Saturday the San Francisco Chronicle published a joint opinion piece from MIT professor Carlo Ratti (who directs an MIT digital lab exploring the collection of digital data about urban life) and John Rossant (founder of the collaborative data-sharing platform CoMotion).

Together they penned a warning about a future filled with robotaxis. "Their convenience could seduce us into vastly overusing our cars. The result? An artificial-intelligence-powered nightmare of traffic, technically perfect but awful for our cities." Why do we believe this? Because it has already come to pass with ride-sharing. In the 2010s, the Senseable City Lab at the Massachusetts Institute of Technology, where one of us serves as the director, was at the forefront of using Big Data to study how ride-hailing and ride-sharing could make our streets cleaner and more efficient. The findings appeared to be astonishing: With minimal delays to passengers, we could match riders and reduce the size of New York City taxi fleets by 40%. More people could get around in fewer cars for less money. We could reduce car ownership, and free up curbs and parking lots for new uses. This utopian vision was not only compelling but within reach.

After publishing our results, we started the first collaboration between MIT and Uber to research a then-new product: Uber Pool (now rebranded UberX Share), a service that allows riders to share cars when heading to similar destinations for a lower cost. Alas, there is no such thing as a free lunch. Our research was technically right, but we had not taken into account changes in human behavior. Cars are more convenient and comfortable than walking, buses and subways — and that is why they are so popular. Make them even cheaper through ride-sharing and people are coaxed away from those other forms of transit. This dynamic became clear in the data a few years later: On average, ride-hailing trips generated far more traffic and 69% more carbon dioxide than the trips they displaced. We were proud of our contribution to ride-sharing but dismayed to see the results of a 2018 study that found that Uber Pool was so cheap it increased overall city travel: For every mile of personal driving it removed, it added 2.6 miles of people who otherwise would have taken another mode of transportation.

As robotaxis are on the cusp of proliferating across the world, we are about to repeat the same mistake, but at a far greater scale... [W]e cannot let a shiny new piece of technology drive us into an epic traffic jam of our own making. The best way to make urban mobility accessible, efficient and green is not about new technologies — neither self-driving cars nor electric ones — but old ones. Buses, subways, bikes and our own two feet are cleaner, cheaper and more efficient than anything Silicon Valley has dreamt up... Autonomous technology could, for example, allow cities to offer more buses, shuttles and other forms of public transit around the clock. That's because the availability of on-demand AVs could assure "last-mile" connections between homes and transit stops. It could also be a godsend for older people and those with disabilities. However, any scale-up of AVs should be counterbalanced with investments in mass transit and improvements in walkability.

Above all, we must put in place smart regulatory and tax regimes that allow all sustainable mobility modes — including autonomous services — to scale safely and intelligently. They should include, for example, congestion fees to discourage overuse of individual vehicles.

When Linus Torvalds announced Linux kernel 6.6's first release candidate, it included a newly-stable version of KSMBD, which is Samsung's in-kernel server for the SMB protocol (for sharing files/folders/printers over a network).

An announcement in 2021 had said that "For many cases the current userspace server choices were suboptimal either due to memory footprint, performance or difficulty integrating well with advanced Linux features."

LWN noted at the time that Linux has been using "the user-space Samba solution since shortly after the beginning." In a sense, ksmbd is not meant to compete with Samba; indeed, it has been developed in cooperation with the Samba project. It is, however, meant to be a more performant and focused solution than Samba is; at this point, Samba includes a great deal of functionality beyond simple file serving. Ksmbd claims significant performance improvements on a wide range of benchmarks...One other reason — which tends to be spoken rather more quietly — is that a new implementation can be licensed under GPLv2, while Samba is GPLv3.
The Register notes that when Samba switched to GPL 3, "one result was that Apple dropped Samba from Mac OS X and replaced it with its own, in-house server called SMBX." And they also remember that a month after its debut in 2021, "Linux sysadmins got to enjoy KSMBD's first security exploit." What's changed now is that it has faced considerable security testing and as a result it is no longer marked as experimental. It's been developed with the assistance of the Samba team, which itself documents how to use it. It's compatible with existing Samba configuration files. As the team says, "It is not meant to replace the existing Samba fileserver 'smbd', but rather be an extension and will integrate with Samba in the future...."

