Extreme California Heat Knocks Key Twitter Data Center Offline (cnn.com) 62

Extreme heat in California has left Twitter without one of its key data centers, and a company executive warned in an internal memo obtained by CNN that another outage elsewhere could result in the service going dark for some of its users. CNN reports: "On September 5th, Twitter experienced the loss of its Sacramento (SMF) datacenter region due to extreme weather. The unprecedented event resulted in the total shutdown of physical equipment in SMF," Carrie Fernandez, the company's vice president of engineering, said in an internal message to Twitter engineers on Friday. Major tech companies usually have multiple data centers, in part to ensure their service can stay online if one center fails; this is known as redundancy.

As a result of the outage in Sacramento, Twitter is in a "non-redundant state," according to Fernandez's Friday memo. She explained that Twitter's data centers in Atlanta and Portland are still operational but warned, "If we lose one of those remaining datacenters, we may not be able to serve traffic to all Twitter's users." The memo goes on to prohibit non-critical updates to Twitter's product until the company can fully restore its Sacramento data center services. "All production changes, including deployments and releases to mobile platforms, are blocked with the exception of those changes required to address service continuity or other urgent operational needs," Fernandez wrote.
In a statement about the Sacramento outage, a Twitter spokesperson told CNN, "There have been no disruptions impacting the ability for people to access and use Twitter at this time. Our teams remain equipped with the tools and resources they need to ship updates and will continue working to provide a seamless Twitter experience."

Retbleed Fix Slugs Linux VM Performance By Up To 70 Percent (theregister.com) 33

VMware engineers have tested the Linux kernel's fix for the Retbleed speculative execution bug, and report it can impact compute performance by a whopping 70 percent. The Register reports: In a post to the Linux Kernel Mailing List titled "Performance Regression in Linux Kernel 5.19", VMware performance engineering staffer Manikandan Jagatheesan reports the virtualization giant's internal testing found that running Linux VMs on the ESXi hypervisor using version 5.19 of the Linux kernel saw compute performance dip by up to 70 percent when using single vCPU, networking fall by 30 percent and storage performance dip by up to 13 percent. Jagatheesan said VMware's testers turned off the Retbleed remediation in version 5.19 of the kernel and ESXi performance returned to levels experienced under version 5.18.

Because speculative execution exists to speed processing, it is no surprise that disabling it impacts performance. A 70 percent decrease in computing performance will, however, have a major impact on application performance that could lead to unacceptable delays for some business processes. VMware's tests were run on Intel Skylake CPUs -- silicon released between 2015 and 2017 that will still be present in many server fleets. Subsequent CPUs addressed the underlying issues that allowed Retbleed and other Spectre-like attacks.

Runway Teases AI-Powered Text-To-Video Editing Using Written Prompts (arstechnica.com) 10

An anonymous reader quotes a report from Ars Technica: In a tweet posted this morning, artificial intelligence company Runway teased a new feature of its AI-powered web-based video editor that can edit video from written descriptions, often called "prompts." Runway's "Text to Video" demonstration reel shows a text input box that allows editing commands such as "import city street" (suggesting the video clip already existed) or "make it look more cinematic" (applying an effect). It depicts someone typing "remove object" and selecting a streetlight with a drawing tool that then disappears (from our testing, Runway can already perform a similar effect using its "inpainting" tool, with mixed results). The promotional video also showcases what looks like still-image text-to-image generation similar to Stable Diffusion (note that the video does not depict any of these generated scenes in motion) and demonstrates text overlay, character masking (using its "Green Screen" feature, also already present in Runway), and more.

Video generation promises aside, what seems most novel about Runway's Text to Video announcement is the text-based command interface. Whether video editors will want to work with natural language prompts in the future remains to be seen, but the demonstration shows that people in the video production industry are actively working toward a future in which synthesizing or editing video is as easy as writing a command. [...] Runway is available as a web-based commercial product that runs in the Google Chrome browser for a monthly fee, which includes cloud storage for about $35 per year. But the Text to Video feature is in closed "Early Access" testing, and you can sign up for the waitlist on Runway's website.

