An anonymous reader quotes a report from Wired: OpenAI has fired an employee following an investigation into their activity on prediction market platforms including Polymarket, WIRED has learned. OpenAI CEO of Applications, Fidji Simo, disclosed the termination in an internal message to employees earlier this year. The employee, she said, "used confidential OpenAI information in connection with external prediction markets (e.g. Polymarket)." "Our policies prohibit employees from using confidential OpenAI information for personal gain, including in prediction markets," says spokesperson Kayla Wood. OpenAI has not revealed the name of the employee or the specifics of their trades. Evidence suggests that this was not an isolated event. Polymarket runs on the Polygon blockchain network, so its trading ledger is pseudonymous but traceable. According to an analysis by the financial data platform Unusual Whales, there have been clusters of activities, which the service flagged as suspicious, around OpenAI-themed events since March 2023. Unusual Whales flagged 77 positions in 60 wallet addresses as suspected insider trades, looking at the age of the account, trading history, and significance of investment, among other factors. Suspicious trades hinged on the release dates of products like Sora, GPT-5, and the ChatGPT Browser, as well as CEO Sam Altman's employment status. In November 2023, two days after Altman was dramatically ousted from the company, a new wallet placed a significant bet that he would return, netting over $16,000 in profits. The account never placed another bet. The behavior fits into patterns typical of insider trades. "The tell is the clustering. In the 40 hours before OpenAI launched its browser, 13 brand-new wallets with zero trading history appeared on the site for the first time to collectively bet $309,486 on the right outcome," says Unusual Whales CEO Matt Saincome. "When you see that many fresh wallets making the same bet at the same time, it raises a real question about whether the secret is getting out." [...] Though this is the first confirmed case of a large technology company firing an employee over trades in prediction markets, it's almost certainly not the last. Opportunities for tech sector employees to make trades on markets abound. "The data tells me this is happening all over the place," Saincome says.

Researchers at Cortical Labs used living human neurons grown on a chip to learn how to play Doom in about a week. "While its performance is not up to par with humans, experts say it brings biological computers a step closer to useful real-world applications, like controlling robot arms," reports New Scientist. From the report: In 2021, the Australian company Cortical Labs used its neuron-powered computer chips to play Pong. The chips consisted of clumps of more than 800,000 living brain cells grown on top of microelectrode arrays that can both send and receive electrical signals. Researchers had to carefully train the chips to control the paddles on either side of the screen. Now, Cortical Labs has developed an interface that makes it easier to program these chips using the popular programming language Python. An independent developer, Sean Cole, then used Python to teach the chips to play Doom, which he did in around a week. "Unlike the Pong work that we did a few years ago, which represented years of painstaking scientific effort, this demonstration has been done in a matter of days by someone who previously had relatively little expertise working directly with biology," says Brett Kagan of Cortical Labs. "It's this accessibility and this flexibility that makes it truly exciting." The neuronal computer chip, which used about a quarter as many neurons as the Pong demonstration, played Doom better than a randomly firing player, but far below the performance of the best human players. However, it learnt much faster than traditional, silicon-based machine learning systems and should be able to improve its performance with newer learning algorithms, says Kagan. However, it's not useful to compare the chips with human brains, he says. "Yes, it's alive, and yes, it's biological, but really what it is being used as is a material that can process information in very special ways that we can't recreate in silicon." Cortical Labs posted a YouTube video showing its CL1 biological computer running Doom. There's also source code available on GitHub, with additional details in a README file.

Author Dan Simmons, best known for the epic sci-fi novel Hyperion and its sequels, has died at 77 following a stroke. Ars Technica's Eric Berger remembers Simmons, writing: Simmons, who worked in elementary education before becoming an author in the 1980s, produced a broad portfolio of writing that spanned several genres, including horror fiction, historical fiction, and science fiction. Often, his books included elements of all of these. This obituary will focus on what is generally considered his greatest work, and what I believe is possibly the greatest science fiction novel of all time, Hyperion. Published in 1989, Hyperion is set in a far-flung future in which human settlement spans hundreds of planets. The novel feels both familiar, in that its structure follows Chaucer's Canterbury Tales, and utterly unfamiliar in its strange, far-flung setting. Simmons' Hyperion appeared in an Ask Slashdot story back in 2008, when Slashdot reader willyhill asked for tips on how Slashdotters track down great sci-fi. If you're in the mood for a little nostalgia, or just want to browse the thread for book recommendations, it's well worth revisiting.