KSMBD is also important in that placing such core server functionality right inside the kernel represents a significant potential attack surface for crackers... The new bcachefs file system will not be going into kernel 6.6, and its developer is not happy.
"It's taken some time to get KSMBD to a state that was considered stable," points out Linux magazine. That time has come, and KSMBD is planned for Linux kernel 6.6.: But why is KSMBD important? First off, it promises considerable performance gains and better support for modern features such as Remote Direct Memory Access (RDMA)... KSMBD also adds enhanced security, considerably better performance for both single and multi-thread read/write, better stability, and higher compatibility. In the end, hopefully, this KSMBD will also mean easier share setups in Linux without having to jump through the same hoops one must with the traditional Samba setup.

Slashdot reader quonset writes: Roblox Corporation was to have its award ceremony for developers on Saturday when it cancelled the event at the last moment. According to reports, a game developer was reportedly arrested on gun charges outside the event.
More from MarketWatch: Citing jail records, the San Francisco Chronicle reported Sunday that a man identified as game developer Mikhail Olson, known by the nickname Simbuilder, was arrested by U.S. Park Police on suspicion of having a concealed firearm in his vehicle, along with armor-piercing ammunition and a large-capacity magazine.

The awards ceremony was held at Fort Mason Center, which is on federal property. According to the Chronicle, the suspect was arrested Saturday afternoon after allegedly assaulting U.S. Park Police officers who had been called over a report of a disturbance outside the Roblox conference.

The financial services platform Square is experiencing a widespread outage, causing many small businesses around the country to switch to cash only. From a report: In a statement posted to their website, Square said it began investigating a service disruption linked to its data center at 11:47 a.m. As of 4:48 p.m., the San Francisco-based company said it was still working on a fix. Aaron Bergh, owner of Calwise Spirits Co. in Paso Robles, said he noticed the disruption around noon. In the three hours following, his business did about $1,000 in sales -- all without being able to process credit card payments.

Instead employees have been writing down credit card numbers to charge later or done business in cash, which has limited how much customers can spend, he said. In the five years he's been doing business, Bergh said he'd never experienced a Square outage lasting more than half-an-hour. Even in those cases, the platform would still allow businesses to record credit card information. This time, he can't even log into his account, he said. Square is posting updates at issquareup.com.

"Silicon Valley billionaires behind a secretive $800 million land-buying spree in Northern California have finally released some details about their plans for a new green city," reports the Associated Press, "but they still must win over skeptical voters and local leaders." After years of ducking scrutiny, Jan Sramek, the former Goldman Sachs trader spearheading the effort, launched a website Thursday about "California Forever." The site billed the project as "a chance for a new community, good paying local jobs, solar farms, and open space" in Solano, a rural county between San Francisco and Sacramento that is now home to 450,000 people. He also began meeting with key politicians representing the area who have been trying unsuccessfully for years to find out who was behind the mysterious Flannery Associates LLC as it bought up huge swaths of land, making it the largest single landholder in the county...

[T]o build anything resembling a city on what is now farmland, the group must first convince Solano County voters to approve a ballot initiative to allow for urban uses on that land, a protection that has been in place since 1984. Local and federal officials still have questions about the group's intentions... California is in dire need of more housing, especially affordable homes for teachers, firefighters, service and hospitality workers. But cities and counties can't figure out where to build as established neighborhoods argue against new homes that they say would congest their roads and spoil their quiet way of life.

In many ways, Solano County is ideal for development. It is 60 miles northeast of San Francisco and 35 miles southwest of California's capital city of Sacramento. Solano County homes are among the most affordable in the San Francisco Bay Area, with a median sales price of $600,000 last month. But Princess Washington, mayor pro tempore of Suisun City, said residents deliberately decided to protect open space and keep the area around Travis Air Force Base free of encroachment given its significance. She's suspicious that the group's real purpose is "to create a city for the elite" under the guise of more housing.
The web site for "California Forever" acknowledges they've purchased 50,000 acres — about 78 squares miles — "strategically located" in Northern California's Solano County with access to water and low fire risk.

