The June Steam Survey results show that AMD CPUs have gained significant popularity among Linux gamers, with a market share of 67% -- a remarkable 7% increase from the previous month. Phoronix reports: In part that's due to the Steam Deck being powered by an AMD SoC but it's been a trend building for some time of AMD's increasing Ryzen CPU popularity among Linux users to their open-source driver work and continuing to build more good will with the community.

In comparison, last June the AMD CPU Linux gaming marketshare came in at 45% while Intel was at 54%. Or at the start of 2023, AMD CPUs were at a 55% marketshare among Linux gamers. Or if going back six years, AMD CPU use among Linux gamers was a mere 18% during the early Ryzen days. It's also the direct opposite on the Windows side. When looking at the Steam Survey results for June limited to Windows, there Intel has a 68% marketshare to AMD at 32%.

Beyond the Steam Deck, it's looking like AMD's efforts around open-source drivers, AMD expanding their Linux client (Ryzen) development efforts over the past two years, promises around OpenSIL, and other efforts commonly covered on Phoronix are paying off for AMD in wooing over their Linux gaming customer base.

Kentucky is requiring that electric vehicle charging companies include Tesla's plug if they want to be part of a state program to electrify highways using federal dollars, according to documents reviewed by Reuters. From the report: Kentucky's plan went into effect on Friday, making it the first state to mandate Tesla's charging technology, although Texas and Washington states previously shared such plans with Reuters. In addition to federal requirements for the rival Combined Charging System (CCS), Kentucky mandates Tesla's plug, called the North American Charging Standard (NACS), at charging stations, according to Kentucky's request for proposal (RFP) for the state's EV charging program on Friday.

"Each port must be equipped with an SAE CCS 1 connector. Each port shall also be capable of connecting to and charging vehicles equipped with charging ports compliant with the North American Charging Standard (NACS)," the documents say. The U.S. Department of Transportation earlier this year said that charging companies must provide CCS plugs to be eligible for federal funding to deploy 500,000 EV chargers by 2030. It added that the rule allows charging stations to have other connectors, as long as they support CCS, a national standard.

An anonymous reader writes: The Federal Aviation Administration has certified for testing a vehicle that a California startup describes as a flying car -- the first fully electric vehicle that can both fly and travel on roads to receive US government approval. Alef Automotive said that its vehicle/aircraft, dubbed the "Model A," is the first flying vehicle that is drivable on public roads and able to park like a normal car. It also has vertical takeoff and landing capabilities. It apparently will be able to carry one or two occupants and will have a road-range of 200 miles and a flying range of 110 miles.

The company expects to sell the vehicle for $300,000 each with the first delivery by projected for the end of 2025. The FAA confirmed that it has issued the company a special airworthiness certificate, allowing for limited purposes that include exhibition, research and development. Numerous companies are working on all-electric VTOLs, which stands for vehicle takeoff and landing aircraft. The FAA said that Alef is "not the first aircraft of its kind" to get a special airworthiness certificate. However, Alef noted that its vehicle is different because of its ability to function both on roads and in the air, to appear like a normal car and to park in a normal parking space.

Reactions continue to Red Hat's announcement that they'd start limiting access to Red Hat Enterprise Linux sources, reports Ars Technica: Rocky Linux, launched by CentOS co-founder Greg Kurtzer as a replacement RHEL-compatible distro, announced Thursday that it believes Red Hat's moves "violate the spirit and purpose of open source." Using a few different methods (Universal Base Image containers, pay-per-use public cloud instances), Rocky Linux intends to maintain what it considers legitimate access to RHEL code under the GNU General Public License (GPL) and make the code public as soon as it exists.
"These methods are possible because of the power of GPL," explains Rocky Linux's blog post. "No one can prevent redistribution of GPL software. To reiterate, both of these methods enable us to legitimately obtain RHEL binaries and SRPMs without compromising our commitment to open source software or agreeing to TOS or EULA limitations that impede our rights. Our legal advisors have reassured us that we have the right to obtain the source to any binaries we receive, ensuring that we can continue advancing Rocky Linux in line with our original intentions.... [O]ur unwavering dedication and commitment to open source and the Enterprise Linux community remain steadfast."

