“Members of the CA/Browser Forum have voted to slash cert lifespans from the current one year to 47 days,” reports Computerworld, “placing an added burden on enterprise IT staff who must ensure they are updated.”

In a move that will likely force IT to much more aggressively use web certificate automation services, the Certification Authority Browser Forum (CA/Browser Forum), a gathering of certificate issuers and suppliers of applications that use certificates, voted [last week] to radically slash the lifespan of the certificates that verify the ownership of sites.

The approved changes, which passed overwhelmingly, will be phased in gradually through March 2029, when the certs will only last 47 days.

This controversial change has been debated extensively for more than a year. The group’s argument is that this will improve web security in various ways, but some have argued that the group’s members have a strong alternative incentive, as they will be the ones earning more money due to this acceleration… Although the group voted overwhelmingly to approve the change, with zero “No” votes, not every member agreed with the decision; five members abstained…

In roughly one year, on March 15, 2026, the “maximum TLS certificate lifespan shrinks to 200 days. This accommodates a six-month renewal cadence. The DCV reuse period reduces to 200 days,” according to the passed ballot. The next year, on March 15, 2027, the “maximum TLS certificate lifespan shrinks to 100 days. This accommodates a three-month renewal cadence. The DCV reuse period reduces to 100 days.” And on March 15, 2029, “maximum TLS certificate lifespan shrinks to 47 days. This accommodates a one-month renewal cadence. The DCV reuse period reduces to 10 days.”

The changes “were primarily pushed by Apple,” according to the article, partly to allow more effective reactions to possible changes in cryptography.

And Apple also wrote that the shift “reduces the risk of improper validation, the scope of improper validation perpetuation, and the opportunities for misissued certificates to negatively impact the ecosystem and its relying parties.”

Spoilers for “Lux.”

It’s an interesting time to be a long-running science fantasy media property in the streaming TV age. Star Trek is in the grip of an existential crisis as it (wrongly) fears it’s too old-aged to be relevant. Star Wars became a battlefield in the culture war and, to duck all future bad faith criticism, gave us The Rise of Skywalker. And then there’s Doctor Who, which is somehow managing to plough a 62-year furrow and still fill it with original ideas. Don’t believe me? This week the Doctor and Belinda go up against a sentient cartoon holding the patrons of a 1950s cinema hostage.

James Pardon / BBC Studios / Disney / Bad Wolf

It’s 1952 in a sparsely populated cinema as the audience watches a breathless newsreel on the power of the atomic bomb. The projectionist flips over to a Merrie Melodies-style cartoon of Mr. Ring-A-Ding (voiced by Alan Cumming), an old-timey song-and-dance character. Just then, a beam of moonlight shines through the window, reflecting off a teaspoon and strikes the screen. Mr. Ring-A-Ding comes to life, talking directly to the scoffing audience before emerging into the theater to the sound of screams.

Meanwhile, the Doctor and Belinda are in the TARDIS trying to work out why it’s refusing to land on May 24, 2025. Belinda asks why he doesn’t just take the ship back to his home planet for a fix, but she doesn’t get a satisfactory answer. Instead, the Doctor has built a gadget that will help pull the TARDIS back to the present day, it just needs to land in a few other places first. The pair wind up in Miami in 1952 and while the Doctor initially insists Belinda stay indoors, she’s eager to see what it’s like.

They step out into the night (slash early morning) of 1952 Miami, outside the cinema from the pre-credits, albeit three months after Mr. Ring-A-Ding came to life. Since then, the theater has been locked shut, with the 15 patrons in the audience going missing; the projectionist, Reginald Pye, has stayed behind to act as caretaker, playing films to an empty room.

They visit the diner across the street and meet the mother of one of the missing patrons, Mrs. Lowenstein, who fills in the backstory. They head into the cinema and Mr. Ring-A-Ding makes it clear he’s about to trap them in film before a Mr. Ring-A-Ding short stays playing on the screen. While he’s distracted, the Doctor and Belinda hot-foot it to the projection room where they meet Pye, who has been looking after the cinema patrons, all of whom have been trapped in a strip of film.

Pye has been keeping Mr. Ring-a-Ding alive and appeased by playing movies for him every night. But the sinister cartoon has also given Pye something in return: He has a film of his late wife who Mr. Ring-A-Ding can bring back as a “real” person, at least for a few moments each night. Following on the theme of coercion from last week, the carrot is also a stick, since Mr. Ring-A-Ding also threatens to destroy that film if Pye steps out of line.