The file system of the Windows operating system is NTFS, whether you're running it on a desktop/laptop or server. It's the only file system Windows can run on and boot from, at least officially, so you're not even given a choice of file systems for the boot volume like you are on, say, desktop Linux. That's about to change, though: Microsoft has finally announced that Windows Server will be able to boot from ReFS. We're excited to announce that Resilient File System (ReFS) boot support is now available for Windows Server Insiders in Insider Preview builds. For the first time, you can install and boot Windows Server on an ReFS-formatted boot volume directly through the setup UI. With ReFS boot, you can finally bring modern resilience, scalability, and performance to your server's most critical volume - the OS boot volume. ↫ chcurlet-msft at Microsoft's Tech Community Without diving too much into the weeds, ReFS can roughly be seen as Microsoft's answer to modern file systems like ZFS and Btrfs, with comparable design goals and feature sets. It's been around since 2012, but only for Windows Server, and with every Windows Server release since, the company has improved performance, added new features, and fixed bugs. Now, in 2026, it seems Microsoft thinks ReFS is ready to be used as a bootable file system for Windows Server. If you want to try this for yourself, you need to be a Windows Insider and make sure you have Windows Server build 29531.1000.260206-1841 or newer. During installation, the Windows installer will ask you to choose between NTFS and ReFS; the rest of the installation process will be pretty much the same as before. Now all we need is to wait for ReFS to become an option on client versions of Windows too, which would mark - arguably - only the second time in history Windows transitioned from one default filesystem to the another.

Encryption backdoors, social media bans for children, creepy age verification for applications - what will they think of next? The latest brilliant idea by US lawmakers sure is a hell of a doozy: legally mandated age verification in every single operating system. Colorado's SB26-051, introduced last month, would require operating systems to register the owner's age, which third-party apps can then leverage to determine if the user is an adult. The bill calls for the device owner to register their birthdate or age, but for the purposes of creating an "age bracket," which can then be shared to an app developer through an API to learn their age range, according to BiometricUpdate.com. Ball also said the legislation was based on California's bill AB 1043, which was passed last year. It too requires OS makers to create a way for the device owner to register their age bracket, which can then be shared to app developers over an API. The California law starts to take effect January 1, 2027. ↫ Michael Kan at PCMag Age verification to protect children sounds innocent enough, but if you have more than two brain cells to rub together it's crystal clear that what we're really looking at is the true end of privacy and online anonymity. If age verification is only used by certain applications, it's easy enough to avoid them, but if it becomes part of Windows, desktop Linux, Android, it's truly game over. Nobody will be anonymous online ever again, and nobody will have any sense of privacy left when opening up their computer. Worse yet, if you do end up using an operating system that doesn't adhere to this law, or you hack out or circumvent the age verification nonsense, you'll automatically become an easy target for law enforcement. Clearly, if you circumvent age verification, you must be up to no good, right? Of course, as we've seen in countries with heavily deteriorating democracies and freedoms, like the US or Hungary, even merely opposing the government will be classified as "up to no good", and let's not even get started about the various minorities these countries are actively trying to eradicate. If something like this is enshrined in law in your country, you're fucked.

FreeBSD has its jails technology, and it seems NetBSD might be getting something similar soon. Jails for NetBSD aims to bring lightweight, kernel-enforced isolation to NetBSD. The system is intended to remain fully NetBSD-native. Isolation and policy enforcement are integrated into the kernel's security framework rather than implemented in a separate runtime layer. It does not aim to become a container platform. It does not aim to provide virtualization. ↫ Matthias Petermann It has all the usual features you have come to expect from jails, like resource quota, security profiles, logging, and so on. Processes inside jails have no clue they're in a jail, and using supervisor mode, jails are descendent from a single process and remain visible in the host process table. Of course, there's many more features listed in the linked article. It's in development and not a default part of NetBSD at this time. The project, led by Matthias Petermann, is developed out of tree, with an unofficial NetBSD 10.1 ISO with the jails feature included available as well.

While starting this post I realized I have been maintaining personal infrastructure for over a decade! Most of the things I've self-hosted is been for personal uses. Email server, a blog, an IRC server, image hosting, RSS reader and so on. All of these things has all been a bit all over the place and never properly streamlined. Some has been in containers, some has just been flat files with a nginx service in front and some has been a random installed Debian package from somewhere I just forgot.