Android 13 Raises Minimum System Requirement To 2GB of RAM, 16GB of storage 50

Android 13 has recently hit the streets, and with it, Google is raising the minimum requirements for Android phones. From a report: Google's latest blog post announced that the minimum amount of RAM for Android Go, the low-end version of Android, is now 2GB for Android 13, whereas previously, it was 1GB. Esper's Mishaal Rahman and Google Product Expert Jason Bayton also claim the minimum storage requirements have been bumped up to 16GB, though Google doesn't seem to have publicly documented this anywhere. The increase in system requirements means any phone that doesn't meet the minimum specs won't be able to update to Android 13. New phones launching with Android 13 will need to meet the minimum requirements to be eligible for Play Store licensing, though launching with an older version of Android (with lower requirements) will still be an option for a while. Technically, anyone can grab the Android source code and build anything with it, but if you want to license the Google apps and have access to the Google-trademarked brand "Android," you'll need to comply with Google's rules.

Asus Packs 12-Core Intel i7 Into a Raspberry Pi-Sized Board (theregister.com) 30

An anonymous reader quotes a report from The Register: The biz's GENE-ADP6, announced this week, can pack as much as a 12-core/16-thread Intel processor with Iris Xe graphics into a 3.5-inch form factor. The diminutive system is aimed at machine-vision applications and can be configured with your choice of Intel silicon including Celeron, or Core i3, i5, or a choice of 10 or 12-core i7 processors. As with other SBCs we've seen from Aaeon and others, the processors aren't socketed so you won't be upgrading later. This device is pretty much aimed at embedded and industrial use, mind. All five SKUs are powered by Intel's current-gen Alder Lake mobile processor family, including a somewhat unusual 5-core Celeron processor that pairs a single performance core with four efficiency cores. However, only the i5 and i7 SKUs come equipped with Intel's Iris Xe integrated graphics. The i3 and Celeron are stuck on UHD graphics. The board can be equipped with up to 64GB of DDR5 memory operating at up to 4800 megatransfers/sec by way of a pair of SODIMM modules.

For I/O the board features a nice set of connectivity including a pair of NICs operating at 2.5 Gbit/sec and 1 Gbit/sec, HDMI 2.1 and Display Port 1.4, three 10Gbit/sec-capable USB 3.2 Gen 2 ports, and a single USB-C port that supports up to 15W of power delivery and display out. For those looking for additional connectivity for their embedded applications, the system also features a plethora of pin headers for USB 2.0, display out, serial interfaces, and 8-bit GPIO. Storage is provided by your choice of a SATA 3.0 interface or a m.2 mSATA/NVMe SSD. Unlike Aaeon's Epic-TGH7 announced last month, the GENE-ADP6 is too small to accommodate a standard PCIe slot, but does feature a FPC connector, which the company says supports additional NVMe storage or external graphics by way of a 4x PCIe 4.0 interface.

US State of Virginia Has More Datacenter Capacity Than Europe or China (theregister.com) 42

The state of Virginia has over a third of America's hyperscale datacenter capacity, and this amounts to more than the entire capacity of China or the whole of Europe, highlighting just how much infrastructure is concentrated along the so-called Datacenter Alley. The Register reports: These figures come from Synergy Research Group, which said that the US accounts for 53 percent of global hyperscale datacenter capacity, as measured by critical IT load, at the end of the second quarter of 2022. The remainder is relatively evenly split between China, Europe, and the rest of the world. While few would be surprised at the US accounting for the lion's share of datacenter capacity, the fact that so much is concentrated in one state could raise a few eyebrows, especially when it is centered on a small number of counties in Northern Virginia -- typically Loudoun, Prince William, and Fairfax -- which make up Datacenter Alley.

"Hyperscale operators take a lot of factors into account when deciding where to locate their datacenter infrastructure," said Synergy chief analyst John Dinsdale. "This includes availability of suitable real estate, cost and availability of power supply options, proximity to customers, the risk of natural disasters, local incentives and approvals processes, the ease of doing business and internal business dynamics, and this has inevitably led to some hyperscale hot spots." Amazon in particular locates a large amount of its datacenter infrastructure in Northern Virginia, with Microsoft, Facebook, Google, ByteDance, and others also having a major presence, according to Synergy. The big three cloud providers -- Amazon, Microsoft and Google -- have the broadest hyperscale bit barn footprint, with each of these having over 130 datacenters of the 800 or so around the globe. When measured in datacenter capacity, the leading companies are Amazon, Google, Microsoft, Facebook, Alibaba and Tencent, according to Synergy.

