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!

You can find the timezone in Linux using the command line. The easiest way to do this is to type the "timedatectl" command and look for the "timezone" line when using modern Linux distros with systemd.

European manufacturers are facing a two-front assault from China that has German industry associations warning of deindustrialisation: on one side, artificially cheap Chinese goods are flooding into Europe, and on the other, Beijing has demonstrated its willingness to abruptly cut off access to critical inputs like rare earths and semiconductors. The alarm intensified in October when China added five rare earths to its export-licensing regime and then banned exports of computer chips made by Nexperia, a Dutch-headquartered but Chinese-owned chipmaker that supplies numerous European carmakers, according to The Economist. Several European firms warned of production stoppages, and some German companies put workers on leave without pay. Germany's trade deficit with China hit $76.52 billion last year and is expected to surge to around $100.87 billion this year, The Economist reported, driven by collapsing German exports and a rush of imports in categories like cars, chemicals, and machinery that were once German specialties. Chinese brands now account for 20% of Europe's hybrid market and 11% of electric vehicle sales. German cars command just 17% of the Chinese market, down from 27% in 2020. The rare earth controls were suspended for a year after the US and China struck a trade deal on October 30th, but the EU found itself a bystander to negotiations that directly affected its economy. Writing in the Financial Times, Robin Harding argues that China's explicit goal of self-sufficiency leaves Europe with few options. "There is nothing that China wants to import, nothing it does not believe it can make better and cheaper," he wrote, concluding that large-scale protectionism may be unavoidable if Europe wants to retain any industry at all.

An anonymous reader shares a report: It is shocking but not surprising. Lightning crackles on Mars, scientists reported on Wednesday. What they observed, however, were not jagged, high-voltage bolts like those on Earth, arcing thousands of feet from cloud to ground. Rather, the phenomenon was more like the shock you feel when you scuff your feet on the carpet on a cold winter morning and then touch a metal doorknob. "This is like mini-lightning on Mars," Baptiste Chide, a scientist at the Research Institute in Astrophysics and Planetary Science in Toulouse, France, said of the centimeter-scale electrical discharges. Dr. Chide and his colleagues reported the findings in a paper published on Wednesday in the journal Nature. The electrical sparks, although not as dramatically violent as on Earth, could play an important role in chemical reactions in the Martian atmosphere.

Dell has predicted PC sales will be flat next year, despite the potential of the AI PC and the slow replacement of Windows 10. From a report: "We have not completed the Windows 11 transition," COO Jeffrey Clarke said during Dell's Q3 earnings call on Tuesday. "In fact, if you were to look at it relative to the previous OS end of support, we are 10-12 points behind at that point with Windows 11 than we were the previous generation." Clarke said that means 500 million PCs can't run Windows 11, while the same number didn't need an upgrade to handle Microsoft's latest desktop OS. The COO therefore predicted the PC market will "flourish," but then defined the word as meaning "roughly flat" sales despite Dell chalking up mid-to high single digits PC sales growth over the last year.

Apple will retake its crown as the world's largest smartphone maker for the first time in more than a decade, lifted by the successful debut of a new iPhone series and a rush of consumers upgrading devices, according to Counterpoint Research. From a report: The iPhone 17 models introduced in September have been a hit both domestically in the US and in Apple's other critical market, China. They've enticed more people to upgrade, leading to double-digit year-over-year sales growth in both markets, according to the researchers. The US company also is benefiting from a cooling of US-China trade tensions and a depreciating dollar that has boosted purchases in emerging markets, they added. The growth will propel Apple past longtime rival Samsung this year, according to Counterpoint's figures. Shipments of the iPhone are set to grow at 10% in 2025, compared with 4.6% for Samsung.

An anonymous reader shares a report: AI is not a core part of operations at most of the world's central banks and digital assets are off the table, according to a survey released on Wednesday by the Official Monetary and Financial Institutions Forum. The working group of 10 central banks from Europe, Africa, Latin America and Asia managing roughly $6.5 trillion in assets also found that the institutions that have delved deepest so far into AI are the most cautious about the risks. The primary concern is that AI-driven behaviour could "accelerate future crises," the survey showed. "AI helps us see more, but decisions must remain with people," one participant was quoted as saying in the group's report. More than 60% of respondents said that AI tools - which have sparked layoffs already at technology companies and retail and investment banks - are not yet supporting core operations.
