Vmail is cool. It’s vole.wtf’s (of ARCC etc. fame) community
newsletter, and it’s as batshit crazy as you’d expect if you were to get the kinds of people who enjoy that site and asked them all to chip in on a newsletter.
Totes bonkers.
But email’s not how I like to consume this kind of media. So obviously, I scraped it.
I’m not a monster: I want Vmail’s stats to be accurate. So I signed up with an unmonitored OpenTrashMail account as well. I just don’t read it (except for the confirmation link
email). It actually took me a few attempts because there seems to be some kind of arbitrary maximum length validation on the signup form. But I got there in the end.
Recipe
Want to subscribe to Vmail using your own copy of FreshRSS? Here’s the settings you’re looking for –
Type of feed source:HTML + XPath (Web scraping)
XPath for finding news items://table/tbody/tr
It’s just a table with each row being a newsletter; simple!
XPath for item title:descendant::a
XPath for item content:.
XPath for item link (URL):descendant::a/@href
XPath for item date:descendant::td[1]
Custom date/time format:d M *y
The dates are in a format that’s like 01 May ’24 – two-digit days with leading zeros, three-letter months, and a two-digit year preceded by a curly quote, separated by spaces. That
curl quote screws up PHP’s date parser, so we have to give it a hint.
XPath for unique item ID:descendant::th
Optional, but each issue’s got its own unique ID already anyway; we might as well use it!
Article CSS selector on original website:#vmail
Optional, but recommended: this option lets you read the entire content of each newsletter without leaving FreshRSS.
So yeah, FreshRSS continues to be amazing. And lately it’s helped me keep on top of the amazing/crazy of vole.wtf too.
I’m not a tea-drinker1. But while making a cuppa for Ruth
this morning, a thought occurred to me and I can’t for a moment believe that I’m the first person to think of it:
Modern digital pressure cookers have a lot of different settings and modes, but ‘tea’ is somehow absent?
It’s been stressed how important it is that the water used to brew the tea is 100℃, or close to it possible. That’s the boiling point of water at sea level, so you can’t really boil
your kettle hotter than that or else the water runs away to pursue a new life as a cloud.
That temperature is needed to extract the flavours, apparently3.
And that’s why you can’t get a good cup of tea at high altitudes, I’m told: by the time you’re 3000 metres above sea level, water boils at around 90℃ and most British people wilt at
their inability to make a decent cuppa4.
It’s a question of pressure, right? Increase the pressure, and you increase the boiling point, allowing water to reach a higher temperature before it stops being a liquid and starts
being a gas. Sooo… let’s invent something!
I’m thinking a container about the size of a medium-sized Thermos flask or a large keep-cup – you need thick walls to hold pressure, obviously – with a safety valve and a heating
element, like a tiny version of a modern pressure cooker. The top half acts as the lid, and contains a compartment into which you put your teabag or loose leaves (optionally in an
infuser). After being configured from the front panel, the water gets heated to a specified temperature – which can be above the ambient boiling point of water owing to the
pressurisation – at which point the tea is released from the upper half. The temperature is maintained for a specified amount of time and then the user is notified so they can release
the pressure, open the top, lift out the inner cup, remove the teabag, and enjoy their beverage.
This isn’t just about filling the niche market of “dissatisfied high-altitude tea drinkers”. Such a device would also be suitable for other folks who want a controlled tea experience.
You could have it run on a timer and make you tea at a particular time, like a teasmade. You can set the temperature lower for a
controlled brew of e.g. green tea at 70℃. But there’s one other question that a device like this might have the capacity to answer:
What is the ideal temperature for making black tea?
We’re told that it’s 100℃, but that’s probably an assumption based on the fact that that’s as hot as your kettle can get water to go, on account of physics. But if tea is bad
when it’s brewed at 90℃ and good when it’s brewed at 100℃… maybe it’s even better when it’s brewed at 110℃!
A modern pressure cooker can easily maintain a liquid water temperature of 120℃, enabling excellent extraction of flavour into water (this is why a pressure cooker makes such
excellent stock).
It’s possible that the perfect cup of tea hasn’t been invented yet, owing to limitations in the boiling point of water.
I’m not the person to answer this question, because, as I said: I’m not a tea drinker. But surely somebody’s tried this5? It shouldn’t be too hard to retrofit a pressure cooker lid with a
sealed compartment that releases, even if it’s just on a timer, to deposit some tea into some superheated water?
Because maybe, just maybe, superheated water makes better tea. And if so, there’s a possible market for my proposed device.

1 I probably ought to be careful confessing to that or they’ll strip my British
citizenship.
3 Again, please not that I’m not a tea-drinker so I’m not really qualified to comment on
the flavour of tea at all, let alone tea that’s been brewed at too-low a temperature.
4 Some high-altitude tea drinkers swear by switching from black tea to green tea, white
tea, or oolong, which apparently release their aromatics at lower temperatures. But it feels like science, not compromise, ought to be the solution to this problem.
5 I can’t find the person who’s already tried this, if they exist, but maybe they’re out
there somewhere?
Part of the joy of the collaborative Internet is that people can share their passion. Today’s example comes from this YouTuber who’s made an hour long video demonstrating and
ranking the 35 elevators in the first five games in the Myst series.
Starting with a discussion of what defines an elevator, the video goes on to show off some of the worst of the lifts in the series of games (mostly those that are uninspired,
pointless, or which have confusing interfaces) before moving on to the well-liked majority.
I only ever played the first two Myst games (and certainly haven’t played the first since, what, the mid-1990s?) and I don’t think I finished either. But that didn’t stop me
watching the entirety of this video and revelling in the sheer level of dedication and focus it’ll have taken on the part of the creator. When I made my
(mere 15-minute!) video describing my favourite video game Easter Egg I spent tens of hours over the prior weeks researching the quirk and its background, configuring a copy of the
(elderly) game so that it’d play and record in the way I wanted, and of course playing through the game far enough to be able to fully demonstrate the Easter Egg. Dustin’s
video, which doubtless involved replaying (possibly multiple times) five different games released over a 12-year window is mindblowing by comparison.