Speculative illustrations on the site "evoke a cityscape with a dreamy white stucco and red rooftop Mediterranean vibe that might be found in a Greek or Italian village," writes the San Francisco Chronicle. There are hillside neighborhoods stepping down to what must be the banks of the Sacramento River, kayakers tooling through lily pads and anglers fishing from the riverbank at sunrise... The website also names an investor who has not been named previously — venture capitalist John Doerr of Kleiner Perkins, an early investor in Google, Slack and other companies...

While California Forever may have billions to invest in the project, it will face staunch opposition from some ranchers who argue that the city would disrupt the economy of a county that is 62% farmland.
The San Francisco Chronicle's urban design critic writes "OK, this is something new — an elevator pitch for a whole new city..." But the website launched Thursday by California Forever offers no real details, such as the projected population or precise location. Instead, there are renderings of cuddly townscapes and soothing talk of building "a remarkable place for Solano residents." Oh, and an earnest promise to "begin the phase of our work that matters most: our conversation with you." Let the eye-rolling commence. It's impossible to critique the vision of the investors, because what was unfurled is so innocuous as to be an insult...

The website also refers to how this will be a center of "economic opportunity" and "new employers." Great! But only two of the 12 renderings show people at work, including one where three men install solar panels while the sun sets in the west. Let's hope they're being paid overtime... The Bay Area needs housing and jobs. It also needs honest approaches to making this happen. Let's hope when California Forever 2.0 launches, there is less fluff and more facts.

"Two stalled driverless taxis blocked an ambulance carrying a critically injured patient," writes the San Francisco Chronicle, citing a paywalled report from Forbes. The delay "contributed to 'poor patient outcome' — the person died 20 to 30 minutes after reaching the hospital, according to a report by San Francisco firefighters that the taxi company disputes."

The report was obtained by Forbes, which recently published a story detailing accounts by San Francisco firefighters who say driverless taxis have repeatedly interfered with their emergency response. However, Forbes also reported that Cruise provided a video that disputed SFFD's account of the August 14 incident. The video, Forbes reported, shows that one Cruise car quickly left the scene while the other remained stalled at the intersection with an open lane to its right, which traffic was passing through. Forbes said it was not clear from the video if the ambulance could have navigated into the open lane.

Hannah Lindow, a Cruise spokesperson, told the Chronicle that the Cruise vehicle that stopped did so to yield to first responders directing traffic. "Throughout the entire duration the (autonomous vehicle) is stopped, traffic remains unblocked and flowing to the right of the AV. The ambulance behind the AV had a clear path to pass the AV as other vehicles, including another ambulance, proceeded to do," Lindow said in an email. "As soon as the victim was loaded into the ambulance, the ambulance left the scene immediately and was never impeded from doing so by the AV."

An anonymous reader shared this report from the New York: In 2017, Michael Moritz, a billionaire venture capitalist, sent a note to a potential investor about what he described as an unusual opportunity: a chance to invest in the creation of a new California city. The site was in a corner of the San Francisco Bay Area where land was cheap. Moritz and others had dreams of transforming tens of thousands of acres into a bustling metropolis that, according to the pitch, could generate thousands of jobs and be as walkable as Paris or the West Village in New York.

He painted a kind of urban blank slate where everything from design to construction methods and new forms of governance could be rethought. And it would all be a short distance from San Francisco and Silicon Valley... Since then, a company called Flannery Associates has been buying large plots of land in a largely agricultural region 60 miles northeast of San Francisco. The company, which has little information public about its operations, has committed more than $800 million to secure thousands of acres of farmland, court documents show. One parcel after another, Flannery made offers to every landowner for miles, paying several times the market rate, whether the land had been listed for sale or not...

Brian Brokaw, a representative for the investor group, said in a statement that the group was made up of "Californians who believe that Solano County's and California's best days are ahead." He said the group planned to start working with Solano County residents and elected officials, as well as with Travis Air Force Base, next week... The land that Flannery has been purchasing is not zoned for residential use, and even in his 2017 pitch, Moritz acknowledged that rezoning could "clearly be challenging" — a nod to California's notoriously difficult and litigious development process. To pull off the project, the company will almost certainly have to use the state's initiative system to get Solano County residents to vote on it. The hope is that voters will be enticed by promises of thousands of local jobs; increased tax revenue; and investments in infrastructure like parks, a performing arts center, shopping, dining and a trade school.
Moritz's 2017 email had argued their project "should relieve some of the Silicon Valley pressures we all feel — rising home prices, homelessness, congestion etc."

