(no, this isn't a blog post about Joy Division songs)

Last time I wrote about Interzone, I was discussing issue #294, the first published under new management in a paperback-sized format ("JB6"). The format and presentation of the magazine was fantastic: it fit in a lot of my pockets, and was packed with 15 stories as well as the regular columns, in full colour with fantastic layouts and illustrations. Sadly there was only one more physical issue before Interzone was forced to become a digital-only publication.

I don't want to dwell on the sad necessity to move to digital. Interzone continues on, celebrating the milestone issue #300 in 2024. Subscriptions are managed via Patreon. Issue #305 just came out.

Instead I wanted to write a small bit about how I engaged with the paper magazine, and the difficulties I've had trying to engage with not just Interzone but any magazine-style publication in a digital context.

With most fiction, I read linearly: start the beginning and read to the end, in order. That works well for me with e-readers. But for magazines (and most non-fiction) I don't, I jump around: usually starting with the table of contents, I might pick a short column to start, or jump into the middle of the "book reviews" section to read about a specific book. I might skip sections entirely. I find it very difficult to read like this with an e-reader. I think this is partly because I reference the depth of the paper book or magazine, its thickness, to orient myself. But it's also partly the limitations of e-ink.

For print-Interzone, I used to start by inserting a small piece of paper inside the cover (the delivery slip was ideal). On this I listed the stories within and ticked them off when I read them (sometimes I double-ticked if I really liked a story). That helped me to remember, perhaps months or years later, whether I'd read all the stories or not, and which I liked. I could do something similar on some e-readers: the Remarkable for instance. But it's far from convenient to do on most e-ink devices.

Interzone digital is available as both ePUB, the most common format for e-books, and PDF. For reading on my regular Kobo e-reader, PDFs don't work very well at all. I think this is generally true of most e-readers.

Interzone was (and is) a well-designed magazine. The value of it was not just the content of the text, but the context: how the stories were presented; the accompanying art (most often colour in recent decades), but also the typesetting. ePUB doesn't specify much of that stuff exactly: it leaves that up to the client and the client's preferences. And there's a lot of advantages to that: Prefer a different font face or size? No problem. And most importantly for accessibility: If reading in ePUB makes Interzone available to more readers then that's a great thing. But sadly a lot is lost, IMHO.

The solution I'm trying is to read the PDF version on the iPad Mini I resurrected earlier in the year. Despite being an Internet tablet, since it's not really usable for browsing the web anymore it's strangely still a distraction-free device. In fact it's pretty much single-purpose for reading Interzone and the odd other book which benefits from being read as PDF. I can appreciate the stylistic choices made in the page-setting as they were intended; I can quickly jump around the issue without waiting for an e-ink refresh; I get full colour; and whilst it would be tiring to read for a long time on the iPad screen, for the length of articles or stories in a magazine, this isn't a problem.

It's not a solution for tracking what I've read (that version of ipadOS is too old to support clumsily scrawling on PDF pages with your fingers, at least in the Books app) but it otherwise seems to work well, so I'll see how it goes.

I used to ice skate as a teenager but I stopped at University. I tried to pick it back up in 2024 but had to stop when I got ill. I restarted in 2025, initially with a weekly skate session but last month I started group hockey skate lessons.

I've been skating in a pair of Bauer¹ Nexus N77s that I bought 7 years ago on a work trip to Toronto. These did a great job of getting me back into the hobby for 6 years but recently I felt it was time to step up to a better quality pair. Despite being a size down from my shoe size, the Nexuses are too large: I had been compensating with thick socks but still struggling to get the boots tight enough. I'd have to wear gloves to lace up because I'd cut my hands pulling the laces otherwise.

After too long researching/deliberating/kvetching (very much on trend for me) I upgraded to Bauer Vapor Fly30s another half-size down (and nearly ten times as much). The fit is much better, in almost every respect. They actually go on easier and I don't have to tear my hands tightening the laces. They feel like a natural extension of my feet. I seem to be using a different set of muscles to skate, so the first few sessions were very fatiguing, but that settled. The Vapor line is speed-oriented, which I thought would fit my skate style best.

I have unfortunately gained a common problem: arch pain. More precisely, my navicular bone seems to be quite prominent², and that part is pressing uncomfortably into the boot. Boots typically take a few sessions to break in, but after 7-8 sessions the pain was getting to the stage that I couldn't skate for a full session without being in agony.

The last time I skated I tried to throw everything at the problem: I'd had the skates baked³; bought some orthotic insoles; then some "Bunga" pads over the sore bit and an attempt to more loosely tie the laces over the affected area. I tried a ten minute skate, and it seemed a bit better.

I then tried experimentally to swap back to my old skates, and I felt like Bambi: I just couldn't do it! They didn't press on the navicular, and they're softer so you can compensate for the size with tight lacing, but I had no confidence in them, I couldn't lean into the turns. They just felt weird. I realised there's no way back.

