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.

When one company asked job applicants to submit a video where they answer a question, most of the 300 responses were "eerily similar," reports the Washington Post (with a company executive saying it was "abundantly clear" they'd used AI.) Job seekers are turning to AI to help them land jobs more quickly in a tough labor market.... Employers say that's having an unintended consequence: Many applications are looking and sounding the same... It's easy to spot when candidates over-rely on AI, some employers said. Oftentimes, executive summaries will look eerily similar to each other, odd phrases that people wouldn't normally use in conversation creep into descriptions, fancy vocabulary appears, and someone with entry-level experience uses language that indicates they are much more senior, they added. It's worse when they use auto-apply AI tools, which will find jobs, fill out applications and submit résumés on the candidate's behalf, some employers said. Those tend to misinterpret some of the application questions and fill in the wrong information in inappropriate spots. If these applications were evaluated alone, employers say they'd have a harder time identifying AI usage. But when hundreds of applications all have the same issue, they said, AI's role in it becomes obvious. The article acknowledges that some employers could be using AI tools to screen resumes too. One job-seeker in Texas even says he'll stop submitting an AI-written résumé when the recruiter stops using AI to evaluate them. "You're saying, 'You shouldn't be doing this' when I know a good chunk of them do this!" Obligatory XKCD.

This week Raspberry Pi saw its stock price surge more than 60% above its early-February low (before giving up some gains at the end of the week). Reuters notes the rise started when CEO Eben Upton bought 13,224 pounds worth of shares — but there could be another reason. "The rally in the roughly $800 million company has materialised alongside social-media buzz that demand for its single-board computers could pick up as people buy them to run AI agents such as OpenClaw." The Register explains: The catalyst appears to have been the sudden realization by one X user, "aleabitoreddit," that the agentic AI hand grenade known as OpenClaw could drive demand for Raspberry Pis the way it had for Apple Mac Minis. The viral AI personal assistant, formerly known as Clawdbot and Moltbot, has dominated the feeds of AI boosters over the past few weeks for its ability to perform everyday tasks like sending emails, managing calendars, booking appointments, and complaining about their meatbag masters on the purportedly all-agent forum known as MoltBook... In case it needs to be said, no one should be running this thing on their personal devices lest the agent accidentally leak your most personal and sensitive secrets to the web... In this context, a cheap low-power device like a Raspberry Pi makes a certain kind of sense as a safer, saner way to poke the robo-lobster... The Register argues Raspberry Pis aren't as cheap as they used to be "thanks in part to the global memory crunch. Today, a top-specced Raspberry Pi 5 with 16GB of memory will set you back more than $200, up from $120 a year ago." "You know what's cheaper, easier, and more secure than letting OpenClaw loose on your local area network? A virtual private cloud..."

Linus Torvalds jokingly ponders his successor as Linux boss  theregister.com

Russia's domestic intelligence agency claimed Saturday that Ukraine can obtain sensitive information from troops using the Telegram app on the front line, reports Bloomberg. The fact that the claims were made through Russia's state-operated news outlet RIA Novosti signals "tightening scrutiny over a platform used by millions of Russians," Bloomberg notes, as the Kremlin continues efforts to "push people to use a new state-backed alternative." Russia's communications watchdog limited access to Telegram — a popular messaging app owned by Russian-born billionaire Pavel Durov — over a week ago for failing to comply with Russian laws requiring personal data to be stored locally. Voice and video calls were blocked via Telegram in August. The pressure is the latest move in a long-running campaign to promote what the Kremlin calls a sovereign internet that's led to blocks on YouTube, Instagram and WhatsApp... Foreign intelligence services are able to see Russia's military messages in Telegram too, Russia's Minister for digital development, Maksut Shadaev, said on Wednesday, although he added that Russia will not block access to Telegram for troops for now. Telegram responded at the time that no breaches of the app's encryption have ever been found. "The Russian government's allegation that our encryption has been compromised is a deliberate fabrication intended to justify outlawing Telegram and forcing citizens onto a state-controlled messaging platform engineered for mass surveillance and censorship," it said in an emailed response.

Fossil fuels produce NO2, which is linked to asthma attacks, bronchitis, and higher risks of heart disease and stroke, according the EV news site Electrek. But the nonprofit news site Grist.org notes a new analysis showing that those emissions decreased by 1.1% for every increase of 200 electric vehicles — across nearly 1,700 ZIP codes. "A pretty small addition of cars at the ZIP code level led to a decline in air pollution," said Sandrah Eckel, a public health professor at the University of Southern California's Keck School of Medicine and lead author of the study. "It's remarkable." The study was done at the University of Southern California's medical school, by researchers using high-resolution satellite data, reports Electrek: The study, just published in The Lancet Planetary Health and partly funded by the National Institutes of Health, adds rare real-world evidence to a claim that's often taken for granted — that EVs don't just cut carbon over time, they also improve local air quality right now... The researchers ran multiple checks to make sure the trend wasn't driven by unrelated factors. They accounted for pandemic-era changes by excluding 2020 in some analyses and controlling for gas prices and work-from-home patterns. They also saw the expected counterexample: neighborhoods that added more gas-powered vehicles experienced increases in pollution. The findings were then replicated using updated ground-level air monitoring data dating back to 2012... Next, the researchers plan to compare EV adoption with asthma-related emergency room visits and hospitalizations. If those trends line up, it could provide some of the clearest evidence yet of what we already know: that electrifying transportation doesn't just clean the air on paper; it improves public health in practice.