SFGate estimates the group now owns 52,000 acres — "an empire that is nearly double the size of the city of San Francisco" — and notes that some details emerged when the group filed a document to repond to a lawsuit. "It claims it told landowners that they could keep 'existing income streams from wind energy and natural gas storage,' could 'continue using these properties rent-free for decades,' and would receive 'significant grants from Flannery for charitable giving, to be used at the [landowners'] discretion to support local schools and other non-profits.'"

"Tech billionaires reportedly backing mysterious Solano County land grab," reads the headline on SFGate's latest article: SFGATE reported earlier this week that a survey had circulated to Solano County residents asking for their opinions on the potential development of "a new city with tens of thousands of new homes, a large solar energy farm, orchards with over a million new trees, and over ten thousand acres of new parks and open space."

Meta, intent on making a splash in a generative AI space rife with competition, is on something of an open source tear. From a report: Following the release of AI models for generating text, translating languages and creating audio, the company today open sourced Code Llama, a machine learning system that can generate and explain code in natural language -- specifically English. Akin to GitHub Copilot and Amazon CodeWhisperer, as well as open source AI-powered code generators like StarCoder, StableCode and PolyCoder, Code Llama can complete code and debug existing code across a range of programming languages, including Python, C++, Java, PHP, Typescript, C# and Bash.

"At Meta, we believe that AI models, but large language models for coding in particular, benefit most from an open approach, both in terms of innovation and safety," Meta wrote in a blog post shared with TechCrunch. "Publicly available, code-specific models can facilitate the development of new technologies that improve peoples' lives. By releasing code models like Code Llama, the entire community can evaluate their capabilities, identify issues and fix vulnerabilities." Code Llama, which is available in several flavors, including a version optimized for Python and a version fine-tuned to understand instructions (e.g. "Write me a function that outputs the fibonacci sequence"), is based on the Llama 2 text-generating model that Meta open sourced earlier this month. While Llama 2 could generate code, it wasn't necessarily good code -- certainly not up to the quality a purpose-built model like Copilot could produce.

In a Thursday memo, Meta's "Head of People" told employees "that their managers would receive their badge data and that repeated violations of the new three-day-a-week requirement could cause workers to lose their jobs," writes SFGate (citing a report from Insider): In June, the Menlo Park-based firm announced its plan to require that most employees work from an office at least three days each week — it goes into effect Sept. 5... Meta confirmed the update to SFGATE... Goler's note on the return-to-office requirements, Insider reports, reads, "As with other company policies, repeated violations may result in disciplinary action, up to and including a Performance rating drop and, ultimately, termination if not addressed."

As for employees who are grandfathered into a remote work arrangement (the firm bars managers from opening more of these positions), the note lays down a strict policy: If remote employees consistently come into the office more than four times every two months outside major events, they'll be shifted to the three-day-a-week plan.

"We believe that distributed work will continue to be important in the future, particularly as our technology improves," a Meta spokesperson said in a statement sent to SFGATE. "In the near-term, our in-person focus is designed to support a strong, valuable experience for our people who have chosen to work from the office, and we're being thoughtful and intentional about where we invest in remote work."
The article notes that Mark Zuckerberg told The Verge in 2020 that Meta would become "the most forward-leaning company on remote work at our scale," speculating that half the company could be permanently remote within a decade.

"However, in 2023, which Zuckerberg dubbed Meta's 'year of efficiency,' employees have seen a remote-first culture melt away. In March, as the executive announced 10,000 layoffs on top of a huge cut in November, he wrote that early-career engineers do better when they're working in person at least three days a week."

Thursday a Cruise robotaxi drove through a green light in front of an oncoming firetruck "with its forward facing red lights and siren on, the San Francisco Police Department said in a statement to Reuters." The San Francisco Chronicle adds that the Cruise vehicle's passenger "passenger was treated on the scene and shared taken in an ambulance to a hospital, though the company said the injuries were 'non-severe.' The company added in an email to the Chronicle that the passenger was on the scene walking around and talking to emergency responders before being taken to the hospital."

