I let the elder kid choose her lunch. She chose a pizza so huge that each slice is larger than her entire face. Needless to say, she needed a little help with it!

YouTubeTo celebrate the site’s 25th birthday this year, Wikipedia is encouraging/challenging people to read one Wikipedia article a day for 25 consecutive days. I felt that I could do one better than that: not only reading an article but – where I found one that was particularly interesting – to write a blog post or record a podcast episode for each of those days, sharing what I learned. For each entry, I’ll hit “random article” a few times until something catches my interest, start reading, and then start writing! Everything I’ve written below came from Wikipedia… so you should check other sources before you use it to do your homework. Happy birthday, Wikipedia!
Today’s random article: Cirrothauma
Today’s topic: Cirrothauma murrayi
My random landing page today is a genus for which there’s only a single species, so I hopped over to that species’ page.
And what a species!
This is the blind cirrate octopus (cirrothauma murrayi), a species found beneath the oceans all around the world but at such a depth that they’re not well-understood. We’re not even sure whether the specimens we’ve studied represent a single species or two separate species!
The Latin name comes from oceanographer John Murray, best known for his Challenger Expedition from 1872–1876, but whose four month North Atlantic Oceanographic Expedition in 1910 – which he self-funded – was the first to find this unusual species. It was described by Carl Chun, whose previous claim to fame had been the discovery of the (also amazingly alien-looking) vampire squid, seven years earlier.
(The vampire squid is its own amazing thing: did you know that it turns itself inside out to evade predators, exposing the inner surface of its spiked tentacles? Also it can spit glow-in-the-dark mucus to dazzle an attacker.)
You can tell it’s a cirrate octopus by those fins on its head. Cirrates are one of the two major families of octopodes: they’re the ones that do have a pair of mini strands dangling off each sucker on each tentacle, but don’t have an ink sac. They’re also notoriously fragile, and when we’ve pulled them up for research purposes they’re often in poor condition by the time they’re on the surface… and that’s especially true for deep dwellers like the blind cirrate octopus.
As for blind: well – it’s got eyes… but those eyes don’t have lenses. As a result, they’re probably able to tell light from dark but probably can’t make out the particular shapes of objects. (This is a great example, contrary to claims of irreducible complexity in the eye by proponents of “intelligent design” of an eye with only some of the components that seem essential to a fully-functional organ that still provides value for its host!).
Speaking of which – do you know how cool the eyes of an octopus are?
- Like all cephalopods, they have no blind spot because their retina is in front of the nerve fibres instead of behind them.
- Like squid and possibly cuttlefish, they can differentiate the polarisation of light. (I believe that sheep and goats can, too!)
- Their pupils automatically rotate to stay horizontal, no matter which way up they are!
There’s some debate about whether or not octopodes and other cephalopods’ eyes evolved from a shared ancestor or are an example of convergent evolution, and the arguments for both are really interesting.
Of course, our friend the blind cirrate octopus is, umm… mostly blind. Very different from other octopodes.
As I said, we know so little about it! We don’t know what it eats (we think it probably eats whole shellfish). We don’t know how it breeds. We don’t know how commonplace it is or whether its environment is under threat.
But what we do know is that it’s a freaky-looking thing from way down deep. Thanks, Wikipedia, for telling me about this strange beast. Let’s see what you have to share with me tomorrow!
Self-clear area
I spent a while failing to interpret this sign. It seemed to be saying that if you didn’t clear your tray… then you’d get ketchup poured on your wrist?
It turns out there’s a baby bottle warming station on the other side of the bins.
(It is possible they my brain is struggling from a lack of sleep.)

Wikipedia @ 25: Milices Patriotiques
My random Wikipedia article of the day was Milices Patriotiques, who were a 22,000-strong communist group and part of the Belgian resistance in the Second World War. Which sounded really interesting, but their article was tragically short so that’s pretty much all I have to say about them!

Hold your head up high and show some PRIDE.
