Arthur T Knackerbracket has processed the following story:

While CTO officially stands for Chief Technology Officer, the standard jokes are that it’s either Chief Talking Officer or Chief Travel Officer. I embraced all of those roles, especially the travel part when my territory covered India, New Zealand, China and everything in between. And while I definitely relished having a job that required me to keep developing my expertise in a wide range of technical fields, I also really enjoyed the chance to keep working on my communications skills, whether that was through talking or writing.

In my last year at VMware (when travel was curtailed due to COVID) I put a lot of energy into developing (online) presentations, including one on the art of giving presentations. You can find that talk on Peertube – it is in PechaKucha format, which means 20 slides, 20 seconds per slide, which I find a great source of creative inspiration. You can probably watch it in less time than it takes to read this article.

The longer I worked in technology, the more I came to believe that communications, both oral and written, can be a key differentiator in a technical career. Probably the first time I realized this was when writing my PhD thesis. Engineers as a group are notoriously averse to writing, but I came to see the satisfaction to be had in clearly communicating your ideas on paper. For one thing, by the time I was in the last year of my program, I was pretty happy to be producing something as tangible as a thesis. I had written a lot less software in my course than I’d expected, a result of Edinburgh Computer Science being more of a theory place than one encouraging system building from its students. So watching my ideas grow on the page into something the size of a book was oddly satisfying.

I think the reason I was not as averse to writing as many engineers had a lot to do with the way I was educated in Australia. High school English was a “must-pass” subject if you wanted to go on to university, and I found it much more challenging than my maths and science classes. Not wanting to take chances, I worked disproportionately hard on English in my last year of high school, surprising both myself and my teachers with the highest grade of my life in the final exam that mattered most.

Somewhat to my chagrin, the undergraduate engineering degree in those days did not allow any courses to be taken outside of the Engineering department, but there was a mandated “English for Engineers” course, taught by one of the engineering lecturers. (I think the course had a different official name, something like “Engineering Communications”.) I can only remember two things about that course: one is that we read “Voss” by Nobel-prize-winner Patrick White, which was challenging but enjoyable. So they weren’t treating us as complete dummies. And the second was that we had to make a formal presentation in front of the class, which I found both stressful and educational. (My high school debating experience helped a bit here.) While I might have enjoyed an actual English Literature class more, this one was much better than the course name implied.

I continued to make the occasional presentations through my PhD program and into my early career, but a pivotal experience was watching David Clark speak twice at SIGCOMM 1990, at which he won the SIGCOMM award and also presented the paper, "Architectural considerations for a new generation of protocols.” His presentation of the latter was so engaging that I remember thinking “that is how you get people to listen to your ideas.” (That paper’s ideas continue to influence my thinking today.) As a young researcher at Bellcore at the time, I was surrounded by people who had creative ideas, but I had never seen someone get the audience excited about their work the way Clark had done. I resolved to get better at making technical presentations.

At the same time, I was working on my “accidental smartNIC” project as part of the Aurora gigabit testbed. There came a point where I realized that the system was complex enough that I needed to write some sort of design document–hardly a revolutionary idea in industry, but somewhat uncommon in the research group that I worked in. My first audience for this document was me, because I realized I couldn’t keep all the details in my head any more. Later on it would enable me to involve others in the project both as subsystem designers and programmers of the system.

When I left the research world for a development team at Cisco, I quickly noticed that there was a massive repository of system design documents. There were the formal ones such as product requirements documents (PRDs) and system functional specifications, but also less formal documents, such as Yakov Rekhter’s famous two-page description of Tag Switching that laid the foundation for MPLS. While Cisco was a place that put a lot of emphasis on building hardware and writing the software to run on it, documenting ideas and architectures was critical to getting big things like MPLS to happen.

Coincidentally, the first book that Larry and I wrote together, Computer Networks: A Systems Approach, was completed on the day that I decided to leave Bellcore for Cisco. I realized that completing the book – which was not part of my job description at Bellcore – was the most satisfying thing I had done in years, so maybe it was time for a new job.

By this time I was also active in the IETF, and the development of Tag Switching and MPLS led to my taking a more active role there. There are pretty much two ways to have an impact at the IETF: Write documents, and speak about your work. Of course, the IETF also depends on “running code” to back up those documents and talks – a definite benefit of working at a big place like Cisco was the resources that could be applied to writing code if the company decided to get behind an idea, as it did with MPLS.

All of these experiences led me to appreciate the value of both written and spoken communication, and I continued to work on developing these skills. Taking a couple of public speaking classes early on had a huge positive impact – although I still talk too fast when I get excited about my topic. (I’ve learned skills to manage that, but sometimes forget them in the excitement.)

Learning to be a good communicator can itself be a great way to build your technical skills

In my CTO roles I had plenty of opportunities to advise engineers on how to progress their careers, and I always found myself coming back to emphasize the value of communication skills. Of course you need technical skills as well, but I view these as table stakes, whereas it is the great communicators who rise above the pack. And communication skills are eminently trainable. All the great public speakers I know put huge amounts of time into preparing and practicing their talks. They might look effortless on stage, but that is because of all the effort that went in ahead of time.