Facebook Engineers: We Have No Idea Where We Keep All Your Personal Data (theintercept.com) 69

An anonymous reader quotes a report from The Intercept: In March, two veteran Facebook engineers found themselves grilled about the company's sprawling data collection operations in a hearing for the ongoing lawsuit over the mishandling of private user information stemming from the Cambridge Analytica scandal. The hearing, a transcript of which was recently unsealed (PDF), was aimed at resolving one crucial issue: What information, precisely, does Facebook store about us, and where is it? The engineers' response will come as little relief to those concerned with the company's stewardship of billions of digitized lives: They don't know.

The admissions occurred during a hearing with special master Daniel Garrie, a court-appointed subject-matter expert tasked with resolving a disclosure impasse. Garrie was attempting to get the company to provide an exhaustive, definitive accounting of where personal data might be stored in some 55 Facebook subsystems. Both veteran Facebook engineers, with according to LinkedIn two decades of experience between them, struggled to even venture what may be stored in Facebook's subsystems. "I'm just trying to understand at the most basic level from this list what we're looking at," Garrie asked. "I don't believe there's a single person that exists who could answer that question," replied Eugene Zarashaw, a Facebook engineering director. "It would take a significant team effort to even be able to answer that question." When asked about how Facebook might track down every bit of data associated with a given user account, Zarashaw was stumped again: "It would take multiple teams on the ad side to track down exactly the -- where the data flows. I would be surprised if there's even a single person that can answer that narrow question conclusively." [...]

Facebook's stonewalling has been revealing on its own, providing variations on the same theme: It has amassed so much data on so many billions of people and organized it so confusingly that full transparency is impossible on a technical level. In the March 2022 hearing, Zarashaw and Steven Elia, a software engineering manager, described Facebook as a data-processing apparatus so complex that it defies understanding from within. The hearing amounted to two high-ranking engineers at one of the most powerful and resource-flush engineering outfits in history describing their product as an unknowable machine. The special master at times seemed in disbelief, as when he questioned the engineers over whether any documentation existed for a particular Facebook subsystem. "Someone must have a diagram that says this is where this data is stored," he said, according to the transcript. Zarashaw responded: "We have a somewhat strange engineering culture compared to most where we don't generate a lot of artifacts during the engineering process. Effectively the code is its own design document often." He quickly added, "For what it's worth, this is terrifying to me when I first joined as well."

New Wave of Data-Destroying Ransomware Attacks Hits QNAP NAS Devices (arstechnica.com) 23

Network hardware-maker QNAP is urging customers to update their network-attached storage devices immediately to protect them from a new wave of ongoing ransomware attacks that can destroy terabytes of data in a single stroke. From a report: Singapore-based QNAP said recently that it has identified a new campaign from a ransomware group known as DeadBolt. The attacks take aim at QNAP NAS devices that use a proprietary feature known as Photo Station. The advisory instructs customers to update their firmware, suggesting there is a vulnerability that's under exploit, but the company makes no explicit mention of a CVE designation that security professionals use to track such security flaws.

A Solar Firm's Plan to Build Off-Grid Neighborhoods in California (yahoo.com) 158

Sunnova is one of America's largest rooftop solar companies, according to the New York Times. But they've now applied to California's Public Utilities Commission for permission to become the state's first solar (and storage) micro-utility, initiating formal steps to qualify and "request a certificate to construct and operate microgrids," targetting new home developments that aren't yet connected to the grid.

"We see a future where communities, neighborhoods, and businesses can operate independently from the legacy grid with sustainable energy sources that provide uninterrupted power," says the company's founder and CEO. "We believe microgrids address a strong need in the market for more robust energy solutions and better connectivity...." But he's also offering touting another possible benefit: "relief that the existing transmission and distribution system will experience given that most of the power that will be consumed by these communities will be generated locally from renewable resources."

The company likes to point out that America's recently-passed climate bill included tax incentives to encourage microgrids. But the New York Times describes it as "a business model that is illegal in much of the United States." Sunnova said it would offer those residents electricity that was up to 20 percent cheaper than the rates charged by investor-owned utilities like Pacific Gas & Electric and Southern California Edison. If approved by regulators, the micro-utility model, also known as a microgrid, could undermine the growth of those larger utilities by depriving them access to new homes or forcing them to lower their rates to keep that business. Sunnova executives argue that the approach they are seeking approval for was authorized under a California law passed almost two decades ago for a resort just south of Lake Tahoe. In addition, the company says advances in solar and battery technology mean that neighborhoods can be designed to generate more than enough electricity to meet their own needs at a lower cost than relying on the grid.

