Monthly Meanderings: March 2026

2026-04-01T00:00:00Z

Since last month’s update I’ve been unpleasantly reminded that I’m middle aged, through the medium of a dodgy knee. There’s nothing quite like not being able to stand up without groaning to underscore that you’re not young any more. The ongoing game of “will this seemingly mundane activity make my knee go funny again?” is a delight to play, too. I’m great at it.

Website updates

Two new blog posts this month: the longest way to represent a date is a short thought experiment on absurd date formats, and modern CSS is fun goes through some neat new CSS features I’ve used recently for this site.

I did some design tweaks this month: headers now have a blue background behind them¹, and a lot of components have been redesigned to have a consistent style. You can see that component in action in the new “now playing” widget I’ve added:

VersaEmerge — Redesign Me Fixed at Zero Scrobbled 2h 8m ago

Instead of each component defining its own styles (which were mostly copied and pasted), there’s now a single class that handles the drop shadow, border, background colour, and the optional title. It also applies a consistent format to elements that are clickable: they use the blue accent colour for their borders, and have a glow effect shown on hover.

The now playing widget is part of a larger bit of work I did on importing some music stats. I’m pulling in the data from my Navidrome instance. A new music page shows my most listened albums and artists. Navidrome doesn’t store a complete play history, just the last play and the count, so I can’t do “what I listened to last month” stats until next month.

Other projects

Other than a minor bug-fix update to contempt, my Dockerfile templating/updating tool, I’ve not done much on my other open source projects. I’ve got a bit more work to do finish migrating all my repositories from GitHub to my private Forgejo instance. I’ve also been thinking about mirroring my public repositories to Codeberg so there’s a non-GitHub way to access them.

Entertainment

I apparently only watched a single film in March:

The Substance

2026-03-18

I really didn’t get on with this. It’s too long for what it is, and over-the-top in a way that just didn’t work for me.

Demi Moore and Margaret Qualley were great, but nothing else really was. The cinematography and sound design were too affected, the plot was pretty shallow and obvious, most of the body horror fell into the uncanny CGI valley for me.

It’s not completely without merit: there were around 40 minutes in the middle where I was really into it, but that’s not really enough given it’s closing in on a 2.5 hour runtime.

There’s something to be said for the message it’s presenting about women in Hollywood, too, but it was very heavy handed. Dennis Quaid’s character is even called Harvey; it’s not so much a subtle nod as a sledgehammer to the face.

Instead of films, I’ve been watching a bunch of TV. After devouring The Pitt last month, I struggled to find something to fill the hole it left. I settled on catching up on Chicago Fire and Chicago P.D.. They’re both mostly about getting things done without personal drama becoming the primary focus. They’re not quite as grounded as The Pitt, but at least they’ve not completely gone off the deep end like 9-1-1 where the first responders end up in space somehow?

I’ve also watched the first two episodes of SNL UK. I didn’t have very high expectations, and it gave me a pleasant surprise. Both episodes so far have some hilarious sketches, and are obviously written by British comics with the typical darker, more sardonic humour that separates us from the USA.

Last but not least, board games! I spent a weekend at a tabletop/LAN event with friends, so got to physically play some games for a change. I also kept up with some turn-based games on Board Game Arena, as usual.

Around the web

Warranty Void if Regenerated

Some really cool speculative fiction about a future where all software is written by LLMs, and the social effects that may have. Unfortunately the story itself is written with an LLM, and that becomes painfully obvious about a third of the way in. By that point I was already hooked, though.

My 2-step process for AI-free blogging

Speaking of LLM-generated text, this short piece by Manuel Moreale made me laugh. I’m by no means anti-LLM, but I really hate people publishing the output like it’s their own work. It breaks the social assumption that the writer put more effort in than the reader, and makes me wonder how much is hallucinated.

25 Years of Eggs

An interesting applied use of coding agents. I’m a sucker for personal statistics. I have no explicit desire to keep my receipts, or generate graphs of my egg consumption, but seeing the graphs makes me question that. The journey to get there is a great read, too.

I made a one-page notebook

The clever paper folding is interesting, but I really like some of the small touches on the page. There’s a nice little “in reply to” callout providing context at the top of the page, you can click to rotate the image further down, and there’s a details element containing a textual version of it. It has that great ‘small web’ vibe of someone who really cares about what they’re doing.

Workers who love ‘synergizing paradigms’ might be bad at their jobs

I haven’t read the full paper, but the summary given by the article is equal parts interesting and amusing. They developed a “Corporate Bullshit Receptivity Scale”, what more is there to say?

