Atmospheric carbon dioxide hit a new record in April, averaging about 431 parts per million at NOAA's Mauna Loa Observatory. That's up from under 320 ppm when the site began measurements in 1958. Scientific American reports: Greenhouse gases, such as carbon dioxide, are measured as a proportion of the total atmosphere. The numbers are presented as the number of molecules of a particular gas out of a million total molecules, or ppm. Climate scientist Zachary Labe of Climate Central, a nonprofit that researches climate change, says the new record is "depressing" but not unexpected. "It's just another sign that carbon dioxide continues to increase in our atmosphere as our planet continues to warm," he says. "For many climate scientists, this is just 'here it is again, another record in the wrong direction.'" Labe explains that the amount of CO2 in the atmosphere tends to peak in April each year as decaying plants release greenhouse gases after winter. Some of that CO2 gets reabsorbed by plants as they grow during the warmer months. But NOAA's data show a worrying trend, with the average monthly amount of CO2 steadily increasing. [...] Although the amount of CO2 in the atmosphere has continued to rise, there was a reduction in U.S. emissions in 2023 and 2024. That trend, however, was reversed in 2025, at least partially because of the increased electricity demand from artificial intelligence data centers. Still, Labe says there are reasons for optimism as the use of renewable energy sources such as solar and wind expands.

An anonymous reader quotes a report from CNBC: OpenAI President Greg Brockman concluded his testimony on Tuesday, where he largely rebutted Elon Musk's account of the early years of the startup and negotiations that occurred at the company. Brockman testified that he never made any commitments to Musk about the company's corporate structure, and he never heard anyone else make them. He emphasized that OpenAI is still governed by a nonprofit. "This entity remains a nonprofit," Brockman said, referring to the OpenAI foundation. "It is the best-resourced nonprofit in the world." [...] Brockman, who spoke from the witness stand in federal court in Oakland, California, over the course of two days, also revealed that Musk had enlisted several OpenAI employees to do months of free work for him at Tesla, Musk's electric vehicle company. That work mainly included efforts to overhaul the company's approach to developing self-driving technology as part of the Autopilot team there in 2017. During his two days on the stand, Brockman answered questions about his personal financial ambitions, his understanding of OpenAI's structure and Musk's involvement at the company, which they co-founded with other executives in 2015. In Musk's testimony last week, the Tesla and SpaceX CEO said that the time, money and resources he poured into OpenAI had been integral to the company's success. He repeatedly said that he helped recruit the company's top talent. Brockman said Tuesday that while Musk was helpful in convincing some employees to take the leap to join OpenAI, he was a polarizing figure for others. "Elon had a reputation of being an extremely hard driver," Brockman said. He added that "certain candidates were very attracted" by Musk's involvement at OpenAI, and that "certain candidates were very turned off." Musk testified last week that a former OpenAI researcher named Andrej Karpathy joined Tesla, but only after he had planned to leave the startup already. Brockman said that Musk, after he hired Karpathy, approached him with "an apology and a confession," about the hire, and that neither Musk nor Karpathy had told him the researcher planned to leave OpenAI before that. Musk was generally not very available for meetings and conversations, Brockman said, so he relied on employees, including Sam Teller and former OpenAI board member Shivon Zilis, as proxies. Brockman testified that open sourcing OpenAI's technology was "not a topic of conversation" during Musk's time with the nonprofit, despite Musk's claims that it was supposed to be central to the organization. He also described tense 2017 negotiations over a possible for-profit arm, saying Musk became angry when equity stakes were discussed. "He said Musk declined the proposal during an in-person meeting, then tore a painting of a Tesla Model 3 car off the wall, and began storming out of the room," reports CNBC. He also demanded to know when the cofounders would leave the company. Brockman further said Musk wanted control of OpenAI because he disliked situations where he lacked control, citing Zip2 and SolarCity as examples Musk had raised. He also testified that Musk partly wanted control to help fund his broader SpaceX ambition of building a "city on Mars." CNBC notes the trial will resume at 8:30 a.m. PT on Wednesday, with Shivon Zilis expected to testify. She is the mother of four of Musk's children and a former OpenAI board member.