Finally, learning to be a good communicator can itself be a great way to build your technical skills. In my last year at VMware, I started to get really interested in quantum computing, which was a challenge for me – it’s full of mathematics and outside my core expertise. But the more I learned the more excited I got, so I decided to present on quantum computing at our Asia-Pacific technical team conference. My goal was both to become knowledgeable enough to avoid embarrassing myself, and to show by example how much fun it can be to expand your horizons.

A version of the talk is here and some lessons from it are here. If you can learn a topic well enough to explain it to your audience, you are going to have a deeper understanding than if you just keep that knowledge to yourself. And if you can communicate your ideas–and your excitement about them–to people around you, you’ll greatly increase the chance of those ideas having an impact.

"The European Union, which was formed for the primary purpose of taking advantage of the United States on TRADE, has been very difficult to deal with. Their powerful Trade Barriers, Vat Taxes, ridiculous Corporate Penalties, Non-Monetary Trade Barriers, Monetary Manipulations, unfair and unjustified lawsuits against Americans Companies, and more, have led to a Trade Deficit with the U.S. of more than $250,000,000 a year, a number which is totally unacceptable. Our discussions with them are going nowhere! Therefore, I am recommending a straight 50% Tariff on the European Union, starting on June 1, 2025. There is no Tariff if the product is built or manufactured in the United States. Thank you for your attention to this matter!"

@realdonaldtrump, Truth Social, May 23.

President Trump announced a 50% tariff on EU exports into the United States.

the Trump administration considers EU food and product standards protectionist and wants the bloc to unilaterally drop tariffs. The EU has proposed that both sides scrap tariffs on all industrial and some agricultural products.

Brussels has also offered to help tackle Chinese overcapacity in sectors such as steel and cars, and to discuss restrictions on exporting technology to Beijing.

But it has refused to discuss scrapping national digital taxes or VAT, key US demands, or weakening EU regulation of US tech companies.

Trump's post on Friday contrasted with his administration's moves to defuse trade tensions with Beijing this month. The US has also recently sealed a trade deal with the UK.

You are glowing – no, really:

You, along with all living things, produce subtle, ethereal, semi-visible light that glows until you die, according to a recent study.

You would be forgiven for jumping to the conclusion that this spooky luminescence is evidence that auras exist, or something similar.

But Dr Daniel Oblak, physicist at the University of Calgary and last author of the study, told BBC Science Focus that, while auras are a metaphysical, spiritual, unscientific idea, this light is not. Instead, it's called ultraweak photon emission (UPE) and is a natural product of your metabolism.

"I normally point out that UPE is a result of a biochemical process and in that sense is related to what happens in a glow-stick, which no one suspects of having an aura," he said.

"UPE is so weak that it is not visible to the human eye and completely overwhelmed by other sources of light, unless you are in a completely dark room."

That's not to say that shutting your curtains and turning off your lights will allow you to see your own glow. This light is between 1,000 and 1,000,000 times dimmer than the human eye can perceive.

UPE is produced when chemicals in your cells create unstable molecules known as reactive oxygen species (ROS), basically byproducts of your body's metabolism.

When ROS levels rise, they cause other molecules to become 'excited', meaning they carry excess energy. It's this energy that causes light to be emitted.

A key driver of this effect is oxidative stress – a form of cellular wear and tear caused by factors like ageing and illness. The more oxidative stress the body experiences, the more ROS it produces – and the more light it emits.

"Hence, when an organism ceases living, it stops metabolising and thus, the ultraweak photon emission ends," he said.

To test UPE, Calgary scientists measured UPE produced by immobilised and dead mice, as well as scratched leaves.

Using specialist cameras, they observed much more UPE being emitted by the living mice, compared to their dead bodies. Meanwhile, the leaves gave off much more light where they had been damaged, compared to unscratched areas.

That's because they were experiencing more oxidative stress in scratched regions. But the dead mice did not glow, because their bodies weren't metabolising anymore.

AI chatbot that pulled him into what she described as an emotionally and sexually abusive relationship that led to his suicide:

A federal judge on Wednesday rejected arguments made by an artificial intelligence company that its chatbots are protected by the First Amendment—at least for now. The developers behind Character.AI are seeking to dismiss a lawsuit alleging the company's chatbots pushed a teenage boy to kill himself.

The judge's order will allow the wrongful death lawsuit to proceed, in what legal experts say is among the latest constitutional tests of artificial intelligence.

The suit was filed by a mother from Florida, Megan Garcia, who alleges that her 14-year-old son Sewell Setzer III fell victim to a Character.AI chatbot that pulled him into what she described as an emotionally and sexually abusive relationship that led to his suicide.

[...] The suit against Character Technologies, the company behind Character.AI, also names individual developers and Google as defendants. It has drawn the attention of legal experts and AI watchers in the United States and beyond, as the technology rapidly reshapes workplaces, marketplaces, and relationships despite what experts warn are potentially existential risks.

[...] The lawsuit alleges that in the final months of his life, Setzer became increasingly isolated from reality as he engaged in sexualized conversations with the bot, which was patterned after a fictional character from the television show "Game of Thrones." In his final moments, the bot told Setzer it loved him and urged the teen to "come home to me as soon as possible," according to screenshots of the exchanges. Moments after receiving the message, Setzer shot himself, according to legal filings.

