Researchers from Carnegie Mellon, MIT, NYU, and Stanford have built an AI called Ataraxos that finally cracked Stratego, beating four-time world champion Pim Niemeijer 15 games to one with four draws. Its key advantage was a second neural network that estimates the identities of hidden enemy pieces, letting the system search plausible game states rather than brute-force a massive hidden-information space. Ars Technica reports: Just like [DeepMind's DeepNash, introduced in 2022], Ataraxos learned by playing against itself -- 163 million games in total. In these self-play sessions, moves that led to wins were reinforced and played more often in future matches, while moves that led to losses were played less, which was the same simple training idea. The difference was in how much Ataraxos adjusted after each game, because hidden information tends to send self-play learning algorithms around in circles. The team addressed this by making big, bold changes in strategy early in training and small, careful ones later. The even bigger innovation was something DeepNash never had: thinking ahead before each move. AIs like AlphaGo refine their general strategy with a search just before acting. DeepMind couldn't make that work in Stratego because the search space was too large, leaving it an open question whether it was worth trying. "This is one of the things that we did figure out how to do," Farina said. The solution was a second neural network, a belief model, trained to guess the opponent's hidden pieces based on how they had been moving. This way, instead of iterating through every possible arrangement, Ataraxos samples plausible ones, plays out candidate moves in each, and picks based on how they turned out. And it shows in its playstyle. [...] DeepNash was trained for two to three months on 1,024 of Google's specialized chips, a run the Ataraxos team estimates would cost $3 million to $4.5 million at 2025 prices. Ataraxos, in contrast, needed 16 GPUs for a week, plus an additional four GPUs for four days to train the belief model. Farina and lead author Samuel Sokota achieved this efficiency by writing a simulator that runs millions of moves per second on graphics cards. "At the scale that we are in academia, we don't really have access to an entire field of GPUs," Farina said. The algorithm also learned far faster -- it played about 34 times fewer games than DeepNash, and still ended up much stronger. The findings have been published in the journal Nature.

Longtime Slashdot submitter theodp writes: GeekWire reports that the University of Washington has moved its Global Innovation Exchange {GIX) program to Microsoft's campus in a rent-free deal (UW News release). GIX, an institute supporting tech leaders that offers an MS in Technology Innovation, is the first UW program to set up full-time operations at Microsoft, whose headquarters are just across Lake Washington from the university's main campus. Microsoft provided a $42 million in-kind donation to establish the embedded facility; the UW is leasing the new 48,500-square-foot GIX space in Microsoft's Building 92 rent-free. GIX debuted in 2015 as a partnership of the UW and China's Tsinghua University and received $70 million in Microsoft support at the now-abandoned GIX location in Bellevue (the Steve Ballmer Building), although indications are that a long-term arrangement did not come together as intended. In a Thursday LinkedIn post, Microsoft President Brad Smith wrote: "Last night we opened a door unlike any other. At the heart of Microsoft's campus, step into the new home of the UW's Global Innovation Exchange (GIX) and you cross from Microsoft into the University of Washington. No one has ever put a great research university and a leading technology company under the same roof quite like this. As far as I know, no one has even tried. The timing matters. Artificial intelligence is advancing fast. The question is whether the people building it understand the world it's changing. This calls for a new style of education and leadership. We need leaders who understand the technology deeply and see things through other people's eyes. Leaders who learn by collaborating on real projects with people from different countries and disciplines. That's what GIX is built for. Students will learn from faculty across the UW, take classes taught by Microsoft employees, and be mentored by people from across our industry here in the Pacific Northwest." Interestingly, Smith's contention that UW GIX students will benefit from a 'new style' of Microsoft and industry-influenced education sounds a lot like Smith's contention that K-12 school children are better off thanks to a new style of Microsoft and industry-influenced education. In an interview last month, Coding Kids: Big Tech's Battle to Remake Public Schools author Natasha Singer told NPR (podcast, transcript), "For my book, I spoke to Brad Smith, who's the president of Microsoft, and he has been one of the leaders in the tech industry pushing for [K-12] computer science [and now AI literacy] in schools. [...] And Brad Smith said, philanthropy in the private sector is doing this work because public schools have failed to do what they were supposed to do. And his view is that public schools should be teaching modern subjects like computer science, and they were not equipped to do it fast enough and the tech industry stepped in to help. And is it better than if schools were able to do this themselves? He said, no, but it's certainly better than nothing. And he said to me, you know, think about where we would be on computer science if the tech industry hadn't stepped up. [...] Well, I've been having this conversation with him for 10 years, and when we started having it 10 years ago, I said to him, I get that, but when big tech companies put their finger on the scale, it tips education in certain ways that not only favor the tech industry but can obscure equally or more important things." So, is "The University of Washington at Microsoft" a good or bad idea?

