New research suggests volcanic eruptions can trigger periods of rapid ice sheet melting… “Over a time span of 1,000 years, we found that volcanic eruptions generally correspond with enhanced ice sheet melting within a year or so,” Francesco Muschitiello, a postdoctoral researcher at Columbia University’s Lamont-Doherty Earth Observatory, said in a news release. The volcanoes of note weren’t situated next-door, but thousands of miles from the ice sheet, a reminder of the unexpected global impacts of volcanic activity.

The new research — detailed this week in the journal Nature Communications — suggests ash ejected into the atmosphere by erupting volcanoes can be deposited thousands of miles away. When it’s deposited on ice sheets, the dark particles cause the ice to absorb more thermal energy and accelerate melting… Some scientists have even suggested melting encouraged by volcanic eruptions could trigger even more eruptions, a positive feedback loop. As glaciers and ice sheets melt, pressure is relieved from the planet’s crust, allowing magma to rise to the surface.

“San Francisco company Purism announced that they are now offering their Librem laptops with the Intel Management Engine disabled,” writes Slashdot reader boudie2. Purism describes Management Engine as “a separate CPU that can run and control a computer even when powered off.”

HardOCP reports that Management Engine “is widely despised by security professionals and privacy advocates because it relies on signed and secret Intel code, isn’t easily alterable, isn’t fully documented, and has been found to be vulnerable to exploitation… In short, it’s a tiny potentially hackable computer in your computer that you cannot totally control, nor opt-out of, but it can totally control your system.”

Purism writes:
Disabling the Management Engine is no easy task, and it has taken security researchers years to find a way to properly and verifiably disable it. Purism, because it runs coreboot and maintains its own BIOS firmware update process, has been able to release and ship coreboot that disables the Management Engine from running, directly halting the ME CPU without the ability of recovery… “Disabling the Management Engine, long believed to be impossible, is now possible and available in all current Librem laptops. It is also available as a software update for previously shipped recent Librem laptops,” says Todd Weaver, Founder & CEO of Purism.

“[N]early 200 F-35s might permanently remain unready for combat because the Pentagon would rather buy new aircraft than upgrade the ones the American people have already paid for,” according to one defense news site. And now Bloomberg reports:
The Pentagon is accelerating production of Lockheed Martin Corp.’s F-35 jet even though the planes already delivered are facing “significantly longer repair times” than planned because maintenance facilities are six years behind schedule, according to a draft audit. The time to repair a part has averaged 172 days — “twice the program’s objective” — the Government Accountability Office, Congress’s watchdog agency, found. The shortages are “degrading readiness” because the fighter jets “were unable to fly about 22 percent of the time” from January through August for lack of needed parts.
The Pentagon has said soaring costs to develop and produce the F-35, the costliest U.S. weapons system, have been brought under control, with the price tag now projected at $406.5 billion. But the GAO report raises new doubts about the official estimate that maintaining and operating them will cost an additional $1.12 trillion over their 60-year lifetime.
Slashdot reader schwit1 writes, “This is akin to buying an exotic car you can barely afford, without also budgeting for insurance, repairs, and tuneups.”
