The Miracle Sudoku

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

I first saw this video when it was doing the rounds three years ago and was blown away. I was reminded of it recently when it appeared in a blog post about AI’s possible future role in research by Terence Eden.

I don’t even like sudoku. And if you’d told me in advance that I’d enjoy watching a man slowly solve a sudoku-based puzzle in real-time, I’d have called you crazy. But I watched it again today, for what must’ve been the third time, and it’s still magical. The artistry of puzzle creator Mitchell Lee is staggering.

If you somehow missed it the first time around, now’s your chance. Put this 25-minute video on in the background and prepare to have your mind blown.

Making a Home of Each Other (The Eggs)

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

I dislike recipe posts that, before you get anywhere near the list of ingredients, tell you what feels like the entire life story of the author and their family.

“Every morning my mother would warm up the stove, and this was a wood-fired stove back in the day, and make these. We lived in Minnosota…” I don’t care. I can’t begin to tell you how much I don’t care. Just tell me how to make the damn muffins ‘cos the picture’s got me drooling.

This is different. This is the latest and so-far only exception. This, I care about:

When we moved into a house of our own, I bought us a tea kettle that whistled in harmony when it boiled. Rent was cheap, and we were happy. Those were the days of sweet potato hash, wilted kale, and increasingly exotic baked goods. There was the Me-Making-You-Tea-in-the-Morning-Because-You-Hated-Mornings Phase, but also the You-Making-Me-Tea-in-the-Morning-Because-You-Went-to-Work-at-5am Phase.

Lucy tells a story so rich and personal about her and her wife’s experience of life, cohabitation, food, and the beauty of everyday life. I haven’t even read the recipe for The Eggs, even though it sounds pretty delicious.

Over the years I’ve found words for people who have done what we’re doing now, but I’ve also found a deeper truth: our queer community doesn’t demand a definition. They know that chili oil can change a life just as much as a marriage. That love is in the making and unmaking of beds. The candlelit baths. The laughter. The proffered feast that nourishes.

Queerness makes room within it for these relationships, or rather: queerness spirals outward. It blooms and embraces. That is the process by which we broaden our palates, welcoming what might seem new to us, but which is actually older than we know.

It’s a great reminder about focussing on what’s important. About the value of an ally whether the world’s working with you or against you. And, of course, about how every relationship, no matter what shape, size, or form, can enjoy a little more queering once in a while. Go read it.

Thoughts on Editing Posts

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

I edit all my posts before I publish them – I look for poor grammar, me rambling on (something which I’m terrible for) and things like typos, although some do still get through. I think that kind of editing is fine.

But when it comes to opinion pieces, I don’t think they should be edited. Yes, you should (in my opinion) check the spelling/grammar before posting, but I don’t think you should go back and edit your opinions retrospectively if they change.

Kev speaks my mind.

At almost 25 years ago, my blog’s ancient, and covering more than half my life it inevitably includes posts that I feel don’t accurately reflect me any more (or, perhaps, didn’t reflect me well even when I wrote them!). My approach has long been that it’s okay to go back and modify a post to:

  • Correct spelling, punctuation, and grammar, or improve readability without changing the meaning.
  • Add content (in a clearly-marked way) to improve context, update information, or prepend/append hyperlinks to updated information.
  • Make changes that protect an individual (e.g. removing the name or photo of somebody who doesn’t want to be identified).

But like Kev, to me it just doesn’t seem right to change opinion pieces after your opinion changes. I’m happy to write a retraction and link to it from the original, but making-out like I never said those things in the first place seems disingenuous.

Kev links a disclaimer from his older posts; that’s an interesting idea that I might adopt.

This was a delightful vlog. It really adds personality to what might otherwise have been a story only about technology and history.

Automattic Acquires ActivityPub Plugin for WordPress

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

Automattic has acquired the ActivityPub plugin for WordPress from German developer Matthias Pfefferle, who will be joining the company to continue improving support for federated platforms. Pfefferle, who is also the author of the Webmention plugin, said his new role is to see how Automattic’s products can benefit from open protocols like ActivityPub.