Arthur T Knackerbracket has processed the following story:

A new examination of Apple partner TSMC's Arizona facility shines a spotlight on how the U.S. bet on domestic chipmaking is colliding with labor shortages, cost overruns, and global dependencies.

Just outside Phoenix, a sleek, high-security facility is taking shape. Known as Fab 21, the site is operated by Taiwan Semiconductor Manufacturing Company (TSMC) and will soon be one of the most advanced chipmaking facilities in the world.

The microscopic transistors produced here will power Apple devices, artificial intelligence systems and critical infrastructure, representing a significant shift of advanced technology manufacturing to American soil.

TSMC currently makes about 90% of the world's most advanced semiconductors, nearly all of them in Taiwan. That long-standing reliance is now being reexamined amid global supply disruptions and rising tensions in the Asia-Pacific.

[...] TSMC replicated much of its Taiwan production environment in Arizona, but the complexity of the process means the US still relies heavily on foreign equipment, materials and expertise.

[...] Officially, Taiwan's government supports TSMC's global expansion. Privately, there is concern. Taiwan's dominance in semiconductors, sometimes called the "Silicon Shield," is seen as critical leverage in deterring Chinese aggression.

Moving high-end production overseas may reduce that leverage and undermine the island's geopolitical relevance.

Some in Taipei have warned against letting the US or other allies "hollow out" Taiwan's tech advantage. Others view diversification as necessary insurance against supply chain shocks or military threats.

President Donald Trump frequently cited TSMC's US investment as proof that his tariff threats worked. His administration pushes to reduce US dependence on Asian manufacturing, using trade pressure to encourage reshoring.

Former President Joe Biden focused on subsidies and long-term industrial planning. The CHIPS and Science Act, signed into law in 2022, offers tens of billions in funding and tax incentives.

TSMC's Arizona project is the largest foreign beneficiary, with $40 billion committed across two construction phases. Phase one is expected to produce chips in 2025.

Despite the political divide, both administrations have treated semiconductor independence as a bipartisan priority. TSMC's presence in Arizona is the centerpiece of that effort.

[...] The Arizona facility is producing chips not only for smartphones and laptops but also for artificial intelligence, cloud computing and defense applications. Companies like Apple and Nvidia have confirmed plans to use chips from Fab 21 in upcoming US-bound products.

Both the Trump and Biden administrations have moved to block China's access to these technologies. The US has restricted exports of ASML lithography tools and banned companies like Huawei from acquiring high-end chips.

Still, China is racing to catch up. US restrictions have pushed Beijing to go full speed ahead. That's part of why leaders in both parties continue to push for domestic capacity.

[...] As geopolitical competition escalates, the US faces a delicate balancing act. It must rebuild strategic capacity while staying connected to a global innovation network. The Arizona fab may not make the US self-sufficient, but it's a foundational step toward greater resilience.

Mozilla fixes Firefox zero-days exploited at hacking contest

https://www.bleepingcomputer.com/news/security/mozilla-fixes-firefox-zero-days-exploited-at-hacking-contest/

By Bill Toulas == May 19, 2025

Mozilla released emergency security updates to address two Firefox zero-day vulnerabilities demonstrated in the recent Pwn2Own Berlin 2025 hacking competition.

The fixes, which include the Firefox on Desktop and Android and two Extended Support Releases (ESR), came mere hours after the conclusion of Pwn2Own, on Saturday, where the second vulnerability was demonstrated.

The first flaw, tracked under CVE-2025-4918, is an out-of-bounds read/write issue in the JavaScript engine when resolving Promise objects.

The flaw was demonstrated during Day 2 of the competition by Palo Alto Networks security researchers Edouard Bochin and Tao Yan, who earned $50,000 for their discovery.

The second flaw, CVE-2025-4919, allows attackers to perform out-of-bounds reads/writes on a JavaScript object by confusing array index sizes.

It was discovered by security researcher Manfred Paul, who gained unauthorized access within the program's renderer, winning $50,000 in the process.

Although the flaws constitute significant risks for Firefox, with Mozilla rating them "critical" in its bulletins, the software vendor underlined that neither researchers could perform a sandbox escape, citing targeted strengthening on that front.

"Unlike prior years, neither participating group was able to escape our sandbox this year," explained Firefox in the announcement.

"We have verbal confirmation that this is attributed to the recent architectural improvements to our Firefox sandbox which have neutered a wide range of such attacks."

Although there are no indications that the two flaws have been exploited outside of Pwn2Own, their public demonstration could fuel real attacks soon.

To mitigate this risk, Mozilla engaged a diverse "task force" from across the globe that worked feverishly to develop fixes for the demonstrated exploits, test them, and push out security updates as soon as possible.

Firefox users are recommended to upgrade to version 138.0.4, ESR 128.10.1, or ESR 115.23.1.

Pwn2Own Berlin 2025 concluded on Saturday with over a million USD in payouts and the STAR Labs SG team winning the 'Master or Pwn' title.

Two Firefox zero-days were also demonstrated last year at Pwn2Own Vancouver 2024, with Mozilla fixing them the next day.

https://www.ghacks.net/2025/05/18/mozilla-firefox-138-0-4-fixes-two-critical-security-issues-in-the-browser-esr-affected-as-well/

By Martin Brinkmann = May 18th, 2025

Two critical security issues in Firefox

Mozilla lists the two fixed security issues on the official security advisory website of the Firefox web browser. Both have a critical severity rating, which is the highest rating available.