"In the unfortunate event that Red Hat decides to ramp up efforts to negatively impact the community, Rocky Linux will persist to continue serving the best interests of the entire open source community. As a reminder, we welcome everyone to contribute to our efforts. You can learn more about how you can join us and all of the various ways to contribute on our wiki."

Ars Technica notes that AlmaLinux is "also working to keep providing RHEL-compatible updates and downstream rebuilds." "The process is more labor intensive as we require gathering data and patches from several sources, comparing them, testing them, and then building them for release," wrote Jack Aboutboul, community manager for AlmaLinux, in a blog post. "But rest assured, updates will continue flowing just as they have been."

The Software Freedom Conservancy's Bradley M. Kuhn weighed in last week with a comprehensive overview of RHEL's business model and its tricky relationship with GPL compliance. Red Hat's business model "skirts" GPL violation but had only twice previously violated the GPL in newsworthy ways, Kuhn wrote. Withholding Complete Corresponding Source (CCS) from the open web doesn't violate the GPL itself, but by doing so, Red Hat makes it more difficult for anyone to verify the company's GPL compliance.

Kuhn expressed sadness that "this long road has led the FOSS community to such a disappointing place."
Red Hat argued that they "do not find value in a RHEL rebuild." Rocky Linux dismissed this view as "narrow-minded," and RHEL-derived AlmaLinux even responded with specific examples, also noting its contributions to the RHEL and CentOS communities. AlmaLinux's community manager wrote "When executed properly, downstream rebuilds provide tremendous value and are a tremendous asset to upstream projects."

And ITWire shares one more reaction: German open source vendor SUSE says it will not be making any changes to its policies on source code access, emphasising "that the freedom to access, modify, and distribute software should remain open to all".

A new article in the Washington Post reports that even internally, "Space Force officials are still debating its priorities, analysts say: Is it to support warfighters on the ground? Or should it focus primarily on protecting assets in space? Or both?"

In April, the Washington Post reported that space would likely be a key part of a Chinese invasion of Taiwan, and one possible Space Force counter-measure would "ensure that the United States avoids 'operational surprise,' by keeping track of other countries' satellites and movements in space while also being able to 'identify behaviors that become irresponsible or even hostile.'"

To address the possibility of enemies shooting down satellites, the Space Force is also "pivoting, relying on constellations of small satellites that can be easily replaced and, to an increasing degree, maneuver." That's just one example of how the Space Force intends to ensure the U.S. maintains "space superiority," as its leaders often say, to protect the satellites the Defense Department relies on for warnings of incoming missiles, steering precision-guided munitions and surveilling both friendly and hostile forces. It also could deter conflict in space — why strike a satellite if there are backups that would easily carry on the mission...?

[Maj. Gen. Stephen Purdy, the commander of the 45th Space Wing] gave a tour of some of the roles the Space Force could play, offering a glimpse into its future. Soldiers and Marines already pre-position supplies and equipment on the ground, he said. Could the Space Force start storing supplies in space and then fly them to hot spots on Earth as well? "In theory, we could have huge racks of stuff in orbit and then somebody can call those in, saying. 'I need X, Y, Z delivered to me now on this random island.' And then, boom, they shoot out and they parachute in and they land with GPS assistance," he said. "It's a fascinating thought exercise for emergency response — you know if a type of tidal wave or tsunami comes in and wipes out a whole area."

The military is also working to harness solar energy in space, and then beam it to ground stations. Could the Space Force use that technology to beam power to remote areas to support soldiers on the ground? Another idea: If the cadence of launches really does double or triple and the costs continue to come down, could the Space Force start using rockets to deliver cargo across the globe at a moment's notice? Soon there could be commercial space stations floating around in orbit. "Can we lease a room?" Purdy said. "Can we lease a module?"
A former vice chairman of the Joint Chiefs of Staff believes the U.S. Space Force is misunderstood — at least partly because much of what it does is classified. "We fundamentally need to normalize the classification," he tells the Washington Post, "so we can have a conversation with the public, with the American people."