This is so exciting I might burst. Want to know why?

  1. Matt Mullenweg‘s commitment to ActivityPub makes me happy. WordPress made Pingback and Trackback take off, back in the day, and I believe that – in the same way – Automattic can help make ActivityPub more accessible and mainstream too.
  2. Matthias Pfefferle is both an IndieWeb and an ActivityPub star; I use (and I’ve extented upon) a lot of code he’s written every day and I sponsor him on Github! The chance that we get to work directly together is pretty slim, but it’s a chance right?

Susan A. Kitchens expressed concern that this could increase the level of ActivityPub spam out there (which right now is very low). I worry about that too. But I’m still optimistic that we can make something awesome off the back of this acquisition and keep the interpersonal Web federated, the way it ought to be.

The tape library robot that served drinks

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

This is an IBM tape library robot. It’s designed to fetch, load, unload, and return tape media cartridges to the correct bay in large enterprise environments.

One fateful ‘workend’, I made one serve drinks.

It went back into prod on the Monday…

In a story reminiscient of those anecdotes about early computer science students competing to “race” hard drives across the lab by writing programs that moved the heads in a way that vibrated/walked the devices, @SecurityWriter shares a wonderful story about repurposing a backup tape management robot to act as a server (pun intended) of drinks.

Kev Quirk: Ten Years of Blogging

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

If you read a lot of the “how to start a blog in 2023” type posts (please don’t ever use that title in a post) the advice will often boil down to something like:

  • Choose a niche
  • Start collecting email addresses immediately (newsletter)
  • Write on a regular schedule

I don’t do any of those things. 😂

Kev writes about what he’s learned from ten years of blogging. As a fellow long-term blogger1, I was especially pleased with his observation that, for some (many?) of us old hands, all the tips on starting a blog nowadays are things that we just don’t do, sometimes deliberately.

Like Kev, I don’t have a “niche” (I write about the Web, life, geo*ing, technology, childwrangling, gaming, work…). I’ve experimented with email subscription but only as a convenience to people who prefer to get updates that way – the same reason I push articles to Facebook – and it certainly didn’t take off (and that’s fine!). And as for writing on a regular schedule? Hah! I don’t even manage to be uniform throughout the year, even after averaging over my blog’s quarter-century2 of history.

Also like Kev, and I think this is the reason that we ignore these kinds of guides to blogging, I blog for me first and foremost. Creation is a good thing, and I take my “permission to write” and just create stuff. Not having a “niche” means that I can write about what interests me, variable as that is. In my opinion the only guide to starting a blog that anybody needs to read is Andrew Stephens“So You Want To Start An Unpopular Blog”.

And if that’s not enough inspiration for you to jump back in your time machine and party like the Web’s still in 2005, I don’t know what is.

1 I celebrated 20 years… a while back?

2 Fuck me, describing a blog as having about a quarter-century of history makes it sound real old.

Transferring to a new phone network, 2022 edition

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

…removing a SIM tray is harder than it looks when you don’t wear earrings. I had to search everywhere to find one of those little SIM tools…

Stuart writes a fun article about his experience of changing mobile network. It’s worth a read, and there’s only one “Dan pro tip” I’d add:

If you have a case on your mobile phone, tuck one of those SIM extractor tools into the case, behind your phone. It’s exactly where you need it to be, if you need one yourself (you probably need to remove the case to access the SIM tray anyway), but beyond that: it means you’re always carrying one for when a friend needs one. They’re also useful for pressing those tiny “factory reset” buttons you see sometimes.

A SIM extractor has been sneakily part of my “everyday carry” for about a decade and it’s proven its value time and time again.

When Twitter Loses, WordPress Wins

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

You know who’s having a killer month? Automattic. Everyone who’s leaving Twitter seem to fall in at least one of these three camps:

  1. They have gone back to the blogosphere. (using WordPress, or WordPress.com)
  2. They have gone to Tumblr
  3. They have gone to the fediverse (of which a fairly large percentage are WordPress installs)

In all of these cases, Automattic wins.

