Collaborate on a file using Linux diff and patch
I edit a lot of text files. Sometimes it's code. Other times it's the written word for role-playing games (RPGs), programming books, or general correspondence. Sometimes it's nice to make a change, but for my collaborator to compare my change with what they originally had written. Many people default to office suites, like LibreOffice, using comments or change tracking features. Sometimes a simpler tool makes more sense, though, and for that, you can look at programming history for tools like diff and patch, which provide standardized formatting for tracking and applying changes to shared files.

Quickemu- Run Windows 11 on Ubuntu 20.04 LTS Linux in few clicks
o you want to install Windows 10 or 11 on your Ubuntu 20.04 or 22.04 LTS Linux using QEMU-KVM virtual machine? Then here is a tutorial to do that using the command terminal and Quickemu + Quickgui.
Although we all have a simple solution that is a virtual box to run Windows 11 virtual machine, what about KVM? Some will say it is not easy to operate because of the command line but no there are few open-source GUI programs to give KVM an easy interface. However, another thing is downloading ISO images of various operating systems including Windows 10 or 11 to use with Virtualbox can be a headache. Hence, to solve all of this, there is a project called QuickEMU with a GUI interface known as QuickGUI. QickEMU uses QEMU_KVM on Linux operating system to run a virtual machine and can easily download all popular operating system Images to install including macOS. Whereas it can be operated via CLI but for ease of usage users can install QuickGUI to download, create, and manage operating systems virtual machines.

Steinar H. Gunderson: Commitcoin
How do you get a git commit with an interesting commit ID (or “SHA”)? Of course, interesting is in the eye of the beholder, but let's define it as having many repeated hex nibbles, e.g. “000” in the commit would be somewhat interesting and “8888888888888888888888888” would be very interesting. This is pretty similar to the dreaded cryptocoin mining; we have no simple way of forcing a given SHA-1 hash unless someone manages a complete second-preimage break, so we must brute-force. (And hopefully without boiling the planet in the process; we'd have to settle for a bit shorter runs than in the example above.)
Git commit IDs are SHA-1 checksums of what they contain; the tree object (“what does the commit contain”), the parents, the commit message and some dates. Of those, let's use the author date as the nonce (I chose to keep the committer date truthful, so as to not be accused of forging history too much). We can set up a shell script to commit with --amend, sweeping GIT_AUTHOR_DATE over the course of a day or so and having EDITOR=true in order not to have to close the editor all the time.

How to check if packages in RHEL-based Linux distributions have been patched for specific CVEs - TechRepublic
CVEs (Common Vulnerabilities and Exposures) are constantly being discovered and patched. When discovered, it means a new security flaw exists in either an operating system or a piece of software and should be patched as soon as possible. Fixing the vulnerabilities, of course, is up to the developers. Patching those vulnerabilities, however, is up to the admin (or user). Thing is, you might not know if you're using a piece of software that includes one or more CVEs.
How do you uncover this information? Do you have to spend hours researching? Not really. In fact, all you need to know is the CVE you're looking for and the piece of software it affects. With those two bits of information in hand, you can quickly discover if what's installed on your Red Hat Enterprise Linux-based distribution contains that vulnerability.
I'm going to show you how to do just that.
