Fedup right now is the command for handling in-place Fedora upgrades from release-to-release and it's been around since Fedora 17. However, with the Fedora 23 release due out in late 2015, that utility will likely be replaced with a new version to handle upgrading to new releases.
Security researchers have published proof-of-concept code for a major router vulnerability leveraging a popular Linux kernel driver that could be used by hackers to compromise millions of connected devices.
Last year was news about Russia wanting to design its own processors to be less reliant upon Intel and AMD. The initial "Baikal" processor was expected to be based on ARMv8 but it turns out now that it's a MIPS design.

Midnight Commander (MC) is a text-based Command Line Interface (CLI) program. It is particularly useful when a GUI is not available but can also be used as a primary file manager in a terminal session even when you are using a GUI. I use Midnight Commander frequently because I often have need to interact with local and remote Linux computers using the CLI. It can be used with almost any of the common shells and remote terminals through SSH.

System administrators are aware as how important their systems security is, not just the runtime of their servers. Intruders, spammers, DDOS attack, crackers, are all out there trying to get into people’s computers, servers and everywhere they can lay hands on and interrupt the normal runtime of services. Being able to identify tools and techniques to harden your systems is a key play on securing your systems. Moreover, choosing the right tools is a matter of experience. You should try most of them, or perhaps the ones that are popular. I chose free and open source software because, if I want to, I can check the applications source code and see for myself how did programmers wrote the software, how did they manage to keep the software easy to understand etc.
Though Linux is often seen as being immune to malware it's still important to have protection, partly because Linux malware does exist, even if it’s rare, and partly to prevent the passing on of viruses to more vulnerable operating systems like Windows and Android.
This past week I've been reading up on a variety of B-tree algorithms. These have been around since the early 1970s and are extremely common in all sorts of software, so one might expect that after 40+ years of continuous use of such a simple concept that there'd be very little to talk about, but it's quite a vast territory. In fact, each year for the last two decades Donald Knuth has held a public lecture around Christmas-time about trees. (Yes, they are Christmas Tree Lectures. ;) Some of the papers I've been reading were published in just the last few years, with quite a bit of interesting research having gone on in this area over the last decade.