A Selfhosted Static Site Editor
My 12-year-old was interested in learning some HTML and CSS and making her own website. If she were anybody else I’d point her at something like Nekoweb as a starter host because their web-based (VSCode-based) “Nekode” text editor makes writing your first static site simple.
But I’ve got a NAS sitting at home on a fibre connection, so I figured: I might as well just host something similar here.
Here’s how I did it:
1. DNS
I pointed her domain at my static IP, plus a subdomain for the “backend” interface. Suppose her site would be at example.net (and www.example.net) with the admin interface at admin.example.net: my DNS configuration might look like this:
@ 10800 IN A 172.66.147.243 www 10800 IN CNAME example.net. admin 10800 IN CNAME example.net.
2. Caddy
I’ve got a Caddy webserver acting as a static server and a reverse proxy already, so I just added a new static site with a configuration like this:
example.net, www.example.net { root /volumes/example.net/public encode gzip templates file_server }
templates directive means that, if/when she wants to, she could use Caddy’s built-in SSI-like
features. Or if she decides someday she’d prefer a static site generator then I can sort her out with shell access or something.
It probably wouldn’t be much harder to set up something like this from scratch on e.g. a Raspberry Pi: Caddy’s fast and easy to get set up.
3. Editor
I used the OpenVSCode Server Docker image to provide a browser-based VSCode interface in which she could edit HTML, CSS and JavaScript and drag-drop files from her local machine. I’m using Unraid on my NAS so I didn’t have to think much about running a new Docker container, but I guess that if I did then I’d have typed something like:
docker run -d \ # 7890 is the port on my NAS that I'll proxy Caddy to: -p 7890:3000 # /mnt/user/example.net is the path on my NAS; # /example.net is where it'll appear within VSCode: -v "/mnt/user/example.net:/example.net" \ # this tells OpenVSCode-Server to mount the directory to begin with: -e OPENVSCODE_SERVER_ROOT=/example.net \ gitpod/openvscode-server
Now all I needed to do was point Caddy at it. For the time being I simply restricted access to only “computers on my local LAN”, but it’d be easy enough to add authentication using basic auth and/or client certificates if she wanted to be able to work on her site from elsewhere:
admin.example.net { # Restrict access to 192.168.* LAN: @allowed { remote_ip 192.168.0.0/16 } # Proxy permitted folks to the container: handle @allowed { reverse_proxy http://nas:7890 } # Block everybody else: handle { abort } }
That’s literally all it took to put together a web-based editing environment that publishes directly to a static website. And because it’s on my own infrastructure, it’d be trivially easy to modify it in the future if she decided to go in a different direction, e.g. a PHP site, or continuous deployment from a repo, or static site generation from a shell.
That’s all!
Here’s a test site I threw together using exactly this stack, demonstrating the entirely browser-based editing workflow (not shown is drag-and-drop to upload, but I promise that works too!):

Wikipedia @ 25: Jim Marshall
Today‘s random Wikipedia article was Jim Marshall (photographer). I enjoyed reading about him and even looked up some of the many photographs that he took of musicians in the 60s and 70s, but decided that because I was literally just writing about a photographer that I learned-about on Wikipedia, it probably wasn’t the time to write about another!
But here’s a fact for you: Jim Marshall was the official photographer for the Beatles‘ final concert in San Francisco’s Candlestick Park, and he was head photographer at Woodstock. There we go; that’s my Wikipedia article of the day!
F-Day plus 97
It’s been 97 days since our house flooded and we had to evacuate. We’re now living medium-term in a “chicory house” a few minutes drive away, but there’s still plenty of reason for us to return frequently to the disaster site that is our actual house.
Today, for example, JTA and I went to show around some contractors who will eventually, we hope, be able to install new floors, skirting boards, remove and replace a wall, rebuild the kitchen, fix the electrics…
It’s been over three months since we had to move out. With the drying-out complete, it’s finally time to begin planning to start scheduling the start of the repair work that needs doing. What a painfully-slow process!
The day after the flood water receded, I took this photo while we were assessing damage – you can see the tide marks left by the water:
That picture shows part of our piano, which took in a lot of water and was significantly damaged. It’s off at a nice piano hospital right now being repaired, and I miss it much more than I expected.
