Toyota’s Prototype ‘Cartridge’ Is a Way To Make Hydrogen Portable

Toyota and its subsidiary Woven Planet have unveiled a new portable cartridge prototype for hydrogen. “The idea is that they can be filled up at a dedicated facility, transported where needed, then returned when you receive your next shipment,” reports Engadget. From the report: The cartridges would be relatively small at 16 inches long, 7 inches in diameter and about 11 pounds in weight. Toyota calls them “portable, affordable, and convenient energy that makes it possible to bring hydrogen to where people live, work, and play without the use of pipes.. [and] swappable for easy replacement and quick charging.”

They could be useful for “mobility [i.e. hydrogen cars], household applications, and many future possibilities we have yet to imagine,” Toyota said. It didn’t mention any specific uses, but it said that “one hydrogen cartridge is assumed to generate enough electricity to operate a typical household microwave for approximately 3-4 hours.”

In its press release, Toyota acknowledges that most hydrogen is made from fossil fuels and so not exactly green. But it thinks that it’ll be generated with low carbon emissions in the future, and that the cartridges could help with some of the infrastructure issues. Toyota plans to test that theory by conducting proof of concept trials in various places, including its “human-centered smart city of the future,” Woven City in Susono City, Zhizuoka Prefecture in Japan. The company is also “working to build a comprehensive hydrogen-based supply chain aimed at expediting and simplifying production, transport, and daily usage,” it said.

Older iPads May Soon Be Able To Run Linux

Older iPads with the Apple A7- and A8-based chips may soon be able to run Linux. “Developer Konrad Dybcio and a Linux enthusiast going by “quaack723″ have collaborated to get Linux kernel version 5.18 booting on an old iPad Air 2, a major feat for a device that was designed to never run any operating system other than Apple’s,” reports Ars Technica. From the report: The project appears to use an Alpine Linux-based distribution called “postmarketOS,” a relatively small but actively developed distribution made primarily for Android devices. Dybcio used a “checkm8” hashtag in his initial tweet about the project, strongly implying that they used the “Checkm8” bootrom exploit published back in 2019 to access the hardware. For now, the developers only have Linux running on some older iPad hardware using A7 and A8-based chips — this includes the iPad Air, iPad Air 2, and a few generations of iPad mini. But subsequent tweets imply that it will be possible to get Linux up and running on any device with an A7 or A8 in it, including the iPhone 5S and the original HomePod.

Development work on this latest Linux-on-iDevices effort is still in its early days. The photos that the developers shared both show a basic boot process that fails because it can’t mount a filesystem, and Dybcio notes that basic things like USB and Bluetooth support aren’t working. Getting networking, audio, and graphics acceleration all working properly will also be a tall order. But being able to boot Linux at all could draw the attention of other developers who want to help the project.

Compared to modern hardware with an Apple M1 chip, A7 and A8-powered devices wouldn’t be great as general-purpose Linux machines. While impressive at the time, their CPUs and GPUs are considerably slower than modern Apple devices, and they all shipped with either 1GB or 2GB of RAM. But their performance still stacks up well next to the slow processors in devices like the Raspberry Pi 4, and most (though not all) A7 and A8 hardware has stopped getting new iOS and iPadOS updates from Apple at this point; Linux support could give some of these devices a second life as retro game consoles, simple home servers, or other things that low-power Arm hardware is good for.

Dogs Can Detect COVID-19 With Great Accuracy

According to a new study, dogs were able to better detect COVID-19 than PCR antigenic tests in both symptomatic and asymptomatic people. Slashdot Falconhell shares the report via The Guardian: In the study, trained dogs were able to detect Covid in 97% of symptomatic cases and nearly 100% of asymptomatic cases. The study featured 335 participants from Covid screening centers in Paris. Of the participants, 109 were positive with Covid, including 31 who were asymptomatic. The detection dogs, provided by French fire stations and the United Arab Emirates, received three to six weeks of training, depending on if a dog was previously trained for odor detection. The dogs sniffed samples of human sweat placed in an olfaction cone. If a dog detected Covid, it sat down in front of the cone.

Ultimately, the trained dogs were more sensitive to positive cases. Nasal PCR tests were better able to better detect negative cases. In two false positive cases, dogs falsely identified other coronavirus respiratory illness strains that were not Covid. While there have been previous studies on the capability of dogs to detect Covid, this is believed to be the first to compare the accuracy of dogs to antigenic tests. The study has been published in the journal Plos One.

Consumers Embrace Milk Carton QR Codes, May Cut Food Waste

The “use-by” and “best-by” dates printed on milk cartons and gallon jugs may soon become a thing of the past, giving way to more accurate and informative QR codes. Phys.Org reports: A new Cornell University study finds that consumers will use the QR codes to better depict how long the milk is drinkable and create substantially less agricultural and food waste. In the U.S., dairy products are among the top three food groups with the largest share of wasted food, said Samantha Lau, a doctoral student in food science who works in the lab of Martin Wiedmann, the professor of food safety in the College of Agriculture and Life Sciences.

In the early spring semester, Lau, also working with Cornell’s Milk Quality Improvement Program, connected with the Cornell Dairy Bar, which sells fluid milk in addition to ice cream on campus. She wanted to assess consumer acceptance for QR code technology that may one day replace the static best-by or sell-by dates commonly found on food products. Customers had a choice: purchasing milk with printed best-by dates, or buying containers with QR codes, which when scanned by a smart phone, would display the best-by date.