It’s meant to resemble painter’s tape, but I’m not sure quite how well it works. ↩︎

Modern CSS is fun

2026-03-17T00:00:00Z

I’ve been doing a bunch of CSS tweaking recently, and keep being surprised by how nice modern CSS is to work with. As someone grey-haired enough to remember writing HTML without CSS, it’s amazing to think how far along web technology has come¹. I wanted to demonstrate some of the handy bits and pieces I’ve used recently.

:has

The :has selector allows you to effectively query for child elements. While a span will match a <span> within an <a>, a:has(span) will match an <a> that contains a <span>. This really shines when combined with more complex selectors, for example:

input {
    border-radius: var(--border-radius);

    &:has(+ .results:not(:empty)) {
        border-bottom-left-radius: 0;
        border-bottom-right-radius: 0;
    }
}

This is part of the styling for my film search box. When the search box is presented initially it has fully rounded corners. But when it is followed by a non-empty results element, it removes the rounding on the bottom corners so that the border continues in a straight line down into the results. You can see it in action below; just enter a few characters (like “the”) to get some results:

You could achieve the same effect by having JavaScript add a class to the <input> element, but I’ll take a CSS solution over a JavaScript solution any day.

Nested rules

You probably spotted this in the example above. It’s what finally made me switch from SCSS to plain CSS. If you have a rule for .foo and a rule for .foo .bar you can just nest them. Not only does it save repeating yourself an awful lot, it keeps everything organised nicely. For example, the CSS for my film list embeds looks like this:

a.film-list {
    display: grid;
    grid-template-areas: "header images" "description images" "meta images";
    grid-template-columns: 1fr auto;
    grid-template-rows: auto 1fr auto;
    row-gap: var(--small-space);

    @media (width <= 800px) {
        grid-template-areas: "header" "description" "images" "meta";
        grid-template-columns: 1fr;
        grid-template-rows: auto auto auto auto;
    }

    & + & {
        margin-top: var(--medium-space);
    }

    h3 {
        font-size: var(--font-size-xxlarge);
    }

    .description {
        /* ... */
    }
}

Everything is wrapped up in a single bundle, including the @media rules for changing the layout on smaller screens, the lovely little & + & rule that adds some extra margin if there are two lists in a row, etc. The & syntax refers to the parent selector, so & + & in this case is the same as a.film-list + a.film-list: it’s very handy! The best part about this is that it’s the exact same syntax as SCSS, so converting is easy². The styled element looks like this:

Watched films ranked

Every film I’ve watched since I started logging, ranked.

Obviously super subjective, and subject to change often and arbitrarily.

264 films

Media range syntax

Once again, you might have spotted this in the previous snippet. I’m not deliberately teasing things, I promise! Back in the day, you did media queries like so:

@media (min-width: 1000px) and (max-width: 2000px) {
    /* some rules that work for screens at least 1000px wide and at most 2000px wide */
}

I always hated this syntax. I always got muddled up as to whether I wanted “min” or “max”, and whether they were inclusive or not. It’s easy to reason through, but it never came naturally. Fortunately you can now just use ranges:

@media (1000px <= width <= 2000px) {
    /* some rules that work for screens at least 1000px wide and at most 2000px wide */
}

I find this style so much easier to write and understand.

Anchor positioning

Trying to dynamically position one element next to another used to exclusively fall within the purview of JavaScript. Fortunately anchor positioning fixes all this. I use this in the film search field I showed above:

.film-search {
    input {
        anchor-name: --film-search-box;
    }
    .results {
        position: absolute;
        position-anchor: --film-search-box;
        position-area: bottom center;
        position-visibility: always;
        width: anchor-size();
    }
}

This does lots of fun things. The .results element is anchored to the input field (via the --film-search-box name), and it’s positioned on the bottom, directly under the anchor. The position-area rule describes a 3x3 grid, with the anchor at the center, so top left would put it diagonally adjacent to the anchor. Next, position-visibility keeps the .results element visible when the anchor isn’t; otherwise when you scroll the anchor off the screen the results would immediately vanish. Finally, the special anchor-size() function makes the .results element take up the same exact width as the anchor.

All-in-all, this puts the results exactly where I want them, without having to deal with any JavaScript at all. I can see how it’d also be amazingly useful trying to do tooltips or other forms of ‘floating’ content too. You can even leave the positioning up to the browser, giving it hints about which order to try, or what property to optimise for (e.g. you can say “anchor to the left or right, whichever has more horizontal space”).

attr() function

This one blew my mind a little. In some of the elements on the site, I’ve added a little label to the top. It looks something like this:

It’s meant to just be a visual flourish, not a semantic title or anything, so I initially just added a ::before selector to each element, customising the content to have the right value. I didn’t like the duplication, though. Now, instead, I do this:

&::before {
    content: attr(data-title);
}

Each component defines its title in a data attribute: <div class="raised-box" data-title="an example">, and the attr function plucks it out and puts it in the content rule. It’s worth noting that this is only widely supported for the content rule, you can’t yet use it for colours or dimensions or other things. It still feels a bit magical, though. Like you’re making a reusable, customisable component with just HTML and CSS.

layers

I’d come across layers a few times, but I never found a need for them. It seemed like something you’d only really need with complicated design systems, or something. Then I had a problem and layers were the perfect solution!

