Semi-Trailer Trucks Test Converting Into Plug-In Hybrids

Long-time Slashdot reader necro81 writes: There are several companies, such as Tesla, trying to make semi trucks fully electric. The capital cost for such a truck, and the MW-scale infrastructure to recharge it, may be a hard sell for some operators. [IEEE Spectrum notes that's a charging infrastructure "that most freight corridors do not yet reliably provide."] But some companies are instead adding batteries and an electric motor to the semi-trailers that trucks haul behind them. "The Nivalis Powered Trailer Kit centers on an electric axle [rated at 50 kilowatts-peak]... capable of both propulsion assistance and regenerative braking. It draws on a 60-kilowatt-hour, 400-volt lithium-ion battery pack charged from three sources: the axle itself during braking and deceleration, a full-rooftop array of photovoltaic panels generating up to 3.7 kilowatts-peak, and a 32-amp, three-phase AC grid connection available during parking stops." This approach is more akin to a plug-in hybrid: the truck may still be diesel-powered, but the electric assist from the trailer allows the truck to run more efficiently. Replacing diesel with kWh can save operators money while also reducing emissions. This incremental approach may be more accessible and less capital-intensive than replacing the truck itself. From the article: The driver's only window into the system is a small display readable from the cab's side mirror that shows the system status and battery charge level. Nothing about the trailer's handling or licensing requirements changes. The partners project savings of up to 7,000 liters of diesel per trailer per year, which is enough to keep about 19 tonnes of carbon dioxide out of the air... Trailer Dynamics, an Aachen-based company, has conducted field tests with BMW Logistics, DB Schenker, Duvenbeck, and Volkswagen Konzernlogistik, reporting average fuel savings of around 40% for diesel tractor combinations, substantially higher than the up to 18% reduction implied by the Nivalis projection... Trailer Dynamics prices its system between €145,000 and €195,000 and targets a payback period of no more than five years. Nivalis targets five to six years at current costs.

'Billionaire Exodus? California Drew 10x More Venture Capital Than Any Other State This Year'

California drew more than $335 billion in venture capital funding this year, reports the Los Angeles Times, citing data released Thursday by PitchBook on private market funding: Its next biggest competitor, New York, raised less than a tenth of California's total. Texas raised 1/40th of the amount... Although a campaign for a new tax on billionaires has convinced some ultra-rich residents to shift to other states and businesses often complain that high property and energy costs and an anti-business regulatory regime make it too tough to make money in the state, the inability of the top talent, companies and investors in AI to set up elsewhere shows California's enduring attraction. The state's economy grew 5% last year to a record $4.25 trillion, making it larger than every country other than the U.S., China and Germany. It is home to nearly 400 billion-dollar startups - more than any other state, according to CB Insights... Among metropolitan regions, Los Angeles ranked behind only Silicon Valley and New York, which attracted $98 billion and $11.5 billion in venture investment, respectively... Investors poured in nearly $8 billion across 207 deals in the Los Angeles, Long Beach, and Santa Ana metro areas, up 28% from a year earlier, according to PitchBook... Nearly 90% of invested dollars [in California] went to AI firms, up from last year, when around 65% of new funds were allocated to AI. "If you're a tech company and you're not an AI company, you have a very, very difficult opportunity ahead of you to raise capital," Stanford said.

'Forget Coders. The Real AI Threat Is In the Back Office'