Some smart observations here by Alex. A fourth point worth noting is that Matt has openly suggested that former Twitter engineers might like to come join us in Automattic and help make the web a better place. We’ve changed our careers pages a little lately but we’re still the same awesome company!

Alex went on to say:

I’ll be downright shocked if Matt isn’t working very hard to get Tumblr on the fediverse ASAP. He has so much to gain in supporting this movement, and very little to lose.

That’s definitely on his mind too, which I can safely say without leaking anything because he’s hinted at it himself. Exciting times.

Debugging Mysteries

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

Just wanted to share with you something I found ages ago but only just got around to mentioning – Julia Evans‘ (of Wizard Zines fame) Debugging Mysteries:

There are five mysteries here right now:

The Case of the Slow Websites
The Case of the Connection Timeout
The Case of the DNS Update that Didn’t Work
The Case of the 50ms Request
The Case of the Failed Docker Connection

Go back to wizardzines.com

GitHub repository: jvns/twine-stories
Blog post about this project: Notes on building debugging puzzles

Each mystery is a Twine-powered “choose your own adventure” game in which you must diagnose the kind of issue that a software developer might, for real. I think these are potentially excellent tools for beginner programmers, not just because they provide some information about the topic of each, but because they encourage cultivating a mindset of the kind of thinking that’s required to get to the bottom of gnarly problems.

Better yet, she’s open-sourced the entire thing (and I was excited to see she wrote in Twee, which is very dear to my heart).

How Chinese citizens use puns to get past internet censors

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

A few months ago, people were posting a lot about the Netherlands on Chinese social media platform Weibo. “Wake up, sleeping people of the Netherlands!” said one post. Others lamented that the people of Amsterdam wanted their tulips back.

These Chinese social media users aren’t expressing a nascent interest in all things Dutch. They’re talking about recent protests over frozen bank deposits in the province of Henan. Ordinarily, discussions about a controversial topic like this would be censored on Chinese social media, and posts containing the word “Henan” could be blocked or deleted. But “Henan” (河南) sounds a lot like “Helan” (荷兰), the Mandarin word for the Netherlands. By swapping the names around, people were able to get past the censors and keep the conversation going.

I love this article. The use of homonyms and puns to work around online censorship by Chinese citizens is as innovative and heartwarming as its necessity is horrifying and tragic. If you’re wondering exactly how similar 河南 (“Henan”, the name of the Chinese province in which authorities abused social distancing laws and used violence to prevent rural bank customers from withdrawing their own money) and 荷兰 (“Helan”, The Netherlands) sound, have a listen for yourself:

Unless you speak Mandarin already, you’ll might struggle to even pinpoint which is which in that recording.

This clever and imaginative use of language to try to sidestep surviellance feels like a modern adaptation of cryptolects like Polari or rhyming slang as used in the UK for the same purpose. But writing in Han characters online seems to provide an amazingly diverse way to encode meaning that an in-the-know human can parse, but an automated machine or an uninformed human censor can not. The story about the use of the word for “paratrooper” on Chinese social media, touched upon in the article linked above and expanded elsewhere, is particularly enjoyable.

Anyway, after you’ve read the article and you’re ready for a whole new rabbit whole to explore, I’d like to kickstart you by introducing you to Totoiana, a Pig Latin-like (second-syllable onwards, then first syllable) dialect spoken with fluency exclusively in a single Romanian village, and nobody knows why.

You’ve got 37 unpaid parking tickets. You just got pulled over for speeding. In your defense, you were texting your sister about how drunk you are. Plus there’s all that blood on your windshield. Obviously you know it’s deer blood, but the police officers walking toward your vehicle don’t. Still, in the time it takes them to figure that out, maybe you’ll sober up. Or escape on foot! Either way, it’ll probably be fine.

You’d better hope it’s not the owner of the live seagull zoo down the street, because he’s probably got some questions.

Bree-Yark!