The headings on this site have a whole bunch of CSS attached to them. Currently they look a bit like blue painter’s tape with handwriting on them. This style is applied to all headers, and then the various places that don’t want it had to manually reset everything. I got fed up with that, so decided to add a plain-header class which would “disable” the extra styling:

h2,
h3,
h4,
h5,
h6 {
    /* common styles for all headers, regardless */
    font-family: "Chris Hand", sans-serif;
    font-size: var(--font-size-xxlarge);
    color: var(--text-highlight-colour);
    margin: var(--medium-space) 0;
    line-height: 1;

    &:not(.plain-header) {
        /* do fancy stuff if it _doesn't_ have the .plain-header class */
        transform: rotate(-0.15deg);
        padding: var(--smedium-space);
        font-weight: 800;
        filter: drop-shadow(3px 3px 5px rgb(0, 0, 0));

        a {
            background: none;
            text-decoration-skip-ink: auto;
        }
    }
}

This might seem a bit backwards but I want the default to be styled, as those are far more common. I added this change, sprinkled around some “plain-header” classes, tidied up a lot of duplicate CSS, and things mostly worked. Mostly. Some things stopped working. In a few places the headers had slight tweaks, and they stopped working entirely.

It turns out in moving the rules from a plain h2 selector to a h2:not(.plain-header), I’d made them more specific. Previously a selector like h2.special would have been more specific, so its properties would override those from the less specific h2 selector. My first reaction was to try and hack around it. Changing all the overrides to body h2.special would make them more specific again, but I didn’t want to have to remember to do that forever more.

Instead, I defined some custom layers, and put the header definitions in one:

@layer reset, links, headings

@layer headings {
    h2,
    h3 {
        /* etc */
    }
}

The first @layer rule defines some layers that will be handled in a specific order: first the “reset” layer, then the “links” layer, then the “headings” layer, and then anything not in a layer after that. Rules in one layer don’t have to worry about beating the specificity of rules in another layer, because they’re handled separately.

Note that I couldn’t just put the headings in a layer and call it a day: their rules have to come after the CSS reset, and after the normal link styles, as headers have a bit of extra styling for nested links. If the CSS reset weren’t in a layer, then the * { margin: 0; padding: 0; } type reset would apply over the rules from the headings layer.

Using layers is definitely a bit fiddly, and is not necessary for a lot of sites, but it’s a much cleaner alternative to ugly specificity hacking.

Things I’m looking forward to

There are a few things that aren’t (widely) available yet, that particularly interest me:

sibling-index() and sibling-count()

These new functions are available in WebKit and Blink based browsers, but not Firefox. They give you the index of the element within its siblings, or the count of siblings. For the film list component above, I currently have this abomination for the overlapping posters:

&:nth-child(1) {
    z-index: 5;
    left: 0;
}
&:nth-child(2) {
    z-index: 4;
    left: calc(133px * var(--overlap) * 1);
}
&:nth-child(3) {
    z-index: 3;
    left: calc(133px * var(--overlap) * 2);
}
&:nth-child(4) {
    z-index: 2;
    left: calc(133px * var(--overlap) * 3);
}
&:nth-child(5) {
    z-index: 1;
    left: calc(133px * var(--overlap) * 4);
}

These could be replaced with something like:

z-index: calc(1 + sibling-count() - sibling-index());
left: calc(133px * var(--overlap) * (sibling-index() - 1));

As an added bonus, it would scale to any number of posters. index being 1-based not 0-based is a bit unfortunate as it makes using it in calculations awkward (see 1 offset in both of those rules!), but it’s leagues better than writing 5 separate rules.

random()

Currently only available in Safari. There are a few places where I’d like to have slight random variations of the style. Things like elements that are rotated slightly for aesthetics; they look a bit silly if they’re all identically positioned. I also randomise the icons and positions of my rating stars to break up the visual monotony. Here are a few examples:

Currently I do the stars by hardcoding a bunch of classes and having the backend randomly apply one when it generates the markup for stars. Being able to do it in CSS would be great, though.

