Hi, I'm Ronald (he/him), programmer, primarily Cobol and more recently Java. I'm also a #modelrailroading enthousiast.

Other interests: #woodworking, #electronics, #nature, #gardening, #food, #photography.

@Rowena Love it!

By the way: this rekindles the idea of setting up a garden model railway.
I don't have a huge garden but it's big enough for some fun on summer afternoons.

Friday is fun day on the West Coast Wilderness railway. Today the crew made up a goods train with a flat and a wagon and a real brake van then steamed it up and down the rack. They played trains all day long. We hates them and it's not fair. #trains #railways
@Rowena To be honest, I can't blame them. 😁 If I'd have that opportunity I'd do the same. 🚂
thank you everyone for the heads up about the super-old and now unmoderated instance we were on, we are here now ... ! THROWBACK THURS
@nekoow7 Check! 👍

@gulfie Yeah, that makes a lot of sense.

I once worked on a cobol backend system with a java based frontend; that might be another use case.

@gulfie What do cobol record definitions do in a java project? 🤔
@Adabei That car is a long way from home! 😳
@ivonnesmit.bsky.social I sure plan to! It's one of the few remaining shows worth putting the telly on for . 😒

Ed Zitron loves technology for what it could be.

He loathes Big Tech, especially the "AI" companies, for the unaccountable, destructive force it has become.

His newsletter, IMO, is a must-read. And today's installment, "AI is a Money Trap," is one of his best:

AI Is A Money Trap

In the last week, we’ve had no less than three different pieces asking whether the massive proliferation of data centers is a massive bubble, and though they, at times, seem to take the default position of AI’s inevitable value, they’ve begun to sour on the idea that

Just finished this 5-metre-long drystone seating area on the banks of a loch.

It stands about 1.5m tall and will hold a single piece of oak across the three protruding stones to form a bench.

The idea was to create something rooted in the land, not just placed on it. Sheltered, steady, and quietly purposeful. A place to pause and reflect.

Built by hand, no mortar, just time, attention, and stone. All materials sourced locally.

Drystone is pretty magic. Unbeatable sustainability credentials, an ancient craft with a global tradition, kind to flora and fauna....I could go on.

Feel free to ask me any questions and I will try to answer.

@kristiedegaris in the US any wall over 3.5' must be signed off on by a structural engineer. Do you ever use geofabric to layer back and stabilize the wall? Do you use an optical or laser level on your projects? Thx.

@donlamb_1

Geofrabric has been discussed on projects but never used.

Drystone is becoming more popular in the US I wonder if that rule applies to it too.

Honestly, with so much caefully placed stone, it doesn't need stabilised by anything else. It's 1.5 metres deep.

We use levels yes. We work with bars and string too to keep courses level and the batter of the wall correct.

@kristiedegaris Thanks for the info. Stone is much heavier than the typical masonry blocks they use here - makes sense. I'm sure the height rule applies. You often see a series of 3.5' high walls to avoid the requirement. I can really only speak for the rules in Colorado. Maybe not nationally.

@donlamb_1 @kristiedegaris dry stone walls can be seen throughout this country and some of them are 1.5 m tall and many have been standing there since centuries before any kind of fibre stabilisation was invented. They look vertical, but as Kristie says they all have a batter to ensure stability . It’s a very skilled job.
It’s only when you see them in cross section that you realise how stable they are.

And 2000 years ago, they built dry stone brochs three storeys high.

@donlamb_1 @kristiedegaris Want to site a source for that? I'm lawyer and I've never heard of a structural engineer being called in for boundary walls.
@DarleneCypser @kristiedegaris I'm talking any retaining wall in the State of Colorado. I'm a professional land surveyor and I've worked on thousands of projects in the last 40 years.
@donlamb_1 @kristiedegaris
Maybe you misunderstand what is being talked about. It's not a retaining wall. It is not load-bearing. It is a property boundary wall. It's like Robert Frost's "Good fences make good neighbors" wall.
I've been a lawyer in Colorado for 40+ years. Would love to know of any Colorado statute or regulation requiring a structural engineer to inspect any stone boundary fence within permitted limits. Never heard of it.

@kristiedegaris Very nice.

And on global influence, there are some drystone retaining walls preserved at the Georgetown Loop railway in Colorado, built by Cornish miners in the 1870s. The miners weren't trying to hold up tradition, it was just all they knew. But their handiwork has held up remarkably well.