I don’t really care about the Myst series. I care even less about its elevators. But I really enjoyed this video, if only for its creator’s enthusiasm.
Humans invented Wikipedia, which made accessing information highly-convenient, at the risk of questions about its authenticity1.
Then humans invented GPTs, which made accessing information even more-convenient2
at the expense of introducing hallucinations that can be even harder to verify and check.
Is humanity’s long-term plan to invent something that spews complete nonsense that’s simultaneously impossible to conclusively deny?3

sources they omitted to include. I love Wikipedia, but I can’t deny its weaknesses.
2 Sure, ChatGPT and friends aren’t always more-convenient. But if you need to

3 Actually, now I think about it, I’m confident that I can name some politicians who are
ahead of the machines, for now.
Sometimes I’ve seen signs on dual carriageways and motorways that seem to specify a speed limit that’s the same as the national speed
limit (i.e. 60 or 70 mph for most vehicles, depending on the type of road), which seem a bit… pointless? Today I learned why they’re there, and figured I’d share with you!
The first time I saw this sign, on the A1 near Edinburgh, I wondered why it wasn’t just a national speed limit/derestriction sign. Now I know.
To get there, we need a history lesson.
As early as the 1930s, it was becoming clear that Britain might one day need a network of high-speed, motor-vehicle-only roads: motorways. The first experimental part of this
network would be the Preston By-pass1.
Construction halted on several occasions owing to heavy rain, and only six weeks after opening the road needed to be closed for resurfacing after the discovery that water had
penetrated the material.
Construction wouldn’t actually begin until the 1950s, and it wasn’t just the Second World War that got in the way: there was a legislative challenge too.
When the Preston By-pass was first conceived, there was no legal recognition for roads that restricted the types of traffic that were permitted to drive on them. If a public highway
were built, it would have to allow pedestrians, cyclists, and equestrians, which would doubtless undermine the point of the exercise! Before it could be built, the government needed to
pass the Special Roads Act 1949, which enabled the designation of public roads as “special roads”, to which
entry could be limited to certain classes of vehicles2.
The original motorways had to spell out the regulations at their junctions.
If you don’t check your sources carefully when you research the history of special roads, you might be taken in by articles that state that special roads are “now known as motorways”,
which isn’t quite true. All motorways are special roads, by definition, but not all special roads are motorways.
There’s maybe a dozen or more non-motorway special roads, based on research by Pathetic Motorways (whose site was
amazingly informative on this entire subject). They tend to be used in places where something is like a motorway, but can’t quite be a motorway. In Manchester, a
couple of the A57(M)’s sliproads have pedestrian crossings and so have to be designated special roads rather than motorways, for example3.
“…is hereby varied by adding Class IX of the Classes of Traffic set out in Schedule 4 to the Highways Act 1980 as a class of traffic permitted to use those lengths of the special
roads described in the Schedule to this Scheme and which…” /snoring sounds intensify/
Now we know what special roads are, that we might find them all over the place, and that they can superficially look like motorways, let’s talk about speed limits.
The Road Traffic Act 1934 introduced the concept of a 30mph “national speed limit” in built-up areas,
which is still in force today. But outside of urban areas there was no speed limit. Perhaps there didn’t need to be, while cars were still relatively slow, but automobiles
became increasingly powerful. The fastest speed ever legally achieved on a British motorway came in 1964 during a test by AC Cars, when driver Jack Sears reached 185mph.
The “M48” Severn Bridge is another example of a special road that appears to be part of a motorway. The cycle lane and footpath (which is not separated from the main carriageway by
more than a fence) is the giveaway that it’s not truly a “motorway” but a general-case special road.
In the late 1960s an experiment was run in setting a speed limit on motorways of 70mph. Then the experiment was extended. Then the regulation was made permanent.
There’ve been changes since then, e.g. to prohibit HGVs from going faster than 60mph, but fundamentally this is where Britain’s
national speed limit on motorways comes from.
I assume that it relates to the devolution of transport policy or to the separation of legislation that it replaces, but separate-but-fundamentally-identical acts were passed for
Scotland and Northern Ireland.
You’ve probably spotted the quirk already. When “special roads” were created, they didn’t have a speed limit. Some “special roads” were categorised as “motorways”, and “motorways” later
had a speed limit imposed. But there are still a few non-motorway “special roads”!
Putting a national speed limit sign on a special road would be meaningless, because these roads have no centrally-legislated speed limit. So they need a speed limit sign, even
if that sign, confusingly, might specify a speed limit that matches what you’d have expected on such a road4.
That’s the (usual) reason why you sometimes see these surprising signs.
As to why this kind of road are much more-common in Scotland and Wales than they are anywhere else in the UK: that’s a much deeper-dive
that I’ll leave as an exercise for the reader.
Footnotes
1 The Preston By-pass lives on, broadly speaking, as the M6 junctions 29 through 32.
2 There’s little to stop a local authority using the powers of the Special Roads Act and
its successors to declare a special road accessible to some strange and exotic permutation of vehicle classes if they really wanted: e.g. a road could be designated for cyclists and
horses but forbidden to motor vehicles and pedestrians, for example! (I’m moderately confident this has never happened.)
4 An interesting side-effect of these roads might be that speed restrictions based on the
class of your vehicle and the type of road, e.g. 60mph for lorries on motorways, might not be enforceable on special roads. If you wanna try driving your lorry at
70mph on a motorway-like special road with “70” signs, though, you should do your own research first; don’t rely on some idiot from the Internet. I Am Not A Lawyer etc. etc.
I’ve tried a variety of unusual strategies to combat email spam over the years.