Mixins

This one’s so far off it’s not even listed on caniuse.com yet. Mixins are another handy feature of SCSS, that allow you to define reusable blocks of rules, then import them when needed:

@mixin fancy-background {
    background: /*...*/;
}

.some-element {
    @include fancy-background;
}

#other-element {
    @include fancy-background;
}

This would be particularly useful if you can’t easily control the markup to add classes to everything. For example, my footnotes are rendered by a markdown plugin, and don’t easily have a way to add extra classes to them. To style it the same as another element, I currently duplicate a bunch of rules between them both. Mixins would allow me to define those rules once, and then import them in both places.

Aside from JavaScript, which seems to just endlessly reinvent new frameworks and ways to make the most sprawling dependency tree possible. ↩︎
It also means that if your website’s syntax highlighting library doesn’t seem to understand nested rules, you can just pretend your perfectly valid CSS is actually SCSS and it’ll magically work. Grumble, grumble. ↩︎

Thinking more about backups

2025-11-01T00:00:00Z

The Backblaze logo

Almost a year ago I wrote about how I do backups with Restic and Hetzner. That system has been ticking along well ever since, but recently I had some… thoughts. These backups are all well and good if I accidentally delete a file, or a database gets corrupted, or something, but there are two glaring issues:

Firstly, I’m backing up my Hetzner server to Hetzner cloud storage. If something happens to Hetzner — or my Hetzner account — then all my eggs go down with that basket. Obviously Hetzner are a big organisation and aren’t likely to just vanish overnight, but I’m less confident about my account. Could a false abuse report get it suspended? What if the UK passes even more dumb laws and Hetzner decide it’s easier just to not do business with people here? This is the same sort of concern I have about Google accounts: if you have half of your life in Google Drive and Google Mail, what happens if you comment on a YouTube video, get flagged by an AI moderation process, and your account gets suspended? It’s probably not very likely, but these are things my brain likes to dwell on.

Secondly, the credentials to access the backups sit on each machine that is backed up. If someone malicious gained access to the machine, they’d also have access to delete or tamper with all the backups. It feels a little silly that the same attack could take down both the originals and the backups. There’s no way to avoid that with Hetzner’s S3 implementation, as far as I can tell.

Exploring options

I toyed with the idea of making local copies of the backups, but the only way to avoid the same problems would be to keep them offline and do a manual copy every now and then. I didn’t really want to do that, and was concerned that if I did a monthly offline backup then I stood to lose up to a month of data in the worst case.

I then looked around at other S3 providers. Amazon’s glacier offering is tempting due to its very low storage costs, but you pay for that if you ever want to restore anything. There are also lots of weird pricing edge cases around moving data between storage classes, minimum file sizes, and so on. A much better option is Backblaze’s B2 product. Their pricing is much more straight-forward, and they have an interesting feature that’s particularly useful in this case: lifecycle rules. Coupled with the ability to create API keys that don’t have access to delete files (just “hide” them), this allows for what’s effectively an append-only store.

This works more-or-less out of the box with Restic. Joseph Price has a guide that goes into the setup in a bit more depth. Basically, whenever Restic would delete a file (e.g. during a “forget” or “prune” operation), it instead gets hidden and is only deleted when the B2 lifecycle rules decide it should be. I’ve kept the existing Hetzner S3 backups for now, and just added an extra step to the end of my script: a simple restic copy and a restic forget. B2 actually works out cheaper than the Hetzner storage, as they don’t bill you for a minimum of 1TB storage; my current usage is around $3/month. Not a bad price for some extra peace of mind!

Further Adventures in Music Organisation

2025-09-21T00:00:00Z

I wrote before about how I’d dropped Spotify in favour of locally stored music, but things have advanced a bit since. I had a few issues: Tauon would occasionally manage to lose its database and along with it all my carefully constructed playlists and song ratings¹, and the experience on my phone was not very fun.

I had to manually sync the music by plugging my phone in to the computer, and sometimes it just refused to mount the right partition. I don’t think there’s really a good way to debug an Apple phone not behaving properly when connected to a Linux desktop. Then I started wanting more than one playlist synced², and trying to find a way to make that work just broke me.

I spent a while looking at different ways of hosting the music centrally. Plexamp gets lots of good reviews, and I’ve used Plex a fair bit. I set about spinning up a Plex server, and just could not get it working. The server ran fine, served the web interface, but would neither associate with my account nor run standalone. The docs were contradictory and there was very little useful logging. After a lot of frustration, I stumbled across mentions that Plex block running on Hetzner. I assume that’s the cause of my issues, although I have no way to know for sure. I use Hetzner for all my servers and other hosted services, but Plex have decided I can’t run the self-hosted software that I have a lifetime subscription for there. What the actual fuck?

I could have probably worked around the arbitrary restriction, but I didn’t want to throw more time down the drain. Instead, I set up Navidrome, an open source music server. It supports the Subsonic protocol, which means you can use a whole slew of different clients with it (or even write your own). It also means there’s a nice way to get data in and out of it programmatically, which I recall being a bit of a fight with Plex.