Naturally, Mr. Ring-A-Ding isn’t just a beloved old-timey cartoon character but a god, one of the same pantheon as the Toymaker, Maestro and Sutekh. His real identity is Lux Imperator, or Lord of Light, and he’s determined to consume all the light he can, including the most delicious (potential) meal of all — the atom bomb he’s been learning about in the newsreels. To prevent the Doctor and Belinda frustrating his plans, he manages to trap them in a cartoon.

The Doctor and Belinda are turned into two-dimensional drawings, with two-dimensional minds and characterizations. In their panic, they confess their anxieties, including the Doctor’s worries he can’t get Belinda home. As they do so, they acquire physical depth until they return to their normal selves, and then break (okay, knocking over) the fourth wall into… someone’s living room.

The Doctor and Belinda are greeted by a trio of Doctor Who fans watching the episode who are shocked and delighted to meet their heroes. The fans, Hassan Chowdry (Samir Arrian), Lizzie Abel (Bronté Barbé) and Robyn Gossage (Steph Lacey) explain, uh, Doctor Who to the Doctor. The season’s subconscious theme of Steven Moffat envy continues, with the trio saying their favorite episode is “Blink.” Robyn also points out that the end of the episode is pretty obvious given that celluloid is highly explosive. There’s even time for the fans to be called annoying — a facet they (like all “good” Doctor Who fans) will admit to with a heavy dose of self-awareness.

The trio ready to kick the Doctor out as the episode hits the 30-minute mark, which means it’s time for the third act. But they’re also sad, realizing that they’re the fictitious ones, not the Doctor and Belinda, as they don’t have surnames. They know the characters that don’t have surnames are unimportant, incidental figures in the story that will die when the time travelers crawl back through the screen. (Aside: They do in the closing credits, something that Davies’ alluded to in his most recent column for Doctor Who Magazine talking about the realities of giving one-shot characters names for the credits.)

The Doctor and Belinda return to the cinema, where the previously kind Mrs. Lowenstein has hauled a police officer in to arrest the pair for trespassing in a whites-only cinema. The Doctor fairly instantly calls BS, especially since the police officer is wearing a New York-style uniform: They’re still in the film, and when they break out, the Doctor and Belinda meet Lux / Mr. Ring-A-Ding once again. Lux magically summons up long lengths of filmstrips that act like ropes, wrapping them around his wrists and raising him up high. He turns on the projector which draws the Doctor’s regeneration out as light, projected onto Mr. Ring. A Ding.

Belinda, meanwhile, heads off to a storage cupboard, pulls out lots of film and throws it on the floor. But Reginald the projectionist won’t give her the matches she needs to start the fire until, uh, the ghost of his wife, briefly returning as a solid person, hands him the matches. Belinda then blows a hole in the roof of the cinema big enough to expose Mr. Ring-A-Ding to sunlight, which causes him to exponentially grow until he’s not just bigger than the planet but bigger than the universe itself. Or something.

In the daylight of Miami, Belinda asks the Doctor how exactly Lux / Mr. Ring-A-Ding was destroyed. “We’re 60 percent water and we can still drown,” he explains as the formerly trapped patrons of the cinema emerge from their three month imprisonment. The Doctor and Belinda have bonded over their shared worries, and Belinda is a lot more comfortable with her slightly longer route home. As they head into the TARDIS, Mrs. Flood greets the crowd and tells them if they want to see a really exciting sight, they should watch the ship disappear. Sadly, she adds, it’s a “limited run,” which will end on May 24th.

Eight disconnected thoughts about “Lux.”

Density

Like “The Robot Revolution” before it, “Lux” is packed full of concepts and themes that could easily be the sole subject of a story. This thematic density has always been a part of Doctor Who — a show that has often worn its deep political and literary ambitions on its sleeve — but it can be both a blessing and a curse.

Just think about the sheer number of ideas this one episode is playing with, touching upon:

• How time travel as a plot device can be implicated by race.

• How media habits and consumption have changed in the last century.

• How human nature hasn’t changed in the last century.

• How awful it is to be held hostage by your own desire.

• What it would be like if a fictional character discovered they were fictional.

That’s a hell of a lot of stuff to get through in 45 minutes, even if you’re not going to explore any of them. Though it may be a thrilling high-wire act Davies is pulling off, the result doesn’t have anything weighty to say. Not that I expect or need every episode to be About Something In A Very Special Way, but these themes aren’t meant to be just window dressing.

