Valve has released CAD files for the new Steam Controller and its Puck under a Creative Commons license. "The idea is to let enterprising modders create their own Steam Controller add-ons, like skins, charging stands, grip extenders or smartphone mounts," reports Digital Foundry. From the report: The Valve release includes files for the external shell ("surface topology") of the Controller and Puck, with a .STP, .STL and engineering diagram of each device, with the latter showing areas that must remain uncovered to let the device maintain its signal strength and otherwise function as designed. Valve has previously released CAD files for its Steam Deck handheld, Valve Index VR suite and even the original Steam Controller a decade ago, so this release is welcomed but not unexpected.

The release is under a fairly restrictive Creative Commons license which allows for non-commercial use and requires attribution and sharing of designs back to the community. However, the license also suggests that commercial entities interested in making accessories for the Steam Controller or its Puck can contact Valve directly to discuss terms. You can find the files here.

Steam on Linux use in March "had skyrocketed to 5.33%..." reports Phoronix, "easily the highest level we've seen Steam on Linux at since its inception more than a decade ago."

So what happened in April? [April's results] point to Linux having a 4.52% marketshare on Steam, a drop of 0.81% compared to March. Year-over-year it's roughly double with Steam on Linux in April 2025 being at 2.27%. Or two years ago for April 2024, Steam on Linux was at 1.9%.

Microsoft released the "Windows Subsystem for Linux" in 2016, adding an optional Linux environment into every operating system since Windows 10. But now an open source developer has brought Linux to Windows 95, Windows 98, and Windows Me, reports the blog It's FOSS, "with Linux kernel 6.19 running alongside the Windows 9x kernel, letting both operate on the same machine at the same time." A virtual device driver handles initialization, loads the kernel off disk and manages the event loop for page faults and syscalls. Since Win9x lacks the right interrupt table support for the standard Linux syscall interrupt, WSL9x reroutes those calls through the fault handler instead. Rounding it all out is wsl.com, a small 16-bit DOS program that pipes the terminal output from Linux back to whatever MS-DOS prompt window you ran it from.
The end result is that WSL9x requires no hardware virtualization, and can run on hardware as old as the i486, the article points out. On Mastodon the developer says they "really got this one in right under the wire, before they start removing 486 support from Linux."

The source code for WSL9x is released under the GPL-3 license, and was "proudly written without AI."

"After a Supreme Court of the United States ruling in Feb. 2026, many tariffs imposed by the Trump administration were declared illegal because the president overstepped his authority," writes Slashdot reader hcs_$reboot. "As a result, the U.S. government now has to refund a massive amount of money, around $160-170+ billion, paid mainly by importers." According to the New York Times, the administration has now begun accepting refund requests, "surrendering its prized source of revenue -- plus interest." From the report: For some U.S. businesses, the highly anticipated refunds could be substantial, offering critical if belated financial relief. Tariffs are taxes on imports, so the president's trade policies have served as a great burden for companies that rely on foreign goods. Many have had to choose whether to absorb the duties, cut other costs or pass on the expenses to consumers. By Monday morning, those companies can begin to submit documentation to the government to recover what they paid in illegal tariffs.

In a sign of the demand, more than 3,000 businesses, including FedEx and Costco, have already sued the Trump administration in a bid to secure their refunds, with some cases filed even before the Supreme Court's ruling. But only the entities that officially paid the tariffs are eligible to recover that money. That means that the fuller universe of people affected by Mr. Trump's policies -- including millions of Americans who paid higher prices for the products they bought -- are not able to apply for direct relief.

The extent to which consumers realize any gain hinges on whether businesses share the proceeds, something that few have publicly committed to do. Some have started to band together in class-action lawsuits in the hopes of receiving a payout. Many business owners said they weren't sure how easy the tariff refund process would be, particularly given Mr. Trump's stated opposition to returning the money. The administration has suggested that it may be months before companies see any money. Adding to the uncertainty, the White House has declined to say if it might still try to return to court in a bid to halt some or all of the refunds. The money will mostly go to importers and companies, since they were the ones that directly paid the tariffs. While individual refunds with interest could take around 60 to 90 days to process, the overall effort will probably move much more slowly because of how large and complicated it will be.

There are also legal questions around whether companies would have to pass any of that money on to consumers. Slashdot reader AmiMoJo commented: "This is perhaps the biggest transfer of wealth in American history. Most of those companies will just pocket the refund and not pass any of it on to the consumer. If prices go down at all, they won't be back to pre-tariff levels. You paid the tariffs, but you ain't getting the refund."

The Brave browser "has introduced Brave Origin, a stripped-down version of its browser that removes built-in monetization features like Rewards and other extras tied to its business model," writes Slashdot reader BrianFagioli" The stripped-down browser is available either as a separate browser download or as an upgrade to the existing Brave install, unlocked through a one-time purchase that can be activated across multiple devices. The idea is simple on paper: pay once, and you get a cleaner, more minimal browsing experience without the add-ons that fund Brave's ecosystem. What makes the move unusual is the pricing model itself. While paying to support a browser is not controversial, charging users specifically to remove features raises questions about whether those additions are seen as value or clutter.

The situation gets even stranger on Linux, where Brave Origin is reportedly available at no cost, creating an uneven experience across platforms and leaving some users wondering why they are being asked to pay for something others get for free.
