A planet might orbit Alpha Centauri A: send Chrysalis there instead

21 August 2025

The planet’s existence — orbiting Alpha Centauri A, part of the nearest stellar system to the Sun — has not yet been confirmed. If there though, the body would be situated within Alpha Centauri A’s (AKA Rigil Kentaurus) habitable zone, a star similar to our Sun.

That could be a more “Earth-like” planet, certainly more so than any planets orbiting the third member of the Alpha Centauri trinary: red dwarf star Proxima Centauri.

If anyone is serious about sending a sixty-kilometre long, multi-generational spaceship, named Chrysalis, on a four-hundred year, one-way, journey to Alpha Centauri, then the would-be planet hosted by Alpha Centauri A would be a more sensible destination.

Once, that is, the planet is confirmed to exist, in-fact resides in Alpha Centauri A’s habitable zone, and is truly “Earth-like”, not just some rock with a slight atmosphere, and a bit of liquid water.

Future Boy, a book by Michael J. Fox, and a missing Gibson guitar

20 August 2025

Future Boy: Back to the Future and My Journey through the Space-Time Continuum, is a book written by American actor Michael J. Fox, of, of course, Back to the Future (BTTF) fame, in conjunction with TV and film producer, Nelle Fortenberry.

Fans of the 1985 time-traveller caper, and Fox himself, probably already know the story. Fox was also on the cast of TV sitcom Family Ties, and during the filming of BTTF, would shuttle back and forth between the sets of TV and film. TV during the day, film by night. If working two jobs each day was tiring, Fox sure as hell didn’t show it, as he seemed to do nothing but burst about the screen in BTTF.

Future Boy delves deeper into this story, through interviews with the cast and crew of both Family Ties and BTTF, and will be published on Tuesday 14 October 2025.

That’ll definitely be a red-letter day for BTTF aficionados.

And in other news, BTTF cast and crew are searching for the guitar, the Cherry Red Gibson ES-345 to be precise, which Marty McFly played when performing Chuck Berry’s Johnny B. Goode, at the Enchantment Under the Sea high school dance.

This is no publicity stunt (I don’t think). BTTF producers realised the iconic guitar was missing when they went to film the sequel, Back to the Future Part II, back in 1989.

They’re hoping to find it today, soon, this century, to coincide with the fortieth anniversary of BTTF, and the release of a documentary about the film, Lost to the Future, which I think goes to air later this year. Members of the cast, including Fox, Harry Waters Jr, Lea Thompson, and Christopher Lloyd, are among those who have issued an appeal for information in the search for the Gibson.

I’d forgotten 2025 was such a red-letter year in the history of BTTF. I think this calls for a screening this evening of BTTF.

The 2025 Australian Prime Minister’s Literary Awards shortlists

19 August 2025

Theory & Practice by Michelle de Kretser, winner of this year’s Stellar Prize, Highway 13 by Fiona McFarlane, and Juice by Tim Winton — which I’m presently reading — are among titles shortlisted in the fiction category of the 2025 Prime Minister’s Literary Awards.

Award categories also include non-fiction, Australian history, poetry, children’s literature, and young adult. Six-hundred-and-forty-five entries were received this year, indicating Australian writers are busy. The winners will be named on Monday 29 September 2025, at a ceremony in Canberra.

Microsoft sued over plans to discontinue Windows 10 support

16 August 2025

California based Lawrence Klein is attempting to sue Microsoft over its plan to discontinue support for the Windows 10 operating system (OS) come October.

The action is understandable from the point of view that a device apparently requires specific hardware for Windows 11 — the Windows 10 successor OS — to function. This hardware is not to be found on older devices, rendering them unusable if they can’t run Windows 10.

Klein says that the end of Windows 10 is part of Microsoft’s strategy to force customers to purchase new devices and to “monopolize the generative AI market.” Windows 11 comes with Microsoft’s suite of generative artificial intelligence software, including the chatbot Copilot. To run optimally, Microsoft’s AI needs a piece of hardware called a neural processing unit, which newer tablets, laptops and desktop computers have — and which the older devices do not.

Before I migrated to Linux Mint (LM) last year, I was regularly sent prompts by Microsoft urging me to install Windows 11. Evidently my device, which is three years old now, had the requisite hardware as I was told Windows 11 could operate on it.

While we’re talking of those nagging “upgrade” prompts, they’re one thing I certainly do not miss.

Of course Windows 10 will continue to work without the presently regular support updates, but I’d be reluctant in the extreme to use any Windows OS that was not supported. That would be putting any device at considerable risk.

While the switch to LM was quite the undertaking, and involved a few bumps early on, I’m pleased to be here, something I’ve said before. I’d encourage anyone still on Windows 10 to consider LM. It’s user-friendly, somewhat resembles Windows 10, and comes in several versions, meaning it’s possible to install on relatively old devices.

You’ll also escape the Windows hegemony, and have an OS that’s not half dependent on AI to work.

What if the dead do not want live in the eternal AI afterlife?

16 August 2025

Family members should have the ability to prevent the creation of AI generated likenesses of deceased relatives, says American legal scholar Victoria Haneman.

“Digital resurrection by or through AI requires the personal data of the deceased, and the amount of data that we are storing online is increasing exponentially with each passing year,” Haneman wrote.

Here’s something else to think about. I’m not sure if there are laws in any jurisdiction that cover this sort of situation.

Vale David Stratton, Australian film critic

15 August 2025

The family of the noted film critic announced his death, at age 85, yesterday, Thursday August 2025.

I used to do some film writing (I still do occasionally) but would never describe my efforts as critique. Nonetheless, I used to be invited to preview screenings and premieres, and from time to time Stratton would be present.

