the problem from a programmer's perspective, Knuth decided to create his own text processing system so his future books could be formatted to look the same way, for every book in the series. And so it was that Don Knuth wrote the first version of TeX in 1978.
A few years later, Leslie Lamport created a set of macros that help authors write complex documents more easily. Lamport's macro extensions, LaTeX, essentially extends TeX to easily produce all kinds of documents. For example, many academic organizations use LaTeX to publish journals and proceedings.