After playing maybe ten minutes a day almost every day for years, I routinely get up from my desk to stretch my legs or heat up my lunch and my fingers itch to plink-plonk away at it. Of all the hundred inconveniences of our temporary living situation and everything that goes along with it, that’s the one that bites most-frequently. It’s a strange sensation.
But all the builders and the insurance company and everybody else seem confident that they can get us back into our home in the Autumn, and certainly by Christmas, so there’s something to look forward to. A light at the end of the tunnel.

Today’s random article: Karsh (crater)
Today’s topic: Yousuf Karsh
The planet Mercury is covered with impact craters, which isn’t surprising because it has no atmosphere to slow down incoming meteors nor significant active tectonic or erosion processes to conceal them once they’re created. In 2015 the IAU ran a competition to name four such craters: the winning entries resulted in the naming of the craters Carolan, Enheduanna, Kulthum, Rivera, and Karsh.
This crater is named after Yousuf Karsh, who’s sufficiently famous that I’d actually heard of him, which was an unusual result from hitting “random article” on Wikipedia.
But in case you don’t know who Yousaf Karsh is – or if, like me, you just wanted to learn more about him – then you’re in luck!
Yousuf Karsh was an Canadian-Armenian photographer who took principally portrait photographs, some of which you’ve almost-certainly seen already. He photographed a huge number of famous and significant individuals of the 20th century. Like this one:
That photo, taken in 1941, is titled The Roaring Lion, and it’s got a story to it.
Winston Churchill posed for his photograph on his way out from delivering the “some chicken! some neck!” speech to the Canadian parliament (you can see his notes from the speech tucked into his jacket pocket). He had his trademark cigar in his mouth, but Karsh wanted it gone. He asked Churchill to remove it, but Churchill refused, and Karsh went ahead to take the photograph anyway. But then at the last second, Karsh said “Forgive me, sir” and snatched the cigar directly out of the Prime Minister’s mouth.
“By the time I got back to the camera, he looked so belligerent, he could have devoured me,” said Karsh later, of the expression on Churchill’s face. But it’s that expression that he captured with the camera, and that would go on to be described by the USC as a “defiant and scowling portrait [which] became an instant icon of Britain’s stand against fascism.” Absolutely iconic.
Churchill himself said, after the picture was taken, that “you can even make a roaring lion stand still to be photographed.” Hence the portrait’s name.
Or how about this picture of the Marx Brothers in 1948:
.jpg)
Or how about this fantastic photo of the then Princess Elizabeth, aged 21 or 22, before her accession as Queen Elizabeth II:
Here’s some things I didn’t know about Yousuf Karsh, though:
Being born to ethnic Armenians in the Ottoman Empire could have been a death sentence in itself for young Yousuf. Ottoman and later Turkish Nationalist authorities and paramilitaries deported, confined, or murdered hundreds of thousands and quite possibly over a million Armenians, who they saw as a threat to their national identity (among other candidate causes).
Karsh and his family travelled with a Kurdish caravan to Aleppo in Syria in 1922, and a year later his parents took advantage of a humanitarian scheme to transport displaced Armenians to live with relatives in Canada: the then 15-year-old who “spoke little French, and less English” and “had no money and little schooling” moved half way around the world to live with his uncle.
Yousuf’s uncle was a photographer and taught him the essentials of early-20th-century photography technology and techniques, before sending him to apprentice in Boston under John H. Garo, a fellow Armenian whose studio hosted the still-running Boston Camera Club. He worked in the USA for a time then returned to Canada, opening his own studio in 1932. When his brother Malak was able to join him in Canada in 1937, Yousuf helped Malak break into a career in photography too: a career that would probably have been better-known were it not for being in the shadow of his older brother!
I don’t know whether he’d care about having a crater named after him or not. But he’d probably have been more proud of the legacy that lives on in the Karsh Award, given every alternate year by the City of Ottawa for outstanding artistic work in a photo-based medium.