Syncing and organising

All my music lived on my desktop, but now I wanted it on my server. At first I just used rsync to copy everything up. I’d maintain a local “master” copy, and periodically shove the changes to the server³. That quickly got old, so I set up Syncthing to keep the two folders in sync. That worked… for a while.

Concurrently, I was looking at improving the organisation of my music. It was mostly organised by some Go programs I’d thrown together to automate the importing, with no real validation of metadata or anything else. Some albums got split up into multiple folders because the tracks had different artists (and didn’t have an album artist set); some artists ended up with multiple folders with slight spelling or case variations. It was upsetting.

I’d used MusicBrainz Picard before to fix some issues, but I didn’t really like the UI, especially when trying to do bulk actions. The main alternative is beets, which describes itself as “the music geek’s media organiser”, and is entirely command line. I was intrigued.

I started playing around with beets, and quickly noticed a problem. Every time I changed a metadata tag in a music file, Syncthing had to upload the entire file. I was frequently changing tags across the whole library as I got beets set up how I wanted, and Syncthing was handling it by uploading gigabytes of files for every minor change. I was already a bit unhappy with having the content duplicated in two places, so now I was using a command line organiser I figured I could just get rid of my local copy and move everything to the server.

I set up a Docker container for beets, and then wrote some incredibly hacky shell scripts so I could run beet locally on my desktop and it would SSH to the server over Tailscale and exec into the container, passing the arguments along. Then I did one final sync of the music library, got rid of Syncthing, double checked I had a backup and deleted all of my local music.

Bears, Beets, Battlestar Galactica

Beets is amazing. It has a vast array of plugins that can do almost anything you could want with a music library, and the command line workflow works really well for me. It’s very well documented, and all the individual parts are pleasingly simple and easy to understand.

Here’s what it looks like when importing some new music:

Beets importing an album

If it doesn’t get a perfect match then it shows the closest matches, and summarises what’s different about them (missing tracks, different names, etc), and lets you decide what to do. Aside from the metadata matching, it’s doing a lot of things under the hood that aren’t necessarily apparent. It:

Looks up the genre from Last.fm
Analyses all the tracks and writes ReplayGain metadata to them
Fetches album art
Checks all the files to make sure they’re actually playable
Scrubs any existing metadata tags

It also maintains its own database, and you can query against it. The query language is both simple and quite powerful, like the rest of beets. As an example:

$ beet ls artist:"Linkin Park" year:2025 length:2:00..2:30 
Linkin Park - From Zero - Casualty

Almost all the other commands also let you use the query syntax, which makes the whole tool really powerful. Want to delete all country tracks that you added last month? No problem. Redownload all the album art for a certain band? Easy. You can even do smart playlists using the filters.

Actually playing music

With all this organisation, I’ve not actually mentioned one tiny detail: how I actually play music now. Navidrome has a web UI, which is perfectly usable, but I don’t really want my web browser involved as it makes balancing sound levels tricky, and getting media keys working is a pain. Thankfully there are loads of Subsonic clients. I’ve tried several, but eventually settled on Feishin on the desktop. It’s very pretty:

Feishin’s ’now playing’ screen

What attracted me to it, though, was its built-in support for Navidrome’s smart playlists. These aren’t even properly exposed in Navidrome’s web UI yet, but Feishin has a visual editor that lets you create and edit them. I ended up with an identical system to the playlists I had in Tauon: a “blacklist” playlist which are tracks I never want to play, a “favourites” playlist, and then an “everything” playlist which is the entire catalogue minus the blacklist.

On iOS I’ve settled on Arpeggi. It’s not actually on the App Store yet, but available via TestFlight. It’s one of those really nicely polished apps that are obviously a labour of love, not just out to do the minimum possible to get your money. It can cache songs offline, and automatically download entire playlists, and supports all of the standard Subsonic features like rating, reporting plays back to the server, and so on.

One unexpected benefit of using a central server is that it handles reporting plays to Last.fm and ListenBrainz instead of the clients. I don’t think I’ve ever bothered to configure my mobile clients to do that before, and now it just works automagically. I’m relying on those services more for recommendations and discovery, as that’s something you lose out on when self-hosting.

Making bad decisions about bitrates

With all the moving, copying, and organising, I started thinking about how large the collection was. The songs were all in different formats, depending on when and where I’d picked them up, and I couldn’t tell the difference between them. I did a test and transcoded an MP3 file down to 128kbps, and still couldn’t tell the difference. So armed with that sample size of 1, I transcoded the entire library and saved so much space.