Here are some of them (each rated in terms the geekiness of its implementation and its efficacy), in case you’d like to try any yourself. They’re all still in use in some form or
another:
Spam filters
Geekiness: 1/10
Efficacy: 5/10
Your email provider or your email software probably provides some spam filters, and they’re probably pretty good. I use Proton‘s
and, when I’m at my desk, Thunderbird‘s. Double-bagging your spam filter only slightly reduces the amount of spam
that gets through, but increases your false-positive rate and some non-spam gets mis-filed.
A particular problem is people who email me for help after changing their name on FreeDeedPoll.org.uk, probably
because they’re not only “new” unsolicited contacts to me but because by definition many of them have strange and unusual names (which is why they’re emailing me for help in the first
place).
Frankly, spam filters are probably enough for many people. Spam filtering is in general much better today than it was a decade or two ago. But skim the other suggestions in
case they’re of interest to you.
Unique email addresses
Geekiness: 3/10
Efficacy: 8/10
If you give a different email address to every service you deal with, then if one of them misuses it (starts spamming you, sells your data, gets hacked, whatever), you can just block
that one address. All the addresses come to the same inbox, for your convenience. Using a catch-all means that you can come up with addresses on-the-fly: you can even fill a paper
form with a unique email address associated with the company whose form it is.
On many email providers, including the ever-popular GMail, you can do this using plus-sign notation. But if you want to take your unique addresses to the next level and you have your own domain name (which you should), then you can simply redirect all email addresses on that domain to the same inbox. If Bob’s Building Supplies
wants your email address, give them bobs@yourname.com, which works even if Bob’s website erroneously doesn’t accept email addresses with plus signs in them.
This method actually works for catching people misusing your details. On one occasion, I helped a band identify that their mailing list had been hacked. On another, I caught a
dodgy entrepreneur who used the email address I gave to one of his businesses without my consent to send marketing information of a different one of his businesses. As a bonus, you can
set up your filtering/tagging/whatever based on the incoming address, rather than the sender, for the most accurate finding, prioritisation, and blocking.
Also, it makes it easy to have multiple accounts with any of those services that try to use the uniqueness of email addresses to prevent you from doing so. That’s great if, like me, you
want to be in each of three different Facebook groups but don’t want to give Facebook any information (not even that you exist at the intersection of those groups).
Signed unique email addresses
Geekiness: 10/10
Efficacy: 2/10
Unique email addresses introduce two new issues: (1) if an attacker discovers that your Dreamwidth account has the email address dreamwidth@yourname.com, they can
probably guess your LinkedIn email, and (2) attackers will shotgun “likely” addresses at your domain anyway, e.g. admin@yourname.com,
management@yourname.com, etc., which can mean that when something gets through you get a dozen copies of it before your spam filter sits up and takes notice.
What if you could assign unique email addresses to companies but append a signature to each that verified that it was legitimate? I came up with a way to do this and
implemented it as a spam filter, and made a mobile-friendly webapp to help generate the necessary signatures. Here’s what it looked like:
The domain directs all emails at that domain to the same inbox.
If the email address is on a pre-established list of valid addresses, that’s fine.
Otherwise, the email address must match the form of:
A string (the company name), followed by
A hyphen, followed by
A hash generated using the mechanism described below, then
The @-sign and domain name as usual
The hashing algorithm is as follows: concatenate a secret password that only you know with a colon then the “company name” string, run it through SHA1, and truncate to the first eight characters. So if my password were swordfish1 and I were generating a password for Facebook, I’d go:
Therefore, the email address is facebook-977046ce@myname.com
If any character of that email address is modified, it becomes invalid, preventing an attacker from deriving your other email addresses from a single point (and making it
hard to derive them given multiple points)
I implemented the code, but it soon became apparent that this was overkill and I was targeting the wrong behaviours. It was a fun exercise, but ultimately pointless. This is the one
method on this page that I don’t still use.
Honeypots
Geekiness: 8/10
Efficacy: ?/10
A honeypot is a “trap” email address. Anybody who emails it get aggressively marked as a spammer to help ensure that any other messages they send – even to valid email
addresses – also get marked as spam.
I litter honeypots all over the place (you might find hidden email addresses on my web pages, along with text telling humans not to use them), but my biggest source of
honeypots is formerly-valid unique addresses, or “guessed” catch-all addresses, which already attract spam or are otherwise compromised!
I couldn’t tell you how effective it is without looking at my spam filter’s logs, and since the most-effective of my filters is now outsourced to Proton, I don’t have easy access to
that. But it certainly feels very satisfying on the occasions that I get to add a new address to the honeypot list.
Instant throwaways
Geekiness: 5/10
Efficacy: 6/10
OpenTrashmail is an excellent throwaway email server that you can deploy in seconds with Docker, point some MX records at, and be all set! A throwaway email server gives you an infinite number of unique email addresses, like other solutions described
above, but with the benefit that you never have to see what gets sent to them.
If you offer me a coupon in exchange for my email address, it’s a throwaway email address I’ll give you. I’ll make one up on the spot with one of my (several) trashmail domains at the
end of it, like justgivemethedamncoupon@danstrashmailserver.com. I can just type that email address into OpenTrashmail to see what you sent me, but then I’ll never check it
again so you can spam it to your heart’s content.
As a bonus, OpenTrashmail provides RSS feeds of inboxes, so I can subscribe to any email-based service using my feed reader,
and then unsubscribe just as easily (without even having to tell the owner).
Summary
With the exception of whatever filters your provider or software comes with, most of these options aren’t suitable for regular folks. But you’re only a domain name (assuming you don’t
have one already) away from being able to give unique email addresses to everybody you deal with, and that’s genuinely a game-changer all by itself and well worth considering, in my
opinion.
As our house rennovations/attic conversions come to a close, I found myself up in what
will soon become my en suite, fitting a mirror, towel rail, and other accessories.
Wanting to minimise how much my power tool usage disturbed the rest of the house, I went to close the door separating my new bedroom from my rest of my house, only to find that it
didn’t properly fit its frame and instead jammed part-way-closed.
“Oh,” I said, as the door clearly failed to shut, “Damn.”