"If they don't want to choose me, that should be their right; if they don't want to choose you, that should be their right, too," said John Berger, the chief executive of Sunnova.

A small number of homeowners have gone off the grid as the cost of solar panels and batteries has fallen. But doing so can be hard or impossible. Some local governments have rejected permits for off-grid homes on health and safety grounds, arguing that a connection to the grid is essential. But connecting a single home to the grid can cost tens or even hundreds of thousands of dollars, which means an off-grid system may actually be cheaper — especially for properties in remote areas, or in places where the local grid is at its capacity and would require significant upgrades to serve more homes. Off-grid setups can also be appealing because once a system is paid off, the cost of operating and maintaining it is often modest and predictable, whereas utility rates can move up sharply.... The nationwide average retail electricity rate increased 11 percent in June from a year earlier, according to the Energy Information Administration.

But the kind of micro-utilities that Sunnova hopes to create have also had problems. The utopian visions of generating electricity where it is used have often run into maintenance and other problems. Many tiny utilities created under such models in the United States and Canada were later swallowed up by larger power companies.... Sunnova's microgrid approach could suffer a similar fate. But the costs of solar panels and batteries have tumbled over the last decade, making the energy that off-grid systems generate much more affordable....

Utilities have been pressing regulators to reduce the compensation homeowners receive for the excess solar energy their rooftop systems send to the grid. The companies have argued that customers with solar panels are being offered generous credits for power that they are not contributing adequately toward the cost of maintaining power lines and other grid equipment....

Building and operating microgrids could provide a steady source of income to companies like Sunnova. That could essentially transform the rooftop solar companies into the kinds of utilities that they have long fought against.

Sunnova bills itself as an "Energy as a Service" company, and they expect their microgrids to experience 30 minutes or less of outages each year, the Times points out, "compared with an average of two hours a year at California's large investor-owned utilities."

In the article, the chief executive of home-building company Lennar says they've already formed a partnership with Sunnova. "We value the current electric grid and we're intrigued by new microgrid solutions that can supplement and support the traditional utility grid and help solve reliability during extreme weather and peak demand."

Underwater Datacenter Will Open For Business This Year (theregister.com) 71

A company called Subsea Cloud is planning to have a commercially available undersea datacenter operating off the coast of the US before the end of 2022, with other deployments planned for the Gulf of Mexico and the North Sea. The Register reports: Subsea, which says it has already deployed its technology with "a friendly government faction," plans to put its first commercial pod into the water before the end of this year near Port Angeles, Washington. The company claims that placing its datacenter modules underwater can reduce power consumption and carbon dioxide emissions by 40 percent, as well as lowering latency by allowing the datacenter to be located closer to metropolitan areas, many of which are located near the coast. However, according to Subsea founder Maxie Reynolds, it can also deploy 1MW of capacity for as much as 90 percent less cost than it takes to get 1MW up and running at a land-based facility.

The Port Angeles deployment, known as Jules Verne, will comprise one 20ft pod, which is similar in size and dimensions to a standard 20-foot shipping container (a TEU or Twenty-foot Equivalent Unit). Inside, there is space for about 16 datacenter racks accommodating about 800 servers, according to Subsea. Additional capacity, if and when required, is delivered by adding another pod. The pod-to-shore link in this deployment provides a 100Gbps connection. As it is a commercial deployment, Jules Verne will be open for any prospective clients or partners to come and check it out, virtually or otherwise, according to Reynolds. It will be sited in shallow water, visible from the port, whereas the Njord01 pod in the Gulf of Mexico and the Manannan pod in the North Sea are expected to be deeper, at 700-900ft and 600-700ft respectively.

The Subsea pods are kept cool by being immersed in water, which is one reason for the reduced power and CO2 emissions. Inside, the servers are also immersed in a dielectric coolant, which conducts heat but not electricity. However, the Subsea pods are designed to passively disperse the heat, rather than using pumps as is typical in submersion cooling in land-based datacenters. But what happens if something goes wrong, or a customer wants to replace their servers? According to Subsea, customers can schedule periodic maintenance, including server replacement, and the company says that would take 4-16 hours for a team to get to the site, bring up the required pod(s), and replace any equipment.