Ironically, and to contradict what I just wrote, I found “Lux” to be far more enjoyable than “The Robot Revolution.” Free of the burden of having to introduce Belinda and lay down the shape of this year’s overarching storyline, the episode is able to focus on just being itself. Everything here joins up in a more satisfying way, and the emotional beats, while rushed, at least make sense.

Rhyming history

As soon as Ncuti Gatwa was held aloft by moving filmstrips, I realized how closely the scene mirrored the conclusion of “The Devil’s Chord.” I’m not surprised, given both episodes feature the Doctor fighting a member of the Pantheon’s roster of rogue gods. After all, our heroes turn up in what is ostensibly the past of our living memory (‘60s last year, ‘50s here) to battle a god using pop culture as a vehicle (music then, cinema now). For the filmstrips here, Maestro dragged the Doctor and Ruby around Abbey Road with ribbons of music notation.

Soft Elbows

In the few times Doctor Who has acknowledged its fanbase, it’s with a loving elbow to their ribcages. It helps that the series is so tied to the UK’s cultural DNA that everyone is a fan, even if they’re not a fan. Perhaps more importantly, Davies, Moffat and Chibnall were all prominent fans before they had TV careers. All of us are capable of conceding we are (or can be) bloody annoying at times and insufferably smug at others.

One thing did occur to me: All three times Doctor Who has acknowledged its fanbase — Whizzkid in “Greatest Show”, the members of LINDA in “Love and Monsters” and here — the themes are the same. Doctor Who fans are always kind-hearted, a little bit annoying and they get taken advantage of by a bad faith figure (Captain Cook, Victor Kennedy and Lux). Isn’t that interesting?

Importance

A key trait of Ncuti Gatwa’s Doctor is his compassion, even going so far as to kiss a Roomba to apologize for turning it off. When Hassan, Lizzie and Robyn say they’re “not important” as surname-less side characters, it irked me that the Doctor didn’t push back. 

Production

Much like last week’s episode, “Lux” is wonderfully well-made with every quarter of the production team operating at their peak. Mr Ring–A-Ding is a triumph, capturing the rubber hose style of animation from that era utterly perfectly. The 2D version is great, and the 3D edition he tries to evolve into at the conclusion is the right sort of horrifying.

Belinda

After “The Robot Revolution,” plenty of fans online suggested Belinda knew a little more than she was meant to. Specifically, she knew the name of the TARDIS despite the Doctor calling it his spaceship earlier in the episode. At the start of “Lux,” Belinda says the Doctor is a Time Lord so his people should be able to fix the malfunctioning TARDIS.

I can see why fans, trained on mystery box shows, would be intent on mining lines of dialog in this fashion. But I think they’re chasing shadows: Davies has never been that sort of writer and probably isn’t going to start seeding his dialog with hints that subtle now. The way I read it, the Doctor has probably gotten used to giving new friends an (off-screen) introduction of the basics.

You could easily imagine a cut-for-necessity scene where the Doctor rattles off the whole “time lord with their own time and space machine” spiel. And you’d expect them not to race toward the more trauma-dump-y elements of their biography, like being the last of them still alive. Belinda was also surprised to see the TARDIS land in 1950s Miami, even after seeing it in space last week. Given the theme of the episode was Belinda slowly embracing her time with the Doctor it makes more sense.

That said, it’s interesting that Davies’ specifically focused on the surnames of minor characters for his column in this month’s Doctor Who Magazine. Naturally, he was wrapping a tease for a future episode inside an anecdote about having to clear even minor character surnames with the show’s legal department. And when the Doctor meets the fans, Robyn points out she knows how the episode ends because she read the leak about it online. I should admit, too, that I read the fairly detailed leak about this episode that included the reveal of this fourth-wall-destroying scene. I would never suggest Davies is playing four-dimensional chess with the audience, but if the detailed leak of this episode came from the production office as a further tweak of the metafiction then, bravo.

Queer representation

The awning outside the cinema is advertising a Rock Hudson movie, and Belinda comments that she learned about the late actor on a HIV training course. He was one of the first people in the public eye to pass away from AIDS, causing a shift in public attitudes. Before Hudson’s death, the US had refused to sanction additional funds to support research into combatting the disease. 

Doctor Who has shied away from directly addressing plenty of social issues during its long run, or even allegorically. Despite the vast number of queer people who were involved in its creation and production, such topics were treated as taboo. That the show can now make such a direct reference to Hudson feels refreshing, especially if it prompts some folks to read up on the issue.

