This checkin to GC8TNPE Incy Wincy reflects a geocaching.com log entry. See more of Dan's cache logs.
The elder child and I are staying nearby and couldn’t resist coming to a nearby cache with so many FPs. The name gave us a bit of a clue what we would be looking for but nothing could have prepared us for for this imaginative and unusual container! FP awarded. Attached is very non-spoiler photo of us with our very own Incy Wincies. Greetings from Oxfordshire!
RotatingSandwiches.com is a website showcasing animated GIF files of rotating sandwiches1. But it’s got a problem: 2 of the 51 sandwiches rotate the wrong way. So I’ve fixed it:
My fix is available as a userscript on GreasyFork, so you can use your favourite userscript manager2 to install it and the rotation will be fixed for you too. Here’s the code (it’s pretty simple):
1 2 3 4 5 6 7 8 9 10 11 12 |
// ==UserScript== // @name Standardise sandwich rotation on rotatingsandwiches.com // @namespace rotatingsandwiches.com.danq.me // @match https://rotatingsandwiches.com/* // @grant GM_addStyle // @version 1.0 // @author Dan Q <https://danq.me/> // @license The Unlicense / Public Domain // @description Some sandwiches on rotatingsandwiches.com rotate in the opposite direction to the majority. 😡 Let's fix that. // ==/UserScript== GM_addStyle('.q23-image-216, .q23-image-217 { transform: scaleX(-1); }'); |
Unless you’re especially agitated by irregular sandwich rotation, this is perhaps the most-pointless userscript ever created. So why did I go to the trouble?
Obviously, I’m telling you this as a vehicle to talk about userscripts in general and why you should be using them.
Userscripts fix and improve websites for you. Whether you want to force Reddit to stay “old Reddit” as long as possible, make Geocaching.com’s maps more-powerful, show Twitter images uncropped by default, re-add the “cached” link to Google search results, show prices on shopping sites in terms of hours-of-your-life of work they “cost”, or just automatically click Netflix’s “yes, I’m still here, keep playing” button for maximum binge-mode, there’s a script for you. They’re like tiny browser plugins.
But the real magic is being able to remix the web your way. With just a little bit of CSS or JavaScript experience you can stop complaining that a website’s design has changed in some way you don’t like or that some functionality you use isn’t as powerful or convenient as you’d like and you can fix it.
A website I used disables scrolling until all their (tracking, advertising, etc.) JavaScript loads, and my privacy blocker blocks those files: I could cave and disable my browser’s
privacy tools… but it was almost as fast to add setInterval(()=>document.body.style.overflow='', 200); to a userscript and now it’s fixed.
Don’t want a Sports section on your BBC News homepage (not just the RSS
feed!)? document.querySelector('a[href="/sport"]').closest('main > div').remove(). Sorted.
I’m a huge fan of building your own tools to “scratch your own itch”. Userscripts are a highly accessible introduction to doing so that even beginner programmers can get on board with and start getting value from. More-advanced scripts can do immensely clever and powerful things, but even if you just use them to apply a few light CSS touches to your favourite websites, that’s still a win.
1 Remember when a website’s domain name used to be connected to what it was for? RotatingSandwiches.com does.

I thought it might be fun to try to map the limits of my geocaching/geohashing. That is, to draw the smallest possible convex polygon that surrounds all of the geocaches I’ve found and geohashpoints I’ve successfully visited.
Mathematically, such a shape is a convex hull – the smallest polygon encircling a set of points without concavity. Here’s how I made it:
1. Extract all the longitude/latitude pairs for every successful geocaching find and geohashpoint expedition. I keep them in my blog database, so I was able to use some SQL to fetch them:
SELECT DISTINCT coord_lon.meta_value lon, coord_lat.meta_value lat FROM wp_posts LEFT JOIN wp_postmeta expedition_result ON wp_posts.ID = expedition_result.post_id AND expedition_result.meta_key = 'checkin_type' LEFT JOIN wp_postmeta coord_lat ON wp_posts.ID = coord_lat.post_id AND coord_lat.meta_key = 'checkin_latitude' LEFT JOIN wp_postmeta coord_lon ON wp_posts.ID = coord_lon.post_id AND coord_lon.meta_key = 'checkin_longitude' LEFT JOIN wp_term_relationships ON wp_posts.ID = wp_term_relationships.object_id LEFT JOIN wp_term_taxonomy ON wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id LEFT JOIN wp_terms ON wp_term_taxonomy.term_id = wp_terms.term_id WHERE wp_posts.post_type = 'post' AND wp_posts.post_status = 'publish' AND wp_term_taxonomy.taxonomy = 'kind' AND wp_terms.slug = 'checkin' AND expedition_result.meta_value IN ('Found it', 'found', 'coordinates reached', 'Attended');
2. Next, I determine the convex hull of these points. There are an interesting variety of algorithms for this so I adapted the Monotone Chain approach (there are convenient implementations in many languages). The algorithm seems pretty efficient, although that doesn’t matter much to me because I’m caching the results for a fortnight.
3. Finally, I push the hull coordinates into Geoapify, who provide mapping services to me. My full source code is available.
An up-to-date (well, no-more than two weeks outdated) version of the map appears on my geo* stats page. I don’t often get to go caching/hashing outside the bounds already-depicted, but I’m excited to try to find opportunities to push the boundaries outwards as I continue to explore the world!
(I could, I suppose, try to draw a second larger area of places I’ve visited: the difference between the smaller and larger areas would represent all of the opportunities I’d missed to find a hashpoint!)

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).