Somehow we’d never tested that this door closed properly before we paid the final instalment to the fitters. And while I’m sure they’d have come back to repair the problem if I asked, I
figured that it’d be faster and more-satisfying to fix it for myself.
Homes
As a result of an extension – constructed long before we moved in – the house in Preston in which spent much of my childhood had not just a front and a back door but what we called the
“side door”, which connected the kitchen to the driveway.
Unfortunately the door that was installed as the “side door” was really designed for interior use and it suffered for every winter it faced the biting wet North wind.
The side door isn’t visible in this picture: it’s concealed behind the corner of the house, to the left of the car.
My father’s DIY skills could be rated as somewhere between mediocre and catastrophic, but his desire to not spend money “frivolously”
was strong, and so he never repaired nor replaced the troublesome door. Over the course of each year the wood would invariably absorb more and more water and swell until it became stiff
and hard to open and close.
The solution: every time my grandfather would visit us, each Christmas, my dad would have his dad take down the door, plane an eighth of an inch or so off the bottom, and
re-hang it.
Sometimes, as a child, I’d help him do so.
My paternal grandfather was a practical and hand-on engineer and a reasonable carpenter.
Planes
The first thing to do when repairing a badly-fitting door is work out exactly where it’s sticking. I borrowed a wax crayon from the kids’ art supplies, coloured the edge of the door,
and opened and closed it a few times (as far as possible) to spot where the marks had smudged.
Fortunately my new bedroom door was only sticking along the top edge, so I could get by without unmounting it so long as I could brace it in place. I lugged a heavy fence post rammer
from the garage and used it to brace the door in place, then climbed a stepladder to comfortably reach the top.
I figured I’d only need to remove a few millimetres, so I didn’t mind doing it from atop a stepladder. Hey: here’s a fun thing – when I think about planing a door with my grandfather,
I think in inches; when I think about doing it myself, I think in metric!
Loss
After my paternal grandfather died, there was nobody left who would attend to the side door of our house. Each year, it became a little stiffer, until one day it wouldn’t open at all.
Surely this would be the point at which he’d pry open his wallet and pay for it to be replaced?
I’m not sure there’s a more apt metaphor for my dad’s ability to be stubborn than this photo of him dragging a tyre around Gateshead as a training activity for an Arctic expedition.
Nope. Instead, he inexpertly screwed a skirting board to it and declared that it was now no-longer a door, but a wall.
I suppose from a functionalist perspective he was correct, but it still takes a special level of boldness to simply say “That door? It’s a wall now.”
Sand
Of all the important tasks a carpenter (or in this case, DIY-er) must undertake, hand sanding must surely be the least-satisfying.
You wear your fingers out rubbing a piece of wood smooth, and your only reward is getting to do it again with a slightly finer grade of paper.
But reaching the end of the process, the feel of a freshly-planed, carefully-sanded piece of wood is fantastic. This surface represented chaos, and now it represents
order. Order that you yourself have brought about.
Often, you’ll be the only one to know. When my grandfather would plane and sand the bottom edge of our house’s side door, he’d give it a treatment of oil (in a doomed-to-fail attempt to
keep the moisture out) and then hang it again. Nobody can see its underside once it’s hung, and so his handiwork was invisible to anybody who hadn’t spent the last couple of months
swearing at the stiffness of the door.
Swish, swish. Now I’m glad I sanded.
Even though the top of my door is visible – particularly visible, given its sloping face – nobody sees the result of the sanding because it’s hidden beneath a layer of paint.
A few brush strokes provide the final touch to a spot of DIY… that in provided a framing device for me to share a moment of nostalgia
with you.
The UK’s Conservative government, having realised that their mandate is
worthless, seems to be in a panicked rush to try to get the voters to ignore any of the real issues. Instead, they say, we should be focussed on things like ludicrously-expensive
and ineffective ways to handle asylum seekers and making life as hard as possible for their second-favourite scapegoat: trans and queer people.
By the time John Oliver’s doing a segment about you, perhaps it’s time to realise you’ve fucked up? But our main story tonight is about sex education…
The BBC has not seen the new guidelines but a government source said they included plans to ban any children being taught about gender identity.
If asked, teachers will have to be clear gender ideology is contested.
Needless to say, such guidance is not likely to be well-received by teachers:
Pepe Di’Iasio, headteacher at a school in Rotherham, told Today that he believes pupils are being used “as a political football”.
Teachers “want well informed and evidence-based decisions”, he said, and not “politicised” guidance.
I can only assume that the Tories still have a stack of this genuine 1987 billboard poster (ugh) in stock, and are hoping to save money by reusing them.
People and pupils
This shit isn’t harmless. Regardless of how strongly these kinds of regulations are enforced, they can have a devastating chilling effect in schools.
I speak from experience.
I don’t know if this is the “most-90s” photo I own of myself, but it’s gotta be close. Taken at the afterparty from a school production of South Pacific, so probably at least
a little disproportionately-queer gathering.
Most of my school years were under the shadow of Section 28. Like I predict for the new Conservative proposals, Section 28 superficially didn’t appear to have a major
impact: nobody was ever successfully prosecuted under it, for example. But examining its effects in that way completely overlooks the effect it had on how teachers felt they had to
work.
For example…
In around 1994, I witnessed a teacher turn a blind eye to homophobic bullying of a pupil by their peer, during a sex education class. Simultaneously, the teacher coolly
dismissed the slurs of the bully, saying that we weren’t “talking about that in this class” and that the boy should “save his chatter for the playground”. I didn’t know about
the regulations at the time: only in hindsight could I see that this might have been a result of Section 28. All I got to see at the time was a child who felt that his homophobic
harassment of his classmate had the tacit endorsement of the teachers, so long as it didn’t take place in the classroom.
A gay friend, who will have been present but not involved in the above event, struggled with self-identity and relationships throughout his teenage years, only “coming out” as an adult.
