If you are writing a Bash shell script, you should read command-line arguments into an array for some time. This allows us to process any number of arguments provided when the script is run. This makes the script adaptable to different use cases. Instead of dealing with fixed variables like $1, $2, $3, etc., you can work with any number of arguments more dynamically using bash for loop or bash while loop, depending upon your needs. Arrays make it simple to loop through each argument and perform operations on them, whether basic printing or complex processing. Bash provides a mapfile (readarray command) internal built-in command to read lines from a file into an array variable. Let us see how to use mapfile to read all command line arguments into an array.

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!

Federal prosecutors have revealed that Peter Williams, the former general manager of U.S. defense contractor L3Harris's hacking tools division Trenchant, sold eight stolen software exploits to a Russian broker whose customers -- including the Russian government -- could have used them to access "millions of computers and devices around the world." Williams, a 39-year-old Australian national, pleaded guilty in October and admitted to earning more than $1.3 million in cryptocurrency from the sales between 2022 and 2025. In a sentencing memorandum filed Tuesday ahead of his anticipated February 24 sentencing in a Washington, D.C., federal court, the Justice Department asked the judge for nine years in prison, $35 million in restitution, and a maximum fine of $250,000. Prosecutors described the unnamed Russian buyer -- believed to be Operation Zero, which publicly claims to sell only to the Russian government -- as "one of the world's most nefarious exploit brokers." Williams chose it because, by his own admission, "he knew they paid the most." He also oversaw the wrongful firing of a subordinate who was blamed for the theft.

Linus Torvalds rejects Linux 7.0 MMC changes as 'complete garbage'  GIGAZINE

Apple's long-promised overhaul of Siri has hit fresh problems during internal testing, forcing the company to push several key features out of the iOS 26.4 update that was slated for March and spread them across later releases, Bloomberg is reporting. The new Siri -- first announced at WWDC in June 2024 and originally due by early 2025 -- struggles to reliably process queries, takes too long to respond and sometimes falls back on OpenAI's ChatGPT instead of Apple's own technology, the report said. Apple has instructed engineers to begin testing new Siri capabilities on iOS 26.5 instead, due in May, and internal builds of that update include a settings toggle labeled "preview" for the personal data features. A more ambitious chatbot-style Siri code-named Campo, powered by Google servers and a custom Gemini model, is in development for iOS 27 in September.

An anonymous reader shares a report: An Anthropic safety researcher quit, saying the "world is in peril" in part over AI advances. Mrinank Sharma said the safety team "constantly [faces] pressures to set aside what matters most," citing concerns about bioterrorism and other risks. Anthropic was founded with the explicit goal of creating safe AI; its CEO Dario Amodei said at Davos that AI progress is going too fast and called for regulation to force industry leaders to slow down. Other AI safety researchers have left leading firms, citing concerns about catastrophic risks.

Ring's Super Bowl ad on Sunday promoted "Search Party," a feature that lets a user post a photo of a missing dog in the Ring app and triggers outdoor Ring cameras across the neighborhood to use AI to scan for a match. 404 Media argues the cheerful premise obscures what the Amazon-owned company has become: a massive, consumer-deployed surveillance network. Ring founder Jamie Siminoff, who left in 2023 and returned last year, has since moved to re-establish police partnerships and push more AI into Ring cameras. The company has also partnered with Flock, a surveillance firm used by thousands of police departments, and launched a beta feature called "Familiar Faces" that identifies known people at your door. Chris Gilliard, author of the upcoming book Luxury Surveillance, called the ad "a clumsy attempt by Ring to put a cuddly face on a rather dystopian reality: widespread networked surveillance by a company that has cozy relationships with law enforcement."
