Geohashing expedition 2024-10-22 51 -1

This checkin to geohash 2024-10-22 51 -1 reflects a geohashing expedition. See more of Dan's hash logs.

Location

Harcourt Hill Bridleway, between Cumnor and North Hinksey

Participants

Plans

I’m on sabbatical from work right now, so I’m hoping to be able to get out to this hashpoint while the kids are at school.

Expedition

After dropping the kids off at school, the geopup/hashhound and I set out for the hashpoint. Coming up the “short side” of the bridleway from Botley would be a shorter walk, but we opted to park in Cumnor and come up the “long side” of Harcourt Hill to avoid Oxford’s traffic (and the inevitable fee for parking on the city’s side of the hill).

Harcourt Hill (like my village of Stanton Harcourt) doubtless gets its name from the Harcourt Family, who supported William the Conqueror during his conquest of Great Britain back in 1066 and were ultimately granted huge swathes of land around this part of the world in recognition of their loyalty. To this day, you find “Harcourt” in a lot of place names in this neck of the woods.

The hashpoint was so easy to find, we almost walked right over it: it’s right in the centre of the footpath/bridleway. Even my dog, who often doesn’t like long walks or muddy paths, didn’t get a chance to complain before we got there. We arrived at 09:35 and took the requisite photos, which can be found below. We also kept a GPS tracklog and vlogged our experience, all of which you can see below.

I’ve not properly hashed in a long while, so it was great to get back out there!

A footpath becomes a zebra crossing despite there being no road to cross, just a lawn (probably there USED to be a road).
What’s the point of this crossing? Do rabbits pass very fast through this junction?

Bad Names for Servers

Six or seven years ago our eldest child, then a preschooler, drew me a picture of the Internet1. I framed it and I keep it on the landing outside my bedroom – y’know, in case I get lost on the Internet and need a map:

Framed child-drawn picture showing multiple circles, connected by lines, each with a number 0 or 1 in it.
Lots of circles, all connected to one another, passing zeroes and ones around. Around this time she’d observed that I wrote my number zeroes “programmer-style” (crossed) and clearly tried to emulate this, too.

I found myself reminded of this piece of childhood art when she once again helped me with a network map, this weekend.

As I kick off my Automattic sabbatical I’m aiming to spend some of this and next month building a new server architecture for Three Rings. To share my plans, this weekend, I’d been drawing network diagrams showing my fellow volunteers what I was planning to implement. Later, our eldest swooped in and decided to “enhance” the picture with faces and names for each server:

Network diagram but with entities having faces and named Chungus, Atul, Summer, Gwen, Alice, Astrid, and Demmy.
I don’t think she intended it, but she’s made the primary application servers look the grumpiest. This might well fit with my experience of those servers, too.

I noted that she named the read-replica database server Demmy2, after our dog.

French Bulldog with her tongue sticking out.
You might have come across our dog before, if you followed me through Bleptember.

It’s a cute name for a server, but I don’t think I’m going to follow it. The last thing I want is for her to overhear me complaining about some possible future server problem and misinterpret what I’m saying. “Demmy is a bit slow; can you give her a kick,” could easily cause distress, not to mention “Demmy’s dying; can we spin up a replacement?”

I’ll stick to more-conventional server names for this new cluster, I think.

Footnotes

1 She spelled it “the Itnet”, but still: max props to her for thinking “what would he like a picture of… oh; he likes the Internet! I’ll draw him that!”

2 She also drew ears and a snout on the Demmy-server, in case the identity wasn’t clear to me!

Note #24772

Day #2 of my sabbatical had a morning in which I’ve mostly been roped into some charity-related digital forensics… until I got distracted by dndle.app, which apparently I accidentally broke yesterday! Move Fast and Fix Things!

Nex in CapsulePress

I’ve added Nex support to CapsulePress!

What does that mean?

Screenshot showing DanQ.me homepage via Nex, in Lagrange browser.
Here’s how nex://danq.me/ looks in my favourite desktop Gemini/smolweb browser Lagrange.

Nex is a lightweight Internet protocol reminiscent to me of Spartan (which CapsulePress also supports), but even more lightweight. Without even affordances like host identification, MIME types, response codes, or the expectation that Gemtext might be supported by the client, it’s perhaps more like Gopher than it is like Gemini.