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

JTA tweeted a brilliant thread about something he discovered while digging through old D&D texts, and it’s awesome so – as I imagine he wouldn’t mind – I’ve reproduced it in full here:

I don’t really Twitter so much these days because like most social media it makes me either gloomy or extremely grumpy with the state of the world, but since I also lack the time to bother blogging anywhere, here’s a ludicrously nerdy thread about a Dungeons & Dragons rumour.So, back in the days of AD&D 1st Edition your printed modules would often come with a table of Rumours. The idea was hearing rumours increased the depth of the world, so players didn’t feel like NPCs just winked into existence when they entered the Hydra’s Den tavern & said “hi”.

But sometimes the rumours would be false, or exaggerated. That also added depth and had the bonus of ensuring that players didn’t take it for granted. OK, this guy in the red robe *says* Kobolds are poisoning the iron ore, but is that at all plausible, or is it just a bad seam?

(Those of us without any friends, or at least without friends equally into D&D in the 80s & 90s, also got this experience because it was well-replicated in the TSR Gold Box series of games, either in-game, or more-commonly through supplementary material in the boxes.

The supplementary materials often came in a separate “Journal” supplied in the box, & were a sort of additional layer of copy-protection because if the Game says “read Entry 19”, your choice is either do so, or wait 25 years for the abandonware PDFs to hit archive.org.

e.g., here’s the Traveller’s Tales from ‘Curse of the Azure Bonds’: note the subtlety of entries 1 and 8, about the Princess, sounding corroborative – maybe encouraging the party to more deference around someone with purple in their clothes, though either or both might be false.)

A selection of Tavern Tales...

Anyway, this only really existed in the TSR/SSI games because it was in the standard modules.

I was reminded of the rumour system when I was digging back into AD&D Module B2: The Keep on the Borderlands to borrow a bunch of content for a campaign I’ve just inherited (as you do)

‘Keep on the Borderlands’ was by Gary Gygax himself, and suffers a bunch from the typical issues 1e had, none of which I’ll address here because I would please nobody. But the rumours table is a really good example of the type – it gives players depth but not unfair advantages.

The Rumour Table from the A...

Now Keep on the Borderlands was a pretty big deal of a module back in the day. It was module B2, of the Basic Set, & it did some stuff really well, especially for new players – sort of a 1980 equivalent of ‘Lost Mine of Phandelver’ today. Lots of players cut their teeth on it.

Rumour 10 – ‘”Bree-Yark” is goblin-language for “we surrender”!’ – is a false rumour, though the party doesn’t know that: whatever ‘Bree-yark’ means, it’s not “We Surrender”.

In fact, the module tells the DM it means “Hey, rube!!” and is used by goblins to sound the alarm.

(Spoilers here for the Goblin Lair in Location D of the Caves of Chaos, but when goblins on watch call out “Bree-yark!”, more goblins at #18 will bribe an ogre to come help attack the party. (1e often imposed dynamic worlds by fiat, back when the world was young, the DMs green)

The DM's description for Lo...

So lots of early DMs got to imagine the potential hilarity of the party arriving in the cave, hearing goblins apparently surrendering, & dropping their guard, never realising life just got harder!

(It isn’t much hilarity, but in the 80s, as now, there was limited scope for joy)

Still – it’s a decent joke. Everyone believes “Bree-yark” is Goblin for surrender, but it isn’t really, that’s just a false rumour, spread by boastful drunks who’ve never seen a goblin in real life anyway.

So much for 1st Edition AD&D, I guess.

…except:

It’s 2014. The wheel of time turns, ages come and pass, and Grapple rules don’t so much become legend as “remain completely incomprehensible”. Now every new adventurer carries a Field Marshall’s baton in their knapsack, ‘cos tracking encumbrance is for chumps, & D&D 5e launches.

(While I’m doing archaeology, take a moment in this fast-forward to enjoy the glorious madness of the Grimtooth’s Traps series, which popped up in ’81 & features brilliantly inventive nastiness to spring on players who aren’t too attached to their character sheets. Or friends.)

A page from 1981's Grimtoot...

