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 Ars Technica, written by Dan Goodin: Two security professionals who were arrested in 2019 after performing an authorized security assessment of a county courthouse in Iowa will receive $600,000 to settle a lawsuit they brought alleging wrongful arrest and defamation. The case was brought by Gary DeMercurio and Justin Wynn, two penetration testers who at the time were employed by Colorado-based security firm Coalfire Labs. The men had written authorization from the Iowa Judicial Branch to conduct "red-team" exercises, meaning attempted security breaches that mimic techniques used by criminal hackers or burglars. The objective of such exercises is to test the resilience of existing defenses using the types of real-world attacks the defenses are designed to repel. The rules of engagement for this exercise explicitly permitted "physical attacks," including "lockpicking," against judicial branch buildings so long as they didn't cause significant damage. [...] DeMercurio and Wynn's engagement at the Dallas County Courthouse on September 11, 2019, had been routine. A little after midnight, after finding a side door to the courthouse unlocked, the men closed it and let it lock. They then slipped a makeshift tool through a crack in the door and tripped the locking mechanism. After gaining entry, the pentesters tripped an alarm alerting authorities. Within minutes, deputies arrived and confronted the two intruders. DeMercurio and Wynn produced an authorization letter -- known as a "get out of jail free card" in pen-testing circles. After a deputy called one or more of the state court officials listed in the letter and got confirmation it was legit, the deputies said they were satisfied the men were authorized to be in the building. DeMercurio and Wynn spent the next 10 or 20 minutes telling what their attorney in a court document called "war stories" to deputies who had asked about the type of work they do. When Sheriff Leonard arrived, the tone suddenly changed. He said the Dallas County Courthouse was under his jurisdiction and he hadn't authorized any such intrusion. Leonard had the men arrested, and in the days and weeks to come, he made numerous remarks alleging the men violated the law. A couple months after the incident, he told me that surveillance video from that night showed "they were crouched down like turkeys peeking over the balcony" when deputies were responding. I published a much more detailed account of the event here. Eventually, all charges were dismissed.

The preprint repository arXiv will require all submissions to be written in English or accompanied by a full English translation starting February 11, a policy change that explicitly permits the use of AI translators even as research suggests large language models remain inconsistent at the task. Until now, authors only needed to submit an abstract in English. ArXiv hosts nearly 3 million preprints and receives more than 20,000 submissions monthly, though just 1% are in languages other than English. Ralph Wijers, chair of arXiv's editorial advisory council, advises authors to verify any AI-generated translations. "Our own experience is that AI translation is good but not good enough," he says. A 2025 study from ByteDance Seed and Peking University ranked 20 LLMs on translation quality between Chinese and English; GPT-5-high scored nearly 77, just below the human expert benchmark of 80, but most models including GPT-4o, Claude 4, and Deepseek-V3 scored under 60.

An anonymous reader shares a report: The US is leading a huge global surge in new gas-fired power generation that will cause a major leap in planet-heating emissions, with this record boom driven by the expansion of energy-hungry datacenters to service AI, according to a new forecast. This year is set to shatter the annual record for new gas power additions around the world, with projects in development expected to grow existing global gas capacity by nearly 50%, a report by Global Energy Monitor (GEM) found. The US is at the forefront of a global push for gas that is set to escalate over the next five years, after tripling its planned gas-fired capacity in 2025. Much of this new capacity will be devoted to the vast electricity needs of AI, with a third of the 252 gigawatts of gas power in development set to be situated on site at datacenters. All of this new gas energy is set to come at a significant cost to the climate, amid ongoing warnings from scientists that fossil fuels must be rapidly phased out to avoid disastrous global heating.

An anonymous reader shares a report: U.S. life expectancy rose to a record high of 79 years in 2024, an increase of six months from the previous year, reflecting a sharp decline in deaths from COVID-19 and drug overdoses, the Centers for Disease Control and Prevention said on Thursday. According to a report from the CDC's National Center for Health Statistics, life expectancy improved for both men and women across races and among Hispanics, surpassing the previous peak set in 2014.

Microsoft wants you to know that it knows that Windows 11, now used by a billion users, has been testing your patience and announced that its engineers are being redirected to urgently address the operating system's performance and reliability problems through an internal process the company calls "swarming." "The feedback we're receiving from our community of passionate customers and Windows Insiders has been clear. We need to improve Windows in ways that are meaningful for people," Pavan Davuluri, president of Windows and devices, told The Verge. The company plans to spend the rest of 2026 focusing on pain points including system performance, reliability, and overall user experience. January has been particularly rough for Windows 11. Microsoft issued an emergency out-of-band update to fix shutdown issues on some machines, then released a second out-of-band fix a week later to address OneDrive and Dropbox crashes. Some business PCs are also failing to boot after the January update because they were left in an "improper state" after December's monthly update failed to install. Users have also grown frustrated by aggressive Edge and Bing prompts, constant OneDrive upselling nags, and Microsoft's push to require Microsoft accounts. The core members of the company's Windows Insider team recently moved to different roles. "Trust is earned over time and we are committed to building it back with the Windows community," Davuluri said.

The private equity industry is experiencing a quiet reckoning as hundreds of midsize firms find themselves trapped between investors who have lost patience and portfolios of companies they cannot sell at acceptable prices. "There is existential risk for a number [of funds] because of the fundraising environment," said Sunaina Sinha Haldea, global head of private capital advisory at Raymond James. "If existing investors don't come and support them, new investors are highly unlikely to." According to data from Preqin, the average buyout fund that closed in 2025 spent 23 months fundraising, up from 16 months in 2021, and the total number of funds raised fell to 1,191 from 2,679 over the same period. New York's Vestar Capital scrapped plans for its eighth fund in late 2024 and has not invested in a new portfolio company since 2023. The firm's assets under management dropped from $7 billion fifteen years ago to $3.3 billion in 2024. Three-year annualized returns through June 2025 for the Cambridge Associates U.S. Private Equity Index stand at 7.4%, trailing the MSCI World stock index by 11 percentage points annually. The average holding period for buyout deals has stretched to 6.3 years from 5.1 years in 2020. Blue-chip megafunds continue raising capital normally, but smaller firms face existential pressure.

Apple has acquired Q.AI, a secretive Israeli startup whose technology can analyze facial skin micro-movements to interpret "silent speech," in a deal valued at close to $2 billion that marks the iPhone maker's second-largest acquisition ever, according to backer GV (formerly Google Ventures). The four-year-old company was founded in Tel Aviv in 2022 by Aviad Maizels, Yonatan Wexler and Avi Barliya. Patents filed by Q.AI show its technology being deployed in headphones or smart glasses to enable non-verbal communication with an AI assistant. The acquisition comes as Meta's Ray-Ban smart glasses already let wearers talk to its AI, and Google and Snap are preparing to launch competing devices later this year.