By Friday California's Department of Motor Vehicles said it was investigating the "concerning incidents," according to TechCrunch. But it adds that the AV-regulating agency also "called for Cruise to reduce its fleet by 50% and have no more than 50 driverless vehicles in operation during the day and 150 driverless vehicles in operation at night until the investigation is complete. Cruise told TechCrunch it is complying with the request. Cruise also issued a blog post giving the company's perspective of how and why the crash occurred.
Cruise's blog post points out the firetruck was unexpectedly in the oncoming lane of traffic that night. But meanwhile, elsewhere in the city... The same night, a Cruise car collided with another vehicle at 26th and Mission streets. The company said another driverless car, which had no passengers, entered the intersection on a green light when another car ran a red light at high speed. The driverless car detected the other car and braked, according to Cruise, but the two cars still collided...

The collisions came a day after city officials asked state regulators to halt their approval of robotaxi companies' unrestricted commercial expansion in the city, citing concerns about how the robotaxis' behavior impacts emergency responders.
Last weekend Cruise was also criticized after "as many as 10 Cruise driverless taxis blocked two narrow streets," reports the Los Angeles Times: Human-driven cars sat stuck behind and in between the robotaxis, which might as well have been boulders: no one knew how to move them.... The cars sat motionless with parking lights flashing for 15 minutes, then woke up and moved on, witnesses said.
Cruise "blamed cellphone carriers for the problem," according to the article — arguing that a music festival overloaded the cellphone network they used to communicate with their vehicles.

An anonymous reader quotes a report from The Guardian: In May, the World Health Organization issued an alarming report that declared widely used non-sugar sweeteners like aspartame are likely ineffective for weight loss, and long term consumption may increase the risk of diabetes, cardiovascular diseases and mortality in adults. A few months later, WHO declared aspartame, a key ingredient in Diet Coke, to be a "possible carcinogen," then quickly issued a third report that seemed to contradict its previous findings -- people could continue consuming the product at levels determined to be safe decades ago, before new science cited by WHO raised health concerns. That contradiction stems from beverage industry corruption of the review process by consultants tied to an alleged Coca-Cola front group, the public health advocacy group US Right-To-Know said in a recent report.

It uncovered eight WHO panelists involved with assessing safe levels of aspartame consumption who are beverage industry consultants who currently or previously worked with the alleged Coke front group, International Life Sciences Institute (Ilsi). Their involvement in developing intake guidelines represents "an obvious conflict of interest", said Gary Ruskin, US Right-To-Know's executive director. "Because of this conflict of interest, [the daily intake] conclusions about aspartame are not credible, and the public should not rely on them," he added. [...] Ilsi describes itself as a nonprofit that conducts "science for the public good", but it was founded in 1978 by a Coca-Cola executive who simultaneously worked for the company through 2021, US Right-To-Know found. Other Coca-Cola executives have worked with the group, and US Right-To-Know detailed tax returns that show millions in donations from Coca-Cola and other beverage industry players. Coke ended its official membership with the group in 2021.

Over the years, Ilsi representatives have sought to shape food policy worldwide, and Ruskin, who has written multiple peer-reviewed papers on the group, characterized the aspartame controversy as a "masterpiece in how Ilsi worms its way into these regulatory processes." US Right To Know identified six out of 13 Jefca panel members with ties to the industry group. After it released its report, the WHO acknowledged two more of its members with industry ties. In a statement to the Guardian, a WHO spokesperson defended the industry consultants' inclusion in the review process. "For the meeting on aspartame, Jefca selected the experts likely to make the best contributions to the debate," said spokesperson Fadela Chaib. She said WHO's guidelines only require disclosure of conflicts of interest within the last four years. "To our knowledge, the experts you listed by name have not participated in any Ilsi activities for at least 10 years," she said. But that partially contradicts a statement made by WHO just weeks before to the news outlet Le Parisien in which it acknowledged two people currently working with Ilsi were involved in the process. The Guardian had also asked about those two people identified in the Parisien story but were not listed "by name" in its email. The WHO told Le Parisien: "We regret that this interest was not declared by these two experts either in the written statement or orally at the opening of the meeting."

