Millions of Fruit Flies Will Be Dropped On Los Angeles

"Earlier this month, the California Department of Food and Agriculture quarantined 69 square miles of metro L.A. after invasive and destructive Mediterranean fruit flies were found at a home in the Leimert Park neighborhood," notes The Hill. Officials are now planning to use small planes to drop millions of fruit flies over Los Angeles in an effort to eradicate an invasive and destructive species of the insects. From the report: Jay Van Rein, a spokesperson for the CDFA, told SFGATE that officials plan to drop approximately 250,000 sterile male fruit flies per square mile in the quarantine area every week for six months, or perhaps longer. The sterile males mate with the females, which fail to produce offspring, reducing the population over time. Van Rein says the Preventative Release Program (PRP), as it's called, has been used effectively to manage invasive species since 1996. The quarantine radius includes parts of downtown and South L.A., Hyde Park, Baldwin Hills, Culver City, Inglewood, Pico-Robertson and Mid-Wilshire. Those who live within the zone are urged not to transport any fruits or vegetables from their property and to double-bag them in plastic before tossing them in the trash. The Mediterranean fruit fly is very tiny -- only about 1/4 inch in length -- but they can potentially cause hundreds of millions of dollars in damage to crops if left unchecked, officials said. When a female lays eggs in a fruit or vegetable, they hatch into maggots that tunnel through it and cause rot.

Asahi Linux Goes From Apple Silicon Port Project To macOS Bug Hunters

Richard Speed reports via The Register: Asahi Linux, a project to port Linux to Apple Silicon Macs, has reported a combination of bugs in Apple's macOS that could leave users with hardware in a difficult-to-recover state. The issues revolve around how recent versions of macOS handle refresh rates, and MacBook Pro models with ProMotion displays (the 14 and 16-inch versions) are affected. According to the Asahi team, the bugs lurk in the upgrade and boot process and, when combined, can create a condition where a machine always boots to a black screen, and a Device Firmware Update (DFU) recovery is needed. Asahi Linux's techies have looked into the issue, having first suspected it had something to do with either having an Asahi Linux installation on a Mac and then upgrading to macOS Sonoma or installing Asahi Linux after a Sonoma upgrade. However, the issue appears to be unconnected to the project. The team said: "As far as we can tell, ALL users who upgraded to Sonoma the normal way have an out-of-date or even broken System RecoveryOS, and in particular MacBook Pro 14" and 16" owners are vulnerable to ending up with a completely unbootable system." While this might sound alarming, the team was at pains to assure users that data was not at risk and only certain versions of macOS were affected -- Sonoma 14.0+ and Ventura 13.6+. The first bug is related to macOS Sonoma using the previously installed version as System Recovery, which can cause problems when an older RecoveryOS runs into newer firmware. The second occurs if a display is configured to a refresh rate other than ProMotion. According to the Asahi Linux team, the system will no longer be able to boot into old macOS installs or Asahi Linux. "This includes recovery mode when those systems are set as the default boot OS, and also System Recovery at least until the next subsequent OS upgrade." The team noted: "Even users with just 13.6 installed single-boot are affected by this issue (no Asahi Linux needed). "We do not understand how Apple managed to release an OS update that, when upgraded to normally, leaves machines unbootable if their display refresh rate is not the default. This seems to have been a major QA oversight by Apple."