Stratton, together with long time collaborator Margaret Pomeranz, were recently inducted onto the Australian Film Walk of Fame, becoming the first non-actors to be accorded the honour. If that doesn’t speak volumes about the regard in which Stratton’s work was held, I don’t know what does.

A four-hundred year, one way, trip to Proxima Centauri? Is this sci-fi?

13 August 2025

A proposal to build a multi-generational spaceship — named Chrysalis — that’s nearly sixty-kilometres in length, and would spend four-hundred years travelling to the star presently closest to the Sun, Proxima Centuri, recently won first prize in the Project Hyperion Design Competition.

The vessel, which would be fitted out with tropical forests, schools, workplaces, libraries, and manufacturing facilities, among other things, could house over two-thousand people. Obviously some travellers on Chrysalis, would live their entire lives only on the gigantic ship.

So far, so good. Aside from the ethical matter of consigning your descendants to a life lived on a sixty-kilometre long tin-can, whether they like it or not. But the proposal becomes a little murkier when we learn the vessel’s precise destination:

Chrysalis is designed to house several generations of people until it enters the star system, where it could shuttle them to the surface of the planet Proxima Centuri b — an Earth-size exoplanet that is thought to be potentially habitable.

Proxima Centuri b is thought to be habitable? So to recap: someone wants to spend untold trillions of dollars building a massive spaceship, that will carry some two-thousand people, on a four-hundred year long, one way voyage, to a planet thought to be habitable?

Am I the only one who sees a problem with this?

Wouldn’t we first want to be one-hundred percent certain the planet in question, Proxima Centuri b, was in fact habitable, in Earth-analog fashion, before even drawing up blueprints for the vessel? Apparently not. Chrysalis‘ designers appear to be so confident Proxima Centuri b is fit for human habitation, they’re laying on shuttles to get people on the ground.

Doubtless passengers are relieved they’re not required to parachute to the surface.

Proxima Centuri b was discovered in 2016. The body is a super-Earth, meaning it is larger than our home planet, but still smaller than the likes of Uranus or Neptune. In addition, the planet is located in what is considered to be Proxima Centuri’s habitable zone. Planets within a star’s habitable, or Goldilocks zone, as Earth is in the Sun’s, are generally deemed to be conducive to life. Temperatures are neither too hot, nor too cold, and water can exist in liquid form.

But talk of Goldilocks zones usually applies more to G-type main-sequence stars, or yellow dwarfs, such as the Sun. Proxima Centuri is a red dwarf star, a rather different kettle of fish. I’m not even sure the term habitable zone should be uttered in the same sentence as red dwarfs.

I’ve written about these stars before. They fascinate me. As mentioned, one is the star nearest to us. They also live for trillions of years (compared to billions for many other stars, including the Sun). Red dwarfs will probably be the last stars shining in the universe.

But, as I’ve said previously, they’re not all that life-friendly, particularly for human life. As I’ve written this before, I’ll be succinct. Planets in the supposed habitable zones of red dwarfs, would be — on account of their relative closeness to the star — tidally locked. One side of the planet forever faces the star, and bakes, while the other, cloaked in perpetual darkness, freezes. Most hospitable.

Red dwarfs also emit powerful flares. The outlook would not be good for the inhabitants of a planet in the path of one of these stellar outbursts. Proxima Centuri b may be possessed of some sort of atmosphere, and water might be present, but the planet is no Earth.

What if, on reaching the distant planet, those aboard Chrysalis find it to be completely uninhabitable? Would they be able to return to Earth? No, because the journey is one way. Passengers would be on a multi-century trip to their deaths.

Of course, the Chrysalis project is hypothetical, but that doesn’t mean there isn’t merit in the idea. If the vessel is ever to be constructed, a more suitable destination planet, not just one thought to be habitable, needs to be chosen.

Steve Coogan, Rob Brydon, return for Northern Lights trip

12 August 2025

It seemed pretty clear 2020’s The Trip to Greece was the final jaunt for British foodies Steve Coogan and Rob Brydon. This after travels to the north of England, Italy, and Spain.

But now a new six-part series, The Trip To The Northern Lights, where the pair will venture around Scandinavia, starts production later in 2025, and presumably screens sometime in 2026.

The work of dredger boat operators is safe from AI technologies

12 August 2025

Writers, authors, proof readers, news analysts, reporters, journalists, and editors, are among occupations Microsoft sees as being vulnerable to AI technologies. A blogger, by the way, is each and every of those roles.

But that’s not all. Web designers, interpreters, historians, and political scientists, are in danger. Mathematicians even. The threat isn’t restricted to what might be called desk-bound occupations either. The roles of customer service reps, hosts, models, and telemarketers, are also on the line.

But there are some professions safe from AI (for now). These include hospital orderlies, motorboat operators, floor sanders, water treatment plant workers, and dredge operators.

Dredger boats often trawl through the waters of the lakes near where we stay on the NSW Central Coast. I was watching one such vessel earlier this year, and, ironically, speculated how the work could be carried out by an AI agent of some sort.

A sophisticated under water camera and sonar array, was part of what came to mind. Instead, it looks like the dredger boat crews will be with us for some time to come.

Enshittification, word of 2024, a book by Cory Doctorow 2025

11 August 2025

Enshittification: Why Everything Suddenly Got Worse and What To Do About It, by Canadian-British blogger, journalist, and author Cory Doctorow, will be published in October 2025.

Doctorow coined the word enshittification in 2022. Long story short, the neologism describes how online platforms go from being useful to useless, on account of the greed of their owners.

Facebook and Instagram are good examples of enshittification at work. Once both social networks were populated by content created by members. As time has passed though, much of what appears on these platforms is effectively advertising.

Enshittification was named the 2024 word of the year by Australia’s Macquarie Dictionary.