A new analysis "shows that over 4,000 gigawatts (GW) of offshore wind potential is available along the U.S. coastline," capable of fulfilling up to 25% of U.S. energy demand in 2050. (And it could also add $1.8 trillion in economy-boosting investment, while employing up to 390,000 workers.)

This new analysis comes from Berkeley researchers, who worked with nonprofit clean energy research firm GridLab and climate policy think tank Energy Innovation, reports the Verge: The Biden administration has committed to halving the nation's emissions by the end of the decade and has plans to source electricity completely from carbon pollution-free energy by 2035. Adding to that urgency, U.S. electricity demand is forecast to nearly triple by 2050, according to the Berkeley report. On top of a growing economy, the clean energy transition means electrifying more vehicles and homes — all of which put more stress on the power grid unless more power supply comes online at a similar pace.

To meet that demand and hit its climate goals, the report says the U.S. has to add 27 gigawatts of offshore wind and 85 GW of land-based wind and solar each year between 2035 and 2050. That timeline might still seem far away, but it's a big escalation of the Biden administration's current goal of deploying 30 GW of offshore wind by 2030. Europe, with an electricity grid about 70% the size of the U.S., already has about as much offshore wind capacity as the Biden administration hopes to build up by the end of the decade. Right now, wind energy makes up just over 10% of the U.S. electricity mix, and nearly all of that comes from land-based turbines...

For now, the U.S. has just two small wind farms off the coasts of Rhode Island and Virginia. Construction started on the foundations for the nation's first commercial-scale wind farm off Martha's Vineyard, Massachusetts, in June... Project costs have gone up with higher interest rates and rising prices for key commodities like steel, Heatmap reports. That's led to power purchase agreements falling through for some projects in early development, including plans in Rhode Island for an 884-megawatt wind farm that alone would have added more than 20 times as much generation capacity as the U.S. has today from offshore wind. Developers are struggling to make projects profitable without passing costs on to consumers...

The study found a modest 2 to 3 percent increase in wholesale electricity costs with ambitious renewable energy deployment. But renewable energy costs have fallen so dramatically in the past that the researchers think those costs could wind up being smaller over time.
The report points out that wind energy complements solar, by producing the most wind energy right when demand is peaking (in the summertime on the West Coast, and during the winter on the East Coast).

Bram Moolenaar was Vim's creator/maintainer/benevolent-dictator for life. Early this morning his family shared sad news on the Vim-announce Google Group. "It is with a heavy heart that we have to inform you that Bram Moolenaar passed away on 3 August 2023." Moolenaar was 62 years old, and died from "a medical condition that progressed quickly over the last few weeks."

"Bram dedicated a large part of his life to VIM and he was very proud of the VIM community that you are all part of."

Anyone who's used Vim has seen evidence of Moolenaar's generosity. "Vim is Charityware," Moolenaar wrote in its pioneering license. "You can use and copy it as much as you like, but you are encouraged to make a donation for needy children in Uganda." Moolenaar pioneered the concept of charityware decades ago, and also helped to popularize its adoption. To this day Vim users can still view the license by typing the command :help Uganda or :help ICCF. And Vim's sponsor FAQ notes that "Each registered Vim user and sponsor who donates at least 10 euro will be able to vote for new features."

Moolenaar's personal web site also includes photos from his travels around the world, and YouTube has some videos of talks and interviews with Moolenaar.

He was still committing changes to Vim up until a month ago.

In the comments below long-time Slashdot reader bads shares a link to a post from long-time Vim contributor Christian Brabandt : Bram was a great leader to the Vim community and I really enjoyed working with him over the past years, since I became involved with the development of Vim almost 20 years ago.

Bram was of great inspiration in creating a great community, helping people with his charity and he was a great mentor. And now he left too soon. We lost a great leader and I regret never having met him in person.

However to all of the community: I will continue and I hope all of the other contributors will also keep up the good work. I do have access to the Vim homepage and the Vim organization (not sure if all the rights, but I am sure we will work on the details in the near future...) I hope together we will be able to continue successfully.