The politics of race

There are better qualified writers who can discuss the issues around race and racism that the episode features. “Lux” is set in 1952, two years before Brown v. Board of Education, in a Miami that is segregated. It’s not the first episode of Doctor Who to deal with this, nor the first of Ncuti Gatwa’s tenure that has intentionally highlighted that the Doctor is played by an actor of color.

I suspect that one moment in particular will provoke discussion: When Belinda is outraged to learn the diner is segregated. The Doctor shuts down her objections, saying that he has toppled worlds, and has sometimes lived in worlds and let them “topple themselves.” For the latter, his approach is to “shut up and shine,” suggesting he sits on the respectability politics-end of the spectrum.

It’s perhaps here that we see the limits of what stories Doctor Who can tell given these events took place in our own recent history. The lead character can topple other worlds in any era, but given we’re all aware of human history, can’t act to rid the world of this injustice. Which affirms the theory that the show is fundamentally conservative in nature since one of the Doctor’s main driving forces is to protect the course of history as it presently is.

Mrs. Flood corner

Now we know Mrs. Flood can appear wherever the TARDIS is, so it’s likely she’ll be popping up in every episode, just like Susan Twist did last year. Here, she simply repeated her ominous threat that the Doctor’s time is running out, which is due to happen on May 24th. May 24th is when this season’s seventh and penultimate episode will air.

An anonymous reader shared this report from CNBC:

Neurotech startup Precision Neuroscience on Thursday announced that a core component of its brain implant system has been approved by the U.S. Food and Drug Administration, a major win for the four-year-old company… The company’s brain-computer interface will initially be used to help patients with severe paralysis restore functions such as speech and movement, according to its website.

Only part of Precision’s system was approved by the FDA on Thursday, but it marks the first full regulatory clearance granted to a company developing a wireless BCI, Precision said in a release. Other prominent startups in the space include Elon Musk’s Neuralink, and Synchron, which is backed by Amazon founder Jeff Bezos and Microsoft co-founder Bill Gates….

The piece of Precision’s system that the FDA approved is called the Layer 7 Cortical Interface. The microelectrode array is thinner than a human hair and resembles a piece of yellow scotch tape. Each array is made up of 1,024 electrodes that can record, monitor and stimulate electrical activity on the brain’s surface. When it is placed on the brain, Precision says it can conform to the surface without damaging any tissue. The FDA authorized Layer 7 to be implanted in patients for up to 30 days, and Precision will be able to market the technology for use in clinical settings. This means surgeons will be able to use the array during procedures to map brain signals, for instance. It is not Precision’s end goal for the technology, but it will help the company generate revenue in the near term.

Precision’s co-founder and chief science officer also helped co-found Musk’s Neuralink in 2017 before departing the following year, according to the article. He nows says this regulatory clearance “will exponentially increase our access to diverse, high-quality data, which will help us to build BCI systems that work more effectively.”

A NASA spacecraft will make a close approach to an asteroid in the main belt on Sunday afternoon, in the second of several asteroid flybys planned for its 12-year mission to study remnants of the early solar system. The Lucy spacecraft will be 596 miles (960 km) from asteroid Donaldjohanson — named after the paleoanthropologist who discovered the “Lucy” hominin fossil — at the closest point of its pass, which will occur at 1:51PM ET, according to NASA. Lucy will use three instruments to capture detailed observations as the object gets closer, rotating with the asteroid over a few hours to get the full picture. It will stop tracking just before the asteroid is nearest, when it’ll have to shield its instruments due to the position of the sun to prevent damaging them.

The spacecraft previously visited a small asteroid called Dinkinesh in 2023, and its observations revealed that the asteroid is orbited by what’s known as a contact binary, or a peanut-shaped double moon “made of two smaller objects touching each other,” NASA explained at the time. After Donaldjohanson, Lucy will move on to its main targets, a handful of “Trojan” asteroids orbiting the sun in the same path as Jupiter. It’s expected to reach the first of those objects in 2027.

“Every asteroid has a different story to tell, and these stories weave together to paint the history of our solar system,” Tom Statler, Lucy mission program scientist, said in a press release. “The fact that each new asteroid we visit knocks our socks off means we’re only beginning to understand the depth and richness of that history. Telescopic observations are hinting that Donaldjohanson is going to have an interesting story, and I’m fully expecting to be surprised — again.”

In NoSQL database news, Arch Linux “is the latest Linux distribution replacing its Redis packages with the Valkey fork,” reports Phoronix.