I’m confident that he could have found a happier, healthier life had he felt supported – or at the very least not-unwelcome – at school. I firmly believe that the long-running
third-degree side-effects of Section 28 effectively robbed him of a decade of self-actualisation about his identity.
The long tail of those 1980s rules were felt long-after they were repealed. And for a while, it felt like things were getting better. But increasingly it feels like we’re moving
backwards.
As a country and as a society, we can do better than this.
With general elections coming up later this year, it’ll soon be time to start quizzing your candidates on the issues that matter to you. Even (perhaps especially) if your favourite
isn’t the one who wins, it can be easiest to get a politicians’ ear when they and their teams are canvassing for your vote; so be sure to ask pointed questions about the things you care
about.
I hope that you’ll agree that not telling teachers to conceal from teenagers the diversity of human identity and experience is something worth caring about.
I clearly nerdsniped Terence at least a little when I asked whether a blog necessarily had to be HTML, because he went on to implement a WordPress theme that delivers content entirely in plain text.
theunderground.blog‘s content, with the exception of its homepage, is delivered entirely through an XML Atom feed. Atom feed entries do require <title>s, of course, so that’s not the strongest counterexample!
This blog is available over several media other than the Web. For example, you can read this blog post:
We’ve looked at plain text, which as a format clearly does not have to have a title. Let’s go one step further and implement it. What we’d need is:
A webserver configured to deliver plain text files by preference, e.g. by adding directives like index index.txt; (for Nginx).5
An index page listing posts by date and URL. Most browser won’t render these as “links” so users will have to copy-paste
or re-type them, so let’s keep them short,
Pages for each post at those URLs, presumably without any kind of “title” (just to prove a point), and
An RSS feed: usually I use RSS as shorthand for all feed
types, but this time I really do mean RSS and not e.g. Atom because RSS, strangely, doesn’t require that an <item> has a <title>!
Unlike other sites, I didn’t need to test textplain.blog in Lynx to
know it’d work well. But I did anyway.
In the end I decided it’d benefit from being automated as sort-of a basic flat-file CMS, so I wrote it in PHP. All requests are routed by the webserver to the program, which determines whether they’re a request for the homepage, the RSS feed, or a valid individual post, and responds accordingly.
It annoys me that feed
discovery doesn’t work nicely when using a Link: header, at least not in any reader I tried. But apart from that, it seems pretty solid, despite its limitations. Is this,
perhaps, an argument for my.well-known/feedsproposal?
When was the last time you tested your website in a text-only browser like Lynx (or ELinks, or one of
several others)? Perhaps you
should.
I’m a big fan of CSS Naked Day. I love the idea of JS Naked Day, although I missed it earlier this month (I was busy abroad, plus my aggressive caching,
including in service workers, makes it hard to reliably make sweeping changes for short periods). I’m a big fan of the idea that, for the vast majority of websites, if it isn’t at least
usable without any CSS or JavaScript, it should probably be considered broken.
This year, I thought I’d celebrate the events by testing DanQ.me in the most-limited browser I had to-hand: Lynx. Lynx has zero CSS or JavaScript support, along with limited-to-no support for heading levels, tables, images, etc. That may seem extreme, but it’s a reasonable
analogue for the level of functionality you might routinely expect to see in the toughest environments in which your site is accessed: slow 2G connections from old mobile hardware,
people on the other side of highly-restrictive firewalls or overenthusiastic privacy and security software, and of course users of accessibility technologies.
Here’s what broke (and some other observations):

I see the thinking that Lynx (and in an even more-extreme fashion, ELinks) have with showing “alternate versions” of a page at the top, but it’s not terribly helpful: most of mine are
designed to help robots, not humans!
Four alternates is pretty common for a WordPress site: post feed, comments feed, and two formats of oEmbed.
I wonder if switching from <link rel="alternate"> elements to Link: HTTP headers would
indicate to Lynx that it shouldn’t be putting these URLs in humans’ faces, while still making them accessible to all the
services that expect to find them? Doing so would require some changes to my caching logic, but might result in a cleaner, more human-readable HTML file as a side-effect. Possibly something worth investigating.
Fortunately, I ensure that my <link rel="alternate">s have a title attribute, which is respected by Lynx and ELinks and makes these scroll-past links
slightly less-confusing.
Not all sites title their alternate links. IKEA.com requires you to scroll through 113 anonymous links for their alternate language versions, because Lynx doesn’t understand the
hreflang attribute.
Post list indentation
Posts on the homepage are structured a little like this:
Strictly-speaking, that’s not valid. Heading elements are only permitted within flow elements. I chose to implement it that way because it seemed to be the most semantically-correct way
to describe the literal “list of posts”. But probably my use of <h2> is not the best solution. Let’s see how Lynx handles it:
Lynx “outdents” headings so they stand out, and “indents” lists so they look like lists. This causes a quirky clash where a heading is inside a list.
It’s not intolerable, but it’s a little ugly.
CSS lightboxes add a step to images
I use a zero-JavaScript approach to image lightboxes: you can see it by clicking
on any of the images in this post! It works by creating a (closed) <dialog> at the bottom of the page, for each image. Each <dialog> has a unique
id, and the inline image links to that anchor.
Originally, I used a CSS :target selector to detect when the link had been clicked and show the
<dialog>. I’ve since changed this to a :has(:target) and directed the link to an element within the dialog, because it works better on browsers
without CSS support.
It’s not perfect: in Lynx navigating on an inline image scrolls down to a list of images at the bottom of the page and selects the current one: hitting the link again now
offers to download the image. I wonder if I might be better to use a JavaScript-powered lightbox after all!
gopher: and finger: links work perfectly!
I was pleased to discover that gopher: and finger: links to alternate copies of a post… worked perfectly! That shouldn’t be a surprise – Lynx natively supports
these protocols.
In a fun quirk and unusually for a standard of its age, the Finger specification did not state the character encoding that ought to
be used. I guess the authors just assumed everybody reading it would use ASCII. But both my
WordPress-to-Finger bridge and Lynx instead assume that UTF-8 is acceptable (being a superset of
ASCII, that seems fair!) which means that emoji work (as shown in the screenshot above). That’s
nuts, isn’t it?