Capella Space's synthetic aperture radar satellites are falling back to Earth much sooner than than the three years they were anticipated to operate, according to publicly available satellite data. TechCrunch reports: The startup has launched a total of ten small satellites to low Earth orbit since 2018, including eight in its family of "Whitney"-class spacecraft. Five of these satellites have reentered the atmosphere since the end of January of this year, including three of the Whitneys. Those Whitney sats were in orbit for less than two-and-a-half years; one, Capella-5, was in orbit for less than two years. That leaves five of the constellation in orbit, including the Capella-9 and Capella-10 launched on March 16, which are operating at an altitude of around 584 km and 588 km, respectively.

According to filings with the Federal Communication Commission, the propulsion system of Capella-9 was built by Phase Four. At least one of the satellites that has reentered prematurely, Capella-5, also used Phase Four propulsion. In that same filing from March 2022, Capella said its Capella-9 satellite would operate at an orbital altitude of 525 km, and maintain an altitude between 475-575 km for three years. It seems this is the typical mission profile of Capella satellites. But Capella-7 and Capella-8, launched in January 2022, appear to be now operating below 400 kilometers, and will likely deorbit in a matter of weeks to a few months. The unexpected decay could be due to a problem with the propulsion system, or a systematic miscalculation of its requirements.

"Probably they [Capella-7 and Capella-8] will reenter in Sep-Oct or so," astronomer and analyst Jonathan McDowell said when reviewing the data at TechCrunch's request. "I suspect propulsion failures but certainly it isn't clear." In a statement to TechCrunch, Capella CEO Payam Banazadeh confirmed that some of the satellites have been deorbiting faster than expected "due to the combination of increased drag due to much higher solar activity than predicted by NOAA and less than expected performance from our 3rd party propulsion system." "We have upgraded our propulsion system on all future satellites to account for these facts, including the launch of our next generation satellite Acadia-1, currently scheduled for launch on August 5th 2023. We plan to launch eight of our next generation Acadia satellites over the next 12 months," he added.

An anonymous reader shares this report from Dice.com: C++ is enjoying a surge in popularity, according to the latest update to the TIOBE Index, which tracks programming languages' "buzz."

C++ currently sits right behind C and Python on TIOBE's list. "A few months ago, the programming C++ language claimed position 3 of the TIOBE index (at the expense of Java). But C++ has not finished its rise. C seems to be its next victim," added the note accompanying the data... ["At the moment, the gap between the two is only 0.76%."]

Matlab, Scratch and Rust also match their all time high records at respectively positions #10, #12 and #17.
So here, according to TIOBE, are the 10 most popular programmings languages:

1. Python
2. C
3. C++
4. Java
5. C#
6. JavaScript
7. Visual Basic
8. SQL
9. PHP
10. MATLAB

The site I Programmer digs deeper: C++ was the only one of the top four languages to see a positive year-on-year change in its percentage rating — adding 0.79% to stand at 10.8%. Python had the smallest loss of the entire Top 20, -0.01% leaving it with a share of 13,42% while Visual Basic had the greatest loss at -2.07%. This, combined with JavaScript gaining 1.34%, led to JavaScript overtaking it to occupy #6, its highest ever ranking in the TIOBE Index.
They also note that COBOL "had a 3-month rise going from a share of 0.41% in April to 0.86% in July which moved it into #20 on the index."

An anonymous reader shared this report from Axios: Over 20% of the U.S.' population — 80 million people — are expected to face an air temperature or heat index above 105 degrees Fahrenheit this weekend as a record-breaking heat wave persists over most of the South, the National Weather Service (NWS) warns...

The extreme temperatures, which have been exacerbated by human-caused climate change, will come after several days of excessive heat and will be an immediate risk to public health... Heat index is what the temperature feels like to the human body when relative humidity is combined with the air temperature, and indices 103 degreesF or above can lead to dangerous heat disorders.

"Dozens" of temperature records could break across the Southern U.S., including overnight highs, the NWS said... About 115 million people in over a dozen states from California to Florida were under heat alerts on Thursday morning... The threatening heat is forecast to continue over the Southwest through "at least" July 28 and may expand into other parts of the country...