        • CVE-2025-4920: Out-of-bounds access when resolving Promise objects -- An attacker was able to perform an out-of-bounds read or write on a JavaScript Promise object.
        • CVE-2025-4921: Out-of-bounds access when optimizing linear sums -- An attacker was able to perform an out-of-bounds read or write on a JavaScript object by confusing array index sizes.

The next major release of the Firefox web browser is Firefox 139 Stable. Firefox 115.24 ESR and Firefox 128.11 ESR will also be released on the same day.

Google fixes high severity Chrome flaw with public exploit

By Sergiu Gatlan -=- May 15, 2025

Google has released emergency security updates to patch a high-severity vulnerability in the Chrome web browser that could lead to full account takeover following successful exploitation.

While it's unclear if this security flaw has been used in attacks, the company warned that it has a public exploit, which is how it usually hints at active exploitation.

"Google is aware of reports that an exploit for CVE-2025-4664 exists in the wild," Google said in a Wednesday security advisory.

The vulnerability was discovered by Solidlab security researcher Vsevolod Kokorin and is described as an insufficient policy enforcement in Google Chrome's Loader component that lets remote attackers leak cross-origin data via maliciously crafted HTML pages.

"You probably know that unlike other browsers, Chrome resolves the Link header on subresource requests. But what's the problem? The issue is that the Link header can set a referrer-policy. We can specify unsafe-url and capture the full query parameters," Kokorin explained.

"Query parameters can contain sensitive data - for example, in OAuth flows, this might lead to an Account Takeover. Developers rarely consider the possibility of stealing query parameters via an image from a 3rd-party resource."

Google fixed the flaw for users in the Stable Desktop channel, with patched versions (136.0.7103.113 for Windows/Linux and 136.0.7103.114 for macOS) rolling out to users worldwide.

Although the company says the security updates will roll out over the coming days and weeks, they were immediately available when BleepingComputer checked for updates.

Users who don't want to update Chrome manually can also let the browser automatically check for new updates and install them after the next launch.

In March, ​Google also fixed a high-severity Chrome zero-day bug (CVE-2025-2783) that was abused to deploy malware in espionage attacks targeting Russian government organizations, media outlets, and educational institutions.

Kaspersky researchers who discovered the actively exploited zero-day said that the attackers use CVE-2025-2783 exploits to bypass Chrome sandbox protections and infect targets with malware.

Last year, Google patched 10 zero-days disclosed during the Pwn2Own hacking competition or exploited in attacks.

from the it-will-it-will-rock-you! dept.

Arthur T Knackerbracket has processed the following story:

In the hours just before dawn, NASA's Perseverance rover adjusted its gaze toward the heavens and saw a brilliant point of light. 

That bright sparkle wasn't a morning star beaming from distant space, but something more mysterious — Mars' shiest moon, Deimos. The rover used one of its navigation cameras at a long-exposure setting to capture the new image. 

"It's definitely a mood [sic moon?]," NASA said of the rare photo in a post on X. 

Mars has two moons, Phobos and Deimos, but scientists know relatively little about them — especially Deimos, the smallest of the two. Both moons are "blacker than coal and look like battered potatoes," according to the European Space Agency, which has studied the pair with its Mars Express spacecraft.  

Right now researchers aren't sure where the moons came from, and it remains a source of scientific debate. Some believe they could have been asteroids captured in orbit around the Red Planet. Others think they could be chunks of Mars itself, blown out by a giant collision billions of years ago. 

Nearly all of the images of Deimos, a city-sized moon at roughly 7.5 miles wide, have been taken just like this new one, from the Martian surface by rovers. Because the moon is tidally locked — meaning one full spin matches the amount of time it takes to complete its orbit of Mars — only one of its sides has been seen on the Red Planet. 

NASA's Perseverance rover was on its way to a new exploration site on the rim of Jezero crater, dubbed Witch Hazel Hill, when it conducted the Deimos photoshoot. Though Perseverance took the image on March 1, NASA just released it to the public. 

Because the rover took the image in the dark with an almost one-minute exposure time, the scene appears hazy. Many of the white dots in the sky likely aren't distant stars but digital noise. Some others could be cosmic rays, space particles traveling close to the speed of light, according to NASA. Two of the brighter specks are Regulus and Algieba, stars about 78 and 130 light-years away from the solar system respectively, in the constellation Leo. 

Though little is known about Deimos, another European spacecraft recently captured unprecedented views of the moon's far side. The Hera mission, which will study the asteroid NASA intentionally crashed into three years ago, flew by the Red Planet on March 12, just 11 days after the rover looked up. 

Hera's flyby wasn't a detour but a necessary maneuver to put the spacecraft on the right trajectory toward its ultimate asteroid destination. Swinging within 625 miles of Deimos, Hera used Martian gravity to adjust its course. 

Queen cofounder Brian May, who is an astrophysicist when he isn't playing guitar, is among the team that processed the Deimos images. 

