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!

Apple, which spent years as TSMC's undisputed top customer and helped the Taiwanese foundry become the semiconductor industry's most important manufacturer, is now fighting for production capacity as Nvidia's AI chip orders consume an ever-larger share of the company's leading-edge wafer supply. TSMC CEO CC Wei visited Cupertino last August to deliver unwelcome news: Apple would face the largest price increase in years and the iPhone maker would no longer have guaranteed access to production capacity across TSMC's nearly two dozen fabs. According to Culpium analysis and its supply chain sources, Nvidia likely overtook Apple as TSMC's largest customer in at least one or two quarters of 2025. TSMC's revenue climbed 36% last year to $122 billion, the company reported Thursday.

Wikipedia turns 25 today, and the online encyclopedia is celebrating that with an announcement that it has signed new licensing deals with a slate of major AI companies -- Amazon, Microsoft, Meta Platforms, Perplexity and Mistral AI. The deals allow these companies to access Wikipedia content "at a volume and speed designed specifically for their needs." The Wikimedia Foundation did not disclose financial terms. Google had already signed on as one of the first enterprise customers back in 2022. The agreements follow the Wikimedia Foundation's push last year for AI developers to pay for access through its enterprise platform. The foundation said human traffic had fallen 8% while bot visits -- sometimes disguised to evade detection -- were heavily taxing its servers. Wikipedia founder Jimmy Wales said he welcomes AI training on the site's human-curated content but that companies "should probably chip in and pay for your fair share of the cost that you're putting on us." The site remains the ninth most visited on the internet, hosting more than 65 million articles in 300 languages maintained by some 250,000 volunteer editors.

Anthropic's fourth installment of its Economic Index, drawing on an anonymized sample of two million Claude conversations from November 2025, finds that AI is changing how people work rather than whether they work at all. The study tracked usage across the company's consumer-facing Claude.ai platform and its API, categorizing interactions as either automation (where AI completes tasks entirely) or augmentation (where humans and AI collaborate). The split came out to 52% augmentation and 45% automation on Claude.ai, a slight shift from January 2025 when augmentation led 55% to 41%. The share of jobs using AI for at least a quarter of their tasks has risen from 36% in January to 49% across pooled data from multiple reports. Anthropic's researchers also found that AI delivers its largest productivity gains on complex work requiring college-level education, speeding up those tasks by a factor of 12 compared to 9 for high-school-level work. Claude completes college-degree tasks successfully 66% of the time versus 70% for simpler work. Computer and mathematical tasks continue to dominate usage, accounting for roughly a third of Claude.ai conversations and nearly half of API traffic.

White-collar workers stuck in a cycle of layoffs and stagnant wages might want to look past the traditional tech, finance and media job postings to an unexpected source of opportunity: the blue-collar sector, which faces a labor shortage and is seeing rapid transformation through private-equity investment. These jobs are generally less vulnerable to AI, and the earning trajectory can be steep, the WSJ writes. At Crash Champions, a car-repair chain that has grown from 13 locations in 2019 to about 650 shops across 38 states, service advisers start at roughly $60,000 after a six-month apprenticeship and can double that within 18 months, according to CEO Matt Ebert. Directors overseeing multiple locations earn more than $200,000. Power Home Remodeling, a PE-backed construction company, says tech sales professionals earning $85,000 to $100,000 could make lateral moves after a 10-week training program. The share of workers in their early 20s employed in blue-collar roles rose from 16.3% in 2019 to 18.4% in 2024, according to ADP -- five times the increase among 35- to 39-year-olds.

An anonymous reader quotes a report from TechCrunch: Over the weekend, Neel Somani, who is a software engineer, former quant researcher, and a startup founder, was testing the math skills of OpenAI's new model when he made an unexpected discovery. After pasting the problem into ChatGPT and letting it think for 15 minutes, he came back to a full solution. He evaluated the proof and formalized it with a tool called Harmonic -- but it all checked out. "I was curious to establish a baseline for when LLMs are effectively able to solve open math problems compared to where they struggle," Somani said. The surprise was that, using the latest model, the frontier started to push forward a bit. ChatGPT's chain of thought is even more impressive, rattling off mathematical axioms like Legendre's formula, Bertrand's postulate, and the Star of David theorum. Eventually, the model found a Math Overflow post from 2013, where Harvard mathematician Noam Elkies had given an elegant solution to a similar problem. But ChatGPT's final proof differed from Elkies' work in important ways, and gave a more complete solution to a version of the problem posed by legendary mathematician Paul Erdos, whose vast collection of unsolved problems has become a proving ground for AI. For anyone skeptical of machine intelligence, it's a surprising result -- and it's not the only one. AI tools have become ubiquitous in mathematics, from formalization-oriented LLMs like Harmonic's Aristotle to literature review tools like OpenAI's deep research. But since the release of GPT 5.2 -- which Somani describes as "anecdotally more skilled at mathematical reasoning than previous iterations" -- the sheer volume of solved problems has become difficult to ignore, raising new questions about large language models' ability to push the frontiers of human knowledge. Somani examined the online archive of more than 1,000 Erdos conjectures. Since Christmas, 15 Erdos problems have shifted from "open" to "solved," with 11 solutions explicitly crediting AI involvement. On GitHub, mathematician Terence Tao identifies eight Erdos problems where AI made meaningful autonomous progress and six more where it advanced work by finding and extending prior research, noting on Mastodon that AI's scalability makes it well suited to tackling the long tail of obscure, often straightforward Erdos problems. Progress is also being accelerated by a push toward formalization, supported by tools like the open-source "proof assistant" Lean and newer AI systems such as Harmonic's Aristotle.