It comes from the ever-entertaining smolweb hub of Nightfall City, whose Web interface clearly states at the top of every page the command you could have run to see that content over the Nex protocol. Lagrange added support for Nex almost a year ago and it’s such a lightweight protocol that I was quickly able to adapt CapsulePress’s implementation of Spartan to support Nex, too.

require 'gserver'
require 'word_wrap'
require 'word_wrap/core_ext'

class NexServer < GServer
  def initialize
    super(
      (ENV['NEX_PORT'] ? ENV['NEX_PORT'].to_i                           : 1900),
      (ENV['NEX_HOST']                                                 || '0.0.0.0'),
      (ENV['NEX_MAX_CONNECTIONS'] ? ENV['NEX_MAX_CONNECTIONS'].to_i : 4)
    )
  end

  def handle(io, req)
    puts "Nex: handling"
    io.print "\r\n"
    req = '/' if req == ''
    if response = CapsulePress.handle(req, 'nex')
      io.print response[:body].wrap(79)
    else
      io.print "Document not found\r\n"
    end
  end

  def serve(io)
    puts "Nex: client connected"
    req = io.gets.strip
    handle(io, req)
  end
end
This is genuinely the entirety of my implementation of my Nex server, atop CapsulePress. And it’s mostly boilerplate.

Why, you might ask? Well, the reasons are the same as all the other standards supported by CapsulePress:

  1. The smolweb is awesome.
  2. Making WordPress into a CMS things it was never meant to do is sorta my jam.
  3. It was a quick win while I waited for the pharmacist to shoot me up with 5G microchips my ‘flu and Covid boosters.

If you want to add Nex onto your CapsulePress, just git pull the latest version, ensure TCP port 1900 isn’t firewalled, and don’t add USE_NEX=false to your environment. That’s all!

Zero

✅ Inbox Zero
✅ Slack Notification Zero
✅ Assigned PR Reviews Zero
✅ Owned PRs… one, but it’s approved and just waiting for the right moment to merge

That’s got the be the first time in… literally years… that I’ve ended a workday so “clean”. Feels amazing.

There’ll be a mess again tomorrow, but hopefully only of a manageable size because I’m particularly clean to finish this week at “Work Zero”.

Facebook AI Training Opt-Out

And while we’re talking about AI.

It took a disproportionate about of time to find the right (tiny) link, but eventually I managed to opt-out of my content being used to train Facebook’s AI. They don’t make it easy, do they?

Google turns to nuclear to power AI data centres

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

“The grid needs new electricity sources to support AI technologies,” said Michael Terrell, senior director for energy and climate at Google.

“This agreement helps accelerate a new technology to meet energy needs cleanly and reliably, and unlock the full potential of AI for everyone.”

The deal with Google “is important to accelerate the commercialisation of advanced nuclear energy by demonstrating the technical and market viability of a solution critical to decarbonising power grids,” said Kairos executive Jeff Olson.

Sigh.

First, something lighthearted-if-it-wasn’t-sad. Google’s AI is, of course, the thing that comes up with gems like this:

Google AI, confidently stating that the difference between a sauce and a dressing is that sauces add flavour and texture to dishes, while dressings are used to protect wounds. It goes on to say that a dressing should be large enough to cover a wound: a standard serving size is two tablespoons.
I’ve actually never seen Google do this shit, because I was fortunate enough to have dropped Google Search as my primary search engine long ago, but it hilari-saddens1 me to see it anyway. Screenshot courtesy @devopscats@toot.cat.
But here’s the thing: the optimist in me wants to believe that when the current fad for LLMs passes, we might – if we’re lucky – come out the other side with some fringe benefits in the form of technological advancements.

Western nations have, in general, been under-investing in new nuclear technologies2, instead continuing to operate ageing second-generation reactors for longer and longer timescales3 while flip-flopping over whether or not to construct a new fleet. It sickens me to say so, but if investment by tech companies is what’s needed to unlock the next-generation power plants, and those plants can keep running after LLMs have had its day and go back to being a primarily academic consideration… then that’s fine by me.

Of course, it’s easy to also find plenty of much more-pessimistic viewpoints too. The other week, I had a dream in which we determined the most-likely identity of the “great filter”: a hypothetical resolution to the Fermi paradox that posits that the reason we don’t see evidence of extraterrestrial life is because there’s some common barrier to the development of spacefaring civilisations that most fail to pass. In the dream, we decided that the most-likely cause was energy hunger: that over time, an advancing civilisation would inevitably develop an increasingly energy-hungry series of egoistic technologies (cryptocurrencies, LLMs, whatever comes next…) and, fuelled by the selfish, individualistic forces that ironically allowed them to compete and evolve to this point, destroy their habitat and/or their sources of power and collapsing. I woke from the dream thinking that there’d be a potential short story to be written there, from the perspective of some future human looking back on the path of the technologies that lead them to whatever technology ultimately lead to our energy-hunger downfall, but never got around to writing it.

I think I’ll try to keep a hold of the optimistic viewpoint, for now: that the snake-that-eats-its-own-tail that is contemporary AI will fizzle out of mainstream relevance, but not before big tech makes big investments in next-generation nuclear, renewable, and energy storage technologies. That’d be nice.

Footnotes

1 Hilari-saddening: when you laugh at something until you realise quite how sad it is.

2 I’m a big fan of nuclear power – as I believe that all informed environmentalists should be – as both a stop-gap to decarbonising energy production and potentially as a relatively-clean long-term solution for balancing grids.