So, 5e launches, to a lot of stick in some circles (I never knew a version of D&D that didn’t: probably some wazzock in 1971 ranted that the codified Fantasy Supplement rules in ‘Chainmail’ “beTraYs rEaL FaNs!” and sold out the hobby, but at least they couldn’t whinge on Reddit)

…but someone involved in 5e is has conjured the most obscurely brilliant bit of ultra-specific nerd humour I have seen in years.

Y’see, 5e modules don’t really do Rumour Tables or “If the party X, then Y, else Z” – DMs create dynamic worlds on the fly. (Hopefully).

So you’d think there’s no more chance of hilarious moments where the Goblins start yelling “Bree-Yark!” and Magnus Rushes In only to be shocked to find a well-bribed and high-Challenge Rating ogre running obediently up from Location E.22.

But you would think (slightly) wrong.

Because although 5e modules don’t do rumours the like 1e did, the Monster Manual does do flavour text – it’s usually a snippet of lore, or a word from a famous scholar, or advice from an adventurer who encountered the monster but lived to tell the tale. It provides fluffy depth.

A section of the D&D 5th Ed...

And, actually, I say “it’s usually” but I’ve just checked and every bit of flavourtext I can find in the Monster Manual is either By A Scholar, From a Book, An Adventurer’s Tale, or a Monster Describing Itself…

A section of the D&D 5th Ed...

…with one single exception: the flavourtext on the entry for Goblins, which isn’t attributed to anybody or anything, but is just the claim that “Bree-Yark!” means “we surrender!”

A section of the D&D 5th Ed...

This isn’t attributed to any source. Nobody in-lore has a citation for this. It’s just something “they say”. A genuine 1st Edition rumour just chilling out in the 5th edition Monster Manual three decades after B2 landed.

Glorious. Well played, @Wizards. Very well played.

Zoomed in view of the flavo...

Will swapping out electric car batteries catch on?

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

Without even a touch of the steering wheel, the electric car reverses autonomously into the recharging station

Underside of a car with a removable battery.

I won’t be plugging it in though, instead, the battery will be swapped for a fresh one, at this facility in Norway belonging to Chinese electric carmaker, Nio.

The technology is already widespread in China, but the new Power Swap Station, just south of Oslo, is Europe’s first.

This is what I’ve been saying for years would be a better strategy for electric vehicles. Instead of charging them (the time needed to charge is their single biggest weakness compared to fuelled vehicles) we should be doing battery swaps. A decade or two ago I spoke hopefully for some kind of standardised connector and removal interface, probably below the vehicle, through which battery cells could be swapped-out by robots operating in a pit. Recovered batteries could be recharged and reconditioned by the robots at their own pace. People could still charge their cars in a plug-in manner at their homes or elsewhere.

You’d pay for the difference in charge between the old and replacement battery, plus a service charge for being part of the battery-swap network, and you’d be set. Car manufacturers could standardise on battery designs, much like the shipping industry long-ago standardised on container dimensions and whatnot, to take advantage of compatibility with the wider network.

Rather than having different sizes of battery, vehicles could be differentiated by the number of serial battery units installed. A lorry might need four or five units; a large car two; a small car one, etc. If the interface is standardised then all the robots need to be able to do is install and remove them, however many there are.

This is far from an unprecedented concept: the centuries-old idea of stagecoaches (and, later, mail coaches) used the same idea, but with the horses being changed at coaching inns rather. Did you know that the “stage” in stagecoach refers to the fact that their journey would be broken into stages by these quick stops?

Anyway: I dismayed a little when I saw every EV manufacturer come up with their own battery standards, co=operating only as far as the plug-in charging interfaces (and then, only gradually and not completely!). But I’m given fresh hope by this discovery that China’s trying to make it work, and Nio‘s movement in Norway is exciting too. Maybe we’ll get there someday.

Incidentally: here’s a great video about how AC charging works (with a US/type-1 centric focus), which briefly touches upon why battery swaps aren’t necessarily an easy problem to solve.