@simonbp Oh that's very cool! Yes, drystone holds up incredibly well, we have 2000 year old drystone brochs here!
@kristiedegaris Thank you for this beautiful reference! I've been collecting stones on our lot and in looking at your fieldstone pile, well, I have a ways to go. Love the spirit of the endeavour.
@jmhnsn You are so welcome! The nice thing about drystone is that you can take your time, no rush at all.
@kristiedegaris I'm in good shape (for the shape I'm in), but "slow and steady finishes the race" is definitely my method for most things attempted.'
@kristiedegaris
Sort of question. On the coastal plain of NW Wales (Barmouth-Harlech) and probably elsewhere there are drystone walls made from smooth, rounded rocks collected from the beach. How the hell do they stay put? I've tried replacing one or two that have fallen, or been displaced by ramblers like me climbing over, and they just seem so wobbly and insecure. Do you have similar walls by the Scottish coast?
@pthane Some types of stone are harder to build with as it is quite round, but you can pin them in place with smaller stones (at the back and sides) if you find yourself struggling to get them to stay in place.
@kristiedegaris so I have a question. Regarding it being as deep as it is tall, and looking at the terrace photos further down, is a series of step like walls as strong as a single? Say 1mx1m wall Vs 3 30cmx30cm walls each one above and behind the last?

@econads

Terraced walls aren’t necessarily ‘stronger,’ but they’re often more stable on sloped ground. Instead of holding back a huge volume of soil all at once, they break the slope into smaller levels, which reduces pressure on each wall. It’s a way of working with the landscape instead of against it. A single big retaining wall on a hill has to withstand a lot more force. It’s riskier and can fail more dramatically if it goes.

This is my understanding anyway.

@kristiedegaris drystone seating area + a yap 😍
@kristiedegaris That is so beautiful, thank you.
@kristiedegaris that's stunning !
@richardinsandy Thank you! Drystone is just so gorgeous, nothing better really.
@kristiedegaris Great idea and beautifully executed!
@Star12Mt Thank you! It was built for a Buddhist retreat and will be in use soon. A memorial space, a place to reflect and think. It was a beautiful project to work on.
@kristiedegaris that’s incredible. Where is it?
@Mactonex Loch Voil.
@Mactonex Built for the Buddhist retreat there. It's a memorial space, a place to pause and reflect. Should be open to all at some point, I believe.
@kristiedegaris I cycled round there a few (many?) years ago. Beautiful part of Scotland.
@kristiedegaris
That's lovely. Do post again when it's got its plank laid.
@pthane I will for sure. Love to visit a project and see how it's doing.
@kristiedegaris beautifully done, looks lovely.
@wurzelmann Thank you! we're very pleased with it.
@kristiedegaris This is beautiful. I love how you’ve fit the differing sizes so tightly.
@mmb There was quite a lot of stone shaping on this job, but worth it!

@kristiedegaris

Wow, that’s really beautiful work! Will the ‘seats’ stay as is or are they intended to support a horizontal bench of some other material? Either way, it’s wonderful to know that people will be able enjoy that spot for a century or more.

@DavidM_yeg Thank you! There will be a piece of oak placed across them and secured (method still in discussion). And yes, building with drystone means creating such a tangible legacy and it's honestly an amazing feeling.
Ohhhh that’s gorgeous. How far into the bank do the seat stones run?!??!? @kristiedegaris

@clew The whole structure is over a metre deep. With anything that's retaining it should be as deep as it is tall.

Behind the face stones (the ones you can see) is a lot of other stone we call hearting or packing, every piece placed by hand. This is an incredibly strong structure.

@kristiedegaris wow. That’s beautiful and also very impressive
@kristiedegaris Wow, this is stunning! And in my opinion you nailed the „rooted in the land“ look.
@cyndakuiru Ah I'm so glad you think so!

@kristiedegaris Beautiful!

Can I ask how you are holding back the earthworks from behind the stone? It doesn't look like the stone is stable enough on it's own to hold back that much earth w/o rear support or something like vertical "rebar" or something... NOT trying to be judgy. I just can't see the methodology.

Is the earth actually more stone or clay and not just dirt?

@jgobble

It is a retaining wall so it is as deep as it is tall. There's over a metre of 'hidden' wall beneath the earth.

The earth is quite sandy in that spot as it is on the banks of a loch.

@kristiedegaris AHHHHH! GOT IT NOW!

Wow! *THAT'S* a project!

That's how we - back in Northern California - built earthen dams. Rock and soil as AT LEAST as deep as it is tall to protect surrounding homes from flooding from the fields when large floods occurred in the area.

@jgobble Yep, it's super effective.

@kristiedegaris

Absolutely beautiful! You should be so proud of that, very nice work indeed 👏

@FediThing We're really really pleased with it. Hard stone to work with in some ways but worth the extra effort.
@kristiedegaris As a former gardener who preferred to use natural stone, I love this piece. It's a beauty 💚
What kind of stone is this? (And how much work with the chisel did it take?)
@makeratschool Thank you! This is a sandstone but it's a bit more of a hard sandstone, brittle at times. So it was quite difficult to shape sometimes, worth it in the end. There was quite a lot of shaping on this job.
