China "accounts for more than half of global coal use," reports Asia Times, "even as it builds the world's largest solar-panel and EV industries."
Much of the world's solar gear is made on fossil power. The International Energy Agency finds that "coal generates over 60% of the electricity used for global solar PV manufacturing," far above coal's ~36% share of typical grids. That is because over 80% of PV factories sit in Chinese provinces like Xinjiang and Jiangsu, where coal dominates the grid.

China has poured over $50 billion into solar factories since 2011, roughly ten times Europe's investment, cutting panel costs by about 80% and fueling a worldwide solar boom. But those panels were produced on coal. In one analysis, they repay their manufacturing CO2 in only months, meaning the emissions were dumped up-front in China's coal plants. Any major disruption to China's coal power or factories (from grid shocks to trade barriers) could thus send ripples through the global PV market.
China's coal and heavy industries also feed its clean-tech supply chain. Coal-fired steel mills supply the aluminum and metal parts for EVs and panels, and coal chemicals provide battery precursors and silicon for solar... At the same time, Chinese oil and gas giants (CNPC, Sinopec) have set up solar, wind and battery divisions, redirecting fossil profits into green ventures.
Another interesting statistic from the article: "In Thailand, Asia's long-time auto hub, Chinese EV brands now command more than 70% of EV sales."

"Microsoft's Outlook email service malfunctioned for over 21 hours Wednesday and Thursday," reports CNBC, "prompting some people to post on social media about the inability to reach their virtual mailboxes."
The issue began at 6:20 p.m. Eastern time on Wednesday, according to a dashboard the software company maintains. It affected Outlook.com as well as Outlook mobile apps and desktop programs. At 12:21 ET on Thursday, the Microsoft 365 Status account posted that it was rolling out a fix.
Although earlier on Thursday Microsoft posted on X that "We identified an issue with the initial fix, and we've corrected it..."

More details from the Associated Press:

Disruptions appeared to peak just before noon ET on Thursday, when more than 2,700 users worldwide reported issues with Outlook, formerly also Hotmail, to outage tracker Downdetector. Some said they encountered problems like loading their inboxes or signing in. By later in the afternoon, reports had fallen to just over a couple hundred...
Microsoft did not immediately provide more information about what had caused the hourslong outage. A spokesperson for Microsoft had no further comment when reached by The Associated Press on Thursday.

It killed tens of millions of people in 14th century Europe," CNN reports, though "today, it's easily treated with antibiotics."

And yet "A resident of northern Arizona has died from pneumonic plague, health officials said Friday."

Plague is rare to humans, with on average about seven cases reported annually in the U.S., most of them in the western states, according to federal health officials. The death in Coconino County, which includes Flagstaff, was the first recorded death from pneumonic plague since 2007, local officials said... The bubonic plague is the most common form of the bacterial infection, which spreads naturally among rodents like prairie dogs and rats. There are two other forms: septicemic plague that spreads through the whole body, and pneumonic plague that infects the lungs. Pneumonic plague is the most deadly and easiest to spread.

[>] Robinhood Up 160% in 2025, But May Face Obstacles

Robinhood's stock hit is up more than 160% for 2025, reports CNBC, and the trading platform's own stock hit an all-time high on Friday. But "Despite its stellar year, the online broker is facing several headwinds..."

Florida Attorney General James Uthmeier opened a formal investigation into Robinhood Crypto on Thursday, alleging the platform misled users by claiming to offer the lowest-cost crypto trading. "Robinhood has long claimed to be the best bargain, but we believe those representations were deceptive," Uthmeier said in a statement. The probe centers on Robinhood's use of payment for order flow — a common practice where market makers pay to execute trades — which the AG said can result in worse pricing for customers.

Robinhood is also facing opposition to a new 25% cut of staking rewards for U.S. users, set to begin October 1. In Europe, the platform will take a smaller 15% cut. Staking allows crypto holders to earn yield by locking up their tokens to help secure blockchain networks like ethereum, but platforms often take a percentage of those rewards as commission. Robinhood's 25% cut puts it in line with Coinbase, which charges between 25.25% and 35% depending on the token. The cut is notably higher than Gemini's flat 15% fee. It marks a shift for the company, which had previously steered clear of staking amid regulatory uncertainty...

The company now offers blockchain-based assets in Europe that give users synthetic exposure to private firms like OpenAI and SpaceX through special purpose vehicles, or SPVs. An SPV is a separate entity that acquires shares in a company. Users then buy tokens of the SPV and don't have shareholder privileges or voting rights directly in the company. OpenAI has publicly objected, warning the tokens do not represent real equity and were issued without its approval... "What's important is that retail customers have an opportunity to get exposure to this asset," [Robinhood CEO Vlad Tenev said in an interview with CNBC], pointing to the disruptive nature of AI and the historically limited access to pre-IPO companies. "It is true that these are not technically equity," Tenev added, noting that institutional investors often gain similar exposure through structured financial instruments...

