  • Ruby on Rails Creator Says AI Coding Tools Still Can't Match Most Junior Programmers
    by msmash on 16/01/2026 at 4:06 pm

    AI still can't produce code as well as most junior programmers he's worked with, David Heinemeier Hansson, the creator of Ruby on Rails and co-founder of 37 Signals, said on a recent podcast [video link], which is why he continues to write most of his code by hand. Hansson compared AI's current coding capabilities to "a flickering light bulb" -- total darkness punctuated by moments of clarity before going pitch black again. At his company, humans wrote 95% of the code for Fizzy, 37 Signals' Kanban-inspired organization product, he said. The team experimented with AI-powered features, but those ended up on the cutting room floor. "I'm not feeling that we're falling behind at 37 Signals in terms of our ability to produce, in terms of our ability to launch things or improve the products," Hansson said. Hansson said he remains skeptical of claims that businesses can fire half their programmers and still move faster. Despite his measured skepticism, Hansson said he marvels at the scale of bets the U.S. economy is placing on AI reaching AGI. "The entire American economy right now is one big bet that that's going to happen," he said. Read more of this story at Slashdot.

  • China Clamps Down on High-Speed Traders, Removing Servers
    by msmash on 16/01/2026 at 3:26 pm

    An anonymous reader shares a report: China is pulling the plug on a key advantage held by high-frequency traders, removing servers dedicated to those firms out of local exchanges' data centers, according to people familiar with the matter. Commodities futures exchanges in Shanghai and Guangzhou are among those that have ordered local brokers to shift servers for their clients out of data centers run by the bourses, according to the people, who said the move was led by regulators. The change doesn't only affect high-frequency firms but they are likely to feel the biggest impact. The Shanghai Futures Exchange has told brokers they need to get equipment for high-speed clients out by the end of next month, while other clients need to do so by April 30, the people said. The clampdown will hit China's army of domestic high-frequency firms but will also impact a swathe of global firms that are active in the country. Citadel Securities, Jane Street Group and Jump Trading are among the foreign firms whose access to servers is being affected, the people said, asking not to be named as the matter is private.

  • Hard Drive Prices Have Surged By an Average of 46% Since September
    by msmash on 16/01/2026 at 2:40 pm

    Tom's Hardware: Extensive research into the pricing of some of the best hard drives on the market for large capacity, economical storage indicates that prices are beginning to increase sharply, with some of the most popular models on the market seeing increases upwards of 60%. According to research from ComputerBase, pricing analysis on 12 of the most popular mainstream drives on the market indicates an average price increase of 46% over the last 4 months. While the research and price checks on these drives track movement based on European prices (ComputerBase is a German outlet), Tom's Hardware checks on similar or identical SKUs in the U.S. indicate that the trends are indeed replicated, or perhaps worse, on the other side of the pond. CB reports that various drives like Seagate's IronWolf NAS line, Toshiba's Cloud Scale Capacity Drives, Western Digital's WD Red, and Seagate's BarraCuda lines are all showing price increases of between 23% and 66%. As noted, the average price increases clock in at 46% since September 2025. Read more of this story at Slashdot.

  • Code.org: Use AI In an Interview Without Our OK and You're Dead To Us
    by msmash on 16/01/2026 at 2:00 pm

    theodp writes: Code.org, the nonprofit backed by AI giants Microsoft, Google and Amazon and whose Hour of AI and free AI curriculum aim to make world's K-12 schoolchildren AI literate, points job seekers to its AI Use Policy in Hiring, which promises dire consequences for those who use AI during interviews or take home assignments without its OK. Explaining "What's Not Okay," Code.org writes: "While we support thoughtful use of AI, certain uses undermine fairness and honesty in the hiring process. We ask that candidates do not [...] use AI during interviews and take-home assignments without explicit consent from the interview team. Such use goes against our values of integrity and transparency and will result in disqualification from the hiring process." Interestingly, Code.org CEO Partovi last year faced some blowback from educators over his LinkedIn post that painted schools that police AI use by students as dinosaurs. Partovi wrote, "Schools of the past define AI use as 'cheating.' Schools of the future define AI skills as the new literacy. Every desk-job employer is looking to hire workers who are adept at AI. Employers want the students who are best at this new form of 'cheating.'" Read more of this story at Slashdot.

