CentOS, RHEL (Red Hat Enterprise Linux), Fedora and other clones of RHEL, such as Oracle, Alma, and Rocky, offer support for version pinning. This feature allows developers and system administrators to lock a particular package to a specific version, preventing it from being automatically updated by yum or dnf commands. Sometimes, it is necessary to protect packages from being updated to newer versions to avoid incompatibility issues with your applications. For example, you can lock down PHP version 8.3.6 and avoid using updated PHP version 8.4. Let us see how to lock a package to a specific version, only exclude a package from yum update or dnf update on a CentOS, RHEL, Fedora, and friends.

Here's a quick tip for vim users. You can perform find and replace operations within a visual selection in Vim for text or code block. Visual selection for finding and replacing text in Vim allows developers and Linux/Unix users precise and efficient text editing. It's handy when you want to change specific portions of text or code blocks within a larger file without affecting other occurrences. This method required to minimizing manual search and reducing the risk of unintended code or text modifications. Let us see how to find and replace in Vim visual mode selection.

Recently, I had a learning experience with cron jobs and acme.sh. acme.sh is an excellent tool that simplifies the management of Let's Encrypt TLS (SSL) certificates. It makes obtaining and renewing these essential security certificates for your web server easier. Recently, I moved my server from Linode to AWS, which was a new environment for me. Initially, everything appeared to be working correctly, and I assumed everything was running smoothly. However, I forgot to migrate the cron job that acme.sh uses to renew the certificate automatically. This oversight caused my Let's Encrypt certificates to expire, resulting in security warnings and potential disruptions for visitors to my website. Opps!

You can find the timezone in Linux using the command line.

The senior editor at the blog Windows Central decries two serious Windows issues "that were not spotted by Microsoft during testing, and are so severe that the company has now issued an emergency fix to address the problems." Microsoft's first update for Windows 11 in 2026 has already caused two major issues that saw users unable to fully shutdown their PCs or sign-in into a device when using Remote Desktop... Being unable to shut down your PC due to a recent OS update is a huge oversight on Microsoft's part, but this is the latest in a long list of updates over the last year to cause a major issue like this... Other issues that have cropped up in Windows 11 in the last year include a bug that caused Task Manager to fail to close when the user exited the application, causing system resources to lock up after a prolonged period of time if the user had opened and closed Task Manager multiple times in a session. Another update caused saw File Explorer flashbang users with a white screen when opening it in dark mode, which appeared in an update that was supposed to improve dark mode on Windows 11... For whatever reason, the Windows Insider Program doesn't appear to be working anymore, as severe bugs are somehow making it into shipping versions of the OS. "The out of band updates, KB5077744 and KB5077797, are available now via Windows Update and is rolling out to everybody," they write. "Once installed, your PC should go back to being able to shut down successfully, and signing-in via Remote Desktop should work again." Microsoft has also officially acknowledged a third bug which crashes Outlook Classic when using POP accounts, according to the blog Windows Latest, which adds that that bug has not yet been fixed. They've also identified other minor bugs, including "a black screen problem in Windows 11 KB5074109... either due to the update itself or some compatibility issues with GPU drivers." After you install the January 2026 Update, Windows triggers random black screens where the desktop freezes for a second or two, the display goes black, then everything comes back. I can't pinpoint any specific configuration, but I can confirm the black screen issue has been observed on a small subset of PCs with both Nvidia and AMD GPUs. After you install the January 2026 Update, Windows triggers random black screens where the desktop freezes for a second or two, the display goes black, then everything comes back.

Linux 6.19 Landing Fixes For USB2/USB3 Issues With Apple M1/M2 Macs  Phoronix

An anonymous reader shared this report from CNN: Particles from Earth's atmosphere have been carried into space by solar wind and have been landing on the moon for billions of years, mixing into the lunar soil, according to a new study [published in the journal Nature Communications Earth & Environment last month]. The research sheds new light on a puzzle that has endured for over half a century since the Apollo missions brought back lunar samples with traces of substances such as water, carbon dioxide, helium and nitrogen embedded in the regolith — the moon's dusty surface layer. Early studies theorized that the sun was the source of some of these substances. But in 2005 researchers at the University of Tokyo suggested that they could have also originated from the atmosphere of a young Earth before it developed a magnetic field about 3.7 billion years ago. The authors suspected that the magnetic field, once in place, would have stopped the stream by trapping the particles and making it difficult or impossible for them to escape into space. Now, the new research upends that assumption by suggesting that Earth's magnetic field might have helped, rather than blocked, the transfer of atmospheric particles to the moon — which continues to this day. "This means that the Earth has been supplying volatile gases like oxygen and nitrogen to the lunar soil over all this time," said Eric Blackman, coauthor of the new study and a professor in the department of physics and astronomy at the University of Rochester in New York. Earth's magnetic field "somewhat inflates the atmosphere of Earth" when it's hit by solar winds, according to study coauthor Eric Blackman, a physics/astronomy professor at New York's University of Rochester. He told CNN the moon passes through this region for a few days each month, with particles landing on the lunar surface and embedding in the soil (because the moon lacks an atmosphere that would block them). This also means the moon's soil could actually contain a chemical record of Earth's ancient atmosphere, according to the study — "spanning billions of years..."

Slashdot reader BrianFagioli writes: Acer has filed three separate patent infringement lawsuits against AT&T, Verizon, and T-Mobile, taking the unusual step of hauling the nation's largest wireless carriers into federal court. The suits, filed in the Eastern District of Texas, claim the companies are using Acer-developed cellular networking technology without paying for the privilege. Acer says it tried to negotiate licenses for years but reached a dead end, arguing it was left with no option except litigation. The case centers on six U.S. patents Acer asserts are core to modern wireless networks, rather than anything tied to PCs or laptops. The company describes itself as reluctant to pursue courtroom battles, but it has been quietly building a large global patent portfolio after pouring hundreds of millions of dollars into R&D. Acer also notes that some of its patents count as standard-essential, hinting the carriers may be required to license them. All three companies are expected to push back, and the dispute could become another long-running telecom patent saga. Consumers will not notice any immediate changes, but if Acer wins or settles, it may find a new revenue stream far beyond its traditional hardware business. Further coverage from Hot Hardware