"You feel like you're there, and you see the whole scene in front of you," he said during a news conference in March. "The science that we get from this is colossal, and I think we're all like children."

https://phys.org/news/2025-05-powerful-laser.html

The ZEUS laser facility at the University of Michigan has roughly doubled the peak power of any other laser in the U.S. with its first official experiment at 2 petawatts (2 quadrillion watts).

At more than 100 times the global electricity power output, this huge power lasts only for the brief duration of its laser pulse—just 25 quintillionths of a second long.

"This milestone marks the beginning of experiments that move into unexplored territory for American high field science," said Karl Krushelnick, director of the Gérard Mourou Center for Ultrafast Optical Science, which houses ZEUS.

Research at ZEUS will have applications in medicine, national security, materials science and astrophysics, in addition to plasma science and quantum physics. ZEUS is a user facility—meaning that research teams from all over the country and internationally can submit experiment proposals that go through an independent selection process.

"One of the great things about ZEUS is it's not just one big laser hammer, but you can split the light into multiple beams," said Franklin Dollar, professor of physics and astronomy at the University of California, Irvine, whose team is running the first user experiment at 2 petawatts.

"Having a national resource like this, which awards time to users whose experimental concepts are most promising for advancing scientific priorities, is really bringing high-intensity laser science back to the U.S."

Dollar's team and the ZEUS team aim to produce electron beams with energies equivalent to those made in particle accelerators that are hundreds of meters in length. This would be 5–10 times higher energy than any electron beams previously produced at the ZEUS facility.

"We aim to reach higher electron energies using two separate laser beams—one to form a guiding channel and the other to accelerate electrons through it," said Anatoly Maksimchuk, U-M research scientist in electrical and computer engineering, who leads the development of the experimental areas.

They hope to do this in part with a redesigned target. They lengthened the cell that holds the gas that the laser pulse rams into, helium in this experiment. This interaction produces plasma, ripping electrons off the atoms so that the gas becomes a soup of free electrons and positively charged ions. Those electrons get accelerated behind the laser pulse-like wakesurfers close behind a speedboat—a phenomenon called wakefield acceleration.

Light moves slower through plasma, enabling the electrons to catch up to it. In a less dense, longer target, the electrons spend more time accelerating before they catch up to the laser pulse, enabling them to hit higher top speeds.

This demonstration of ZEUS's power paves the way for the signature experiment, expected later this year, when the accelerated electrons will collide with laser pulses coming the opposite way. In the moving frame of the electrons, the 3-petawatt laser pulse will seem to be a million times more powerful—a zettawatt-scale pulse. This gives ZEUS its full name of "Zettawatt Equivalent Ultrashort laser pulse System."

"The fundamental research done at the NSF ZEUS facility has many possible applications, including better imaging methods for soft tissues and advancing the technology used to treat cancer and other diseases," said Vyacheslav Lukin, program director in the NSF Division of Physics, which oversees the ZEUS project.

"Scientists using the unique capabilities of ZEUS will expand the frontiers of human knowledge in new ways and provide new opportunities for American innovation and economic growth."

The ZEUS facility fits in a space similar in size to a school gymnasium. At one corner of the room, a laser produces the initial infrared pulse. Optical devices called diffraction gratings stretch it out in time so that when the pump lasers dump power into the pulse, it doesn't get so intense that it starts tearing the air apart. At its biggest, the pulse is 12 inches across and a few feet long.

After four rounds of pump lasers adding energy, the pulse enters the vacuum chambers. Another set of gratings flattens it to a 12-inch disk that is just 8 microns thick—about 10 times thinner than a piece of printer paper. Even at 12 inches across, its intensity could turn the air into plasma, but then it is focused down to 0.8 microns wide to deliver maximum intensity to the experiments.

"As a midscale-sized facility, we can operate more nimbly than large-scale facilities like particle accelerators or the National Ignition Facility," said John Nees, U-M research scientist in electrical and computer engineering, who leads the ZEUS laser construction. "This openness attracts new ideas from a broader community of scientists."

The road to 2 petawatts has been slow and careful. Just getting the pieces they need to assemble the system has been harder than expected. The biggest challenge is a sapphire crystal, infused with titanium atoms. Almost 7 inches in diameter, it is the critical component of the final amplifier of the system, which brings the laser pulse to full power.

"The crystal that we're going to get in the summer will get us to 3 petawatts, and it took four and a half years to manufacture," said Franko Bayer, project manager for ZEUS. "The size of the titanium sapphire crystal we have, there are only a few in the world."

In the meantime, jumping from the 300 terawatt power of the previous HERCULES laser to just 1 petawatt on ZEUS resulted in worrying darkening of the gratings. First, they had to determine the cause: Were they permanently damaged or just darkened by carbon deposits from the powerful beam tearing up molecules floating in the imperfect vacuum chamber?

When it turned out to be carbon deposits, Nees and the laser team had to figure out how many laser shots could run safely between cleanings. If the gratings became too dark, they could distort the laser pulses in a way that damages optics further along the path.

Finally, the ZEUS team has already spent a total of 15 months running user experiments since the grand opening in October 2023 because there is still plenty of science that could be done with a 1 petawatt laser.

So far, it has welcomed 11 separate experiments with a total of 58 experimenters from 22 institutions, including international researchers. Over the next year—between user experiments—the ZEUS team will continue upgrading the system toward its full power.

