    End of Windows 10 Leaves PC Charities With Tough Choice
    With Microsoft ending free security updates for Windows 10 in October, millions of PCs that don't meet Windows 11's hardware requirements face an uncertain fate... Charities that refurbish and distribute computers to low-income individuals must choose between providing soon-to-be-insecure Windows 10 machines, transitioning to Linux -- despite usability challenges for non-tech-savvy users -- or recycling the hardware, contributing to ewaste. Tom's Hardware reports: So how bad will it really be to run an end-of-lifed Windows 10? Should people worry? [Chester Wisniewski, who serves as Director and Global Field CISO for Sophos, a major security services company] and other experts I talked to are unequivocal. You're at risk. "To put this in perspective, today [the day we talked] was Patch Tuesday," he said. "There were 57 vulnerabilities, 6 of which have already been abused by criminals before the fixes were available. There were also 57 in February and 159 in January. Windows 10 and Windows 11 largely have a shared codebase, meaning most, if not all, vulnerabilities each month are exploitable on both OSs. These will be actively turned into digital weapons by criminals and nation-states alike and Windows 10 users will be somewhat defenseless against them." So, in short, even though Windows 10 has been around since 2015, there are still massive security holes being patched. Even within the past few weeks, dozens of vulnerabilities were fixed by Microsoft. So what's a charity to do when these updates are running out and clients will be left vulnerable? "What we decided to do is one year ahead of the cutoff, we discontinued Windows 10," said Casey Sorensen, CEO of PCs for People, one of the U.S.'s largest non-profit computer refurbishers. "We will distribute Linux laptops that are 6th or 7th gen. If we distribute a Windows laptop, it will be 8th gen or newer." Sorensen said that any PC that's fifth gen or older will be sent to an ewaste recycler. [...] Sorensen, who founded the company in 1998, told us that he's comfortable giving clients computers that run Linux Mint, a free OS that's based on Ubuntu. The latest version of Mint, version 22.1, will be supported until 2029. "Ten years ago if we distributed Linux, they would be like what is it," he said. But today, he notes that many view their computers as windows to the Internet and, for that, a user-friendly version of Linux is acceptable. Further reading: Is 2025 the Year of the Linux Desktop?

    Super Nintendo Hardware Is Running Faster As It Ages
    An anonymous reader quotes a report from 404 Media: Something very strange is happening inside Super Nintendo (SNES) consoles as they age: a component you've probably never heard of is running ever so slightly faster as we get further and further away from the time the consoles first hit the market in the early '90s. The discovery started a mild panic in the speedrunning community in late February since one theoretical consequence of a faster-running console is that it could impact how fast games are running and therefore how long they take to complete. This could potentially wreak havoc on decades of speedrunning leaderboards and make tracking the fastest times in the speedrunning scene much more difficult, but that outcome now seems very unlikely. However, the obscure discovery does highlight the fact that old consoles' performance is not frozen at the time of their release date, and that they are made of sensitive components that can age and degrade, or even 'upgrade', over time. The idea that SNESs are running faster in a way that could impact speedrunning started with a Bluesky post from Alan Cecil, known online as dwangoAC and the administrator of TASBot (short for tool-assisted speedrun robot), a robot that's programmed to play games faster and better than a human ever could. [...] So what's going on here? The SNES has an audio processing unit (APU) called the SPC700, a coprocessor made by Sony for Nintendo. Documentation given to game developers at the time the SNES was released says that the SPC700 should have a digital signal processing (DSP) rate of 32,000hz, which is set by a ceramic resonator that runs 24.576Mhz on that coprocessor. We're getting pretty technical here as you can see, but basically the composition of this ceramic component and how it resonates when connected to an electronic circuit generates the frequency for the audio processing unit, or how much data it processes in a second. It's well documented that these types of ceramic resonators are sensitive and can run at higher frequencies when subject to heat and other external conditions. For example, the chart [here], taken from an application manual for Murata ceramic resonators, shows changes in the resonators' oscillation under different physical conditions. As Cecil told me, as early as 2007 people making SNES emulators noticed that, despite documentation by Nintendo that the SPC700 should run at 32,000Hz, some SNESs ran faster. Emulators generally now emulate at the slightly higher frequency of 32,040Hz in order to emulate games more faithfully. Digging through forum posts in the SNES homebrew and emulation communities, Cecil started to put a pattern together: the SPC700 ran faster whenever it was measured further away from the SNES's release. Data Cecil collected since his Bluesky post, which now includes more than 140 responses, also shows that the SPC700 is running faster. There is still a lot of variation, in theory depending on how much an SNES was used, but overall the trend is clear: SNESs are running faster as they age, and the fastest SPC700 ran at 32,182Hz. More research shared by another user in the TASBot Discord has even more detailed technical analysis which appears to support those findings. "We don't yet know how much of an impact it will have on a long speedrun," Cecil told 404 Media. "We only know it has at least some impact on how quickly data can be transferred between the CPU and the APU." Cecil said minor differences in SNES hardware may not affect human speedrunners but could impact TASBot's frame-precise runs, where inputs need to be precise down to the frame, or "deterministic."