Games Workshop, the owner and operator of a number of hugely popular tabletop war games, including Warhammer 40,000 and Age of Sigmar, has banned the use of generative AI in its content and design processes. IGN reports: Delivering the UK company's impressive financial results, CEO Kevin Rountree addressed the issue of AI and how Games Workshop is handling it. He said GW staff are barred from using it to actually produce anything, but admitted a "few" senior managers are experimenting with it. Rountree said AI was "a very broad topic and to be honest I'm not an expert on it," then went on to lay down the company line: "We do have a few senior managers that are [experts on AI]: none are that excited about it yet. We have agreed an internal policy to guide us all, which is currently very cautious e.g. we do not allow AI generated content or AI to be used in our design processes or its unauthorized use outside of GW including in any of our competitions. We also have to monitor and protect ourselves from a data compliance, security and governance perspective, the AI or machine learning engines seem to be automatically included on our phones or laptops whether we like it or not. We are allowing those few senior managers to continue to be inquisitive about the technology. We have also agreed we will be maintaining a strong commitment to protect our intellectual property and respect our human creators. In the period reported, we continued to invest in our Warhammer Studio -- hiring more creatives in multiple disciplines from concepting and art to writing and sculpting. Talented and passionate individuals that make Warhammer the rich, evocative IP that our hobbyists and we all love."

The UK government has awarded guaranteed electricity prices to offshore wind projects totaling 8.4 GW in a bid to revive wind development, attract nearly $30 billion in private investment, and stabilize energy costs. The New York Times reports: On Wednesday, the British government said that it would provide guaranteed electricity prices for a group of wind farms off England, Scotland and Wales that would, once built, provide power for 12 million homes. The 8.4 gigawatts, a power capacity measure, that won support is the largest amount that has been achieved in an auction in Britain. The government said that these wind farms could lead to 22 billion pounds, or almost $30 billion, in private investment. The government holds regular auctions, roughly on an annual basis. Results have been improving after a failed auction in 2023 that produced no bids from developers. The government almost doubled its original budget for the recent auction to about 1.8 billion pounds per year. To encourage renewable energy sources like offshore wind, Britain offers a price floor to provide certainty for investors. The average floor, or strike price, from the auction on Wednesday was about 91 pounds, or $122 per megawatt-hour, in 2024 prices, up about 11 percent from the last auction. Over the past year the wholesale price for electricity in Britain was on average about 79 pounds, according to Drax Electric Insights, a market analysis website. The bulk of the planned wind farms that won price supports will be off eastern England. Support will also go to wind farms off Scotland and Wales. The British government wants at least 95 percent of the country's electricity generation to come from clean sources by 2030. Political consensus for ambitious climate goals is eroding in Britain, but the government of Prime Minister Keir Starmer believes that an enormous bet on clean energy, especially offshore wind, is necessary to protect consumers from volatile fossil fuel prices.

An anonymous reader quotes a report from DealBook: Fifteen years ago, Daniel Ek broke into America's digital-content wars with his streaming music start-up, Spotify, which has turned into a publicly traded company with a $110 billion market value. Now he and his business partner, the Swedish entrepreneur Hjalmar Nilsonne, aim to crack a higher-stakes consumer market: American health care. The pair plan to bring Neko Health, the health tech start-up they founded in 2018, to New York this spring, DealBook is first to report. Mr. Ek and Mr. Nilsonne hope to capitalize on the growing number of prevention-minded Americans who are hungry to track their biometric data. Whether through wearables like Oura rings or more intensive screenings, consumers are turning to technology to improve their health and help spot the early onset of some big killers, including cardiovascular and metabolic diseases. The United States will be the third market, after Sweden and Britain, for Neko Health, which offers full-body diagnostic scans and is valued at roughly $1.7 billion. [...] Mr. Nilsonne and Mr. Ek said Neko Health's big aim was to change the health care model, in which spending across much of the developed world skyrockets but longevity gains have stalled. They want to make their noninvasive scans as routine as an annual checkup. The company, which advertises its service as "a health check for your future self," did not say what the U.S. scans would cost. But in Stockholm, an hourlong visit at one of its clinics costs 2,750 Swedish krona (about $300). Prenuvo's and Ezra's most comprehensive scans can cost $3,999. [...] Neko Health's technology differs from that of many of its U.S. rivals. It does not use M.R.I. or X-rays, instead relying on scores of sensors and cameras and a mix of proprietary and off-the-shelf technologies to measure heart function and circulation, and to photograph and map every inch of a patient's body looking for cancerous lesions. At the moment, the company's biggest challenge is scaling. [...] Mr. Nilsonne said Neko Health scans have detected the early onset of diseases or serious medical conditions for thousands of its patients. But the medical community is divided on the need for proactive screening technologies. The fear is that mass adoption could spur a wave of false positives and send healthy people to seek follow-up medical advice, overwhelming an already swamped health care system. Mr. Ek and Mr. Nilsonne believe they have built a better solution. And now they're ready to test it in the U.S. market.