You can’t react to anything
Back in November I added the ability to “react” to a post by clicking an emoji, rather than
typing out a full comment. Because I was feeling lazy, the feature was (and remains) experimental, and I didn’t consider it essential functionality, I implemented it mostly in
JavaScript. Without JavaScript, all you can do is see what others have clicked.
The available emoji vary from post to post; I sometimes like to throw a weird/fun one in there, knowing that it’ll invariably be Ruth that
clicks it first.
In a browser with no JavaScript but with functional CSS, the buttons correctly appear disabled.
But with neither technology available, as in Lynx, they look like they should work, but just… don’t. Oops.
Lynx is correct; this is sloppy code. Without CSS support, it even shows the instruction that implies the buttons will work, but they don’t.
If I decide to keep the reaction buttons long-term, I’ll probably reimplement them so that they function using plain-old HTML
and HTTP, using a <form>, and refactor my JavaScript to properly progressively-enhance the buttons for
those that support it. For now, this’ll do.
Comment form honeypot
The comment form on my blog posts works… but there’s a quirk:
At the end of the comments form, an additional <textarea> appears!
That’s an annoyance. It turns out it’s a honeypot added by Akismet: a fake comments field, normally hidden, that tries to trick spam bots into filling
it (and thus giving themselves away): sort-of a “reverse CAPTCHA” where the
robots do something extra, unintentionally, to prove their inhumanity. Lynx doesn’t understand the code that Akismet uses to hide the form, and so it’s visible to humans, which
is suboptimal both because it’s confusing but also because a human who puts details into it is more-likely to be branded a spambot!
I might look into suppressing Akismet adding its honeypot field in the first place, or else consider one of the alternative anti-spam plugins for WordPress. I’ve heard good things about
Antispam Bee; I ought to try it at some point.
Overall, it’s pretty good
On the whole, DanQ.me works reasonably well in browsers without any JavaScript or CSS capability, with only a few optional
features failing to function fully. There’s always room for improvement, of course, and I’ve got a few things now to add to my “one day” to-do list for my little digital garden.
Obviously, this isn’t really about supporting people using text-mode browsers, who probably represent an incredible minority. It’s about making a real commitment to the
semantic web, to accessibility, and to progressive enhancement! That making your site resilient, performant, and accessible also helps make it function in even the
most-uncommon of browsers is just a bonus.
From 1696 until 1851 a “window tax” was imposed in England and Wales1.
Sort-of a precursor to property taxes like council tax today, it used an estimate of the value of a property as an indicator of the wealth of its occupants: counting the number of
windows provided the mechanism for assessment.
The hardest thing about retrospectively graphing the cost of window tax is thinking in “old money”2.
Window tax replaced an earlier hearth tax, following the ascension to the English throne of Mary II and William III of Orange. Hearth tax had come from a similar philosophy: that
you can approximate the wealth of a household by some aspect of their home, in this case the number of stoves and fireplaces they had.
(A particular problem with window tax as enacted is that its “stepping”, which was designed to weigh particularly heavily on the rich with their large houses, was that it similarly
weighed heavily on large multi-tenant buildings, whose landlord would pass on those disproportionate costs to their tenants!)
It’d be temping to blame William and Mary for the window tax, but the reality is more-complex and reflects late renaissance British attitudes to the limits of state authority.
Why a window tax? There’s two ways to answer that:
A window tax – and a hearth tax, for that matter – can be assessed without the necessity of the taxpayer to disclose their income. Income tax, nowadays the most-significant form of
taxation in the UK, was long considered to be too much of an invasion upon personal privacy3.
But compared to a hearth tax, it can be validated from outside the property. Counting people in a property in an era before solid recordkeeping is hard. Counting hearths is
easier… so long as you can get inside the property. Counting windows is easier still and can be done completely from the outside!
If you’re in Britain, finding older buildings with windows bricked-up to save on tax is pretty easy. I took a break from writing this post, walked for three minutes, and found
one.4
There were a few work-related/adjacent activities. But also a table football tournament, among other bits of fun.
One of the things I learned while on this trip was that the Netherlands, too, had a window tax for a time. But there’s an interesting difference.
The Dutch window tax was introduced during the French occupation, under Napoleon, in 1810 – already much later than its equivalent in England – and continued even after he was ousted
and well into the late 19th century. And that leads to a really interesting social side-effect.
My brief interest in 19th century Dutch tax policy was piqued during my team’s boat tour.
Glass manufacturing technique evolved rapidly during the 19th century. At the start of the century, when England’s window tax law was in full swing, glass panes were typically made
using the crown glass process: a bauble of glass would be
spun until centrifugal force stretched it out into a wide disk, getting thinner towards its edge.
The very edge pieces of crown glass were cut into triangles for use in leaded glass, with any useless offcuts recycled; the next-innermost pieces were the thinnest and clearest, and
fetched the highest price for use as windows. By the time you reached the centre you had a thick, often-swirly piece of glass that couldn’t be sold for a high price: you still sometimes
find this kind among the leaded glass in particularly old pub windows5.
They’re getting rarer, but I’ve lived in houses with small original panes of crown glass like these!
As the 19th century wore on, cylinder glass became the norm. This is produced by making an iron cylinder as a mould, blowing glass into it, and then carefully un-rolling the cylinder
while the glass is still viscous to form a reasonably-even and flat sheet. Compared to spun glass, this approach makes it possible to make larger window panes. Also: it scales
more-easily to industrialisation, reducing the cost of glass.
The Dutch window tax survived into the era of large plate glass, and this lead to an interesting phenomenon: rather than have lots of windows, which would be expensive,
late-19th century buildings were constructed with windows that were as large as possible to maximise the ratio of the amount of light they let in to the amount of tax for which
they were liable6.
Look at the size of those windows! If you’re limited in how many you can have, but you’ve got the technology, you’re going to make them as large as you possibly can!