Valkey is backed by the Linux Foundation, Google, Amazon Web Services, and Oracle, which the article points out is due to Redis’s decision last year to shift the upstream Redis license from a BSD 3-clause to RSALv2 and SSPLv1.

Valkey is replacing Redis in the Arch Linux extra repository and after a two week period the Redis package will be moved out to AUR and receive no further updates. Users are encouraged to migrate to Valkey as soon as possible.

“Russia is automating the spread of false information to fool AI chatbots,” reports the Washington Post. (When researchers checked 10 chatbots, a third of the responses repeated false pro-Russia messaging.)

The Post argues that this tactic offers “a playbook to other bad actors on how to game AI to push content meant to inflame, influence and obfuscate instead of inform,” and calls it “a fundamental weakness of the AI industry.”

Chatbot answers depend on the data fed into them. A guiding principle is that the more the chatbots read, the more informed their answers will be, which is why the industry is ravenous for content. But mass quantities of well-aimed chaff can skew the answers on specific topics. For Russia, that is the war in Ukraine. But for a politician, it could be an opponent; for a commercial firm, it could be a competitor. “Most chatbots struggle with disinformation,” said Giada Pistilli, principal ethicist at open-source AI platform Hugging Face. “They have basic safeguards against harmful content but can’t reliably spot sophisticated propaganda, [and] the problem gets worse with search-augmented systems that prioritize recent information.”

Early commercial attempts to manipulate chat results also are gathering steam, with some of the same digital marketers who once offered search engine optimization — or SEO — for higher Google rankings now trying to pump up mentions by AI chatbots through “generative engine optimization” — or GEO.
Our current situation “plays into the hands of those with the most means and the most to gain: for now, experts say, that is national governments with expertise in spreading propaganda.”

Russia and, to a lesser extent, China have been exploiting that advantage by flooding the zone with fables. But anyone could do the same, burning up far fewer resources than previous troll farm operations… In a twist that befuddled researchers for a year, almost no human beings visit the sites, which are hard to browse or search. Instead, their content is aimed at crawlers, the software programs that scour the web and bring back content for search engines and large language models. While those AI ventures are trained on a variety of datasets, an increasing number are offering chatbots that search the current web. Those are more likely to pick up something false if it is recent, and even more so if hundreds of pages on the web are saying much the same thing…

The gambit is even more effective because the Russian operation managed to get links to the Pravda network stories edited into Wikipedia pages and public Facebook group postings, probably with the help of human contractors. Many AI companies give special weight to Facebook and especially Wikipedia as accurate sources. (Wikipedia said this month that its bandwidth costs have soared 50 percent in just over a year, mostly because of AI crawlers….) Last month, other researchers set out to see whether the gambit was working. Finnish company Check First scoured Wikipedia and turned up nearly 2,000 hyperlinks on pages in 44 languages that pointed to 162 Pravda websites. It also found that some false information promoted by Pravda showed up in chatbot answers.
“They do even better in such places as China,” the article points out, “where traditional media is more tightly controlled and there are fewer sources for the bots.” (The nonprofit American Sunlight Project calls the process “LLM grooming”.)

The article quotes a top Kremlin propagandist as bragging in January that “we can actually change worldwide AI.”

About one sixth of global cropland is contaminated by toxic heavy metals, researchers have estimated, with as many as 1.4 billion people living in high-risk areas worldwide. From a report: Approximately 14 to 17% of cropland globally — roughly 242m hectares — is contaminated by at least one toxic metal such as arsenic, cadmium, cobalt, chromium, copper, nickel or lead, at levels that exceed agricultural and human health safety thresholds.

The analysis, which was conducted by the American Association for the Advancement of Science (AAAS) and published in the journal Science, collected data from more than 1,000 regional studies across the globe, as well as using machine learning technology. Dr Liz Rylott, a senior lecturer in the department of biology at the University of York, who was not involved in the research, said: “These findings reveal the deeply worrying extent to which these natural poisons are polluting our soils, entering our food and water, and affecting our health and our environment. Often collectively called heavy metals, these elements cause a range of devastating health problems, including skin lesions, reduced nerve and organ functions, and cancers.”

Toxic metal pollution in soil originates from both natural and human activity. Contaminated soil causes significant risks to ecosystems and human health as well as reducing crop yields, jeopardising water quality and food safety owing to bioaccumulation in farm animals. Toxic metal contamination can persist for decades once pollution has been introduced into soil.
