  • Microsoft Accidentally Breaks Replying To an Email On Outlook
    by BeauHD on 22/06/2026 at 11:00 pm

    Microsoft has accidentally introduced a bug in Outlook for Mac that omits the original message from email replies, making it difficult for recipients to follow conversation history. Until Microsoft releases a fix, its suggested workaround is to roll back from version 16.110 and disable automatic updates, which is "great for users in full control of their devices -- not so good for anyone with a managed device," notes The Register. "Administrators with fleets of Macs running Outlook should brace for helpdesk tickets." From the report: In some instances, having a user copy and paste the salient bits of the email they are responding to might not be such a bad thing. We've all had emails that required epic amounts of scrolling to find what started the conversation, so forcing users to think about what they actually need to include is no bad thing. However, disrupting user workflows without warning -- well, that is undoubtedly a bad thing. This is, after all, one of the most basic things an email client needs to do, so shipping a product with a bug that breaks this functionality says more about Microsoft's approach to quality than anything else.

  • Following User Outcry, AMD Reinstates Memory Encryption In Consumer CPUs
    by BeauHD on 22/06/2026 at 10:00 pm

    Last week, AMD was found to have stripped memory encryption from its consumer CPUs without any warning or notice. Now, following a wave of backlash on social media, the chipmaker has now reinstated the protection, though it still hasn't explained why the safeguard was disabled in the first place. Ars Technica reports: Following the revelation, social media was deluged by comments from AMD consumers decrying the move. They noted that AMD's quiet removal of TSME after supporting it for so long seemed underhanded. The move came solely as a result of firmware changes made in a recent update. With no physical changes required to silicon, continued support was largely, if not purely, a matter of will rather than a necessity required by changes to hardware. The critics called on AMD to reverse the move. Over the weekend, AMD said it planned to do just that in a firmware update scheduled for release next month. More often than not, the chipmaker refers to TSME as Memory Guard. "Regarding certain non-PRO Ryzen 9000-series desktop processors, a BIOS option to enable Memory Guard was previously available but was removed in a recent update," AMD said in an email. "Based on valuable community feedback, we will reinstate this option in an upcoming BIOS release in July." The company has yet to explain why it removed the protection. Critics speculate that AMD dropped it in an attempt to steer customers toward more costly CPUs. It's possible, though, that there were less nefarious reasons, such as the difficulty of continued support as chip designs changed. Another possibility is that AMD made the move for performance reasons. Encrypting and decrypting data in memory creates latency. Slowdowns are the enemy of gamers, one of the more popular customer segments using the 9000-line of Ryzen processors. Since many gamers already voluntarily disabled TSME and had little need for it in the first place, AMD may not have considered the change of much consequence. Read more of this story at Slashdot.

  • Valve Will Finally Let You Build Your Own Steam Machine With SteamOS For Desktop
    by BeauHD on 22/06/2026 at 9:00 pm

    With the price of the new Steam Machine starting at $1,049, you might want to consider making your own Steam Machine instead. An anonymous reader quotes a report from The Verge: Valve says that "starting with the SteamOS 3.8 release, you can put together your own Steam Machine using whatever PC parts you want." SteamOS 3.8.10 launched last week with a slew of updates, including "improved compatibility with recent Intel and AMD platforms." Alongside that improved compatibility, Valve is giving gamers the green light to install SteamOS on their own desktops. In an interview with The Verge, Valve's Pierre-Loup Griffais said Valve has been "rolling out improvements to [SteamOS] so it's more compatible with desktop hardware," including eventual support for Nvidia graphics. Griffais says Valve has "a growing team" working on Nvidia driver support for SteamOS, adding, "We're collaborating with Nvidia very closely." While he mentioned that Nvidia support might not come this year, Griffais emphasized that "it's certainly something that we're working on in the background." It's technically been possible to run SteamOS on your own hardware for a while now, but compatibility has been mostly limited to AMD systems. So far installing it has also required using a Steam Deck recovery image, a process that, speaking from experience, is much less straightforward than the installation process for most other Linux distributions. Trying to run SteamOS on Intel or Nvidia hardware has not been easy so far. According to Griffais, Valve is working to change that, which could mean that down the line, you'll be able to run SteamOS on just about any gaming PC hardware you want, including Nvidia. For the more immediate future, Griffais says SteamOS in its current state should offer a "good experience" on console-like PC setups: "If you have something that is similar to the use case of a Steam Machine, where you have a PC that's gonna be plugged into a TV, and has a single hard drive that you're not going to try and dual boot [] you can put SteamOS on there, and you'll have an experience that is very similar to a Steam Deck docked or a Steam Machine, with some caveats, of course," like a lack of HDMI-CEC support. But "the core bits of the experience are there. The SteamOS graphics driver, the shader precompilation [...] you can get at all of that with the SteamOS." Griffais says SteamOS does not yet offer an easy way to dual-boot alongside Windows or another operating system, but envisions "a time where it's a better experience to install on your desktop and have it coexist with a different operating system."