Major VPN Services Shut Down In India Over Anti-Privacy Law (9to5mac.com) 9

"Major VPN services have shut down service in India, as there is no way to comply with a new law without breaching their own privacy protection standards," reports 9to5Mac. "The law also applies to iCloud Private Relay, but Apple has not yet commented on its own plans." The Wall Street Journal reports: Major global providers of virtual private networks, which let internet users shield their identities online, are shutting down their servers in India to protest new government rules they say threaten their customers' privacy [...] Such rules are "typically introduced by authoritarian governments in order to gain more control over their citizens," said a spokeswoman for Nord Security, provider of NordVPN, which has stopped operating its servers in India. "If democracies follow the same path, it has the potential to affect people's privacy as well as their freedom of speech," she said [...]

Other VPN services that have stopped operating servers in India in recent months are some of the world's best known. They include U.S.-based Private Internet Access and IPVanish, Canada-based TunnelBear, British Virgin Islands-based ExpressVPN, and Lithuania-based Surfshark. ExpressVPN said it "refuses to participate in the Indian government's attempts to limit internet freedom." The government's move "severely undermines the online privacy of Indian residents," Private Internet Access said.
"Customers in India will be able to connect to VPN servers in other countries," adds 9to5Mac. "This is the same approach taken in Russia and China, where operating servers within those countries would require VPN companies to comply with similar legislation."

"Cloud storage services are also subjected to the new rules, though there would be little practical impact on Apple here. iCloud does not use end-to-end encryption, meaning that Apple holds a copy of your decryption key, and can therefore already comply with government demands for information."

One of World's Most Polluted Spots Gets Worse as $1 Billion Cleanup Drags On (bloomberg.com) 32

Mismanagement, waste and lack of transparency are making the cleanup in the Niger Delta's Ogoniland anything but exemplary, UN reports indicate. From a report: In the more than a quarter century since Shell Plc left Ogoniland in southern Nigeria, oil has continued to ooze from dormant wellheads and active pipelines, leaving the 386-square mile kingdom's wetlands shimmering with a greasy rainbow sheen, its once-lush mangroves coated in crude, well-water smelling of benzene and farmlands charred and barren. So when the $1 billion Ogoniland cleanup began in 2019, backed by Shell's funding pledge and support from the United Nations, it was heralded as the most ambitious initiative of its kind anywhere in the world. But now, UN Environmental Programme documents seen by Bloomberg and reported for the first time indicate that the project -- far from being exemplary -- is making one of the earth's most polluted regions even dirtier.

"We had hoped that the Ogoniland cleanup process would set the standard for the cleanup that will have to take place in the Niger Delta as a whole," said Mike Karikpo, an Ogoni attorney with Friends of the Earth International. "But we've not seen any impact. There ought to be some impact on the lives and livelihoods of people whose lands and rivers were impacted by this oil." In a scathing review of the Ogoniland cleanup efforts, led by the Hydrocarbon Pollution Remediation Project, or Hyprep, the UN body paints a picture of rampant mismanagement, incompetence, waste and lack of transparency. It highlights the haphazard storage of oil-soaked soil that lets chemicals seep into uncontaminated grounds and creeks, contracts awarded to firms with little environmental-cleanup experience and proposals for millions of dollars in unneeded work.

Japan Declares 'War' on the Humble Floppy Disk in New Digitization Push (bloomberg.com) 85

Japan's digital minister, who's vowed to rid the bureaucracy of outdated tools from the hanko stamp to the fax machine, has now declared "war" on a technology many haven't seen for decades -- the floppy disk. From a report: The hand-sized, square-shaped data storage item, along with similar devices including the CD or even lesser-known mini disk, are still required for some 1,900 government procedures and must go, digital minister Taro Kono wrote in a Twitter post Wednesday. "We will be reviewing these practices swiftly," Kono said in a press conference Tuesday, who added that Prime Minister Fumio Kishida has offered his full support. "Where does one even buy a floppy disk these days?" Japan isn't the only nation that has struggled to phase out the outdated technology -- the US Defense Department only announced in 2019 that it has ended the use of floppy disks, which were first developed in the 1960s, in a control system for its nuclear arsenal. Sony Group stopped making the disks in 2011 and many young people would struggle to describe how to use one or even identify one in the modern workplace.