I don’t remember which track I did that first test with, but it must have been a very unlucky pick. I quickly started to notice the distortions caused by the low bitrate. It was particularly bad in any song with a lot of treble, and started to really annoy me. I started a painful process of reimporting things in their original format. Beets came in clutch again, both with the import process (if you import a duplicate album, it asks if you want to replace the original, and shows the format and bitrate of them for comparison), and keeping track of what was left to fix (beet ls bitrate:..128000).

Having started paying more attention to the sound quality, I think I’ve been nibbled on by the audiophile bug. I’ve been trying to get new music in FLAC format where possible. I’m pretty sure I can’t tell the difference between a decent bitrate MP3 and a FLAC, but maybe if I got a better DAC and some nice headphones…? Someone please hide my credit card!

As for the library taking up a lot of space, I now realise it’s a price worth paying. I might need to swap out the server to one with more storage at some point in the future, but it’s generally worth upgrading every few years with rented dedicated servers anyway, as you often get more for the same amount of money. Next upgrade I’ll just make sure there’s an appropriately-sized disk instead of focusing entirely on RAM and CPU.

Writing more code

Naturally, this whole process spawned several side projects. When browsing albums in Navidrome, I was a bit upset that the album art wasn’t all a consistent size. I thought about scripting something to crop them consistently, but then I had a better idea, and jewelcase was born. It takes the album art, crops it down to a consistent size, and then renders it inside a jewel case. It applies some slight effects, like adjusting the colours, rounding the corners, and tweaking the edges so it looks a bit more real. I don’t know why⁴, but every time I see the effect it gives me a little spark of joy.

The other project is BASS, a tool that uses the Subsonic API to grab information about my music catalogue, and then generates a “Daily Mix” playlist. It uses a system of weights to select tracks semi-randomly, biasing towards favourite tracks, those that haven’t been played much, and a few other criteria. This gives me a nice balance between having my favourites on repeat, and exploring the full library at random.

All the weights in BASS are customisable, so I can tweak it to my heart’s desire, and anyone else can also run it and configure it entirely differently to me if they want to. I can’t imagine I would’ve been able to do that if I were using Plex!

I was running a version from git as the stable release had fun dependency issues on Arch, so it’s possible this wouldn’t be an issue in normal use. I also started backing up the database, but it’s still annoying to have to restore it. ↩︎
A “favourites” playlist for me, and a more “family friendly” playlist for when I’m playing music out loud that has a bit less screaming/swearing/etc. ↩︎
One of the reasons for starting this was being annoyed by the periodic sync to my phone, obviously it makes perfect sense to introduce a new, different periodic sync. ↩︎
Nostalgia? A little bit of OCD? Both? ↩︎

10 Weeks with an Apple Watch 10

2025-09-09T00:00:00Z

My watch. Yes, I am available for wrist modelling opportunities.

Around ten weeks ago¹ I picked up an Apple Watch 10, and have been wearing it almost constantly since. It’s not my first Apple Watch — I had a Series 5 for a bit back in 2020 — but it’s the first time I’ve actually stuck with it. Ten weeks seems like an apt time to reflect on it.

Firstly, why did I even bother? Well, for a couple of years I’d been wearing a Xiaomi Smart Band 7, mainly to monitor my sleep stats and set alarms that won’t wake up everyone else nearby. Its battery life was fantastic — with notifications and other things turned off, I got about a month of use between charges — but actually using it felt like trying to order food via the medium of interpretive dance.

My biggest gripe was the screen lock. If I didn’t have the screen locked then I’d periodically trigger it during the night when I moved around and it came in contact with my chest or leg. With the lock enabled you had to deliberately swipe up from bottom to top to enable interaction, but it didn’t work reliably. When I wanted to adjust an alarm, I’d be stood swiping repeatedly trying to get it to respond. When you finally get it unlocked, the whole interface is just fiddly.

The other issue was the data quality. There were some nights when I’d been woken up, sometimes even getting up and moving around, and it just didn’t show it in the data. If it can’t even get whether I’m asleep right, can I trust anything else it says?

I spent a while researching the best devices for sleep tracking. The Oura ring came highly recommended, but it was expensive and required a subscription to do anything useful. No thanks! The Apple Watch was consistently rated pretty well, and I reasoned I could pick up a refurbished older unit. I’ve been using an iPhone as my daily driver for a while, so it’d fit right into my begrudged walled garden.

The Series 10 has a significant advantage, though: it charges much quicker than all the previous generations. On a 30-minute charge, the Series 10 can go from 0 to 60%; the 9 can only make it to 40%, and my old 5 a measly 30%. Shorter charge times means I’m far less likely to leave it on charge and wander off without it. In some ways the daily charging is more convenient than monthly: the wireless charger sits on my desk, and I plop the watch on it for a little while in the evening; I don’t need to dig out the weird pogo-pin connector that has vanished sometime in the last four weeks, then carefully arrange it so it stays attached.

