we don't use leagues or furlongs. I know what a chain is because i have one, but that's specifically to measure land against a plat map. Every location in this country is based off common reference locations (there's a literal marker on the ground), with only chains and angles to delimit things (generally). Read that last part again, because they use GPS to determine if the marker has moved, and that takes X minutes…

Every location in this country is based off common reference locations (there's a literal marker on the ground) The same holds for more obscure unit prefixes in the SI system like dam (decameter) or hm (hectometer) in the SI unit system (as far as I am aware, the only common usage…

I forgot one thing. you said "why not have in^2 and in^3" we do, but we don't use that very often. Older American "muscle cars" engines' displacement was measured in cubic inches. every child learns what a square inch is. a "board foot" is 12 cubic inches of milled wood, 12 in^3 - I don't know how to verify this on a Sunday, so this may be wrong, the board-foot. And then, we use square feet; for floor space in a house, say, my house is ~1500 ft^2. We also use cubic yards, yd^3, for stuff like dirt, concrete. when talking about this, like if i need a driveway's worth of concrete, the load is measured in "yards" which is short for "cubic yards."

But all that aside, and with apologies to mods and you for sneering; i wanted to say this in my prior reply but when reading it aloud to my wife i took it out:

Americans can, in general, divide and multiply by numbers other than 10.

yes, we use acres and hectares, too! it sounds better to say i live on 6.5 acres to an American neighbor who asks, than 0.02630457km^2...

These kits can have extraordinary longevity. I was playing with Lincoln Logs in 1967. Turns out they got started in 1918. Lego bricks have been around since 1945. The moat created by seriously delighting your customers at a young age is large.

> The moat created by seriously delighting your customers at a young age is large. I wish Meccano would get its shit together. I can’t see anything I want on their limited site and there is so much cool stuff that could be made. https://www.meccano.com/

You may found them on the Eitech website. It is a german compatible brand. https://www.eitech.de/en

Indeed Amazon is chock full of shitty Chinese Lego ripoffs. The bricks do indeed fit together but the quality is abysmal.

Some of the Chinese brands have superior quality to LEGO these days.

Partly because the chinese produce the plastic that Lego use.

This is probably the case of a bodged migration from one CMS to another. My blog suffered the same, and going through loads of old pages to check and fix them just isn't worth the effort.

Yeah this really looks like an encoding issue during migration. I've run into similar problems when moving old content between systems, especially with MySQL and mixed encodings. It can get messy surprisingly quickly.

If you used UTF-8 then you can probably fix those pretty easily. UTF-8 is sufficiently structured that it’s extremely unlikely for a string that’s written in another encoding to be valid UTF-8 by accident. If you write some code to try decoding as UTF-8 and set that as the encoding when it succeeds, you’re unlikely to damage anything in the process.

It is a really nice concept. I had never heard of it. But then as GenX at young age I played with Fishertechnik [0] more than with Lego. Around since 1966 [1]. [0] https://www.fischertechnik.de/en [1] https://en.wikipedia.org/wiki/Fischertechnik

Construx is what I played with. It was only sold for a few years.

I too had construx. I probably used them more than Lego because they were better suited for large structures. It's a shame they don't make them any more.

Any zometool aficionados here https://www.georgehart.com/virtual-polyhedra/zometool.html

Back many years ago, yes... and I recently stumbled across it again in a Henry Segerman video about expanding racks in three dimensions https://youtu.be/NEJZlGuWGV8

Loved the video. Thanks.

That's an awesome project. I'm sure there are many kids that have been gifted LEGO knockoffs that are not compatible with legos from adults that didn't know any better. A similar "interop" project for those would be great

Almost all (back then, I hear the clone quality is much higher now) were "compatible" but had little to no clutch power, a wall built with some of them would inevitably break at the clone bricks.

I don't mean lego knockoffs. I mean legal alternatives to lego. Yes I've heard modern Lepin often exceeds real LEGO in quality

> Note: all units are in inches. Not so universal as I'd hoped, but I love the concept and the organization behind it, Free Art and Technology Lab.

There's this universal constant 2.54 you can use it to divide any value in inches and badabing you get the value in centimeters

This answer is worth at least 3.14 badabings, couple of twips and a barleycorn