I switched back to the fly30s, adjusted the bunga pad positioning, tweaked the lacing and went back on for about 40 minutes. It went well: the rink was quiet, it was cool whilst we had a heat wave outside, so I worked up a sweat. By the end there was some discomfort, but not too much, and I think partly the area is currently sensitive so just about anything will cause discomfort. Fingers (or toes) crossed that I've mitigated the problem! If not, it might be time to try a punch out.

I bought a new synth! Kind-of.

I've traded my Minilogue-XD (full-size version with integrated keyboard) for the desktop/modular alternative.

Why? Partly, because it fits on my desk better. Partly, because it changes the way you engage with the instrument. It makes a huge difference: the ivory keys come with so much cultural precedent. The module version of the synth gains a switch that lets you use the 16 sequencer step buttons as note inputs, so you can still play the thing solo. But the emphasis moves away from note generation and more firmly towards tone.

Both versions have a lovely stained wood back, which you never see; the modular one has a hint of that at the front as well (which you do see).

I plan to eventually buy a MIDI keyboard that could drive it, and other things: possibly an Arturia KeyStep or Minilab, but there's no rush on that.

(It's about time I recorded and shared something I produced on this)

My youngest daughter and I recently started playing the tabletop game HeroQuest. Specifically, the recently-issued, cut-down variant HeroQuest: First Light. This is quite advanced for her age, and I'm a little surprised she's taken to it, but she's really loving it, It's pushed her to read bits of lore on cards and quest books that is way above her expected reading level, and we've been exercising her maths by adding up the gold we find on our quests and calculating what the heroes can buy with it in the store afterwards.

Originally from 1989, Hasbro re-issued HeroQuest in 2020. I read about it at the time but didn't buy it. I wasn't sure who I would play it with. It also seemed expensive to me. It probably wasn't unusually expensive in 2020, nor now, for the sheer volume of finely-sculpted miniatures included. I also knew I had the original game in the loft, and I wasn't that keen on buying something I already had, although untangling the contents from several similar boxed games would take me many hours, and I wasn't sure how much of the game I would find.

First Light was compelling because it is much, much cheaper than the full remake, so I was happy to take a punt. It's cheaper because it doesn't have any plastic monsters or furniture: instead cardboard cut-outs that stand up on plastic stands. For us, that is a significant drawback: 3D miniatures are much more immersive, But I can re-use the plastic miniatures I can find from the original game. First Light has a newly written adventure, better suited to beginners than the original game.

The re-issue(s) have new art and new model sculpts that look fantastic. They've changed anything which tied into Games Workshop's IP and I'm really happy about that. They've made an effort to add women, almost entirely absent from the original. I'm certain my daughter wouldn't have tried it otherwise.

It's been ten years since I configured mount on demand backups to reduce the risk of my backups being zapped by mistake. Way back then I wanted to go one step further and use dedicated mount namespaces for backup jobs, but systemd didn't provide the necessary support (and still doesn't, despite the promisingly-named JoinsNameSpaceOf= configuration option.)

I recently updated my setup to achieve this by hand. All backup jobs now have an extra pre-start instruction ExecStartPre=mkbackupns which runs a shell script to either set up a persistent mount namespace, or exit quietly if it already exists.

#!/bin/bash
set -euo pipefail

nsdir=/var/namespaces
nsfile=$nsdir/backup
nsfilex="$(echo $nsfile | sed 's#/#\\/#'g)"

private_propagation() {
    findmnt -o+PROPAGATION "$nsdir" | grep -q private
}
nsfs_is_mounted() {
    test "nsfs" = "$(awk "/$nsfilex/ { print \$3 }" /proc/mounts)"
}

if ! nsfs_is_mounted; then

    if ! private_propagation; then
        mkdir -p "$nsdir"
        mount --bind --make-private "$nsdir" "$nsdir"
    fi

    touch "$nsfile"
    unshare --mount="$nsfile" true

    nsenter --mount=/var/namespaces/backup mount /dev/phobos_backup/backup /backup
fi

I should note that I don't have the backup filesystem described in /etc/fstab to reduce the risk of it being mounted errantly in the main namespace.

The other change is to prefix an invocation of nsenter for every backup job command. E.g.:

ExecStart=/usr/bin/nsenter \
        --mount=/var/namespaces/backup \
        borgmatic -v 1 prune create

next steps

My backup scheme has lasted a decade with few tweaks (I moved it to Borg in 2020) which I am very grateful for. I want reliable, boring and robust.

Persistent mount namespaces are a lot less convoluted if you have a persistent process to associate them with. I didn't, but a subsequent improvement I am making is introducing one, so I will likely simplify the above accordingly.