This “choose your own adventure”-style game about making the perfect cup of tea is just… excellent.
If you lack the imagination to understand how a game like this could have dozens of possible endings, you desperately need to play it. My favourite path so far through the game was to add a teabag, then hot water, then remove the teabag, then add some milk, then add a second teabag, then drink it.
Genuinely can’t stop laughing at this masterpiece.
Sometimes you just gotta have exactly the right prop for a presentation…
I’m testing a handful of highly-experimental new features on my personal website using multivariate (“A/B”) testing.
If you visit within the next day or so you’re likely to be randomly-selected to try out one of them. (If you’re not selected, you can manually enable one of the experiments.)
I’d love to hear your feedback on these Very Serious New Features! Let me know which one(s) you see and whether you think they should become permanent fixtures on my site.

This promotional video for Aberystwyth University has been kindly archived onto YouTube by one of the undergraduate students who features in it. It was produced in 1984; approximately the same time I first visited Aberystwyth, although it would take until fifteen years later in 1999 for me to become a student there myself.
But the thing is… this 1984 video, shot on VHS in 1984, could absolutely be mistaken at-a-glance for a video shot on an early digital video camera a decade and a half later. The pace of change in Aberystwyth was and is glacial; somehow even the fashion and music seen in Pier Pressure in the video could pass for late-90s!
Anyway: I found the entire video amazingly nostalgic in spite of how far it predates my attendance of the University! Amazing.
What they say: “This site works better in our app.”
What they mean (optimistic): “We couldn’t be bothered to make a good website.”
What they mean (realistic): “We can track and monetise you better if we can coerce you into installing this.”
I was contacted this week by a geocacher called Dominik who, like me, loves geocaching…. but hates it when the coordinates for a cache are hidden behind a virtual jigsaw puzzle.
A popular online jigsaw tool used by lazy geocache owners is Jigidi: I’ve come up with several techniques for bypassing their puzzles or at least making them easier.
Dominik had been looking at a geocache hidden last week in Eastern France and had discovered that it used JigsawExplorer, not Jigidi, to conceal the coordinates. Let’s take a look…
I experimented with a few ways to work-around the jigsaw, e.g. dramatically increasing the “snap range” so dragging a piece any distance would result in it jumping to a neighbour, and extracting original image URLs from localStorage. All were good, but none were perfect.
Then I realised that – unlike Jigidi, where there can be a congratulatory “completion message” (with e.g. geocache coordinates in) – in JigsawExplorer the prize is seeing the completed jigsaw.
Let’s work on attacking that bit of functionality. After all: if we can bypass the “added challenge” we’ll be able to see the finished jigsaw and, therefore, the geocache coordinates. Like this:
jigex-prog.js file. Right-click and select Override Content (or Add Script Override).
e&&e.customMystery?tt.msgbox("This puzzle's box top preview is disabled for added challenge."): –
this code checks if the puzzle has the “custom mystery” setting switched on and if so shows the message, otherwise (after the :) shows the box cover.
The moral, as always, might be: don’t put functionality into the client-side JavaScript if you don’t want the user to be able to bypass it.
Or maybe the moral is: if you’re going to make a puzzle geocache, put some work in and do something clever, original, and ideally with fieldwork rather than yet another low-effort “upload a picture and choose the highest number of jigsaw pieces to cut it into from the dropdown”.
Ever wondered why Oxford’s area code is 01865? The story is more-complicated than you’d think.
I’ll share the story on my blog, of course. But before then, I’ll be telling it from the stage of the Jericho Tavern at 21:15 on Wednesday 17 April as my third(?) appearance at Oxford Geek Nights! So if you’re interested in learning about some of the quirks of UK telephone numbering history, I can guarantee that this party’s the only one to be at that Wednesday night!
Not your jam? That’s okay: there’s plenty of more-talented people than I who’ll be speaking, about subjects as diverse as quantum computing with QATboxen, bringing your D&D experience to stakeholder management (!), video games without screens, learnings from the Horizon scandal, and whatever Freyja Domville means by The Unreasonable Effectiveness of the Scientific Method (but I’m seriously excited by that title).
Anyway: I hope you’ll be coming along to Oxford Geek Nights 57 next month, if not to hear me witter on about the fossils in our telecommunications networks then to enjoy a beer and hear from the amazing speakers I’ll be sharing the stage with. The event’s always a blast, and I’m looking forward to seeing you there!
There are two junctions at which I can join the A40 trunk road from my house. When I drive East, I use the Easternmost of the two; when I drive West, I use the Westernmost; but I almost never drive the stretch of road between them!
A few years ago I generated heatmaps of my movements based on my long-running personal location log and, indeed, it shows a “cool spot” along this section of road too:
It’s inevitable I suppose that there should exist a “road (segment) less-travelled” right on my doorstep, but it still feels strange. Like when you live near a tourist attraction that you never get around to visiting. Except instead of a tourist attraction, I live near a major highway I rarely use.
Maybe I’m missing out on something great. Probably the commuters who use that road to get into and out of Oxford don’t think so.
This checkin to GC2BHX9 C-130J Hercules reflects a geocaching.com log entry. See more of Dan's cache logs.
Found by the geohound and I after a brief battle with the first stinging nettles of the season. Owie! She and I came over from Stanton Harcourt this morning – from which we see plenty of Brize Nortons’ Hercules! – because many of our favourite local walks are waterlogged. Things are somewhat drier underfoot here, but after our walk through the fields the pup and I are still rather muddy! TFTC.
This checkin to GC6Q3A1 Cur.Bri.Lew 11 reflects a geocaching.com log entry. See more of Dan's cache logs.
The pup and I unearthed a few likely hiding places without success here. Not sure what we’ve missed: feels like we lifted every hint item in the vicinity!

QEF for the geopup and I on this strangely springlike morning. Cache container is damaged almost beyond recognition, as others have observed, and is desperately in need of replacement. TFTC.
