Geohashing expedition 2022-10-24 51 -1

This checkin to geohash 2022-10-24 51 -1 reflects a geohashing expedition. See more of Dan's hash logs.

Location

Wharf Stream Way, Eynsham. I’ve visited this circular footpath many times to walk the dog or to take the children to swim in the river.

Participants

Plans

I hope to cycle/walk to the GZ about lunchtime? I’ve an opportunity to pass nearby the GZ between other errands this morning!

Expedition

I was excited to see this spot pop up on my radar, because it’s a lovely meadow that I’ve ocassionally walked my dog in, within comfortable cycling distance of my house. As it happened, I had an even easier route here because a drive this morning to drop the kids off at a half-term activity took me “close enough” to be worth stopping and walking from there.

I parked at The Talbot Inn, just West of the Swinford Toll Bridge (a bizzare old bridge that, for weird historical reasons, continues to use human operators to charge 5 pence per car to cross, which surely cannot be cost-effective!). From here, there’s a footpath along the back of the Seimens buildings in the nearby light industrial estate which eventually comes out into the Wharf Stream Way circular walk. It was pretty damp out here today and I quickly regretted my choice of light trousers which would have been fine to drive the kids to their camp and back but wasn’t really a good choice for stomping across the long grass of a damp meadow. Some way across I disturbed some grazing deer, but ultimatey it was following a deer-trodden trail that eventually provided the best route to the GZ.

I reached the GZ at 09:19, took a selfie, and then turned around to go and get to work. I also shot a video covering the whole expedition which is presented, unedited, below.

Tracklog

My GPSr kept a tracklog; note that this was an “on the way” stopoff so the start and end point isn’t the same!

Dan Q found GC88Z3D SANT PAU DEL CAMP

This checkin to GC88Z3D SANT PAU DEL CAMP reflects a geocaching.com log entry. See more of Dan's cache logs.

Found with fleeblewidget during a meander around the city. She saw it ahead and remarked on the beautiful building before I’d even told her that was where we were heading. Greetings from Oxford, UK. Gracias por el caché.

How Chinese citizens use puns to get past internet censors

This 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.

Bisect your Priority of Constituencies

Your product, service, or organisation almost certainly has a priority of constituencies, even if it’s not written down or otherwise formally-encoded. A famous example would be that expressed in the Web Platform Design Principles. It dictates how you decide between two competing needs, all other things being equal.

At Three Rings, for example, our priority of constituencies might1 look like this:

  1. The needs of volunteers are more important than
  2. The needs of voluntary organisations, which are more important than
  3. Continuation of the Three Rings service, which is more important than
  4. Adherance to technical standards and best practice, which is more important than
  5. Development of new features

These are all things we care about, but we’re talking about where we might choose to rank them, relative to one another.

Semicircular illustration showing five facets of growing relative importance. From least to most, they are: new features, standards-compliance, service continuity, organisation needs, volunteer needs.
The priorities and constituencies portrayed in this illustration are ficticious. Any resemblence to real priorities and constituencies, whether living or dead, is entirely coincidental.

The priorities of an organisation you’re involved with won’t be the same: perhaps it includes shareholders, regulatory compliance, different kinds of end-users, employees, profits, different measures of social good, or various measurable outputs. That’s fine: every system is different.

But what I’d challenge you to do is find ways to bisect your priorities. Invent scenarios that pit each constituency against itself another and discuss how they should be prioritised, all other things being equal.

Using the example above, I might ask “which is more important?” in each category:

  1. The needs of the volunteers developing Three Rings, or the needs of the volunteers who use it?
  2. The needs of organisations that currently use the system, or the needs of organisations that are considering using it?
  3. Achieving a high level of uptime, or promptly installing system updates?
  4. Compliance with standards as-written, or maximum compatibility with devices as-used?
  5. Implementation of new features that are the most popular user requests, or those which provide the biggest impact-to-effort payoff?
Illustrated priority list from above, which each item split into two and re-named such that they are, from least to most important: popular features, impact features, compliance, usability, uptime, updates, future clients, current clients, other volunteers, our volunteers.
These might not be your answers to the same questions. They’re not even necessarily mine, and they’re even less-likely to be representative of Three Rings CIC. It’s just illustrative.

The aim of the exercise isn’t to come up with a set of commandments for your company. If you come up with something you can codify, that’s great, but if you and your stakeholders just use it as an exercise in understanding the relative importance of different goals, that’s great too. Finding where people disagree is more-important than having a unifying creed2.

And of course this exercise applicable to more than just organisational priorities. Use it for projects or standards. Use it for systems where you’re the only participant, as a thought exercise. A priority of constituencies can be a beautiful thing, but you can understand it better if you’re willing to take it apart once in a while. Bisect your priorities, and see what you find.

Footnotes

1 Three Rings doesn’t have an explicit priority of constituencies: the example I give is based on my own interpretation, but I’m only a small part of the organisation.

2 Having a creed is awesome too, though, as I’ve said before.

Dan Q performed maintenance for GC88ZY9 The Devil’s Quoits

This checkin to GC88ZY9 The Devil's Quoits reflects a geocaching.com log entry. See more of Dan's cache logs.

A fringe benefit to being CO to a virtual is that it doesn’t require much maintenance, save for ensuring that all logs are accompanied by a valid solution message and no spoilers are posted. But it’s still worth visiting them from time to time to ensure they’re still accessible and solvable! These stones have been here for thousands of years – minus a relatively short period from around the 15th to the 20th centuries! – so I couldn’t imagine they’d gone anywhere, and indeed they haven’t. Counted them to make sure, and the geopup checked that the outlier stone was in its proper place. Maintenance performed!