3 Consider for example Hartlepool Nuclear Power Station, which supplies 2%-3% of the UK’s electricity. Construction began in the 1960s and was supposed to run until 2007. Which was extended to 2014 (by which point it was clearly showing signs of ageing). Which was extended to 2019. Which was extended to 2024. It’s still running. The site’s approved for a new reactor but construction will probably be a decade-long project and hasn’t started, sooo…

Note #24735

You know that you REALLY needed that coffee when you:

1. get out a mug,
2. turn on the coffee machine,
3. load the dishwasher while you wait for the coffee machine to warm up,
4. can’t find your mug any more, oh shit it’s in the dishwasher 🤦

eBay Balance

eBay UK have changed their terms to (a) remove seller fees for most private sellers, but (b) instead of paying-out immediately, payouts are four times a year (or on-demand).

That sounds like they’re trying to keep money in their ecosystem. The hope is, I guess, that by paying sellers in virtual “eBay Pounds” rather than actual money in the first instance they’ll encourage those sellers to become buyers again (either of other listings, or of eBay’s postage and other services). You can cash out anytime you like, but you can never leave.

You see the same technique used e.g. by the National Lottery, who pay out “small” winnings into your online account, knowing that the vast majority of winnings are on the order of only a few times more than the value of a ticket, and so players will be more-likely to “re-invest” if they’re not paid-out directly.

Or maybe I’m just being cynical.

Sick words

This evening I pushed against my illness-addled brain to try to sit in on the fortnightly Zoom call with the Three Rings dev team. Unfortunately it seems like the primary symptom of my cold is an inability to string words together.

At one point, I apologised to by colleague “Beff” (I meant “Bev”, but I had just been talking about “Geoff”) that I couldn’t work out how to stop “scaring my screen” (well, I suppose Halloween is coming up…). Then, realising my mistake, explained that it was a bit of a “ting-twister”.

I should just go to bed, right?

Firsts and Lasts

A lot of attention is paid, often in retrospect, to the experience of the first times in our lives. The first laugh; the first kiss; the first day at your job1. But for every first, there must inevitably be a last.

I recall a moment when I was… perhaps the age our eldest child is now. As I listened to the bats in our garden, my mother told me about how she couldn’t hear them as clearly as she could when she was my age. The human ear isn’t well-equipped to hear that frequency that bats use, and while children can often pick out the sounds, the ability tends to fade with age.

Face of a bat, hanging upside-down.
“Helloooo? Are you even listening to me?”

This recollection came as I stayed up late the other month to watch the Perseids. I lay in the hammock in our garden under a fabulously clear sky as the sun finished setting, and – after being still and quiet for a time – realised that the local bat colony were out foraging for insects. They flew around and very close to me, and it occurred to me that I couldn’t hear them at all.

There must necessarily have been a “last time” that I heard a bat’s echolocation. I remember a time about ten years ago, at the first house in Oxford of Ruth, JTA and I (along with Paul), standing in the back garden and listening to those high-pitched chirps. But I can’t tell you when the very last time was. At the time it will have felt unremarkable rather than noteworthy.

First times can often be identified contemporaneously. For example: I was able to acknowledge my first time on a looping rollercoaster at the time.

The Tower of Terror, Camelot Theme Park, circa 1990s; a steel rollercoaster track dips in and out of a fibreglass castle structure.
The Tower of Terror at Camelot, circa 1994, was my first looping rollercoaster2. The ride was disassembled in 2000 and, minus its “tower” theming3lived on for a while as Twist ‘N’ Shout at Loudoun Castle in Ayrshire, Scotland before that park shut down. I looked at some recent satellite photography and I’m confident it’s now been demolished.
Last times are often invisible at the time. You don’t see the significance of the everyday and routine except in hindsight.

I wonder what it would be like if we had the same level of consciousness of last times as we did of firsts. How differently might we treat a final phone call to a loved one or the ultimate visit to a special place if we knew, at the time, that there would be no more?

Would such a world be more-comforting, providing closure at every turn? Or would it lead to a paralytic anticipatory grief: “I can’t visit my friend; what if I find out that it’s the last time?”

Footnotes

1 While watching a wooden train toy jiggle down a length of string, reportedly; Sarah Titlow, behind the school outbuilding, circa 1988; and five years ago this week, respectively.

2 Can’t see the loop? It’s inside the tower. A clever bit of design conceals the inversion from outside the ride; also the track later re-enters the fort (on the left of the photo) to “thread the needle” through the centre of the loop. When they were running three trains (two in motion at once) at the proper cadence, it was quite impressive as you’d loop around while a second train went through the middle, and then go through the middle while a third train did the loop!

3 I’m told that the “tower” caught fire during disassembly and was destroyed.