Apple says it will tighten macOS Full Disk Access controls as increasingly capable AI agents raise the risks of apps gaining broad access to users' files, messages, mail, and browsing history. TechCrunch reports: Days after a journalist claimed that Meta's Muse app on Mac read their private messages -- a claim that Meta disputed -- Apple announced that it's introducing additional controls around a setting called "Full Disk Access" on macOS. The feature was designed to allow backups to function properly, but AI agents have now increased "the risks associated with this level of access," Apple said. [...] In Muse's case, the AI optionally allows users to enable Full Disk Access. This setting, Apple explains, gives an app permission to access files, mail, messages, and even browsing history. "Some developers are using Full Disk Access in ways that could put users at risk, exposing everything on their systems... without users' full knowledge and understanding," Apple said in a new blog post aimed at developers. The company says that, going forward, it will introduce new controls aimed at ensuring that users who "genuinely wish to grant an app this extraordinary level of access" can do so only with "every explicit user action." "Addressing this is critical. As AI agents become increasingly capable and autonomous, the risks associated with this level of access will grow substantially. We are committed to ensuring users clearly understand these risks before granting such access, so they can make informed decisions about their own data and privacy," Apple wrote.

Google launched its Googlebooks platform a week ago, and a lot of people were wondering what this meant for Chrome OS and Chromebooks. Since Googlebooks and its Android-based Googlebook OS lack the management frameworks markets like schools require, Chromebooks will continue to be available for now, until such time Googlebooks catch up in that regard. However, in a support document, Google states that update support for all Chromebook devices will end in 2034: ChromeOS devices will continue to receive regular updates and security patches through mid-2034. For qualifying devices purchased today whose 10-year support lifecycle extends beyond 2034, Google is committed to supporting your transition to Googlebook OS, with many devices offering direct migration paths. ↫ Google support document Google promised 10 years of updates for all Chromebooks, and it's now breaking that promise for anyone buying a Chromebook between now and whenever the last Chromebook rolls off the production line. Sadly, we live in a world where corporations are free to make and break whatever promises they want virtually free of consequences, and as society we're so used to it that anti-consumer behaviour like this barely elicits a shrug. Google does state that "many newer commercial Chromebook models will be capable of upgrading to Googlebook OS", but that, too, is just another promise - and a vague, one at that - so who knows how many devices will actually be capable of upgrading out in the real world. On top of that, we have no idea if Googlebooks will just be yet another in a long line of quickly abandoned Google tablet/laptop projects, further adding to the uncertainty. Stuff like this should not be legal.

In June 2008 Apple announced Mac OS X Snow Leopard, proudly boasting that it would have "no new features". Instead of piling on new things, Snow Leopard aimed to build on the success of its predecessor, Leopard, opting to focus on under-the-hood performance and stability improvements throughout the system. 18 years later, Apple is taking a similar approach with macOS 27. Golden Gate aims to fix the missteps of last year's Tahoe, promising an expansive set of improvements and "a more responsive and delightful experience". Does it hold up? Here are just some of the bugs I've encountered in my daily use over the past couple of weeks. ↫ Chester at SquareOrbits I'm getting some real Windows 11 vibes from this long list of bugs and issues, further underlining my perception that Apple completely lost the plot when it comes to Mac OS X (in the past) and MacOS (today). These are not the kind of things you'd find in the heydays of Mac OS X, back when I was a devout user, and makes me glad I abandoned ship long, long ago (around the time of the Intel transition). I don't see stuff like this in GNOME or KDE, and while not nearly as bad as Windows 11, the cracks are obvious. I am by no means an expert at how Apple is run and how it organises itself, but as a layperson I do wonder if the company is simply trying to do too much - too many different platforms, too many different crucial components it all develops internally, too many different markets to please. Things are going to fall through the cracks when you try to keep this many plates spinning.

A brand new Tcl/Tk release, in the form of Tcl/Tk 9.1. The new features in Tcl are a bit difficult for me to properly parse as a non-developer, but Tk's improvements are easy to understand: it brings supports for screen readers, initial supports for bidirectional and RTL scripts, improved listbox selection colours, and more. It also happens to drop support for Windows XP appearances, if that's something that matters to you.

Over the last few weeks, we have been doing research on the integration of our official distribution packages when installed on a target system. In this context we have been looking at the current uses of alpm-install-scriptlet(5) files and alpm-hooks(5) in around 120 package source repositories (alpm-source-repo(7)) to better understand the underlying functionality and use-cases these two integrations offer and target. In this article we are going to look at how these two systems work, how Arch Linux is currently using them and attempt to provide suggestions for when to use which.

This is just a short note on my blog that I have resigned from Arch Linux a package maintainer, developer and security team. I've spent around 10 years as an AUR maintainer, security team, Package Maintainer and then Developer. I implemented support for debug packages, did the initial POC work that would become the git migration and even somehow managed to pull of an online conference during The Plague with the help of others.