Bloomscrolling & Agentic Intelligence

…
A lot of the AI bubble – and that’s what it is, for all there are useful things inside there – is based on “Invest now, because when it works it’ll be fantastic!” rhetoric that’s like investing in a mainframe company in the late 60s on the basis that smartphones will take over the world. We’re moving a lot faster than mainframes went to PCs, but it’s important to invest in the things you can do with the system that work *now*.
There isn’t a good consumer use for AI right now. ChatGPT is a terrible source of information, confidently wrong in a way that sounds human enough to cause delusion and psychosis.
Things that AI/LLM tech is good for right now – pattern matching, repetitive tasks, logic flow – have some great business cases (It’s made some amazing breakthroughs in satellite and medical imagery, it’s got a bright future in automated transcription), and I think there’s a good case for it in content moderation (Yeah, it’s not great at it, but given the sick shit content mods on Facebook have had to deal with has given them cPTSD, I strongly believe it should be a machine job). It’s use for writing, music, translation, or art is still at the very least questionable and at the most utterly immoral.
…
Well-said, Aquarion!
The current generation of Generative AI isn’t useless. But its uses are quite specific and it certainly does more-harm-than-good that it’s promoted as an “everything” solution to every problem. I’ve used some form of agentic coding for several years, mostly of the “spicy autocomplete” variety1, and I mostly agree with Aquarion’s observations.
The whole post is an enjoyable tale.
Footnotes
1 My experiments with “vibe coding” have shown me that AI working alone can produce usually-functional code to specification, but that code is often of low quality and rarely maintainable, even by the AI.

Today’s random article: Here & Now (Pop Shuvit album)
Today’s topic: Necker Island (Hawaii)
As I observed… what…? 15 years ago, it’s easy to get lost down a series of Wikipedia links and have to use the back button to remember how you got there. That’s very much what happened to me today.
My random article for the day was about Here & Now, the second album of Pop Shuvit, a Malaysian hip hop/nu metal band most-active from around 2002 to 2011. I listened to the album; the title track’s pretty good, and I enjoyed Old Skool Rocka and Put ‘Em Up too.
The band take their name from a skateboarding trick called a pop shove-it, presumably using the different spelling to aid their ability to protect their copyright on it.
And this is the point at which I briefly got lost in the depths of Wikipedia’s article about skateboarding. A pop shove-it, you see, is apparently a combination of an ollie and a shove-it, which still sounded like a foreign language to me, so I had to read up on both. Here’s what I learned:
- An ollie is when you stomp down on the back of the board to make it jump, while sliding the front foot forward from the midpoint to keep it somewhat-level and stop it flipping “over”. This results in the entire board jumping while remaining almost-horizontal, while the skater flies just above it.
- A shove-it is when you rotate the board 180° laterally, so that the “back” end of the board becomes the “front” and vice-versa: so the board ends up landing and its wheels roll the opposite direction they did at the start of the trick, but the board and skater carry on moving forwards. It’s done by giving the board a bit of a kick to start it rotating and then landing on it with enough pressure to stop it rotating again.
That’s a terrible explanation. Here’s a terrible diagram from Wikipedia that probably doesn’t help either: (you’ll want to find a video if you really want to understand it, but that goes beyond what’s available on Wikipedia, so I’m not sharing it as part of this blog series!)
The pop shove-it was originally called the Ty hop, after its inventor Ty Page, a famous skateboard in the 1970s also known by the name “Mr. Incredible”.
I could list some of the other fifty-plus moves he’s credited with inventing (like the pay hop, daffy or yeah right manual, and the toe-spin 360), but it’d probably only be fun and interesting if I mixed-in a few fake ones I conceived of myself (like the nip trip, double pipe-tail, and the indo 180).