Apple has agreed to a proposed $250 million settlement over claims that it misled iPhone buyers about the availability of Apple Intelligence and its upgraded Siri features. The settlement would cover U.S. buyers of the iPhone 16 lineup and iPhone 15 Pro models between June 10, 2024, and March 29, 2025. The Verge reports: The settlement will resolve a 2025 lawsuit, alleging Apple's advertisements created a "clear and reasonable consumer expectation" that Apple Intelligence features would be available with the launch of the iPhone 16. The lawsuit claimed Apple's products "offered a significantly limited or entirely absent version of Apple Intelligence, misleading consumers about its actual utility and performance." Apple brought certain AI-powered features to the iPhone 16 weeks after its release, and delayed the launch of its more personalized Siri, which is now expected to arrive later this year. Last April, the National Advertising Division recommended that Apple "discontinue or modify" its "available now" claim for Apple Intelligence. Apple also pulled an iPhone 16 ad showing actor Bella Ramsey using the AI-upgraded Siri.

There is a persistent misconception among sighted developers: if an application runs in a terminal, it is inherently accessible. The logic assumes that because there are no graphics, no complex DOM, and no WebGL canvases, the content is just raw ASCII text that a screen reader can easily parse. The reality is different. Most modern Text User Interfaces (TUIs) are often more hostile to accessibility than poorly coded graphical interfaces. The very tools designed to improve the Developer Experience (DX) in the terminal-frameworks like Ink (JS/React), Bubble Tea (Go), or tcell-are actively destroying the experience for blind users. ↫ Casey Reeves The core reason should be obvious: the command-line interface, at its core, is just a stream of data with the newest data at the bottom, linearly going back in time as you go up. Any screen reader can deal with this fairly easily, and while I personally have no need for such a tool, I've heard from those that do that kernel-level screen readers are quite good at what they do. TUIs, or text-based user interfaces, made with modern frameworks are actually very different: they're "2D grid of pixels, where every character cell is a pixel. abandons the temporal flow for a spatial layout." It should become immediately obvious that screen readers won't really know what to do with this, and Reeves gives countless examples, but the short version is this: the cursor jumps all over the place with every screen update, which makes screen readers go nuts. Various older TUIs, made in a time well before these modern TUI frameworks came about, were designed in a much more terminal-friendly way, or give you options to hide the cursor to solve the problem that way. Irssi, for example, uses VT100 scrolling regions instead of redrawing the whole screen every time something changes. I had never really stopped to think about TUIs and screen readers, as is common among us sighted people. The problems Reeves describes seem to stem not so much from TUIs being inherently inaccessible, but from modern frameworks not actually making use of the terminal's core feature set. I really hope this Reeves' article shines a light on this problem, and that the people developing these modern TUIs start taking accessibility more seriously.

Backing up in modern times, we've had ZFS snapshots and replication to make this task extremely easy. However, you may not have access to another ZFS endpoint for replication, need to diversify risk by using a non-ZFS tool for backup, or are simply using UFS2, living the old skool life. For these situations, my first recommendation is to lean on Tarsnap for its ease of use and simplicity, making restoration just as easy as backing up. But some situations call for a different approach. Maybe you have a strict firewall at your company that doesn't allow Tarsnap data streams to egress from your corporate network, or you have internal/easy access to storage endpoints, such as S3-compatible object storage or a large-file storage location with SFTP access. When you are faced with the latter, the duplicity (sysutils/duplicity in ports) utility is available as an easily installable package onto your FreeBSD system. ↫ Jason Tubnor at the FreeBSD Foundation The rest of the article explains how to use duplicity on FreeBSD for the purpose described above.

Earlier this year, Mac OS and Windows NT-capable ROMs were discovered for Apple's unique AIX Network Server. Cameron Kaiser has since spent more time digging into just how capable these ROMs are, and has published another one of his detailed stories about his efforts. Well, thanks to Jeff Walther who generously built a few replica ROM SIMMs for me to test, we can now try the "2.0" MacOS ROMs on holmstock, our hard-working Apple Network Server 700 test rig (stockholm, my original ANS 500, is still officially a production unit). And there are some interesting things to report, especially when we pit the preproduction ROMs and this set head-to-head in MacBench, and even try booting Rhapsody on it. ↫ Cameron Kaiser A great read, as always.