In the same Cornell Dairy Bar study, Lau placed a dynamic pricing element where consumers were encouraged to purchase milk with a shorter remaining shelf life — by offering a price discount as the best-by date approached. “During two-month study, over 60% of customers purchased the milk with the QR code, showing a considerable interest in using this new technology,” Lau said. “This revealed that the use of QR codes on food products can be an innovative way to address the larger issue of food waste.” Wiedmann says the technology also exists where smart milk cartons could communicate with smart refrigerators to inform a household of the need for fresh milk.

The study has been published in the Journal of Dairy Science.

Banking Giant Capital One Enters B2B Software Industry With Launch of New Business

Capital One, a major player in America’s banking industry with $434 billion in assets and more than 100 million customers, is launching Capitol One Software, “a business that develops and sells software products to companies scaling up their use of data and cloud computing,” reports Forbes. From the report: The new venture, which has been created by Capital One’s CEO and founder, Rich Fairbank, is based at the company’s headquarters in McLean, Virginia, and has its own dedicated personnel as well as access to software developers in Capital One’s 12,000-strong technology team. Its first product, Capital One Slingshot, helps companies speed up their adoption of Snowflake, a popular cloud data platform, and manage costs associated with it. […] Ravi Raghu, the head of Capital One Software, says executives at Capital One see its creation as a natural evolution of the overall company’s digital journey. “We’ve been talking of Capital One as a technology company for a while now. The best proof of that is [to become] a technology company that’s actually selling software. That innovation just runs in our DNA.”

Still, making Capital One Software a success will be no slam dunk. The markets the new business is targeting are big but they are also full of formidable competitors whose sole focus is on software and there are significant costs associated with things such as building teams that consult with customers to help them get the most out of the products they buy. Capital One may also need to reassure investors, who have seen its share price fall by almost 12% this year to $127.86 at close of trading on May 31, that its move into the software business will not distract executives from its core finance ones, especially as the economy shows signs it may be tilting towards recession.

India Withdraws Warning on Biometric ID Sharing Following Online Uproar

Silicon Valley Investors Give Startups Survival Advice for Downturn

After years of funneling cash into startups’ grand ambitions, Silicon Valley’s investors are engaging in the grim ritual of delivering survival advice to their portfolio companies. From a report: In recent online slide presentations, blog posts and social-media threads, venture-capital doyens including Lightspeed Venture Partners, Craft Ventures, Sequoia Capital and Y Combinator are telling the founders that they need to take emergency action for what could be the sharpest turn in more than a decade. Their advice includes cutting costs, preserving cash and jettisoning hopes that hedge funds or other investors will swoop in with big checks.

“The boom times of the last decade are unambiguously over,” Lightspeed, which has backed companies including social network Snap and crypto exchange FTX, wrote in a dispatch for startup executives that was posted on Medium, a publishing platform, this month. The investors’ admonitions are a departure from the growth-above-all mantra for startups in recent years, and come as the venture market is showing signs of sputtering. Funding for global startups — at around $58 billion in commitments midway through the second quarter — is on pace to drop by about one-fifth in the period compared with the previous quarter, according to analytics firm CB Insights. The tech-heavy Nasdaq Composite Index is down about 25% from its all-time high in November, and SoftBank Group, which has poured more than $100 billion into investments, this month reported a $26.2 billion loss in the first quarter as valuations plummeted in its portfolio of tech companies.

Google Quietly Bans Deepfake Training Projects on Colab

Google has quietly banned deepfake projects on its Colaboratory (Colab) service, putting an end to the large-scale utilization of the platform’s resources for this purpose. From a report: Colab is an online computing resource that allows researchers to run Python code directly through the browser while using free computing resources, including GPUs, to power their projects. Due to the multi-core nature of GPUs, Colab is ideal for training machine learning projects like deepfake models or for performing data analysis. Deepfakes can be trained to swap faces on video clips, adding realistic facial expressions to make the result appear genuine, although it’s fake. They have been used for spreading fake news, creating revenge porn, or for fun. However, the lack of ethical limitations in their use has been the source of controversy and concern.

‘Turn an Old PC Into a High-End Amiga with AmiKit’

Mike Bouma (Slashdot reader #85,252) writes:
AmiKit is a compilation of pre-installed and pre-configured Amiga programs running emulated on Windows, macOS, and Linux (as well as running on classic 68K Amigas expanded with a Vampire upgrade card).

Besides original Workbench (Commodore’s desktop environment/graphical filemanager), AmiKit provides Directory Opus Magellan and Scalos as desktop replacements and its “Rabbit Hole” feature allows you to launch Windows, Mac or Linux applications directly from your Amiga desktop! Anti-aliased fonts, Full HD 32-bit screen modes and DualPNG Icons support is included and this package comes with exclusive versions of the Master Control Program (MCP) and MUI 5 (Magic User Interface).

The original AmigaOS (version 3.x) and Kickstart ROM (version 3.1) are required, also the recently released AmigaOS 3.2 is supported. You can also get the needed files from the Amiga Forever package(s). It even supports emulating AmigaOS 4.x (for PowerPC) easily through Flower Pot.

Here’s an extensive overview video by Dan Wood. An Amiga Future review of an earlier 2017 version can be read here.

“Everything began in 1994 when my parents bought an Amiga 500 for me and my brother,” explains AmiKit’s developer.

“I was 14 years old…”

Fast forward to 2005, the AmiKit was born — an emulated environment including more than 350 programs. It fully replaced my old Amiga and it became a legend in the community over the years.

Fast forward to 2017, a brand new AmiKit X is released, originally developed for A.L.I.C.E., followed by the XE version released in 2019, Vampire edition in 2020 and Raspberry Pi in 2021. The latest & greatest version was released in 2020.

When someone, who has never heard about Amiga before, asks me why I would want to turn current modern computer into something retro and old fashioned, my short answer is: “Simply because I love Amiga!”