How a watch maybe saved my life

One of the big features of the Apple Watch, like many other wearable devices, is health and fitness tracking. I didn’t think much about this, beyond the sleep data I wanted, at first. I’ve never had a particularly good relationship with exercise², but I do like some good statistics. I started going for walks more often to get more data and see the graphs of VO2 max and HR recovery gradually inch up. That wasn’t the most profound effect on my health, though…

The recent versions of the Apple Watch have a feature that monitors for sleep apnea, a disorder where you don’t breathe properly during your sleep. I knew I wasn’t sleeping great — that’s why I was paying attention to sleep tracking data — but was still a bit surprised to get a notification from Apple Health after wearing the watch for 30 days. It gives you a graph to print and take to your doctor. So I diligently booked an appointment and a few weeks later went to see my GP.

The appointment went about as you’d expect: talking about referral to a sleep centre for a study, and so on. Towards the end, the doctor took my blood pressure (sleep apnea can be caused by, and can cause high blood pressure, in a lovely little vicious cycle). I don’t think either of us expected anything; it was just one of those standard checks for a related problem. After taking the reading, the doctor looked at me and said, “I can’t let you leave with a BP like this”. Yikes!

Blood pressure readings are split into stages: normal is under 120 mmHg³ over 80 mmHg⁴, stage 1 is up to 140/90, stage 2 is up to 180/120, and above is simply called “crisis”. Guess where I was? Also, fun fact: depending on how exactly you count and attribute things, hypertension comes out as the single largest cause of death in humans. It doesn’t kill you outright, but contributes to strokes, coronary artery disease, heart failure, and lots of other lovely things you don’t want on your CV.

After doing a few more readings, it settled down to just under the “crisis” stage and into the “holy crap, start treatment immediately” stage instead. I won’t labour on much more about this, but things are definitely moving in the right direction now⁵.

While the Apple Watch didn’t literally save my life, it triggered the chain of events that led to this diagnosis and treatment. Who knows what would have happened had it remained undetected? Probably nothing good. Also, go check your blood pressure! It’s simple to do and simple to treat if there is an issue, but so many people are walking around with hypertension and not even realising.

Building gates in the walled garden

Even though the watch is arguably a life-saver, not everything is rosy. It’s an Apple product, so you’re firmly locked in a walled garden, jealously guarded by people wearing black turtlenecks. Fortunately, there are a few ways to make it less painful.

All the health and fitness data is stored in Apple Health. You can export data as a big messy file, but it’s a very manual process to do so and the data format is gnarly. Luckily, there’s an app for that! Health Auto Export can, well, automatically export health data. It does what it says on the tin. It can send the data to Home Assistant, over MQTT, or dump it in some cloud file services, but I just have it post it all to a REST endpoint on a service I wrote. Then I dump it all in a database and can do whatever I want with it!⁶

Another tool that’s more useful on the watch itself is Apple Shortcuts. This is their no-code “if-this-then-that”-type thing. You can make automations or shortcuts that run a number of tasks. I have a whole slew of them I access via a complication⁷ on my watch face: one which prompts for input and adds an item to my to-do list (swiping to write letters is surprisingly not horrible), one which lets me select from a bunch of pre-written ones (“charge kindle”, “take laundry out in 1 hour”, type things), one to log my weight into Apple Health, one which can open and close the blinds in my room, and so on. It’s a surprisingly robust and easy-to-use system and offers just enough freedom that I’m not constantly grating on the edge of the walled garden.

Shortcuts being able to initiate arbitrary web requests is the real killer feature for me. Anything I can’t do on the watch itself, I can just farm off to a web server and connect it up with a shortcut. No need to learn Swift or pay Apple for the privilege of being a developer! For a lot of things, like controlling the blinds or adding to-do items, I already had a HTTP endpoint available and exposed over Tailscale⁸. Adding it to the watch was just a case of entering the right things in the Shortcuts app.

Daily nitty-gritty

There are lots of other little bits and pieces that come up when using the watch daily. I don’t think I can bundle them up into a pleasing narrative arc, so instead please enjoy some disjointed paragraphs of observations.

The Apple Watch has a lot of nagging abilities. It can notify you about your fitness “rings”, prompt you to stand up every hour, count how many seconds you wash your hands for, etc. I think I’d dislike these just on general principle, but the way it does them is so condescending it’s painful. I think there’s probably a cultural divide issue here, but there is no way in British English to say “Great job! You washed your hands for 30 seconds!” without it sounding like you’re being amazingly sarcastic or like you’re talking to a young child. So I turned all of that nonsense off. It’s meant to be a tool not a wannabe life coach.