  • Google Invests $75 Million In A24 To Develop AI-Powered Filmmaking Tools
    by BeauHD on 22/06/2026 at 8:00 pm

    Google is investing roughly $75 million in A24 as part of a research partnership with DeepMind to develop AI-powered filmmaking tools and workflows. "The deal represents the latest marriage between a Hollywood studio and AI in an era where companies have oscillated between partnerships and lawsuits," reports Variety. From the report: A24 partner Scott Belsky, who leads the studio's technology division A24 Labs, told the Journal the studio's Google partnership differed from other deals because AI developers mistakenly advertised their products as a means to make films cheaper and faster. His division is developing applications for AI-generated storyboards, another reimagination of the production process that has seen filmmakers like Martin Scorsese rubber-stamp. "We think there are better uses that preserve creative control and support risk-taking," said Belsky, arguing the new tools "won't look anything like the prompted generation type of AI that people feel uncomfortable with."

  • Some Electricians Think Building Data Centers Is For Sellouts
    by BeauHD on 22/06/2026 at 7:00 pm

    An anonymous reader quotes a report from Wired: As Big Tech dumps billions of dollars into America's data center buildout, a slew of opportunities have opened up to the electricians wiring these massive facilities. In some cases, the scale of the projects and the demanding construction timelines are fueling talent wars for the industry's best and brightest. The US-based International Brotherhood of Electrical Workers (IBEW) has argued that its workers are "powering the AI Revolution," and a set of "Data Center Principles" published in March argues that union labor is "essential to the future of AI." Tech companies are trying to meet the moment: Meta recently announced a skilled trade academy program, and Google committed $50 million to help train people in skilled trades. But amid growing national opposition to data centers, debates over the ethics of the massive buildout have started to pop up in some online pockets of the community. Threads about how AI will affect the economy now pepper r/electricians, a subreddit with around half a million monthly visitors. Some users wonder whether the work will eventually prompt widespread job losses. Others aren't sure if their labor makes them complicit in the damage done to local communities or whether it's unethical to take on data center work. For some, the answer is a firm no. Ultimately, they argue, work is work. An anonymous Midwest electrician who spoke to Wired acknowledged concerns about scams, corporate greed, and AI's impact on workers, but said he views data centers as an important source of career advancement. "This is most likely going to be a major part of our future. And if you can't beat them, join them," he said. An electrician named Ryan, meanwhile, is strongly opposed to working on data centers because he distrusts the corporations and political environment driving AI development. Still, if the facilities are going to be built, he would prefer union workers construct them. "If they're going to get built, I'd rather they go union," he said. Jesse, an IBEW electrician, sympathizes with communities negatively affected by data centers but does not believe the electricians building them should be blamed. In his view, opposition should instead be directed toward policymakers and the project approval process. "I think it's ridiculous if, to build a data center or any kind of a business, you're going to significantly impact the lives of that community in a negative way," he told Wired. An electrician named Dante echoed some of those sentiments, arguing that data center work is no more ethically compromised than many other commercial construction projects. "We're almost always working for the worst possible people in the end, but we all need a paycheck," he said. He added that such projects are "essentially the same kind of work," typically performed for wealthy corporations seeking to become even richer. Read more of this story at Slashdot.

  • Valve Prices the Steam Machine At $1,049
    by BeauHD on 22/06/2026 at 6:00 pm

    Valve's new Steam Machine will launch June 29 starting at $1,049 and go up from there depending on the configuration. Although it costs considerably more than the PS5 ($599.99) and Xbox Series X ($649.99), "the value proposition for the Steam Machine is that it can play your library of Steam games you may have accumulated over years (or even decades), rather than just PlayStation games, and it's also a full Linux PC that you can customize to your heart's content," reports The Verge. "Valve also says that it's selling the Steam Machine for the cost of its components alone instead of subsidizing the price." From the report: You can now register your interest to buy a Steam Machine as part of a reservation system. To offer a fair playing field for people who want to buy one, Valve will randomize everyone in the queue on Thursday at 1PM ET. After that, anyone who registers their interest will be added to the end of the waitlist. The first emails giving people the opportunity to buy will go out on June 29th. Valve will sell four configurations of the Steam Machine: - A 512GB model for $1,049 - A 512GB model with a bundled Steam Controller for $1,128 - A 2TB model for $1,349 - A 2TB model with a bundled Steam Controller for $1,428 Read more of this story at Slashdot.