That’s an architectural trend you can still see in Amsterdam (and elsewhere in Holland) today. Even where buildings are renovated or newly-constructed, they tend – or are required by
preservation orders – to mirror the buildings they neighbour, which influences architectural decisions.
Notice how each building has only between one and three windows on the ground floor, letting as much light in while minimising the tax burden.
It’s really interesting to see the different architectural choices produced in two different cities as a side-effect of fundamentally the same economic choice, resulting from slightly
different starting conditions in each (a half-century gap and a land shortage in one). While Britain got fewer windows, the Netherlands got bigger windows, and you can still see the
effects today.
…and social status
But there’s another interesting this about this relatively-recent window tax, and that’s about how people broadcast their social status.
This Google Street Canal (?) View photo shows a house on Keizersgracht, one of the richest parts of Amsterdam. Note the superfluous decorative window above the front door
and the basement-level windows for the servants’ quarters.
In some of the traditionally-wealthiest parts of Amsterdam, you’ll find houses with more windows than you’d expect. In the photo above, notice:
How the window density of the central white building is about twice that of the similar-width building on the left,
That a mostly-decorative window has been installed above the front door, adorned with a decorative
leaded glass pattern, and
At the bottom of the building, below the front door (up the stairs), that a full set of windows has been provided even for the below-ground servants quarters!
When it was first constructed, this building may have been considered especially ostentatious. Its original owners deliberately requested that it be built in a way that would attract a
higher tax bill than would generally have been considered necessary in the city, at the time. The house stood out as a status symbol, like shiny jewellery, fashionable clothes,
or a classy car might today.
I originally wanted to insert a picture here that represented how one might show status through fashion today. But then I remembered I don’t know anything about fashion7. But somehow my stock image search suggested this photo, and I
love it so much I’m using it anyway. You’re welcome.
How did we go wrong? A century and a bit ago the super-wealthy used to demonstrate their status by showing off how much tax they can pay. Nowadays, they generally seem
more-preoccupied with getting away with paying as little as possible, or none8.
Can we bring back 19th-century Dutch social status telegraphing, please?9
Footnotes
1 Following the Treaty of Union the window tax was also applied in Scotland, but
Scotland’s a whole other legal beast that I’m going to quietly ignore for now because it doesn’t really have any bearing on this story.
2 The second-hardest thing about retrospectively graphing the cost of window tax is
finding a reliable source for the rates. I used an archived copy of a guru site about Wolverhampton history.
3 Even relatively-recently, the argument that income tax might be repealed as incompatible
with British values shows up in political debate. Towards the end of the 19th century, Prime Ministers Disraeli and Gladstone could be relied upon to agree with one another on almost
nothing, but both men spoke at length about their desire to abolish income tax, even setting out plans to phase it out… before having to cancel those plans when some
financial emergency showed up. Turns out it’s hard to get rid of.
4 There are, of course, other potential reasons for bricked-up windows – even aesthetic ones – but a bit of a giveaway is if the bricking-up
reduces the number of original windows to 6, 9, 14 or 19, which are thesholds at which the savings gained by bricking-up are the greatest.
5 You’ve probably heard about how glass remains partially-liquid forever and how this
explains why old windows are often thicker at the bottom. You’ve probably also already had it explained to you that this is complete bullshit. I only
mention it here to preempt any discussion in the comments.
6 This is even more-pronounced in cities like Amsterdam where a width/frontage tax forced
buildings to be as tall and narrow and as close to their neighbours as possible, further limiting opportunities for access to natural light.
7 Yet I’m willing to learn a surprising amount about Dutch tax law of the 19th century. Go
figure.
I’ve got a (now four-year-old) Unraid NAS called Fox and I’m a huge fan. I particularly love the fact that Unraid can work not only as a NAS, but also as a fully-fledged Docker appliance, enabling me to easily install and maintain all manner of applications.
There isn’t really a generator attached to Fox, just a UPS battery backup. The sign was liberated from our shonky home electrical system.
I was chatting this week to a colleague who was considering getting a similar setup, and he seemed to be taking notes of things he might like to install, once he’s got one. So I figured
I’d round up five of my favourite things to install on an Unraid NAS that:
Don’t require any third-party accounts (low dependencies),
Don’t need any kind of high-powered hardware (low specs), and
Provide value with very little set up (low learning curve).
It’d have been cooler if I’d have secretly written this blog post while sitting alongside said colleague (shh!). But sadly it had to wait until I was home.
Syncthing’s just an awesome piece of set-and-forget software that facilitates file synchronisation between all of your devices and can also form part of a backup strategy.
Here’s the skinny: you install Syncthing on several devices, then give each the identification key of another to pair them. Now you can add folders on each and “share” them with the
others, and the two are kept in-sync. There’s lots of options for power users, but just as a starting point you can use this to:
Manage the photos on your phone and push copies to your desktop whenever you’re home (like your favourite cloud photo sync service, but selfhosted).
Keep your Obsidian notes in-sync between all your devices (normally costs $4/month).1
Get a copy of the documents from all your devices onto your NAS, for backup purposes (note that sync’ing alone, even with
versioning enabled, is not a good backup: the idea is that you run an actual backup from your NAS!).
You know IFTTT? Zapier? Services that help you to “automate” things based on inputs and outputs. Huginn’s like that, but selfhosted.
Also: more-powerful.
When we first started looking for a dog to adopt (y’know, before we got this derper), I set up Huginn watchers to monitor the websites of several rescue centres, filter them by some of our criteria, and push
the results to us in real-time on Slack, giving us an edge over other prospective puppy-parents.
The learning curve is steeper than anything else on this list, and I almost didn’t include it for that reason alone. But once you’ve learned your way around its idiosyncrasies and
dipped your toe into the more-advanced Javascript-powered magic it can do, you really begin to unlock its potential.
It couples well with Home Assistant, if that’s your jam. But even without it, you can find yourself automating things you never expected to.