Skateboarding had been around since at least the 1950s and had exploded in popularity in the 1960s, but a major part of the reason Ty was able to invent totally new tricks in the 1970s was the result of a two new innovations that took off at that time:
- Polyurethane wheels, invented by Frank Nasworthy to supplant the use of hard steel wheels (commonly used by rollerskates at the time) or clay composite wheels. Steel wheels were fast and smooth-running, but because they’re hard they provide little grip, which makes stunts harder to control. Clay composite wheels were softer and easier, but wore out quickly, needing to be replaced after as little as seven hours of skating. Polyurethane gives a best-of-both worlds, giving a long-wearing but soft-enough-to-grip surface to the wheel from a material that was rapidly becoming cheaper to manufacture.
- The kicktail, invented (and patented) by Larry Stevenson, is the curved-up bit at the end of a board, so named because it originally only appeared at the back of a board (although Larry cleverly obtained a separate later patent on double-kicktails: one at the front and one at the rear – the front one is sometimes called a kicknose). A kicktail makes it much easier and safer to lift a board by stamping down on it, or else can make it possible to get more lift with a similar level of ease, compared to a completely flat board.
Ty Page helped promote the kicktail as part of the Makaha Team, sponsored by Stevenson’s company MAKAHA Skateboards. And here’s where I jumped into a whole different rabbithole.
At this point in history – as skateboarding was just beginning to come into its own as a sport – there was an enormous intersection between surfboarders and skateboarders, many of whom would surf when weather and tide conditions were right and skate when they weren’t.
Larry Stevenson was such an individual. On his way to his deployment in the Korean War, he stopped at Hawaii where he found a particular beach to be excellent for surfing. That beach, which would eventually give its name to his company, was at the town of… Mākaha.
One thing I found interesting while reading about Mākaha is that it’s the home of Kāne’āki Heiau, Hawaii’s most-completely restored heiau. Heiau are temples of the indigenous religion of Native Hawaiians, a polytheistic and animistic belief structure itself seemingly related to earlier Māori practices brought over by Polynesian seafarers from 800 CE onwards.
According to tradition, heiau were built by menehune, mythological two-foot high dwarves who lived in the deep forests and hidden valleys, far from humans, and came out at night to build structures and dig fish ponds. The concept is comparable to the European idea of brownies or hobgoblins, in particular the pre-Christian idea of these spirits as being helpful to humans so long as they’re treated with respect.
Pressure from Christian missionaries in Hawaii from 1820 onwards led to the neglect and destruction of most heiau, except for the most-remote of them. One such remote temple was the standing stones on Necker Island (see: we got there eventually!).
Necker Island is named after Jacques Necker, France’s finance minister at the time that the first European explorer – Jean-François de Galaup – sighted the rock. We don’t know what ancient Hawaiian peoples called it, but reverse-engineering Hawaiian chants passed down by oral tradition that include descriptions of islands has led the Hawaiian Lexicon Committee to assign it the name Mokumanamana, which means “pinnacled island”.
We also don’t know when Necker Island was last inhabited, but it seems that its poor thin soil is likely to have prevented permanent settlement. However, there’s evidence that its caves were used for human habitation from time to time, and some have been used as tombs. Even landing on the island is difficult on account of its sheer stone cliffs around its edge (which is part of the rim of what was once a volcanic cone).
But do you know what archaeologists found on Necker Island, amongst the standing stones? Menehune figurines, carved out of basalt, one and a half to two feet tall. Tales in the oral traditions of the natives of the island of Kauaʻi describe Necker Island as the last refuge of the diminutive builders after they were chased off the main island by the newly-arrived Polynesians.
In the way that was long-traditional for European empires exploring the culturally-important sites of distant lands, many of the artefacts found on Necker Island aren’t there any more. But the standing stones are still standing, and human remains that were removed and put into a museum have been returned and re-buried, at least.
So that’s Necker Island! Which I learned about because Wikipedia randomly chose me an article about an album by a Malaysian hip hop band, whose name derives from a skateboarding trick that’s possible thanks to an invention by a man whose skateboarding company was named after a surf-friendly Hawaiian beach near a town that has ruins of a temple allegedly built my mythological dwarves who are said to have lived there. It’s been quite a journey! I wonder where tomorrow’s will take me.
