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!

Freelance workers using AI tools are earning significantly more than their counterparts, with AI-related freelance earnings climbing 25% year over year and AI freelancers commanding over 40% higher hourly rates than non-AI workers, according to new data from Upwork. The freelance marketplace analyzed over 130 work categories and tracked millions of job posts over six months, finding that generative AI is simultaneously replacing low-complexity, repetitive tasks while creating demand for AI-augmented work. Workers using AI for augmentation outnumber those using it for automation by more than 2 to 1. Freelancers with coding skills comprising at least 25% of their work now earn 11% more for identical jobs compared to November 2022 when ChatGPT launched.

Apple must face the U.S. Department of Justice's lawsuit accusing the iPhone maker of unlawfully dominating the U.S. smartphone market, a judge ruled on Monday. From a report: U.S. District Judge Julien Neals in Newark, New Jersey, denied Apple's motion to dismiss the lawsuit accusing the company of using restrictions on third-party app and device developers to keep users from switching to competitors and unlawfully dominate the market. The decision would allow the case to go forward in what could be a years-long fight for Apple against enforcers' attempt to lower what they say are barriers to competition with Apple's iPhone.

An anonymous reader shares a report: Sen. Ted Cruz (R-Texas) has a plan for spectrum auctions that could take frequencies away from Wi-Fi and reallocate them for the exclusive use of wireless carriers. The plan would benefit AT&T, which is based in Cruz's home state, along with Verizon and T-Mobile. Cruz's proposal revives a years-old controversy over whether the entire 6 GHz band should be devoted to Wi-Fi, which can use the large spectrum band for faster speeds than networks that rely solely on the 2.4 and 5 GHz bands. Congress is on the verge of passing legislation that would require spectrum to be auctioned off for full-power, commercially licensed use, and the question is where that spectrum will come from. When the House of Representatives passed its so-called "One Big Beautiful Bill," it excluded all of the frequencies between 5.925 and 7.125 gigahertz from the planned spectrum auctions. But Cruz's version of the budget reconciliation bill, which is moving quickly toward a final vote, removed the 6 GHz band's protection from spectrum auctions. The Cruz bill is also controversial because it would penalize states that regulate artificial intelligence. Instead of excluding the 6 GHz band from auctions, Cruz's bill would instead exclude the 7.4-8.4 GHz band used by the military. Under conditions set by the bill, it could be hard for the Commerce Department and Federal Communications Commission to fulfill the Congressional mandate without taking some spectrum away from Wi-Fi.

Apple is considering using AI technology from Anthropic or OpenAI to power a new version of Siri, according to Bloomberg, sidelining its own in-house models in a potentially blockbuster move aimed at turning around its flailing AI effort. From the report: The iPhone maker has talked with both companies about using their large language models for Siri, according to people familiar with the discussions. It has asked them to train versions of their models that could run on Apple's cloud infrastructure for testing, said the people, who asked not to be identified discussing private deliberations. If Apple ultimately moves forward, it would represent a monumental reversal. The company currently powers most of its AI features with homegrown technology that it calls Apple Foundation Models and had been planning a new version of its voice assistant that runs on that technology for 2026. A switch to Anthropic's Claude or OpenAI's ChatGPT models for Siri would be an acknowledgment that the company is struggling to compete in generative AI -- the most important new technology in decades. Apple already allows ChatGPT to answer web-based search queries in Siri, but the assistant itself is powered by Apple.

TorrentFreak spotlights VP.net, a brand-new service from Private Internet Access founder Andrew Lee (the guy who gifted Linux Journal to Slashdot) that eliminates the classic "just trust your VPN" problem by locking identity-mapping and traffic-handling inside Intel SGX enclaves. The company promises 'cryptographically verifiable privacy' by using special hardware 'safes' (Intel SGX), so even the provider can't track what its users are up to. The design goal is that no one, not even the VPN company, can link "User X" to "Website Y." Lee frames it as enabling agency over one's privacy: "Our zero trust solution does not require you to trust us - and that's how it should be. Your privacy should be up to your choice - not up to some random VPN provider in some random foreign country." The team behind VP.net includes CEO Matt Kim as well as arguably the first Bitcoin veterans Roger Ver and Mark Karpeles. Ask Slashdot: Now that there's a VPN where you don't have to "just trust the provider" - arguably the first real zero-trust VPN - are trust based VPNs obsolete?

Automattic CEO Matt Mullenweg said he regrets telling the media that "WordPress.org just belongs to me personally" during a new interview about his company's legal dispute with hosting provider WP Engine. The comment has been "taken out of context so many times" and represents "the worst thing ever," Mullenweg said in a new podcast interview with The Verge. The dispute began when Mullenweg accused WP Engine of "free-riding" on WordPress's open-source ecosystem without contributing adequate resources back to the project. Mullenweg filed a lawsuit against WP Engine while cutting off the company's access to core WordPress technologies. WP Engine countersued, and Automattic was forced to reverse some retaliatory measures. The controversy triggered significant internal upheaval at Automattic. The company offered "alignment" buyouts to employees who disagreed with the direction, reducing headcount from a peak of 2,100 to approximately 1,500 people. Mullenweg said this was "probably the fourth big time" WordPress has faced such community controversy, though the first in the current media landscape. WordPress powers 43% of websites globally. Mullenweg said he wants to return to "the most collaborative version of WordPress possible" but noted the legal proceedings continue with both sides spending "millions of dollars a month on lawyers."