    Coal-Powered Energy Finally Overtaken by Wind and Solar in the US
    "Wind and solar energy generated more electricity in the U.S. than coal for the first time last year," reports the Wall Street Journal, "according to analysis from clean-energy think tank Ember. "The two renewable energy sources accounted for 17% of the country's power mix while coal fell to a low of 15%, it said." Solar was the fastest-growing energy source, according to Ember's analysis of data from the U.S. Energy Information Administration, increasing 27% from the year before, while wind rose 7%... Natural gas generation increased 3.3% in 2024, according to Ember, and remains by far the largest source of electricity in the U.S., accounting for 43% of the mix... California and Nevada both surpassed 30% annual share of solar in their electricity mix for the first time last year (32% and 30%, respectively). California's battery growth was key to its solar success. It installed 20% more battery capacity than it did solar capacity, which helped it transfer a significant share of its daytime solar to the evening. Texas installed more solar and battery capacity than even California. Yet the growth of solar was uneven — 28 states generated less than 5% of their electricity from solar in 2024, highlighting significant untapped potential — even before adding battery storage. The article includes this observation from Dave Jones, chief analyst at Ember. "The fall in battery costs is a gamechanger for how much solar the U.S. electricity grid could integrate in the near future." Electrek notes that "After being stagnant for 14 years, electricity demand started rising in recent years and saw a 3% increase in 2024, marking the fifth-highest level of rise this century..." Natural gas grew three times more than the decline in coal, increasing power sector CO2 emissions slightly (0.7%). Coal fell by the second smallest amount since 2014, as gas and clean energy growth met rising electricity demand, whereas historically, they have replaced coal. Despite growing emissions, the carbon intensity of electricity continued to decline. The rise in power demand was much faster than the rise in power sector CO2 emissions, making each unit of electricity likely the cleanest it has ever been.

    10 Million Cubans Suffer Nationwide Power Outage
    "Cuba's power grid collapsed Friday night," reports CNN, "triggering a nationwide power outage and plunging its more than 10 million people into darkness." Video filmed by CNN in the capital Havana showed streets and buildings shrouded in total darkness, as people used electric torches to navigate the streets. By Saturday morning, the Cuban government officials said that "microsystems" — pockets of electricity — had been restored in some cities. However, it remains unclear when the island's power system would be fully online again and most people remained in the dark... It marks the latest in a series of failures on the Caribbean island struggling with creaking infrastructure, natural disasters and economic turmoil... For nearly a week in October, most of Cuba suffered near-total blackouts, the worst energy outages in decades. While Cubans are used to frequent power outages, to have another nationwide backcourt — the fourth in six months — was unsettling for many people who need electricity to cook and refrigerate food that otherwise spoils quickly in the tropical heat. "Many residents posted on online sites looking for propane, charcoal, and fuel for generators..."
