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.

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!

"Since the United States reopened its embassy in Cuba in 2015, a number of personnel have reported a series of debilitating medical ailments which include dizziness, fatigue, problems with memory, and impaired vision," writes longtime Slashdot reader smooth wombat. "For ten years, these sudden and unexplained onsets have been studied with no conclusive evidence one way or the other. Now comes word that a device, purchased by the Pentagon, has been tested which may be linked to what is known as Havana Syndrome." From a report: A division of the Department of Homeland Security, Homeland Security Investigations, purchased the device for millions of dollars in the waning days of the Biden administration, using funding provided by the Defense Department, according to two of the sources. Officials paid âoeeight figuresâ for the device, these people said, declining to offer a more specific number. [...] The device acquired by HSI produces pulsed radio waves, one of the sources said, which some officials and academics have speculated for years could be the cause of the incidents. Although the device is not entirely Russian in origin, it contains Russian components, this person added. Officials have long struggled to understand how a device powerful enough to cause the kind of damage some victims have reported could be made portable; that remains a core question, according to one of the sources briefed on the device. The device could fit in a backpack, this person said. [...] One key concern now for some officials is that if the technology proves viable it may have proliferated, several of the sources said, meaning that more than one country could now have access to a device that may be capable of causing career-ending injuries to US officials.

Meta is shutting down three acquired VR studios as part of Reality Labs layoffs and a strategic pivot away from VR content toward AI-powered smart glasses. UploadVR reports: Meta shut down Twisted Pixel Games (Deadpool VR), Sanzaru Games (Asgard's Wrath), and Armature Studio (Resident Evil 4 VR). [...] Twisted Pixel Games was founded in 2006 and mostly made Xbox games published by Microsoft for the first decade of its existence. In fact, Microsoft owned the studio from 2011 until 2015, when it became an independent company again. On contract from Facebook, between 2017 and 2019 Twisted Pixel released four VR games: Wilson's Hearth (Rift); B-Team (Go/Quest); Defector (Rift); and Path of the Warrior (Rift/Quest). In 2022, Twisted Pixel Games was acquired by Meta. And just two months ago, it released what it had been working on since then: Deadpool VR, the latest Quest-exclusive VR game. [...] Sanzaru Games was also founded in 2006, and made a combination of its own games and contract titles for companies such as Sony, porting the original God of War series to PS Vita. Sanzaru Games was also contracted by Facebook to build VR games for the Oculus Rift and its Touch controllers, between 2016 and 2019: Ripcoil (2016); VR Sports Challenge (2016); Marvel Powers United VR (2018); and Asgard's Wrath (2019). In 2020, Sanzaru Games was acquired by Facebook, and in 2023 released Asgard's Wrath 2, taking the core essence of Asgard's Wrath to Quest 2 and Quest 3 standalone, with a semi-open world and a campaign more than 60 hours long. Exactly one year ago, Sanzaru released the last major content update for Asgard's Wrath 2, stating that it was now working on the "next big thing" with no detail released on what that would be before the studio closed. Founded in 2008, Armature Studio was mainly a porting studio, bringing PC titles to consoles and console titles to PS Vita. Like Twisted Pixel and Sanzaru, Armature too was contracted by Facebook to build early consumer VR games: Fail Factory (2017); Sports Scramble (2019); and Resident Evil 4 VR (2021). Armature was acquired by Meta in 2022, and many VR gamers had been eagerly anticipating what it had been working on since. Whatever it was, Armature too is now shut down.

The U.S. Senate unanimously passed the Disrupt Explicit Forged Images and Non-Consensual Edits Act (DEFIANCE Act), giving victims of sexually explicit AI deepfakes the right to sue the individuals who created them. The Verge reports: The bill passed with unanimous consent -- meaning there was no roll-call vote, and no Senator objected to its passage on the floor Tuesday. It's meant to build on the work of the Take It Down Act, a law that criminalizes the distribution of nonconsensual intimate images (NCII) and requires social media platforms to promptly remove them. [...] Now the ball is again in the House leadership's court; if they decide to bring the bill to the floor, it will have to pass in order to reach the president's desk.

An anonymous reader quotes a report from Network World: The global technology sector eliminated some 244,851 jobs in 2025, according to a report from RationalFX. The U.K.-based financial services company says the worldwide downsizing reflects how companies in 2025 restructured their operations to focus on efficiency, profitability, and AI-driven productivity. The RationalFX analysis, which examined layoffs reported by TrueUp, TechCrunch, and multiple state WARN databases, points to economic uncertainty, elevated interest rates, and accelerating AI and automation adoption as reasons that 2025 marked "another year of sustained downsizing following the post-pandemic correction that began in 2022." Companies indicated that AI and automation were among the most frequently cited drivers for layoffs in 2025. Some companies retrained employees when faced with the technology; many replaced roles entirely, RationalFX reports. "Tech sector layoffs in 2025 displaced hundreds of thousands of workers worldwide as companies accelerated structural resets rather than short-term cost corrections," said Alan Cohen, analyst at RationalFX, in a statement. "While macroeconomic pressures such as high interest rates, trade restrictions, and geopolitical uncertainty continued to weigh on business confidence, the dominant force behind last year's job cuts was the rapid adoption of automation and artificial intelligence." The analysis also uncovered that U.S.-headquartered technology companies were responsible for the majority of job losses, accounting for approximately 69.7% of all global tech layoffs. This resulted in more than 170,000 employees being cut across both domestic and offshore operations from U.S. tech companies. California spearheaded layoffs in the U.S. tech sector this year, with 73,499 job cuts accounting for roughly 43.08% of all tech layoffs in the country, according to the RationalFX report. The report also points out that Washington has seen 42,221 tech jobs cut since the start of the year, accounting for 24.74% of all U.S. tech layoffs. Intel contributed the single largest number of layoffs last year, reducing its headcount from 109,000 people at the end of 2024 to around 75,000 by the end of 2025. Other major U.S. tech companies with large-scale layoffs last year include Amazon (more than 20,000 jobs cut), Microsoft (approximately 19,215 layoffs), Verizon (15,000 employees), Accenture (11,000 employees), IBM (9,000 job cuts), and HP (6,000 roles).

BrianFagioli writes: Wine 11.0 has officially landed, wrapping up a year of development with more than 6,000 code changes and a broad set of upgrades that touch gaming, desktop behavior, and long-standing architectural work. The biggest milestone is the completion of the new WoW64 model, which is now considered fully supported and allows 32-bit and even 16-bit applications to run in a cleaner way inside 64-bit prefixes. Wine also gains support for the NTSYNC kernel module now bundled in Linux 6.14, which cuts overhead from thread synchronization and should deliver observable performance benefits in games and multi-threaded applications. A single unified wine binary now replaces the old wine64 launcher, and several system behaviors align more closely with modern Windows, including syscall numbering and NT reparse points. Graphics and desktop integration received more polish, including deeper Vulkan support (up to API 1.4.335), hardware-accelerated H.264 decoding through Direct3D, and further improvements to Wine's Wayland driver, which now supports clipboard operations, IMEs, and shaped windows. X11 users gain better window activation and fullscreen handling, and legacy DirectX features continue to expand under Wine's Vulkan renderer. Device support also moves forward, with better joystick handling, improved Bluetooth visibility and pairing, and working TWAIN scanning on 64-bit apps. Broad multimedia updates, DirectMusic refinements, .NET/XNA improvements, and developer-facing tools round out a release that appears focused on smoothing sharp edges rather than introducing flashy experiments. As always, source is live now and distro packages are rolling out.