Tesla Unveils New Virtual Power Plant In Japan (electrek.co) 34

Tesla has unveiled a new virtual power plant using Powerwalls home battery pack, and this time, it's on an island, Miyako-jima, in Japan. Electrek reports: A virtual power plant (VPP) consists of distributed energy storage systems, like Tesla Powerwalls, used in concert to provide grid services and avoid the use of polluting and expensive peaker power plants. Tesla launched one in California earlier this year, and it had its first emergency event earlier this month with great results. Now the company is trying to deploy a virtual power plant in Texas, and of course, it also had one in operation for years in Australia that is still expanding.

But now we have learned that Tesla also quietly built a new virtual power plant in Japan, and it has now decided to unveil it. The project is called "Miyakojima VPP" because it is located on the island of Miyako-jima, the most populous island in the Okinawa Prefecture. Tesla announced that it started to install Powerwalls in partnership with the local electric utility in 2021, and it now has over 300 Powerwalls on the island as part of the VPP. [...] Tesla explains that VPP is helping the island take better advantage of its renewable energy, but it is also proving more grid resilience, especially in the case of a natural disaster. The Miyakojima VPP is still growing, and Tesla expects that it will include 400 Powerwalls by the end of this year and 600 Powerwalls by the end of 2023. In 2024, Tesla expects to start installing Powerwalls for similar projects throughout the Okinawa Prefecture.
"[W]hen power supply and demand are tight on Miyako Island, electricity generated by photovoltaic power generation is stored in Powerwall before the tight time period and discharged from Powerwall to the home during the tight time period," said Tesla in a statement translated to Japanese. "It contributes not only to the households where the is installed, but also to the stabilization of Miyako Island's grid power supply, and stabilizes the power supply on the island. In addition, in the event of a power outage due to a typhoon, etc., power will be supplied from the Powerwall to the installed home, making it possible to prevent power outages in the home."

Microsoft Launches Arm-based Azure VMs Powered by Ampere Chips (techcrunch.com) 13

Following a preview in April, Microsoft this morning announced the general availability of virtual machines (VMs) on Azure featuring the Ampere Altra, a processor based on the Arm architecture. From a report: The first Azure VMs powered by Arm chips, Microsoft says that they're accessible in 10 Azure regions today and can be included in Kubernetes clusters managed using Azure Kubernetes Service beginning on September 1.

The Azure Arm-based VMs have up to 64 virtual CPU cores, 8 GB of memory per core and 40 Gbps of networking bandwidth as well as SSD local and attachable storage. Microsoft describes them as "engineered to efficiently run scale-out, cloud-native workloads," including open source databases, Java and .NET applications and gaming, web, app and media servers. Preview releases of Windows 11 Pro and Enterprise and Linux OS distributions including Canonical Ubuntu, Red Hat Enterprise Linux, SUSE Enterprise Linux, CentOS and Debian are available on the VMs day one, with support for Alma Linux and Rocky Linux to arrive in the future. Microsoft notes that Java apps in particular can run with few additional code changes, thanks to the company's contributions to the OpenJDK project.

Walmart Lists a 30TB Portable SSD for Just $39. It's a Scam (arstechnica.com) 122

What's the deal with that supposed 30TB external SSD being sold for just $31.40 on China-based online shopping site AliExpress? It's also listed on Walmart's website for just $39 — but first, listen to cybersecurity researcher calling himself "Ray [REDACTED]". Scammer gets two 512MB Flash drives. Or 1 gigabyte, or whatever. They then add hacked firmware that makes it misreport its size... when you go to WRITE a big file, hacked firmware simply writes all new data on top of old data, while keeping directory (with false info) intact.
Ars Technica goes over the details: On the inside, this "SSD" looks like two small-capacity microSD cards hot glued to a USB 2.0-capable board. This board's firmware has been modified so that each of these cards reports its capacity as "15.0TB" to the operating system, for a total of 30TB, even though the actual capacity of the cards is much lower.... It preserves the directory structure of whatever you're copying, but when it's "copying" your data, it just keeps writing and rewriting over the tiny microSD cards.

Everything will look fine until you go to access a file, only to find that the data isn't there.