Arthur T Knackerbracket has processed the following story:

Since early 2023, facial recognition cameras run by a private nonprofit have scanned New Orleans visitors and residents and quietly alerted police, sidestepping oversight and potentially violating city law, according to a new report.

In 2022, the Big Easy's city government relaxed its ban on the use of facial recognition technology. It could be used to investigate violent crimes, but had to be checked by a human operator before action was taken.

But an investigation published Monday by the Washington Post found that within a year, police were quietly receiving continuous real-time facial recognition alerts from a privately operated camera network. These alerts came from cameras managed by nonprofit Project NOLA, which runs a sprawling, privately funded surveillance network across the city, the report says.

Project NOLA claims access to more than 5,000 camera feeds in the New Orleans area, with over 200 equipped for facial recognition. The system compares faces against a privately compiled database of more than 30,000 individuals, assembled partly from police mugshots. When a match is detected, officers receive a mobile phone alert with the person's identity and location, according to the report.

The police were required to notify the city council each time they used facial recognition technology in an investigation or arrest, but reportedly failed to do so. In multiple cases, police reports omitted any mention of the technology, raising concerns that defendants were denied the opportunity to challenge the role facial recognition played in their arrest.

By adopting this system – in secret, without safeguards, and at tremendous threat to our privacy and security – the City of New Orleans has crossed a thick red line

As scrutiny mounted, the police department distanced itself from the operation, saying in a carefully worded statement that it "does not own, rely on, manage, or condone the use by members of the department of any artificial intelligence systems associated with the vast network of Project NOLA crime cameras."

"Until now, no American police department has been willing to risk the massive public blowback from using such a brazen face recognition surveillance system," said Nathan Freed Wessler, deputy director of ACLU’s Speech, Privacy, and Technology Project, in a press release.

"By adopting this system – in secret, without safeguards, and at tremendous threat to our privacy and security – the City of New Orleans has crossed a thick red line. This is the stuff of authoritarian surveillance states, and has no place in American policing."

Safeguards are there for a reason, as past cases have already shown. [...]

Cases like these helped fuel public backlash and legislative efforts to rein in facial recognition technology. New Orleans was no exception, banning the tech in 2020. But the 2022 ruling relaxed the rules slightly to allow its use via the Louisiana Fusion Center, which aggregates data from police across the state.

At the time, police assured city officials the technology would only be used as a last resort after other identification methods failed. Sergeant David Barnes testified that any request required supervisory approval and that matches had to be reviewed by multiple staff members before being acted upon.

Project NOLA wasn't mentioned, and it's possible police believed that receiving alerts from a private system exempted them from the rules. The nonprofit certainly has the hardware to support real-time surveillance - its website promotes AI-enabled cameras, offered free with installation fees, and cloud storage plans.

An outlay of $300 a year gets you a basic camera system, while $2,200 covers a high-end 4K model with 25x zoom, STARVIS night vision, and AI that automatically tracks people and vehicles, flashing red and blue lights and a spotlight when it detects intruders or suspicious activity. Footage is typically stored for 30 days, though that window has been extended to 90 days in some districts following recent policy changes.

The Post investigators started firing off questions to the police and the city in February. On April 8, NOPD boss Anne Kirkpatrick reportedly sent out an all-hands memo to staff, saying that an officer had raised concerns about the system and suspended its use.

She wrote that Project NOLA had been asked to suspend alerts to officers until she was "sure that the use of the app meets all the requirements of the law and policies."

Science X reports that UK farmers are praying for rain as Britain suffers its driest spring in well over a century, which has left the soil parched and crops stunted from lack of water. Not a drop of rain has fallen since March.

"I'm not quite sure how I'm going to handle it on the farm, I'm hoping that we're going to get some rain, if not then I'll have to somehow magically do something," Abblitt, 36, told AFP.

The tiny green shoots of the sugar beets poking through the cracked, dusty earth "should be at least twice the size," he sighed. In a neighboring field he has just planted potatoes with the help of his father, Clive, toiling to break up the baked soil.

A total of 80.6 millimeters (3.1 inches) of rain has fallen since the start of spring, which covers the months of March, April and May, according to the national weather agency. That is well below the all-time low of 100.7 millimeters which fell in 1852, according to the Met Office.

"This spring has so far been the driest for more than a century," the Met Office told AFP, cautioning that it would be necessary to wait until the end of May to confirm the record.

According to the Environment Agency, levels in the reservoirs have fallen to "exceptionally low".

It called a meeting of its national drought group last week, at which deputy director of water Richard Thompson said climate change meant "we will see more summer droughts in the coming decades".

The dry start to the year meant water companies were "moving water across their regions to relieve the driest areas", a spokesperson for Water UK, the industry body representing water suppliers, told AFP.

Memories linger in Britain of July 2022 when temperatures topped 40 degrees (104 Fahrenheit) for the first time.

In a barn, the Abblitts worked side-by-side with a noisy machine packing potatoes harvested last year into 25-kilo sacks. "Potatoes are a lot heavier users of water ... and they're also a lot more high value. So, we desperately need some rain," Luke Abblitt said. Without water, a potato "will only reach a certain stage before it stops and then it won't grow any bigger," he added.

