RISC-V Guns for Raspberry Pi, Legacy Chips

Two hardware makers are planning to offer chips later this year featuring the RISC-V free and open architecture standard, joining the $180 Linux-capable StarFive VisionFive RISC-V board that went on sale in January. In late June, Pine64 said it was designing a single-board computer for the market now dominated by Raspberry Pi, and Xcalibyte and DeepComputing said they would begin shipping RISC-V-based laptops at the end of the summer.

The twelve-year-old RISC-V computer instruction set architecture standard belongs to no one and everyone, giving it unique appeal compared to Intel and ARM chips, which require licensing fees. At the same time, RISC-V’s relative novelty and reduced feature set and support are barriers to more widespread adoption. An open source development effort last year to produce a Linux-capable mini-PC with RISC-V ended in failure. VisionFive was involved in that project, too. Like any new tech ecosystem, software support for RISC-V is more limited than in Raspberry Pi’s robust development community, says independent software engineer Leon Anavi in a review of the VisionFive. That said, he encouraged viewers to join in and contribute to the growing RISC-V community.

Europe Expands Virtual Borders To Thwart Migrants

IT WAS AFTER MIDNIGHT in the Maltese search-and-rescue zone of the Mediterranean when a rubber boat originating from Libya carrying dozens of migrants encountered a hulking cargo ship from Madeira and a European military aircraft. The ship’s captain stopped the engines, and the aircraft flashed its lights at the rubber boat. But neither the ship nor the aircraft came to the rescue. Instead, Maltese authorities told the ship’s captain to wait for vessels from Malta to pick up the migrants. By the time those boats arrived, three migrants had drowned trying to swim to the idle ship.

Countries Debate Openness of Future National IDs

Kenya’s High Court ruled Thursday that a recent amendment requiring citizens to register for a national biometric digital identification system overreached on some counts, such as allowing for links to DNA or GPS records, and failed to guarantee sufficient inclusion of Kenyan residents. 

The ID system, called the National Integrated Identity Management System (NIIMS), was a homegrown answer to India’s pioneering Aadhaar system, which two years ago faced its own Indian Supreme Court ruling that upheld some components while modifying others. 

More than half of African countries are developing some form of biometric or digital national ID in response to major international calls to establish legal identification for the almost 1 billion people who now lack it. But this ID boom, also taking place outside Africa, often gets ahead of data protection laws, as occurred in Kenya.

Automated Eyes Watch Plants Grow

A decade ago, a group of crop scientists set out to grow the same plants in the same way. They started with the same breeds and adhered to strict growing protocols, but nonetheless harvested a motley crop of plants that varied in leaf size, skin-cell density, and metabolic ability. Small differences in light levels and plant handling had produced outsize changes to the plants’ physical traits, or phenome.

The plunging price of genomic sequencing has made it easier to examine a plant’s biological instructions, but researchers’ understanding of how a plant follows those instructions in a given environment lags. “There is a major bottleneck for a lot of breeders to be able to get their phenotypic evaluation in line with their genetic capabilities,” says Bas van Eerdt, business development director at PhenoKey, in ’s-Gravenzande, Netherlands.