A French Bulldog runs towards the camera, her tongue hanging out, in a grassy field. Standing stones can be seen in the background, under a blue sky.

Kids: We want porridge for breakfast.
Me: How do you want it?
Kids: Surprise us.

Presenting… oatmeal, honey and sultanas with a toasted marshmallow.

My First MP3

Duration

Podcast Version

This post is also available as a podcast. Listen here, download for later, or subscribe wherever you consume podcasts.

Somebody shared with me a tweet about the tragedy of being a Gen X’er and having to buy all your music again and again as formats evolve. Somebody else shared with me Kyla La Grange‘s cover of a particular song .Together… these reminded me that I’ve never told you the story of my first MP31

Screenshot of tweet by @bewgtweets posted Oct 17, 2021, reading: If you want to know why Gen X’ers are always mad it’s because we had to replace our record collections with a tape collection that was then replaced with a cd collection that was then replaced with MP3’s and damn it how many time must I pay to listen to grunge
I didn’t/don’t own much vinyl – perhaps mostly because I had a tape deck in my bedroom years before a record player – but I’ve felt this pain. And don’t get me started on the videogames I’ve paid for multiple times.

In the Summer of 1995 I bought the CD single of the (still excellent!) Set You Free by N-Trance.2 I’d heard about this new-fangled “MP3” audio format, so soon afterwards I decided to rip a copy of the song to my PC.

I was using a 66MHz 486SX CPU, and without an embedded FPU I didn’t quite have the spare processing power to rip-and-encode in a single pass.3 So instead I first ripped to an uncompressed PCM .wav file and then performed the encoding: the former step was done almost in real-time (I listened to the track as it ripped!), about 7 minutes. The latter step took about 20 minutes.

So… about half an hour in total, to rip a single song.

Dan, as a teenager, sits at a desk with his hand to his chin. In the foreground, a beiege two-button wired ball-type computer mouse rests on the corner of the desk. Dan is wearing a black t-shirt with a red devil face printed onto it.
Progress bar, you say? I’ll just sit here and wait then, I guess. Actual contemporary-ish photo.

Creating a (what would now be considered an apalling) 32kHz mono-channel file, this meant that I briefly stored both a 27MB wave file and the final ~4MB MP3 file. 31MB might not sound huge, but I only had a total of 145MB of hard drive space at the time, so 31MB consumed over a fifth of my entire fixed storage! Even after deleting the intermediary wave file I was left with a single song consuming around 3% of my space, which is mind-boggling to think about in hindsight.

But it felt like magic. I called my friend Gary to tell him about it. “This is going to be massive!” I said. At the time, I meant for techy people: I could imagine a future in which, with more hard drive space, I’d keep all my music this way… or else bundle entire artists onto writable CDs in this new format, making albums obsolete. I never considered that over the coming decade or so the format would enter the public consciousness, let alone that it’d take off like it did.

A young man in jeans and a blue coat stands on the patio in the back garden of a terraced house, dropping a half-brick onto the floor. In the background, an unused rabbit hutch and a dustbin can be seen. The photo is clearly taken using a flash, at night.
If you’re thinking of Gary and I as the kind of reprobates who helped bring on the golden age of music piracy… I’d like to distract you with a bigger show of yobbish behaviour in the form of this photo from the day we played at dropping half-bricks onto starter pistol ammunition.

The MP3 file I produced had a fault. Most of the way through the encoding process, I got bored and ran another program, and this must’ve interfered with the stream because there was an audible “blip” noise about 30 seconds from the end of the track. You’d have to be listening carefully to hear it, or else know what you were looking for, but it was there. I didn’t want to go through the whole process again, so I left it.

But that artefact uniquely identified that copy of what was, in the end, a popular song to have in your digital music collection. As the years went by and I traded MP3 files in bulk at LAN parties or on CD-Rs or, on at least one ocassion, on an Iomega Zip disk (remember those?), I’d ocassionally see N-Trance - (Only Love Can) Set You Free.mp34 being passed around and play it, to see if it was “my” copy.

Sometimes the ID3 tags had been changed because for example the previous owner had decided it deserved to be considered Genre: Dance instead of Genre: Trance5. But I could still identify that file because of the audio fingerprint, distinct to the first MP3 I ever created.

I still had that file when I went to university (where it occupied a smaller proportion of my hard drive space) and hearing that distinctive “blip” would remind me about the ordeal that was involved in its creation. I don’t have it any more, but perhaps somebody else still does.

Footnotes

1 I might never have told this story on my blog, but eagle-eyed readers may remember that I’ve certainly hinted at it before now.

2 Rewatching that music video, I’m struck by a recollection of how crazy popular crossfades were on 1990s dance music videos. More than just a transition, I’m pretty sure that most of the frames of that video are mid-crossfade: it feels like I’m watching Kelly Llorenna hanging out of a sunroof but I accidentally left one of my eyeballs in a smoky nightclub and can still see out of it as well.

3 I initially tried to convert directly from red book format to an MP3 file, but the encoding process was too slow and the CD drive’s buffer filled up and didn’t get drained by the processor, which was still presumably bogged down with framing or fourier-transforming earlier parts of the track. The CD drive reasonably assumed that it wasn’t actually being used and spun-down the drive motor, and this caused it to lose its place in the track, killing the whole process and leaving me with about a 40 second recording.

4 Yes, that filename isn’t quite the correct title. I was wrong.

5 No, it’s clearly trance. They were wrong.
