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!

An anonymous reader quotes a report from Wired: Hacker conferences -- like all conventions -- are notorious for giving attendees a parting gift of mystery illness. To combat "con crud," New Zealand's premier hacker conference, Kawaiicon, quietly launched a real-time, room-by-room carbon dioxide monitoring system for attendees. To get the system up and running, event organizers installed DIY CO2 monitors throughout the Michael Fowler Centre venue before conference doors opened on November 6. Attendees were able to check a public online dashboard for clean air readings for session rooms, kids' areas, the front desk, and more, all before even showing up. "It's ALMOST like we are all nerds in a risk-based industry," the organizers wrote on the convention's website. "What they did is fantastic," Jeff Moss, founder of the Defcon and Black Hat security conferences, told WIRED. "CO2 is being used as an approximation for so many things, but there are no easy, inexpensive network monitoring solutions available. Kawaiicon building something to do this is the true spirit of hacking." [...] Kawaiicon's work began one month before the conference. In early October, organizers deployed a small fleet of 13 RGB Matrix Portal Room CO2 Monitors, an ambient carbon dioxide monitor DIY project adapted from US electronics and kit company Adafruit Industries. The monitors were connected to an Internet-accessible dashboard with live readings, daily highs and lows, and data history that showed attendees in-room CO2 trends. Kawaiicon tested its CO2 monitors in collaboration with researchers from the University of Otago's public health department. The Michael Fowler Centre is a spectacular blend of Scandinavian brutalism and interior woodwork designed to enhance sound and air, including two grand pou -- carved Mori totems -- next to the main entrance that rise through to the upper foyers. Its cathedral-like acoustics posed a challenge to Kawaiicon's air-hacking crew, which they solved by placing the RGB monitors in stereo. There were two on each level of the Main Auditorium (four total), two in the Renouf session space on level 1, plus monitors in the daycare and Kuracon (kids' hacker conference) areas. To top it off, monitors were placed in the Quiet Room, at the Registration Desk, and in the Green Room. Kawaiicon's attendees could quickly check the conditions before they arrived and decide how to protect themselves accordingly. At the event, WIRED observed attendees checking CO2 levels on their phones, masking and unmasking in different conference areas, and watching a display of all room readings on a dashboard at the registration desk. In each conference session room, small wall-mounted monitors displayed stoplight colors showing immediate conditions: green for safe, orange for risky, and red to show the room had high CO2 levels, the top level for risk. Colorful custom-made Kawaiicon posters by New Zealand artist Pepper Raccoon placed throughout the Michael Fowler Centre displayed a QR code, making the CO2 dashboard a tap away, no matter where they were at the conference. Resources, parts lists, and assembly guides can be found here.

Researchers warn that rapid advances in neuroscience, pharmacology, and AI are bringing "brain weapons" out of science fiction and into real-world plausibility. They argue current arms treaties don't adequately cover these emerging tools and call for a new, proactive framework to prevent the weaponization of the human mind. The Guardian reports: Michael Crowley and Malcolm Dando, of Bradford University, are about to publish a book that they believe should be a wake-up call to the world. [...] The book, published by the Royal Society of Chemistry, explores how advances in neuroscience, pharmacology and artificial intelligence are coming together to create a new threat. "We are entering an era where the brain itself could become a battlefield," said Crowley. "The tools to manipulate the central nervous system -- to sedate, confuse or even coerce -- are becoming more precise, more accessible and more attractive to states." The book traces the fascinating, if appalling, history of state-sponsored research into central nervous system (CNS)-acting chemicals. [...] The academics argue that the ability exists to create much more "sophisticated and targeted" weapons that would once have been unimaginable. Dando said: "The same knowledge that helps us treat neurological disorders could be used to disrupt cognition, induce compliance, or even in the future turn people into unwitting agents." The threat is "real and growing" but there are gaps in international arms control treaties preventing it from being tackled effectively, they say. [...] The book makes the case for a new "holistic arms control" framework, rather than relying on existing arms control treaties. It sets out a number of practical steps that could be taken, including establishing a working group on CNS-acting and broader incapacitating agents. Other proposals concern training, monitoring and definitions. "We need to move from reactive to proactive governance," said Dando. Both men acknowledge that we are learning more about the brain and the central nervous system, which is good for humanity. They said they were not trying to stifle scientific progress and it was about preventing malign intent. Crowley said: "This is a wake-up call. We must act now to protect the integrity of science and the sanctity of the human mind."

BrianFagioli writes: President Trump has issued a sweeping executive order that creates the Genesis Mission, a national AI program he compares to a Manhattan Project level effort. It centralizes DOE supercomputers, national lab resources, massive scientific datasets, and new AI foundation models into a single platform meant to fast track research in areas like fusion, biotech, microelectronics, and advanced manufacturing. The order positions AI as both a scientific accelerator and a national security requirement, with heavy emphasis on data access, secure cloud environments, classification controls, and export restrictions. The mission also sets strict timelines for identifying key national science challenges, integrating interagency datasets, enabling AI run experimentation, and creating public private research partnerships. Whether this becomes an effective scientific engine or another oversized federal program remains to be seen, but the administration is clearly pushing to frame Trump as the president who put AI at the center of U.S. research strategy.

Sam Altman and Jony Ive say they've settled on a prototype for OpenAI's first hardware device that could ship in "less than" two years. The Verge reports: In an interview with Laurene Powell Jobs at Emerson Collective's 2025 Demo Day, they said they are currently prototyping the device, and when asked about a timeframe, Ive said it could arrive in "less than" two years. Little has been revealed so far about the OpenAI device in development, but it's rumored to be screen-free and "roughly the size of a smartphone." Altman described the design as "simple and beautiful and playful," adding that, "There was an earlier prototype that we were quite excited about, but I did not have any feeling of, "I want to pick up that thing and take a bite out of it,' and then finally we got there all of a sudden." Ive similarly emphasized simplicity and whimsy, saying, "I love solutions that teeter on appearing almost naive in their simplicity, and I also love incredibly intelligent, sophisticated products that you want to touch, and you feel no intimidation, and you want to use almost carelessly, that you use them almost without thought, that they're just tools." Altman went on to comment, "I hope that when people see it, they say, 'That's it!,'" to which Ive responded, "Yeah, they will."