Which jobs are most threatened by AI? "Programmers, software engineers and other tech industry employees," goes one common answer. "But many economists are more concerned about a different, larger group of white-collar workers," reports the New York Times: customer service reps, bookkeepers, payroll clerks and HR specialists, "who fly under the radar but collectively account for tens of millions of jobs..." They are spread across the country and throughout the economy, working in every industry, in big cities and small towns, at major corporations and mom-and-pop businesses... These jobs typically offer a middle-class salary or a pathway to achieving one - much as manufacturing jobs did for men before decades of globalisation and automation wiped many of them away... For now, such an outcome is a fear, not a forecast. Despite high-profile layoffs in tech and finance, there is little firm evidence that AI has hurt the labour market as a whole. Economists have become increasingly convinced that disruptions are likely, but they say it is too early to know where or how widespread they will be. They remain broadly sceptical of claims that the technology will lead to mass unemployment in the near future. Some AI industry leaders have walked back such predictions in recent weeks. But given the extraordinary pace at which companies are adopting AI - and at which the technology is improving - economists say policymakers need to consider the potential effects on the labour market. And they say they are concerned that the public debate has focused too much on software engineers and a relative handful of other high-status careers - lawyers, consultants, economists - rather than the workers who could be most vulnerable... Economists at Northwestern University recently recalculated measures of AI exposure based on the makeup of the total workforce, not just the people using the technology. Administrative and front-line roles, such as customer service representatives, rose to the top of the list. "The most affected jobs are secretaries, are routine clerks," said Michelle Yin, one of the working paper's authors. "They're not computer scientists or data scientists at all." The article also includes this counterpoint from an economist at the University of Illinois who has studied earlier waves of white-collar automation: that like other disruptive technologies, AI likely will also create new jobs. So the possibility exists AI will make workers more productive and allow them to earn more. "I would be cautious about just focusing on what are we losing as opposed to what are we going to gain on the other side."

Apple sues OpenAI for theft of “trade secrets”

Apple sued OpenAI on Friday, alleging the AI company has stolen the iPhone maker's trade secrets to develop its own yet-to-be-unveiled AI gadgets. In the suit, filed in the District Court of Northern California, Apple accuses OpenAI of trade secret misappropriation and breach of contract. ↫ Lisa Eadicicco and Hadas Gold at CNN I find this about as interesting and watching artificial grass grow, but with the common wisdom being that Apple is behind on "AI", it was honestly only a matter of time before the lawsuits came. After all, that's usually what companies who can't win in the market do. At the very least this will give corporate tech news websites a whole slew of new material. I just hope they both implode. We'd all be better off for it.

Redox gets GTK3, Tcl

Redox did the develop cools stuff thing again for a month, so we've got progress to talk about. This past month, GTK3 has been ported to Redox, as well as the Tcl programming language. Support for per-window fractional scaling has been added to Orbital, Redox' desktop environment, but it's still relatively limited for now. There's also new USB gamepad support, which already works in quite a few emulators, as well as details about how Redox intends to improve its support for running in a virtual environment over the coming 12 months, an effort sponsored by NLnet. Of course, there's also the usual bugfixes and updates to various drivers, the kernel, Relibc, and more.

Understanding Windows monthly updates: Servicing explained

Windows has a fairly complex update ecosystem, so every now and then, the company feels like it needs to publish clarifications and explainers so people can keep up with what's going on. Most individuals and organizations regularly deploy monthly security updates, released on the second Tuesday of each month. Windows also provides optional non-security preview updates, which give IT teams and early adopters an opportunity to validate upcoming fixes before they're included in the next monthly security update. This guide explains the purpose of each update type, when updates are released, and how they fit into the modern Windows servicing model. ↫ Chris Morrissey at the Windows IT Pro Blog It's easy to make fun of Microsoft and Windows for just how complex and obtuse the update ecosystem really is, but in all honestly it's kind of understandable. Windows is a sprawling platform used by so many different people, companies, and organisations, under so many different circumstances and in so many different environments, it makes sense that Microsoft wants to address the multitude of needs that arise from that complexity. And so we end up not only with a dizzying array of update types and a long corpus of mystic terminology, but also a long list of complex different management tools to deploy said updates. And then there's the various preview channels making everything even more complex. I'm definitely not smart, qualified, or experienced enough to come up with a better solution, but I do think choosing better names for the various update types, and perhaps a centralised settings panel inside Windows that gave users a better idea of what each type of update actually does, would go a long way to improving clarity. During my month with Windows 11, I also found it deeply frustrating just how little information Microsoft provides about each of the updates Windows is installing. As a user, I was expected to copy/paste the KB number and then hope that would lead me to useful information, while it would be much more convenient if such information was available right then and there inside Windows Update. If you can't reduce complexity, you should try to improve transparency.