Global temperatures are hitting unprecedented highs, too, this year amid climate change and global warming. Elevated temperatures are also contributing to Canada's worst fire season on record, in which at least 27.1 million acres have burned across the country so far.
On Wednesday the city of Phoenix, Arizona — population 1.6 million — "experienced its 20th straight day with a temperature of over 110 degreesF," the article points out. And meanwhile Austin Texas (population 960,000) "saw its 10th straight day of temperatures at or above 105 degreesF for the first time in recorded history."

The National Weather Service's advice? "Take the heat seriously and avoid extended time outdoors."

This week the Slackware Linux project is celebrating its 30th anniversary. It is the oldest Linux distribution that is still in active maintenance and development. The Register reports: Version 1.0 of Slackware was announced on the July 16, 1993, and project lead Patrick Volkerding, who still maintains the distribution today, celebrated with a modest announcement: "Hey folks! It's time to acknowledge another one of those milestones... 30 (!) years since I made the post linked below announcing Slackware's first stable release after months of beta testing. Thanks to all of our dedicated contributors, loyal users, and those who have helped us to keep the lights on here. It's really been a remarkable journey that I couldn't have anticipated starting out back in 1993. Cheers! :-)"

After a severe rainstorm, two Cruise robotaxis drove past several downed trees and power lines, and then through caution tape, reports the San Francisco Chronicle. And then one of the Cruise vehicles caught on a low-hanging power wire for the city's bus system, "dragging it upward the rest of the block."

The article notes that the transit agency "had already de-energized the lines by the time the Cruise taxi hit them." But the cars only stopped "after driving through another set of caution tape and sandwich boards." Cruise personnel who retrieved the entangled car had to manually back it up a half block "to release the tension on the wire," according to a San Francisco Fire Department report. No one was inside the cars at the time, and no one was hurt...

But for city officials who oppose the rapid expansion of driverless taxi companies Cruise and Waymo, the episode reflects a recent and troubling trend. As driverless taxis ramp up operations in San Francisco, their disruption and close calls have increased in frequency and severity as well, officials say. "It really, really concerns me that something is going to go horribly wrong," Fire Chief Jeanine Nicholson said.

Cruise and Waymo say city officials have mischaracterized their safety track records. Their driverless taxis, the companies say, have lower collision rates than human drivers and public transit. Their self-driving cars, they argue, help improve traffic safety in San Francisco because their cars are programmed to follow posted speed limits.

The Fire Department has tallied 44 incidents so far this year in which robotaxis entered active fire scenes, ran over fire hoses or blocked fire trucks from responding to emergency calls. That count is double the figure from last year's informal count, which Nicholson said does not include all incidents.
Meanwhile the city's transit agency tallied 96 incidents just in March "where driverless cars disrupt traffic, transit and emergency responders," according to the article — and then another 91 in April.

But the issue is drawing more attention now because next month California's state regulatory agency and DMV "will vote on whether to allow Cruise and Waymo to charge for rides at all hours with no restrictions."

Evernote, the note-taking and task management application, is triggering fears of closure after its parent company Bending Spoon laid off most of the company's staff and announced plans to relocate all operations to Europe. Thurrott reports: Most of the company's "operations will be transitioned to Europe," Bending Spoons CEO Luca Ferrari told SFGate, due to the "significant boost in operational efficiency that will come as a consequence of centralizing operations in Europe." As a result, most of Evernote's staff in the San Francisco Bay area and Chile has been laid off and those offices will be closed for good.

Bending Spoons won't confirm how many Evernote employees it laid off, but Ferrari claims all is well. "Our plans for Evernote are as ambitious as ever," he said. "Going forward, a growing, dedicated team based in Europe will continue to assume ownership of the Evernote product. This team will also be in an ideal position to leverage the extensive expertise and strength of the 400-plus workforce at Bending Spoons, many of whom have been working on Evernote full-time since the acquisition." Paul Thurrott notes that Bending Spoons announced plans to acquire Evernote in November 2022. "At the time of the announcement, Mr. Ferrari said that he 'saw the potential' in Evernote, which has struggled in recent years after being a Silicon Valley startup darling a decade or more ago."
