DNSCrypt-proxy is an open-source and free software designed to encrypt DNS traffic, thus protecting it from eavesdropping and manipulation. This is also useful to evade DNS censorship when DNSCrypt-proxy is configured correctly with Wireguard or OpenVPN. Further, DNSCrypt-proxy can configured to block malware, trackers, and internet ads. In Debian 11 and 12, using DNSCrypt-proxy can enhance privacy and security by preventing DNS spoofing attacks, DNS hijacking, and surveillance of DNS traffic. It ensures that DNS queries are encrypted, authenticated, and secure, thereby safeguarding users' browsing activities and sensitive information. Let us see how to install dnscrypt-proxy on Debian Linux 11 and 12.

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!

Rivian's stock skyrocketed 27% Friday after the electric car maker "shocked the market with strong earnings results," reports the Los Angeles Times, "proving itself an outlier in the EV market, which has been struggling with the end of government subsidies and cooling consumer excitement." They add that Rivian's strong earnings results suggest that "after years of struggling with losses, it may have at last found a path to profitability." On Thursday, Rivian reported gross profits for 2025 of $144 million, compared with a net loss in 2024 of $1.2 billion... Rivian credited the swing to gross profit to "strong software and services performance, higher average selling prices, and reductions in cost per vehicle..." Rivian delivered 42,247 vehicles in 2025 and produced 42,284 vehicles. The company still reported a $432-million net loss for the year for automotive profits, an improvement from 2024. But Rivian's software and services revenue grew more than threefold to $1.55 billion for the year, reports TechCrunch. "And the joint venture with Volkswagen Group was behind most of that growth, according to Rivian." VW and Rivian formed a technology joint venture in 2024 that is worth up to $5.8 billion. The joint venture is milestone-based and in 2025 Rivian hit the mark, which meant a $1 billion payout in the form of a share sale. Under the terms of the JV, Rivian will supply VW Group with its existing electrical architecture and software technology stack... Rivian is expected to receive an additional $2 billion of capital as part of the joint venture in 2026, CFO Claire McDonough said Thursday on the company earnings call... And while the funds provide a hefty stopgap, Rivian's financial success in 2026 will hinge largely on the rollout of its next EV, the R2 [priced around $45,000].

Bloomberg reports: India tightened rules governing social media content and platforms, particularly targeting artificially generated and manipulated material, in a bid to crack down on the rapid spread of misinformation and deepfakes. The government on Tuesday (Feb 10) notified new rules under an existing law requiring social media firms to comply with takedown requests from Indian authorities within three hours and prominently label AI-generated content. The rules also require platforms to put in place measures to prevent users from posting unlawful material... Companies will need to invest in 24-hour monitoring centres as enforcement shifts toward platforms rather than users, said Nikhil Pahwa, founder of MediaNama, a publication tracking India's digital policy... The onus of identification, removal and enforcement falls on tech firms, which could lose immunity from legal action if they fail to act within the prescribed timeline. The new rules also require automated tools to detect and prevent illegal AI content, the BBC reports. And they add that India's new three-hour deadline is "a sharp tightening of the existing 36-hour deadline." [C]ritics worry the move is part of a broader tightening of oversight of online content and could lead to censorship in the world's largest democracy with more than a billion internet users... According to transparency reports, more than 28,000 URLs or web links were blocked in 2024 following government requests... Delhi-based technology analyst Prasanto K Roy described the new regime as "perhaps the most extreme takedown regime in any democracy". He said compliance would be "nearly impossible" without extensive automation and minimal human oversight, adding that the tight timeframe left little room for platforms to assess whether a request was legally appropriate. On AI labelling, Roy said the intention was positive but cautioned that reliable and tamper-proof labelling technologies were still developing. DW reports that India has also "joined the growing list of countries considering a social media ban for children under 16." "Young Indians are not happy and are already plotting workarounds."

While serving his 25-year prison sentence, "convicted former cryptocurrency mogul Sam Bankman-Fried on Tuesday requested a new federal trial," reports Courthouse News, "based on what he says is newly discovered evidence concerning his company's solvency and its ability to repay all FTX customers for what prosecutors portrayed as the looting of $8 billion of his customers' money..." Bankman-Fried says evidence disclosed since his trial disproves prosecutors' case about Bankman-Fried's hedge fund running a multi-billion deficit of FTX customer funds, and instead shows that FTX always had sufficient assets to repay the cryptocurrency platform's customer deposits in full. "What it faced was a short-term liquidity crisis caused by a run on the exchange, not insolvency," he wrote... Bankman-Fried also accuses the Department of Justice of coercing a guilty plea and cooperation deal from Nishad Singh — a close friend of Bankman-Fried's younger brother — who testified at trial as a cooperating witness... Bankman-Fried says in the motion that prior to being pressured into a guilty plea, Singh's initial proffer to investigators "contradicted key parts of the government's version of events. But following threats from the government, Mr. Singh changed his proffers to fit the government's narrative and pleaded guilty to charges carrying up to 75 years in prison, with a promise from the prosecution that it would recommend little or no jail time if it concluded that his assistance in prosecuting Mr. Bankman-Fried was 'substantial,'" he wrote in the petition... Additionally, Bankman-Fried requested that U.S. District Judge Lewis Kaplan, who presided over his 2023 trial, recuse himself from ruling on this motion, "because of the manifest prejudice he has demonstrated towards Mr. Bankman-Fried." "Bankman-Fried's mother, Stanford Law School professor Barbara Fried, filed his self-represented bid for a new trial on his behalf in Manhattan federal court..."
