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!

Finnish authorities on Wednesday seized a vessel suspected of severing an undersea telecommunications cable that connects Helsinki to Tallinn by dragging its anchor across the Gulf of Finland, the latest in a string of infrastructure incidents that have put Baltic Sea nations on edge since Russia's 2022 invasion of Ukraine. Police are investigating the case as aggravated criminal damage and have not disclosed the ship's name, nationality or details about its crew. The cable belongs to Finnish telecoms group Elisa. Estonia's justice ministry reported that a second telecoms cable connecting the two countries -- owned by Sweden's Arelion -- also went down on Wednesday. This follows Finland's December 2024 boarding of the Russian-linked oil tanker Eagle S, which investigators said damaged a power cable and multiple telecoms links using the same anchor-dragging method. A Finnish court in October dismissed criminal charges against the Eagle S crew after prosecutors failed to prove intent.

China's Commerce Ministry on Wednesday demanded that the Netherlands "immediately correct its mistakes" over chipmaker Nexperia, escalating a standoff that has disrupted global semiconductor supply chains and triggered warnings from automakers about component shortages. The Dutch government in September invoked a Cold War-era law to effectively seize control of the Chinese-owned chipmaker, reportedly after the United States raised security concerns. China responded by blocking Nexperia products from leaving the country. Nexperia manufactures billions of foundation chips -- transistors, diodes and power management components -- that are produced in Europe, assembled and tested in China, and then re-exported to customers worldwide. These low-tech, inexpensive chips are essential in almost every device that uses electricity, from car braking systems and airbag controllers to electric windows and entertainment systems. The Commerce Ministry spokesperson said the Netherlands "remains indifferent and stubbornly insists on its own way, showing absolutely no responsible attitude towards the security of the global semiconductor supply chain." Dutch Economy Minister Vincent Karremans has repeatedly defended the intervention. Auto industry groups have warned that disruptions have not been fundamentally resolved. Japan's Nissan and German supplier Bosch have flagged looming shortages, and the German Association of the Automotive Industry warned of elevated supply risks "particularly for the first quarter" of 2026.

This fully atomic Linux distro is a challenge to install but a treat to use  ZDNET

Longtime Slashdot reader ptorrone writes: The January 1, 2026, NYC mayoral inauguration prohibits attendees from bringing specific brand-name devices, explicitly banning Raspberry Pi single-board computers and the Flipper Zero, listed alongside weapons, explosives, and drones. Rather than restricting behaviors or capabilities like signal interference or unauthorized transmitters, the policy names two widely used educational and testing tools while allowing smartphones and laptops that are far more capable. Critics argue this device-specific ban creates confusion, encourages selective enforcement, and reflects security theater rather than a clear, capability-based public safety framework. New York has handled large-scale events more pragmatically before.