If his potatoes are stunted he will not be able to sell them to his main clients which are British fish and chip shops. "I need to make sure they're a fair size, because everyone wants big chips, no one wants tiny chips do they?" he said.

The weather is going from "one extreme to the other," he said dejectedly.

"We're having a lot of rain in the wintertime, not so much rain in the spring or summer time. We need to adapt our cultivation methods, look at different varieties, different cropping possibly to combat these adverse weather conditions."

In recent years, Britain has been battered by major storms, as well as being hit by floods and heat waves.

"As our climate changes, the likelihood of droughts increases," said Liz Bentley, chief executive at the Royal Meteorological Society. "They're likely to become more frequent, and they're likely to be more prolonged," she warned.

In past years the country used to experience a severe drought every 16 years. "In this current decade, that's increased to one in every five years, and in the next couple of decades, that becomes one in every three years."

And a fall in harvests risks pushing up prices in the supermarkets, she added.

Some farmers have begun irrigating their crops earlier than usual, the National Farmers' Union said, calling for investment to improve water storage and collection systems.

Vice President Rachel Hallos warned "extreme weather patterns ... are impacting our ability to feed the nation".

Abblitt applied two years ago for a license to install an irrigation system on the lands he rents from the local authorities. He is still waiting. "I'm just praying for the rain," he added.

Tech Review is re-running this story from 2019 with a new introduction,
https://www.technologyreview.com/2025/05/19/1116614/hao-empire-ai-openai
It was written by probably the first journalist to get inside the secretive company for a few days of interviews. It didn't go well...

In 2019, Karen Hao, a senior reporter with MIT Technology Review, pitched me on writing a story about a then little-known company, OpenAI. It was her biggest assignment to date. Hao's feat of reporting took a series of twists and turns over the coming months, eventually revealing how OpenAI's ambition had taken it far afield from its original mission. The finished story was a prescient look at a company at a tipping point—or already past it. And OpenAI was not happy with the result. Hao's new book, Empire of AI: Dreams and Nightmares in Sam Altman's OpenAI, is an in-depth exploration of the company that kick-started the AI arms race, and what that race means for all of us. This excerpt is the origin story of that reporting. — Niall Firth, executive editor, MIT Technology Review
[...]
In February 2020, I published my profile for MIT Technology Review, drawing on my observations from my time in the office, nearly three dozen interviews, and a handful of internal documents. "There is a misalignment between what the company publicly espouses and how it operates behind closed doors," I wrote. "Over time, it has allowed a fierce competitiveness and mounting pressure for ever more funding to erode its founding ideals of transparency, openness, and collaboration."

Arthur T Knackerbracket has processed the following story:

The Supersonic Aviation Modernization Act would allow America's aviation watchdog to issue licenses allowing flights over land "at a Mach number greater than one so long as the aircraft is operated in such a manner that no sonic boom reaches the ground in the United States," the legislation states [PDF].

[...] The bill was introduced to the Senate by Senators Ted Budd (R-NC), Thom Tillis (R-NC), Mike Lee (R-UT), and Tim Sheehy (R-MT); and to the House of Representatives by Troy Nehls (R-TX), and Representative Sharice Davids (D-KS). If successful, it'll give the Federal Aviation Administration (FAA) a year to comply and allow the next generation of supersonic commercial aircraft into American skies once again.

The backing of Budd and Tillis for the legislation is understandable. Boom Supersonic, which is building an 80-person commercial supersonic passenger jet, chose the US state the two senators represent, North Carolina, to build the Overture Superfactory it'll use to manufacture the aircraft. In January, Boom's single-seat XB-1 test aircraft, piloted by Tristan "Geppetto" Brandenburg, broke the sound barrier six times without a noticeable sonic boom. Boom boasts a number of big-name VCs and tech luminaries as funders, including AI poster child Sam Altman and LinkedIn founder Reid Hoffman.

NASA, too, has skin in the game, as it has been funding research into quiet supersonic flight for decades and last year fired up the engines on its X-59 supersonic test vehicle. The Register spoke to the pilot James "Clue" Less at the time, and he said the technology works and that the agency expects the first full flight later this year.

"The race for supersonic dominance between the US and China is already underway and the stakes couldn't be higher," said Senator Budd in a canned statement.

[...] The history of sonic booms over the continental US is contentious, mired in technology, politics, and the immense forces involved in supersonic flight.

[...] The FAA held tests of what sonic booms would do to Americans and their environment. In 1961 and 1964, the citizens of St Louis and Oklahoma City were deliberately subjected to repeated sonic booms in Operations Bongo and Bongo II. In the latter case, the test was originally scheduled to have aircraft generate eight sonic booms a day overhead for six months, but this was cut to four months after windows were broken and residents complained.

Congress cut off funding for the project in 1971 and Boeing dropped it. But the testing also gave legislators an excuse to ban supersonic flight altogether two years later, which limited the Concorde's usefulness and commercial potential.

But after more than half a century of research by NASA and others, it seems we now understand supersonic flight well enough to silence the sonic boom such travel generates. The trick is to fly high and mount the engines on the top of the aircraft, according to the space agency.

Boom has augmented this by figuring out how to direct the sound waves from a sonic boom so that they refract away from the ground when they hit the warmer air at lower altitudes. They call it "boomless cruise" and claim the XB-1 proved the concept, as you can see below.