Many of these suggested apps benefit well from you exposing them to the open Web rather than just running them on your LAN,
and an RSS reader is probably the best example (you want to read your news feeds when you’re out and about, right?). What you
need for that is a reverse proxy, and there are lots of guides to doing it super-easily, even if you’re not on a static IP
address.2.
Alternatively you can just VPN in to your home: your router might be able to arrange this, or else Unraid can do it for you!
You know how sometimes you need to give somebody your email address but you don’t actually want to. Like: sure, I’d like you to email me a verification code for this download, but I
don’t trust you not to spam me later! What you need is a disposable email address.3
How do you feel about having infinite email addresses that you can make up on-demand (without even having access to a computer), subscribe to by RSS, and never have to see unless you specifically want to.
You just need to install Open Trashmail, point the MX records of a few domain names or subdomains (you’ve got some spare domain names
lying around, right? if not; they’re pretty cheap…) at it, and it will now accept email to any address on those domains. You can make up addresses off the top of your head,
even away from an Internet connection when using a paper-based form, and they work. You can check them later if you want to… or ignore them forever.
Couple it with an RSS reader, or Huginn, or Slack, and you can get a notification or take some action when an email arrives!
Need to give that escape room your email address to get a copy of your “team photo”? Give them a throwaway, pick up the picture when you get home, and then forget you ever gave it
to them.
Company give you a freebie on your birthday if you sign up their mailing list? Sign up 366 times with them and write a Huginn workflow that puts “today’s” promo code into your
Obsidian notetaking app (Sync’d over Syncthing) but filters out everything else.
Suspect some organisation is selling your email address on to third parties? Give them a unique email address that you only give to them and catch them in a honeypot.
It isn’t pretty, but… it doesn’t need to be! Nobody actually sees the admin interface except you anyway.
Plus, it’s just kinda cool to be able to brand your shortlinks with your own name, right? If you follow only one link from this post, let it be to watch this video
that helps explain why this is important: danq.link/url-shortener-highlights.
I run many, many other Docker containers and virtual machines on my NAS. These five aren’t even the “top five” that I
use… they’re just five that are great starters because they’re easy and pack a lot of joy into their learning curve.
And if your NAS can’t do all the above… consider Unraid for your next NAS!

1 I wrote the beginnings of this post on my phone while in the Channel Tunnel and then
carried on using my desktop computer once I was home. Sync is magic.
2 I can’t share or recommend one reverse proxy guide in particular because I set my own up
because I can configure Nginx in my sleep, but I did a quick search and found several that all look good so I imagine you can do the same. You don’t have to do it on day one, though!
Like much of the UK, there are local elections where I live next month. After coming home from a week of Three Rings volunteering I found my poll card on the doormat. Can you spot the bleeding-obvious mistake?
Also interesting was that this year the poll card came in a tamper-evidence tear-to-open envelope rather than just being a piece of card. Does the government now think that postal
workers are routinely stealing voter identities? Cohabitees?
This’ll be the first election for which I’ve needed to bring photographic ID to the polling station. That shouldn’t be a problem: I have a passport and driving license and whatnot.
But just to be absolutely certain, I had the local council – the same people who issued me the polling card! – supply me with a voter authority certificate:
Note that this document, also issued by West Oxfordshire District Council, spells my name correctly.
So now I’m in a pickle. West Oxfordshire District Council are asking me to produce photo ID in the wrong name when I turn up at a polling station next month. It doesn’t even
match the name on the photo ID that they themselves issued me.
This would be less-infuriating were it not for the fact that they had my name wrong in the same way on an electoral roll form they sent me in August 20221.
When I contacted them to have them fix it, they promised that the underlying problem was solved2
so this very thing wouldn’t happen.
And yet here we are.
Hopefully they’ll be able to fix their records promptly or else I guess I’ll have to apply for a proxy vote, to allow the ballot of my imaginary friend “Dan Que” to be cast by me, Dan
Q, instead.
And if that isn’t the most bizarre form of election fraud you’ve ever heard of, I don’t know what is.
Update: True to their word, the council had managed to
correct their records by the time I reached the polling station this morning. It’s still a little annoying that they somehow mucked it up in the first place, but I appreciate the
efficiency with which they corrected their mistake.
Footnotes
1 They’d had my name right before August 2022, including on previous poll cards;
I can only assume that some human operator “corrected” it to the wrong thing at some point.
2 They didn’t fix the problem immediately in August 2022. Initially, they
demanded that I produce proof of my change of name from “Dan Que” (which has, of course, never been my name!) to “Dan Q”, and only later backed down and admitted that they’d
made a mistake and would correct the PII they were holding about me.
Anyway, here’s the best printer for 2024: a Brother laser printer. You can just pick any one you like; I have one with a sheet feeder and one without a sheet feeder. Both of them have
reliably printed return labels and random forms and pictures for my kid to color for years now, and I have never purchased replacement toner for either one. Neither has fallen off the
WiFi or insisted I sign up for an ink-related hostage situation or required me to consider the ongoing schemes of HP executives who seem determined to make people hate a legendary
brand with straightforward cash grabs and weird DRM ideas.
…
It’s sort-of alarming that Brother are the only big player in the printer space who subscribe to a philosophy of “don’t treat the customers like
livestock”. Presumably all it’d take is a board-level decision to flip the switch from “not evil” to “evil” and we’d lose something valuable. Thankfully, for now at least, they still
clearly see the value of the positive marketing the world gives them. Positive marketing like like this article.
The article is excellent, by the way. I know that I’m “supposed” to stir up hatred about the fact that its conclusion is written by an AI but… well, just read it for yourself and you’ll see why I don’t mind even one bit. Top notch reporting. Consider following the links within it to
stories about how other printer manufacturers continue to show exactly how shitty they can be.
I recommended a Brother printer to the Vagina Museum the other month. I assume it ‘s still working out fine for them (and not ripping them off, spying on them, and/or contributing to the
destruction of the the planet).