Despite the regulatory noise, many investors remain focused on Robinhood's upside, and particularly the political tailwinds.

[>] NVIDIA Warns Its High-End GPUs May Be Vulnerable to Rowhammer Attacks

Slashdot reader BrianFagioli shared this report from Nerds.xyz:

NVIDIA just put out a new security notice, and if you're running one of its powerful GPUs, you might want to pay attention. Researchers from the University of Toronto have shown that Rowhammer attacks, which are already known to affect regular DRAM, can now target GDDR6 memory on NVIDIA's high-end GPUs when ECC [error correction code] is not enabled.

They pulled this off using an A6000 card, and it worked because system-level ECC was turned off. Once it was switched on, the attack no longer worked. That tells you everything you need to know. ECC matters.

Rowhammer has been around for years. It's one of those weird memory bugs where repeatedly accessing one row in RAM can cause bits to flip in another row. Until now, this was mostly a CPU memory problem. But this research shows it can also be a GPU problem, and that should make data center admins and workstation users pause for a second.

NVIDIA is not sounding an alarm so much as reminding everyone that protections are already in place, but only if you're using the hardware properly. The company recommends enabling ECC if your GPU supports it. That includes cards in the Blackwell, Hopper, Ada, and Ampere lines, along with others used in DGX, HGX, and Jetson systems. It also includes popular workstation cards like the RTX A6000.

There's also built-in On-Die ECC in certain newer memory types like GDDR7 and HBM3. If you're lucky enough to be using a card that has it, you're automatically protected to some extent, because OD-ECC can't be turned off. It's always working in the background. But let's be real. A lot of people skip ECC because it can impact performance or because they're running a setup that doesn't make it obvious whether ECC is on or off. If you're not sure where you stand, it's time to check. NVIDIA suggests using tools like nvidia-smi or, if you're in a managed enterprise setup, working with your system's BMC or Redfish APIs to verify settings.

[>] 'Firefox is Fine. The People Running It are Not'

"Firefox is dead to me," wrote Steven J. Vaughan-Nichols last month for The Register, complaining about everything from layoffs at Mozilla to Firefox's discontinuation of Pocket and Fakespot, its small market share, and some user complaints that the browser might be becoming slower. But a new rebuttal (also published by The Register) argues instead that Mozilla just has "a management layer that doesn't appear to understand what works for its product nor which parts of it matter most to users..."

"Steven's core point is correct. Firefox is in a bit of a mess — but, seriously, not such a bad mess. You're still better off with it — or one of its forks, because this is FOSS — than pretty much any of the alternatives."
Like many things, unfortunately, much of computing is run on feelings, tradition, and group loyalties, when it should use facts, evidence, and hard numbers. Don't bother saying Firefox is getting slower. It's not. It's faster than it has been in years. Phoronix, the go-to site for benchmarks on FOSS stuff, just benchmarked 21 versions, and from late 2023 to now, Firefox has steadily got faster and faster...

Ever since Firefox 1.0 in 2004, Firefox has never had to compete. It's been attached like a mosquito to an artery to the Google cash firehose... Mozilla's leadership is directionless and flailing because it's never had to do, or be, anything else. It's never needed to know how to make a profit, because it never had to make a profit. It's no wonder it has no real direction or vision or clue: it never needed them. It's role-playing being a business. Like we said, don't blame the app. You're still better off with Firefox or a fork such as Waterfox. Chrome even snoops on you when in incognito mode...
One observer has been spectating and commentating on Mozilla since before it was a foundation — one of its original co-developers, Jamie Zawinksi... Zawinski has repeatedly said: "Now hear me out, but What If...? browser development was in the hands of some kind of nonprofit organization?"

"In my humble but correct opinion, Mozilla should be doing two things and two things only:

— Building THE reference implementation web browser, and
— Being a jugular-snapping attack dog on standards committees.
— There is no 3."

Perhaps this is the only viable resolution. Mozilla, for all its many failings, has invented a lot of amazing tech, from Rust to Servo to the leading budget phone OS. It shouldn't be trying to capitalize on this stuff. Maybe encourage it to have semi-independent spinoffs, such as Thunderbird, and as KaiOS ought to be, and as Rust could have been. But Zawinski has the only clear vision and solution we've seen yet. Perhaps he's right, and Mozilla should be a nonprofit, working to fund the one independent, non-vendor-driven, standards-compliant browser engine.