You can access Maps directly on the watch and even do navigation. It works really well. The navigation mode has some nice haptic feedback: it does a short pulse as you’re approaching a turn, and then a long pulse at the actual turn. I like it a lot more than having to dig out my phone or have the directions read out. You get one pulse, glance down and see where you need to go, then it reminds you a little later when it’s time to do it. It’s a delightful user experience.

Watchfaces aren’t quite so delightful. There’s a limited number of built-in ones, and some are “exclusive” to the Ultra Series, and you can’t use them on a peasant watch like a Series 10. Annoyingly, there’s not one that does exactly what I want: a plain analogue clock with an inset date and four complication slots around the outside. Instead, I have to use one of the slots to show the date. There are third-party watchfaces, but they have issues. Firstly, there’s no actual API for making watchfaces⁹, so what they do is bodge it horribly by using a photo background that has fake widgets on it. On top of that they’re almost universally subscription-based. Again, no thanks¹⁰.

The issue I had with the Smart Band triggering when I was sleeping is solved trivially on an Apple Watch, by virtue of it having a physical button in the crown. When you put it in sleep mode, you have to double-press the crown to unlock it before it’ll do anything else. It hasn’t misfired once while I’ve been using it.

Sleep data; spot when I swapped devices!

Finally, a special mention for the gesture controls. If you raise the watch it reliably wakes up (switching from a low refresh rate, dimmed screen to an active, brighter one); you can then double-tap your index finger and thumb together and it will scroll down or page through whatever you’re looking at. The killer feature for this is navigating recipes: you can advance to the next step in a recipe while your hands are covered in flour. It’s also handy for reading notifications: when one pops up, you can double-tap to expand it, then, when it gets to the bottom, it’ll outline the default button (often “Dismiss”) and you can double-tap again to click it.

The verdict

I normally don’t like writing an actual labelled conclusion, but it feels like one is needed here! Overall, I’m happy with the watch. The daily charging doesn’t bother me, the data gathered seems reliable, the health monitoring has obviously paid dividends already, and the walled garden isn’t too chafing. It’s a straight upgrade over my old Smart Band, and I think it was worth the cost.

The original reason for getting the watch was better sleep tracking, though, so how well did it do? I’m much happier with the data: it seems to more accurately represent when I was awake in the night, and overall the sleep phases just seem to make more sense. You can see in the graph that the old data switched frequently between phases, and they didn’t quite line up for some reason; towards the right when the Apple Watch is supplying the data instead there’s a much more consistent pattern of sleep phases that repeat over the course of the night.

I’m not going to advocate that you go out and buy one, though. I know my requirements and usage aren’t typical, and I’ve also not got experience with any recent Android Wear alternatives or the new version of the Pebble watch that’s coming soon. You should definitely get your blood pressure checked, though!

OK, it’s more like 14 now, it’s taken a while for this post to make its way from my brain into text. ↩︎
Exercise for the sake of exercising just seems so overwhelmingly tedious and boring to me. And other types of exercise generally require social interaction, coordinating with people, and so on. ↩︎
Who decided to use “millimetres of mercury displaced” as a unit? You can’t just put random chemical symbols in units! That’s not how this works! ↩︎
Blood pressure readings have two parts: systolic (the pressure when the heart is beating) and diastolic (the pressure between those beats). They’re generally presented with the systolic reading on top and the diastolic reading below, and read as “X over Y”. Now you know what some of the random numbers they shout in medical shows mean! Yay learning! ↩︎
No thanks to how much salt is in everything. I’m pretty sure I’ve had at least twice the recommended daily amount of salt in a single serving before. Don’t even get me started on the things that are “low salt” but are still full of sodium from other sources. I don’t have a problem with ionic compounds, I have a problem with sodium! ↩︎
This mainly looks like drawing graphs that are slightly different to the graphs in the Apple Health graphs, for reasons I’m not sure I can explain. Making graphs is fun, OK? ↩︎
Complications are basically just home screen widgets, but with a fancy name because they’re on a watch. ↩︎
Tailscale actually causes me some problems here: everything works fine when the watch is connected to my phone, as the phone handles the Tailscale part, but if I’m not carrying my phone the watch will try to connect over WiFi directly and doesn’t understand anything about Tailscale. It happens infrequently enough that I’ll just live with it; it’s not much worse than having no signal on a phone. ↩︎
Yay walled gardens… ↩︎
I don’t object to subscribing to things in general, but it has to be something that’s worth the ongoing cost and offers something in return for the subscription. A watchface doesn’t need enough ongoing maintenance to justify subscribing to it, it’s just a cash grab. ↩︎