Replies to Ray Redacted's thread are full of alternate versions of this scam, including multiple iterations of the hot-glued microSD version and at least one that hid a USB thumb drive inside a larger enclosure. Fake USB storage devices are neither new nor rare, though this one makes spectacularly egregious claims about its price-per-gigabyte. When it comes to buying storage online, common-sense advice is best: stick to name brands, buy from trustworthy sellers.... and know that if a deal seems too good to be true, it almost certainly is.

Pine64 Touts Its RISC-V-Based Single-Board Computer and Soldering Irons (pine64.org) 42

PINE64's August update included photos of their first prototype for its upcoming Star64 single-board computer, "the first true RISC-V single-board computer from us...but as I wrote last month it certainly isn't the last RISC-V piece of hardware you'll be seeing from us." Just as a short recap: Star64 comes with a StarFive JH7110 64bit CPU sporting quad SiFive FU740 cores clocked at 1.5GHz. The SOC is equipped with BXE-2-32 from Imagination Technologies, which is said to be a solid mid-range GPU. Star64 will be available in two configurations — with 4Gb and 8GB of RAM, similarly to the Quartz64. Both hardware versions include USB 3.0 and a PCIe slot as well as two native Gigabit Ethernet NICs.... Along the long leading edges you'll find PCIe on one end and GPIO on the other. At one end of the board you'll find a digital video output, a double-stacked Gigabit Ethernet port and a 12V barrel plug for power. On the opposite side, you'll find 3x USB 2.0, 1x USB 3.0, an audio jack as well as a power button. There are also two U.FL ports for antennas — one for bluetooth and the other for WiFi....

The Star64 also has an MiPi display output complete with a touch panel (TP) input, a 12V power port, a CSI camera port and an eMMC slot. A micro SD card slot can be found at the bottom of the PCB. Similarly to the RockPro64 and Quartz64, the 12V port on the Star64 can be used for powering other hardware directly from the board — a popular example is powering one or multiple SSDs connected to a PCIe SATA adapter. I'll add that, at least in theory, the Star64 would make a great network-attached storage device because of its SoCs low thermals and idle power. I am looking forward to seeing NAS-focused Linux or BSD* OSes available for the board.

Speaking of software, efforts to support the SoC in Linux have already begun. I've been told that both Debian and Fedora are already being ported to the StarFive JH7110, which is great news. We are certain that many other OSes will follow swiftly — especially once we start delivering the Star64 to interested developers. On the subject of availability: the Star64 will be available in a few weeks time, and will initially be available to developers. Given the interest in the Star64's and the SoC powering I hope to see functional distributions available for the board soon after launch.

The announcement also included an update on their PinecilV2 smart mini portable soldering iron (built with a 32-bit RISC-V SoC). "The Pinecil V2 landed earlier this month and sold out almost instantly. The next production run of the ought to be available soon however..."

Heroku Announces Plans To Eliminate Free Plans, Blaming 'Fraud and Abuse' (techcrunch.com) 9

After offering them for over a decade, Heroku announced this week that it will eliminate all of its free services -- pushing users to paid plans. From a report: Starting November 28, the Salesforce-owned cloud platform as a service will stop providing free product plans and shut down free data services and soon (on October 26) will begin deleting inactive accounts and associated storage for accounts that have been inactive for over a year. In a blog post, Bob Wise, Heroku general manager and Salesforce EVP, blamed "abuse" on the demise of the free services, which span the free plans for Heroku Dynos and Heroku Postgres as well as the free plan for Heroku Data for Redis.

[...] Wise went on to note that Heroku will be announcing a student program at Salesforce's upcoming Dreamforce conference in September, but the details remain a mystery at this point. For the uninitiated, Heroku allows programmers to build, run and scale apps across programming languages including Java, PHP, Scala and Go. Salesforce acquired the company for $212 million in 2010 and subsequently introduced support for Node.js and Clojure and Heroku for Facebook, a package to simplify the process of deploying Facebook apps on Heroku infrastructure. Heroku claims on its website that it's been used to develop 13 million apps to date.

