Strange as it may seem to older generations of computer users who grew up maintaining an elaborate collection of nested subfolders, thanks to powerful search functions now being the default in operating systems, as well as the way phones and tablets obfuscate their file structure, and cloud storage, high school graduates don’t see their hard drives the same way.
So how do you convert such input? The answer is to use jq or dasel command-line utilities.
If you are currently using CentOS 8, you will have to find an alternative operating system. This is because its end-of-life cycle has been cut short in December 2021. But if you use CentOS 7, you do not have to take any action right now. This is because CentOS 7 will reach its End-of-Life on June 30th, 2024.
Stupid me installed CentOS 8 in December 2020 instead of 7 without reading the news about this.
While it is somewhat understandable that Red Hat may not want to support a free enterprise-grade Linux OS forever, there was a real sting in Red Hat’s announcement last year, as it leaves CentOS 8 users in a tough spot, needing to secure their CentOS 8 workloads rapidly.
The end of CentOS 8 Linux has been coming for awhile now, and the day is finally here. On December 31, 2021, Red Hat‘s CentOS Linux 8 will reach End Of Life (EOL). Since that falls right in the heart of the holiday season, Red Hat will extend CentOS Linux 8 zero-day support until January 31, 2022. Indeed, there will be one last CentOS Linux 8 release — perhaps even after CentOS 8’s official EOL. After that, it’s all over for CentOS Linux.
Yikes! Just heard about this. Last year I chose CentOS 8 over 7 for this server so I would not have to deal with end of life issues for awhile. It appears CentOS 7 will be good until 2024 and 8 ends today. Ugh.

You can run Pi-hole in a container, or deploy it directly to a supported operating system via our automated installer.
What’s more interesting is that this flaw can be exploited by an attacker to run commands as root just by specifying the user ID “-1” or “4294967295.”
That’s because the function which converts user id into its username incorrectly treats -1, or its unsigned equivalent 4294967295, as 0, which is always the user ID of root user..
Dennis MacAlistair Ritchie’s was “dmac”, Bourne’s was “bourne”, Schmidt’s was “wendy!!!” (his wife’s name), Feldman’s was “axlotl”, and Kernighan’s was “/.,/.,”.
and Ken Thompson’s was “p/q2-q4!” (chess notation for a common opening move).
CentOS offers a bit of a different take on installing and updating packages. First off, the default package manager has migrated from YUM to DNF. The command structure for each is quite similar, so instead of running a command like:sudo yum install httpd
You’d issue the command:sudo dnf install httpd
For more information on DNF, see How to use the DNF package manager.