  • Amazon Is Buying America's First New Copper Output In More Than a Decade
    by BeauHD on 16/01/2026 at 1:00 pm

    An anonymous reader quotes a report from the Wall Street Journal: Amazon is turning to an Arizona mine that last year became the first new source of U.S. copper in more than a decade, to meet its data centers' ravenous appetite for the industrial metal. The mine was restarted as a proving ground for Rio Tinto's new method of unlocking low-grade copper deposits. Rio signed a two-year supply pact with Amazon Web Services, a vote of confidence for its Nuton venture, which uses bacteria and acid to extract copper from ore that was previously uneconomical to process. The move by Amazon is the latest example of a technology company rushing to secure the power and critical materials necessary to build and operate artificial-intelligence data centers. The Nuton copper will satisfy only a sliver of Amazon's needs. The biggest data centers each require tens of thousands of metric tons of copper for all the wires, busbars, circuit boards, transformers and other electrical components housed there. The 14,000 metric tons of copper cathode that Rio expects the Arizona Nuton project to yield over four years wouldn't be enough for one of those facilities. Rio deployed its bioleaching process in the recent restart of a mine east of Tucson and has partnerships to take the technology to several others in the Americas. The idea is to uncork the low-grade ore left behind at old mines and is key to Rio's plans to boost output when new discoveries are harder than ever to bring online and copper demand is surging. [...] "We work at the commodity level to find lower carbon solutions to drive our business growth," said Chris Roe, Amazon's director of worldwide carbon. "That means steel, and that means concrete, and it absolutely means copper with regard to our data centers." Roe said the copper will be routed to companies that produce components for Amazon's data centers. As part of the deal, Amazon is supplying Rio with cloud-computing and data analytics to optimize Nuton's recovery rates and help the miner expand production. Read more of this story at Slashdot.

  • 'Star Wars' Boss Kathleen Kennedy Steps Down From Lucasfilm
    by BeauHD on 16/01/2026 at 10:00 am

    After more than 13 years leading Lucasfilm, Kathleen Kennedy is stepping down. "When George Lucas asked me to take over Lucasfilm upon his retirement, I couldn't have imagined what lay ahead," said Kennedy. "It has been a true privilege to spend more than a decade working alongside the extraordinary talent at Lucasfilm." The Associated Press reports: The Walt Disney Co. announced Thursday that it will now turn to Dave Filoni to steer "Star Wars," as president and chief creative officer, into its sixth decade and beyond. Filoni, who served as the chief commercial officer of Lucasfilm, will inherit the mantle of one of the movies marquee franchises, alongside Lynwen Brennan, president and general manager of Lucasfilm's businesses, who will serve as co-president. Kennedy, Lucas' handpicked successor, had presided over the ever-expanding science-fiction world of "Star Wars" since Disney acquired it in 2012. In announcing Thursday's news, Bob Iger, chief executive officer of the Walt Disney Co. called her "a visionary filmmaker." Kennedy oversaw a highly lucrative but often contentious period in "Star Wars" history that yielded a blockbuster trilogy and acclaimed streaming spinoffs such as "The Mandalorian" and "Andor," yet found increasing frustration from longtime fans. Under Kennedy's stewardship, Lucasfilm amassed more than $5.6 billion in box office and helped establish Disney+ as a streaming destination -- achievements that easily validated the $4.05 billion Disney plunked down for the company. But Kennedy also struggled to deliver the big-screen magic that Lucas captured in the original trilogy from the late 1970s and early 1980s, and her relationship with "Star Wars" loyalists became a saga of its own.
