The Namibian fairy circle debate rages on: Could it be sand termites after all?

Himba bushmen in the Namibian grasslands have long passed down legends about the region’s mysterious fairy circles: bare, reddish-hued circular patches that are also found in northwestern Australia. In the last 10 years, scientists have heatedly debated whether these unusual patterns are due to sand termites or to an ecological version of a self-organizing Turing mechanism. Last year, a team of scientists reported what they deemed definitive evidence of the latter, thus ruling out sand termites, but their declaration of victory may have been premature. A recent paper published in the journal Perspectives in Plant Ecology, Evolution, and Systematics offers a careful rebuttal of those 2022 findings, concluding that sand termites may be to blame after all.

As we’ve reported previously, the fairy circles can be as large as several feet in diameter. Dubbed “footprints of the gods,” it’s often said they are the work of the Himba deity Mukuru, or an underground dragon whose poisonous breath kills anything growing inside those circles. Scientists have their own ideas.

One theory—espoused by study co-author Norbert Jürgens, a biologist at the University of Hamburg in Germany—attributed the phenomenon to a particular species of termite (Psammmotermes allocerus), whose burrowing damages plant roots, resulting in extra rainwater seeping into the sandy soil before the plants can suck it up—giving the termites a handy water trap as a resource. As a result, the plants die back in a circle from the site of an insect nest. The circles expand in diameter during droughts because the termites must venture farther out for food.

Waymo pushes back its self-driving truck efforts to focus on ride hailing

Don’t expect to see many Waymo-powered autonomous big rigs in the near future. Waymo now plans to “push back” its driverless trucking efforts and shift its attention toward its One ride-hailing service. The move will help the company concentrate on making these self-driving taxis a “commercial success,” according to co-CEOs Dmitri Dolgov and Tekedra Mawakana.

Waymo justified the decision by pointing to “significant” growth in demand for its robotaxis in Los Angeles, Phoenix and San Francisco. It also noted rapid upgrades to Driver, the AI system that handles its autonomous cars. There’s “tremendous momentum” in One, the co-chiefs say, and the new strategy will help make the most of this trend.

The Alphabet-owned brand still intends to work with Daimler on self-driving semi trucks. It’s shifting most of its technical development toward Waymo One, but believes work on Driver (particularly for highway driving) will indirectly benefit trucking. There’s no updated timeline for when trucks may reach the roads, but TechCrunchunderstands only a handful of workers will lose jobs as a result of the transition. Most have taken other positions at Waymo.

Waymo started testing autonomous big rig trucks in 2017, with rapid expansions in 2019 and 2020 that included the launch of its Via cargo transportation division. The firm won the attention of major partners, including UPS and former rival Uber Freight. However, there’s no doubt that Waymo One was the star and won the most interest. Uber even expects to offer Waymo rides and deliveries in Phoenix later this year.

The change isn’t guaranteed to pan out. While Waymo is closer to offering paid rides in multiple markets, it’s still facing opposition from officials who are concerned about safety issues. Driverless cars have blocked traffic, interfered with first responder vehicles and otherwise caused problems, and there’s a call for regulators to limit just where and when robotaxis can operate.

[$] A status update for U-Boot

The U-Boot
“universal boot loader” is used extensively in the embedded-Linux world.
At the 2023 Embedded
Open Source Summit
(EOSS), Simon Glass gave a presentation (slides,
YouTube video) on
the status of the project, with a focus on new features added over the last
several years. He also wanted to talk about complexity in the firmware
world, which he believes is increasing, and how U-Boot can help manage that
complexity. The talk was something of a grab bag of ideas and changes
throughout the increasingly large footprint of the project.

Arrival of eSIM is Altering How Consumers Interact With Operators

OpenSignal blog: While eSIM adoption in the mobile market has been arriving for some time, Apple’s move to make eSIM the only option for iPhone 14 range in the U.S. is propelling the worldwide shift towards eSIM technology. Opensignal’s latest analysis reveals a significant surge in the proportion of users switching their operator among those who use an eSIM across seven examined markets — Brazil, Indonesia, Singapore, South Korea, Taiwan, the U.K. and the U.S.

The switch from physical to embedded SIM cards threatens to alter how consumers switch operators and encourages operators to adopt new tactics to retain and acquire users, for example operators can offer network trials from within an app that provisions an eSIM immediately. eSIM also means the risks to operators of dual SIM devices that have long been common in many international markets are arriving in operator-controlled markets too, such as the U.S. and South Korea. Even on smartphones sold by operators, eSIM support is usually present in addition to a physical SIM, making them dual-SIM devices.

Google added eSIM-support to the Pixel range in 2017, Samsung added eSIM support to 2019’s Galaxy S20 flagship. While Apple first added eSIM to their phones in 2018 with the iPhone Xs, it switched to selling exclusively eSIM models in the U.S. with the iPhone 14 range in late 2022. South Korea is also a special case — eSIM support for domestic customers only began in mid-2022, before this point it was only available to international travelers. Notably, Samsung responded by introducing eSIM to a selection of its flagship devices in the home market, which had not been previously available there.

Google says it will start downranking non-tablet apps in the Play Store

Following the release of the Pixel Tablet and Pixel Fold, Google wants developers to take big-screen apps more seriously. Asking nicely rarely works, so Google is changing the Play Store ranking algorithms to increase the visibility of apps that better support large screens.

Google’s blog post says:

Apps and games that adhere to our large screen app quality guidelines will now be ranked higher in search and Apps and Games Home. This helps users find apps that resize well, aren’t letterboxed, and support both portrait and landscape orientations. Editors’ Choice and other curated collections and articles will also consider these criteria going forward, creating new featuring opportunities for optimized apps.

The large screen app guidelines have various tiers, but they recommend keyboard, mouse, and stylus support, a two-pane tablet layout, drag-and-drop support, and foldable display awareness. The post also reiterates some improvements that Google has already rolled out, like showing tablet screenshots to tablet users and downranking apps that crash a lot.

X tells advertisers to spend $1,000 per month or risk losing verification status

Amid its rebranding to X, Twitter is reportedly hardballing advertisers in an effort to increase its bottom line. Reports earlier this month suggested that Twitter’s revenue had dropped by a staggering 50 percent. The company’s latest strategy to increase revenue, according to The Wall Street Journal, is asking brands to spend at least $1,000 per month on ads in order to maintain their verified status on the platform.

Responding to a tweet about The Wall Street Journal’s report, Musk says that the “moderately high” cost is a preventative measure to help reduce the number of scammers creating “millions of accounts” on the platform. Musk added that brands could instead choose to pay $1,000 per month for the company’s verified organization badge.

It’s clear that Twitter is looking for ways to reduce its losses, and the company’s main source of revenue is advertising. The Wall Street Journal also reports that Twitter is slashing prices on some of its advertising slots. For example, Twitter is giving all new bookings a 50 percent discount through July 31st. The company claims that the point of these discounts is to allow advertisers to “gain reach during crucial moments” such as sporting events.

While the $1,000 monthly rate is unlikely to be an issue for larger brands, the new change could hurt smaller businesses that don’t want to or don’t have the extra budget to commit.