According to a new paper published in the journal Nature, researchers at MIT describe new aluminum-sulfur batteries that are made entirely from abundant and inexpensive materials and can be charged in less than a minute. "The new battery architecture, which uses aluminum and sulfur as its two electrode materials, with a molten salt electrolyte in between, is described today in the journal Nature, in a paper by MIT Professor Donald Sadoway, along with 15 others at MIT and in China, Canada, Kentucky, and Tennessee," reports MIT News. The caveat with this new kind of battery is that it requires a variety of molten salts that need to be "close to the boiling point of water." From the report: In their experiments, the team showed that the battery cells could endure hundreds of cycles at exceptionally high charging rates, with a projected cost per cell of about one-sixth that of comparable lithium-ion cells. They showed that the charging rate was highly dependent on the working temperature, with 110 degrees Celsius (230 degrees Fahrenheit) showing 25 times faster rates than 25 C (77 F). Surprisingly, the molten salt the team chose as an electrolyte simply because of its low melting point turned out to have a fortuitous advantage. One of the biggest problems in battery reliability is the formation of dendrites, which are narrow spikes of metal that build up on one electrode and eventually grow across to contact the other electrode, causing a short-circuit and hampering efficiency. But this particular salt, it happens, is very good at preventing that malfunction. The chloro-aluminate salt they chose "essentially retired these runaway dendrites, while also allowing for very rapid charging," Sadoway says. "We did experiments at very high charging rates, charging in less than a minute, and we never lost cells due to dendrite shorting."

What's more, the battery requires no external heat source to maintain its operating temperature. The heat is naturally produced electrochemically by the charging and discharging of the battery. "As you charge, you generate heat, and that keeps the salt from freezing. And then, when you discharge, it also generates heat," Sadoway says. In a typical installation used for load-leveling at a solar generation facility, for example, "you'd store electricity when the sun is shining, and then you'd draw electricity after dark, and you'd do this every day. And that charge-idle-discharge-idle is enough to generate enough heat to keep the thing at temperature." This new battery formulation, he says, would be ideal for installations of about the size needed to power a single home or small to medium business, producing on the order of a few tens of kilowatt-hours of storage capacity.

For larger installations, up to utility scale of tens to hundreds of megawatt hours, other technologies might be more effective, including the liquid metal batteries Sadoway and his students developed several years ago and which formed the basis for a spinoff company called Ambri, which hopes to deliver its first products within the next year. For that invention, Sadoway was recently awarded this year's European Inventor Award. The smaller scale of the aluminum-sulfur batteries would also make them practical for uses such as electric vehicle charging stations, Sadoway says. He points out that when electric vehicles become common enough on the roads that several cars want to charge up at once, as happens today with gasoline fuel pumps, "if you try to do that with batteries and you want rapid charging, the amperages are just so high that we don't have that amount of amperage in the line that feeds the facility." So having a battery system such as this to store power and then release it quickly when needed could eliminate the need for installing expensive new power lines to serve these chargers.
"The first order of business for the company is to demonstrate that it works at scale," Sadoway says, and then subject it to a series of stress tests, including running through hundreds of charging cycles.

Apple Already Sold Everyone an iPhone. Now What? (economist.com) 113

The ubiquitous device is becoming a shop window for the firm's services. From a report: As it dreams up more gadgets to sell to more people, however, Apple is employing another strategy in parallel. The company has so far put 1.8bn devices in the pockets and on the desks of some of the world's most affluent consumers. Now it is selling access to those customers to other companies, and persuading those who own its devices to sign up to its own subscription services. As Luca Maestri, Apple's chief financial officer, said on a recent earnings call, the Apple devices in circulation represent "a big engine for our services business." The strategy is picking up speed. Last year services brought in $68bn in revenue, or 19% of Apple's total. That is double the share in 2015. In the latest quarter services' share was even higher, at 24%. Apple doesn't break down where the money comes from, but the biggest chunk is reckoned to be fees from its app store, which amounted to perhaps $25bn last year, according to Sensor Tower, a data provider.

The next-biggest part is probably the payment from Google for the right to be Apple devices' default search engine. This was $10bn in 2020; analysts believe the going rate now is nearer $20bn. Apple's fast-growing advertising business -- mainly selling search ads in its app store -- will bring in nearly $7bn this year, reckons eMarketer, another research firm. Most of the rest comes from a range of subscription services: iCloud storage, Apple Music and Apple Care insurance are probably the biggest, estimates Morgan Stanley, an investment bank. More recent ventures like Apple tv+, Apple Fitness, Apple Arcade and Apple Pay make up the rest. New services keep popping up. Last November Apple launched a subscription product for small companies called Apple Business Essentials, offering tech support, device management and so on. In June it announced a "buy now, pay later" service. The company claims a total of 860m active paid subscriptions, nearly a quarter more than it had a year ago.