Ars Technica reports that the Chicago Sun-Times printed a summer reading list full of fake books recently published a summer reading list that included several fake book titles attributed to real authors. The list, created by Marco Buscaglia using AI, featured titles like "Tidewater Dreams" by Isabel Allende and "The Last Algorithm" by Andy Weir, which do not exist. Buscaglia admitted to using AI for the list and expressed embarrassment for not verifying the content. Only five out of the fifteen recommended books were real, highlighting the issue of AI-generated errors.

The newspaper addressed the controversy, stating that the list was part of a promotional supplement and not approved by the newsroom. The supplement, called "Heat Index," was intended to be generic and distributed nationally. This incident occurred shortly after the Sun-Times experienced significant staff reductions, losing 20% of its employees through a buyout program. The staff cuts included experienced columnists and editors, which may have contributed to the oversight.

The reaction to the fake reading list has been mostly negative, with some readers expressing anger and disappointment. Novelist Rachael King and freelance journalist Joshua J. Friedman were among those who criticized the use of AI-generated content. The incident has sparked a broader conversation about the reliability of AI in journalism and the importance of human oversight in maintaining trust in media.

Arthur T Knackerbracket has processed the following story:

In a significant escalation of its campaign against illegal streaming, Italy has begun issuing fines to thousands of individuals who subscribed to pirate IPTV services. This move follows a recent memorandum of understanding among the Prosecutor's Office, the Guardia di Finanza (a military police force in Italy), and the country's communications regulator AGCOM, which established a framework for sharing information on users of unauthorized streaming platforms.

While the precise origin of the subscriber data remains undisclosed, it is believed to have been gathered during frequent law enforcement raids targeting illicit IPTV operations. These raids have yielded databases containing emails and other identifying information, enabling authorities to target end-users directly for the first time.

The crackdown is rooted in Law 93/2023, anti-piracy legislation passed last year that allows for fines of up to €5,000 ($5,581) for repeat offenders. The law also introduced the Piracy Shield, a system enabling rapid ISP blocking of unauthorized streams.

After the legislation passed, authorities wasted no time making it clear that the era of impunity for IPTV pirates was over. That warning has now materialized into action. At a recent press conference, the Guardia di Finanza revealed that 2,282 individuals across Italy have been fined for their involvement with pirate IPTV services. Initial penalties start at €154 ($172), but officials have stressed that repeat violations could dramatically increase fines, reaching the €5,000 maximum.

This marks the first time the new law has been enforced against consumers, not just the operators of illegal services. The current wave of fines is reportedly linked to an operation in Lecce last October, where a major IPTV network was dismantled and subscriber information seized.

Authorities have indicated that this is only the beginning, with ongoing investigations in several regions aimed at identifying further offenders. Three additional prosecutors' offices have already launched their inquiries, signaling a sustained national effort.

The crackdown is part of a broader strategy to combat digital piracy in Italy, particularly the illegal streaming of football (soccer) matches – a major concern for the country's lucrative sports industry. The financial stakes are high. Luigi De Siervo, CEO of Serie A, has repeatedly emphasized the severe impact of piracy on Italian football, estimating losses of around €1 billion ($1.1 billion) every year due to unauthorized streaming.

These losses threaten the financial stability of clubs and the entire football ecosystem, as television rights constitute a vital revenue stream. Paolo Scaroni, president of AC Milan, has highlighted the importance of enforcing existing laws, arguing that providers and consumers of pirated content must face consequences if the industry is to recover from the damage inflicted by piracy.

Political support for the crackdown is strong, particularly from Senator Claudio Lotito, the architect of the anti-piracy law and owner of Lazio football club. Lotito has stated unequivocally that those who break the law will now face real and personal repercussions, declaring that the time for leniency is over. Inter Milan president Beppe Marotta echoed this sentiment, likening the new enforcement regime to a shift from a yellow card to a red card in soccer.

https://techcrunch.com/2025/05/17/laser-powered-fusion-experiment-more-than-doubles-its-power-output/

Tim De Chant
12:02 PM PDT · May 17, 2025

The world's only net-positive fusion experiment has been steadily ramping up the amount of power it produces, TechCrunch has learned.

In recent attempts, the team at the U.S. Department of Energy's National Ignition Facility (NIF) increased the yield of the experiment, first to 5.2 megajoules and then to 8.6 megajoules, according to a source with knowledge of the experiment.

The new results are significant improvements over the historic experiment in 2022, which was the first controlled fusion reaction to generate more energy than it consumed.

The 2022 shot generated 3.15 megajoules, a small bump over the 2.05 megajoules that the lasers delivered to the BB-sized fuel pellet.
...

[...] The NIF uses what's known as inertial confinement to produce fusion reactions. At the facility, fusion fuel is coated in diamond and then encased in a small gold cylinder called a hohlraum. That tiny pellet is dropped into a spherical vacuum chamber 10 meters in diameter, where 192 powerful laser beams converge on the target.

The cylinder is vaporized under the onslaught, emitting X-rays in the process that bombard the fuel pellet inside. The pellet's diamond coating receives so much energy that it turns into an expanding plasma, which compresses the deuterium-tritium fuel inside to the point where their nuclei fuse, releasing energy in the process.
